Embodiment 1

[0063] figure 1 This is a flowchart of a method for controlling a platform screen door provided in Embodiment 1 of the present invention. This embodiment can be applied to the situation of controlling the safety screen door of rail transit. The method can be executed by a screen door controller. Specifically include the following steps:

[0064] S110, parse the received train instruction to obtain the task to be executed.

[0065] Among them, the train command is a command issued by the train to communicate with the platform. Usually, the train command is received by the train-to-ground signal system and forwarded to the screen door controller. After analyzing the train command, the screen door controller can obtain the task to be executed corresponding to the train command. The to-be-executed task may be: a door opening task, a door closing task, or other tasks. For example, when the train is about to enter the station, the train sends an entry instruction, and the screen...

Embodiment 2

[0083] image 3 This is a flowchart of a method for controlling a platform screen door provided in the second embodiment of the present invention. This embodiment can be applied to the situation of controlling the safety screen door of rail transit. The method can be executed by a gate control unit, and the method specifically includes: Follow the steps below:

[0084] S210. Receive the task instruction sent by the screen door controller through a hard wire, and receive the verification instruction sent by the screen door controller through a serial communication bus.

[0085] Among them, the gate control unit and the screen door controller communicate through hard wire and serial communication bus respectively for instruction transmission.

[0086]Optionally, in order to further ensure the reliability of communication between the gate control unit and the screen door controller, and to ensure that the gate control unit executes the task issued by the screen door controller, ...

Embodiment 3

[0108] Figure 4 A schematic structural diagram of a platform screen door control system provided in Embodiment 3 of the present invention, the screen door control system is typically a rail transit platform screen door control system, and the control system can execute the platform screen door provided by any embodiment of the present invention. A door control method, the control system comprises: a screen door controller 10 and a door control unit 30 connected in communication, wherein,

[0109] The screen door controller 10 is used to parse the train command to obtain the task to be executed, according to the task to be executed, send the task command to the gate control unit 30 through the hard wire, and send the verification command to the gate control unit 30 through the serial communication bus; The serial communication bus receives the task execution information of the gate control unit 30, and determines the control result of the platform screen door based on the task...

Abstract

The embodiments of the invention disclose a platform screen door control method and system. The platform screen door control method comprises the steps that a received train instruction is analyzed toobtain a target task; according to the target task, a task instruction is sent to a door control unit through a rigid line, a verification instruction is sent to the door control unit through a serial communication bus, and the verification instruction is used for indicating the door control unit to verify the task instruction; task execution information of the door control unit is received through the serial communication bus; and a control result of a platform screen door is determined according to the task execution information. A screen door controller sends the verification instruction to indicate the door control unit to verify the task instruction, the door control unit executes the corresponding task according to a verification result, a task execution result is fed back to the screen door controller through the serial communication bus, so that the screen door controller obtains an executive condition of the issued task instruction, and the operational reliability and efficiency of the platform screen door control system are improved.

Description

technical field [0001] Embodiments of the present invention relate to a rail transit screen door technology, and in particular, to a control method and control system for a platform screen door. Background technique [0002] The platform screen door control system is an essential facility for modern urban rail transit projects. It is set along the edge of the rail transit platform to isolate the track area from the platform waiting area. The platform screen door, also known as the platform door or the platform safety door, is installed on the edge of the platform of the station along the urban rail transit line, corresponding to the train door, and is an electromechanical equipment system. The opening and closing of the platform screen door is generally carried out in conjunction with the action of the train door when the train arrives at the station, providing passengers with access to and from the train. Therefore, the reliable operation of the screen door is very importan...
