Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic time switch for controlling the operation of a load according to a preset operation date / time and operation state program of the load.

[0002]

2. Description of the Related Art An electronic time switch of this type is used, for example, for the purpose of controlling the operation of a chime for informing the start or end of work at school. When used for such a purpose, the time schedule for ringing the chime, which is a load, is the same every day from Monday to Friday, and is usually different on Saturday and Sunday. Also, different time schedules are required on public holidays, Saturdays on holidays that are biweekly, and days with special events.

Therefore, in the electronic time switch configured so that the date and time when the load is operated can be specified, the time schedule is managed as a repetitive pattern on a weekly basis, and a day having a special event (hereinafter,
The program can be efficiently set by separately setting the time schedule only on the "specific day". Based on this way of thinking, 1 for a specific day
The following method is conceivable as a method of allocating the time schedule of the day (hereinafter referred to as "daily pattern").

A method of selecting and setting from a plurality of daily patterns registered in advance. How to set a daily pattern for each specific day. How to transfer daily patterns from other days.

[0005]

In the method described above, it is possible to flexibly cope with the time schedule of a specific day by registering a large number of daily patterns. However, it is usual to give a code (name or number) to the registered daily pattern, and since the code is specified for the selection of the daily pattern, the daily pattern of each code becomes the daily pattern of which day. It is difficult to understand the relationship of correspondence. Therefore, when setting up the program,
Since it is necessary to create a table as to which code to select for each day, there is a problem that the setting work of the program is troublesome. Further, since the daily pattern to be registered must be created individually, there is a problem that it takes time to register the daily pattern.

According to the above-mentioned method, since the daily pattern is individually created only on the specific day, the time schedule of the specific day can be flexibly dealt with. However, since an independent daily pattern is created for a specific day, it is necessary to create all daily patterns even when only a part of the daily pattern is different. Therefore, if the load is operated many times in a day, there is a problem that it takes time to set the daily pattern.

On the other hand, in the above-mentioned method, since the daily pattern of another day is diverted, the setting is easy. However, if a desired daily pattern does not exist in the registered daily patterns, there is a problem that it cannot be dealt with. That is, there is a problem that the time schedule on a specific day cannot be flexibly dealt with.

The present invention is intended to solve the above problems, and is capable of flexibly responding to a time schedule of a specific day, and by using a common part with the time schedule of another day. It is intended to provide an electronic time switch that can be set in a short time.

[0009]

According to the present invention, there are provided a program setting means for setting a program in which a load control date and time and a load control state at each date and time are set, a storage means for storing a plurality of programs, and An electronic system equipped with a clock means for counting the date and time of the current day and a current day of the week, and a control means for controlling the load according to the program when the current date and time matches the date and time of any program stored in the storage means. The time switch has a common configuration.

In order to achieve the above-mentioned object, the program setting means can allocate a time schedule for the time at which the load is controlled in units of one day, each day of the week and one day of the week. Eight or more day designation parts corresponding to the above specific days, a date designation part that designates the day to control the load by year / month / day, and a day to control the load at the same time with respect to the designated time. By selecting one of the day designation parts for the days specified in the date designation part and the schedule assignment part that assigns the time schedule of one day to each day designation part by collectively specifying by the day designation part and the specific date setting unit that can set a time schedule that was assigned to the selected day of the week specifying unit as a time schedule of the day specified by the date specified part, priority It started as a program date and time and end date
A priority program that specifies when and when to turn the load on and off
And a ram setting unit, the control means, your priority program
The period between the start date and time and the end date and time
Control the load in the state specified in
During the period other than the start date and time and the end date and time, the load is controlled based on the time schedule assigned by the day of the week designation section on the days specified by the specific day setting section, and calculated by the clocking means on other days. The load is controlled by the time schedule assigned to the day-of-the-week designation section corresponding to the day of the week.

According to the second aspect of the present invention, the date designating section has a negative sign.
A function to specify the day to control the load as month / day is added,
The control means controls the load for a designated day only when the date and time for controlling the load in the program stored in the storage means includes a year, and the date for controlling the load in the program stored in the storage means for the year. When not included, the load is controlled on the same day each year.

