Description

Technical Field

[0001] The present invention relates to the field of intelligent buildings, and particularly to an intelligent building integration system. Background Art

[0002] With the acceleration of the urbanization process and the popularization of high-rise buildings, the safety problem of building fires has become increasingly prominent. Due to the complex structure, dense population, and difficult evacuation of high-rise buildings, once a fire occurs, it often causes serious casualties and property losses. Traditional fire emergency response systems mainly rely on single sensors such as smoke detectors and temperature sensors for fire detection, and use basic equipment such as broadcast systems and emergency lighting for evacuation guidance. For example, a fire escape system with population statistics and fire detection with the application number CN202311422156.4 can only conduct population statistics on people and adopt traditional guidance methods of sound, light, and graphics, and cannot maximize the use of the detection system to actively rescue and dispatch trapped people during disaster relief. Summary of the Invention

[0003] In view of the drawback that the prior art cannot maximize the use of the detection system to actively rescue and dispatch trapped people during disaster relief, the present invention provides an intelligent building integration system.

[0004] To solve the above technical problems, the present invention is solved by the following technical solutions: An intelligent building integration system includes a monitoring subsystem, an elevator subsystem, and a lighting subsystem. The monitoring subsystem includes floor monitoring devices, elevator cabin monitoring devices, and a central processing module arranged on each floor. The elevator subsystem includes ordinary elevators, fire elevators equipped with fire isolation cabins, and an elevator control module. The lighting subsystem includes a lighting array that can be controlled in zones, an emergency lighting group with independent power supply, and an intelligent light control module. It further includes: a personnel situation perception subsystem and an intelligent emergency decision-making subsystem.

[0005] The personnel situation perception subsystem is connected to the monitoring subsystem and includes:

[0006] A daily personnel flow monitoring module that integrates the floor monitoring and elevator monitoring personnel flow data to construct the personnel distribution;

[0007] A millimeter-wave radar array for perceiving the number of people and the positions of people within the floor;

[0008] An electronic marking module configured with a floor plan of each floor, and marking the personnel number information and personnel position information on the corresponding floor plan according to the daily personnel flow monitoring module and the millimeter-wave radar array to generate an electronic rescue map;

[0009] The intelligent emergency decision-making subsystem includes:

[0010] An escape route generation module that generates the optimal escape path to the escape passage according to the electronic rescue map;

[0011] A dynamic scheduling module for scheduling fire elevators according to the personnel distribution;

[0012] The central processing module is preset with a fire alarm trigger condition. When it is detected that the fire alarm trigger condition is met, the emergency response mode is activated and the following operations are performed:

[0013] The elevator control module locks the ordinary elevator to the nearest safe floor and opens the control authority of the fire elevator;

[0014] The intelligent light control module cuts off the normal power supply of the affected floor and activates the emergency lighting group;

[0015] Start the millimeter-wave radar array to generate the electronic rescue map of the affected floor;

[0016] The display screen in the fire elevator cabin synchronously displays the electronic rescue map.

[0017] By adopting the above technical solutions, by integrating the monitoring subsystem, the elevator subsystem and the lighting subsystem, a complete intelligent building fire emergency response system is constructed, realizing multi-dimensional collaborative response during a fire. Through the daily personnel flow monitoring module and the millimeter-wave radar array, the personnel distribution and location in the building are sensed in real time to generate the electronic rescue map. The advantage of using the millimeter-wave radar is that in the smoke generated by the fire, compared with vision-based detection, the millimeter-wave radar has better penetration. It can calculate the number of people and their approximate locations based on the human body contour movement postures, etc., providing data support for subsequent emergency decision-making. Generate the optimal escape path according to the electronic rescue map, and optimize the use of the fire elevator through the dynamic scheduling module to improve the evacuation efficiency. When the fire alarm trigger condition is met, the system automatically executes the emergency response mode, including locking the ordinary elevator, activating the emergency lighting, generating the electronic rescue map, etc., reducing the delay of human intervention. The display screen in the fire elevator cabin synchronously displays the electronic rescue map to ensure that the evacuating personnel can obtain the rescue information in real time.

[0018] The present invention is further configured that the daily personnel flow monitoring module and the electronic marking module are provided with a cross-verification mechanism, and double verification of the number of people is performed through the data fusion of the counting of the millimeter-wave radar array and the video analysis algorithm. When the difference exceeds the preset threshold, an artificial review process is triggered.

