In the case of the garbage accumulation factor of the door threshold (failure factor 1), the recovery diagnosis data includes "door circuit reset + door high torque opening / closing" as the recovery command, Opening and closing diagnosis ", which is a set of two instructions, and a recovery rate x% by the recovery operation in accordance with the recovery command. When the contact failure of the switch of the door opening / closing apparatus is a factor (failure factor 2), the recovery diagnosis data includes "door circuit reset + door open / close retry" as the recovery command to the number data of the failure factor 2, Diagnosis ", which is a set of two instructions, and a recovery rate y% of the recovery operation based on the recovery command. Likewise, in the case of the failure factor 3, the recovery diagnosis data has a data structure in which the recovery diagnosis command set C and the recovery rate z% are linked to the number-of-failure data elements 3. In this way, the recovery diagnosis database 380 stores the failure code, the failure factor corresponding to the failure code, the number of the failure factors, the recovery diagnosis command set as the set of the recovery command and the recovery diagnosis, . In the present embodiment, the recovery rate y% is larger than the recovery rate x%, z%, and the recovery diagnosis command set B has a higher recovery rate than the recovery diagnosis command set A and the recovery diagnosis command set C.

Further, the remote recovery system 100 can cope with a case where a failure code related to the other parts is transmitted.

As shown in step S101 in FIG. 2 and FIG. 5, the control panel 210 of the elevator 20 determines whether or not a failure has occurred in the elevator 20. When a failure of the doors 20 and 13 of the elevator 20 occurs, for example, a door open / close failure occurs, the control panel 210 displays the failure occurrence date and time and the failure code Quot; 0001 " to the communication device 250. If no failure occurs in the elevator 20, the control panel 210 returns to the beginning of the step S101 and continues monitoring of the elevator 20.

When the failure code "0001" is input from the control panel 210, the communication device 250 transmits the failure code "0001" and the management number of the elevator 20 and the failure occurrence date and time To the communication network (30). The communication device 320 of the remote monitoring center 310 receives a failure signal transmitted from the communication device 250 through the communication network 30 as shown in step S103 of FIG. 2 and FIG. Upon receiving the fault signal, the communication device 320 outputs the fault code "0001" included in the fault signal, the control number of the elevator 20, and the fault occurrence date and time to the information processing apparatus 360. The information processing apparatus 360 stores the inputted failure code "0001", the management number of the elevator 20, and the failure occurrence date and time in the failure history data 377 of the maintenance database 370.

Then, the information processing device 360 determines whether or not the elevator 20 in which the failure has occurred can be remotely recovered, as shown in step S104 in Fig. The information processing apparatus 360 acquires the model of the elevator 20, the manufacturing date, and the manufacturing number from the elevator specification data 371 using the control number of the elevator 20, as shown in Figs. Based on the acquired specification data, the information processing apparatus 360 confirms whether or not the elevator 20 is capable of a recovery command from the remote recovery apparatus 300, a recovery operation based on the recovery diagnosis command, and a recovery diagnosis operation. The information processing apparatus 360 determines NO in step S104 of FIG. 5 when the elevator 20 is a model that can not perform the recovery operation and the recovery diagnosis operation. Then, the information processing apparatus 360 outputs a notification of the remote recovery impossibility to the remote monitoring center 310, as shown in step S127 of FIG. 2 and FIG.

When the information processing apparatus 360 corresponds to any one or more of the above (a) to (f), the information processing apparatus 360 sends the descriptor 350 to the building 10 rather than the recovery by the remote recovery system 100 It is judged to be good and it is judged as NO in the step S104 of FIG. 2 and 7, the information processing apparatus 360 outputs a notice of the remote recovery impossibility to the remote monitoring center 310. [

The information processing apparatus 360 also uses the elevator 20 management number to determine from the elevator specification data 371 and the failure history data 377 whether or not the building 10 is a building with many false alarms Check. In such a case, the information processing apparatus 360 determines that it is better to send the technician 350 to the building 10 than to the recovery by the remote recovery system 100 because the possibility of erroneous failure of the failure signal is high , It is determined NO in step S104 of FIG. Then, the information processing apparatus 360 outputs a notification of the remote recovery impossibility to the remote monitoring center 310, as shown in step S127 of FIG. 2 and FIG.