According to a third aspect of the present invention, there is provided display means for displaying the date and time for controlling the load when setting the program,
The program setting means includes a date and time specifying section for specifying the date and time by sequentially increasing and decreasing the date and time displayed on the display means, and an initial value setting section for displaying the initial value of the date and time on the display means when the date and time is not set. And the initial value setting section
The current year obtained by the timekeeping means is used as the initial value of the year.

[0013] In the present invention of claim 4, the program setting unit is provided with a final day correcting unit for correcting the value of the day to the last day of the month when the value of the day of the specified date and time exceeds the last day of the month Is there.

[0014]

According to the structure of claim 1, every day of the week and 1
Equipped with eight or more day designation parts corresponding to specific days more than one day, the day to control the load at the same time is collectively specified by the day designation part. Since the time schedules that control the load are assigned respectively, if you set one time, you can specify the day of the week to control the load at that time with the simple operation of specifying the day of the week. You can set the schedule. This means that when time schedules for each day of the week have a common part, the labor of time-consuming time inputting work can be significantly reduced as compared with the case of inputting the time for each day. In addition, since the day of the week designation section has one or more items corresponding to a specific day different from the day of the week, a time schedule different from the normal day time schedule is set in the specific day on the specific day. Therefore, it is possible to flexibly deal with the case where a time schedule different from usual is set. Furthermore, the load is controlled based on the time schedule assigned by the day of the week designation section on the days specified by the specific day setting section, and on other days the time schedule assigned to the day of the week specified section corresponding to the day of the week obtained by the timekeeping means. Since the load is controlled by, the time schedule only needs to be changed for a specific designated day, and the time schedules for other days are automatically set based on the day of the week. Moreover, since the day to control the load can be specified by year, month, and day, it is possible to set the program for a long period of time within the range of the capacity of the storage means. There is an advantage that maintenance is unnecessary for a long period of time. In addition, it is allocated by the specific day setting section and the day of the week specification section
The priority program that controls the load in priority to the time schedule
Since the program can be set, the specific day setting section and the day of the week
If the time schedule cannot be handled by the day designation department
Even in the case of
It will be possible. Start date and time of load control in priority program
And the end date and time are specified, it is continuous for a relatively long period of time.
It can also handle various load controls.

According to the structure of claim 2, the date for controlling the load is specified by one of year / month / day and month / day, and the date and time for controlling the load in the program stored in the storage means is set. When the year is included, the load is controlled only for the designated one day, and when the date of controlling the load in the program stored in the storage means does not include the year, the load is controlled on the same day every year. If the year is not specified, the same operation can be repeated every year, and the load can be controlled for a long time without increasing the capacity of the storage means.

According to the configuration of claim 3 , since the current year obtained by the timekeeping means is displayed as the initial value of the year on the display means when the date and time is not set, the latest year is set regardless of the year at the time of factory shipment. The year of can be displayed. This is
When setting the date and time, an initial value close to the year to be set can be given, which leads to a reduction in the time and date setting work.

According to the structure of claim 4 , when the day value of the designated date and time exceeds the last day of the month, the day value is corrected to the last day of the month. Therefore, an impossible date is set. Is prevented.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The electronic time switch of this embodiment is provided with a program setting means 1 as shown in FIG. 1, and sets a program which is a set of a date and time when a load is controlled and a load control state at that date and time. To do. The set program is stored in the storage means 2 together with the program number for each program. A plurality of programs can be stored in the storage means 2. On the other hand, the time counting means 3 measures the current date and time and obtains the current day of the week, and when the date and time of the program stored in the storage means 2 matches the current date and time, the control means 4 causes the output means 5 to operate. Control the load. That is, the output means 5 includes a switch element formed of a latching relay inserted between the power source and the load,
The on / off control of the switch element controls the energization state of the load. Here, by using the latching relay, the energization time to the relay is shortened, which leads to suppression of power consumption. The display means 6 is connected to the control means 4 so that the display means 6 can display the current date and time measured by the time measurement means 3 and the program stored in the storage means 2.

