Description

  The present invention relates to an apparatus for remotely monitoring the state of an elevator.

  Conventionally, an elevator remote management system that centrally monitors the status of elevators in a plurality of buildings at a remote management center or the like is known. For example, the facility diagnosis apparatus disclosed in Patent Document 1 stores detection data obtained by detecting process values of various facility devices in a building and failure data of each device in a database. Then, when a certain device breaks down, the trend until it deviates from the normal value is analyzed based on the history data related to the device, and a parameter that is determined to be abnormal is obtained. Furthermore, the failure is predicted in advance by monitoring the frequency distribution created from the measurement data of the same type and almost the same specification equipment using the above parameters. For example, for a predetermined device, a frequency distribution of the difference value between the set value and the actual value is created, and the number of times that the difference value is included in a predetermined band of the frequency distribution is counted. A failure alarm is notified.

  In addition, the maintenance work support device disclosed in Patent Document 2 diagnoses the presence or absence of a failure of the elevator from the time difference between the ideal timing and actual timing of each operation of the elevator.

The monitoring device includes a specification storage unit, a similar elevator extraction unit, a diagnostic operation command unit, and a determination unit. The specification storage unit stores specifications of a plurality of elevators. When a failure signal is received from an arbitrary elevator control device, the similar elevator extraction unit extracts a similar elevator having at least one of the specification items in common with the failure signal source elevator based on the specification storage unit. The diagnostic operation command unit instructs the similar elevator to execute a diagnostic operation. The determination unit determines whether maintenance inspection is necessary based on the result of the diagnostic operation.

  Moreover, in the said invention, when performing a diagnostic driving | operation with respect to a similar elevator, you may provide the threshold value change part which changes the threshold value which divides a normal value and an abnormal value into the normal value side.

  The elevator specification data 371 (specification storage unit) has a data structure for storing specification item data such as the control number, model, date of manufacture, manufacturing number, name of the installed building, use of the installed building, and the like of the elevator 20. For example, the model information is classified according to the type, such as for high-rise and low-rise buildings, model information sorted according to usage such as residential and apartment buildings, and whether the elevator in the hoistway is exposed to sunlight. The model information sorted according to the situation is reflected. The use of the installed building is, for example, an office, a general residence, a restaurant, a school, and the like.

  The elevator specification data 371 has a data structure for storing data on the installation environment and the number of times of rope bending. The installation environment is data indicating whether or not each device of the elevator 20 is easily deteriorated, such as a hot spring area, a coastal area, and a factory. The number of times of rope bending is data indicating the number of times the wire 23 is bent by the sheave. In addition, hoistway height data may be included.

  The inspection history data 372 has a data structure for storing the management number of the elevator 20, the date and time of the inspection conducted by the engineer 350 at the site, inspection items, and inspection result data. The inspection includes, for example, inspection of the open / closed state of the doors 13 and 26 of the elevator 20 shown in FIG. 1, inspection of the stop position of each floor (inspection of the height deviation between the floor 12 and the floor 27 of the cage 22), wire 23 inspection, traveling speed inspection, and the like. In addition, whether or not an abnormality has been found as a result of the inspection, whether an abnormality has not been found but maintenance work such as cleaning is necessary, or parts need to be replaced soon are input as the inspection result. In FIG. 1, reference numeral 25 denotes a weight.

  The maintenance work history data 373 has a database structure for storing the management number of the elevator 20, the maintenance work date / time of the elevator 20 performed by the engineer 350 at the site, maintenance work items, and maintenance work results. The maintenance work items include, for example, inspection of the operation state of the elevator 20, cleaning of the door rail of the elevator 20, refueling to the driving device 24 shown in FIG. 1, adjustment of the brake of the elevator 20, and the like. The results of maintenance, cleaning, refueling, adjustment, etc. are entered in the maintenance work results.

  The remote inspection history data 374 has a data structure for storing a management number of the elevator 20, a remote inspection date, a remote inspection item, and a remote inspection result. The remote inspection of the elevator 20 is also referred to as remote diagnosis as will be described later. For example, when the elevator 20 is selected according to a preset schedule such as once a month or as a similar elevator as described later, This is performed by the control panel 210. The control panel 210 of the elevator 20 moves the cage 22 of the elevator 20 shown in FIG. 1 to a predetermined floor. During this movement, various sensors attached to the elevator 20 are checked for abnormalities in driving performance (acceleration, presence or absence of abnormal noise), door opening / closing, brakes, emergency batteries, external communication devices, and the like. The inspection result is stored in the remote inspection history data 374 from the information processing device 360 via the communication devices 250 and 320 and the communication network 30. Note that, as will be described later, in the remote inspection (remote diagnosis), an execution command is output by the diagnostic operation command unit 402 of the information processing device 360.

  The modulation history data 375 has a data structure for storing a management number of the elevator 20, a modulation occurrence date and time, a modulation item, and a modulation correspondence result. The modulation of the elevator 20 refers to a case where the result of the inspection, inspection, maintenance work or remote inspection by the engineer 350 does not reach the abnormal value but changes from the normal value of the elevator 20. . In other words, the intermediate state provided between normal and abnormal is modulation. For example, as a result of checking the traveling speed, the value is within the allowable value, but when the previous check or when the deviation of the elevator 20 from the value of the previous check result is large, the modulation item Recorded as “traveling speed”.

  The repair work history data 376 has a data structure for storing the control number of the elevator 20, repair work date and time, repair work items, repair work results, and replacement parts. The repair work is a restoration work by replacement of parts such as replacement of the wire 23, replacement of the hanger roller, replacement of the brake pad, replacement of the control board, and replacement of the relay. Therefore, the name of the replacement part such as “wire replacement”, “hanger roller replacement”, “brake pad replacement”, etc. is entered in the repair work item, and “repair work completed”, “re-repair” are entered in the repair work result column. Items such as “Necessary” are entered. Items such as “wire”, “hanger roller”, and “brake pad” are input to the replacement part.

  The failure history data 377 has a data structure for storing a management number of the elevator 20, a failure occurrence date and time, a failure code, a recovery method, and a recovery determination result. The failure code is a code output from the control panel 210 when a failure occurs in the elevator 20 or a combination of numbers and English letters. The types of failure codes are, for example, about 1000 types. For example, when the engineer 350 is dispatched to perform inspection, inspection, and recovery, the restoration method item is input as “engineer dispatch”. Further, in the item of the recovery method, for example, when the remote recovery system 100 recovers, “Remote recovery” is input. In the item of the restoration determination result, when the elevator 20 is restored and the operation is resumed, “Recovery” is input. In addition, in the item of the restoration determination result, when the elevator 20 fails to be restored, “failure” is input.