The notification of the remote repair unavailable 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. [ This informs the supervisor 334 of the remote monitoring center 310 that the elevator 20 can not be remotely recovered. When the monitor 334 confirms this display, the supervisor 334 instructs the elevator 20 to stop operating and performs the announce operation as shown in step S128 of FIG. 2 and FIG.

(m) The elevator 20 has not recently issued a fault signal based on the same fault code " 0001 ".

(n) The building (10) is not a building with a lot of malfunctioning signals.

If all the above requirements (g) to (n) are satisfied, the information processing apparatus 360 determines YES in step S104 shown in FIG. 5, and transmits, to the remote monitoring center 310 in step S105, And notifies the start of recovery. This signal is displayed on the display 331 of the remote monitoring center 310. This informs the supervisor 334 of the remote monitoring center 310 that remote recovery of the elevator 20 is started.

When the information processing apparatus 360 notifies the remote monitoring center 310 of the start of the remote recovery in step S105, the information processing apparatus 360 proceeds to step S106 shown in FIG. 5 and transmits a recovery instruction and a recovery diagnosis instruction corresponding to the failure code "0001" Select. As described above with reference to Fig. 4, the recovery diagnosis database 380 is a database linking the recovery diagnosis command set and the recovery rate to the fault-specific data 378. Hereinafter, the data configuration of the recovery diagnostic database 380 in the case where the failure code is "0001" indicating the failure relating to the doors 13, 26 will be briefly described again. In the case of the garbage accumulation factor (failure factor 1) of the door threshold, the recovery diagnosis data includes "door circuit reset + door high torque opening / closing" as a recovery command, "door opening / &Quot;, which is a set of two instructions, and a recovery rate x% by the recovery operation based on the recovery command.

As described above, the recovery rate y% is larger than the recovery rate x% and z%, and the recovery diagnosis command set B has a higher recovery rate than the recovery diagnosis command set A and the recovery diagnosis command set C, as described above.

The information processing apparatus 360 may select a command corresponding to the failure factor having the largest number of the plurality of failure factors corresponding to the failure code " 0001 " as the restoration command. Further, the information processing apparatus 360 may select a command having the highest recovery rate among a plurality of commands corresponding to the failure code " 0001 " as the restoration command. Then, the information processing device 360 selects a recovery diagnosis command set having a recovery command corresponding to the selected recovery command and a recovery command selected.

A case where the information processing apparatus 360 selects a command corresponding to a failure factor having the greatest number of failure factors among a plurality of failure factors corresponding to the failure code " 0001 " The information processing apparatus 360 refers to the recovery diagnosis database 380 and identifies a failure factor having the greatest number of cases when the failure code is " 0001 " Then, the information processing apparatus 360 performs a "door circuit reset + door high-torque opening / closing operation", which is a restoration instruction for executing a restoration operation corresponding to the accumulation of the garbage of the door threshold (failure factor 1) And a " door opening / closing diagnosis " which is a recovery diagnosis command for executing a recovery diagnosis operation corresponding to the result of the recovery operation.

For example, the ratio of the maximum number of cases to the number of the following cases (number of cases) and the ratio of the maximum recovery rate to the next recovery rate (recovery rate ratio) You may choose. Further, for example, when the previous remote recovery has failed, a different selection method may be taken from the previous time. The selection of the recovery diagnosis command set may be determined by, for example, the model, the specification, etc. of the elevator 20.

In the following description, the case where the information processing apparatus 360 selects the restoration diagnostic command set A based on the failure factor 1 having the largest number of failures corresponding to the failure code "0001" will be described.

