The configurations described in this block diagram are the same in the second to fifth embodiments described later.
In this figure, the code | symbol 1 represents the plant operation training apparatus. The plant operation training apparatus 1 can reproduce the plant and the avatar, which is a part of the user, in the 3D virtual space using those 3D model data, and simulate the operation training of the equipment provided in the plant for the user. It is a device that provides functions that can be performed. The plant operation training device 1 is, for example, a PC or a server device that can execute a program that realizes this function.

Reference numeral 2 denotes a plant simulation apparatus. The plant simulation device 2 is a device that simulates the behavior of the plant by calculating state quantities such as an output of a gas turbine, a pressure in the compressor, and a temperature provided in the plant. The plant simulation apparatus is connected to the plant operation training apparatus 1 via a network. The plant operation training apparatus 1 receives a signal indicating the operation content performed by the avatar on the devices, and simulates the behavior of the plant based on the content. The signal indicating the operation content includes, for example, information indicating opening / closing of a valve and turning on / off of a certain control device. The plant simulation device 2 transmits the calculated state quantity and the like to the plant operation training device 1. The user performs an operation simulating causing the avatar of the plant operation training apparatus 1 to check the indicator provided in the plant, and knows what result is obtained by the operation performed by the user through the avatar. In this way, the user can learn the operation of the equipment provided in the plant.
The plant simulation apparatus 2 is also connected to a training simulation apparatus (not shown) that simulates the central control room. The plant simulation apparatus 2 receives a user operation using the simulation apparatus in the central control room and similarly simulates the behavior of the plant.
The plant operation training apparatus 1 is a part of the plant operation training system configured as described above.

As shown in FIG. 1, the plant operation training apparatus 1 includes a display unit 10, an operation unit 20, a virtual space generation unit 30, a storage unit 40, and a communication unit 50.
The display unit 10 is a monitor such as a PC, a screen projected by a projector, or the like. The user looks at the 3D image of the equipment in the plant output to the display unit 10 and performs an operation necessary for training.
The operation means 20 is a mouse, a game controller, a joystick or the like. The user controls the operation of the avatar using these operation means. In this embodiment, an operation using not only a mouse but also a game controller or a joystick is possible. As a result, the user can smoothly move through the plant represented in the 3D virtual space and can receive training with a more realistic feeling. In particular, when training is performed by displaying a 3D image on a large screen, the distance between the hand and the screen is increased, which makes operation with a mouse difficult. In the present embodiment, the 3D image provided by the plant operation training device 1 is not an object selected using the operation means 20 so that it can be easily operated even when a large screen is used. When the user approaches, the operation target interface screen is displayed, and the operation using the game controller is facilitated.

The virtual space generation unit 30 reads the 3D plant model data and the 3D human model data from the storage unit 40, and reproduces the state of the plant and the avatar in the 3D virtual space. In addition, an operation signal is acquired from the operation unit 20, the avatar is operated according to the user's operation, a 3D image of the place where the avatar has moved is generated, and is output to the display unit 10. The virtual space generation unit 30 includes a positional relationship calculation unit 31, a detailed screen display control unit 32, a corresponding part display control unit 33, a detailed screen display selection unit 34, a detailed screen selection setting unit 35, and a parameter acquisition unit 36. Yes.

The positional relationship calculation unit 31 calculates the positional relationship between the avatar and the devices provided in the plant. The equipment provided in the plant refers to large facilities such as turbines and boilers, and operating devices and indicators provided in these facilities. The positional relationship refers to the distance between the avatar and the devices, whether the avatar exists in a closed space (such as a room) provided with the devices, or whether the avatar is facing the devices.

When the calculation result of the positional relationship calculation unit 31 satisfies a predetermined condition, the detailed screen display control unit 32 displays an interface detailed screen of an operation device or a display device in a positional relationship that satisfies the predetermined condition at a predetermined position. The interface detail screen is an image enlarged so that the user can read the interface of the operation device or the display device. The values of various parameters displayed on the interface are values acquired from the plant simulation apparatus 2. The model data of the interface detail screen is stored in the storage unit 40 in association with the position information of the position where the device having the interface is provided.

Corresponding part display control unit 33 displays a part provided with a display or an operation unit having an interface indicated by the interface detail screen displayed by detailed screen display control part 32 in a manner different from other devices. An aspect different from other devices means that only the part is blinked or displayed in a conspicuous color. In addition, the corresponding part display control unit 33 may display the large facility equipment itself provided with a display device and an operation device in a different manner.

The detailed screen display selection unit 34 provides a user with a means for selecting an interface detailed screen displayed by the detailed screen display control unit 32. Specifically, the detailed screen display selection unit 34 displays the interface detailed screens of a plurality of devices in a predetermined position on the display unit 10 and selects whether or not to display sequentially from the detailed screen displayed in the foreground. Prompt the user. The detailed screen display selection unit 34 provides a function for preventing display of unnecessary interface details screens of equipment when there are many instruments at a certain plant location.

