Method and device for detecting full load of waste hopper

The invention discloses a waste hopper full load detection method and device, and relates to the technical field of steel cold rolling. The method comprises the steps that the first weight of waste steel loaded in a waste hopper is obtained; obtaining a preset weight threshold value; and if the first weight of the waste steel reaches the weight threshold value, it is judged that the waste hopper is fully loaded. The full-load state of the waste hopper can be accurately detected, waste steel is prevented from sliding off, and the yield can be increased. 本发明公开了废料斗满载检测方法及装置，涉及钢铁冷轧技术领域。所述方法包括：获取废料斗中装载的废钢的第一重量；获取预设的重量阈值；若废钢的第一重量达到重量阈值，则判断废料斗满载。本发明可准确检测到废料斗的满载状态，避免废钢滑落，有利于提高成材率。