[0019] By adopting the above technical solutions, through the cross-verification mechanism, combining the millimeter-wave radar array and the video analysis algorithm, double verification of the number of people in the building is performed, reducing the possibility of misjudgment and missed judgment, improving the data accuracy. When the difference between the two data sources exceeds the preset threshold, an artificial review process is triggered to ensure the reliability of the data and avoid decision-making mistakes caused by data errors.

[0020] The present invention is further configured such that: the lighting subsystem includes a projection device and an acoustic-optical guiding device; the escape route generation module generates an optimal escape path according to the electronic rescue map; the projection device generates an escape indicator according to the optimal escape path; and the acoustic-optical guiding device generates a differential audio signal with azimuth directivity according to the evacuation direction.

[0021] By adopting the above technical solution, the escape guidance is optimized. Through the projection device and the acoustic-optical guiding device, the optimal escape path is transmitted to the evacuees in the form of visual and auditory signals, improving the evacuation efficiency. For multi-sensory guidance, the differential audio signal has azimuth directivity and can effectively guide the evacuation of people in a noisy environment, reducing chaos. For dynamic path indication, the projection device dynamically adjusts the escape indicator according to the real-time generated electronic rescue map to ensure the accuracy and timeliness of the indication information.

[0022] The present invention is further configured such that: the projection device projects the electronic rescue map of the corresponding floor at the escape opening of each floor.

[0023] By adopting the above technical solution, for information visualization, the electronic rescue map is projected at the escape opening of each floor, enabling the evacuees to intuitively understand the fire situation and escape route of the current floor. For rapid decision-making support, through the visualized information, it helps the evacuees make quick escape decisions and reduces the hesitation time.

[0024] The present invention is further configured such that: the dynamic scheduling module is configured with an emergency evacuation strategy, and the emergency evacuation strategy includes:

[0025] When a single floor is affected by the disaster, the fire elevator goes directly to the affected floor to evacuate the people on the affected floor.

[0026] When multiple floors are affected by the disaster, the dynamic monitoring subsystem monitors the number of people staying at the elevator entrance and transfers the people on the affected floors downward to the nearest temporarily unaffected floor or the nearest refuge floor.

[0027] By adopting the above technical solution, for dynamic scheduling optimization, according to the specific situation of the fire occurrence (single or multiple floors affected), the scheduling strategy of the fire elevator is dynamically adjusted to maximize the evacuation efficiency. For the hierarchical evacuation strategy, when multiple floors are affected, the dynamic monitoring subsystem transfers the people on the affected floors to the unaffected floors or refuge floors to avoid congestion and secondary injuries.

[0028] The present invention is further configured such that: the escape route of the affected floor generates an escape path towards the fire elevator, the projection device simultaneously generates an escape indicator towards the fire elevator, and when multiple floors are affected, the elevator load limit is lifted.

[0029] By adopting the above technical solution, the escape route is optimized to generate an escape route towards the fire elevator on the affected floor, and an escape indicator is generated in combination with the projection device to ensure a clear evacuation direction and maximize the utilization of fire elevator resources. In case of multiple floors being affected, the elevator load limit is lifted to improve the transportation capacity of the fire elevator and speed up the evacuation speed.

[0030] The present invention is further configured such that: the intelligent emergency decision-making subsystem further includes a firefighter identification module and a firefighter terminal device. The firefighter identification module is used to identify firefighters entering the affected building. When the firefighter identification module detects that a firefighter enters the affected building, the control right of the fire elevator is automatically switched to the firefighter terminal, and the firefighter terminal can display a real-time electronic rescue map.

[0031] By adopting the above technical solution, support for firefighters is provided. Through the firefighter identification module and the firefighter terminal device, a real-time electronic rescue map is provided for firefighters to help them quickly understand the fire situation and the distribution of people. Regarding the control right switch, when a firefighter enters the affected building, the control right of the fire elevator is automatically switched to the firefighter terminal to ensure that firefighters can efficiently perform rescue tasks.

[0032] The present invention is further configured such that: when the firefighter terminal enters the affected floor, the projection device generates an indicator of the location of affected people towards the affected people according to the electronic rescue map.

[0033] By adopting the above technical solution, support for precise rescue is provided. When a firefighter enters the affected floor, the projection device generates an indicator of the location of affected people to help firefighters quickly locate trapped people, improve the rescue efficiency, and update information in real time. Combined with the electronic rescue map, it is ensured that the information obtained by firefighters is the latest, avoiding rescue delays caused by information lag.

