Abstract

The invention discloses a communication method based on a Beidou signal covering device and a short message transmission device. Wherein, the method includes: receiving a short message message sent by a Beidou signal coverage device through a first communication network, and the short message message is received by the Beidou signal coverage device from a Beidou terminal; and receiving the short message message through a second communication network The above short message is forwarded to the network management center. The device is used to perform the method described above. The communication method and short message transmission device based on the Beidou signal coverage device provided by the present invention can increase the communication frequency and overcome the limitation on the length of communication messages, and improve the communication efficiency of the Beidou signal coverage device.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method based on a Beidou signal coverage device and a short message transmission device. Background technique [0002] The Beidou navigation system is a satellite navigation system independently developed by my country, which has been applied in railway communications. In addition to the navigation and positioning functions, another important function of the Beidou navigation system is short message communication. In areas covered by Beidou satellite signals, railway staff need to use Beidou terminals to communicate with the network management center through the short message function of the Beidou navigation system. However, due to the limitation of the Beidou navigation system, the short message function sends a message every minute, and the content length of the message does not exceed 80 bytes, that is, it does not exceed 40 Chinese characters. Since t...
