Embodiment

[0062] Such as figure 1 A multi-mode combined Beidou deformation monitoring data processing system is shown. The system mainly includes a data management module, a data processing module, a predictive analysis module, and an early warning module.

[0063] A multi-mode joint Beidou deformation monitoring data processing method corresponding to the above system, the specific steps are as follows:

[0064] (1) Data reception and distribution: The data management module receives the Beidou monitoring data returned by each receiver on the project site through the tcp / ip protocol, and stores the data according to the site ID, project, data receiving time, data content and other fields to the database; the monitoring data of the monitoring points are transferred to the data processing module according to the item classification. The data management module sends the data of the latest epoch to the centimeter-accurate real-time calculation sub-module of the data processing module acc...

Abstract

The invention provides a multi-mode combined Beidou deformation monitoring data processing system and method. The system mainly comprises a data management module, a data processing module, a prediction analysis module and an early warning module, wherein the data processing module comprises a centimeter precision real-time resolving sub-module and a millimeter high-precision delay resolving sub-module. According to the method, the resolving modules with two precisions are used for resolving at the same time, the two resolving modules have a relation, the baseline length constraint informationcan be provided for the delay resolving through the real-time resolving, and the ambiguity fixing rate of a multi-baseline resolving module is increased; the deformation information can be checked and judged according to a deformation point ID provided by the real-time solution through the delay solution, so that the stability of a real-time result is improved, and part of gross error values areeliminated. On one hand, the delay solution can provide a high-precision solution result, on the other hand, a solution mode can be adjusted according to the real-time result, so that the timeliness of the delay result is improved, and the delay solution and the real-time solution supplement each other to improve the monitoring precision and timeliness.

Description

technical field [0001] The invention relates to the technical field of Beidou satellite navigation, in particular to a multi-mode joint Beidou deformation monitoring data processing system and method. Background technique [0002] BeiDou Navigation Satellite System (BDS) is a global satellite navigation system independently developed by my country. Compared with the GPS navigation system of the United States, Beidou navigation system satellites have many advantages such as high altitude angle, strong signal, and multiple frequency bands. With the gradual establishment and networking of the Beidou satellite navigation system, the application of Beidou in deformation monitoring is becoming more and more extensive. [0003] The basic principle of Beidou deformation monitoring is to calculate the distance between the monitoring point and the satellite by using the phase observation value received by the Beidou receiver installed at the monitoring point, and then obtain the coor...