The program setting means 1 is capable of allocating a time schedule for the time at which the load is controlled on a day-by-day basis, and eight or more day-of-week designation sections corresponding to each day of the week and one or more specific days. 11 and a schedule allocating unit 12 that allocates a time schedule for one day to each day of the week designating unit 11 by collectively designating the days for controlling the load at the same time by the designated time of day. A specific day setting unit 13 that can set the time schedule assigned to the selected day specifying unit 11 as a time schedule of the specified day by selecting one of the day specifying units 11 for the specified days. . The control means 4 controls the load on the day designated by the specific day setting section 13 based on the time schedule assigned by the day of the week designation section 11, and on the other days, designates the day of the week corresponding to the day of the week obtained by the time counting means 3. The load is controlled by the time schedule assigned to each department. Further, the program setting means 1 includes a date designating section 14 for designating a day for controlling the load by one of year / month / day and month / day, and a time designating section 15 for designating a time for controlling the load. The date and time designation unit 16 is provided. The date / time designation unit 16 designates the date / time by sequentially increasing / decreasing the date / time displayed on the display unit 6. When the date and time has not been set, the initial value given by the initial value setting section 17 is displayed on the display means 6. The initial value setting unit 17 uses the current year obtained by the clock means 3 as the initial value of the year. In addition, the control unit 4 specifies 1 when the date and time for controlling the load in the program stored in the storage unit 2 includes a year.
The load is controlled only for one day, and when the date for controlling the load in the program stored in the storage means 2 does not include the year, the load is controlled on the same day every year. Further, the program setting means 1 is provided with a final day correction unit 18 which corrects the day value when the day value at the designated date and time exceeds the last day of the month.

On the other hand, as shown in FIG.
At the center of the front surface of the device, there is provided a display unit 21 which is a display unit 6 and an operation unit 22 which is a part of the program setting unit 1. Further, a plurality of terminals 23 for connecting the switch elements of the output means 5 to the power supply line and the load line are arranged in rows along the upper and lower edges of the front surface of the housing 20. On the front of the housing 20,
Energization display lamps L _{1 to} L ₃ for indicating energization are also provided. The present embodiment corresponds to a power source and a load of two circuits,

A display, a fluorescent display tube, a plasma display, etc. can be used. On the screen of the display unit 21, a date display area D ₁ that displays the date in year, month, day, a time display area D ₂ that displays the time in hours, minutes, and seconds, each day from Sunday to Saturday, and two specific days. Symbols corresponding to and (S1, S2, Mo, Tu, We, Th,
Fr, Sa, Su) is provided for day of the week display area D ₃ . Further, it is possible to indicate which circuit, out of the two circuits of the power source and the load, is to be controlled by a number, and also indicate the on / off state of the load by characters. On the front surface of the housing 20, a plurality of symbols SY corresponding to the operation modes described later are written along the upper edge of the display 21, and the triangular cursor C displayed on the display 21 indicates which of the symbols. The current operation mode is indicated by moving to the position corresponding to SY. Further, the portion showing seconds in the time display area D ₂ is also used as an area for displaying a program number described later.

The operation unit 22 has a total of nine day-of-the-week designating switches S _{1 to} S ₉ (corresponding to the day-of-week designating unit) corresponding to each day of the week from Sunday to Monday and two specific days, and an operation described later. Used for mode switch S ₁₁ to select a mode, 6 date / time designation switches S _{12 to} S ₁₇ (corresponding to the date / time designation unit) corresponding to year / month / day / hour / minute / second, and to call a program. A call switch S ₁₈ and two manual operation switches SW ₁ and SW ₂ for selecting a state in which the load is operated according to a set program and a state in which the load is turned on / off regardless of the program are provided. The manual operation switches SW ₁ and SW ₂ correspond to the power supply circuit and the load circuit. Manual operation switch SW ₁ , SW ₂
A slide switch is used for the manual operation switch SW ₁ ,
Pushbutton switches are used in addition to SW ₂ .

To specify the operation mode, press the mode switch S ₁₁ . Each time the mode switch S ₁₁ is pressed, the cursor C moves to a position corresponding to the symbol SY representing the operation mode, and the cursor C blinks, whereby the operation mode currently specified can be known. As the operation mode, a “load control operation mode” (left end) for controlling the load L according to a program, the time measuring means 3

The "weekly program setting mode" is an operation mode for setting a time schedule (daily pattern) for each day of the week, and sets a timer operation program and a pulse operation program. In addition, in the "weekly program setting mode", in addition to the daily patterns for seven days in a week, the daily patterns for two days can be additionally set, so that a total of nine daily patterns can be set. It has become. Therefore, in the "weekly program setting mode", a daily pattern in which the correspondence between the time of day and on / off of the load is set is set, and each daily pattern is labeled. By the way, in the present invention, the annual time schedule is based on the repetition of the time schedule of a week unit, and is based on the assumption that an exceptional time schedule will occur sporadically. If an exceptional daily pattern can be set for two days in addition to the daily pattern described in, it is considered that the annual daily pattern can be almost covered. Therefore, the label of the daily pattern is set in the form of the day of the week for 7 days and the specific day for 2 days. That is,
Each out pattern is assigned to the day of the week designation switch S ₁ to S _9. Here, when the exceptional daily pattern for two days cannot be dealt with, it is possible to control the load on a one-shot basis by using the priority program.

