In recent years, elevators have come to be installed not only in general high-rise buildings but also in private houses. Most of these elevators are controlled by computers, from the control of the electric motor that drives the elevators to the sequential control of the elevators. The maintenance work is becoming more important in order to safely use these devices that have entered the home without failure.

The elevator is a vertical transportation system, and if a malfunction occurs once, the passenger can be confined in a limited space while driving, so that the passenger can be compared with the malfunctions of other vehicles. Will cause anxiety.
In addition, even if the passengers are not driving and the elevator stops, they have to walk up the stairs, which is a great obstacle to the traffic of the building. In particular, the movement of customers is restricted at department stores and the like, which will greatly affect sales.

Therefore, if a failure should occur, prompt recovery work is required. First of all, of course, it is necessary to rescue passengers, but it is required to immediately grasp the cause of the failure and repair the defective part.

The role of the computer is indispensable for this. The computer records the operating status of the elevator (including failure information, of course) and sends the selected information to the center. Based on this information, the center examines the cause of the failure before the maintenance personnel go to the failure site, and the maintenance personnel go to the site with this measure, so that the recovery work at the site is easier than when going straight. It will be possible in a short time.

However, when connected to the monitoring center, failure information can be obtained in advance, so local recovery will be faster than before, but it will take time to estimate the cause from the conditions and accuracy A large amount of data is needed to make a high estimate. This not only increases the size of the central center to which a large number of elevators are connected, but also allocates a lot of time to information transmission.
