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, the following techniques are proposed: when it is diagnosed by an abnormality diagnostic device that diagnoses a running state of an elevator that there is an abnormality in the elevator, a control constant of the elevator is changed to suppress the running performance of the elevator and cause the elevator to run without stopping (see, for example, patent document 2).

Disclosure of Invention
Problems to be solved by the invention
However, when the elevator is recovered when an abnormality or a failure occurs, it is necessary to reflect the operation of the elevator by the customer. For example, there are the following cases: in a period in which the manager of the elevator is resident as in the daytime on weekdays, the manager having the elevator operation authority can perform the recovery operation in consideration of the situation of the elevator in which the failure has occurred. In contrast, in a period in which the manager of the elevator is not resident and the elevator hardly operates as in a holiday or late at night, the elevator can sometimes be recovered in a short time by remote operation. In addition, as in a commercial building, in a period in which many people use an elevator during daytime of a holiday, it is sometimes desirable to temporarily stop the operation of the elevator and to perform recovery by a professional technician.
However, in the failure recovery support system described in patent document 1, a technician is caused to move regardless of the elevator operation of the customer. In addition, in the elevator described in patent document 2, the elevator is automatically recovered regardless of the elevator operation of the customer. Therefore, in the conventional techniques described in patent documents 1 and 2, it is difficult to recover from an elevator failure based on the elevator operation situation of the customer.
Therefore, an object of the present invention is to recover from an elevator failure based on the elevator operation of a customer.

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; 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; and a customer terminal 400 in communication with the remote restoring apparatus 300. 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. The remote recovery device 300 further includes a remote monitoring center 310, an information processing device 360, a maintenance database 370, a recovery diagnosis database 380, and a recovery operation condition database 390, wherein the remote monitoring center 310 includes a communication device 320 and a monitoring panel 330. The remote monitoring center 310, the information processing device 360, the maintenance database 370, the recovery diagnosis database 380, and the recovery operation condition database 390 may be installed in the same place or may be installed in different places and connected to each other through 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 is provided with a monitoring panel 330, and the monitoring panel 330 transmits and receives data to and from the information processing device 360 and monitors the operation 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, operation, and the like. The restoration diagnosis database 380 stores data such as a plurality of failure factors, the number of failure factors, and the restoration rate corresponding to the failure code output from the control panel 210 of the elevator 20. The recovery operation condition database 390 stores the execution conditions of the recovery operation of the elevator 20.
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 information processing apparatus 360 determines whether or not the recovery command selected with reference to the recovery operation condition database 390 can be executed. Then, in a case where the selected restoration instruction can be executed, the selected restoration instruction and restoration diagnostic instruction are transmitted to the control panel 210 via the communication devices 250, 320 and the communication network 30. The control panel 210 causes the elevator 20 to execute the restoration operation and the restoration diagnosis operation based on the received restoration command and the restoration diagnosis command.
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, operation history data 378, and failure factor type data 379.
Hereinafter, 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, the operation history data 378, and the failure factor type data 379 will be described with reference to fig. 3 and 4.
The elevator specification data 371 has a data structure in which a management number, a model, a manufacturing date, a manufacturing number, a name of a building to be installed, and maintenance contractor data of the elevator 20 are stored. The maintenance contractor of the elevator 20 is, for example, the name of the owner of the building or the name of the maintenance management company.
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 14 denotes a landing button, reference numeral 28 denotes a destination floor button, and 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, a failure code, failure location information, failure content, a recovery method, and a 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. The failure location information stores the name of a location where a failure has occurred, such as "car door". The contents of the failure include, for example, states of failure such as "open impossible" and "close impossible". 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 date and time immediately before occurrence of a failure and the operating state of each part of elevator 20 are stored in operation history data 378. For example, the operation date and time immediately before the failure, the position, the moving direction, the speed, the open/close states of the doors 13 and 26, and the like of the car 22 at that time are stored.
The failure factor type data 379 stores the total number of 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 the failure factors corresponding to the failure code being checked by the technician 350, and the number of the 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 379 has a data structure in which 100 pieces are used when the door sill is clogged with dust (failure factor 1), 50 pieces are used when the door opening/closing device is in contact failure (failure factor 2), and 10 pieces are used when the other failure factor 3 is, and the number of data pieces is arranged in order of increasing or decreasing. When the recovery of the elevator 20 is successful by the recovery command in the case of recovery by the remote recovery system 100, the number of failure causes corresponding to the failure code that is the basis of the recovery command is added to the number of failure causes of the entire system.
Further, in the case of fault code "0002", the results of the spot check performed by technician 350 on site are: the cause of the output of the failure code "0002" is a failure in the operation of the control circuit in the control panel 210 (failure cause 4), a failure in the operation of the CPU mounted on the control board (failure cause 5), or another failure cause 6. In the case of the failure code "0002", the failure factor type data 379 has a data structure in which the failure of the control circuit is a factor (failure factor 4), 100 pieces are used, the failure of the CPU is a factor (failure factor 5), 50 pieces are used, and the other failure factors 6 are 10 pieces, and the number of pieces of data is arranged in order of the number of pieces.
