Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator remote maintenance method and a remote maintenance system.

[0002]

2. Description of the Related Art An elevator vibration analyzing apparatus detects an elevator running vibration, analyzes the detected data, and outputs an elevator function or a failure location. Used for failure repair.

With reference to FIG. 7, a conventional vibration analyzing apparatus using a sensor and a measuring device will be described. A counter rope 3 and a cab 5 are attached to both ends of a main rope 4 wound around a hoist 1 and a warp wheel 2. A measuring instrument 6 is installed in the cab 5, and the measuring instrument 6 is connected to an acceleration sensor 7 mounted below the floor of the cab 5.

[0004] A conventional elevator vibration analyzing apparatus is composed of a measuring instrument 6 and an acceleration sensor 7.
The vibration during the traveling of the elevator detected in the above, ie, the analog data of the traveling vibration is supplied to the measuring device 6, where the traveling vibration is analyzed.

[0005] The traveling vibration of an elevator has a complicated form in which the vibration generated from the control system of the elevator and the vibration generated from each component device constituting the elevator are superimposed. It is also necessary to consider unsteady vibration due to a transient change due to acceleration or deceleration in an elevator having a short moving distance.

[0006] Therefore, in order to determine the cause of a failure location of an elevator, to detect the failure location, and to grasp the state, a correlation between a physical state quantity such as the position and speed of the elevator and the frequency spectrum of the acceleration signal of the elevator. It is considered that the analysis is performed.

Conventionally, an analysis method using Fourier transform or wavelet transform has been known for analyzing the running vibration of an elevator. However, the operation of measuring instrument 6 for analysis and the operation of reading the analysis result are complicated. It is.

In addition, in the conventional elevator vibration analyzer, an operator operates the measuring instrument 6 to measure the running function of the elevator and to analyze the measured data. Abundant experience and a high level of knowledge are required to make judgments on abnormal locations.

On the other hand, a vibration analyzer as shown in FIG. 8 is also known as an improved type. That is, vibrations during the traveling of the elevator detected by the acceleration sensor 7 installed under the floor of the cab 5 are supplied to the elevator control panel 9 as analog signals via the tail cord 8. In the control panel 9, the analog signal is converted into a digital signal by a built-in analog / digital converter and stored in the control panel 9. Then, the personal computer 11 takes in acceleration data from the control panel 9 via the telephone line 10, and performs data analysis here.

In the case of this apparatus, since data is taken into the personal computer 11 through the telephone line 10, it is possible to analyze the data even if a technician is not in the elevator installation building, for example, from a remote place such as a service center. it can.

However, since a plurality of factors are superimposed on the traveling vibration of the elevator as described above, it is not easy to identify the cause of the abnormality only by analyzing the acceleration signal. Although data analysis can be performed at a service center or the like, a maintenance technician must travel to the site each time the acceleration sensor is attached to the inspection target elevator.

[0012]

As described above, FIG.
In the elevator maintenance method using the conventional elevator vibration analysis device shown in (1), a maintenance technician having advanced experience and knowledge needs to read and analyze the traveling vibration data of the elevator. It took considerable time. In a maintenance method using a conventional elevator vibration analysis apparatus shown in FIG. 8 in which this is improved, measured acceleration data is taken into a personal computer via a telephone line, and data analysis is performed in the personal computer. The analysis also took a considerable amount of time, and it was necessary to attach an acceleration sensor to the elevator car each time the inspection was performed.

Therefore, according to the conventional elevator maintenance method using the vibration analysis apparatus, not only when a sudden failure of the elevator occurs, but also when performing periodic elevator adjustment and maintenance inspection, the vibration analysis is performed. It takes a lot of time to understand the cause of the problem and respond to it,
The improvement was requested.

Further, with these methods for estimating the cause of the abnormality only from the analysis of the acceleration data in the cab, it is not easy to distinguish the abnormality in the cab or the car frame from the abnormality in the rail side, and the repair work is difficult. There is a problem that the effect of reducing the vibration after performing the above cannot be evaluated in advance.

The present invention has been made to solve such a conventional technical problem, and it is relatively easy to analyze the traveling vibration of an elevator, find an abnormal location, and deal with a repair work corresponding thereto. It is an object of the present invention to provide a remote maintenance method and a remote maintenance system for an elevator, which can be performed accurately and accurately, can respond quickly when a problem occurs, and can improve the operation efficiency of the elevator.
