Embodiment approach 1

[0016] A humidity sensor, a carbon dioxide sensor, and an elemental nitrogen concentration sensor are placed in the sensor module at the dripper of the drip irrigation belt. Bury the drip irrigation belt into the ground as required, and the drip irrigation belt dripper is near the roots of the crops. According to the growth conditions and types of crops, set the expected target value of soil water and fertilizer. Optical fiber communication has the advantages of anti-corrosion, stability, and low cost. In this embodiment, optical fiber communication is used as the communication method between each sensor node. First, the embedded unit communicates with the sensor module at each dripper through optical fiber, obtains the soil information near the dripper from the sensor, and judges whether the preset target value is reached. Valve to adjust the ratio of water and fertilizer. After turning on for a period of time, the sensor will obtain the soil humidity, carbon dioxide concen...

Abstract

The invention discloses an intelligent control system for water and fertilizer integrated drip irrigation. The intelligent control system is characterized by comprising a drip irrigation tape band body, emitter nodes, soil property sensor module nodes near emitters, an in-drip-irrigation-tape water and fertilizer pressure sensor, a drip irrigation water input pipeline, a drip irrigation water input pipeline solenoid valve, a drip irrigation fertilizer input pipeline, a drip irrigation fertilizer input pipeline solenoid valve, an embedded module and a far-end decision host. According to the intelligent control system, related sensors are mounted at the drip irrigation tape emitters to acquire soil conditions in real time and transmit information back to the host to assist a decision maker in making the best judgment for parameters such as the water-to-fertilizer ratio, the drip irrigation amount and the like, so that the water-to-fertilizer ratio and the flow velocity are adjusted automatically, and purposes of water-saving irrigation, precise water and fertilizer integrated irrigation and the like are achieved.

Description

technical field [0001] The invention relates to a system capable of intelligently controlling integrated irrigation of water and fertilizer, which belongs to the field of agricultural water-saving machinery. Background technique [0002] As a large agricultural country in my country, improving agricultural production efficiency has always been the development direction of my country's agricultural technology. In the Guiding Opinions of the State Council on Actively Promoting the "Internet +" Action (Guo Fa [2015] No. 40), it is proposed that "in fields and regions with good foundations, the networked agricultural environment based on environmental perception, real-time monitoring, and automatic control shall be popularized. Monitoring system. In the large-scale production area of ​​agricultural products, build an agricultural Internet of things measurement and control system integrating heaven and earth, and implement precise operations such as intelligent water-saving irrig...
