Description

Elevator remote monitoring device

The present invention relates to a device for remotely monitoring the status of an elevator.

BACKGROUND ART Conventionally, a remote management system for an elevator that intensively monitors the status of elevators in a plurality of buildings at a remote management center or the like is known. For example, the equipment diagnosis apparatus disclosed in patent document 1 accumulate|stores in the database the detection data which detected the process value of various equipment of a building, and failure data of each equipment. Then, when a certain device breaks down, the trend until it deviates from the normal value based on the historical data related to the device is analyzed to obtain a parameter for judging an abnormality. Moreover, a failure is predicted in advance by monitoring the frequency distribution created from the measurement data of almost the same type of equipment using the said parameter. For example, for a given device, a frequency distribution of a difference value between a set value and an actual value is created, the number of times that the difference value is included in a predetermined band of the frequency distribution is counted, and according to the number of times, A failure alarm is notified.

Moreover, the maintenance work support apparatus disclosed by patent document 2 diagnoses the presence or absence of malfunction of an elevator from the time difference between the ideal timing of each operation|movement of an elevator, and an actual timing.

By the way, when an elevator failure generate|occur|produces, when failure prediction is performed with respect to this and the elevator of similar specification, maintenance and inspection are performed according to the said failure prediction. For example, emergency maintenance inspection is performed separately from legal inspection. When the failure prediction is performed by statistical processing such as frequency distribution, depending on the accuracy of the elevator, which is the target of the emergency maintenance inspection based on the failure prediction, such an emergency maintenance inspection is not necessary for the elevator (sound) In some cases, even an elevator is included. Therefore, an object of the present invention is to provide a remote monitoring apparatus for an elevator capable of quickly determining whether an emergency maintenance inspection is necessary for an elevator similar to this when an elevator failure occurs.

[0001] The present invention relates to a remote monitoring apparatus of an elevator, which is capable of communicating with a plurality of elevator control apparatuses, which performs respective driving control of a plurality of elevators. The monitoring device includes a specification storage unit, a pseudo-elevator extraction unit, a diagnostic operation command unit, and a determination unit. The specification storage unit stores specifications of a plurality of elevators. When a failure signal is received from an arbitrary elevator control device, the similar elevator extraction unit extracts, based on the specification storage unit, a similar elevator in which at least one of the specification items and the elevator of the origin of the failure signal are common. The diagnostic operation command unit instructs the similar elevator to perform diagnostic operation. The determination unit determines whether maintenance or inspection is necessary based on the result of the diagnostic operation.

Moreover, in the said invention, when carrying out a diagnostic operation with respect to a similar elevator, you may provide the threshold value change part which changes the threshold value which distinguishes a normal value and an abnormal value to the normal value side.

Further, in the above invention, a diagnostic operation schedule setting unit may be provided for shortening the execution interval of the diagnostic operation for the similar elevator from a predetermined normal interval.

Moreover, in the said invention, you may provide the temporary abnormality setting part which sets the temporary abnormality identifier valid with respect to a similar elevator. In this case, the temporary abnormality setting unit may switch the temporary abnormality identifier from valid to invalid when it is determined that maintenance and inspection is unnecessary as a result of the diagnostic operation.

Moreover, in the said invention, you may provide the remote recovery apparatus which makes the elevator of the origin of a failure signal perform a failure recovery operation. In this case, the pseudo-elevator extracting unit may extract a pseudo-elevator from an elevator in which remote recovery by recovery operation is impossible or in which remote recovery has failed, among elevators from which the failure signal is transmitted.

ADVANTAGE OF THE INVENTION According to this invention, when an elevator malfunction generate|occur|produces, it becomes possible to determine quickly whether emergency maintenance and inspection is necessary for an elevator similar to this.

The elevator specification data 371 (specification storage unit) has a data structure for storing specification item data such as the management number, model, manufacturing date, manufacturing number, name of the installation building, and the purpose of the installation building of the elevator 20 . . Models are classified by installation situation such as, for example, model information classified by floor such as high-rise and low-rise use, model information classified by use such as residential use and multi-family housing, or whether the hoistway is an observation elevator exposed to sunlight. The model information is reflected. The use of the installation building is, for example, an office, a general residence, a restaurant, a school, and the like.

Moreover, the elevator specification data 371 has a data structure which stores the data of the installation environment and the number of times of rope bending. The installation environment is, for example, data indicating whether or not each device of the elevator 20 is in an environment prone to deterioration, such as a hot spring resort, a coastal area, a factory, or the like. In addition, the number of times of rope bending is data indicating the number of times that the wire 23 is bent by a sheave. In addition to this, hoistway height data may be included.

The inspection history data 372 has a data structure that stores the management number of the elevator 20, the date and time of the inspection performed locally by the technician 350, inspection items, and data of inspection results. Inspection is, for example, inspection of the opening and closing state of doors 13 and 26 of elevator 20 shown in Fig. 1, inspection of stop positions of each floor (floor floor 12 and floor of car 22) 27), inspection of the amount of deviation in height), inspection of the wire 23, inspection of running speed, and the like. In addition, in the inspection result, whether or not an abnormality was found as a result of the inspection, maintenance work such as cleaning is required even though no abnormality is found, or parts replacement is required are inputted to the inspection result. In Fig. 1, reference numeral 25 denotes a weight.

The maintenance work history data 373 has a database structure that stores the management number of the elevator 20, the maintenance work date and time of the elevator 20 performed by the technician 350 on site, the maintenance work items, and the maintenance work results. The maintenance work items include, for example, inspection of the operating state of the elevator 20 , cleaning of the door rails of the elevator 20 , oil supply to the drive device 24 shown in FIG. 1 , adjustment of the brakes of the elevator 20 , etc. am. The results of inspection, cleaning, oil supply, adjustment, etc. are input to the maintenance work result.

The remote inspection history data 374 has a data structure for storing the management number of the elevator 20, the remote inspection date and time, the remote inspection items, and the remote inspection result. The remote inspection of the elevator 20 is also called remote diagnosis, as will be described later, for example, according to a preset schedule such as once a month, or when selected as a similar elevator as described later, This is performed by the control panel 210 . 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, it is checked whether there are any abnormalities in driving performance (acceleration, presence or absence of abnormal sound), door opening and closing, brake, emergency battery, external communication device, and the like by various sensors mounted on the elevator 20 . The inspection result is stored in the remote inspection history data 374 from the information processing device 360 via the communication devices 250 and 320 and the communication network 30 . In addition, as for the remote inspection (remote diagnosis), an execution command is output by the diagnosis operation command part 402 of the information processing apparatus 360 so that it may mention later.