As shown in fig. 5, the restoration diagnosis database 380 stores a restoration diagnosis command set, which is a set of a restoration command and a restoration diagnosis command, and a restoration rate (%) which is a rate at which the elevator 20 is restored to the failure by executing the restoration command, in order from the number of causes of failure in the failure cause type data 379. The recovery diagnosis database 380 is a database that connects the recovery diagnosis instruction set, the recovery rate, and the recovery action section with the failure primary cause category data 379 described above.
Hereinafter, a data structure of the recovery diagnosis database 380 in the case where the failure code shown by reference numeral 381 in fig. 5 is "0001" indicating a failure in the doors 13 and 26 will be described. When the door sill is a cause of the dust jam (cause of failure 1), the recovery diagnosis data is a data structure in which a recovery diagnosis command set a, which is a set of two commands of "gate reset + gate high torque opening/closing" as a recovery command and "gate opening/closing diagnosis" as a recovery diagnosis command, a recovery rate a% of recovery operation according to the recovery command, and the number data of the cause of failure 1 are connected to the recovery operation classification "a". Here, the restoration operation distinction is a distinction in which the restoration diagnostic command set is distinguished from the outside depending on whether or not the movement of the elevator 20 is accompanied in the restoration operation. For example, as in the recovery diagnosis command set a, the opening and closing operations of the doors 13 and 26 are accompanied by the recovery operation ("door high torque opening and closing"), and the recovery operation is classified as "a". In the restoration operation, as in the control circuit reset and the CPU reset described later, the restoration operation section of the restoration diagnosis command set that does not accompany the operation of the elevator 20 is "B" when viewed from the outside. When the failure of the switch contact of the door opening/closing device is a factor (failure factor 2), the recovery diagnosis data is a data structure in which a recovery diagnosis command set B, which is a set of two commands of "gate reset + retry of door opening/closing" and "door opening/closing diagnosis" as a recovery diagnosis command, a recovery rate B% at which a recovery operation is performed in accordance with the recovery command, and a recovery operation classification "a" are connected to the number data of the failure factor 2. Similarly, in the case of the failure factor 3, the recovery diagnosis data is a data structure in which the recovery diagnosis command set C, the recovery rate C%, and the recovery operation classification "a" are connected to the number data of the failure factor 3. In this way, the restoration diagnosis database 380 stores the failure code, the failure cause corresponding to the failure code, the number of the failure causes, the restoration diagnosis command set, which is a set of the restoration command and the restoration diagnosis, the restoration rate, and the restoration operation in the database in a manner of being associated with each other. In the present embodiment, the recovery rate B% is a numerical value larger than the recovery rates a% and C%, and the recovery rate of the recovery diagnosis command set B is higher than the recovery rates of the recovery diagnosis command set a and the recovery diagnosis command set C.
Next, a data structure of the recovery diagnosis database 380 in the case where the failure code indicated by reference numeral 382 in fig. 5 is "0002" indicating a failure related to the control circuit will be described. When the operation of the control circuit is defective (failure factor 4), the recovery diagnosis data is a data structure in which a recovery diagnosis command set D, which is a set of two commands of "control circuit reset" as a recovery command, and "operation diagnosis on each floor" as a recovery diagnosis command, and a recovery rate D% at which the recovery operation is performed in accordance with the recovery command and a recovery operation classification "B" are connected to the number data of the failure factor 4. As described above, the recovery command of "control circuit reset" included in the recovery diagnosis command set D does not accompany the operation of the elevator 20 from the outside during the recovery operation, and therefore "B" is stored in the recovery operation classification of the recovery diagnosis command set D. When the CPU has failed to operate (failure factor 5), the recovery diagnosis data has a data structure in which a recovery diagnosis command set E, which is a set of two commands "CPU reset" as a recovery command, "operation diagnosis on each floor" as a recovery diagnosis command, a recovery rate E% at which the recovery operation is performed in accordance with the recovery command, and a recovery operation classification "B" are connected to the number data of the failure factor 5. The recovery command of "CPU reset" does not accompany the operation of the elevator 20 when viewed from the outside during the recovery operation, and therefore "B" is stored in the recovery operation section of the recovery diagnosis command set E. Similarly, in the case of the failure factor 6, the restoration diagnostic data is a data structure in which the restoration diagnostic command set F, the restoration rate F%, and the restoration operation distinction "B" are connected to the number data of the failure factor 6. In addition, regarding the recovery rate, E% of the recovery diagnosis instruction set E is the highest.
