And the door 105a provided in the landing 105 opens and closes in conjunction.

The elevator 101 includes a door opening / closing sensor (not shown) that detects opening / closing of the doors 102c and 105a. The output of the door open / close sensor changes depending on whether the doors 102c and 105a are open or closed. The door opening / closing sensor can be realized by, for example, a micro switch or a photoelectric sensor. The door opening / closing sensor is connected to the control board 110 via wiring, and a signal output from the door opening / closing sensor is input to the control board 110 via the wiring.

Each platform 105 is provided with an operation panel 105b provided with a platform call button (not shown), a display for displaying the floor where the basket 102 is located, and the like. Each operation panel 105b provided in each platform 105 includes a control board for the operation panel 105b, and is connected to the control board 110 via the control board for the operation panel 105b.

The remote monitoring support device 120 can be attached to, for example, a housing that houses the control board 110 of the elevator 101, a wall of a hoistway, or the like. The remote monitoring support device 120 includes a main control board 121 and a voice communication board 122. The main control board 121 is connected to the control board 110.

The main control board 121 is connected to a connection terminal 121a connected to the control board 110. The connection terminal 121a can be realized by, for example, a connector connected to the main control board 121 via the wiring 121b or the like. The remote monitoring support device 120 is provided on the control board 110 and connects the connection terminal 121a to a terminal 110a (hereinafter referred to as “maintenance / inspection terminal”) 110a to which a diagnostic terminal device can be connected. Thus, the control board 110 is connected. The connection terminal 121a and the maintenance inspection terminal 110a are detachably connected.

The maintenance inspection terminal 110a is used, for example, to connect a diagnostic terminal device (maintenance diagnosis terminal) used for the maintenance inspection work when the worker performs the maintenance inspection work at the site where the elevator 101 is installed. Is provided. The terminal 110a for maintenance and inspection is not limited to the elevator 101 installed for the purpose of remote monitoring, and a wide variety of elevators 101 are generally provided regardless of whether the existing equipment is new or old.

The terminal device for diagnosis has portability that can be carried by an operator, and is used, for example, for maintenance inspection work that is performed on the site where the elevator 101 is installed. The diagnostic terminal device includes a terminal that is detachably connected to the maintenance inspection terminal 110a. In the maintenance / inspection work, the worker connects a terminal included in the diagnostic terminal device to a maintenance / inspection terminal provided on the control board 110, and performs a predetermined input operation on the diagnostic terminal device. The diagnostic terminal device outputs a signal corresponding to the input operation by the worker to the control board 110.

For example, when a signal output from a diagnostic terminal device is input during maintenance / inspection work, the control board 110 operates each unit in the elevator 101 according to the input signal, and diagnoses a signal related to the operation result. Output to the terminal device. The diagnostic terminal device reports information for guiding whether or not the elevator 101 has operated normally in response to an input operation by an operator, based on a signal relating to the operation result of the elevator 101 output from the control board 101. .

The main control board 121 is connected to the management server computer 130 via a network 160 such as the Internet. By connecting the main control board 121 and the management server computer 130 via the Internet instead of the public voice network 170 such as a telephone line, the situation of the elevator 101 is prevented from being delayed due to the puncture of the telephone line in an emergency. And can respond quickly.

The voice communication board 122 is connected to the interphone terminal device 102b and the public voice network 170. Specifically, the voice communication board 122 can be realized by a PHS (Personal Handy-phone System) board, for example. Public voice network 170 includes a fixed telephone network (public switched telephone network) and a mobile telephone network. The public voice network 170 is composed of a plurality of exchanges (not shown) such as a subscriber line exchange that accommodates telephone lines, a relay exchange that bundles the subscriber line exchanges, and a gateway exchange that is connected to the telephone network of another operator. Yes. Since the public voice network 170 is a known technique, the description thereof is omitted.

The main control board 121 may perform communication using a PHS board included in the voice communication board 122. In this case, the remote monitoring support device 120 uses the PHS board for voice communication as well as data communication. Since the installation location of the elevator 101 is fixed, by performing communication using PHS, it is possible to secure the communication quality and to reduce the cost for communication.

The management server computer 130 can be realized by a computer device such as a personal computer, for example. An operation terminal device 131 may be connected to the management server computer 130. The management server computer 130 and the operation terminal device 131 may be installed in the same place or in different places. One or more terminal devices 131 may be used for operation. The operation terminal device 131 can be realized by, for example, a computer device such as an input device such as a keyboard or a mouse, or a personal computer equipped with a display. Further, a printer (not shown) for outputting a report describing the state of the elevator 101 may be connected to the operation terminal device 131.

In the maintenance management company 150, in addition to the management server computer 130 and the telephone set 140, a PBX (Private Branch exchange, see reference numeral 205 in FIG. 2) can be installed. The telephone 140 is connected to the public voice network 170 via PBX. In the remote monitoring system 100, the telephone 140 may be directly connected to the public voice network 170 without providing the PBX.

(Hardware configuration of remote monitoring system 100)
Next, a hardware configuration of the remote monitoring support device 120 constituting the remote monitoring system 100 according to the embodiment of the present invention will be described. FIG. 2 is an explanatory diagram showing a hardware configuration of the remote monitoring support device 120 constituting the remote monitoring system 100 according to the embodiment of the present invention.

In FIG. 2, the control board 110 controls the operation of the elevator 101 by driving and controlling each part of the elevator 101. The control board 110 outputs a control signal to each part of the elevator 101 and controls the operation of the elevator 101 based on the signal output from each part.

The control board for the operation panel 102a described above generates a call signal corresponding to the input operation every time an input operation to the operation button by a user of the elevator 101 or the like is received, and outputs the generated call signal to the control board 110. To do. The control board 110 controls the operation operation of the elevator 101 by outputting a control signal for driving and controlling the drive mechanism 104 based on, for example, a call signal output from the control board for the operation panel 102a.

Specifically, the control board 110 generates, for example, a control signal for a motor that raises and lowers the car 102 based on a call signal output from the control board for the operation panel 102a, and the generated control signal. Is output to a motor that moves the car 102 up and down. Thereby, the motor which raises / lowers the cage 102 is rotationally driven in a direction to raise or lower the cage 102. The motor that raises and lowers the car 102 is controlled using, for example, an inverter, and is driven and controlled by the control board 110 so as to stop the rotation on the floor where the car 102 is stopped.

In addition, each time the control board 110 outputs a control signal to the motor that moves the car 102 up and down, the control board 110 acquires the number of rotations of each motor operated according to the control signal. The number of rotations of each motor can be acquired using, for example, an encoder. As a result, the control board 110 can determine whether or not the motor has operated normally in accordance with a control signal output to the motor that moves the car 102 up and down.