  The failure factor-specific data 378 includes the number of failure factors corresponding to the failure code as a result of inspection and inspection by the engineer 350 when a certain failure code is output from the control panel 210, and remote Stored is the total number of failure factors corresponding to the failure code when the recovery system 100 recovers. For example, when the failure code is 0001 indicating a failure related to the doors 13 and 26, the engineer 350 inspected the site, and as a result, the cause of the output of the failure code “0001” is the clogging of the door sill (failure factor 1). Or a contact failure of the switch of the door opening / closing device (failure factor 2), or other failure factor 3. Therefore, the failure factor-specific data includes 100 cases of a door clogging factor (failure factor 1) when a failure code “0001” is output, and a contact failure of the door opening / closing device switch (failure factor 2). ) In the data structure such that 50 cases and other failure factor 3 cases are 10 cases, and the data is arranged in descending order of the number of cases. In the case of recovery by the remote recovery system 100, when the elevator 20 is successfully recovered by the recovery command, the number of failure factors corresponding to the failure code that is the basis of the recovery command is added to the total number of failure factors.

  The operation history data 379 stores data of operation rate, landing door opening / closing frequency, basket door opening / closing frequency, stop times, travel distance, total travel time, and startup frequency. The operation rate is obtained from MTBF / (MTBF + MTTR) using an average failure interval (MTBF) indicating a time between failures and an average repair interval (MTTR) which is an average of time required for repair. The number of times of opening / closing the landing door is recorded for each floor. As the number of times of opening / closing the cage door, the number of times of opening / closing the door 26 of the cage 22 is recorded. As the stop times, the number of stops of the basket 22 is recorded for each floor. As the travel distance, the total travel distance of the basket 22 is recorded. The total traveling time of the car 22 is recorded as the total traveling time. The number of activations is counted as one time from the engagement (braking) of a brake (not shown) to the next engagement, and the total count is recorded.

  As shown in FIG. 4, the restoration diagnosis database 380 includes a restoration diagnosis instruction set that is a set of restoration instructions and restoration diagnosis instructions in descending order of the number of failure causes in the failure cause-specific data 378, and elevators by executing the restoration instructions. Stored is a recovery rate (%), which is the rate at which 20 failures have been recovered. The restoration diagnosis database 380 is a database in which the restoration diagnosis command set and the restoration rate are linked to the failure factor-specific data 378 described above.

  Hereinafter, the data configuration of the recovery diagnosis database 380 when the failure code is “0001” indicating a failure related to the doors 13 and 26 will be described. If the door sill is clogged (Failure factor 1), the restoration diagnosis data will be “Failure factor 1”, “Door circuit reset + door high torque open / close” as the restoration command, and “Door open / close diagnostic” as the restoration diagnostic command. The data structure is such that a recovery diagnosis command set A, which is a set of two commands, and a recovery rate x% by a recovery operation by this recovery command are linked. Similarly, when the contact failure of the door opening / closing device switch is the cause (failure factor 2), the restoration diagnosis data is “door circuit reset + door opening / retry retry” as the restoration command in the number of failure cause 2 data, restoration diagnosis. The data structure is such that a recovery diagnosis command set B, which is a set of two commands of “door opening / closing diagnosis”, and a recovery rate y% of the recovery operation by this recovery command are linked as commands. Similarly, in the case of the failure factor 3, the recovery diagnosis data has a data configuration in which the recovery diagnosis command set C and the recovery rate z% are linked to the number data of the failure factor 3. As described above, the recovery diagnosis database 380 includes the failure code, the failure factor corresponding to the failure code, the number of the failure factors, the recovery diagnosis command set that is a set of the recovery command and the recovery diagnosis, and the recovery rate. It is stored in the database in association. In this embodiment, the recovery rate y% is a larger value than the recovery rates x% and z%, and the recovery diagnosis command set B has a higher recovery rate than the recovery diagnosis command set A and the recovery diagnosis command set C. ing.

  Hereinafter, the operation of the remote recovery system 100 when a failure signal is transmitted from the elevator 20 will be described with reference to FIGS. 2, 5, and 6. In the following description, the remote recovery operation when the failure code signal “0001” regarding the doors 13 and 26 is first transmitted will be described. Next, a remote recovery operation when a failure code “0002” related to a control circuit incorporated in the control panel 210 is transmitted will be described. Next, the remote recovery operation when a failure code “0003” related to the brake in the drive unit 24 is transmitted will be described. The remote recovery system 100 can also cope with a case where a failure code related to a part other than the above is transmitted.

  As shown in step S <b> 101 of FIGS. 2 and 5, the control panel 210 of the elevator 20 determines whether or not a failure has occurred in the elevator 20. When a failure relating to the doors 13 and 26 of the elevator 20, for example, a failure such as a door opening / closing failure, the control panel 210 displays a failure code “0001” indicating the failure occurrence date and time and the failure is a failure relating to the door. Output to 250. If no failure occurs in the elevator 20, the control panel 210 returns to the beginning of step S <b> 101 and continues monitoring the elevator 20.

  When the failure code “0001” is input from the control panel 210, the communication device 250, as shown in step S102 of FIGS. 2 and 5, includes the failure code “0001”, the management number of the elevator 20, and the failure occurrence date and time. A signal is transmitted to the communication network 30. 2 and 5, the communication device 320 of the remote monitoring center 310 receives the failure signal transmitted from the communication device 250 via the communication network 30. When receiving the failure signal, the communication device 320 outputs the failure code “0001” included in the failure signal, the management number of the elevator 20, and the failure occurrence date and time to the information processing device 360. The information processing apparatus 360 stores the input failure code “0001”, the management number of the elevator 20, and the failure occurrence date / time in the failure history data 377 of the maintenance database 370.

  Then, the information processing apparatus 360 determines whether or not the failed elevator 20 can be remotely recovered, as shown in step S104 of FIG. As shown in FIGS. 2 and 3, the information processing device 360 acquires the model, manufacturing date, and manufacturing number of the elevator 20 from the elevator specification data 371 using the management number of the elevator 20. Based on the acquired specification data, the information processing device 360 confirms whether the elevator 20 has a specification that allows a recovery operation and a recovery diagnosis operation based on a recovery command and a recovery diagnosis command from the remote recovery device 300. When the elevator 20 is a model incapable of remote recovery operation, the information processing device 360 outputs a signal notifying the remote monitoring center 310 that remote recovery is impossible, as shown in step S124 in FIGS. To do.