When the recovery diagnosis command set A is selected in step S106 of FIG. 5, the information processing apparatus 360 transmits the selected recovery diagnosis command set A from the communication device 320 as shown in step S107 of FIG. 2 and FIG. do. As shown in step S108 of FIG. 2 and FIG. 5, when the communication device 250 receives the recovery diagnosis command set A from the communication device 320, the communication device 250 outputs the recovery command and the recovery diagnosis command to the control panel 210. [

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

The control panel 210 confirms whether or not there is a passenger in the car 22 from the output of a weight sensor of the car 22, a camera in the car 22, and a person sensor. The opening and closing states of the doors 13 and 26 are checked from the output of a camera, a door open / close sensor, and the like in the car 22. In addition, the control panel 210 confirms whether there is a power failure.

The control panel 210 determines YES in step S109 of Fig. 5 if the passenger is not in the elevator car 22 and the doors 13 and 26 are in the fully closed state and not in the power failure state, The process proceeds to step S110. Then, in step S110, the control panel 210 starts "remote recovery from now on" from the speaker of the communication device installed in the elevator car 22. [ The door of the elevator is opened and closed. &Quot;

The control panel 210 determines NO in step S109 of Fig. 5 when the passenger is present in the car 22, when the doors 13 and 26 are not completely closed, or when the car is in a power failure state, The process proceeds to step S125 to perform the following preparatory operation.

First, the control panel 210 confirms that the bottom 27 of the car 22 is approximately flush with the floor 12. Thereafter, the control panel 210 opens the doors 13 and 26, and initiates " remote recovery. Please descend from the elevator. &Quot; to perform an operation to lower the passenger from the elevator car 22. [ Alternatively, the control panel 210 starts " remote recovery. The passenger is lowered from the elevator car 22 by opening the doors 13 and 26 while performing an announcement such as "Please come down from the elevator." When the passenger is lowered from the elevator car 22 by such an operation, the control panel 210 makes the doors 13 and 26 in the open state fully closed. Thereafter, the process advances to step S126 in FIG. 7 to determine whether or not a passenger is present in the car 22 in the same manner as described above, whether the doors 13 and 26 are in a completely closed state, It is confirmed whether the floor 27 is approximately the same height as the floor 12 or not. The control panel 210 is configured such that the passenger is not in the elevator car 22 and the doors 13 and 26 are fully closed and the bottom 27 of the car 22 is approximately flush with the floor 12, If it is not the state, it is determined YES in step S126 of FIG. Then, the process proceeds to step S110 in Fig. 5, where the control panel 210 starts the remote recovery from the speaker of the communication device installed in the elevator car 22 from now on. The door of the elevator is opened and closed. &Quot;

If the control panel 210 determines that the elevator 20 is operating with the emergency battery in step S109 of Fig. 5, the control panel 210 waits until the electric power is restored, and if the electric power is restored, the control panel 210 goes to step S125 of Fig. 7 Go ahead. In step S125, the control panel 210 performs the same preparatory operation as described above, and proceeds to step S126 in Fig. If YES in step S126 of Fig. 7, the control panel 210 advances to step S110 in Fig. 5 to perform the remedial recovery.

On the other hand, when the control panel 210 determines NO in step S126 of Fig. 7 after the preparation operation shown in step S125 of Fig. 7, the control panel 210 proceeds to step S127 of Fig. In step S127, the control panel 210 outputs a notification of the remote recovery impossibility to the remote monitoring center 310. [

The notification of the remote repair unavailable 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. [ This informs the supervisor 334 of the remote monitoring center 310 that the elevator 20 can not be remotely recovered. Upon confirming the display, the supervisor 334 instructs the elevator 20 to stop operating and performs an announcement operation, as shown in step S128 in Fig. 2 and Fig. The supervisor 334 dispatches the technician 350 to the building 10 in the service center 340 near the building 10 by the telephone 333 as shown in Fig. 2 and step S129 in Fig. .

