Description

Technical Field

[0001] This invention relates to the field of emergency rescue communication technology, specifically to a multi-source communication command system for complex disaster scenarios and its usage method. Background Technology

[0002] In complex disaster scenarios such as floods, typhoons, earthquakes, and mine collapses, emergency rescue faces numerous challenges. On-site rescue points are numerous and widespread, and time is of the essence. Power outages can easily paralyze external communications, making it impossible to transmit disaster information in a timely manner. Different brands and models of disaster data collection equipment have poor compatibility, making it difficult to connect to a unified emergency system for data transmission. The dispatch of rescue materials relies on experience, resulting in low efficiency. Existing emergency communication systems mostly rely on fixed base stations, which are difficult to deploy in scenarios without power, network, or roads. Furthermore, they suffer from poor network scalability and severe bandwidth loss, failing to meet the needs of high-definition audio and video transmission and multi-device collaboration.

[0003] While integrated communication networks have become a research hotspot in the current technology, they mostly adopt centralized base station designs or simple relay modes, which have problems such as zero two-hop bandwidth and inability to be commercially viable. Mesh network technology is limited by co-frequency interconnection, and the increase in the number of nodes can easily lead to a surge in network resource consumption. In actual use, the number of hops usually does not exceed three levels, and it cannot directly connect to standard wireless devices. Although foreign related systems have more complete functions, they lack the mobility to adapt to complex disaster scenarios and are subject to technical blockades and compatibility issues.

[0004] Therefore, there is an urgent need for a communication command system and its usage method that can adapt to complex disaster scenarios, be rapidly deployed, be compatible with multiple sources of equipment, and provide highly reliable transmission. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-source communication command system and its usage method for complex disaster scenarios. It has the advantages of solving the technical problems of slow deployment, communication paralysis, poor equipment compatibility, insufficient network scalability, and low scheduling efficiency of existing emergency communication command systems in complex disaster scenarios, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-source communication command system for complex disaster scenarios, comprising a system body, wherein the system body includes a mobile emergency carrier module, a high-bandwidth, low-latency self-organizing network module, a multi-source communication conversion module, a microservice integration module, an intelligent scheduling and analysis module, and an emergency response module.

[0007] The mobile emergency carrier module is a modular and mobile integrated structure adapted to complex disaster scenarios such as mines, tunnels, floods, and earthquakes. It integrates communication infrastructure equipment, individual intelligent equipment, and mobile power supply equipment. The core of the communication infrastructure equipment is the ZT12-F intrinsically safe wireless self-organizing network base station for mining. The individual intelligent equipment includes an intrinsically safe mobile phone for mining, an intrinsically safe information mine lamp, and an intrinsically safe audio and video recorder for mining. The mobile power supply equipment is a mine-sealed and intrinsically safe power supply. The high-bandwidth, low-latency self-organizing network module, built on STRONGLINK core technology, is used to achieve high-speed wireless intelligent networking and multi-point full coverage of rescue areas. It supports stable multi-hop connections of 14 points or more, with a single link bandwidth of no less than 400 Mbps. The switching latency between the public network and the self-organizing network is ≤1 second, close to the 5G second-to-second switching speed. It also has network self-healing capabilities. When a single link is interrupted, it can automatically detect the fault and switch to the backup link with a self-healing time of ≤3 seconds. It avoids communication interruption through a virtual multipath transmission mechanism, adapting to the emergency rescue needs that combine peacetime and wartime needs. At the same time, it supports integrated functions of high-speed wireless intelligent networking, emergency broadcasting, emergency lighting, and location backhaul.

[0008] The multi-source communication conversion module has a built-in multi-protocol compatible gateway, which supports unified parsing and conversion of multiple protocols. It is compatible with heterogeneous devices of different brands and models, such as intrinsically safe cameras, intrinsically safe gas detectors, mining information lamps, and intercom terminals. It also supports hot-swappable access and automatic protocol adaptation for heterogeneous devices.