Next, the recovery operation condition database 390 will be described. As shown in fig. 6, the recovery operation condition database 390 stores the management number of the elevator 20, the model, the date of manufacture, data of the specifications of the elevator 20 such as the installation name of the building, the maintenance contractor, and the like, and an operation condition time table 391 of the recovery operation of the elevator 20.
The action condition schedule 391 shown in fig. 6 specifies a distinction between remote restoration actions agreed upon for execution with customers for each week and period of the elevator 20 of management number "123456". The symbol "o" in the table indicates agreement with the customer for execution in the remote recovery operation section, the symbol "x" indicates agreement with the customer for execution failure, and the symbol "Δ" indicates execution of the recovery operation in accordance with the judgment of the customer.
As shown in operation condition schedule 391 of fig. 6, in elevator 20 of management number "123456", agreement is made with customers between 0 o 'clock in late night and 6 o' clock in morning regardless of the week, and both of remote restoration operation in which a distinction "a" is made with the motion of elevator 20 in restoration operation and remote restoration operation in which a distinction "B" is made without the motion of elevator 20 in restoration operation are performed. Therefore, in the elevator 20, regardless of the week, the remote restoration operation for distinguishing "a" and the remote restoration operation for distinguishing "B" can be performed in the morning.
As shown in the operation condition schedule 391 of fig. 6, the remote restoration operation with the distinction "a" of the movement of the elevator 20 in the restoration operation is executed without agreement with the customer after 6 am on saturday or sunday, but the remote restoration operation with the distinction "B" of the movement of the elevator 20 in the restoration operation is executed without agreement with the customer. Therefore, on saturday, 6 am on sunday, and thereafter, the remote restoration action distinguishing "a" cannot be performed, but the remote restoration action distinguishing "B" can be performed.
As shown in operation condition schedule 391 of fig. 6, with respect to elevator 20, after 6 am on weekdays, the customer agrees to perform a recovery operation with a distinction "a" that accompanies the movement of elevator 20 in the recovery operation, and the customer agrees to perform a remote recovery operation with no distinction "B" that accompanies the movement of elevator 20 in the recovery operation. Therefore, after 6 am on sunday, the recovery action distinguishing "a" can be performed by the customer, and the recovery action distinguishing "B" can be performed remotely.
The recovery operation condition database 390 shown in fig. 7 includes an operation condition schedule 393, and the operation condition schedule 393 represents the remote recovery operation distinction agreed upon for execution between the time slots of the specific day of the elevator 20 of the management number "123456" described earlier with reference to fig. 6 and the customer. As shown in the action condition schedule 393 of fig. 7, on a particular day, regardless of the time period, an agreement is reached between customers regarding the remote recovery actions of the distinction "a", the distinction "B", and any distinction of the remote recovery actions can be performed.
The recovery operation condition database 390 shown in fig. 8 includes an operation condition schedule 395, and the operation condition schedule 395 indicates the respective weeks and periods of the elevator 20 corresponding to the management number "789012" different from the management number "123456" described above with reference to fig. 6 and 7, and the remote recovery operation agreed upon for the customer with respect to the execution. As shown in the operation condition schedule 395 of fig. 8, the remote restoration operation with the distinction "a" of the movement of the elevator 20 in the restoration operation is executed without agreement with the customer after 6 am on weekdays, but the remote restoration operation with the distinction "B" of the movement of the elevator 20 in the restoration operation is executed without agreement with the customer. Therefore, after 6 am on weekdays, the remote restoration action distinguishing "a" cannot be performed, but the remote restoration action distinguishing "B" can be performed. Further, after 6 am on saturday or sunday, the customer agrees to perform the recovery action with the distinction "a" of the movement of the elevator 20 in the recovery action, and the customer agrees to perform the remote recovery action without the distinction "B" of the movement of the elevator 20 in the recovery action. Therefore, the recovery action of discrimination "a" can be performed by the customer and discrimination "B" can be performed remotely after 6 am on saturday, sunday.
The recovery operation condition database 390 shown in fig. 9 includes an operation condition schedule 397 indicating the time slots of the specific days of the elevator 20 with the management number "789012" described above with reference to fig. 8, and distinguishes the remote recovery operation agreed upon for execution by the customer. As shown in the action condition schedule 397 of fig. 9, on a specific day, regardless of the period, the remote restoration actions of the distinction "a" and the distinction "B" are not executed in agreement with the customers, and the arbitrarily distinguished remote restoration actions cannot be executed.
The recovery operation conditions described above are determined by the operation status of the elevator 20 of the customer, the maintenance management status such as the presence or absence of a manager standing still, and the like. Therefore, the remote recovery system 100 of the present embodiment includes the customer terminal 400 that communicates with the remote recovery apparatus 300 via the communication network 37. The customer can access the recovery operation condition database 390 of the remote recovery device 300 through the customer terminal 400, and update or change the recovery operation conditions as needed according to the operation status and maintenance management status of the elevator 20.
