摘要
介绍了以PLCS7-200作为控制器的水井/水塔式自来水自动控制系统。它不仅能实现自动供水,且具有故障自检、自动切换和报警等功能。并采用了上位机实现系统监控和实时统计。运行情况表明,系统功能齐全,性能稳定可靠,具有较强的实用性和推广价值。
An automatic tap water control system of well or cistern using PLC S7-200 as the microcomputer is introduced in this paper. It can not only supply water automatically, but also has some functions such as detecting faults automatically, switching automatically and giving an alarm and so on. In addition, using the background computer, it can implement system watching and controlling and real-time statistic. The running condition shows this system possesses complete function, steady and reliable performance, strong practicability and popular value.
