【摘要】：传统搭载于电脑端的智能温室存在着造价昂贵,系统复杂不灵活,软件集成度低,用户体验差等不足。为此本文提出了一种基于Android平台的无线传感温室监控系统。系统设计包括数据管理、设备管理、软件设置以及信息发布四大部分。分别有数据图表、环境评分、专家指导、视频及拍照监控、无线设备控制、用户管理、推送管理、系统升级以及信息发布等主要功能点。温室环境因子数据由部署在温室内的传感节点采集,通过ZigBee网络经底层无线传感网络传输至云服务器数据库内,最终实现在Android客户端上的数据可视化,实现远程客户端查看温室内各项环境参数的实时数据及历史数据。在线视频功能中,温室内的图像信息由高清网络摄像头采集,信号传输稳定图像清晰占用带宽小,能够实现在3G网络带宽下即可清晰监控作物长势及病虫草害情况。功能丰富实现有语音对讲、拍照、录像等功能。通过Okhttp等方法实现数据库的管理,最终温室内智能设备能够通过屏幕按钮点击实现远程控制,基于语音识别听写功能实现了通过语音与数据库进行交互式管理进而实现远程控制温室内智能设备。为了能够实现更多接口还具有二维码扫描功能,实现丰富的外部接口和功能。系统设置模块中能够开关系统后台推送消息以及检查版本更新情况,方便用户对本应用进行管理。系统软件还进行了兼容性测试及性能测试,测试结果符合实际使用要求。两百款机型测试得出系统兼容性为100%,安装打开速度快,内存和CPU占用率低。为了确保数据的稳定性,在项目地多次实地测试数据稳定收发情况。测试得出系统数据丢包率低于0.6‰,稳定性满足系统实际温室生产要求。
[Abstract]:The traditional intelligent greenhouse on the computer side has some disadvantages, such as high cost, complex and inflexible system, low integration of software, poor user experience and so on.This paper presents a wireless sensor greenhouse monitoring system based on Android platform.The system design includes four parts: data management, equipment management, software setup and information release.There are data charts, environmental ratings, expert guidance, video and photo monitoring, wireless device control, user management, push management, system upgrade and information release and other main functional points.The greenhouse environmental factor data is collected by the sensor nodes deployed in the greenhouse, and transmitted to the cloud server database through the ZigBee network through the underlying wireless sensor network. Finally, the data visualization on the Android client is realized.Realize remote client to view the real-time data and historical data of each environmental parameter in greenhouse.In the online video function, the image information in the greenhouse is collected by the high-definition network camera, the signal transmission stability image clearly occupies the bandwidth small, can realize under the 3G network bandwidth, can clearly monitor the crop growth and the disease and the insect damage situation.The rich function realization has the speech intercom, the photograph, the video and so on function.Through Okhttp and other methods to achieve database management, the final greenhouse intelligent devices can be through the screen button click to achieve remote control,Based on the speech recognition and dictation function, the interactive management of voice and database is realized, and the remote control of intelligent equipment in greenhouse is realized.In order to realize more interfaces, it also has the function of two-dimensional code scanning, and realizes abundant external interfaces and functions.The system setup module can switch the system background push message and check the update of the version, which is convenient for the user to manage the application.The system software has also carried on the compatibility test and the performance test, the test result conforms to the actual use request.Two hundred models are tested with system compatibility of 100, quick installation and open, low memory and CPU usage.In order to ensure the stability of the data, test the data stability at the project site several times.The test results show that the packet loss rate of the system is less than 0.6 鈥，
