DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work training system using a computer, and more particularly to training for creating work procedures.

[0002]

2. Description of the Related Art A work training system of this kind is prior to the acquisition and succession of various work skills requiring skill, such as various operation works in a plant, accident recovery work and maintenance and inspection work in a monitoring and control system, through on-site training. Then, the work training information such as work manuals and images is sequentially referred to make the work trainer self-taught, and shortage of training time is compensated for by efficient work training.

[0003]

Since the above-mentioned work training information is planar, there is a temporal dependency in a case where there is a partial work and a partial work which needs to be temporally associated therewith. There is no appropriate representation of work when there is a complicated dependency between partial works, such as when there is a procedural dependency such as when parallel work of one partial work and another partial work is required. However, it was difficult for work trainers to understand.

[0011]

FIG. 1 is a system configuration diagram showing an embodiment of the present invention. The database 1 stores the correct work procedure data for each work. When including parallel work in the procedure data, a link is established so as to maintain the temporal dependency or the procedural dependency of the partial work. At this time, a number is assigned to the partial work, and the dependency is expressed by a work number and a symbol (for example, an arrow) or an attribute connecting them.

In the database 1, work condition data such as a moving image during work, a necessary amount of material, and necessary personnel are allocated and stored for each partial work data.

The input section 2 displays a work procedure chart having a time axis on a screen, and assembles the order of partial works required by a work trainee with respect to a given work task (including the parallel work). ), And the input of partial work nodes (data entities representing work) and their link relationships.
FIG. 2 shows an input mode of the input unit 2 to the work chart 2A. In the drawing, a partial work number is input as 1 to 6, and a procedural dependency of the partial work is input as a link displayed by an arrow. The time dependency of the work is input by the difference of the time axis position on the horizontal axis. These input data are temporarily stored in the work chart area 3.

The input unit 2 displays an input screen for work condition data, and enables the work trainer to input work condition data such as materials and personnel required for each partial work on this screen. . These input data are temporarily stored in the work condition area 4.

When the work trainee uses the input unit 2 to input a work procedure, the comparison unit 5 stores the input work procedure data stored in the areas 3 and 4 and the correct work procedure data stored in the database 1. To compare. This comparison checks the correctness of the work procedure, including dependencies, and further checks the correctness of work condition data such as the required material amount and the number of personnel, and determines whether the input of the work trainer is correct, If there is a mistake, the contents of the mistake are output on a screen or the like together with the mistaken part to the work trainer.

The simulation section 6 displays the work procedure input by the work trainer or the work procedure stored in the database 1 in the display area 7 as a moving picture in a time sequence according to the work procedure. This display also displays the images of the materials required for the work.

The simulation section 6 prepares a plurality of moving picture screens and simultaneously displays parallel work. FIGS. 3A to 3F show moving image display examples of parallel work, which will be described below.

(A) The work 1 set first is displayed, and when the reproduction time is over, if there is no parallel work, the work 2 set second is displayed without displaying.

(B) If there is a parallel work, work 2
Is displayed. Work that has been played once does not start playing again.

(C) When another parallel operation 3 is started during the reproduction, the reproduction is terminated and the started operation 3 is displayed.

(D) If the operation is completed during playback,
Stop playback and display other parallel work. At this time, reproduction is not performed by starting the work following the finished work.

(E) If there is no parallel work, or if the parallel work has been reproduced, the subsequent work is displayed.

(F) In the case where priorities are assigned to parallel tasks, when a task with a higher priority is started, the task is displayed in any case.

With the above configuration, the work trainee can use the input unit 2
By inputting the work procedure by the system, the system repeatedly repeats the judgment of the correctness of the work procedure and the output of the judgment result,
The work trainer can learn about the work.

Further, according to the moving picture display method by the simulation section 6, the moving pictures of the parallel work can be sequentially reproduced on one screen, and the reproduction can be performed in consideration of the dependency, so that the work trainer can understand the work procedure and the work contents. Easier to do.

Next, a screen display processing method of a work procedure using the input unit 2 will be described. As described above, when a dependency is set by linking each partial operation, the operation procedure can be accurately expressed, but the implementation of the user interface becomes complicated.

In order to simplify this, the length of each partial work is displayed in multiple image frames based on a certain unit time, and the partial work is displayed at each unit time. The dependency relationship is an expression that starts the next work after the time of the previous work ends.

Therefore, as shown in FIG. 4, the work data is represented by a work table in which work numbers are input to a table having a unit time axis and a parallel work axis instead of the work chart.
Note that, for a time period during which no work is performed, “0” is input for convenience.

FIG. 5 shows an example of the work table screen. The main work and the parallel work are displayed with their display positions shifted.
The work number is assigned in units of 0 minutes, and the contents of the partial work are displayed in a separate frame.

As described above, the length of each partial work is represented by a multiple based on a certain unit time, the simulation display is also performed at each unit time, and the dependency relationship indicates that the time of the previous partial work has ended. By using the expression to start the next partial work later, the user interface is simplified.

[0031]

As described above, according to the present invention, it is possible to include work condition data such as materials that require a correct work procedure for work to be a training subject, store the work condition data in a database, and perform work training. When the worker inputs the work procedure and work condition data for the work of the training task, the judgment is made by comparing with the data of the database, and furthermore, the simulation display is performed according to the work procedure, so that the This has the effect of ensuring and facilitating training for creating procedures for work that is a combination of concurrent work having a dependency.
