摘  要
 本文主要通过对C51及硬件保护电路的开发和研究，实现对消毒柜的控制，具有时间控制、温度控制、循环工作控制等功能。
 消毒柜控制器的核心就是对磁控管进行控制。因受磁控管工作时间的限制，及针对消毒柜能够不间断的长时间使用，需对所有的磁控管进行分组循环控制。此外，温度的测量和反馈是该系统的重要组成部分之一，采用红外测温技术对其消毒物体的表面温度进行非接触测量，以达到消毒的控制。在整个控器中，其显示部分是必不可少的，通过面板显示的内容可以直接反应磁控管的工作情况、被消毒物体表面温度的情况、消毒时间等内容。对于整个设备而言，安全是必不可少的因素，在整个控制系统中设计了过欠压保护系统，过电流保护系统，过温保护系统等一系列的保护措施，能够保证在整个机器的运转过程中使其处在安全的范围内工作。

Abstract
In this paper, through the protection circuit C51 and hardware development and research, to achieve control disinfection cabinet, has time control, temperature control, circulation control and other functions work. Disinfection cabinet controller core is controlled magnetron. Magnetron work due to time constraints, and for the disinfection of uninterrupted time to counter the use of the magnetron to be conducted for cycle control. In addition, temperature measurement and feedback of the system is an important part of one, the use of infrared temperature measurement technology to its disinfection of objects non-contact surface temperature measurement, in order to achieve the control of disinfection. In the controller, the display part is essential, through the display panel can be a direct response to the work of the magnetron, the surface temperature of disinfection, the disinfection of the contents of the time. For the whole equipment,security is an indispensable factor in the design of the control system over voltage protection, over-current protection system, over-temperature protection systems, such as a series of protective measures to ensure that the entire machine functioning in work within security.
