摘要
为了解决传统供水系统所出现的响应迟缓、控制精准度欠佳等问题。在本文中设计出了一套基于PLC技术的自来水管恒温恒压智能监控系统，西门子S7-200系列PLC当作控制核心，打造出一套涵盖数据采集、过程把控以及远程监控的完整解决办法。借助高精度压力传感器、温度传感器还有流量计，对管网运行参数展开实时监测，运用PID控制算法达成对水泵机组与加热装置的精确调控，保证供水压力和水温能够稳定处于设定区间内。该系统配备了由MCGS组态软件开发的监控界面，具备实时数据展示等功能。实际的测试显示，这一系统大幅提高了供水管网的控制精准度与响应速率，切实降低了能耗以及设备的损耗，拥有良好的稳定性与可靠性。研究所得成果为城市智慧水务的建设给出了经济适用的技术方案，对于推进供水系统的自动化升级有着重要的参考意义。
