<Database structure>

As shown in FIG. 2, the elevator-side maintenance database 370 stores elevator specification data 371, failure history data 372, and failure factor-specific data 373. Hereinafter, with reference to FIG. 3, the data structure of elevator specification data 371, the failure history data 372, and the failure cause-specific data 373 is demonstrated.

<Structure of Elevator Specification Data>

The elevator specification data 371 has a data structure which stores the management number, model, manufacture date, manufacture number, name of the installation building, and data of the use of the installation building of the elevator 20. The use of the installation building is, for example, an office, a general residence, a restaurant, a school, or the like.

<Structure of Fault History Data>

The failure history data 372 has a data structure that stores a management number of the elevator 20, a date and time of occurrence of a failure, a failure code, a failure status code, a recovery method, and a recovery determination result. The failure code is a code that combines a number or numerals and English letters outputted from the control panel 200 when a failure occurs in the elevator 20. The kind of fault code is about 1000 types, for example. The failure status 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. The failure status codes are, for example, "Do not open door" and "Do not close door". One fault status code may be output together with one fault code, and a plurality of fault status codes may be output together with one fault code. In the item of the recovery method, for example, when the technician 350 is dispatched to inspect, inspect, and recover, it is inputted as "explain engineer." In addition, when the monitor panel 210 executes a recovery operation of the elevator 20 to the control panel 200 to perform the recovery, the monitor panel 210 is input like "monitor side automatic recovery". When the elevator 20 is restored and the operation resumes, the item of the recovery determination result is input like "recovery". In addition, when the elevator 20 fails to recover, the item of the repair determination result is input as "failure".

<Structure of Data by Failure Factors>

As shown in Fig. 3, data for each of the failure factors 371 stores the number of times that a failure code is received when a failure code and a failure status code are output from the control panel 200. FIG. In addition, the failure factor-specific data 373 includes the failure code resulting from the technician 350's on-site inspection and inspection, the number of failure factors corresponding to the failure status code, and the monitor panel 210. The control panel 200 stores the total number of the failure codes when the recovery operation of the elevator 20 is executed and the recovery codes are executed, and the total number of failure factors corresponding to the failure status codes.

For example, a case where the failure code is 0001 indicating a failure with respect to the doors 13 and 26, and the failure status code has been received A times of "Do not open door" will be described. When the technician 350 checks on-site, the output factor of the fault status codes "0001" and "Do not open door" is that the door threshold is clogged (failure factor 1) or the door open / close switch is in poor contact. (Fault factor 2) or other failure factor 3. Therefore, when the failure status code "3,000" and "Do not open door" are outputted, the data for each failure factor 373 are 100 cases of clogging factors (failure factor 1) on the door threshold, door opening and closing. It is a data structure such that 50 cases of switch contact failure of a device is a factor (failure factor 2) and 10 cases of another failure factor 3, and the data is arranged in order of the number of cases. . When the monitor panel 210 restores the elevator 20 to the control panel 200 by performing the recovery operation, the failure which became the basis of the recovery command when the recovery of the elevator 20 is successful by the recovery command. The number of failure factors corresponding to the code and the fault condition code is added to the total number of failure factors.

In addition, even when the failure code is 0001 indicating a failure with respect to the doors 13 and 26 and the failure status code "No door closing" has been received B times, the failure states of the failure codes "0001" and "Do not close door" are similar. The output factor of the code may be a door trash clogging (failure factor 1), a poor contact of the switch of the door opener (failure factor 2), or another failure factor 3. Therefore, when the failure status data of the failure factor "0001" and "Do not close the door" is output, 100 cases of the clogging factor (failure factor 1) of the door threshold are 100, It is a data structure such that 50 cases of switch contact failure of a device is a factor (failure factor 2) and 10 cases of another failure factor 3, and the data is arranged in order of the number of cases. .

The same applies to the case where two fault status codes of "Do not open door" and "Do not close door" are output together with the fault code "0001".

