  [摘  要]
 本系统采用高性能单片机智能控制系统,可实现预置要求的自动控制.通过按键可以设置时钟,时长,预设温度,设置工作状态,系统要求稳定性高,可以达到智能消毒的效果.系统实验参数在适当的数值上，可以缩短消毒时间，达到最佳消毒效果。本方案的重要部分是单片机控制系统，其主要功能是在消毒柜中的温度传感器、时种芯片将采集到的模拟量信号通过单片机采用 stc12c5412ad转成数字量信号，被单片机采用后，通过加载的程序转换后实时动态的显示自动控制消毒循环全过程。控制信号通过单片机stc12c5412ad输出至控制柜中的控制电器，采用臭氧＋紫外线双重消毒，和电热丝热风内循环烘干，使消毒更彻底，不留死角，能杀灭各种细菌和乙肝病毒。热风循环系统使柜内温度升高迅速，温度均匀，轻易烘干餐具上的水渍。其中，在整个实验中，我与福清冠捷电子有限公司的技术员一起合作，我主要担任时钟芯片DS1302的设计工作，进一步加深了对所学专业知识的掌握。

Intelligent disinfection cabinet control system
 
   [Abstract]
This system uses the high performance monolithic integrated circuit intelligence control system, may realize the initialization request automatic control. May establish the clock through the pressed key, when long, supposes the temperature in advance, the establishment active status, the system request stability is high, may achieve the intelligent disinfection the effect. The system experiment parameter in the suitable value, may reduce the disinfection time, achieves the best disinfection effect. This plan important part is the monolithic integrated circuit control system, its main function is when the disinfection cabinet temperature sensor, a kind of chip will gather the simulation quantity signal will use stc12c5412ad through the monolithic integrated circuit to transfer the digital quantity signal, after is used by the monolithic integrated circuit, through when load procedure transformation well off the dynamic demonstration automatic control disinfection will circulate the entire process. The control signal through the monolithic integrated circuit stc12c5412ad output to the control cubicle in control electric appliance, uses the ozone + ultraviolet ray dual disinfection, with heating wire hot blast internal recycling drying, causes the disinfection to be thorougher, does not keep the dead angle, can kill extinguishes each kind of bacterium and the hepatitis B virus.The heated air circulation system causes in the cabinet the temperature increment to be rapid, the temperature is even, dries on the tableware easily water-damaged. Among them, in the entire experiment, I cooperates together with the Fuqing Guanjie Electron Limited company's technicians, I mainly hold the post of clock chip DS1302 the design work, further deepened to has studied the specialized knowledge grasping.