[0034] The present invention is further configured such that: the floor monitoring device further includes a temperature sensor, a smoke sensor, and a CO concentration sensor. The central processing module sets a multi-modal alarm verification mechanism. When any two of the temperature sensor, the smoke sensor, and the CO concentration sensor reach the threshold and the infrared imaging shows an abnormal heat source, a fire confirmation is triggered.

[0035] By adopting the above technical solution, the fire confirmation mechanism: through the multi-modal alarm verification mechanism (temperature, smoke, CO concentration sensors and infrared imaging), the accuracy of fire detection is improved and the false alarm rate is reduced. Abnormal heat source detection: combined with infrared imaging technology, it can quickly identify abnormal heat sources and further confirm the occurrence of a fire.

[0036] The present invention is further configured such that: the central processing module generates a fire intensity index for the affected floor according to the multi-modal alarm verification mechanism, and the fire level is synchronized with the electronic rescue map.

[0037] Due to the adoption of the above technical solutions, the present invention has remarkable technical effects: for the assessment of the fire situation, a fire index is generated through a multi-modal alarm verification mechanism to quantify the severity of the fire, providing a scientific basis for emergency decision-making. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 It is a system framework diagram of an intelligent building integration system. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] The present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0040] Embodiment:

[0041] The intelligent building integration system of the present application includes a monitoring subsystem, an elevator subsystem, a lighting subsystem, a personnel situation perception subsystem, and an intelligent emergency decision-making subsystem. The monitoring subsystem includes floor monitoring devices, elevator cabin monitoring devices, and a central processing module provided on each floor. The elevator subsystem includes ordinary elevators, fire elevators configured with fire isolation cabins, and an elevator control module. The lighting subsystem includes a lighting array that can be controlled in zones, an emergency lighting group with independent power supply, and an intelligent light control module.

[0042] The personnel situation perception subsystem is connected to the monitoring subsystem and includes a daily personnel flow monitoring module that integrates the personnel flow data of floor monitoring and elevator monitoring to construct the personnel distribution.

[0043] A millimeter-wave radar array for sensing the number of people and the positions of people within the floor.

[0044] An electronic marking module is configured with a floor plan of each floor, and marks the personnel quantity information and personnel position information on the corresponding floor plan according to the daily personnel flow monitoring module and the millimeter-wave radar array to generate an electronic rescue map. The intelligent emergency decision-making subsystem includes an escape route generation module that generates an optimal escape path according to the electronic rescue map; a dynamic scheduling module for scheduling the fire elevator according to the personnel distribution. The central processing module presets a fire alarm trigger condition. When it detects that the fire alarm trigger condition is met, it activates the emergency response mode, executes the elevator control module to lock the ordinary elevator to the nearest safe floor and open the control permission of the fire elevator; the intelligent light control module cuts off the normal power supply of the affected floor and starts the emergency lighting group; starts the millimeter-wave radar array to generate an electronic rescue map of the affected floor; the display screen in the fire elevator cabin synchronously displays the electronic rescue map.

[0045] The intelligent building integration system solves the problems of personnel evacuation and emergency response in high-rise building fires through the linkage of the monitoring subsystem, elevator subsystem, and lighting subsystem. The monitoring subsystem monitors the personnel distribution on floors and in elevators in real time. The elevator subsystem ensures the safe evacuation of personnel through fire elevators and elevator control modules. The lighting subsystem provides emergency lighting. The personnel situation awareness subsystem and the intelligent emergency decision-making subsystem integrate the monitoring data, generate an electronic rescue map and the optimal escape route, and dispatch the fire elevator. The central processing module activates the emergency response mode under fire alarm trigger conditions to ensure the coordinated operation of each subsystem. Through the mutual cooperation of these technical features, the timely evacuation and rescue of trapped personnel in case of fire are achieved.

