Description

Door and window control system, method and computer-readable medium for fire mitigation

The present invention relates to a door and window control technology that slows down fire, and in particular, to a system and method that can automatically close doors and windows in a building when a fire occurs, so as to prevent the spread of the fire and increase the chances of people in the building being rescued.

According to statistics from the Fire Protection Department of the Ministry of the Interior of the Republic of China, there were a total of 20,687 fire accidents from January to November 2009, including 581 casualties. Fire accidents cause heavy casualties and property losses to Chinese people every year. Due to the rapid diffusion of thick smoke during a fire, it can rise 5 to 6 meters per second, and the temperature of the thick smoke may be as high as 200 to 600 degrees. Once a fire occurs, the fire or thick smoke will spread rapidly. Without prior drills or planning, it is easy to panic and escape, and even cause unnecessary deaths and injuries.

Although many high-rise buildings are currently required to install fire sprinkler systems on high floors to automatically trigger the indoor sprinkler system when a fire breaks out. In addition to quickly suppressing the fire, it can also make up for the inability of fire ladder trucks to rise to high floors for rescue operations. restrictions. However, for other buildings that are not required to install fire sprinkler systems, the fire risk is easily underestimated.

There is currently a technology that deploys multiple motion sensors in a building to detect whether there are people waiting to be rescued in a certain room on a certain floor, thereby determining the priority of firefighters for rescue. However, people in the fire scene tend to panic and escape, which leads to problems such as firefighters arriving at the scene but not being able to find the rescuers, or the rescuers hiding in rooms that are difficult to rescue, which greatly reduces the chance of successful rescue.

Another method used to reduce fire damage is to open doors and windows in conjunction with a fire, hoping to allow the air inside and outside the building to circulate or to eliminate the smoke generated by the fire. However, if this method is not matched with the smoke exhaust equipment in the building, opening the doors and windows rashly during a fire will result in the continuous injection of fresh air from outside, expanding the fire or the rapid spread of thick smoke. At present, many large factories are equipped with smoke exhaust equipment. When a fire occurs, the principle of pressure difference (from high pressure to low pressure) is used to force the smoke out of the building to reduce the chance of people in the house being choked by the smoke. However, ordinary residences rarely Install less smoke exhaust equipment.

Another existing technology provides a mechanism for linking opening and closing of windows, thereby achieving the functions of remote control and linkage control. Although this technology has effectively improved the convenience of controlling windows, it still cannot effectively reduce casualties when a fire occurs. This is because when a fire occurs, many people fall into coma due to inhaling toxic and high-temperature smoke, and are later burned or even burned by the fire. die. Therefore, if the spread of thick smoke cannot be effectively blocked when a fire occurs, it will be difficult to reduce the losses, deaths and injuries caused by the fire.

It can be seen that the above-mentioned conventional methods still have many shortcomings, are not good designs, and need to be improved urgently.

In order to solve the problems of the prior art, the present invention provides a door and window control system for slowing down the fire. The door and window control system is installed in the building and includes sensors, electric door bows, electric window openers and door and window control platforms. The sensor is used to detect whether there is a fire alarm event; the electric door bow is installed on the door of the building to detect the opening and closing status of the door and open or close the door; the electric window opener is installed on the door of the building. The windows of the building are used to detect the opening and closing status of the windows and open or close the windows; the door and window control platform is used to determine whether there is a fire alarm event based on the detection results of the sensors. When the fire alarm is lifted, the electric door opener is required to close the door, and the electric window opener is required to close the window, but the door or window is allowed to be opened or closed manually.

In one embodiment, the sensor includes a smoke detection sensor and a temperature sensor, and the door and window control platform is configured when the detection result of the smoke detection sensor is that the smoke concentration exceeds the standard and/or the temperature sensing When the detection result of the device is that the temperature exceeds the standard, it is judged that there is a fire alarm event.

In one embodiment, the electric door bow includes an infrared transmitter and an infrared receiver installed at different positions on the door frame of the door. The infrared receiver is used to receive the infrared rays emitted by the infrared transmitter. When the infrared rays are emitted, When the infrared transmitter and the infrared receiver are blocked during the process of closing the door by the electric door bow, the electric door bow will stop closing the door and open the door.