The detailed screen selection setting unit 35 provides a function of specifying an interface detail screen of selectable devices displayed by the detailed screen display selection unit 34 and setting the result. The detail screen selection setting unit 35 provides a function for setting not to display the interface detail screen of the device that is not used by the user. The equipment that is not used by the user is, for example, equipment that determines that a training instructor is unnecessary according to the level of the user who receives plant operation training, or equipment that should be used only in an emergency or emergency.

The parameter acquisition unit 36 requests the parameter value to be displayed on the interface from the plant simulation apparatus 2 when the detailed screen display control unit 32 starts displaying the interface detailed screen. The parameter acquisition unit 36 requests a parameter value via the communication unit 50 and acquires the parameter value from the plant simulation apparatus 2. The parameter value is a state quantity such as the pressure and temperature of the plant calculated by the plant simulation apparatus 2. The plant simulation apparatus 2 calculates the pressure, temperature, and the like at the position where the gauges and thermometers provided in the plant are provided, and the state quantity is obtained according to the request of the parameter acquisition unit 36. Send to 1. In the plant operation training apparatus 1, the detail screen display control unit 32 displays the interface detail screen of each device in which the parameter value acquired by the parameter acquisition unit 36 is set.
In addition, the parameter acquisition part 36 will transmit the signal which shows the operation content to the plant simulation apparatus 2 via the communication part 50, if a user operates with respect to an operating device via an avatar.

The storage unit 40 stores plant 3D model data, human 3D model data, equipment interface detail screen model data, and the like. In addition, the setting contents by the detailed screen selection setting unit 35 are also stored. Note that the model data on the device interface detail screen may be 2D image data.
The communication unit 50 communicates with other devices. The communication part 50 transmits / receives the parameter value information of the plant state quantity, for example.
The virtual space generation unit 30 is a function provided when a CPU (Central Processing Unit) provided in the plant operation training apparatus 1 executes a program.

FIG. 2 is a diagram showing each display area on the operation screen of the plant operation training apparatus 1 according to the present embodiment. The regions described here are the same in the second to fifth embodiments.
The position and meaning of displaying the interface detail screen will be described with reference to FIG.
Reference numeral 104 denotes an area where the detailed screen display control unit 32 displays the interface details screen of the devices. Hereinafter, this area is referred to as an operable area. The device interface detail screen displayed in the operable area 104 is a user's operation target.
Reference numeral 105 denotes an area where the detail screen display selection unit 34 displays the interface detail screen in an overlapping manner. Hereinafter, this area is referred to as a selection area. The detailed screen display control unit 32 displays only the interface image of the device selected by the user from the device options displayed in the selection area 105 by the detailed screen display selection unit 34 in the operable area.
Reference numeral 106 denotes an area for displaying an interface detail screen that is not selected by the user. Hereinafter, this area is referred to as an operation impossible area.
Reference numeral 107 denotes an interface details screen. In the interface image, an interface of a display device or an operation device is displayed. The user can know the state of the plant by looking at the interface detail screen 107 of the display. The user can operate the device using the operation means 20 on the interface detail screen 107 of the operation device.

FIG. 3 is a diagram showing an operation screen of the plant operation training apparatus 1 according to the present embodiment.
An operation in which the detailed screen display control unit 32 displays the interface detail screen 107 of the operation device or the display device according to the positional relationship calculated by the positional relationship calculation unit 31 will be described with reference to FIG.
Reference numeral 100 is a 3D image simulating a certain place inside the plant. Reference numeral 101 denotes an avatar. It is assumed that the avatar 101 has reached the place 100 in the plant by the operation of the operation means 20 by the user. When the virtual space generation unit 30 acquires the operation signal from the operation unit 20, the virtual space generation unit 30 calculates the movement distance based on the position before the operation of the avatar 101. The movement distance may be calculated, for example, so as to advance a predetermined distance every time a predetermined button is pressed. The virtual space generation unit 30 calculates position information of the avatar in the plant every time the avatar 101 moves and outputs it to the memory. In addition, the virtual space generation unit 30 reproduces the scenery of the plant near the position based on the position information of the movement destination of the avatar 101. The place 100 is a 3D image generated by the virtual space generation unit 30 in this way. The plant 3D model data stored in the storage unit 40 includes position information of the equipment in the plant.
Each time the avatar 101 moves, the positional relationship calculation unit 31 calculates the distance between the avatar 101 and the devices provided in the plant using the respective position information in the plant.

