Riverway flow monitoring method based on Beidou-3 navigation satellite system and related system thereof

Abstract

Embodiments of the invention disclose a riverway flow monitoring method based on the Beidou-3 navigation satellite system and a related system of the riverway flow monitoring method. According to themethod, original monitoring information can be obtained through a front-end sensing device, a water level gauge, a flow velocity collecting device and a camera; a telemetering terminal acquires the original monitoring information; after the original monitoring information is primarily processed, the processed original monitoring information is sent to a Beidou satellite user terminal; after the Beidou satellite user terminal further processes the original monitoring information, a processed data packet is obtained, and the processed data packet is sent to the GEO satellites of the Beidou-3 navigation satellite system in the air; and then a monitoring center acquires the processed data packet transmitted by the GEO satellites of the Beidou-3 navigation satellite system, so the real-time uploading of the monitoring result of a remote river channel is realized. Moreover, the monitoring result in the invention not only comprises water level and flow velocity results, but also comprises thesynchronous image of a flow measurement area, so the reliability of the online monitoring result of the river channel flow is higher.

Description

Technical field[0001]The present invention relates to the field of communication technology, in particular to a method for monitoring river flow based on Beidou-3 satellite and its related system.Background technique[0002]Beidou satellite navigation system (hereinafter referred to as Beidou system) is a global satellite navigation system independently constructed and operated by my country. It is an important national space-time infrastructure that provides all-weather, all-time, high-precision positioning, navigation and timing services for global users. In July 2020, the Beidou-3 system was fully completed. Compared with the wireless mobile communication mode, Beidou satellite communication based on the RadioDetermination Satellite Service (RDSS) service has a series of advantages such as wide coverage, no communication blind spots, and information transmission safety.[0003]Compared with other satellite communication methods, such as VSAT, Inmarsat-C, etc., the Beidou system has t...

AI Technical Summary

Problems solved by technology

In remote rivers such as mountains and valleys, the construction density of communication base stations is low and there are many occlusions, resulting in large-scale communication blind spots. Although connections can be established through wireless bridges, etc., there are poor anti-interference capabilities, limited communication distances, and inter-station requirements. A series of deficiencies such as visibility and high cost of setting up stations have affected the real-time upload of online monitoring results of river flow, and cannot meet the urgent needs of river and lake flow and other water and rain information for water environment governance and restoration work such as the Yangtze River Great Protection.
