设施农业精准灌溉监控系统的研究与开发

该系统是针对近年我国设施农业快速发展，但缺乏先进实用的设施农业节水技术与设备而研制开发的．通过土壤水分传感器、植物营养检测系统、精准灌水机、PLC智能控制器、计算机监控等手段，充分合理利用有效水资源，从而使设施农业灌水效率和水的利用率达到最佳。系统应用高精度传感技术、通信技术、数据库存储和处理等技术，将计量系统、灌水设备、植物生长、土壤水分与作物生长规律及需水规律有机结合在一起，使调控手段更加合理，可在线提供实时作物灌溉数据，从而提高产量节省水源，实现精准灌溉，在国内设施农业领域具有创新性。系统具有经济节能、操作容易、自动化程度高的优点，可在异地随时掌握作物灌水情况，大大方便了用户。可广泛应用于温室大棚、精细农业、草地牧场、城市绿化等领域，对节水农业的实施具有重要的现实意义。

Research and Development of Facility Agriculture Precision Irrigation Monitor and Control System

The system is designed aiming at the status of the rapid development of facility agriculture in recent years in China while lacking advanced and practical water-saving technologies and equipments about facility agriculture, by using soil moisture sensor, plant nutrition monitor device, accurate irrigation machine, PLC intelligent controller and computer monitor and control system, The resources of water can be utilized perfectly and reasonably, the irrigation efficiency and water utilization ratio can be realized the best effect. Through application of high precision sensor technology, communication technology, data-base restore 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 are more reasonably. It can offer plant irrigation data online and can increase the outputs while saving water, so the precise irrigation can be realized. The system possesses advantages of economic and saving energy, easily operation and high-extent automation, it has character of innovation in Chinese facility agriculture and can be used in greenhouses, tunnels, precise agriculture, grassland or pasture and city afforesting etc. It plays important and practical role in implementation of water-saving agriculture.
