Abstract: 水資源是全球最重要的資源之一,但水污染卻日益嚴重,造成生物鏈平衡被破壞。在科技日新月異的今日,雖然帶來了無限的生活便利,但也同時造就工業廢水污染的問題。通常,廢水排放集中區,都在人煙稀少之處,在現場放置分析儀器,所得到的分析數據,根本無法回傳至環境保護中心。
Water is one of the most important resources in the world; however, water pollution is increasingly serious and damages the balance of the food chain. The ever-changing technology of nowadays not only makes life infinite convenience, but also industrial wastewater pollution. In general, the concentration area of the wastewater discharge locates in sparsely populated place. To set up the analytical instruments in this kind of area, it is impossible to transfer the analytical data back to the Environmental Protection Center.

This study focuses on using the PLC of industrial communication protocol Modbus PLC as a data collector. The role of the on-site water quality analyzer is data simulator and the data collector receives data from the simulator. Furthermore, using the cellular network technology of the current 3G mobile communications technology transfers the collected data back to the environmental Protection Center. To set up the analyzer of the water quality in the waste water quality concentration area, samples are collected in 24-hour timer mode, and collect and return, is a fail-safe monitoring. Meanwhile, this can not only enhance the credibility of industrial wastewater analysis and efficiency, but also reduce the problem of industrial waste water pollution by giving the result of the reaction to the environmental protection agencies immediately. On the other hand, we can also ask the factory to improve the issue of industrial wastewater pollution over the limit or even do the evaluation of the possibility for reclamation and recycling.
