摘　　要：针对温室灌溉方式落后、自动化程度低和作物成长吸水效率差等情况,将单片机控制技术应用于温室设施农业灌溉过程中,提出了一种以AT89S51单片机为核心模块的智能控制系统设计方案。该系统以传感器实测土壤水分经模数转换后的数据作为输入信号,经单片机与上位机的通信和运算处理后,输出灌溉参数实时控制继电器,实现灌溉的调控功能,达到对作物适时适量灌溉的目的。Aiming at the backward mode of greenhouse irrigation,the low degree of automation and the poor absorption of moisture in the growth of crops,a new design scheme of intelligent irrigation system is proposed.It applies the single-chip microcomputer（SMC） control technology to the greenhouse facilities agricultural irrigation and selects the AT89S51 microcontroller as the core control module.The actual measurement of soil moisture is used as the input signal of the system.After communicating between SMC and PC and operation processing of the single-chip microcomputer,the irrigation parameter is output,which acts as real time sign controlling electromagnetic valve to realize the irrigation function and achieve the efficient irrigation.