In addition, when the fault code is 0002 indicating a fault with respect to the control circuit and the fault condition code is "not startable", the factor 350 outputs the fault code "0002" as a result of the inspection by the technician 350 is the control panel 200. ) Is defective (failure factor 4), or the relay drive circuit driving the relay is defective (failure factor 5), or other failure factor 6. As shown in Fig. 4, when the failure factor-specific data 373 is the failure code "0002" and the elevator status code is "not startable", 100 cases of the failure of the relay as a factor (failure factor 4), The data structure is such that 50 cases in which the failure of the relay drive circuit is the factor (failure factor 5) and 10 cases in the other failure factor 6 are configured so that the data is arranged in order of the number of cases. The same applies to the case where the fault code is 0002 indicating a fault relating to the control circuit and the fault status code is "interlayer stop".

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

<Structure of Recovery Diagnostic Database>

As shown in Fig. 4, the recovery diagnostic database 380 is a set of recovery commands and recovery diagnosis commands in order of the number of failure factors corresponding to the failure code and the failure status code of the data for each failure factor 371. A recovery diagnosis command set and a recovery rate (%) which is a rate at which the failure of the elevator 20 is restored by the execution of the recovery command are stored. The recovery diagnostic database 380 is a database in which the recovery diagnosis command set and the recovery rate are linked to the above-described failure cause data 373.

Hereinafter, as shown in FIG. 4, the data configuration of the recovery diagnosis database 380 when the failure code is "0001" indicating a failure with respect to the doors 13 and 26 and the failure status code is "Do not open door". Explain. If the door threshold clogging is a factor (failure factor 1), the recovery diagnostic data is a "door circuit reset + door high" as a recovery command to the count data of the failure factor 1 in which the fault status code corresponds to "Do not open door." ) Is a data structure in which a recovery diagnosis command set A which is a set of two commands of "torque open / close" and a "door open / close diagnosis" is linked with the recovery rate a% by the recovery operation by this recovery command. When the contact failure of the switch of the door open / close device is a factor (failure factor 2), the recovery diagnostic data is set as the recovery command to the number data of the failure factor 2 whose fault status code corresponds to "Do not open door". A retrieval diagnosis command set B, which is a set of two commands of "door open / close retry" and "door open / close diagnosis" as a retrieval diagnosis command, has a data structure in which the recovery rate b% of the retrieval operation by this retrieval command is linked. Similarly, in the case of the failure factor 3, the recovery diagnostic data has a data structure in which the recovery diagnosis command set C and the recovery rate c% are linked to the number data of the failure factor 3 in which the failure status code corresponds to "Do not open the door." In this way, the recovery diagnosis database 380 is a recovery code, which is a set of a failure code, a failure status code, a failure factor corresponding to the failure code and a failure status code, the number of the failure factors, a recovery command and a recovery diagnosis. Corresponding to the diagnostic command set and the recovery rate, the data is stored in the database. In the present embodiment, the recovery rate a% is larger 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.

Next, a description will be given of the data configuration of the recovery diagnosis database 380 when the failure code is "0001" indicating a failure with respect to the doors 13 and 26, and the failure status code is "Do not close door." When the door threshold clogging is a factor (failure factor 1), the recovery diagnostic data is "door circuit reset + door high torque opening / closing" as a recovery command to the number data of failure factor 1 in which the failure status code corresponds to "Do not close door." Is a data structure in which a recovery diagnosis command set A, which is a set of two commands of "door open / close diagnosis" as a recovery diagnosis command, and the recovery rate d% by the recovery operation by this recovery command are linked. When the contact failure of the switch of the door opener is a factor (failure factor 2), the recovery diagnostic data is set as the recovery command to the number data of the failure factor 2 in which the failure status code corresponds to "Do not close the door." The reconstruction diagnosis command set B, which is a set of two commands of "door open / close retry" and "door open / close diagnosis" as a recovery diagnosis command, has a data structure in which the recovery rate e% of the recovery operation by this recovery command is linked. Similarly, in the case of the failure factor 3, the recovery diagnostic data has a data structure in which the recovery diagnosis command set C and the recovery rate f% are linked to the number data of the failure factor 3 in which the failure status code corresponds to "Do not close the door." In this way, the recovery diagnosis database 380 is a recovery code, which is a set of a failure code, a failure status code, a failure factor corresponding to the failure code and a failure status code, the number of the failure factors, a recovery command and a recovery diagnosis. Corresponding to the diagnostic command set and the recovery rate, the data is stored in the database. On the other hand, in this embodiment, the recovery rate e% is 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.

