Abstract: The present disclosure relates to a passenger communication output control circuit for an unmanned metro train. The unmanned metro train is installed with passenger emergency communication units each having a communication button and a communication relay. The communication relay has a normally-closed contact pair and is linked with the communication button in a one-to-one correspondence. When the communication button is pushed down, the communication relay is energized to disconnect the normally-closed contact pair. The normally-closed contact pairs of all the coaches are connected in series to form an emergency communication circuit. Two terminals of the emergency communication circuit are respectively connected to a train power supply and an input/output module of a TCMS in the coach. When the passenger information system works normally, both a communication network and hardwire can transmit the communication signal.

Abstract: A pantograph remote control circuit for an unmanned metro train includes a startup circuit of an auxiliary inverter emergency start relay, a control circuit of an auxiliary inverter energized relay, and a startup circuit of a pantograph raising relay. A first normally-open contact pair of the pantograph raising relay is serially connected to a pantograph raising electromagnetic valve and then connected to an output terminal of a battery. At the meantime, the bootstrap is remotely controlled by the internal ATC wake-up module when the power supply is fed by the battery, and there is no need for the driver to operate on the spot, thereby saving time for the driver from operations and reducing the potential misoperation of the driver.
