Description

  The present invention relates to a multi-deck elevator evacuation support apparatus that causes a multi-deck elevator installed in a building to perform an evacuation operation when a fire occurs in the building.

  Generally, when a fire breaks out in a building, an elevator car often stops as it is without returning automatically after stopping at the nearest floor. This is mainly to prevent secondary disasters caused by elevator operation. However, in recent buildings, technology related to fire prevention compartments etc. has improved, so even if a fire breaks out, it is often safe to continue elevator operation if the stop floor of the car is restricted .

Conventionally, an evacuation elevator for performing a rescue operation in which a car is moved between a fire occurrence floor and an evacuation floor at the time of a fire has been proposed (see, for example, Patent Document 1).
Also, conventionally, buildings are divided into high-rise zones, middle-rise zones, and low-rise zones, and evacuation operation is prohibited in zones that include fire floors, and rescues are made from the location of fire floors and each zone in other zones. An elevator that performs driving and evacuation driving has been proposed (see, for example, Patent Document 2).

JP-A-6-16357 JP 2007-39167 A

  However, in a multi-deck elevator (i.e., an elevator having a plurality of car rooms connected in the vertical direction), each car room is connected up and down, so that the floor affected by the fire (for example, the floor where the fire occurred, Even when a car room is stopped on a floor that is off the floor immediately above the fire-occurring floor, etc., another car room may stop on the floor affected by the fire.

  The present invention has been made in order to solve the above-described problems, and evacuation support for a multi-deck elevator capable of more reliably performing evacuation operation avoiding a fire prediction area including a fire occurrence floor. The object is to obtain a device.

  The evacuation support apparatus for a multi-deck elevator according to the present invention is a person who remains in a building when a fire occurs in a building provided with a multi-deck elevator having a plurality of cabs connected in the vertical direction. A multi-deck elevator evacuation support device that evacuates to an evacuation floor by using a multi-deck elevator, and based on information identifying the fire occurrence floor, an evacuation plan drafting means for drafting an evacuation plan using the multi-deck elevator, Based on information from the evacuation plan planning means, a stoppable floor that sets a stoppable floor for each cab that avoids the cabs from being shut down simultaneously inside and outside the fire prediction area including the fire occurrence floor Based on the setting means and the evacuation plan, avoid the fire prediction area and move the connected car including each cab between the stoppable floor and the evacuation floor. And a control command means outputs a command of performing the operation to the elevator controller.

  In the multi-deck elevator evacuation support apparatus according to the present invention, a stoppable floor of each cab is set so as to avoid being simultaneously stopped inside and outside the fire prediction area. The room can be prevented from being stopped in the fire prediction area, and the evacuation operation avoiding the fire prediction area can be more reliably performed.

Embodiment 1 FIG.
1 is a block diagram showing an evacuation support apparatus for a double deck elevator according to Embodiment 1 of the present invention. FIG. 2 is a conceptual diagram for explaining the evacuation operation of the double deck elevator performed by the evacuation support apparatus of FIG. In the figure, a double deck elevator 1 is provided in the building. The double deck elevator 1 has a plurality (two in this example) of elevators (No. 1 and No. 2).

  Each elevator has an elevator control device 2 that controls the operation of the elevator, and a connecting car 3 that is moved under the control of the elevator control device 2. The connecting car 3 has an upper car room 4 and a lower car room 5 (FIG. 2) connected in the vertical direction.

  In this example, the building has a basement floor (B1 floor) and 1 to 10 floors. The building is provided with stairs (not shown) for moving between the floors. Further, a push-down floor capable of stopping the lower cab 5 is provided below the basement floor. Furthermore, the entrance floor of the building is the first floor. In addition, the entrance floor of the building and the floor directly below (the first floor and the basement floor) are evacuated floors in the event of a fire.