In FIG. 3, it is assumed that a high-pressure feed water flow meter 102 and a high-pressure feed valve rear valve 103 are provided in the vicinity of the place 100. When the avatar 101 reaches the place 100, it is assumed that the distance between the avatar 101, the high-pressure water supply flow meter 102, and the high-pressure water supply valve rear valve 103 is within a predetermined distance (first threshold).
Then, the detailed screen display control unit 32 acquires the model data of the interface detailed screen of the high-pressure feed valve rear valve and the high-pressure feed flow meter from the storage unit 40 and displays the interface detail screen 107 in the operable area 104. The interface detail screen 107 of the high-pressure feed water flow meter 102 and the interface detail screen 107 of the high-pressure feed valve rear valve 103 are displayed in the operable area 104 so as to overlap the front of the plant 3D image.
The user can grasp what value the high-pressure feed water flow meter 102 indicates from the interface detail screen 107. The user can adjust the opening / closing degree of the high-pressure water supply valve rear valve 103 and change the flow rate by operating the interface detail screen 107 using the operation means 20.

In the conventional 3D simulation driving training apparatus, for example, when performing a valve opening / closing operation, the mouse is first moved to the vicinity of the 3D image of the valve, the valve is selected by a click operation, and further a valve opening / closing instruction is performed by a click operation or the like. When the operation is completed, it is necessary to close the window by clicking the X mark at the upper right corner of the valve image window.
However, if such an operation is necessary, it is difficult for the user to grasp the positional relationship between the operator and the equipment that can be obtained by an actual operator in an actual plant, and the user is less likely to feel realism and train. The effect is also considered to be affected.
According to the present embodiment, the user moves the avatar 101, and the detailed screen display control unit 32 displays the interface details screen of the device just by approaching the device that is the subject of the operation training. There is no need to perform any special operations. Therefore, the user can grasp the positional relationship with the devices and can work on driving training with a more realistic feeling.
In this embodiment, it is possible to use not only a mouse but also a game controller. While many 3D role-playing games and the like that are more realistic are provided, a game controller developed as a more suitable operation means can be used in the 3D virtual space in the plant by the plant operation training apparatus 1. It is possible to move smoothly and bring driving training closer to real training.
Further, when the game controller is used, it is difficult to perform an operation in which the user selects a device to be operated. However, since the interface details screen 107 of the device is displayed only when the avatar 101 approaches the devices as described above, no selection operation is necessary. To move the avatar 101 with the game controller, for example, a joystick is used.

In FIG. 3, the operation when the avatar 101 approaches the device has been described. Hereinafter, an operation in which the detailed screen display control unit 32 hides the interface detailed screen 107 when the avatar 101 leaves the device will be described. Even when the avatar 101 moves and leaves the device, the positional relationship calculation unit 31 calculates the distance between them. The detailed screen display control unit 32 hides the interface detailed screen 107 displayed in the operable area 104 when the distance between the avatar 101 and the device is equal to or greater than the second threshold.
The user can hide the interface detail screen 107 that is not used simply by moving the avatar 101 away from the device, and does not need to perform complicated operations.
Next, the operation of the operation device displayed on the interface detail screen 107 will be briefly described. In FIG. 3, it is assumed that the interface detail screen 107 of the high-pressure feed water flow meter 102 is currently active by a user's predetermined operation. Active means that it is in a state of accepting a user operation. In order to operate the high-pressure water supply valve rear valve 103 from this state, the user switches the active interface detail screen 107 by pressing the right key of the cross key of the game controller, for example. Then, the interface detail screen 107 of the high pressure water supply valve rear valve 103 becomes active. Next, the user opens and closes the high-pressure water supply valve rear valve 103 using the up and down buttons of the cross key, for example.
According to the present embodiment, it is possible to move the avatar, display / hide the device interface, and operate the operation device with a simple operation.

In the above example, the display / non-display determination of the interface detail screen 107 is determined by the distance between the avatar 101 and the device, but in addition to that, the orientation of the avatar 101 may be added to the determination. For example, even if the device is provided near the avatar 101, the device provided on the back side of the user is not displayed. Further, even if the device is displayed in the operable area 104, the interface detail screen 107 may be hidden when the avatar 101 faces in another direction. As a result, the user can learn the position where the devices are installed more accurately.
In addition, when the equipment is provided in a room, the position information of the avatar 101 is compared with the position information of the room in which the equipment is provided, and when the avatar 101 enters the room, the room is provided. The device interface detail screen 107 may be displayed in the operable area 104. Further, the interface detail screen 107 may be hidden when the avatar 101 leaves the room.

