基于组态王通讯协议的串行通讯系统的设计

Design of Serial Communication System Based on the Protocol of King View

基于单片机开发的测控产品许多都需要与上位计算机进行串行通讯,实现在上位计算机上对现场的数据实时监控。采用组态王上位监控软件的串行通讯协议,设计了基于单片机的串行通讯硬件、软件系统。经过测试,通过此串行系统上位计算机可以实时监控现场的数字输入信号、数字输出信号、模拟输入信号、模拟输出信号等数据。

Many of the measurement and control products based on single-chip microcomputers require serial communication with the upper computer,and the on-site real-time data is monitored on the upper computer.In this paper,a serial communication protocol of King View monitoring software is adopted.The serial communication hardware and software systems based on single-chip microcomputers are designed.It is proved by the experiment that the field digital input signal,digital output signal,analog input signal and analog output signal,etc.can be real time dynamically monitored through this serial communication system.
