In western China, about 71.4% of the country's land, the area suitable for cultivated land is 100 million mu, accounting for 57% of the country's reserve cultivated land resources. The western region has vast mineral resources, land resources and underwater resources, and has very large development resources. As we hear and see, there are electricity transmission from west to east, gas transmission from west to east and gas transmission from Sichuan to east. However, as the terrain is mostly distributed in mountainous areas and the climate type is changeable, in the face of steep terrain and high intensity rainstorm, large-scale geological disasters are often formed, which is the reason for the frequent geological disasters in the western region at present, and also brings many hidden dangers to the local residents.

In the face of such complex and changeable terrain and weather, safety monitoring and emergency prevention are the primary task at present. Especially, Hanzhong in Shaanxi Province, Linxia and Dingxi in Gansu Province, and Guyuan in Ningxia Province, which are prone to heavy rainfall, are prone to geological disasters, which are likely to cause many casualties. On September 26, Huang Ming, deputy commander of the State Defense General and Minister of Emergency Management, hosted a video conference to connect Beijing, Hebei, Shanxi, Shandong, Henan, Hubei, Chongqing, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu and other provinces (municipalities), emergency management departments (burets), fire rescue corps and forest fire brigade.

According to the meeting, it is necessary to adhere to the rolling consultation, research and judgment, strengthen short-impending forecast and early warning, effectively cope with short-term heavy rainfall and other extreme weather, short-impending forecast and early warning, emergency action and local emergency plans closely. To comprehensively investigate risks and hidden dangers, the implementation of flood control measures, the major risks and hidden dangers out of the investigation, especially the external construction team, shed sites into the risk investigation, put an end to blind areas. We should attach great importance to social mobilization and social organizations, mobilize grassroots organizations and social forces in a timely manner, and make effective use of mobile phone text messages, television, radio and newspapers for extensive social mobilization to ensure that early warning information reaches every household. Important roads in disaster-hit areas should be controlled in time to prevent secondary disasters. Prevention and emergency management departments at all levels should, in the spirit of being highly responsible for the safety of people's lives, have the courage to assume their responsibilities, be good advisers and assistants, make preparations for rescue and rescue, start response in a timely manner, strengthen the mobilization of mass organizations, and implement all measures to prevent and respond to autumn rains and autumn floods and work safety.

For major disasters and accidents, Shenzhen Suntor was invited by a company to customize a set of communication system suitable for western landforms and emergency situations for a city emergency bureau in the west. In view of landform and frequently occurring geological disasters in western China, our company has developed a mesh communication system based on Suntor to ensure that the Bureau can have a complete and available communication system that can send the actual situation of the site back to the command center in real time and issue emergency instructions at any time after the occurrence of emergency events.

Front-end rescue personnel are equipped with a single mesh ad-hoc networking device to send the actual situation of the scene back to the emergency command vehicle or UAV through the mesh ad-hoc network link. The link can carry 1080P~4K high-definition video, high-definition images, high-definition bidirectional voice, and other environmental data information, personnel physical signs information and other sensor information collected on the scene.

After receiving the information sent back by the front-end single mesh ad-hoc network equipment, the field command vehicle can send the field information back to the command center through the private network, 4G/5G, satellite and other communication means of the command vehicle, so that the superior professional command personnel can quickly understand the actual situation on the site, and at the same time collect multiple single return information to make a comprehensive emergency plan. Rapid emergency action instructions, greatly improve the front impact speed, field deployment, rapid emergency capacity, so that the rescue action quickly implemented to the point, effectively curb people's property losses, effectively protect people's lives and property safety.

Front-end loading equipment, Suntor96 series single hand-held transmission equipment, micro airborne Mesh equipment, high-power emergency vehicle platform three mesh network equipment linkage, constitute a complete on-site emergency command link; The Suntor dispatching and command platform is installed and laid in the back-end command center. Through the emergency command and dispatch system, the commanding personnel can quickly grasp the trends on the scene, make quick decisions based on the information returned on the scene, make comprehensive analysis, and complete the emergency command and dispatch on the scene. Thus, a complete emergency communication system and command and dispatch system are formed, and perfect emergency plans and measures are established.

Equipment characteristics

• High adaptability, for a variety of emergencies complex environment can support non-line-of-sight environment work.

• Can cover a wide range, whether plain, hill or mountain environment, can achieve a large area of signal coverage.

• High anti-interference ability, the equipment can automatically adjust the modulation mode and transmission power according to the channel condition. Eliminate interference by other signals. The characteristic carrier can also be turned off manually to prevent mutual interference.

• High strength fading resistance, OFDM technology, has excellent ability to resist multi-path fading. When a set of data is propagated through multiple subcarriers, the signal time on each subcarrier increases exponentially compared with that on a single-carrier system with the same rate, making OFDM more resistant to pulse noise and fast fading of the channel.

• Networking is flexible, plug and play, Suntor proprietary MESH communication protocol. Ethernet interface, transparent transmission, after connecting to the device, power on to realize automatic networking communication.

• Multiple extension services can be switched between different modes based on site networking and network scale, structure, and rate.

• Real-time online, wireless transmission, to achieve efficient interaction and accurate and efficient command and dispatch capabilities;

• Emergency alarm, quickly lock the alarm personnel azimuth, accurate immediate response processing;

• Multi-channel data transmission, to ensure the real-time dispatch of command personnel, to ensure the smooth flow of signals;

• Multi-level scheduling. In the face of emergencies, multi-level scheduling commands can be selected to achieve rapid and accurate command scheduling for processing.

• High data bandwidth fast movement. Fast movement does not affect high data bandwidth services. Voice, data, and video services are not affected by rapid changes in system topology and high-speed terminal movement.

• Reliable performance, the design is fully tailored to the electromagnetic compatibility, shock resistance, temperature, humidity and other suitable field working environment of the equipment in the actual combat environment.

• Simple operation, simple operation, no special training, you can get started, support Ethernet transparent transmission, no additional configuration, any network can realize mutual transmission.

• Personalized customization, to meet customer customization of a variety of personalized solutions.

• Fault self-check, automatic notification of dispatch center and equipment maintenance personnel when system failure occurs;

• Low cost, its own system is equivalent to the standard cluster mode, for all industries digital management, low cost;

• Easy maintenance: compatible with different frequency bands, various voice communication and data access interconnection, more convenient maintenance.
