Problems solved by technology

[0003] At present, the short message communication service of the Beidou satellite system is mainly for one Beidou user terminal to send short messages to another Beidou user terminal, and it is impossible for one Beidou user terminal to send broadcast short messages to a large number of Beidou user terminals
This greatly limits the information release function of the Beidou satellite system in the emergency rescue and command of civil earthquakes and other disasters in my country

Embodiment Construction

[0020] like figure 1 As shown, the civil information publishing system based on the Beidou satellite system provided by the present invention includes information publishing software (1), information publishing terminal (2), Beidou satellite system (3), and information receiving terminal (4).

[0021] Information release software (1): Receive and process an information release request from a user and a designated civilian SIM card number. The published information is encoded into the Beidou short message format and sent to the information publishing terminal (2) through the RS232 serial port.

[0022] Information release terminal (2): send the short message to the Beidou satellite system (3) through the uplink communication link.

[0023] Beidou satellite system (3): send the short message to an information receiving terminal (4) on the ground through a downlink communication link.

[0024] Information receiving terminal (4): all information receiving terminals (4) set with ...

Abstract

The invention relates to a civil information release system based on a Beidou satellite system. By using the system of the invention, one Beidou user terminal sends a broadcast-class short message to a lot of Beidou user terminals so that the Beidou satellite system achieves an information release function during our country civil emergency rescue of an earthquake and other disasters and commanding. The system of the invention comprises information release software (1), an information release terminal (2), the Beidou satellite system (3) and information receiving terminals (4). By using the system of the invention, broadcast, multicast and unicast of the information release is realized to short message content expansion and definition. Each information receiving terminal (4) is provided with an expanded terminal group number and a terminal device number.

Description

technical field [0001] The invention relates to a satellite information publishing system, in particular to a system for publishing civil information by using the Beidou satellite system. Background technique [0002] Beidou satellite navigation system is a global satellite navigation system independently developed and operated by my country. The first phase of Beidou began in 2000, with the successful launch of 3 GEO satellites and the completion of the Beidou satellite navigation test system. The system can provide basic positioning, timing and short message communication services. The second phase of Beidou will cover the Asia-Pacific region around 2012 and eventually the world by 2020. The Beidou satellite system can provide Beidou user terminals with positioning services for navigation and positioning, timing services with standard time sources, and short message communication services for broadcast and two-way communication. Each Beidou user terminal must insert the...
