System and method for integrally and intelligently controlling water and fertilizer in field based on multi-source information fusion

Abstract

The invention relates to a system and method for integrally and intelligently controlling water and fertilizer in a field based on multi-source information fusion. The system comprises a weather forecast inquiry receiving subsystem, a weather real-time data collecting control subsystem, a cloud computing platform, a central control unit, an irrigation and fertilization control subsystem, an irrigation and fertilization state monitoring system and an online fault detection system. The system provided by the invention is an automatic control system integrated with the functions of weather forecast inquiry, crop cloud computing platform inquiry, farmland weather real-time collection, solid fertilizer rapid solution, mother solution real-time monitoring regulation, irrigation and fertilization state monitoring, online fault detection, irrigation and fertilization and remote intelligent control. According to the invention, the factors, such as, weather forecast, cloud computing platform, weather real-time collection and growth vigor of the crops in the growth process can be comprehensively considered, corresponding irrigation and fertilization decisions can be made, and thus precise irrigation and precise fertilization can be accurately realized; and the growth vigor of the crops can be described in real time, and the irrigation and fertilization can be performed according to the growth vigor of the crops.

Description

technical field [0001] The invention relates to a field water and fertilizer integration intelligent management and control system and method based on multi-source information fusion, and belongs to the technical field of water and fertilizer integration. Background technique [0002] Water and fertilizer integrated micro-sprinkler irrigation technology is a new agricultural technology that integrates micro-sprinkler irrigation and fertilization. It is a practical method that can fully combine irrigation and fertilization, save irrigation water fundamentally, and maximize fertilizer use efficiency. At present, in order to save labor and irrigation water, and improve the utilization rate of fertilizers, the integrated system of farmland water and fertilizer has gradually been applied in large fields, and it has gradually become an important trend in agricultural field production in the future. However, in actual operation, most applications mainly rely on the user's cultivat...

AI Technical Summary

Problems solved by technology

However, none of the above-mentioned patents involves the combination of weather forecast information, expert decision-making system and field environmental test data, so accurate irrigation and fertilization decisions cannot be made

And the above patents are all applicable to liquid fertilizer, which increases the cost of fertilization for the granular fertilizer commonly used in field fertilization
