  The elevator specification data 371 has a data structure for storing the management number, model, manufacturing date, manufacturing number, name of the installed building, and usage data of the installed building of the elevator 20. 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, 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, and adjustment 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. 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.

  The failure history data 377 has a data structure for storing the management number, failure occurrence date / time, failure code, elevator status code, recovery method, and recovery determination result of the elevator 20. 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. The elevator status code is a code composed of terms indicating the status of the elevator 20 that is output from the control panel 210 together with the failure code when a failure occurs in the elevator 20. Examples of the elevator status code include “door cannot be opened” and “door cannot be closed”. One elevator status code may be output together with one failure code, or a plurality of elevator status codes may be output together with one failure code. 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 remote recovery, 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, the item “recovery determination result” is input as “failure” when the elevator 20 fails to recover.

  As shown in FIG. 4, the failure factor-specific data 378 stores the number of times the elevator state code is received when a certain failure code and a certain elevator state code are output from the control panel 210. Further, the failure factor-specific data 378 is recovered by the remote recovery system 100 according to the failure code corresponding to the result of the inspection and inspection by the engineer 350 sent to the site, and the number of failure factors corresponding to the elevator status code. In this case, the total number of failure codes and the number of failure factors corresponding to the elevator status code is stored.

  For example, a case will be described in which the failure code is 0001 indicating a failure relating to the doors 13 and 26 and the elevator status code “Door not open” is received A times. As a result of an inspection by the engineer 350 on the spot, the cause of the output of the elevator status code of the failure code “0001” and “door cannot be opened” is that the door sill is clogged (failure factor 1), or the door opening / closing device It may be a contact failure of the switch (failure factor 2) or other failure factor 3. Therefore, the failure factor-specific data 378 includes 100 cases of door clogging factors (failure factor 1) when the failure code “0001” and the elevator status code “door cannot be opened” are output, the door opening and closing device The data structure is such that 50 cases are caused by poor contact of the switch (failure factor 2) and 10 cases are caused by other failure factors 3, and the data is arranged in descending order. . In the case of restoration by the remote restoration system 100, when the elevator 20 is successfully restored by the restoration command, the number of failure factors corresponding to the restoration code and the elevator status code becomes the total number of failure factors. Added.

  Similarly, when the failure code is 0001 indicating a failure relating to the doors 13 and 26 and the elevator status code “Door cannot be closed” is received B times, the elevator status codes of the failure codes “0001” and “Door cannot be closed” are similarly applied. The output factor may be a clogging of the door sill (failure factor 1), a contact failure of the door opening / closing device switch (failure factor 2), or another failure factor 3. Therefore, the failure factor-specific data 378 includes 100 cases of door clogging factors (failure factor 1) when a failure code “0001” and an elevator status code “door cannot be closed” are output, a door opening / closing device The data structure is such that 50 cases are caused by poor contact of the switch (failure factor 2) and 10 cases are caused by other failure factors 3, and the data is arranged in descending order. .

  The same applies to the case where two elevator status codes “door cannot be opened” and “door cannot be closed” are output together with the failure code “0001”.

  As shown in FIGS. 5 and 6, the recovery diagnosis database 380 is a set of a recovery command and a recovery diagnosis command in descending order of the number of failure factors corresponding to the failure code and elevator status code in the failure factor-specific data 378. A diagnosis command set and a restoration rate (%) that is a rate at which the failure of the elevator 20 is restored by executing the restoration command are stored. 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, as shown in FIG. 5, 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 and the elevator status code is “door cannot be opened” will be described. If the door sill is clogged (Failure factor 1), the restoration diagnosis data will be “Reset door circuit + door high torque” as the restoration command in the case data of failure factor 1 corresponding to the elevator status code “Door not open”. The data structure links the restoration diagnosis command set A, which is a set of two commands, “opening / closing” and “door opening / closing diagnosis” as a restoration diagnosis command, and the restoration rate a% by the restoration operation by this restoration command. . When the contact failure of the switch of the door opening / closing device is the cause (failure factor 2), the restoration diagnosis data is “door circuit reset + Data structure that links recovery diagnosis command set B, which is a set of two commands of “door opening / retry retry” and “door opening / closing diagnosis” as a recovery diagnosis command, and a recovery rate b% of the recovery operation by this recovery command. Yes. Similarly, in the case of failure factor 3, the recovery diagnosis data is data obtained by linking the recovery diagnosis command set C and the recovery rate c% to the number of failure factors 3 corresponding to the elevator status code “cannot open the door”. It has a configuration. As described above, the recovery diagnosis database 380 is a set of a failure code, an elevator status code, a failure factor corresponding to the failure code and the elevator status code, the number of the failure factors, a recovery command and a recovery diagnosis. The diagnosis command set and the recovery rate are stored in the database in association with each other. In this embodiment, the recovery rate b% is a larger value than the recovery rates a% and c%, 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.

