【摘要】：为解决农田灌溉技术中存在的大水漫灌以及精准灌溉过程中控制补充不够精准,设计开发一种基于UWP(Universal Windows Platform)技术的绿色智能节水灌溉系统,利用土壤湿度的控制方式实现实时精准的灌溉,并在多种平台上运行。系统可以对土壤水分、温度及状态参数实时监测反馈,同时具有操作方便灵活,易于扩展升级和成本低、节能等特点。本文主要设计和研究结果如下:1、采用软件和硬件的方式,结合现代农业的需求,设计研发了基于UWP技术的绿色智能节水灌溉系统;并通过跨越不同平台,将移动通信设备、电脑等实时监测土壤湿度温度以及氮磷钾,实现多功能、智能化和无人值守,达到了与微软系统已接轨,并实现了无线传输,通过PS485通讯模块并建立相应的数据库模型,全面分析作物种植区域土壤水势与农田肥力相结合,实现自动实时监测与精准灌溉。试验表明,该系统通信可靠、控制准确性高、运行状态良好。2、再利用远程智能控制系统开展土壤入渗多参数节水效果试验研究方面,分析研究了基于不同压力、不同埋深的两种土壤入渗速度、湿润锋、时间等,并初步总结出不同外界条件下土壤入渗的变化规律为提高土壤水分生产力进行了有益探索。3、使用绿色智能化节水灌溉系统进行大田西瓜智能灌溉试验,对西瓜全生育期进行不同灌溉控制模式,分析研究了西瓜全生育期的形态特性以及产量和灌溉用水量,得出智能灌溉设定田间持水率的75%到田间持水率的95%比人工灌溉更节水、西瓜产量更高,为西瓜种植中灌溉管理实现自动化和信息化提供科学依据。
[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.