[0046] In high-rise buildings, during a fire, the evacuation of personnel and emergency response are two key issues. Traditional fire emergency systems often rely on a single sensor for fire detection, lacking accurate knowledge of the real-time location and quantity of personnel, resulting in low evacuation efficiency. The intelligent building integration system of this application solves this problem by introducing a personnel situation awareness subsystem and an intelligent emergency decision-making subsystem. The personnel situation awareness subsystem integrates the flow data of floor monitoring and elevator monitoring, uses a millimeter-wave radar array to sense the quantity and location of personnel on the floor, and generates an electronic rescue map on the floor plan through an electronic marking module. The intelligent emergency decision-making subsystem generates the optimal escape route based on the electronic rescue map and dispatches the fire elevator through a dynamic dispatching module to ensure the safe evacuation of personnel. The central processing module presets the fire alarm trigger conditions and activates the emergency response mode when a fire alarm is detected to ensure the coordinated operation of each subsystem, thus achieving efficient personnel evacuation and emergency response.

[0047] The intelligent building integration system of this application is superior to the prior art in many aspects. Compared with the traditional fire emergency system that relies on a single sensor, this application, through the personnel situation awareness subsystem and the intelligent emergency decision-making subsystem, achieves accurate knowledge of the real-time location and quantity of personnel, generates an electronic rescue map and the optimal escape route, significantly improving the evacuation efficiency. In addition, when the central processing module of the system detects a fire alarm, it can automatically activate the emergency response mode to ensure the coordinated operation of each subsystem, thus achieving efficient personnel evacuation and emergency response. The mutual cooperation of these technical features enables this application to evacuate and rescue trapped personnel more timely and effectively in case of fire.

[0048] Furthermore, this application also proposes to set a cross-verification mechanism for the daily personnel flow monitoring module and the electronic marking module, and conduct double-person number verification through the data fusion of the counting of the millimeter-wave radar array and the video analysis algorithm. When the difference exceeds the preset threshold, an artificial review process is triggered.

[0049] The technical features include setting a cross - verification mechanism between the daily personnel flow monitoring module and the electronic marking module. Double - person - number verification is carried out through the data fusion of the counting of the millimeter - wave radar array and the video analysis algorithm. When the difference exceeds the preset threshold, an artificial review process is triggered. These technical features cooperate with each other to play a role in solving the problem of inconsistent personnel flow monitoring data and the actual number of people. Through the cross - verification mechanism between the daily personnel flow monitoring module and the electronic marking module, combined with the data fusion of the counting of the millimeter - wave radar array and the video analysis algorithm, the accuracy of personnel number monitoring can be effectively improved. When the difference between the monitoring data and the actual number of people exceeds the preset threshold, the system will automatically trigger an artificial review process, thus ensuring the accuracy of the personnel number information and avoiding emergency response errors caused by inconsistent data.

[0050] The cross - verification mechanism between the daily personnel flow monitoring module and the electronic marking module can be implemented in various ways. For example, the millimeter - wave radar array can be arranged at the entrances, exits and important passages of the building to monitor the number and location of people entering and leaving in real - time. The video analysis algorithm uses the cameras installed on each floor and in the elevators to analyze and count the movement trajectories of people. When the difference between these two data sources exceeds the preset threshold, the system will automatically generate an alarm and start the artificial review process. The artificial review process can include ways such as retrieving surveillance videos and on - site personnel verification to ensure the accuracy of the data.

[0051] This application provides a more accurate and reliable method for monitoring the number of people through the cross - verification mechanism between the daily personnel flow monitoring module and the electronic marking module, combined with the data fusion of the counting of the millimeter - wave radar array and the video analysis algorithm. Compared with the traditional single - data - source monitoring method, this double - verification mechanism can effectively reduce the situation of inconsistent monitoring data and the actual number of people, ensure the accuracy of the personnel number information, and thus improve the reliability and effectiveness of the emergency response.

[0052] Furthermore, this application also proposes that the lighting subsystem includes a projection device and an acoustic - optical guidance module. The escape route generation module generates the optimal escape path according to the electronic rescue map. The projection device generates escape indicators according to the optimal escape path. The acoustic - optical guidance module generates a differential audio signal with azimuth directivity according to the evacuation direction.

[0053] The lighting subsystem includes a projection device and an acoustic-optical guidance module. The escape route generation module generates an optimal escape path based on the electronic rescue map. The projection device generates an escape indicator according to the optimal escape path. The acoustic-optical guidance module generates a differential audio signal with azimuth directivity according to the evacuation direction. Through the mutual cooperation of these technical features, the problem of guiding people to escape in case of a fire emergency is effectively solved. The projection device provides a visual escape indicator, and the acoustic-optical guidance module indicates the direction through the audio signal. Combining with the optimal escape path generated by the electronic rescue map, it can quickly and accurately guide people to safely evacuate from the fire scene.

