| Summary: | 碩士 === 國立彰化師範大學 === 電機工程學系 === 104 === In order to monitor the raw water and water supply manages properly. The equipment of the deep well water source and the compressor which are send water to the user must be known. The operator needs to perambulate water purification plant, and measure the water level of the distributing reservoir manually. These data are not correct enough and data writing is clerical error thus leads to misjudgment easily. Besides, it is unable to use historical date to find out reason and to solve when the problem happened in the water purification equipment. It consumes time, manpower, and it cannot be improved. Moreover, it is not easy to monitor the implementation plan for water supply. Especially during the rains of typhoon season, it causes on the strain and leads to damage of the equipment easily. It causes the water shortage of users, the electricity blacked out and other disasters.
In this thesis, the remote monitoring system is designed. The operator uses this system to monitor the water level and pressure. These data can be used for water level analysis and obtain the water level changes accurately. This system can adjust the pump remotely, and use the backwash principle to clean sludge. When the original water flows into the rapid filter, it can process the dirty substances of the raw water. When the water pressure and clear water tank level is abnormal, it can promptly notify the operator rushed at site, and restart the backup device to avoid the water shortage of users. This system can reduce labor costs and shuttle traffic accidents significantly. After the benefit/cost analysis, it is cost effective and is worth to popularize.
