Example Embodiment

[0020] in figure 1 Among them, the automatic control device for constant pressure water supply of the solar-based micro-irrigation system includes solar panels, charge and discharge management, storage batteries, solar radiation intensity detection, power circuits, automatic water-lifting control systems, water pumps, wireless communication modules, reservoirs, and water levels Detection, low-power solar panels. The device uses solar power to drive a low-power DC water pump to lift the water into a reservoir built at a high place, and use the water in the reservoir as a head for gravity drip irrigation, while controlling the water level of the reservoir Maintain a constant value to achieve constant pressure water supply. In the drip irrigation process, the water level of the reservoir is detected in real time, and when the water level is lower than a certain set value, the water pump is controlled to lift water. In practical applications, there is a certain distance between th...

Abstract

The invention discloses a solar-based constant-pressure water supply automatic control device for a micro irrigation system. The device comprises a solar cell panel, charging and discharging management unit, a storage battery, a solar radiation intensity detection unit, a power supply circuit, an automatic water lifting control system, a water pump, a wireless communication module, a water storagepond, a water level detection unit and a small-power solar cell panel. A liquid level sensor YZ-YO-LAG1 is used to online detect the water level of the water storage pond which is built at a high position, and DP-60 is controlled according to the water level information to lift water into the water storage pond, and enable the water level of the water storage pond to be kept at a certain fixed height in the drip irrigation process to realize constant-pressure water supply. The water level detection information of the water storage pond and the start and stop of the DP-60 are transmitted and controlled wirelessly by the wireless communication module CC1100.

Description

Technical field [0001] The invention relates to an automatic control device for water supply, in particular to an automatic control device for constant pressure water supply of a micro-irrigation system based on solar energy. Background technique [0002] Micro-irrigation has the characteristics of water and fertilizer saving, labor saving, energy saving, and strong adaptability to soil and terrain. Micro-irrigation systems are increasingly widely used in the development of facility agriculture, water-saving agriculture, and ecological construction. , High-quality important technical means. In the process of micro-irrigation, the stability of water pressure or water flow in the pipeline has a significant impact on the uniformity of irrigation, especially on the fertilization performance of automatic fertilization devices such as Venturi fertilization devices and hydraulic drive fertilization devices. [0003] At present, some small and medium-sized orchards, greenhouses, nu...
