【摘要】：我國是農業(yè)大國,隨著經濟和科技的飛速發(fā)展和進步,農業(yè)中的科技含量也不斷提高。如何解決不斷增漲的糧食需求量,提高作物產量,發(fā)展現(xiàn)代化農業(yè)生產,成為一個關乎人民生活以及國家命運的重要課題。溫室大棚作為我國農業(yè)重要的基礎設施,為植物提供合適的生長發(fā)育環(huán)境,在現(xiàn)代化農業(yè)生產中發(fā)揮著巨大作用�，F(xiàn)代農業(yè)的發(fā)展方向是智能化,精準化和網絡化,然而目前我國溫室大棚環(huán)境監(jiān)控系統(tǒng)普遍有兩種,一是人工監(jiān)控,這樣存在著效率低,人力成本高,不能實時監(jiān)控的問題;二是采用有線的監(jiān)控系統(tǒng),這些有線監(jiān)控系統(tǒng)存在布線困難,安裝成本高等問題。無線傳感器網絡(Wireless Sensor Network,WSN)的優(yōu)點包括:成本低、結構簡單、安全性高、效率高等。相較于現(xiàn)有的溫室大棚環(huán)境監(jiān)控系統(tǒng),本文設計了一種基于無線傳感器網絡的溫室大棚環(huán)境監(jiān)控系統(tǒng),該系統(tǒng)可實現(xiàn)無線網絡通信,溫濕度及光照強度檢測,超限報警,數(shù)據(jù)實時顯示,開關自動控制,歷史數(shù)據(jù)查詢等功能。用戶可直接在監(jiān)控中心對溫室大棚內的環(huán)境進行實時有效的監(jiān)控,有效的將溫室大棚內的環(huán)境指標控制在適當?shù)姆秶鷥取１鞠到y(tǒng)選用CC2530作為微處理器,選用溫濕度傳感器SHT11和光照強度傳感器BH1750進行數(shù)據(jù)監(jiān)測,利用ZigBee協(xié)議棧實現(xiàn)無線組網與通信,應用LabVIEW編寫上位機人機交換界面。該系統(tǒng)具有移動靈活、可擴展性強、低成本、低功耗、操作靈活的特點。測試證明,系統(tǒng)測量精度較高,控制操作穩(wěn)定,可以較好地滿足人們對溫室大棚監(jiān)控的需求。
[Abstract]:China is a large agricultural country, with the rapid development and progress of economy and science and technology, the scientific and technological content in agriculture is also increasing. How to solve the increasing demand for food, improve crop production, and develop modern agricultural production. Greenhouse greenhouse, as an important infrastructure of agriculture in China, provides a suitable environment for the growth and development of plants. It plays an important role in modern agricultural production. The development direction of modern agriculture is intelligence, precision and networking. However, at present, there are two kinds of greenhouse greenhouse environmental monitoring system in China, one is manual monitoring. In this way, there are problems such as low efficiency, high labor cost, and cannot be monitored in real time. The second is the use of wired monitoring systems. These wired monitoring systems have problems such as difficult wiring and high installation cost. Wireless Sensor Network is used in wireless sensor networks. The advantages of WSNs include low cost, simple structure, high security and high efficiency. In this paper, a greenhouse environment monitoring system based on wireless sensor network is designed. The system can realize wireless network communication, temperature, humidity and light intensity detection, over-limit alarm, real-time data display. Switch automatic control, historical data query and other functions. Users can directly in the monitoring center to the greenhouse environment real-time and effective monitoring. The environmental index in greenhouse is effectively controlled in a proper range. CC2530 is chosen as microprocessor in this system. The temperature and humidity sensor SHT11 and the light intensity sensor BH1750 are used to monitor the data, and the ZigBee protocol stack is used to realize wireless networking and communication. This system has the characteristics of flexible movement, strong expansibility, low cost, low power consumption and flexible operation. The test results show that the system has high measurement accuracy. The control operation is stable and can meet the needs of greenhouse monitoring.
