摘要
针对脉冲电子束焊接电源系统控制相对复杂的特点,设计了以MC9S12单片机为主控芯片、触摸屏为人机交互界面的人机交互系统。通过组态软件Easy Builder 8000完成触摸屏的人机界面设计,采用模块化的编程思想完成单片机的程序设计。采用RS-485通讯接口电路,触摸屏通过Modbus协议与单片机实时通讯。试验表明,该人机交互系统能实现脉冲电子束焊接电源参数的统一管理,设置方便、界面友好、性能稳定。
According to tile complexily of tile pulsed electron beam welding （EBW） power supply system control,a set of humanmachine interaction （HMI） system based on MC9S12 microcontroller and touch screen as input and display device was developed. The HMI interface was designed hy Easy Builder 8000 configuration software and modular program was used for the microcontroller programming. The RS-485 communication interface circuit was designed and the Modbus protocol was used for the real-time communication between tire touch screen and microcontroller. Experimental results indicated that the human-machine interaction system could make the pulsed EBW power supply more convenient for parameter settings and unified management. The human- machine interaction system was user-friendly and its performance was quite stable.
