Description

Remote recovery system for elevator fault

Technical Field

The present invention relates to a system for performing remote recovery when an elevator has failed.

Background

Conventionally, there is known a failure recovery support system for an elevator, including: a communication terminal connected to a control panel for controlling the driving of the elevator, and transmitting a fault signal including an error code when the elevator is in fault; and a monitoring center that receives the failure signal transmitted from the communication terminal, retrieves failure history data corresponding to the error code, and transmits the failure history data to a mobile terminal carried by a maintenance person, and the mobile terminal carried by the maintenance person analyzes the error code received from the monitoring center and displays the error code as recovery content for each failure cause (for example, see patent document 1). The failure recovery support system described in patent document 1 can know the failure content of an elevator before a maintenance worker arrives at the elevator having the failure, and can advance the recovery work immediately after arriving at the building, thereby efficiently performing the recovery work.

Further, there has been proposed a failure diagnosis system for a device, in which a server has a database that associates a check item corresponding to a type of the device and an error code, a processing content in a case where the check item matches with the error code, and a ratio of the processing performed in a case where the error code is transmitted from the model and matches with the check item, and in response to a request from a portable terminal of a service person who repairs the device, data of the check item, the processing content, and the ratio corresponding to the type of the device and the error code is transmitted to the portable terminal, and the contents of the check and the processing performed by the service person are transmitted from the portable terminal to the server, so that the check item, the processing content, and the ratio of the server corresponding to the type of the device and the error code are updated (for example, refer to patent document 2).

Further, there has been proposed a management system in which a server searches a database in which failure type information and recovery information are associated in advance, determines whether or not a failure is automatically recoverable based on the failure type information received from an image forming apparatus, and when it is determined that the failure is automatically recoverable, causes the image forming apparatus to perform automatic recovery processing, and after the automatic recovery processing, the image forming apparatus determines whether or not the automatic recovery processing is appropriate and transmits the automatic recovery processing to the server, and the server updates the database (for example, see patent document 3).

Disclosure of Invention

Problems to be solved by the invention

However, in the systems described in

patent documents

1 and 2, when the elevator has a failure, a maintenance person or a technician needs to go to the site to recover the elevator, and therefore, it takes time until the recovery, and there is a problem that the service of the elevator is reduced.

In the system described in patent document 3, whether or not automatic recovery is possible is determined based on the failure type information transmitted from the device, without considering the history of maintenance, spot inspection, repair, and the like of the device. Therefore, in the system described in patent document 3, even when it is appropriate to dispatch a technician in accordance with the history of maintenance, inspection, repair, and the like of the apparatus, automatic recovery is performed. As a result, the recovery of the device is slow, and the quality of service to the customer is degraded. Therefore, if the system described in patent document 3 is applied to an elevator, the operation service of the elevator may be reduced.

Detailed Description

Hereinafter, the remote recovery system 100 for an elevator failure according to the present embodiment will be described with reference to the drawings. As shown in fig. 1, the remote recovery system 100 has: an elevator control device 200 that controls driving of an elevator 20 disposed in a hoistway 11 of a building 10; and a remote recovery device 300 that communicates with the elevator control device 200 and causes the elevator 20 to perform a recovery operation for the failure. One or more elevators 20 that perform the restoration operation by the remote restoration device 300 may be provided. In the case where there are a plurality of elevators 20, the elevators 20 may be installed in the same building 10 or in different buildings 10.

The elevator control device 200 includes a control panel 210 for controlling the driving of the elevator 20 and a communication device 250. The control board 210 is a computer including a CPU and a memory therein. In addition, the remote recovery device 300 includes a remote monitoring center 310, an information processing device 360, a maintenance database 370, and a recovery diagnosis database 380, wherein the remote monitoring center 310 includes a communication device 320 and a monitoring tray 330. The remote monitoring center 310, the information processing device 360, the maintenance database 370, and the recovery diagnosis database 380 may be installed in the same place, or may be installed in different places and connected to each other via an internet line or the like.

The communication device 250 is connected to the control panel 210, and transmits an output from the control panel 210 to the communication network 30. Further, the communication device 250 receives the command for the control panel 210 selected by the information processing device 360 referring to the recovery diagnosis database 380 via the communication device 320 and the communication network 30, and outputs the command to the control panel 210. The communication device 320 receives a signal from the control panel 210 via the communication device 250 and the communication network 30, and outputs the signal to the information processing device 360. Further, the communication device 320 transmits the instruction for the control dial 210 selected by the information processing device 360 to the communication network 30. The

communication devices

250 and 320 may be devices that perform wireless communication or wired communication. The communication network 30 may be an internet communication network or a telephone line network.

The remote monitoring center 310 transmits and receives data to and from the information processing device 360, and a monitoring panel 330 is disposed, and the monitoring panel 330 monitors the operating condition and the failure condition of the elevator 20. The monitor panel 330 is provided with: a display 331 that displays the operation status, the failure status, the notification from the information processing device 360, and the like of the elevator 20; and a switch 332 for operating display on the display 331. Further, the monitoring board 330 is equipped with a telephone 333 that communicates with a service center 340 via the communication network 35.

The maintenance database 370 stores specifications of the elevator 20 and history data of inspection, maintenance, repair, and the like. The recovery diagnosis database 380 stores a plurality of recovery commands corresponding to the trouble codes output from the control panel 210 of the elevator 20, the number of times the recovery commands are selected, and data such as the degree of recovery of the recovery commands.

