Problems solved by technology

[0002] At present, most controllers of rail transit platform door units are controlled by PLC, which is costly, inconvenient for debugging and installation, and difficult to realize data transmission, and PLC long-distance data transmission generally uses ProfiBus bus for communication, which generally does not have electrical isolation. The current backflow is large, which may damage the PLC

Abstract

The invention relates to a rail transportation station door unit controller, which can realize various functions of functions control, status display and data communication with a station door motor driver through hardwired connection; the rail transportation station door unit controller comprises a CPU, a RS485, an input wiring terminal, an output wiring terminal and a CAN bus; the input wiring terminal and the output wiring terminal are respectively communicated and connected with the CPU through an opto-isolator; the CAN bus is communicated and connected with the CPU through an isolating module, and the CPU power supply employs isolated power. The rail transportation station door unit controller employs a completely isolated mode, the operation is safe and reliable, and the realization cost is low.

Description

technical field [0001] The invention relates to a controller, in particular to a controller for a rail transit platform door unit. Background technique [0002] At present, most controllers of rail transit platform door units are controlled by PLC, which is costly, inconvenient for debugging and installation, and difficult to realize data transmission, and PLC long-distance data transmission generally uses ProfiBus bus for communication, which generally does not have electrical isolation. Large current backflow may damage the PLC. Contents of the invention [0003] The object of the present invention is to provide a rail transit platform door unit controller for the above-mentioned problems in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a rail transit platform door unit controller, which is connected with the platform door motor driver to realize various function control, status display and ...
