The dangerous situation list T21 is preset based on past disaster cases, near-miss cases, and the like.

***Description of actions*** Next, an example of the operation of the judging device 30 of this embodiment will be described using the flowchart of FIG. 5 . An example in which there is only one operator will be described below. In addition, an example in which there are two or more operators will be described.

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 ). Next, the car position detection unit 3301 notifies the work estimation unit 3304 of the position of the car.

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

Next, the worker position detection unit 3303 detects the position of the worker based on the worker position information received by the worker position acquisition device 21 (step S30 ). Next, the worker position detection unit 3303 notifies the work estimation unit 3304 of the position of the worker.

Next, the work estimation unit 3304 estimates the work to be done by the operator (step S40 ). Specifically, the work estimation unit 3304 is notified by the operator position detection unit 3303 based on the position of the car notified by the car position detection unit 3301 , the operator's operation notified by the operator operation signal detection unit 3302 The operator's position is estimated, and the operator's work is estimated. Specifically, the operation estimating unit 3304 refers to setting information about the position of the car during the operation, the operation of the operator, and the position of the operator among all the operations registered in the memory 34 or the auxiliary memory device 40 in advance. The job estimation unit 3304 performs job estimation by searching for a job that matches the setting information from the notified position of the car, the operation of the operator, and the position of the worker. Here, when the job estimation unit 3304 detects an operator's operation indicating that the job is finished, it estimates that the job is finished. In addition, the work estimation unit 3304 specifies the number of workers from the position of the workers. As mentioned above, it is assumed here that the number of workers is one. Next, the work estimation unit 3304 notifies the extraction unit 3306 of the estimated result of the work to be performed and the number of workers. In addition, the work estimation unit 3304 notifies the execution probability update unit 3305 of the estimation result of the work to be started.

However, in the present embodiment, the work estimation unit 3304 estimates the start of work based on the position of the car, the operation of the operator, and the position of the operator. However, for example, if the operator uses a terminal device to notify the determination device 30 of the work to be started, steps S10 to S40 may be omitted.

Next, the extraction unit 3306 extracts extraction candidate jobs (step S50 ). Specifically, the extraction unit 3306 reads out the implementation probability information T10 from the information management unit 341 . Next, the extracting unit 3306 extracts candidate jobs based on the execution probability information T10. More specifically, the extracting unit 3306 extracts, as a candidate task, a task whose probability of subsequent execution of the starting task notified from the task estimating unit 3304 exceeds 0. In addition, the extracting unit 3306 reads the dangerous situation list T21 from the dangerous situation storage unit 342 . Next, the extracting unit 3306 extracts the candidate jobs included in the dangerous situation list T21 among the extracted candidate jobs as extraction candidate jobs. Next, the extraction unit 3306 notifies the notification determination unit 3307 of the operator's work to be performed, the number of workers, and the extracted candidate work.

Next, the notification determination unit 3307 determines whether or not a dangerous situation is caused by the starting work (step S60 ). Specifically, the notification determination unit 3307 reads the dangerous situation list T21 from the dangerous situation storage unit 342 . Next, the notification determination unit 3307 checks whether the operator's work is included in the dangerous situation list T21. If the starting work is included in the dangerous situation list T21, the notification determination unit 3307 determines that the starting work will cause a dangerous situation. If it is judged that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is judged that starting the work will not cause a dangerous situation, the process proceeds to step S70.

If it is judged in step S60 that the start-up operation will not cause a dangerous situation, the notification determination unit 3307 judges whether the execution probability is higher than a threshold value (step S70 ). Specifically, the notification determination unit 3307 reads out the implementation probability information T10 from the information management unit 341 . Next, the notification determination unit 3307 extracts the implementation probability corresponding to the combination of the starting operation and the extracted candidate operation from the implementation probability information T10. In addition, 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 value, the process proceeds to step S80. On the other hand, if the implementation probability is less than or equal to the set threshold value, the process proceeds to step S90.

When YES in step S60 or YES in step S70 , the notification determination unit 3307 determines the possibility of reporting the occurrence of a dangerous situation (step S80 ). Next, the notification determination unit 3307 outputs a notification decision signal to the notification unit 3308 . The notification unit 3308 transmits a notification command to the notification device 50 according to the notification determination signal from the notification determination unit 3307 .