The information processing device 360 is a computer including a CPU and a memory therein. When a failure occurs in elevator 20, a failure signal output from control panel 210 is input to information processing device 360 via

communication devices

250 and 320 and communication network 30. When a failure signal is input, the information processing device 360 refers to the data in the recovery diagnosis database 380 and selects a recovery instruction and a recovery diagnosis instruction corresponding to a failure code included in the failure signal. The selected restoration command and the restoration diagnosis command are input to the control panel 210 via the

communication devices

250 and 320 and the communication network 30, and the elevator 20 is caused to perform the restoration operation and the restoration diagnosis operation.

As shown in fig. 2, the maintenance database 370 stores elevator specification data 371, inspection history data 372, maintenance work history data 373, remote spot inspection history data 374, abnormality history data 375, repair work history data 376, failure history data 377, and failure factor type data 378.

Next, the data structure of the elevator specification data 371, the inspection history data 372, the maintenance operation history data 373, the remote spot inspection history data 374, the abnormality history data 375, the repair work history data 376, the failure history data 377, and the failure factor type data 378 will be described with reference to fig. 3.

The elevator specification data 371 has a data structure in which data of a management number, a model, a manufacturing date, a manufacturing number, a name of a building to be installed, and an application for installing the building of the elevator 20 are stored. The building is set up for use in, for example, offices, general houses, restaurants, schools, and the like.

The inspection history data 372 has a data structure in which data of the management number of the elevator 20, the date and time when the technician 350 performed the inspection on the spot, the inspection item, and the inspection result are stored. The inspection is, for example, an inspection of the opened/closed state of the

doors

13 and 26 of the elevator 20 shown in fig. 1, an inspection of the stop position of each floor (a point inspection of the amount of height deviation between the floor 12 and the floor 27 of the car 22), an inspection of the rope 23, an inspection of the traveling speed, and the like. In addition, whether or not an abnormality is found as a result of the inspection, whether or not maintenance work such as cleaning is required although an abnormality is not found, or whether or not replacement of a component is required recently is input in the inspection result. In fig. 1, reference numeral 25 denotes a counterweight.

The maintenance operation history data 373 has a database structure in which the management number of the elevator 20, the date and time of the maintenance operation of the elevator 20 performed by the technician 350 on site, the maintenance operation item, and the maintenance operation result are stored. The maintenance work items include, for example, checking the operating state of the elevator 20, cleaning a door rail of the elevator 20, supplying oil to the drive device 24 shown in fig. 1, and adjusting a brake of the elevator 20. The results of the inspection, cleaning, oil supply, adjustment, and the like are input to the maintenance work results.

The remote checkup history data 374 has a data structure in which the management number of the elevator 20, the remote checkup date and time, the remote checkup item, and the remote checkup result are stored. The remote spot inspection of the elevator 20 is performed using the control panel 210 of the elevator 20 according to a preset schedule such as once a month. The control panel 210 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 mounted on the elevator 20 are used to check whether or not there is an abnormality in the operation performance (acceleration, presence or absence of abnormal sound), door opening/closing, brake, emergency battery, external communication device, and the like. The results of the checkups are stored in the remote checkup history data 374 from the information processing apparatus 360 via the

communication apparatuses

250 and 320 and the communication network 30. The remote spot check may be performed in response to an instruction from the remote monitoring center 310.

Abnormal history data 375 has a data structure in which the management number of elevator 20, the date and time of occurrence of an abnormality, abnormal items, and the result of an abnormal response are stored. The abnormality of the elevator 20 is a case where the result of the inspection, the spot inspection, the maintenance work, or the remote spot inspection performed by the technician 350 does not reach an abnormal value but changes from a normal value of the elevator 20. For example, if the result of checking that the travel speed falls within the allowable value but the deviation from the value of the previous spot check or the value of the previous check result of the elevator 20 is large, the "travel speed" is recorded in the abnormal item.

The repair work history data 376 has a data structure in which the management number of the elevator 20, the repair work date and time, the repair work item, and the repair work result are stored. The repair work is a recovery work for replacing the cable 23, the suspension roller, the brake pad, the control panel, the relay, and other replacement parts. Therefore, the names of the replacement parts such as "replace the cable", "replace the suspension roller", and "replace the brake pad" are input in the repair work project, and the items such as "end of the repair work", "need to repair again" are input in the column of the repair work result.

The failure history data 377 has a data structure in which the management number of the elevator 20, the failure occurrence date and time, the failure code, the recovery method, and the recovery determination result are stored. The trouble code is a code of a number or a combination of a number and an english alphabet output from the control panel 210 when the elevator 20 has a trouble. The types of the fault codes are, for example, about 1000. For example, when the technician 350 moves and performs inspection, spot inspection, and recovery, the content of "the technician moves" is input as an item of the recovery method. For example, when the remote restoration system 100 performs restoration, a content such as "remote restoration" is input as an item of the restoration method. When the elevator 20 is resumed and the operation is resumed, a content such as "resume" is input to the item of the resume determination result. When the recovery of the elevator 20 fails, a content such as "failure" is input to the item of the recovery determination result.

The failure factor type data 378 stores the number of failure factors corresponding to a failure code when a certain failure code is output from the control panel 210, the number of failure factors corresponding to the failure code being checked by the technician 350 and the total number of failure factors corresponding to the failure code when the recovery is performed by the remote recovery system 100. For example, if the fault code is 0001 indicating a fault in

doors

13 and 26, the result of the technician 350 performing spot check on the site is: the failure code "0001" is output mainly due to a dust jam of the door sill (failure cause 1), a switch contact failure of the door opening/closing device (failure cause 2), or another failure cause 3. Therefore, when the failure code "0001" is output, the failure factor type data has a data structure in which 100 pieces are used when the cause of the garbage jam of the door sill is the factor (failure factor 1), 50 pieces are used when the cause of the switch contact failure of the door opening and closing device is the factor (failure factor 2), and 10 pieces are used when the cause of the other failure factor 3, and the data are arranged in the order of the number of the pieces.