[0054] The projection device can use a laser projector or an LED projection device installed on the ceiling or wall of each floor to project a clear escape route map. The acoustic-optical guidance module can emit a directional audio signal and flashing lights through speakers and lighting devices installed in the corridor or room to guide people to escape in the correct direction. The escape route generation module can dynamically generate an optimal escape path through the pre-stored building floor plan and real-time monitored personnel distribution data.

[0055] The lighting subsystem of this application provides a multi-sensory escape indication method by combining a projection device and an acoustic-optical guidance module. Compared with the traditional single indication method, it can more effectively guide people to escape. At the same time, the escape route generation module ensures the optimality and real-time nature of the escape path according to the real-time updated electronic rescue map, improving the efficiency and safety of fire emergency response.

[0056] Furthermore, this application also proposes that the projection device projects the electronic rescue map of this floor at the escape exit of each floor.

[0057] The projection device projects the electronic rescue map of this floor at the escape exit of each floor, which can provide clear and visible escape information in case of an emergency. This technical feature enables trapped people to quickly obtain the escape path information of the current floor by projecting the electronic rescue map at the escape exit of each floor, thus improving the escape efficiency and safety.

[0058] The projection device can be implemented in various forms, such as laser projection, LED projection or LCD projection and other technical means. These projection devices can provide high brightness and high contrast display effects under different ambient light conditions to ensure that the electronic rescue map is still clearly visible in case of an emergency. Further, the projection device can be integrated into the wall or ceiling to save space and provide a better visual effect. In addition, the projection device can be linked with the floor monitoring device and the central processing module. When the fire alarm trigger condition is met, the projection function is automatically activated to update and project the electronic rescue map of the current floor in real time.

[0059] By projecting the electronic rescue map of each floor at the emergency exits of each floor, the present application significantly improves the visibility and accessibility of the escape route information compared with the prior art. Thus, trapped persons can quickly understand the best escape route in case of emergency, reduce the escape delay caused by getting lost or unclear information, and improve the overall escape efficiency and safety.

[0060] Furthermore, the present application also proposes that the dynamic scheduling module is configured with an emergency evacuation strategy, which includes: when a single floor is affected by a disaster, the fire elevator directly reaches the affected floor to evacuate the people on the affected floor; when multiple floors are affected by a disaster, the dynamic monitoring subsystem monitors the number of people staying at the elevator entrance, and transfers the people on the affected floors downward to the nearest temporarily unaffected floor or the nearest refuge floor.

[0061] The dynamic scheduling module and the emergency evacuation strategy play an important role in solving the technical problem of how to effectively evacuate people and optimize the evacuation route when multiple floors are affected by a disaster. The dynamic scheduling module can adjust the evacuation strategy in real time by monitoring the number of people staying at the elevator entrance to ensure the efficiency and safety of the evacuation process. The emergency evacuation strategy provides a specific evacuation plan. When a single floor is affected by a disaster, the fire elevator directly reaches the affected floor for evacuation; when multiple floors are affected by a disaster, the dynamic monitoring subsystem monitors the number of people staying at the elevator entrance, and transfers the people on the affected floors downward to the nearest temporarily unaffected floor or the nearest refuge floor. These technical features cooperate with each other to ensure that people can be effectively evacuated in case of multiple floors being affected by a disaster, reducing casualties and property losses.

[0062] The dynamic scheduling module can be implemented in the following way: First, the dynamic monitoring subsystem monitors the number of people staying in real time through the cameras and sensors installed at the elevator entrance, and transmits the data to the central processing module. The central processing module dynamically adjusts the scheduling plan of the fire elevator according to the preset emergency evacuation strategy. When a single floor is affected by a disaster, the central processing module instructs the fire elevator to directly reach the affected floor to evacuate people. When multiple floors are affected by a disaster, the central processing module calculates the optimal evacuation route based on the data of the number of people staying at the elevator entrance, and transfers the people on the affected floors downward to the nearest temporarily unaffected floor or the nearest refuge floor. During the evacuation process, the fire elevator can also display the electronic rescue map in real time through the display screen in the elevator car to guide the affected people to evacuate quickly and safely.

