可实时监控臭氧浓度的床单位消毒机

Bed Unit Disinfection Machine with Real-time Monitoring and Control Functions of Ozone Concentration

目的研制一种床单位臭氧消毒机,提高床单位的杀菌效果。方法设计一种能实时在线检测臭氧浓度的检测系统,并通过89C51单片机控制供给臭氧发生器的电压,实现整个臭氧生产过程的闭环控制。结果消毒机具备臭氧浓度的实时监测和控制功能,使床罩内臭氧浓度保持最佳杀菌效果。结论该床单位臭氧消毒机利用臭氧熏蒸消毒,对多种细菌繁殖体和真菌都有较好的杀灭作用,对床单位实际消毒效果能达到规范的要求。

Objective To improve sterilization effect of bed unit by studying a bed unit ozone disinfection machine. Methods Having the voltage supplied to ozone generator by 89C51 chip, a measurement and control system is designed which could detect the ozone concentration in real-time online, and achieve closed- loop control of the ozone production process. Results With the real-time monitoring and control functions of the ozone concentration, this＂ disinfection machine could keep ozone concentration of bedspread in the best sterilization effect. Conclusion The bed unit ozone disinfection machine has a better effect on killing multiplication bacteria and fungi by ozone fumigation, and achieves specification requirements.
