Method for realizing automatic zoned constant pressure in field rotation irrigation by utilizing frequency converter

Abstract

The invention provides a method for realizing automatic zoned constant pressure in field rotation irrigation by utilizing a frequency converter, and belongs to the field of automatic control on large-scale irrigation. According to the method, on the basis of an existing variable-frequency speed-regulation constant-pressure irrigation system, the frequency converter is connected with a communication module by using a frequency converter serial port in a wired manner; the frequency converter is configured to be in a serial port communication state; the frequency converter is controlled by a communication interface; the communication module is connected with remote configuration software; and the configuration software reads pressure configuration information, and remote configuration is performed with the cooperation of the executing process of a rotation irrigation unit through the communication module to realize a dynamic change to keep pressure constant. The method solves the problemthat control over water supply pressure of large-area irrigation is not reasonable.

Description

technical field [0001] The invention relates to a method for automatic partition constant pressure of a field wheel irrigation frequency converter, which belongs to the technical field of large-scale irrigation automation control. Background technique [0002] In agricultural standardized production, farmland irrigation is one of the main links. Due to the lack of fixed irrigation facilities, the traditional irrigation method mainly relies on mobile water pumps for irrigation, which easily leads to soil erosion and soil compaction, and is limited by natural conditions such as the distance between the land and the river and the amount of water in the river during the irrigation season. Farmers can only use their own small water pumps or rely on manpower to irrigate the fields. The amount and speed of watering are all controlled by humans. The degree of automation is low, which directly affects the growth, quality and efficiency of agricultural products. [0003] With the dev...
