摘要
介绍了嵌入式系统在污水COD监测方面的应用。对库仑滴定法测定COD的原理、系统软硬件总体结构、检测算法的实现作了具体阐述。找到了判断滴定终点的有效方法 ,降低了测试误差 ,有利于提高监测的准确性与可靠性。
The application of embedded system in COD monitoring of sewage is introduced. The principle of COD measurement by using Coulometry, the general structure of hardware and software, and implementation of detection algorithm are described concretely. The effective method to determine termination of titration has been found, thus the test error is eliminated and the accuracy and reliability are enhanced. Key words Environment protection Sewage monitoring Monitor of chemical oxygen demand Coulometry Embedded system
