基于Android的移动化工业人机交互系统设计

摘要

针对现有工业人机交互(HMI)界面存在无法移动,灵活性差等问题,设计了基于Android的移动化工业人机交互系统.系统通过设计蓝牙/RS-485网关模块,在Android智能设备与可编程逻辑控制器(PLC)之间建立可靠的数据通道,使二者能进行双向通信.基于Android的工业人机交互软件可以进行可视化的监测与图形化的控制输入,实现人机交互系统的移动化、智能化.在某热熔胶机的HMI系统上进行实验,结果证明:系统能够在设备周围的任意位置实时可靠地显示传感器数据并修改参数,提高了工业现场HMI的效率.%Aiming at problems that existing industrial human-machine interface(HMI) is immobile and has poor flexibility,mobile industrial human-machine interaction system based on Android is designed. The Bluetooth-RS485 gateway module is designed to establish reliable data channel between Android smart devices and programmable logic controller(PLC). The Android-based software is developed to provide visual data monitoring and graphical control input that implements mobile and intelligent human-machine interaction system. It is implemented in a hot melt glue machine. Experimental results show that the system can display sensor data and modify parameters at any place around the machine,improve efficiency of industrial human-machine interaction.