Specifically, for example, the control board 110 is used for control to operate a brake so as to stop the car 102 on a predetermined floor based on a call signal output from the control board for the operation panel 102a. A signal is generated, and the generated control signal is output to the brake. The brake operates in accordance with a control signal output from the control board 110 to stop the raising / lowering operation of the car 102 and to stop the car 102 on a predetermined floor. Thereby, the basket 102 can be stopped on a predetermined floor.

Further, whenever the control board 110 outputs a control signal to the brake, the control board 110 acquires an output signal from a brake sensor whose output changes according to the operation of the brake. The brake sensor can be realized by, for example, a micro switch or a photoelectric sensor. Thereby, the control board 110 can determine whether or not the brake has operated normally according to the control signal output to the brake.

Specifically, for example, the control board 110 controls to open and close the doors 102c and 105a on the floor where the basket 102 is stopped by a brake based on a call signal output from the control board for the operation panel 102a. And the generated control signal is output to a motor that opens and closes the door 102c of the car 102 and the door 105a of the landing 105. Thereby, the doors 102c and 105a can be opened and closed on the floor where the basket 102 is stopped. As described above, since the motor that opens and closes the door 105a is locked by a device called an interlock or the like, the motor does not operate when the door 105a is not completely closed.

The control board 110 acquires an output signal from the door opening / closing sensor each time a control signal is output to the motor that opens and closes the doors 102c and 105a. As a result, the control board 110 can determine whether or not the doors 102c and 105a are operating normally according to a control signal output to the motor that opens and closes the corresponding doors 102c and 105a.

Specifically, for example, the control board 110 outputs a control signal including a floor signal indicating the floor on which the car 102 is located to the control board for the operation panel 102a. The floor on which the car 102 is located can be specified based on, for example, an output signal from a sensor (not shown) provided for each floor in the hoistway. When the control board for the operation panel 102a receives a control signal including a floor signal, the control board controls the display unit based on the received control signal, and the floor where the cage 102 is located and the moving direction (ascending) Or is it going down).

The control board 110 outputs a control signal including a floor signal to the control board for the operation panel 102a and the control board for the operation panel 105b, for example, whenever the position of the car 102 is switched. Alternatively, the control board 110 periodically outputs a control signal including a floor signal to the control board for the operation panel 102a and the control board for the operation panel 105b regardless of the position of the cage 102, for example. You may do.

Like the control board for the operation panel 102a, the control board for the operation panel 105b generates a call signal corresponding to the input operation every time an input operation to the landing call button by a user of the elevator 101 is received, The generated call signal is output to the control board 110. When the call signal is output from the control board for the operation panel 105b, the control board 110 is output from the control board for the operation panel 105b in the same manner as when the signal is output from the control board for the operation panel 102a. Based on the signals, various control signals are generated, and the generated control signals are output to the corresponding units to control the operation of the elevator 101.

Specifically, the control board 110 indicates that each time the cage 102 is moved up and down according to a signal output from the operation panel 102a or the operation panel 105b, each unit is activated to move the cage 102 up and down. Output start signal. For example, when the control board 110 moves from the first floor to the second floor, it outputs the activation signal once. Specifically, for example, when the control board 110 moves from the first floor to the fifth floor without stopping on the way, the control board 110 outputs the activation signal once. Further, for example, when the control board 110 moves from the first floor to the fifth floor after stopping on the third floor in the middle (opening / closing the door), the control board 110 outputs the activation signal twice.

The control board 110 may calculate the travel distance and travel time of the car 102 each time the car 102 is moved up and down. The travel distance of the basket 102 can be calculated based on, for example, the number of activations. Further, the traveling time of the car 102 can be calculated based on the floor signal, for example. Specifically, for example, when a call operation is received from the operation panel 105b of the fourth-floor platform 105 with the basket 102 on the first floor, the basket 102 moves from the first floor to the fourth floor for the third floor. To do.

The control board 110 includes a memory (not shown) and stores the number of times the activation signal is output, that is, the number of activations, in the memory every time the activation signal is output. The control board 110 may store, in the memory, the history of operation of each unit driven during the raising / lowering operation of the car 102 or the opening / closing operation of the doors 105a and 102c, instead of or in addition to the number of activations. Specifically, the control board 110 relates to, for example, the number of activations, the travel distance of the car 102, the travel time of the car 102, the number of operations of various relays that are operated when the car 102 is raised and lowered, and the doors 105a and 102c are opened and closed. Information may be stored in the memory as a history of operation.

Further, the control board 110 determines whether the doors 102c and 105a are open or closed based on the output value of the door open / close sensor. The control board 110 outputs a control signal for opening / closing the doors 102c, 105a based on a control signal for opening / closing the doors 102c, 105a output by itself and an output value of the door opening / closing sensor. It can be determined whether or not the doors 102c and 105a are actually opened and closed.

In addition, when the operation mode of the elevator 101 changes, the control board 110 outputs a signal indicating that the operation mode has been switched. Specifically, for example, when the operation mode of the elevator 101 is switched from the normal operation mode to an operation mode other than the normal operation mode, the control board 110 informs the outside that the operation mode has been switched. A signal to notify or a signal to notify the operation mode after switching (that is, an operation mode other than the normal operation mode) is output. Specifically, the control board 110 indicates that, for example, when the operation mode of the elevator 101 is switched from an operation mode other than the normal operation mode to the normal operation mode, the operation mode is switched. A signal to notify to the outside or a signal to notify the operation mode after switching (the normal operation mode) (report signal) is output.

Further, when the control board 110 detects a failure in the elevator 101, the control board 110 outputs (reports) a signal (report signal) notifying the occurrence of the problem. Specifically, for example, although the control board 110 outputs a control signal for opening and closing the doors 105a and 102c, the corresponding doors 105a and 102c do not operate based on the output value of the door opening / closing sensor. When this is detected, a signal (report signal) notifying that a failure has occurred in the corresponding doors 105a and 102c in the elevator 101 is output (reported).

When the call button is operated, the interphone terminal device 102b outputs a call signal indicating that the operation has been performed to the remote monitoring support device 120. When the call signal output from the interphone terminal device 102 b is input to the voice communication board 122, the remote monitoring support device 120 transmits the call signal to the telephone 140 via the public voice network 170 or the PBX 205. Thus, voice communication (call) can be performed between the interphone terminal device 102b and the telephone 140.