If NO in step S70 or when step S80 is performed, the implementation probability update unit 3305 senses the completion of the task based on the estimation result received by the task estimation unit 3304 (step S90 ). If 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 sensed in step S90 that the work has been completed, the execution probability update unit 3305 determines whether the work performed by the operator satisfies a predetermined 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 materials. As a specific example, the execution probability update unit 3305 performs the determination in step S100 according to whether the total work time is longer than the set time or not. If it is determined that the job satisfies the predetermined standard, the process proceeds to step S110. On the other hand, if it is not determined that the job satisfies the predetermined standard, the process ends.

If it is determined in step S100 that the operation satisfies the predetermined criteria, the execution probability update unit 3305 updates the execution probability information T10 of the operator (step S110 ). As a specific example, the execution probability update unit 3305 sets the transition of the job as a Markov chain model or a Bayesian network. In addition, as a specific example, the implementation probability update unit 3305 takes as input the transition process of the time-series tasks in the lift operation, performs the most probable estimation of the components of the transition matrix, and outputs the transition probabilities between the tasks, Use this to update the fulfillment probability information.

Next, an example of the operation of the determination device 30 when there are two or more workers will be described.

As a result of performing steps S10 to S40, if it is determined that there are two or more operators, in step S50, the extraction unit 3306 extracts the extraction combination. More specifically, the extraction unit 3306 extracts job candidates for each operator. Next, the extraction unit 3306 combines the extracted candidate jobs of each operator to obtain a combination of a plurality of candidate jobs. Furthermore, the extracting unit 3306 extracts, as an extracted combination, a combination registered in the dangerous situation list T21 corresponding to the number of workers among the combinations of the plurality of candidate jobs. In addition, the extraction unit 3306 notifies the notification determination unit 3307 of the work to be done by each operator, the number of operators, and the extraction combination.

Next, in step S60 , the notification determination unit 3307 checks whether or not the combination of each worker's work is included in the dangerous situation list T21 corresponding to the number of workers. If the combination of the work to be started is included in the dangerous situation list T21, the process proceeds to step S80. On the other hand, if the combination of the work to be started is not included in the dangerous situation list T21, the process proceeds to step S70.

In step S70 , the notification determination unit 3307 accumulates the probability of executing the extraction candidate work of each operator included in the extraction combination. The integrated value is the probability of performing the candidate work of each operator in parallel. Next, the notification determination unit 3307 compares the integrated value with the set threshold value. If the accumulated value is higher than the set threshold value, the process proceeds to step S80. If the accumulated value is less than or equal to the set threshold value, the process proceeds to step S90. Step S80 to step S110 are described above, so the description is omitted.

***Explanation of the effect of the embodiment*** As described above, in this embodiment, the possibility of occurrence of a dangerous situation is predicted based on the operator's current work and the execution probability of the next candidate work. Next, if the possibility of occurrence of a dangerous situation is high, the notification device is activated. Therefore, according to the present embodiment, the operator can take preventive safety measures against risks that may arise in the future. Therefore, the operator can take avoidance actions in advance for future dangers. In addition, in this embodiment, it is also judged whether the current work itself has the possibility of causing a dangerous situation. Next, in this embodiment, if there is a high possibility that a dangerous situation will occur due to the start of work, the notification device will be activated. Therefore, according to the present embodiment, the operator can take measures to ensure safety at the stage of starting work unless it is within the prediction based on the extraction of candidate work performed previously.

Implementation form 2. In this embodiment, an example will be described in which the control signal invalidation section invalidates the operator's operation signal when the notification determination section 3307 determines the possibility of notification of the occurrence of a dangerous situation. In this embodiment, differences from Embodiment 1 will be mainly described. However, matters not described below are the same as those in the first embodiment.

Fig. 6 is a diagram showing the functional configuration of the judging device 30 of the present embodiment. In the present embodiment, the judging device 30 newly includes a control signal invalidation unit 3309 connected to the elevator control panel 10 . Here, the same components as those in Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted.

Fig. 7 is a flowchart showing an example of the operation of the judging device 30 of the embodiment. Here, the same operations as those in the first embodiment are denoted by the same reference numerals and their descriptions are omitted.

The control signal invalidation unit 3309 transmits a signal for invalidating the operator's operation signal to the elevator control panel 10 when the notification decision unit 3307 determines the possibility of the notification of a dangerous situation (step S120 ). As a result, the elevator control panel 10 invalidates the operator's operation signal. Here, the operator's operation signal refers to a control signal that the operator inputs to the control panel when the operator performs operations such as moving the elevator up and down, opening and closing doors, and the like. In addition, invalidation means canceling the operator's operation signal and invalidating the operator's operation.