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, 10, and 11. 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 first will be described. Next, a remote recovery operation in the case where the failure code "0002" relating to the control circuit embedded in the control panel 210 is transmitted will be described. The remote recovery system 100 can also cope with a case where a fault code relating to a part other than the above is transmitted.
As shown in fig. 2 and step S101 of fig. 10, 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 the doors 13 and 26 of the elevator 20, for example, a failure such as a door failure, the control panel 210 outputs the date and time of the failure occurrence, a failure code "0001" indicating that the failure is a failure in the doors, failure location information, and operation data immediately before the failure of the elevator 20 immediately before the failure occurs to the 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", the trouble location information, and the operation data immediately before the trouble occurs are input from the control panel 210, the communication device 250 transmits a trouble signal including the trouble code "0001", the trouble location information, the operation data immediately before the trouble occurs, 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 10. As shown in fig. 2 and step S103 of fig. 10, the communication device 320 of the remote monitoring center 310 receives the failure signal transmitted from the communication device 250 via the communication network 30. Upon receiving the failure signal, the communication device 320 outputs the failure code "0001", the failure location information, the operation data immediately before the failure occurs, the management number of the elevator 20, and the failure occurrence date and time to the 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.
The information processing apparatus 360 proceeds to step S104 shown in fig. 10, and selects a restoration instruction and a restoration diagnosis instruction corresponding to the failure code "0001". As described above with reference to fig. 5, the recovery diagnosis database 380 is a database that connects the recovery diagnosis instruction set, the recovery rate, and the recovery action section with the failure factor type data 379. Hereinafter, the data structure of the recovery diagnosis database 380 in the case where the failure code is "0001" indicating a failure in the doors 13 and 26 will be briefly described again. When the door sill is a cause of the dust jam (cause of failure 1), the recovery diagnosis data is a data structure in which a recovery diagnosis command set a, which is a set of two commands of "gate reset + gate high torque opening/closing" as a recovery command and "gate opening/closing diagnosis" as a recovery diagnosis command, a recovery rate a% of recovery operation according to the recovery command, and the number data of the cause of failure 1 are connected to the recovery operation classification "a". Similarly, when the switch contact failure of the door opening/closing device is a factor (failure factor 2), the recovery diagnosis data is a data structure in which a recovery diagnosis command set B, which is a set of two commands of "gate reset + gate opening/closing retry" as a recovery command and "gate opening/closing diagnosis" as a recovery diagnosis command, a recovery rate B% at which a recovery operation is performed in accordance with the recovery command, and a recovery operation classification "a" are connected to the number data of the failure factor 2. Similarly, in the case of the failure factor 3, the recovery diagnosis data is a data structure in which the recovery diagnosis command set C, the recovery rate C%, and the recovery operation classification "a" are connected to the number data of the failure factor 3. As described above, the recovery rate a% is a numerical value larger than the recovery rates B% and C%, and the recovery rate of the recovery diagnostic instruction set B is higher than the recovery rates of the recovery diagnostic instruction sets a and C.
The information processing apparatus 360 may select, as the restoration instruction, an instruction corresponding to the failure principal cause having the largest number of pieces out of the plurality of failure principal causes corresponding to the failure code "0001". Further, the information processing apparatus 360 may select, as the restoration instruction, an instruction having the highest restoration rate among the plurality of instructions corresponding to the failure code "0001". Also, the information processing apparatus 360 selects a recovery diagnosis instruction set in which the selected recovery instruction is grouped with a recovery diagnosis instruction corresponding to the selected recovery instruction.
First, a case will be described in which the information processing apparatus 360 selects, as a restoration instruction, an instruction corresponding to the failure factor having the largest number of failure factors among the plurality of failure factors corresponding to the failure code "0001". The information processing apparatus 360 refers to the restoration diagnosis database 380 as a restoration command, and confirms the cause of the failure with the largest number of times when the failure code is "0001". Then, the information processing device 360 selects a recovery diagnosis command set a composed of two commands, i.e., "gate reset + gate high torque opening/closing" as a recovery command for executing a recovery operation corresponding to a dust jam (failure cause 1) of the gate sill, which is a failure cause having the largest number of failures, and "gate opening/closing diagnosis" as a recovery diagnosis command for executing a recovery diagnosis operation corresponding to a result of the recovery operation.
Next, a case will be described in which the information processing apparatus 360 selects, as a recovery instruction, an instruction having the highest recovery rate among a plurality of instructions corresponding to the fault code "0001". The information processing apparatus 360 refers to the restoration diagnosis database 380, and confirms the restoration rate corresponding to the failure code "0001" that has the highest restoration rate as the restoration instruction. Then, the information processing apparatus 360 selects a recovery diagnosis command set B composed of two commands, i.e., "gate reset + gate open/close retry", which is a recovery command for executing a recovery operation corresponding to the cause of the switching contact failure (failure cause 2) having the highest recovery rate B%, and "gate open/close diagnosis", which is a recovery diagnosis command for executing a recovery diagnosis operation corresponding to the result of the recovery operation.
