摘要
针对以单片机为核心的农产品仓储温湿度控制系统,从硬件和软件的思路来分析其原理,对硬件原理图和体系结构图进行了系统的描述。该系统主要功能是检测现场温湿度和温湿度越限报警,实现了温湿度的自动测量和控制,并采用PID算法,将温湿度控制在规定的范围内,通过显示器显示当前温湿度,从而达到将农产品仓储温湿度控制在最佳范围内的目的。
This system is based on single chip microcomputer as the core of the agricultural products storage temperature and humidity control system.The author analyzed its principle from the hardware and software and described the hardware principle chart and system structure chart.The main function of the system is to test the temperature and humidity and its limit alarm.The system can realize the automatic measurement and control temperature and humidity.System adopts PID algorithm,the temperature and humidity is controlled within a prescribed scope.System shows the current temperature and humidity through the display so as to produce agricultural products storage temperature and humidity control in the best range.