Next, a description will be given of the data configuration of the recovery diagnosis database 380 when the failure code is "0002" indicating a failure with respect to the control circuit and the elevator status code is "not startable". When there is a fault in the relay (failure factor 4), the recovery diagnostic data is stored in the number data of the failure factor 4 as the "restore control circuit reset + low speed up and down operation" as a recovery command, and as "restore diagnosis command" for each floor operation and high speed. The recovery diagnosis command set D, which is a set of two commands of "operation diagnosis", and a data structure in which the recovery rate g% by the recovery operation by this recovery diagnosis command is linked together. Similarly, when there is a failure in the relay drive circuit (failure factor 5), the recovery diagnostic data is the number of failure factor 5 data as "control circuit reset + uppermost floor, the lowest floor operation" as a recovery command, and "each floor operation" as a recovery command. The recovery diagnosis command set E, which is a set of two commands of "high speed operation diagnosis", and the data rate of the recovery rate h% by the recovery operation by this recovery diagnosis command are linked. Similarly, in the case of the failure factor 6, the recovery diagnostic 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 this embodiment, the recovery rate is the highest at g% of the recovery diagnosis command set D.

The data configuration of the recovery diagnostic database 380 when the fault code is "0002" indicating a fault with respect to the control circuit and the elevator status code is "interlayer stop" is that the fault code described above indicates a fault with respect to the control circuit. Similarly to the data configuration of the recovery diagnostic database 380 when " 0002 " and the elevator status code is " interlayer stop ", the recovery rates are set to j%, k% and l%, respectively. The recovery rate is the highest k% of the recovery diagnosis command set E.

<Center-side recovery processing database, structure of data received in order>

Next, the data structures of the received count data 381 and the center-side recovery processing database 390 will be described with reference to FIGS. 5 and 6. The reception count 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 the combination of the failure code and the failure status code is extracted from the failure factor-specific data 373 in the order of increasing the number of reception. As described above, the number of receptions in the failure cause-specific data 373 is A> B> C> D. The number of reception order data 381 is a combination of the highest number of receptions A, the failure code 0001 and the failure status code "Do not open the door" as the rank 1, the number of receptions is B, and the second highest number of receptions. The combination with fault code 0001 and fault status code "Do not close door" is ranked 2, the combination with the number of times C and the third most frequently received fault code is 0002, and the fault status code is "not startable". In 3, the combination where the number of receptions is D, the fourth highest number of failure codes is 0002, and the failure status code is "interlayer stop" is stored in rank 4. The reception count order data 381 stores the data of order 50, for example.