The interphone terminal device 102b remotely monitors the voice signal input to the microphone in a state where the connection between the remote monitoring support device 120 (voice communication board 122) and the telephone set 140 installed in the maintenance management company 150 is established. The data is output to the support device 120. Further, the interphone terminal device 102b receives the audio signal output from the remote monitoring support device 120 via a speaker in a state where the connection between the remote monitoring support device 120 (voice communication board 122) and the telephone 140 is established. Output.

The remote monitoring support device 120 acquires a control signal output from the control board 110 to each unit included in the elevator 101, generates notification information based on the acquired control signal, and generates the generated notification information. It transmits to the management server computer 130. The notification information includes information related to the state of the elevator 101, identification information of the elevator 101 that is the transmission source of the notification information, and the like.

Information about the state of the elevator 101 includes, for example, the direction in which the car 102 is moved up and down, the floor to which the car 102 is moved, whether the car 102 has stopped on the floor to which the car 102 is moved, and the motor that opens and closes the doors 105a and 102c. Indicates the presence or absence of the operation. Moreover, the information regarding the state of the elevator 101 indicates, for example, the floor where the car 102 is currently located, whether or not various safety devices are activated, and the like.

The identification information of the elevator 101 may be, for example, the manufacturing number of the elevator 101, a number set based on the installation location (address, etc.) of the elevator 101, It may be a number arbitrarily set by an operator who performs maintenance and inspection. The identification information of the elevator 101 can be configured by combining characters such as numbers having a predetermined number of digits and alphabets.

The main control board 121 provided in the remote monitoring support device 120 can be constituted by, for example, a relay board 201, a monitoring control board 202, a memory 203, and a communication I / F (interface) 204. The communication I / F 204 controls input / output of information to / from the remote monitoring support device 120 with the management server computer 130.

A connection terminal 121 a connected to the control board 110 is connected to the relay board 201. The connection terminal 121a is not limited to being provided integrally with the relay substrate 201. The connection terminal 121a may be electrically connected to the relay board 201 (input terminal thereof), for example, by a connector provided separately from the relay board 201 and connected to the relay board 201 by wiring. Can be realized.

The remote monitoring support device 120 can be connected to the control board 110 by connecting the connection terminal 121a to the maintenance / inspection terminal 110a provided in the control board 110, for example. When the maintenance inspection terminal 110a and the connection terminal 121a are realized by connectors, the connection terminal 121a and the maintenance inspection terminal 110a can be connected to each other so that an operator or the like can be arbitrarily separated.

Specifically, for example, by inserting and removing a connector (male or female) that realizes the connection terminal 121a into a connector (female or male) that realizes the terminal 110a for maintenance and inspection, the remote monitoring support device 120 and the control board 110 can be connected or disconnected.

Alternatively, the remote diagnosis scheduled date and time related to the diagnosis instruction is stored.

The processing upon completion of the reservation diagnosis is not limited to storing the completion information in association with the diagnosis instruction corresponding to the diagnosis operation corresponding to the diagnosis instruction related to the single reservation or the scheduled date and time of remote diagnosis. Processing at the time of completion of reservation diagnosis is realized by adding completion information as appropriate in association with the corresponding diagnosis instruction and remote diagnosis scheduled date and time each time a diagnosis operation corresponding to a diagnosis instruction concerning repeated reservation is completed. May be. In this way, each time the diagnostic operation corresponding to the diagnostic instruction related to the repeated reservation is completed, the remote monitoring support device 120 adds and stores the completion information in association with the corresponding diagnostic instruction and the scheduled remote diagnosis date and time. Since the set reservation date and time remains in the terminal, the maintenance diagnosis terminal can be connected after the corresponding diagnostic operation is completed, and the completion history of the diagnostic operation can be referred to.

The execution instruction generation unit 323 instructs the control board 110 to stop the basket 102 of the elevator 101 to all floors (hereinafter referred to as “all floor stop instruction” as appropriate), and the basket 102 from the lowest floor to the highest floor. An instruction for non-stop movement (hereinafter referred to as “non-stop upward movement instruction” as appropriate), an instruction for non-stop movement of the cage 102 from the highest floor to the lowest floor (hereinafter referred to as “non-stop downward movement instruction” as appropriate), A diagnostic operation execution instruction including the above is generated. The all floor stop instruction includes an instruction to open and close the door 102c of the car 102 and the door 105a of each landing 105.

The diagnosis operation execution instruction is the same as the signal output from the operation panel 102a or the operation panel 105b when an input operation for instructing movement to a predetermined floor is received on the operation panel 102a or the operation panel 105b, for example. It can be realized by a signal (call signal or the like). Specifically, the execution instruction is, for example, moving the basket 102 of the elevator 101 to a predetermined floor, stopping the moved basket 102 on the corresponding floor, A signal for opening and closing the door 102c and the door 105a of the hall 105 is included.

The output unit 324 outputs the diagnosis operation execution instruction for diagnosing the operation state of the elevator to the control board 110 that controls the operation of the elevator when the reception unit 322 receives the diagnosis instruction. Specifically, the output unit 324 outputs the diagnostic operation execution instruction generated by the execution instruction generation unit 323 to the control board 110 when the reception unit 322 receives the diagnostic instruction.

The control board 110 that has received the diagnostic operation execution instruction performs a diagnostic operation in accordance with the received diagnostic operation execution instruction. Specifically, the control board 110 that has received the diagnostic operation execution instruction stops the baskets 102 of the elevator 101 to all floors according to the instructions included in the diagnostic operation execution instructions, Each part of the elevator 101 is driven and controlled so as to move without stopping from the highest floor to the highest floor or to move the car 102 without stopping from the highest floor to the lowest floor.

The acquisition unit 325 acquires a signal input / output from / to the control board 110 in accordance with the diagnostic operation execution instruction output from the output unit 324. For example, the acquisition unit 325 acquires a control signal (downward signal) output from the control board 110 to each unit included in the elevator 101 in accordance with the diagnostic operation execution instruction output from the output unit 324. In addition, the acquisition unit 325 outputs, for example, signals (uplink signals) output from each unit included in the elevator 101 that operates in response to a control signal (downlink signal) output from the control board 110 and input to the control board 110. ) To get.

Time measuring unit 326 measures various times. The timer 326 measures, for example, the elapsed time after the receiving unit 322 receives the diagnosis instruction, the elapsed time after the output unit 324 outputs the diagnosis operation execution instruction, and the like.

The determination unit 327 determines whether or not a predetermined time has elapsed after the output unit 324 outputs the diagnostic operation execution instruction and before the acquisition unit 325 acquires the signal. The determination unit 327 determines whether or not a predetermined time has elapsed after the output unit 324 outputs a diagnostic operation execution instruction and before the acquisition unit 325 acquires a signal, based on the elapsed time counted by the time measurement unit 326. can do.

