Waterworks Flocculants System Based on Machine Vision and Fuzzy Control

Flocculants is one of the most important step in water treatment process, the realization of automatic dosing flocculants is remarkable characteristics in the development of waterworks in recent years. This paper puts forward a kind of low cost automatic waterworks flocculants dosing control system based on machine vision and fuzzy control. The system first collected water samples image by camera, and obtained water quality parameters through the image preprocessing, segmentation and recognition classification, then get flocculants dosage according to the parameter mapping, and finally through the fuzzy PID control and the communication between PC and PLC to realize the flocculants dosing. This system mainly has developed with the combination of software and hardware two parts, which can realize the image processing analysis and the completion of PC, PLC and electrical communication as well as realize the flocculant dosing control automatically.
