BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data management system for equipment that centrally collects and manages operational data of equipment installed in a building.

0002

[Background Art] Equipment such as elevators and passenger conveyors installed in buildings are maintained in a safe operating state by regularly performing maintenance and inspection work at intervals of a predetermined cumulative operating time. is necessary. Therefore, in order to know when to perform maintenance and inspection work, terminal devices have been placed in buildings that capture and store operating data from equipment installed in the building. This terminal device includes measuring devices such as a frequency meter that counts the number of times each equipment is activated and a cumulative hour meter that counts operating hours, and a device that detects when the data of these measuring devices reaches a preset value. There are detectors and alarms installed. Further, the terminal device is connected via a communication line to a monitoring center provided at a remote location that centrally monitors a plurality of terminal devices.

[0003] When the data from these measuring instruments reaches a preset limit value, the detector detects this and issues a detection signal that activates the alarm, which sends maintenance information to the monitoring center via the communication line. A request signal is sent. When this maintenance request signal is received by the monitoring center, a maintenance inspection worker is dispatched from the monitoring center to the required building. They were conducting maintenance and inspection work such as inspections.

0004

[Problems to be Solved by the Invention] In the conventional method described above, when a request for maintenance and inspection work is generated, a maintenance request signal is sent from the terminal device to the monitoring center. It is not possible to grasp the schedule and schedule maintenance and inspection work. For this reason, the monitoring center must always have a number of maintenance and inspection workers on standby at all times, the number of which is expected to be necessary based on the track record of conventional maintenance and inspection work. Furthermore, as equipment gets older, it is naturally necessary to change the limit values that form the basis of the maintenance inspection requests, but conventionally, maintenance inspection workers go to the site and change the limit values for each piece of equipment. It was necessary to carry out complicated work over a considerable period of time.

The present invention was made in view of the current state of operation data management as described above, and its purpose is to manage the operation data of equipment and change the limit value of the operation data for determining maintenance inspection requests. It is an object of the present invention to provide a data management device for equipment that can be easily performed.

[0006]

[Means for Solving the Problems] The object is to provide a terminal device that is connected to a plurality of terminal devices via a communication line, and that is connected to a plurality of terminal devices via a communication line. A data management device for equipment comprising a monitoring center that centrally manages operating data of equipment, including a setting means for setting a limit value for the operating data, and a setting means for setting a limit value for the operating data; This is achieved by adopting a configuration in which the monitoring center is provided with a collection means for acquiring the data via a communication line, and a comparison means for comparing the operational data acquired by the collection means with the limit value.

[0007]

[Operation] With this configuration, the operating data of the equipment written in the storage means of the terminal device is retrieved and retrieved by the collection means of the monitoring center via the communication line. The need for maintenance and inspection work is determined on the monitoring center side by comparing the obtained operating data with the set value set in advance by the setting means by the comparison means. In this way, the monitoring center performs maintenance and inspection work based on the necessity of maintenance and inspection work for equipment obtained from each terminal device. Furthermore, when the equipment becomes old and the setting values need to be changed, the changes are made by the setting means on the monitoring center side.

When the elevator is operated in this manner, the frequency meter 14 counts the number of times the up-operation relay contact 12 and the down-operation relay contact 13 are closed, that is, the number of times they are activated, and stores them as operation data. Further, the integrating time meter 15 integrates the closing time of the up-driving relay contact 12 and the down-driving relay contact 13, that is, the driving time of the car, and stores it as driving data.

On the other hand, in the monitoring center 2, a supervisor periodically checks the frequency meter 14 and the cumulative time meter 15 of the terminal device 1 at predetermined time intervals, or irregularly by a maintenance inspection worker scheduled to carry out maintenance inspection work. Monitoring center 2 for stored operating data

[0014] This comparator 22 is inputted with a limit value of operating data set in advance by a setting device 23, and the comparator 22 compares the input operating data with the limit value and determines the limit value. The results are displayed on a display or printer (not shown) or printed. For this reason, the monitors and maintenance inspection workers at the monitoring center 2 check the comparison data on the display and printer, and check the current need for maintenance inspection work and the expected date when maintenance inspection work will be required. can be grasped. Based on this comparative data, maintenance inspection workers go to the building site where the elevator that requires maintenance inspection is installed and perform tasks such as replacing the contacts of the magnetic contactor, replacing gear oil, and inspecting specific parts. In addition, if there is a building that has an elevator installed that does not require maintenance or inspection work at this time but is expected to require maintenance or inspection in the near future, we will schedule a visit to that building during the next maintenance inspection. and set a schedule.

Furthermore, a setting device 23 for operating data is provided.
If a number of years have passed since the last limit value was set by , and the elevator is old and the set value needs to be changed, the setting device 23 is operated at the monitoring center 2 to make the necessary change to the set value. be able to.

In this embodiment, the frequency meter 14 and the cumulative time meter 15 of each terminal device 1 can be controlled from the monitoring center side whenever desired.
