2k<, and the power failure compensation function selection switch 2
, by turning off the microcomputer 6
can be reset). In addition, the operation of the output unit 5 includes a timer operation that sets the on/off time of the control equipment,
There is a pulse operation in which the control device is repeatedly turned on and off for a certain period of time, and one of these operations can be selected using the operation state changeover switches 2k, 2k. In addition, in the following explanation, the case where this time switch is operated as a timer will be explained.

The setting operation for setting the current time in this embodiment will be explained. In this case, first, the mode switch 2a is switched to the mode for setting the current time. At this time, the time display section 12m of the liquid crystal display 12 is fixed except for the 1 second display section 12.
The numerical values are advanced by pressing the hour 1 degree and minute 1 setting switches 2 d and 2 e multiple times until the hour display section 12d and minute display section 12e reach the desired hours and minutes, respectively. Set by. [Second 1 setting switch 2j] The moment you press and release the switch 2j, the display starts from 0 seconds to 1 second and 1. By pressing and releasing the second setting switch 2j after setting 1 o'clock and 1 minute, you can change the display to 1 second. Set. In addition, if it is necessary to change the day of the week, the day of the week can be changed using the day of the week switches 2c and 2ct. Then, by switching the mode switch 2a to the normal mode, the current time setting operation is completed.

Next, the program settings for turning the control device on and off will be explained. In this case, the setting changeover switch 2k3.2k needs to be switched so that the time switch performs the time operation.

First, the mode switch 2a is switched to the setting mode.

In this state, the "hour - 1", "minute" display section 12d of the time display section 12a where the current time of the liquid crystal display 12 was displayed,
12e, as shown in FIG. 10(a), [-1:--
J, and the output display section 12c on the left side of this display shows jON.
The symbol J is displayed. Note that "ON" displayed on the output display section 12c in the normal mode is a display indicating that the control device is in the on state, and in the setting mode, the "ONJ display" indicates that the time to be input from now is the control device. Numerical values from 1 to 16 are displayed in the "second" display 2r of the time display, which indicates the time to turn on the device. This numerical value is the remaining setting number indicating the number of programs that can be set, and by looking at this remaining setting number, the user can confirm the number of programs or the set capacity. And 1 o'clock", 1 minute" setting switch 2 d, 2
At e, the time to turn on the control device is set in the same way as in the case of setting the time to the present time described above. In addition, the day of the week can be set using the day switch 2cl to 26? For example, turn on the control equipment at the above times from Monday to Friday.

If you want to turn it off, press the appropriate day switch 2c of the day switches 2cl to 2e7. This day of the week switch 2
When c is pressed, the day of the week display section 12b is displayed. FIG. 10(b) shows the display state of the liquid crystal display 12 when the ON time of the control device 11 is set in this way. This is set by pressing the "second" setting switch 2f, which also serves as the "second" setting switch 2f. When this "second" setting switch 2f is pressed, "hour" and "1 minute" will be displayed automatically on the liquid crystal display 12.
d, 2 e, as shown in FIG. 10(d), r--
The state becomes Knee-J, and the [ON] display on the output display section 12c on the left side of this display changes to the [0FFJ display]. In the case of this embodiment, the ON and OFF times of the AM controller are set as a set, and the setting of only the ON time and OFF time must be set as a set or the microcomputer 6 will not accept it. There is no such thing. At this time, the remaining setting number is one less than the value at the time of setting the ON time of the control device. Then, the off time of the control device is set in the same manner as the on time described above. In the case of this embodiment, up to 16 operations can be set, with each of the ON time setting and OFF time setting of the control device being one operation. Therefore, the remaining number of settings when no programming is performed is 16, and the remaining number of settings decreases by 2 each time one program is performed. By checking the remaining number of settings, the user can confirm whether or not the time has been set reliably. When this program setting is completed, the display on the liquid crystal display 12 will be as shown in Figure 10 (
As shown in e), the initial state at the time of setting the on time is reached, and the control equipment is then turned on.

You can set the off time. This program setting is completed by switching the mode switch 2a to the normal mode. Here, the processing by the microcomputer 6 in the above program setting is as shown in Figure 1jIJ11. In other words, since the mode switch 2a of the microcomputer 6 has been switched to the setting mode, the operation shifts to displaying the remaining number of settings, and if the number of settings remaining remains, the series of operations described above is executed. When there is no remaining setting number, "0" is displayed as the remaining setting number, and the operation is terminated without receiving the input signal from the switch operation section 2. When erasing this program setting, the mode switch 2a is switched to the setting mode in the same manner as in the case of the above-mentioned program setting. By pressing the erase switch 2j in this state, one program that sets the on and off times of the control equipment is erased. In the case of this embodiment, the remaining number of settings increases by two. Therefore, the user can check whether the settings have been definitely deleted by checking the remaining number of settings.