[0063] Thus, through the combination of the dynamic scheduling module and the emergency evacuation strategy, the present application provides a technical solution for effectively evacuating people and optimizing the evacuation route when multiple floors are affected by a disaster. Compared with the traditional evacuation method, the present application can monitor the number of people staying at the elevator entrance in real time, dynamically adjust the evacuation strategy, improve the efficiency and safety of the evacuation process, and further optimize the evacuation route by transferring the people on the affected floors downward to the nearest temporarily unaffected floor or the nearest refuge floor, reducing the evacuation time of people and lowering casualties and property losses.

[0064] Furthermore, the present application also proposes that the escape route of the affected floor generates an escape path towards the fire elevator, and the projection device simultaneously generates an escape indicator towards the fire elevator. When multiple floors are affected, the elevator load limit is lifted.

[0065] By generating an escape path and an indicator towards the fire elevator, it is possible to effectively guide the affected people to quickly find the escape route. Lifting the elevator load limit can increase the evacuation capacity of the elevator, ensuring that more people can be evacuated in time, thereby improving the overall escape efficiency and safety.

[0066] The generation of the escape route can be achieved by combining an electronic rescue map and an optimal escape path algorithm. The projection device can adopt technologies such as laser projection and LED projection to ensure that the escape indicator can be clearly displayed under various light conditions. Lifting the elevator load limit can be achieved by modifying the parameters of the elevator control system to ensure that the elevator can maximize its carrying capacity in case of an emergency. Specifically, the projection device can be installed at key positions on the floor, such as corridors and stairwells, to project the escape indicator in real time, guiding the affected people towards the fire elevator. The elevator control system can preset an emergency mode to automatically lift the load limit when it detects that multiple floors are affected, ensuring that the elevator can carry more people for evacuation.

[0067] Thus, through the technical means of generating an escape path towards the fire elevator, projecting an escape indicator, and lifting the elevator load limit, the present application effectively solves the problems of providing an effective escape route and lifting the elevator load limit when multiple floors are affected. Compared with the prior art, the present application can more quickly guide the affected people to find the escape path and improve the evacuation capacity of the elevator, thereby significantly improving the escape efficiency and safety.

[0068] Furthermore, the present application also proposes that the intelligent emergency decision-making subsystem further includes a firefighter identification module and a firefighter terminal device. The firefighter identification module is used to identify the firefighters entering the affected building. When the firefighter identification module monitors that a firefighter enters the affected building, the control right of the fire elevator automatically switches to the firefighter terminal, and the firefighter terminal can display a real-time electronic rescue map.

[0069] The intelligent emergency decision-making subsystem includes a firefighter identification module and a firefighter terminal device. The firefighter identification module identifies the firefighters entering the affected building to ensure that the firefighters can quickly take over the control right of the elevator. The firefighter terminal device displays a real-time electronic rescue map to provide the latest rescue information. These technical features work together to ensure that in case of a fire emergency, the firefighters can quickly take over the control right of the elevator and obtain real-time rescue information, thereby improving the rescue efficiency and safety.

[0070] The firefighter identification module can be implemented by various technical means. For example, the identity of firefighters can be verified through RFID tags, facial recognition, fingerprint recognition, etc. The firefighter terminal device can be a portable handheld device or a fixed device installed in a fire elevator. The terminal device interacts with the central processing module through wireless communication technology to display the electronic rescue map in real time and update it according to the actual situation. In this way, firefighters can immediately master the rescue information after entering the affected building, make quick emergency decisions, and improve the rescue efficiency.

[0071] By adding a firefighter identification module and a firefighter terminal device, the intelligent emergency decision-making subsystem of this application can quickly identify the firefighters entering the affected building during a fire and automatically switch the control right of the fire elevator to the firefighter terminal, ensuring that firefighters can quickly take over the elevator control right. At the same time, the firefighter terminal device can display the electronic rescue map in real time and provide the latest rescue information to help firefighters carry out rescue operations more effectively. Compared with the prior art, this application has significant advantages in improving rescue efficiency and safety.

[0072] Furthermore, this application also proposes that when the firefighter terminal enters the affected floor, the projection device generates a disaster victim position indicator towards the disaster victims according to the electronic rescue map.

[0073] By generating a disaster victim position indicator using the projection device when the firefighter enters the affected floor, the position of the disaster victims can be quickly and intuitively indicated. This technical feature plays an important role in solving the problem of how to quickly indicate the position of the disaster victims when the firefighter enters the affected floor to improve the rescue efficiency.

