<Database structure>
As shown in FIG. 2, the center side maintenance database 370 stores elevator specification data 371, failure history data 372, and failure factor-specific data 373. Hereinafter, the data structure of the elevator specification data 371, the failure history data 372, and the failure factor-specific data 373 will be described with reference to FIG.

<Structure of elevator specification data>
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.

<Structure of failure history data>
The failure history data 372 has a data structure that stores a management number of the elevator 20, a failure occurrence date and time, a failure code, a failure state code, a recovery method, and a recovery determination result. The failure code is a code output from the control panel 200 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 failure state code is a code composed of terms indicating a failure state that is output together with the failure code from the control panel 200 when a failure occurs in the elevator 20. Examples of the failure status code include “door cannot be opened” and “door cannot be closed”. One fault code may be output together with one fault code, or a plurality of fault status codes may be output together with one fault 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, when the monitor panel 210 causes the control panel 200 to execute the recovery operation of the elevator 20 to perform the recovery, an input such as “monitor side automatic 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.

<Data structure by failure factor>
As shown in FIG. 3, the failure factor-specific data 373 stores the number of times the failure state code is received when a certain failure code and a certain failure state code are output from the control panel 200. The failure factor-specific data 373 includes the failure code according to the result of inspection and inspection conducted by the engineer 350 on site, the number of failure factors corresponding to the failure state code, and the monitor panel 210 controlling the control panel. The total number of failure factors corresponding to the failure code and the failure state code corresponding to the failure status code when the restoration is performed by causing the elevator 20 to perform the restoration operation of the elevator 20 is stored.

  For example, a case will be described where the failure code is 0001 indicating a failure relating to the doors 13 and 26 and the failure status code “Door Unopenable” is received A times. As a result of inspection by the engineer 350 on the spot, the failure code “0001” and the failure status code of “Door not open” are output because the door sill is clogged (failure factor 1), It may be a contact failure of the switch (failure factor 2) or other failure factor 3. Therefore, the failure factor-specific data 373 includes 100 cases of door clogging factors (failure factor 1) when a failure code “0001” and a failure status code “Door cannot be opened” are output, and 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. . When the monitor panel 210 causes the control panel 200 to execute the recovery operation of the elevator 20 and performs recovery, when the recovery of the elevator 20 is successful by the recovery command, the failure code and the failure status code that are the basis of the recovery command are displayed. The number of corresponding failure factors is added to the total number of failure factors.

  Similarly, when the failure code is 0001 indicating a failure relating to the doors 13 and 26 and the failure status code “Door cannot be closed” is received B times, the failure status codes of “0001” and “Door cannot be closed” are the same. 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 373 includes a case where the failure code “0001” and the failure status code “door cannot be closed” are output, the door clogging factor (failure factor 1) is 100 cases, and 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. .

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

  Further, when the failure code is 0002 indicating a failure related to the control circuit and the failure status code is “cannot be activated”, the engineer 350 inspected on site, and as a result, the cause of the failure code “0002” being output to the control panel 200 This may be when the attached relay is defective (failure factor 4), when the relay drive circuit that drives the relay is defective (failure factor 5), or other failure factor 6. As shown in FIG. 4, the failure factor-specific data 373 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. The same applies to the case where the failure code is 0002 indicating a failure related to the control circuit and the failure status code is “interval stop”.

  In the failure factor-specific data 373 shown in FIG. 3, the number of receptions is A> B> C> D.

<Structure of recovery diagnosis database>
As shown in FIG. 4, the recovery diagnosis database 380 includes a recovery diagnosis command set that 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 the failure state code of the failure factor-specific data 373. And the restoration rate (%) which is the ratio which the failure of the elevator 20 restored by execution of the restoration command is 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 373 described above.