FIG. 4 is a first diagram showing a processing flow of the display device according to the present embodiment.
FIG. 5A is a first diagram used for explaining the processing flow of the plant operation training apparatus according to the first embodiment of the present invention. FIG. 5B is a second diagram used for explaining the processing flow of the plant operation training apparatus according to the first embodiment of the present invention.
The processing described in FIG. 3 will be described in detail using the processing flow in FIG.
First, the positional relationship calculation part 31 acquires the combination of the apparatus (each operation device and indicator) in a plant, and its positional information from the memory | storage part 40 (step S1). Here, the position information is three-dimensional coordinate information. At this time, the positional relationship calculation unit 31 may acquire the position information of the devices of the entire plant, or only the position information of the devices provided within a predetermined distance based on the route along which the avatar 101 moves. You may acquire one after another. The positional relationship calculation unit 31 counts the total number of acquired devices and stores it in the memory.
FIG. 5A is a diagram illustrating an example of a table read by the positional relationship calculation unit 31 in step S1. This table is held in the storage unit 40. The positional relationship calculation unit 31 includes an “TAG” field in which the identifier of the device is stored from the table shown in FIG. 5A and an “X coordinate”, “Y coordinate”, and “Z coordinate” column that indicate the position information of the device in the plant. Get the value and store it in memory.

Next, the virtual space generation unit 30 acquires user operation information from the operation means 20 and moves the avatar 101 to a place corresponding to the operation information. The virtual space generation unit 30 reads the 3D model data of the plant from the storage unit 40 and generates a 3D image showing a scene entering the field of view from the position where the avatar 101 has moved. Then, the virtual space generation unit 30 outputs the newly generated 3D image to the display unit 10. In addition, the virtual space generation unit 30 outputs position information of a place where the avatar 101 exists to the memory. The positional relationship calculation part 31 acquires the positional information in the plant of the avatar 101 from memory (step S2).

Next, the positional relationship calculation unit 31 uses the positional information acquired in steps S1 and S2 to determine the avatar 101 and the device i for one of the devices (operator or display) acquired in step S1 (device i). The distance i which is the distance of is calculated (step S3). The distance i is {(X2-X1) ² + (Y2), where (X1, Y1, Z1) is the position information of the place where the avatar 101 exists and (X2, Y2, Z2) is the position information of the device i. It can be obtained by calculating the square root of -Y1) ² + (Z2-Z1) ² }.
Next, the positional relationship calculation unit 31 compares the distance i calculated in step S3 with a predetermined first threshold (step S4). When the distance i is smaller than the first threshold (step S4 = Yes), the positional relationship calculation unit 31 outputs the identifier of the device i to the detailed screen display control unit 32. The first threshold is a value used to determine whether or not the avatar 101 displays the interface detail screen 107 of the device i.

The detailed screen display control unit 32 determines whether the interface detailed screen 107 of the device i indicated by the acquired identifier has already been displayed (step S5).
An example of the determination method in step S5 will be described with reference to FIG. 5B. FIG. 5B shows an example of a table that is referred to when the detailed screen display control unit 32 determines whether the interface detailed screen 107 of the device i has already been displayed. In this figure, if the value of the “displayed flag” field is “0”, it indicates that the interface detail screen 107 of the device having the “TAG” field of the record as an identifier is not displayed in the operable area. A value of “1” indicates that the interface image of the device has already been displayed in the operable area.
Returning to the processing flow of FIG. When the interface detail screen 107 of the device i has already been displayed (step S5 = Yes), the detail screen display control unit 32 does not display the interface detail screen 107 of the device i. The case where the interface detail screen 107 of the device i is already displayed may be a case where the avatar 101 approaches the device i and moves back and forth (the range not exceeding the second threshold described later). .
When the interface image of the device i has not been displayed yet (step S5 = No), the detailed screen display control unit 32 stores image data indicating the interface details screen 107 of the operation unit or display corresponding to the identifier of the device i. The data is read from 40 and displayed in the operable area of the display unit 10 (step S6). For example, at this time, the detailed screen display control unit 32 reads the table of FIG. 5A using the identifier (“TAG”), and acquires the value of the “interface image data” column of the corresponding record. Then, the detailed screen display control unit 32 specifies the image data indicated by this value, and generates the interface detailed screen 107 of the device i based on the specified image data. When the detailed screen display control unit 32 completes these processes, it outputs a signal indicating that the process has been completed to the positional relationship calculation unit 31.

Next, the positional relationship calculation unit 31 determines whether or not the calculation of the positional relationship (distance) has been completed for all the operating devices and displays acquired in step S1 (step S10). When the calculation has been completed for all the devices (step S10 = Yes), this processing flow ends. When that is not right (step S10 = No), the process from step S3 is repeated about the following apparatus.
The case where the distance between the position of the avatar 101 and the position of the device i is smaller than the first threshold in step S4 has been described so far. The case where the distance between the avatar 101 and the device i + 1 is equal to or larger than the first threshold for the device i + 1 to be processed in the present processing flow (step S4 = No) will be described below. In this case, the detailed screen display control unit 32 does not display the interface detailed screen 107 of the device i + 1.
The positional relationship calculation unit 31 compares the distance i + 1, which is the distance between the avatar 101 and the device i + 1, with the second threshold value (step S7). The second threshold is a value used to determine whether or not to hide the interface detail screen 107 when the avatar 101 moves away from the device i.
When the distance i + 1 is smaller than the second threshold (step S7 = No), the process for the device i + 1 is completed (the device i + 1 is not particularly performed), and the determination in step S10 is performed.
When the distance i + 1 is equal to or greater than the second threshold (step S7 = Yes), the positional relationship calculation unit 31 outputs information indicating the identifier of the device i + 1 to the detailed screen display control unit 32.

