Embodiment Construction
[0015] Embodiments of the present invention will be explained below in conjunction with the accompanying drawings.
[0016] Such as figure 1 As shown, the pantograph remote control circuit of the unmanned subway train in this embodiment includes: the starting circuit of the auxiliary inverter emergency start relay 3, the control circuit of the auxiliary inverter energized relay 7 and the control circuit of the lifting relay 10 Start the circuit.
[0017] The starting circuit of the auxiliary inverter emergency start relay 3 includes the low-voltage detection relay 2 connected to the battery output terminal, the normally closed contact of the low-voltage detection relay connected in series to the battery output terminal, the normally open contact of the ATC wake-up module and the auxiliary inverter The emergency start relay 3 of the device.
[0018] The control circuit of the auxiliary inverter energizing relay 7 is connected in parallel with the auxiliary inverter emergency ...

The invention relates to a pantograph remote control circuit of an unmanned metro, comprises a start circuit of an emergency start relay of an auxiliary inverter, a control circuit of an electric relay of the auxiliary inverter and a start circuit of a bow-up relay, wherein the first normally open contact of the bow-up relay is connected with a pantograph bow-up electromagnetic valve in series andis connected with an output terminal of a battery. At that same time, the bootstrap of the battery feed is remotely controlled by the internal wake-up module of the ATC, the driver is not need to operate on the spot, the time of the driver operation is saved, and the driver operation error is reduced. The invention effectively avoids the occurrence of the battery feeding when the metro is running, the train is unable to be activated, the metro is unable to move the metro, the metro rescue is reduced, and the availability is increased. At present, that invention can be popularize in the fullyautomatic unmanned pantograph control circuit of the metro, and the remote emergency bow can be raise without manual local intervention, so that the fully automatic unmanned pantograph control circuitof the metro can be realized in a real sense.
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 ...
