FIG. 2 is a configuration diagram when the above-mentioned start / stop control device is applied to schedule control.

In the figure, (1) is a manual operation control switch, (2) is a control determination means for determining ON / OFF of the manual operation control switch (1), (3) is a clock, and (4) is a schedule control determination means. Therefore, according to the schedule parameter (5), the schedule signal (SC in the flowchart in FIG. 3 is
Abbreviated as HE). Reference numeral (6) is a schedule invalidation judging means for judging a control output signal (abbreviated as SOUT in the flowchart of FIG. 3) depending on the state of the automatic switch (abbreviated as AUTO in the flowchart of FIG. 3). (7) is a control output processing means for controlling the control output (8) and a monitor lamp (not shown). FIG. 3 is a flow chart of a program installed in the microcomputer (14) shown in FIG. The operation of the above embodiment will be described below with reference to this flowchart.

First, in steps (S-1) and (S-2), initial setting of data is performed, and then in step (S-3), time is read.

Start instruction switch (10) in steps (S-4) and (S-5)
When is pressed, the control output result SOUT is set to "1" and the automatic operation state AUTO is set to "0", that is, released. Step (S-
For 6) and (S-7), stop instruction switch (11)
Process.

Automatic instruction switch (12) in steps (S-8) and (S-9)
When is pressed, the automatic operation mode is set, that is, AUTO is set to "1".
Then, the schedule control result SCHE is set to the control output result SOUT.

In step (S-10), the saved time is compared with the current time to determine whether the time has changed. If the time has changed, schedule processing, that is, step (S-
Perform steps 11) to (S-18). On the other hand, if the time has not changed, jump to step (S-19).

Therefore, the above steps (S-11) to (S-14) are processing of the ON time. In step (S-11), it is judged whether the current time is registered as a schedule parameter, and the ON time is determined. If the scheduled time is reached, the schedule control result SCHE is turned ON. That is, it is set to "1".

Also, in steps (S-13) and (S-14), it is determined whether or not it is in the automatic operation state. If it is during the automatic operation, the control output result SOUT
Set the schedule control result SCHE to. Step (S-
15) to (S-18), steps (S-11) to (S-
Similar to 14), it processes the OFF time.

In step (S-19), the final control result is output to the control output (17) via the interface (15), and
It also outputs to the monitor lamp (18).

In step (S-20), the time is saved for checking the time change.

Next, as an actual operation example, a case where the start instruction switch (11) is pressed and then the automatic instruction switch (12) is pressed in the automatic driving state will be described.

First, AUTO is "1" in the automatic operation state, and the schedule control result SCHE is reflected in the control output (17).

Next, when the start instruction switch (1) is pressed, the automatic operation state is released and ON control is output to the control output (17).
After that, the schedule control result SCHE is the control output result SO
It will not be passed to UT and the schedule control will be disabled.
At this time, the schedule result is internally calculated and stored as the schedule control result SCHE.

Next, when the automatic instruction switch (12) is pressed, the automatic operation state is set, and the internally stored schedule control result SCHE is output to the control output (17).

The above-described embodiment can be implemented in the following modes.
