When thinking about elevator safety, specifically elevator inspection and maintenance operation, the monitoring and management of the wire rope condition - due to daily usage – is critical. Currently, elevator maintenance engineers develop a wire rope replacement plan by capturing the degraded condition of the wire rope based on results of visual checks and data collected (via use of a caliper) from measuring the rope diameter. However, market demand of high-speed elevators is increasing based on the growth of high rise buildings. In fact, just this year, a 600m (approx.) hoistway was measured and recorded – this is the highest to date. As a result of buildings climbing ever higher, extended elevator maintenance time has also increased and become a key challenge to overcome. Work hours have grown proportionally longer as hoistway heights rise. Unfortunately, longer hours can often lead to increased human fatigue and error during rope diameter measurement and maintenance. A more efficient and accurate process is needed. The development and implementation of a rope inspection device, using image processing, can mitigate existing challenges. This inspection device utilizes a high resolution line sensor camera with a high level image processor to more efficiently provide the rope diameter measurement data of the high speed moving ropes. This paper was created to report the general system configuration of the developed device, the image processing method and the results of verification tests.
