摘要
阐述了AT89C52单片机的工作原理,对当前采用的恒温加热方式进行对比和分析,从生物制品和药品所用恒温室的功能和材料两方面,分析说明了恒温室的设计思路和控制方法;给出了恒温系统的设计电路和恒温控制方法。在系统控制算法中,采用分段拟合PID控制算法,实现了恒温室的恒温控制;最后,用具体实例进行了论证。
Operational principle of AT89C52 microprocessor was described.A comparison study was made on existing heating methods for thermostatic chamber.Design idea and control method for thermostatic chamber were described,with regard to functions and materials of thermostatic chamber for biological and pharmaceutical products.Circuit of the thermostatic system and its control method were presented.For system control,segmented fitting PID control algorithm was used to keep the temperature in the thermostatic chamber constant.Finally,an actual thermostatic chamber was discussed to demonstrate the feasibility of the monitor system.
