Natural disasters such as earthquakes, snow disasters, floods, and hurricanes are difficult to defend against. Once they occur, they will cause varying degrees of loss. For example, after an earthquake, fixed-line and mobile communications in the disaster-stricken area are usually greatly damaged, and communications between the outside world and the disaster-stricken area are interrupted, and the situation in some of the hardest-hit areas cannot be obtained. This directly affects the leadership of the Party Central Committee and the State Council to deploy rescue and relief work. Due to the complete interruption of communications and traffic jams in special areas, it is impossible to get in touch with the outside world and become “isolated cities.” The interruption of information directly affects the rescue and disaster relief work. As the general headquarters of rescue and disaster relief, it is necessary to fully grasp all aspects of the disaster area and lay the foundation for formulating scientific and reasonable disaster relief plans. At the same time, the orders issued should be communicated to all departments as soon as possible. On the one hand, a complete communication system is required to ensure uploading and delivery. On the other hand, there must be a fully functional communication command center to integrate the communication system and maximize the communication support capability-this requires a communication command with strong mobility and complete functions. vehicle.
The country is increasing civil air defense engineering construction planning, and the use of communication command vehicles can greatly enhance communication support capabilities, increase the speed of civil air defense command response, and provide strong guarantees for air defense, disaster prevention, disaster relief, and emergency rescue. The multi-functional communication command vehicle can be responsible for on-site information collection, processing, and transmission tasks according to needs, and can be used as a communication hub for handling emergencies and disaster relief. Can use shortwave, ultrashortwave, microwave, satellite communication and other means to provide command center leaders with on-site images, voice, data and other information to ensure that leaders have real-time, intuitive and accurate first-hand information on the scene of the incident, and can also provide on-site command The ultrashort wave communication provides relaying, thereby improving the rapid response and processing ability of responding to emergencies. The communication command vehicle can be used not only in emergency rescue, but also as a communication command vehicle for various large-scale events such as the Olympic Games and the Asian Games. It serves as a hub to temporarily set up a communication network and dispatch various wireless communication equipment.
The State Council has separately dealt with “national safety production”, “handling railway traffic accidents”, “civil aircraft flight accidents”, “maritime search and rescue”, “urban subway accidents and disasters”, “power grid outages”, “nuclear emergency”, and “sudden accidents”. 9 issues such as “Environmental Incidents” and “Communication Guarantee Emergency” have issued special emergency plans for public emergencies such as accidents and disasters. In response to this emergency plan, all provinces and cities are preparing mobile emergency communication command systems.
In order to meet the needs of emergency operations in wartime and peacetime, mobile communication systems should include the following systems: single-sideband shortwave communication systems, ultra-shortwave communication systems; wired communication systems; network systems; satellite communication systems; warning signal distribution systems.
Single-sideband shortwave communication systems: optical fibers, mobile communications, etc., are communication methods that rely on line connections and base stations to achieve radio signal coverage. Once the optical fiber is broken, the base station power-off equipment loses its function, and communication and command basically fail. Satellite communication equipment is expensive and has a low penetration rate. The only reliable means of communication is a single-sideband radio shortwave radio station. The radio station is set up, removed, easy to use and fast, and the power supply problem is easy to solve. It is mainly used for communication between provinces, states, and counties.
Ultrashort wave communication network: mainly used for command communication to cities, districts (counties), civil air defense teams and key units.
Wired communication system: It can connect the wireless signal to the wired communication network to realize the communication from wireless to wired.
Wireless network system: mainly used for the transmission of AV signals and data signals. It can transmit the audio and video signals of the incident scene to the command center in real time through the network for leaders to make decisions and commands, and play an important role in the mobile communication system.
Satellite communication system: It can be used for long-distance, military-to-land, coordination and emergency communication support.
Alarm signal issuing system: mainly used for mobile control and issuing various alarm control signals.