  Hereinafter, as shown in FIG. 4, 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 failure 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 to the failure factor 1 count data corresponding to the failure 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. . If the contact failure of the door opening / closing device switch 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 cause 3 data corresponding to the failure status code “door cannot be opened”. It has a configuration. As described above, the recovery diagnosis database 380 is a set of a failure code, a failure state code, a failure factor corresponding to the failure code and the failure state code, the number of the failure factors, a recovery instruction 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 a% is a larger value than the recovery rates b% and c%, and the recovery diagnosis command set A has a higher recovery rate than the recovery diagnosis command set B and the recovery diagnosis command set C. ing.

  Next, the data structure of the recovery diagnosis database 380 when the failure code is “0001” indicating a failure related to the doors 13 and 26 and the failure state code is “door cannot be closed” 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 failure factor 1 data corresponding to the failure status code “Door cannot close”. 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. . 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 + 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 failure status code “door cannot be closed”. It has a configuration. As described above, the recovery diagnosis database 380 is a set of a failure code, a failure state code, a failure factor corresponding to the failure code and the failure state code, the number of the failure factors, a recovery instruction 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.

  Next, 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. In the present embodiment, the recovery rate is highest at g% of the recovery diagnosis command set D.

  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 status code of the elevator is “inter-floor stop” is as described above. The recovery rate is j%, k%, and l%, respectively, in the same manner as the data structure of the recovery diagnosis database 380 when the elevator status code is “stop between floors”. The recovery rate is the highest in k% of the recovery diagnosis command set E.

<Center side recovery process database, structure of data in order of reception count>
Next, the data structures of the reception frequency order data 381 and the center side recovery processing database 390 will be described with reference to FIGS. The reception frequency order data 381 is intermediate data for extracting data from the recovery diagnosis database 380 shown in FIG. 4 and generating the center side recovery processing database 390.

  The reception frequency order data 381 is a database in which combinations of failure codes and failure status codes are extracted from the failure factor-specific data 373 in the descending order of reception frequency. As described above, the number of receptions in the failure factor-specific data 373 is A> B> C> D. The reception frequency order data 381 indicates that the combination of A, which has the highest number of receptions, failure code 0001 and failure status code “cannot open the door” is ranked 1 and the number of receptions B is the second most frequently received failure. Combinations with code 0001 and failure status code “door cannot be closed” are ranked 2; failure codes with the number of receptions C are the third most frequently received, code 0002, and combinations with failure status code “cannot be activated” are rank 3 In addition, the combination in which the failure code is “0002” and the failure status code is “interval stop” is stored in the rank 4 in the order of reception number D and the fourth reception frequency. The reception frequency order data 381 stores, for example, data up to rank 50.

  As shown in FIG. 6, the center side recovery processing database 390 includes the recovery command having the highest recovery rate among the recovery commands corresponding to the combination of the failure code and the failure state code in the reception frequency order data described above. This is a database in which a diagnosis corresponding to a recovery command is combined with a reception frequency order data 381 as a recovery diagnosis command set. For example, when the failure code 0001 of rank 1 and the failure state code are “door cannot be opened”, referring to the recovery diagnosis database 380 shown in FIG. Since it is set A, the recovery diagnosis command set A is combined with rank 1 of the reception frequency order data 381. Similarly, when the failure code 0001 of rank 2 and the failure state code are “door cannot be closed”, referring to the recovery diagnosis database 380 shown in FIG. 4, the recovery rate is highest when the recovery rate is e%. Since it is the command set B, the recovery diagnosis command set B is combined with the rank 2 of the reception frequency order data 381. Similarly, when the failure code 0002 of rank 3 and the failure state code are “unbootable”, the recovery diagnosis command set D having the highest recovery rate is combined with rank 3 of the reception frequency order data 381, and rank 4 When the failure code 0002 and the failure state code are “interval stop”, the recovery diagnosis command set E having the highest recovery rate of k% is combined with the rank 4 of the reception frequency order data 381. As a result, a center side recovery processing database 390 as shown in FIG. 6 is configured. The center-side recovery processing database 390 stores data up to, for example, a rank of 50, similarly to the reception count order data 381.