As shown in fig. 4, the restoration diagnosis database 380 is a database that connects a failure code, a restoration diagnosis command set that is a set of a restoration command and a restoration diagnosis command, the number of times the restoration diagnosis command set is selected, and a restoration degree indicating the degree to which the failure of the elevator 20 is restored by executing the restoration command. The restoration degree is an integer, and when the failure of the elevator 20 is restored by executing the restoration command, 1 is added to the numerical value. In addition, in the case where the recovery of the failure of the elevator 20 by executing the recovery command fails, the logarithmic value is decremented by 1. Therefore, the more the restoration of the elevator 20 is successful by executing the restoration command, the larger the value of the restoration degree. Further, the more the recovery of the elevator 20 fails by executing the recovery command, the smaller the value of the recovery degree. A high recovery degree means a high value of the recovery degree, and a low recovery degree means a low value of the recovery degree.

As an example of the restoration diagnosis database 380, a case where the failure code is "0001" indicating a failure in the

doors

13 and 26 will be described. The recovery diagnosis command set a is a set of two commands, namely "gate circuit reset + gate high torque opening/closing" as a recovery command and "gate opening/closing diagnosis" as a recovery diagnosis command, and the number of times a that the recovery diagnosis command set a is selected and the recovery degree x at which the recovery operation is performed in accordance with the recovery command of the recovery diagnosis command set a are connected and stored in the database. Similarly, the recovery diagnosis command set B is a set of two commands, namely "gate reset + gate open/close retry" as a recovery command and "gate open/close diagnosis" as a recovery diagnosis command, and the recovery diagnosis command set B is stored in the database by connecting the number of times B the recovery diagnosis command set B is selected and the recovery degree y at which the recovery operation is performed in accordance with the recovery command of the recovery diagnosis command set B. Similarly, the recovery diagnosis command set C is stored in the database by connecting the number of times C the recovery diagnosis command set C is selected and the recovery degree z at which the recovery operation is performed in accordance with the recovery command of the recovery diagnosis command set C.

The operation of the remote recovery system 100 when a failure signal is transmitted from the elevator 20 will be described below with reference to fig. 2, 5, and 6. As shown in fig. 5, the remote restoration system 100 initially operates in the learning mode, constructs a diagnostic restoration database, and shifts to the normal operation when the learning period ends. In the following description, the remote recovery operation in the case where the fault code signal "0001" related to the

gates

13 and 26 is transmitted during the learning period is first described. Next, the remote recovery operation in the case where the failure code signal "0001" is transmitted will be described with respect to the normal operation after the learning period ends. The remote recovery system 100 can also cope with a case where a fault code relating to a part other than the above-described part, for example, a control circuit incorporated in the control panel 210 is transmitted, or a case where a fault code relating to a brake in the drive device 24 or a fault code relating to another part is transmitted.

< action during learning >

As shown in fig. 2 and step S101 of 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 occurs in

doors

13 and 26 of elevator 20, for example, a failure such as a door failure, control panel 210 outputs the date and time of the failure occurrence and a failure code "0001" indicating that the failure is a failure in doors to communication device 250. If the elevator 20 is not in trouble, the control panel 210 returns to the initial step S101 to continue monitoring the elevator 20.

When the trouble code "0001" is input from the control panel 210, the communication device 250 transmits a trouble signal including the trouble code "0001", the management number of the elevator 20, and the trouble occurrence date and time to the communication network 30 as shown in step S102 in fig. 2 and 5. As shown in step S103 of fig. 2 and 5, the communication device 320 of the remote monitoring center 310 receives the fault signal transmitted from the communication device 250 via the communication network 30. Upon receiving the failure signal, communication device 320 outputs failure code "0001", the management number of elevator 20, and the failure occurrence date and time, which are included in the failure signal, to information processing device 360. The information processing device 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, as shown in step S104 of fig. 5, the information processing device 360 determines whether the elevator 20 in which the failure has occurred can be remotely restored. As shown in fig. 2 and 3, the information processing device 360 acquires the model, the manufacturing date, and the manufacturing number of the elevator 20 from the elevator specification data 371 using the management number of the elevator 20. The information processing device 360 checks whether or not the elevator 20 is of a specification capable of performing the restoration operation and the restoration diagnosis operation in accordance with the restoration command and the restoration diagnosis command from the remote restoration device 300, based on the acquired specification data. When the elevator 20 is of a type that cannot perform the remote restoration operation, the information processing device 360 outputs a signal notifying that the remote restoration is not possible to the remote monitoring center 310 as shown in step S122 in fig. 2 and 5.

As shown in fig. 2, the information processing apparatus 360 checks the following (a) to (f) with reference to the inspection history data 372, the maintenance work history data 373, the remote spot inspection history data 374, the abnormality history data 375, the repair work history data 376, and the failure history data 377.

(a) The elevator 20 is instructed to perform adjustment correction in the latest inspection.

(b) Elevator 20 has a maintenance plan at the latest or the same day, and is predicted to have a possibility of adjustment error.

(c) The remote spot inspection has a diagnosis result of an abnormality of the elevator 20.

(d) Recently an abnormality has occurred in elevator 20.

(e) The elevator 20 has recently been subjected to a repair work.

(f) Elevator 20 has recently transmitted a fault signal of the same fault code "0001".

If the above-described conditions (a) to (f) are satisfied, the information processing apparatus 360 determines that the restoration is better than the case where the technician 350 is dispatched to the building 10 by the remote restoration system 100, and determines no in step S104 in fig. 5. Then, as shown in step S122 of fig. 2 and 5, the information processing apparatus 360 outputs a notification that remote recovery is not possible to the remote monitoring center 310.

