***Description of action***

Next, an operation example of the determination device 30 according to the present embodiment will be described using the flowchart in FIG. 5 . Hereinafter, an example in which there is only one operator will be described. An example with two or more workers will be described separately.

First, the car position detection unit 3301 detects the position of the car of the elevator based on the car position information received from the elevator control panel 10 (step S10). Then, the car position detection unit 3301 notifies the job estimation unit 3304 of the position of the car.

Next, the operator operation signal detection unit 3302 detects the operator's operation based on the operator operation information received from the elevator control panel 10 (step S20). And the operator's operation signal detection part 3302 notifies the operation of an operator to the job estimation part 3304.

Next, the operator position detection part 3303 detects the position of an operator based on the operator position information received from the operator position acquisition device 21 (step S30). And the operator position detection part 3303 notifies the operation|work estimation part 3304 of the position of an operator.

Next, the work estimation part 3304 estimates the start work of an operator (step S40). Specifically, the job estimation unit 3304 includes the position of the car notified from the car position detection unit 3301 , the operator's operation notified from the operator operation signal detection unit 3302 , and the operator's position notified from the operator position detection unit 3303 . Based on the location, the worker's initiation task is estimated. Specifically, the job estimating unit 3304 relates to the position of the car at the time of the job, the operation of the operator, and the position of the operator in all jobs registered in advance in the memory 34 or the auxiliary storage device 40 . See setting information. The job estimation unit 3304 estimates the job by searching for the job corresponding to the setting information from the notified car position, the operator's operation, and the operator's position.

In addition, when the operation of the operator indicating that the operation has been completed is detected, the operation estimating unit 3304 estimates the end of the operation.

Moreover, the work estimation part 3304 specifies the number of workers from the worker position. As described above, it is assumed here that the number of workers is one.

And the work estimating part 3304 notifies the extraction part 3306 of the estimation result of an initiation work, and the number of workers. In addition, the job estimation unit 3304 notifies the implementation probability update unit 3305 of the estimation result of the starting job.

In addition, in this embodiment, based on the position of a car, an operator's operation, and an operator's position, the work estimating part 3304 estimates the starting work. However, for example, when an operator notifies the determination apparatus 30 of a start work using a terminal device, step S10 - step S40 can be abbreviate|omitted.

Next, the extraction unit 3306 extracts an extraction candidate job (step S50).

Specifically, the extraction unit 3306 reads implementation probability information T10 from the information management unit 341 . Then, the extraction unit 3306 extracts the candidate job based on the implementation probability information T10. In more detail, the extraction unit 3306 extracts, as a candidate job, a job whose probability of being executed next to the starting job notified from the job estimation section 3304 exceeds 0.

In addition, the extraction unit 3306 reads the dangerous event list T21 from the dangerous event storage unit 342 . Then, the extraction unit 3306 extracts a candidate job included in the dangerous event list T21 among the extracted candidate jobs as an extraction candidate job.

And the extraction part 3306 notifies the start-up work of an operator, the number of workers, and an extraction candidate operation|work to the notification determination part 3307.

Next, the notification determination unit 3307 determines whether or not the start work causes a dangerous event (step S60).

Specifically, the notification decision unit 3307 reads the dangerous event list T21 from the dangerous event storage unit 342 . Then, the notification determination unit 3307, it is confirmed whether the start work of the operator is included in the dangerous event list T21. When the start work is included in the dangerous event list T21, the notification determination unit 3307 determines that the start work causes a dangerous event.

When it is determined that the start work causes a dangerous event, the process proceeds to step S80. On the other hand, when it is determined that the start work does not generate a dangerous event, the process proceeds to step S70.

When it is determined in step S60 that the start work does not cause a dangerous event, the notification determination unit 3307 determines whether the execution probability is higher than a threshold value (step S70).

Specifically, the notification determination unit 3307 reads implementation probability information T10 from the information management unit 341 . And the notification determination part 3307 extracts the implementation probability corresponding to the combination of the initiation task and the extraction candidate task from the implementation probability information T10. Further, the notification determination unit 3307 compares the extracted implementation probability with a set threshold value.

If the implementation probability is higher than the set threshold, the process proceeds to step S80. On the other hand, when the implementation probability is equal to or less than the set threshold, the process proceeds to step S90.

In the case of YES in step S60 or YES in step S70, the notification determination unit 3307 determines to notify the possibility of occurrence of a dangerous event (step S80).

Then, the notification determination unit 3307 outputs a notification determination signal to the notification unit 3308 . The notification unit 3308 transmits a notification command to the notification device 50 according to the notification decision signal from the notification decision unit 3307 .

