Abstract
The invention discloses a real-time agricultural irrigation monitoring and regulating system based on big data and the Internet of Things. The real-time agricultural irrigation monitoring and regulating system based on big data and the Internet of Things comprises a data collecting module, a data processing module, an image collecting module, an image processing module, an image feature analyzingmodule, a manual input module, a storage database, a cloud server, an irrigation coefficient analyzing module, an irrigation execution end, a fertilization execution end and a display. According to the provided intelligent constructional engineering construction operation environment monitoring system based on big data, by collecting and processing image information of crops, analyzing the kinds and growth stages of the crops in combination with collection and processing of the soil humidity, the air temperature, the air humidity and the wind speed in farmland within various collection time periods, counting irrigation coefficients of crop soil, and then extracting the volume, corresponding to each irrigation coefficient, of water needed for irrigation per square meter according to the corresponding irrigation coefficient of the crop soil to obtain the irrigation water volume corresponding to an occupied area of the farmland, collecting and analyzing nutrient elements of the farmland soil at the same time, and supplying nutrient elements which the soil is short of in time, irrigation and fertilization integrated operation is achieved, the accuracy of the irrigation water volume andthe fertilization amount of the soil is improved, and the water requirement and the fertilization amount of the soil can be analyzed reasonably according to the current practical situations of the soil and the crops, so as to conduct intelligent irrigation and fertilization, so that waste of water resources and fertilizers and high human cost are reduced.
Description
technical field
[0001] The invention belongs to the field of big data monitoring systems, and relates to a real-time monitoring and control system for agricultural irrigation based on the big data Internet of Things. Background technique
[0002] Water is an indispensable resource for human survival. However, with the continuous development of human civilization and social progress, the shortage of water resources has become a major problem facing mankind in the 21st century. The consumption of domestic and industrial water for urban residents has increased sharply, further reducing space for agricultural water use. With the rapid development of modern agricultural greenhouse technology, the general agricultural irrigation mode generally has problems such as waste of water resources and unreasonable irrigation, which can no longer meet people's needs.
[0003] However, the irrigation used in the existing farmland automatic irrigation systems is mostly controlled by the pers...