As mentioned above, if the possibility of the occurrence of a dangerous situation is predicted by performing the starting work or drawing out the candidate work, the operation can be further improved by invalidating the operator's operation signal and making the starting work or drawing out the candidate work not performed. security.

Implementation form 3. In this embodiment, an example is described in which the possibility of occurrence of a dangerous situation is judged by an operator performing work without facing a specific line of sight. In this embodiment, differences from Embodiment 2 will be mainly described. However, matters not described below are the same as those in the second embodiment.

Fig. 8 is a diagram showing the functional configuration of the judging device 30 of the embodiment. In this embodiment, the judging device 30 newly includes: an operator's gaze direction detection unit 3310 , which is connected to the operator's gaze direction acquisition device 22 of the sensor 20 . The operator's line-of-sight direction acquiring device 22 acquires the line-of-sight direction of the operator. Here, the same components as those in Embodiment 2 are denoted by the same reference numerals and their descriptions are omitted.

Fig. 9 is an example of a list of dangerous situations in the embodiment. The dangerous situation memory unit 342 stores the dangerous situation list T22 shown in FIG. 9 . The dangerous situation list T22 displays combinations of the dangerous situation, the line of sight direction of the operator, and the work. That is, if the operator's gaze direction is not in the specific direction described in the dangerous situation list T22 and the operation described in the dangerous situation list T22 is performed, the dangerous situation described in the dangerous situation list T22 may occur. As a specific example, the above-mentioned specific direction refers to the direction of the counterweight, the direction of the bottom of the cabinet, the direction of the top of the lifting path, and the like. In addition, the work shown in FIG. 9 is any one of a starting work and a candidate work. Dangerous situation list T22 is prepared according to the number of workers. FIG. 9( a ) shows the dangerous situation list T22 when there is one worker. FIG. 9( b ) shows the dangerous situation list T22 when there are two workers. The dangerous situation list T22 in FIG. 9( a ) shows that when the operator 1 performs the work: #101 without looking at the top of the ascending and descending path, there is a possibility that the dangerous situation: 101 will occur. In the dangerous situation list T22 of FIG. 9( b ), when the operator 1 performs the work: #111 and the worker 2 performs the work: #112 in parallel without looking at the counterweight, there is a possibility that the dangerous situation: 111 will occur.

Fig. 10 is a flowchart showing an example of the operation of the judging device 30 of the embodiment. However, the same operations as those in the second embodiment are denoted by the same reference numerals and their descriptions are omitted.

After step S30 is completed, the operator's gaze direction detection unit 3310 detects the operator's gaze direction according to the gaze direction information (step S130 ). The gaze direction of the operator acquired by the operator's gaze direction acquisition device 22 is displayed in the gaze direction information system. Next, 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 extracting unit 3306 extracts candidate extraction jobs using the dangerous situation list T22 (step S500 ). First, the extracting unit 3306 reads the dangerous situation list T22 from the dangerous situation storage unit 342 . Next, the extracting unit 3306 determines whether the operator's line of sight coincides with the line of sight indicated in the dangerous situation list T22. If the operator's line of sight coincides with the line of sight shown in the dangerous situation list T22, the extraction unit 3306 extracts candidate tasks in the same manner as in the first embodiment. In addition, the extracting unit 3306 extracts a candidate job that matches the job shown in the dangerous situation list T22 from among the extracted candidate jobs, as an extraction candidate job. If the dangerous situation list T22 shown in FIG. 9( a ) is used, when the operator does not look at the top of the lifting path, extraction operation: #101 is used as an extraction candidate operation. In addition, if there are two or more workers, the extracting unit 306 extracts, as an extracted combination, a combination of candidate tasks of workers matching the conditions of the dangerous situation list T22 shown in FIG. 9( b ). Specifically, if any operator does not view the counterweight, the candidate operation of the operator who does not view the counterweight corresponds to operation: #112, and when the candidate operation of the other operator is operation: #111, the extraction unit 306 is the extraction operation. : #112 and job: #111 are extracted combinations. Next, the extraction unit 3306 notifies the notification determination unit 3307 of the extraction candidate job or the extraction combination.

