Water taking and pressurizing control system of solar sprinkler

Abstract

The invention discloses a water taking and pressurizing control system of a solar sprinkler. The system comprises a solar photovoltaic power generating module, a direct-current brushless motor control circuit and a water source constant water level automatic water replenishing control circuit. The solar photovoltaic power generating module respectively powers the direct-current brushless motor control circuit and the water source constant water level automatic water replenishing control circuit. The direct-current brushless motor control circuit controls the power supply of a water pump. The control system has the advantages that the system uses clean solar energy to supply power, wireless control is used, convenient operation is achieved, remote on and off control of units is achieved, remote transmission indication and alarming of a system fault state unit can be achieved, a high-performance brushless direct-current motor is used to drive a self-priming pump, high system reliability and low energy loss are achieved, the water pump is started in a convenient and labor saving manner, automatic irrigation can be achieved conveniently, universality and flexibility of sprinkling irrigation units are increased effectively, and the irrigation requirements of farms, pastures, crops, economical crops and forage grass are satisfied.

Description

technical field [0001] The invention relates to a water intake pressurization control system for a sprinkler irrigation machine, in particular to a control circuit for a DC brushless pump pressurization system of a solar sprinkler irrigation machine. Background technique [0002] There are two important factors restricting the further expansion of the irrigated area, one is the restriction of water resources; the other is the lack of power supply in the irrigated area. However, these areas are rich in solar energy resources. Using these abundant solar energy natural resources, combining photovoltaic technology with modern advanced irrigation technology, using limited water resources to develop photovoltaic irrigation technology, and promoting food production and ecological improvement, is my country's economy, An important path for social and ecological sustainable development. As one of the water-saving irrigation measures, sprinkler irrigation plays an important role in a...