<Monitoring maintenance database structure>
Hereinafter, the monitor-side maintenance database 240 will be described with reference to FIG. The monitor-side maintenance database 240 includes elevator specification data 241, remote inspection history data 242, modulation history data 243, and failure history data 244.

  The elevator specification data 241 and the failure history data 244 are the same as the elevator specification data 371 and the failure history data 372 described above with reference to FIG.

  The remote inspection history data 242 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 outputting a remote inspection command from the monitor panel 210 to the control panel 200 according to a preset schedule such as once a month. The control panel 200 of the elevator 20 moves the basket 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 output from the control panel 200 to the monitor panel 210 and stored in the remote inspection history data 242. The remote inspection may be performed according to an instruction from the remote monitoring center 300.

  The modulation history data 243 has a data structure for storing a management number of the elevator 20, a modulation occurrence date / 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 the inspection of the brake torque, it is within the allowable value, but when the previous inspection or when the deviation of the elevator 20 from the value of the previous inspection result is large, the modulation item Recorded as “brake torque” inside.

<Monitor side recovery database structure>
The structure of the monitor-side recovery process database 250 is the same as that of the center-side recovery process database 390 described above with reference to FIG.

<Elevator system operation>
Next, the operation of the elevator system 100 when the elevator 20 according to the present embodiment fails will be described with reference to FIGS. 9 to 11.

<Generation of center side recovery process database and monitor side recovery process database>
First, generation of the center side recovery processing database 390 and the monitor side recovery processing database 250 will be described with reference to FIG.

  As described above, the center side recovery processing database 390 stores the recovery command with the highest recovery rate and the recovery command among the recovery commands corresponding to the combination of the failure code and the failure state code in the reception frequency order data 381. This is a database in which the corresponding diagnosis is combined with the reception frequency order data 381 as a restoration diagnosis command set.

  As shown in step S11 of FIG. 9, the center-side information processing device 360 extracts combinations of failure codes and failure state codes from the failure cause-specific data 373 shown in FIG. The reception frequency order data 381 shown is generated. In the present embodiment, the number of receptions in the failure factor-specific data 373 shown in FIG. 3 is A> B> C> D. The center-side information processing device 360 extracts a combination of A, which has the highest number of receptions, the failure code is 0001, and the failure state code is “unable to open the door” from the failure cause-specific data 373, and the rank of the reception frequency order data 381 1 is stored. Further, the center-side information processing device 360 has the combination of “0001” for the second most common failure code and “No door closing” as the second most common fault code, and rank “2” for the combination of the failure status code “cannot close the door”. The combination of failure code 0002 and failure status code “unbootable” in rank 3, combination of reception number D and fourth most frequent failure code 0002, failure status code “interval stop” combination Are stored in rank 4, respectively. Similarly, the center-side information processing device 360 extracts combinations of failure codes and failure status codes from the failure cause-specific data 373 in descending order of the number of receptions, and stores them in the reception frequency order data 381 up to rank 50, for example. Go.

  Next, as shown in step S12 of FIG. 9, the center-side information processing device 360 refers to the recovery diagnosis database 380, and includes the recovery command corresponding to the combination of the failure code and the failure status code in the reception frequency order data 381. Thus, it is combined with the reception frequency order data 381 as a recovery diagnosis command set having the highest recovery rate. When the failure code 0001 of rank 1 and the failure state code are “door cannot be opened”, referring to the recovery diagnosis database 380 shown in FIG. 4, the number of times of receiving the recovery diagnosis command set A having the highest recovery rate a% Combined with rank 1 of the forward data 381. Similarly, when the failure code 0001 of rank 2 and the failure state code are “door cannot be closed”, the restoration diagnosis command set B having the highest restoration rate e% is combined with rank 2 of the reception frequency order data 381. Similarly, when the failure code 0002 of rank 3 and the failure state code are “unbootable”, the recovery diagnosis command set D having the highest recovery rate is combined with rank 3 of the reception frequency order data 381, and rank 4 When the failure code 0002 and the failure state code are “interval stop”, the recovery diagnosis command set E having the highest recovery rate of k% is combined with the rank 4 of the reception frequency order data 381. Thereafter, the restoration diagnosis command set is similarly combined up to rank 50. In this way, the center-side information processing device 360 generates a data set as shown in FIG.

