基于单片机的温室自动控制系统设计
摘要:温度、湿度和 co 2 浓度等是影响作物生长的重要环境因子,为有效进行作
物生长的环境控制,针对日光温室的特点, 以模糊控制理论为基础,计算机控制技术为
平台,设计了一个基于模糊控制技术的计算机温室控制系统。介绍了以 PC 机为 上
位计算机, MCS 一 51 单片机为核心的智能仪表为下位机的智能温室分布式测控系
统的工作原理及主要功能。详细阐述了 该系统的软、硬件实现方法。该套控制系
统符合我国现阶段的国情且能很好地满足生产要求,成本低,运行可靠,便于推广 应
用。

Distributed Measure and Control System controlled by single-chip controller used in
Agricultural Greenhousc
Temperature, humidity and the thickness of co2 have an important effect on the
crops .In order to control such environmental factors. Based on Fuzzy control theory and
computer control technology .The working Principle and main functions of the intelligent
greenhouses with distributed control system in the Paper are introduced. This system uses
PC as a host computer and intelligent instruments with MCS-51 single-chip
microcomputers as secondary computer systems. The design methods of system hardware
and software are fully described. The system was accord with the reality of agricultural
Production of our country and was considered suitable to Agricultural Greenhouse and it
can reach Producing requirement, Low-cost and high-reliability.
KEY WORDS:intelligent greenhouse , computer distributed Auto-control system,
