Description

Technical Field

[0001] This application relates to the technical field of satellite communications, and in particular to a converged network emergency satellite communication system. Background Technology

[0002] The main function of a modern satellite emergency communication and command system is to promptly, rapidly, accurately, and comprehensively understand the on-site situation of various emergencies, conduct real-time command, and minimize the losses caused by various emergencies. For a typical satellite emergency communication and command system, the currently known model consists of two parts: a fixed emergency command center and a mobile emergency command center, which establish a broadband two-way communication link through satellite relay. The fixed emergency command center's function is to conduct command and dispatch based on the on-site information provided by the mobile emergency command center; its communication site can be constructed in advance before the emergency occurs. The mobile emergency command center's function is to collect video, audio, and data information from the emergency site and transmit it back to the fixed emergency command center in real time, and receive command and dispatch orders from the fixed emergency command center, achieving real-time two-way communication; its communication site must be temporarily constructed according to the time and location of the emergency.

[0003] Currently, the construction of mobile emergency command center sites generally adopts two methods: 1. Using emergency satellite communication vehicles modified by professional manufacturers and equipped with satellite communication terminal systems; 2. Transporting various emergency satellite communication equipment to the emergency site by ordinary vehicles, where engineers complete the connection and debugging of the equipment on-site. The former requires high vehicle performance and modification technology, resulting in huge investment, while the latter requires highly specialized operators and involves complex equipment connection and debugging, demonstrating its inadequacy in responding to emergencies.