The control panel 210 determines YES in step S109 in FIG. 5 or step S126 in FIG. 7 and proceeds to step 110 in FIG. 5 to perform the announcement. In step S111 in FIG. 5, . At this time, since the received restoration instruction is "door circuit reset + door high torque opening / closing", which is a restoration instruction for executing restoration operation corresponding to garbage accumulation (failure factor 1) of the door threshold, the control panel 210, The door circuit of the control panel 210 is reset. This command resets the state in which the door circuit detects the state of the door 26 or the door 13 in the open (or closed) state, the half open (or semi-closed) state, Or the door 26 to be opened or closed. Next, the control panel 210 increases the torque of the drive motor of the door 13 and the door 26 by 20 to 30% higher than usual, and opens and closes the door 13 and the door 26 with a greater force than usual. This operation is an operation for moving the garbage accumulated on the threshold of the door from the threshold and returning the opening and closing operations of the doors 13 and 26 to the normal state. The control panel 210 determines whether or not the garbage accumulated on the threshold of the doors 13 and 26 has moved by the above operation and the opening and closing of the doors 13 and 26 have been restored, Quot; door open / close diagnosis " as a recovery diagnosis command. The control panel 210 opens and closes the door 13 and the door 26 with a normal torque to determine whether the opening and closing operation is performed at a predetermined opening and closing time and whether the currents of the driving motors of the door 13 and the door 26 are normal Is not larger than a predetermined value. Next, the control panel 210 opens and closes the doors 13 and 26 with the torque of the drive motor lowered by about 20% than usual, and confirms whether there is any abnormality in the opening / closing time.

Then, as shown in step S113 of Fig. 6, when the control panel 210 determines that the doors 13 and 26 have been restored to the normal state by the recovery diagnosis operation, the control panel 210 proceeds to step S114 in Fig. 2 and Fig. 6 do. In step S114, the control panel 210 outputs a determination result signal indicating that the elevator 20 has been restored. This signal is transmitted from the communication device 250 to the communication network 30. [ The transmitted determination result signal is received by the communication device 320 as shown in step S115 in Fig. 6, and the determination result is input to the information processing device 360. [ 6, the information processing apparatus 360 notifies the remote monitoring center 310, and the result is displayed on the display 331 of the remote monitoring center 310 (step S116) . The monitor 334 of the remote monitoring center 310 confirms this display and causes the elevator 20 to resume operation and announce operation as shown in step S117 of Fig. Further, the information processing apparatus 360 updates the repair database 370 and the repair diagnosis database 380 as shown in steps S118 and S119 in Fig.

On the other hand, if the result of the recovery diagnosis operation is NO in step S113 in Fig. 6, the control panel 210 proceeds to step S120 in Fig. In step S120, the control panel 210 outputs a determination result signal indicating that the recovery 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 S121 of Fig. 6, and the determination result is input to the information processing device 360. [ 6, the information processing apparatus 360 notifies the remote monitoring center 310, and the result is displayed on the display 331 of the remote monitoring center 310 (step S122) . Upon confirming the display, the supervisor 334 instructs the elevator 20 to stop operating and performs the announcing operation, as shown in step S123 of Fig. The supervisor 334 dispatches the technician 350 to the building 10 in the service center 340 near the building 10 by telephone 333 as shown in Fig. 2 and step S124 in Fig. . Further, the information processing apparatus 360 updates the repair database 370 and the repair diagnosis database 380 as shown in steps S118 and S119 in Fig.

6, the information processing apparatus 360 updates the maintenance database 370 as follows when a judgment signal indicating that the elevator 20 has been restored is input.

When the determination signal indicating that the elevator 20 has been restored as shown in step S114 in Fig. 6 is input, the information processing apparatus 360 displays the items of the recovery method of the failure history data 377 as " remote recovery & &Quot; recovery " is stored in the item of the determination result. As described above, when the communication device 320 receives the failure signal, the information processing device 360 detects the failure code " 0001 " input from the communication device 320, the management number of the elevator 20, And stores the date and time in the failure history data 377 of the maintenance database 370. Therefore, all the items of the failure history data 377 are updated by the recovery method and the restoration determination result.