In one embodiment, the electric window opener includes an infrared transmitter and an infrared receiver installed at different positions on the window frame of the window. The infrared receiver is used to receive the infrared rays emitted by the infrared transmitter. When the infrared rays are emitted, When the infrared transmitter and the infrared receiver are blocked during the process of closing the window by the electric window opener, the electric window opener stops closing the window and opens the window.

In one embodiment, the door and window control platform periodically queries the electric door bow and the electric window opener for the opening and closing status of the door and the window during this period. If the electric door bow If the door is reported to be open, the door and window control platform will cause the electric door bow to close the door. If the electric window opener reports that the window is open, the door and window control platform will cause the electric window opener to close. The window.

In one embodiment, the door and the window belong to the same room of the building. If the electric door bow reports that the door is closed and the electric window opener reports that the window is open, the door and window control platform stops querying the opening and closing status of the window and stops causing the electric window opener to close the window. windows.

In one embodiment, the door and window control system further includes an alarm, wherein the door and window control platform is multiplexed to cause the alarm to sound an alarm and publish the detection results and connection status of the sensor, the electric The connection status of the door bow and the opening and closing status of the door, and the connection status of the electric window opener and the opening and closing status of the window.

In one embodiment, the door and window control platform is multiplexed to clear the fire alarm event according to the detection result of the sensor or according to the user's instruction.

The present invention also provides a door and window control method for reducing fire intensity. The door and window control method is used in buildings, including: detecting whether there is a fire alarm event; detecting the opening and closing status of doors and windows in the building except the main door; during the period from detecting the fire alarm event until the fire alarm event is resolved , close the door and window, but allow manual opening or closing of the door or window.

The present invention also provides a computer-readable medium, which can be used in a computing device, computer or server, and stores instructions to execute the above-mentioned door and window control method for reducing fire intensity.

The door and window control platform 2 is a server or computer with networking capabilities. The networking device 7 is a device that can be connected to the door and window control platform 2 through wired network or wireless network communication, such as a smartphone, computer or smart device. The above are only examples of the present invention, and do not limit the software or hardware specifications of the door and window control platform 2, sensor 3, electric door bow 4, electric window opener 5, alarm 6, and networking device 7.

Sensors 3 are deployed in a building according to the different uses of each space, such as smoke detection sensors and/or temperature sensors. Among them, the smoke detection sensors are deployed in areas where thick smoke is not likely to be generated in normal times. (such as non-cooking spaces), and the smoke detection sensor can be divided into ion type or photoelectric type according to different operating principles. Among them, the ion type smoke detection sensor uses ionization current to be affected by smoke. The principle of change is to detect whether the smoke concentration in the space exceeds the standard, and the photoelectric smoke detector uses the principle of photoelectric beam changes due to the influence of smoke to detect whether the smoke concentration in the space exceeds the standard, and the smoke that exceeds the standard The concentration is based on the approval standards for residential fire alarms announced by the Ministry of Interior of the Republic of China. If the smoke concentration in the space exceeds the standard, the smoke detection sensor will actively report a fire alarm event. Otherwise, the detection result of the smoke detection sensor will be no fire alarm event. another On the one hand, the temperature sensor detects whether the temperature of the space exceeds the standard. The excessive temperature is based on the approval standards for residential fire alarms announced by the Ministry of the Interior of the Republic of China. If the temperature of the space exceeds the standard, the temperature sensor will actively report a fire alarm event. Otherwise, the detection result of the temperature sensor will be no fire alarm event.

In addition, the sensor 3 can use a wireless communication protocol (such as ZigBee or Wireless High Fidelity Protocol (WiFi)) to transmit the detection result to the detection module 21 of the door and window control platform 2, and the sensor 3 is Power is supplied by an AC/DC automatic switching device, that is, the battery of the sensor 3 is charged with a common power source (such as commercial power) at ordinary times, and switches to the battery for power supply after a power outage. When the battery voltage is low, the light flashes or a sound is emitted to indicate that the power is about to be exhausted.

