Ozone is a kind of high speed can kill viruses, bacteria, pathogens and other strong oxidizing gases, apply to SARS prevention and control of the "efficient antivirus ozone generator" was once considered to be a superior to all kinds of disinfectants for cleaning, high efficiency, long-term use canThe removal tool.With the subway cars and other modes of public transport and private cars increase in popularity, and today, car ozone sterilizer disinfecting products to become the first choice of car.
This paper proposes to use in the automotive environment, the work of SCM sterilizer system design.
This design uses a vehicle 24V DC power supply, power supply module generated by the voltage of 5V and 12V supply to the MCU, respectively, and signal amplification circuit, through the microcontroller generates a PWM signal control of high-frequency current, generated through the transformer effect of the high-pressure moment 2K-3KV, acting on the ozone-chip, resulting in highly efficient disinfection of the pungent odor - ozone.Meanwhile, the use of single chip process control of their working time period, control of the system time and ozone concentration.In addition, feedback from the ozone-chip current feedback to the microcontroller IO port, a program designed to play over-current protection, is this system more secure!
