The invention discloses a wireless interconnection control system and method for an electric-driven reel type sprinkler irrigation machine that improves the uniformity of sprinkler irrigation. The system includes a pressure PID controller composed of a micro-processing controller module, a wireless data transmission module, a single-chip microcomputer module, and a frequency converter. And water pump motor, pressure transmitter, wireless transmission module, mobile phone APP client, encoder, pressure PID controller indirectly controls the constant nozzle inlet pressure by controlling the pressure change of the reel sprinkler irrigation machine inlet pressure, and the microprocessor controller The module is composed of a brushless DC motor and a motor controller. The speed PID controller directly controls the recovery speed of the PE pipe. The wireless transmission module communicates the inlet pressure of the nozzle and the recovery speed of the PE pipe with the client through SMS mode. After setting the corresponding parameters Automatic adjustment of working conditions is realized, and the invention improves the uniformity of the sprinkling operation of the reel sprinkler irrigation machine, realizes remote real-time and precise control of the working conditions of the reel sprinkler irrigation machine, and provides a front-end guarantee for the intelligent irrigation of the sprinkler irrigation machine.
