Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electronic time switch that has a built-in microcomputer and is capable of setting a schedule for each day of the week.

[Background Art] As a time switch, there is a time switch that has a built-in microcomputer and is capable of setting a schedule to turn on and off a control device according to a plurality of programs such as for each day of the week.

With conventional electronic time switches, when setting the program as shown in Figure 16a (hereinafter referred to as daily setting) for two or more days (continuously), the program setting as shown in Figures 8b to 8e is within one day. We have adopted a method of concatenating the program settings of 1.
It was cumbersome to have to enter multiple program settings for each program.
Further, in this case, there was also the problem that a large amount of set capacity was required.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and its purpose is to facilitate day-to-day setting and eliminate the need to increase the set capacity even if day-to-day setting is made. The purpose is to provide a time switch.

[Disclosure of the Invention] (Structure) The present invention is a time switch that has a built-in microcomputer and controls on/off of a control device according to a plurality of programs such as for each day of the week. A day of the week setting means for setting the day of the week, a time setting means for setting the on/off time of the control equipment, and a set day of the week detection for detecting that the on/off days of the control equipment set by the day of the week setting means are different. and a set time for detecting that the on and off days of the control device set by the day of the week setting means are the same and the on set time set by the time setting means is later than the off set time. a detection means; and an arithmetic processing means that determines that the program has been running for two days or more when a detection output from either of the two detection means occurs and continuously executes the program for two days or more. By having both of the above-mentioned detection means, it is possible to determine by the time switch itself whether the set program is for one day or less, or whether it is a daily setting. It is possible to perform programs within one day with similar settings. Furthermore, since the time switch itself can recognize that the daily setting is set, it becomes possible to store programs for the daily setting in the same way as programs for within one day, thereby reducing the storage capacity of the program.

(Embodiment) An embodiment of the present invention is shown in FIGS. 1 to 15. The time switch of this embodiment has a built-in microcomputer and can be installed in a DIN72 panel size power distribution board or control board. FIG. 4 shows the functional blocks of this time switch. The switch operation unit 2 is used to set time, program settings, output switching, etc.
By operating the switch operation section 2, the microcomputer 6 performs arithmetic processing as appropriate. Incidentally, the time switch of this embodiment is configured to control the control equipment by the external interrupt input section 4 in accordance with an external input signal input from an external device such as a sensor, regardless of the program set by the switch operation section 2. It is now possible to control the on/off state. The display unit 1 displays the current time, program setting time, output status, etc. using the output from the microcomputer 6. The power supply section 3 is
It converts the free voltage input of AC80V to 240V to DC5V to supply power to the microcomputer 6 and other circuits, and is designed to compensate for power outages using batteries. The output section 5 includes a relay driven by an output signal from the microcomputer 6, and the two circuits can be controlled by independent programs using the relay contact output.

