Design of touch-based human-machine interaction system based on programmable logic controller

串户检测装置是一户一表供电中可有效识别用户串户、反接等问题的智能装置之一。本文为用户串户检测装置设计了一个基于可编程逻辑控制器的触控式人机交互系统,以触控屏实现用户信息输入、信号启动及显示,用可编程逻辑控制器通信协议更便捷地实现可编程逻辑控制器与上位机的数据互传。试验结果表明,本文设计的交互系统数据互传准确且实时性好,触屏操作增强了人机交互操作的便利性。该系统易于实现功能扩展。

The missort fault detection device is one of intelligent devices that can effectively identify problems such as user missort fault and reverse connection in one household and one meter power supply.This paper designs a touch-based human-machine interaction system based on programmable logic controller(PLC)for user missort fault detection device,which realizes user information input,signal activation and display with touch screen.It is more convenient to realize data transmission between PLC and host computer by PLC communication protocol.The experimental results show that the data of the interactive system is accurate and real-time,and the touch screen operation enhances the convenience of human-machine interaction.At the same time,the system is easy to implement.