In this remote recovery, the information processing apparatus 360 refers to the recovery diagnosis database 380 to determine whether or not the number of the garbage accumulated at the door threshold, which is the most frequent failure factor in the case of the failure code " 0001 "Quot; door circuit reset + door open / close retry ", which is a recovery instruction for executing the recovery operation corresponding to the failure factor 1), and " door opening / closing diagnosis ", which is a recovery diagnosis command for executing the recovery diagnosis operation corresponding to the result of this recovery operation And a recovery diagnosis and recovery diagnosis operation is executed. Therefore, when the elevator 20 is successfully recovered, the number of the failure code "0001" and the failure factor 1 (garbage accumulation at the door threshold) in the recovery diagnosis database 380 is increased by one, Increase the recovery rate. Further, the information processing device 360 increases the number of the failure factors 1 of the failure code "0001" of the failure factor-specific data 378 by one.

On the other hand, when the determination signal indicating that the recovery of the elevator 20 has failed is input as shown in step S120 in Fig. 6, the information processing apparatus 360 executes the maintenance database 370 and the recovery diagnosis database 380). When the determination signal indicating that the recovery of the elevator 20 has failed is input as shown in step S120 in Fig. 6, the information processing apparatus 360 sets the item of the recovery method of the failure history data 377 to & , &Quot; failure " is stored in the item of the recovery determination result. In addition, the number of the failure code "0001" and the failure factor 1 (garbage accumulation at the door threshold) of the recovery diagnosis database 380 is maintained, and the recovery rate is reduced by the number of failed recovery. If the recovery fails, the number of failure factors 1 of the failure code "0001" of the failure factor data 378 is not changed.

In the above description, the case where the information processing apparatus 360 has selected the recovery diagnosis command set A based on the failure factor having the greatest number of failures corresponding to the failure code "0001" has been described. When the information processing apparatus 360 selects the restoration diagnostic command set B based on the restoration rate of the restoration diagnostic command set corresponding to the failure code "0001", instead of the restoration operation of "door high-torque opening / Quot; door opening / closing retry " for performing the opening and closing operations of the doors 13 and 26 again. Other operations are the same as those in the case where the recovery diagnosis command set A is selected.

If the remote recovery of the elevator 20 is successful, the number of garbage accumulation (failure factor 1) at the door threshold, which is the largest number of failure factors in the case of the failure code "0001", increases until then. Therefore, when the remote recovery system 100 selects the recovery diagnosis command set based on the largest number of failure factors corresponding to the failure code "0001", it is determined that the failure code "0001" is input during the next remote recovery The information processing apparatus 360 selects the recovery diagnosis command set A again. When the recovery rate of the recovery diagnosis command set A is higher than the recovery rate of the recovery diagnosis command set B, the information processing apparatus 360 sets the command with the highest recovery rate among the plurality of commands corresponding to the failure code "0001" The recovery diagnosis command set A is selected.

On the other hand, if the remote recovery of the elevator 20 fails, the number of the failure factors 1 of the failure code "0001" of the failure factor data 378 is not changed, but the recovery rate of the recovery diagnosis command set A is lowered. As a result, 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 ratio of the rate of recovery becomes larger than the ratio of the number of failure factors 1 to the number of failure factors 2, the information processing apparatus 360 sets a command with the highest rate of recovery among the plurality of commands corresponding to the failure code "0001" As a return command. Therefore, when the failure code " 0001 " is input during the next remote recovery, the information processing apparatus 360 selects the recovery diagnosis command set B having the highest recovery rate. When the information processing apparatus 360 does not select the failure diagnosis command set A that failed the recovery in the last remote recovery, it is judged that the failure number 2 corresponding to the failure code " 0001 " Select Linked Recovery Diagnostic Command Set B.

