Description

  The present invention relates to a system for performing remote recovery when a failure occurs in an elevator.

  Conventionally connected to the control panel that controls the drive of the elevator, and when the elevator breaks down, a communication terminal that transmits a failure signal including an error code, and a failure signal transmitted from the communication terminal is received and corresponds to the error code A monitoring center that searches for failure history data to be transmitted and sends it to the mobile terminal held by maintenance personnel, analyzes the error code received by the mobile terminal owned by the maintenance personnel from the monitoring center, and displays it as recovery contents for each cause of failure An elevator failure recovery support system is known (see, for example, Patent Document 1). The failure recovery support system described in Patent Document 1 allows the maintenance staff to know the details of the elevator failure before arriving at the failed elevator, and can proceed with the recovery work immediately after arrival at the building. It enables recovery work to be performed efficiently.

  Moreover, an abnormality may occur in the elevator system due to temporary factors such as noise, and the elevator operation may be stopped. However, when the occurrence of an abnormality is due to a temporary factor such as noise, the abnormality factor may disappear after the elevator is stopped, and the abnormality of the elevator may not be detected. Then, when abnormality is detected in the elevator system, a method of stopping the operation of the elevator and then restarting the operation of the elevator when no abnormality is detected is proposed (for example, see Patent Document 2). ).

  However, in the system described in Patent Document 1, when an elevator breaks down, it is necessary for a maintenance person or engineer to go to the site to restore the elevator, so it takes time to restore the elevator operation service. There is a problem that will decrease.

  In addition, the method described in Patent Document 2 stops the operation of the elevator due to an abnormality actually occurring, for example, when the door sill is clogged with garbage and the door cannot be opened and closed smoothly. If the abnormality continues to be detected after the elevator operation is stopped, the elevator operation cannot be resumed, and it is necessary to perform recovery by an engineer. Therefore, although the method described in Patent Document 2 can resume the operation of the elevator without performing restoration work by an engineer when the operation of the elevator is stopped due to temporary factors such as noise, If any abnormality actually occurs, restoration by an engineer is required, leading to a decrease in elevator service. On the other hand, in recent years, the demand for improving elevator service has been increasing.

The use of the installed building is, for example, an office, a general residence, a restaurant, a school, and the like.

  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, confirmation 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 performed by the control panel 210 of the elevator 20 according to a preset schedule such as once a month, for example. 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. The remote inspection may be performed according to an instruction from the remote monitoring center 310.

  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. . 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 a management number of the elevator 20, a repair work date, a repair work item, and a repair work result. 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.

Items such as “Necessary” are entered.

  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.

  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. 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 and the “door opening / closing retry” command as the restoration diagnosis command. This is a data structure in which a recovery diagnosis command set B, which is a set of two “diagnosis” commands, and a recovery rate y% of a recovery operation by this recovery command are linked. 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 and 5 to 7. 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, the remote recovery operation when a failure code “0002” 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. Upon 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 or not 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. If the elevator 20 is a model that cannot perform the restoration operation and the restoration diagnosis operation, the information processing apparatus 360 determines NO in step S104 of FIG. Then, the information processing apparatus 360 outputs a remote recovery impossible notification to the remote monitoring center 310 as shown in step S127 of FIGS.

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 no 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 a similar 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. Then, as shown in step S127 of FIGS. 2 and 7, the information processing device 360 outputs a notification that remote recovery is impossible 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 S127 of FIGS.

  The notification that remote recovery is not possible and 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 a result, the monitor 334 of the remote monitoring center 310 is notified that the elevator 20 cannot be remotely recovered. After confirming this display, the supervisor 334 causes the elevator 20 to stop operating and announce as shown in step S128 of FIG. 2 and FIG. 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 as shown in Step S129 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 a 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.

  A case will be described in which the information processing device 360 selects a command corresponding to the failure factor having the largest number of failure factors among the plurality of failure factors corresponding to the failure code “0001” as the 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.

  When the restoration command and the restoration diagnosis command are input, the control panel 210 performs a confirmation operation as to whether or not the elevator 20 is ready to start remote restoration as shown in step S109 of FIG.

  The control panel 210 confirms whether there are passengers in the basket 22 based on outputs from the weight sensor of the basket 22, the camera in the basket 22, the person sensor, and the like. Also, the open / closed state of the doors 13 and 26 is confirmed from the output of the camera, the door open / close sensor, etc. in the cage 22. Furthermore, the control panel 210 confirms the presence or absence of a power failure.