  Next, as shown in FIG. 6, 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 and the elevator status code is “door cannot be closed” will be described. If the door sill is clogged (failure factor 1), the restoration diagnosis data will be “door circuit reset + door high torque” as the restoration command in the case data of failure factor 1 corresponding to the elevator status code “cannot close the door”. The data structure links the restoration diagnosis command set A, which is a set of two commands, “opening / closing” and “door opening / closing diagnosis” as the restoration diagnosis command, and the restoration rate d% by the restoration operation by this restoration command. . If the contact failure of the switch of the door opening / closing device is the cause (failure factor 2), the restoration diagnosis data will be “door circuit reset + Data structure that links recovery diagnosis command set B, which is a set of two commands of “door opening / closing retry” and “door opening / closing diagnosis” as a recovery diagnosis command, and recovery rate e% of the recovery operation by this recovery command. Yes. Similarly, in the case of failure factor 3, the recovery diagnosis data is data obtained by linking the recovery diagnosis command set C and the recovery rate f% to the number of failures of failure factor 3 corresponding to the elevator status code “cannot close the door”. It has a configuration. As described above, the recovery diagnosis database 380 is a set of a failure code, an elevator status code, a failure factor corresponding to the failure code and the elevator status code, the number of the failure factors, a recovery command and a recovery diagnosis. The diagnosis command set and the recovery rate are stored in the database in association with each other. In the present embodiment, the recovery rate e% is a numerical value larger than the recovery rates d% and f%, 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, 7, and 8. In the following explanation, first, when the failure code signal “0001” regarding the doors 13 and 26 and the elevator status code “Door not open” are transmitted, the remote recovery operation, and the failure code signals “0001” and “Door open” The remote recovery operation when two elevator status codes of “impossible” and “door cannot be closed” are transmitted will be described. Next, the remote recovery operation when the failure code “0002” and the “unstartable” elevator status code related to the control circuit incorporated in the control panel 210 are transmitted, and the failure codes “0002” and “startup” The remote recovery operation when two elevator status codes of “impossible” and “inter-floor stop” are 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.

  First, the remote recovery operation when the failure code signal “0001” and the elevator status code “door cannot be opened” are transmitted will be described. 2 and 7, the control panel 210 of the elevator 20 outputs the failure code “0001” regarding the doors 13 and 26 of the elevator 20 and the elevator status code “door cannot be opened” to the communication device 250. To do. 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” and the elevator status code “door cannot be opened” are input from the control panel 210, the communication device 250 receives the failure code “0001” and the “door” as shown in step S102 of FIGS. A failure signal including the elevator status code “not open”, the management number of the elevator 20, and the failure occurrence date and time is transmitted to the communication network 30. 2 and 7, when 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, the failure code “0001” included in the failure signal is received. ”And“ Door Unopenable ”elevator status code, elevator 20 management number, and failure date and time are output to the information processing device 360. The information processing device 360 stores the entered failure code “0001”, “door not open” elevator status code, elevator 20 management number, and failure occurrence date and 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 FIG. 2 and FIG. 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, and the elevator 20 is a remote recovery device. It is confirmed whether the specification is such that the recovery operation and the recovery diagnosis operation can be performed by the recovery command and the recovery diagnosis command from 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.

It is determined to be good, and NO is determined in step S104 of FIG. 2 and 7, 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 determines whether or not the building 10 is a building with many false signal transmissions from the elevator specification data 371 and the failure history data 377 using the management number of the elevator 20. When it is determined that the building has many false signal transmissions, the information processing apparatus 360 has a high possibility of erroneous signal transmission. It is determined that dispatching is better, and NO is determined in step S104 of FIG. 2 and 7, the information processing apparatus 360 outputs a notification that remote recovery is not possible to the remote monitoring center 310.

