Description

Technical Field

[0001] This invention relates to the field of communication assurance technology, specifically to a multi-functional cascaded multi-network converged communication assurance system. Background Technology

[0002] In urban fire rescue operations, handling fires in complex scenarios such as high-rise buildings and underground spaces poses extremely severe challenges to the breadth of communication coverage, transmission stability, and uninterrupted operation. However, existing technologies have a series of obvious shortcomings, seriously limiting rescue efficiency and personnel safety.

[0003] Currently, fire communication relies heavily on single wireless transmission methods, such as walkie-talkies and wireless image transmission equipment in the 350MHz or 400MHz bands. These are highly susceptible to interference from reinforced concrete and metal shielding in building structures, leading to rapid signal attenuation, limited transmission distance (usually less than 100 meters), and frequent communication interruptions. Furthermore, traditional communication cables only support data transmission between endpoints; signal access and forwarding are impossible in the middle sections of the cable path, creating coverage blind spots. Firefighters frequently face difficulties with intermittent signals and disrupted command and dispatch when reaching the scene. Existing communication systems also struggle to be compatible with multiple frequency bands. For example, 400MHz walkie-talkie signals and 2.4GHz or 5.8GHz WiFi signals cannot be transmitted concurrently in the same system, thus failing to support the real-time transmission needs of multiple types of data, such as voice, video, images, location data, and vital signs data.

[0004] Regarding directional lighting, existing systems are functionally limited, providing only basic guidance and unable to coordinate with communication systems or dynamically adjust lighting status or path information based on instructions. Their power supply relies heavily on independent power sources, resulting in short battery life and an inability to power repeaters, positioning modules, and other equipment along the route, severely impacting system reliability during extended missions. Furthermore, existing firefighting equipment is functionally dispersed, requiring firefighters to carry multiple devices simultaneously, including communication, lighting, and directional equipment. This not only increases weight but also reduces operational convenience and response efficiency, failing to meet the integrated, collaborative, and reliable requirements of modern rescue operations. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-functional cascaded multi-network converged communication support system, which improves fire rescue efficiency and personal safety through wired and wireless multi-mode converged communication, broadband leaky cable transmission technology and integrated design, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional cascaded multi-network converged communication support system, comprising a central control console, multiple sets of leaky cable communication and rescue lighting lines, and multiple sets of cable reels; one end of the central control console is cascaded with multiple cable reels in sequence via leaky cable communication and rescue lighting lines, and adjacent cable reels are cascaded and expanded through leaky cable communication and rescue lighting lines;

[0007] The central control unit integrates a signal processing module, a multi-band signal access module, a power supply management module, and a monitoring and interaction module.

[0008] The cable reel includes a winch body, a processor, a lithium battery, a repeater module, a UWB positioning module, a lighting module, an antenna module, an output module, and multiple interfaces.

[0009] The leaky coaxial cable for communication and rescue lighting is an integrated cable with a transparent outer sheath. Internally, it integrates a leaky coaxial cable, an EL cold light core wire, a power supply cable, and a steel cable, forming an inseparable collaborative relationship during use. The leaky coaxial cable transmits and evenly leaks communication signals along the line. The EL cold light core wire serves as a visual marker for the communication path while transmitting lighting. The steel cable provides load-bearing and rescue traction functions and acts as a fixed support for the power supply cable, which continuously supplies power to the repeater modules and lighting modules along the line. The communication leaky core wire of the leaky coaxial cable for communication and rescue lighting is designed with a wide frequency band to transmit and evenly leak multiple frequency band communication signals to meet the access needs of various types of terminals.

[0010] Preferably, the winch body of the coil is equipped with a winch handle and a carrying handle, and a switch button is provided on the side, which can independently control the start and stop of the coil's lighting and communication relay functions; the processor communicates with the signal processing module of the central control console and the processors of adjacent coils, and can feed back the coil's power and signal strength status to the central control console; when the external power supply is interrupted, the lithium battery can temporarily power the coil's own module and small equipment along the line.

[0011] Preferably, the repeater module of the cable reel is used to enhance the signal strength of the leaky cable transmission; the UWB positioning module can collect the cable reel's position information and transmit it back to the central control console and monitoring platform; the lighting module includes a high-intensity lamp that can provide high-brightness illumination and can be linked with the communication system to adjust the lighting area; the antenna module is used to receive and transmit wireless signals, enhancing the wireless connectivity between the cable reel and surrounding communication devices.