[0009] The microservice integration module adopts a virtualized service BS architecture, divided from top to bottom into a perception layer, a data storage layer, a data processing layer, an application layer, and an end-user layer. Each layer interacts with data through standardized interfaces. The perception layer consists of communication equipment, audio and video acquisition equipment, gas monitoring equipment, and sensing terminals connected to the network link, responsible for on-site data acquisition. The data storage layer adopts a storage strategy combining distributed caching and centralized databases. Frequently accessed hot data is stored through distributed caching, while high-concurrency data is processed asynchronously and authorized to improve processing efficiency. It supports mainstream databases such as MySQL and Redis, and sensitive data is stored using highly encrypted methods. The data processing layer has batch processing and real-time processing capabilities, generating multi-dimensional query results through statistical analysis and unstructured data analysis to support the application layer. The application layer implements functions such as multi-module, multi-source data fusion display, integrated communication, video surveillance, image transmission and recording, and system management. The overall architecture supports microservice expansion and can achieve non-stop upgrades and multi-version operation.

[0010] The intelligent scheduling and analysis module integrates a GIS geographic information system, multi-scenario disaster simulation algorithms, and dynamic disaster avoidance route planning units. It can integrate meteorological data, terrain data, real-time disaster data, equipment operation status data, and rescue force distribution data to achieve collaborative consultation, intelligent scheduling, and risk assessment.

[0011] The emergency response module works in conjunction with the intelligent dispatch and analysis module to receive dispatch instructions and trigger corresponding rescue actions. It supports real-time duplex intercom, high-definition video calls, emergency broadcasts, over-limit alarm prompts, photo uploads, and video feedback functions. Among these, video calls can be linked to display the real-time images from the terminal's associated camera, and video feedback supports simultaneous real-time display of multiple wireless audio and video images. Photo upload data is automatically stored on the server and associated with event descriptions and upload identifiers for easy subsequent tracing and analysis, ensuring accurate implementation of command instructions and comprehensive feedback of on-site information.

[0012] Furthermore, as a preferred embodiment of the present invention, the mobile emergency carrier module includes a mine-use encapsulation and intrinsically safe power supply, a portable three-screen display, and a ZT12-F mine-use intrinsically safe wireless self-organizing network base station. The base station is equipped with three Ethernet ports, one optical interface, one RS485 interface, and four WIFI antennas. The maximum transmission distance of the optical interface is not less than 20km, and the unobstructed WIFI communication distance is 0 to 400m.

[0013] Furthermore, as a preferred embodiment of the present invention, the multi-source communication conversion module supports audio and video encoding and compression in G.711, G.729, and G.723 formats. After converting audio and video data, environmental monitoring data, and equipment control commands into data packets via TCP / IP protocol, they are transmitted via SIP, SDP, and RTP protocols, enabling 200 mobile communication terminals to be online concurrently and 500 remote video monitoring terminals to access simultaneously.

[0014] Furthermore, as a preferred embodiment of the present invention, the intelligent scheduling and analysis module has scheduling functions such as one-to-one calling, forced insertion, forced disconnection, and all-calling. It supports 24-hour call recording and video synchronous backup, and can receive carbon monoxide, methane, oxygen concentration and temperature data uploaded by mining gas detectors in real time. When the detected data exceeds the limit, it automatically triggers a graded alarm and quickly generates the optimal disaster avoidance route based on the GIS geographic information system, and pushes it to the front-line individual intelligent equipment.

