基于MCGS的液位监控系统设计

The Design of the Long-distance Fluid Position System Based on AT89C51 Microcomputer

随着控制系统的发展,系统越来越复杂,需要监控的系统参数也越来越多。同时为了减少现场环境对人身的伤害,要求控制人员最好能远离现场。由此产生了一系列组态软件,编写上位机监控软件,进行远程监控。介绍了基于MCGS和单片机的远程液位监控系统的硬件和软件设计。此系统采用主从式结构,上位机采用MCGS组态软件实现监控软件,对液位信息进行实时监控;下位机以单片机为核心,进行液位信息的采集和转换,并与上位机进行信息交互;上位机和下位机通过串口方式进行通信。

Along with the controlling system development, systems are more and more complicated. More and more system parameters need to be monitored. To reduce the hurt from scene environment, the system requires the workman far from the scene environment. In this way a series of configuration software are produced to exploit monitoring software of upper PC. This article introduced with emphasis the hardware and software design in the long-distance fluid position system based on the single chip and MCGS. This system uses principal and subordinate structure, the MCGS software carries on the real-time monitoring to the fluid position information; the lower position machine takes the single chip as a core, gathering and transforming the fluid position information. The upper position machine and the lower position machine communicate through the serial port.
