Problems solved by technology
The existing satellite communication method of the buoy is mainly to use the Inmarsat-C satellite terminal, but the non-real-time nature and certain uncertainty of the storage and forwarding method of the Maritime Satellite C station bring inconvenience to the use and other factors, and the Inmarsat is operated by Satellite systems operated and managed abroad have poor security and confidentiality, many external conditions, and high construction and maintenance costs, which are not conducive to the real-time, safe and effective transmission of marine environmental measurement data
Existing marine hydrological monitoring can only collect hydrological data on site and in a short period of time

The invention provides a marine hydrologic monitoring system based on a Beidou satellite system.The marine hydrologic monitoring system comprises a shore-based unit and a data acquisition unit.A first Beidou communication terminal is arranged on the shore-based unit, a second Beidou communication terminal is arranged on the data acquisition unit, and the shore-based unit sends instructions to the data acquisition unit and receives acquired data through the Beidou satellite system.The data acquisition unit comprises a buoy body and a plurality of acquisition array elements connected with the lower portion of the buoy body.The buoy body is provided with a buoy unit CPU master control module.The acquisition array elements are provided with acquisition unit CPU master control modules, and the buoy unit CPU master control module sends instructions to the acquisition unit CPU master control modules and receives acquired data.By means of the marine hydrologic monitoring system, far-distance marine hydrologic real-time monitoring is achieved under the long-time unattended condition, and marine environment observation data is complete and scientific.
Description
technical field [0001] The invention relates to the technical field of marine hydrological real-time monitoring, in particular to a marine hydrological monitoring system based on the Beidou satellite system. Background technique [0002] The development trend of marine environmental observation technology is fixed offshore observation system supplemented by flexible deployment of submersible (buoy) buoy system and oceanographic survey ships. The observation data transmission medium is the key to the marine environment observation system. In order to realize the real-time collection and transmission of the marine environment observation data, the current marine environment observation data transmission usually adopts communication methods such as cable (cable), short wave, GSM / CDMA, etc., while wireless transmission The widely used communication methods are all kinds of satellite systems with communication capabilities. The existing satellite communication method of the buoy...
