农业墒情预警信息实时推送系统的设计与实现

Design and Realization of Real-time Push System for Agricultural Moisture Early Warning Information

农业墒情预警信息实时推送系统将农业墒情监测站传过来的墒情数据,包括土壤湿度、土壤温度、大气温湿度等实时数据与预警规则相绑定,并且每分钟将解析一次预警规则。如果满足预警条件,系统就会自动将预警信息及时发送到安装有与系统配套的App的Android手机终端上,同时也支持在Web页面手动编辑信息进行推送,用户点击手机通知栏即可查看消息详情,方便用户及时采取相应的应对措施。文中介绍了一种基于XMPP协议的Android Pn开源框架的实现模型,通过详细的系统设计,在此基础上运用Spring MVC框架,采用Spring定时任务技术、My SQL数据库技术、QLExpress规则引擎技术、Android开发技术等实现了该系统,包括Web端与客户端。测试结果表明,该系统满足功能要求并且运行稳定。

The system of agricultural moisture alert information real-time push bounds the soil moisture data,which includes soil moisture,soil temperature,atmospheric temperature,humidity and so on,with warning rules parsed every minute. If the warning conditions is met,the system will automatically send early warning information to the Android phone terminal installed the App. And it also supports the Web page to manually edit the information to push. The users can click on the phone notification bar to viewthe message details,which is convenient for them to take corresponding measures in time.We introduce an implementation model of Android Pn open source framework based on extensible messageing and presence protocol（ XMPP）.With the detailed system design,it is implemented by SpringMVC framework,Spring timing task technology,My SQL database technology,QLExpress rule engine technology,Android development technology and so on,including the Web side and the Android client.The test shows that the system meets the functional requirements and runs stably.