  In the elevator control device 2, stoppable floors during normal operation (before a fire) are set for the upper cab 4 and the lower cab 5, respectively. In this example, as shown in FIG. 2, the basement floor and the even floor are set as the stoppable floors of the upper cab 4, and the push-down floor and the odd floor are set as the stoppable floors of the lower cab 5. Therefore, during the normal operation of the double deck elevator 1, the upper cab 4 does not stop on the odd floor and the lower cab 5 does not stop on the even floor.

  Fire detectors 6 are provided in the rooms, passages, elevator halls and the like on each floor. Information from each fire detector 6 is sent to the evacuation support apparatus 7 as information for identifying the fire occurrence floor. The evacuation support device 7 manages the operation of the double deck elevator 1 in the event of a fire based on information from each fire detector 6. In addition, the evacuation assistance apparatus 7 is provided in the management room (disaster prevention center) etc. which were installed in the basement floor, for example.

  The evacuation support apparatus 7 includes communication means 8, evacuation plan planning means 9, stoppable floor setting means 10, and control command means 11.

  The communication means 8 performs information communication between each fire detector 6 and each elevator control device 2 and the evacuation support device 7.

  The evacuation plan planning means 9 formulates an evacuation plan using the double deck elevator 1 based on information from each fire detector 6. In this example, the evacuation plan planning means 9 sets the fire occurrence floor and the floor immediately above the fire occurrence floor as a fire area (fire prediction area), and performs an evacuation operation for each elevator unit while avoiding the fire prediction area. To plan.

  Based on the information from the evacuation planning means 9, the stoppable floor setting means 10 divides each car room (upper car room 4 and lower car room 5) of the connected car 3 into and out of the fire prediction area and is simultaneously stopped. The floors that can be stopped are set for each of the upper cab 4 and the lower cab 5.

  Based on the information of the evacuation plan prepared by the evacuation plan planning means 9 and the information from the stoppable floor setting means 10, the control instruction means 11 avoids the fire prediction area and the evacuation floor (the first floor). And an evacuation operation command (evacuation operation command) for moving the connected car 3 to and from the basement floor). The evacuation operation command is sent from the control command means 11 to the elevator control device 2 via the communication means 8.

  The evacuation support apparatus 7 is composed of a computer having an arithmetic processing unit (CPU), a storage unit (ROM, RAM, etc.) and a signal input / output unit. The functions of the communication means 8, the evacuation plan planning means 9, the stoppable floor setting means 10 and the control command means 11 are realized by a computer of the evacuation support apparatus 7.

  That is, a program for realizing the functions of the communication means 8, the evacuation plan planning means 9, the stoppable floor setting means 10 and the control command means 11 is stored in the storage unit of the computer. The arithmetic processing unit executes arithmetic processing related to the function of the evacuation support apparatus 7 based on the program stored in the storage unit.

  The elevator control device 2 performs an evacuation operation for the double deck elevator 1 by receiving an evacuation operation command from the control command means 11. The evacuation operation is performed by moving the connecting car 3 between the stoppable floor set by the stoppable floor setting means 10 and the evacuation floor while avoiding the fire prediction area. Accordingly, the connected car 3 during the evacuation operation is not stopped in the fire prediction area.

  Next, the operation will be described. FIG. 3 is a flowchart for explaining the operation of the evacuation support apparatus 7 of FIG. The evacuation support apparatus 7 constantly receives information from each fire detector 6 (S101), and always determines whether or not a fire has occurred based on the received information (S102). When it is determined that no fire has occurred, the evacuation support apparatus 7 repeatedly determines whether a fire has occurred.

  When it is determined that a fire has occurred, the evacuation support device 7 identifies the fire occurrence floor based on the information from the fire detector 6 (S103). The fire occurrence floor is specified by setting the floor where the fire detector 6 that detects the occurrence of the fire is installed as the fire occurrence floor. In this example, a fire occurs on the fourth floor of the building, and the fourth floor is identified as the fire occurrence floor.

  After that, the fire occurrence floor (4th floor) and the floor immediately above the fire occurrence floor (5th floor) were designated as fire prediction areas by the evacuation planning means 9, and the fire prediction areas (4th floor and 5th floor) were avoided. An evacuation plan for evacuation operation is drawn up. In the evacuation plan, fire prediction areas (4th floor and 5th floor) are targeted from the service floors of the upper car room 4 and the lower car room 5 (floor where the car room is stopped to get passengers on and off the landing). Floor) is excluded (S104).