[0015] The present invention discloses a method for using a multi-source communication command system in complex disaster scenarios, comprising the following steps: S1: Based on the disaster scenario type and rescue area scope, rapidly deploy a layered distributed system. In the ground control room, activate high-performance emergency rescue laptops and portable three-screen monitors. After powering on, start the system program with one click and connect to the ground industrial ring network via a ground industrial switch. Within 3 minutes, initialize the command terminal's data reception, command issuance, and visual monitoring functions. Deploy ZT12-F intrinsically safe wireless self-organizing network base stations in key areas of the disaster site. Powered by a mining-grade encapsulated and intrinsically safe power supply with a rated operating voltage of DC9-12V and a maximum operating current ≤1000mA. The base stations connect to the underground industrial ring network via an underground industrial switch or directly establish a connection with the ground command center via a wireless link. This is accompanied by 1-2 on-site liaison personnel carrying intrinsically safe mining mobile phones and intrinsically safe mining lamps. Deploy core nodes within 4 minutes, deploying them every 200-300 meters along the rescue route. One ZT12-F intrinsically safe wireless self-organizing network base station is deployed per meter. The base stations are interconnected through the wireless self-organizing network to form a continuous communication link. The supporting intrinsically safe power supply ensures continuous power supply. Rescue personnel carry intrinsically safe audio and video recorders and intrinsically safe wireless gas detectors to achieve real-time data collection on site. The deployment time per kilometer is ≤5 minutes. In special scenarios such as fully mechanized mining faces and areas where hazardous gases are prone to accumulate, no less than two intrinsically safe wireless cameras are deployed for every 2000 meters of rescue area. Long-distance video transmission is achieved through optical interfaces with a working wavelength of 1310nm and a transmission rate of 1000Mbps. During deployment, ensure that the four WIFI antennas of the base station are unobstructed to ensure a communication distance of 0 to 400m. The entire deployment process does not require manual configuration of network parameters. After the equipment is deployed, the network initialization is automatically completed. The total deployment time is ≤5 minutes per square kilometer of rescue area. S2: The high-bandwidth, low-latency self-organizing network module automatically initiates the networking process based on STRONGLINK technology. Each ZT12-F mine-use intrinsically safe wireless self-organizing network base station automatically scans for available nodes in the vicinity through WIFI antennas covering the center frequencies of 2.400±0.080GHz and 5.800±0.025GHz, and completes the establishment of wireless links within 10 seconds, forming a mobile emergency communication network that supports 14 or more multi-hop connections and a single link bandwidth of ≥400 Mbps. It adopts a virtual multipath transmission mechanism to plan redundant transmission links for key data such as audio, video, and alarm information. At the same time, it reduces co-channel interference between adjacent base stations through interference control algorithms to ensure network transmission stability. It automatically completes the seamless switching parameter configuration between the public network and the self-organizing network with a switching latency of ≤1 second. When the public network is available, it prioritizes the transmission of non-emergency data. After the public network is interrupted, it immediately switches to the self-organizing network to ensure that emergency command data is not interrupted. Information on network link connectivity, bandwidth utilization, and device online status is fed back to the ground command center in real time and displayed visually through the system management interface. Alarm prompts are automatically triggered in abnormal situations such as base station offline and insufficient bandwidth. S3: Achieves fully compatible access for heterogeneous devices through a multi-source communication conversion module. After the intrinsically safe mining mobile phones, intrinsically safe mining cameras, intrinsically safe mining audio and video recorders, intrinsically safe mining wireless gas detectors, and intrinsically safe mining information lamps are powered on, they automatically send access requests to the multi-source communication conversion module through a multi-protocol gateway. After receiving the request, the multi-source communication conversion module completes protocol parsing and adaptation within 10 seconds, encodes and compresses the heterogeneous device data using G.711, G.729, and G.723 formats for audio and video encoding, encapsulates it into system standard data packets using the TCP / IP protocol, and assigns a unique device identifier. It establishes a dedicated communication link