摘要： An audio frequency track circuit device for an electrical and insulated section in a railway and a metropolitan railway is provided to easily check an error module by displaying the module which is out of order on an LCD window. A supervisor module(100) generates a control signal for an automatic conversion to a second system. An oscillation module(200) outputs a train detection frequency, a track signal frequency and a speed code to a transmitter module(300), and outputs a train detection reference frequency, and a speed code to a receiver module(600). The transmitter module outputs a receiving synchronization code to the receiver module. A tuning module(400) receives a transmission output from the transmitter module, and outputs the transmission output to a track through a minimal load maintaining unit. A band pass filter module removes a noise of an input signal received from the track, and passes a corresponding train detection frequency. The receiver module adjusts synchronization by matching the information received from the band pass filter module with the receiving synchronization code of the transmitter module. A mother board module(700) detects a temperature of an audio frequency track circuit device. A fan module(800) receives a temperature signal from the tuning module and drives a fan.
