On the basis of the above, it is known that it has reached the time when the elevator should be inspected, and the maintenance staff is dispatched to the building in which the elevator is installed to replace the replacement parts of the elevator equipment.

[0004]

However, although the disclosed means can know the operating time and the number of times of operation of the elevator car or the equipment for each elevator, simply by accumulating the measurement data, the inspection time of the elevator can be improved. Since it is only determined whether or not the measurement data has arrived, there is a problem that the measurement data obtained by the terminal device is not used more effectively and appropriately.

The present invention is intended to eliminate the above-mentioned problems, and its purpose is not only to determine whether the measurement data obtained by the terminal device is the time for maintenance and inspection of the elevator or the time for replacing the equipment for the elevator. , To provide an elevator operation data analysis device used for grasping the usage status unique to each elevator.

[0006]

To achieve the above object, the present invention provides a measurement for each elevator, which measures the frequency of use of the door, the door opening time, and the operating state of various switches for opening and closing each floor. Means, and a terminal device including storage means for storing the measurement data obtained by the measuring means, and a plurality of the terminal devices are connected via a communication line to process the measurement data obtained by each of the terminal devices. Consisting of a monitoring center, processing of the measurement data in the monitoring center, for each elevator, determine whether the measurement data for each floor is a predetermined value or more, for each elevator from the determination result, and, Be sure to understand the elevator-specific usage status for each floor, and at the same time,
Means for accumulating the measurement data for each floor to determine the next maintenance / inspection time of the elevator and the replacement time of the elevator equipment.

[0007]

According to the above means, the terminal device measures, for each elevator, the door opening / closing frequency for each floor, the door opening time, and various switches related to the door opening / closing, such as safety shoe switches. The measurement data obtained in step 1 is temporarily stored in the memory. Next, the monitoring center reads out the measurement data obtained by each terminal device and fetches the measurement data via the communication line. At the time of this fetching, the monitoring center executes the following two processes. To do.

The first is for each elevator, and
Among the measurement data obtained for each floor of the elevator, it is judged whether there is an abnormal value far from the standard value, and when an abnormal value is detected during this judgment, monitoring is performed. The center immediately gives an appropriate instruction to the elevator user who has shown the abnormal value, and secondly, at the same time as making the above determination,
The measurement data is aggregated for each elevator and each floor for a certain period of time, and it is possible to grasp whether or not each elevator is in a normal (standard) usage state based on the aggregated result. In consideration of the usage status of each elevator, the accumulated value of the measurement data until the maintenance and inspection timing of each elevator door and the replacement timing of the elevator equipment are obtained. And
The measurement data is accumulated for a relatively long period of time, and it is determined whether or not the accumulated value has reached the accumulated value indicating the inspection time and the replacement time.

As described above, according to the present invention, the obtained measurement data is used not only for determining the inspection time of the elevator doors and the arrival of the replacement time of the equipment for the elevators, but also the usage status peculiar to each elevator. Since it is used for grasping and instructing an elevator whose measurement data is abnormal, it is possible to use the measurement data more effectively and appropriately.