  As shown in FIG. 2, the notification indicating that remote recovery is not possible that 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. After confirming this display, the supervisor 334 causes the elevator 20 to stop operating and announces as shown in step S125 of FIGS. 2 and 8. Further, the supervisor 334 instructs the service center 340 in the vicinity of the building 10 to dispatch the technician 350 to the building 10 by the telephone 333 as shown in step S126 of FIGS.

  If it is determined in step S104 in FIG. 7 that the elevator 20 cannot be remotely restored, the information processing apparatus 360, in step S103, inputs the failure code “0001”, the elevator status code “door cannot be opened”, and the elevator 20 Are stored in the failure history data 377 of the maintenance database 370. Then, the remote recovery operation is terminated 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. 7, the information processing apparatus 360, as shown in FIG. 2, the inspection history data 372, maintenance work history data 373, remote inspection history data 374, modulation history data 375, repair work history data 376. The following (g) to (n) are confirmed with reference to the failure history data 377.

Outputs a signal notifying the start of recovery. 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 device 360 notifies the remote monitoring center 310 of the start of remote recovery in step S105, the information processing device 360 proceeds to step S106 shown in FIG. 7, and the recovery command corresponding to the elevator status code of the failure code “0001” and “door cannot be opened” And restoration diagnosis command. As described above with reference to FIG. 5 and FIG. 6, 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 “0001” and the elevator status code is “door cannot be opened” will be briefly described again. If the door sill is clogged (Failure factor 1), the restoration diagnosis data will be “door circuit reset + door” as the restoration command in the case data of failure factor 1 corresponding to the elevator status code “Door not open”. A data structure that links a recovery diagnosis command set A, which is a set of two commands, “high torque opening / closing” and “door opening / closing diagnosis” as a recovery diagnosis command, and a recovery rate a% by a recovery operation by this recovery command. ing. When the contact failure of the switch of the door opening / closing device is the factor (failure factor 2), the restoration diagnosis data is “door circuit” as the restoration command to the number data of the failure factor 2 corresponding to the elevator status code “Door not open”. A data configuration in which a recovery diagnosis command set B, which is a set of two commands of “reset + door opening / retry retry” and “door opening / closing diagnosis” as a recovery diagnosis command, and a recovery rate b% of the recovery operation by this recovery command are linked, It has become. Similarly, in the case of failure factor 3, the recovery diagnosis data is data obtained by linking the recovery diagnosis command set C and the recovery rate c% to the number of failure factors 3 corresponding to the elevator status code “cannot open the door”. It has a configuration. Further, as described above, the recovery rate b% is larger than the recovery rates a% and c%, 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 apparatus 360 may select, as a restoration command, a command corresponding to the failure factor having the largest number of failure factors among the plurality of failure factors corresponding to the elevator status codes of the failure code “0001” and “door open impossible”. . In addition, the information processing apparatus 360 may select a command having the highest recovery rate among a plurality of commands corresponding to the elevator status codes of the failure code “0001” and “door opening impossible” as the 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, when the information processing device 360 selects, as a restoration command, a command corresponding to the failure factor having the largest number of failure factors among the plurality of failure factors corresponding to the elevator status codes of the failure code “0001” and “door opening impossible” Will be described. The information processing apparatus 360 refers to the recovery diagnosis database 380 shown in FIG. 5 and determines the door sill that is the most frequent failure factor when the failure code is “0001” and the elevator status code is “door cannot be opened”. “Door circuit reset + door open / retry retry”, which is a recovery command for executing a recovery operation corresponding to garbage clogging (fault factor 1), and a recovery diagnostic command for executing a recovery diagnosis operation corresponding to the result of this recovery operation “ A restoration diagnosis command set A consisting of two “door opening / closing diagnosis” is selected.