  Thereafter, the evacuation support device 7 takes in information on the floors that can be stopped during normal operation for each of the upper cab 4 and the lower cab 5 from the elevator control device 2 (S105).

  Thereafter, the evacuation support device 7 determines that the information on the floor that can be stopped during normal operation taken from the elevator control device 2 is the fire prediction area of each cab of the connected cab 3 (upper cab 4 and lower cab 5). It is determined whether or not the information is information that can be stopped at the same time (S106).

  If it is determined that each car room is to be stopped inside and outside the fire prediction area, each stoppable floor of the upper car room 4 and the lower car room 5 is the stop set by the stoppable floor setting means 10 The floor is changed to a possible floor (S107).

  In this example, during normal operation (before the fire), when the upper cab 4 is stopped on the sixth floor, the lower cab 5 is stopped on the fifth floor in the fire prediction area, and the lower cab 5 is on the third floor. Control is performed so that the upper cab 4 is stopped on the fourth floor in the fire prediction area when the vehicle is stopped. Therefore, the upper car room 4 and the lower car room 5 may be divided and stopped inside and outside the fire prediction area. From this, the stoppable floors of the upper car room 4 and the lower car room 5 are changed to the stoppable floors (stoppable floors after the fire) set by the stoppable floor setting means 10. As a result, the floor where the upper car room 4 and the lower car room 5 can stop is shifted by one floor from the floor where the upper car room 4 and the lower car room 5 can stop during normal operation (before fire). It is avoided to be divided and stopped inside.

  If it is determined that each car room is not divided into the fire prediction area and is not stopped at the same time, the setting of the stopable floors of the upper car room 4 and the lower car room 5 is maintained and changed as it is. There is nothing.

  Thereafter, the evacuation support apparatus 7 acquires information on a cab room whose top floor is a stoppable floor and information on a cab room whose bottom floor is a stoppable floor (S108), and based on the acquired information It is determined whether or not the identified cab can reach the top floor or the bottom floor (S109).

  In this example, the 10th floor which is the top floor is set as a stoppable floor of the lower cab 5 after the fire as shown in FIG. In this case, there is no push-up floor above the top floor where the upper cab 4 can be stopped. Accordingly, the lower cab 5 cannot reach the 10th floor (top floor). The basement floor, which is the lowest floor, is set as a stoppable floor of the lower cab 5 after the fire. Since the stop floor of the upper cab 4 is set immediately above the basement, the lower cab 5 can reach the basement.

  If there is a floor in which the cab is not reachable among the top floor and the bottom floor, the evacuation support apparatus 7 excludes the floor from the service floor of the cab (S110). Further, if neither the top floor nor the bottom floor corresponds to a floor that the cab cannot reach, the evacuation support device 7 excludes the top floor and the bottom floor from the service floor of the cab room. do not do. In this example, the 10th floor, which is the top floor, is excluded from the service floor.

  Thereafter, the evacuation support apparatus 7 performs an evacuation operation command for performing an evacuation operation avoiding the floors (in this example, the fourth floor, the fifth floor, and the tenth floor) excluded from the service floor of the cab by the above processing. Is output from the control command means 11 to the elevator control device 2. Upon receiving the evacuation operation command, the elevator control device 2 starts the evacuation operation based on the evacuation operation command for the double deck elevator 1 (S111).

  In such an evacuation support apparatus 7 for a double deck elevator, a stoppable floor for each cab is set so as to prevent the upper cab 4 and the lower cab 5 from being simultaneously stopped by dividing the fire prediction area. Therefore, it is possible to prevent some of the cabs from being stopped in the fire prediction area during the evacuation operation, and it is possible to more reliably perform the evacuation operation while avoiding the fire prediction area.

