摘　　要：当前防坠制动状态监测过程较为被动,以事故发生后的传感信号识别为主,忽略了事故发生前制动绳的冲击力学特征,导致预判性差。为此,提出一种引入制动绳冲击力学特征的高空作业防坠器防坠制动状态监测与预警方法。针对防坠器制动绳冲击力学展开分析,将力学特征引入防坠制动过程中的相关条件,根据制动减速度、制动力、制动距离建立防坠制动状态阈值区间。利用不同传感器采集防坠制动过程的状态数据变化,将实际的防坠制动力与阈值区间作对比,判断是否需要发出预警。实验结果表明:该方法具有较高的状态监测精度与预警精度。In order to improve the poor prediction of monitoring anti-fall braking status due to the post-accident recognition of the sensing signal and ignore of the pre-war impact mechanical characteristics of brake rope,a method of monitoring and warning the fall arrest braking status of the fall arrest device for aerial work is proposed by introducing the impact mechanical characteristics of the brake rope.The impact mechanics of the brake rope of the fall arrester is analyzed,and the mechanical characteristics are introduced into the relevant conditions of the fall arrest braking process.According to the braking deceleration,braking force and braking distance,the threshold range of the fall arrest braking status is established.Different sensors are used to collect the state data changes during the anti-falling braking process,and the actual anti-falling braking force is compared with the threshold interval to determine whether an early warning is needed.The experimental results show that the proposed method has high precision of condition monitoring and early warning.
