Problems solved by technology

However, there are still few solutions involving message coding, compression and transmission for meteorological disasters
In addition, the frequency limitation of Beidou civil message communication has not been well resolved. When a major meteorological disaster occurs, if dozens or hundreds of handheld terminals report to the command center at the same time, it will cause a large time delay and disaster situation. Data timeliness will be greatly reduced

Abstract

The invention discloses a meteorological disaster situation real-time reporting system based on Beidou short message communication. The system comprises a disaster situation reporting handheld terminal and a command center. A master control module in the disaster situation reporting handheld terminal is physically connected with a Beidou positioning and message transmission integrated module, a power module, a storage module, a touch screen and display module and a data interface module. A Beidou application server in the command center is connected with a Beidou transmitting and receiving array, a disaster situation geographic information system, a data backup server and a Web server, and the command center is connected with the disaster situation reporting handheld terminal through a Beidou satellite system. The meteorological disaster situation real-time reporting system can rapidly report disaster situation information and meet the requirement for meteorological disaster emergency command and rescue in real time on the condition of mobile signal interruption when major meteorological disasters occur, and the emergency command and disaster rescue speed can be increased to the maximum degree.

Description

technical field [0001] The invention belongs to the field of emergency management of meteorological disasters, and in particular relates to a real-time reporting system of meteorological disasters based on Beidou short message communication. Background technique [0002] my country is a country that suffers from many meteorological and natural disasters, and major meteorological disasters occur every year, causing a large amount of economic losses. When some major meteorological disasters occur, mobile communication, electric power and other systems will be interrupted, and the disaster emergency command department cannot obtain the real-time situation of the disaster in the disaster-stricken area in time, which brings greater difficulty to emergency rescue. The Beidou satellite system is a global satellite navigation and positioning system independently developed by my country. Compared with the GPS of the United States, the GLONASS of Russia, and the Galileo system of the ...
