In the operator position information, the position of the operator detected by the operator position obtaining device 21 is displayed.

The work estimating unit 3304 estimates the work that the operator has started, that is, the start work, based on the detected position of the car, the operation of the operator, and the position of the operator. As a specific example, the work estimating unit 3304 senses that the operator has started the work when the operator uses the terminal device to notify that a new work has been started.

The implementation probability update unit 3305 records the operations performed by the operator, and updates the implementation probability information based on the records. In the implementation probability information system, a combination of multiple operations defined in the order of implementation is described in the plural number. In addition, the implementation probability information system displays the probability of implementing multiple operations included in the combination in the order of implementation for each combination. Therefore, there are cases where a combination of three or more tasks is described in the implementation probability information. In the present embodiment, in order to simplify the description, the description will be made using information describing the implementation probability of a combination of two tasks.

The extraction unit 3306 extracts candidate tasks from candidate tasks. Candidate assignment refers to one or more assignments that have the possibility of performing the next assignment. Alternate work refers to alternate work that has the possibility of a dangerous situation due to implementation. The processing performed in the extraction unit 3306 corresponds to the extraction processing.

Operation-related personnel refer to people related to the operation. The operator-related personnel system includes: a manager who manages the operator, and an assistant who assists the operator. The possibility of occurrence of a dangerous situation is the possibility of occurrence of a dangerous situation due to the execution of the extraction candidate work extracted by the extraction unit 3306. Next, the notification determination unit 3307 outputs a notification determination signal to the notification unit 3308 if it has determined the possibility of notification of the occurrence of a dangerous situation.

The information management unit 341 stores the implementation probability information T10 shown in FIG. 3. In the implementation probability information T10, the system displays plural starting tasks. In addition, in the execution probability information T10, for each start job, candidate jobs that may be performed next to the start job are displayed. In addition, the implementation probability information T10 shows the probability of implementation of the candidate task (implementation probability). In the example of FIG. 3, the work described in the column at the left end is the start work. Next, the work other than the starting work is a candidate work. In Fig. 3, work is started: #001 is followed by candidate work: #001 has a probability of 0.10. In addition, starting job: #001 and then performing candidate job: #002 has a probability of 0.10. In addition, start the assignment: #001 and then implement the alternate assignment: #XXX has a probability of 0.02. The implementation probability information T10 is pre-set for each operator based on the past operation records of each operator. If there are two or more operators, set the implementation probability information T10 for the number of people. In addition, the implementation probability information T10 is updated by the implementation probability update unit 3305 based on the operation record of each operator and the like.

Fig. 4 shows an example of the dangerous situation list T21 of the present embodiment. The dangerous situation storage unit 342 stores the dangerous situation list T21 shown in FIG. 4. In the dangerous situation list T21, the combination of dangerous situation and work is displayed. That is, if the operator performs the work described in the dangerous situation list T21, there is a possibility that the dangerous situation described in the dangerous situation list T21 will occur. The operation shown in Fig. 4 refers to any one of the starting operation and the alternate operation. The dangerous situation list T21 is prepared according to the number of operators. Fig. 4(a) shows a list T21 of dangerous situations when there is one operator. Fig. 4(b) shows a list T21 of dangerous situations when there are two operators. The dangerous situation list T21 in Fig. 4(a) indicates that if the operator 1 performs work: #001, there is a possibility that a dangerous situation: 001 may occur. The dangerous situation list T21 in Fig. 4(b) shows that if the operator 1 performs work: #001, and the operator 2 performs work: #012 in parallel, there is a possibility that a dangerous situation: 011 may occur. The dangerous event list T21 is preset based on past disaster cases, near-miss cases, and the like.

***Description of action*** Next, an example of the operation of the judging device 30 of this embodiment will be described using the flowchart of FIG. 5. The following describes an example where the operator is one person. In addition, explain an example where there are two or more operators.

First, the car position detecting unit 3301 detects the position of the car of the elevator based on the car position information received by the elevator control panel 10 (step S10). Next, the car position detecting unit 3301 notifies the work estimating 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's operation information received from the elevator control panel 10 (step S20). Next, the operator operation signal detecting unit 3302 notifies the operation estimating unit 3304 of the operator's operation.

