Embodiment

[0074] like figure 1 As shown, the monitoring method of the present invention includes: Beidou receiver terminal and data collection, data transmission and analysis, Beidou real-time processing, and Beidou post-processing.

[0075] 1. Beidou receiver terminal and data collection

[0076] The Beidou receiver generally adopts the conventional measurement type Beidou receiver, and its components are as follows: figure 2 shown.

[0077]The Beidou receiver contains two key components: the antenna device and the high-precision core board. The antenna device (namely the Beidou antenna) is mainly used to collect the Beidou frequency signal in real time and send the frequency signal to the high-precision board, which is completed by the board. The signal is processed to generate the Beidou raw observation data required for data processing in the present invention. In the engineering application, the present invention can usually adopt a dual-frequency receiver, set a sampling rate ...

Abstract

The invention provides an infrastructure structure deformation monitoring method based on Beidou high-precision positioning. The method comprises four steps of Beidou satellite signal data acquisition, wireless network communication and data analysis, Beidou real-time processing and Beidou post-processing. Beidou real-time processing adopts Kalman filtering to update and estimate parameters in real time to obtain a real-time calculation result, and Beidou post-processing adopts double Kalman filtering to process the real-time calculation result and historical result data. A Beidou high-precision positioning equipment terminal is used, Beidou original data can be collected in real time, and then calculation is performed through a real-time and static post-processing algorithm and a processing flow so that real-time and post-millimeter-level deformation monitoring of infrastructure structures (such as high-rise buildings, dams, mountains, bridges and electric towers) can be realized.

Description

technical field [0001] The invention relates to the technical field of Beidou high-precision positioning, in particular to a method for monitoring deformation of infrastructure structures based on Beidou high-precision positioning. Background technique [0002] BeiDou Navigation Satellite System (BDS) is a global satellite navigation system (Global Navigation Satellite System, GNSS) developed by China itself. It is one of the four global satellite navigation systems recognized by the United Nations. (Global Positioning System, GPS), Russian GLONASS system (GLONASS) and EU Galileo system (Galileo). After the development of the first generation and the second generation, the Beidou satellite navigation system has completed the basic deployment of the third generation. It has transformed from a regional navigation and positioning system to a global navigation and positioning system, which can effectively provide high-precision real-time positioning service. [0003] Beidou-ba...