Embodiment 2. FIG.
FIG. 4 is a block diagram showing an evacuation support apparatus for a double deck elevator according to Embodiment 2 of the present invention. FIG. 5 is a conceptual diagram for explaining the evacuation operation of the double deck elevator performed by the evacuation support apparatus of FIG. In the figure, the evacuation support apparatus 7 includes communication means 8, evacuation plan planning means 9, stoppable floor setting means 10, rescue floor setting means 21, and control command means 11. The functions of the communication means 8, the evacuation plan planning means 9, the stoppable floor setting means 10 and the control command means 11 are the same as those in the first embodiment.

  The rescue floor setting means 21 is based on the information from the evacuation plan planning means 9 and the stoppable floor setting means 10 and generates a plurality of stoppages that are generated by dividing a predetermined number of stoppable floors by avoiding the fire prediction area and the evacuation floor. The zones are set as evacuation zones, and predetermined stoppable floors adjacent to each other in each evacuation zone are set as rescue floors. That is, the rescue floor setting means 21 divides the entire building into a plurality of evacuation zones including a predetermined number of stoppable floors while avoiding the evacuation floor and the fire prediction area based on the information of the fire prediction area and the stoppable floor. A predetermined rescue floor is set for each evacuation zone.

  The allowable number of stoppable floors included in the evacuation zone is determined according to the number of elevator units and the total number of floors in the building. In the evacuation support device 7, the relationship between the allowable number of floors that can be stopped in the evacuation zone, the number of elevators, and the total number of floors of the building is set in advance as a zone floor number determination criterion.

  FIG. 6 is a table showing an example of zone floor number determination criteria set in the evacuation support apparatus 7 of FIG. The allowable number of floors that can be stopped in the evacuation zone is determined by obtaining the number corresponding to the number of elevators and the total number of floors of the building while referring to the criteria for determining the number of floors in the zone. In this example, since there are two elevators and the number of floors of the building is 11 floors, the allowable number of stoppable floors in the evacuation zone is 6 floors. Therefore, as shown in FIG. 5, a first evacuation zone including the second floor and the third floor and a second evacuation zone including the sixth floor to the tenth floor are respectively set above and below the fire prediction area.

  The rescue floor is a set of stoppable floors (two stoppable floors where the upper cab 4 and the lower cab 5 are stopped simultaneously) set at the center of each evacuation zone or near the center. . In this example, in the first evacuation zone, the second and third floors are rescue floors, and in the second evacuation zone, the eighth and ninth floors are rescue floors.

  The control command means 11 outputs to the elevator control device 2 an evacuation operation command for performing an evacuation operation for moving the connected car 3 only between the rescue floor and the evacuation floor. The elevator control device 2 performs an evacuation operation for the double deck elevator 1 by receiving an evacuation operation command from the control command means 11. The evacuation operation is performed by moving the connected car 3 only between the rescue floor set by the rescue floor setting means 21 and the evacuation floor. Other configurations are the same as those in the first embodiment.

  Next, the operation will be described. FIG. 7 is a flowchart for explaining the operation of the evacuation support apparatus 7 of FIG. The operations (S101 to S106) up to determining whether each cab is divided into the inside and outside of the fire prediction area and stopped are the same as in the first embodiment. When it is determined that each car room is divided into the fire prediction area and stopped, the stoppable floors of the upper car room 4 and the lower car room 5 are set by the stoppable floor setting means 10. If the floor is changed to a possible floor (S107) and it is determined that each car room is not divided into the fire prediction area and stopped at the same time, the floors where the upper car room 4 and the lower car room 5 can be stopped are set. Is maintained as is.

  Thereafter, the rescue floor setting means 21 divides the entire building into two sections with the fire prediction area as a boundary (S201). Therefore, the fire prediction area is not included in each section. At this time, the evacuation floor is excluded from the section located under the fire prediction area. In this example, the section located above the fire prediction area includes the sixth floor to the tenth floor, and the section located below the fire prediction area includes the second floor and the third floor.

