[0009] Embodiment 1 Fig. 1 is a block diagram showing an escalator maintenance operation device according to embodiment 1. The escalator maintenance operation device according to embodiment 1 includes a first microphone 1, a second microphone 2, a first speaker 3, a second speaker 4, an operating device 5, a driving device 6, and a control device 7A.

[0010] The voice of a worker performing maintenance and inspection is input to the first microphone 1. The voice input to the first microphone 1 is input to the control device 7A.

[0011] The voice of an operator operating the operation device 5 is input to the second microphone 2. The voice input to the second microphone 2 is input to the control device 7A.

[0012] The first speaker 3 emits a voice toward a worker performing maintenance and inspection. The first speaker 3 is disposed adjacent to the first microphone 1. This allows the worker performing maintenance and inspection to input his / her own voice into the first microphone 1 and to hear the voice emitted by the first speaker 3. The first speaker 3 is controlled by the control device 7A.

[0013] The second speaker 4 emits sound toward an operator operating the operation device 5. The second speaker 4 is disposed adjacent to the second microphone 2. This allows the operator operating the operation device 5 to input his or her own voice into the second microphone 2, and also allows the operator to hear the sound emitted by the second speaker 4. The second speaker 4 is controlled by the control device 7A.

[0014] The operating device 5 is held by an operator. The operating device 5 is operated by the operator. When the operating device 5 is operated, an operation signal is output from the operating device 5. The operation signal output from the operating device 5 is input to the control device 7A. The operating device 5 is a device that is operated to move the steps of the escalator during maintenance and inspection.

[0015] The drive device 6 drives the steps of the escalator. The drive device 6 is controlled by a control device 7A. The control device 7A controls the drive device 6, thereby controlling the drive of the steps of the escalator.

[0016] Here, a procedure performed by the worker and the operator during the maintenance and inspection of the escalator will be briefly described. First, in the maintenance and inspection of the escalator, when the escalator is to be driven, the worker emits a voice indicating the operation details of the escalator. After that, the operator listens to the voice emitted by the worker, and emits a voice indicating the same operation details as the operation details indicated by the voice heard by the operator. After that, the operator operates the operation device 5 according to the operation details indicated by the voice heard by the operator. After that, the worker again emits a voice indicating the operation details of the escalator. If the operation details of the operation device 5 operated by the operator and the operation details indicated by the voice again emitted by the worker match, the control device 7A controls the driving of the drive device 6 so that the escalator is driven according to the operation details of the operation device 5 operated by the operator.

[0017] Fig. 2 is a block diagram showing the control device 7A of Fig. 1. The control device 7A has a storage device 71, a determination device 72, and a control device main body 73.

[0018] The voices of the worker and the operator are stored in advance in storage device 71. The voices of the worker and the operator are stored in storage device 71 before maintenance and inspection of the escalator is performed. The voices of a plurality of workers and the voices of a plurality of operators may be stored in storage device 71. In this case, before maintenance and inspection is performed, the voice of the worker in the current maintenance and inspection is identified in advance from the voices of the plurality of workers, and the voice of the operator in the current maintenance and inspection is identified in advance from the voices of the plurality of operators.

[0019] When maintenance and inspection of the escalator is performed, the voice of the worker input to the first microphone 1 is input to the determination device 72. The voice of the worker input to the first microphone 1 includes the operation details of the escalator during the maintenance and inspection. Furthermore, when maintenance and inspection of the escalator is performed, the voice of the operator input to the second microphone 2 is input to the determination device 72. The voice of the operator input to the second microphone 2 includes the operation details of the escalator during the maintenance and inspection.

[0020] In this example, the driving of the escalator refers to the driving of the steps of the escalator. The operation of the escalator during maintenance and inspection can be "up operation", "down operation", "slow up operation", "slow down operation", "short distance up operation", "short distance down operation", etc. "Short distance up operation" is an operation in which the steps arranged on the forward side of the step movement path move toward the upper floor by a preset distance. In this example, the preset movement distance of the steps in "short distance up operation" is about 100 mm. "Short distance down operation" is an operation in which the steps arranged on the forward side of the step movement path move toward the lower floor by a preset distance. In this example, the preset movement distance of the steps in "short distance down operation" is about 100 mm.

[0021] In addition, the operation of the escalator during the maintenance inspection includes "inspection of the safety switch," "inspection of the handrail drive device," and "inspection of the drive unit." "Inspection of the safety switch" refers to operation of the escalator in which an opening of the step formed by removing some of the steps from a plurality of steps arranged in a row is disposed at a position corresponding to the area in which the safety switch is disposed. This allows the worker to perform the maintenance inspection of the safety switch. "Inspection of the handrail drive device" refers to operation of the escalator in which an opening of the step is disposed at a position corresponding to the area in which the handrail drive device is disposed. This allows the worker to perform the maintenance inspection of the handrail drive device. "Inspection of the drive unit" refers to operation of the escalator in which an opening of the step is disposed at a position corresponding to the area in which the drive unit is disposed. This allows the worker to perform the maintenance inspection of the drive unit. In addition, when there are multiple drive units, the operation of the escalator during the maintenance inspection may include "inspection of the first drive unit" and "inspection of the second drive unit."

