A Beidou technology data transmission method, meteorological data transmission method and system

Abstract

The invention relates to a Beidou technical data transmission method, a meteorological data transmission method and a system. A Beidou technology data transmission method, comprising steps: S11, data sending: the message sending module performs the first analysis and the first compilation of the original message to be sent to obtain the OSM message, and after the OSM message is split , obtain a plurality of OSM sub-messages, encapsulate a plurality of OSM sub-messages into a plurality of Beidou short messages and send them to the message receiving module through the Beidou satellite; S12, data receiving: the message receiving module receives A plurality of said Beidou short messages, performing a second analysis on each of said Beidou short messages to obtain a plurality of OSM sub-messages, performing a second compilation on said OSM sub-messages to obtain a plurality of original sub-messages, and merging Generate the original message. The invention generates OSM messages on the basis of original messages according to the characteristics of detection messages, shortens message data volume, improves transmission efficiency, optimizes report compilation rules, and improves message effective information ratio.

Description

technical field [0001] The invention relates to the field of Beidou data transmission, in particular to a Beidou technical data transmission method, a meteorological data transmission method and a system. Background technique [0002] After the sounding station of the Meteorological Observatory completes a detection, it needs to compile the results of the current detection into meteorological information according to the unified code type and regulations, and transmit it to the user unit or relevant departments by wireless (or wired) telegram. According to the tasks, the sounding station needs to compile and issue two types of messages, including sounding reports and air wind reports, and send them quickly and accurately in accordance with a unified code within 30 minutes after the end of each detection. [0003] In the mobile environment in the field, it is impossible to transmit the message in time. In the actual detection business, the transmission methods of the message ...