  The center-side information processing device 360 stores the generated data set in the center-side recovery processing database 390. Further, the center side information processing apparatus 360 updates the center side recovery processing database 390 at intervals of a predetermined period, for example, one week or one month.

  As shown in step S13 of FIG. 9, the center side information processing device 360 updates the contents of the center side recovery processing database 390 at the timing of updating the center side recovery processing database 390, the center side communication device 320, the communication network 30, and the monitor. The information is transmitted to the monitor side information processing device 230 of the monitor panel 210 via the side communication device 220.

  As shown in step S14 of FIG. 9, the monitor-side information processing device 230 updates the contents of the monitor-side recovery process database 250 with the received contents of the center-side recovery process database 390. As described above, the monitor-side recovery processing database 250 is data having the same contents as the center-side recovery processing database 390.

<Operation of the elevator system when a failure occurs in the elevator>
Next, the operation of the elevator system 100 when a failure occurs in the elevator 20 will be described with reference to FIG.

  As shown in step S <b> 101 of FIG. 10, the monitor panel 210 is on standby until a failure occurs in the elevator 20. If a failure occurs in the elevator 20, the control panel 200 proceeds to step S <b> 102 and outputs a failure code and a failure state code to the monitor panel 210.

  As shown in step S <b> 103 of FIG. 10, the failure code and the failure state code output from the control panel 200 are input to the monitor-side information processing device 230. As shown in step S104 in FIG. 10, the monitor-side information processing device 230 determines whether the recovery operation by the monitor panel 210 can be executed, that is, whether the monitor-side automatic recovery is possible. This determination is made as follows.

  First, the monitor-side information processing device 230 takes passengers into the car 22 of the elevator 20 from the output of the control panel 200, for example, the weight sensor of the car 22, the camera in the car 22, the human sensor in the car 22, and the like. Check if there is any. When there are passengers in the basket 22, it is determined that the monitor-side automatic recovery is not possible. Then, the process proceeds to step S105 in FIG. 10, and a signal indicating that the monitor-side automatic recovery cannot be performed to the center-side information processing device 360 via the monitor-side communication device 220, the communication network 30, and the center-side communication device 320, and a failure code and a failure state code. To send. Then, the process proceeds to step S114 in FIG. 10 to update the monitor-side maintenance database 240 and terminate the operation.

  If it is determined that there is no passenger in the basket 22, the monitor-side information processing device 230 stores in the monitor-side recovery processing database 250 a recovery diagnosis instruction set corresponding to the combination of the received failure code and failure status code. Judge whether. For example, the group having the failure code 0001 and the failure state code “cannot open the door” is stored in the monitor-side recovery processing database 250 shown in FIG. On the other hand, in the case of a combination in which the failure code and the failure state code are not stored in the monitor side recovery processing database 250, the process proceeds to step S105 in FIG. 10 and the monitor side communication device 220, the communication network 30, and the center side communication device 320 are changed. The monitor-side information processing device 360 is transmitted a signal indicating that the monitor-side automatic recovery is impossible, a failure code, and a failure status code. Then, the process proceeds to step S114 in FIG. 10 to update the monitor-side maintenance database 240 and terminate the operation.

  When the monitor-side information processing device 230 determines that the recovery diagnosis command set corresponding to the combination of the received failure code and failure status code is stored in the monitor-side recovery processing database 250, the monitor-side maintenance database 240 With reference to the failure history data 244, it is confirmed whether or not the elevator 20 has recently transmitted a failure signal with the same failure code “0001”.

