Embodiment Construction

[0027] Embodiments of the present invention provide capabilities for obtaining information about the performance or condition of a portion of an elevator system based on vibration indications corresponding to operation of an elevator machine.

[0028] figure 1 Selected portions of the example elevator system 20 are schematically illustrated. Elevator machine 22 is configured to selectively control movement of elevator car 24 and counterweight 26 in a generally known manner. Such as figure 2 As shown in , elevator machine 22 includes motor 30 , brake 32 and traction sheave 34 . The machine also contains bearings which are not visible in the illustration. Machine 22 is mounted within elevator system 20 using support frame 36 .

[0029] At least one vibration sensor 38 is located proximate to machine 22 for detecting vibrations associated with operation of machine 22 . For illustrative purposes, the figure 2 Two vibration sensors 38 are shown in . in phantom figure 2 O...

Abstract

An illustrative example embodiment of an elevator system includes a machine including a motor and a brake. The machine is configured to selectively cause movement of an elevator car. At least one vibration sensor situated near the machine provides an indication of operation of the machine to indicate at least stops and starts of the machine associated with stopping and starting movement of the elevator car.

Description

Background technique [0001] Elevator systems are useful for carrying passengers and items between different floors in a building. Although elevator systems are reliable, they tend to require maintenance or repair as system components age or fail. Over time, various solutions to such problems have been developed. While there is a desire to obtain better performance data for monitoring elevator systems, currently no solution exists for providing such data at a reasonable cost. Contents of the invention [0002] An illustrative example embodiment of an elevator system includes a machine including a motor and a brake. The machine is configured to selectively cause movement of the elevator car. At least one vibration sensor located in the vicinity of the machine provides an indication of operation of the machine for at least the motion associated with stopping and starting movement of the elevator car. Stop and start of the machine. [0003] An example embodiment incorporati...
