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.
