System of Magnetic-Pulse Unit Parameters Automated Control for Plant Treatment in Gardening

Lately, big attention is paid to environmentally friendly production in agriculture. One of the alternatives to the use of genetically modified organisms or production chemicals is influence on biological objects by electrophysical methods. The article presents the 3D model of the computer-aided design system "KOMPAS-3D" of an automated unit for magnetic-pulse treatment of plants.Its use will improve the productivity and environmental safety of horticultural crops at different technologies of production. Electronically controlled electrocylinders (actuators) for driving of the working tools (inductors) were sorted out. Actuators were designed for automatic adjustment of the working tools of the unit for agrotechnological parameters of plants, shafts lifting/lowering and extension in a vertical plane and inductors tilt angles up to 90 in the horizontal plane. Electrocylinders have a significant advantage in automatic control to other types of hinged lifting devices due to a high accuracy rate of movement and operation flexibility. The actuators with 12 V supply, 50 W power, the 200-600 mm operating rod stroke, 10-45 mm/s speed, 200-900 H load were sorted out through the study. These electrocylinders provide a change of operating width to 3.6 m, 300 mm lifting/lowering of the working elements with a weight of 50 N, changing the tilt angle of the inductors in the horizontal plane up to 75 degrees. As a result the process of plants irradiation can be automated. The principle of operation of the mobile unit for magnetic-pulse treatment of plants, the scheme of the automated system changing the operating width, maintenance the specified distances between and tilt angle between inductors and plants treated by the low-frequency magnetic field are presented. A flowchart describing the system operation algorithm and a program code of calculating the required displacement of the actuator rod in a Sublime Text were worked out. After setting the desired value of the distance to the object exposure a cycle is started. The cycle includes determining the current distance to the object, calculate the change of this parameter and stock moving to the required distance.
