[0010] In the present disclosure, when the machine inspection results before and after the inspection work by the worker are recorded in the report, the device mechanically checks whether the machine inspection results have changed. For example, the device checks whether the machine inspection results have changed from a state exceeding a threshold that requires maintenance work by the worker to a normal state, and automatically records the result in the report. In addition, the device checks whether the worker is performing work related to the content of the machine inspection results to be recorded by uploading the work to the cloud from a maintenance terminal carried by the worker during work, and the content of the maintenance work to be performed by the worker becomes clear, and the worker can perform the maintenance work smoothly and accurately. In addition, the accuracy of the machine inspection results recorded in the report can be improved.

[0011] When including photos in a report, it is easy to clearly indicate which task the photo relates to and upload it, and it can be automatically posted in the appropriate location in the report.

[0012] In this specification, the maintenance work includes not only the adjustment work but also cleaning, part replacement, and other work.

[0013] FIG. 1 is an overall configuration diagram showing a schematic diagram of a system for monitoring and maintaining an elevator according to the present disclosure.

[0014] In this figure, the elevator 1 (elevator) includes an elevator car 11, a counterweight 12, a main rope 13, a hoist 14, an elevator control device 15 (elevator control device), and a tail cord 16. The elevator control device 15 is communicably connected to a monitoring terminal 21 and a maintenance terminal 31. This connection may be wired or wireless. The monitoring terminal 21 is connected to an elevator maintenance center 41 via a telecommunication line 22, and the maintenance terminal 31 is connected to an elevator maintenance center 41 via a telecommunication line 23. The elevator maintenance center 41 includes a machine inspection result database 42 and a report creation device 43. The maintenance terminal 31 can transmit data to a printer 51 for printing. In addition, data from the maintenance terminal 31 and the elevator maintenance center 41 can be transmitted to an output terminal 52.

[0015] The maintenance terminal 31 is preferably a portable terminal (a computer device such as a smartphone or tablet) that the worker can carry around. In this case, the worker can input numerical values, text, etc. to the maintenance terminal 31, and can also take and send photos. The worker can also receive data held by the monitoring terminal 21, the report creation device 43, etc., through the maintenance terminal 31.

[0016] Next, the maintenance work of the present disclosure and the process of creating a report associated with the work will be described with an example.

[0017] FIG. 2 is a flow diagram showing a part of a report creation process for a level checking operation, a sill groove cleaning operation, and a door switch inspection operation, which are examples of the maintenance operations according to the present disclosure.

[0018] First, when entry processing is performed on the maintenance terminal 31 at the start of work (step S1), the report creation device 43 registers the entry, identifies the work site from the registration information, and starts creating a report (step S2).

[0019] Next, when the maintenance terminal 31 registers that a level check operation will be performed (step S3), the report creation device 43 refers to past data stored in the machine inspection result database 42 and checks the measurement value of the machine inspection level at the work site (step S4). The report creation device 43 then determines whether the measurement value of the machine inspection level exceeds the abnormality determination threshold (step S5). Here, "abnormality" refers to a state in which a sign of a failure appears before a failure occurs, and is a state in which an operator should take action during inspection to prevent a failure. Furthermore, "machine inspection" refers to acquiring various measurement values ​​of the elevator by the monitoring terminal 21. Furthermore, "machine inspection result" refers to a predetermined measurement value among the remote monitoring data acquired by remotely monitoring the elevator.

[0020] Further, remote monitoring data acquired by remotely monitoring the elevator, settings and abnormality determination thresholds related to the elevator, and other accumulated data are stored in the machine inspection result database 42. The accumulated data includes the above-mentioned past data.

[0021] If the measurement value of the machine inspection level exceeds the abnormality determination threshold, the report creation device 43 notifies the maintenance terminal 31 of the measurement value (step S6). The maintenance terminal 31 receives the notification (step S7). This notification can be displayed on the maintenance terminal 31, and this display can be confirmed by the operator.

[0022] If the measurement value of the machine inspection level does not exceed the abnormality judgment threshold and is normal, no notification is made from the report creation device 43 to the maintenance terminal 31. In other words, if it is judged to be normal in step S5, the process proceeds to step S9.

[0023] Next, when the maintenance terminal 31 registers that the level confirmation work has been completed (step S8), the report creation device 43 checks the value of the elevator that is constantly inspected by the monitoring terminal 21 (step S9) and determines whether the value exceeds the abnormality judgment threshold (step S10).

[0024] If it is determined to be normal in step S10, the process proceeds to A shown in the figure. The process after A will be described with reference to Fig. 4. Note that the case where the abnormality determination threshold is exceeded in step S10 in Fig. 2 will be described later.

[0025] FIG. 4 is a flow diagram showing a report preparation process branched off from the process of FIG. 2 and relating to a level confirmation operation.

