【摘要】：農(nóng)業(yè)的增產(chǎn)、優(yōu)質(zhì)、高效離不開灌溉,國(guó)家農(nóng)業(yè)的發(fā)展也主要依靠于灌溉。多年的實(shí)踐證明,在農(nóng)作物增產(chǎn)以及適量適時(shí)節(jié)水技術(shù)的應(yīng)用研究方面,墑情的監(jiān)測(cè)預(yù)報(bào)發(fā)揮著極其重要的作用。在我國(guó),由于土壤墑情監(jiān)測(cè)站少,導(dǎo)致墑情信息緊缺。為改善上述現(xiàn)狀,加強(qiáng)灌區(qū)信息化、農(nóng)業(yè)信息化發(fā)展,在對(duì)墑情信息的實(shí)時(shí)遠(yuǎn)程采集上,有著迫切的要求。如何高效、實(shí)時(shí)的收集土壤墑情數(shù)據(jù),對(duì)灌區(qū)作出墑情預(yù)測(cè),并及時(shí)采取相應(yīng)的措施,成為急需解決的課題。本文在對(duì)土壤墑情監(jiān)測(cè)系統(tǒng)功能分析的基礎(chǔ)上,設(shè)計(jì)并實(shí)現(xiàn)了基于地理信息系統(tǒng)(GIS)的土壤墑情監(jiān)控系統(tǒng)。該系統(tǒng)主要實(shí)現(xiàn)了數(shù)據(jù)采集、數(shù)據(jù)存儲(chǔ)查詢、GIS地圖顯示、并能根據(jù)墑值及天氣預(yù)報(bào)信息對(duì)灌溉水量進(jìn)行調(diào)控。整個(gè)系統(tǒng)的設(shè)計(jì)過(guò)程中,我們選用了3G通信模塊MU 509進(jìn)行土壤墑情數(shù)據(jù)的發(fā)送和接收。將接收到的數(shù)據(jù)信息存儲(chǔ)到SQL Server 2008數(shù)據(jù)庫(kù)中,采用Visual C++6.0這個(gè)面向?qū)ο蟮能浖_發(fā)平臺(tái)進(jìn)行開發(fā),結(jié)合MapX控件,使土壤墑情信息與實(shí)際地理位置相結(jié)合,使工作人員能夠方便快捷的鎖定地理位置,并采用Webservice跨操作系統(tǒng)平臺(tái)和跨編程語(yǔ)言的遠(yuǎn)程調(diào)用技術(shù),實(shí)現(xiàn)天氣預(yù)報(bào)信息的提取。最后,通過(guò)數(shù)據(jù)庫(kù)中的墑情數(shù)據(jù)以及天氣預(yù)報(bào)情況對(duì)土壤作出墑情預(yù)測(cè)。本系統(tǒng)是基于陜西省土壤墑情而設(shè)計(jì)的,經(jīng)測(cè)試該系統(tǒng)的設(shè)計(jì)是可行的,可以實(shí)現(xiàn)對(duì)遠(yuǎn)程土壤信息的實(shí)時(shí)采集;在監(jiān)控系統(tǒng)方面:墑情數(shù)據(jù)可以直觀的顯示在GIS地圖中;根據(jù)天氣預(yù)報(bào)信息和墑情信息,實(shí)現(xiàn)了對(duì)灌溉水量的調(diào)控。整個(gè)系統(tǒng)界面直觀、易于操作、功能豐富,具有可行性,達(dá)到了預(yù)期的功能要求。
[Abstract]:Agricultural production, high-quality, high-efficiency can not be separated from irrigation, the development of national agriculture also mainly depends on irrigation. It has been proved by practice for many years that the monitoring and forecasting of soil moisture plays an extremely important role in the application research of crop yield increase and proper amount of timely water saving technology. In our country, the soil moisture monitoring station is few, resulting in the shortage of soil moisture information. In order to improve the present situation, strengthen the informatization of irrigation district and develop the information of agriculture, there is an urgent need for the real-time remote collection of soil moisture information. How to collect soil moisture data in real time, how to forecast soil moisture in irrigation area, and how to take corresponding measures in time has become an urgent problem. Based on the analysis of the function of soil moisture monitoring system, a soil moisture monitoring system based on (GIS) is designed and implemented in this paper. The system mainly realizes data acquisition, data storage and query GIS map display, and can adjust and control irrigation water quantity according to soil moisture value and weather forecast information. In the whole system design process, we choose 3G communication module MU 509 to send and receive soil moisture data. The received data information is stored in the SQL Server 2008 database, and the object oriented software development platform Visual C 6.0 is used to develop the data. Combining with the MapX control, the soil moisture information is combined with the actual geographical location. It enables the staff to lock the geographical location conveniently and quickly, and adopts the remote call technology of Webservice cross-operating system platform and cross-programming language to realize the extraction of weather forecast information. Finally, the soil moisture is forecasted by the soil moisture data and weather forecast in the database. The system is designed based on soil moisture in Shaanxi Province. The design of the system is feasible and can realize the real-time collection of remote soil information. In the aspect of monitoring system, the moisture data can be displayed intuitively in the GIS map. According to weather forecast information and moisture information, the regulation of irrigation water is realized. The system interface is intuitionistic, easy to operate, rich in function, feasible and meets the expected functional requirements.