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

Next, the work estimating unit 3304 estimates the hands-on work of the operator (step S40). Specifically, the work estimating unit 3304 is based on the position of the car notified by the car position detection unit 3301, the operation of the operator notified by the operator operation signal detection unit 3302, and the notification by the operator position detection unit 3303 The position of the operator of the operator is estimated to be the operator’s hands-on work. Specifically, the work estimating unit 3304 refers to the setting information about the position of the machine car during the work, the operation of the operator, and the position of the operator in all the tasks registered in the memory 34 or the auxiliary memory device 40 in advance. The job estimating unit 3304 searches for jobs that match the setting information based on the notified position of the car, the operation of the operator, and the position of the operator, thereby performing job estimation. Among them, the work estimating unit 3304 is to estimate the end of the work when it detects the operator's operation indicating that the work has ended. In addition, the work estimating unit 3304 specifies the number of workers based on the location of the workers. As mentioned above, it is assumed here that the number of operators is one. Next, the work estimating unit 3304 notifies the extraction unit 3306 of the estimated result and the number of workers of the hands-on work. In addition, the work estimation unit 3304 notifies the implementation probability update unit 3305 of the estimation result of the hands-on work.

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

Next, the extraction unit 3306 extracts candidate jobs (step S50). Specifically, the extraction unit 3306 reads out the implementation probability information T10 from the information management unit 341. Next, the extraction unit 3306 extracts candidate tasks based on the implementation probability information T10. To be more specific, the extraction unit 3306 extracts, as a candidate operation, the operation whose probability of subsequent execution of the initial operation notified by the operation estimating unit 3304 exceeds 0. In addition, the extraction unit 3306 reads the dangerous event list T21 from the dangerous event storage unit 342. Next, the extraction unit 3306 extracts candidate jobs included in the dangerous situation list T21 among the extracted candidate jobs as the extraction candidate jobs. Next, the extraction unit 3306 notifies the notification determination unit 3307 of the initial work of the operator, the number of operators, and the extraction candidate work.

Next, the notification determination unit 3307 determines whether or not the starting work has caused a dangerous situation (step S60). Specifically, the notification determination unit 3307 reads the dangerous event list T21 from the dangerous event storage unit 342. Next, the notification determination unit 3307 confirms whether the operator's hands-on 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 determined that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is determined that starting work does not cause a dangerous situation, the process proceeds to step S70.

If it is determined in step S60 that the starting work does not cause a dangerous situation, the notification determination unit 3307 determines whether the implementation probability is higher than the threshold value (step S70). Specifically, in the notification determination unit 3307, the information management unit 341 reads out the implementation probability information T10. Next, the notification determination unit 3307 uses the implementation probability information T10 to extract the implementation probability corresponding to the combination of the initial work and the extraction of the candidate work. In addition, the notification determination unit 3307 compares the extracted implementation probability with the set threshold value. If the implementation probability is higher than the set threshold, the process proceeds to step S80. On the other hand, if the implementation probability is less than the set threshold value, the process proceeds to step S90.

When it is YES in step S60 or YES in step S70, the notification determination unit 3307 determines the possibility of notification of the occurrence of a dangerous situation (step S80). Next, 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 in accordance with the notification decision signal from the notification determination unit 3307.

If it is NO in step S70 or when step S80 is implemented, the implementation probability update unit 3305 senses the end of the work based on the estimation result received by the work estimator 3304 (step S90). If the job ends, the process proceeds to step S100. On the other hand, if the job has not ended, the process proceeds to step S10.

If it is sensed that the work has ended in step S90, the implementation 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 that the operator has worked on is suitable for use as learning materials. In a specific example, the implementation probability update unit 3305 makes the determination in step S100 based on whether the total work time is longer than the set time, or the like. If it is determined that the job satisfies the prescribed criterion, the process proceeds to step S110. On the other hand, if it is not determined that the job meets the prescribed criteria, the processing ends.

If it is determined in step S100 that the operation satisfies a predetermined criterion, the implementation probability update unit 3305 updates the operator's implementation probability information T10 (step S110). As a specific example, the implementation probability update unit 3305 sets the migration of the operation to a Markov chain model or a Bayesian network. In addition, as a specific example, the implementation probability update unit 3305 takes the migration process of a time-series job in the elevator operation as an input, performs the most approximate estimation of the migration rank components, and outputs the migration probability between each job. To update the implementation probability information.