The specific structure of the time switch of this embodiment will be explained with reference to FIG. The casing 7 of the time switch of this embodiment is DIN72 as described above.
It is formed into a rectangular box shape that can be installed on a panel-sized power distribution board or control board.The front part is equipped with the display part 1 and the switch operation part 2, and the upper and lower sides are equipped with power lines and input terminals. A terminal portion 8 for connecting an output line is formed. The display section 1 is composed of a liquid crystal display 12, which includes a time display section 12a that numerically displays the current time and program setting time, ie, "hours,""minutes," and "seconds," and a rectangular mark that indicates the day of the week. A display section 12b, an output display section 12c for displaying the output status, etc. can be displayed. The switch operation section 2 is arranged above the liquid crystal display section 12, and has a normal mode in which the current time or an appropriate display for normal use is displayed on the liquid crystal display 12, a time setting mode in which the time is set, and a setting mode in which the program is set. mode switch 2a for switching, manual switches 2b ₁ and 2b ₂ provided for each circuit to select whether the control equipment is to be controlled by a program by the microcomputer 6 or manually, and a liquid crystal display. Day switches 2c ₁ to 2c ₇ are arranged in a horizontal line below 12 and select each day of the week, an "hour" setting switch 2d that sets the "hour" when setting the time, and a "minute" switch that sets the "minute". Setting switch 2e, set "seconds""seconds"
Setting switch 2f, change the day of the week (details will be explained later)
A call switch 2g that calls the day of the week on which the program to be changed is set when changing the program, an interval switch 2h that repeatedly sets the same time schedule, a day change switch 2i that selects to change the day of the week, and a day of the week change program and an erase switch 2j for erasing. The "second" setting switch 2f also serves as a write switch used when changing the day of the week. The power supply unit 3, interrupt input unit 4, and output unit 5 are housed in a casing 7, and the power supply input terminal 9 of the power supply unit 3 and the output terminals 10 ₁ to 10 ₃ of one circuit of the output unit 5 are connected to the lower terminals. The external input terminal 11 of the interrupt input section 4 and the output terminals 10 ₄ to 10 ₆ of another circuit of the output section 5 are provided on the upper terminal section 8 . Note _that the terminal arrangement _of the output terminals 10 ₁ to 10 ₆ in this embodiment _is as shown in _FIG . , 10 ₃ , 10 ₆ are
It is an NC terminal. The above switch operation part 2
is the switch 2 installed on the front of the casing 7.
In addition to a to 2j, an operation setting switch is provided on one side of the casing 7. This operation setting switch is composed of four switches _2k1 to _2k4 , including a power failure compensation function selection switch _2k1 for selecting whether or not the time switch has a power failure compensation function, and an external interrupt input. An interrupt function selection switch 2k ₂ (in addition,
The operation of this interrupt function selection switch _2k2 will be described later), and two setting changeover switches _2k3 , 2 that switch the operation of each circuit by the output section 5.
It consists of k ₄ . Note that the microcomputer 6 can be reset by turning off the power failure compensation function selection switch _2k1 . The operation of the output section 5 includes a timer operation that sets the on/off time of the control device, and a pulse operation that repeatedly turns the control device on and off and performs this cycle operation for a certain period of time. 2k ₃ ,2
Either action can be selected with _k4 . In the following explanation, a case will be explained in which the time switch is operated as a timer.

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 12a of the liquid crystal display 12 indicates "seconds".
The "hour" display section 12 is fixed except for the display section 12f.
d. Turn the "hour" and "minute" setting switches 2d and 2 until the "minute" display section 12e shows the desired "hour" and "minute", respectively.
Set by pressing e multiple times to advance the numerical value. "Seconds" setting switch 2j is designed to start displaying "seconds" from 0 seconds the moment it is pressed and released, and "seconds" can be set by pressing and releasing it after setting "hours" and "minutes". do. If you also need to change the day of the week, press day switch 2.
The day of the week can be changed using c ₁ to 2 _{c 7} . Then, by switching the mode switch 2a to the normal mode, the current time setting operation is completed.

Next, the program settings for turning on and off the control equipment will be explained. In this case, the setting changeover switches 2k ₃ and 2k ₄ must 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" on the time display section 12a, where the current time on the liquid crystal display 12 was displayed,
The "minute" display sections 12d and 12e become "-:--" as shown in FIG. 7a, and the "ON" symbol is displayed on the output display section 12c to the left of this display. Note that in normal mode, this output display section 1
The "ON" displayed in 2c indicates that the control device is in the on state, and when in the setting mode, this "ON" display indicates that the time to be entered is the time to turn on the control device. It is a display. In addition, the "seconds" display 2f of the time display is 1 to 16.
The numerical value will be displayed. This 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,
The time at which the control equipment is turned on is set using the "hour" and "minute" setting switches 2d and 2e in the same manner as in the case of time adjustment described above. The day of the week is set using the day of the week switches 2c ₁ to 2c _7. For example, if you want to turn on and off the control equipment at the above times from Monday to Friday, set the appropriate day of the week switch 2c ₁ to 2c ₇ . Press 2c. This day of the week switch 2
When c is pressed, the day of the week display section 12b is displayed. FIG. 7b shows the display state of the liquid crystal display 12 with the ON time of the control equipment set in this manner. Microcomputer 6 at this on-set time
Reading is performed by pressing 2f of the "second" setting switch which also serves as the write switch. When this "second" setting switch 2f is pressed, the "hour" and "minute" displays 2d and 2e on the liquid crystal display 12 automatically change to "--:--" as shown in Fig. 7d. , the "ON" display on the output display section 12c on the left side of this display changes to "OFF" display. In the case of this embodiment, the ON and OFF times of the control equipment are set as a set, and the microcomputer 6 cannot accept settings of only the ON time and OFF time unless they are set as a set. It's becoming like that. 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, when no programs are programmed, the remaining number of settings is 16, and each time one program is set, the remaining number of settings decreases by 2.
By checking the remaining number of settings, the user can confirm whether the program settings have been made with certainty. When this program setting is completed, the display on the liquid crystal display 12 becomes the initial state at the time of setting the on time, as shown in FIG. 7e, and the on/off time of the control equipment can be further set. This program ends 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 FIG. In other words,
In microcomputer 6, mode switch 2a
Since it has been switched to the setting mode, the operation shifts to displaying the remaining number of settings, and if there are remaining settings, the series of operations described above is executed,
When there is no remaining number of settings, "0" is displayed as the remaining number of settings, and the operation is terminated so that no input signal from the switch operation section 2 is accepted.
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.