When the information processing apparatus 360 has successfully recovered the elevator 20 by selecting the recovery diagnosis command set B having the highest recovery rate among the plurality of commands corresponding to the failure code "0001", the recovery diagnosis command set B . Therefore, in the following remote recovery, the recovery diagnosis command set B is selected as in the previous case. On the other hand, when recovery of the elevator 20 fails to the recovery diagnosis command set B, the recovery rate of the recovery diagnosis command set B is lowered. Then, when the recovery rate of the recovery diagnosis command set B becomes lower than the recovery rate of the recovery diagnosis command set A, the information processing apparatus 360 selects the recovery diagnosis command set A. If the information processing apparatus 360 does not select the recovery diagnosis command set B that failed in the previous remote recovery, the recovery diagnosis command set B is followed by a recovery diagnosis command with high recovery rate corresponding to the failure code " 0001 & Select command set A.

In this way, 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. Further, when the remote recovery system 100 fails in the remote recovery, the number of the failure factors remains the same, and the recovery rate of the selected recovery diagnosis command set is lowered. As a result, if the remote recovery is successful, the probability that the recovery diagnosis command set selected in the remote recovery is selected at the next remote recovery becomes high. Also, if a remote recovery fails, the set of recovery diagnostic commands selected in that remote recovery is less likely to be selected at the next remote recovery. Therefore, as the number of times of remote recovery increases, the information processing apparatus 360 can select a recovery diagnosis command set having a high possibility of recovery corresponding to the failure code from the recovery diagnosis database 380, The reliability of recovery can be improved.

Hereinabove, the case of "0001" indicating that the failure code is a failure relating to the doors 13, 26 has been described. Next, a description will be given of the case of "0002" indicating that the failure code is a failure relating to the brake. The description of the same parts as the failure code " 0001 " is omitted.

When the trouble code is 0002 indicating a trouble relating to the brake, the engineer 350 checks the area locally and the cause of outputting the trouble code "0002" is the cause of the trouble of the brake circuit of the control panel 210 ), Or other failure factors 5 and 6. Therefore, in the case of the trouble code "0002", the fault-specific data 378 includes 100 cases in which the abnormality of the brake circuit is a factor (fault 4), 50 cases in the case of the fault 5, , The data structure is the same as that of 10 cases, and the data is arranged in the order of the number of cases. In the case of restoration by the remote restoration system 100 as described above, when the recovery of the elevator 20 is successful by the restoration command, the number of the failure factors corresponding to the failure code serving as the basis of the restoration command is Is added to the number of failure factors of

As shown in FIG. 8, the recovery diagnosis database 380 is a database linking the recovery diagnosis command set and the recovery rate to the fault-specific data 378. Hereinafter, the data configuration of the recovery diagnosis database 380 in the case where the failure code is "0002" indicating a failure relating to the brake will be described. If the brake circuit abnormality is a factor (failure factor 4), the recovery diagnosis data includes the data of the number of the failure source 4, the "control circuit reset" as the recovery command, and the "brake torque diagnosis" And a recovery rate a% obtained by a recovery operation based on the recovery diagnosis command. In the case of the failure factor 5 and the failure factor 6, the recovery diagnosis data is obtained by linking the recovery diagnosis command set H, the recovery rate b%, the recovery diagnosis command set I and the recovery rate c% to the respective count data of the failure factor 5 and the failure factor 6 Data structure. In this way, the recovery diagnosis database 380 stores the failure code, the failure factor corresponding to the failure code, the number of the failure factors, the recovery diagnosis command set as the set of the recovery command and the recovery diagnosis, . In addition, b% of the recovery diagnostic command set H is the highest in the recovery rate.