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

As a result of performing step S10 to step S40, if it is determined that there are two or more workers, in step S50, the extracting unit 3306 extracts the extracted combination. More specifically, the extraction unit 3306 extracts candidate tasks for each worker. Next, the extraction unit 3306 combines the extracted candidate tasks of each operator to obtain a combination of plural candidate tasks. In addition, the extracting unit 3306 extracts the combination registered in the dangerous situation list T21 corresponding to the number of workers from among the combinations of the plural candidate tasks as the extracted combination. In addition, the extraction unit 3306 notifies the notification determination unit 3307 of the hands-on work of each operator, the number of operators, and the extraction combination.

Next, in step S60, the notification determination unit 3307 confirms whether the combination of the hands-on work of each worker 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 performing the extraction candidate work of each worker included in the extraction combination. The integrated value is the probability that each operator's candidate work will be performed in parallel. Next, the notification determination unit 3307 compares the integrated value with the set threshold value. If the integrated value is higher than the set threshold value, the process proceeds to step S80. If the integrated value is less than the set threshold value, the process proceeds to step S90. Steps S80 to S110 are as described above, so the description is omitted.

***Explanation of the effect of the implementation form*** As described above, in the present embodiment, the current hands-on work of the operator predicts the possibility of a dangerous situation based on the implementation probability of the candidate work to be performed next. Next, if the possibility of a dangerous situation is high, the notification device is operated. Therefore, according to the present embodiment, the operator can seek preventive safety measures against risks that may be caused in the future. Therefore, the operator can take precautionary actions against future dangers. In addition, in this embodiment, it is also determined whether the current hands-on work itself may cause a dangerous situation to occur. Next, in the present embodiment, if the work is started, there is a high possibility that a dangerous situation will occur, even if the notification device is operated. Therefore, according to the present embodiment, the operator can seek measures to ensure safety at the stage of starting the work if it is not within the prediction based on the candidate extraction work performed in the past.

Implementation form 2. In this embodiment, an example is described in which the control signal invalidation unit invalidates the operator's operation signal if the notification determination unit 3307 determines the possibility of the notification of a dangerous situation. In this embodiment, the difference from Embodiment 1 will be mainly explained. Among them, matters not described below are the same as in the first embodiment.

Fig. 6 is a functional configuration diagram of the judging device 30 of this embodiment. In this embodiment, the determination device 30 is newly provided with a control signal invalidation unit 3309 connected to the elevator control panel 10. Among them, the same components as those in the first embodiment are designated 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. However, the same operations as those in the first embodiment are designated 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 determination unit 3307 determines the possibility of the notification of the occurrence of a dangerous situation (step S120). As a result, the elevator control panel 10 invalidates the operator's operation signal. Among them, the operator operation signal refers to the control signal input to the control panel by the operator when the operator performs the operation of moving the elevator up and down, opening and closing the door, etc. In addition, invalidation means canceling the operator's operation signal and invalidating the operator's operation.

As shown above, if the possibility of a dangerous situation is predicted by carrying out the starting work or extracting alternate work, the operator's operation signal is invalidated and the starting work or extracting alternate work is not performed, which can further improve the work. Security.

Implementation mode 3. In this embodiment, an example is described in which the operator does not face a specific line of sight to perform work, thereby determining the possibility of a dangerous situation. In this embodiment, the difference from Embodiment 2 will be mainly explained. Among them, matters not described below are the same as in the second embodiment.

Fig. 8 is a functional configuration diagram of the judging device 30 of the embodiment. In the present embodiment, the determination device 30 is newly provided with an operator's line-of-sight direction detection unit 3310 connected to the operator's line-of-sight direction acquisition device 22 of the sensor 20. The operator's line-of-sight direction acquiring device 22 acquires the operator's line-of-sight direction. Among them, the same components as those in the second embodiment are designated by the same reference numerals and their descriptions are omitted.

