PROBLEM TO BE SOLVED: To reduce overshooting of an output signal without deteriorating the responsiveness of control during switching.SOLUTION: Each of track circuit transmitters 1A to 1B for transmitting a signal to a track circuit 11 includes a control unit 2 for generating a signal on the basis of a command value 12 input from a host device 10, a voltage detection part 6 for detecting the voltage value of the signal transmitted to the track circuit 11, and a current detection part 8 for detecting the current value of the signal transmitted to the track circuit 11. The control unit 2 suspends, for a predetermined period of time, control processing for generating a signal from the detected voltage value and the detected current value on the basis of a control rule when a switching instruction is received from the host device 10.SELECTED DRAWING: Figure 1
【課題】制御の応答性を悪化させることなく、系切替え時における出力信号のオーバーシュートを軽減する。【解決手段】軌道回路11に信号を送信する軌道回路用送信機1A〜1Bは、上位装置10から入力される指令値12に基づいて信号を生成する制御部2と、軌道回路11に送信する信号の電圧値を検出する電圧検知部6と、軌道回路11に送信する信号の電流値を検出する電流検知部8と、を備える。制御部2は、上位装置10から系切替え指示があった場合に、検出された電圧値及び電流値から、制御則に基づいて信号を生成する制御処理を所定時間停止する。【選択図】図1
