Title:
PANTOGRAPH REMOTE CONTROL CIRCUIT FOR UNMANNED SUBWAY TRAIN
Document Type and Number:
WIPO Patent Application WO/2020/037774
Kind Code:
A1
Abstract:
A pantograph remote control circuit for an unmanned subway train, comprising a start circuit of an auxiliary inverter emergency start relay (3), a control circuit of an auxiliary inverter electrifying relay (7), and a start circuit of a pantograph lifting relay (10). A first normally open contact of the pantograph lifting relay is connected to a storage battery output end after being connected in series to a pantograph lifting electromagnetic valve. The control circuit effectively avoids the occurrence of storage battery feeding during operation of a train, in which situation the train cannot be activated and thus a train start failure is caused, thereby reducing train rescue and improving availability; furthermore, during storage battery feeding, bootstrap is remotely controlled by an ATC internal awakening module, without in-place operation by a driver, so that the time for operation by the driver is saved, and the error likely to be caused by the driver is reduced. The control circuit can be popularized to existing full-automatic unmanned pantograph control circuits for rail transit, such that remote emergency pantograph lifting can be achieved without manual in-place intervention, and thus a full-automatic unmanned subway is truly achieved.