  Next, a case will be described in which the information processing apparatus 360 selects a command having the highest recovery rate among a plurality of commands corresponding to the failure code “0001” and the elevator status code “door not open” as the recovery command. The information processing apparatus 360 refers to the recovery diagnosis database 380 illustrated in FIG. 5 and confirms the recovery rate with the highest recovery rate corresponding to the failure code “0001” and the elevator status code “door not open” as the recovery command. Then, the information processing device 360 is configured to execute a recovery operation corresponding to the factor (failure factor 2) caused by the contact failure of the switch having the highest recovery rate b% “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 the restoration diagnosis command set, the failure code “0001” is based on the most frequent failure factor corresponding to the elevator status code “door cannot be opened” or the failure code “0001” and the elevator status code “door cannot be opened”. A selection method based on the restoration rate of the restoration diagnosis command set corresponding to the above will be described. 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 of cases corresponding to the failure code “0001” and the elevator state code “door not open”.

  When the restoration diagnosis command set A is selected in step S106 of FIG. 7, the information processing apparatus 360 transmits the selected restoration diagnosis instruction set A from the communication device 320 as shown in step S107 of FIGS. 2 and 7. 2 and FIG. 7, 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 in FIG. 7, the control panel 210 determines that the elevator 20 is stopped, the weight sensor of the basket 22, the camera in the basket 22, the output of the person sensor in the basket 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. 7 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 is an operation in which the door circuit 13 or the door 26 cannot be opened and the closed state or the half-open state is detected, so that the door 13 or the door 26 can be opened and closed. 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 in FIG. 7, 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 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 of FIG. 7, the process proceeds to step S113 of 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. 8, 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 S115 of FIG. 8, 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. 8, 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. 7, 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. 8, 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 S121 of FIG. 8, 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. 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 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. 7 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. 7 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 receives the failure code “0001”, the elevator status code “door cannot be opened”, and the elevator 20 that are input from the communication device 320. Are stored in the failure history data 377 of the maintenance database 370. Accordingly, all items of the failure history data 377 are updated by storing the current recovery method and the recovery determination result.

  In this remote recovery, the information processing apparatus 360 refers to the recovery diagnosis database 380 shown in FIG. 5 and has the largest number of cases when the failure code is “0001” and the elevator status code is “door cannot be opened”. "Reset door circuit + door open / retry retry", which is a recovery command to execute a recovery action corresponding to the door clogging of the door sill that is a failure factor (Failure factor 1), and a recovery diagnosis operation corresponding to the result of this recovery action A recovery diagnosis command set A composed of two “door opening / closing diagnosis” which is a recovery diagnosis command to be performed is selected and a recovery operation and a recovery diagnosis operation are executed. Therefore, when the elevator 20 is successfully restored, the failure factor “0001” in the restoration diagnosis database 380 shown in FIG. 5 and the failure factor 1 (the door sill clogged) in the case of the elevator status code “door cannot be opened”. Increase the number of cases by one and increase the recovery rate by the amount of successful recovery. Further, the information processing device 360 increases the number of failure factors 1 in the case of the failure code “0001” and the elevator status code “door unopenable” in the failure factor-specific data 378 shown in FIG.

  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. 7 is input. When the determination signal indicating that the restoration of the elevator 20 has failed as shown in step S119 of FIG. 7 is input, the information processing apparatus 360 displays “remote restoration” in the item of the restoration method of the failure history data 377 shown in FIG. “,” “Failure” is stored in the item of the restoration determination result. Further, the number of failure factors 1 (the door sill clogged) in the case of the failure code “0001” and the elevator status code “door cannot be opened” in the recovery diagnosis database 380 shown in FIG. Reduce recovery rate. If the restoration fails, the number of failure factors 1 in the case of the failure code “0001” and the elevator status code “door cannot be opened” in the failure factor-specific data 378 shown in FIG. 4 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 of cases corresponding to the failure code “0001” and the elevator status code “door cannot be opened”. When the information processing device 360 selects the restoration diagnosis command set B based on the restoration rate of the restoration diagnosis command set corresponding to the failure code “0001” and the elevator status code “door cannot be opened”, “door high torque opening / closing” Instead of the recovery operation, a “door open / retry retry” recovery operation is performed in which the doors 13 and 26 are opened and closed again with normal torque. 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 clogs (fault factor 1), which is the most frequent fault factor in the case of the fault code “0001” and the elevator status code “door not open”, has been reached. Become more. For this reason, when the remote recovery system 100 selects the recovery diagnosis command set based on the most frequent failure factor corresponding to the failure code “0001” and the elevator status code “door not open”, at the time of the next remote recovery When the failure code “0001” and the elevator status code “door cannot be opened” are input, 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 device 360 corresponds to the failure code “0001” and the elevator status code “door cannot be opened”. Even when a command having the highest recovery rate among a plurality of commands is selected as a return command, the recovery diagnosis command set A is selected.

