电梯制动器失效边缘检测方法及系统

本发明公开了一种电梯制动器失效边缘检测方法及系统,属于电梯制动性能检测技术领域。首先定义轿厢空载以最大允许速度上行至上端强制减速位置、以及装载110%额定载重以最大允许速度下行至下端强制减速位置为制动器失效边缘条件;根据最大运行速度及缓冲器参数计算理论最小制停减速度;采用同载二次制动法,在空载上行中部与上部、110%载下行中部与下部四个工况下测量实际制动减速度,引入钢丝绳弹性修正、补偿链非均匀修正、温湿度补偿及转动惯量解耦等多物理场补偿模型,利用差分公式计算失效边缘的实际制停减速度;计算安全裕度系数进行三级分级预警。具有检测精度高、安全性好和自动化程度高、能够检测电梯制动器失效边缘并预测剩余寿命。