In the case of selecting the recovery diagnosis instruction set, whether the recovery rate is based on the failure leading cause having the largest number of pieces corresponding to the failure code "0001" or based on the recovery diagnosis instruction set corresponding to the failure code "0001" may be selected as follows. For example, the ratio of the maximum number of cells to the second number of cells (the number ratio) and the ratio of the maximum recovery rate to the second maximum recovery rate (the recovery rate ratio) may be selected to be larger, that is, to be larger than the second maximum value. Further, for example, in the case of failure in the last remote recovery, a selection method different from the last one may be adopted. The selection of the restoration diagnosis command set may be determined, for example, according to the model, specification, and the like of the elevator 20.
In the following description, a case will be described in which the information processing device 360 selects the restoration diagnosis instruction set a based on the failure factor 1 having the largest number of pieces corresponding to the failure code "0001".
After selecting the restoration diagnostic instruction set a in step S104 in fig. 10, the information processing apparatus 360 proceeds to step S105 in fig. 10, and determines whether or not the remote restoration operation can be performed using the selected restoration diagnostic instruction set.
The information processing device 360 refers to the recovery operation condition database 390 shown in fig. 6 to 9, and searches the operation condition schedules 391, 393, 395, and 397 corresponding to the elevator 20 in which the failure has occurred. When the input failure occurrence day matches a day specified in the normal day schedule, it is determined whether or not the recovery diagnosis command set selected in step S104 in fig. 10 can be executed by referring to the normal operation condition schedules 391 and 395 shown in fig. 6 and 8.
As an example, the elevator 20 in which the failure occurred is an elevator 20 to which the recovery operation condition database 390 defined in fig. 6 is applied, and is scheduled to be operated on sunday at 9 am: 00 a case where the remote resume action is performed will be described. In this case, according to the operation condition schedule 391 defined in fig. 6, the recovery diagnosis instruction set corresponding to the recovery action classification "a" cannot be remotely executed, and only the recovery diagnosis instruction set corresponding to the recovery action classification "B" can be remotely executed. Therefore, the information processing apparatus 360 determines that the recovery diagnosis instruction set a classified as "a" cannot be remotely executed, and proceeds to step S125 in fig. 10.
In step S125 of fig. 10, the information processing apparatus 360 determines whether or not it is possible to perform the remote recovery action on sunday 9 am of the week: 00 the recovery diagnosis instruction set a is executed by a customer operation. As shown in operation condition schedule 391 of fig. 6, since there is no Δ flag indicating that the customer has reached an agreement regarding the execution of the recovery operation within the date and time, information processing apparatus 360 determines no at step S125 of fig. 10 and proceeds to step S130 of fig. 11. Then, 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 S131 in fig. 2 and 11. Then, as shown in step S132 of fig. 2 and 11, the monitoring person 334 instructs the service center 340 near the building 10 to dispatch a technician 350 to the building 10 via the telephone 333.
On the other hand, in the morning scheduled on sunday 5: 00 when the remote resume operation is executed, the set of resume diagnostic instructions corresponding to the resume operation classification "a" and the set of resume diagnostic instructions corresponding to the resume operation classification "B" can be remotely executed according to the operation condition schedule 391 defined in fig. 6. Therefore, the information processing apparatus 360 determines that the recovery diagnosis instruction set a classified as "a" is capable of remotely executing the recovery operation.
In addition, when the remote recovery action is scheduled to be executed on the specific day shown in fig. 7, the recovery diagnosis instruction set corresponding to the recovery action classification "a" and the recovery diagnosis instruction set corresponding to the recovery action classification "B" can be remotely executed according to the action condition schedule 391 defined in fig. 7. Therefore, the information processing apparatus 360 determines that the recovery diagnosis instruction set a classified as "a" is capable of remotely executing the recovery operation.
Next, as shown in fig. 2 and 3, the information processing device 360 acquires the model, the date of manufacture, and the number of manufacture 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 by the restoration command and the restoration diagnosis command from the remote restoration device 300, based on the acquired specification data. If the elevator 20 is a model in which the remote return operation cannot be performed, the process proceeds to step S125 in fig. 10.
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) The elevator 20 has recently transmitted a fault signal of the same fault code.
If the above-described conditions (a) to (f) are satisfied, the information processing apparatus 360 determines that the remote restoration is performed by a customer operation or a technician 350 is dispatched to the building 10, rather than the remote restoration performed by the remote restoration system 100, and determines no in step S105 in fig. 10. Then, the information processing apparatus 360 proceeds to step S125 of fig. 10.