  When a failure signal with the same failure code “0001” is transmitted, the monitor-side information processing device 230 determines that it is better to dispatch the engineer 350 to the building 10 than the monitor-side automatic recovery. , NO is determined in step S104 of FIG. Then, the process proceeds to step S105 in FIG. 10, a monitor-side automatic recovery impossible signal, a failure code, and a failure status code are transmitted to the remote monitoring center, and the process proceeds to step S114 in FIG. 10 to update the monitor-side maintenance database 240. To finish the operation.

  The monitor-side information processing device 230 has no passenger in the car 22, and a recovery diagnosis command set corresponding to the combination of the received failure code and failure status code is stored in the monitor-side recovery processing database 250. If it is determined that a failure signal with the same failure code “0001” has not been transmitted, it is determined in step S104 in FIG. Then, the process proceeds to step S106 in FIG. 10, and a recovery diagnosis command set that is a set of the recovery command and the recovery diagnosis command corresponding to the received failure code and failure status code is selected from the monitor side recovery processing database 250. Then, as shown in step S107 of FIG. For example, when the failure code is 0001 and the failure state code is “door cannot be opened”, the monitor-side information processing device 230 selects the recovery diagnosis command set A with reference to the monitor-side recovery processing database 250 shown in FIG. The restoration diagnosis command set A is a set of two commands: “door circuit reset + door high torque opening / closing” as a restoration command and “door opening / closing diagnosis” as a restoration diagnosis command. Therefore, the monitor-side information processing device 230 outputs a “door circuit reset + door high torque opening / closing” restoration command and a “door opening / closing diagnostic” restoration diagnostic command to the control panel 200.

  As shown in step S108 of FIG. 10, when the restoration diagnosis command and the restoration diagnosis command are input from the monitor-side information processing device 230, the control panel 200 stops the elevator 20 as shown in step S109 of FIG. And that there are no passengers in the cage 22 based on outputs from the weight sensor of the cage 22, the camera in the cage 22, the human sensor in the cage 22, and the like. When the control panel 200 confirms that the elevator 20 is stopped and that there are no passengers in the basket 22, the control panel 200 starts the remote recovery from the speaker of the communication device installed in the basket 22. The elevator door will open and close. "

  Then, the control panel 200 proceeds to step S110 in FIG. 10 and performs a recovery operation. Since the received restoration command is a restoration command of “door circuit reset + door high torque opening / closing” included in the restoration diagnosis command set A, the control panel 200 first resets the door circuit of the control panel 200. To do. 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 200 increases the torque of the drive motor of the door 13 and the door 26 by 20 to 30% than usual, and opens and closes the door 13 and the door 26 with a force larger than usual. This operation is an operation in which the garbage stuck in the door sill is moved from the sill and the opening / closing operation of the doors 13 and 26 is restored to the normal state.

  As shown in step S111 of FIG. 10, the control panel 200 restores the garbage stuck in the thresholds of the doors 13 and 26 to check whether the doors 13 and 26 have been opened and closed. “Door open / close diagnosis” which is a diagnosis command is executed. The control panel 200 opens and closes the door 13 and the door 26 with a normal torque, and can the opening and closing operation be performed in 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 200 opens and closes the door 13 and the door 26 by lowering the torque of the drive motor by about 20% than usual, and checks whether there is an abnormality in the opening and closing time.

  When the execution of the recovery diagnosis operation is completed, the control panel 200 proceeds to step S112 in FIG. 10 and outputs the determination result of the result of the recovery operation to the monitor side information processing device 230. When the control panel 200 determines that the doors 13 and 26 have recovered to the normal state by the recovery diagnosis operation, the control panel 200 outputs a determination result signal that the elevator 20 has recovered to the monitor-side information processing device 230. When it is determined that the doors 13 and 26 have not been restored to the normal state by the restoration diagnosis operation as a result of the restoration diagnosis operation, a determination result signal indicating that the restoration of the elevator 20 has failed is output.

