Abstract
The invention relates to a system for realizing the collective broadcast of beidou satellite communication short-messages, which comprises a beidou master station and beidou slave stations, wherein short message communication is performed among the beidou master station and the beidou slave stations by beidou short-message communication modules, the beidou short-message communication module in each beidou slave station is at least provided with a beidou IC (integrated circuit) card with a same user ID number. And the beidou short-message communication module in each beidou slave station also can be provided with beidou IC cards with different user ID numbers. If the beidou master station sends short messages to the beidou slave stations by using a same user ID number, all the beidou slave stations can receive the short messages, thereby realizing the function of collective broadcast. If the beidou slave stations are also provided with the IC cards with different user ID numbers, the beidou slave stations also can send short messages to the master station, thereby realizing two-way communication. The system disclosed by the invention has the characteristics that the cost of the master station is low, the number of the slave stations is unlimited, and the system is applied conveniently, and the like.
Description
One, technical field
The present invention relates to a kind of Beidou satellite navigation communication system, particularly a kind of system that realizes the logical multicast function of big-dipper satellite communication short message.
Two, background technology
Beidou satellite navigation system is China's global positioning satellite and communication system (BDS) of development voluntarily, is the satellite navigation system of the 3rd maturation after U.S. global positioning system (GPS) and Russia GLONASS.The dipper system user terminal has the bi-directional communication function, and communication mode has the logical communication mode of broadcasting of point-to-point communication mode and one-to-many, only has at present the command type terminal could realize the logical communication mode of broadcasting of one-to-many.The command type terminal can realize that logical to broadcast, supervise receipts etc. multi-functional, but price is very expensive, and the membership setting program of master station and follow station is comparatively complicated, the slave station limited amount.How, under low-cost condition, realize that the logical multicast function of big-dipper satellite communication short message is to need a problem that solves.Can strengthen like this range of application and the competitiveness of Beidou satellite navigation communication system at air defence warning granting, weather warning, data acquisition, Remote, these application only need to solve the logical problem of broadcasting, and without the prison of being concerned about main website, receive function.
Three, summary of the invention
(1) goal of the invention
For the problem that will solve in above-mentioned prior art, the purpose of this invention is to provide a kind of system that realizes the logical multicast function of big-dipper satellite communication short message, have the characteristics such as the main website cost is low, slave station quantity unrestricted, application is convenient.
(2) technical scheme
The present invention is achieved in that a kind of system that realizes the logical multicast function of big-dipper satellite communication short message, comprise Big Dipper main website and Big Dipper slave station, in Big Dipper main website, comprise Big Dipper short message communication module, in Big Dipper slave station, comprise Big Dipper short message communication module, between Big Dipper main website and Big Dipper slave station, by Big Dipper short message communication module, carry out short message communication, the Big Dipper short message communication module in described each Big Dipper slave station is equipped with a Big Dipper IC-card with same user ID number at least.
Big Dipper short message communication module in above-mentioned each Big Dipper slave station also can be installed the Big Dipper IC-card with different user id number.
Above-mentioned Big Dipper short message communication module is comprised of baseband chip, IC-card, memory, communication interface, radio frequency chip, amplifier, antenna etc., and Big Dipper IC-card is connected with baseband chip.
Operation principle of the present invention is: Big Dipper main website sends short message to the same user ID number of Big Dipper slave station, and each Big Dipper slave station can be received, has therefore realized logical multicast function.If Big Dipper slave station also is equipped with the IC-card of different user id number, these Big Dipper slave stations can also send short message to main website, realize two-way communication.
(3) technique effect
The present invention has the characteristics such as the main website cost is low, slave station quantity unrestricted, application is convenient.
