The invention concerns a method, system and computer program for monitoring the run of a roping interconnecting a car and a counterweight of an elevator and for detecting an abnormal operation condition during the drive of a traction sheave intending therewith the car and the counterweight to be moved via the roping. the roping is running on its way from the car to the traction sheave via at least one pulley and on its way from the counterweight to the traction sheave via at least one pulley, wherein the rotation of the at least two pulleys is monitored by sensing their rotation. These rotation data are then analyzed in view of a mutual correlation indicating therewith a synchronized run of the roping on either side of the traction sheave, and detecting therewith an abnormal situation when detecting an absence of such correlation.

    本发明涉及一种方法、系统和计算机程序,该方法、系统和计算机程序用于监控使轿厢和电梯的配重互连的绳索的运行,并在意在与轿厢和配重通过所述绳索一起移动的曳引绳轮的驱动期间检测异常操作状况。所述绳索在其经由至少一个滑轮从轿厢到曳引绳轮的路程中和其经由至少一个滑轮从配重到曳引绳轮的路程中行进,其中所述至少两个滑轮的旋转通过感测它们的旋转来监控。然后,根据相互相关性对这些旋转数据进行分析,该相互相关性指示曳引绳轮的任一侧上的绳索同步运行,并且在检测到不存在这种相关性时随之检测异常情况。
