Background
Compared with the automation of the prior automatic train driving system, the automatic train driving system has higher automation, and the work of a driver or garage staff is completed before the cooperation of the train and trackside equipment. A safe and efficient garage door management scheme can effectively reduce the train warehousing time and improve the line operation capacity.
The ATP beside the track protects the safety of the train through the automatic protection of the train and the crossing area chain of the mobile authorization, and meanwhile, the ATP beside the track is convenient to manage the mobile authorization. The mobile authorization crossing chain is composed of mobile authorization crossing areas in different directions, when the mobile authorization crossing area is in a limiting state, the mobile authorization crossing area cannot cross the mobile authorization crossing area boundary, and the mobile authorization crossing area is in a non-occupied state.
The garage door needs to be closed to ensure that no movable train exists in the garage door in a certain range, and is special, when the train exists on the dormancy rail far away from garage door one side, only the check mode of judging whether the garage door can be closed is removed through the state of judging the automatic protection of the train, the condition that the door of the authorized garage is closed becomes abnormal and complicated, the efficiency of entering and exiting the garage of the train is seriously influenced, and the expandability of the system is not favorable. Such a situation often exists in garage door control systems that are driven fully automatically, for example, chinese patent publication No. CN105257141A discloses a garage door control method and system suitable for full-automatic driving, and specifically discloses that an interlock CI receives a command for opening and closing a garage door from a signal subsystem according to a receiving and dispatching plan and a dispatching operation; the interlock CI judges whether to output a garage door closing instruction according to the collected states of all garage doors, the protection access state and the train state; the interlock CI outputs a garage door opening or closing instruction to a corresponding actuating mechanism of the garage door according to a command from the signal subsystem and a judgment result of the interlock CI, aims to improve the reliability of the system operation by reducing potential safety hazards caused by human factors in train inspection and car washing processes, and judges whether the garage door can be closed only by judging the automatic protection state of the train (the state of each garage door, the protection access state and the state of the train), so that the condition of closing the authorized garage door becomes abnormal and complicated, and the efficiency of train entering and exiting is seriously influenced.
