摘要

在世界各地,现代电梯每天安全舒适地运送数百万乘客和货物。自从19世纪初出现现代电梯以来,这一交通系统取得了一些进步。其中,安全条件明显改善。因此,现代电梯必须配备安全保护系统,以确保安全条件,避免事故发生。超速调节器是这种安全系统的组成部分之一。当电梯轿厢达到过快速度时,它起到了停止机构的作用,即跳闸速度。当达到跳闸速度时,超速调节器被机械锁定并停止绳索,从而停止电梯轿厢。本文介绍了一种新的测量系统的开发,该系统能够借助移动电子设备(智能手机或平板电脑)上的图形界面来测量超速调速器的触发速度。实际应用:一种新型调速器测速系统采用移动电子设备进行非接触式测速。这种新工艺可以取代维修技术人员目前使用的不准确的测量系统,从而提高其可靠性。主要目标包括严格测试超速调速器的操作。所开发的系统保证在几种异常操作情况下自动执行测试,从而允许用户实时访问通过移动电子设备上可用的图形界面获得的测试数据。

Automatic velocity measurement system applied to elevator overspeed governors
All around the world, modern elevators transport safely and comfortably millions of passengers and freight each day. Since modern elevators emerged at the beginning of the 19th century, several advances have risen in this transportation system. Among them, safety conditions were significantly improved. Therefore, modern elevators must be equipped with safety protection systems to assure safety conditions and avoid accidents. An overspeed governor is one of the components of such a safety system. It acts as a stopping mechanism when the elevator car reaches an excessive velocity, known as tripping speed. When the tripping speed is reached, the overspeed governor is mechanically locked and halts the rope, thus stopping the elevator car. This paper describes the development of a new measuring system able to measure the trigger velocity of an overspeed governor with the help of a graphical interface available on a mobile electronic device (smartphone or tablet). Practical application: A new overspeed governor velocity measuring system uses a mobile electronic device for non-contact velocity measurement. This new process may replace the inaccurate measuring system currently employed by maintenance technicians, thus increasing its reliability. The main objective consists of rigorously testing the operation of overspeed governors. The developed system guarantees the automatic execution of the test under several anomalous operating situations, thus allowing the user to have real-time access to the test data obtained through a graphical interface available on a mobile electronic device.
