基于PLC的十字路口护栏系统设计

Crossroads Guardrail System Design Based on PLC

针对城市交通中对行人和非机动车的有效管控较为缺乏的现状,设计了基于PLC控制的十字路口护栏系统。系统配备了基于MCSG的组态设备,支持远程监控、手动调试,并易于与现有交通灯系统进行融合,可在红灯亮时自动放下护栏,有效避免行人及非机动车闯红灯、扰乱交通的现象。

This study attempted to solve the problem of inefficient control over pedestrians and non-motor vehicles in the city. Now the motor vehicles have been well managed, while the pedestrians and non-motor vehicles have not been managed with efficiency. We set up an automatic guardrail system. When the lights turned red, the system could lay down the fence to stop pedestrians; when the lights turned green, it could rise automatically. With MCGS and PLC, this system could be remotely controlled and debugged manually, thus to solve the problem of breaking traffic rules.
