Abstract
The utility model relates to a system capable of performing a Beidou satellite communication short message broadcasting function. The system comprises a Beidou master station and at least one Beidou slave station, short message communication is carried out between the Beidou master station and any one Beidou slave station through a Beidou short message communication module, and at least one Beidou IC card having the same user ID number is mounted on the Beidou short message communication module in each Beidou slave station Beidou IC cards having different user ID numbers can also be mounted. When a short message is sent to the same user ID number of the Beidou slave stations by the Beidou master station, all the Beidou slave stations can receive the short message, and therefore the broadcasting function is realized. If IC cards having different user ID numbers are installed in the Beidou slave stations, the Beidou slave stations can send short messages to the master station, and bidirectional communication is achieved. The system capable of performing a Beidou satellite communication short message broadcasting function is characterized by low cost, zero restriction of slave station quantity, convenience of application 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 3rd ripe satellite navigation system after U.S. global positioning system (GPS) and Russia GLONASS.Dipper system user terminal has 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 command type terminal could realize the logical communication mode of broadcasting of one-to-many.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, slave station limited amount.How under low cost condition, realize the logical multicast function of big-dipper satellite communication short message and be and need a problem solving.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 receive function without the prison of being concerned about main website.
Three, summary of the invention
(1) goal of the invention
For the problem that will solve in above-mentioned prior art, the object of this invention is to provide a kind of system that realizes the logical multicast function of big-dipper satellite communication short message, there is the features such as 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, carry out short message communication by Big Dipper short message communication module, the Big Dipper short message communication module in each Big Dipper slave station is at least provided with a Big Dipper IC-card with same user ID number.
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 made up 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 is also provided 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 features such as main website cost is low, slave station quantity unrestricted, application is convenient.

Big Dipper short message communication module in above-mentioned each Big Dipper slave station also can be installed the Big Dipper IC-card 34 with different user id number.
With reference to Fig. 2, the principle schematic of Big Dipper short message communication module of the present invention: Big Dipper short message communication module is made up of baseband chip 3, IC-card 33, IC-card 34, memory 31, communication interface 32, radio frequency chip 4, amplifier 5, antenna 6 etc., and Big Dipper IC-card is connected with baseband chip.
Adopt after such scheme, operation principle of the present invention is:
Big Dipper main website 1 sends short message to the same user ID number of Big Dipper slave station 2, and each Big Dipper slave station 2 can be received, has therefore realized logical multicast function.If Big Dipper slave station is also provided with the IC-card 34 of different user id number, Big Dipper slave station 2 can also send short message to main website 1, realizes two-way communication.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