Further, as shown in FIG. 2, the information processing apparatus 360 refers to inspection history data 372, maintenance work history data 373, remote inspection history data 374, modulation history data 375, repair work history data 376, and failure history data 377. Then, the following (a) to (f) are confirmed. (A) The elevator 20 has been instructed to re-adjust in a recent inspection.
(B) The elevator 20 has a maintenance plan recently or on the day, and the possibility of misadjustment is predicted.
(C) There was an abnormality diagnosis result in the elevator 20 by remote inspection.
(D) Recently, the elevator 20 has been modulated.
(E) The elevator 20 has recently been repaired.
(F) The elevator 20 has recently transmitted a failure signal with the same failure code “0001”.

  If any one or more of the above (a) to (f) is applicable, the information processing apparatus 360 should dispatch the engineer 350 to the building 10 rather than the recovery by the remote recovery system 100. And NO is determined in step S104 of FIG. 2 and 5, the information processing apparatus 360 outputs a notification that remote recovery is not possible to the remote monitoring center 310.

  Furthermore, the information processing apparatus 360 confirms whether the building 10 is a building with many erroneous transmissions of failure signals from the elevator specification data 371 and the failure history data 377 using the management number of the elevator 20. In such a case, the information processing apparatus 360 determines that it is better to dispatch the engineer 350 to the building 10 than the recovery by the remote recovery system 100 because there is a high possibility of erroneous transmission of a failure signal. 5 is judged NO. Then, the information processing apparatus 360 outputs a remote recovery impossible notification to the remote monitoring center 310 as shown in step S124 of FIGS.

  The notification that remote recovery is not possible, which is output from the information processing device 360 to the remote monitoring center 310, is displayed on the display 331 of the remote monitoring center 310 as shown in FIG. After confirming this display, the supervisor 334 causes the elevator 20 to stop operating and announce as shown in step S125 of FIGS. 2 and 6. Then, the supervisor 334 instructs the service center 340 in the vicinity of the building 10 to dispatch the engineer 350 to the building 10 by the telephone 333 as shown in step S126 of FIGS.

  When it is determined in step S104 in FIG. 5 that the elevator 20 cannot be remotely restored, the information processing apparatus 360 displays the input failure code “0001”, the management number of the elevator 20, and the failure occurrence date and time in the maintenance database in step S103. The failure history data 377 of 370 is stored. Then, the information processing apparatus 360 ends the remote recovery operation without updating other data in the maintenance database 370 and updating the recovery diagnosis database 380.

On the other hand, in step S104 shown in FIG. 5, the information processing apparatus 360, as shown in FIG. 2, the inspection history data 372, the maintenance work history data 373, the remote inspection history data 374, the modulation history data 375, and the repair work history data 376. The following (g) to (n) are confirmed with reference to the failure history data 377.
(G) It is a specification that allows the elevator 20 to perform a recovery operation and a recovery diagnosis operation by a recovery command and a recovery diagnosis command from the remote recovery device 300.
(H) The elevator 20 has not been instructed to re-adjust in a recent inspection.
(I) The elevator 20 has no maintenance plan recently or on the day, and the possibility of misadjustment is not predicted.
(J) There is no abnormality diagnosis result in the elevator 20 by remote inspection.
(K) Recently, there is no modulation in the elevator 20.
(L) The elevator 20 has not been repaired recently.
(M) The elevator 20 has not recently transmitted a failure signal with the same failure code “0001”.
(N) The building 10 is not a building with many false signal transmissions.

  If all the requirements (g) to (n) are satisfied, the information processing apparatus 360 determines YES in step S104 shown in FIG. 5 and starts remote recovery in the remote monitoring center 310 in step S105. Notice. This signal is displayed on the display 331 of the remote monitoring center 310. As a result, the supervisor 334 of the remote monitoring center 310 is notified that the remote recovery of the elevator 20 is started.

  When the information processing apparatus 360 notifies the remote monitoring center 310 of the start of remote recovery in step S105, the information processing apparatus 360 proceeds to step S106 shown in FIG. 5 and selects a recovery instruction and a recovery diagnosis instruction corresponding to the failure code “0001”. As described above with reference to FIG. 4, the recovery diagnosis database 380 is a database in which the recovery factor instruction data and the recovery rate are linked to the failure factor-specific data 378. Hereinafter, the data configuration of the recovery diagnosis database 380 when the failure code is “0001” indicating a failure relating to the doors 13 and 26 will be briefly described again. When the door sill is clogged (Failure factor 1), the restoration diagnosis data is “door circuit reset + door high-torque opening / closing” as the restoration command, and “door opening / closing” as the restoration diagnosis command. This is a data structure in which a recovery diagnosis command set A, which is a set of two commands “diagnosis”, and a recovery rate x% by a recovery operation by this recovery command are linked. Similarly, when the contact failure of the door opening / closing device switch is the cause (failure factor 2), the restoration diagnosis data is “door circuit reset + door opening / retry retry” as the restoration command in the number of failure cause 2 data, restoration diagnosis. The data structure is such that a recovery diagnosis command set B, which is a set of two commands of “door opening / closing diagnosis”, and a recovery rate y% of the recovery operation by this recovery command are linked as commands. Similarly, in the case of failure factor 3, the restoration diagnosis data has a data configuration in which the restoration diagnosis command set C and the restoration rate z% are linked to the number of cases of failure factor 3. Further, as described above, the recovery rate y% is larger than the recovery rates x% and z%, and the recovery diagnosis command set B has a recovery rate higher than that of the recovery diagnosis command set A and the recovery diagnosis command set C. It is high.

  The information processing device 360 may select, as a recovery command, a command corresponding to the failure factor having the largest number of cases among the plurality of failure factors corresponding to the failure code “0001”. Further, the information processing apparatus 360 may select a command having the highest recovery rate among a plurality of commands corresponding to the failure code “0001” as a recovery command. Then, the information processing device 360 selects a restoration diagnosis command set that is set together with the restoration command selected by the restoration diagnosis command corresponding to the selected restoration command.

  First, a case will be described in which the information processing apparatus 360 selects a command corresponding to a failure factor having the largest number of cases among a plurality of failure factors corresponding to the failure code “0001” as a recovery command. The information processing apparatus 360 refers to the recovery diagnosis database 380 and confirms the failure factor having the largest number of cases when the failure code is “0001” as the recovery instruction. Then, the information processing apparatus 360 performs a restoration operation for executing a restoration operation corresponding to the garbage clogging of the door sill (fault factor 1) which is the most frequent failure factor, “door circuit reset + door high torque opening / closing”, A restoration diagnosis command set A including two “door opening / closing diagnosis” which is a restoration diagnosis command for executing a restoration diagnosis operation corresponding to the result of the restoration operation is selected.