[0026] If the abnormality determination threshold is not exceeded and the result is normal in step S10 in Fig. 2 (proceed to A), the report creation device 43 determines whether the measurement value of the machine inspection level before the level confirmation work is normal as shown in Fig. 4 (step S101). If the measurement value of the machine inspection before the work exceeds the abnormality determination threshold in step S101, it is determined that the work has improved the condition, and upon completion of the level confirmation work, the measurement value of the machine inspection before the level confirmation work and the measurement value of the machine inspection after the work are reflected in the report, and the report is updated to reflect that the maintenance work including the adjustment work has been completed (step S102).

[0027] If the measurement value of the machine inspection before the work does not exceed the abnormality judgment threshold and is normal in step S101, the level confirmation work is completed and the measurement value of the machine inspection after the confirmation work is reflected in the report, and the work is completed (step S103).

[0028] After step S102 or step S103 is completed, the process proceeds to B. B is continued from step S13 in FIG.

[0029] If the abnormality determination threshold is exceeded in step S10 of FIG. 2, this is reflected in the report as a pre-report confirmation item (item to be confirmed) (step S11).

[0030] Next, sill groove cleaning and door switch inspection will be described as examples of work.

[0031] In the sill groove cleaning work, the start of the sill groove cleaning work is registered on the maintenance terminal 31 (step S12). The report creation device 43 accepts the start of the sill groove cleaning work (step S13).

[0032] The photographs taken during the work are sent from the maintenance terminal 31 to the report creation device 43 together with information indicating that the photographs are of sill groove cleaning work (step S14).

[0033] The report creation device 43 determines that the photograph is a photograph of the sill groove cleaning work and receives the photograph (step S15).

[0034] When the sill groove cleaning work is completed, the maintenance terminal 31 transmits a notice of the completion of the sill groove cleaning work to the report creation device 43 (step S16). The report creation device 43 receives the notice, and links the photograph received in step S15 to the sill groove cleaning work and reflects it in the report (step S17).

[0035] Next, moving on to the door switch inspection work, when the maintenance terminal 31 registers that the door switch inspection work will be performed (step S18), the report creation device 43 checks the measurement value of the machine inspection door switch operating position of the specific site from the machine inspection result database 42 (step S19). Then, it is determined whether the measurement value of the machine inspection door switch operating position exceeds the abnormality determination threshold value (step S20).

[0036] If the measurement value of the machine inspection door switch operating position exceeds the abnormality determination threshold in step S20, the report creation device 43 notifies the maintenance terminal 31 (step S21). The maintenance terminal 31 receives the notification (step S22). The worker can display and check the notification received by the maintenance terminal 31.

[0037] If the measured value of the machine inspection door switch operating position does not exceed the abnormality determination threshold and is normal in step S20, no notification is made from the report creation device 43 to the maintenance terminal 31. In this case, the process proceeds to step S24.

[0038] Next, when the maintenance terminal 31 registers that the door switch inspection work has been completed (step S23), the report creation device 43 checks the value of the elevator that is constantly inspected by the monitoring terminal 21 (step S24), and then determines whether the value exceeds the abnormality determination threshold (step S25).

[0039] If it is determined to be normal in step S25, the process proceeds to C shown in the figure. The process from C onwards will be described with reference to Fig. 5. Note that the case where the abnormality determination threshold is exceeded in step S25 in Fig. 2 will be described later.

[0040] FIG. 5 is a flow diagram showing a report creation process branched off from the process in FIG. 2 and relating to a door switch inspection operation.

[0041] If the abnormality determination threshold is not exceeded and the result is normal in step S25 in Fig. 2 (proceed to C), the report creation device 43 determines the measurement value of the machine inspection door switch operating position before the door switch inspection work as shown in Fig. 5 (step S201). If the measurement value of the machine inspection before the work exceeds the abnormality determination threshold, it is determined that the work has improved the condition, and when the door switch inspection work is completed, the measurement value of the machine inspection before the door switch inspection work and the measurement value of the machine inspection after the work are reflected in the report, and the maintenance work including the adjustment work is completed (step S202).

[0042] If in step S201 the measurement value of the machine inspection before the work does not exceed the abnormality judgment threshold and is normal, the measurement value of the machine inspection after the inspection work is reflected in the report upon completion of the door switch inspection work, and the work is reflected as completed in the report (step S203).

[0043] After step S202 or step S203 is completed, the process proceeds to D. D is continued from step S28 in FIG.

[0044] If the abnormality determination threshold is exceeded in step S25 of FIG. 2, this is reflected in the report as a pre-report check item (step S26).

[0045] When the entire inspection work is completed, the completion of the inspection work is registered on the maintenance terminal 31 (step S27). The report creation device 43 receives the registration of the completion of the inspection work (step S28) and proceeds to E shown in this figure. The steps after E will be described with reference to FIG.