Fig. 9 is an example of a list of dangerous events in the embodiment. The dangerous situation storage unit 342 stores the dangerous situation list T22 shown in FIG. 9. In the dangerous situation list T22, the combination of the dangerous situation, the operator's line of sight direction and the work is displayed. That is, if the operator's line of sight direction is not in the specific direction described in the dangerous event list T22 and the work described in the dangerous event list T22 is performed, there is a possibility that the dangerous event described in the dangerous event list T22 may occur. In a specific example, the above-mentioned specific direction refers to the counterweight direction, the lower direction of the cabin, the top direction of the lifting path, and the like. In addition, the work shown in FIG. 9 is either a start work or a candidate work. The dangerous situation list T22 is prepared according to the number of operators. Fig. 9(a) shows a list T22 of dangerous situations when there is one operator. Fig. 9(b) shows a list T22 of dangerous situations when there are two operators. The dangerous situation list T22 in Fig. 9(a) shows that if the operator 1 does not look at the top of the lifting path and performs work: #101, there is a possibility that a dangerous situation: 101 may occur. In the dangerous situation list T22 of FIG. 9(b), when the operator 1 performs work: #111, and the operator 2 performs work: #112 without viewing the counterweight in parallel, there is a possibility that a dangerous situation: 111 may occur.

Fig. 10 is a flowchart showing an example of the operation of the judging device 30 of the embodiment. Among them, 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 line-of-sight direction detection unit 3310 detects the operator's line-of-sight direction based on the line-of-sight direction information (step S130). The line-of-sight direction information displays the line-of-sight direction of the operator obtained by the line-of-sight direction obtaining device 22 of the operator. Next, the operator's line-of-sight direction detection unit 3310 notifies the extraction unit 3306 of the operator's line-of-sight direction.

After step S40 is completed, the extraction unit 3306 performs extraction of the extraction candidate work using the dangerous situation list T22 (step S500). First, the extraction unit 3306 reads the dangerous event list T22 from the dangerous event storage unit 342. Next, the extraction unit 3306 determines whether the operator's line of sight direction matches the line of sight direction shown in the dangerous situation list T22. If the line of sight direction of the operator matches the line of sight direction 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 extraction unit 3306 extracts a candidate job that matches the job shown in the dangerous situation list T22 among the extracted candidate jobs as the extraction candidate job. If the dangerous situation list T22 shown in Fig. 9(a) is used, when the operator does not see the top of the lifting path, the job is drawn: #101 is the candidate for the drawing. In addition, if there are two or more operators, the extraction unit 306 extracts a combination of candidate jobs of the operator that matches the condition of the dangerous situation list T22 shown in FIG. 9(b) as the extraction combination. Specifically, if any operator does not view the counterweight, the candidate work of the operator who does not view the counterweight is equivalent to work: #112, and the candidate work of the other operator is work: #111 When the extraction unit 306 extracts the work : #112 and homework: #111 are used as an extraction combination. Next, the extracting unit 3306 notifies the notification determination unit 3307 of extracting candidate jobs or extracting combinations.

Next, the notification determination unit 3307 uses the dangerous situation list T22 to determine whether or not the starting work has caused a dangerous situation (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 determination unit 3307 confirms whether the combination of the operator's line-of-sight direction and the estimated hands-on work matches the line-of-sight direction shown in the dangerous situation list T22 and the conditions of the hands-on work. The notification determination unit 3307 determines that the starting work will cause a dangerous situation if the combination of the line-of-sight direction and the hands-on work and the line-of-sight direction shown in the dangerous situation list T22 are consistent with the conditions of the hands-on work. In addition, when there are two or more workers, the notification determination unit 3307 confirms whether the combination of the line of sight of the two or more workers and the hands-on work matches the condition of the dangerous situation list T22 shown in FIG. 9(b). The notification determination unit 3307 determines that if the sight directions of two or more workers match the combination of hands-on work and the conditions shown in the dangerous situation list T22, it is determined that the hands-on work will cause a dangerous situation. Specifically, if any operator does not watch the counterweight, the hands-on work of the operator who does not watch the counterweight is equivalent to work: #112, and the hands-on work of the other operator is work: #111 When the notification decision unit 3307 determines The hands-on work of any operator or all operators can cause dangerous situations. If it is determined that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is determined that starting work does not cause a dangerous situation, the process proceeds to step S70.

Steps S70 to S120 are the same as those described in the first or second embodiment, so the description is omitted.

Among them, in this embodiment, the operation of the extraction unit and the notification determination unit using the dangerous event list T22 is described, but it can also be combined with the dangerous event lists in other embodiments to make extraction and notification decisions.