[0012] Preferably, the output module of the cable reel includes a 12V power supply port, a 24V power supply port, a USB interface, and two cable cascading connectors; the 12V power supply port and the 24V power supply port can be connected to external devices that require power; the USB interface supports charging of small devices; the two cable cascading connectors are used to connect the leaky cable communication and rescue lighting lines of adjacent cable reels to realize system cascading expansion.

[0013] Preferably, the communication leaky cable core of the leaky cable communication rescue lighting line adopts a wideband design. This wideband design establishes unified leakage control rules, assigning differentiated leakage weights to different frequency signals along a single transmission path, achieving cross-band coordinated diffusion and dynamic balanced coverage. This rule breaks through the passive leakage method of relying solely on uniform slotting in the physical structure of the leaky cable; instead, it uses a logical-level leakage control mechanism to enable high-frequency and low-frequency signals to produce complementary effects in the same channel. For example, in underground fire rescue scenarios, 2.4GHz or 5.8GHz high-frequency WiFi signals typically attenuate too quickly, resulting in limited coverage distance, while 350MHz or 400MHz low-frequency walkie-talkie signals, although able to propagate further, struggle to guarantee uniform coverage at every location along the route. By pre-setting the leakage weights of each frequency band along the transmission path using unified leakage control rules, such as increasing the leakage ratio of high-frequency signals to ensure near-end coverage, the design achieves better coverage. The design achieves stable coverage while reducing low-frequency signal leakage to extend the propagation capability at distant points, thus realizing a cooperative diffusion mode with uniform coverage along the entire path. Through the complementary characteristics of cross-frequency bands, this design avoids interference due to excessively strong signals or interruptions due to excessively weak signals in certain sections, ensuring continuous and reliable access for various types of terminals, such as WiFi devices, walkie-talkies, UWB positioning terminals, and LoRa sensors, even in complex environments. This wideband design solves the problem of uneven leakage under multi-frequency band coexistence conditions and proposes a dynamic control mechanism for frequency-related leakage weights, enabling leaky cable communication to achieve full-frequency compatibility, uniform coverage across the entire path, and reliable coverage in complex rescue environments. The power supply conductor is made of wear-resistant and high-temperature resistant material, capable of carrying 12V / 24V voltage transmission. The lighting cable connects to the lighting module on the cable reel, forming a continuous directional lighting link. The lighting module can adjust its brightness or switch flashing modes according to communication system commands.

[0014] Preferably, the communication support system is connected to a portable satellite station for establishing a communication link relay service with the command center in areas without ground signal coverage.

[0015] Preferably, the signal processing module of the central control unit is used to decode, modulate, and forward the received 433MHz LORA signal, 350MHz / 400MHz walkie-talkie signal, and 2.4GHz / 5.8GHz WiFi signal; the multi-band signal device access module supports the access of LORA self-organizing network devices, walkie-talkies, WiFi devices, positioning terminals, thermal imaging devices, and image transmission devices; the power supply management module has dual power supply modes of external power supply and internal backup lithium battery pack, and can provide 12V / 24V compatible power supply through the leaky cable communication and rescue lighting line, and supports USB interface power supply; the monitoring and interaction module is connected to the command center server, monitoring platform, and forward command terminal, and can display the position of the cable reel, communication signal strength, lighting status, and equipment power supply status, and supports command issuance and data feedback.

[0016] Preferably, the central control console can also be connected to a command center server, which is used to store data such as video, location, and vital signs during the rescue process, and to realize data visualization and analysis through a monitoring platform.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This multi-functional cascaded multi-network converged communication support system, by adopting wired and wireless multi-mode converged communication technology, broadband leaky cable transmission technology and integrated design, solves the problems of communication coverage, multi-service data transmission, directional lighting and power supply coordination in confined and complex environments, ensures smooth communication of various equipment for firefighters, achieves unimpeded communication, and thus improves fire rescue efficiency and the safety of firefighters.

[0019] 2. This multi-functional cascaded multi-network converged communication support system uses the signal processing module of the central control console to uniformly decode, modulate, and forward multi-frequency signals. It can simultaneously carry the concurrent transmission of multiple types of service data, such as positioning data, vital sign data, on-site video, images, and voice. Compared with existing communication systems that are difficult to be compatible with multiple frequency bands and multiple services, it can provide the command center with comprehensive and real-time on-site information support, helping commanders to accurately judge the rescue situation, formulate scientific dispatch plans, and improve the efficiency of rescue decision-making.

