When the automatic diagnosis operation command is received from the control unit 22 of the monitoring center 2 via the communication devices 21a and 3, the elevator 1 is diagnosed according to a predetermined program, and the data (diagnosis data) obtained during this diagnosis operation is stored. It is stored in the unit 13. As a result, the storage unit 13 stores the diagnostic data and the usage state data. The report data is only temporarily stored in the storage unit 13, and is deleted after the report is issued. The control unit 22 of the monitoring center 2 periodically, for example, once a month, retrieves the usage state data and the diagnostic data stored in the storage unit 13 and stores them in the storage unit 23.

[0013]

When the above-mentioned proposed means is used, the monitoring center 2 can automatically store the usage status data and the diagnostic data. Therefore, by analyzing these data. Items that can be effectively maintained, maintenance personnel at the sales office 5 do not have to perform patrol maintenance of the elevator in charge, and automatic maintenance inspection cannot be performed.
For example, it is only necessary to check the subtle ride comfort of the elevators, etc., and efficient maintenance can be performed, and it is not necessary to increase the number of maintenance personnel even if the number of elevators increases.

However, in such a system, it is impossible for the customer to know whether or not maintenance is performed,
This creates anxiety, and such customer anxiety becomes an important issue for maintenance companies that may lead to a decline in credit.

An object of the present invention is to solve the above problems in the prior art, and to provide an elevator usage condition and diagnostic result report preparation system which can secure the customer's trust while suppressing the number of maintenance personnel visiting. Especially.

Next, the operation of this embodiment will be described. As in the conventional system, the storage unit 23 stores the usage state data and the diagnostic data, the storage unit 25 stores the alarm data, and the data stored in the storage units 23 and 25 are the communication device 26 and the control unit. It is transmitted to the management department 4 via the unit 27, the storage unit 28, and the communication device 29. Control unit 4 of management department 4
In 6, the CPU 46a stores the transmitted diagnostic data, use state data, and alert data in the storage unit 47. The storage unit 47 also stores test result data of the communication system between the elevator 1 and the monitoring center 2.

In this way, the data is successively accumulated in the storage unit 47. In this state, the diagnosis result data extraction unit 46b and the usage state data extraction unit 46c cause the CPU 46a to periodically (periodically) store the diagnosis data stored in the storage unit 47 for each customer (each elevator). And a command to extract predetermined diagnostic data and use state data from the use state data and store them in the extracted data storage unit 48. Similarly, the report data extraction unit 46d also issues a report to the CPU 46a. It is instructed to extract the data and store it in the extracted data storage unit 48. At this time, each customer code and the machine number of each elevator are set in the extracted data storage unit 48, and the extracted data is stored in the area corresponding to them.

The predetermined period in the above data extraction is
For example, it is set to a period in which the maintenance staff regularly reports to the customer, and therefore the extracted data is the data accumulated from the date of the previous report to the date of this report. The actual date of data extraction is, for example, the day before the regular report.

As an example of the diagnostic data and the usage status data extracted above, "presence or absence of confinement failure",
"Presence or absence of unbootable failure", "Presence or absence of safety device operation",
"Abnormality of power supply system", "Abnormality of door opening and closing",
There are "abnormality in elevator operation management" and "whether there is a report from inside the car". Furthermore, as usage status data with numerical values, "number of times used by floor", "number of times car calls occur", "landing place" There are “number of calls generated”, “number of times the door is opened and closed”, etc.

At the business office 5, on the day before the day when the maintenance staff visits the customer for regular reporting (data extraction), the control section 52 is instructed to take out the data of the customer.
The control unit 52 includes the communication device 51 of the sales office 5 and the management department 4.
The extracted data storage unit 48 is accessed via the communication device 45, the elevator data of the customer is taken out, stored in the storage unit 53 once, and then printed by the printing device 54.

The reporting period is fixed, for example, from the first day of every month.
For customers who report at the end of the month, there is also a method of collectively implementing the above-mentioned means on the first day of the next month and bringing it to the customer or reporting by mail.

FIGS. 2, 3 and 4 are views showing an example of a report printed by the printing device 54. FIG. 2 is a report of a result of monitoring whether or not there is an abnormality, and FIG. 3 is usage state measurement data. 4 is a report of the driving performance and the diagnosis result of the apparatus, and these are created based on the data stored in the storage unit 53.

The report shown in FIG. 2 is a report of the extracted data exemplified above, and in particular, regarding the presence or absence of an unstartable failure, there is a report and its report data (issued by the management department 4). The data extracted by the report data extraction unit 46d) is shown. The report illustrated in Figure 2
It is created based on the extracted usage status data, diagnostic data, and reporting data.

The report shown in FIG. 3 shows, for each floor, the number of times of use, the rate of use, the number of times of car calls, the rate of occurrence, the number of times of landing calls, the average time, the number of times of opening and closing of doors, and the number of times of inversion of car calls. The customer uses this report for various purposes such as grasping the usage status of the entire building. This report is prepared based on the usage status data. The report contents shown in FIGS. 2 to 4 can be printed on one sheet in order to make it easy for the customer to see.

The report shown in FIG. 4 is a report of the most basic measured values of the operating performance of the elevator and the diagnostic results of the main equipment that is visible to the outside. For the former, the measured values at a prescribed date and time, and The result of comparison between the measured value and the reference value is shown, and for the latter, the judgment result is shown. This report is prepared based on the diagnostic data.

As described above, in this embodiment, the required data is automatically extracted from the usage state data and the diagnostic data, a report is created together with the report data, and this report is submitted to the customer. As a result, it is possible to secure the customer's trust while minimizing the number of maintenance staff visits, and it is possible to create a report without manpower.

The data to be extracted from the usage state data and the diagnostic data is not limited to the above example, and can be set arbitrarily, and the format of the report can be set arbitrarily. Further, in many cases, a system in which the maintenance staff always visits the site when a report is issued and performs a predetermined process and reports this to the customer is not necessarily required to report the report data.

[0035]

As described above, according to the present invention, the required data is extracted from the usage condition data and the diagnostic data to create a report, and the report is submitted to the customer. It is possible to keep the customer's trust while minimizing the number of personnel visits, and to create a report without requiring human intervention.