On the other hand, in step S105 shown in fig. 10, as shown in fig. 2, the information processing apparatus 360 checks the following (g) to (m) 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.
(i) Elevator 20 has no maintenance schedule at the latest or the same day and is not predicted to have the possibility of a misadjustment.
(j) There is no diagnosis result of abnormality of the elevator 20 in the remote spot 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 for the same fault code.
When all of the above requirements (g) to (m) are satisfied and remote restoration of the restoration diagnosis instruction set a is possible with reference to the restoration operation condition database 390, the information processing apparatus 360 determines yes in step S105 shown in fig. 10, proceeds to step S106 in fig. 10, and determines the restoration diagnosis instruction set used for remote restoration as the restoration diagnosis instruction set a.
Then, the information processing apparatus 360 proceeds to step S107, and notifies the remote monitoring center 310 of the start of remote restoration. 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.
The information processing apparatus 360 proceeds to step S108 of fig. 10, and transmits the determined restoration diagnostic instruction set a from the communication apparatus 320. As shown in fig. 2 and step S109 of fig. 10, 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.
First, as shown in step S110 of fig. 10, the control panel 210 checks whether the elevator 20 is stopped, and checks whether there is a passenger in the car 22 based on outputs of a weight sensor of the car 22, a camera in the car 22, a human sensor in the car 22, and the like. After confirming that the elevator 20 is stopped and that there is no passenger in the car 22, the control panel 210 performs "now remote recovery from the start" 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 finished, the control panel 210 proceeds to step S111 in fig. 10, and performs a resume operation in response to the resume command. Since the currently received restoration command is a restoration command for executing a restoration operation corresponding to the garbage jam of the door sill (cause 1 of failure), that is, "gate reset + high-door-torque opening/closing", 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 makes the torque ratio of the drive motors of the doors 13 and 26 higher by 20% to 30% than usual, and opens and closes the doors 13 and 26 with a force larger than usual. 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. In order to confirm whether or not the opening and closing of the doors 13 and 26 are resumed by the movement of the dust jammed in the sills of the doors 13 and 26 by the above-described operation, the control panel 210 executes "door opening and closing diagnosis" as a resume diagnosis command, as shown in step S112 of fig. 10. 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 operations can be performed with a predetermined opening and closing time, and whether the current of the drive motors 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 S113 of fig. 10, when the control panel 210 determines that the doors 13 and 26 are restored to the normal state by the restoration diagnostic operation, the process proceeds to step S114 of fig. 10. In step S114, 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 S115 of fig. 11, the communication device 320 receives the issued determination result signal, and the determination result is input to the information processing device 360. Further, as shown in step S116 of fig. 11, 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 broadcast operation, as shown in step S117 of fig. 11. Further, as shown in step S118 and step S119 in fig. 11, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380.
On the other hand, if the result of the recovery diagnosis operation is determined as no in step S113 in fig. 10, the control panel 210 proceeds to step S120 in fig. 10. In step S120, 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 S121 of fig. 11, the communication device 320 receives the issued determination result signal, and the determination result is input to the information processing device 360. Further, as shown in step S121 of fig. 11, 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 S123 of fig. 11. Further, as shown in step S124 of fig. 2 and 11, 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, as shown in step S118 and step S119 in fig. 11, the information processing apparatus 360 updates the maintenance database 370 and the recovery diagnosis database 380.
When a determination signal indicating that the elevator 20 has recovered as shown in step S114 of fig. 10 is input, the information processing device 360 updates the maintenance database 370 as follows.
When a determination signal indicating that the elevator 20 has recovered as shown in step S114 of fig. 10 is input, the information processing device 360 stores "remote recovery" in the item of the recovery method of the failure history data 377 and stores "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 the items of the failure history data 377 are updated by storing the recovery method and the recovery determination result of this time.
In the present remote recovery, the information processing apparatus 360 refers to the recovery diagnosis database 380, and selects a recovery diagnosis command set a composed of two commands, i.e., "gate reset + gate closing retry", which is a recovery command for performing a recovery operation corresponding to the "garbage jam of the gate sill (failure cause 1), which is the failure cause for the largest number of failures in the case of the failure code" 0001 ", and" gate open/close diagnosis ", which is a recovery diagnosis command for performing a recovery diagnosis operation corresponding to the result of the recovery operation, so that the recovery operation and the recovery diagnosis operation are performed. Therefore, when the elevator 20 is successfully restored, the restoration rate is improved by adding 1 to the failure code "0001" in the restoration diagnosis database 380 and the number of the failure cause 1 (the garbage jam of the doorsill), according to the success of the restoration. Further, the information processing device 360 adds 1 to the number of failure cause 1 of the failure code "0001" of the failure cause type data 379.
