The present invention relates to a railway subgrade settlement monitoring system and method based on Beidou or GPS. Two reference points and several monitoring points are set to receive satellite signals, one reference point is used as a reference, and the second reference point and each The position coordinates of the monitoring point and the position of another reference point are used as the basis for error judgment, and corresponding processing is carried out; the current settlement value is calculated. The present invention sets two stable reference points, performs error judgment, further compensates the solution result, and improves the settlement monitoring precision. The present invention sets two stable reference points, uses the data of one reference point as a reference to solve the calculation, and does not increase the complexity of the calculation; when a general out-of-tolerance occurs, the reference point is switched and recalculated to realize the automatic processing of the fault. There is no need to go through alarm processing; when there is a serious out-of-tolerance, the fault is automatically processed and accumulated first, and the alarm is processed only when the accumulated out-of-tolerance occurs. The degree of automation is high and the false alarm rate is reduced.
Description
technical field [0001] The invention relates to the technical field of railway monitoring, in particular to a system and method for monitoring railway subsidence based on Beidou or GPS. Background technique [0002] GPS (Global Positioning System) is the Global Positioning System, a satellite navigation and positioning system established by the United States. With this system, users can achieve all-weather, continuous, real-time three-dimensional navigation and positioning and speed measurement around the world; in addition, using this system , users can also perform high-precision time transfer and high-precision precision positioning. [0003] The space signal accuracy of the Beidou satellite navigation system will be better than 0.5 meters; the global positioning accuracy will be better than 10 meters, the speed measurement accuracy will be better than 0.2 m / s, and the timing accuracy will be better than 20 nanoseconds; the positioning accuracy in the Asia-Pacific region ...