  On the other hand, if the remote recovery of the elevator 20 fails, the number of failure factors 1 of the failure code “0001” and the elevator status code “door not open” in the failure factor-specific data 378 shown in FIG. The recovery rate of A decreases. 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 failure factors 2, the information processing device 360 sets the failure code “0001” and the elevator status code “door unopenable”. The command having the highest recovery rate among the corresponding commands 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” and the elevator status code “door open impossible” are input at the next remote restoration. To do. 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.

  In addition, the information processing device 360 selects the restoration diagnosis command set B having the highest restoration rate from among a plurality of commands corresponding to the failure code “0001” and the elevator status code “door not open”, and succeeds in restoring the elevator 20 In this case, the restoration rate of the restoration diagnosis instruction set B is increased. 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. When the information processing apparatus 360 does not select the recovery diagnosis command set B that has failed to recover in the previous remote recovery, the failure code “0001” and the elevator status code “door cannot be opened” are next to the recovery diagnosis command set B. A restoration diagnosis command set A having a high restoration rate corresponding to the above is selected.

  Thus, the remote recovery system 100 increases the number of failure factors and the recovery rate of the selected recovery diagnosis command set when the remote recovery is successful. 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 embodiment described above, the operation of the remote recovery system 100 when the failure code “0001” indicating the failure relating to the doors 13 and 26 and the elevator status code “door open impossible” are output from the control panel 210 is described. did.

  Next, a case will be described in which two elevator status codes of failure code “0001” and “door cannot be opened” and “door cannot be closed” are output from the control panel 210. In this case, the information processing apparatus 360 refers to the failure factor-specific data 378 shown in FIG. 4 and based on the failure code “0001” and the elevator status code that is received more frequently together with the failure code “0001”. In the same manner as described above, the restoration diagnosis command set is selected.

  For example, when the number of times of reception of the elevator status code “door cannot be closed” is greater than the number of times B of reception of the elevator status code “door cannot be closed”, the information processing device 360 recovers as follows. Select the diagnostic command set. The information processing device 360 refers to the recovery diagnosis database 380 shown in FIG. 5 and is linked to the failure factor 1 having the largest number of failure factors corresponding to the elevator status codes of the failure code “0001” and “door cannot be opened”. The restoration diagnosis instruction set A or the restoration diagnosis instruction set B having the highest restoration rate corresponding to the elevator status codes of the failure code “0001” and “Door not open” is selected. As for the operation of the remote recovery system 100 after selecting the recovery diagnosis command set A or the recovery diagnosis command set B, the elevator status code “door cannot be opened” is output from the control panel 210 described above together with the failure code “0001”. This is the same as the case.

  In addition, when the number of times of reception of the elevator status code “door cannot be closed” is larger than the number of times of reception of the elevator status code “door cannot be opened”, the information processing device 360 performs the restoration diagnosis as follows. Select the command set. The information processing apparatus 360 refers to the restoration diagnosis database 380 illustrated in FIG. 6 and is linked to the failure factor 1 having the largest number of failure factors corresponding to the elevator status codes of the failure code “0001” and “door cannot be closed”. The recovery diagnosis command set A or the recovery diagnosis command set B having the highest recovery rate corresponding to the elevator status codes of the failure code “0001” and “door closing impossible” is selected. As for the operation of the remote recovery system 100 after selecting the recovery diagnosis command set A or the recovery diagnosis command set B, the elevator status code “door cannot be opened” is output from the control panel 210 described above together with the failure code “0001”. This is the same as the case.

  Next, a case where a failure code “0002” indicating that the failure is related to the control circuit and an elevator status code “unstartable” are output will be described. Note that the description of the same operation as when the elevator status code of failure code “0001” and “door open impossible” is output is omitted.

