Title:
METHOD FOR MONITORING AND CONTROLLING SUPPORTING POSTURE OF SUPPORTING-TYPE HYDRAULIC SUPPORT
Document Type and Number:
WIPO Patent Application WO/2023/087619
Kind Code:
A1
Abstract:
A method for monitoring and controlling the supporting posture of a supporting-type hydraulic support, which method relates to the technical field of intelligent mining devices. The method for monitoring and controlling the supporting posture of a supporting-type hydraulic support comprises: a support posture monitoring process, which involves: reading length (L8, L7) parameters of stand columns using stand column liquid level sensors (8) of a hydraulic support, establishing a posture monitoring mathematical model, and solving same by means of an interpolation algorithm, so as to acquire posture parameters comprising associated posture parameters such as an elevation angle (J1), a vertex angle (J7), and inclination angles (J8, J9) of the stand columns; and a support posture control process, which involves: according to the current supporting posture obtained in the monitoring process, first acquiring a contour line (11) of a top plate above the support by means of an area array laser sensor (10) and determining a protruding edge of the top plate, so as to obtain the elevation difference (ΔH) between a top beam (5) of the support and the top plate, calculating a target elevation (H') and a target vertex angle (J7') of the hydraulic support, calculating a target elevation angle (J1') of the support using a posture control mathematical model, substituting a target parameter into the posture monitoring mathematical model, obtaining, by means of calculation, target lengths (L7', L8') of the stand columns, and controlling the supporting posture. Full-time monitoring and control over an action posture of a hydraulic support can thus be realized.
