The communication unit 231 receives a signal indicating the sound of the hook having the safety cord hooked thereon as an operation signal from the microphone 11 and the microphone provided in the smartphone 20.
The maintenance person 14 checks the equipment installed in the car 8 on the car 8. At the time of this spot check, the maintenance worker 14 performs operations such as palpation, adjustment, cleaning, and finger confirmation after the spot check. The acceleration sensor provided in the wearable terminal 21 detects the acceleration of the arm caused by the movement of the maintenance person 14. The communication unit 231 receives a signal indicating the acceleration of the arm due to the movement of the maintenance person 14 as a work signal from an acceleration sensor provided in the wearable terminal 21.
The maintenance person 14 moves the position of the car 8 to the interlock checkup position of the car door 9. The encoder 6 detects the position of the car 8.

The estimation unit 233 extracts the amplitude, the period, the duration, and the like of the vibration detected by the acceleration sensor as characteristic data representing the vibration. The estimating unit 233 determines whether or not the characteristic data of the vibration detected by the acceleration sensor 12 falls within a predetermined range with respect to the operation of climbing onto the car 8. The estimating unit 233 determines whether or not the characteristic data of the vibration detected by the acceleration sensor provided in the smartphone 20 falls within a predetermined range with respect to the operation of climbing onto the car 8. The estimation unit 233 determines whether or not the characteristic data of the vibration detected by the acceleration sensor 12 matches the characteristic data of the vibration detected by the acceleration sensor provided in the smartphone 20.

When the feature data of the sound detected by the microphone 11 is within a predetermined range with respect to the opening and closing of the landing door 4, the estimation unit 233 determines that the operation of the interlock point detection of the landing door 4 on the floor where the car 8 is located at this time is in progress.
The estimation unit 233 determines whether or not the landing door 4 is in an open state based on a signal from the landing door switch. The estimating unit 233 determines whether the position of the serviceman 14 is N layers or not based on a signal from an indoor position detecting device provided in the smartphone 20. When both of the determination results are yes, the estimation unit 233 estimates that the maintenance person 14 has performed the operation of manually opening the N-story landing doors 4.
Next, an example of the procedure data stored in the 2 nd storage unit 232 will be described with reference to fig. 3.
Fig. 3 is a diagram showing an example of procedure data stored in the 2 nd storage unit according to the present embodiment.
The step data associates 0 or more preceding actions with each action.
Action a has no corresponding look-ahead action. That is, the operation a is an operation that can be performed first in the maintenance work.
Regarding the action B, the action a corresponds to the preceding action. That is, the operation B is an operation performed after the operation a is performed.
Regarding the action C, as the preceding action, the action a or the action B corresponds thereto. That is, the operation C is performed after any of the operations a and B is performed.
Regarding the operation D, the operation B corresponds to the preceding operation. That is, the operation D is an operation performed after the operation B is performed.
As for the action E, as the preceding action, actions C and D correspond thereto. That is, the operation E is an operation performed after both the operations C and D are performed.
More specifically, for example, regarding the operation of manually opening the landing door 4, the operation of switching the operation mode of the elevator to the manual mode is associated with the preceding operation. For example, the operation of climbing up the car 8 corresponds to the operation of switching the operation mode of the elevator to the manual mode as the preceding operation. For example, the operation of hanging the safety rope corresponds to each operation of performing spot inspection of the equipment on the car 8 as a preceding operation. For example, regarding the operation from above the car 8 to below, the operation of performing spot inspection on the equipment above the car 8 corresponds to the preceding operation. For example, the first operation of the maintenance spot inspection performed in the N-layer corresponds to the last operation of the maintenance spot inspection performed in the N-1 layer as a preceding operation.
Next, an example of data indicating the operation of the maintenance operation stored in the 1 st storage unit 234 will be described with reference to fig. 4.
Fig. 4 is a diagram showing an example of data indicating an operation of the maintenance work stored in the 1 st storage unit according to the present embodiment.
In this example, the estimation unit 233 estimates the operation of the maintenance work performed by the maintenance worker 14 in the order of the operation a, the operation C, the operation B, and the operation E. The 1 st storage unit 234 stores the operations in the order estimated by the estimation unit 233.
The determination unit 235 determines the correspondence between the estimated sequence of operations and the operations indicated by the step data, for example, as follows.
First, the determination unit 235 receives data indicating the operation a. Action a has no corresponding look-ahead action. The determination unit 235 determines that the order of the operation a matches the order of the operations indicated by the step data.
Next, the determination unit 235 receives data indicating the operation C. Regarding action C, the corresponding preceding action is action a or action B. Since it is estimated that the operation a is performed first, the determination unit 235 determines that the order of the operation C matches the order of the operations indicated by the step data.
