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.
Description
technical field [0001] The invention relates to the field of pantograph-catenary monitoring, in particular to the remote control of pantographs for fully automatic unmanned subway vehicles. Background technique [0002] In the 6-group subway vehicles, 2 pantographs are installed in each train, and the DC110V control power supply of the pantograph lifting bow is provided by the train after it wakes up, and the air source is provided by the main air cylinder or auxiliary air cylinder of the train. When the control power fails, the driver needs to manually take emergency measures on the spot to solve the problem of raising the bow. With the rapid development of rail transit, more and more subway lines adopt fully automatic driverless trains, so the remote emergency control of pantographs for fully automatic driverless subway vehicles has become a problem that rail vehicles must solve. [0003] In a manned subway vehicle, after the train wakes up, when the battery power supply ...
