Abstract：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.