for the accessed devices, supports hot-swappable access, and does not affect the operation of the existing network when new devices are added or old devices are removed. At the same time, it ensures the security of data transmission between the devices and the command center through encryption protocols. The system monitors the battery level, signal strength, and data integrity of the accessed devices in real time. When the device has low battery, weak signal, or abnormal data transmission, it sends reminder information to the ground command center and the personnel carrying the equipment. S4: Real-time acquisition, processing, and secure transmission of multi-source data. Sensing layer devices acquire data at preset frequencies. Among them, the intrinsically safe wireless gas detector for mining acquires carbon monoxide, methane, oxygen concentration, and temperature data at a frequency of ≥1 time per second. The intrinsically safe wireless camera and audio / video recorder for mining acquire 4K resolution audio / video data at a frame rate of ≥30 frames per second. The intrinsically safe mobile phone and information mine lamp for mining acquire personnel location and voice command data. After the acquired data is transmitted to the data processing layer, it is processed in real time through statistical analysis and unstructured data analysis technology to remove abnormal data and compress redundant information. Audio and video data adopts multi-path caching and dedicated line communication technology to reduce transmission latency and ensure that 4K video stream transmission with a low latency of ≤300ms can be achieved under certain network conditions. The processed data is classified and stored in the data storage layer. High-frequency access hot data adopts distributed cache storage, sensitive data adopts high encryption storage method, and historical data is stored in the database to support long-term traceability. When the network is briefly interrupted, the device automatically caches the data that has not been transmitted. After the network is restored, the data retransmission mechanism is used to resume the transmission and ensure that the data is not lost. S5: Based on multi-source data fusion, it achieves precise command and collaborative operations. The intelligent dispatch and analysis module integrates meteorological data, terrain data, real-time disaster data, equipment operation status data, and rescue force distribution data. It generates a 3D map of the rescue area through a GIS geographic information system. Combined with multi-scenario disaster simulation algorithms such as mine collapse, gas leak, and flood entrapment, it simulates the development trend of disasters. The system automatically assesses surrounding risks and hazards. Based on disaster simulation results and real-time monitoring data, it generates the optimal disaster avoidance route and rescue plan within 5 seconds and pushes it to the ground command center. At the same time, it supports remote access and collaborative consultation by experts to provide professional decision-making suggestions. Commanders can perform one-to-one calls, forced insertions, forced disconnections, and all-call dispatch operations through the converged communication system. Instructions are transmitted to the front-line terminal in real time through the RTP protocol. It supports multiple instruction formats such as voice, text, and video. The system automatically records all dispatch instructions, call recordings, video consultation content, and data transmission logs. It stores them by timestamp and backs them up synchronously 24 hours a day to facilitate subsequent rescue review and accountability. S6: Ensuring precise execution of rescue operations and continuous stable system operation. Frontline rescue personnel receive command instructions and carry out rescue operations as required through intrinsically safe mining mobile phones and information mining lamps. At the same time, they provide real-time feedback on operation progress and on-site conditions through terminals, forming a closed loop of command, execution, and feedback. When the intrinsically safe mining wireless gas detector detects that the methane concentration is ≥1.0% or the oxygen concentration is ≤18%, the system automatically triggers a graded alarm. The alarm information is pushed simultaneously through multiple methods such as emergency broadcasts, terminal pop-ups, and voice prompts. When base station link interruption or equipment failure occurs, the system quickly identifies the faulty node, switches to the backup communication link based on the virtual multipath mechanism, and restores data transmission. The entire fault self-healing process takes ≤3 seconds, ensuring that the command link is not interrupted. According to the progress of rescue and changes in the on-site environment, the system dynamically adjusts the network coverage, the number of connected devices, and the scheduling priority to adapt to the dynamic changes in complex disaster scenarios and ensure continuous and stable operation in environments without electricity, network, or roads.