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

When the failure code is " 0002 ", the information processing apparatus 360 determines whether or not the information processing apparatus 360 has executed the recovery diagnosis command " 0002 " based on the largest number of failure factors corresponding to the failure code & When the set G is selected, the information processing device 360 transmits the recovery diagnosis command set G to the control panel 210. [

When the failure code is " 0002 ", upon receipt of the recovery diagnosis command set G, the control panel 210 determines whether the elevator 20 shown in step S109 in Fig. 5 has a failure code In addition to the confirmation items in the case of " 0001 ", the brake torque diagnosis operation is executed. The brake torque diagnosis operation is an operation in which the traction machine in the drive unit 24 is not rotated by a mechanical brake and a driving force is given to the traction machine to confirm that the traction machine does not rotate by the holding force of the brake. If there is no abnormality in this operation and there is no passenger in the car 22 and the doors 13 and 26 are in the fully closed state and not in the power failure state as in the case of the failure code "0001" , The control panel 210 determines YES in step S109 of FIG. 5 and proceeds to step S110 of FIG. Then, in step S110, the control panel 210 makes an answer to the remote restoration and then proceeds to step S111 in Fig. Then, in step S111, the control panel 210 executes a control circuit reset operation.

Thereafter, the control panel 210 executes the brake torque diagnosis operation in step S112. When there is no rotation of the hoisting machine by this operation, the control panel 210 outputs a judgment result that the elevator 20 is successfully recovered. Further, when the hoisting machine has rotated, the judgment result of the failure of the recovery of the elevator 20 is output. The determination result is input from the control panel 210 to the information processing apparatus 360 through the communication apparatuses 250 and 320. [ The information processing device 360 updates the failure history data 377, the failure factor data 378, and the recovery diagnosis database 380 so that the recovery diagnosis command set having a high possibility of recovery can be selected based on the determination result .

If the elevator 20 judges that the elevator 20 is only capable of running at a low speed in the case where the hoisting machine is moved in the slightly rotating direction in the brake torque diagnosis operation of the step S112, The result of the determination may be output. In this case, the control panel 210 notifies the elevator car 20 that the elevator 20 is in a state in which it is possible to operate by restricting some functions such as high-speed driving, by the display device in the elevator car 22, And notifies the user of the elevator 20 of the display. Also, the judgment result of the partial restoration success is inputted from the control panel 210 to the information processing apparatus 360 through the communication devices 250 and 320. [ The information processing apparatus 360 updates the failure history data 377, the failure factor data 378, and the recovery diagnosis database 380 based on the determination result.

In the same manner as described above, the information processing apparatus 360 may select the recovery diagnosis command set H having the highest recovery rate corresponding to the failure code "0002" and execute the recovery operation and the recovery diagnosis operation on the control panel 210 .

When there is an abnormality in the brake torque diagnosis operation or when there is a passenger in the car 22 or when the doors 13 and 26 are not completely closed or when the car is in a power failure state, NO in step S109 of FIG. Then, the process proceeds to step S127 in Fig. 7, and the control panel 210 notifies the remote monitoring center 310 of the remote recovery impossibility.

As described above, the remote restoration system 100 is not a temporary factor such as noise, but a command from the remote restoration device 300 disposed at a place remote from the elevator 20 even when any abnormality actually occurs The elevator 20 can be restored by executing the restoration operation and the restoration diagnosis operation on the elevator 20. [ Thereby, it is possible to recover the elevator 20 in a short time without causing the engineer 350 to be dispatched locally when a failure occurs in the elevator 20, not in the case of a temporary factor such as noise, . Therefore, it is possible to improve the service of the elevator 20.

The remote recovery system 100 further includes fault history data 377, fault-specific data 378, and fault-related data 378 so as to select a recovery diagnosis command set that is more likely to be recovered at the next remote recovery based on the result of the recovery determination. , And updates the recovery diagnosis database 380. As a result, as the number of times of remote recovery increases, the information processing apparatus 360 can select a more appropriate recovery diagnosis command set corresponding to the failure code from the recovery diagnosis database 380. [ As a result, the elevator 20 can be more reliably restored. Therefore, it is possible to shorten the recovery time and improve the service of the elevator 20.

In addition, the remote recovery system 100 can resume service by restricting some functions of the elevator 20 when the elevator 20 is partially restored and is in a state in which it can operate with limited functions. Therefore, it is possible to shorten the period of stopping the service of the elevator 20 to improve the service of the elevator 20.