Next, the detailed screen display control unit 32 determines whether or not the interface detailed screen 107 of the device i + 1 indicated by the acquired identifier is already displayed in the operable area (step S8). The determination method may be the same as in step S5. When the interface image of the device i is not displayed (step S8 = No), the positional relationship calculation unit 31 is notified of the completion of the process. When the interface image of the device i + 1 is displayed (step S8 = Yes), the detailed screen display control unit 32 displays the interface details screen 107 of the operation device or display device corresponding to the identifier of the device i + 1 displayed in the operable area. Is performed (step S9). When the detailed screen display control unit 32 completes these processes, it outputs a signal indicating that the process has been completed to the positional relationship calculation unit 31.
Next, the positional relationship calculation part 31 performs determination of step S10. When the control for displaying / hiding interface images for all devices is completed as described above, this processing flow ends.

When the virtual space generation unit 30 moves the avatar to the place 100 based on the signal from the operation means 20, the detailed screen display selection unit 34 selects the interface detail screen 107 of the device provided at a distance within the first threshold from the avatar 101. Display in area 105. FIG. 6 is a 3D image when the avatar 101 is present at the plant location 100. In FIG. 6, it is assumed that the high pressure feed valve rear valve 103 and the high pressure feed water flow meter 102 are provided within a distance smaller than the first threshold value from the avatar 101. At this time, the detail screen display selection unit 34 displays the interface detail screen 107 of the high-pressure feed water flow meter 102 and the interface detail screen 107 of the high-pressure feed valve rear valve 103 in the selection area 105 of the display unit 10 in an overlapping manner. Further, the detailed screen display selection unit 34 displays, for example, a red frame 111 indicating that it is a target for accepting an operation from the user on the outer frame of the interface detail screen 107 of the device displayed on the forefront.

When the user performs an operation of selecting a device in this state, the detailed screen display control unit 32 moves and displays the interface detailed screen 107 in the operable area. Further, when the user performs an operation without selecting a device, the detailed screen display selection unit 34 deletes the interface detail screen 107 from the selection area, and displays another interface detail screen 107 displayed below the frontmost screen. To display. Here, the predetermined operation may be, for example, pressing a predetermined button of the game controller or performing a click operation with a mouse.
Further, when the user performs another predetermined operation indicating that the device is not selected, the detail screen display selection unit 34 deletes the interface detail screen 107 from the selection area 105 and displays the next interface detail screen 107 in the selection area. 105 is displayed on the foreground.
The result selected by the user is stored in the storage unit 40 by the detailed screen display selection unit 34.

Thus, by not displaying devices that are not required by the user in the operable area 104, the number of interface detail screens 107 displayed in the operable area 104 can be reduced. As a result, the user can reduce the trouble of selecting a device to be operated from the interface detail screen 107 displayed in the operable area 104.
Further, by storing the contents once selected in the storage unit 40, it is possible to display only the necessary interface detail screen 107 without selecting again when the avatar 101 moves to the same position again.
In addition, the detailed screen display selection unit 34 displays the interface detail screens 107 one by one in the selection area 105 and displays images of different devices one after another at the same position each time selection is completed. Does not need to select a device to be selected with a mouse or the like.
Note that the detailed screen display selection unit 34 may display the interface detail screen 107 in the selection area 105 when a predetermined operation key is pressed when the user wants to select again.
In the above description, when the user performs an operation that is not selected, the interface detail screen 107 is hidden. However, instead of being hidden, the interface detail screen 107 is moved to the non-operational area 106 and displayed. It is also possible to display the images in a superimposed manner. In this case, referring to the interface detail screen 107 displayed in the non-operational area 106, the user can grasp what other devices are provided. Furthermore, it is good also as operation | movement which can perform selection operation in the operation impossible area 106. FIG. The user can display the interface detail screen 107 of the device in the operable area 104 by selecting again the device that is determined to be unnecessary once.

FIG. 7 is a diagram showing a processing flow of the display device according to the present embodiment.
The processing described in FIG. 6 will be described in detail using the processing flow of FIG.
As a premise, it is assumed that the avatar 101 moves in accordance with a user instruction and exists at a location 100 in the plant.
Then, as described in the flow of FIG. 4, the positional relationship calculation unit 31 acquires the position information of the avatar 101 and the position information of the devices from the memory, calculates these distances, and the distance to the avatar 101 is greater than the first threshold. Identify equipment in a small location. Then, the positional relationship calculation unit 31 outputs information indicating the identifiers of the specified devices to the detailed screen display selection unit 34. Next, the detailed screen display selection unit 34 reads the interface detailed screen from the storage unit 40 using the acquired identifier of the device, and displays the interface detailed screen on the selection area 105 (step S11). The order of overlapping may be, for example, in the order of identifiers, or may be displayed on the front side closer to the avatar 101.