  Next, a case where the information processing apparatus 360 selects a command having the highest recovery rate among a plurality of commands corresponding to the failure code “0001” as a recovery command will be described. The information processing apparatus 360 refers to the recovery diagnosis database 380 and confirms the recovery rate with the highest recovery rate corresponding to the failure code “0001” as the recovery command. Then, the information processing apparatus 360 performs a restoration command for executing a restoration operation corresponding to the factor (failure factor 2) caused by the contact failure of the switch having the highest restoration rate y%, “door circuit reset + door opening / closing retry”, A restoration diagnosis command set B including two “door opening / closing diagnosis” which is a restoration diagnosis command for executing a restoration diagnosis operation corresponding to the result of the restoration operation is selected.

  When selecting a recovery diagnosis command set, the selection of whether to be based on the most frequent failure factor corresponding to the failure code “0001” or based on the recovery rate of the recovery diagnosis command set corresponding to the failure code “0001” is as follows: You may do as follows. For example, of the ratio of the maximum number of cases to the next number of cases (number of cases ratio) and the ratio of the maximum recovery rate and the next recovery rate (recovery rate ratio), You may select the one where the maximum value protrudes. Further, for example, if the previous remote recovery has failed, a different selection method may be used. Further, the selection of the restoration diagnosis command set may be determined by, for example, the model and specification of the elevator 20.

  In the following description, a case will be described in which the information processing apparatus 360 selects the restoration diagnosis instruction set A based on the failure factor 1 having the largest number corresponding to the failure code “0001”.

  When the restoration diagnosis command set A is selected in step S106 in FIG. 5, the information processing apparatus 360 transmits the selected restoration diagnosis command set A from the communication device 320 as shown in step S107 in FIGS. 2 and 5. 2 and 5, when receiving the recovery diagnosis command set A from the communication device 320, the communication device 250 outputs the recovery command and the recovery diagnosis command to the control panel 210.

  First, as shown in step S109 of FIG. 5, the control panel 210 determines that the elevator 20 is stopped, the weight sensor of the cage 22, the camera in the cage 22, the output of the person sensor in the cage 22, etc. Make sure there are no passengers inside. When the control panel 210 confirms that the elevator 20 is stopped and that there are no passengers in the basket 22, the control panel 210 "starts remote recovery from now on" from the speaker of the communication device installed in the basket 22. The elevator door will open and close. "

  When the announcement ends, the control panel 210 proceeds to step S110 in FIG. 5 and executes a recovery operation according to the recovery command. Since the received restoration command is “door circuit reset + door high torque opening / closing” which is a restoration command for executing a restoration operation corresponding to the garbage clogging of the door sill (fault factor 1), the control panel 210 First, the door circuit of the control panel 210 is reset. This operation resets the state in which the door circuit cannot open or close the door 13 or the door 26 and detects the open (or closed) state or the half-open (or half-closed) state, and opens or closes the door 13 or the door 26. This is a possible operation. Next, the control panel 210 increases the torque of the drive motor for the door 13 and the door 26 by 20 to 30% from the normal value, and opens and closes the door 13 and the door 26 with a force larger than normal. This operation is an operation in which the garbage stuck in the door sill is moved from the sill and the opening / closing operation of the doors 13 and 26 is restored to the normal state. As shown in step S111 of FIG. 5, the control panel 210 restores the garbage stuck in the thresholds of the doors 13 and 26 to check whether the doors 13 and 26 have been opened and closed. “Door open / close diagnosis” which is a diagnosis command is executed. The control panel 210 opens and closes the door 13 and the door 26 with a normal torque, and can the opening and closing operation be performed within a predetermined opening / closing time, or whether the current of the drive motor for the door 13 and the door 26 is larger than usual. Confirm. Next, the control panel 210 opens and closes the door 13 and the door 26 by reducing the torque of the drive motor by about 20% from the normal state, and checks whether there is any abnormality in the opening and closing time.

  When the control panel 210 determines that the doors 13 and 26 have been restored to the normal state by the restoration diagnosis operation, as shown in step S112 in FIG. 5, the process proceeds to step S113 in FIG. In step S113, the control panel 210 outputs a determination result signal that the elevator 20 has been restored. This signal is transmitted from the communication device 250 to the communication network 30. The transmitted determination result signal is received by the communication device 320 as shown in step S <b> 114 of FIG. 6, and the determination result is input to the information processing device 360. The determination result is notified from the information processing apparatus 360 to the remote monitoring center 310 as shown in step S115 of FIG. 6, and the result is displayed on the display 331 of the remote monitoring center 310. When the monitor 334 of the remote monitoring center 310 confirms this display, as shown in step S116 of FIG. 6, the operation of the elevator 20 is resumed and an announcement operation is performed. Further, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in steps S117 and S118 of FIG.

  On the other hand, if the result of the recovery diagnosis operation is NO in step S112 of FIG. 5, the control panel 210 proceeds to step S119 of FIG. In step S119, the control panel 210 outputs a determination result signal indicating that the restoration of the elevator 20 has failed. This signal is transmitted from the communication device 250 to the communication network 30. The transmitted determination result signal is received by the communication device 320 as shown in step S120 of FIG. 6, and the determination result is input to the information processing device 360. Further, the determination result is notified from the information processing apparatus 360 to the remote monitoring center 310 as shown in step S121 of FIG. 6, and the result is displayed on the display 331 of the remote monitoring center 310. After confirming this display, the supervisor 334 causes the elevator 20 to stop operating and announce as shown in step S122 of FIG. In addition, the supervisor 334 instructs the service center 340 near the building 10 to dispatch the engineer 350 to the building 10 by the telephone 333 as shown in step S123 of FIGS. Further, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in steps S117 and S118 of FIG.

  When the determination signal that the elevator 20 has been restored as shown in step S113 of FIG. 5 is input, the information processing apparatus 360 updates the maintenance database 370 as follows.

  When a determination signal indicating that the elevator 20 has been recovered as shown in step S113 of FIG. 5 is input, the information processing apparatus 360 displays “remote recovery” in the recovery method item of the failure history data 377, and the recovery determination result. Store “Recovery” in the item. As described above, when the communication device 320 receives the failure signal, the information processing device 360 maintains the failure code “0001” input from the communication device 320, the management number of the elevator 20, and the failure occurrence date and time. The failure history data 377 of the database 370 is stored. Accordingly, all items of the failure history data 377 are updated by storing the current recovery method and the recovery determination result.