The information processing device 360 then checks whether or not the building 10 is a building in which a failure signal is frequently erroneously transmitted, based on the elevator specification data 371 and the failure history data 377 using the management number of the elevator 20. In this case, since there is a high possibility that the failure signal is erroneously transmitted, the information processing device 360 determines that it is better to dispatch the technician 350 to the building 10 than to perform recovery by the remote recovery system 100, and determines no in step S104 of fig. 5. Then, as shown in step S122 of fig. 2 and 5, the information processing apparatus 360 outputs a notification that remote recovery is not possible to the remote monitoring center 310.

As shown in fig. 2, the notification of non-remote-recoverability output from the information processing apparatus 360 to the remote monitoring center 310 is displayed on the display 331 of the remote monitoring center 310. After confirming the display, the monitoring person 334 instructs the elevator 20 to stop the operation and performs a broadcast operation as shown in step S129 in fig. 2 and 6. Then, as shown in step S130 of fig. 2 and 6, the monitoring person 334 instructs the dispatch of the technician 350 to the building 10 to the service center 340 near the building 10 via the telephone 333.

If it is determined in step S104 of fig. 5 that the elevator 20 is not remotely recoverable, the information processing device 360 stores the failure code "0001" input in step S103, 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 apparatus 360 does not update the other data of the maintenance database 370 and update the recovery diagnosis database 380, and ends the remote recovery operation.

On the other hand, in step S104 shown in fig. 5, as shown in fig. 2, the information processing apparatus 360 checks the following (g) to (n) with reference to the inspection history data 372, the maintenance job history data 373, the remote inspection history data 374, the abnormality history data 375, the repair work history data 376, and the failure history data 377.

(g) The elevator 20 is a standard capable of performing a recovery operation and a recovery diagnosis operation in response to a recovery command and a recovery diagnosis command from the remote recovery device 300.

(h) Elevator 20 has not been instructed to make an adjustment correction in the most recent inspection.

(k) Recently no abnormality has occurred in elevator 20.

(l) The elevator 20 has not recently been subjected to a repair work.

(m) the elevator 20 has not recently transmitted a fault signal of the same fault code "0001".

(n) the building 10 is not a building in which a failure signal is frequently erroneously transmitted.

When all of the above requirements (g) to (n) are satisfied, the information processing apparatus 360 determines yes in step S104 shown in fig. 5, and notifies the remote monitoring center 310 of the start of remote restoration in step S105. The signal is displayed on the display 331 of the remote monitoring center 310. Thereby, the monitoring person 334 of the remote monitoring center 310 is notified of the start of remote restoration of the elevator 20.

After notifying the remote monitoring center 310 of the start of remote restoration in step S105, the information processing apparatus 360 proceeds to step S106 shown in fig. 5 and determines whether or not the remote restoration apparatus 300 is in the learning period. This determination may be made, for example, when the number of times of remote restoration performed by the remote restoration device 300 reaches a predetermined number of times. The determination may be made based on a period of time such as the number of days after the remote restoration operation is performed by the remote restoration device 300. If it is determined that the remote recovery apparatus 300 is in the learning period, the information processing apparatus 360 proceeds to step S107 in fig. 5. In step S107, the information processing apparatus 360 selects recovery diagnosis instructions in the order of the recovery diagnosis instruction set a, the recovery diagnosis instruction set B, and the recovery diagnosis instruction set C from among a plurality of recovery diagnosis instruction sets corresponding to the trouble code "0001" stored in the diagnosis recovery database shown in fig. 4.

Hereinafter, a case where the information processing apparatus 360 selects the recovery diagnosis instruction set a corresponding to the failure code "0001" will be described.

After the restoration diagnostic instruction set a is selected in step S107 of fig. 5, the information processing apparatus 360 transmits the selected restoration diagnostic instruction set a from the communication apparatus 320 as shown in fig. 2 and step S109 of fig. 5. As shown in step S110 of fig. 2 and 5, after receiving the restoration diagnostic instruction set a from the communication device 320, the communication device 250 outputs a restoration instruction and a restoration diagnostic instruction to the control panel 210.

As shown in step S111 in fig. 5, the control panel 210 first confirms that the elevator 20 is stopped and confirms that there is no passenger in the car 22 based on the outputs of the weight sensor of the car 22, the camera in the car 22, the human sensor in the car 22, and the like. Then, after confirming that the elevator 20 is stopped and that there is no passenger in the car 22, the control panel 210 performs "now starting remote recovery from the speaker of the call device provided in the car 22. The doors of the elevator are opened and closed. "etc.

After the broadcast is completed, the control panel 210 proceeds to step S112 in fig. 5, and performs a resume operation in accordance with the resume instruction. Since the currently received restoration command is "gate reset + gate high torque open/close" which is a restoration command for causing the restoration operation to be performed corresponding to the failure code "0001", the control panel 210 first resets the gate of the control panel 210. This action is the following action: the state in which the gate circuit detects that the

door

13 or 26 cannot be opened or closed and is in the opened (or closed) state or the half-opened (or half-closed) state is reset, and the

door

13 or 26 can be opened or closed. Next, the control panel 210 increases the torque of the drive motors of the

doors

13 and 26 by 20% to 30% as compared with the normal case, and opens and closes the

doors

13 and 26 with a force larger than the normal case. This operation is an operation of moving the dust jammed in the doorsill from the doorsill to return the opening and closing operations of the

doors

13 and 26 to the normal state. The control panel 210 executes a "door open/close diagnosis" as a recovery diagnosis command to move the dust jammed on the sills of the

doors

13 and 26 by the above operation and to check whether the opening and closing of the

doors

13 and 26 are recovered, as shown in step S113 of fig. 5. The control panel 210 opens and closes the door 13 and the door 26 with a normal torque, and checks whether the opening and closing operation can be performed with a predetermined opening and closing time, and whether the current of the drive motor of the door 13 and the door 26 is not larger than normal. Next, the control panel 210 opens and closes the

doors

13 and 26 by lowering the torque of the drive motor by about 20% from the normal torque, and checks whether or not there is an abnormality in the opening and closing time.

