Abstract

The invention discloses a photovoltaic lift irrigation control system capable of achieving automatic frequency adjustment, and the system comprises an MCU control circuit, a solar charging circuit, a voltage-stabilizing module, an electric quantity detection module, a wireless module, a key control panel, a valve drive circuit, a valve state feedback circuit, and a frequency converter. According to the technical scheme of the invention, the system brings convenience for the control management of valves and a lift irrigation water pump set in the system, can control the opening and closing of valves in two modes of wireless remote control and control panel operation, can correspondingly carry out the variable frequency control of the working state of the lift irrigation water pump set according to the water level of a pool, and meets different operation demands. Meanwhile, the working states of the valves are inputted into an MCU after optoelectronic isolation, and are timely fed back to a control terminal. The system can monitor the states of all valves in real time, can obtain the related onsite conditions under the condition that no person needs to go to a site, improves the overall automatic level of a lift irrigation station, greatly reduces the labor intensity of a worker, and reduces the manual cost.

Description

technical field [0001] The invention relates to the technical field of photovoltaic lifting irrigation control, in particular to a photovoltaic lifting irrigation control system that realizes automatic frequency adjustment. Background technique [0002] With the continuous advancement of science and technology, intelligent lifting irrigation technology is more and more widely used in modern agriculture. Solenoid valve is the most widely used actuator in agricultural intelligent lifting irrigation system. How to quickly, stably and conveniently control the solenoid valve in the lifting irrigation plays an important role in the stability of the intelligent lifting irrigation system of the entire farmland. Especially in some remote areas with large farmland areas, there are many valves in the lifting irrigation system, and manual switching of the valves is labor-intensive, and the working status of the lifting irrigation pump unit cannot be flexibly and automatically adjusted ...
