本文提出了采用89C51单片机作为控制器实现模糊PID算法控制供水系统,并且利用CAN总线技术构成的底层控制网络与监控计算机通讯,实现了楼宇供水设备的现场数据采集、传输及远程监控功能。试验表明恒压变频供水监控系统取得良好控制和监控的效果。
In this paper, 89C51 single-chip microcomputer is used as a controller to realize fuzzy PID algorithm control water supply system, and the use of CAN bus technology composed of the underlying control network and monitoring computer communication, to achieve the building water supply equipment on-site data acquisition, transmission and remote monitoring functions. Test shows that constant pressure water supply monitoring system made good control and monitoring results.