Then, as shown in step S114 of fig. 6, when the return diagnosis operation determines that the

doors

13 and 26 have returned to the normal state, the control panel 210 proceeds to step S115 of fig. 2 and 6. In step S115, the control panel 210 outputs a determination result signal that the elevator 20 has recovered the content. The signal is transmitted from the communication device 250 to the communication network 30. As shown in step S116 of fig. 6, the communication device 320 receives the issued determination result signal, and inputs the determination result to the information processing device 360. Further, as shown in step S117 of fig. 6, the determination result is notified from the information processing apparatus 360 to the remote monitoring center 310, and the result is displayed on the display 331 of the remote monitoring center 310. After confirming the display, the monitoring person 334 of the remote monitoring center 310 causes the elevator 20 to restart the operation and perform the broadcasting operation, as shown in step S118 of fig. 6. Further, since the recovery of the elevator 20 is successful by the "gate reset + door high torque opening/closing" that is the recovery command of the recovery diagnosis command set a, the information processing device 360 adds 1 to the value x of the recovery degree of the recovery command, as shown in step S119 of fig. 6, and then proceeds to step S120 of fig. 6.

In step S120 of fig. 6, the information processing apparatus 360 saves "remote recovery" in the item of the recovery method of the failure history data 377 of the maintenance database 370, and saves "recovery" in the item of the recovery determination result. As described above, when the communication device 320 receives the failure signal, the information processing device 360 stores the failure code "0001" input from the communication device 320, 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. Therefore, all items of the failure history data 377 for maintaining the database are updated by storing the recovery method and the recovery determination result of this time.

After updating the maintenance database 370 in step S120, the information processing apparatus 360 proceeds to step S121 in fig. 6 to update the recovery diagnosis database 380.

As described above, in step S121 of fig. 6, the information processing device 360 adds 1 to the number of times a that the recovery diagnosis instruction set a is selected, and saves the recovery degree x obtained by adding 1 to the recovery diagnosis database 380 in step S119, thereby updating the recovery diagnosis database 380.

On the other hand, if the result of the resumption diagnosis operation in step S114 of fig. 6 is determined as "no", the control panel 210 proceeds to step S123 of fig. 6. In step S123, the control panel 210 outputs a determination result signal indicating that the recovery of the elevator 20 has failed. The signal is transmitted from the communication device 250 to the communication network 30. As shown in step S124 of fig. 6, the communication device 320 receives the issued determination result signal, and inputs the determination result to the information processing device 360. Further, as shown in step S125 of fig. 6, the determination result is notified from the information processing apparatus 360 to the remote monitoring center 310, and the result is displayed on the display 331 of the remote monitoring center 310. After confirming the display, the monitoring person 334 instructs the elevator 20 to stop the operation and performs a broadcast operation as shown in step S126 in fig. 6. Further, as shown in step S127 of fig. 2 and 6, the monitoring person 334 instructs the service center 340 near the building 10 to dispatch the technician 350 to the building 10 via the telephone 333. Further, since the recovery of the elevator 20 is failed by the "gate reset + door high torque opening/closing" that is the recovery command of the recovery diagnosis command set a, the information processing device 360 decreases the value x of the recovery degree of the recovery command by 1 as shown in step S128 of fig. 6, and then proceeds to step S120 of fig. 6.

When a determination signal indicating that the elevator 20 has failed in recovery as shown in step S124 of fig. 6 is input, the information processing device 360 stores "remote recovery" in the item of the recovery method of the failure history data 377 and "failure" in the item of the recovery determination result. As described above, when the communication device 320 receives the failure signal, the information processing device 360 stores the failure code "0001" input from the communication device 320, 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. Therefore, all the items of the failure history data 377 of the maintenance database 370 are updated by storing the recovery method and the recovery determination result of this time.

After updating the maintenance database 370 in step S120, the information processing apparatus 360 proceeds to step S121 of fig. 6 to update the recovery diagnosis database 380.

As described above, in step S121 of fig. 6, the information processing device 360 adds 1 to the number of times a that the recovery diagnosis instruction set a is selected, and saves the recovery degree x obtained by subtracting 1 in step S128 to the recovery diagnosis database 380 to update the recovery diagnosis database 380.

In the case where the remote restoring apparatus 300 is in the learning period, the control panel 210 outputs a failure signal including the next failure code "0001". The failure signal is output to the information processing device 360 via the

communication devices

250 and 320 and the communication network 30. When a failure signal is input, the information processing apparatus 360 selects the next recovery diagnosis instruction set B of the previous recovery diagnosis instruction set a in step S107 in fig. 5. When the recovery diagnosis command set B is selected, a difference is that a recovery operation of "door opening/closing retry" in which the

doors

13 and 26 are opened and closed again with a normal torque is performed instead of the recovery operation of "door high torque opening/closing" in the recovery diagnosis command set a. The other actions are the same as in the case where the recovery diagnosis instruction set a is selected.

When the recovery of the elevator 20 is successful by the "gate reset + door opening/closing retry" that is the recovery command of the recovery diagnosis command set B, the information processing device 360 increments the value of the recovery degree of the recovery command by 1 as shown in step S119 in fig. 6. Then, the information processing apparatus 360 proceeds to step S120 of fig. 6, and updates the maintenance database 370. Subsequently, the information processing apparatus 360 proceeds to step S121 of fig. 6, and updates the restoration diagnosis database 380. The information processing apparatus 360 adds 1 to the number of times B that the recovery diagnosis instruction set B is selected in step S121 of fig. 6, and saves the recovery degree y after the addition of 1 in step S119 in the recovery diagnosis database 380 to update the recovery diagnosis database 380.

