It is necessary to newly install a ground element for erasing or updating, which is disadvantageous in cost. In addition, since the reversal detection method is based on monitoring the waveform of the signal flowing in the track circuit (comparing the current waveforms of the track circuit before and after), if the signal waveform is disturbed due to the passage of a railroad crossing or the like, the polarity is reversed. However, there is a risk of erroneous detection to determine that there is no reversal of polarity. In addition, there is a problem that it does not function when there is no track circuit current (for example, when a momentary power failure occurs in the power transmitter).
