A comprehensive regulation and control system for water-saving irrigation in hilly areas with "wind-solar complementarity"

Abstract

The invention discloses a wind-solar hybrid comprehensive water-saving irrigation regulation system for a mountainous and hilly area. The system comprises an energy system, an irrigation system, a monitoring system, a data transmission system, a central processing system, a pipe network and power improving system, a power transmission and distribution and grid-connected generation system and an auxiliary system. By installing devices such as a wind power generation device, a solar photovoltaic power generation device, a drip irrigation device, a microspray irrigation device, a low-pressure pipe irrigation device, a soil moisture monitoring device, a crop spectrum emissivity monitoring device, a data transmission device, a CPU, a water storage tank, an ultrasonic range finder, an air compressor, a water raiser, a PVC-U agricultural irrigation pipe, an inverter, a switching room, a water source filter and a Venturi automatic fertilizer and taking a wind-solar hybrid clean energy mode as a basis, scarce water resources in the mountainous and hilly area are gathered, therefore, fixed deposit by installments is achieved, and multiple purposes of saving water, saving energy, saving fertilizer and increasing the yield are achieved while the crop irrigation requirements in the mountainous and hilly area are met.

Description

technical field [0001] The invention relates to a comprehensive control system for water-saving irrigation, in particular to a comprehensive control system for water-saving irrigation in hilly areas with "wind and scenery complementary", belonging to the technical field of clean energy and water-saving irrigation. Background technique [0002] The hilly area is a collective term for mountainous areas and hilly areas. Among them, mountainous areas mainly refer to the combination of slopes with steep and undulating surface, with an absolute height of more than 500 meters and a relative height of more than 200 meters. meters of slope complexes. Compared with the plains, due to the topography, the hilly area is prone to soil erosion under the erosion of rainwater. In addition, the hilly area is sparsely populated, the transportation is inconvenient, and it lacks basic energy, water sources and other materials and facilities. If there is no effective water-saving irrigation met...

Problems solved by technology

[0004] The above three planting methods in hilly areas all have deficiencies and defects, such as: rain-fed planting, which is a planting method of "relying on the sky", relying on climate and geographical conditions for planting. natural disasters and agricultural losses; in addition, because in the planting process of rain-fed planting, the period of rainfall cannot completely match the water demand time of the crop growth period, so it is impossible to meet the demand for supply and the quality of the planted crops Also general; due to the high climate requirements of this planting method, it cannot be carried out in semi-arid or arid areas

Human planting, the biggest obstacle lies in the high cost of management and labor; in the period of water shortage, people need to lift water from the lower part of the hilly area to the middle and upper part of the hilly area. The whole process is time-consuming, laborious and inefficient, and it is only suitable for some climatic conditions Better, lower-elevation plantations; moreover, this method is not suitable for large-scale cultivation

High-altitude irrigation is a very convenient and efficient irrigation method for large-scale planting, but the initial investment cost is huge, and the irrigation area of ​​unit-priced drones or small aircraft is also very limited, and the time and process of round-trip water replenishment are also very short. Time-consuming
