摘要

Modern railway automation and remote control systems are equipped with advanced self-diagnostics facilities. This article is devoted to the development of continuous technical state control of turned-off signal lamps. Application of pulse control using special pulses is proposed. The advantage of such a control circuit is its low sensitivity to the shunting effect of the signal transformer magnetizing inductance. The correct selection of the pulse parameters allows one considerable decreasing the shunting influence of the cable line capacity. It is shown that the pulse test circuit can be implemented by means of the up-to-date contactless semiconductor component base. The pulse control principles of the turned off signal lamps are discussed. An engineering solution enabling one to generate test pulses 5 ms in duration with a time interval of 200 ms is given. The signal processing principles on the control circuit output are considered. The aforementioned solution is integrated to the structure of the signal lamp control power module.