[0020] 3. In this multi-functional cascaded multi-network integrated communication support system, the lighting cable of the leaky cable communication rescue lighting line is connected to the lighting module of the cable reel to form a continuous guide lighting link. The lighting module can receive commands from the central control console through the communication system to flexibly adjust the brightness or switch the flashing mode.

[0021] 4. This multi-functional cascaded multi-network converged communication assurance system introduces unified leakage control rules into broadband leaky cables and sets differentiated leakage weights for signals of different frequencies. This achieves complementary diffusion of rapid attenuation of high-frequency signals and long-distance propagation of low-frequency signals, thereby solving the problem of uneven local coverage caused by independent leakage in multiple frequency bands. This makes the signal distribution more balanced throughout the entire path range, thus ensuring continuous access and stable communication for multiple types of terminals in complex environments, and improving the coverage continuity and overall reliability of the system.

[0030] Please see Figures 1-5 The present invention provides a technical solution: a multi-functional cascaded multi-network converged communication support system, including a central control console, multiple sets of leaky cable communication and rescue lighting lines and multiple sets of cable reels; one end of the central control console is cascaded with multiple cable reels in sequence through leaky cable communication and rescue lighting lines, and adjacent cable reels are cascaded and expanded through leaky cable communication and rescue lighting lines;

[0031] The central control unit integrates a signal processing module, a multi-band signal access module, a power supply management module, and a monitoring and interaction module;

[0032] The central control unit's signal processing module decodes, modulates, and forwards received 433MHz LORA signals, 350MHz / 400MHz walkie-talkie signals, and 2.4GHz / 5.8GHz WiFi signals. The multi-band signal access module supports LORA self-organizing network devices, walkie-talkies, WiFi devices, positioning terminals, thermal imaging devices, and image transmission devices. The power management module features dual power supply modes: external power and internal backup lithium battery packs. It can provide 12V / 24V power via leaky cable communication and rescue lighting lines and supports USB power supply. The monitoring and interaction module connects to the command center server, monitoring platform, and forward command terminal, displaying cable reel position, communication signal strength, lighting status, and equipment power supply status. It also supports command issuance and data feedback. The central control unit can also connect to the command center server, which stores video, location, and vital signs data during the rescue process and enables data visualization and analysis through the monitoring platform.

[0033] The cable reel includes the winch body, processor, lithium battery, repeater module, UWB positioning module, lighting module, antenna module, output module and multiple interfaces.

[0034] The winch body of the reel is equipped with a winch handle and a carrying handle, and a switch button is located on the side, which can independently control the start and stop of the reel's lighting and communication relay functions; the processor communicates with the signal processing module of the central control panel and the processors of adjacent reels, and can feed back the reel's power and signal strength status to the central control panel; when the external power supply is interrupted, the lithium battery can temporarily power the reel's own module and small equipment along the line.

[0035] The repeater module of the cable reel is used to enhance the signal strength of the leaky cable transmission; the UWB positioning module can collect the position information of the cable reel and transmit it back to the central control console and monitoring platform; the lighting module includes a high-intensity lamp, which can provide high-brightness lighting and can be linked with the communication system to adjust the lighting area; the antenna module is used to receive and transmit wireless signals, enhancing the wireless connectivity between the cable reel and surrounding communication equipment.

[0036] The output module of the cable reel includes a 12V power supply port, a 24V power supply port, a USB interface, and two cable cascading connectors; the 12V and 24V power supply ports can be connected to external devices that require power; the USB interface supports charging of small devices; the two cable cascading connectors are used to connect the leaky cable communication and rescue lighting lines of adjacent cable reels to achieve system cascading expansion.

[0037] The leaky cable communication and rescue lighting line is an integrated cable. The outer part is a sheathed cable, and the inside contains a broadband leaky cable, an EL cold light core wire, a steel cable, and a power supply cable.

