| Abstract: | The method of ultraviolet sorbing which is used in the concentration measuring on-line of ozone based on 89C51 is studied. The components of the system,the principles of the main modules and the programming flow chart are also introduced. The digital filter technology is used to eliminate the measuring error which happens in the course of valve-switching. So the measuring precision and veracity are improved and insured. This system can achieve the closed loop control in the ozone production through communicating with the power supply system of digital control type ozone-producing device. |