The tampering history data 375 has a data structure that stores the management number of the elevator 20, the tampering date and time, the tampering item, and the tampering result. The modulation of the elevator 20 refers to a case in which the result of inspection, inspection, maintenance work, or remote inspection by the technician 350 does not reach an abnormal value, but is changed from the normal value of the elevator 20 . In other words, an intermediate state provided between normality and abnormality is modulation. For example, if the test result of the running speed is within the allowable value, but the difference from the value of the inspection result of the previous inspection or the elevator 20 up to the present is large, among the modulation items, " running speed”.

The repair work history data 376 has a data structure that stores the management number of the elevator 20, the repair work date and time, the repair work item, the repair work result, and replacement parts. The repair work is a repair work by replacement of parts such as replacement of the wire 23, replacement of the hanger roller, replacement of the brake pad, replacement of the control board, and replacement of the relay. Therefore, the names of replacement parts such as “wire replacement”, “hanger roller replacement”, and “brake pad replacement” are entered in the repair work item, and “repair work completed” and “re-repair required” are entered in the column of the repair work result. ' is entered. Items such as “wire”, “hanger roller” and “brake pad” are input to the replacement part.

The failure history data 377 has a data structure storing the management number of the elevator 20, the failure occurrence date and time, the failure code, the recovery method, and the recovery determination result. The failure code is a code that combines numbers or numbers and English characters output from the control panel 210 when a failure occurs in the elevator 20 . The types of fault codes are, for example, about 1000 types. In the item of the restoration method, for example, when the technician 350 is dispatched to conduct inspection, inspection, and restoration, it is input as "departure of technician". In the recovery method item, for example, when recovery is performed by the remote recovery system 100, “remote recovery” is input. When the elevator 20 is restored and the operation is resumed, the item of the restoration determination result is input as "restore". In addition, when the elevator 20 fails in restoration, it is input as "failure" in the item of the restoration determination result.

The data 378 for each failure factor is, when a certain failure code is output from the control panel 210, the number of failure factors corresponding to the failure code according to the result of inspection and inspection by the technician 350 to the site, and, The total number of failure factors corresponding to the failure code in the case of recovery by the remote recovery system 100 is stored. For example, if the fault code is 0001 indicating a fault with the doors 13 and 26, as a result of local inspection by the technician 350, the cause of the fault code “0001” outputting is the accumulation of garbage on the door sill ( Failure factor 1), or defective contact of the switch of the door opening/closing device (failure factor 2), or other failure factor 3 Therefore, in the data for each failure factor, when the failure code "0001" is output, 100 cases are caused by the accumulation of garbage on the door sill (failure factor 1), and the contact failure of the switch of the door opening and closing device is a factor (failure factor 2) It has the same data structure as 50 cases for , and 10 cases for other failure factors 3, and the data is arranged in the order of the largest number of cases. In the case of recovery by the remote recovery system 100, when the recovery of the elevator 20 is successful according to the recovery command, the number of fault factors corresponding to the fault code that became the basis of the recovery command is the total number of fault factors. is added to

In the driving history data 379, each data of the operation rate, the number of times of opening and closing of the platform door, the number of times of opening and closing of the car door, the number of stops, the mileage, the total running time, and the number of starts is stored. The utilization rate is obtained from MTBF/(MTBF+MTTR) using the mean time between failures (MTBF), which indicates the time between failure and the next failure, and the mean repair interval (MTTR), which is the average of the time taken to repair. As for the number of times of opening and closing of the platform door, the number of times of opening and closing the platform door 13 is recorded for each floor. As for the number of times of opening and closing of the car door, the number of times of opening and closing of the door 26 of the car 22 is recorded. As for the number of stops, the number of stops of the car 22 is recorded for each floor. As for the travel distance, the total travel distance of the car 22 is recorded. As for the total running time, the total running time of the car 22 is recorded. The number of starts counts from engagement (braking) of a brake (not shown) to the next engagement once, and the total count is recorded.

As shown in FIG. 4 , the recovery diagnosis database 380 includes a recovery diagnostic command set that is a set of recovery commands and recovery diagnostic commands in the order of the number of fault factors in the data 378 for each fault factor 378, and the recovery commands. The recovery rate (%), which is the rate at which the failure of the elevator 20 is recovered by the execution of , is stored. The recovery diagnosis database 380 is a database in which the recovery diagnosis command set and the recovery rate are linked to the data 378 for each failure factor described above.

Hereinafter, the data structure of the recovery diagnosis database 380 in the case where the failure code is "0001" indicating a failure related to the doors 13 and 26 will be described. When the accumulation of garbage on the door sill is a factor (failure factor 1), the recovery diagnostic data is "door circuit reset + door high torque opening/closing" as a recovery command to the number of fault factor 1 data, and "door" as a recovery diagnostic command It has a data structure in which a recovery diagnosis command set A, which is a set of two commands of "open/close diagnosis", and a recovery rate x% by a recovery operation according to the recovery command are linked. Similarly, when the contact failure of the switch of the door opening/closing device is a factor (failure factor 2), the recovery diagnostic data is “door circuit reset + door opening/closing retry” as a recovery command to the number of fault factor 2 data, and “door circuit reset + door opening/closing retry” as a recovery diagnostic command. It has a data structure in which a recovery diagnostic command set B, which is a set of two commands of “door opening/closing diagnosis”, and a recovery rate y% of the recovery operation according to the recovery command are linked. Similarly, in the case of the failure factor 3, the recovery diagnostic data has a data structure in which the recovery diagnostic command set C and the recovery rate z% are linked to the failure factor 3 case count data. In this way, the recovery diagnosis database 380 associates a failure code, a failure factor corresponding to the failure code, the number of the failure factors, a recovery diagnosis command set, which is a set of recovery instructions and recovery diagnosis, and a recovery rate to the database. will be stored in In this embodiment, the recovery rate y% is a numerical value larger than the recovery rates x% and z%, and the recovery diagnostic instruction set B has a higher recovery rate than the recovery diagnostic instruction set A and the recovery diagnostic instruction set C.

Hereinafter, an operation of the remote recovery system 100 when a failure signal is transmitted from the elevator 20 will be described with reference to FIGS. 2, 5, and 6 . In the following description, first, the remote recovery operation when the failure code signal "0001" regarding the doors 13 and 26 is transmitted will be described. Next, the remote recovery operation in the case where the failure code "0002" related to the control circuit provided in the control panel 210 is transmitted will be described. Next, the remote recovery operation in the case where the failure code "0003" related to the brake in the drive device 24 is transmitted will be described. In addition, the remote recovery system 100 can respond even when a failure code related to a part other than the above is transmitted.

