Remote system for accurate irrigation and fertilization

Abstract

A remote system for accurate irrigation and fertilization is characterized by comprising a field environment monitoring system an irrigation subsystem and a remote monitoring system, wherein the field environment monitoring system and the irrigation subsystem are connected to the remote monitoring system by a bus; the field environment monitoring system can set working parameters of the field subsystem and monitor working states and can send information to the remote monitoring system; the remote monitoring system sends out a standard value of a soil moisture content needed by current plant growth as well as instruction information adapted to a current plant growth period according to data information such as the plant growth period, the soil moisture content and an EC value of a current irrigation area obtained by the environment monitoring system; and the information is sent to the irrigation subsystem via wireless communication.

Description

technical field [0001] The invention relates to field or greenhouse water-saving irrigation of agriculture and forestry, in particular to a remote precision irrigation and fertilization system. Background technique [0002] At present, the increasing shortage of water resources has become a global problem. Saving water and realizing efficient water use are the needs of human survival and development, as well as the needs of global economic and social development. As one of the 13 water-poor countries in the world, China's shortage of water resources has posed a serious threat to my country's economic and social development, and has even become a "bottleneck" for the continued development of the economy and society. my country is a large agricultural country, but also In a large water-poor country, the per capita water resources are about 2,300 m3, which is about 1 / 4 of the world's per capita. Among the water used in my country, agricultural water accounts for about 70% of the...

AI Technical Summary

Problems solved by technology

The control method is still mostly based on manually shutting down the water source, which is based entirely on the experience of the operator. It is not scientific and the water saving is not thorough. At the same time, it leads to a low degree of automation of the water-saving irrigation device. It is difficult to manage and labor-intensive when it is promoted in a large area. , which seriously hinders the further promotion of water-saving irrigation

At the same time, the research and application of modern irrigation devices in agriculture, forestry and horticulture is not much, and it still basically stays in manual operation. Even if automatic control devices for irrigation projects are designed and implemented in some places, it is only a small area of ​​local control. Monitoring devices for large-scale irrigation projects with extended functions are rare in my country