Next, the notification determination unit 3307 uses the dangerous situation list T22 to judge whether or not the dangerous situation is caused by the work to be started (step S600 ). First, the notification determination unit 3307 reads the dangerous situation list T22 from the dangerous situation storage unit 342 . In addition, the notification determination unit 3307 checks whether the combination of the operator's line of sight and the estimated starting work matches the conditions of the line of sight and starting work shown in the dangerous situation list T22. The notification determination unit 3307 judges that the starting operation will cause a dangerous situation if the combination of the viewing direction and the starting operation and the viewing direction shown in the dangerous situation list T22 match the conditions of the starting operation. In addition, if there are two or more workers, the notification determination unit 3307 checks whether the combination of the line of sight direction and the starting work of the two or more workers matches the conditions of the dangerous situation list T22 shown in FIG. 9( b ). The notification determination unit 3307 determines that the starting work will cause a dangerous situation if the line of sight directions of two or more workers matches the combination of the starting work and the condition shown in the dangerous situation list T22. Specifically, if any operator has not checked the counterweight, the operator who has not looked at the counterweight's operation is equivalent to operation: #112, and when the other operator's operation is operation: #111, the notification determination part 3307 is determined Hands-on work by any operator or all operators can cause a dangerous situation. If it is judged that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is judged that starting the work will not cause a dangerous situation, the process proceeds to step S70.

Step S70 to step S120 are the same as those described in Embodiment 1 or Embodiment 2, so the description is omitted.

In this embodiment, the operations of the extracting unit and the notification determination unit using the dangerous situation list T22 are described, but the extraction and notification determination can be performed in combination with the dangerous situation list in other embodiments.

As described above, in this embodiment, by adding the determination of the operator's line of sight to the determination of notification determination, the prediction accuracy of the possibility of occurrence of a dangerous situation can be improved. Therefore, according to this embodiment, the safety of work can be further improved.

Implementation form 4. In this embodiment, an example is described in which the possibility of occurrence of a dangerous situation is judged by an operator performing work when the operator's physiological state is in a specific state. In this embodiment, differences from Embodiment 3 will be mainly described. However, matters not described below are the same as those of the third embodiment.

Fig. 11 is a diagram showing the functional configuration of the judging device 30 of the present embodiment. In the present embodiment, the judging device 30 newly includes an operator's physiological state detection unit 3311 , and is connected to the operator's physiological state acquiring device 23 of the sensor 20 . The operator's physiological state acquisition device 23 detects the operator's physiological state from heart rate, body temperature, respiration, and the like. Here, the physiological state refers to a physical or mental state that changes with the lapse of time. As a specific example, the physiological state includes a state of being inattentive without concentrating on work, a state of high-temperature disturbance such as heatstroke, and a state of stress under tight time such as emergency response. Here, the same components as those in the third embodiment are denoted by the same reference numerals and their descriptions are omitted.

FIG. 12 is an example of the dangerous situation list T23 of this embodiment. The dangerous situation memory unit 342 stores the dangerous situation list T23 shown in FIG. 12 . The dangerous situation list T23 displays combinations of the dangerous situation, the physiological state of the worker, and the work. That is, if the operator performs the work described in the dangerous situation list T23 in the physiological state described in the dangerous situation list T23, there is a possibility that the dangerous situation described in the dangerous situation list T23 will occur. The work shown in FIG. 12 is any one of the starting work and the standby work. Dangerous situation list T23 is prepared according to the number of workers. FIG. 12( a ) shows the dangerous situation list T23 when there is one worker. FIG. 12( b ) shows the dangerous situation list T23 when there are two workers. The dangerous situation list T23 in FIG. 12( a ) indicates that there is a possibility that the dangerous situation: 201 will occur if the worker 1 performs the work: #201 in the high temperature failure state. The dangerous situation list T23 in FIG. 12( b ) shows that if the worker 1 performs the work: #211, and the worker 2 performs the work: #212 in a careless state in parallel, there is a possibility that the dangerous situation: 211 will occur.

Fig. 13 is a flowchart showing an example of the operation of the judging device 30 of this embodiment. However, the same operations as those in the third embodiment are denoted by the same reference numerals and their descriptions are omitted.

After step S30 is completed, the operator's physiological state detection unit 3311 detects the operator's physiological state according to the operator's physiological state information (step S140 ). The physiological state information of the worker displays the physiological state of the worker acquired by the device 23 for obtaining the physiological state of the worker. Next, the worker's physiological state detection unit 3311 notifies the extraction unit 3306 of the worker's physiological state.