As shown in step S101 of FIGS. 2 and 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 with respect to the doors 13 and 26 of the elevator 20, for example, a failure such as door opening and closing failure occurs, the control panel 210 displays a failure code indicating the date and time of the failure and the failure related to the door. "0001" is output to the communication device 250 . If no failure occurs in the elevator 20 , the control panel 210 returns to the beginning of step S101 and continues monitoring the elevator 20 .

When the failure code "0001" is inputted from the control panel 210 in the communication device 250, as shown in step S102 of FIGS. 2 and 5, the failure code "0001" and the management number of the elevator 20 and the failure occurrence date and time It transmits a fault signal including a to the communication network 30 . 2 and 5 , the communication device 320 of the remote monitoring center 310 receives a failure signal transmitted by the communication device 250 via the communication network 30 . When the communication device 320 receives the failure signal, the failure code “0001” included in the failure signal, the management number of the elevator 20, and the failure occurrence date and time are output to the information processing apparatus 360 . The information processing device 360 stores the input 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 or not the elevator 20 in which the failure has occurred is remotely recoverable. As shown in FIGS. 2 and 3 , the information processing device 360 acquires the model, manufacturing date, and serial number of the elevator 20 from the elevator specification data 371 using the management number of the elevator 20 . Based on the acquired specification data, the information processing device 360 confirms whether the elevator 20 is of a specification capable of a recovery operation and a recovery diagnosis operation according to a recovery command and a recovery diagnosis command from the remote recovery device 300 . do. When the elevator 20 is of a model in which the remote recovery operation is impossible, the information processing device 360 sends a signal for notifying the remote monitoring center 310 of remote recovery impossibility, as shown in step S124 of FIGS. 2 and 5 . to output

And, in the case of any one or more of (a) to (f) above, the information processing device 360 dispatches the technician 350 to the building 10 rather than the recovery by the remote recovery system 100 . It is judged that one is better, and NO is judged in step S104 of Fig. 5 . And as shown in step S124 of FIG.2 and FIG.5, the information processing apparatus 360 outputs the notification of remote recovery impossibility to the remote monitoring center 310. As shown in FIG.

In addition, the information processing device 360 uses the management number of the elevator 20 to determine whether the building 10 is a building in which there are many mistransmissions of failure signals from the elevator specification data 371 and the failure history data 377 . Check it. In such a case, the information processing device 360 determines that it is better to dispatch the technician 350 to the building 10 rather than the recovery by the remote recovery system 100 because the possibility of erroneous transmission of the failure signal is high. , it is determined as NO in step S104 of FIG. 5 . Then, the information processing device 360 outputs a notification of remote recovery impossibility to the remote monitoring center 310 as shown in step S124 of FIGS. 2 and 5 .

The notification of remote recovery impossibility output from the information processing device 360 to the remote monitoring center 310 is displayed on the display 331 of the remote monitoring center 310 as shown in FIG. 2 . When the monitor 334 confirms this display, as shown in step S125 of FIGS. 2 and 6 , the supervisor 334 makes an instruction to stop the operation of the elevator 20 and an announcement operation. Then, the supervisor 334 dispatches the technician 350 to the building 10 by the telephone 333 to the service center 340 adjacent to the building 10 as shown in step S126 of FIGS. 2 and 6 . instruct to do

When it is determined in step S104 of Fig. 5 that the elevator 20 is not remotely recoverable, the information processing device 360 in step S103 includes the input failure code "0001", the management number of the elevator 20, and failure. The occurrence date and time are stored in the failure history data 377 of the maintenance database 370 . Then, the information processing device 360 ends the remote recovery operation without updating other data in the maintenance database 370 and updating the recovery diagnosis database 380 .

On the other hand, in step S104 shown in FIG. 5, as shown in FIG. 2, the information processing apparatus 360 inspection history data 372, maintenance work history data 373, remote inspection history data 374, and falsification. With reference to the history data 375, the repair work history data 376, and the failure history data 377, it confirms about the following (g) - (n).

Notifies the start of recovery. This signal is displayed on the display 331 of the remote monitoring center 310 . Thereby, the supervisor 334 of the remote monitoring center 310 is notified that the remote recovery of the elevator 20 is started.

When the information processing device 360 notifies the remote monitoring center 310 of the remote recovery start in step S105, the information processing device 360 proceeds to step S106 shown in FIG. choose As previously described with reference to FIG. 4 , the recovery diagnosis database 380 is a database in which a recovery diagnosis command set and a recovery rate are linked to the data 378 for each failure factor. Hereinafter, the data structure of the recovery diagnosis database 380 in the case where the failure code is "0001" indicating a failure related to the doors 13 and 26 will be briefly described again. When the accumulation of garbage on the door sill is a factor (failure factor 1), the recovery diagnostic data includes “door circuit reset + door high torque opening/closing” as a recovery command to the failure factor 1 case count data, and “door opening/closing diagnosis” as a recovery diagnostic command.

Similarly, in the case of the failure factor 3, the recovery diagnostic data has a data structure in which the recovery diagnostic command set C and the recovery rate z% are linked to the number data of the failure factor 3. As described above, the recovery rate y% is a numerical value greater than the recovery rates x% and z%, and the recovery diagnostic instruction set B has a higher recovery rate than the recovery diagnostic instruction set A and the recovery diagnostic instruction set C.

The information processing device 360 may select, as the recovery command, a command corresponding to the fault factor having the largest number of fault factors among a plurality of fault factors corresponding to the fault code "0001". Further, the information processing device 360 may select a command having the highest recovery rate among a plurality of commands corresponding to the failure code "0001" as the recovery command. Then, the information processing device 360 selects a recovery diagnostic command set in which the recovery diagnostic command corresponding to the selected recovery command is set with the selected recovery command.

