河北农业大学信息学院本科毕业论文 题 目： 中国枣病虫害诊断系统 摘 要Android手机的普及使得一些应用软件得到了很好的推广，通常一些专家诊断系统都是通过电脑来实现，一些偏远的地区互联网并没有被覆盖，所以这就使得一些枣树病害得不到及时的治疗和防备，本文所讨论的枣病虫害诊断系统是基于以往病虫害信息和全国专家经验为一体的跨平台系统，android平台是市场最普及的应用平台，现代手机的高普及率，易用。该系统应用于android平台实现了枣病虫害诊断能够随时掌控，更方便了查询各种病态信息。本系统通过嵌入式数据库SQLite存放病虫害相关信息，使用java技术实现本系统两大功能模块。在讨论本项目之前，首先要搜集相关病虫害资料然后进一步整理；然后进行系统框架图，系统流程图的设计；然后编写代码实现每一模块功能；最后调试程序，撰写论文。由于枣病虫害诊断系统是基于android平台开发的单击系统，数据库里边的病虫害信息量受到一定的限制。但是对于一些常见的枣病虫害，此系统可以轻松的诊断此枣树的病害情况，方便工作人员进一步预防，提高枣的产量。该系统实现了按危害部位和危害时期两种枣病虫害诊断功能。关键字：枣病虫害，专家诊断系统、SQLite数据库、java技术.Abstract Due to the popularity of Android mobile phone application software is very good promotion, usually some expert diagnosis system is realized by computer, some remote areas are not covered by the Internet, so it makes a number of jujube diseases without treatment and defense timely, jujube diseases and insect pest diagnosis system in this paper is the cross platform system the pest information and the experience of experts as one based on the Android application platform, platform is the most popular modern mobile phone market, the high penetration rate, easy to use. The system is applied to the Android platform of the jujube pests diagnose can at any time control, more convenient to query various morbid information.The system through the SQLite embedded database to storage pests and diseases related information, the use of Java techn...
