摘　　要：温室大棚不受地域和环境温度的限制在现代农业技术中越来越重要。提出了一种利用单片机实现对多功能温室大棚温度实施有效检测和控制的方法,以达到棚内空气温度可调,创造适应不同植物生长需求的环境。系统以AT89S52单片机系统进行多点温度采集与控制,温度信号由AD574和温度或电压转换电路提供,温度传输采用多机通讯,主控器能对各温度检测器通过串传输线实现温度数据的传输以及显示。Greenhouse is becoming more and more important in the modern agricultural technology for its unlimitedness of the environment temperature and regions.An effective way is given to applying MCU to the measurement and temperature in greenhouse.With this system,the temperature in the greenhouse can be regulated,ultimately an artificial environment for vari- ety plant will be fabricated.The system using single-chip microcomputer system AT89S52 multi-channel temperature acqui- sition and control,provide the temperature signal with the AD574 and temperature or voltage conversion circuitry,tempera- ture transmission using multi-machine communications,master on the temperature detector string transmission lines through the implementation of temperature data transmission and display.
