The invention relates to a railroad bed settlement monitoring system and method based on Beidou or GPS. The method comprises: setting two reference points and a plurality of monitoring points to receive satellite signals, taking one reference point as a reference, calculating position coordinates of the second reference point and each monitoring point in a differential positioning calculation mode, taking the position of the other reference point as an error discrimination basis, and carrying out corresponding processing; calculating a current settlement value. According to the invention, twostable reference points are set to carry out error judgment and further compensate the calculation result, so that the settlement monitoring precision is improved. Two stable reference points are set,and the data of one reference point is used as the reference for calculation, so that the complexity of calculation is not increased. When general out-of-tolerance occurs, reference point switching and recalculation are performed, so that automatic fault processing is realized, and alarm processing is not needed. When serious out-of-tolerance occurs, faults are automatically processed and accumulated firstly, alarm processing is performed only when accumulated out-of-tolerance occurs, the automation degree 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 ...
