For this reason, elevator maintenance is usually performed by a specialized maintenance company. The organization of such a maintenance company is different for each maintenance company.For example, a maintenance person is assigned to a sales office that performs maintenance of elevators in a certain area to perform maintenance of the elevators, and a plurality of sales offices are operated. A monitoring center for monitoring the elevators is provided to deal with important accidents of the elevators, and information on a plurality of monitoring centers (information on all elevators) is managed by the headquarters.

Conventionally, maintenance of an elevator is performed by a maintenance person at a sales office periodically (for example, once a month).
The inspection results were created as a report by hand and reported to the customer. Separately, the sales office regularly made a report on the presence or absence of a serious accident and reported it to customers.

[0004] In recent years, elevator operation control has been performed by a control device constituted by a microcomputer. Using the functions of the control device, data during normal operation of the elevator has been recorded. Diagnosis operation of each elevator is performed by a command from the monitoring center, and during this diagnosis operation, for example, elevator start time, acceleration traveling time, high-speed operation speed, speed fluctuation, landing level, and other various data are collected and are It is proposed to record. Such a system will be described with reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIG. 1 is a system configuration diagram of a work instruction creation system for an elevator failure sign according to an embodiment of the present invention. In the figure, the same or equivalent parts as those shown in FIG. The difference between the system of the present embodiment and the conventional system is that the communication device 26, the control unit 27, the storage unit 28, and the communication unit 29 provided in the monitoring center 2 use the usage state stored in the storage unit 23. Management department 4 for data, diagnostic data and predictive data
And a configuration of the management section 4. Thus, the communication device 26 of the monitoring center 2
The control unit 27, the storage unit 28, and the communication device 29 can easily implement the function of transmitting each data stored in the storage unit 23 to the management unit 4 without any explanation.

On the other hand, the management section 4 includes the same communication devices 41 and 45 and a storage section 43 as those of the related art, as well as a control section 46 having new functions and an extracted data storage section 40.
A, a data storage unit 40B, a customer information storage unit 40C, and a work data storage unit 40D.

The control unit 46 includes a central processing unit (CP)
U) 46a, a sign data extraction unit 46b, a customer information extraction unit 46c, and a conventional alarm data extraction unit 46d
Is provided. The CPU 46a performs necessary calculations and controls according to a program stored in a memory (not shown). Further, the sign data extraction unit 46b and the customer information extraction unit 4
6c, the alarm data extraction unit 46d is actually configured by a program stored in a memory (not shown). The extracted data storage unit 40A is configured by a magnetic disk or the like, and stores extracted data described later. The data storage unit 40B is a large-capacity storage device composed of a magnetic tape or the like, and sequentially stores and stores various types of transmitted data. The customer information storage unit 40C stores and stores detailed data of all customers of the maintenance company. The work data storage unit 40D
Stores work reports (work data) from each sales office.

The structure of the elevator 1 is the same as that shown in FIG. The configuration of the sales office 5 is basically the same as the configuration shown in FIG. 3, although the function of the control unit 52 and the configuration of the storage unit 53 shown in FIG. 3 are changed.

Next, the operation of this embodiment will be described. As in the conventional system, the storage unit 23 of the monitoring center 2 stores usage state data, diagnostic data, and predictive data,
The storage unit 25 stores alarm data, and the data stored in the storage units 23 and 25 is transmitted to the management unit 4 via the communication device 26, the control unit 27, the storage unit 28, and the communication device 29. You. CP of the control unit 46 in the management unit 4
U46a stores the transmitted diagnostic data, use state data, sign data, and alarm data in the storage unit 43. The storage unit 43 also stores test data of a communication system between the elevator 1 and the monitoring center 2.

In this way, the data taken out of the storage unit 14 of the elevator 1 at a time by the monitoring center 2 is stored in the storage unit 43.
The data is stored in the data storage unit 40B by the PU 46a and stored as the history of the elevator 1.

On the other hand, the predictive data extracting unit 46b
6a is instructed to take out only the predictive data from the data stored in the storage unit 43. Next, the customer information extraction unit 46c instructs the CPU 46a to extract necessary customer information (for example, a customer name or a building name of the elevator that generated the indication data) from the customer information storage unit 40C corresponding to each indication data. I do. Thus, the sign data extracted in accordance with the instruction from the sign data extracting unit 46b is in a state where the required customer information is added, and this data is stored in the extracted data storage unit 40A. Similarly, the alarm data stored in the storage unit 43 is also extracted and added with customer information in accordance with commands from the alarm data extraction unit 46d and the customer information extraction unit 46c, and stored in the extraction data storage unit 40A. .