When the recovery of the elevator 20 fails due to "gate reset + door open/close retry" which is a recovery command of the recovery diagnosis command set B, the information processing device 360 decreases the value y of the recovery degree of the recovery command by 1 as shown in step S128 of fig. 6. Then, the information processing apparatus 360 proceeds to step S120 of fig. 6, and updates the maintenance database 370. After that, the information processing apparatus 360 proceeds to step S121 of fig. 6, and updates the recovery diagnosis database 380. The information processing apparatus 360 adds 1 to the number of times B that the recovery diagnosis instruction set B is selected in step S121 of fig. 6, and saves the recovery degree y obtained by subtracting 1 from the value in step S128 to the recovery diagnosis database 380 to update the recovery diagnosis database 380.

In this way, when the remote recovery apparatus 300 is in the learning period, the control panel 210 outputs a failure signal including the next failure code "0001". The failure signal is input to the information processing device 360 via the

communication devices

250 and 320 and the communication network 30. When a failure signal is input, information processing apparatus 360 selects recovery diagnosis command set a, recovery diagnosis command set B, and recovery diagnosis command set C in order in step S107 in fig. 5, and causes control panel 210 to perform a remote recovery operation. The information processing apparatus 360 adds 1 to the number of times of selection of the selected restoration diagnosis instruction set, and executes the remote restoration operation. The information processing apparatus 360 repeatedly performs the following actions: and if the remote recovery is successful, adding 1 to the recovery degree of the recovery instructions contained in the remote recovery diagnosis instruction set, and if the recovery is failed, subtracting 1 from the recovery degree of the recovery instructions contained in the remote recovery diagnosis instruction set.

If this restoration operation is repeated, the value of the degree of restoration of the restoration diagnostic instruction set including the restoration instruction having a high success rate of restoration becomes high. Further, if the recovery diagnosis operation is repeated, the value of the recovery degree of the recovery diagnosis instruction set including the recovery instruction having a low success rate of recovery becomes low. For example, in the restoration diagnosis database 380, values are stored such that the number of selections of the restoration diagnosis instruction set a is 1000 times and the degree of restoration x is 500, the number of selections of the restoration diagnosis instruction set B is 1000 times and the degree of restoration y is 300, the number of selections of the restoration diagnosis instruction set C is 1000 times and the degree of restoration z is 150. In the learning period, when the fault code is "0001", the recovery diagnosis instruction set a, the recovery diagnosis instruction set B, and the recovery diagnosis instruction set C are executed in this order. Therefore, when the learning period ends, the number of selections of each recovery diagnosis instruction set is substantially the same value.

Then, after performing the remote recovery a predetermined number of times and determining that sufficient data is stored in the recovery diagnosis database 380, the information processing apparatus 360 determines that the learning period of the remote recovery apparatus 300 is ended.

< action after end of learning period >

Next, after the end of the learning period, the remote recovery apparatus 300 executes a normal operation as described below. Note that the same operation as that in the learning period described above will not be described.

In the normal operation after the end of the learning period, the information processing apparatus 360 determines in step S106 of fig. 5 whether or not it is a learning period, and proceeds to step S108 of fig. 5. In step S108, the information processing apparatus 360 selects a restoration diagnostic instruction set having a high restoration degree in the restoration diagnostic database 380 shown in fig. 4. Assume that, as in the example shown above, values of the recovery diagnostic instruction set a of which the number of selections is 1000 and the recovery degree x is 500, the recovery diagnostic instruction set B of which the number of selections is 1000 and the recovery degree y is 300, the recovery diagnostic instruction set C of which the number of selections is 1000 and the recovery degree z is 150 are stored in the recovery diagnostic database 380. The information processing apparatus 360 selects the restoration diagnosis instruction set a having the largest value of the restoration degree from the restoration diagnosis database 380, and proceeds to step S109 in fig. 5. In step S109, the information processing apparatus 360 transmits the restoration instruction and the restoration diagnostic instruction included in the restoration diagnostic instruction set a to the control panel 210. The control panel 210 executes the recovery operation and the recovery diagnosis operation based on the received recovery command as shown in steps S112 and S113 of fig. 5.

Then, when the recovery of the elevator 20 is successful by the "gate reset + door high torque opening/closing" that is the recovery command of the recovery diagnosis command set a, the information processing device 360 increments the value of the recovery degree of the recovery command by 1 as shown in step S119 in fig. 6, and proceeds to step S121 in fig. 6, as in the learning period. In step S121, the information processing apparatus 360 adds 1 to the number of times a that the recovery diagnosis instruction set a is selected, and saves the recovery degree x after the addition of 1 in step S119 into the recovery diagnosis database 380 to update the recovery diagnosis database 380.

In addition, when the recovery of the elevator 20 is failed by the recovery command of the recovery diagnosis command set a, the information processing device 360 decreases the value x of the recovery degree of the recovery command by 1 as shown in step S128 of fig. 6, and then proceeds to step S121 of fig. 6, as in the learning period. In step S121, the information processing apparatus 360 updates the restoration diagnosis database 380 by adding 1 to the number a of times the restoration diagnosis instruction set a is selected, and saving the restoration degree x obtained by subtracting 1 from the value in step S128 to the restoration diagnosis database 380.

