STRUCTURAL HEALTH MONITORING OF AN ESCALATOR DRIVE SYSTEM

A structural health monitoring system is provided. The system includes a drive system having a first drive member 32, a second drive member 38 operationally connected to the first drive member, and a tension member 39 operationally connecting the first drive member to the second drive member. At least one sensor 50 is configured to monitor a characteristic of at least one of the first drive member and the second drive member. A processor 54, in communication with the at least one sensor, is configured to determine if the structural health of the tension member is compromised based on the monitored characteristic. The processor is further configured to perform a safety response action when the structural health of the tension member is determined to be compromised. 提供种结构健康监测系统。所述系统包括具有第驱动构件32、操作性地连接到所述第驱动构件的第二驱动构件38以及将所述第驱动构件操作性地连接到所述第二驱动构件的受拉构件39的驱动系统。至少个传感器50被配置来监测所述第驱动构件和所述第二驱动构件中的至少个的特性。与所述至少个传感器通信的处理器54被配置来基于所述监测的特性确定所述受拉构件的结构健康是否受到损害。所述处理器被进步配置来在所述受拉构件的所述结构健康被确定受到损害时执行安全响应动作。