Step S11 will be described in detail. In step S11, the detailed screen display selection unit 34 uses, for example, a table shown in FIG. In the “operable flag” column of this table, a value indicating that “display / do not display” or neither of them is set in the operation area for the device having the identifier is set. If the value in the “operable flag” field is “0”, it indicates that the device has not been set at all. A value of “1” indicates that “display in the operation area” is set for the device. A value of “2” indicates that the device is set to “not display in the operation area”.
In step S11, the detailed screen display selection unit 34 reads this table, selects devices whose “operation possible flag” value is “0”, and displays an interface image in the selection area only for those devices. .
For devices whose flag value is “1”, the detailed screen display selection unit 34 outputs the identifier information to the detailed screen display control unit 32, and the detailed screen display control unit 32 outputs the identifier information to the operable area. And Devices whose flag value is “2” are not displayed.
In the example of FIG. 8, the detailed screen display selection unit 34 displays the interface image of the device indicated by the TAG “A-101” in the selection area. The detailed screen display control unit 32 displays the image interface of the device indicated by the TAG “B-101” in the operable area. The interface image of the device indicated by the TAG “C-102” has already been set not to be displayed, so it is not displayed anywhere.

Next, the detail screen display selection unit 34 performs control so that the interface detail screen 107 displayed at the forefront becomes the target of the user's selection operation. Specifically, the detailed screen display selection unit 34 focuses on the interface image to make it active (step S12). Further, the detailed screen display selection unit 34 may display a red frame on the outer peripheral portion of the interface detail screen 107 so that the user can easily understand.
Next, the detailed screen display selection unit 34 detects a signal indicating the selection operation by the user from the operation unit 20 and determines whether or not the user has selected to display the interface image of the device i in the operable area ( Step S13).
When the detailed screen display selection unit 34 acquires a signal indicating that the device i is selected, the detailed screen display selection unit 34 outputs the identifier of the device i to the detailed screen display control unit 32. Next, the detailed screen display control unit 32 moves and displays the interface detailed screen 107 of the device i from the selection area 105 to the operable area 104 based on the acquired identifier (step S14). Then, the detailed screen display selection unit 34 records in the storage unit 40 that “display” is selected in the operable area 104 for the device i. For example, in the case of the example of FIG. 8, “1” is set in the “operation possible flag” column of the record having the TAG value indicating the device i.
When the detailed screen display selection unit 34 acquires a signal indicating that the device i is not selected, the detailed screen display selection unit 34 hides the interface image of the device i (step S15). Then, the detailed screen display selection unit 34 records in the storage unit 40 that “not display” is selected in the operable area for the device i. For example, in the case of the example of FIG. 8, “2” is set in the “operation possible flag” field of the record having the TAG value indicating the device i.

Next, the detailed screen display selection unit 34 determines whether or not the user has selected whether or not to display all the devices displayed in the selection area in step S11 (step S16). If selection has been completed for all the devices (step S16 = Yes), this processing flow ends. When that is not right (step S16 = No), the process from step S12 is repeated about the following interface detail screen 107. FIG.
Then, when processing is completed for all devices, this processing flow ends.

<Third embodiment>
The operation of the plant operation training apparatus according to the third embodiment of the present invention will be described below with reference to FIG.
The third embodiment is different from the second embodiment in that the user previously sets the type of device to be displayed in the selection area 105.
FIG. 9 is a diagram showing a setting screen of the plant operation training apparatus 1 according to the present embodiment.
FIG. 9 shows an example of a setting screen on which a user who acts as an instructor for plant operation training can set a device for displaying the interface detail screen 107 in the selection area 105.
Reference numeral 110 indicates a setting screen. Reference numeral 112 denotes a check box group that can set display / non-display in the selection area 105 for each device. The device “operator 1” corresponding to the check box 112a checked by the user is a device to be displayed in the selection area by the detailed screen display selection unit 34. The device “display 3” corresponding to the check box 112b not checked by the user is a device that the detailed screen display selection unit 34 does not display in the selection area.
Even if the “operator 1” is checked, the detailed screen display selection unit 34 may be configured to “operate” after the user has set whether or not to display the “operator 1” in the operable area 104. The interface detail screen 107 of “device 1” is not displayed in the selection area 105.