After step S40 is completed, the extracting unit 3306 extracts candidate extraction jobs using the dangerous situation list T23 (step S510 ). First, the extracting unit 3306 reads the dangerous situation list T23 from the dangerous situation storage unit 342 . Next, the extracting unit 3306 determines whether the physiological state of the worker matches the physiological state shown in the dangerous situation list T23. If the physiological state of the worker matches the physiological state shown in the dangerous situation list T23, the extraction unit 3306 extracts candidate tasks in the same manner as in the first embodiment. In addition, the extracting unit 3306 extracts a candidate job that matches the job shown in the dangerous situation list T23 from among the extracted candidate jobs, as an extraction candidate job. If the dangerous situation list T23 shown in FIG. 12( a ) is used, when the operator is in a state of high temperature failure, the extraction operation: #201 is used as an extraction candidate operation. Also, if there are two or more workers, the extracting unit 3306 extracts, as an extracted combination, combinations of candidate tasks of workers that match the conditions of the dangerous situation list T23 shown in FIG. 12( b ). Specifically, if any operator is in the inattentive state, the candidate operation of the operator in the inattentive state corresponds to operation: #212, and when the candidate operation of the other operator is operation: #211, the extraction unit 306 extracts operation: #212 Combination with assignment: #211 as extraction. Next, the extraction unit 3306 notifies the notification determination unit 3307 of the extraction candidate job or the extraction combination.

Next, the notification determination unit 3307 uses the dangerous situation list T23 to judge whether or not the dangerous situation is caused by the work to be started (step S610 ). First, the notification determination unit 3307 reads the dangerous situation list T23 from the dangerous situation storage unit 342 . In addition, the notification determination unit 3307 checks whether the combination of the operator's physiological state and the estimated starting work matches the physiological state and starting work conditions shown in the dangerous situation list T23. The notification determination unit 3307 judges that starting the work will cause a dangerous situation if the combination of the operator's physiological state and the estimated starting work and the physiological state shown in the dangerous situation list T23 match the conditions of starting the work. In addition, if there are two or more workers, the notification determination unit 3307 checks whether the combination of the physiological state and the work to be performed by the two or more workers matches the conditions of the dangerous situation list T23 shown in FIG. 12( b ). The notification determination unit 3307 judges that the starting work will cause a dangerous situation if the physiological state of two or more workers matches the combination of the starting work and the conditions shown in the dangerous situation list T23. Specifically, if any operator is in a careless state, and the operator's work in the careless state is equivalent to work: #212, and the other operator's work is work: #211, the notification decision unit 3307 determines that any operator Or the manual operation of all operators may cause a dangerous situation. If it is judged that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is judged that starting the work will not cause a dangerous situation, the process proceeds to step S70.

Step S70 to step S120 are the same as those described in Embodiment 1 to Embodiment 3, so the description is omitted.

In this embodiment, the operations of the extracting unit and the notification determination unit using the dangerous situation list T23 are described, but the extraction and notification determination may be performed in combination with the dangerous situation list in other embodiments.

As described above, in this embodiment, the determination of the operator's physiological state is also added to the determination of notification decision, thereby improving the prediction accuracy of the possibility of occurrence of a dangerous situation. Therefore, according to this embodiment, the safety of work can be further improved.

Implementation form 5. In this embodiment, an example will be described in which the possibility of occurrence of a dangerous situation is judged by an operator performing an operation if the operator has a specific personality. In this embodiment, differences from Embodiment 4 will be mainly described. However, matters not described below are the same as those of the fourth embodiment.

Fig. 14 is a diagram showing the functional configuration of the judging device 30 of the present embodiment. In this embodiment, the judging device 30 newly includes an operator personality memory unit 343 . The worker personality memory unit 343 stores the preset personality of each worker. The operator's character system includes the operator's temperament and operator's ability. A specific example of an operator's temperament is an impatient temperament. On the other hand, a specific example of the worker's ability is the worker's reaction speed to a stimulus. Here, the same components as those in Embodiment 4 are denoted by the same reference numerals and their descriptions are omitted.

