摘　　要：针对墙板自动化生产线中模具车在行走以及养护排队过程中的碰撞问题,在单片机及PLC硬件平台上开发了模具车智能测距及防碰撞系统。该系统采用超声波测距模块进行距离信息的采集,并实时地传送给单片机,经单片机处理后,将距离显示在LCD上,并利用LED灯对不同的距离范围进行不同的信号预警,同时通过PLC及变频器控制电机,实现模具车制动以及在养护系统中较为精确距离定位,防止发生碰撞。实验验证表明:该系统有效地解决了模具车的碰撞问题,可确保墙板生产的安全性和可靠性,且成本低。An intelligent measuring and anti-collision system is developed based on MCU and PLC, no overcome collision problems during AGV （Automated Guided Vehicle） moving and lining up in produc, tion line of wallboard. Ultrasonic module is used to measure the distance between mould AGVs and signals are processed by MCU. Then real-time distance values are shown in LCD. Alarm signals are also displayed in LED according to different distances. Braking and precision positioning are controlled by PLC and frequency transformer. Experimental validation shows that this system is reliable and costs lower, it ean solve the collision problems in wallboard production effectively.
