Wireless interconnected control system and method used for electric driving reel spray irrigation machine and capable improving spray irrigation uniformity

Abstract

The invention discloses a wireless interconnected control system and method used for an electric driving reel spray irrigation machine and capable improving spray irrigation uniformity. The system includes a pressure PID controller composed of a microprocessor controller module, a wireless data transmission module, a single-chip microprocessor module and a frequency converter; a water pump motor;a pressure transmitter; a wireless transmission module; a cell phone APP client terminal; and an encoder. The pressure PID controller indirectly controls constancy of pressure of the inlet of a sprayhead through controlling the pressure change of inlet pressure of the reel spray irrigation machine. The microprocessor controller module, a brushless DC motor and a motor controller form a speed PIDcontroller controlling PE pipe recycling speed directly. The wireless transmission module realizes interactive communication of spray head inlet pressure and PE pipe recycling speed values with a client terminal in a short text message mode. Automatic adjustment of operation condition is realized after setting of corresponding parameters. According to the invention, spray irrigation uniformity ofthe reel spray irrigation machine is improved, and remote, real time and accurate control of operation condition of the reel spray irrigation machine is realized, so that foreground guarantee is provided for smart irrigation of the reel spray irrigation machine.

Description

Technical field [0001] The invention relates to the field of wireless control and motor control, in particular to a wireless interconnection control system and method for an electrically driven reel type sprinkler irrigation machine that improves the uniformity of sprinkler irrigation. Background technique [0002] Reel sprinkler irrigation machine is an important high-efficiency, water-saving irrigation equipment, and the sprinkler irrigation uniformity coefficient is one of the important indicators reflecting the quality of sprinkler irrigation. According to the requirements in GB 50085-2007 "Technical Specifications for Sprinkler Irrigation Engineering Part 4: Technical Parameters of Sprinkler Irrigation", the spray irrigation uniformity coefficient of the line sprinkler irrigation system should not be less than 0.85. [0003] The important factors that affect the uniformity of the reel sprinkler irrigation machine are the nozzle inlet pressure and the nozzle car recovery speed....