[0074] Specifically, the projection device can automatically generate and project the position indicator of the disaster victims through the preset electronic rescue map when the firefighter terminal enters the affected floor. The indicator can intuitively display the specific position of the disaster victims in the form of arrows, flashing light points, etc. As a preferred implementation, the projection device can be installed on the ceiling or wall of the floor to ensure that the indicator is clearly visible within the sight range of the firefighter. In addition, the projection device can combine the floor plan and real-time monitoring data to dynamically adjust the display of the disaster victim position indicator to ensure the accuracy and timeliness of the information.

[0075] Thus, the technical solution of this application significantly improves the rescue efficiency by generating a disaster victim position indicator using the projection device when the firefighter enters the affected floor. Compared with the prior art, the technical solution of this application can not only quickly indicate the position of the disaster victims but also provide intuitive visual guidance, reducing the search time of firefighters in complex environments and improving the accuracy and timeliness of the rescue.

[0076] Furthermore, the present application also proposes that the floor monitoring device includes a temperature sensor, a smoke sensor, and a CO concentration sensor. The central processing module sets up a multi-modal alarm verification mechanism. When any two of the temperature sensor, the smoke sensor, and the CO concentration sensor reach the threshold and the infrared imaging shows an abnormal heat source, a fire confirmation is triggered.

[0077] By integrating a temperature sensor, a smoke sensor, and a CO concentration sensor and setting up a multi-modal alarm verification mechanism, the present application can more accurately confirm the occurrence of a fire. The multi-modal alarm verification mechanism combines the data of multiple sensors. When any two sensors reach the threshold and the infrared imaging shows an abnormal heat source, a fire confirmation is triggered. This method improves the accuracy of fire confirmation and reduces the possibility of false alarms, thus more effectively ensuring the safety of the personnel in the building.

[0078] The temperature sensor, the smoke sensor, and the CO concentration sensor are respectively used to detect the ambient temperature, the smoke concentration, and the carbon monoxide concentration. Through the multi-modal alarm verification mechanism, when the data of any two sensors are detected to reach the preset threshold and the infrared imaging shows the existence of an abnormal heat source, a fire can be confirmed. This method of multi-sensor data fusion can exclude the false alarms of a single sensor and improve the accuracy of fire confirmation. Further, the temperature sensor can adopt a thermocouple or a thermistor, the smoke sensor can adopt a photoelectric type or an ionization type, the CO concentration sensor can adopt an electro-chemical type or an infrared absorption type, and the infrared imaging device is used to detect the heat source distribution in the building and can intuitively display the position of the abnormal heat source.

[0079] Through the multi-modal alarm verification mechanism and by combining the data of the temperature sensor, the smoke sensor, and the CO concentration sensor, the present application improves the accuracy of fire confirmation and reduces the possibility of false alarms. Compared with the traditional single-sensor fire alarm system, the present application can confirm the fire more timely and accurately, thus more effectively ensuring the safety of the personnel in the building.

[0080] Furthermore, the present application also proposes that the central processing module generates a fire intensity index of the affected floor according to the multi-modal alarm verification mechanism, and the fire level is synchronized with the electronic rescue map.

[0081] Through the multi-modal alarm verification mechanism, the central processing module can timely confirm the fire and generate a fire intensity index of the affected floor. The fire level is synchronized onto the electronic rescue map, providing more intuitive fire information for the rescue personnel to assist them in making scientific decisions and effective rescues.

[0082] The multi-modal alarm verification mechanism includes the comprehensive use of a temperature sensor, a smoke sensor, a CO concentration sensor, and infrared imaging. When any two of the temperature sensor, the smoke sensor, and the CO concentration sensor reach the threshold and the infrared imaging shows an abnormal heat source, the central processing module triggers a fire confirmation. The generation of the fire index can be based on a weighted algorithm of different sensor data, comprehensively considering factors such as fire intensity and spread speed. When the fire level is synchronized to the electronic rescue map, it can be displayed in a graphical way, for example, using different colors or marks to represent different fire levels. Specifically, the fire index can be divided into slight, medium, severe, etc. according to the preset levels and displayed correspondingly on the electronic rescue map.

[0083] Thus, through the multi-modal alarm verification mechanism, this application ensures the accuracy and timeliness of fire confirmation. The generated fire index and the synchronized fire level map provide more accurate and real-time fire information for rescue personnel, which helps to improve rescue efficiency and safety. Compared with the prior art, this application can perceive the fire situation more comprehensively and provide more intuitive fire information, significantly enhancing the ability and effect of fire emergency response.