In this way, after the learning period of the remote restoration device 300 is ended, the information processing device 360, after receiving the failure code "0001", selects a restoration diagnosis instruction set having a high restoration degree among the plurality of restoration diagnosis instruction sets with reference to the restoration diagnosis database 380 shown in fig. 4. Then, the information processing device 360 causes the control panel 210 to execute the recovery operation and the recovery diagnosis operation. When the recovery of the elevator 20 is successful, the recovery degree of the recovery command included in the recovery diagnosis command set is increased by 1. In addition, in the case of failure of recovery, the degree of recovery included in the recovery diagnostic instruction set is reduced by 1. Thus, the restoration diagnostic instruction set including the restoration instruction having a high degree of restoration of the elevator 20 is selected more. In addition, the number of times of selecting the recovery diagnosis instruction set including the recovery instruction having a high degree of failure in recovery of the elevator 20 is reduced. Therefore, in the case where the failure code "0001" is input, the degree of remote restoration success is made greater.

In the case where the recovery diagnosis instruction set a having the highest recovery degree is selected when the trouble code "0001" is received but recovery by remote recovery fails, the recovery diagnosis instruction set B having the second highest recovery degree may be selected to execute the recovery operation or the recovery diagnosis operation without selecting the recovery diagnosis instruction set a when the trouble code "0001" is received next time. In this case, if the recovery of the elevator 20 is successful, the recovery degree of the recovery command included in the recovery diagnosis command set B is increased by 1. In addition, in the case of failure of recovery, the degree of recovery included in the recovery diagnosis instruction set B is reduced by 1. Thus, the restoration diagnostic instruction set including the restoration instruction having a high restoration degree of the elevator 20 is selected more. In addition, the number of times of selecting the recovery diagnosis command set including the recovery command having a high degree of failure in recovery of the elevator 20 is reduced. Therefore, in the case where the failure code "0001" is input, the degree of remote restoration success is made greater.

Next, a case where the trouble code and the elevator status code are output from the control panel 210 together will be described with reference to fig. 7 to 11. The same matters as those described above with reference to fig. 1 to 6 will not be described.

As shown in fig. 7, when the elevator 20 has a failure, the elevator status code is output together with the failure code from the control panel 210. The elevator status code is a code made up of words indicating the status of the elevator 20. The elevator status code includes codes such as "door cannot be opened" and "door cannot be closed". As regards the elevator status code, for example, an elevator status code is output together with a fault code. In addition, as for the elevator status code, for example, a plurality of elevator status codes are output together with one fault code.

As shown in fig. 8, the failure history data 377 has a data structure in which the management number of the elevator 20, the failure occurrence date and time, the failure code, the elevator status code, the recovery method, and the recovery determination result are stored. For example, when the technician 350 moves and performs inspection, spot inspection, and recovery, the content of "the technician moves" is input as an item of the recovery method. When the remote restoration system 100 performs the restoration, a content such as "remote restoration" is input as an item of the restoration method. When the elevator 20 is resumed and the operation is resumed, a content such as "resume" is input to the item of the resume determination result. In addition, when the recovery of the elevator 20 fails, the item of the recovery determination result is input with the content of "failure". The elevator specification data 371, the inspection history data 372, the maintenance work history data 373, the remote spot inspection history data 374, the abnormality history data 375, the repair work history data 376, and the failure history data 377 of the maintenance database 370 are the same as those described above with reference to fig. 2, and therefore, illustration and description thereof are omitted in fig. 8.

As shown in fig. 8, the failure factor type data 378 stores the number of times a certain failure code and a certain elevator status code are received when the failure code and the elevator status code are output from the control panel 210, and the number of failure factors corresponding to the failure code and the elevator status code based on the results of inspection and spot check performed by the technician 350 when going to the scene. Note that the data structures other than the failure history data 377 and the failure factor type data 378 of the maintenance database 370 are the same as those described with reference to fig. 3, and therefore, the illustration and description thereof are omitted.

For example, when the received a-time failure code is 0001 indicating a failure in the

doors

13 and 26 and the elevator status code is "door cannot be opened", the result of the technician 350 performing spot inspection on the site is: the main causes of outputting the failure code "0001" and the elevator status code "door cannot be opened" are a door sill garbage jam (failure cause 1), a switch contact failure of a door opening/closing device (failure cause 2), and another failure cause 3. Therefore, when the trouble code "0001" and the elevator status code "door cannot be opened" are output, the failure factor type data 378 has a data structure in which 100 pieces are used as the factor of the door sill dust clogging (failure factor 1), 50 pieces are used as the factor of the door opening/closing device switch contact failure (failure factor 2), and 10 pieces are used as the other failure factor 3, and the data are arranged in order of the number of these pieces.

Similarly, when the B-time failure code is 0001 indicating a failure related to the

doors

13 and 26 and the elevator status code is "door not closed", the failure code "0001" and the elevator status code "door not closed" are output as the cause of a door sill garbage jam (failure cause 1), a door open/close device switch contact failure (failure cause 2), or another failure cause 3. Therefore, when the failure code "0001" and the elevator status code "door cannot be closed" are output, the failure factor type data 378 has a data structure in which 100 pieces are used as the cause of the garbage clogging of the door sill (failure factor 1), 50 pieces are used as the cause of the switch contact failure of the door opening/closing device (failure factor 2), and 10 pieces are used as the other failure factor 3, and the data is arranged in order of the number of these pieces.

The same applies to the case where two elevator status codes of "door not openable" and "door not closable" are output together with the failure code "0001".

As shown in fig. 9, the restoration diagnosis database 380 is a database that connects a restoration diagnosis command set, which is a set of a trouble code, an elevator status code, a restoration command, and a restoration diagnosis command, the number of times the restoration diagnosis command set is selected, and a restoration degree indicating the degree of restoration of the trouble of the elevator 20 by execution of the restoration command. The restoration degree is an integer, and when the failure of the elevator 20 is restored by executing the restoration command, 1 is added to the value of the restoration degree. When the failure of the elevator 20 is not recovered by executing the recovery command, the numerical value of the recovery degree is reduced by 1. Therefore, the more the restoration of the elevator 20 is successful by executing the restoration command, the larger the value of the restoration degree. Further, the more the recovery of the elevator 20 fails by executing the recovery command, the smaller the value of the recovery degree. A high recovery degree means a high value of the recovery degree, and a low recovery degree means a low value of the recovery degree.

