Synchronous pumping irrigation frequency conversion system and control method

Abstract

The invention discloses a synchronous pumping irrigation frequency conversion system and a control method. The frequency conversion system comprises a water supply module for delivering irrigation water, a humidity detection module for detecting humidity of a planting area, and a frequency conversion control module for controlling the working state of the water supply module. The water supply module comprises a water delivery pipe and a water supply pump, and two ends of the water delivery pipe respectively extend into a water supply source and the planting area. The humidity detection moduleis arranged in soil of the planting area. The frequency conversion control module comprises a frequency converter and a controller, and a normal moisture range required for plant growth is recorded inthe controller. The humidity detection module, the frequency converter, the controller and the water supply pump are in electrical signal connection. The synchronous pumping irrigation frequency conversion system and the control method have the advantages that irrigation can be performed automatically according to actual conditions of plants, needs of the plants can be met to the greatest extent,the amount of the irrigation water can be controlled in real time, and the system is suitable for different irrigation scenarios.

Description

technical field [0001] The invention relates to agricultural irrigation technology, in particular to a synchronous pumping irrigation frequency conversion system and a control method. Background technique [0002] In the existing agricultural irrigation, the way of transporting water and the way of supplying water are in a relatively backward state. In many places, manual transportation and management of water resources are required to a large extent, and it is difficult to fully realize and popularize automation. Moreover, my country's water use has peak and trough periods in terms of region and time. In the use of electric energy, peak and trough periods will be adjusted and frequency adjusted. deployment. [0003] Generally, the commonly used water supply method in existing irrigation is: use the irrigation water supply method combining the water pump and the reservoir, store water first, and then irrigate; in this water supply method, first pump water from the water sour...

AI Technical Summary

Problems solved by technology

In the above-mentioned water supply methods, it is necessary to build a reservoir and install multiple water pumps, which will not only increase the hardware cost of irrigation, but also occupy a large area of ​​land, and the water pressure of irrigation cannot be adjusted according to the actual situation at any time, let alone take into account different occasions different needs of