Next, the determination unit 235 receives data indicating the operation B. The corresponding preceding action of action B is action a. Since it is estimated that the operation a has been performed earlier, the determination unit 235 determines that the order of the operation B matches the order of the operations indicated by the step data.
Next, the determination unit 235 receives data indicating the operation E. The corresponding prior actions of action E are action C and action D. Since it is not estimated that the operation D has been performed first, the determination unit 235 determines that the order of the operation E does not match the order of the operations indicated by the step data.
The determination unit 235 transmits data indicating the determination result to the communication unit 231. The communication unit 231 transmits the data to the notification device 27.
When the notification device 27 is the speaker 10, the speaker 10 notifies the maintenance person 14 of "operation D was not performed before operation E" by, for example, a manual voice. ".
More specifically, for example, when the maintenance worker 14 performs an operation of manually opening the landing door 4 before the operation of switching the operation mode to the manual mode, the speaker 10 notifies the maintenance worker 14 that "the operation mode is not the manual mode". For example, when the maintenance worker 14 performs an operation of climbing up the car 8 before the operation of switching the operation mode to the manual mode, the speaker 10 notifies the maintenance worker 14 that the operation mode is not the manual mode. For example, when any of the operations of performing the spot inspection of the equipment on the car 8 is performed by the maintenance person 14 before the operation of hanging the safety rope, the speaker 10 notifies the maintenance person 14 that "the safety rope is not hung". For example, when the maintenance worker 14 performs an operation of getting off the car 8 before an operation of checking the device X on the car 8, the speaker 10 notifies the maintenance worker 14 of "whether or not the equipment X was forgotten to be checked? ". For example, when the maintenance person 14 performs the first operation of the spot inspection performed on the N-level before the last operation of the spot inspection performed on the N-1 level, the speaker 10 notifies the maintenance person 14 of "whether or not the N-1 level was forgotten to perform the spot inspection? ".
Next, the operation of the elevator maintenance work assisting device 22 will be described with reference to fig. 5.
Fig. 5 is a flowchart showing an example of the operation of the elevator maintenance work support device according to the present embodiment.
In step S1, the communication unit 231 receives the step data from the monitoring center 25. Then, the communication unit 231 transmits the received step data to the 2 nd storage unit 232. Then, the 2 nd storage unit 232 stores the received step data. Then, the operation of the elevator maintenance work support device 23 proceeds to step S2.
In step S2, the communication unit 231 receives a work signal from the work monitoring device 26. Then, the communication unit 231 transmits the received job signal to the estimation unit 233. Then, the operation of the elevator maintenance work support device 23 proceeds to step S3.
In step S3, the estimation unit 233 estimates the operation of the maintenance work performed by the maintenance person 14 based on the received work signal. Then, the estimating unit 233 transmits data indicating the estimated operation to the 1 st storage unit 234 and the determining unit 235. Then, the operation of the elevator maintenance work support device 23 proceeds to step S4.
In step S4, the 1 st storage unit 234 stores data indicating the operation received from the estimation unit 233. Then, the operation of the elevator maintenance work support device 23 proceeds to step S5.
In step S5, the determination unit 235 refers to the step data stored in the 2 nd storage unit 232, and determines whether or not the order of the operations estimated by the estimation unit 233 matches the order of the operations indicated by the step data. If the determination result is "no," the operation of the elevator maintenance work assisting device 23 proceeds to step S6. If the determination result is yes, the operation of the elevator maintenance work assisting device 23 proceeds to step S7.
In step S6, the determination unit 235 transmits data indicating the determination result to the communication unit 231. Then, the communication unit 231 transmits data indicating the determination result to the notification device 27. Then, the operation of the elevator maintenance work support device 23 proceeds to step S7.
In step S7, the elevator maintenance work assisting device 23 determines whether or not the maintenance work is finished. If the determination result is "no," the operation of the elevator maintenance work assisting device 23 proceeds to step S2. If the determination result is yes, the operation of the elevator maintenance work assisting device 23 proceeds to step S8.
In step S8, the communication unit 231 transmits the data indicating the operation stored in the 1 st storage unit 234 to the monitoring center 25. Then, the operation of the elevator maintenance work assisting device 23 is ended.
As described above, the elevator maintenance work support device 23 of the present embodiment includes the estimating unit 233 and the 1 st storage unit 234. The estimation unit 233 estimates the operation of the maintenance work performed by the maintenance worker 14 based on the work signal indicating the maintenance work state of the elevator transmitted from each of the one or more work monitoring devices 26. The 1 st storage unit 234 stores data indicating the operation estimated by the estimation unit 233. That is, the estimating unit 233 specifically estimates the operation of the maintenance work currently performed by the maintenance worker 14 in parallel with the maintenance work of the maintenance worker 14. Thus, even when the maintenance work is performed at random according to the situation, the elevator maintenance work assisting device can create the execution record of the operation of the maintenance work.