[0016] Furthermore, as a preferred embodiment of the present invention, in step S1, the deployment time of the mobile emergency carrier module does not exceed 5 minutes, and after the base station is deployed, it automatically establishes communication with the ground dispatch room without the need for manual configuration of network parameters.

[0017] Furthermore, as a preferred embodiment of the present invention, in step S3, the multi-source communication conversion module supports hot-swappable access of heterogeneous devices, and completes protocol adaptation and communication link establishment within 10 seconds after a new device is connected.

[0018] Furthermore, as a preferred embodiment of the present invention, in step S5, the intelligent scheduling and analysis module can automatically trigger graded alarms based on the exceeding of environmental monitoring data, and simultaneously push corresponding emergency response plans and disaster avoidance routes to frontline individual soldier intelligent equipment.

[0019] Furthermore, as a preferred embodiment of the present invention, in step S6, the network self-healing process includes three sub-steps: link fault detection, backup link switching, and data interruption resumption, with a self-healing time of no more than 3 seconds.

It eliminates the need for complex manual configuration of network parameters, enabling layered, distributed, and rapid deployment of ground command centers, key on-site nodes, rescue routes, and special areas. This completely changes the current situation of cumbersome and time-consuming deployment of emergency systems, ensuring rapid system activation and response.

[0035] The present invention discloses a method for using a multi-source communication command system in complex disaster scenarios, comprising the following steps: S1: Based on the disaster scenario type and rescue area scope, rapidly deploy a layered distributed system. In the ground control room, activate high-performance emergency rescue laptops and portable three-screen monitors. After powering on, start the system program with one click and connect to the ground industrial ring network via a ground industrial switch. Within 3 minutes, initialize the command terminal's data reception, command issuance, and visual monitoring functions. Deploy ZT12-F intrinsically safe wireless self-organizing network base stations in key areas of the disaster site. Powered by a mining-grade encapsulated and intrinsically safe power supply with a rated operating voltage of DC9-12V and a maximum operating current ≤1000mA. The base stations connect to the underground industrial ring network via an underground industrial switch or directly establish a connection with the ground command center via a wireless link. This is accompanied by 1-2 on-site liaison personnel carrying intrinsically safe mining mobile phones and intrinsically safe mining lamps. Deploy core nodes within 4 minutes, deploying them every 200-300 meters along the rescue route. One ZT12-F intrinsically safe wireless self-organizing network base station is deployed per meter. The base stations are interconnected through the wireless self-organizing network to form a continuous communication link. The supporting intrinsically safe power supply ensures continuous power supply. Rescue personnel carry intrinsically safe audio and video recorders and intrinsically safe wireless gas detectors to achieve real-time data collection on site. The deployment time per kilometer is ≤5 minutes. In special scenarios such as fully mechanized mining faces and areas where hazardous gases are prone to accumulate, no less than two intrinsically safe wireless cameras are deployed for every 2000 meters of rescue area. Long-distance video transmission is achieved through optical interfaces with a working wavelength of 1310nm and a transmission rate of 1000Mbps. During deployment, ensure that the four WIFI antennas of the base station are unobstructed to ensure a communication distance of 0 to 400m. The entire deployment process does not require manual configuration of network parameters. After the equipment is deployed, the network initialization is automatically completed. The total deployment time is ≤5 minutes per square kilometer of rescue area. S2: The high-bandwidth, low-latency self-organizing network module 3 automatically initiates the networking process based on STRONGLINK technology. Each ZT12-F mine-use intrinsically safe wireless self-organizing network base station automatically scans for available nodes in the surrounding area through WIFI antennas covering the center frequency of 2.400±0.080GHz and 5.800±0.025GHz. It completes the establishment of wireless links within 10 seconds, forming a mobile emergency communication network that supports 14 or more multi-hop connections and a single link bandwidth of ≥400 Mbps.

After the intrinsically safe mining mobile phones, intrinsically safe mining cameras, intrinsically safe mining audio and video recorders, intrinsically safe mining wireless gas detectors, and intrinsically safe mining information lamps are powered on, they automatically send access requests to the multi-source communication conversion module 4 through a multi-protocol gateway. After receiving the request, the multi-source communication conversion module 4 completes protocol parsing and adaptation within 10 seconds, encodes and compresses the heterogeneous device data using G.711, G.729, and G.723 formats for audio and video encoding, encapsulates it into system standard data packets through the TCP / IP protocol, and assigns a unique device identifier.

At the same time, the encryption protocol ensures the data transmission security between the devices and the command center. The system monitors the battery level, signal strength, and data integrity of the accessed devices in real time. When the device has low battery, weak signal, or abnormal data transmission, it sends a reminder message to the ground command center and the personnel carrying the equipment. S4: Real-time acquisition, processing, and secure transmission of multi-source data. Sensing layer devices acquire data at preset frequencies.