  Thereafter, the rescue floor setting means 21 determines the allowable number of stoppable floors in the evacuation zone while referring to the zone floor number determination criterion (FIG. 6). After that, the rescue floor setting means 21 divides the stoppable floors in the two sections divided by the fire prediction area as a boundary for each determined allowable number, and sets a plurality of zones generated thereby as evacuation zones. Set (S202). In addition, when the endmost floor in each section deviates from the evacuation zone, it is processed so as to be included in the evacuation zone adjacent to the endmost floor.

  In this example, since the allowable number of floors that can be stopped in the evacuation zone is the 6th floor, the two sections divided with the fire prediction area as a boundary become the first and second evacuation zones as they are.

  Thereafter, the rescue floor setting means 21 sets a set of stoppable floors near or in the center of each evacuation zone as a rescue floor (S203). In this example, the second and third floors are set as rescue floors for the first evacuation zone, and the eighth and ninth floors are set as rescue floors for the second evacuation zone.

  Thereafter, the evacuation support apparatus 7 excludes the floor of the building excluding the rescue floor and the evacuation floor from the service floor (S204). In this example, the floors excluded from the service floor are the 4th floor to the 7th floor and the 10th floor.

  Thereafter, the evacuation support device 7 outputs an evacuation operation command for performing an evacuation operation for moving the connected car 3 only between the rescue floor and the evacuation floor from the control command means 11 to the elevator control device 2. Upon receiving the evacuation operation command, the elevator control device 2 starts the evacuation operation based on the evacuation operation command for the double deck elevator 1 (S205).

  When the evacuation operation of the double deck elevator 1 is performed, the people present on the floor other than the rescue floor move to the rescue floor on the stairs.

  In such an evacuation support device 7 for a double deck elevator, after a plurality of zones generated by dividing a predetermined number of stoppable floors together to avoid a fire prediction area are defined as evacuation zones, they are adjacent to each other in each evacuation zone. The predetermined stoppable floor is set as the rescue floor, and the evacuation operation for moving the connected car 3 only between the rescue floor and the evacuation floor is performed for the double deck elevator 1, so the number of stops of the connected car 3 is reduced. It is possible to improve the transportation efficiency of the residents. In addition, since the residents gather on the rescue floor, it is possible to improve the boarding ratio of the residents in the connected car 3.

Embodiment 3 FIG.
FIG. 8 is a block diagram showing an evacuation support apparatus for a double deck elevator according to Embodiment 3 of the present invention. FIG. 9 is a conceptual diagram for explaining the evacuation operation of the double deck elevator performed by the evacuation support apparatus of FIG. In the figure, a resident information acquisition device 32 capable of acquiring information specifying the number of people in each floor is installed in the building. Examples of the resident information acquisition device 32 include a card reader installed on the entrance floor and a monitoring camera installed on each floor.

  Information from each fire detector 6 and the resident information acquisition device 32 is sent to the evacuation support device 7. The evacuation support device 7 manages the operation of the double deck elevator 1 at the time of a fire based on information from each of the fire detectors 6 and the resident information acquisition device 32.

  The evacuation support apparatus 7 includes communication means 8, evacuation plan planning means 9, stoppable floor setting means 10, rescue floor setting means 31, and control command means 11. The functions of the communication means 8, the evacuation plan planning means 9, the stoppable floor setting means 10 and the control command means 11 are the same as those in the first embodiment.

  The rescue floor setting means 31 receives information on the fire prediction area, the floor that can be stopped, and the number of people in the building from the evacuation plan planning means 9, the floor that can be stopped 10 and the person information acquisition device 32, respectively. Further, the rescue floor setting means 31 is a rescue floor for identifying the rescue floor on which the connected car 3 is dispatched (stopped) during the evacuation operation based on each information of the fire prediction area, the floor that can be stopped, and the number of people in the building. Determination data is calculated. The rescue floor determination data is data indicating the relationship between each stoppable floor excluding the fire prediction area and the evacuation floor and the number of people in the building. The rescue floor is set avoiding the fire prediction area and the evacuation floor.