  If there is no passenger in the basket 22, the doors 13 and 26 are fully closed, and the power failure state does not occur, the control panel 210 determines YES in step S109 in FIG. 5, and step S110 in FIG. Proceed to Then, in step S110, the control panel 210 makes an announcement such as “Start remote recovery from now on. The door of the elevator opens and closes” from the speaker of the communication device installed in the basket 22.

  If there is a passenger in the car 22, the doors 13 and 26 are not fully closed, or if the power is in a power failure state, the control panel 210 determines NO in step S109 in FIG. 5, and step S125 in FIG. Go to, and perform the following preparatory actions.

  First, the control panel 210 confirms that the floor 27 of the cage 22 is substantially at the same height as the floor 12. After that, the control panel 210 opens the doors 13 and 26 and performs an operation such as “announcement of remote recovery. Please get off the elevator.” To lower the passenger from the cage 22. Alternatively, the control panel 210 performs an operation of opening the doors 13 and 26 and lowering the passenger from the car 22 while making an announcement such as “Start remote recovery. Get off the elevator.” When the passenger gets out of the cage 22 by such an operation, the control panel 210 fully closes the doors 13 and 26 in the open state. Thereafter, the process proceeds to step S126 of FIG. 7, and there is no passenger in the cage 22, the doors 13 and 26 are fully closed, or the floor 27 of the cage 22 is the floor in the same manner as described above. 12 is almost the same height as 12 or it is not in a power outage state. When there is no passenger in the car 22, the doors 13 and 26 are fully closed, the floor 27 of the car 22 is substantially the same height as the floor 12, and the control panel 210 is not in a power failure state, FIG. In step S126, the determination is YES. Then, the process proceeds to step S110 in FIG. 5, and the control panel 210 announces from the speaker of the communication device installed in the basket 22 “Starting remote recovery from now on. The elevator door will open and close.” Do.

  Further, when it is confirmed in step S109 in FIG. 5 that the control panel 210 is in a power failure state and the elevator 20 is operating with an emergency battery, the control panel 210 waits until power is restored, and when power is restored, the step in FIG. Proceed to S125. In step S125, the control panel 210 performs the same preparation operation as described above, and proceeds to step S126 in FIG. If it is determined YES in step S126 of FIG. 7, control panel 210 proceeds to step S110 of FIG. 5 and makes a remote recovery announcement.

  On the other hand, if the control panel 210 determines NO in step S126 of FIG. 7 after the preparation operation shown in step S125 of FIG. 7, the control panel 210 proceeds to step S127 of FIG. In step S127, the control panel 210 outputs a notification that remote recovery is not possible to the remote monitoring center 310.

  The notification that remote recovery is not possible and 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 a result, the monitor 334 of the remote monitoring center 310 is notified that the elevator 20 cannot be remotely recovered. When the monitor 334 confirms this display, the supervisor 334 performs an instruction to stop the operation of the elevator 20 and an announcement operation as shown in step S128 of FIGS. Further, the supervisor 334 instructs the service center 340 in the vicinity of the building 10 to dispatch the engineer 350 to the building 10 as shown in step S129 of FIG. 2 and FIG.

  When the control panel 210 determines YES in step S109 in FIG. 5 or step S126 in FIG. 7 and proceeds to step 110 in FIG. 5 to make an announcement, it proceeds to step S111 in FIG. To do. 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 command resets a state in which the door circuit cannot open or close the door 26 or the door 13 and detects an open (or closed) state or a half-open (or half-closed) state, and opens or closes the door 13 or the door 26. It is a command that makes it possible. 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 S112 in FIG. 5, the control panel 210 restores the garbage stuck in the thresholds of the doors 13 and 26 to confirm 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 doors 13 and 26 by lowering the torque of the drive motor by about 20% than usual, 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 S113 of FIG. 6, the control panel 210 proceeds to step S114 of FIGS. In step S114, 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 S115 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 S116 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, the operation of the elevator 20 is resumed and an announcement operation is performed as shown in step S117 of FIG. Further, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in Step S118 and Step S119 of FIG.

  On the other hand, if the result of the recovery diagnosis operation is NO in step S113 of FIG. 6, control panel 210 proceeds to step S120 of FIG. In step S120, 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 S <b> 121 of FIG. 6, and the determination result is input to the information processing device 360. Further, as shown in step S122 of FIG. 6, the determination result is notified from the information processing apparatus 360 to the remote monitoring center 310, and the result is displayed on the display 331 of the remote monitoring center 310. When the monitor 334 confirms the display, the supervisor 334 performs an instruction to stop the operation of the elevator 20 and an announcement operation as shown in step S123 of FIG. Further, 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 S124 of FIGS. Further, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in Step S118 and Step S119 of FIG.