On the other hand, when a determination signal indicating that the recovery of the elevator 20 has failed as shown in step S120 of fig. 10 is input, the information processing device 360 updates the maintenance database 370 and the recovery diagnosis database 380 as follows. When a determination signal indicating that the elevator 20 has failed to recover as shown in step S120 of fig. 10 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. Further, the number of the failure code "0001" and the number of the failure factor 1 (garbage jam of the threshold) in the restoration diagnosis database 380 are kept constant, and the restoration rate is decreased according to the restoration failure. In addition, when recovery fails, the number of failure cause 1 of the failure code "0001" in the failure cause type data 379 is not changed.
In the above description, the case where the information processing apparatus 360 selects the restoration diagnosis instruction set a based on the failure factor having the largest number of pieces corresponding to the failure code "0001" has been described. When the information processing device 360 selects the recovery diagnosis command set B based on the recovery rate of the recovery diagnosis command set corresponding to the failure code "0001", the difference is that a recovery operation of "door opening/closing retry" in which the opening/closing operations of the doors 13 and 26 are performed again at normal torque is performed instead of the recovery operation of "door high-torque opening/closing". The other actions are the same as in the case where the recovery diagnosis instruction set a is selected.
If the remote restoration of the elevator 20 is successful, the number of the door sill garbage jam (failure cause 1) which is the failure cause having the largest number of the failure codes "0001" has been increased. Therefore, in the case where the remote recovery system 100 selects the recovery diagnosis instruction set based on the failure factor having the largest number of times corresponding to the failure code "0001", the information processing device 360 selects the recovery diagnosis instruction set a again when the failure code "0001" is input at the next remote recovery. Further, when the recovery rate of the recovery diagnosis instruction set a becomes higher than that of the recovery diagnosis instruction set B, the information processing apparatus 360 also selects the recovery diagnosis instruction set a in a case where an instruction having the highest recovery rate among the plurality of instructions corresponding to the fault code "0001" is selected as the recovery instruction.
On the other hand, if the remote recovery of the elevator 20 fails, the recovery rate of the recovery diagnosis command set a decreases although the number of failure causes 1 in the failure code "0001" of the failure cause type data 379 is not changed. Thus, the recovery rate for recovering the diagnostic instruction set B becomes relatively high. That is, the recovery rate ratio of the recovery diagnostic instruction set B with respect to the recovery diagnostic instruction set a becomes high. When the recovery rate ratio becomes larger than the number-of-items ratio calculated as the ratio of the number of failure causes 1 to the number of failure causes 2, the information processing device 360 selects, as a recovery command, a command having the highest recovery rate among the plurality of commands corresponding to the failure code "0001". Therefore, when the failure code "0001" is input at the next remote recovery, the information processing apparatus 360 selects the recovery diagnosis instruction set B having the highest recovery rate. Further, in a case where the information processing apparatus 360 does not select the recovery diagnosis instruction set a in which recovery failed in the last remote recovery, the recovery diagnosis instruction set B connected to the failure principal cause 2 whose number of pieces corresponds to the failure code "0001" is several times as large as the failure principal cause 1 is selected.
When the information processing device 360 selects the recovery diagnosis command set B having the highest recovery rate among the plurality of commands corresponding to the trouble code "0001" and succeeds in the recovery of the elevator 20, the recovery rate of the recovery diagnosis command set B becomes high. Therefore, the information processing apparatus 360 selects the restoration diagnosis instruction set B in the next remote restoration in the same manner as in the previous remote restoration. On the other hand, if the recovery of the elevator 20 fails due to the recovery diagnosis command set B, the recovery rate of the recovery diagnosis command set B becomes low. Also, if the recovery rate of the recovery diagnosis instruction set B becomes lower than that of the recovery diagnosis instruction set a, the information processing apparatus 360 selects the recovery diagnosis instruction set a. In addition, in the case where the information processing apparatus 360 does not select the recovery diagnosis instruction set B whose recovery failed in the last remote recovery, the recovery diagnosis instruction set a having the recovery rate corresponding to the failure code "0001" next to the recovery diagnosis instruction set B is selected.
In this way, when the remote recovery is successful, the remote recovery system 100 increases the number of pieces of the failure factor and the recovery rate of the selected recovery diagnosis instruction set. Further, when the remote restoration fails, the remote restoration system 100 maintains the number of pieces of the failure factor, and decreases the restoration rate of the selected restoration diagnostic instruction set. Therefore, if the remote restoration is successful, the possibility that the restoration diagnostic instruction set selected in the remote restoration is selected at the next remote restoration becomes high. Further, if the remote recovery fails, the recovery diagnostic instruction set selected in the remote recovery becomes less likely to be selected the next time the remote recovery. Therefore, as the number of remote restoration increases, the information processing device 360 can select a restoration diagnosis command set having a high possibility of restoration corresponding to the trouble code from the restoration diagnosis database 380, and can improve the reliability of the restoration of the elevator 20.