For example, the determination unit 327 receives the input of the diagnostic operation execution instruction output from the output unit 324, operates normally according to the diagnostic operation execution instruction, and enters the control board 110 during the operation. The time required to normally acquire the output signals (upstream signal, downstream signal) is set as a predetermined time, and the predetermined time before the acquisition unit 325 acquires the signal after the output unit 324 outputs the diagnostic operation execution instruction. Determine whether time has passed. That is, the determination unit 327 determines whether or not a predetermined time has passed without the acquisition unit 325 acquiring a signal after the output unit 324 outputs the diagnostic operation execution instruction.

In response to each instruction included in the diagnostic operation execution instruction output from the output unit 324, the determination unit 327 outputs signals (uplink signals and downlink signals) input / output to / from the control board 110 from the predetermined time. It is determined whether or not everything has been acquired before the time has elapsed. Specifically, for example, when the diagnostic operation execution instruction output by the output unit 324 includes an all-floor stop instruction, a non-stop ascending movement instruction, and a non-stop descending movement instruction, the determination unit 327 includes an all-floor stop instruction, It is determined whether or not all signals (upward signals and downward signals) input to and output from the control board 110 have been acquired in response to the non-stop upward movement instruction and the non-stop downward movement instruction.

As a situation where the predetermined time elapses without the acquisition unit 325 acquiring a signal after the output unit 324 outputs the diagnostic operation execution instruction, for example, during execution of the diagnostic operation corresponding to the diagnostic operation execution instruction, the elevator 101 A situation is assumed in which an input operation to an operation button on the operation panel 102a or a landing call button on the operation panel 105b is received by a user or the like. When the control board 110 receives an input operation to any of the operation buttons during the execution of the diagnostic operation according to the disconnection operation execution instruction, the control board 110 interrupts the diagnostic operation and performs an operation according to the received input operation.

When the determination unit 327 determines that a predetermined time has passed after the output unit 324 outputs a diagnostic operation execution instruction and before the acquisition unit 325 acquires a signal, the output unit 324 determines the predetermined value from the determination. After the waiting time elapses, the diagnostic operation execution instruction is output again. When a predetermined time has elapsed without the acquisition unit 325 acquiring a signal after the output unit 324 outputs a diagnostic operation execution instruction, the time measuring unit 326 continues to count the elapsed time. Accordingly, the output unit 324 can re-output the diagnostic operation execution instruction after a predetermined waiting time has elapsed from the above determination based on the elapsed time counted by the time measuring unit 326.

In this embodiment, the predetermined standby time can be arbitrarily set by the administrator of the remote monitoring support system 100 such as “30 minutes” or “1 hour”, for example. The predetermined waiting time can be, for example, a time estimated to be required until the operation corresponding to the input operation causing the interruption is completed after the diagnosis operation is interrupted.

When the output unit 324 re-outputs the diagnostic operation execution instruction and determines that the predetermined time has elapsed before the acquisition unit 325 acquires a signal corresponding to the re-output diagnostic operation execution instruction, After a predetermined waiting time has elapsed from this determination, the execution instruction is re-output (re-output). The output unit 324 may change the interval for re-outputting the execution instruction when the re-output of the diagnostic operation execution instruction is performed a predetermined number of times continuously.

Specifically, for example, the diagnostic operation execution instruction is re-output twice with a predetermined waiting time of 30 minutes (the diagnostic operation execution instruction is output three times), and the third diagnostic operation execution instruction is output (second time) The output unit 324 determines that the predetermined time has elapsed before the acquisition unit 325 acquires a signal corresponding to the re-output diagnostic operation execution instruction. After a time longer than 30 minutes (for example, “3 hours”, “20 hours”, etc.) has elapsed since the diagnosis operation execution instruction was output, the fourth diagnosis operation execution instruction is output.

More specifically, in this case, the output unit 324 outputs the second diagnostic operation execution instruction after 30 minutes from the output of the first diagnostic operation execution instruction according to the diagnostic instruction received by the receiving unit 322. Output again. Then, after 30 minutes have passed since the second diagnostic operation execution instruction is output again, the third diagnostic operation execution instruction is output again. Thereafter, after the third diagnostic operation execution instruction is output again, after the elapse of 3 hours, the fourth diagnostic operation execution instruction is output again. Further, in this case, the output unit 324 outputs the diagnosis operation execution instructions for the fifth time, the sixth time,... (Re-output) every 3 hours after the previous diagnosis operation execution instruction is output again. May be.

In addition, the output unit 324 may output information on the service person's dispatch request when the execution instruction is re-output for a predetermined number of times. Specifically, for example, when the diagnostic operation execution instruction is output four times without the acquisition unit 325 acquiring a signal according to the re-output diagnostic operation execution instruction, the fifth diagnostic operation execution instruction is not output, Outputs information related to the dispatch of service personnel. In this situation, the output unit 324, when the acquisition unit 325 does not acquire a signal corresponding to the diagnostic operation execution instruction re-output even after a predetermined time has passed since the fourth diagnostic operation execution instruction is output, Outputs information related to the dispatch of service personnel.

Information related to the service man's dispatch request is output to the management server computer 130, for example. Alternatively, the information regarding the service man's dispatch request may be output to, for example, a mobile phone carried by a service man who is in charge of maintenance of the corresponding elevator 101. The output of the information related to the call-out request to the portable telephone carried by the service person is realized by storing in advance the e-mail address assigned to the portable telephone carried by the corresponding service person in the storage unit 321. be able to.

The response information generation unit 328 generates response information based on the signal acquired by the acquisition unit 325. As described above, the response information is information indicating whether or not each unit included in the elevator 101 has normally operated in accordance with the diagnostic operation execution instruction output to the control board 110, and is normal among the units included in the elevator 101. It contains information indicating the location that did not work and the content of the problem.

The response information generation unit 328 generates response information each time a signal corresponding to the diagnostic operation execution instruction output by the output unit 324 is acquired, for example. Further, the response information generation unit 328 may generate response information when, for example, each unit included in the elevator 101 does not perform a normal operation according to the diagnostic operation execution instruction output by the output unit 324.

The response information transmission unit 329 transmits the response information generated by the response information generation unit 328 to the management server computer 130. For example, the response information transmission unit 329 transmits the response information to the management server computer 130 every time the response information generation unit 328 generates the response information.

