【摘要】：為解決農(nóng)田灌溉技術(shù)中存在的大水漫灌以及精準灌溉過程中控制補充不夠精準,設(shè)計開發(fā)一種基于UWP(Universal Windows Platform)技術(shù)的綠色智能節(jié)水灌溉系統(tǒng),利用土壤濕度的控制方式實現(xiàn)實時精準的灌溉,并在多種平臺上運行。系統(tǒng)可以對土壤水分、溫度及狀態(tài)參數(shù)實時監(jiān)測反饋,同時具有操作方便靈活,易于擴展升級和成本低、節(jié)能等特點。本文主要設(shè)計和研究結(jié)果如下:1、采用軟件和硬件的方式,結(jié)合現(xiàn)代農(nóng)業(yè)的需求,設(shè)計研發(fā)了基于UWP技術(shù)的綠色智能節(jié)水灌溉系統(tǒng);并通過跨越不同平臺,將移動通信設(shè)備、電腦等實時監(jiān)測土壤濕度溫度以及氮磷鉀,實現(xiàn)多功能、智能化和無人值守,達到了與微軟系統(tǒng)已接軌,并實現(xiàn)了無線傳輸,通過PS485通訊模塊并建立相應(yīng)的數(shù)據(jù)庫模型,全面分析作物種植區(qū)域土壤水勢與農(nóng)田肥力相結(jié)合,實現(xiàn)自動實時監(jiān)測與精準灌溉。試驗表明,該系統(tǒng)通信可靠、控制準確性高、運行狀態(tài)良好。2、再利用遠程智能控制系統(tǒng)開展土壤入滲多參數(shù)節(jié)水效果試驗研究方面,分析研究了基于不同壓力、不同埋深的兩種土壤入滲速度、濕潤鋒、時間等,并初步總結(jié)出不同外界條件下土壤入滲的變化規(guī)律為提高土壤水分生產(chǎn)力進行了有益探索。3、使用綠色智能化節(jié)水灌溉系統(tǒng)進行大田西瓜智能灌溉試驗,對西瓜全生育期進行不同灌溉控制模式,分析研究了西瓜全生育期的形態(tài)特性以及產(chǎn)量和灌溉用水量,得出智能灌溉設(shè)定田間持水率的75%到田間持水率的95%比人工灌溉更節(jié)水、西瓜產(chǎn)量更高,為西瓜種植中灌溉管理實現(xiàn)自動化和信息化提供科學(xué)依據(jù)。
[Abstract]:In order to solve the problem of flood flooding and precision irrigation in farmland irrigation technology, the control supplement is not accurate enough. A green intelligent water-saving irrigation system based on UWP(Universal Windows platform is designed and developed. The control mode of soil moisture can be used to realize real-time and accurate irrigation and run on various platforms. The system can monitor and feedback the soil moisture temperature and state parameters in real time and has convenient and flexible operation. The main design and research results of this paper are as follows: 1, using software and hardware, combined with the needs of modern agriculture. The green intelligent water-saving irrigation system based on UWP technology is designed and developed. And across different platforms, mobile communication equipment, computers and other real-time monitoring of soil moisture, temperature, nitrogen, phosphorus and potassium to achieve multi-function, intelligent and unattended, has reached the Microsoft system has been connected. The wireless transmission is realized. Through the PS485 communication module and the corresponding database model, the soil water potential and the farmland fertility in the crop planting area are comprehensively analyzed. Automatic real-time monitoring and precision irrigation are realized. The experiment shows that the system is reliable in communication, high in control accuracy and running in a good state of .2. Then the remote intelligent control system is used to carry out the experimental research on the soil infiltration multi-parameter water-saving effect. Two kinds of soil infiltration speed, wetting front and time based on different pressure and different burial depth are analyzed and studied. The variation of soil infiltration under different external conditions was preliminarily summarized. The experiment of intelligent irrigation of watermelon in field was carried out by using green intelligent water-saving irrigation system to improve soil moisture productivity. The morphological characteristics, yield and irrigation water consumption of watermelon during the whole growth period were analyzed and studied by using different irrigation control modes in the whole growth period of watermelon. It is concluded that intelligent irrigation can save water more than artificial irrigation to set field water holding ratio from 75% to 95%, which provides scientific basis for realizing automation and informatization of irrigation management in watermelon planting.