  Based on the rescue floor determination data, the rescue floor setting means 31 collectively divides a plurality of stoppable floors whose total number of people in the building satisfies a predetermined standard, and sets the resulting zones as evacuation zones, For the zone, the stoppable floors adjacent to each other specified according to the distribution of the number of people in each stoppable floor are set as rescue floors. The predetermined standard is determined in advance by the maximum number of passengers in the connected car 3 and the number of elevator cars. When the total number of people in the evacuation zone is within a range that does not exceed a predetermined allowable value, the predetermined standard is satisfied.

  FIG. 10 is a table showing an example of rescue floor determination data calculated by the rescue floor setting means 31 of FIG. In this example, each stopable floor (2nd floor, 3rd floor, 6th floor to 10th floor) except the 4th floor and 5th floor that are fire prediction areas and the basement floor and 1st floor that are evacuation floors The relationship with the number of persons is calculated as rescue floor determination data. In addition, a predetermined allowable value for limiting the total number of people in the evacuation zone is preset as 1000 people.

  In the example shown in FIG. 10, since the total number of people in the building does not reach a predetermined allowable value (1000 people) in any of the sections divided above and below the fire prediction area from the rescue floor determination data, The second and third floors are designated as the first evacuation zone, and the sixth to tenth floors are designated as the second evacuation zone.

  The rescue floor is identified by adding the number of people in the building in order from the lowest floor in the evacuation zone, and the cumulative value of the number of people in the evacuation zone first becomes 1/2 of the total number of people in the evacuation zone. The floor that can be stopped when it is reached, the floor that is adjacent to the floor that can be stopped, and the floor that can be stopped at the same time that the connected car 3 is stopped (a set of floors that can be stopped) is the rescue floor. Is called.

  In the example shown in FIG. 10, for the first evacuation zone, the second and third floors are used as rescue floors, and for the second evacuation zone, the eighth and ninth floors are used as rescue floors.

  The control command means 11 outputs to the elevator control device 2 an evacuation operation command for performing an evacuation operation for moving the connected car 3 only between the rescue floor and the evacuation floor. The elevator control device 2 performs an evacuation operation for the double deck elevator 1 by receiving an evacuation operation command from the control command means 11. The evacuation operation is performed by moving the connected car 3 only between the rescue floor set by the rescue floor setting means 21 and the evacuation floor. Other configurations are the same as those in the first embodiment.

  Next, the operation will be described. FIG. 11 is a flowchart for explaining the operation of the evacuation support apparatus 7 of FIG. The operations (S101 to S106) up to determining whether each cab is divided into the inside and outside of the fire prediction area and stopped are the same as in the first embodiment. When it is determined that each car room is divided into the fire prediction area and stopped, the stoppable floors of the upper car room 4 and the lower car room 5 are set by the stoppable floor setting means 10. When the floor is changed to a possible floor (S107) and it is determined that each car room is not divided into the inside and outside of the fire prediction area and stopped at the same time, the stopable floors of the upper car room 4 and the lower car room 5 are set. Is maintained as is.

  Thereafter, the rescue floor setting means 21 divides the entire building into two sections with the fire prediction area as a boundary (S301). Therefore, the fire prediction area is not included in each section. At this time, the evacuation floor is excluded from the section located under the fire prediction area. In this example, the section located above the fire prediction area includes the sixth floor to the tenth floor, and the section located below the fire prediction area includes the second floor and the third floor.

  Thereafter, the rescue floor setting means 31 creates rescue floor determination data (FIG. 10) based on each information of the fire prediction area, the stoppable floor, and the number of people in the building (S302).

  Thereafter, the rescue floor setting means 31 divides a plurality of stoppable floors in which the total number of people in the building satisfies a predetermined standard based on the rescue floor determination data, and divides the resulting zones as evacuation zones. (S303).

  In this example, the total number of people in the section located below the fire prediction area is 300 people, and the total number of people in the section located above the fire prediction area is 700 people. The value (1000 people) is not exceeded, and each section satisfies a predetermined standard. Therefore, the section located below the fire prediction area is directly used as the first evacuation zone, and the section located above the fire prediction area is used as the second evacuation zone.