The above explanation was about the same operation as the one-day program setting of a normal electronic time switch.
It is now possible to set up a day trip that spans more than one day. 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 time of the control equipment, it is possible to set the program for different days of the week, thereby allowing day-to-day settings. In other words,
In this embodiment, as shown in FIG. 1, a set day of the week detection means 15 for detecting that the on and off days of the control equipment set by the day of the week switch 2c as the day of the week setting means 13 are different; "Hour", "minute", "second" setting switches 2d, 2e, 2 whose on and off days of the control equipment set by the switch 2c are the same and which serve as the time setting means 14
Set time detection means 16 for detecting that the on set time set in f is later than the off set time
When a detection output from either one of the detection means 15 and 16 is generated, it is determined that the program has been set for two days or more, that is, it is a daily setting, and the program is continuously executed for two or more days. It is also equipped with arithmetic processing means 17 that performs day-crossing operations. In addition,
The set day of the week detection means 15 and the set time detection means 1
6 and the operation of the arithmetic processing means 17 are performed by software of the microcomputer 6. For example, as shown in Figure 3, from 12:00 on Monday to Thursday
When operating control equipment all day long until 12:00,
When setting the day of the week for the ON setting time of the control device, Monday and the time are set, and when setting the OFF setting time, Thursday and the time are set. In this case, since the days of the week are different, the day-of-the-week detection means 15 of the microcomputer 6 detects that it is a day-to-day setting, so the day-to-day setting is automatically performed. Furthermore, even if the ON set time is later than the OFF set time on the same day of the week, the set time detection means 16 of the microcomputer 6 detects that the day-to-day setting is set, so the day-to-day setting is automatically performed. . For example, from 8:00 PM on Monday to the following Monday.
If the daily setting is performed for about a week until 6:00 AM, the on and off days of the week are the same, but the on setting time is later than the off setting time. In such a case, the present embodiment is provided with a set time detection means 16, so that even if the control equipment is turned on and off on the same day of the week, it is possible to detect whether the on set time is later than the off set time. It is also possible to detect the day-to-day setting for approximately one week as described above, and the day-to-day setting is automatically performed. Incidentally, a flowchart showing a determination processing program by the microcomputer 6 for the above-mentioned daily crossing setting is shown in FIG. 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.
Note that it is impossible for the on and off setting times to be the same on the same day of the week, so in this case, the microcomputer 6 handles the error.

Furthermore, this embodiment is provided with a day-of-the-week changing function, which will be described below. For example, as shown in Figure 9a, 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 the schedule has been set. Suppose that next week's Tuesday and Wednesday are national holidays and the control equipment should be operated in the same way as Sunday. In this case, using the day of the week change function mentioned above, the program for Tuesday and Wednesday will be temporarily set to the same program as Sunday for the next week, and then the next week will automatically have the same time settings as this week. It is.