Incidentally, since the on and off set times of the control equipment are set as one set, the program can be erased even when the off time of the control equipment is displayed on the liquid crystal display 12.

Please note that the above explanation is based on a typical electronic time switch.
Although the explanation was about the same operation as the program setting for a day or less, in this embodiment, it is possible to set a day program for two or more days as follows. The setting procedure for this day crossing setting is almost the same as the setting procedure for the program setting described above. However, in this embodiment, when setting the program for setting the on/off times of the control equipment, it is possible to set the programs for different days of the week, thereby enabling day-to-day settings. In other words, in this embodiment, the set day of the week detecting means detects that the days of the week on which the on time and off time of the control device are set are different, and the day of the week on which the on time and off time of the control device are set are the same. A set time detection means is provided for detecting that the on set time is later than the off set time, and the rain detecting means can be used to set the old crossing. The operations of the set day of the week detecting means and the set time detecting means are performed by software of the microcomputer 6. For example, as shown in FIG. 12, if the control equipment is to be operated from 12:00 on Monday to 12:00 on Thursday, the control is applied.

Monday and the time are set when setting the day of the week for the on-setting time of the goblin, and Thursday and the time are set when setting the off-setting time. In this case, since the days of the week are different, the day-of-the-week detection means of the microcomputer 6 detects that it is a day-to-day setting, and the day-to-day setting is automatically performed. Furthermore, even if the ON setting time is later than the OFF setting time on the same day of the week, the setting time detection means of the microcomputer 6 will detect that the setting is for daywalking.
The day crossing setting will be done automatically. Incidentally, FIG. 13 shows a 70-chart showing the determination processing program by the microcomputer 6 for the above-mentioned day crossing setting. In this way, daily settings can be made with one program similar to the program settings for within one day, so the complexity at the time of setting can be reduced and the program capacity can also be reduced. Incidentally, since it is impossible for the ON and OFF setting times to be the same on the same day of the week, the microcomputer 6 is configured to perform error processing at this time.

Furthermore, this embodiment is provided with a day-of-the-week changing function, which will be described below. For example, as shown in Figure 2(a), for one week, the control equipment is operated from 8:00 to 20:00 on all other days of the week except Sunday, and the control equipment is operated only from 16:00 to 20:00 on Sundays. It is assumed that a time schedule has been established. Assume that next week's Tuesday and Wednesday are holidays, ζ, so it is sufficient to operate the control equipment in the same way as on Sunday. In this case, as shown in Figure 2 (b), the above day of the week change function temporarily sets the programs for Tuesday and Wednesday to the same program as Sunday for the next week, and then automatically sets the program for this week only in the following week. The same program is set.

First, the setting procedure for performing this day of the week change function will be explained. In this case, the mode switch 2a is switched to the time setting mode. Then, the day of the week change switch 21 is pressed. At this time, as shown in FIG. 4(b), as shown in FIG.
From the display state of the liquid crystal display 12 shown in FIG.
(The display disappears and the day of the week display section 12b such as
All day of the week display area 121] rectangular mark is 2
Flashes at a frequency of Hz. In this state, press the day of the week switch 2c that corresponds to the day of the week you want to change - For example, if you want to change Thursday and Friday, press the day of the week switch 2C5゜2c.
Press 6. As a result, as shown in Figure 4(c), Thursday and Friday (marks disappear and the marks become non-blinking).If you make a mistake in this selection, you can switch the If you press 2C again, the mark for that day of the week will disappear, and if you press the day switch 2c for another day of the week,
The mark for that day of the week lights up. Further, the number of settings is not limited to two, but can be set up to six. Next, select the day of the week on which the program you want to change is set. In this case, press the call switch 2g. At this time, as shown in Figure 4 (d), select the day of the week that you want to change. The leftmost mark appears among the other marks that went out, and it's 2F! Flashes at a period of z. This makes it possible to confirm that the desired program has moved to the selection operation for the set day of the week. Then, by pressing the day switch 2c corresponding to the day of the week on which the desired program is set, the day of the week to be changed is selected. Assuming that the day of the week on which the time setting to be changed is set is Wednesday, the day of the week switch 2c is pressed. At this time, as shown in FIG. 4(e), the mark indicating Wednesday flashes at a cycle of 2 Hz. Then, in order to write this set program into the memory of the microcomputer 6, the 1 second switch 2f, which also serves as a write switch, is pressed. This sets the program for changing the day of the week. At this time,
As shown in FIG. 4(f), the liquid crystal display 12 returns to the state showing the current day of the week and time. Then, by returning the mode switch 2a to the normal mode, all day of the week setting operations are completed. Note that even when the mode switch 2a is switched to the normal mode, the mark indicating the current day of the week flashes at a frequency of IHz as shown in FIG. 4(g), indicating that the day of the week has been changed. This is made clear to the user. The switch operation section 2, which inputs the changed day of the week and the specified day of the week in the above-described procedure, constitutes the changed day of the week input means 13 and the specified day of the week input means 14 shown in FIG.

