[Conventional technology]

Conventionally, the inspection of the elevator has been performed by a maintenance staff who regularly visits and confirms the operating state of each part of the elevator visually or using a measuring instrument.

However, in this conventional inspection method, the diagnosis of the operating state of each part of the elevator may be different due to the difference in the measurement technique of the maintenance personnel and the judgment based on the experience, and there is a drawback that the inspection result shows individual differences. .

For this reason, the parts replacement and maintenance work performed based on the above-mentioned inspection results are unnecessary but unnecessary,
On the contrary, because it was left without replacing parts or performing maintenance work,
Occasionally, a failure accident occurred in the elevator.

Therefore, Japanese Patent Laid-Open No. 60-244782 proposes an elevator inspection system that efficiently performs inspection with high diagnostic accuracy in accordance with the operating environment of the elevator, the operation history, and the characteristics of each device.

And is output to the display device or the printing device of the mobile terminal 5 as needed.

In this way, according to the above-mentioned method, the inspection data focusing on the main points according to the judgment of the maintenance personnel and the extracted data of the abnormal portion before the failure are written in the RAM of the mobile terminal 5 and are stored in the monitoring center. After taking it back, the host computer 7 analyzes time series changes for each elevator.

Then, based on the result of this analysis, the timing of parts replacement, adjustment, etc. for each elevator is efficiently determined with high diagnostic accuracy.