First, a description will be given of a case in which the information processing device 360 selects, as a recovery command, a command corresponding to the fault factor having the largest number of fault factors from among a plurality of fault factors corresponding to the fault code "0001". The information processing device 360 refers to the recovery diagnosis database 380 and confirms the failure factor with the largest number of cases in the case of the failure code "0001" as the recovery instruction. In addition, the information processing device 360 performs a recovery command "door circuit reset + door high torque opening/closing", which is a recovery command that executes a recovery operation corresponding to the accumulation of garbage on the door sill (failure factor 1), which is a failure factor with the highest number of cases; A recovery diagnostic command set A consisting of two recovery diagnostic commands "door open/close diagnostics"

Next, a case will be described in which the information processing device 360 selects, as the recovery command, the command with the highest recovery rate among the plurality of commands corresponding to the failure code "0001". The information processing device 360 refers to the recovery diagnosis database 380 and confirms the recovery rate with the highest recovery rate corresponding to the failure code "0001" as the recovery command. Then, the information processing device 360 transmits "door circuit reset + door opening/closing retry" which is a recovery command for executing a recovery operation corresponding to the contact failure factor (failure factor 2) of the switch having the highest recovery rate y%, and this A recovery diagnostic command set B consisting of two recovery diagnostic commands "door open/close diagnostics"

When selecting the recovery diagnostic command set, the selection of whether based on the failure factor with the largest number of cases corresponding to the fault code “0001” or the recovery rate of the recovery diagnostic command set corresponding to the fault code “0001” is as follows. may be done For example, among the ratio of the maximum number of cases to the next number (number of cases) and the ratio of the maximum recovery rate and the next recovery rate (recovery rate ratio), the one with the larger ratio, that is, the one with the largest protruding value for the next numerical value, is selected. You may choose Also, for example, when the previous remote recovery fails, a selection method different from that of the previous time may be taken. In addition, the selection of the recovery diagnosis command set may be determined by, for example, the model and specifications of the elevator 20 .

In the following description, the case where the information processing device 360 selects the recovery diagnosis instruction set A based on the failure factor 1 with the largest number of cases corresponding to the failure code "0001" will be described.

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

The control panel 210 is first, as shown in step S109 of FIG. 5 , that the elevator 20 is stopped, the weight sensor of the car 22 , the camera in the car 22 , and the car 22 . From the output of the person sensor or the like inside, it is confirmed that there are no passengers in the car 22 . Then, when it is confirmed that the elevator 20 is stopped and that there are no passengers in the car 22, the control panel 210 sends a message from the speaker of the call device installed in the car 22 to "Start remote recovery from now on." do. Elevator door opens and closes."

When the announcement is finished, the control panel 210 proceeds to step S110 in FIG. 5 and executes a restoration operation according to the restoration instruction. Since the currently received recovery command is "door circuit reset + door high-torque opening/closing", which is a recovery command that executes a recovery operation corresponding to the accumulation of garbage on the door sill (failure factor 1), the control panel 210 first , the door circuit of the control panel 210 is reset. This operation resets the state in which the door circuit detects that the door 13 or the door 26 cannot be opened and closed, an open (or closed) state, or a half-open (or half-closed) state, and the door 13 Alternatively, it is an operation that enables the opening and closing operation of the door 26 . Next, the control panel 210 increases the torque of the driving motors of the door 13 and the door 26 by 20 to 30% higher than usual, and opens and closes the door 13 and the door 26 with a greater force than usual. This operation is an operation for moving the garbage accumulated on the door sill from the sill to restore the opening/closing operation of the doors 13 and 26 to the normal state. In order to check whether the garbage accumulated on the threshold of the doors 13 and 26 is moved by the above operation and the opening and closing of the doors 13 and 26 have been restored, the control panel 210 is As described above, "door opening/closing diagnosis" which is a recovery diagnosis command is executed. The control panel 210 opens and closes the door 13 and the door 26 with a normal torque to determine whether the opening/closing operation is performed at a predetermined opening/closing time, and the current of the driving motor of the door 13 and the door 26 is normally Check that it is not larger than that. Next, the control panel 210 opens and closes the door 13 and the door 26 by setting the torque of the driving motor to about 20% lower than usual, and checks whether there is an abnormality in the opening and closing time.

And as shown in step S112 of FIG. 5, when the control panel 210 determines that the doors 13 and 26 have been restored to the normal state by the restoration diagnosis operation, it progresses to step S113 of FIG. In step S113, the control panel 210 outputs a determination result signal indicating that the elevator 20 has been restored. This signal is transmitted from the communication device 250 to the communication network 30 . The transmitted judgment result signal is received by the communication device 320 as shown in step S114 of FIG. 6 , and the judgment result is input to the information processing device 360 . Further, as shown in step S115 of FIG. 6 , the determination result is notified from the information processing device 360 to the remote monitoring center 310 , and the result is displayed on the display 331 of the remote monitoring center 310 . . When the monitor 334 of the remote monitoring center 310 confirms this display, as shown in step S116 of FIG. 6, the operation restart of the elevator 20 and an announcement operation are performed. Further, the information processing device 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in steps S117 and S118 of FIG. 6 .

On the other hand, when the control panel 210 determines NO in step S112 of FIG. 5 as a result of the recovery diagnosis operation, it proceeds to step S119 of FIG. 5 . In step S119, the control panel 210 outputs a determination result signal indicating that the restoration of the elevator 20 has failed. This signal is transmitted from the communication device 250 to the communication network 30 . The sent determination result signal is received by the communication apparatus 320 as shown in step S120 of FIG. 6, and a determination result is input into the information processing apparatus 360. As shown in FIG. In addition, as shown in step S121 of FIG. 6, the determination result is notified to the remote monitoring center 310 from the information processing apparatus 360, and the result is displayed on the display 331 of the remote monitoring center 310. . When the monitor 334 confirms this display, as shown in step S122 of FIG. 6 , an instruction to stop the operation of the elevator 20 and an announcement operation are performed. In addition, the supervisor 334 dispatches the technician 350 to the building 10 by the telephone 333 to the service center 340 adjacent to the building 10 as shown in step S123 of FIGS. 2 and 6 . instruct to do Further, the information processing device 360 updates the maintenance database 370 and the recovery diagnosis database 380 as shown in steps S117 and S118 of FIG. 6 .

When a determination signal indicating that the elevator 20 has been restored as shown in step S113 of FIG. 5 is input, the information processing device 360 updates the maintenance database 370 as follows.

When a determination signal indicating that the elevator 20 has been restored as shown in step S113 of FIG. 5 is input, the information processing device 360 selects "remote restoration" and restores the failure history data 377 as the restoration method item. "Recovery" is stored in the item of the judgment result. As described above, when the communication device 320 receives the fault signal, the information processing device 360 receives the fault code “0001” input from the communication device 320, the management number of the elevator 20, and a fault occurrence. The date and time is stored in the failure history data 377 of the maintenance database 370 . Accordingly, all items of the failure history data 377 are updated by this restoration method and storage of the restoration determination result.

