摘要: 针对现有液压支架监测系统未实现液压支架综合工况全面监测和评价的问题，建立了液压支架综合工况评价模型。通过安装于支架顶梁、前连杆、底座上的姿态传感器得到顶梁与水平面夹角、前连杆与水平面夹角、底座与水平面夹角，结合评价模型计算采高、立柱总长度、平衡油缸总长度，综合分析液压支架姿态和受力状态，实现对支架支护工况的综合评价。Abstract: In view of problem that existing hydraulic support monitoring system had not realized comprehensive monitoring and evaluation of conditions of hydraulic support, evaluation model of comprehensive condition for hydraulic support was established.Through attitude sensors installed on top beam, front connecting rod and base of the support, angles between top beam and horizontal plane, front connecting rod and horizontal plane, base and horizontal plane were collected. Mining height, total length of column, total length of balance cylinder was calculated according to the evaluation model. Comprehensive evaluation of support conditions was achieved by analysis of attitude and force state of hydraulic support.