  As shown in step S113 of FIG. 10, the monitor-side information processing device 230 displays the determination result input from the control panel 200, the failure code, and the failure status code, the monitor-side communication device 220, the communication network 30, and the center-side communication. The information is transmitted to the center information processing device 360 via the device 320.

  The monitor-side information processing device 230 updates the monitor-side maintenance database 240 based on the result of the failure processing of the elevator 20 and ends the operation.

  Next, the operation of the center side information processing apparatus 360 will be described with reference to FIG. As shown in steps S201 and S202 of FIG. 11, the center-side information processing device 360 receives a signal indicating that the monitor-side automatic recovery cannot be performed or a recovery failure signal from the monitor-side information processing device 230. Is displayed on the display 331 of the remote monitoring center 300. As shown in step S205 in FIG. 11, when the monitor 334 confirms this display, the supervisor 334 causes the elevator 20 to stop operating and performs an announcement operation. 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 S206 of FIGS. Further, the center-side information processing device 360 updates the center-side maintenance database 370 and the recovery diagnosis database 380 as shown in steps S203 and S204 of FIG.

  When the center-side information processing device 360 receives the determination signal that the elevator 20 has been restored, the center-side information processing device 360 determines YES in step S202 of FIG. 11 and proceeds to steps S203 and S204 of FIG. Update the recovery diagnostic database.

  The center-side information processing device 360 updates the center-side maintenance database 370 as follows.

  When the determination signal that the elevator 20 has been restored is input, the center-side information processing device 360 displays “recovery” in the item “recovery method” of the failure history data 372 and “restore” in the item of the restoration determination result. Is stored. Further, the received failure code, “0001”, failure status code “door cannot be opened”, elevator 20 management number, and failure date and time are stored in the failure history data 372 of the center side maintenance database 370.

  The center side information processing apparatus 360 updates the restoration diagnosis database 380 shown in FIG. 4 as follows.

  When the center-side information processing device 360 successfully recovers the elevator 20 by the monitor-side automatic recovery, the center-side information processing device 360 increases the number of failure factors corresponding to the combination of the failure code and the failure diagnosis code by one, Only increase the restoration rate of the corresponding restoration diagnosis command set. Further, the center-side information processing device 360 increases the number of times of reception of the combination of the failure code and the failure state code of the failure factor-specific data 373 shown in FIG. Do more.

  Further, when the restoration of the elevator 20 fails due to the monitor side automatic restoration, the restoration rate of the corresponding restoration diagnosis command set is lowered by the amount of the restoration failure. Further, the center-side information processing device 360 increases the number of receptions of the combination of the failure code and the failure state code of the failure factor-specific data 373 shown in FIG. At this time, the number of failure factors is not changed.

  Thus, the recovery diagnosis database 380 is updated according to the result of the monitor-side automatic recovery. When a predetermined period has elapsed, the center-side recovery processing database 390 is updated based on the updated recovery diagnosis database 380, thereby updating the monitor-side recovery processing database 250.

  As described above, the elevator system 100 according to the present embodiment can perform automatic monitor-side recovery of the elevator 20 using a recovery command with a high recovery rate corresponding to the failure code and the failure state code.

  Further, the elevator system 100 according to the present embodiment transmits a failure code and a failure status code to the remote monitoring center 300, or receives a recovery command and a recovery diagnostic command when the frequently occurring failure of the elevator 20 occurs. Therefore, when the 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. Can be planned.

  Furthermore, since the elevator system 100 of the present embodiment stores the maintenance data of the elevator 20 in the monitor-side maintenance database in the monitor panel 210, the capacity of the center-side maintenance database 370 of the remote monitoring center 300 is suppressed. And the amount of communication between the remote monitoring center 300 and the monitor panel 210 can be suppressed.
