Application of CONQUEST Tiantong Satellite Mobile Phone in Forest Fire Fighting
1 Hazards of forest fires
At 17:00 on March 30, 2019, a forest fire broke out in Lier Village, Yalongjiang Town, Muli County, Liangshan Prefecture, Sichuan Province. Thirty firefighters have been killed. Forest fires have the characteristics of sudden, strong, and difficult to deal with. Once a forest fire occurs, a large number of cover plants will be burned, causing harm to the local ecological environment and people's lives and property. Before and after the Qingming Festival, it was the peak period of fire for folk customs. The fire for ancestral burning of paper and spring plowing for production was superimposed. It was frequent to enter the mountains and travel and leisure activities. It was more difficult to control the source of fire. The country has entered a critical period of fire prevention and extinguishment in spring forests and grasslands.
2 Difficulties of Forest Fire Fighting
China's forest coverage is high, and the ground vegetation and combustible materials in the forest are high. Rotating occurs and a large amount of combustible gas is generated. When affected by wind and wind, it will cause forest fires to explode. The ignition points of forest fires are mostly in places with steep terrain, ridges, saddles, and single-valley valleys, where complex terrain and closed communications are not convenient.
Forest fire prevention teams get the news at the first time, which is the focus of fire fighting. The mobile network in mountainous areas is difficult to cover and communication is difficult. It is difficult for fire extinguishers to reach the scene of the fire in time, and it is difficult to communicate and direct rescue in the disaster area. 3 satellite communication and CONQUEST Tiantong satellite mobile phone
In August 2016, the first star of China ’s satellite mobile communication system, Tiantong No. 01, was successfully launched. In May 2018, China Telecom first issued a number for the commercial market, filling a gap in China's autonomous mobile communication system.
Tiantong-1 satellite mobile communication system is composed of space segment, ground segment and user terminal.
The space segment is planned to consist of multiple geosynchronous orbit mobile communication satellites.
The terrestrial business is operated by China Telecom Corporation and will form a mobile communication network with the ground mobile communication system.
To provide users in China with all-weather, all-day, stable and reliable mobile communication services, and support voice, short message and data services. 4CONQUEST Tiantong Satellite Phone Features
CONQUEST Tiantong satellite mobile phone is not subject to any complicated geographical conditions between the two communication points and any natural disasters and human events. The CONQUEST Tiantong satellite mobile phone is based on the Tiantong satellite communication system as a support to achieve high communication quality and high system reliability. The cost of satellite phone communication has nothing to do with the communication distance. The communication distance spans the north and south of our country and runs from east to west. Application of 5CONQUEST Tiantong Satellite Mobile Phone in Forest Fire Fighting
Establishing a complete and stable communication system for the prevention, suppression and protection of forest fire prevention will not only help stop the fire in a timely manner, but also help reduce casualties. Therefore, the construction of forest fire communication is incorporated into the local fire construction plan to achieve seamless coverage of communication capabilities. Facts have proved that when faced with force majeure natural disasters such as forest disaster relief, the CONQUEST satellite mobile phone is an incomparable communication device. At the same time, as an important member of national security protection, only the self-developed Tiantong No. 1 communication network can ensure the security of communication information. Implementing satellite phones as a command network system in forest firefighting, introducing new equipment for firefighting, and comprehensively improving the equipment standards of fire brigades. In this way, the timely rescue of forest fire protection is improved, the secondary damage of resources, life and property to the fire is minimized, and the safety of rescuers is guaranteed.
