Problems solved by technology

After these modules are released in production, it is very troublesome to upgrade and maintain internal programs
Moreover, some modules do not have an external design interface, and some modules require relatively complicated preparations even if they have an external upgrade interface.
It is not convenient to upgrade and maintain the program
Therefore, for the above-mentioned problems existing in related technologies, effective solutions have not yet been proposed

Embodiment Construction

[0021] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, the Beidou communication system includes a center, Beidou satellites, and Beidou terminal equipment. The center communicates with Beidou terminal equipment through Beidou satellites. The center includes a center upgrade management module and the Beidou terminal includes a terminal adaptation upgrade module.

[0023] Such as figure 2 As shown, the communication protocol between the center and the terminal consists of packet header, packet type, packet length, packet content, check code and packet tail.

[0024] The packet header consists of two fixed bytes, defined as 0XEA and 0XAE in hexadecimal, indicating the start flag of the packet.

[0025] The package type consists of one byte, indicatin...

Abstract

The invention discloses a method for upgrading software of Beidou terminal equipment in a Beidou communication system, which includes a central upgrade management module, a Beidou satellite and Beidou terminal adaptation and upgrading module. Taking advantage of the short message transmission characteristics of Beidou satellites, the program to be upgraded is updated to Beidou terminals through Beidou satellites, thereby completing the upgrade of Beidou terminal equipment. The invention greatly facilitates the upgrading work of the Beidou terminal equipment, and reduces the upgrading and maintenance cost of the Beidou terminal equipment.

Description

technical field [0001] The invention relates to the field of Beidou No. 2 terminal equipment, in particular to a terminal equipment with the Beidou No. 2 short message function. Background technique [0002] The Beidou-2 satellite navigation system (BD2 or Beidou-2) is a global satellite navigation system independently developed by China. By the end of 2012, there were 14 satellites serving the Asia-Pacific region, including 5 GEO satellites, 5 IGSO satellites and 4 MEO satellites. [0003] The Beidou-2 satellite navigation system mainly provides three major functions: short message communication; positioning and navigation; and timing. [0004] Beidou-2 terminal equipment usually includes ship-borne terminals, data transmission terminals, handheld terminals, and Beidou modules, etc. After these modules are released in production, it is very troublesome to perform internal program upgrade and maintenance. Moreover, some modules do not have an external design interface, an...
