[0011] Figure 2 It is a principle block diagram of the present invention. DETAILED DESCRIPTION

[0012] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0013] As attached Figure 1 and Figure 2 As shown, a rescue platform for quickly building a network channel includes a communication vehicle, a drone, a backpack base station, communication equipment, a front-end video acquisition device, and a back-end monitoring and command center. In the event of a major natural disaster, front-line personnel can connect the communication vehicle, drone, backpack base station, communication equipment, front-end video acquisition equipment, and back-end monitoring and command center to the ad hoc network and quickly build a wireless ad hoc network on site. At the same time, the undamaged fixed base stations around the rescue site can also be connected to the ad hoc network to improve the wireless ad hoc network.

[0014] Among them, as attached Figure 1 and Figure 2As shown, the communication vehicle is connected to the relay satellite through signals. Specifically, the communication vehicle is equipped with satellite communication equipment, which usually includes antennas, receivers and transmitters, etc. These devices communicate directly with the relay satellite, and transmit data and voice communication through satellite signals, overcoming the limitations of the ground communication network and providing more stable and reliable communication services. In major natural disasters, the ground communication network may be damaged or interrupted. At this time, the communication vehicle can provide emergency communication services through the satellite communication system. Satellite communication has the characteristics of strong stability and wide coverage, ensuring the timely transmission of information and the smooth progress of rescue work. It is worth mentioning that the communication vehicle is also connected to the back-end monitoring and command center through signals. Specifically, the communication vehicle is equipped with a vehicle-mounted radio station. The communication vehicle is connected to the back-end monitoring and command center through the vehicle-mounted radio station. The vehicle-mounted radio station can provide longer-distance communication and can communicate with the back-end monitoring and command center and other communication vehicles. It has stronger signal penetration ability, can maintain stable communication in complex environments, and can also transmit rescue site information back to the back-end monitoring and command center as soon as possible.

[0015] As attached Figure 1 and Figure 2As shown, the drone is equipped with a micro base station, which is connected to the communication vehicle through signals, and the drone is equipped with satellite communication equipment. It can communicate well with the relay satellite when flying at high altitude, and then radiate the signals of the three major operators to the area without signal through its own micro base station. When in use, the drone is launched with a micro base station, which can further expand the wireless coverage, reduce the coverage blind area, and improve the quality of video return; the drone can also be equipped with a camera to organically combine aerial mobile monitoring with ground fixed monitoring, complement each other's advantages, form a ground-to-air "three-dimensional" monitoring network, and effectively increase the visible range of the monitoring area. Among them, the drone and the communication vehicle can be connected through the MAVLink protocol, wireless communication or satellite communication. The specific MAVLink (Micro Air Vehicle Link) protocol is a lightweight, open source communication protocol originally designed by Lorenz Meier for data exchange between micro aerial vehicles and ground control stations. The protocol uses a binary format and supports multiple message types, such as status information, command and control data, and is designed to provide efficient and reliable transmission. The design goal of the MAVLink protocol is to reduce bandwidth usage while ensuring reliable data transmission. It supports functions such as packet verification, packet loss detection and recovery, so that stable communication can be maintained even in high-interference environments. Wireless communication is one of the commonly used connection methods between drones and communication vehicles. Drones can establish connections with communication vehicles through wireless communication equipment to achieve real-time data transmission and command and dispatch. This connection method is suitable for various terrains and environments, and can ensure stable operation in complex environments such as disaster areas. Satellite communication is a means of providing stable communication in complex terrain and harsh environments. Through satellite relays, drones and communication vehicles can transmit data and command and dispatch at any location without being restricted by terrain. Satellite communication systems usually use digital communication technology, which has the advantages of long transmission distances and communication quality not being affected by distance.

