The present invention provides a wireless interconnection control system for improving sprinkler irrigation uniformity of hose reel irrigator with electric drive comprising a micro processing controller module, a frequency converter, a water pump AC motor, a pressure transmitter, a GPRS wireless transmission module, a mobile phone client APP, and a coding speed detection module. The microprocessor controller module and the frequency converter form a pressure PID controller to indirectly control the constant nozzle inlet pressure by controlling the pressure of the incoming pressure of the hose reel irrigator. The microprocessor controller module and the matching motor controller with brushless DC motor form a speed PID controller to directly control the reel back speed of the PE pipe. The GPRS wireless transmission module interactively communicates the nozzle inlet pressure, the reel back speed of the PE pipe and the mobile phone client APP through the short message mode. After setting the corresponding parameters, the system realizes the automatic adjustment of the working conditions, improves the uniformity of the sprinkler irrigation operation of the hose reel irrigator, and realizes the remote real-time and precise monitoring of the working conditions of the hose reel irrigator, which provides a front-end guarantee for the intelligent irrigation of the irrigator.

Wireless interconnection control system and method for improving sprinkler irrigation uniformity of hose reel irrigator with electric drive

A sprinkler cart of hose reel irrigator in folding truss inhaul-cable type includes a cart body, a water supply pipeline, a folding truss structure and an inhaul-cable structure. The folding truss structure adopts a planar multi-rod folding structure, drives a three-rod folding through a single hydraulic cylinder, and is mounted on the cart body in combination with the inhaul-cable structure.
