摘要
针对温室大棚的温度控制存在很多缺点,设计了一种基于单片机的自动温度测量、加热和浇水管理系统。用TP03型热电偶来采集温度信号,通过AD7812转换器将采集到的模拟信号转换成数字信号,再利用Intel80C51BH单片机对数据进行处理和分析并发出执行指令,最后由执行电路来执行加热或喷雾作业。设计电路简单实用,实现方便,成本低,适合大面积推广。
Aiming at many disadvantages incontrolling temperature of greenhouse,this essay introduces an automatic temperature measurement,heating,and watering management system based on single chip,capturing temperature signals with TP03 thermocouple,converting analog signals into digital signals through the AD7812 converter,processing and analysing the data and issuing the command through Intel180C51BH microcontroller.
