Control method, device and system for sucking single steel plate based on current regulation, magnetism regulation and sub-control

Abstract

The invention discloses a control method for sucking a single steel plate based on current regulation, magnetic regulation and sub-control. The control method comprises the following steps: acquiring specification information of the steel plate; based on the specification information of the steel plate and a calculation formula, converting the current value into a current value for absorbing a single steel plate; based on the magnetic coupling coefficient k, an accurate current value for sucking a single steel plate is obtained; based on the length and the placing position of the steel plate, the sub-control combination form of the electromagnet is determined; based on the voltage required for achieving the accurate current value for attracting a single steel plate, the electromagnetic induction principle is adopted, an electromagnet coil is controlled to generate magnetism through current flowing, and the steel plate is attracted. Intelligent and unmanned steel plate storehouses are achieved, intelligent upgrading of crane electromagnet automatic control needs to meet the requirements for automatic adjustment of magnetic force intensity and electromagnet sub-control selection according to steel plates of different specifications, then the precise separation function is met, and the beneficial effects of being constant in magnetic force, precise in sub-control and the like are achieved.