Also, in this remote recovery, the information processing device 360 refers to the recovery diagnosis database 380, and when the fault code “0001” is the recovery command, the garbage accumulation on the door threshold, which is the most frequent fault factor ( “Door circuit reset + door opening/closing retry” is a recovery command that executes a recovery operation corresponding to the failure factor 1), and “door opening/closing diagnosis” is a recovery diagnostic command that executes a recovery diagnostic operation corresponding to the result of this recovery operation. A recovery diagnostic command set A is selected to execute a recovery operation and a recovery diagnostic operation. Therefore, when the restoration of the elevator 20 is successful, the number of failure code “0001” and failure factor 1 (garbage accumulation on the door sill) of the restoration diagnosis database 380 is increased by one, and the number of cases of successful restoration is increased by one. increase the recovery rate. In addition, the information processing device 360 increases the number of failure factors 1 in the failure code "0001" in the data 378 for each failure factor by one.

On the other hand, when a determination signal indicating that the restoration of the elevator 20 has failed as shown in step S119 of FIG. 5 is input, the information processing device 360 performs the maintenance database 370 and the restoration diagnosis database ( 380) is updated. When a determination signal indicating that the restoration of the elevator 20 has failed as shown in step S119 of FIG. 5 is input, the information processing device 360 sets "remote restoration" to the item of the restoration method of the failure history data 377. , "Fail" is stored in the item of the recovery judgment result. In addition, the number of failure code "0001" and failure factor 1 (garbage accumulation at the door threshold) in the recovery diagnosis database 380 is kept as it is, and the recovery rate is reduced by the number of failures in recovery. In addition, when recovery fails, the number of failure factors 1 in the failure code "0001" in the data 378 for each failure factor is not changed.

In the above description, the case where the information processing device 360 selected the recovery diagnosis command set A based on the failure factor with the largest number of cases corresponding to the failure code "0001" has been described. When the information processing device 360 selects the recovery diagnostic command set B based on the recovery rate of the recovery diagnostic command set corresponding to the fault code “0001”, instead of the recovery operation of “door high-torque opening/closing”, the normal torque The difference is that the restoration operation of "door opening/closing retry" which performs the opening/closing operation of the low doors 13 and 26 again is performed. Other operations are the same as when the recovery diagnostic command set A is selected.

If the remote restoration of the elevator 20 is successful, the number of cases of garbage accumulation on the door sill (failure factor 1), which was the most frequent failure factor in the case of the failure code "0001" until then, increases. For this reason, when the remote recovery system 100 selects the recovery diagnostic command set based on the failure factor with the largest number of cases corresponding to the fault code “0001”, the failure code “0001” may have been input during the next remote recovery. At this time, the information processing device 360 selects the recovery diagnosis command set A again. In addition, when the recovery rate of the recovery diagnostic instruction set A is higher than the recovery rate of the recovery diagnostic instruction set B, the information processing device 360 uses the command with the highest recovery rate among a plurality of commands corresponding to the failure code "0001" as a recovery command. Also in the case of selecting as , the recovery diagnosis command set A is selected.

On the other hand, if the remote recovery of the elevator 20 fails, the number of failure factors 1 of the failure code "0001" in the data 378 for each failure factor does not change, but the recovery rate of the recovery diagnosis command set A decreases. As a result, the recovery rate of the recovery diagnostic command set B is relatively high. That is, the recovery rate ratio of the recovery diagnostic command set B to the recovery diagnostic command set A is increased. When this recovery rate ratio becomes larger than the ratio of the number of cases calculated as the ratio of the number of cases of failure factor 1 to the number of cases of failure factor 2, the information processing device 360 sends the command having the highest recovery rate among a plurality of commands corresponding to the failure code "0001" is selected as the recovery command. For this reason, when the failure code "0001" is input at the time of the next remote recovery, the information processing device 360 selects the recovery diagnostic command set B with the highest recovery rate. In addition, when the information processing device 360 does not select the recovery diagnostic command set A that failed recovery in the previous remote recovery, the failure factor 1 is followed by the failure factor 2 in which the number of cases corresponding to the failure code "0001" is large. Select the linked recovery diagnostic instruction set B.

In addition, when the information processing device 360 selects the recovery diagnostic command set B with the highest recovery rate from among the plurality of commands corresponding to the failure code "0001" and the elevator 20 is successfully restored, the recovery diagnostic command set B recovery rate is increased. Accordingly, in the next remote recovery, the information processing device 360 selects the recovery diagnostic command set B as in the previous time. On the other hand, when recovery of the elevator 20 fails with the recovery diagnostic command set B, the recovery rate of the recovery diagnostic command set B is lowered. Then, when the recovery rate of the recovery diagnosis command set B is lower than the recovery rate of the recovery diagnostic command set A, the information processing device 360 selects the recovery diagnostic command set A. In addition, when the information processing device 360 does not select the recovery diagnostic command set B that failed recovery in the previous remote recovery, recovery diagnostics with a high recovery rate corresponding to the failure code "0001" next to the recovery diagnostic command set B Select command set A.

In this way, if the remote recovery system 100 succeeds in remote recovery, the number of failure factors and the recovery rate of the selected recovery diagnostic command set are increased. In addition, when remote recovery fails, the remote recovery system 100 reduces the recovery rate of the selected recovery diagnostic command set while maintaining the number of failure factors. For this reason, if remote recovery is successful, the possibility that the recovery diagnostic command set selected in the remote recovery will be selected at the next remote recovery increases. In addition, if the remote recovery fails, the possibility that the recovery diagnostic instruction set selected in the remote recovery will be selected at the next remote recovery is lowered. For this reason, as the number of remote recovery increases, the information processing device 360 can select from the recovery diagnostic database 380 a recovery diagnostic command set with a high recovery possibility corresponding to the fault code, and The certainty of recovery can be improved.

In the embodiment described above, the operation of the remote recovery system 100 when a failure code "0001" indicating a failure related to the doors 13 and 26 is output from the control panel 210 has been described. Next, a description will be given of a case in which a failure code "0002" indicating a failure related to the control circuit is output from the control panel 210 . In addition, the description is abbreviate|omitted about the operation|movement similar to the case where the failure code "0001" is output.

