基于 WSN 的智能温室大棚自动定点喷灌系统
Intelligent Greenhouse Automatic Designated Sprinkler System Based on WSN
摘要
Abstract
For the low level intelligence and automation problem of traditional greenhouse irrigation , the intelligent green-house automatic designated sprinkler system which is composed of monitoring center host PC , temperature and humidity monitoring and solenoid valve control nodes , sealed storage tank pressure monitoring node , filling presses and pump con-trol node is designed .The temperature and humidity sensor is used to get the temperature and humidity of soil surface , sending them to the monitoring centre host PC after packing node ID and data through ZigBee network .Once the moni-tored humidity is lower than the pre-set value , the solenoid valve in the corresponding area is open to sprinkle , mean-while , controlling the pressure filling to keep the pressure of water tank as a constant value .Experiments show that the system can accurately obtain the soil surface temperature and humidity data , achieving designated sprinkling and automat-ic water filling of closed storage water tank .关键词
