自来水二级供水系统改造

分析了自来水二级供水系统存在的问题和急需改造的环节，介绍了针对这些改造环节的系统电路设计及实施。本系统以单片机为核心，通过传感器对供水系统的各个部分进行检测和监控，单片机根据采样数据进行分析判断，发出执行机构的控制信号或报警信号。液晶显示器可以实时显示蓄水库的进水情况、水塔水位、水泵的工作情况，使供水系统安全自动地运行。

Transformation of the Secondary Tap Water Supply System

This paper analyzes some problems existing in the secondary tap water supply system and some links urgently need to be transformed, and introduces the design and implementation of the system circuit in the light of these transformed links,. This system, which takes the single-chip as the core,detects and monitors all parts of the water supply system through the sensors, the single-chip makes analysis and judgment based on the according to the sampled data, and then sends control signals or alarm signals of the executing agency. And the liquid crystal display can real-time display the flooded condition of water reservoir, the water level of water towers, and working condition of water pumps, so that the water supply system can operation safely and automatically.
