化ＡＦ軌道回路送受信器。[Claim for Utility Model Registration] The audio frequency signal is placed at the boundary point of each blocked section formed by dividing the track into predetermined sections, and transmitted in response to the signal appearance of the forward blocked section. An AF track circuit transmitting/receiving circuit receives the audio frequency signal via the orbit of the rear blocked section, creates a signal appearance for the rear blocked section based on this audio frequency signal, and further sends an audio frequency signal corresponding to this signal appearance to the orbit of the rear blocked section. a receiver 1 for operating indicator relays GR, YR and train detection relay TPR provided every time the audible frequency signal from the front blocked section appears; A plurality of signal oscillators OSC1, OSC2, which create frequency signals;
and a transmitter 2 having an OSC 3, and when the receiver 1 operates the indication relay corresponding to the signal manifestation of the audio frequency signal, the frequency and level of the audio frequency signal are checked for each manifestation signal. When the transmitter 2 uses a signal oscillator to create an audio frequency signal for the rear blocked section and sends it to the trajectory of the rear blocked section, the transmitter 2 determines the signal appearance of the forward blocked section. checking the signal presentation to the rear blockage section determined based on the operation of the presentation relay corresponding to the signal presentation, and the frequency and level of the audio frequency signal generated by the predetermined signal oscillator for each presentation signal; When each signal appearance matches the signal appearance determined by A microcomputerized AF track circuit transceiver characterized in that the receiver 1 and the transmitter 2 are microcomputerized so as to detect the residual voltage and output a faulty track circuit alarm when the residual voltage is above a predetermined level.