The "special day setting mode" is an operation mode for assigning a specific day to a daily pattern that occurs exceptionally with respect to the repetition of the time schedule on a weekly basis. That is, one of the daily patterns set in the "weekly program setting mode" is assigned to a specific day when an exceptional daily pattern occurs. Therefore, the date is specified and the daily pattern corresponding to the date is selected. In addition, when specifying the date, there are cases where the date is specified and cases where only the month and day are specified without specifying the year. If you do not specify a year, the same daily pattern repeats on the same day each year. Out pattern of the day that are not specified in the "special day setting mode" is among the out patterns assigned to the day designated switch S ₃ to S _9, is out pattern day corresponding to the day of the week determined by the timing means 3 Used.

The "priority program setting mode" is a mode for setting a priority program. That is, the start date and time, the end date and time, and the load on / off are designated. By setting such a priority program, it is possible to flexibly cope with the case where the daily pattern alone cannot cope. For specifying the start date and time and the end date and time of "Priority program setting mode",
Similar to the “special day setting mode”, there are cases where the date is specified and cases where only the month is specified without the year being specified. If the year is not specified, the load will be controlled at the same date and time each year.

By the way, since the date and time designating switches S _{12 to} S ₁₇ are used to set the date and time, as is apparent from the above description, in the "current time setting mode" and the "priority program setting mode", all Date and time switch S ₁₂
~ S ₁₇ are used, and in the "weekly program setting mode", the hour designation switch S ₁₅ , the minute designation switch S ₁₆ , the second designation switch
₁₆ is used, and in the “special day setting mode”, the year designating switch S ₁₂ , the month designating switch S ₁₃ , and the day designating switch S ₁₄ are used. In an operation mode other than the “current time setting mode”, before operating the date / time specifying switches S _{12 to} S ₁₇ when setting the date / time, the display unit 21 does not display the numerical value, and the position where the numerical value is displayed. A horizontal line is displayed at the end of the line to indicate that it is in the unset state (see FIG. 10A). Then, pressing one of the specified date switch S ₁₂ to S ₁₇ the initial value of the date and time are displayed. In other operating modes except the “current time setting mode”, the date and time specifying the year can be set by pressing the year specification switch S ₁₂ in the unset state, and the year specification switch S ₁₂ can be set in the unset state before the year specification switch S _12. If the month designation switch S ₁₃ or the day designation switch S ₁₄ is pressed, the year is not designated. The initial value is January 1 for month / day / hour / minute / second.
The day is 0 hour, 0 minute, 0 second, and for the year, the value of the current year measured by the time measuring means 3 is used. Thus, by using the current year as the year, the latest year is displayed regardless of the time of shipment. In other words, some conventional products use the year at the time of factory shipment as the initial value, but compared to such products, the difference between the date and time to be set and the initial value is smaller, and the time required for setting is shortened. You can do it. In the "current time setting mode", there is no unset state, and the date and time measured by the time measuring means 3 is displayed.

Each time the year designation switch S ₁₂ is pressed, the year value displayed on the display 21 is incremented,
Year designation switch S with the maximum settable year displayed
Press ₁₂ to display the minimum year that can be set. Similarly, the month designating switch S ₁₃ , the day designating switch S ₁₄ , the hour designating switch S ₁₅ , the minute designating switch S ₁₆ , and the second designating switch S ₁₇ are
Each time it is pressed once, the display value of the corresponding portion of the display 21 is incremented, and the minimum value is displayed next to the maximum value. Here, the maximum value of the date designating switch S ₁₄ automatically changes depending on the year and month. That is, if the year specifying switch S ₁₂ or the month specifying switch S ₁₃ is operated after the day is set to 29 to 31 by the day specifying switch S ₁₄ , the date is adjusted to the last day of the month as necessary. Is changed. For example, “February 29, 1992”
If you change the year to 1993 after setting
Changed to "February 28, 1993". The maximum value of the hour designating switch S ₁₅ is “23”. If the year is not specified, February 29 cannot be set. If you specify the year, the day of the week will automatically change according to the day. The date and time designating switches S _{12 to} S ₁₇ are set for a predetermined time (for example, 1
The display by continuously pressing sec) or more can be continuously changed, while the display is continuously changed day is not displayed, when the release the specified date switch S ₁₂ to S ₁₇ The day of the week is displayed. The designated date and time is registered by pressing the mode switch S ₁₁ .