[0016] As attached Figure 1 and Figure 2As shown in the figure, the backpack base station is a portable communication device, which is mainly used in emergency communication, maritime formation, rescue communication and other scenarios. It has high mobility and rapid deployment capabilities, and can respond quickly and provide communication support in extreme situations of power outage, circuit breakage and network disconnection. The backpack base station usually includes a wireless transmitter and a mobile receiver. These devices can be interconnected with the surrounding nodes through the self-organizing network protocol to achieve wireless communication. In the process, the backpack base station is used as a core communication device to interconnect with the surrounding nodes, supporting multiple communication modes, including two-way voice, image, video, data and real-time transmission of positioning information. It can be compatible with the existing communication network, provide seamless connection, and meet the diverse communication needs in rescue operations. In addition, the backpack base station can also be connected to the satellite terminal to achieve longer-distance signal transmission through satellite communication. The backpack base station is connected to the satellite backpack terminal through an Ethernet cable. The satellite backpack terminal is connected to the emergency communication backbone network using a remote relay satellite to ensure that the backpack base station is smoothly connected to the network of the main operator, so that at the rescue site, ordinary mobile phones can be directly connected to this system to achieve seamless communication with the public network. At the same time, the backpack base station is designed to be lightweight and easy for a single soldier to carry. It is usually equipped with a portable backpack that can be carried by a single person and carried by rescue workers into the rescue site. In areas without wired network coverage, multiple base stations are used for relay transmission to expand the system coverage and realize wireless interconnection and information sharing. It is worth mentioning that the backpack base station is connected to the communication vehicle through a signal. Specifically, the backpack base station is connected to the vehicle-mounted station of the communication vehicle through a wireless connection, that is, through the wireless MESH self-organizing network technology, the backpack base station and the vehicle-mounted station can automatically connect and form a network. This method does not require physical lines and is suitable for emergency communications in the field and rapid deployment in complex environments. It is convenient for backpack base stations and vehicle-mounted stations to transmit data, can realize broadband data carrying functions, and support audio and video transmission, high-definition video backhaul and other services.

[0017] As attached Figure 1 and Figure 2As shown, the rescuer also carries a communication device, which is connected to the backpack base station through a signal. The communication device includes a walkie-talkie, a satellite phone, a mobile phone and a GPS navigation device for communication services. Among them, the walkie-talkie can be a digital walkie-talkie, which is a type of upgraded traditional analog walkie-talkie and uses digital signals for communication. It has higher voice quality and anti-interference ability, supports multiple communication modes, such as group calls, single calls, text messages, etc., and can be connected to other devices through a data interface to achieve more functional expansion. However, most digital walkie-talkies do not necessarily rely on backpack base stations for communication, mainly due to their communication principles and design features. Walkie-talkies usually use point-to-point radio communication methods, converting audio signals into radio waves through a modem, and then transmitting them into the air through an antenna. The receiver's walkie-talkie receives these signals and decodes them, thereby restoring the audio signals. This direct communication method allows walkie-talkies to achieve short-distance communication without relying on external infrastructure, such as base stations. Some advanced digital walkie-talkies have built-in network functions, which can be connected to the Internet through mobile networks (4G, 5G) or Wi-Fi to achieve more diverse communication methods, such as real-time voice transmission, data sharing, etc. Specifically, a digital communication system is formed through a backpack base station and all digital walkie-talkies at the rescue site, and the signals of the digital walkie-talkies are forwarded to other base stations or directly communicated with the walkie-talkies to achieve real-time communication and data sharing. It is portable and easy to use, suitable for communication between on-site rescue personnel, and fully meets the needs of emergency communications. In addition, satellite antennas can also be installed on the walkie-talkies to send and receive signals through relay satellites to achieve satellite communication, so as to carry out long-distance communication in a network-free environment and ensure timely communication and coordination during rescue operations.

[0018] Satellite phones are devices that transmit information based on satellite communication systems. Satellite phone communication systems are mainly composed of two parts: the space part - the relay satellite and the ground part - the communication ground station. As an aerial relay station, the relay satellite is suspended high above the earth, with a wide coverage range, and can achieve long-distance wireless signal forwarding and reflection. The weak signal sent from the ground station is received by the relay satellite antenna, amplified, frequency-converted and power-amplified by the communication repeater, and then forwarded by the relay satellite to another ground station, thereby realizing communication between multiple points. Its main function is to fill the area that cannot be covered by the existing communication (wired communication, wireless communication) terminals, and ensure timely communication and coordination in rescue operations.

