In China's agricultural production, the low efficiency of water resources and fertilizer utilization is a common problem, which limits the progress of agricultural production to a large extent, and improving the efficiency of water and fertilizer utilization is the key to promoting the rapid development of modern agriculture. To this end, Yiyi Internet of Things integrates computer technology, electronic information technology, automatic control technology, sensor technology and fertilization technology, and designs a water and fertilizer integrated intelligent control system. The system consists of three parts: environmental intelligent collection, expert knowledge base support, and water and fertilizer integrated automatic irrigation. The detailed functions are as follows:
1. Environmental intelligence collection
The system intelligently collects the temperature and humidity, PH value, EC value and environmental data of nitrogen, phosphorus and potassium in agricultural soil through sensor equipment. The intelligent collection of environmental data is the key to realize scientific water and fertilizer irrigation. Through the analysis of the collected data and the support of the system knowledge base, the demand for water and fertilizer in the growing stage of the crop can be judged.
2. Expert knowledge base support
According to the root water and fertilizer absorption rules of crops in different environments, different seasons and different growth stages, the expert knowledge base of crop water and fertilizer integrated irrigation was established. The user can combine the system to collect data on the planting environment and analyze the demand for water and fertilizer from crops, and develop a scientific automatic irrigation scheme for water and fertilizer.
3. Water and fertilizer integrated automatic irrigation
According to the irrigation opinions provided by the system expert knowledge base and the water and fertilizer demand law of each growing period of crops, by controlling the supply of water quantity and fertilizer amount, the water and fertilizer in the soil distribution layer and the crop absorption layer space supply in the same place, the module can be divided into controllers The system, the fertilizer subsystem and the irrigation subsystem are three parts. Based on the data provided by the expert knowledge base, the control subsystem sets the proportion of fertilizer, irrigation time, irrigation area and other data, and controls the multiple control nodes through the total controller to perform quantitative and timed fertilization. The fertilizer distribution subsystem sets the fertilizer distribution plan through the man-machine interface, PC or remote control interface of the host computer; the fertilizer control system realizes the control of the water pump and the fertilizer pump through the controller's control of the DC frequency converter, thereby completing the fertilizer distribution. process. The irrigation subsystem sets the control scheme through the man-machine interface of the host computer, the PC or the remote control interface to realize the irrigation of the quantitative timing area.
The integrated water and fertilizer control system combines information technology with agronomic technology to realize agricultural informationization and automation control, and completes the automatic control production management function of crop water and fertilizer integration. According to the law of crop water and fertilizer demand, fertilization and irrigation are carried out to comprehensively control and integrate the farmland water and nutrients. It has the characteristics that the fertilizer goes with the water and is beneficial to the absorption of crops. Through water-promoting and fertilizer-adjusting water, water-fertilizer coupling is realized. Comprehensively improve the efficiency of water and fertilizer use in farmland, not only save water, fertilizer, energy, and manpower, but also greatly improve the yield and quality of crops, while reducing the pollution of the application of fertilizers.
The company provides a description of the company: Yiyi Internet of Things focuses on agricultural modernization services, and has rich experience in modernization services such as intelligent planting, intelligent aquatic products, intelligent farming, and smart farming.