The elevator maintenance work support device 23 creates an execution record based on the operation estimated in parallel with the maintenance work by the maintenance worker 14. Thus, the elevator maintenance work support device 23 can prevent the omission of the recording by the maintenance person 14 and the error of the recording by the judgment error. For example, in the building 1 having a large number of floors, the elevator maintenance work assisting device 23 can prevent the floor to be subjected to the maintenance work from being omitted when the maintenance work is performed over the course of the day. The elevator maintenance work support device 23 can leave the judgment of the random strain corresponding to the situation of the site as an implementation record. The performance records the efficiency improvement of the work steps that can be used for the maintenance work and the training of the maintenance work.
The estimation unit 233 combines estimates based on the respective job signals transmitted from each of the plurality of job monitoring devices 26. Thus, the estimation unit 233 can also improve the accuracy of estimation by a simple estimation method in which the estimation speed is prioritized. The estimation unit 233 independently performs estimation based on each of the plurality of job signals in parallel. Thus, the estimation unit 233 can increase the estimation speed. The estimation unit 233 performs the estimation of the operation of the maintenance work at high speed and with high accuracy. Therefore, the estimation unit 233 can perform estimation in parallel with the maintenance work of the maintenance worker 14.
The maintenance worker 14 who performs the maintenance work can communicate with the elevator maintenance work support device 23 via the smartphone 20, for example. The maintenance worker 14 can confirm the operation performed at the site of the maintenance work. The maintenance worker 14 can quickly respond to a case where the operation omission of the maintenance work or the like is found on site.
The elevator maintenance work support device 23 further includes a 2 nd storage unit 232, a determination unit 235, and a communication unit 231. The 2 nd storage unit 232 stores step data indicating the sequence of operations of the maintenance work. The determination unit 235 determines whether or not the order of the operations estimated by the estimation unit 233 matches the order of the operations indicated by the step data stored in the 2 nd storage unit 232. When the determination unit 235 determines that the order of the operation indicated by the step data does not match, the communication unit 231 transmits a signal indicating the determination result of the determination unit 235 to the notification device 27. The notification device 27 notifies the maintenance person 14 of the content indicated by the received signal. Thus, when there is an operation omission or unsafe operation in the maintenance work, the maintenance person 14 notifies the contents of the operation omission or unsafe operation on site. Therefore, the maintenance worker 14 can improve the quality and safety of the maintenance work.
Further, the estimation section 233 uses a signal representing a voice as a job signal. In the case where the work monitoring apparatus 26 is a microphone, the microphone can detect sounds generated from a plurality of devices in a non-contact manner. Thus, the elevator maintenance work support system 22 can reduce the number of work monitoring devices 26.
The estimation unit 233 uses, as the operation signal, a maintenance worker signal indicating the state of the maintenance worker 14 transmitted from the operation monitoring device 26 included in the portable terminal held by the maintenance worker 14. Since the state of the maintenance worker 14 who performs the operation of the maintenance work can be directly collected, the estimation accuracy is improved.
The estimating unit 233 uses a device signal indicating the state of the elevator, which is transmitted from the operation monitoring device 26 provided in the elevator, as the operation signal. Since the state of the elevator to be subjected to the maintenance work can be directly collected, the estimation accuracy is improved.
The estimation unit 233 uses both the maintenance person signal and the equipment signal as the operation signal. Since the elevator operates in accordance with the operation performed by the serviceman 14 and the serviceman 14 operates in response to the operation of the elevator, the serviceman signal and the device signal have a causal relationship with each other. The estimation unit 233 can further improve the accuracy of estimation by using signals having causal relationship with each other in combination.

The notification device 27 notifies the content indicated by the received signal, for example, by character display.
The notification device 27 may be a lamp provided in the elevator. The lamp informs about the content represented by the received signal, for example by means of a blinking pattern.
The portable terminal may be held by a plurality of maintenance persons 14. The operation monitoring device 26 provided in the portable terminal may transmit a signal for identifying the portable terminal to the communication unit 231 together with the operation signal. The elevator maintenance work support device 23 can create an execution record including information of the operating serviceman 14. The maintenance worker 14 can check the operation performed by another maintenance worker 14 who performs the work at the same time on site. Since the maintenance staff 14 can grasp the progress of each work, the work can be efficiently performed in cooperation.
The step data may be data sequentially indicating the order of operations of the maintenance job.
The estimation unit 233 may estimate the operation of the maintenance work performed by the maintenance worker 14 by a machine learning method that is learned in advance using the work signal as an input. The machine learning method may also use an artificial neural network, a bayesian network, a random forest, a support vector machine, deep learning, or the like.
