【摘要】：傳統(tǒng)搭載于電腦端的智能溫室存在著造價昂貴,系統(tǒng)復(fù)雜不靈活,軟件集成度低,用戶體驗差等不足。為此本文提出了一種基于Android平臺的無線傳感溫室監(jiān)控系統(tǒng)。系統(tǒng)設(shè)計包括數(shù)據(jù)管理、設(shè)備管理、軟件設(shè)置以及信息發(fā)布四大部分。分別有數(shù)據(jù)圖表、環(huán)境評分、專家指導(dǎo)、視頻及拍照監(jiān)控、無線設(shè)備控制、用戶管理、推送管理、系統(tǒng)升級以及信息發(fā)布等主要功能點。溫室環(huán)境因子數(shù)據(jù)由部署在溫室內(nèi)的傳感節(jié)點采集,通過ZigBee網(wǎng)絡(luò)經(jīng)底層無線傳感網(wǎng)絡(luò)傳輸至云服務(wù)器數(shù)據(jù)庫內(nèi),最終實現(xiàn)在Android客戶端上的數(shù)據(jù)可視化,實現(xiàn)遠程客戶端查看溫室內(nèi)各項環(huán)境參數(shù)的實時數(shù)據(jù)及歷史數(shù)據(jù)。在線視頻功能中,溫室內(nèi)的圖像信息由高清網(wǎng)絡(luò)攝像頭采集,信號傳輸穩(wěn)定圖像清晰占用帶寬小,能夠?qū)崿F(xiàn)在3G網(wǎng)絡(luò)帶寬下即可清晰監(jiān)控作物長勢及病蟲草害情況。功能豐富實現(xiàn)有語音對講、拍照、錄像等功能。通過Okhttp等方法實現(xiàn)數(shù)據(jù)庫的管理,最終溫室內(nèi)智能設(shè)備能夠通過屏幕按鈕點擊實現(xiàn)遠程控制,基于語音識別聽寫功能實現(xiàn)了通過語音與數(shù)據(jù)庫進行交互式管理進而實現(xiàn)遠程控制溫室內(nèi)智能設(shè)備。為了能夠?qū)崿F(xiàn)更多接口還具有二維碼掃描功能,實現(xiàn)豐富的外部接口和功能。系統(tǒng)設(shè)置模塊中能夠開關(guān)系統(tǒng)后臺推送消息以及檢查版本更新情況,方便用戶對本應(yīng)用進行管理。系統(tǒng)軟件還進行了兼容性測試及性能測試,測試結(jié)果符合實際使用要求。兩百款機型測試得出系統(tǒng)兼容性為100%,安裝打開速度快,內(nèi)存和CPU占用率低。為了確保數(shù)據(jù)的穩(wěn)定性,在項目地多次實地測試數(shù)據(jù)穩(wěn)定收發(fā)情況。測試得出系統(tǒng)數(shù)據(jù)丟包率低于0.6‰,穩(wěn)定性滿足系統(tǒng)實際溫室生產(chǎn)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，
