THE WASTEWATER DISINFECTION SYSTEM OF UV LAMPS BASED ON CAN BUS

摘要

Based on the current situation and development of urban wastewater treatment,this paper introduces the advantages of the ultraviolet disinfection,the concept of field-bus and application of CAN bus control system in the field of municipal wastewater by using UV disinfection lamps in detail.Furthermore,the paper also gives the design of the system's network structure,hardware configuration and working principles.The system uses ARM9 as the control core of the hardware,and the fuzzy control arithmetic is used for the control of UV lamps.The practices have proved effectiveness and validity of the system.
