DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a structure of a data table on a database in a schedule control device for performing setting for performing schedule control every other week. FIG. 1A shows a format for recording the month to be obtained and the day of the week of the month, and the data of the day of the week is sequentially updated each time after the designated day of the month.

FIG. 1B shows a format of a database for obtaining parameters from the designated day number and the day number of the day. The first byte of this format contains the designated day number and the second byte. In the eighth byte, the numbers of the days of the day are arranged in order of the day of the week (Sunday to Saturday).

FIG. 1C shows a format of a database for obtaining a date. The parameter obtained in FIG. 1B is data of the first byte, and the second to sixth bytes contain weekly data. (The first week, the second week,...).

FIG. 1D shows a format of a database for obtaining the day of the week of the next month. The first byte is the day of the week, and the second to thirteenth records are the first day of the next month. Day number in month order (January, February, ...)
Array. FIGS. 1B to 1D are configured based on FIGS. 3 to 6 described later.

[0013] The schedule control device of this embodiment uses a matrix for bi-weekly schedules.
Easy to implement / update. Here, the matrix used has the following as a database. The parameter is obtained from the day of the day and the specified day of the week.The parameter obtained from the parameter obtained from the specified week and the day of the month is obtained from the day of the specified day. Update by

Next, a specific operation of this embodiment will be described with reference to a flowchart shown in FIG. 2 and data lists shown in FIGS.

Now, an example in which the second and fourth Thursdays of August 1992 are set as bi-weekly schedule control set dates will be described. First, in the format shown in FIG. 1A, the day of the week of August 1 is initialized (the day is Saturday, so the number is 7) based on the day code number table shown in FIG. The number 5 is input as the number of the designated day of the week in FIG. 1B (step S1).

In this state, in FIG.
The parameters when the day is Sunday to Saturday are obtained and stored based on FIG. That is, in this case, since the number of the designated day is 5, each parameter includes “5, 4, 3,
2, 1, 7, 6 "is stored.

Based on the day of the week of August 1 (Saturday, the number is 7) and the designated day of the week (Thursday, the number is 5) input in step S1, the parameters of the designated day are obtained based on FIG. The parameter is set to 1 (c) (step S2). In this case, since Thursday → 5 and Saturday, August 1 → 7, therefore, the parameter = 6 from FIG.

When the parameters are obtained, FIG.
The date of each week is obtained based on the above, and is stored as the date of each week in FIG. In this case, since the parameter is 6, the date of the first to fourth weeks is "6, 13,
20, 27 "is stored (there is no fifth week).

Next, the date of the designated week is obtained by inputting the designated week (steps S3 and S4). That is, since the designated week is the second week, the date of the second Thursday = 13 days is obtained from the format shown in FIG.

If the current date has passed the date obtained in step S4, the fourth Thursday designated next is obtained (steps S5, S8, S2 to S4). On the other hand, if the current date does not exceed the date obtained in step S4, the date designation of the schedule control is rewritten (steps S5 and S6). That is, in the format of the schedule control shown in FIG.
Rewrite the date obtained in step 1.

When the date obtained in step S4 has passed (step S7), it is considered that the schedule control has been executed, and the date of the next designated week (in this case, the fourth Thursday) is set as described above. By performing the schedule control in the same manner as described above, the schedule control is performed every other week (steps S8, S2 to S7).

If there is no next designated week (step S8), the day of the week (September 1) of the next month is determined (step S9). That is, from Saturday, August 1 (Saturday number = 7), the number 3 is obtained based on FIG.
It is required that September 1 of the following month be Tuesday. The day of the week of September 1 of the following month is obtained in advance by the initial setting of the day of the week of August 1 shown in FIG. 1 (a) and stored in the designated place of FIG. 1 (d). It is obtained from the format shown in

Thereafter, this month is updated to September, Tuesday is set as the day of the week (step S10), the contents of FIGS. 1A to 1D are rewritten, and the above steps S1 to S10 are repeatedly executed. Thus, the schedule control based on the designation of every other week is performed.

That is, in the flowchart shown in FIG. 2, steps S1 and S2 constitute a parameter calculating means for obtaining a parameter of the designated day of the week based on the day of the first day of the month. Rewriting means for obtaining the date of the month of the specified week based on the parameters specified, and rewriting the date specification in the date specification field.
An updating means for obtaining and updating the first day of the next month from the first day of the month is configured.

Therefore, according to the above-described embodiment, the date can be obtained by inputting the designated day of the week and the week, and the date automatically updated every month can be obtained. Is rewritten, schedule control can be performed based on the designation of a biweekly day of the week, and the designation of a date can be stored without increasing the memory capacity.

[0026]

As described above, according to the present invention, the data table on the database in which the schedule control parameter for the control target is set is provided with the date designation field in which the date designation can be set, and the current date is set to the date. In a schedule control device that performs schedule control on a control target when a date set in a designated field is reached , a day of the first day of the month is stored in the database.
