Abstract

A central redundancy control system for a rail transit platform screen door comprises a main central controller, a standby central controller, a main input-output device, a standby input-output device, a main network module and a standby network module. The main central controller and the standby central controller are connected with the main network module and the standby network module in a communication manner respectively, and are connected with the main input-output device and the standby input-output device in a communication manner respectively through the main network module and the standby network module; and the main central controller is connected with the standby central controller in a bidirectional communication manner through a synchronous cable. The two central controllers are used for realizing foreground-background simultaneous working redundancy technology, and the two input-output devices are used for realizing activated or deactivated working redundancy technology. When each of the central controllers, the input-output devices, a power module or the network modules goes wrong or fails, the system can be ensured to work normally and stably, and reliability of the system is improved.

Description

technical field [0001] The invention relates to automatic control, in particular to a central redundant control system for screen doors of rail transit platforms. Background technique [0002] The central control system of the screen door mainly accepts the opening / closing command of the external system signal, sends out the command of opening / closing the screen door after logical operation, and then transmits various processed status signals of the screen door to the external system. system. The traditional screen door central control system includes a separate central controller, a separate power supply module, a separate network module, and a separate input and output device. When the central controller fails or is abnormal, and there are no other remedial measures and inspection methods, it is easy to cause failures and errors in the screen door system, so that the real-time and reliability of the screen door system cannot be guaranteed.
