Low-cost multipoint safe and high-precision positioning monitoring method and system

Abstract

The invention relates to a low-cost multipoint safe and high-precision positioning monitoring system. The low-cost multipoint safe and high-precision positioning monitoring system is composed of foursubsystems of a data receiving end, a local server end, a cloud server end and a client end. At the data receiving end, satellite original data of a satellite reference station and a satellite monitoring station are separately obtained, and the satellite original data are sent to the local server end. The satellite monitoring station can obtain coordinate data of multiple point antennas by selecting one module more than once in a time sharing mode, so that the monitoring function of a GNSS board for multiple points is achieved. In the later stage, new monitoring stations or antennas can be added as required, so that intervisibility is not required between the monitoring stations, and the monitoring stations do not influence each other. Four ways is adopted in the data receiving end to sendthe data to the local server end. The local server is responsible for data format conversion, baseline calculation, data storage on original data, and the data are transmitted to the cloud server end. The cloud server end is responsible for data and instruction interaction between the local server end and the client end.

Description

technical field [0001] The invention discloses a method and system for low-cost multi-point safe high-precision positioning monitoring, especially realizes the functions of receiving and forwarding original data, calculating high-precision baseline, encrypting data transmission, and displaying and controlling the graphical interface of the client , mainly used in the fields of satellite positioning and settlement monitoring. Background technique [0002] GNSS (Global Navigation Satellite System, GNSS) has a faster positioning speed, and can be monitored automatically around the clock, and its effect is far superior to the traditional manual measurement method using optical instruments. Monitoring geological subsidence is advanced and feasible. A satellite navigation system is a system that uses satellites to achieve its own geospatial positioning. It allows a small electronic receiver to determine its position (including longitude, latitude and altitude) by receiving high-...
