Real-time agricultural irrigation monitoring and regulating system based on big data and Internet of Things

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...

Problems solved by technology

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 personal experience of agricultural water conservancy managers, and the control of irrigation based on experience cannot scientifically control irrigation according to the water demand of crops, and different crops are in different growth periods. The water demand is different. Traditional irrigation can easily lead to too much or too little water, which cannot accurately control the watering amount. The accuracy of the watering amount is poor, and it is impossible to provide the best watering amount for the crops at each growth stage. , affecting the growth of crops. At the same time, it is impossible to judge whether it is in line with the growth of crops according to the content of nutrients in the soil in the farmland. When the nutrients in the soil are deficient, the leaves of the crops will turn yellow. When there are too many nutrients in the soil , can cause seedling burn

Therefore, timely fertilization of crops plays an important role in the growth of crops. However, at present, planters only rely on experience to fertilize crops, and cannot analyze whether crops need to be fertilized according to the actual soil conditions of crops, and what kind of fertilizer is applied. The timeliness of fertilization is poor, resulting in reduced crop yields