If the fault code is “0002” indicating a failure in the control circuit, the technician 350 checks on site, and as a result of the local inspection, the cause for outputting the fault code “0002” is that the relay mounted in the control panel 210 is defective. If there is (fault factor 4), or there is a fault in the relay driving circuit that drives the relay (fault factor 5), or other fault factor 6 or so. The data 378 for each failure factor is 100 cases where a fault in the relay was a factor (failure factor 4), 50 cases where a fault in the relay drive circuit was a factor (failure factor 5), in the case of the fault code "0002", The other failure factors 6 have the same data structure as 10 cases, and the data are arranged in the order of the largest number of cases. As described above, in the case of recovery by the remote recovery system 100, when the recovery of the elevator 20 is successful according to the recovery command, the total number of fault factors corresponding to the fault code as the basis of the recovery command is the total number of cases. is added to the number of failure factors of

As shown in FIG. 7 , the recovery diagnosis database 380 is a database in which the recovery diagnosis command set and the recovery rate are linked to the data 378 for each failure factor. Hereinafter, the data structure of the recovery diagnosis database 380 in the case where the failure code is "0002" indicating a failure related to the control circuit will be described. If the relay is defective (failure factor 4), the recovery diagnostic data includes “control circuit reset + low-speed up/down operation” as a recovery command to the number of fault factor 4 data, and “each floor operation, high-speed operation” as a recovery diagnostic command. It has a data structure in which a recovery diagnostic command set D, which is a set of two commands of "diagnosis", and a recovery rate a% by a recovery operation according to the recovery diagnostic command are linked. If there is a fault in the relay drive circuit (failure factor 5), the recovery diagnostic data is “control circuit reset + operation between the top and bottom floors” as a recovery command to the number of fault factor 5 data, and “each floor operation, It has a data structure in which the recovery diagnostic command set E, which is a set of two commands of "High-speed operation diagnosis", and the recovery rate b% by the recovery operation according to the recovery diagnostic command are linked. Similarly, in the case of the failure factor 6, the recovery diagnostic data has a data structure in which the recovery diagnostic command set F and the recovery rate c% are linked to the number data of the failure factor 6. In this way, the recovery diagnostic database 380 associates a failure code, a failure factor corresponding to the failure code, the number of failure factors, a recovery diagnostic command set, which is a set of recovery commands and recovery diagnostic commands, and a recovery rate. stored in the database. In addition, the recovery rate is the highest in b% of the recovery diagnostic command set E.

When the fault code is "0002", when the information processing device 360 selects the recovery diagnosis command set D based on the failure factor with the largest number of cases corresponding to the fault code "0002", the information processing device 360 , and transmits the recovery diagnostic command set D to the control panel 210 . After executing the control circuit reset operation, the control panel 210 executes low-speed up and down operations for raising and lowering the car 22 of the elevator 20 at a low speed. Thereafter, the control panel 210 executes each floor operation to stop on each floor without opening and closing the doors 13 and 26, a high-speed operation for driving between a plurality of floors at high speed, an operation for stopping each floor, and a high-speed operation Check that there are no abnormalities in driving. The control panel 210 outputs a determination result of successful restoration of the elevator 20 when there is no abnormality in each floor operation and high-speed operation. In addition, when abnormality is detected in each floor operation and high-speed operation, the control panel 210 outputs the determination result that the restoration of the elevator 20 has failed. The determination result is input from the control panel 210 to the information processing device 360 via the communication devices 250 and 320 . As described above, the information processing device 360 includes the failure history data 377, the failure factor-specific data 378, and the recovery diagnostic database so that a recovery diagnostic command set with a higher recovery possibility can be selected based on the determination result. (380) is updated.

Further, when the information processing device 360 selects the recovery diagnostic command set E with the highest recovery rate corresponding to the failure code “0002”, the information processing device 360 sends the recovery diagnostic command set E to the control panel 210 . send After executing the control circuit reset operation, the control panel 210 executes an operation between the lowest floor and the uppermost floor in which the car 22 of the elevator 20 is moved between the lowest floor and the uppermost floor. Next, the control panel 210 executes each floor operation and high-speed operation described above, performs a restoration diagnosis of the elevator 20 , and outputs a determination result of whether restoration of the elevator 20 succeeds or fails. As described above, this determination result is input from the control panel 210 to the information processing apparatus 360 via the communication apparatuses 250 and 320 . The information processing device 360 updates the failure history data 377, the data for each failure factor 378, and the recovery diagnosis database 380 so that a recovery diagnostic command set with a higher recovery possibility can be selected based on the determination result. do.

Next, the case where the failure code is "0003" indicating that the failure is related to the brake will be described.

When the fault code is 0003 indicating a fault related to the brake, as a result of on-site inspection by the technician 350, the factor outputted with the fault code “0003” is the fault of the brake circuit of the control panel 210 (failure factor 7) ) or other failure factors 8 and 9. Therefore, the data 378 for each failure factor is 100 cases where the brake circuit abnormality was a factor (failure factor 7), 50 cases where the failure factor 8 was 50 cases, and 9 other failure factors in the case of the failure code "0003". It has the same data structure as 10 cases, and the data is arranged in the order of the largest number of cases. As described above, in the case of recovery by the remote recovery system 100, when the recovery of the elevator 20 is successful according to the recovery command, the total number of fault factors corresponding to the fault code that is the basis of the recovery command is the total number of cases. is added to the number of failure factors of

As shown in FIG. 8 , the recovery diagnosis database 380 is a database in which the recovery diagnosis command set and the recovery rate are linked to the data 378 for each failure factor. Hereinafter, the data structure of the recovery diagnosis database 380 in the case where the failure code is "0003" indicating a failure related to the brake will be described. When the brake circuit abnormality is a factor (failure factor 7), the recovery diagnostic data includes data on the number of failure factors 7, "control circuit reset" as a recovery command, and "brake torque diagnosis" as a recovery diagnostic command. It has a data structure in which the recovery diagnostic command set G, which is a set, and the recovery rate d% by the recovery operation according to the recovery diagnostic command are linked. In the case of failure factor 8 and failure factor 9, the recovery diagnostic data links the recovery diagnostic command set H and recovery rate e%, and recovery diagnostic command set I and recovery ratio f%, respectively, to the number data of each failure factor 8 and failure factor 9. It is made up of data structure. In this way, the recovery diagnostic database 380 associates a failure code, a failure factor corresponding to the failure code, the number of failure factors, a recovery diagnostic command set, which is a set of recovery commands and recovery diagnostic commands, and a recovery rate. stored in the database. In addition, as for the recovery rate, e% of the recovery diagnosis command set H is the highest.

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

When the failure code is "0003", the information processing device 360 gives a recovery diagnosis command based on the failure factor with the largest number of cases corresponding to the failure code "0003" by the information processing device 360 in step S106 of FIG. 5 . When the set G is selected, the information processing device 360 transmits the recovery diagnosis command set G to the control panel 210 .

When the failure code is "0003", upon receiving this restoration diagnosis instruction set G, the control panel 210 performs a brake torque diagnosis operation in the on-site confirmation shown in step S109 of FIG. 5 . The brake torque diagnosis operation is an operation in which the traction machine in the driving device 24 is not rotated by a mechanical brake, and a driving force is applied to the traction machine to confirm that the traction machine does not rotate by the holding force of the brake. If there is no abnormality in this operation|movement, the control panel 210 announces the remote restoration assuming that the on-site confirmation of the elevator 20 was possible in step S109 of FIG. Thereafter, the flow advances to step S110 of FIG. 5 , and the control panel 210 executes a control circuit reset operation.