In one embodiment, each room door is equipped with a corresponding electric door bow 4 . The control module 42 of the electric door bow 4 includes a controller installed on the door frame of the door and a rotating arm or slide rail installed on the door according to the door opening method, wherein the rotating arm or The power of the slide rail can be provided by motor or pressurization. The controller is used to control the direction and speed of opening or closing of the rotating arm or the slide rail according to the opening command or closing command transmitted by the door and window control platform 2, thereby opening or closing the door. The detection module 41 of the electric door bow 4 includes an infrared transmitter and an infrared receiver installed at different positions on the door frame of the room. For example, the infrared transmitter and the infrared receiver can be installed in the room respectively. The upper door frame and the lower door frame. The infrared receiver is used for receiving infrared rays emitted by the infrared transmitter. When the controller of the electric door bow 4 closes the door, a blocking event occurs between the infrared transmitter and the infrared receiver, indicating that someone may pass through the passage between the upper and lower door frames and block the infrared rays. When transmitting and receiving, the controller controls the rotating arm or the slide rail to stop closing the door and opening the door to avoid pinching people. The detection module 41 of the electric door bow 4 is reused to report the opening and closing status of the door corresponding to the electric door bow 4 according to the query command of the door and window control platform 2 .

In addition, each window of the building is equipped with a corresponding electric window opener 5 . The control module 52 of the electric window opener 5 includes a controller and a push rod or slide rail. The controller and push rod or slide rail are installed on the window frame of the window according to the window opening mode. The power of the push rod or slide rail can be provided by motor or pressure. The controller is used to control the direction and speed of opening or closing of the push rod or slide rail according to the opening command or closing command transmitted by the door and window control platform 2, thereby opening or closing the window. The detection module 51 of the electric window opener 5 includes an infrared transmitter and an infrared receiver installed at different positions on the window frame of the window. For example, the infrared transmitter and the infrared receiver can be installed on the window respectively. Upper and lower window frames. The infrared receiver is used for receiving infrared rays emitted by the infrared transmitter. When the controller of the electric window opener 5 is in the process of closing the window, a blocking event occurs between the infrared transmitter and the infrared receiver, indicating that someone may pass through the passage between the upper and lower window frames and block the infrared rays. When transmitting and receiving, the controller controls the push rod or the slide rail to stop closing the window and opening the window to avoid pinching people. The detection module 51 of the electric window opener 5 is reused to report the opening and closing status of the window corresponding to the electric window opener 5 according to the query command of the door and window control platform 2 .

The user uses the user interface 71 of the networking device 7 in advance and sets the electric door bow 4 installed on each door of the building and installed on each window of the building through the operating interface 25 of the door and window control platform 2 name of the electric window opener 5 on the door and window of the same room, and pair the electric door bow 4 and the electric window opener 5 on the door and window of the same room. On the other hand, the user can also set the notification information of the fire alarm event through the operation interface 25 , including the user's SMS, email or contact information of other communication software, and the operation interface 25 then stores the notification information in the database 23 .

The sensor 3, the electric door bow 4 and the electric window opener 5 in Figure 2 can be collectively referred to as fire prevention equipment. The detection module 21 of the door and window control platform 2 usually queries the detection results (whether or not) of the detection module 31 of each sensor 3 periodically at intervals of a time interval A (for example, ten minutes). Fire alarm event), the opening and closing status of the door detected by the detection module 41 of each electric door bow device 4, and the opening and closing status of the window detected by the detection module 51 of each electric window opener 5, To obtain the operating status of such fire protection equipment. The operating status includes the connection status and detection results of each sensor 3, as well as the connection status and detected opening and closing status of each electric door bow 4 and each electric window opener 5. If the detection module 21 cannot obtain the detection result or the opening and closing status reported by a certain fire protection device within a set number of times, the connection status of the fire protection device is updated to an offline state.