[0019] The communication between the mobile phone and the backpack base station is mainly based on the transmission of wireless signals, that is, electromagnetic waves, especially using microwaves as the transmission medium. These wireless signals are transmitted through media such as air to realize the information transmission between the mobile phone and the base station. Among them, the connection process between the mobile phone and the backpack base station includes the following steps: power on and network registration, connection establishment, modulation and transmission, signal propagation and reception, switching, data processing and routing, and end of communication. Specifically, when the mobile phone is turned on, it searches for and locks the base station with the strongest signal, then reads the system information broadcast by the base station, including network identification code, time, etc., and registers to the network through the identity authentication process (such as SIM card authentication). When the user initiates a call or data request, the mobile phone sends a request to the nearest base station through the control channel. The base station forwards this request to the target user or data server through the core network and allocates a dedicated communication channel. The mobile phone then modulates the data to be sent (such as voice coding, data packet) onto the allocated wireless carrier, using modulation methods (such as QAM, QPSK) to effectively utilize bandwidth and maintain signal reliability. After the signal is transmitted from the mobile phone, it propagates through the air to the base station. After the base station receives the signal, it extracts the original data through the demodulation process and uses error detection and correction technology to handle errors in transmission. During the process, when the mobile phone user moves, the signal strength and quality will change. The mobile phone will continue to monitor the signal strength of the surrounding base stations and re-establish a connection with the new best base station when necessary to ensure communication continuity. The base station then transmits the received data to the core network through a backhaul link (usually using optical fiber or microwave). The core network is responsible for further processing and routing of the data, and finally reaches the target base station or server on the Internet to complete the communication. Finally, when the call ends or the data transmission is completed, the mobile phone and the base station will release the previously allocated resources through control signaling so that they can be used by other users or communications. Mobile phones are suitable for short-distance and high-frequency communication needs. They can be used to transmit voice, data and video to meet the diverse communication needs in rescue operations.

[0020] ‌GPS navigation equipment‌ refers to equipment that uses the Global Positioning System (GPS) technology for navigation and positioning. These devices calculate the user's current position, speed and time information by receiving signals from multiple satellites. GPS navigation equipment mainly consists of the following parts: satellite part, ground control part and user equipment part. Specifically, it consists of a constellation of multiple satellites. These satellites are distributed in a specific orbit and send signals to the earth. The ground control part is responsible for monitoring satellites and transmitting data. The user equipment part can receive satellite signals and calculate the position, speed and time. Among them, the ground control part includes the main control station, monitoring station and ground control station. The user equipment part is usually a GPS signal receiver. When in use, rescuers can quickly obtain their precise latitude and longitude coordinates through the GPS signal receiver (GPS handheld device) they carry, and combine this information with map data to determine their relative position and distance from the disaster area. This not only helps rescuers plan the fastest route, but also avoids getting lost in complex terrain and saves precious rescue time. At the same time, the navigation function in the GPS navigation device can provide real-time navigation guidance for rescue vehicles. In the case of road congestion or damage, the navigation system can plan feasible alternative routes for rescue vehicles based on real-time traffic information and satellite images, avoid dangerous areas, and ensure that the rescue team can reach the rescue site safely and quickly. In addition, GPS technology can also be used to assess the scope and extent of the disaster-stricken area. That is, using satellite images and GPS positioning data, relevant departments can quickly draw a map of the disaster-stricken area, determine the worst-hit areas and locations that need priority rescue. This helps to reasonably allocate rescue resources and ensure the focus and direction of rescue work. In addition, the GPS positioning in the trapped person’s mobile phone can be used to achieve high-precision positioning of the trapped person’s position, helping rescuers to quickly determine the position of the trapped person for accurate rescue. Among them, GPS navigation devices mainly receive signals from satellites for positioning, so their core functions do not rely on network connections. Since GPS devices determine their location by receiving satellite signals, the quality and quantity of satellite signals directly affect the accuracy and stability of positioning. In addition, GPS navigation devices can also transmit data through the network. For example, some GPS devices have built-in GPRS modules, which can transmit positioning data to remote devices through public networks. ‌‌ In addition, as attached Figure 1 and Figure 2As shown, the front-end video acquisition device is also carried and used by rescue personnel. The front-end video acquisition device is connected to the backpack base station through signals. The front-end video acquisition camera device collects and acquires the actual image signal in front and transmits it to the video acquisition device in the rear through a wireless network. It is the core part of the entire system, generally including helmet cameras, pan-tilt cameras, control balls and single-soldier terminals, etc., mainly used to collect on-site images and videos. Depending on the environment being photographed and the location of the camera, the specific configuration of the camera device is also different. At the same time, in order to meet the requirements of the rescue environment, it can be selected according to the application requirements. The video acquisition system can be seamlessly connected with the wireless ad hoc network equipment to ensure that the remote front video signal is transmitted to the communication vehicle and the back-end monitoring command center through the ad hoc network. Among them, the backpack base station is mainly connected to the helmet camera and the pan-tilt camera by wireless means, and the communication is realized by using the ad hoc network technology. In actual applications, the backpack base station and the helmet camera and the pan-tilt camera can transmit data through wireless multi-hop relays or drone airborne nodes to ensure that high-definition video information can be stably transmitted in complex environments. This wireless connection method makes the equipment more flexible and adapts to the emergency communication needs in various complex environments.

