自动停车装置在长期使用中,由于设计上的原因,当接通控制盒和机车信号接收设备电源时,报警盒就报警不止。根据电路分析,当接通接收设备电源时,机车信号机红灯闪一下马上转为白灯亮,此时端子板3~#接线柱瞬时得电后就失电,端子板5~#接线柱有电,当红灯闪时,端子板3~#接线柱有电,继电器KJ得电吸合;3~#接线柱失电后,这时继电器KJ还来不及释放,端子板5~#接线柱已经有电了,于是KJ线圈又经由R_(127)、KJ_(11-12)、D_(103)通路得电,
Automatic parking device in the long-term use, due to design reasons, when connected to the control box and locomotive signal receiving device power supply, the alarm box to alarm more than. According to the circuit analysis, when the receiving equipment power is switched on, the locomotive signal flashes red immediately to turn on the white light. At this moment, the terminal board 3 ~ # terminal lose power instantaneously and the terminal board 5 ~ # terminal has Electricity, when the red light flashing, the terminal board 3 ~ # terminal with electricity, the relay KJ was energized; 3 ~ # terminal after power failure, when the relay KJ too late to release, terminal board 5 ~ # terminal already There is electricity, so KJ coil again via R_ (127), KJ_ (11-12), D_ (103) access to electricity,