Reference numeral 108 denotes an OK button. When the user depresses the OK button 108 after checking the check box 112, the detailed screen selection setting unit 35 stores the content set by the user on this screen in the table shown in FIG. Then, the setting screen 110 is closed.
An example of the operation in which the detailed screen selection setting unit 35 stores the setting value in the table will be described using the table shown in FIG.
For devices newly checked by the user, values may be set as follows. Originally, when the value of the “operation possible flag” is “0” or “1” for the device, the value is maintained as it is. When the value is “2”, the detailed screen selection setting unit 35 sets “0”. If the value in the “operable flag” column is “2” originally, it means that the device has been set not to be displayed in the operable area. However, it is considered appropriate to check the “display” check box on the setting screen 110 for such a device again to give the user an opportunity to select whether or not to display in the operation selection area. Because.
Further, when the user removes the check from the device that has been checked up to now, the detailed screen selection setting unit 35 sets “2” in the “operation possible flag” field. By setting “2”, the interface image of the device is not displayed in the selection area or the operable area.

Numeral 109 indicates a cancel button. When the user presses the cancel button 109, the detailed screen selection setting unit 35 closes the setting screen 110 without updating the table in the storage unit 40.

By providing such setting means, it is possible to reduce the number of interface images to be displayed in the selection area, and save the user from having to perform driving training to select necessary equipment.
This function can be used, for example, to select a device to be displayed in accordance with the training content of a user who is trained by a driving training instructor. For example, when the level of a user who is trained is a beginner, it is desirable to display only the interface images of the minimum necessary devices, but this is possible by using the settings of this embodiment. This function can also limit the display of devices that are not normally used.
Note that this embodiment can be used in combination with the first embodiment. In that case, for example, control is performed as follows. The detailed screen display control unit 32 refers to the table in which the detailed screen selection setting unit 35 records whether or not to display for each device. When the distance from the avatar becomes smaller than the first threshold, “display” is set in this table. Only the image of the connected device is displayed. When combined with the first embodiment, an interface image of a necessary device can be displayed to a user who does not have knowledge of selecting the necessary device from the selection area.
As described above, according to the present embodiment, it is possible to obtain an effect that not only saves the user of the operation training from selecting the necessary equipment but also provides opportunities for operation training of the plant to various levels of users. Can do.

<Fourth embodiment>
The operation of the plant operation training apparatus according to the fourth embodiment of the present invention will be described below with reference to FIGS.
The fourth embodiment is different from the first to third embodiments in that the part provided with the device operated by the user is displayed by blinking.
FIG. 10 is a diagram showing an operation screen of the plant operation training apparatus 1 according to the present embodiment.
The operation in which the corresponding part display control unit 33 displays the part provided with the device corresponding to the interface image selected by the user in a manner different from other devices will be described with reference to FIG.
FIG. 10 is a 3D image showing that the interface detail screen 107 of the high-pressure water supply valve rear valve 103 is displayed in the operable area 104 when the avatar 101 moves to the location 100 in the plant by the user's operation. The high-pressure water supply valve rear valve 103 is provided within a distance smaller than the first threshold value with the avatar 101, and reference numeral 113 indicates a portion where the high-pressure water supply valve rear valve 103 is provided.

Here, when the user selects the interface detail screen 107 of the operable area 104 by the operation means 20, the corresponding part display control unit 33 displays a red frame on the outer peripheral portion of the interface detail screen 107. Then, the corresponding part display control unit 33 makes the part 113 provided with the high-pressure water supply valve rear valve 103 blink to make it easy for the user to see.
Moreover, when an avatar approaches a predetermined distance from a large equipment such as a turbine equipped with many instruments, the corresponding part display control unit 33 first displays the large equipment in a different color or the like. It may be displayed prominently. When the user selects a device in the operable area 104, the corresponding part display control unit 33 may blink and display the part provided with the device.
According to this embodiment, the user can know where the device to be operated is provided.
With such an operation, it is possible to learn the operation method while grasping the installation location of the equipment, so that it is possible to expect the same high training effect as when performing a practical training using an actual plant.

FIG. 11 is a diagram showing a processing flow of the display device according to the present embodiment.
The processing described in FIG. 10 will be described in detail using the processing flow in FIG.
As a premise, it is assumed that the avatar 101 moves in accordance with a user instruction and exists at a location 100 in the plant. Further, it is assumed that an interface detail screen 107 of devices within a distance range smaller than the first threshold is displayed in the operable area 104 with the avatar 101.
First, when the user operates the operation means 20, one is selected from the interface details screen 107 displayed in the operable area 104. Then, the corresponding part display control unit 33 activates the interface detail screen 107 and performs control to display a red frame on the outer peripheral portion (step S31).
Next, the corresponding part display control unit 33 blinks and displays the 3D image of the device corresponding to the selected interface detail screen 107. Specifically, the corresponding part display control unit 33 specifies a program for generating a 3D image of the device using the identifier of the device corresponding to the selected interface detail screen 107. Then, the corresponding part display control unit 33 instructs the specified program to change or blink the color of the part (step S32). For example, an RGB value indicating the changed color may be specified in a program for generating a 3D image, and the device may be blinked and the color may be changed. In addition, it is preferable to select a conspicuous color so that the color to be changed or blinked is easily noticeable by the user.
Next, the corresponding part display control unit 33 detects whether another interface display screen displayed in the operable area is selected by the user's selection operation (step S33). When another interface screen is selected, the processing from step S31 is repeated. In addition, for a non-selected device, an instruction is given to the program that generates a 3D image of the device to return to the original display mode.