When NO in step S70 or when step S80 is performed, the execution probability update unit 3305 detects the end of the job based on the estimation result received from the job estimation unit 3304 (step S90).

When the job is finished, the process proceeds to step S100. On the other hand, if the job is not finished, the process proceeds to step S10.

When it is detected in step S90 that the job has been completed, the execution probability update unit 3305 determines whether or not the job performed by the operator satisfies a prescribed criterion (step S100).

Specifically, the implementation probability update unit 3305 determines whether or not the work performed by the operator is suitable for use as learning data. As a specific example, the implementation probability update unit 3305 determines step S100 according to whether the total working time is longer than the set time or the like.

If it is determined that the job satisfies the stipulated criteria, the process proceeds to step S110. On the other hand, if it is not determined that the job satisfies the stipulated criteria, the process ends.

If it is determined in step S100 that the job satisfies the prescribed criteria, the execution probability update unit 3305 updates the operator's execution probability information T10 (step S110).

As a specific example, the implementation probability update unit 3305 sets the task transition as a Markov chain model or a Bayesian network. In addition, as a specific example, the implementation probability update unit 3305 receives, as an input, a transition process of a time series operation in an elevator operation, performs maximum likelihood estimation of a transition matrix component, and each operation The implementation probability information is updated by outputting the transition probability between the two.

Next, an operation example of the determination device 30 in the case of two or more workers will be described.

When it is determined that there are two or more workers as a result of step S10 - step S40 being implemented, in step S50, the extraction part 3306 extracts an extraction combination. More specifically, the extraction unit 3306 extracts a candidate job for each worker. And the extraction part 3306 combines the candidate jobs of each extracted worker, and obtains two or more combinations of candidate jobs. In addition, the extraction unit 3306 extracts, as an extraction combination, a combination registered in the dangerous event list T21 according to the number of workers among combinations of a plurality of candidate jobs.

Moreover, the extraction part 3306 notifies the notification determination part 3307 of the start-up work of each worker, the number of workers, and an extraction combination.

Next, in step S60, the notification determination part 3307 confirms whether the combination of the start work of each worker is contained in the dangerous event list T21 according to the number of workers.

When the combination of start work is included in the dangerous event list T21, the process proceeds to step S80. On the other hand, when the combination of start work is not included in the dangerous event list T21, the process advances to step S70.

In step S70, the notification determination part 3307 accumulates the probability that the extraction candidate operation|work of each operator included in an extraction combination is implemented. The integrated value is the probability that the candidate work of each operator is performed in parallel. Then, the notification determining unit 3307 compares the integrated value with the set threshold value.

If the integrated value is higher than the set threshold, the process proceeds to step S80. When the integrated value is equal to or less than the set threshold, the process proceeds to step S90.

Steps S80 to S110 are the same as described above, and thus description thereof is omitted.

***Description of the effect of the embodiment ***

As mentioned above, in this embodiment, the possibility that a dangerous event generate|occur|produces is predicted based on the implementation probability of the candidate work to be implemented next from the worker's current start work. And, when a risk event is highly likely to occur, the notification device is operated. For this reason, according to this embodiment, an operator can take preventive safety measures with respect to the danger which may be caused in the future. Therefore, the operator can take evasive actions in advance for future dangers.

Moreover, in this embodiment, it is also determined whether the present start work itself may generate|occur|produce a dangerous event. And in this embodiment, when the possibility that a start work will generate|occur|produce a dangerous event is high, a notification apparatus is operated. For this reason, according to this embodiment, even if the prediction based on the extraction candidate operation|work performed previously is wrong, it is possible for an operator to take countermeasures for ensuring safety at the stage of a start-up operation.

Embodiment 2.

In the present embodiment, when the notification determining unit 3307 determines to notify the possibility of the occurrence of a dangerous event, an example in which the control signal invalidation unit invalidates the operator operation signal will be described.

7 is a flowchart showing an operation example of the determination device 30 according to the embodiment. In addition, the same reference|symbol is attached|subjected to the operation|movement similar to Embodiment 1, and the description is abbreviate|omitted.

The control signal invalidation unit 3309 transmits a signal for invalidating the operator operation signal to the elevator control panel 10 when the notification determination unit 3307 determines to notify the possibility of the occurrence of the dangerous event (step S120 ).

As a result, the elevator control panel 10 invalidates the operator operation signal.

In addition, an operator operation signal is a control signal input to a control panel by an operator when an operator performs operation of moving an elevator up and down, operation of opening/closing a door, etc.