  Further, in this remote recovery, the information processing apparatus 360 refers to the recovery diagnosis database 380 and clogs the door sill that is the most frequent failure factor (failure factor 1) when the failure code is “0001” as the recovery command. 2) of “door circuit reset + door open / retry retry” that is a recovery command for executing a recovery operation corresponding to (2)) and “door open / close diagnosis” that is a recovery diagnostic command for executing a recovery diagnostic operation corresponding to the result of this recovery operation. A recovery diagnosis command set A consisting of two is selected and a recovery operation and a recovery diagnosis operation are executed. Accordingly, when the elevator 20 is successfully restored, the number of failure codes “0001” and failure factor 1 (garbage clogs on the door sill) in the restoration diagnosis database 380 is increased by one, and the restoration rate corresponding to the number of successful restorations. To increase. Further, the information processing device 360 increases the number of failure factors 1 of the failure code “0001” in the failure factor-specific data 378 by one.

  On the other hand, the information processing apparatus 360 updates the maintenance database 370 and the restoration diagnosis database 380 as follows when the determination signal indicating that the restoration of the elevator 20 has failed as shown in step S119 of FIG. 5 is input. When a determination signal indicating that the restoration of the elevator 20 has failed as shown in step S119 of FIG. 5 is input, the information processing apparatus 360 displays “remote recovery” in the recovery method item of the failure history data 377, and a recovery determination. Store “failure” in the result item. Further, the number of cases of failure code “0001” and failure factor 1 (garbage on the door sill) in the restoration diagnosis database 380 is left as it is, and the restoration rate is lowered by the amount of restoration failure. Note that if the recovery fails, the number of failure factors 1 of the failure code “0001” in the failure factor-specific data 378 is not changed.

  In the above description, a case has been described in which the information processing apparatus 360 selects the restoration diagnosis instruction set A based on the failure factor having the largest number corresponding to the failure code “0001”. When the information processing device 360 selects the recovery diagnosis command set B based on the recovery rate of the recovery diagnosis command set corresponding to the failure code “0001”, the normal operation is performed instead of the recovery operation of “door high torque opening / closing”. A difference is that a recovery operation of “door opening / closing retry” in which the opening / closing operation of the doors 13 and 26 is performed again by torque is performed. Other operations are the same as when the restoration diagnosis command set A is selected.

  If the remote recovery of the elevator 20 is successful, the number of door cloggings (failure factor 1), which has been the most frequent failure factor in the case of the failure code “0001”, increases. For this reason, when the remote recovery system 100 selects a recovery diagnosis command set based on the most frequent failure factor corresponding to the failure code “0001”, the failure code “0001” is input at the time of the next remote recovery. At this time, the information processing apparatus 360 selects the restoration diagnosis command set A again. When the recovery rate of the recovery diagnosis command set A is higher than the recovery rate of the recovery diagnosis command set B, the information processing apparatus 360 has a recovery rate of a plurality of commands corresponding to the failure code “0001”. Even when the highest command is selected as the return command, the restoration diagnosis command set A is selected.

  On the other hand, when the remote recovery of the elevator 20 fails, the number of failure factors 1 of the failure code “0001” in the failure factor-specific data 378 is not changed, but the recovery rate of the recovery diagnosis command set A is lowered. Thereby, the recovery rate of the recovery diagnosis command set B becomes relatively high. That is, the recovery rate ratio of the recovery diagnosis command set B to the recovery diagnosis command set A is increased. When the restoration rate ratio becomes larger than the number ratio calculated as the ratio of the number of failure factors 1 to the number of failures 2, the information processing apparatus 360 recovers among the plurality of commands corresponding to the failure code “0001”. The command with the highest rate is selected as the return command. For this reason, the information processing apparatus 360 selects the restoration diagnosis command set B having the highest restoration rate when the failure code “0001” is input at the time of the next remote restoration. Further, when the information processing device 360 does not select the restoration diagnosis command set A that has failed to be restored in the previous remote restoration, the failure factor 1 is linked to the failure factor 2 having the largest number corresponding to the failure code “0001”. Restored diagnosis command set B is selected.

  Further, when the information processing apparatus 360 selects the restoration diagnosis command set B having the highest restoration rate among the plurality of instructions corresponding to the failure code “0001” and succeeds in the restoration of the elevator 20, the restoration diagnosis instruction set The recovery rate of B increases. Therefore, in the next remote recovery, the information processing apparatus 360 selects the recovery diagnosis command set B as in the previous time. On the other hand, if the restoration diagnosis command set B fails to restore the elevator 20, the restoration rate of the restoration diagnosis command set B is lowered. When the recovery rate of the recovery diagnosis command set B is lower than the recovery rate of the recovery diagnosis command set A, the information processing device 360 selects the recovery diagnosis command set A. If the information processing device 360 does not select the recovery diagnosis command set B that has failed to recover in the previous remote recovery, the recovery diagnosis with the high recovery rate corresponding to the failure code “0001” next to the recovery diagnosis command set B Select command set A.

  Thus, when the remote recovery is successful, the remote recovery system 100 increases the number of failure factors and the recovery rate of the selected recovery diagnosis command set. In addition, if the remote recovery system 100 fails, the remote recovery system 100 reduces the recovery rate of the selected recovery diagnosis command set without changing the number of failure factors. For this reason, if the remote recovery is successful, there is a high possibility that the recovery diagnosis command set selected in the remote recovery is selected in the next remote recovery. Further, if the remote recovery fails, the possibility that the recovery diagnosis command set selected by the remote recovery is selected at the next remote recovery is reduced. For this reason, as the number of remote restorations increases, the information processing apparatus 360 can select a restoration diagnosis command set having a high possibility of restoration corresponding to the failure code from the restoration diagnosis database 380, and the restoration of the elevator 20 is ensured. Can be improved.

  In the above-described embodiment, the operation of the remote recovery system 100 when the failure code “0001” indicating that the failure is related to the doors 13 and 26 is output from the control panel 210 has been described. Next, a case where a failure code “0002” indicating a failure related to the control circuit is output from the control panel 210 will be described. The description of the same operation as when the failure code “0001” is output is omitted.

  If the failure code is “0002” indicating a failure related to the control circuit, the engineer 350 inspected the site to find out that the cause of the output of the failure code “0002” is defective in the relay attached to the control panel 210. This is a case (failure factor 4), a case where there is a defect in the relay drive circuit that drives the relay (failure factor 5), or another failure factor 6. The failure factor-specific data 378 indicates that when the failure code is “0002”, there are 100 cases where the failure is caused by a failure (failure factor 4), 50 cases where the failure of the relay drive circuit is caused (failure factor 5), etc. The data structure is such that there are 10 cases of failure factor 6 and the data is arranged in descending order. As described above, in the case of recovery by the remote recovery system 100, when the elevator 20 is successfully recovered by the recovery command, the number of failure factors corresponding to the failure code that is the basis of the recovery command is the overall failure factor. It is added to the number of cases.

