A frequency conversion system and control method for synchronous pumping irrigation

Abstract

The invention discloses a frequency conversion system for synchronous pumping irrigation and a control method. The frequency conversion system includes a water supply module for transporting irrigation water, a humidity detection module for detecting the humidity in a planting area, and a water supply module for controlling the operation of the water supply module. The frequency conversion control module of the state, the water supply module includes a water delivery pipe and a water supply pump, and the two ends of the water delivery pipe respectively extend to the water supply source and the planting area; the humidity detection module is arranged in the soil of the planting area; the frequency conversion The control module includes a frequency converter and a controller, and the controller records the normal water range required for plant growth; the humidity detection module, the frequency converter, the controller and the water supply pump form an electrical signal connection. The invention can automatically irrigate according to the actual conditions of the plants to meet the needs of the plants to the greatest extent, and can also control the amount of irrigation water in real time, and is suitable for different irrigation occasions.

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
