Description

Technical Field

[0001] This invention relates to the field of fire emergency rescue technology, and more specifically to a fire rescue linkage system. Background Technology

[0002] With the acceleration of urbanization and the increasing prevalence of high-rise buildings, the suddenness, high hazard, and difficulty of fire fighting have become a focus of social concern. Existing fire alarm and linkage systems typically use traditional smoke and heat detectors in conjunction with local alarms or simple central control linkage methods.

[0003] For example, patent CN220070572U discloses a fire-fighting robot, including multiple fire extinguishers, multiple multi-view cameras, a battery, an electric push rod, and a main controller mounted on the robot's main body. While such existing technologies can actively detect fires and extinguish them through sensors, they still have significant limitations in practical applications: existing linkage systems mostly rely on local area networks or discrete control components, lacking systematic remote interaction capabilities. When a fire occurs, manual alarm confirmation is often required, or the control logic is too simple to achieve multi-faceted information dissemination and proactive rescue linkage in the early stages of a disaster. This results in situations where personnel cannot evacuate in time or access control cannot be manually opened, making it difficult for fire and rescue forces to obtain accurate fire information and quickly enter the scene, thus delaying the best opportunity for firefighting and rescue.

[0004] Therefore, how to design a fire protection system that can achieve multimodal accurate monitoring, active communication alarm and automated coordination of rescue equipment, in order to solve the deficiencies of existing systems in fire linkage and remote rescue control, has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] In view of this, the present invention provides a fire rescue linkage system, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fire rescue linkage system includes a distributed sensor network deployed within a target area, comprising multiple independent sub-transmitter nodes for real-time acquisition of ambient temperature data, reception of physical button signals from personnel, and pickup of ambient voice signals; an intelligent main control center wirelessly connected to the distributed sensor network, with a built-in microprocessor configured to perform multi-modal joint judgment of fire hazard based on received signals from the sub-transmitter nodes, and generate a targeted rescue data packet containing absolute physical coordinates and trigger source tags when preset alarm conditions are met; a communication dispatch module integrated within the intelligent main control center, configured to send alarm information from the targeted rescue data packet to multiple preset tiered terminals via concurrent outbound voice calls and SMS messages, the tiered terminals including at least user terminals, neighbor terminals, property control terminals, and fire dispatch terminals; an access control execution unit deployed at the entrances and exits of the target area, communicatively connected to the intelligent main control center, configured to receive access control linkage commands and control door lock status; and a linkage rescue robot deployed on the periphery of the target area or in public areas, configured to receive alarm physical coordinates and control commands from the intelligent main control center, move towards the target area, and perform detection and rescue actions.

[0008] Therefore, this invention effectively solves the technical problems of slow response, narrow information coverage, and disconnected rescue coordination in traditional fire alarm systems through a collaborative architecture of distributed sensor networks, intelligent main control hubs, communication scheduling modules, access control execution units, and coordinated rescue robots. By real-time reporting of multimodal sensing data and precise generation of targeted rescue data packets, it achieves rapid identification of fire hazards and multi-level concurrent accurate alarms. At the same time, by utilizing the command interaction between the main control hub and the coordinated rescue robots, it realizes a closed-loop response from alarm to automatic on-site detection and rescue takeover, greatly improving the intelligence level of fire rescue and emergency response efficiency, thereby effectively protecting the safety of personnel at critical moments.

[0009] Preferably, the sub-transmitter node includes a temperature sensor, physical buttons, and a sound pickup module. The microprocessor's multi-modal joint fire hazard determination logic includes: physical environment level triggering: when the temperature sensor of any sub-transmitter node detects that the ambient temperature exceeds 100°C for a continuous preset duration, it is determined to be a real fire with the highest confidence level; human signal level triggering: when the physical button level signal of the sub-transmitter node is received, or when the preset distress call voiceprint characteristics are recognized by the sound pickup module in combination with the voice recognition module, it is determined to be a level two distress call warning.

[0010] Preferably, a hierarchical access control linkage mechanism is configured between the intelligent main control center and the access control execution unit: when the trigger is determined to be at the physical environment level, the intelligent main control center sends the highest-level emergency unlocking command to the access control execution unit to forcibly unlock the door; when the trigger is determined to be at the human signal level, the intelligent main control center does not send an unlocking command, and the access control execution unit remains locked and anti-theft.

