Abstract
In order to achieve the automatic monitoring function of polluted water,a COD automatic monitoring system based on dsPIC and ARM9 was developed,which divides the hardware into two modules that are the system controlling module based on dsPIC chip,and the color touch screen module based on ARM9 with pre-installed WinCE system.The software design of dsPIC control system was finished,and the dynamic three-dimensional flow chart of embedded touch screen was designed.Unary linear regression which establishs the relationship between the voltage value and the COD value was proposed.The instrument has simple structure,good reliability and versatility,which can improve the speed of sewage COD monitoring,accuracy and automation.关键词
