基于单片机的温室自动控制系统设计

温度、湿度和CO2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 Measurement and Control System Used in Agricultural Greenhouse Based on Single-chip Controller

Temperature, humidity and thickness of CO2 have an important effect on the crops. Based on fuzzy control theory and computer control technology, the working principle and main functions of the intelligent greenhouses with distributed control system 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 is accord with the reality of agricultural production of our country and is considered suitable to agricultural greenhouse and it can reach producing requirements, low-- cost and high -- reliability.
