【摘要】：农业的增产、优质、高效离不开灌溉,国家农业的发展也主要依靠于灌溉。多年的实践证明,在农作物增产以及适量适时节水技术的应用研究方面,墒情的监测预报发挥着极其重要的作用。在我国,由于土壤墒情监测站少,导致墒情信息紧缺。为改善上述现状,加强灌区信息化、农业信息化发展,在对墒情信息的实时远程采集上,有着迫切的要求。如何高效、实时的收集土壤墒情数据,对灌区作出墒情预测,并及时采取相应的措施,成为急需解决的课题。本文在对土壤墒情监测系统功能分析的基础上,设计并实现了基于地理信息系统(GIS)的土壤墒情监控系统。该系统主要实现了数据采集、数据存储查询、GIS地图显示、并能根据墒值及天气预报信息对灌溉水量进行调控。整个系统的设计过程中,我们选用了3G通信模块MU 509进行土壤墒情数据的发送和接收。将接收到的数据信息存储到SQL Server 2008数据库中,采用Visual C++6.0这个面向对象的软件开发平台进行开发,结合MapX控件,使土壤墒情信息与实际地理位置相结合,使工作人员能够方便快捷的锁定地理位置,并采用Webservice跨操作系统平台和跨编程语言的远程调用技术,实现天气预报信息的提取。最后,通过数据库中的墒情数据以及天气预报情况对土壤作出墒情预测。本系统是基于陕西省土壤墒情而设计的,经测试该系统的设计是可行的,可以实现对远程土壤信息的实时采集;在监控系统方面:墒情数据可以直观的显示在GIS地图中;根据天气预报信息和墒情信息,实现了对灌溉水量的调控。整个系统界面直观、易于操作、功能丰富,具有可行性,达到了预期的功能要求。
[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.
