Water and fertilizer integrated precision management system

Abstract

The invention provides a water and fertilizer integrated precision management system. The system comprises an environmental monitoring sensor, a central control processor, a fuzzy control algorithm device, a head controller, a coder host, a programmable controller, a wireless host, a high-precision controller, a fertilizing pump relay, a head motor relay, a remote control decoder, an electronic valve and a remote wireless decoder. The water and fertilizer integrated precision management system provided by the invention has the advantages that the intelligent degree is high, and the system is well applicable to an intelligent irrigation system of local control and remote control; the system is convenient to install, low in cost and simple to maintain and has great value in popularization and application. The system realizes automatic field management in the growth process of agricultural and forestry crops, reduces the labor cost, improves the production efficiency and realizes modernization of the agriculture and forestry.

Description

technical field [0001] The invention belongs to the field of automatic management of agricultural production, and in particular relates to an integrated fine management system of water and fertilizer. Background technique [0002] In the field of agriculture, there are common vegetable cultivation bases, flower and plant cultivation gardens, etc., but at present in my country’s gardens, vegetable cultivation basically relies on manual operations, and field management during the crop growth period and later sales of vegetables require direct manual participation, such as the growth process of agricultural and horticultural plants The irrigation and fertilization work in the field is manually judged and implemented, but the shortcomings of manual base fertilizer and top dressing are as follows: [0003] The fertilizer effect of the base fertilizer is released slowly, which is not conducive to regulating the growth process of vegetables, and it is easy to cause side effects on t...

AI Technical Summary

Problems solved by technology

[0008] 1. Most of the water supply is directly connected with the conventional water supply pipe network, and the working water pressure of the irrigation system is easy to fluctuate and unstable;

[0009] 2. Although some systems are equipped with special fertilization equipment such as fertilization tank or fertilizer injection pump "Venturi tube", it is not easy to fertilize when the water pressure is low and unstable. In addition, there are many operating procedures, and farmers are generally unwilling to use it;

[0010] 3. The introduction of foreign proportional fertilizer suction devices requires a certain pressure on the pipe network during work, and the cost is high, about 1,500 yuan each, which is difficult to promote;

[0011] 4. Most of the irrigators, such as drippers, drip irrigation pipes, infiltration, etc., are designed with high water heads and need to dissipate energy to drip water; Generally, the area of ​​greenhouses and greenhouses is small, and they tend to use random water. They need low-head drip irrigation, fertilization with water, low cost, convenient operation, and easy to control water volume. However, equipment that meets the above requirements has not yet appeared.
