Abstract :
The characteristics of railway automatic blocking and continuous transmission lines are studied. On this basis, a fault monitoring system is designed. Monitoring units installed on lines can detect the short fault directly (when earth fault happens, “S-injection method” is applied), and send out this information to adjacent GPRS units via Radio Frequency (RF). Then adjacent GPRS units send the data to the server. Through analyzing the gathered data, the server can locate the fault section. The test and field operation indicates that this system can identify fault section accurately and rapidly, increasing both of economic and social benefits.