Out of the data stored in the extracted data storage section 40A, the alarm data is subjected to the same processing as in the prior art. On the other hand, the following processing is performed on the predictive data. In the business office 5, the date when the monitoring center 2 periodically collectively retrieves data from the storage unit 14 of the elevator 1 is known. Therefore, when the input unit 55 instructs to take out the sign data at an appropriate time of the day, the control unit 52 accesses the extracted data storage unit 40A via the communication devices 51 and 45, and selects from among the stored sign data. Only the sign data of the elevator belonging to the own office is taken out and stored in the storage unit 53. In this case, customer information is added to each sign data as described above. Thus, the storage unit 53
The sign data stored in the storage device is compiled in an arbitrary form such as for each same customer or each same building, and based on this, the printing apparatus 54 uses the sign signal maintenance work instruction (work instruction).
Is printed.

The maintenance staff at the sales office 5 refers to the work instruction for the elevator in charge of itself and adds the work specified by the work instruction to the work at the next round maintenance work. As a result, it is possible to prevent the occurrence of a failure that was warned by the sign data.

FIG. 2 is a diagram showing an example of the work instruction sheet. The example of this figure relates to the landing level data shown in the example c of the indication data earlier. The sign data in this case is “implantation level abnormality” (corresponding to the code “0180” of “YCD” meaning the kind of sign data in the figure),
"Actual level difference" (in the figure, "1
5mm ")," Detection date and time "," Detection floor "
(The figure shows an example in which an abnormal landing level is detected on the eighth floor.) Each item in the work instruction sheet is stored as data in the storage unit 53, and the content data of each item of “predictive signal name / content”, “measurement data name”, and “inspection instruction item” is “YC
The code is stored in the storage unit 53 in advance in association with the code “D”. Therefore, when the indication data is input, the work instruction can be printed and created.

In FIG. 2, "number" is the number assigned to the corresponding elevator, and "measurement data" is 15 mm, and the landing level which should be within the set value ± 10 mm is 15 m.
m, indicating that it is out of the allowable range, and the “contents of the inspection instruction item” indicates an inspection location for an abnormal landing level. In the section of "inspection results and countermeasures", the maintenance staff goes to the elevator for the landing level abnormality and enters the results of the inspection according to the contents of "inspection instruction items".

The maintenance person finishes the inspection according to the work instruction as shown in FIG. 2, and fills in the item of "inspection result and countermeasure contents". The office confirms that the inspection has been completed by referring to the entry, and inputs this to the input unit 55. The control unit 52 transmits the checked data corresponding to the sign data of the elevator to the work data storage unit 40 via the communication devices 51 and 45.
Store in D. At an appropriate time, the control unit 46 of the management unit 4 stores the indication data transmitted this time and the work data storage unit 4
By comparing the data stored in 0D with the unchecked predictive data as unchecked data, the unchecked data is sent to the sales office in charge to prompt the check, thereby preventing omission of the check.

As described above, in the present embodiment, the customer information storage section is provided in the management section, and necessary customer information corresponding thereto is added to the transmitted sign data.
This eliminates the need for collating the sign data with the customer at the sales office. Further, since all the processing of the sign data is performed by the management department, the work of the monitoring center can be reduced, and the obstruction of the monitoring function inherent in the monitoring center can be prevented. Further, since a method of dealing with the predictive data is clearly indicated by a document, it is possible to accurately perform maintenance for a failure that may occur in the future, and to prevent the failure before and surely. be able to.

Further, a data storage section is provided in the management section to store and store the sign data, so that it can be used for diagnosis of elevators, determination of parts replacement and the like.

Furthermore, it is confirmed whether or not the work instructed by the work instruction is performed, and if the work is not performed, a warning is issued. Therefore, it is possible to reliably prevent a future failure due to the work not being performed. Can be.

[0035]

As described above, according to the present invention, the customer information is added to the sign data in the management department, so that the labor and time for collating the sign data and the customer information in the sales office can be saved. it can. Further, since the processing of the sign data is performed not by the monitoring center but by the management department, the work of the monitoring center is reduced and the monitoring function is not hindered.
Further, since the sign data is printed, the maintenance staff of the sales office can surely grasp the sign data.
