Research and Development of Intelligent Short Track Circuit Device

Track circuit in telligent short circuit device adopts closed loop romagnetic loop and used constant current active detection method, which suction mode dominated by fercan not restricted by the direction of track circuit sending and receiving. The application of digital filtering techniques reduced the interference of AC track circuit on the accuracy of short circuit detection of the shunt line. Using the technology of software and hardware, the online condition test function of shunt line was realized to thoroughly eliminated the hidden dangers in the shunt protection of track circuit.