[0022] When maintenance and inspection of an escalator is performed, the determination device 72 determines whether the voice of the worker input to the first microphone 1 and the voice of the worker stored in the storage device 71 are the voice of the same person. In this example, if the voice of the worker input to the first microphone 1 and the voice of the worker stored in the storage device 71 are the voice of the same person, it is determined that the voices of the workers are the same person.

[0023] Furthermore, when maintenance and inspection of the escalator is performed, the determination device 72 determines whether the operator's voice input to the second microphone 2 and the operator's voice stored in the storage device 71 are the voice of the same person. In this example, if the operator's voice input to the second microphone 2 and the operator's voice stored in the storage device 71 are the voice of the same person, it is determined that the operator's voices are the same person.

[0024] Furthermore, when the determination device 72 determines that the voice of the worker is the same person and the voice of the operator is the same person, the determination device 72 determines whether or not the driving details indicated by the voice input to the first microphone 1 match with the driving details indicated by the voice input to the second microphone 2. In this example, it is determined that the driving details match when the driving details indicated by the voice input to the first microphone 1 match with the driving details indicated by the voice input to the second microphone 2.

[0025] Furthermore, when the determination device 72 determines that the driving details match, the determination device 72 determines whether or not the driving details indicated by the voice input to the first microphone 1 match with the operation details of the operation device 5 operated by the operator. In this example, it is considered that the driving details and the operation details match when the driving details indicated by the voice input to the first microphone 1 match with the operation details of the operation device 5. Note that the determination device 72 may also determine whether or not the driving details indicated by the voice input to the second microphone 2 match with the operation details of the operation device 5.

[0026] Furthermore, when the determination device 72 determines that the driving contents and the operation contents match, the determination device 72 determines whether or not the driving contents indicated by the voice input to the first microphone 1 after the operation of the operation device 5 match the operation contents of the operation device 5 operated by the operator. In this example, a match between the driving contents indicated by the voice input to the first microphone 1 after the operation of the operation device 5 and the operation contents of the operation device 5 is regarded as a match between the post-operation driving contents and the operation contents. Each determination result of the determination device 72 is input to the control device main body 73.

[0027] The control device main body 73 controls the driving of the drive device 6. In addition, the control device main body 73 controls the first speaker 3 to emit sound, and further controls the second speaker 4 to emit sound.

[0028] The operation details of the operation device 5 operated by the operator are input to the control device main body 73. When the determination device 72 determines that the post-operation driving details and the operation details match, the control device main body 73 controls the driving of the escalator steps by the drive device 6 according to the operation details of the operation device 5.

[0029] Fig. 3 is a configuration diagram showing an escalator equipped with the escalator maintenance operation device of Fig. 1. The escalator includes the escalator maintenance operation device, a truss 8, and a plurality of steps 9 provided on the truss 8. In Fig. 3, an opening 91 of the steps 9 is formed in the longitudinal center of the inclined portion of the truss 8.

[0030] The truss 8 is installed across a lower floor 10 and an upper floor 11 of the building. A lower machine room 81 is arranged in a portion of the truss 8 adjacent to the lower floor 10. An upper machine room 82 is arranged in a portion of the truss 8 adjacent to the upper floor 11. The upper machine room 82 accommodates a drive unit 6 and a control unit 7A.

[0031] In this example, worker A performs maintenance and inspection work at the inclined portion of truss 8. A first microphone 1 and a first speaker 3 are arranged at the inclined portion of truss 8. When worker A performs maintenance and inspection work in a lower machine room 81, the first microphone 1 and the first speaker 3 may be arranged in the lower machine room 81. Also, the first microphone 1 and the first speaker 3 may be arranged at each of a plurality of locations on the truss 8.

[0032] In this example, operator B operates the operation device 5 on the upper floor 11. The operation device 5 is connected to the control device 7A via a cable. When operator B operates the operation device 5, operator B connects the operation device 5 to the control device 7A. When the operation of the operation device 5 is completed, operator B disconnects the operation device 5 from the control device 7A.

[0033] Fig. 4 is an enlarged view showing the operation device 5 of Fig. 3. The operation device 5 has an up button 51 and a down button 52. When an up operation is performed during maintenance and inspection work, the operator B operates the up button 51. On the other hand, when a down operation is performed during maintenance and inspection work, the operator B operates the down button 52.

