基于GIS的土壤墒情监测系统

A Soil Moisture Monitoring System Based on GIS

摘要:

为了高效、直观地查看土壤的墒情以对土壤进行合理的灌溉,研究分析了目前农业信息化的发展历程,设计开发了土壤墒情监测系统；该系统基于Browser/Server(B/S)模式,用基于ARM9的水分采集器作为数据采集模块,基于XAMPP(Apache+MySQL+PHP+PERL)软件集成包设计开发了监测中心模块,GSM网络作为数据传输方式；采集到的水分数据通过GSM网络传输到监测中心mysql数据库中,监测中心对数据进行处理,将处理后的数据直观的显示在Geographic Information System(GIS)上,监测人员根据GIS地图各个市、区县显示的颜色判断干旱程度,并发布预警信息；实验数据表明,该系统能够稳定采集土壤水分数据并传输到数据库中再显示在web页面,相比Client/Server(C/S)模式简化了系统的开发、维护和使用,降低了成本,解决了传统的实地查看土壤墒情的费时费力。

Abstract:

In order to efficiently and intuitively view soil moisture,the research analyzed the development of current agricultural information,designed and developed a soil moisture monitoring system. Based on Browser/Server(B/S) mode,using water-based ARM9 collector as a data acquisition module.Based on XAMPP(Apache+MySQL+PHP+PERL) software package, the system designed and developed an integrated monitoring center module, GSM network as data transimission. The collected water data was transmitted to the monitoring center Mysql database through GSM network. Then,the monitoring center processed the data and make the processed data display in Geographic Information System(GIS). According to the color displayed in the map of each city, monitoring officer determined the extent of the drought, so as to send warning messages. The experimental data showed that the system can collect soil moisture data stably, transimit it to database and display it on the web page. Compared to Client/Server(C/S) mode, it simplified the development,maintance and use of system, reduced the cost, solved the problem of time and effort consuming in tranditonal field view of soil moisture.