The above-described operations relating to the date and time are summarized as shown in FIGS. That is, it is determined whether or not the year designating switch S ₁₁ or the month designating switch S ₁₃ is pressed (step S1), and if it is pressed, it is determined whether the day is 29 or more (step S2). Two days
If it is 9 or more, the last day correction routine is started (step S3), and if the day is less than 29, the year and month are incremented (step S4). Next, it is determined whether or not the year / month value exceeds the maximum value (step S5), and if it exceeds the maximum value, the year / month value is returned to the minimum value (step S6), and the process proceeds to the next step. If the year / month value is less than or equal to the maximum value, the next process is performed. Next, it is determined whether or not the date designating switch S ₁₄ has been pressed (step S7), and if it has been pressed, the date setting routine is started (step S8). If pushed the day designated switch S _14, to determine whether the mode switch S ₁₁ is depressed (step S9), and the mode switch S ₁₁ is completed the specified if pressed date. If the mode switch S ₁₁ is not pressed, the process returns to step S1. The last day correction routine corrects the last day of the month according to the year and month. As shown in FIG. 7, it is determined whether the month is February (step S11), and if February is leap year. It is determined whether or not (step S12). If it is a leap year, it is set to 29th (step S13), and if it is not a leap year, it is corrected to 28th (step S14). If it is not February, it is determined whether it is April, June, September, or November (step S15), and if the day is 31st (step S16), it is corrected on 30th. Yes (step S17). In the day setting routine, as shown in FIG. 8, the last day is determined by year and month in the same manner as the last day correction routine (steps S21 to S27), and the last day of the month is set. After that, the day value is incremented (step S28), and it is determined whether or not the last day is exceeded (step S29). If the final date is exceeded, the day value is reset to 1 (step S30).

The operation of each operation mode will be specifically described below. First, in the “current time setting mode”, as shown in FIG.
As shown in (a), the cursor C moves to the second symbol from the left among the symbols SY representing the operation mode, and blinking is displayed. The current date and time is designated by the date and time designation switches S _{12 to} S ₁₇ , as described above. The operation method of the date / time designation switches S _{12 to} S ₁₇ is also as described above. However, the initial value including the year is displayed on the display 21 regardless of which of the date / time designation switches S _{12 to} S ₁₇ is pressed from the state before the setting shown in FIG. 9A. By setting the current date and time in this way, the current time can be set as shown in FIG. 9B (here, April 2, 1991).
5 (Thursday) 11:58:00 seconds is displayed).

Next, the "weekly program setting mode" and the "special day setting mode" will be described with reference to specific examples. Here, the setting of the time schedule that sounds the chime that notifies the start and end of work at school is shown as an example, and in order to measure physical fitness on Wednesday, April 15, 1992, the time schedule after the third period is set. , Shall be changed for normal Wednesday time schedule. That is, the usual daily pattern for one week (time schedule for one day) is set as shown in the left column of Table 1, and the daily pattern for the above-mentioned specific day (April 15, 1992) is shown in the right column of Table 1. Shall be set as follows.

