Abstract

The invention is applicable to the technical field of abnormal data detection, and provides a detecting method, system and a terminal device of switch starting current, wherein the detecting method comprises: a standard curve is generated according to the switch starting current in the database; a real-time switch starting current curve taken from a microcomputer monitoring system is viewed as a curve to be tested; the number of the data points included in the standard curve and the curve o be tested are compared with each other, and then the number of data points are determined whether they are equal or not and the curve similarity is calculated according to the result of the judgment; based on the comparison between the cure similarity of the standard curve, the curve to be tested and the similarity threshold, Alpha and Beta, of the preset curve, the running state information of the switch is generated. The beneficial effect of the method is that based on the number of data points ofthe curve to be tested and the standard curve, the similarity calculation of the curve to be tested and the standard curve is divided into different calculation methods, and the calculation can be carried out at the same time, which improves the speed of the curve similarity calculation and the monitoring efficiency of the running state of the switch.

Description

technical field [0001] The invention belongs to the technical field of abnormal data detection, and in particular relates to a method, a system and a terminal device for detecting a starting current of a turnout. Background technique [0002] The main function of the turnout is to guide the running direction of the wheels to realize the train's turn and cross-line operation. It is one of the key equipment to ensure the safety and efficiency of railway transportation. The normal and stable operation of the turnout will directly affect the safety of the high-speed rail operation. Affected by the equipment itself or external factors, railway turnouts will inevitably fail. The abnormal signal of railway equipment is often a precursor to equipment failure. If it cannot be detected and dealt with early, it will pose a threat to the safety of railway transportation. [0003] At present, the computer monitoring system is mainly used to monitor the operation status of the turnout. J...