[0038] Please see Figure 5 The communication leaky cable core wire integrated within the leaky cable communication and rescue lighting line adopts a wideband design. This design establishes unified leakage control rules, setting differentiated leakage weights for different frequency signals within a single transmission path. This causes the signals to gradually attenuate and leak along the propagation path according to a preset ratio, thereby achieving continuous coverage and coordinated diffusion of multi-frequency signals. Unlike existing technologies that rely on physical slotting structures in the leaky cable to achieve passive leakage at a single frequency, this design uses a logic-level leakage control mechanism to dynamically adjust high-frequency and low-frequency signals along the same physical path, making their coverage performance complementary. For example, when high-frequency WiFi signals of 2.4GHz or 5.8GHz are prone to rapid attenuation, the leakage ratio of high-frequency signals at the near end is increased to ensure stable communication over short distances. Simultaneously, when low-frequency walkie-talkie signals of 350MHz or 400MHz are prone to long-distance propagation but have insufficient near-end leakage, their leakage is reduced. The weighting extends the propagation capability, thereby achieving a balanced distribution of signal strength throughout the entire path. This design effectively avoids signal interference caused by excessively strong local signals or communication interruptions caused by excessively weak signals, enabling signals from different frequency bands to form coordinated coverage in complex fire rescue environments, ensuring continuous access for various types of terminals, such as walkie-talkies, WiFi devices, UWB positioning terminals, and LoRa sensors. This wideband design proposes a dynamic control mechanism for frequency-related leakage weights, enabling leaky cable communication to overcome the limitations of uniform leakage in traditional physical structures, achieving full-frequency compatibility, uniform coverage across the entire segment, and reliable coverage throughout the entire area, demonstrating technological advancements in extreme environments such as complex building structures and underground spaces. The power supply conductor is made of wear-resistant and high-temperature resistant material, capable of carrying 12V / 24V voltage transmission. The lighting cable connects to the lighting module on the cable reel, forming a continuous directional lighting link. The lighting module can adjust its brightness or switch flashing modes according to the communication system commands.

[0039] The communication support system also includes establishing communication with a satellite portable station, which connects to the central control station in areas without ground signal coverage, providing communication link relay services between the system and the command center.

[0040] Multimode converged communication system:

[0041] Wideband leaky cable transmission: It uses a specially designed leaky cable as the backbone transmission medium, supporting full-band signal transmission such as 350MHz, 370MHz, 400MHz, 433MHz, 800MHz, 2.4GHz, 2.6GHz, 3.5GHz, and 5.8GHz. The outer layer of the leaky cable has a periodic slot structure to achieve uniform signal radiation along the entire length of the cable, with a coverage radius of ≥2 meters.

[0042] Wired and wireless collaboration: Leaky cable serves as the main communication link, ensuring continuous coverage along the laying path. Each cable reel and winch integrates a repeater (operating frequency band matched with the leaky cable) to achieve seamless connection between wireless signals (radius ≥ 20 meters) and wired leaky cable, forming a hybrid network architecture of wired backbone + wireless extension.

[0043] Multi-service data processing: The system adopts software-defined radio (SDR) technology and uses the baseband processing unit to perform protocol conversion and priority scheduling on positioning data (such as UWB / BeiDou / GPS fusion), vital signs data (heart rate, blood oxygen, body temperature, etc.), video data, image data, and voice data to ensure that the latency of critical services (such as vital signs) is ≤3s.

[0044] Guide lighting system:

[0045] Intelligent guidance control: The communication lighting cable has a built-in light-emitting cable. Through commands issued from the central control console, the color (yellow and green), brightness (0-100% stepless adjustment), and flashing frequency (1-5Hz) of the light strip can be dynamically controlled. For example, a solid green light indicates a safety passage, while a gradient yellow light guides the evacuation direction.

[0046] Emergency lighting modes: Each cable reel and winch is equipped with three modes: high-brightness LED, SOS flashing (internationally recognized Morse code), and a battery life of ≥6 hours (lithium battery powered) or continuous power supply (external power supply, with a power supply cable in the cable).

[0047] Power supply system:

[0048] Dual power supply design: Each coil has a built-in rechargeable lithium battery and also supports cascading power supply via the built-in power cord (12V). The coil is equipped with a power management module that can intelligently switch power supply modes and monitor battery status (charge, temperature, health).

[0049] Extended power supply interface: Each winch is equipped with 2 power output interfaces (12V-24V) and 2 5V USB interfaces, which can power external devices such as walkie-talkies, individual soldier positioning terminals, vital signs monitors, and lighting.

[0050] Multi-point cascade system:

[0051] Physical interface design: The cable reel is equipped with waterproof multi-purpose interfaces at both ends, integrating data transmission (wideband leaky cable), power supply (12V / 24V), and lighting control circuits, and supports hot-swapping and automatic protocol identification.