In addition, invalidation means canceling an operator's operation signal and making an operator's operation invalid.

As described above, when the possibility of occurrence of a dangerous event is predicted by performing the start work or the extraction candidate work, the safety of the work is improved by invalidating the operator operation signal and not performing the start work or the extraction candidate work. can be further raised.

In the present embodiment, the determination device 30 is newly provided with the operator gaze direction detection unit 3310 , and the sensor 20 is connected to the operator gaze direction acquisition device 22 .

The operator's gaze direction acquisition device 22 acquires the operator's gaze direction.

In addition, the same number is attached|subjected to the structural part same as Embodiment 2, and the description is abbreviate|omitted.

9 is an example of a dangerous event list according to the embodiment.

The dangerous event storage unit 342 stores the dangerous event list T22 shown in FIG. 9 .

In the dangerous event list T22, the combination of the dangerous event and the gaze direction of the operator and the operation is shown. That is, when the operator's gaze direction is not in the specific direction described in the dangerous event list T22 and the operation described in the dangerous event list T22 is performed, the dangerous event described in the dangerous event list T22 may occur. The specific direction mentioned above is a weight direction, a car downward direction, a hoistway top direction, etc. as a specific example. In addition, the work shown in FIG. 9 is any one of a start work and a candidate work.

The dangerous event list T22 of FIG. 9A indicates that if the operator 1 performs the operation: #101 without looking at the top of the hoistway, the dangerous event: 101 may occur.

In the dangerous event list T22 of FIG. 9(b), when operator 1 performs operation: #111, and in parallel, operator 2 performs operation: #112 without looking at the weight, there is a possibility that a dangerous event: 111 occurs indicates

10 is a flowchart showing an operation example of the determination device 30 according to the embodiment. In addition, the same reference|symbol is attached|subjected to the operation|movement similar to Embodiment 2, and the description is abbreviate|omitted.

After step S30 is completed, the operator's gaze direction detection unit 3310 detects the operator's gaze direction based on the gaze direction information (step S130). The gaze direction information of the operator acquired by the operator gaze direction acquisition device 22 appears in the gaze direction information.

Then, the operator's gaze direction detection unit 3310 notifies the extraction unit 3306 of the operator's gaze direction.

After step S40 is completed, the extraction unit 3306 extracts an extraction candidate job using the dangerous event list T22 (step S500).

First, the extraction unit 3306 reads the dangerous event list T22 from the dangerous event storage unit 342 . Then, the extraction unit 3306 determines whether the gaze direction of the operator matches the gaze direction shown in the dangerous event list T22. When the gaze direction of the operator coincides with the gaze direction shown in the dangerous event list T22, the extraction unit 3306 extracts a candidate job as in the first embodiment. Further, the extraction unit 3306 extracts, among the extracted candidate jobs, a candidate job matching the job shown in the dangerous event list T22 as an extraction candidate job.

In the case where the dangerous event list T22 shown in Fig. 9A is used, when the operator is not looking at the top of the hoistway, the job: #101 is extracted as the extraction candidate job.

Moreover, when there are two or more workers, the extraction part 306 extracts as an extraction combination the combination of the candidate jobs of the operator which matches the conditions of the dangerous event list T22 shown to FIG.9(b). Specifically, when one operator does not look at the weight, the candidate operation of the operator who does not see the weight corresponds to operation: #112, and the candidate operation of the other operator is operation: #111, the extraction unit In step 306, operation: #112 and operation: #111 are extracted as extraction combinations.

Then, the extraction unit 3306 notifies the notification determination unit 3307 of the extraction candidate job or extraction combination.

Next, the notification determination unit 3307 determines whether the initiation work causes a dangerous event using the dangerous event list T22 (step S600).

First, the notification determination unit 3307 reads the dangerous event list T22 from the dangerous event storage unit 342 . In addition, the notification determining unit 3307 checks whether the combination of the operator's gaze direction and the estimated starting work matches the gaze direction shown in the dangerous event list T22 and the condition of the starting job. The notification determination unit 3307 determines that the start work causes a dangerous event, when the combination of the gaze direction and the start task matches the conditions of the look direction and the start task appearing in the dangerous event list T22.

In addition, when there are two or more workers, the notification determining unit 3307 determines whether or not the combination of the gaze direction and the starting work of the two or more workers meets the condition of the dangerous event list T22 shown in FIG. 9B . Check it. The notification determination unit 3307 determines that the start work generates a dangerous event, when the combination of the gaze direction of two or more workers and the start work matches the condition shown in the dangerous event list T22.