As an example of the restoration diagnosis database 380, a case will be described in which the failure code is "0001" indicating a failure in the

doors

13 and 26, and the elevator status code is "the door cannot be opened". The recovery diagnosis command set a is a set of two commands, namely "gate circuit reset + gate high torque opening/closing" as a recovery command and "gate opening/closing diagnosis" as a recovery diagnosis command, and is stored in the database by connecting the number of times a the recovery diagnosis command set a is selected and the recovery degree p of recovery operation according to the recovery command of the recovery diagnosis command set a. Similarly, the recovery diagnosis command set B is a set of two commands, namely "gate reset + gate open/close retry" as a recovery command and "gate open/close diagnosis" as a recovery diagnosis command, and is stored in the database by connecting the number of times B the recovery diagnosis command set B is selected and the recovery degree q at which the recovery operation is performed in accordance with the recovery command of the recovery diagnosis command set B. Similarly, the restoration diagnosis command set C is stored in the database so as to connect the number of times C the restoration diagnosis command set C is selected and the restoration degree r at which the restoration operation is performed in accordance with the restoration command of the restoration diagnosis command set C.

As shown in fig. 10, even when the trouble code is "0001" and the elevator status code is "door not closed", the item of the elevator status code is "door not closed" in the structure of the recovery diagnosis database 380, and the recovery degrees are u, v, and w. The other structure is the same as the case where the elevator status code described with reference to fig. 9 is "door-unopened".

The operation of the remote restoration system 100 according to the present embodiment is different from the operation of the embodiment described above with reference to fig. 1 to 6 in that one or more elevator status codes are output from the control panel 210 together with the trouble code as shown in step S202 in fig. 11. Further, as shown in step S203 in fig. 11, the output fault code and elevator status code are input to the information processing device 360 via the

communication devices

250 and 320 and the communication network 30, which is different from the embodiment described above with reference to fig. 1 to 6. Further, the difference from the embodiment described with reference to fig. 1 to 6 is that in steps S207 and S208 in fig. 11, the information processing device 360 selects a restoration diagnosis instruction set based on the trouble code and the elevator status code. Otherwise the same as the embodiment described above with reference to fig. 1 to 6.

In step S106 in fig. 11, when the remote restoration device 300 is in the learning period, the information processing device 360 executes the restoration diagnosis command set a, the restoration diagnosis command set B, and the restoration diagnosis command set C in this order with reference to the restoration diagnosis database 380 shown in fig. 9 or fig. 10 based on the input trouble code and the elevator status code, as shown in step S207 in fig. 6. Then, if the recovery is successful, 1 is added to the degree of recovery of the recovery instruction (step S119 in fig. 12), and if the recovery fails, 1 is subtracted from the degree of recovery of the recovery instruction (step S128 in fig. 12), and the recovery diagnosis database 380 is updated. After the remote restoration is performed a predetermined number of times or a predetermined period of time has elapsed and the learning period of the remote restoration device 300 is ended, the information processing device 360 selects a restoration diagnosis command set including a restoration command having the highest degree of restoration among a plurality of restoration diagnosis command sets corresponding to the trouble code and the elevator status code, as shown in step S208 in fig. 11. Also, if the recovery is successful, 1 is added to the degree of recovery of the recovery instruction (step S119 in fig. 12), and if the recovery fails, 1 is subtracted from the degree of recovery of the recovery instruction (step S128 in fig. 12), and then the recovery diagnosis database 380 is updated.

The remote restoring system 100 of the present embodiment is also similar to the above-described embodiments, and therefore, a larger number of restoration diagnosis command sets including a restoration command having a high degree of restoration of the elevator 20 are selected, and the number of times of selecting a restoration diagnosis command set including a restoration command having a high degree of failure of restoration of the elevator 20 is reduced. Therefore, even when the elevator status code is input together with the trouble code "0001", the degree of success of the remote restoration is made larger.

When two elevator state codes, i.e., "the failure code" 0001 "and" the door cannot be opened "and" the door cannot be closed ", are output from the control panel 210, the information processing device 360 refers to the failure factor type data 378 shown in fig. 8, and selects a restoration diagnosis instruction set based on the failure code" 0001 "and the elevator state code that has been received with the failure code" 0001 "a large number of times, as described above.

As described above, the remote restoration system 100 can perform the restoration of the elevator 20 by causing the elevator 20 to perform the restoration operation and the restoration diagnosis operation in response to a command from the remote restoration device 300 disposed at a location remote from the elevator 20 when various failures occur in the elevator 20. This enables the elevator 20 to be recovered in a short time without requiring the technician 350 to move to the site when the elevator 20 has failed, thereby improving the operation service of the elevator 20.

Further, the remote restoration system 100 updates the restoration diagnosis database 380 according to the restoration determination result, so that a restoration diagnosis instruction set with a higher restoration degree can be selected at the next remote restoration. As the number of remote recoveries increases, the information processing device 360 can thereby select a more appropriate recovery diagnosis instruction set corresponding to the trouble code or corresponding to the trouble code and the elevator status code from the recovery diagnosis database 380. This enables the elevator 20 to be restored more reliably, and the time taken for restoration can be shortened, thereby improving the operation service of the elevator 20.

The present invention is not limited to the embodiments described above, and includes all changes and modifications that do not depart from the technical scope and spirit of the present invention defined by the claims.
