Title:
METHOD AND SYSTEM FOR QUANTITATIVELY PUSHING HYDRAULIC SUPPORT
Document Type and Number:
WIPO Patent Application WO/2024/036803
Kind Code:
A1
Abstract:
Provided are a method and system for quantitatively pushing a hydraulic support. The method comprises: step S101, acquiring a target pushing amount, controlling a binocular camera to capture an image, and calculating the initial distance between a scraper conveyor and the binocular camera using a binocular vision distance measurement algorithm; step S102, controlling the pushing of a hydraulic support according to the target pushing amount; step S103, calculating a distance after movement according to a re-captured image; step S104, calculating an actual pushing amount of the hydraulic support, determining whether the absolute value of the difference between the actual pushing amount and the target pushing amount is less than a preset error threshold, if so, completing the pushing, and if not, executing step S105; and step S105, updating the numerical values of the target pushing amount, the initial distance and the current distance, and returning to execute step S102.