  As shown in FIG. 7, the recovery diagnosis database 380 is a database in which a failure diagnosis data set 378 is linked to a recovery diagnosis command set and a recovery rate. Hereinafter, the data configuration of the recovery diagnosis database 380 when the failure code is “0002” indicating a failure related to the control circuit will be described. When there is a fault in the relay (Failure factor 4), the restoration diagnosis data is “control circuit reset + low speed up / down operation” as the restoration command in the number data of the failure factor 4 and “each floor operation, high speed” as the restoration diagnosis command. This is a data configuration in which a recovery diagnosis command set D, which is a set of two commands “operation diagnosis”, and a recovery rate a% by a recovery operation based on the recovery diagnosis command are linked. If there is a failure in the relay drive circuit (failure factor 5), the restoration diagnosis data is “control circuit reset + operation between the top and bottom floors” as the restoration command, and the restoration command “ The data structure is obtained by linking a recovery diagnosis command set E, which is a set of two commands, “operation on each floor and high-speed operation diagnosis”, and a recovery rate b% by a recovery operation based on the recovery diagnosis command. Similarly, in the case of the failure factor 6, the recovery diagnosis data has a data structure in which the recovery diagnosis command set F and the recovery rate c% are linked to the number data of the failure factor 6. As described above, the recovery diagnosis database 380 includes the failure code, the failure factor corresponding to the failure code, the number of the failure factors, the recovery diagnosis command set that is a set of the recovery command and the recovery diagnosis, and the recovery rate. It is stored in the database in association. Note that the recovery rate is the highest in b% of the recovery diagnosis command set E.

  When the failure code is “0002”, the information processing device 360 selects the restoration diagnosis instruction set D based on the failure factor having the largest number of cases corresponding to the failure code “0002”. 360 transmits a restoration diagnosis command set D to the control panel 210. After executing the control circuit reset operation, the control panel 210 performs low-speed up and down operations that raise and lower the cage 22 of the elevator 20 at low speed. After that, the control panel 210 performs each floor operation that stops on each floor without opening and closing the doors 13 and 26, high speed operation that operates between a plurality of floors at high speed, operation that stops on each floor, and high speed operation Check for any abnormal driving. When there is no abnormality in each floor operation and high-speed operation, the control panel 210 outputs a determination result of successful restoration of the elevator 20. In addition, when an abnormality is detected in each floor operation or high-speed operation, the control panel 210 outputs a determination result of failure in restoration of the elevator 20. This determination result is input from the control panel 210 to the information processing device 360 via the communication devices 250 and 320. As described above, the information processing apparatus 360 may select failure history data 377, failure factor-specific data 378, recovery diagnosis so that a recovery diagnosis command set having a higher recovery possibility can be selected based on the determination result. The database 380 is updated.

  Further, when the information processing apparatus 360 selects the restoration diagnosis command set E having the highest restoration rate corresponding to the failure code “0002”, the information processing apparatus 360 transmits the restoration diagnosis instruction set E to the control panel 210. After executing the control circuit reset operation, the control panel 210 executes the operation between the lowermost floor and the uppermost floor for moving the basket 22 of the elevator 20 between the lowermost floor and the uppermost floor. Next, the control panel 210 executes each floor operation and high-speed operation described above, performs restoration diagnosis of the elevator 20, and outputs a determination result of whether the restoration of the elevator 20 has succeeded or failed. As described above, the determination result is input from the control panel 210 to the information processing device 360 via the communication devices 250 and 320. The information processing device 360 updates the failure history data 377, the failure factor-specific data 378, and the recovery diagnosis database 380 so that a recovery diagnosis command set having a higher recovery possibility can be selected based on the determination result.

  Next, a case where the failure code is “0003” indicating that the failure is related to the brake will be described.

  In the case where the failure code is 0003 indicating a failure related to the brake, the engineer 350 inspected the site on the spot. As a result, the failure code “0003” is output because the brake circuit of the control panel 210 is abnormal (failure factor 7). Or other failure factor 8 or failure factor 9. Therefore, in the case of the failure code “0003”, the failure factor-specific data 378 includes 100 cases in which the brake circuit abnormality is the cause (failure factor 7), 50 cases in the case of failure factor 8, and 9 cases in the case of other failure factors 9. The data structure is such that there are 10 cases, and the data is arranged in descending order. As described above, in the case of recovery by the remote recovery system 100, when the elevator 20 is successfully recovered by the recovery command, the number of failure factors corresponding to the failure code that is the basis of the recovery command is the overall failure factor. It is added to the number of cases.

  As shown in FIG. 8, the recovery diagnosis database 380 is a database in which a recovery diagnosis command set and a recovery rate are linked to the failure factor-specific data 378. Hereinafter, the data structure of the recovery diagnosis database 380 when the failure code is “0003” indicating a failure related to the brake will be described. When the abnormality of the brake circuit is a factor (failure factor 7), the restoration diagnosis data includes two data, “control circuit reset” as a restoration command and “brake torque diagnosis” as a restoration diagnosis command. The data configuration is such that a recovery diagnosis command set G, which is a set of commands, and a recovery rate d% by a recovery operation based on the recovery diagnosis command are linked. In the case of the failure factor 8 and the failure factor 9, the recovery diagnosis data includes the recovery diagnosis command set H and the recovery rate e%, the recovery diagnosis command set I and the recovery rate f% in the number data of the failure factor 8 and the failure factor 9, respectively. Are linked to each other. As described above, the recovery diagnosis database 380 includes the failure code, the failure factor corresponding to the failure code, the number of the failure factors, the recovery diagnosis command set that is a set of the recovery command and the recovery diagnosis, and the recovery rate. It is stored in the database in association. Note that the recovery rate is highest in e% of the recovery diagnosis command set H.

  Next, the operation of the remote recovery system 100 when the control panel 210 detects a failure related to the brake will be described.

  When the failure code is “0003”, the information processing device 360 selects the restoration diagnosis command set G based on the failure factor having the largest number of cases corresponding to the failure code “0003” in step S106 in FIG. In this case, the information processing device 360 transmits a restoration diagnosis command set G to the control panel 210.