  Thereafter, the rescue floor setting means 31 sets a rescue floor for each evacuation zone. The rescue floor is set in order upward from the lowest evacuation zone. In this example, the rescue floor is set in the order of the first evacuation zone and the second evacuation zone.

  That is, the rescue floor setting means 31 first sets the first evacuation zone (second floor and third floor), which is the lowest evacuation zone, as a rescue floor setting target zone (S304). Thereafter, the rescue floor setting means 31 sets the cumulative value α of the number of people in the building to 0 (S305), and sets the lowest floor (second floor) in the setting target zone (first evacuation zone) as the cumulative target floor. (S306).

  Thereafter, the rescue floor setting means 31 adds the number of people on the accumulation target floor to the accumulation value α to obtain a new accumulation value α (S307).

  Thereafter, the rescue floor setting means 31 determines whether or not the new cumulative value α is smaller than ½ of the total number M of people in the setting target zone (S308).

  If the cumulative value α is smaller than ½ of the total number M of people in the setting target zone, after setting the cumulative target floor to a stoppable floor one level higher in the setting target zone (S309), The number of people on the floor to be accumulated is added to the accumulated value α to obtain a new accumulated value α (S307). Thereafter, the above operation (S307 to S309) is repeated until the cumulative value α is equal to or greater than ½ of the total number M of people in the setting target zone.

  If the cumulative value α becomes 1/2 or more of the total number M of people in the setting zone, the floor that can be stopped at that time and one of the cabs is the target of accumulation. An adjacent stoppable floor where the other cab is stopped when stopped on the floor is set as a rescue floor (S310).

  In this example, when the setting target zone is the first evacuation zone (the second floor and the third floor), as shown in FIG. 10, first, the second floor, which is the lowest floor in the first evacuation zone, is the cumulative target floor. It is said. The number of people on the second floor is already 200 people, which is more than half of the total number of people in the first evacuation zone (300 people). The third floor adjacent to is the rescue floor.

  When the setting target zone is the second evacuation zone (6th floor to 10th floor), the 6th floor, which is the lowest floor in the second evacuation zone, is set as the cumulative target floor. Thereafter, the number of people in the building is added in the order of the 6th floor and the 7th floor, and when the number of people in the 8th floor is added, the cumulative value α is the total number of people in the second evacuation zone (700 400 people, more than half of the number of people. Therefore, in this case, the 8th floor, which is the accumulation target floor, and the 9th floor adjacent to the 8th floor are the rescue floors.

  Thereafter, the rescue floor setting means 31 determines whether or not the rescue floor has been set for all the evacuation zones (S311). If not completed, the setting target zone is set to the evacuation zone one level higher (S312), and the above operation is performed for the new setting target zone (S305 to S310).

  When the setting of the rescue floors for all the evacuation zones is completed, the evacuation support apparatus 7 excludes the floors of the building excluding the rescue floor and the evacuation floor from the service floor targets (S313). In this example, the floors excluded from the service floor targets are the 4th to 7th floors and the 10th floor.

  Thereafter, the evacuation support device 7 outputs an evacuation operation command for performing an evacuation operation for moving the connected car 3 only between the rescue floor and the evacuation floor from the control command means 11 to the elevator control device 2. Upon receiving the evacuation operation command, the elevator control device 2 starts the evacuation operation based on the evacuation operation command for the double deck elevator 1 (S314).

  When the evacuation operation of the double deck elevator 1 is performed, the people present on the floor other than the rescue floor move to the rescue floor on the stairs.

  In such an evacuation support apparatus 7 for a double deck elevator, a plurality of stoppable floors whose total number of people satisfy a predetermined standard are collected based on information for specifying the number of people in each stoppable floor. After each of the resulting zones is designated as an evacuation zone, the adjacent stoppable floors identified according to the distribution of the number of people in each stoppable floor for each evacuation zone are rescue floors.
