Research on Accurate Irrigation Monitor and ControlSystem for Water-saving in New-typed Facility Agriculture

摘要

The system is designed aiming at the status of the rapid development of facility agriculturein recent years in China while lacking advanced and practical water-saving technologies andequipments about facility agriculture, by using soil moisture sensor, plant nutrition monitor device,accurate irrigation machine, PLC intelligent controller and computer monitor and control system, Theresources of water can be utilized perfectly and reasonably, the irrigation efficiency and waterutilization ratio can be realized the best effect.Through application of high precision sensor technology, communication technology, data-basestorage and processing technology, the system integrate measure system, irrigation equipment,plant growth, soil moisture with laws of plant growing and water needing, so the control means aremore reasonably. It can offer plant irrigation data online and can increase the outputs while savingwater, so the precise irrigation can be realized. The system possesses advantages of economic andsaving energy, easily operation and high-extent automation, it has character of innovation in Chinesefacility agriculture and can be used in greenhouses, tunnels, precise agriculture, grassland or pastureand city afforesting etc. It plays important and practical role in implementation of water-savingagriculture.
