摘要
介绍了以单片机(MCU)为核心处理器的测控设备与上位机进行通信的实现过程,详细分析了Modbus通信协议。采用Proteus软件对测控设备的外围电路进行设计,并用虚拟串口驱动(VSPD)将Proteus与上位机虚拟链接,实现通讯仿真。它无需建立物理模型,节约了开发成本,有效提高开发效率,为智能测控设备的开发提供了参考。
The implementation of the communication between the host computer and the control equipment was introduced,in which the microcontroller(MCU)was employed as the core processor.The Modbus communication protocol was analyzed accordingly.The external circuit of the control equipment was designed by using the Proteus software,and the communication simulation,which linked the Proteus and the host computer,was achieved via utilizing virtual serial port driver(VSPD).It is unnecessary to establish the physical model in the process,so the development efficiency can be improved.