<Fifth embodiment>
The operation of the plant operation training apparatus according to the fifth embodiment of the present invention will be described below with reference to FIGS. 12A to 13.
FIG. 12A is a first diagram showing parameter values displayed on the interface details screen of the plant operation training apparatus 1 according to the present embodiment. FIG. 12B is a second diagram showing parameter values displayed on the interface details screen of the plant operation training apparatus 1 according to the present embodiment. 12A and 12B, when the avatar 101 exists at the location 100, the storage unit 40 displays the list of devices provided at a distance closer to the avatar 101 than the first threshold and the interface details screen of each device. The parameter value which has is shown.
FIG. 12A shows the parameter value values of each device before the interface detail screen 107 of each device is displayed in the operable area. As shown in this figure, at this time, the storage unit 40 does not yet have a parameter value to be displayed on the interface of each device.
FIG. 12B shows parameter values of each device when the interface detail screen 107 of each device is displayed in the operable area. As shown in this figure, the storage unit 40 has each parameter value acquired from the plant simulation apparatus 2.

If all the parameter values are always acquired by communicating in the plant operation training apparatus 1, the processing capacity of the CPU of the plant operation training apparatus 1 is consumed for communication processing, and the calculation load increases. As a result, 3D image generation processing for driving training is affected, and the 3D image display cannot be displayed smoothly. According to the present embodiment, only necessary parameter values are extracted and communicated to reduce the communication load, thereby reducing the calculation load of the plant operation training apparatus 1 that displays the 3D virtual plant image. Thereby, the effect that 3D image display can be displayed smoothly is acquired.
Moreover, the plant operation training system which consists of the plant operation training apparatus 1 and the plant simulation apparatus 2 (and the training simulator apparatus of the central control room) is designed on the assumption that a plurality of users use it at the same time. For example, the user A trains the operation method of the device A using the plant operation training apparatus 1A, and at the same time, another user B trains the operation method of the device B using the plant operation training apparatus 1B. The plant operation training apparatuses 1A and 1B are both connected to the plant simulation apparatus 2 via a network. When the user A performs the operation A on the device A while the user B performs the operation B on the device B in parallel, the plant simulation apparatus 2 influences the operations A and B on the state of the plant. It calculates and transmits the result to the plant operation training apparatuses 1A and 1B. In this way, this system provides a function of operation training in which a single plant is operated at a plurality of locations at the same time.
In this way, when a plurality of users perform training, parameter values of all the devices included in the plant are communicated between each plant operation training device 1 and the plant simulation device 2 every time the state of the plant changes. It consumes the network bandwidth of the system. According to the present embodiment, the effect of reducing the network load of the entire system can be obtained by limiting the communication to the minimum necessary parameter value.

FIG. 13 is a first diagram illustrating a processing flow of the display device according to the present embodiment.
The processing described in FIGS. 12A and 12B will be described using the processing flow of FIG.
As a premise, it is assumed that the avatar 101 moves in accordance with a user instruction and exists at a location 100 in the plant. The processing flow is executed immediately before the detailed screen display control unit 32 displays the interface detailed screen of the devices within the distance range smaller than the first threshold value in the operable area 104 with the avatar 101. To do.
First, the detailed screen display control unit 32 acquires the identifier (TAG) of one device among the devices to be displayed on the interface detailed screen 107 in the operable area 104 in the same manner as step S4 in FIG. Is output to the parameter acquisition unit 36 (step S41). Next, the parameter acquisition unit 36 requests the latest parameter value for the TAG from the plant simulation device 2 via the communication unit 50 (step S42).
Here, it is assumed that the plant simulation apparatus 2 calculates the plant state quantity at each time and holds it for each TAG information. The plant simulation apparatus 2 transmits the latest parameter value in response to the request from the parameter acquisition unit 36.
The parameter acquisition unit 36 acquires the parameter value of the device corresponding to the TAG requested from the plant simulation device 2 via the communication unit 50 (step S43). The parameter acquisition unit 36 then outputs the acquired parameter value to the detailed screen display control unit 32. Next, the detailed screen display control unit 32 outputs the interface detailed screen 107 including the acquired parameter value to the operable area (step S44). The detailed screen display control unit 32 determines whether or not the above processing has been performed for all devices to be displayed in the operable area 104 (step S45), and repeats the processing from steps S41 to S44 for all devices.

The plant operation training apparatus 1 described above has a computer inside. Each process of the plant operation training apparatus 1 described above is stored in a computer-readable recording medium in the form of a program, and the above process is performed by the computer reading and executing this program. Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.

Further, the program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, what is called a difference file (difference program) may be sufficient.
