Title:
METHOD FOR MONITORING AND CONTROLLING SUPPORTING POSTURE OF SUPPORTING-TYPE HYDRAULIC SUPPORT ON BASIS OF DENSE POINT GROUP
Document Type and Number:
WIPO Patent Application WO/2023/087618
Kind Code:
A1
Abstract:
A method for monitoring and controlling a supporting posture of a supporting-type hydraulic support on the basis of a dense point group, which method relates to the technical field of intelligent mining devices. The method comprises: basic structure parameters being built in a control panel for a hydraulic support, and determining variable posture parameters during the operation process of the support; establishing a posture monitoring mathematical model for the support, and sequentially inputting stroke data of a front stand column and a rear stand column of the support into the model at an interval; on the basis of a dense point group interval definition, establishing, by using an N-X division method, a dense point group sample graph for posture monitoring of the hydraulic support; establishing a posture control mathematical model for the support, inputting, at equal intervals, full posture data of an elevation angle and a vertex angle within a rational supporting swing angle range of the support, and establishing a dense point group sample graph for posture control of the hydraulic support; and quickly searching, by using the N-X division method, for the current supporting posture of the support in the dense point group sample graph, and quickly searching, by using the N-X division method, for target lengths of the front and rear stand columns of the support in the dense point group sample graph. The efficiency and precision of monitoring and controlling a hydraulic support are thus improved.
