Abstract

PURPOSE:To make maintenance of elevator without giving inconvenience to users by connecting a central monitor station with an elevator monitor board as terminal unit through a communication circuit, and allowing the central station to devise the maintenance schedule for each place an elevator is installed on the basis of the operating frequency of the elevator. CONSTITUTION:A central monitor station 1 is connected with an elevator monitor board 2... in each place where an elevator is installed as terminal unit through a public communication circuit 3, and these monitor boards 2 are connected with respective elevator control devices 4. From the applicable control device 4, each monitor hoard 2 receives the operating frequency showing the operating condition of the elevator at certain intervals and transmits as data to the central monitor station 1 via the communication circuit 3. The station 1 classifies the received data using a memory device by places of elevator installation, stores in memory at any appropriate time, compares the data for each elevator in a certain period with the address data for the applicable place of elevator installation, and decides the maintenance schedule of the elevator on the basis of the time zone in which the operating frequency is minimized.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to elevator remote maintenance systems.

[0002]

2. Description of the Related Art Conventionally, a maintenance person (maintenance company) who is in charge of elevator maintenance within a certain area decides the maintenance work of the elevator according to a uniformly decided schedule regardless of the operating status of each elevator. I was going to the day and time.

[0003]

In the conventional method like this, the operation is stopped due to the elevator inspection work and the many users are annoyed even though there are many users.

Therefore, the operation state of the elevator may be investigated to know at what date and time it should be inspected, but such an investigation requires special equipment and skilled technology, and it is quite easy to find one elevator. It was also difficult to grasp the operating status of one vehicle. Furthermore, it took a lot of time to analyze the survey results.

Therefore, the present invention utilizes an elevator remote maintenance system to allow a central monitoring station to grasp all operating states of a plurality of elevators at each elevator installation under its control, and thereby to optimize the overall operation. By deciding the maintenance work implementation plan (date and time), the purpose is to make the maintenance work as trouble-free as possible.

[0006]

[Means for Solving the Problems] A central monitoring station is equipped with a storage device for storing information on the number of times each elevator is operated from an elevator monitoring panel at an elevator installation site and a storage device for each elevator installation location (address). A comparison device for comparing two data is provided.

[0007]

With such a configuration, the central monitoring station grasps the number of times the elevator operates each hour from each elevator monitoring panel of the terminal, identifies the time zone in which the number of times of operation is low, and
Determine the maintenance plan for each elevator site, taking into account the time zones of the elevator sites.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on the embodiments shown in FIGS.

A public communication line 3 connects a central monitoring station 1 and an elevator monitoring panel 2 at an elevator installation site of a terminal. Further, the elevator monitoring board 2 is connected to the elevator control device 4.

The elevator monitoring board 2 receives the number of times of operation indicating the operating state of the elevator from the elevator control device 4 at predetermined intervals and transmits it to the monitoring station 1 as data via a line.

In the monitoring station 1, the received data is classified by the storage device 5 for each elevator installation site, and then stored in the storage device 5 at an arbitrary time, and the data and address of each elevator for the same fixed period are stored. The comparison device 7 compares the address data of each elevator installation stored in the storage device 6 to identify the maintenance time of each elevator. As a result, the number of times the elevator is used is minimized, and time zones that do not overlap between elevator installations within a predetermined range are extracted, and the maintenance date and time for that area is determined in consideration of the relationship with other areas. The printer 8 prints out as a maintenance schedule.

When the maintenance schedule is determined as described above, it is possible to specify a time zone in which a plurality of elevators of a plurality of elevators within a certain range are rarely used so as not to overlap as a maintenance time, and the maintenance work is performed in that time zone. As a result, it is possible to prevent the user from being inconvenienced, and the maintenance service is improved.

[0013]

EFFECTS OF THE INVENTION According to the present invention, the maintenance work time, which has been conventionally determined irrespective of the use situation of the elevator, can be selected so as not to disturb the user as much as possible, and the maintenance work in the area can be made efficient Since this can be done, it also saves labor in maintenance and improves maintenance service.
