摘要
本文采用西门子s7-200 PLC进行数据采集和过程控制,利用Visual Basic6.0编程软件开发摩擦试验机上位机的人机界面,通过调用串口通信控件MSComm的方法实现摩擦试验数据的实时采集.本系统能够实现试验机定时工作、报警处理,以及压力和扭矩的实时采集和动态显示.
iemens s7 - 200 PLC is used in data acquisition and process control, and Visual Basic6.0 is used to develop the HMI of friction tester on PC, and serial communication control of MSComm is used to achieve real-time data acquisition of friction test. This system can make the tester work in timer, control alarm, and realize the dynamic display and real-time acquisition of pressure and torque.
