轨道电路补偿电容动态检测系统研究

摘要

Railway Dynamic Detection System for compensation capacitor of track circuit not only improved the working efficiency,but also monitored the working status of the compensation capacitor of track circuit.The paper selected the integrated positioning method of GPS/DR/MM to provide the positioning information for Dynamic Detection System,utilized the adaptive federated Kalman Filtering Algorithm for multi-sensor data fusion in order to gain the optimal estimation output of the locating data.The simulated experiments could further demonstrate that the application of integrated positioning method and adaptive Kalman Filtering Algorithm could get higher precision positioning information than the single positioning method.%利用以试验车为载体的动态检测方式对轨道电路补偿电容进行检测,能够对其工作状态进行实时监控、提高现场作业效率.本文选用GPS/DR/MM组合定位方法,为动态检测系统提供定位信息,采用自适应联合卡尔曼滤波算法对多传感器数据进行融合,以获得最优估计的定位数据的输出.通过仿真实验进一步证实,这种方法可以得到比单一定位方法更高的故障点定位精度.
