| 摘 要： | 应用Penman-Monteith（缩写为P-M）方程计算作物灌溉量，设计出一套温室智能滴灌控制系统。系统采用温湿度传感器采集温室内空气的温湿度，利用Penman-Monteith方程计算作物腾发量，通过单片机设定程序控制滴灌时间，控制部分采用上下位机形式，通过无线串行通信进行数据的双向传输。试验证明，该方法方便、可靠，可应用于温室的精确灌溉。

| Abstract: | This paper is intended to devise a set of intelligent drip irrigation control system by using Penman-Monteith equation to calculate the amount of crop irrigation．The system uses humidity and temperature sensors to collect air temperature and humidity in greenhouse，and employs Penman-Monteith equation to calculate crop evapotranspiration．And then MCU programme is used to control the drip irrigation time．The control part of the system adopts upper and lower computer．It delivers data in wireless serial communication．The experiment proves that this method is convenient, reliable and can be applied in precise irrigation in greenhouse． |