  When the failure code is “0003”, when receiving the restoration diagnosis command set G, the control panel 210 executes a brake torque diagnosis operation in the field confirmation shown in step S109 of FIG. In the brake torque diagnosis operation, the hoisting machine in the driving device 24 is not rotated by a mechanical brake, and a driving force is applied to the hoisting machine to confirm that the hoisting machine does not rotate by the holding force of the brake. Is the action. If there is no abnormality in this operation, the control panel 210 makes an announcement of remote recovery assuming that the site of the elevator 20 can be confirmed in step S109 of FIG. Thereafter, the process proceeds to step S110 in FIG. 5, and the control panel 210 executes a control circuit reset operation.

  Thereafter, the control panel 210 executes a brake torque diagnosis operation. When there is no rotation of the hoist due to this operation, the control panel 210 outputs a determination result indicating that the elevator 20 has been successfully restored. Further, when the hoisting machine rotates, the control panel 210 outputs a determination result of failure in restoration of the elevator 20. This determination result is input from the control panel 210 to the information processing device 360 via the communication devices 250 and 320. The information processing device 360 updates the failure history data 377, the failure factor-specific data 378, and the recovery diagnosis database 380 so that a recovery diagnosis command set having a high recovery possibility can be selected based on the determination result.

  Further, as described above, the information processing apparatus 360 selects the restoration diagnosis command set H having the highest restoration rate corresponding to the failure code “0003” and causes the control panel 210 to execute the restoration operation and the restoration diagnosis operation. You can also.

  Note that if there is an abnormality in the brake torque diagnosis operation, the control panel 210 determines that remote recovery cannot be started, and notifies the remote monitoring center 310 that remote recovery is not possible without executing the remote recovery operation.

  As described above, when various failures occur in the elevator 20, the remote recovery system 100 performs a recovery operation and recovery diagnosis on the elevator 20 according to a command from the remote recovery device 300 disposed at a location away from the elevator 20. The operation can be executed to restore the elevator 20. For this reason, when failure occurs in the elevator 20, the elevator 20 can be restored in a short time without dispatching the technician 350 to the site, and the operation service of the elevator 20 can be improved.

  In addition, the remote recovery system 100 can select a failure history data 377, failure factor-specific data 378, so that a recovery diagnosis command set having a high possibility of recovery can be selected in the next remote recovery based on the recovery determination result. The recovery diagnosis database 380 is updated. Therefore, as the number of remote restorations increases, the information processing apparatus 360 can select a more appropriate restoration diagnosis command set corresponding to the failure code from the restoration diagnosis database 380. Thereby, the restoration of the elevator 20 can be reliably performed, and the time required for the restoration can be shortened to improve the operation service of the elevator 20.

<Remote diagnosis processing>
As shown in FIG. 2, the information processing apparatus 360 is divided into a functional block that executes remote recovery processing and a functional block that executes remote diagnosis. The information processing device 360 includes a similar elevator extraction unit 400, a diagnostic operation command unit 402, a maintenance / inspection necessity determination unit 404, a threshold change unit 406, a diagnostic operation schedule setting unit 408, a temporary abnormality as functional blocks of the latter (remote diagnosis). A setting unit 410 and a diagnostic operation item database 412 are provided. In remote diagnosis, various data in the maintenance database 370 are used. From such a viewpoint, the remote recovery apparatus 300 according to the present embodiment also has a function as a remote monitoring apparatus.

  9 and 10 exemplify flowcharts of remote diagnosis processing by the remote recovery device 300 (remote monitoring device). Steps S101 to S104 have the same contents as those in FIG. Since the steps of FIG. 5 partially overlap, it can be said that the remote diagnosis processing according to the present embodiment is a processing flow branched from the remote recovery processing.

  In the following description, an example in which the elevator 20 that is the source of the failure signal is the elevator 20A and the similar elevator is the elevator 20B will be described.

  If the failure content of the elevator 20 (20A) is not remotely recoverable in step S104, the engineer (security officer) needs to perform a safety check that rushes to the elevator 20A for recovery, and the process proceeds to step S1002. Note that a safety inspection based on a failure is hereinafter referred to as an emergency safety inspection as appropriate, as opposed to a normal safety inspection such as a legal inspection.

  When the failure content of the elevator 20 is remotely recoverable, the diagnostic operation command unit 402 of the information processing device 360 receives the failure control signal from the elevator control device 200A (control panel 210A) of the elevator 20A. Wait for the recovery judgment result (S113 in FIG. 5) of the remote restoration operation. When the restoration determination result is transmitted from the elevator control device 200A to the information processing device 360 via the communication devices 250A and 320, the diagnostic operation command unit 402 of the information processing device 360 determines whether the restoration determination result is a restoration failure. Determine (S1000).

  If the recovery judgment result is a successful recovery, the emergency diagnosis check is not required, so the remote diagnosis process flow ends (FIG. 10). On the other hand, when the recovery determination result is a recovery failure, an emergency safety check is required for the recovery of the elevator 20A, and the process proceeds to step S1002.

  In step S1002, an elevator 20A that is not remotely recoverable or fails in remote recovery, that is, an elevator 20A that is similar to the elevator 20A that requires maintenance inspection, in other words, that is predicted to have a future failure (similar elevator) is extracted. As described later, by extracting a similar elevator and performing a remote diagnosis, it is determined whether or not an emergency security check is required for the similar elevator.

  When extracting similar elevators, the similar elevator extraction unit 400 of the information processing apparatus 360 refers to data stored in the maintenance database 370. Specifically, the similar elevator extraction unit 400 extracts similar elevators based on the elevator specification data 371 (specification storage unit) in the maintenance database 370.

  As shown in FIG. 3, various specification items are stored in the elevator specification data 371 (specification storage unit). The similar elevator extraction unit 400 extracts the elevator 20 that has at least one of the specification items in common with the elevator 20A that is the source of the failure signal, as a similar elevator.

  For example, among the specification items of the elevator specification data 371 (specification storage unit) illustrated in FIG. 3, the elevator management number and the manufacturing number are unique to the elevator, and thus are not basically shared between the elevators 20. There is a possibility that the six items of the remaining model, manufacturing date, installation building name, installation building use, installation environment, and number of times of rope bending are common among the elevators 20. The similar elevator extraction unit 400 calls the specification data of the elevator 20A that is the source of the failure signal from the elevator specification data 371, and extracts the elevator 20 that has at least one common specification item as a similar elevator.

  Further, in addition to the elevator specification data 371 (specification storage unit), other data in the maintenance database 370, for example, the elevator 20 common to each item of the operation history data 379 and the failure history data 377 may be extracted as a similar elevator. .

  Here, the greater the number of items common to the items of the elevator 20A, the higher the execution order of remote diagnosis described later. Further, a weighted score may be given to each specification item, and the execution order of remote diagnosis may be determined based on the total score. This score may be changed according to the failure code.