As described above, in this embodiment, by adding the judgment of the notification decision and the judgment of the operator's line of sight direction, it is possible to improve the prediction accuracy of the possibility of a dangerous situation. Therefore, with this embodiment, the safety of work can be further improved.

Implementation mode 4. In this embodiment, when the physiological state of the operator is in a specific state, an example in which the operator performs work to determine the possibility of a dangerous situation will be described. In this embodiment, the difference from Embodiment 3 will be mainly explained. Among them, matters not described below are the same as in the third embodiment.

Fig. 11 is a functional configuration diagram of the judging device 30 of this embodiment. In the present embodiment, the determination device 30 is newly provided with an operator physiological state detection unit 3311, and is connected to the operator's physiological state acquisition device 23 of the sensor 20. The physiological state acquisition device 23 of the worker detects the physiological state of the worker from the heart rate, body temperature, respiration, and the like. Among them, the physiological state refers to the physical or mental state that has changed due to the passage of time. As a specific example, the physiological state system includes inattentive states that do not focus on work, heat-related disorders such as heat stroke, and stressful states under time constraints such as emergency response. Among them, 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 storage unit 342 stores the dangerous situation list T23 shown in FIG. 12. In the dangerous situation list T23, the combination of the dangerous situation and the physiological state of the operator and the work is displayed. 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 either the start work or the alternate work. The dangerous situation list T23 is prepared according to the number of operators. Fig. 12(a) shows a list T23 of dangerous situations when there is one operator. Fig. 12(b) shows a list T23 of dangerous situations when there are two operators. The dangerous situation list T23 in FIG. 12(a) indicates that if the operator 1 performs work: #201 in a high temperature obstacle state, there is a possibility that a dangerous situation: 201 may occur. The dangerous situation list T23 in FIG. 12(b) indicates that if the operator 1 performs work: #211, and the operator 2 performs work: #212 in a casual state in parallel, there is a possibility that a dangerous situation: 211 may occur.

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

After step S30 is completed, the physiological state detection unit 3311 of the worker detects the physiological state of the worker based on the physiological state information of the worker (step S140). The physiological state information of the operator displays the physiological state of the operator acquired by the physiological state acquiring device 23 of the operator. Next, the physiological state detection unit 3311 of the worker notifies the extraction unit 3306 of the physiological state of the worker.

After step S40 is completed, the extraction unit 3306 performs extraction of the extraction candidate work using the dangerous situation list T23 (step S510). First, the extraction unit 3306 reads the dangerous event list T23 from the dangerous event storage unit 342. Next, the extraction 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 extraction unit 3306 extracts a candidate job that matches the job shown in the dangerous situation list T23 among the extracted candidate jobs as the extraction candidate job. If the dangerous situation list T23 shown in Figure 12 (a) is used, when the operator is in a high temperature obstacle state, the job is drawn: #201 is the candidate job. In addition, when there are two or more workers, the extraction unit 3306 extracts the combination of candidate jobs of the workers that matches the condition of the dangerous situation list T23 shown in FIG. 12(b) as the extraction combination. Specifically, if any operator is inattentive, the candidate assignment of the inattentive operator is equivalent to assignment: #212, and the candidate assignment of the other operator is assignment: #211, when the extraction unit 306 extracts assignment: #212 And homework: #211 as an extraction combination. Next, the extracting unit 3306 notifies the notification determination unit 3307 of extracting candidate jobs or extracting combinations.

Next, the notification determination unit 3307 uses the dangerous situation list T23 to determine whether or not the starting work has caused a dangerous situation (step S610). First, the notification determination unit 3307 reads the dangerous event list T23 from the dangerous event storage unit 342. In addition, the notification determination unit 3307 confirms whether the combination of the physiological state of the operator and the estimated hands-on work is consistent with the physiological state shown in the dangerous situation list T23 and the conditions of the hands-on work. The notification determination unit 3307 determines that if the combination of the physiological state of the operator and the estimated hands-on work and the physiological state shown in the dangerous situation list T23 are consistent with the conditions of the hands-on work, it is determined that the start work will cause a dangerous situation. In addition, when there are two or more workers, the notification determination unit 3307 confirms whether the combination of the physiological state of the two or more workers and the hands-on work matches the condition of the dangerous situation list T23 shown in FIG. 12(b). The notification determination unit 3307 determines that if the physiological state of two or more workers matches the combination of hands-on work and the conditions shown in the dangerous situation list T23, it is determined that the hands-on work will cause a dangerous situation. Specifically, if any operator is inattentive, the hands-on work of the inattentive operator is equivalent to work: #212, and the hands-on work of the other operator is work: #211 When the notification decision section 3307 judges any operator Or the hands-on work of all operators can cause dangerous situations. If it is determined that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is determined that starting work does not cause a dangerous situation, the process proceeds to step S70.