[0011] Preferably, a near-field dynamic authentication communication channel is established between the joint rescue robot and the access control execution unit. When a human-induced signal trigger occurs, the intelligent main control center generates a one-time dynamic digital key and packages the key into the control command sent to the joint rescue robot. When the joint rescue robot moves into the near-field range of the access control execution unit, it initiates a near-field encrypted handshake matching. After successful matching, the access control execution unit unlocks and releases the joint rescue robot.

[0012] Preferably, the system also includes indoor monitoring equipment, and the intelligent main control hub also supports remote verification and manual secondary authorization verification: when an alarm occurs, the camera module of the indoor monitoring equipment and the linkage rescue robot is forcibly awakened, and a real-time video stream is pushed to the user terminal or the property control terminal; the access control execution unit is configured to receive a one-time remote unlocking command issued by the user terminal that has been verified by biometrics or password.

[0013] Preferably, the distributed sensor network and the intelligent main control center communicate using frequency hopping spread spectrum technology and have an anti-interference disconnection early warning mechanism: the sub-transmitter nodes send encrypted heartbeat packets to the intelligent main control center at a preset period; when the intelligent main control center loses the heartbeat packets of any sub-transmitter node consecutively, it triggers a zone security alarm independent of the fire alarm and pushes the suspected interference disconnection information to the user terminal.

[0014] Preferably, the intelligent main control center and all sub-transmitter nodes are equipped with a dual-circuit survival power supply system and a heterogeneous dual-network communication mechanism: the dual-circuit survival power supply system includes a mains power / low-voltage DC input module and a built-in rechargeable battery module, configured to seamlessly switch to built-in battery power supply when the external mains power fails; the heterogeneous dual-network communication mechanism includes a wireless local area network module and an independent cellular wide area IoT module. When the wireless local area network is detected to be disconnected, the communication scheduling module forcibly wakes up the cellular wide area IoT module to send alarm information.

[0015] Preferably, the absolute physical coordinates embedded in the targeted rescue data package adopt a hierarchical structured data format, specifically including: city, district, road / street, community number, building number, floor number, and precise room number.

[0016] Preferably, the joint rescue robot is equipped with a smoke-resistant composite sensor navigation module; the smoke-resistant composite sensor navigation module includes an optical camera, a millimeter-wave radar, and an infrared thermal imager; among them, the millimeter-wave radar is used to penetrate the smoke environment for physical obstacle avoidance and spatial modeling, and the infrared thermal imager is used to locate the center of the high-temperature fire source and the thermal radiation profile of personnel in the blinding smoke.

[0017] Preferably, after the rescue robot reaches the designated location at the absolute physical coordinates, it automatically grants its underlying motion control permissions, video pan-tilt control permissions, and fire extinguishing equipment trigger permissions to the pre-authorized user terminals and fire dispatch terminals through the intelligent main control center or cloud dispatch platform.

[0018] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a fire rescue linkage system with the following beneficial effects: This application, through the collaboration of a distributed sensor network and an intelligent main control center, utilizes multimodal sensing data real-time reporting and targeted rescue data packet generation technology, changing the existing situation of single fire monitoring and delayed alarm response. The system's hierarchical access control linkage mechanism and near-field dynamic authentication communication channel achieve a high balance between fire rescue efficiency and physical anti-theft security. Furthermore, through the anti-smoke composite sensor navigation module and dual-network dual-power redundancy design, the system ensures stable communication and navigation rescue capabilities even in harsh fire environments, fundamentally solving the technical defects of traditional systems that cannot accurately link rescue equipment in the early stages of a disaster and are easily interfered with during the rescue process.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] See appendix Figure 1 To be continued Figure 3 This invention discloses a fire rescue linkage system, including a distributed sensor network 10 deployed in a target area, comprising multiple independent sub-transmitter nodes 11 for real-time acquisition of ambient temperature data, reception of physical button signals from personnel, and pickup of ambient voice signals; an intelligent main control center 20 wirelessly connected to the distributed sensor network 10, with a built-in microprocessor 21 configured to perform multi-modal joint determination of fire hazard based on the received signals from the sub-transmitter nodes 11, and generate a targeted rescue data packet containing absolute physical coordinates and trigger source tags when preset alarm conditions are met; and a communication scheduling module 22 integrated within the intelligent main control center 20. The system is configured to send alarm information to multiple pre-set tiered terminals 50 via concurrent outbound voice calls and SMS messages, including at least user terminals 51, neighbor terminals 52, property control terminals 53, and fire dispatch terminals 54. Access control execution units 30, deployed at the entrances and exits of the target area, are communicatively connected to the intelligent main control hub 20 and are configured to receive access control linkage commands and control door lock status. A coordinated rescue robot 40, deployed on the periphery of the target area or in public areas, is configured to receive alarm physical coordinates and control commands from the intelligent main control hub 20, move towards the target area, and perform detection and rescue actions. Thus, through this collaborative architecture, comprehensive perception and precise dispatch of fire hazard information are achieved, greatly improving emergency response speed.