  If the failure code is 0002 indicating a failure related to the control circuit and the status code of the elevator is “unable to start”, the engineer 350 inspected on site, and the cause of the output of the failure code “0002” is attached to the control panel 210 The failure may be caused by the failure of the relay being operated (failure factor 4), the failure of the relay drive circuit that drives the relay (failure factor 5), or other failure factor 6. As shown in FIG. 9, failure factor-specific data 378 indicates that when the failure code is “0002” and the status code of the elevator is “unable to start”, there are 100 cases where the failure is a factor (failure factor 4). The data structure is such that 50 cases are caused by a circuit failure (fault factor 5) and 10 cases are caused by other fault factors 6, and the data is arranged in descending order of the number of cases. 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 and the elevator status code that became the basis of the recovery command is Added to the total number of failure factors.

  As shown in FIG. 10, the data structure of the recovery diagnosis database 380 when the failure code is “0002” indicating a failure related to the control circuit and the elevator status code is “unstartable” 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 structure in which a recovery diagnosis command set D, which is a set of two commands “operation diagnosis”, and a recovery rate g% by a recovery operation based on the recovery diagnosis command are linked. Similarly, if there is a problem in the relay drive circuit (fault factor 5), the restoration diagnosis data is “control circuit reset + operation between top floor and bottom floor” as a restoration command in the number data of failure factor 5 and restoration. The data structure is such that 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 h% by a recovery operation based on the recovery diagnosis command are linked as commands. 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 i% are linked to the number data of the failure factor 6. As described above, the recovery diagnosis database 380 is a set of a failure code, an elevator status code, a failure factor corresponding to the failure code and the elevator status code, the number of the failure factors, a recovery command and a recovery diagnosis. The diagnosis command set and the recovery rate are stored in the database in association with each other. Note that the recovery rate is highest in h% of the recovery diagnosis command set E.

  When the failure code is “0002” and the status code of the elevator is “unstartable”, the information processing apparatus 360 has the most number of cases corresponding to the failure code “0002” and the elevator status code shown in FIG. When the restoration diagnosis command set D is selected based on many failure factors, the information processing apparatus 360 transmits the restoration diagnosis command set D to the control panel 210. After executing the control circuit reset operation, the control panel 210 executes a low speed up and down operation for raising and lowering the cage 22 of the elevator 20 at a 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 driving operation Check for any abnormalities. 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 device 360 selects the recovery diagnosis command set E having the highest recovery rate corresponding to the failure code “0002” and the elevator status code “unstartable”, the information processing device 360 sets the recovery diagnosis command set. E is transmitted 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.

  When two elevator status codes of failure code “0002”, “unstartable”, and “interfloor stop” are output from the control panel 210, the information processing device 360 displays failure cause-specific data 378 shown in FIG. , The restoration diagnosis command set is selected in the same manner as described above on the basis of the failure code “0002” and the elevator status code that has been received together with the failure code “0002”.

  For example, when the number of times of reception of the elevator status code “unstartable” is greater than the number of times of reception of the elevator status code “stopped between floors” D times, the information processing device 360 performs the restoration diagnosis as follows. Select the command set. The information processing apparatus 360 refers to the recovery diagnosis database 380 illustrated in FIG. 10 and performs the recovery linked to the failure factor 4 having the largest number of failure factors corresponding to the elevator status codes of the failure codes “0002” and “unstartable”. The diagnosis command set D or the restoration diagnosis command set E having the highest recovery rate corresponding to the fault code “0002” and the elevator status code “unstartable” at h% is selected. As for the operation of the remote recovery system 100 after selecting the recovery diagnosis command set D or the recovery diagnosis command set E, the elevator status code “door cannot be opened” is output from the control panel 210 described above together with the failure code “0001”. This is the same as the case.

  In addition, when the number D of reception of the elevator status code “interval stop” is larger than the number C of reception of the elevator status code “unstartable”, the information processing apparatus 360 may restore the restoration diagnosis command as follows: Select a set. The information processing device 360 is linked to the failure factor 4 having the largest number of failure factors corresponding to the elevator status codes of the failure codes “0002” and “inter-floor stop” with reference to the recovery diagnosis database 380 shown in FIG. The restoration diagnosis command set D or the restoration diagnosis command set E having the highest restoration rate corresponding to the elevator status codes of the failure codes “0002” and “inter-floor stop” is selected at k%. As for the operation of the remote recovery system 100 after selecting the recovery diagnosis command set D or the recovery diagnosis command set E, the elevator status code “door cannot be opened” is output from the control panel 210 described above together with the failure code “0001”. This is the same as the case.

  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. Therefore, when a 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. 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.
