Problems solved by technology

After searching the existing technical literature, the Chinese invention patent "a micro-spray irrigation and fertilization system integrating water and fertilizer (CN201410587147)" discloses the water-fertilization integration technology of micro-spray irrigation, and the Chinese invention patent "wheat and corn annual production variable fertilizer-water integration Irrigation system (CN201410499375)” discloses the technology of integrated water and fertilizer management of wheat and corn using micro-spray belts, and the Chinese invention patent “A water and fertilizer integration technology model suitable for northern tea gardens (CN201310000482)” discloses the use of micro-spray belts in northern tea gardens Water and fertilizer integrated management technology, but the above documents do not involve water and fertilizer integrated automatic intelligent irrigation management technology
[0004] In addition, the existing fixed sprinkler irrigation and micro-irrigation technologies require a lot of equipment and high cost; the moving function of the mobile sprinkler irrigation technology is not perfect, and often can only realize the automation of one-way movement
[0005] Most of the existing plant protection spraying machines are difficult to use on high-stalk crops such as corn. Although there are inventions of spraying machines such as high ground clearance, they generally require special tractors to pull, and ordinary tractors need to set aside special lanes , wasting arable land area
The design requirements of water-saving irrigation technology and plant protection spray technology are very different in terms of water supply equipment, piping systems, nozzles, etc., and it is difficult to use existing water-saving irrigation or plant protection spray facilities and technologies to realize automatic irrigation with integrated water and fertilizer

Abstract

The invention discloses a water and fertilizer integrated automatic irrigation management system. The system includes the following parts: a water and fertilizer integrated operation platform, which includes a water source, a fertilization system, an automatic lifting system and a filtration precipitation system; a water supply and distribution pipe network, which runs through the water and fertilizer integrated operation platform; a field irrigation system, which is connected to the end of the water supply and distribution pipe network and includes a micro-irrigation irrigation system; a first the power system, which applies water head and power to the water supply and distribution pipe network and field irrigation system, and comprises a first power pump and a drive motor; and automatic control system, which is provided with a visual operation interface and a human-computer interaction platform, and includes an irrigation automation control box and field automation control equipment; and a circuit system. A traditional micro-irrigation system and the irrigation automation control programming system are integrated, and one set of equipment can realize two functions of irrigation and fertilization, so as to reduce the management links and to improve work efficiency.

Description

technical field [0001] The invention relates to the field of water and fertilizer irrigation for field crops, in particular to a water and fertilizer integrated automatic irrigation management system. Background technique [0002] At present, grain production in many regions of my country is facing problems such as water shortage, serious waste of water and fertilizer, and labor shortage. Traditional high-yield technology often requires a lot of manpower and many management links, which cannot meet the needs of the development of modern agricultural mechanization and simplified cultivation, which seriously restricts the further development of field crop production. [0003] The water and fertilizer integrated irrigation system can coordinate the supply of water and fertilizer, greatly reduce the input of manpower and material resources, and has the advantages of saving water, labor, cost, ecology and environmental protection. After searching the existing technical literatur...
