2. Description of the Related Art Conventionally, in the production process of a factory, a supervisor directly confirms and analyzes the working conditions of workers and production equipment. Alternatively, the work status is captured by a video camera installed in the factory and displayed on the screen of the display device,
The monitor observes the video on the screen to confirm and analyze the work state, and evaluates, manages, and improves the work state.

In a surveillance system of a factory, a store, etc., a video camera is set on the site, the situation of the work site is picked up by the video camera and displayed on the screen of the display device, and the supervisor monitors the image on the screen. Looking at the situation, I analyzed the situation at the work site and investigated the cause of the abnormal situation.

[0004]

However, conventionally, a supervisor has been used to judge the working condition and the situation of the working site, and the labor cost is wasted accordingly.

Further, the judgment criteria are apt to vary due to the sensitivity and ability of the monitor or the accumulation of experience and know-how in the field. For this reason, strict judgment ability is required of the observers, and the number of the observers is limited. Therefore, the number of supervisors assigned to the work site is small, and it is not possible to constantly monitor all work conditions and work site conditions, so analysis, evaluation, and investigation of the cause of abnormal situations can be performed in real time. I couldn't.

Further, the working state of the worker may change depending on whether or not the monitoring is performed by the monitor. Furthermore, in a large and complicated corporate organization,
Even if there is a problem with the work status of the factory, which is one of the departments, or the situation at the work site, it is difficult to transmit this as it is to the upstream of the organization, and the content of the problem report is suppressed during the transmission, and the work condition It became difficult to reveal the actual situation and problems such as the situation, and hindered their improvement.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and work management capable of analyzing and evaluating a work state, a work site situation, etc. without relying on a supervisor.

In this work management system, the input unit 1
Is for inputting a target work state for each of a plurality of types of work. The target work state is, for example, 1 for highly skilled workers.
It is a moving image that captures a state in which one work is progressing in accordance with a preset work standard and standard time. This moving image is patterned by the input unit 1 using a known image processing method, and then stored in the storage unit 3. To do. Further, the detection unit 2 detects the actual work state of the worker for each normal worker. The actual work state is a moving image in which a normal worker is performing one work, and this moving image is stored in the storage unit 3 after being patterned by the detection unit 2 using a known image processing method. It is stored or given to the central processing unit 4.

The input unit 1 and the detection unit 2 as described above are equipped with a video camera 11 for picking up an image of the work of the worker 12, as shown in FIG. 2, for example.

The role of the situation analysis unit 7 and the instruction warning unit 8 is fulfilled. The state identification unit 5 reads the target work state from the storage unit 3, receives the actual work state from the detection unit 2, compares the target work state with the actual work state, and determines the work speed of the actual work state with respect to the target work state. Determine differences and work procedure errors. For example, by comparing a patterned moving image showing a working state of a highly skilled worker with a patterned moving image showing a working state of a normal worker, a normal moving image for a highly skilled worker is compared. The difference in the work speed of the workers and the error in the work procedure are determined.

The situation analysis section 7 determines whether or not there is an abnormality in the production process based on the status parameter detected by the monitoring section 6. Then, if there is an abnormality in the production process, the situation analysis unit 7 detects the detected status parameter,

The instruction warning unit 7 is notified of this determination result. The instruction warning unit 8 selects an instruction or a warning corresponding to the determination result from various preset instructions or warnings, and displays the selected instruction or warning on the screen of the display device 9 or a speaker. Pronounced from 10. For example, based on the status parameter detected by the monitoring unit 6, the type of trouble of the production apparatus is determined, and an instruction or warning corresponding to the determination result is selected to give an instruction for dealing with the trouble of the production apparatus. The warning is displayed on the screen of the display device 9. Alternatively, based on the difference in the working speed of the normal worker or the error in the work procedure determined by the state identification unit 5,
Work delays, work mistakes, etc. are determined, instructions and warnings corresponding to the judgment results are selected, and instructions and warnings for dealing with work delays, work mistakes, etc. are displayed on the screen of the display device 9.
Furthermore, the determination result and the coping method may be data-communicated to a remote terminal device through a communication line.

Further, the situation analysis unit 7 stores the analysis result at this time in the storage unit 3 as empirical data when an accident such as a trouble, a work delay, and a work error occurs in the production apparatus. This empirical data includes the date and time of the accident, a patterned moving image showing the state of the work of a normal worker, status parameters (production equipment trouble, production process temperature,
Communication status, power supply status, air conditioning status, gas leak, etc.). Further, it is desirable to input the name of the production process, the work item, the worker name, the production capacity, etc. as part of the experience data.

By storing the experience data in the storage unit 3 for each accident in this way, the cause of the accident and countermeasures are clarified with reference to the accumulated experience data, and these are analyzed by the situation analysis unit 7. To improve the accuracy of the analysis.