[0046] FIG. 3 is a flow diagram showing the report creation process following FIG.

[0047] The report creation device 43 reflects the registered contents up to the registration of the completion of the inspection work in the report and automatically edits it (step S29). Then, the report creation device 43 checks and judges whether there are any pre-report check items (step S30). If there are any pre-report check items, it measures the corresponding machine inspection (obtains the measured value of the elevator) (step S31), checks the measured value, and judges whether there is an abnormality (step S32). If the measured value does not exceed the abnormality judgment threshold and is normal, it is judged that the work has improved the condition, and when the inspection work is completed, the measured value of the machine inspection before the work and the measured value of the machine inspection after the work are reflected in the report, and the maintenance work including the adjustment work is completed and reflected in the report (step S34). If the abnormality judgment threshold is exceeded, the measured value before the level check work and the measured value after the level check work are reflected in the report, and are set as pre-report check items (step S33).

[0048] Next, the report creation device 43 re-edits the contents of the report, completes the editing, and registers it (step S35).Then, the registered report is notified to the maintenance terminal 31 (step S36).

[0049] The maintenance terminal 31 receives the notification from the report creation device 43 (step S37).

[0050] The report received by the maintenance terminal 31 is checked by the worker and edited as necessary (step S38). After checking and editing, the worker registers the report in the report creation device 43 on the maintenance terminal 31 (step S39). The report creation device 43 receives the checked and edited report sent from the maintenance terminal 31 in step S39 and re-registers it (step S40).

[0051] The report transmitted by the worker from the maintenance terminal 31 in step S39 can be output using the printer 51 or the output terminal 52 (step S41).

[0052] Finally, the worker performs the exit process on the maintenance terminal 31 (step S42). The report creation device 43 receives and registers the exit information (step S43). This completes the series of steps.

[0053] FIG. 6 is a diagram illustrating an example of the report.

[0054] In this diagram, the site name, work date, and name of the person in charge of the work are written in the top column of the report. The contents written here automatically reflect the contents sent when the worker registers to enter the facility. The report contents include columns for work items to be performed, their results, and remarks. Here, the work items reflect the contents registered from the maintenance terminal 31. The results automatically reflect the results of measurements taken in machine inspections before and after work. The remarks automatically reflect the results of measurements taken in machine inspections. Here, "automatically" means that processing is carried out according to a program contained in the device, without the need for operation (manual operation) by the worker. The same meaning applies to "automatically."

[0055] The work items to be performed include checking the floor level, cleaning the sill groove, checking the door switch operating position, and checking the door open time.

[0056] The results of the floor landing level check clearly indicate that it has been completed and that adjustments have been made. In addition, a sentence explaining the meaning and reason for the adjustment is included, and any special details are indicated so that the customer can easily understand. The notes also include information indicating that, although the level was within the normal range (set value ±10mm) before the work, it exceeded the abnormality judgment threshold, so adjustments were made during the work to make it approximately the same as the set value, i.e., the results of measurements of the values ​​before and after the adjustments on each floor are included.

[0057] The result of the sill groove cleaning is that it was completed without any problems. In addition, in the remarks, a photograph (transmitted from the maintenance terminal 31) showing the cleaning status is displayed.

[0058] The results of the door switch operation position inspection indicate that the inspection was completed and that no abnormalities were found. In addition, the notes indicate numerical values ​​of the measurement results that did not exceed the abnormality judgment threshold.

[0059] The results of the door open time check indicate that a repair plan is necessary, specifically, that although it is currently normal and safe, it is recommended that the belt be replaced. Additionally, the notes state the normal value for the door open time and the measured value.

[0060] In addition, although no specific items are given, if the abnormality judgment threshold was exceeded before the work was carried out and the maintenance work carried out during the work was unable to bring it within the normal range (if the abnormality judgment threshold is exceeded after the work is carried out), it is stated that the work has been completed and that a repair plan must be planned (repair is proposed). In the notes, the normal value is listed along with the measured value so that the situation can be understood specifically.

[0061] Furthermore, in the comment input field, the operator can write any content that he or she thinks should be added. This content can be created by the maintenance terminal 31 and transmitted to the report creation device 43.

[0062] Preferred embodiments of the present disclosure will be described below.

[0063] In the elevator maintenance work report creation device, the necessity of maintenance work is determined by comparing the results of the machine inspection with an abnormality determination threshold value.

[0064] The photos sent from the maintenance terminal are posted in a designated location on the maintenance work report.

[0065] When a notification of the start of work is received from the maintenance terminal, the machine inspection result is compared with the abnormality determination threshold, and if an abnormality is found, the maintenance terminal is notified. [Explanation of symbols]