In addition, the detection module 21 transmits the operating status of the fire protection equipment to the push module 24 . In addition to updating the operation status of the fire protection equipment to the database 23, the push module 24 also publishes the operation status of the fire protection equipment to the operation interface 25 and the user interface 71 of the networking device 7 for use by the operation interface 25. The interface 71 displays the operating status of the fire protection equipment. The push module 24 can use a communication protocol consistent with the push mechanism, such as the Message Queueing Telemetry Transport (MQTT) protocol, to publish the operating status of the fire protection equipment. The operation interface 25 and the user interface 71 can obtain the operation status published by the push module 24 by complying with the communication protocol of the push mechanism and subscribing to the channel.

When a fire occurs, the detection module 21 of the door and window control platform 2 sends an alarm message to the push module 24 based on the fire alarm event actively reported by the detection module 31 of the sensor 3, and the push module 24 not only updates the The alarm message is sent to the database 23, and the alarm message is further posted to the operation interface 25 and the user interface 71 of the networking device 7. The operation interface 25 can be based on the notification information (such as SMS, Contact information via email or other communication software), and send the alert message to the user via text message, email, or other communication method.

In one embodiment, after receiving the fire alarm event from the sensor 3, the detection module 21 not only triggers each alarm 6 through the control module 22, but also triggers each alarm 6 according to the detection module 41 of the electric door bow 4. According to the opening and closing status detected by the detection module 51 of the electric window opener 5, the closing command is sent to the control module 42 of the electric door bow 4 in the open state and the control of the electric window opener 5. Module 52 to close the corresponding door and window. Among them, for the electric door bow 4 and the electric window opener 5 that have been paired in the database 23, if the opening and closing status reported by the detection module 41 of the electric door bow 4 is a closed state, and the electric window opener If the opening and closing status reported by the detection module 51 of 5 is an open status, the detection module 21 notifies the control module 22 to stop sending the closing command to the control module 52 of the electric window opener 5 . On the other hand, when the operation interface 25 receives the stop command from the user interface 71, the stop command is sent to the control module 42 of each electric door bow 4 and each electric window opener 5 through the control module 22. Control the module 52 and each alarm 6 to stop the electric door bows 4 and the electric window openers 5 from closing the corresponding doors and windows, and stop the alarms 6 from sounding alarms, and then update the fire protection The operating status of the equipment is sent to database 23.

In step S101, the detection module 31 of the sensor 3 will actively send the fire alarm event to the detection module 21 of the door and window control platform 2. After receiving the fire alarm event, the detection module 21 changes to a shorter time interval B (for example, five seconds) to periodically query the detection results of the detection module 31 of the sensor 3, thereby Reduce the probability of the detection module 31 of the sensor 3 falsely reporting a fire alarm. If the detection result is still a fire alarm event, the detection module 21 will send an alarm message to the push module 24, and the push module 24 will not only update The alarm message is sent to the database 23, and the alarm message is further posted to the operation interface 25 and the user interface 71 of the networked device 7. In addition, the detection module 21 also simultaneously notifies the control module 22 to trigger the alarm 6 so that the alarm 6 sounds an alarm. If the fire expands and the common power source is damaged, the sensor 3, the electric door bow 4 and the electric window opener 5 can still use the power of the battery to continue to operate until the fire protection equipment is damaged by the fire or the battery power is exhausted.

In one embodiment, in order to reduce the situation where the sensor 3 falsely reports a fire alarm, multiple sensors 3 with different functions (such as smoke detection sensors) can be installed in important spaces of the building or in spaces according to different uses. detector and temperature sensor), and then the detection module 21 comprehensively determines whether it is a fire alarm event based on the detection results of these sensors with different functions. For example, if many users often gather in a confined space to smoke at the same time, the smoke concentration in the space will often be higher than that of a In general, in addition to installing a smoke detector, a temperature sensor can be installed in the space to reduce the probability of false alarms from the sensor. In this case, the detection module 21 can only determine a fire alarm event when it receives the fire alarm event sent by the smoke detection sensor and the fire alarm event sent by the temperature sensor at the same time.

For false alarm events, the user can use the user interface 71 of the networking device 7 to log into the operation interface 25 of the door and window control platform 2 to stop subsequent operations of the door and window control platform 2. The operation interface 25 will notify the control module 22 to stop the alarm. The operation of the device 6 is stopped, and the closing command is stopped to the control module 42 of the electric door bow 4 and the control module 52 of the electric window opener 5, and the false alarm event is added and the operation status of the fire protection equipment is updated to the data. Library 23.