After that, the control panel 210 executes a brake torque diagnosis operation. When there is no rotation of the hoisting machine by this operation|movement, the control panel 210 outputs the determination result that restoration of the elevator 20 was successful. In addition, when the hoisting machine rotates, the control panel 210 outputs a determination result that the restoration of the elevator 20 has failed. The determination result is input from the control panel 210 to the information processing device 360 via the communication devices 250 and 320 . The information processing device 360 updates the failure history data 377 , the data for each failure factor 378 , and the recovery diagnosis database 380 so that a recovery diagnostic command set with a high recovery possibility can be selected based on the determination result. .

Also, as described above, the information processing device 360 may select the recovery diagnostic command set H with the highest recovery rate corresponding to the fault code “0003” and cause the control panel 210 to execute the recovery operation and the recovery diagnostic operation. .

In addition, when there is an abnormality in the brake torque diagnosis operation, the control panel 210 determines that remote recovery cannot be started, does not execute the remote recovery operation, and notifies the remote monitoring center 310 of the remote recovery impossibility. .

As described above, when various failures occur in the elevator 20, the remote recovery system 100 responds to a command from the remote recovery device 300 disposed at a location away from the elevator 20 to the elevator 20. The elevator 20 can be restored by executing a restoration operation and a restoration diagnosis operation. For this reason, when a malfunction occurs in the elevator 20, the elevator 20 can be restored in a short time without dispatching the technician 350 to the field, and the operation service of the elevator 20 can be improved.

In addition, the remote recovery system 100 includes failure history data 377 and failure factor-specific data 378 so as to select a recovery diagnostic command set with a higher recovery probability at the time of the next remote recovery based on the recovery determination result. , the recovery diagnosis database 380 is updated. For this reason, as the number of remote recovery increases, the information processing device 360 can select a more appropriate recovery diagnostic command set corresponding to the fault code from the recovery diagnostic database 380 . Thereby, the restoration of the elevator 20 can be performed reliably, and the time required for restoration can be shortened, and the operation service improvement of the elevator 20 can be aimed at.

<Remote diagnosis processing>

As shown in Fig. 2, the information processing device 360 is divided into a function block for executing remote recovery processing and a function block for executing remote diagnosis. The information processing device 360 is a functional block of the latter (remote diagnosis), and includes a similar elevator extraction unit 400 , a diagnostic operation command unit 402 , a maintenance and inspection necessity determination unit 404 , and a threshold value change unit 406 . ), a diagnostic driving schedule setting unit 408 , a temporary abnormality setting unit 410 , and a diagnostic driving item database 412 . Also, during remote diagnosis, various data of the maintenance database 370 are used. From such a viewpoint, the remote recovery apparatus 300 according to the present embodiment also has a function as a remote monitoring apparatus.

9 and 10, flowcharts of remote diagnosis processing by the remote recovery device 300 (remote monitoring device) are exemplified. Steps S101 to S104 have the same contents as the same code steps in Fig. 5, and therefore description thereof is omitted. Since the steps in Fig. 5 are partially overlapped, the remote diagnosis processing according to the present embodiment can be said to be a processing flow branched from the remote recovery processing.

In addition, in the following description, the example when the elevator 20 of the origin of a failure signal is the elevator 20A and the similar elevator is the elevator 20B is demonstrated.

In step S104, when the failure content of the elevator 20 (20A) is that remote recovery is not possible, a security check in which a technician (security guard) runs to the elevator 20A is required for recovery, and the process proceeds to step S1002 . In addition, about the normal security check by legal inspection etc., the security check based on a failure is appropriately called an emergency security check hereinafter.

When the failure contents of the elevator 20 are remotely recoverable, the diagnostic operation command unit 402 of the information processing device 360 sends the elevator control device 200A of the elevator 20A that is the source of the failure signal (of The control panel 210A) waits for the recovery determination result of the remote recovery operation (S113 in Fig. 5). When the recovery judgment result is transmitted from the elevator control device 200A to the information processing device 360 via the communication devices 250A and 320, the diagnostic operation command unit 402 of the information processing device 360 sends the recovery judgment result to the It is determined whether the recovery has failed (S1000).

When the recovery determination result is recovery success, the emergency security check becomes unnecessary, and the remote diagnostic processing flow ends (FIG. 10). On the other hand, when the restoration determination result is restoration failure, since an emergency security check is required for restoration of the elevator 20A, the flow advances to step S1002.

In step S1002, the elevator 20A of remote recovery failure or remote recovery failure, i.e., similar to the elevator 20A requiring maintenance and inspection, in other words, an elevator 20 (similar elevator) whose failure is predicted later is extracted. As will be described later, by extracting a similar elevator and performing remote diagnosis, it is determined whether an emergency security check is necessary for the similar elevator.

When extracting the similar elevator, the similar elevator extraction unit 400 of the information processing device 360 refers to the data stored in the maintenance database 370 . Specifically, the similar elevator extraction unit 400 extracts the similar elevator based on the elevator specification data 371 (specification storage unit) of the maintenance database 370 .

As shown in Fig. 3, various specification items are stored in elevator specification data 371 (specification storage unit). The similar elevator extraction unit 400 extracts the elevator 20A as the source of the failure signal and the elevator 20 in which at least one of the specification items is common as the similar elevator.

For example, among the specification items of the elevator specification data 371 (specification storage unit) illustrated in FIG. 3 , the elevator management number and the manufacturing number are unique to the elevator, and therefore are not basically common between the elevators 20 . There is a possibility that 6 items of the remaining model, manufacturing date, installation building name, installation building use, installation environment, and number of times of rope bending are common among elevators 20 . The similar elevator extraction unit 400, from the elevator specification data 371, calls the specification data of the elevator 20A of the origin of the failure signal, and similarly compares the elevator 20 in which at least one of the specification items is common. It is extracted as an elevator.

In addition to the elevator specification data 371 (specification storage unit), other data of the maintenance database 370, for example, the elevator ( 20) may be extracted as a pseudo elevator.

Here, you may make it advance the execution order of the remote diagnosis mentioned later, so that there are many items common with each item of the elevator 20A. In addition, a weighted score may be given to each specification item, and the execution order of remote diagnosis may be determined based on the total score. This score may be changed according to the failure code.