[0034] A second microphone 2 and a second speaker 4 are attached to the operation device 5. The second microphone 2, the second speaker 4 and the operation device 5 constitute a portable operation device 12. The portable operation device 12 is shown in FIG.

[0035] Next, the operation of the escalator maintenance operation device will be described. Fig. 5 is a flow chart showing the operation of the escalator maintenance operation device of Fig. 1. When worker A inputs his / her voice into the first microphone 1 and operator B inputs his / her voice into the second microphone 2, in step S101, the escalator maintenance operation device performs a first determination process. In the first determination process, determination device 72 determines whether the voice of worker A is the same person or not, and determines whether the voice of operator B is the same person or not.

[0036] In step S101, if determination device 72 determines that the voice of worker A is not the same person, or if determination device 72 determines that the voice of operator B is not the same person, the escalator maintenance operation device performs a warning process in step S102. In the warning process, under the control of control device main body 73, first speaker 3 emits a voice instructing that the voice of worker A be input into first microphone 1, and second speaker 4 emits a voice instructing that the voice of operator B be input into second microphone 2.

[0037] In step S101, when the determination device 72 determines that the voice of worker A is the same person and also determines that the voice of operator B is the same person, the escalator maintenance operation device performs a second determination step in step S103. In the second determination step, the determination device 72 determines whether or not the operation contents match.

[0038] If the determination device 72 determines in step S103 that the operation details do not match, the process of the escalator maintenance operation device proceeds to step S102.

[0039] In step S103, when the determination device 72 determines that the operation details match, and further when the operator B operates the operation device 5, the escalator maintenance operation device performs a third determination step in step S104. In the third determination step, the determination device 72 determines whether or not the operation details match the operation details.

[0040] If the determination device 72 determines in step S104 that the operation details do not match the operation details, the process of the escalator maintenance operation device proceeds to step S102.

[0041] In step S104, when determination device 72 determines that the driving content and the operation content match, and the voice of worker A is input to first microphone 1 after operating operation device 5, the escalator maintenance operation device performs a fourth determination step in step S105. In the fourth determination step, determination device 72 determines whether or not the post-operation driving content and the operation content match.

[0042] If the determination device 72 determines in step S105 that the post-operation operation content does not match the operation content of the operation device 5, the process of the escalator maintenance operation device proceeds to step S102.

[0043] If in step S105, determination device 72 determines that the post-operation operation contents match the operation contents, then in step S106, the escalator maintenance operation device performs the operation process. In the operation process, drive device 6 drives escalator steps 9 in accordance with the operation contents of operation device 5. This allows worker A to perform maintenance inspection. With this, the operation of the escalator maintenance operation device is completed.

[0044] As described above, the escalator maintenance operation device according to the first embodiment includes the first microphone 1, the second microphone 2, the determination device 72, and the drive device 6. The voice of the worker A performing the maintenance and inspection is input to the first microphone 1. The voice of the operator B operating the operation device 5 is input to the second microphone 2. The determination device 72 determines whether or not the operation contents match. When the determination device 72 determines that the operation contents match, the drive device 6 drives the steps 9 of the escalator according to the operation contents of the operation device 5. With this configuration, the worker A does not need to operate the operation device 5. This makes it possible to reduce the workload of the worker A.

[0045] In addition, the determination device 72 further determines whether or not the driving details and the operation details match. When the determination device 72 determines that the driving details match and that the driving details and the operation details match, the drive device 6 drives the escalator according to the operation details of the operation device 5. With this configuration, it is possible to prevent the operator B from making an operation error.

[0046] In addition, the determination device 72 further determines whether or not the post-operation driving content and the operation content match. When the determination device 72 determines that the driving content and the operation content match, and that the post-operation driving content and the operation content match, the drive device 6 drives the escalator according to the operation content of the operation device 5. With this configuration, it is possible to prevent the escalator from being driven due to a mistake in speech by the worker A.

[0047] Furthermore, the determination device 72 determines whether the voice of worker A is the same person, and whether the voice of operator B is the same person. If the determination device 72 determines that the voice of worker A is the same person and that the voice of operator B is the same person, the drive device 6 drives the escalator in accordance with the operation content of the operation device 5. According to this configuration, when there are multiple workers A and multiple operators B at a maintenance and inspection work site, the escalator is driven only if the voice of worker A is the same person and the voice of operator B is the same person. This makes it possible to prevent the escalator from being driven by the voice of another worker A.

[0048] In the first embodiment, the determination device 72 determines whether the voice of the worker A is the same person, and determines whether the voice of the operator B is the same person. However, the determination device 72 may not determine whether the voice of the worker A is the same person and whether the voice of the operator B is the same person.

