Train door opening and closing control method, device and system

Abstract

The invention provides a train door opening and closing control method, device and system. The method comprises the following steps of: obtaining a target object, a vehicle on-plate controller (VOBC)obtains a remote door opening and closing instruction from an automatic train supervision (ATS), and the VOBC determines whether an execution condition corresponding to the remote door opening and closing instruction is met or not according to the operation state of the train, and if the operation state of the train meets the execution condition, the VOBC executes the door opening process or the door closing process according to the remote door opening and closing instruction. The operation state of a train is detected through the VOBC with a high safety integrity level, whether an execution condition corresponding to the remote door opening and closing instruction is met is determined, remote door opening and closing control is then carried out, the accuracy of judgment of the door opening and closing instruction execution condition is improved, and the problems that in the related art, whether the train meets the execution condition corresponding to the remote door opening and closing instruction or not is determined through the ATS, due to the low safety integrity level of the ATS, judgment of the remote door opening and closing execution condition is inaccurate, misoperation iscaused, and potential safety hazards are generated are solved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method, device and system for controlling the opening and closing of train doors. Background technique [0002] With the development of technologies such as computer, communication, control and system integration, fully automatic train operation is the trend of train operation in the future. When the train is in fully automatic driving mode, it needs to output relevant operation instructions to remotely control the opening and closing of the doors and screen doors. [0003] In related technologies, the remote door opening and closing operation of fully automatic trains is logically controlled by an automatic train supervision system (Automatic Train Supervision, ATS). Since the ATS is a safety integrity level (Safety integrity level, SIL) level 2 device, and The door opening and closing logic is a SIL4 level function in the on-board equipment. Therefore, there are risks i...

Problems solved by technology

[0003] In related technologies, the remote door opening and closing operation of fully automatic trains is logically controlled by an automatic train supervision system (Automatic Train Supervision, ATS). Since the ATS is a safety integrity level (Safety integrity level, SIL) level 2 device, and The door opening and closing logic is a SIL4 function in the on-board equipment. Therefore, there are risks in the remote door opening and closing condition judgment performed by the ATS, which is prone to misjudgment and potential safety hazards.