Further, in step S402, a diagnosis instruction including information specifying whether the reservation is a single reservation or a repeated reservation may be generated. For example, if the diagnostic operation that received the input operation in step S401: Yes is a diagnostic operation related to a single reservation, in step S402, a diagnosis that includes information specifying the specific scheduled remote diagnosis date and time received in the input operation Generate instructions. Further, for example, when the diagnostic operation that received the input operation in step S401: Yes is a diagnostic operation related to repeated reservation, in step S402, the remote monitoring support device 120 that received the input operation periodically performs a diagnosis. A diagnostic instruction including information for designating a scheduled remote diagnosis date and time for performing the operation is generated.

Next, the diagnostic instruction generated in step S402 is transmitted to the corresponding remote monitoring support device 120 (step S403). In step S403, based on the diagnostic instruction generated in step S402, the diagnostic instruction is transmitted to the elevator 101 identified by the identification information of the elevator 101 included in the diagnostic instruction.

Then, it is determined whether or not the response information transmitted in response to the diagnosis instruction is received from the remote monitoring support apparatus 120 that transmitted the diagnosis instruction in step S403 (step S404). In step S404, when the corresponding response information is received (step S404: Yes), the report information is generated based on the received response information (step S405).

In step S405, for example, report information indicating the diagnosis result received in step S404: Yes is generated. In step S405, for example, report information used to create a report may be generated based on a plurality of diagnosis results received in the past, including the diagnosis result received in step S404: Yes.

Thereafter, the report information generated in step S405 is output to the corresponding external device or the like (step S406), and the series of processes is terminated. In step S406, for example, the report information indicating the diagnosis result generated in step S405 is output by being displayed on a display included in a personal computer that implements the operation terminal device 131. In step S 406, for example, print information based on report information used to create a report may be output to the operation terminal device 131 connected to the management server computer 130.

In step S404, if the corresponding response information has not been received (step S404: No), it is determined whether or not a predetermined standby time has elapsed since the diagnosis instruction was transmitted in step S403 (step S407). The standby time used for the determination in step S407 is based on the estimated time required for executing the diagnosis operation in the elevator 101 and receiving the result of the diagnosis operation, for example, the administrator of the remote monitoring system 100, etc. Can be set arbitrarily.

In step S407, if the predetermined standby time has not elapsed since the diagnosis instruction was transmitted in step S403 (step S407: No), the process returns to step S404. On the other hand, in step S407, if a predetermined waiting time has elapsed without receiving the corresponding response information after transmitting the diagnosis instruction in step S403 (step S407: Yes), a worker request process is performed (step S407). S408), a series of processing ends.

In the worker request process in step S408, for example, for the operation terminal device 131 connected to the management server computer 130, the elevator 101 that requires dispatch of a worker to the display of the operation terminal device 131 is provided. For example, a process of outputting information on displaying information on the location of the elevator 101 and information on the location of the elevator 101 is performed.

Next, a processing procedure of the remote monitoring support device 120 constituting the remote monitoring system 100 according to the embodiment of the present invention will be described. FIG. 5 is a flowchart showing a processing procedure of the remote monitoring support apparatus 120 constituting the remote monitoring system 100 according to the embodiment of the present invention.

5, first, it is determined whether or not the diagnosis instruction transmitted from the management server computer 130 in step S403 of FIG. 4 described above has been received (step S501). In step S501, when the corresponding diagnosis instruction has not been received (step S501: No), the process proceeds to step S504.

In step S501, when a corresponding diagnosis instruction is received (step S501: Yes), it is determined whether or not the diagnosis instruction received in step S501: Yes is a diagnosis instruction related to the reservation diagnosis operation (step S502). In step S502, when the diagnosis instruction received in step S501: Yes is not a diagnosis instruction related to the reservation diagnosis operation (step S502: No), the process proceeds to step S505.

In step S502, if the diagnosis instruction received in step S501 is a diagnosis instruction related to the reservation diagnosis operation (step S502: Yes), the remote diagnosis scheduled date and time included in the received diagnosis instruction is extracted, and the extracted remote The scheduled diagnosis date and time are stored (step S503). In step S503, the remote diagnosis scheduled date and time extracted from the diagnosis instruction related to the reservation diagnosis operation is stored in the memory 203 or the like that implements the storage unit 321.

Then, it is determined whether or not the scheduled remote diagnosis date and time stored in step S503 has arrived (step S504). In step S504, when the scheduled remote diagnosis date and time stored in step S503 has not arrived (step S504: No), the process returns to step S501. As a result, even when another diagnostic instruction is received while waiting for a diagnostic operation corresponding to the diagnostic instruction relating to the previously received reservation diagnostic operation, processing according to the other diagnostic instruction can be performed. .

In step S504, when the scheduled remote diagnosis date and time stored in step S503 arrives (step S504: Yes), a diagnostic operation execution instruction is generated (step S505). In step S505, the diagnostic operation execution instruction is generated directly from the diagnostic instruction received in step S501: Yes, or based on the diagnostic instruction related to the scheduled diagnosis operation in which the remote diagnosis scheduled date and time is stored in step S503.

Next, the diagnostic operation execution instruction generated in step S505 is output to the control board 110 of the elevator 101 to be monitored (step S506), and the number of times the diagnostic operation execution instruction is output is incremented by 1 (step S507). At the same time, the elapsed time from the output of the diagnostic operation execution instruction in step S506 is started (step S508). In step S507 and step S508, the number of outputs can be counted and the elapsed time can be counted by using an area in the memory 203 or the like.

Then, as a result of outputting the diagnostic operation execution instruction in step S506, it is determined whether or not signals (uplink signals, downlink signals) input / output to / from the control board 110 have been acquired (step S509). In step S509, when the corresponding signal input / output to / from the control board 110 is acquired (step S509: Yes), response information is generated based on the signal acquired in step S509 (step S510), and the management server computer The response information generated in step S510 is transmitted to 130 (step S511), and the series of processing ends.

On the other hand, if the corresponding signal input / output to / from the control board 110 has not been acquired in step S509 (step S509: No), whether or not the elapsed time starting the timing in step S508 has reached a predetermined time. Is determined (step S512). If it is determined in step S512 that the elapsed time started in step S508 has not reached the predetermined time (step S512: No), the process returns to step S509.

In step S512, when the elapsed time when the time measurement is started in step S508 reaches a predetermined time without acquiring the corresponding signal input / output to / from the control board 110 (step S512: Yes), step S501: It is determined whether or not the number of outputs of the diagnostic operation execution instruction corresponding to the diagnosis instruction received in Yes (the number of outputs counted up in step S507) has reached a specified number (step S513).

In step S513, if the number of times of output of the diagnostic operation execution instruction has not reached the specified number (step S513: No), the diagnostic operation execution instruction is output again (step S514). Then, the number of times of output of the diagnostic operation execution instruction is incremented by +1 (step S515), and the elapsed time from the re-output of the diagnostic operation execution instruction is started in step S514 (step S516), and the process proceeds to step S512. Return.

