FIG. 3 is a block diagram of a configuration according to an embodiment of the present invention.
4 is a graph showing analytical data according to an embodiment of the present invention.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

2 to 4 show a preferred embodiment of the present invention. 2, the present invention is characterized in that when the elevating car 11 of the elevator 10 is lifted and lowered by the hoisting ropes 13, the vibration on the elevating car 11 is measured, It is a system for analyzing and analyzing this, so as to anticipate the failure of the parts of the device and at the same time to take appropriate follow-up measures quickly.

The vibration system 30 is installed at the upper end of the elevator car 11 of the elevator 10 so as to measure the vibration of the elevator car 11. The elevator car 11 is stably lifted and lowered in a state of being suspended from the hoist rope 13 It is possible to predict the malfunction or the wear state of the drive motor 15, the rope pulley 17, or the guide roller 18 of the hoisting means 13 in accordance with the change of the vibration.

Specifically, the vibrometer 30 is displayed by a controller 31, which will be described later, so that it can be visually analyzed while transferred to a display device 40 carried by a manager or installed in a control room or the like. The following is an explanation.

3, the present invention includes a vibration system 30 that is installed directly on an elevator car 11 of an elevator 10 to measure vibrations generated during operation of the elevator 10, The controller 31 can be provided in a single module form.

To this end, the controller 31 is provided with a case 32 mounted on the upper end of the elevator car 11. The vibration system 30 is installed in one side of the case 32, A control unit 33 connected to detect a frequency and a communication module 34 transmitting a frequency detected by the control unit 33 may be provided.
