Embodiment Construction

[0015] In order to obtain a stable ozone concentration, the off-line fuzzy control is applied in the ozone generator. First, through a large number of off-line experiments, the relationship between water temperature, water pressure, air humidity, amplitude, frequency, duty cycle of high-voltage electric field and ozone concentration in ozone water is obtained; then through off-line data analysis, fuzzy control is established Finally, the system detects the changes of water temperature, water pressure and air humidity in real time, and obtains the corresponding control law according to the aforementioned mathematical model to realize the control of the high-voltage electric field.

[0016] The whole control can be divided into three parts: fuzzy controller design and realization, hardware design and realization and software design and realization

[0017] 1. Implementation of fuzzy controller design

[0018] The fuzzy controller is designed to take water temperature, water pre...

Abstract

A fuzzy control method for ozone generator includes performing a great deal of off-line experiments to obtain the relation between water temp, water pressure, air humidity, frequency and duty ratio, data analyzing to create the fuzzy control model and fuzzy cotnrol rule table, real-time measuring of water temp, water pressure and air humidity, finding out the control rule acording to said model and rule table, and using the timing device of single-chip processor for pulse control to high-voltage electric field.

Description

technical field [0001] The invention relates to a fuzzy control method of an ozone generator. Background technique [0002] At present, there are many types of ozone generating devices. Most ozone generating devices do not pay attention to the ozone concentration, which causes the ozone concentration to be unstable. If the concentration is too low, the sterilization effect is not ideal, and if the concentration is too high, it will cause harm to the human body. [0003] The Chinese patent "High Efficiency and High Concentration Ozone Generator" with the application number of 96213551.8 discloses an ozone generator. The utility model adopts two sets of electrodes, the second set of electrodes is vertically distributed to the first set of electrodes, and the power lines between the two sets of electrodes have The component perpendicular to the interface between gas and solid produces surface discharge to generate ozone. The utility model has the advantages of low energy consu...