On the other hand, in step S513, when the number of times of output of the diagnostic operation execution instruction has reached the specified number (step S513: Yes), a predetermined time required for determining whether or not to re-output the diagnostic operation execution instruction (re-output interval) Is changed (step S517), and the diagnostic operation execution instruction is output again (step S518). In step S517, for example, the predetermined time set to “30 minutes” is changed to “3 hours”. Then, the output count of the diagnostic operation execution instruction is incremented by +1 (step S519), and the elapsed time from the re-output of the diagnostic operation execution instruction in step S518 is started (step S520).

Next, as a result of outputting the diagnostic operation execution instruction in step S518, it is determined whether or not signals (uplink signals, downlink signals) input / output to / from the control board 110 have been acquired (step S521). In step S521, when the corresponding signal input / output to / from the control board 110 is acquired (step S521: Yes), the process proceeds to step S510.

On the other hand, if the corresponding signal input / output to / from the control board 110 has not been acquired in step S521 (step S521: No), the elapsed time that started counting in step S520 is the predetermined time changed in step S517. Is determined (step S522). In step S522, when the elapsed time which started time measurement in step S520 has not reached the predetermined time changed in step S517 (step S522: No), the process returns to step S521.

On the other hand, in step S522, when the elapsed time that started timing in step S520 reaches the predetermined time changed in step S517 (step S522: Yes), the number of times that the diagnostic operation execution instruction is output (the output counted up in step S519) It is determined whether or not the number of times has reached the specified number (step S523). The specified number of times serving as a reference in the determination in step S523 may be the same as or different from the specified number of times serving as a reference in the determination in step S513.

In step S523, when the number of outputs of the diagnostic operation execution instruction (the number of outputs counted up in step S519) has not reached the specified number (step S523: No), the process returns to step S518. On the other hand, in step S523, when the number of outputs of the diagnostic operation execution instruction (the number of outputs counted up in step S519) reaches the specified number (step S523: Yes), the service person's dispatch request (information regarding) is output. (Step S524), a series of processing ends. In step S524, a service man's dispatch request (information regarding) is output to the management server computer 130, for example.

Next, a processing procedure of the control board 110 constituting the remote monitoring system 100 according to the embodiment of the present invention will be described. FIG. 6 is a flowchart showing a processing procedure of the control board 110 constituting the remote monitoring system 100 according to the embodiment of the present invention.

In FIG. 6, first, it waits until it receives the input of the diagnostic operation execution instruction output from the remote monitoring support device 120 in step S506 of FIG. 5 described above (step S601: No). In step S601, when an input of a diagnostic operation execution instruction is received (step S601: Yes), a control signal for moving the car 102 to the highest floor with respect to the hoisting machine in the drive mechanism 104 that moves the car 102 up and down. Is output (step S602).

When the hoisting machine in the drive mechanism 104 receives an input of a control signal, the hoist operates according to the received control signal. The drive mechanism 104 (the hoisting machine) outputs an operation signal when operated. Specifically, for example, when the hoisting machine in the drive mechanism 104 is a stepping motor, the number of pulses output from the stepping motor is output as an operation signal.

Next, it is determined whether or not the input of the operation signal output from the drive mechanism 104 (the hoisting machine) is received according to the control signal output in step S602 (step S603). In step S603, when the input of the corresponding operation signal is accepted (step S603: Yes), information (operation state) indicating that the drive mechanism 104 (the hoisting machine in the state) is operating normally is stored. (Step S604), the process proceeds to Step S606.

On the other hand, in step 603, if a control signal for moving the car 102 to the highest floor is output in step S602 and a predetermined time has passed without accepting the input of the corresponding operation signal, the operation signal It is determined that the input has not been accepted (step S603: No), and information (error) indicating that the drive mechanism 104 (the hoisting machine) cannot operate normally is stored (step S605), and step S606. Migrate to

In step S606, a control signal for opening and closing the doors 102c and 105a is output to the motor for opening and closing the doors 102c and 105a (step S606). When the motor that opens and closes the doors 102c and 105a receives an input of a control signal, the motor operates according to the received control signal. The motor that opens and closes the doors 102c and 105a outputs an operation signal when operated. Specifically, for example, when the motor that opens and closes the doors 102c and 105a is a stepping motor, the number of pulses output from the stepping motor is output as an operation signal.

Next, it is determined whether or not an input of an operation signal output from a motor that opens and closes the doors 102c and 105a is received in accordance with the control signal output in step S606 (step S607). In step S607, when an input of a corresponding operation signal is received (step S607: Yes), information (operation state) indicating that the motor that opens and closes the doors 102c and 105a is operating normally is stored ( Step S608) and the process proceeds to Step S610.

On the other hand, in step 607, when a control signal for opening and closing the doors 102c and 105a is output in step S606, if a predetermined time has passed without receiving the corresponding operation signal, input the operation signal. It is determined that it has not been accepted (step S607: No), information (error) indicating that the motor that opens and closes the doors 102c and 105a cannot operate normally is stored (step S609), and the process proceeds to step S610. .

In step S610, it is determined whether or not the floor where the basket 102 is currently located is the lowest floor (step S610). In step S610, for example, if the building where the elevator 101 is installed is a building having a first floor in the basement and a fifth floor on the ground, it is determined whether or not the basket 102 is located on the first floor in the basement. .

In step S610, when the floor in which the car 102 is currently located is not the lowest floor (step S610: No), the control unit 102 moves the car 102 downward by one floor with respect to the hoisting machine in the drive mechanism 104. Is output (step S611). When receiving the input of the control signal, the hoisting machine in the drive mechanism 104 operates according to the received control signal.

Next, it is determined whether or not an input of an operation signal output from the drive mechanism 104 (the hoisting machine) is received according to the control signal output in step S611 (step S612). In step S612, when the input of the corresponding operation signal is received (step S612: Yes), information (operation state) indicating that the drive mechanism 104 (the hoisting machine in the state) is operating normally is stored. (Step S613), the process proceeds to Step S610.

On the other hand, in step 612, if a predetermined time has passed without receiving the input of the corresponding operation signal after outputting the control signal in step S611, it is determined that the input of the corresponding operation signal has not been received. (Step S612: No), information (error) indicating that the drive mechanism 104 (the hoisting machine) cannot operate normally is stored (Step S614), and the process proceeds to Step S610.