As shown in Fig. 6, the center-side recovery processing database 390 responds to the recovery command having the highest recovery rate among the recovery commands corresponding to the combination of the failure code and the failure status code in the order of reception count data described above, and the recovery command. Is a database in which the diagnosis is combined with the received count order data 381 as a recovery diagnosis command set. For example, when the failure code 0001 in the rank 1 and the failure status code are "Do not open the door", referring to the recovery diagnosis database 380 shown in FIG. 4, the highest recovery rate is a recovery diagnosis command of a recovery rate a%. Since it is set A, the recovery diagnosis command set A is combined with the rank 1 of the received count order data 381. Similarly, when the failure code 0001 in the rank 2 and the failure status code are "Do not close the door", referring to the recovery diagnosis database 380 shown in FIG. 4, the highest recovery rate is the recovery diagnosis command set B having a recovery rate e%. Therefore, the recovery diagnosis command set B is combined with the rank 2 of the received number order data 381. Similarly, when the fault code 0002 in the rank 3 and the fault status code are "not startable", the recovery diagnosis command set D having the highest recovery rate g% is combined with the rank 3 of the received count order data 381, and the rank 4 When the failure code 0002 and the failure status code are "interlayer stop", the recovery diagnosis command set E of k% having the highest recovery rate is combined with the rank 4 of the received count order data 381. This constitutes a center-side recovery processing database 390 as shown in FIG. The center-side recovery processing database 390 stores data up to, for example, 50, similarly to the reception count order data 381.

<Structure of Monitor Side Maintenance Database>

Hereinafter, the monitor side maintenance database 240 is demonstrated, referring FIG. The monitor-side maintenance database 240 has elevator specification data 241, remote check history data 242, modulation history data 243, and failure history data 244.

Since 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. 3, description thereof is omitted.

The remote check history data 242 has a data structure that stores the management number, remote check date and time, remote check item, and remote check result of the elevator 20. 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 car 22 of the elevator 20 shown in FIG. 1 to a predetermined floor. During this movement, various sensors attached to the elevator 20 check whether there are any problems in driving performance (acceleration or presence of abnormal sounds), door opening, closing, brakes, emergency batteries, external contact 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. In addition, the remote inspection may be performed by an instruction from the remote monitoring center 300.

The modulation history data 243 has a data structure that stores the management number of the elevator 20, the date and time of the modulation, the modulation item, and the modulation correspondence result. The modulation of the elevator 20 is a case where the result of the inspection, inspection, maintenance work or remote inspection by the technician 350 does not reach the abnormal value, but is changed from the normal value of the elevator 20. Refers to. For example, if the result of the inspection of the brake torque is within the allowable value, but the difference between the value of the previous inspection result of the elevator 20 or the previous inspection result of the elevator 20 is large, the " Brake torque ".

<Structure of Monitored Recovery Database>

It is a database in which the diagnosis is combined with the received count order data 381 as a recovery diagnosis command set.

As shown in step S11 of FIG. 9, the center-side information processing apparatus 360 extracts the combination of the fault code and the fault status code in order of increasing number of receptions from the data for each fault cause 337 shown in FIG. And the received data order data 381 shown in Fig. 5 is generated. In this embodiment, the frequency | count of reception in the failure cause-specific data 373 shown in FIG. 3 is A> B> C> D. The center-side information processing apparatus 360 extracts a combination of the failure number 0001 and the failure status code "No door opening", which is A, which has the greatest number of receptions, from the failure factor-specific data 373 and receives the sequence number of data ( It is stored in the rank 1 of 381). In addition, the center side information processing apparatus 360 ranks the combination where the number of receptions is B and the second most frequent failure code is 0001 and the failure status code is "Do not close door" in the rank 2, and the number of receptions is C and the third time.

The combination is stored in rank 4, respectively. Similarly, the center-side information processing apparatus 360 extracts the combination of the failure code and the failure status code from the failure factor-specific data 373 in the order of receiving the largest number of times, for example, the order of receiving count data up to 50 ranks. It is stored in (381).

