In an embodiment of the present invention, the obtained action category of the person is compared with the action category in the action library, and if the person is judged to be normal, the person is continuously monitored within the preset area range.
In another embodiment of the present invention, the steps may further include: counting the duration of normal behaviors and the duration of abnormal behaviors of any person within a preset time, and calculating the work saturation of the person, wherein the calculation mode of the work saturation of the person is the ratio of the duration of normal behaviors to the duration of abnormal behaviors of the person within the preset time.
Counting the duration of normal behaviors and the duration of abnormal behaviors of all people in any post within a preset time, and calculating the working saturation of the post in a mode of calculating the working saturation of the post within the preset time, wherein the ratio of the duration of the normal behaviors to the duration of the abnormal behaviors of all people in the post within the preset time.
For example, in a working day, the time for counting the normal behavior of the employee Zhang III is 420 minutes, the time for counting the abnormal behavior is 80 minutes, and the work saturation of Zhang III is 84%.
In a working day, the sum of the normal behavior time of 5 employees of a machine tool machining post is counted to be 39 hours, the sum of the abnormal behavior time is counted to be 1 hour, and the working saturation of the post is 97.5 percent.
In other embodiments of the present invention, the steps may further include: and allocating the personnel at different posts according to the working saturation of the posts.
For example, a factory has five production lines, each of which has an electric welding station, and it is calculated that the work saturation of the electric welding stations of different production lines is 98%, 92%, 90%, 85%, and 75%, respectively, and it is necessary to allocate employees in the station with low work saturation to the station with high work saturation.