[0024] In one embodiment, the sub-transmitter node 11 includes a temperature sensor 111, a physical button 112, and a microphone module 113. The fire hazard multimodal joint determination logic of the microprocessor 21 includes: physical environment level triggering: when the temperature sensor 111 of any sub-transmitter node 11 detects that the ambient temperature exceeds 100°C for a continuous preset duration, it is determined to be a real fire with the highest confidence level; human signal level triggering: when the physical button 112 of the sub-transmitter node 11 is received, or when the preset distress call voiceprint features are recognized by the microphone module 113 in combination with the voice recognition module, it is determined to be a level two distress call warning. Among them, the sub-transmitter node 11 integrates a microcontroller and a wireless radio frequency module. The microcontroller has a built-in real-time clock timer, which is used to periodically wake up the wireless radio frequency module in deep sleep to send encrypted heartbeat packets to realize system health self-check; at the same time, the microcontroller reserves an external hardware interrupt pin to connect the temperature sensor 111 and the physical button 112. When a level change is detected, the wireless radio frequency module is driven to send an emergency trigger signal first. Therefore, by using multimodal cross-validation and a low-level interrupt wake-up structure, accurate identification of fire types and millisecond-level real-time reporting of emergencies are achieved, effectively reducing the false alarm rate of the system.

[0025] In some embodiments, a hierarchical access control linkage mechanism is configured between the intelligent main control center 20 and the access control execution unit 30: when the trigger is determined to be at the physical environment level, the intelligent main control center 20 issues the highest-level emergency unlocking command to the access control execution unit 30, forcibly unlocking the door; when the trigger is determined to be at the human signal level, the intelligent main control center 20 does not issue an unlocking command, and the access control execution unit 30 remains locked and burglarproof. Thus, through a hierarchical logic judgment structure, the system can ensure both fire rescue access and indoor property safety, improving the system's security and reliability.

[0026] In other embodiments, a near-field dynamic authentication communication channel is established between the coordinated rescue robot 40 and the access control execution unit 30. When a human-triggered signal occurs, the intelligent main control center 20 generates a one-time dynamic digital key and packages the key into a control command sent to the coordinated rescue robot 40. When the coordinated rescue robot 40 moves into the near-field range of the access control execution unit 30, it initiates a near-field encrypted handshake matching. After successful matching, the access control execution unit 30 unlocks and allows the coordinated rescue robot 40 to pass. Thus, through the near-field handshake matching structure, secure access to the rescue equipment is achieved, preventing malicious intrusion.

[0027] In other specific embodiments, the system also includes an indoor monitoring device 60, and the intelligent main control hub 20 supports remote verification and secondary manual authorization: when an alarm occurs, the camera modules of the indoor monitoring device 60 and the linked rescue robot 40 are forcibly activated, and a real-time video stream is pushed to the user terminal 51 or the property control terminal 53; the access control execution unit 30 is configured to receive a one-time remote unlocking command issued by the user terminal 51 after biometric or password verification. Thus, through the remote video verification and authorization structure, accurate rescue decisions under manual intervention are achieved, avoiding the risk of blind unlocking.