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

In this embodiment, the operation of the extraction unit and the notification determination unit using the dangerous event list T23 is described, but it may be combined with the dangerous event lists in other embodiments to perform extraction and notification decisions.

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

Implementation mode 5. In this embodiment, an example is described in which if the character of the operator is a specific character, the operator performs work to determine the possibility of a dangerous situation. In this embodiment, the difference from Embodiment 4 will be mainly explained. Among them, matters not described below are the same as in the fourth embodiment.

Fig. 14 is a functional configuration diagram of the judging device 30 of this embodiment. In the present embodiment, the determination device 30 is newly provided with an operator character memory unit 343. The worker character storage unit 343 stores the character of each worker set in advance. The personality of the operator includes the temperament of the operator and the ability of the operator. Taking a specific example of the temperament of the operator, it is the temperament of impatience. On the other hand, a specific example of the ability of the operator is the reaction speed of the operator to the stimulus. Among them, the same components as those in the fourth embodiment 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 storage unit 342 stores the dangerous situation list T24 shown in FIG. 15. The dangerous situation list T24 shows the combination of the dangerous situation and the character and work of the operator. That is, if an operator of the personality 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 either the start work or the alternate work. The hazardous situation list T24 is prepared according to the number of operators. Fig. 15(a) shows a list of dangerous situations T24 when there is one operator. Fig. 15(b) shows a list of dangerous situations T24 when there are two operators. The dangerous situation list T24 of Fig. 15(a) shows that if the operator 1 of the acute type performs work: #301, there is a possibility that a dangerous situation: 301 may occur. The dangerous situation list T24 in Fig. 15(b) shows that operator 2 whose reaction speed is relatively slow compared to the average value performs work: #312, and operator 1 performs work in parallel: #311, a dangerous situation occurs: 311 possibility.

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

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

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

Next, the notification determination unit 3307 uses the dangerous situation list T24 to determine whether or not the starting work has caused a dangerous situation (step S620). First, the notification determination unit 3307 reads the dangerous event list T24 from the dangerous event storage unit 342. The notification determination unit 3307 confirms whether the combination of the character of the operator and the presumed hands-on work matches the character and the conditions of the hands-on work shown in the dangerous situation list T24. The notification determination unit 3307 determines that if the combination of the character of the operator and the estimated hands-on work and the character shown in the dangerous situation list T24 are consistent with the conditions of the hands-on work, it is determined that the start work will cause a dangerous situation. In addition, when there are two or more workers, the notification determination unit 3307 confirms whether the combination of the personality of the two or more workers and the hands-on work is consistent with the condition of the dangerous situation list T24 shown in FIG. 15(b). The notification determination unit 3307 determines that if the personality of two or more workers matches the combination of hands-on work and the conditions shown in the dangerous situation list T24, it is determined that the work will cause a dangerous situation. Specifically, if the reaction speed of any operator is quite slow compared to the average value, the hands-on work of the operator with the slow reaction speed is equivalent to work: #312, and the hands-on work of the other operator is work: #311, The notification determination unit 3307 determines that any operator or all operators' hands-on work will cause a dangerous situation. If it is determined that starting work will cause a dangerous situation, the process proceeds to step S80. On the other hand, if it is determined that starting work does not cause a dangerous situation, the process proceeds to step S70.

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

However, in this embodiment, the operation of the extraction unit and the notification determination unit using the dangerous event list T24 is explained, but it can also be combined with the dangerous event lists in other embodiments to make extraction and notification decisions.

As described above, in the present embodiment, by adding the judgment of the operator's character to the judgment of the notification decision, it is possible to improve the prediction accuracy of the possibility of a dangerous situation. Therefore, with this embodiment, the safety of work can be further improved.

Alternatively, among these embodiments, two or more parts may be combined and implemented.