[0052] Cascading Topology: The system supports various topologies such as tree and ring, with a single link capable of cascading up to 10 cable reels (total length ≤ 500 meters), and communication latency between adjacent reels ≤ 3 seconds. Automatic link discovery, fault diagnosis, and redundancy backup are achieved through a distributed self-organizing network protocol.

[0053] Positioning and alarm system:

[0054] UWB Precise Positioning: Each cable reel and winch integrates a UWB positioning base station (positioning accuracy ±0.5 meters), forming an indoor positioning network with the individual positioning terminals worn by firefighters (integrating UWB modules, air pressure detection modules, etc.). Combined with outdoor positioning such as BeiDou / GPS, seamless positioning coverage is achieved across all scenarios.

[0055] Intelligent alarm mechanism: The system supports three alarm triggering methods, and the alarm threshold conditions can be configured: manual alarm via SOS button; alarm for abnormal vital signs, heart rate > 180 beats / min or blood oxygen < 90%; environmental parameter alarm, monitored by external sensors for temperature > 60℃ and smoke concentration > 1000ppm. Alarm information is provided through three methods: sound and light (winch light strip flashes red), voice (winch and cable reel amplification system), and flashing of the winch and cable lights.

[0056] Public address system:

[0057] Each winch is equipped with a waterproof speaker with a power of 5W and a frequency response of 80Hz-16kHz, supporting two-way voice communication. The central control panel can issue voice commands (clarity ≥95%) and simultaneously monitor the ambient sound in real time (pickup distance ≥1 meter).

[0058] System deployment process:

[0059] Preliminary preparations: Determine the required number of cable reels based on the rescue scenario (such as underground parking garage fire, high-rise office building fire), check the status of the central control console, leaky cable communication and rescue lighting lines, and cable reels, and ensure that the lithium battery is fully charged, the cables are undamaged, and all interfaces are properly connected.

[0060] Central control console setup: Deploy the central control console on the ground floor or in an area with normal signal. Connect the central control console to the satellite portable station (if there is no ground signal on site) and the command center server via wired or wireless means to complete the communication pairing between the monitoring platform and the central control console, ensuring that the command center can receive the data transmitted by the central control console in real time.

[0061] Cable Reel Cascading and Laying: Firefighters carry cable reels into the rescue area (such as underground spaces). First, they connect the first reel to the control center via a leaky cable communication and rescue lighting line. Then, according to the direction of the rescue, subsequent reels are connected to the previous reel via cable cascading connectors, and the leaky cable communication and rescue lighting line is deployed. During laying, the reels can be easily moved using their handles, and the cable length can be adjusted using the winch handle to ensure the cable is laid flat and tangle-free.

[0062] Equipment connection and debugging: Connect the equipment needed for the internal attack (such as walkie-talkies, individual soldier positioning terminals, image transmission equipment, etc.) to the system respectively. Check the communication status and data transmission of each device through the monitoring and interaction module of the central control console, and debug the brightness and mode of the lighting module to ensure that all functions of the system are running normally.

[0063] Working principle: Data generated by field equipment is received via antenna modules or cables on the cable reel, processed by a processor, amplified by repeater modules, and then transmitted to the central control station via the communication leaky cable core wire of the life-saving lighting line. The central control station processes the multi-frequency signals uniformly, forwarding them to other cable reels and related equipment for collaborative field communication, and simultaneously transmitting them to the command center via satellite portable stations or terrestrial networks to ensure real-time monitoring of the field situation. At the same time, commands from the command center can be transmitted back to various field devices, achieving two-way communication.

[0064] After the system starts, the lighting modules on the cable reels automatically turn on, forming a continuous directional lighting path. When the communication system detects a change in the path, the central control console can send instructions to the corresponding cable reels to adjust the brightness of the lighting modules or switch to a flashing warning mode to guide firefighters away from dangerous areas. In addition, firefighters can also independently control the lighting through the switch buttons on the cable reels to meet their local lighting needs.

[0065] The system prioritizes external power supply, such as power supply to the command center and on-site emergency power supply, and supplies power to the cable reel and equipment along the line through the central control console and the leaky cable communication and rescue lighting line. When the external power supply is interrupted, the lithium battery of the cable reel automatically switches to power supply mode to ensure the normal operation of key equipment such as repeaters, positioning modules, and lighting modules. At the same time, it provides emergency charging for small devices such as walkie-talkies through the USB interface to extend the equipment's usage time.
