Intelligent water and fertilizer management system based on big data analysis

Abstract

The invention provides an intelligent water and fertilizer management system based on big data analysis, and belongs to the technical field of control. The system comprises a cloud data center, a monitoring unit, a first communication unit and a plurality of detection units, the monitoring unit and the first communication unit are arranged on the monitoring unit, the detection units are arranged in different field parcels and comprise upper computers, alarms, display screens and control panels, first controllers, data storage units, data analysis units, big data decision making units and information retrieval units are arranged in the upper computers, and each detection unit comprises a data acquisition unit, a second controller, a second communication unit and a camera. According to the system, network monitoring management of the field parcels can be achieved, running conditions of devices in the field parcels are known in real time, running of all devices is effectively monitored, frequent in-situ inspection of managers is omitted, workload is decreased, data acquisition and big data analysis are achieved, and full-automatic control is achieved.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to an intelligent water and fertilizer management system based on big data analysis. Background technique [0002] Water resources are basic natural resources and important strategic resources. The outstanding contradiction between supply and demand of water resources in my country is still the main bottleneck of sustainable development. In 2016, the national agricultural water consumption was 376.80 billion cubic meters, accounting for 62.4% of the total water consumption, and about 90% of the total agricultural water consumption was irrigation water consumption. At present, my country's agricultural water use efficiency is not high. In 2016, the effective utilization coefficient of farmland irrigation water was 0.542, which is far from the utilization coefficient of 0.7-0.8 in developed countries, and the potential for irrigation water saving is great. Changing the tr...

Problems solved by technology

[0004] Most of the intelligent fertilizer injection systems used in my country's water-saving irrigation projects are imported products. These products can automatically and accurately implement the irrigation and fertilization process from a long distance through cable connection communication, telephone communication or radio transmission, and have good performance. But the price is expensive, and it cannot be fully applied to my country's changing environmental conditions and crop planting systems, so it is not suitable for promotion and application in my country

Some domestic manufacturers are also researching and producing intelligent fertilizer injection systems. These products can be connected with various drip and sprinkler irrigation systems to monitor soil moisture in real time and automatically irrigate according to requirements. Diagnostic agricultural expert systems are still rare, and it is impossible to remotely control the fertilizer injection system for irrigation, which limits the popularity of the fertilizer injection system to a certain extent