Next, as shown in step S12 of FIG. 9, the center-side information processing apparatus 360 corresponds to the combination of the failure code and the failure status code in the received data order data 381 while referring to the recovery diagnosis database 380. The recovery command having the highest recovery rate among the recovery commands and the diagnosis corresponding to the recovery command are combined with the received number order data 381 as a recovery diagnosis command set. When the failure code 0001 in the rank 1 and the failure status code are "Do not open the door", referring to the recovery diagnostic database 380 shown in FIG. 4, the recovery diagnosis command set A having the highest recovery rate a% is received in order of the number of times received. It is combined with the rank 1 of the data 381. Similarly, when the failure code 0001 in the rank 2 and the failure status code are "Do not close the door", the recovery diagnosis command set B having the recovery rate e% having the highest recovery rate is combined with the rank 2 in the received count order data 381. Similarly, when the fault code 0002 in the rank 3 and the fault status code are "not startable", the recovery diagnosis command set D having the highest recovery rate g% is combined with the rank 3 of the received count order data 381, and the rank 4 When the failure code 0002 and the failure status code are "interlayer stop", the recovery diagnosis command set E of k% having the highest recovery rate is combined with the rank 4 of the received count order data 381. Similarly, the recovery diagnosis command sets are combined up to rank 50. In this way, the center-side information processing apparatus 360 generates a data set as shown in FIG.

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

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

As shown in step S14 of FIG. 9, the monitor-side information processing apparatus 230 updates the contents of the monitor-side recovery processing database 250 with the contents of the received center-side recovery processing database 390. In this way, the monitor-side recovery processing database 250 is the same data as the center-side recovery processing database 390.

<Operation System of Elevator System in the Event of Elevator Failure>

Next, the operation of the elevator system 100 when a failure occurs in the elevator 20 will be described with reference to FIG. 10.

As shown in step S101 of FIG. 10, the monitor panel 210 waits until a failure occurs in the elevator 20. When a failure occurs in the elevator 20, the control panel 200 proceeds to step S102 to output a failure code and a failure state code to the monitor panel 210. FIG.

As shown in step S103 of FIG. 10, the fault code and the fault condition code output by the control panel 200 are input to the monitor-side information processing apparatus 230. As shown in step S104 of FIG. 10, the monitor-side information processing apparatus 230 determines whether the recovery operation by the monitor panel 210 can be executed, and whether monitor-side automatic recovery is possible. This determination is performed as follows.

First, the monitor-side information processing apparatus 230 lifts the elevator from an output of the control panel 200, for example, a weight sensor of the car 22, a camera in the car 22, a seal sensor in the car 22, and the like. It is checked whether or not there is a passenger inside the car 22 of (20). If there is a passenger in the car 22, it is determined that automatic recovery on the monitor side is impossible. In step S105 of FIG. 10, the monitor-side automatic recovery impossible signal is transmitted 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 transmits the fault code and fault status code. The flow advances to step S114 in FIG. 10 to update the monitor side maintenance database 240 to end the operation.

When it is determined that there is no passenger in the car 22, the monitor-side information processing apparatus 230 stores a recovery diagnosis command set corresponding to the combination of the received failure code and the failure status code in the monitor-side recovery processing database 250. Determine whether there is. For example, the pair in which the failure code is 0001 and the failure status code "Do not open the door" is stored in the monitor-side recovery processing database 250 shown in Fig. 8, and the flow proceeds to the next condition determination. On the other hand, in the case where the fault code and the fault condition code are combinations not stored in the monitor-side recovery processing database 250, the flow advances to step S105 in FIG. 10, where the monitor-side communication device 220, the communication network 30, The monitor side automatic recovery impossibility signal, fault code, and fault status code are transmitted to the center side information processing apparatus 360 via the center side communication device 320. The flow advances to step S114 in FIG. 10 to update the monitor side maintenance database 240 to end the operation.

When the monitor-side information processing apparatus 230 determines that the recovery diagnosis instruction set corresponding to the combination of the received failure code and the failure status code is stored in the monitor-side recovery processing database 250, the monitor-side maintenance database ( With reference to the failure history data 244 of 240, it is checked whether the elevator 20 has recently sent out a failure signal with the same failure code "0001".

