Embodiment 1

[0058] like figure 2 and image 3 , is a kind of train safety door decentralization control method provided by one embodiment of the present invention, wherein, the door controller of adjacent safety door is connected through single-to-single communication serial port to form the communication chain, described method control method:

[0059] Step S100, the train controller issues a control command to the door controller at the head end of the communication chain, wherein the head end of the communication chain is the end of the communication chain connected to the train controller;

[0060] Specifically, when connecting the door controllers, the adjacent door controllers are connected one-to-one through the communication serial port, that is, when connecting, the communication link consists of the door controller and the communication serial port, and the door controllers are connected in series, and the transmission When the control command is transmitted, the door controll...

Embodiment 2

[0097] The invention also discloses a train safety door control system, such as Figure 10 As shown, the system 400 includes:

[0098] a plurality of execution units 401 for respectively controlling the operation of each safety door on the train;

[0099] a plurality of control units 402 for controlling the work of each execution unit 401 respectively, the control units 402 are connected through the communication port 403 so that each control unit 402 forms a serial communication chain;

[0100] Specifically, in this embodiment, the control unit 402 is electrically connected with the corresponding execution unit 401 through a communication port, so that the control unit 402 controls the execution unit 401 to work;

[0101] In this embodiment, the execution unit 401 may be a control motor or an integral mechanical mechanism that controls the movement of the train safety door, and the control unit 402 may be a door controller in the prior art or an information processing device...

Embodiment 3

[0103] The present invention also discloses an electronic device, the electronic device includes a processor, and the processor implements the method for decentralized control of a train safety door according to Embodiment 1 when executing the computer program stored in the memory.

Abstract

The invention relates to the technical field of train door control, in particular to a train safety door decentralization control method and system and a readable storage medium, door controllers of adjacent safety doors are connected through a one-to-one communication serial port to form a communication chain, and the method comprises the steps that a train controller issues a control command to a door controller at the head end of the communication chain; the door controller receiving the control command sends the control command to the next door controller through a one-to-one communication serial port until the control command is transmitted to the tail end of the communication chain, and the next door controller refers to the door controller which is connected with the current door controller and is close to the tail end of the communication chain; each door controller executes a control operation based on the control command; according to the invention, a decentration discrete control scheme is adopted, the end-to-end communication distance is greatly reduced, the number of communication ports only needs to support simple one-to-one, the communication signal quality is good, and the communication rate is high.

Description

technical field [0001] The invention relates to the technical field of train door control, in particular to a method, system and readable storage medium for decentralized control of a train safety door. Background technique [0002] The current control systems of high-speed rail safety gates are similar to figure 1 Structure, a central controller connects all door controllers through a communication bus, and the central controller sends instructions to control all door controllers, thereby controlling the movement, opening, and closing of the safety door. [0003] The current high-speed rail safety door control system has some defects, such as the long communication bus layout, generally more than 400 meters long, and the number of door controllers. In order to improve the signal quality during the layout process, it is necessary to use long-distance one-to-one For example, Ethernet optical fiber, due to the large number of train ports, leads to a large number of layouts, d...
