基于串口通信的河流模型水位测量系统的设计与实现

The Design and Realization of Water Level Measurement System Based on Serial Communication

水位测量系统是基于PC机作为上位机、 4台单片机作为下位机的多机通信集散控制系统 ,文中阐述了一种新的实现上下位机间串口通信的方法 ,详细介绍了利用VC ++6 0开发的串口通信程序 ,并给出了主要源代码。经实践证明 ,系统稳定可靠。

Water level measurement system is a distributed control system with PC as epigyny computer and 4 single-chip microcomputers as hypogyny computers.In this paper,a new method to realize serial communication among epigyny computer and hypogyny computers was demonstrated,the serial communication programe developed with VC++6,0 was introduced in detail, and the primary source code was also given. It has been proved that the system is steady and reliable,also has high precision.