Further, the information processing device 360 selects the restoration diagnosis instruction set a in step S104 in fig. 10, determines no in step S105 in fig. 10 when the scheduled date and time of execution of the remote restoration operation is daytime on weekdays, proceeds to step S125 in fig. 10, and determines yes in step S125 in fig. 10.
In this case, as shown in step S126 of fig. 10, the information processing device 360 transmits the restoration diagnosis instruction set a to the control panel 210 via the communication devices 320 and 250. Then, as shown in step S127 of fig. 10, the information processing device 360 communicates with the customer, transmits the restoration diagnosis instruction set a to the control panel 210, and switches the destination floor button 28, which is the input device of the elevator 20, to the live operation mode. Then, as shown in step S128 of fig. 10, the information processing device 360 outputs a command to switch the destination floor button 28, which is an input device of the elevator 20, to the on-site operation mode. The control panel 210 stores the restoration command included in the restoration diagnosis command set a and the contents of the restoration diagnosis command in the memory without executing them, and changes the destination floor button 28 to the on-site execution mode. In this way, by pressing the destination floor button 28 in a specific manner, execution of the restoration command and the restoration diagnosis command can be started.
The information processing device 360 stands by in step S129 of fig. 10 until a service manager or the like at the site presses the destination floor button 28 in a specific manner to execute a restoration command or a restoration diagnosis command. When the recovery command or the recovery diagnosis command is executed, the recovery operation is terminated.
If the destination floor button 28 is not pressed in a specific manner within the predetermined time and the return instruction or the return diagnosis instruction is executed, the information processing device 360 determines no in step S129 of fig. 10 and proceeds to step S130 of fig. 11. Then, 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 S131 in fig. 2 and 11. Then, as shown in step S132 of fig. 2 and 11, the monitoring person 334 instructs the service center 340 near the building 10 to dispatch a technician 350 to the building 10 via the telephone 333.
Next, a remote recovery operation in the case where the failure code "0002" relating to the control circuit embedded in the control panel 210 is transmitted will be described. The same operation as the remote restoration operation in the case where the failure code "0001" is transmitted as described above will not be described.
As described above with reference to reference numeral 382 of fig. 5, in the case of the trouble code "0002", the restoration diagnosis command set D, the restoration diagnosis command set E, and the restoration diagnosis command set F stored in the restoration diagnosis database 380 are all the divisions "B" that do not accompany the movement of the elevator 20 during the restoration operation. Therefore, as shown in fig. 6 and 7, in the case of the elevator 20 of the management number "123456", the remote restoration operation can be always performed. Therefore, in the elevator 20 of the management number "123456", when the recovery diagnosis command sets D to F are selected, the determination is yes in step S105 of fig. 10, and the remote recovery operation is executed below step S106 of fig. 10.
On the other hand, as shown in fig. 9, in the case of the elevator 20 of the management number "789012", any remote restoration action cannot be performed on a specific day. Therefore, in the elevator 20 of the management number "789012", the remote restoration cannot be performed on a specific day. In addition, the customer cannot perform the recovery action on a particular day. Therefore, the information processing device 360 determines no in both steps S105 and S125 in fig. 10, and proceeds to step S130 in fig. 11 to stop the operation of the elevator 20 and notify the remote monitoring center 310 of this fact.
The remote restoration action is the same as in the case of the failure code "0001" described earlier.
The remote recovery system 100 according to the embodiment described above can recover from a failure of the elevator 20 based on the elevator operation situation of the customer.
In addition, when various failures occur in the elevator 20, the remote recovery system 100 can perform the recovery of the elevator 20 by causing the elevator 20 to perform the recovery operation and the recovery diagnosis operation by a command from the remote recovery device 300 disposed at a place distant from the elevator 20. Therefore, even when the elevator 20 has a failure, the elevator 20 can be recovered in a short time without moving the technician 350 to the site, and the operation service of the elevator 20 can be improved.
Further, the remote restoration system 100 updates the failure history data 377, the failure factor type data 379, and the restoration diagnosis database 380 based on the restoration determination result, and can select a restoration diagnosis instruction set having a higher restoration possibility at the next remote restoration. Therefore, as the number of remote recoveries becomes larger, the information processing apparatus 360 becomes able to select a more appropriate recovery diagnosis instruction set corresponding to the trouble 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.
In the embodiment described above, the return operation distinction is described by assuming that the distinction accompanied by the motion of the elevator 20 in the return operation is the return operation distinction "a" when viewed from the outside and the distinction not accompanied by the motion of the elevator 20 is the return operation distinction "B" when viewed from the outside, but the return operation distinction is not limited to this distinction, and for example, the return operation may be distinguished by the presence or absence of the motion of a specific portion as in the case where the distinction accompanied by the opening and closing motion of the doors 13 and 26 in the return operation is viewed from the outside.
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.