According to statistics from the Fire Department of the Ministry of the Interior of the Republic of China, the main cause of casualties at fire scenes is the difficulty in escaping after being choked by thick smoke. This is because the smoke in the fire contains toxic components such as carbon monoxide, carbon dioxide, and toxic gases. gas. If the human body inhales too much smoke, it will cause coma or shock. Therefore, if the spread of smoke can be prevented in the fire scene, the chance of rescue will be effectively improved. However, people in a building may panic to escape from a fire, and then open a door or window without closing it, causing the fire or smoke to quickly spread to other spaces, or they may open the window at will to call for help. , but instead injects more fresh air into the fire, causing the fire to get out of control. Therefore, the purpose of the present invention is to assist fire scene personnel to close doors and windows when escaping, so as to effectively block the rapid spread of thick smoke or fire and reduce casualties.

A building may contain multiple rooms, and the doors or windows of each room may be configured in various ways, as shown in Table 1, for example. Each column in Table 1 represents a room, V indicates that the room is configured with a door or a window, and X indicates that the room is not configured with a door (for example, only an entrance and exit without a door) or a window. When a fire occurs, if the people in the building cannot escape the fire in time, they should quickly find a suitable refuge space. For rooms with doors and no windows, although there are no windows to the outside Subsequent rescue, but if the door of the room can be closed, it will block the entry of thick smoke and increase the chance of rescue. For a room with no door but a window, since there is no door to block the entry of heavy smoke, and opening the window will inject fresh air and expand the disaster, so although the room is not suitable for evacuation, closing the window will effectively suppress the spread of the fire. According to the types of rooms listed in Table 1, rooms with doors and windows are relatively suitable spaces for taking refuge and waiting for rescue during a fire escape. In addition to blocking heavy smoke through the door, this room can also Open the window to exhaust the poisonous gas in the space and wait for external rescue. However, the most easily overlooked factor in this situation is opening the window before closing the door, causing the fire smoke to quickly spread into the room, and The rapid influx of fresh air from the window further fuels the fire, significantly reducing the chance of rescue. Based on the above analysis, the present invention periodically detects and closes the doors and windows of the room, which will effectively slow down the spread of fire and reduce casualties. In addition, in order not to prevent people from escaping through windows or waiting for rescue, after periodically closing the paired door and window, if it is detected that the window is open and the door is closed, it will be deemed that the window has been blocked by an external force. is open and an escape or rescue operation is in progress, thus stopping the periodic detection and periodic closing of the window.

In step S102, the detection module 21 of the door and window control platform 2 periodically sends signals to each electric motor at intervals of the time interval B during a fire alarm event (that is, from the time after receiving the fire alarm event to when the fire alarm event is cleared). The detection module 41 of the door bow 4 queries the opening and closing status of the corresponding door, and periodically queries the detection module 51 of each electric window opener 5 for the opening and closing of the corresponding window. condition. The detection module 21 then notifies the control module 22 to send a closing command to the control module 42 of the electric door bow 4 or the electric window opener 5 for each electric door bow 4 or electric window opener 5 that is in the open state. The control module 52 of the device 5 is used to cause the control module 42 of the electric door bow 4 or the control module 52 of the electric window opener 5 to close the corresponding door or window (i.e., periodically close the door and window). . Among them, if the control module 42 of the electric door bow 4 or the control module 52 of the electric window opener 5 is in the process of closing the door or the window, the infrared transmitter installed on the door or the window When a blocking event occurs with the infrared receiver, the control module 42 or the control module 52 immediately stops closing the door or the window and opens the door or the window. After the time interval B, the detection module 21 of the door and window control platform 2 periodically queries the detection module 41 of each electric door bow 4 and the detection module 51 of each electric window opener 5 for the corresponding information. The opening and closing status of the door and window, and the detection module 21 then notifies the control module 22 to send a closing command to each electric door bow 4 or electric window opener 5 in the open state. The control module 42 or the control module 52 of the electric window opener 5 . The detection module 21 of the door and window control platform 2 periodically detects and closes the doors and windows of the building according to the above method until the control module 22 receives the stop command sent by the operating interface 25 or all fire protection equipment. until the detection modules are all offline.