For example, when the fault code indicates the control panel 210A, that is, when the faulty device is the control panel 210A, even if the number of rope bending is common in the elevator 20A and the other elevators 20, the faulty device (control panel) (210A)), since it cannot be said to be an important common point, the weight of the score is relatively low. On the other hand, when the fault code indicates the wire 23A, the weight of the score of the number of times of rope bending becomes relatively high. In this way, the storage unit (not shown) of the information processing device 360 may store the score of each item in the maintenance database in association with the failure code.

When the extraction of the similar elevator is completed, the temporary abnormality setting unit 410 refers to the diagnostic operation item database 412 and sets the temporary abnormality flag of the elevator management number extracted as the similar elevator in step S1002 to "valid" ( S1004).

11 shows the remote diagnosis setting data for the elevator management number 123456 among the data stored in the diagnosis operation item database 412 . In this database, diagnostic items at the time of remote diagnosis, specific diagnosis contents, and judgment threshold values are set.

A diagnosis item is determined according to the customer's request etc. who delivered the elevator 20, for example. In addition, the diagnosis content and the judgment threshold value are determined by the specification of the elevator 20, the date of manufacture, and the like. The judgment threshold is divided into three categories: normal, modulated, and abnormal, and these classifications are distinguished by the judgment threshold.

In addition, in the diagnostic operation item database 412, it is possible to set the enable/disable switching of the temporary abnormal flag. As described above, the temporary abnormality setting unit 410 sets the temporary abnormality flag to valid for the similar elevator.

Also, in the diagnostic operation item database 412, the execution scheduled date and time of the remote diagnostic operation is set in advance. This setting date and time is changed by the diagnostic operation schedule setting unit 408 when it is set to a similar elevator. For example, the scheduled execution date and time of the remote diagnosis operation is changed immediately after extraction as a pseudo elevator in step S1002.

The threshold value change unit 406 refers to the diagnostic operation item database 412 and changes the determination threshold value of the elevator management number (similar elevator) for which the temporary abnormality flag is set to be valid (S1006). Specifically, as illustrated in FIG. 12 , the determination threshold for classifying a normal value, a modulation value, and an abnormal value is raised to the normal value side. In other words, the threshold is changed so that the judgment becomes stricter.

As described above, similar elevators have similar specifications and equipment to those of the broken equipment, and even if they are currently in a normal or tampered state, there is a possibility that they will fail in the near future. Therefore, in the remote diagnosis for a similar elevator, the judgment threshold value of diagnosis is made strict, and equipment exchange is performed if there is a sign of a failure even in the slightest.

The diagnostic operation command unit 402, via the communication devices 320 and 250 (250B), in response to the execution date and time of the remote diagnostic operation being changed to the current time, the control panel 210 (for example, 210B) of the similar elevator A remote diagnostic operation execution command is transmitted to (S1008). In addition, the diagnostic items of the remote diagnostic operation, the contents of the diagnosis, and the judgment threshold value are transmitted to the control panel 210B together with the execution command of the remote diagnostic operation. Also, at this time, the determination threshold value changed (strictly viewed) by the threshold value changing unit 406 is used as the determination threshold value of the diagnostic operation. In addition, the diagnostic item, the diagnostic content, and the judgment threshold value may only be related to the trouble code transmitted in step S102.

The control panel 210B receives an execution command for remote diagnostic operation and a diagnostic item transmitted in response thereto, and executes the diagnostic operation (S1010). In addition, prior to the diagnosis operation, assuming that there are users around, an announcement may be made to the effect of moving away from the platform. Alternatively, the diagnostic operation may be performed after guiding the passengers in the car to the nearest floor and leaving them out of the car.

Each diagnostic item of the diagnostic operation is determined by the control panel 210B. In all the diagnostic items, when the detected value is included in the normal region, the control panel 210B and the communication device 250B transmit a diagnosis result indicating that the detection is normal (S1012). The communication device 320 receives this and sends it to the information processing device 360 .

On the other hand, when the detection value is included in the abnormal area in a certain diagnostic operation result in step S1010, the control panel 210B and the communication device 250B determine abnormality as a result of the diagnosis that there is an abnormality, and the device and its detection value (abnormal value) transmits (S1012). The communication device 320 receives this and sends it to the information processing device 360 .

The maintenance check necessity determination unit 404 acquires the diagnosis result transmitted from the control panel 210B, and determines whether the result is normal (S1014 in FIG. 10). In a normal case, the maintenance check necessity determination unit 404 determines that the emergency maintenance check is unnecessary (S1016). Upon receiving this, the temporary abnormality setting unit 410 switches and sets the temporary abnormality flag from valid to invalid (S1018). In addition, the information processing device 360 transmits the determination result (normal) to the remote monitoring center 310 (S1020). In addition, the contents and results of the diagnostic operation at this time are stored in the remote inspection history data 374 . In addition, the information processing device 360 sends a command to the control panel 210B to switch the operation of the pseudo elevator 20B from the diagnostic operation to the normal operation (S1022).

Next, the diagnostic operation schedule setting unit 408 sets the date and time of the next remote diagnostic operation (S1024). For example, for the pseudo elevator 20B, the date and time of the next remote diagnosis operation is set at an interval (eg, once a week) shorter than a predetermined normal interval (eg, once a month). Thereby, it becomes possible to monitor the state change of the equipment of the similar elevator 20B in which the malfunction was reported by the other elevator 20A at shorter time intervals.

On the other hand, when the diagnosis result transmitted from the control panel 210B in step S1014 is an abnormal determination, that is, when a detection value is included in an abnormal area in a certain diagnostic operation result, the maintenance and inspection necessary determination unit 404 determines that an emergency inspection is performed. It is determined as necessary (S1026).

Upon receiving the determination, the information processing device 360 transmits the determination result (eg, abnormality determination, abnormality determination target device, and abnormal value) to the remote monitoring center 310 ( S1028 ). In addition, the diagnostic operation contents and results at this time are stored in the remote inspection history data 374 .

In addition, the monitor 334 of the remote monitoring center 310 makes an instruction to stop the operation of the elevator 20B and an announcement operation through the communication devices 320 and 250B and the control panel 210B (S1030). Then, the supervisor 334 instructs the service center 340 near the building 10B by the phone 333 to dispatch the technician 350 (security guard) to the building 10B to execute an emergency security check. (S1032).

Moreover, when the remote monitoring center 310 receives the determination result (abnormality) in step S1028, the apparatus determined abnormally is also received together. From this, the supervisor 334 of the remote monitoring center 310 may place an order for replacement parts, ie, replacement parts for a malfunctioning device, from a material center (not shown) or the like together with the execution instruction of the emergency security check. In addition, the supervisor 334 registers the replacement operation of the malfunctioning device in the inspection item of the emergency maintenance inspection.