  When the determination signal that the elevator 20 has been restored as shown in step S114 of FIG. 6 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 S114 of FIG. 6 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 S120 of FIG. 6 is input. When the determination signal indicating that the restoration of the elevator 20 has failed as shown in step S120 of FIG. 6 is input, the information processing apparatus 360 sets “remote restoration” as the restoration method item of the failure history data 377, and the restoration judgment. 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 recovery command, the recovery 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 recovery diagnosis command set B is selected 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.

  The case where the failure code is “0001” indicating that the failure is related to the doors 13 and 26 has been described. Next, a case where the failure code is “0002” indicating that the failure is related to the brake will be described. The description of the same part as the failure code “0001” is omitted.

  When the failure code is 0002 indicating a failure related to the brake, the engineer 350 checked the site, and as a result, the failure code “0002” was output due to an abnormality in the brake circuit of the control panel 210 (failure factor 4). Or other failure factor 5 or failure factor 6. Therefore, in the case of the failure code “0002”, the failure factor-specific data 378 is 100 cases when the brake circuit abnormality is the cause (failure factor 4), 50 cases of the failure factor 5 and other failure factors 6 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 configuration of the recovery diagnosis database 380 when the failure code is “0002” indicating a failure related to the brake will be described. When the abnormality of the brake circuit is a factor (failure factor 4), 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 a% by a recovery operation based on the recovery diagnosis command are linked. In the case of the failure factor 5 and the failure factor 6, the restoration diagnosis data includes the restoration diagnosis command set H and the restoration rate b%, the restoration diagnosis command set I and the restoration rate c% in the number data of the failure factor 5 and the failure factor 6, 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. The recovery rate is highest in b% 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 “0002”, 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 “0002” in step S106 of 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 “0002”, upon receiving this restoration diagnosis command set G, the control panel 210 confirms whether the elevator 20 shown in step S109 of FIG. In addition to the confirmation items in the case of, brake torque diagnosis operation is executed. 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. As in the case where there is no abnormality in this operation and the failure code is “0001”, when there is no passenger in the cage 22 and the doors 13 and 26 are in a fully closed state and not in a power failure state, control is performed. The board 210 determines YES in step S109 of FIG. 5 and proceeds to step S110 of FIG. In step S110, the control panel 210 makes a remote recovery announcement, and then proceeds to step S111 in FIG. In step S111, the control panel 210 executes a control circuit reset operation.

  Thereafter, the control panel 210 executes a brake torque diagnosis operation in step S112. 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, a determination result indicating failure in restoration of the elevator 20 is output. 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.

  The control panel 210 determines that the elevator 20 can only run at a low speed when the hoisting machine slightly moves in the rotational direction in the brake torque diagnosis operation in step S112, and the elevator 20 is partially restored. The determination result that has been successfully obtained may be output. In this case, the control panel 210 indicates that the elevator 20 is in a state where it can be operated with a limited function such as high-speed running or the like, next to or above the display device in the basket 22 or the door 13 on each floor. It displays on a display device and notifies the user of the elevator 20. The determination result of successful partial restoration 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 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 “0002” and causes the control panel 210 to execute the restoration operation and the restoration diagnosis operation. You can also.

  Further, the control panel 210 may be configured as shown in FIG. 5 when there is an abnormality in the brake torque diagnosis operation, or when there are passengers in the basket 22, the doors 13 and 26 are not fully closed, or a power failure occurs. In step S109, NO is determined. Then, the process proceeds to step S127 in FIG. 7, and the control panel 210 notifies the remote monitoring center 310 that remote recovery is impossible.

  As described above, the remote recovery system 100 is not a temporary factor such as noise, and even if an abnormality actually occurs, a command from the remote recovery device 300 arranged at a location away from the elevator 20 is used. Thus, the elevator 20 can be restored by executing the restoration operation and the restoration diagnosis operation. This makes it possible to restore the elevator 20 in a short time without dispatching the technician 350 to the site when a failure occurs in the elevator 20 even if some abnormality actually occurs rather than a temporary factor such as noise. be able to. Therefore, 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. As a result, 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 further reliably performed. Therefore, the time required for restoration can be shortened and the operation service of the elevator 20 can be improved.

  Further, the remote recovery system 100 can restart the operation service by restricting some functions of the elevator 20 when the elevator 20 is partially restored and can operate with some functions restricted. Therefore, the operation service of the elevator 20 can be improved by shortening the period during which the operation service of the elevator 20 is stopped.