On the other hand, in step S610, when the floor where the car 102 is currently located is the lowest floor (step S610: Yes), the control is performed to move the car 102 up and down without stopping with respect to the hoisting machine in the drive mechanism 104. A signal is output (step S615). In step S615, for example, if the building in which the elevator 101 is installed is a building having a first floor in the basement and a fifth floor on the ground, the basket 102 is removed from the first floor to the fifth floor. A control signal for stopping and moving up is output.

Then, it is determined whether or not the input of the operation signal output from the drive mechanism 104 (in the hoisting machine) is received according to the control signal output in step S615 (step S616). In step S616, when the input of the corresponding operation signal is received (step S616: Yes), information (operation state) indicating that the drive mechanism 104 (the hoisting machine in the state) is operating normally is stored. (Step S617), the process proceeds to step S619.

On the other hand, in step 616, if the control signal is output in step S615 and the predetermined time has passed without receiving the input of the corresponding operation signal, it is determined that the input of the operation signal has not been received ( Step S616: No). Then, information (error) indicating that the drive mechanism 104 (the hoisting machine) cannot operate normally is stored (step S618), and the process proceeds to step S619.

In step S619, a control signal for causing the car 102 to move down without stopping is output to the hoisting machine in the drive mechanism 104 (step S619). In step S619, for example, if the building in which the elevator 101 is installed is a building having a first floor in the basement and a fifth floor on the ground, the basket 102 is removed from the fifth floor to the first basement. A control signal for stopping and moving down is output.

Then, it is determined whether or not the input of the operation signal output from the drive mechanism 104 (the hoisting machine) is received according to the control signal output in step S619 (step S620). In step S620, when the input of the corresponding operation signal is received (step S620: Yes), information (operation state) indicating that the drive mechanism 104 (the hoisting machine in the state) is operating normally is stored. (Step S621), the process proceeds to Step S623.

On the other hand, in step 620, if a predetermined time has passed without receiving the input of the corresponding operation signal after outputting the control signal in step S619, it is determined that the input of the operation signal is not received ( In step S620: No), information (error) indicating that the drive mechanism 104 (the hoisting machine) cannot operate normally is stored (step S622), and the process proceeds to step S623.

In step S623, it is determined whether or not there is an error in the diagnostic operation of the elevator 101 according to the diagnostic operation execution instruction received in step S601: Yes (step S623). In step S623, for example, by referring to a predetermined storage area on the control board 110, the presence or absence of the error stored in step S605, step S609, step S614, step S618, or step S622 is determined. Determine if there is an error.

If there is no error in the diagnostic operation in step S623 (step S623: No), the series of processes is terminated. On the other hand, if there is an error in the diagnostic operation in step S623 (step S623: Yes), an alarm signal indicating the corresponding error is generated (step S624). Thereafter, the alarm signal generated in step S624 is output to the remote monitoring support device 120 (step S625), and the series of processing ends.

Thus, according to the remote monitoring system 100 of the embodiment of the present invention, even when the operator forgets the input operation of the diagnostic operation by the reservation diagnostic operation, each elevator 101 can be monitored periodically. it can. Thereby, the safety of the user can be ensured.

In the embodiment described above, the example in which the maintenance / inspection terminal 110a is provided integrally with the control board 110 has been described. However, the maintenance / inspection terminal 110a is provided integrally with the control board 110. Not limited to. The maintenance / inspection terminal 110 a only needs to be electrically connected to the input terminal of the control board 110, and may be separate from the control board 110.

In the above-described embodiment, the remote monitoring support device 120 and the control board 110 are connected via the connector that realizes the maintenance inspection terminal 110a and the connector that realizes the connection terminal 121a. The connection method between the remote monitoring support device 120 and the control board 110 is not limited to this. For example, the remote monitoring support device 120 and the control board 110 may be connected by directly connecting the main control board 121 and the control board 110 by wiring. In addition, for example, remote monitoring support is achieved by directly connecting each part that inputs and outputs signals to and from the control board 110 and the main control board 121 by wiring, such as a board operation panel and a cage operation panel. The device 120 and the control board 110 may be connected.

Further, in the above-described embodiment, the elevator control board is operated according to the all floor stop instruction, and then the operation according to the non-stop ascending movement instruction is performed, and then the non-stop descending movement is performed. Although the diagnostic operation execution instruction for performing the operation according to the instruction is used, the contents of the diagnostic operation execution instruction are not limited to this. The diagnostic operation execution instruction is, for example, a diagnostic operation that performs an operation according to a non-stop ascending movement instruction, performs an operation according to a non-stop descending movement instruction, and then performs an operation according to an all-floor stop instruction. It may be an execution instruction. In this case, either the operation according to the non-stop ascending movement instruction or the operation according to the non-stop descending movement instruction may be performed first.

In the above-described embodiment, an example in which the management server computer 130 outputs a diagnosis instruction as an instruction signal has been described. However, the instruction signal output by the management server computer 130 is not limited to a diagnosis instruction. In addition to the diagnostic instruction, the management server computer 130 uses, for example, an instruction signal (notification information transmission instruction) for instructing transmission of notification information regarding the history of operation stored in the control board 110 as an instruction signal. 120 may be transmitted.

The notification information related to the history of operation in this case includes, for example, the number of activations, the travel distance of the cage 102, the travel time of the cage 102, the number of operations of various relays that are activated during the raising / lowering operation of the cage 102 and the opening / closing operations of the doors 105a and 102c It can be realized by information about such as. In this case, each time the management server computer 130 receives a predetermined input operation in the management server computer 130 or periodically transmits a transmission instruction of notification information related to the history of operation operations.

In the above-described embodiment, the diagnostic operation execution instruction including the all floor stop instruction, the non-stop ascending movement instruction, and the non-stop descending movement instruction is generated. However, the remote monitoring support device according to the diagnosis instruction The execution instruction generated by 120 is not limited to this. For example, when the remote monitoring support device 120 receives a diagnosis instruction transmitted from the management server computer 130 instead of the above-described diagnosis operation execution instruction, the control board 110 that controls the operation of the elevator 101 is individually stopped. An execution instruction, a non-stop ascending movement execution instruction, and a non-stop descending movement execution instruction may be separately generated.

In this case, the generated execution instructions are sequentially output, a signal input / output to / from the control board 110 is acquired according to each output execution instruction, response information based on the acquired signal is generated, and the management server Send to computer. Further, in this case, when a signal corresponding to the execution instruction output before the execution instruction is acquired for each generated execution instruction, an execution instruction that is different from the execution instruction that has already been output is output. Response information may be generated when a signal corresponding to the execution instruction is acquired.