  For example, when the failure code indicates the control panel 210A, that is, when the failed device is the control panel 210A, even if the number of times of rope bending is common between the elevator 20A and the other elevator 20, the failed device (control panel 210A). Therefore, the weighting of the score is relatively low because it is not an important common matter. On the other hand, when the failure code indicates the wire 23A, the weight of the number of times of rope bending is relatively high. Thus, the storage unit (not shown) of the information processing apparatus 360 may store the score of each item in the maintenance database in association with the failure code.

  When the similar elevator is extracted, the temporary abnormality setting unit 410 refers to the diagnostic operation item database 412 and sets the temporary abnormality flag of the elevator management number extracted as the similar elevator in step S1002 to “valid” (S1004). .

  FIG. 11 shows remote diagnosis setting data for the elevator management number 123456 among the data stored in the diagnostic operation item database 412. In this database, diagnosis items at the time of remote diagnosis, specific diagnosis contents, and determination thresholds are set.

  The diagnosis item is determined according to, for example, a customer request for delivering the elevator 20. The diagnosis contents and the determination threshold are determined by the specification of the elevator 20 and the date of manufacture. The determination threshold is divided into three categories of normal, modulation, and abnormality, and these categories are divided by the determination threshold.

  In the diagnostic operation item database 412, the temporary abnormality flag can be set to be valid / invalid. As described above, the provisional abnormality setting unit 410 effectively sets the provisional abnormality flag for similar elevators.

  In the diagnostic operation item database 412, the scheduled execution date and time of the remote diagnostic operation is set in advance. This set date and time is changed by the diagnostic operation schedule setting unit 408 when set to a similar elevator. For example, the scheduled execution date and time of the remote diagnosis operation is changed immediately after being extracted as a similar elevator in step S1002.

  The threshold value changing unit 406 refers to the diagnostic operation item database 412 and changes the determination threshold value of the elevator management number (similar elevator) in which the temporary abnormality flag is set to be valid (S1006). Specifically, as illustrated in FIG. 12, the determination threshold value for dividing the normal value, the modulation value, and the abnormal value is raised to the normal value side. In other words, the threshold value is changed so that the judgment becomes stricter.

  As described above, similar elevators have specifications and equipment similar to the failed equipment, and there is a possibility of failure in the near future even if it is currently normal or modulated. Therefore, in remote diagnosis for similar elevators, the determination threshold for diagnosis is made strict, and equipment is replaced if there is any sign of failure.

  The diagnosis operation command unit 402 performs remote diagnosis operation to the control panel 210 (for example, 210B) of the similar elevator via the communication devices 320 and 250 (250B) when the execution date and time of the remote diagnosis operation is changed at the current time. An execution command is transmitted (S1008). In addition to the remote diagnostic operation execution command, the remote diagnostic operation diagnostic items, diagnostic contents, and determination threshold are transmitted to the control panel 210B. At this time, the determination threshold value changed by the threshold value changing unit 406 is used as the determination threshold value for the diagnostic operation. Further, the diagnosis item, the diagnosis content, and the determination threshold may be only those related to the failure code transmitted in step S102.

  The control panel 210B executes a diagnostic operation in response to a remote diagnostic operation execution command and a diagnostic item transmitted along with the command (S1010). Prior to the diagnostic driving, an announcement that the user is leaving the landing may be made on the assumption that there are passengers in the vicinity. Alternatively, the diagnostic operation may be executed after guiding passengers in the car to the nearest floor and leaving the car.

  Each diagnostic item of the diagnostic operation is determined by the control panel 210B. When the detected value is included in the normal region in all the diagnostic items, the control panel 210B and the communication device 250B transmit a diagnostic result indicating that the diagnostic value is normal (S1012). The communication device 320 receives this and sends it to the information processing device 360.

  On the other hand, if the detected value is included in the abnormal region in any of the diagnostic operation results in step S1010, the control panel 210B and the communication device 250B indicate that the abnormality is detected, the device determined to be abnormal, and its detected value ( (Abnormal value) is transmitted (S1012). The communication device 320 receives this and sends it to the information processing device 360.

  The maintenance / inspection necessity determination unit 404 acquires the diagnosis result transmitted from the control panel 210B and determines whether or not the result is normal (S1014 in FIG. 10). If it is normal, the maintenance / inspection necessity determination unit 404 determines that the emergency maintenance / inspection is unnecessary (S1016). In response, the temporary abnormality setting unit 410 sets the temporary abnormality flag from valid to invalid (S1018). In addition, the information processing apparatus 360 transmits a determination result (normal) to the remote monitoring center 310 (S1020). The contents and results of the diagnostic operation at this time are stored in the remote inspection history data 374. Further, the information processing device 360 sends a command to the control panel 210B to switch the operation of the similar elevator 20B from the diagnostic operation to the normal operation (S1022).

  Next, the diagnostic operation schedule setting unit 408 sets the date and time of the next remote diagnostic operation (S1024). For example, the date and time of the next remote diagnosis operation is set for the similar elevator 20B at an interval (for example, once a week) that is shorter than a predetermined regular interval (for example, once a month). Thereby, it becomes possible to monitor the change in the state of the equipment of the similar elevator 20B, in which the failure is reported in the other elevator 20A, at shorter time intervals.

  On the other hand, when the diagnosis result transmitted from the control panel 210B in step S1014 is an abnormality determination, that is, when the detected value is included in the abnormality region in any of the diagnostic operation results, the maintenance / inspection necessity determination unit 404. Determines that an emergency check is necessary (S1026).

  In response to the determination, the information processing apparatus 360 transmits a determination result (for example, abnormality determination, abnormality determination target device, and abnormal value) to the remote monitoring center 310 (S1028). The contents and results of the diagnostic operation at this time are stored in the remote inspection history data 374.

  Furthermore, the supervisor 334 of the remote monitoring center 310 instructs the operation stop of the elevator 20B and the announcement operation via the communication devices 320 and 250B and the control panel 210B (S1030). Then, the supervisor 334 instructs the service center 340 in the vicinity of the building 10B to dispatch the engineer 350 (security worker) to the building 10B by the telephone 333, and executes an emergency security check (S1032).

  In addition, when the remote monitoring center 310 receives the determination result (abnormal) in step S1028, the apparatus determined to be abnormal is also received. From this, the supervisor 334 of the remote monitoring center 310 may place an order for replacement parts, that is, replacement parts for the failed equipment, at the material center (not shown) or the like in accordance with the instruction to execute the emergency security inspection. In addition, the supervisor 334 registers the replacement work of the failed device in the inspection item of the emergency maintenance inspection.