[0049] Embodiment 2 FIG. 6 is a block diagram showing an escalator maintenance operation device according to the second embodiment. FIG. 7 is a block diagram showing the control device of FIG. 6. FIG. 8 is a configuration diagram showing an escalator equipped with the escalator maintenance operation device of FIG. 6. The escalator maintenance operation device according to the second embodiment includes a drive device 6, a control device 7B, a microphone 13, and a speaker 14. The drive device 6 is similar to the drive device 6 of the first embodiment. The microphone 13 and the speaker 14 are disposed on the inclined portion of the truss 8. When the worker A performs maintenance and inspection work in the lower machine room 81, the microphone 13 and the speaker 14 may be disposed in the lower machine room 81. The microphone 13 and the speaker 14 may be disposed at each of a plurality of locations on the truss 8.

[0050] The control device 7B includes a storage device 71, a determination device 72, and a control device main body 73.

[0051] The storage device 71 stores in advance the voice of the operator A, as in the first embodiment. However, unlike the first embodiment, the storage device 71 does not store the voice of the operator B.

[0052] Determination device 72 determines whether the voice of the worker is that of the same person when maintenance and inspection of the escalator is performed, similarly to embodiment 1. Unlike embodiment 1, determination device 72 does not determine whether the voice of operator B is that of the same person, does not determine whether the driving contents match, does not determine whether the driving contents and the operation contents match, and does not determine whether the post-operation driving contents and the operation contents match.

[0053] Unlike the first embodiment, the operation details of the operating device 5 are not input to the control device main body 73. When maintenance and inspection of the escalator is performed, the operation details indicated by the voice input to the microphone 13 are input to the control device main body 73. When the determination device 72 determines that the voice of the worker is the same person, the control device main body 73 controls the driving of the escalator steps 9 by the drive device 6 according to the operation details indicated by the voice input to the microphone 13. The control device main body 73 controls the speaker 14 to emit voice. The other configurations are the same as those of the first embodiment.

[0054] Next, the operation of the escalator maintenance operation device will be described. Fig. 9 is a flow chart showing the operation of the escalator maintenance operation device of Fig. 6. When worker A inputs the voice of worker A into microphone 13, in step S201, the escalator maintenance operation device performs a determination process. In the determination process, determination device 72 determines whether the voice of worker A is the same person or not.

[0055] If in step S201, determination device 72 determines that the voice of worker A is not that of the same person, the escalator maintenance operation device performs a warning process in step S202. In the warning process, under the control of control device main body 73, speaker 14 emits a voice instructing to input the voice of worker A into microphone 13.

[0056] On the other hand, if in step S201, determination device 72 determines that the voice of worker A is that of the same person, then in step S203, the escalator maintenance operation device performs the operation process. In the operation process, drive device 6 drives escalator steps 9 in accordance with the operation content indicated by the voice input to microphone 13. This allows worker A to perform maintenance inspection. With this, the operation of the escalator maintenance operation device is completed.

[0057] As described above, the escalator maintenance operation device according to the second embodiment includes the microphone 13, the storage device 71, the determination device 72, and the drive device 6. The voice of the worker A who performs the maintenance inspection is input to the microphone 13. The voice of the worker A who performs the maintenance inspection is stored in the storage device 71. The determination device 72 determines whether or not the voice input to the microphone 13 matches the voice of the worker A stored in the storage device 71. When the determination device 72 determines that the voice input to the microphone 13 matches the voice of the worker A stored in the storage device 71, the drive device 6 drives the steps 9 of the escalator according to the operation content indicated by the voice input to the microphone 13. According to this configuration, the worker A does not need to operate the operating device 5. This can reduce the workload of the worker A. In addition, the operator B does not need to operate the operating device 5. This can reduce the workload of the operator B.

[0058] In the second embodiment, the configuration has been described in which the driving device 6 drives the steps 9 of the escalator based only on the determination of whether the voice of the worker A is the same person or not. However, a configuration may be adopted in which a voice indicating the operation details is emitted from the speaker 14 after it is determined that the voice of the worker A is the same person. In this case, the determination device 72 determines whether the operation details indicated by the voice input to the microphone 13 before the voice indicating the operation details is emitted from the speaker 14 matches the operation details indicated by the voice input to the microphone 13 before the voice indicating the operation details is emitted from the speaker 14. Based on the determination result of the determination device 72, the driving device 6 drives the steps 9 of the escalator.

[0059] In addition, in each embodiment, an escalator maintenance operation device has been described as an example of an elevator maintenance operation device. However, an elevator maintenance operation device may be an elevator maintenance operation device. In this case, the first microphone 1 or microphone 13 is provided, for example, in a pit, and the second microphone 2 is provided in or on the car. [Explanation of symbols]
