為了實現工業廢水實時監測任務，本文給出了一種基于ARM7處理器LPC2138和嵌入式時
實操作系統uc／OS-II，開發出一套工業廢水指標多點數據采集系統。實現了對COD、TOC、流量、PH值等參數的實時測量，滿足了低成本、實時性好、抗干擾能力強的需要, 并且該嵌入式數據采集系統運行穩定,移植性好,適應各種工業環境。經環保局實際測試,完全滿足工業廢水實時監測的需要。

Abstract:In order to achieve real-time monitoring task of the industrial wastewater,
this paper was given an embedded real-time operating system based on ARM7 processor PC2138 and uc / OS-II, and was developed a set of data acquisition system about
industrial wastewater indicators. This system achieved a method of the real-time
measurement parameters such as COD、TOC、flow、PH value and so on, met a low-cost,
real-time, strong anti-jamming capability of the need, and the operation of this
embedded data acquisition system is stability, transplantation is good, and adapts
to various industrial environments. After tested in the EPA, this system fully meets
the real-time monitoring of industrial wastewater needs.
