[0038] In this embodiment, in order to solve the communication problem when the satellite signal is blocked, a Beidou relay station, Beidou positioning communication terminal, and a message communication system and method when the navigation satellite signal is blocked are proposed. The system includes two devices (Beidou relay station, Beidou positioning communication terminal) and a set of software (multi-mode multi-system information processing software).

[0039] Beidou relay station: Figure 2 As shown, the Beidou relay station in this embodiment includes a power supply battery with high performance and large capacity, multi-mode multi-system processing software, Beidou module and ultra-short wave module, Beidou module is connected to Beidou antenna, and ultra-short wave module is connected to ultra-short wave antenna, integrating Beidou RDSS communication, Beidou global message communication, and digital ultra-short wave communication functions. Beidou relay station can receive RDSS signals and global message signals broadcast by Beidou satellites, and send short message information to the command end through the L band of Beidou satellites, and can support single card or multi-card mode; Beidou relay station has the ability to receive positioning and navigation information of multiple satellite constellations; at the same time, Beidou relay station forms a local area network with Beidou positioning communication terminals within a certain range of the surrounding area through digital ultra-short waves. Data intercommunication and protocol conversion between digital ultra-short waves and Beidou short message waveforms are realized by the multi-mode multi-system information processing software in the relay station.

[0040] Beidou positioning communication terminal: It has various forms and can be flexibly selected for different scenarios, such as Figure 3 As shown, it includes: basic Beidou positioning and communication terminal, regional Beidou positioning and communication terminal and global Beidou positioning and communication terminal. Among them, the basic Beidou positioning and communication terminal includes: intelligent display and control platform, ultra-short wave module, multi-mode multi-system information processing software, and Beidou module, which has the functions of compatible positioning and digital ultra-short wave communication; the regional Beidou positioning and communication terminal includes: intelligent display and control platform, ultra-short wave module, multi-mode multi-system information processing software and Beidou module, which has the functions of Beidou RDSS short message communication, compatible positioning and digital ultra-short wave communication; the global Beidou positioning and communication terminal includes: intelligent display and control platform, ultra-short wave module, multi-mode multi-system information processing software and Beidou module, which has the functions of Beidou RDSS short message communication, global short message communication, compatible positioning and digital ultra-short wave communication.

It is composed of modules such as link management, transceiver control, protocol processing, data cache, application interface and link drivers.

[0042] The message communication method when the navigation satellite signal is blocked includes receiving and sending communication data. The Beidou positioning communication terminal sends communication data through the relay station. Figure 4 shown.

[0043] In the first embodiment, the process of the Beidou positioning communication terminal receiving the Beidou signal from the Beidou satellite is not blocked, that is, the Beidou positioning communication terminal can be directly connected to the Beidou satellite signal. At this time, the Beidou positioning communication terminal can directly send information to the Beidou satellite in Beidou mode through the Beidou communication link, and then the Beidou satellite sends the information to the command center through the Beidou communication link.

[0044] In the second embodiment, a Beidou relay station is introduced to cooperate with a Beidou positioning communication terminal. At this time, the Beidou positioning communication terminal sends an ultra-short wave signal to the Beidou relay station via an ultra-short wave link. After the Beidou relay station receives the signal, the multi-mode multi-system information processing module converts the ultra-short wave signal into a Beidou signal. The Beidou relay station then sends the Beidou signal to the Beidou satellite via the Beidou communication link, and the Beidou satellite sends the signal to the command center via the Beidou communication link.

[0045] In another embodiment, when a Beidou positioning communication terminal is in use and the satellite signal of the Beidou satellite is blocked by the surrounding environment, the Beidou positioning communication terminal cannot directly transmit signals with the Beidou satellite or Beidou relay station, and instead transmits information signals with the surrounding unblocked Beidou positioning communication terminals through an ultra-short wave link, and then the unblocked Beidou positioning communication terminal sends an ultra-short wave signal to the Beidou relay station in an ultra-short wave manner through the ultra-short wave link. After the Beidou relay station receives the signal, the multi-mode multi-system information processing module converts the ultra-short wave signal into a Beidou signal, and the Beidou relay station sends the Beidou signal to the Beidou satellite through the Beidou communication link, and the Beidou satellite sends the signal to the command center through the Beidou communication link. Therefore, even if the Beidou signal is blocked due to surrounding environmental factors during actual use, the Beidou positioning communication terminal can send communication data to the command center.

[0046] The process of Beidou positioning communication terminal receiving communication data through relay station is as follows Figure 5As shown, in this embodiment, the command center sends the Beidou signal to the Beidou satellite through the Beidou communication link, and the Beidou satellite can send the signal directly to the Beidou positioning communication terminal through the Beidou communication link, or it can be converted through the relay station and then sent to the Beidou positioning communication terminal. When it is necessary to send a signal through the Beidou relay station, first, the Beidou satellite sends the Beidou signal to the Beidou relay station through the Beidou communication link, and the multi-mode and multi-system information processing module of the Beidou relay station converts the Beidou signal into an ultra-short wave signal, and the Beidou relay station sends the ultra-short wave signal to the Beidou positioning communication terminal through the ultra-short wave link.

[0047] The present invention proposes a Beidou relay station, a positioning communication terminal, a message communication system and method, wherein the Beidou positioning communication terminal and the Beidou relay station receive and send communication data with the command center through the Beidou satellite; the Beidou relay station and the Beidou positioning communication terminal are both processed by multi-mode multi-system information processing software. The present invention improves Beidou communication, and when the satellite is blocked, the communication data is sent to the command center by using an ultra-short wave link, and the communication is maintained without being affected by the surrounding terrain, thereby improving the reliability of Beidou communication, and the use cost is low, and ultra-short wave communication is free of charge. When it is used after installation, only the cost generated by Beidou communication needs to be paid; at the same time, a new Beidou application scenario is added, and the system and method can also be used in areas or scenarios where the satellite is severely blocked; it is easy to install, the Beidou relay station is battery-powered, wirelessly transmitted, and Beidou wireless communication does not require wiring, including power lines and data lines, and can be quickly transferred. After the operation area is changed, the Beidou positioning communication terminal and the command center can be guaranteed by moving the placement position of the Beidou relay station.