And when the fault signal by the same fault code "0001" is transmitted, it is judged that the monitor side information processing apparatus 230 dispatches the technician 350 to the building 10 rather than the monitor side automatic recovery. In step S104 of FIG. 10, it is determined as "no". Then, the process proceeds to step S105 of FIG. 10 to transmit the monitor side auto-recovery non-recovery signal, the fault code, and the fault status code to the remote monitoring center, and the process proceeds to step S114 of FIG. Update to complete the operation.

The monitor-side information processing apparatus 230 has no passengers in the car 22, and a set of recovery diagnosis commands corresponding to the combination of the received failure code and the failure status code is stored in the monitor-side recovery processing database 250. When it is determined that the elevator 20 does not transmit a failure signal with the same failure code "0001", it is determined that the monitor side automatic recovery is possible in step S104 of FIG. Then, the flow advances to step S106 of FIG. 10 to select a recovery recovery instruction set of the join recovery recovery command corresponding to the received failure code and failure status code from the monitor-side recovery processing database 250. And as shown in step S107 of FIG. 10, it outputs to the control panel 200. FIG. For example, when the failure code is 0001 and the failure status code is "Do not open door", the monitor-side information processing apparatus 230 refers to the monitor-side recovery processing database 250 shown in FIG. 8 and sets a recovery diagnosis command. Select A The recovery diagnosis command set A sets two commands of "door circuit reset + door high torque open / close" as a recovery command and "door open / close diagnosis" as a recovery diagnosis command. Therefore, the monitor-side information processing apparatus 230 outputs to the control panel 200 a recovery command of "door circuit reset + door high torque opening and closing" and a recovery diagnosis command of "door opening and closing diagnosis".

As shown in step S108 of FIG. 10, when the recovery command and the recovery diagnosis command are input from the monitor-side information processing apparatus 230, the elevator 20 causes the elevator 20 to exit. It is confirmed that there is no passenger in the car 22 from the outputs of the stationary vehicle, the weight sensor of the car 22, the camera in the car 22, the person sensor in the car 22, and the like. When the control panel 200 confirms that the elevator 20 is stopped and there are no passengers in the car 22, the control panel 200 starts the remote recovery from the speaker of the communication device installed in the car 22. Open and close the door. " Etc. broadcast.

The control panel 200 proceeds to step S110 in FIG. 10 to perform a recovery operation. Now, since the received recovery command is a recovery command of "Door circuit reset + door high torque opening and closing" included in the recovery diagnosis command set A, the control panel 200 first resets the door circuit of the control panel 200. do. This operation resets the state in which the door circuit 13 or the door 26 is incapable of opening, and detects the closed state or the half-open state, and enables the door 13 or the door 26 to be opened and closed. It is an operation. Subsequently, the control panel 200 opens and closes the door 13 and the door 26 with a force greater than usual by increasing the torque of the drive motors of the door 13 and the door 26 to 20 to 30% higher than usual. Let's do it. This operation | movement is an operation | movement which restores the opening-closing operation | movement of the doors 13 and 26 to a normal state by moving the trash clogged by the door threshold from the threshold.

In order to confirm whether the waste clogged on the thresholds of the doors 13 and 26 is moved by the operation and whether the opening and closing of the doors 13 and 26 are restored, the control panel 200 goes to step S111 of FIG. As shown, the recovery diagnosis command "door open / close diagnosis" is executed. The control panel 200 performs the opening and closing of the door 13 and the door 26 with normal torque, and whether the opening and closing operation is performed at a predetermined opening and closing time, the current of the drive motor of the door 13 and the door 26 Check if it is larger than usual. 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%, and checks whether there is no abnormality in the opening and closing time.

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

As shown in step S113 of FIG. 10, the monitor-side information processing apparatus 230 displays the determination result, the failure code, and the failure status code inputted from the control panel 200, the monitor-side communication apparatus 220, and the communication network 30. ) Is sent to the center side information processing apparatus 360 via the center side communication apparatus 320.

The monitor-side information processing apparatus 230 updates the monitor-side maintenance database 240 based on the result of the failure processing of the elevator 20 to end the operation.