In step S103, the detection module 21 of the door and window control platform 2 obtains a list of the electric door bow 4 and the electric window opener 5 of the paired door and window from the database 23 in advance. In step S102, the detection module 21 specifically records the detection module 41 and the detection module of the electric door bow 4 and the electric window opener 5 corresponding to the paired doors and windows. 51 The reported opening and closing status. When the detection modules 41 and 51 both report that they are in the open state, the detection module 21 still notifies the control module 22 to send a closing command to the electric door bow 4 of the paired door according to step S102. The control module 42 and the control module 52 of the electric window opener 5 of the paired window. When the detection module 41 of the electric door bow 4 of the paired door reports that it is in a closed state, and When the detection module 51 of the electric window opener 5 of the paired window changes from a closed state to an open state, the detection module 21 stops notifying the control module 22 to send a closing command to the electric opener of the paired window. The control module 52 of the window 5.

Before the fire alarm is lifted, people in the building may continue to escape or change their refuge locations due to changes in the fire intensity, and rescuers may also be conducting rescue operations outside the building. If the trapped people and rescuers can grasp the situation, The opening, closing and wiring status of each door and window in the building can effectively avoid spaces with serious fire hazards. For example, if the detection module 41 of the electric door bow 4 in the first room (with door and no window) is offline, and the detection module 41 of the electric door bow 4 in the fourth room (with door and window) on the same floor If both the group 41 and the detection module 51 of the electric window opener 5 report a closed state, then the fourth room is a relatively safe refuge space.

In step S104, the detection module 21 of the door and window control platform 2 periodically queries the detection module 31 of each sensor 3 and the detection module 41 of each electric door bow 4 and each electric window opener 5. The detection results, opening and closing status and connection status of the detection module 51 are detected, and the detection module 21 transmits the operation status reported by the fire protection equipment to the push module 24. In addition to updating the operation status of the fire protection equipment to the database 23, the push module 24 also publishes the operation status of the fire protection equipment to the operation interface 25 and the user interface 71 of the networking device 7 to display the status of each fire protection equipment. Detection results, opening and closing status and connection status.

In a fire alarm event, when the detection results reported by the detection module 31 of each sensor 3 are no fire alarm events (for example, the fire has been extinguished), the door and window control platform 2 will cancel the fire alarm event, wherein, the control The module 22 stops the operation of the alarm 6 and stops sending closing commands to the control module 42 of the electric door bow 4 and the control module 52 of the electric window opener 5 . Alternatively, the user can use the user interface 71 of the networking device 7 to log into the operation interface 25 of the door and window control platform 2 and issue an instruction to cause the door and window control platform 2 to cancel the fire alarm event.

In one embodiment, the present invention further provides a computer-readable medium, such as a memory, a floppy disk, a hard disk or an optical disk. The computer-readable medium can be applied to a computing device, a computer or a server, and stores instructions to execute the above door and window control method for reducing fire.

Based on the above, the door and window control system and method for reducing fire intensity of the present invention have the following advantages:

First, people in a building usually flee immediately when a fire breaks out, and it is difficult to close the doors and windows of the building one by one. The present invention uses automated control to quickly close all the doors and windows of the building, effectively Block out outside air to slow the spread of fire or smoke.

Secondly, people in the building may open the door again and then forget to close it during the panic escape process, causing thick smoke to escape. The present invention can effectively mitigate the risk through periodic detection and periodic closing of each door and window. Thick smoke spreads and increases the chances of people inside the house being rescued.

Third, through the mechanism of periodically closing the door, it is ensured that when people are evacuating for survival or waiting for rescue, the air convection caused by opening the windows and doors will not fuel the fire.

Fourth, if no one is in the building, the invention will automatically close all doors and windows of the building to slow down the spread of fire or smoke and effectively reduce property losses.