[0028] In other embodiments, the distributed sensor network 10 communicates with the intelligent master control center 20 using frequency hopping spread spectrum technology and has an anti-interference disconnection early warning mechanism: the sub-transmitter node 11 sends encrypted heartbeat packets to the intelligent master control center 20 at a preset period; when the intelligent master control center 20 continuously loses heartbeat packets from any sub-transmitter node 11, it triggers a zone security alarm independent of the fire alarm and pushes suspected interference disconnection information to the user terminal 51. Thus, through the periodic heartbeat monitoring structure, real-time perception of link anomalies is achieved, enhancing the system's anti-interference capability.

[0029] In some embodiments, the intelligent main control hub 20 and all sub-transmitter nodes 11 are equipped with a dual-circuit survival power supply system 23 and a heterogeneous dual-network communication mechanism 24. The dual-circuit survival power supply system 23 includes a mains power / low-voltage DC input module 231 and a built-in rechargeable battery module 232, configured to seamlessly switch to built-in battery power supply when the external mains power fails. The heterogeneous dual-network communication mechanism 24 includes a wireless local area network module 241 and an independent cellular wide area network (WAN) module 242. When a wireless local area network disconnection is detected, the communication scheduling module 22 forcibly wakes up the WAN module 242 to send alarm information. Thus, through the redundant power supply and communication structure, emergency reliability is achieved in extreme situations of power outages and network disconnections, ensuring uninterrupted transmission of distress signals.

[0030] In other embodiments, the absolute physical coordinates embedded in the targeted rescue data packet adopt a hierarchical structured data format, specifically including: city, district, road / street, community number, building number, floor number, and precise room number. Thus, through structured spatial data packets, precise location of the rescue position is achieved within seconds, significantly reducing search and rescue time.

[0031] In some embodiments, the coordinated rescue robot 40 is equipped with a smoke-resistant composite sensor navigation module 41; the smoke-resistant composite sensor navigation module 41 includes an optical camera 411, a millimeter-wave radar 412, and an infrared thermal imager 413; wherein, the millimeter-wave radar 412 is used to penetrate the smoke environment for physical obstacle avoidance and spatial modeling, and the infrared thermal imager 413 is used to locate the center of the high-temperature fire source and the thermal radiation contour of personnel in blinding smoke. Thus, through a multi-dimensional composite perception structure, high-precision autonomous navigation and search and rescue target locking of the robot in a fire environment are achieved.

[0032] In other embodiments, after the coordinated rescue robot 40 reaches the designated location at absolute physical coordinates, it automatically grants its underlying motion control permissions, video pan-tilt control permissions, and fire extinguishing equipment triggering permissions to the pre-authorized user terminal 51 and fire dispatch terminal 54 via the intelligent main control hub 20 or cloud dispatch platform. Thus, through this remote access control structure, flexible takeover of on-site rescue operations is achieved, effectively improving the efficiency of handling complex fire situations.

[0033] The specific principle and usage method of a fire rescue linkage system provided in this embodiment are as follows: Normally, the microprocessor 21 in the sub-transmitter node 11 periodically sends encrypted heartbeat packets to the intelligent main control center 20 through a timed wake-up circuit to maintain the system's health self-check.

[0034] When a fire occurs, the temperature sensor 111 or physical button 112 in the sub-transmitter node 11 triggers an interrupt, or the sound pickup module 113 collects a specific voiceprint, and the system immediately switches to the trigger working mode. The intelligent main control center 20 receives the signal and triggers the fire hazard multimodal joint judgment logic, quickly generating a targeted rescue data packet containing precise city, road section, building and room number. The communication dispatch module 22 concurrently makes outbound calls and pushes text messages to user terminal 51, neighbor terminal 52 and other level terminals 50.

[0035] Simultaneously, the intelligent main control center 20 sends linkage commands to the access control execution unit 30 and the linkage rescue robot 40. If the trigger is a physical environment-level event, the access control execution unit 30 directly unlocks; if the trigger is a human signal-level event, the linkage rescue robot 40 arrives at the scene and completes near-field dynamic authentication with the access control execution unit 30. The linkage rescue robot 40 uses the anti-smoke composite sensor navigation module 41 and the mid-infrared thermal imager 413 to locate the fire source, transmits real-time images back to the user terminal 51 through the optical camera 411, and grants control permissions, allowing authorized personnel to remotely control the moving chassis and fire extinguishing actuators through the user terminal 51 for firefighting and rescue operations.
