Problems solved by technology

[0003] With the development of my country's Beidou business and the extensive use of Beidou short message functions, there are still the following limitations in the application of Beidou short messages in remote data transmission and control: using short message communication, there is a communication capacity limit for one communication, That is, the length of each communication content is limited, and the communication capacity is small. In general, the civilian communication capacity is only about 100 bytes; the communication frequency is limited, that is, there is a certain time interval between every two communications. And this time interval is relatively large, under normal circumstances, the frequency of civil communication is around 60
That is, the Beidou short message system has a small communication capacity and a low communication frequency. These characteristics make the amount of data transmitted in real time generally small. When a large amount of data needs to be transmitted in real time, the transmission data rate is far from enough

Embodiment 1

[0037] Embodiment 1 of the present invention provides a Beidou communication device, see figure 1 As shown, it includes Beidou transceiver host 1 and server 2.

[0038] The Beidou transceiver host 1 is used for sending and receiving Beidou short messages in parallel.

[0039] The server 2 is configured to store the Beidou short message sent or received by the Beidou transceiver host, and publish the received Beidou short message.

[0040] Preferably, see figure 2 As shown, in Embodiment 1 of the present invention, the Beidou transceiver host 1 includes a Beidou transceiver antenna 11 , a Beidou transceiver box 12 and a host 13 .

[0041] The Beidou transceiver antenna 11 is connected to the Beidou transceiver box 12; the Beidou transceiver antenna 11 is used to send and receive the Beidou short message.

[0042] The Beidou transceiver box 12 is used for parallel processing of the Beidou short messages received and sent by the Beidou transceiver antenna, and supports multip...

Embodiment 2

[0063] Embodiment 2 of the present invention provides a Beidou communication method, see image 3 shown, including steps:

[0064] Step S110: Sending and receiving Beidou short messages in parallel.

[0065] Parallel sending means parallel processing of Beidou short messages received and sent by the Beidou transceiver antenna, and supports multiple Beidou short message communication addresses to share signal channels including radio frequency and baseband signals.

[0066] Step S111: storing the Beidou short message sent or received by the Beidou transceiver host, and publishing the received Beidou short message.

[0067] Because the Beidou short message does not have the function of communication receipt, after the terminal sends the Beidou short message in the prior art, it is impossible to know whether the other party has received it. However, the technical solution of the present invention, in addition to the Beidou communication mechanism, also sets the short message and...

Abstract

The invention relates to the technical field of satellite communication, in particular to a Beidou communication device and method. The Beidou communication device comprises a Beidou transmitting-receiving main machine and a server, wherein the Beidou transmitting-receiving main machine is used for parallely transmitting and parallely receiving Beidou short messages, and the server is used for storing the Beidou short messages transmitted or received by the Beidou transmitting-receiving main machine and issuing the received Beidou short messages. The Beidou communication method comprises the steps of parallely transmitting and parallely receiving the Beidou short messages, storing the Beidou short messages transmitted or received by the Beidou transmitting-receiving main machine, and issuing the received Beidou short messages. According to the Beidou communication device and method, one-time transmitting message capacity is improved, and the parallel mode can achieve large volume data information issuing and warning information can be transmitted to a plurality of different areas in a grouping mode on the premise that the frequency of communication is kept unchanged.

Description

technical field [0001] The present invention relates to the technical field of satellite communication, in particular to a Beidou communication device and method. Background technique [0002] The Beidou navigation test system is the first generation of satellite navigation and positioning system independently developed and built by my country. It is the third actually operating navigation and positioning system in the world after the US "GPS" system and the Russian "GLONASS" system. In addition to the characteristics of large coverage, no communication blind spots, safety and reliability, Beidou satellite communication also has a special short message communication function, which enables users to realize short message communication through satellites, and is not affected by terrain conditions and environmental climate Impact. This function can be used to solve short message communication in sparsely populated rural areas, pastoral areas, remote mountainous areas, sea area...