According to the remote monitoring system 100 that performs the diagnostic operation on the control board 110 by such a method, the remote monitoring support device 120 applies the control board 110 to the control board 110 during the diagnostic operation according to the diagnostic instruction transmitted from the management server computer 130. Thus, it is possible to subdivide and output instructions relating to the operation to be executed by the elevator 101 during the diagnosis operation. As a result, the amount of information per communication between the remote monitoring support device 120 and the control board 110 can be suppressed.

In the above-described embodiment, when the diagnosis instruction transmitted from the management server computer 130 and received by the remote monitoring support device 120 is a diagnosis instruction for the reservation diagnosis operation, the diagnosis instruction is issued from the management server computer 130 thereafter. Even in a situation in which the remote diagnosis is not transmitted, the remote monitoring support device 120 is based on the diagnosis instruction already received every time the scheduled date and time of remote diagnosis arrives, based on the previously received diagnosis instruction of the reservation diagnosis operation. Although the remote monitoring system 100 that restarts the interrupted diagnostic operation by generating and outputting the diagnostic operation execution instruction has been described, the method of restarting the diagnostic operation is not limited to this.

For example, instead of the above method, when the diagnostic operation by the control board 110 is interrupted, the management server computer 130 generates a diagnostic instruction again and transmits the diagnostic instruction to the remote monitoring support device 120 to interrupt the diagnostic operation. The diagnosis operation may be resumed.

In this case, when the management server computer 130 receives an input operation of the reservation diagnosis operation, the management server computer 130 stores the scheduled remote diagnosis date and time in the storage unit 311. Then, after transmitting a diagnostic instruction to the remote monitoring support apparatus 120 based on the stored contents in the storage unit 311, when a scheduled remote diagnosis date and time has arrived, a diagnostic instruction is transmitted to the remote monitoring support apparatus 120. . In this case, the diagnosis instruction may be transmitted to the remote monitoring support device 120 when a predetermined time has elapsed since the diagnosis instruction was transmitted, that is, periodically.

Further, in this case, the timing at which the management server computer 130 transmits the diagnosis instruction again to resume the interrupted diagnosis operation is transmitted after the diagnosis instruction corresponding to the input operation of the diagnosis operation is transmitted. After a time longer than a predetermined time, which is a reference for determining whether or not the diagnostic operation is interrupted, is passed. Thereby, in remote monitoring support device 120, it is suppressed that the process according to the diagnostic instruction according to the input operation of the diagnostic operation and the process according to the diagnostic instruction for resuming the diagnostic operation are performed redundantly. And it can suppress that the processing burden of the remote monitoring assistance apparatus 120 increases unnecessarily.

As described above, in the remote monitoring system 100 according to the embodiment of the present invention, the management server computer 130 that communicates with the remote monitoring support device 120 instructs the remote monitoring support device 120 to make a diagnosis at a predetermined timing. When the remote monitoring support apparatus 120 receives the diagnostic instruction transmitted from the management server computer 130, the remote monitoring support apparatus 120 outputs a diagnostic operation execution instruction to the control board 110, and the control board according to the output diagnostic operation execution instruction. Signals input / output to / from 110 are acquired. Then, when the remote monitoring support device 120 outputs a diagnostic operation execution instruction and a predetermined time has elapsed before acquiring a signal input / output to / from the control board 110 according to the diagnostic operation execution instruction, The diagnostic operation is judged to have been interrupted, and after a predetermined waiting time has elapsed from the judgment, the diagnostic operation execution instruction is output again.

According to the remote monitoring system 100 of the embodiment of the present invention, a diagnostic operation by the control board 110 is interrupted because a call (such as a call by a user's operation) that does not originate from the diagnostic operation is entered during the diagnostic operation by remote monitoring. In this case, the diagnostic operation can be resumed by the remote monitoring support device 120 after a predetermined time has elapsed since the interruption. As a result, even when the diagnosis operation by the control board 110 is interrupted, the diagnosis operation can be reliably completed without imposing a burden on the management server computer 130.

Thus, the burden on the management server computer 130 for the diagnostic operation can be reduced, and the remote monitoring of the plurality of elevators 101 by the management server computer 130 can be reliably performed. As a result, the reliability of the elevator 101 can be improved, the safety of the user can be ensured, and the user can use the elevator 101 with peace of mind.

Further, according to the remote monitoring system 100 of the embodiment of the present invention, the number of communications between the remote monitoring support device 120 and the management server computer 130 can be suppressed, and the remote monitoring support device 120 and management server related to the communication can be suppressed. The burden on the computer 130 can be reduced.

In addition, the remote monitoring system 100 according to the embodiment of the present invention is characterized in that when the re-output of the diagnostic operation execution instruction is continuously performed a predetermined number of times, the interval at which the diagnostic operation execution instruction is re-output is changed. .

As described above, when the re-output of the diagnostic operation execution instruction is continuously performed a predetermined number of times, that is, when the state where the signal output from the control board 110 cannot be acquired to some extent continues, the diagnostic operation execution instruction is re-output. By changing the interval, the diagnostic operation can be reliably completed without imposing a burden on the management server computer 130 even when the diagnostic operation by the control board 110 is interrupted.

Specifically, for example, when the situation in which the diagnosis operation of the elevator 101 cannot be performed due to, for example, the transportation of luggage or cleaning work continues to some extent, the diagnosis is performed again after waiting for an estimated time that the situation will change. The operation execution instruction can be output again. As a result, the time zone of the diagnostic operation can be shifted, or the diagnostic operation can be performed again on the next day.

As a result, the number of communications between the remote monitoring support device 120 and the control board 110 performed to re-output the diagnostic operation execution instruction can be suppressed, and a notification indicating an abnormality of the elevator 101 output from the control board 110 can be obtained. The remote monitoring support device 120 can facilitate acquisition.

As a result, the remote monitoring of the elevator 101 can be reliably performed regardless of whether or not the diagnostic operation is performed. Therefore, the reliability of the elevator 101 is improved, the safety of the user is ensured, and the user Can use the elevator 101 with peace of mind.

In addition, the remote monitoring system 100 according to the embodiment of the present invention is characterized in that, when the diagnosis operation execution instruction is re-output for a predetermined number of times, information related to a service person's dispatch request is output. Yes.

According to the remote monitoring system 100 according to the embodiment of the present invention, there is a state where a signal output from the control board 110 cannot be acquired when the re-output of the diagnostic operation execution instruction is continuously performed a predetermined number of times. If it continues, the information about the service person's dispatch request can be output to prompt confirmation by the service person.

As a result, when an abnormality that is difficult to detect by remote monitoring has occurred, it is possible to promptly take action to eliminate the abnormality, thereby improving the reliability of the elevator 101 and improving the safety of the user. And the elevator 101 can be used with peace of mind by the user.
