1results about How to "Improve starting efficiency" patented technology

The application provides a kind of adaptive soft start control method and system based on load prediction, before the start of belt conveyor, the initial load weight value on belt conveyor is obtained;Obtain the initial soft start parameter set corresponding to the load interval where the initial load weight value is located, the initial soft start parameter set includes start time, start curve slope and torque limit value;In response to the input of initial soft start parameter set, start the motor of belt conveyor;Within the first preset time period after the start of belt conveyor, real-time collection of actual load weight value and motor current value in operation;Based on the actual load weight value, obtain the fluctuation range of motor current value;Based on the relationship between the collected motor current value and the fluctuation range, correct the initial soft start parameter set;Real-time feedback of the corrected parameters to motor controller;The application effectively prevents belt slip, belt breakage and other faults, prolongs the service life of the equipment, improves the operation efficiency and safety of the whole conveying system.
