TD-LTE emergency communication terminal based on Beidou GPS dual-mode positioning, and monitoring command system

Abstract

The invention relates to a TD-LTE emergency communication terminal based on Beidou GPS dual-mode positioning, and a monitoring command system, and belongs to the technical field of communication. The system comprises communication terminals based on a Linux system, and the network communication between the communication terminals and between the communication terminals and a monitoring command center. Each communication terminal comprises a power module, a Beidou GPS dual-mode positioning module, a voice module, a communication transmission module, and a display control module. The Beidou GPS dual-mode positioning module is used for achieving a function of satellite positioning, and the voice module is used for achieving voice input and output. The display control module is used for the processing and displaying of data information, and the operating of the whole communication terminal. The system is based on the technology of Beidou GPS dual positioning and TD-LTE, is accurate, reliable and quick in positioning, is high in communication rate, is small in time delay, is good in stability, is convenient to operate, is suitable for the rescue in natural hazards, the guarantee for public security, the anti-terrorist stability safeguard and emergency rescue, and provides quick and reliable communication, navigation, command and dispatching services.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a TD-LTE emergency communication terminal and a monitoring command system based on Beidou GPS dual-mode positioning. Background technique [0002] The Beidou satellite positioning system is a satellite positioning system independently developed by my country. Satellite navigation system is an important space information infrastructure, and our country attaches great importance to the construction of satellite navigation system. Has been working hard to build and develop a satellite positioning system with independent intellectual property rights. At present, the system has been successfully applied in many fields such as surveying and mapping, telecommunications, water conservancy, fishery, transportation, forest fire prevention, disaster reduction and relief, and public safety. However, there is still a gap between the Beidou navigation system and the GPS system. The perf...