In this embodiment, as shown in FIG. 1, a modified day of the week storage means 15 stores the modified day of the week inputted by the modified day of the week input means 13, and a designated day of the week inputted by the designated day of the week input means 14 is provided. a designated day of the week storage means 16 for storing, and an arithmetic processing means 17 for reading and executing a program for the designated day of the week stored in the designated day of the week storage means 16 on a day that matches the day of the week stored in the changed day of the week storage means 15; and erasing means 18 for erasing the day of the week stored in the changed day of the week storage means 15 on which the program to be changed was executed when the processing of the arithmetic processing means 17 is completed;
The operations from 1 to 18 are performed by the program processing of the microcomputer 6.

The program processing of the micro combinator 6 for changing the day of the week in this embodiment will be described below.

The arithmetic processing means determines whether the next day is the day on which the day of the week is to be changed or not when the time reaches 23:59:59, and at this point, as shown in FIG. The computer 6 calls up the stored changed day of the week,
It is determined whether this changed day of the week matches the next day's day of the week, and if they match, the process moves to changed day of the week processing. In addition, if this change day of the week and the next day of the week do not match,
The program for the next day of the week is called as usual, and this program is executed the next day. When the process shifts to day of the week change processing as described above, the day of the week specified for the day of the week to be executed is read, and the program for this day of the week is read. Then, the next day, a program is executed according to the day of the week to be changed, and when the execution of this program is finished, the original day of the week is called in, and the day of the week changing operation is completed. That is, at this point, the day of the week changing operation is canceled, and from the week after next, the same program as this week will be executed, and there is no need to newly set the original program.

Therefore, this embodiment is extremely effective when temporarily changing program settings.

The setting procedure for canceling this day of the week change will be explained with reference to FIG. In this case, switch the mode switch 2a to the time setting mode and press the day of the week change switch 21 in the same way as the day of the week change setting described above.At this time, press the previously set call switch 2g for changing the day of the week to change the setting. The display shown in FIG. 7(b), which is similar to FIG. 4(e) and shows the case where the day of the week switch 2C to which the program is set is pressed, is displayed on the liquid crystal display 12. In this state, by pressing the erase switch 2j, the day of the week change program is erased. At this time, the display on the liquid crystal display section 1 returns to displaying the current day of the week and time, and the blinking of the mark indicating day 11 also stops, as shown in FIG. 7(c). Then, by switching the mode switch 2a to the normal mode, the operation for canceling the day of the week change is completed. Furthermore, in the fabrication of canceling the day of the week change, by omitting the operation of pressing the erase switch 2j, the changed day of the week can be confirmed from the display on the liquid crystal display 12 shown in FIG. 8(a).

Note that even if the program is set to run on a daily basis, it is also possible to change only a specific day of the week.

Finally, external interrupt control will be explained according to FIGS. 14 and 15. This external interrupt control is performed using manual switch 2.
This is possible only when b is set to automatic, and takes precedence over the program set as described above. Furthermore, this external interrupt control is performed as follows by setting the interrupt operation switch 2 of the operation setting switch mentioned above to 2.

FIG. 14 shows a case where the interrupt operation switch 2 is turned on, and in this case, when an H level signal is input to the interrupt input terminal 11, the control equipment is activated. On the other hand, the fjS15 diagram shows the case where the interrupt operation switch 2 is set to 2 off, and when an H level signal is input to the interrupt input terminal 11, the operation of the control equipment is stopped. . In addition, in the event of a power outage, external interrupt control 8! The function is stopped F:,.

[Effects of the Invention 1] As described above, the present invention is a time switch that has a built-in microcomputer and controls on/off of control equipment according to multiple programs for each day of the week. It becomes necessary to change the program,
When the program to be changed is set to another day of the week, a change day of the week input means for inputting the day of the week on which the program is to be changed, and a change day of the week storage means for storing the change day of the week input by the change day of the week input means. a specified day of the week input means for inputting the day of the week on which the program to be changed is set; a specified day of the week storage means for storing the day of the week input by the specified day of the week input means; and a specified day of the week storage means for storing the day of the week input by the specified day of the week input means. On a day that matches a certain day of the week, it's strange! arithmetic processing means for reading and executing the program for the day of the week on which the desired program is set; and erasing for erasing the day of the week stored in the changed day of the week storage means on which the program to be changed was executed when the processing of the arithmetic processing means is completed; Since the arithmetic processing means can read and execute the program for the specified day of the week stored in the specified day storage means on the changed day of the week stored in the changed day of the week storage means, the changed day of the week and the specified day of the week can be The program can be easily changed by simply inputting the specified day of the week using the input means, and when the program is executed, the erasing means erases the changed day of the week stored in the changed day of the week storage means. The original program can be executed the next week, which is effective for temporary program changes.
