MESH equipment plays an important role in emergency response
As the year draws to a close, sporadic outbreaks have occurred in many parts of my country, and the raging epidemic has once again tested the emergency response capabilities of local governments. Urban emergency control is once again before us. With the rapid development of my country's overall economic construction, the urban economic system is also growing, and various contradictions and dangerous factors in the city are also increasing. In the face of such situations, in order to ensure the harmonious, civilized and safe development of the city, it is imperative to establish a complete urban emergency control communication solution. Modern urban emergency control communication systems usually use Mesh self-organizing network equipment as the core equipment of the entire system. The entire communication system closely combines the advantages of Mesh self-organizing network with intelligent robots, drones and other systems. It consists of a transmitter and a receiver, which solves the problems of high cost and mutual interference of traditional video control systems. It can fully realize the two-way high-definition digital wireless image transmission function within a range of 3-50 kilometers; and can communicate with other wireless broadband self-organizing network equipment in the air and on the ground through relays. A wireless data transmission network with large coverage, high-speed movement and multi-hop transmission can be established in a short time. Its advantages such as non-center self-organization and low latency are very suitable for wireless image transmission applications in complex environments such as urban emergency communications.
Urban emergency control is the continuous on-site reconnaissance and real-time monitoring of various emergencies in the city, providing a basis for the command and decision-making of commanders at all levels. It is the focus and difficulty of this type of rescue mission. It is usually used to maintain urban safety, firefighting, rescue and other emergency places. To conduct real-time monitoring of such places, the required equipment must meet the following characteristics: strong mobility, easy to penetrate into the event center and the event site, small equipment size, high weight, suitable for single-soldier squad communication needs, easy to operate, and suitable for rapid deployment. The converged communication of wireless ad hoc network + 5G multi-card aggregation technology plays a vital role in urban emergency control. The characteristics of MESH are as follows:
1. Strong transmission capability: The wireless transmission between nodes adopts MESH modulation technology, which can achieve a single-point transmission distance of up to 50-70 kilometers in a line-of-sight environment or a single-point transmission distance of 2-5 kilometers in a non-line-of-sight environment.
2. Intuitive and clear management: Each MESH wireless self-organizing network device has a built-in Chinese network management software with a web interface, which can realize the management and monitoring functions of the wireless self-organizing network devices in the entire network.
3. Strong anti-destruction performance: This system is a centerless self-organizing network structure that can support up to 16 nodes in the same frequency network. The network topology can change in real time and automatically form a network according to the actual situation of the emergency rescue mission and the actual location between the nodes. In this network, any device can realize the self-organizing network function. If any device in the group is disconnected, the corresponding device will continue to communicate within the effective antenna coverage to ensure that the network is not disconnected.
4. Self-contained positioning function: After positioning through Beidou (or GPS), the location information can be transmitted to the command vehicle or the command information terminal of the commander who leaves the vehicle through the wireless ad hoc network system. The commander in the vehicle or the commander who leaves the vehicle can locate the position of each on-site team member and drone in real time.
Through the city emergency control communication system, relevant departments can achieve unified deployment and rapid response to major urban safety incidents, fire, traffic accidents, etc., and control the hazards to a minimum. Thereby ensuring the safety of urban citizens and property. Our company has a complete urban emergency control communication system solution and powerful Mesh wireless ad hoc network equipment, and the collaborative work of the wireless emergency command system is mainly used in the rescue emergency communication command of major urban accidents and geological disasters, as well as emergency departments, fire protection, water conservancy, forest defense, border defense, civil defense emergency, border defense, earthquake, urban management, electricity, road administration and other industries.
