摘 要

臭氧正是一种可高效快速杀死病毒、病菌、病原体等的强氧化性气体,适用于非典防治的“高效杀毒臭氧发生器”一度被认为是一种优于各类消毒剂的清洁、高效、可以长期使用的杀毒工具。伴随着地铁汽车等公共交通工具和私家车的普及程度的提高,今天,车载臭氧消毒器成为车内消毒产品的首选之一。

本论文提出了在车载环境下使用单片机控制消毒器工作系统的设计方案。

本设计采用车载24V直流稳压电源供电,由电源模块产生5V和12V电压分别供给单片机和信号放大电路,经过单片机PWM信号控制产生一个高频电流,经过变压器作用产生瞬间2K-3KV的高压,作用于臭氧发生芯片,产生具有高效杀菌消毒的刺激性气味气体--臭氧。同时,利用单片机程序控制其工作时间周期,控制整个系统产生臭氧的时间和浓度。此外,由臭氧发生片反馈电流反馈给单片机I/O口,有程序设计起到过流保护,使得这个系统更为安全可靠!

ABSTRACT

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!
