Embodiment Construction

[0031] In order to overcome the problem that it is difficult to realize real-time monitoring and low-cost monitoring of geological disasters with the existing technology in the environment without public network, refer to figure 1 , in this embodiment, a data transmission method of the Beidou geological disaster monitoring system based on a regional ad hoc network is adopted, and the method includes the following steps:

[0032] S01, a plurality of acquisition nodes perform high-precision static calculation on the Beidou observation data of the base station and the acquisition node to obtain baseline results or coordinate values, and send the data to the relay node through the first wireless communication module;

[0033] S02, the relay node forwards the data to the next relay node or gateway node;

[0034] S03. The gateway node converts the received data into the communication format of the Beidou short message, and then sends the data to the Beidou-3 satellite through the sh...

Abstract

The invention discloses an emergency data transmission method based on a Beidou No.3 short message, and the method comprises the following steps: S01, carrying out the high-precision static calculation of Beidou observation data of a reference station and the collection nodes through a plurality of collection nodes, obtaining a baseline result or a coordinate value, and transmitting the data to a relay node through a first wireless communication module; s02, the relay node forwards the data to the next relay node or the gateway node; s03, the gateway node converts the received data into a communication format of a Beidou short message, and sends the data to a Beidou third satellite through the short message; and S04, the Beidou third satellite transmits the short message to a remote background. The problem that in the prior art, real-time monitoring and low-cost monitoring of geological disasters are difficult to achieve in the environment without a public network is solved.

Description

technical field [0001] The invention belongs to the field of address disaster monitoring, and in particular relates to an emergency data transmission method based on the Beidou No. 3 short message. Background technique [0002] At present, for emergency scenarios such as natural or man-made disasters, it is usually necessary for the operator's emergency support vehicle to build a micro communication base station on site, to realize the access of mobile users through wireless technology, to connect the monitoring equipment to the public network, and to send the positioning data through the public network. Go to the cloud platform to continue solving. [0003] In the case of poor communication environment, the public network cannot be used to access the cloud platform, and Beidou short messages need to be used for data transmission with the cloud platform. However, if the original positioning data is directly sent back to the cloud platform through Beidou short messages , bec...