The intrinsically safe wireless camera and audio / video recorder for mining acquire 4K resolution audio / video data at a frame rate of ≥30 frames per second. The intrinsically safe mobile phone and information mine lamp for mining acquire personnel location and voice command data. After the acquired data is transmitted to the data processing layer, it is processed in real time through statistical analysis and unstructured data analysis technology to remove abnormal data and compress redundant information. Audio and video data adopts multi-path caching and dedicated line communication technology to reduce transmission latency and ensure that 4K video stream transmission with a low latency of ≤300ms can be achieved under certain network conditions. The processed data is classified and stored in the data storage layer. High-frequency access hot data adopts distributed cache storage, sensitive data adopts high encryption storage method, and historical data is stored in the database to support long-term traceability. When the network is briefly interrupted, the device automatically caches the data that has not been transmitted. After the network is restored, the data retransmission mechanism is used to resume the transmission and ensure that the data is not lost. S5: Based on multi-source data fusion, it achieves precise command and collaborative operations. The intelligent dispatch and analysis module 6 integrates meteorological data, terrain data, real-time disaster data, equipment operation status data, and rescue force distribution data. It generates a 3D map of the rescue area through a GIS geographic information system. Combined with multi-scenario disaster simulation algorithms such as mine collapse, gas leakage, and flood entrapment, it simulates the development trend of disasters. The system automatically assesses surrounding risks and hazards. Based on disaster simulation results and real-time monitoring data, it generates the optimal disaster avoidance route and rescue plan within 5 seconds and pushes it to the ground command center. At the same time, it supports remote access by experts for collaborative consultation and provides professional decision-making suggestions. Commanders can perform one-to-one calls, forced insertions, forced disconnections, and all-call dispatch operations through the converged communication system. Instructions are transmitted to the front-line terminal in real time through the RTP protocol. It supports multiple instruction forms such as voice, text, and video. The system automatically records all dispatch instructions, call recordings, video consultation content, and data transmission logs. It stores them by timestamp and backs them up synchronously 24 hours a day to facilitate subsequent rescue review and accountability. S6: Ensuring precise execution of rescue operations and continuous stable system operation. Frontline rescue personnel receive command instructions and carry out rescue operations as required through intrinsically safe mining mobile phones and information mining lamps. At the same time, they provide real-time feedback on operation progress and on-site conditions through terminals, forming a closed loop of command, execution, and feedback. When the intrinsically safe mining wireless gas detector detects that the methane concentration is ≥1.0% or the oxygen concentration is ≤18%, the system automatically triggers a graded alarm. The alarm information is pushed simultaneously through multiple methods such as emergency broadcasts, terminal pop-ups, and voice prompts. When base station link interruption or equipment failure occurs, the system quickly identifies the faulty node, switches to the backup communication link based on the virtual multipath mechanism, and restores data transmission. The entire fault self-healing process takes ≤3 seconds, ensuring that the command link is not interrupted. According to the progress of rescue and changes in the on-site environment, the system dynamically adjusts the network coverage, the number of connected devices, and the scheduling priority to adapt to the dynamic changes in complex disaster scenarios and ensure continuous and stable operation in environments without electricity, network, or roads.

[0036] Specifically, in step S1, the deployment time of the mobile emergency carrier module 2 is no more than 5 minutes. After the base station is deployed, it automatically establishes communication with the ground dispatch room without the need for manual configuration of network parameters.

[0037] Specifically, in step S3, the multi-source communication conversion module 4 supports hot-swappable access of heterogeneous devices, and completes protocol adaptation and communication link establishment within 10 seconds after a new device is connected.

[0038] Specifically, in step S5, the intelligent scheduling and analysis module 6 can automatically trigger tiered alarms based on the exceeding of environmental monitoring data, and simultaneously push corresponding emergency response plans and disaster avoidance routes to frontline individual soldier intelligent equipment.

[0039] Specifically, in step S6, the network self-healing process includes three sub-steps: link fault detection, backup link switching, and data interruption resumption. The self-healing time does not exceed 3 seconds.