FIG. 15 is an example of the dangerous situation list T24 of this embodiment. The dangerous situation memory unit 342 stores the dangerous situation list T24 shown in FIG. 15 . The dangerous situation list T24 shows combinations of dangerous situations, personalities of operators, and tasks. That is, if the worker with the character described in the dangerous situation list T24 performs the work described in the dangerous situation list T24, there is a possibility that the dangerous situation described in the dangerous situation list T24 will occur. The work shown in FIG. 15 is any one of the starting work and the standby work. Dangerous situation list T24 is prepared according to the number of workers. FIG. 15( a ) shows the dangerous situation list T24 when there is one worker. FIG. 15( b ) shows the dangerous situation list T24 when there are two workers. The dangerous situation list T24 in FIG. 15( a ) indicates that there is a possibility that the dangerous situation: 301 will occur if the impatient operator 1 performs the work: #301. The dangerous situation list T24 in Fig. 15(b) shows that when the operator 2 whose response speed is relatively slow compared to the average value performs the task: #312, and the worker 1 executes the task: #311 in parallel, a dangerous situation may occur: 311 possibilities.

Fig. 16 is a flowchart showing an example of the operation of the judging device 30 of this embodiment. Here, the same operations as those in the fourth embodiment are denoted by the same reference numerals and their descriptions are omitted.

After step S40 is completed, the extracting unit 3306 acquires the personality of the worker from the worker personality storage unit 343 (step S150 ).

Next, the extraction unit 3306 extracts the extraction candidate job using the dangerous situation list T24 (step S520 ). First, the extracting unit 3306 reads the dangerous situation list T24 from the dangerous situation storage unit 342 . Next, the extracting unit 3306 judges whether the personality of the worker matches the personality shown in the dangerous situation list T24. If the character of the worker matches the character shown in the dangerous situation list T24, the extracting unit 3306 extracts candidate tasks in the same manner as in the first embodiment. In addition, the extracting unit 3306 extracts a candidate job that matches the job shown in the dangerous situation list T24 from among the extracted candidate jobs, as an extraction candidate job. Using the dangerous situation list T24 shown in FIG. 15( a ), when the operator's personality is impatient, the operation: #301 is extracted as an extraction candidate operation. Also, if there are two or more workers, the extracting unit 3306 extracts, as an extracted combination, combinations of candidate tasks of workers that match the conditions of the dangerous situation list T24 shown in FIG. 15( b ). Specifically, if the reaction speed of any operator is relatively slow compared to the average value, and the candidate job of the operator with the slow reaction speed corresponds to job: #312, and the job candidate job of the other worker is job: #311, The extraction unit 306 extracts job: #312 and job: #311 as an extraction combination. Next, the extraction unit 3306 notifies the notification determination unit 3307 of the extraction candidate job or the extraction combination.

Next, the notification determination unit 3307 uses the dangerous situation list T24 to judge whether or not the dangerous situation is caused by the work to be started (step S620 ). First, the notification determination unit 3307 reads the dangerous situation list T24 from the dangerous situation storage unit 342 . The notification determination unit 3307 checks whether the combination of the personality of the operator and the estimated operation is consistent with the conditions of the personality and operation shown in the dangerous situation list T24. The notification determination unit 3307 judges that starting the work will cause a dangerous situation if the combination of the operator's character and the estimated starting work and the character shown in the dangerous situation list T24 match the conditions of starting the work. In addition, if there are two or more workers, the notification determination unit 3307 checks whether the combination of the personalities of the two or more workers and the work to be done matches the conditions of the dangerous situation list T24 shown in FIG. 15( b ). The notification decision unit 3307 judges that the starting work will cause a dangerous situation if the combination of personalities of two or more workers and the combination of the starting work and the conditions shown in the dangerous situation list T24 match. Specifically, if the reaction speed of any operator is considerably slower than the average value, and the operator with the slow reaction speed is working on assignment: #312, and the other operator is working on assignment: #311, The notification determination unit 3307 determines that any operator or all operators' work will cause a dangerous situation. If it is judged that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is judged that starting the work will not cause a dangerous situation, the process proceeds to step S70.

Step S70 to step S120 are the same as those described in Embodiment 1 to Embodiment 4, so the description is omitted.

In this embodiment, the operations of the extracting unit and the notification determination unit using the dangerous situation list T24 are described, but the extraction and notification determination may be performed in combination with the dangerous situation list in other embodiments.

As described above, in the present embodiment, by adding the determination of the operator's personality to the determination of the notification decision, the prediction accuracy of the possibility of occurrence of a dangerous situation can be improved. Therefore, according to this embodiment, the safety of work can be further improved.
