Description

  The present invention relates to an algorithm editing apparatus and algorithm editing method for editing an operation algorithm of a system.

There is known a system that detects or predicts an abnormality in product quality in a production line, and executes a predetermined operation when the abnormality is detected or predicted. In such a system, an operation rule (operation algorithm) is set that determines a condition for determining an abnormality and an action to be taken when this condition is satisfied. Inspection data obtained from the production line according to the operation rule is analyzed in real time, and when the above condition is satisfied, an operation according to the operation rule is executed. Since the necessary operation rules differ depending on the target product and various situations, in the conventional system, a large number of templates are prepared to correspond to individual operation rules.

And a control unit 33 that receives the determination result in 32 and executes an operation such as stopping the motor or shutting off by a valve.

  Next, the operation of the algorithm editing apparatus 1 will be described.

  FIG. 2 is a diagram showing a display screen when the operation algorithm (operation rule) is set, which is displayed on the display screen 2 by the logic selection accepting unit 13.

  In the display screen of FIG. 2, a list of all logics (three logics in FIG. 2) constituting one operation algorithm is displayed. In the display screen of FIG. 2, the area 21 has a number corresponding to each logic, the area 22 has a check box for switching between valid / invalid for each logic, and the area 23 has a name of each logic. Are displayed respectively. The name of each logic is appropriately input by the user.

  The user can select validity / invalidity of the corresponding logic by operating the check box in the area 22. The operational algorithm is defined as the logical OR (OR) of all the logic that is validated.

  By selecting one logic by an operation on the display screen and operating the “edit” button 24, the logic is selected by the logic selection receiving unit 13, and the display is switched to the display screen by the logic display unit 11.

By connecting these objects to each other by lines, the contents of the selected logic 23b are expressed in an easy-to-understand manner in a diagram format (flow chart or logic chart).

  As in the case of FIG. 3, the logic displayed in the area 27 is edited by the edit receiving means 12 by operating the object on the display screen.

  As described above, one operation algorithm is separated into a plurality of logics and displayed, and editing is accepted for each logic, so that it becomes easy to grasp a complicated operation algorithm and an editing operation is facilitated.

  When the logic is created and edited in the display screen area 27 (FIGS. 3 and 5), the operation algorithm editing unit 14 of the algorithm editing apparatus 1 reflects the logic creation / editing result in the corresponding operation algorithm in real time. . Therefore, the operation algorithm is edited almost simultaneously with the operation according to the operation on the area 27 of the display screen.
