摘要
介绍现有信号检测系统对补偿电容工作状态的判定方法,并指出现有方法的不足。提出基于差分分析的补偿电容工作状态判定方法,通过对4种不同载频轨道电路区段的数据分析,验证该方法可以提高补偿电容失效判定的准确性。
The authors introduced the method to determine the working state of compensation capacitor,which is used in the existing signal inspection systems,and pointed out the deficiencies in existing methods.Furthermore,the authors proposed a new working state determining method based on differential analysis and verify that the method can improve the accuracy of compensation capacitor failure judgment through data analysis of track circuit of four different carrier frequencies.