[0021] The surveillance ball is a mobile monitoring device that integrates high-definition video and Mesh self-organizing network technology. It has a built-in high-performance wireless broadband self-organizing network module and supports multiple network access methods (including 4G / WiFi / RJ45), ensuring that a stable and reliable monitoring network can be built in various complex environments. It can transmit on-site video images in real time, provide the command center with real-time monitoring and understanding of the front line of the disaster, and help command decision-making. The connection between the backpack base station and the surveillance ball is mainly achieved through wireless self-organizing network technology. For example, the surveillance ball collects actual image signals and transmits them to the video acquisition equipment in the rear through a wireless network. They can provide functions such as high-definition video return and video distribution to ensure accurate and smooth information and achieve barrier-free communication. This connection method does not require cable laying, and the construction is simple and quick to deploy. In addition, the backpack base station is also connected to the single-soldier terminal through wireless self-organizing network technology to achieve real-time transmission of voice, data and positioning information. The single-soldier terminal provides communication, positioning and distress functions for individual rescuers, so that each rescuer can keep in touch with the command center in time, improving rescue efficiency and safety. In addition, if attached Figure 1 and Figure 2As shown in the figure, rescuers can also carry life detectors and vital signs monitors according to the rescue situation. Both life detectors and vital signs monitors are connected to the network through a backpack base station. ‌ Life detectors are high-tech equipment used to detect signs of life. They are mainly used in disaster rescue scenarios, such as earthquakes, fires and other emergency situations, to help rescuers quickly find trapped people. ‌ When a disaster occurs, life detectors can quickly and accurately find survivors by detecting vital signs, thereby greatly improving rescue efficiency. The working principle of life detectors is based on a variety of technologies, the most common types of which include radar life detectors, audio life detectors and infrared life detectors. Radar life detectors use radar technology to detect life by analyzing the time domain Doppler effect generated by human movement on radar echoes; audio life detectors use the principles of sound waves and vibration waves, and are suitable for rescue work in limited spaces and places that are difficult to access by conventional methods; infrared life detectors locate survivors by detecting infrared radiation emitted by the human body. The vital signs monitor can be made into a bracelet and worn on the rescuer's wrist. The vital signs monitoring bracelet can monitor and record the rescuer's heart rate, blood pressure, blood oxygen saturation, body temperature, sleep quality and other key vital signs data in real time through the built-in high-precision sensor. These data reflect the rescuer's current health status, which is conducive to ensuring the rescuer's life safety and preventing the rescuer from overdrawing their lives.

[0022] In summary, when a major natural disaster occurs, the present invention allows frontline personnel to connect communication vehicles, drones, backpack base stations, communication equipment, front-end video acquisition equipment, and back-end monitoring and command centers to the ad hoc network, quickly build a wireless ad hoc network on site, and then combine it with public networks, private networks and other communication methods. In view of the different communication distances between nodes and the difficulty in laying wired lines, communication can be completed through ad hoc network equipment, achieving network self-repair and recovery, ensuring the smooth transmission of information, and facilitating rescue personnel to understand the disaster more quickly, formulate rescue plans and take action. In addition, in case of cross-regional communication needs, satellite communications can also be used to solve the problem of ultra-long-distance communications and ensure rescue communications. The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