First, the setting procedure for performing this day of the week change function will be explained. In this case, mode switch 2a
Switch to time adjustment mode. Then, press the day of the week change switch 2i. At this time, Fig. 10b
As shown in FIG.
The displays except 2b disappear, and all the rectangular marks serving as the day of the week display section 12b blink at a frequency of 2Hz. In this state, press the day switch 2c that corresponds to the day of the week you wish to change. For example, to change Thursday and Friday, use the day switch 2c ₅ ,
Press 2c ₆ . As a result, as shown in FIG. 10c, the marks except Thursday and Friday disappear, and the marks become non-blinking. If you make a mistake in this selection, switch the day switch 2c for the incorrect day of the week.
If the button is pressed again, the mark for that day of the week disappears, and if the day switch 2c for any other day of the week is pressed, the mark for that day 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 call switch 2g. At this time, as shown in Figure 10d,
The leftmost mark among the extinguished marks for the day of the week other than the day you want to change appears and blinks at a frequency of 2 Hz. 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 of the week 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 you wish to change is set is Wednesday, press day switch _2c4 . At this time, as shown in FIG. 10e, the mark indicating Wednesday flashes at a frequency of 2 Hz. Then, in order to write this set program into the memory of the microcomputer 6, the "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, the first
As shown in FIG. 0 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 set to the normal mode, the mark indicating the current day of the week flashes at a frequency of 1 Hz, as shown in Figure 10g, to notify the user that the day of the week has been changed. It is made so that you can understand.

Next, the program processing of the microcomputer 6 for changing the day of the week in this embodiment will be explained.
A determination as to whether the next day is the day on which the day of the week is to be changed is made when the time reaches 23:59:59. At this point, as shown in FIG. 11, the microcomputer 6 calls up the stored changed day of the week, determines whether this changed day of the week matches the next day's day of the week, and if so, performs the changed day of the week process. Transition. Note that if this changed 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, the program is executed according to the changed day of the week, and when the execution of this program is finished, the original day of the week is called,
End the day of the week change operation. 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 is explained in the first step.
This will be explained according to Figure 2. In this case, set mode switch 2 in the same way as the day of the week change setting described above.
Switch a to time setting mode and press day of the week change switch 2i. At this time, a display as shown in FIG. 12b, which is similar to FIG. will be displayed. In this state, by pressing the erase switch 2j, the day of the week change program is erased. At this time, the liquid crystal display part 1
As shown in FIG. 12c, the display returns to displaying the current day of the week and time, and the mark indicating the day of the week also stops blinking. And mode switch 2
By switching a to the normal mode, the operation to cancel the day of the week change is completed. Furthermore, by omitting the operation of pressing the erase switch 2j in the operation of canceling the day of the week change, the changed day of the week can be confirmed from the display on the liquid crystal display 12 shown in FIG. 13a. 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 with reference to FIGS. 14 and 15. This external interrupt control is
This is possible only when the manual switch 2b is set to automatic, and is performed in priority to the program set as described above. Furthermore, this external interrupt control is performed as follows by setting the interrupt operation switch _2k2 of the operation setting switch mentioned above.
Figure 14 shows a case where the interrupt operation switch _2k2 is turned on. In this case, when an H level signal is input to the interrupt input terminal 11, the control equipment is activated, and the opposite is activated. FIG. 15 shows a case where the interrupt operation switch _2k2 is set to OFF, and when an H level signal is input to the interrupt input terminal 11, the operation of the control equipment is stopped. Note that in the event of a power outage, the external interrupt control function will stop.

[Effects of the Invention] As described above, the present invention is a time switch that has a built-in microcomputer and controls on/off of a control device according to a plurality of programs such as for each day of the week. a day of the week setting means for setting the day of the week; a time setting means for setting the on/off time of the control equipment; and a set day of the week for detecting that the days of the week for the on/off of the control equipment set by the day of the week setting means are different. A setting for detecting that the on and off days of the control device set by the detection means and the day of the week setting means are the same, and the on setting time set by the time setting means is later than the off setting time. a time detection means; and an arithmetic processing means that determines that the program has been running for two days or more when a detection output from either of the two detection means occurs and continuously executes the program for two or more days. By having both of the above-mentioned detection means, the time switch itself can determine whether the set program is for one day or less, or whether it is a daily setting. It is possible to use the same settings as programs for one day or less, making it easy to set daily settings, and because the time switch itself can recognize that it is a daily setting, programs with daily settings can also be set for more than one day. It has the advantage that it can be stored in the same way as a program, and there is no need to increase the setting capacity.