[0033]

[Table 1]

In Table 1, Saturday does not have the 5th and 6th periods, and it is not necessary to ring the chime on Sunday. Here, it can be seen that the specific day can be set up to the second time period in the same manner as on normal Wednesday, so that it is necessary to change only the time schedule after the third time period. The program corresponding to the daily pattern as shown in Table 1 is set in the "weekly program setting mode", in which the chime is required to ring for a fixed time at the start and end of each time period. , Set the pulse operation program with each time in the above table as the ON time. In the “weekly program setting mode”, since it is not necessary to specify the date, the hour designating switch S ₁₄ , the minute designating switch S ₁₅ , and the second designating switch S ₁₆ are used to set the on time and the on period (off if the program is a timer operation program). You may set the time)
To set. That is, first, the mode switch S ₁₁ is pressed several times to select the “weekly program setting mode” (the cursor C is moved to the position corresponding to the third symbol SY from the left). The daily patterns corresponding to the day-of-the-week designating switches S _{1 to} S ₉ are set as shown in Table 2. That is, instead of setting a time schedule for each day of the week and registering a daily pattern, as shown in Table 2, all the times at which the chime sounds are extracted from Table 1, and the chimes sound at each time. Correspond to the day of the week. That is, in the "weekly program setting mode", the on-time and on-period are set by the hour designating switch S ₁₄ , the minute designating switch S ₁₅ , and the second designating switch S ₁₆ , and the day of the week corresponding to the time is set to the day of the week designating switch S. ₁ ~
Specified by S ₉ . After specifying any day of the week corresponding to the time, a mode switch S ₁₁ by pressing once, it can correspond to the day for the next time. Also, after specifying the day of the week for the time, press the mode switch S ₁₁
Press the button twice to switch to the next "special day setting mode". here,
S1 in Table 2 indicates that the daily pattern is registered in the day-of-the-week designating switch S ₁ . That is, the day-of-the-week designating switches S ₁ and S ₂ can be treated in the same manner as the normal day-of-the-week designating switches S _{3 to} S ₉ .

[0035]

[Table 2]

If the correspondence between the time and the day of the week is set by the "weekly program setting mode", it means that the daily pattern of each day of the week is set. Therefore, April 15, 1992
When setting the daily pattern with the day as a specific day,
In the “special day setting mode”, the daily pattern of the specific day S1 may be associated with April 15, 1992. That is, first, by operating the mode switch S ₁₁ ,
As shown in (a), the cursor C is moved to the position corresponding to the fourth symbol SY from the left, and the "special day setting mode" is selected. The cursor C is blink-displayed at this position. At this time, the date is not displayed, but the program number is displayed. The program number will be described later. In this mode, when there is no remaining capacity for storing the program in the storage means 2, the display 21 displays "Full" and the program cannot be set any more.
If the mode switch S ₁₁ is pressed once in the state where “Full” is displayed, the circuit 1 shifts to the next mode. Here, in the figure description, May 25, 1991
A state in which the day (Saturday) is set as the specific day and the daily pattern of the specific day S1 is associated is shown.

[0037] In the "special day setting mode", by manipulating the date and time specified switch S ₁₂ ~S ₁₄ that first corresponding to the year, month, and day, to display the date of the specific date on the display device 21 (FIG. 10 (b )reference). The date setting is as described above. Here, when the year designation switch S ₁₂ is first pressed to designate the year from the unset state shown in FIG. 10A, a specific date including the year is designated as the specific date, and the daily pattern of the load control is specified. Can be a one-time operation on a specific day. Further, when the year is not specified, the load control is performed every year on the same month and day with the same daily pattern. That is, as shown in FIG. 11, it is determined whether or not the year is designated for the date of the specific day (step S31), and if the year is designated, the load is controlled by the daily pattern set only on that date. (Step S32) If the year is not specified, the load is controlled in the same daily pattern on the same day every year (step S33).

Next, the day of the week having the daily pattern to be set on the displayed specific day is selected by operating the day of the week switches S _{1 to} S ₉ . Here, the specific date S1
10 is specified, "Sa" indicating the original day of the week and "S1" indicating the specified specific day are displayed at the same time, as shown in FIG. Further, in order to distinguish the original day of the week and the day of the week on which the daily pattern is set, the latter is displayed as a blink. By pressing the day-of-the-week designating switches S _{1 to} S ₉ different from the day of the week on which the blink is displayed, the newly pressed day of the week is blink-displayed. When the daily pattern has already been set with the same day as the specific day, only the last set daily pattern is valid and the previous daily pattern is deleted. In addition, when the specific day that is set only by the month and day without specifying the year and the specific day that specifies the year are duplicated, the daily pattern of the specific day that specifies the year takes precedence. . However, in this case, daily patterns that do not specify a year are valid for another year.

Thus, after setting the daily pattern for the specific day, if the mode switch S ₁₁ is pressed once,
The program number is incremented as in 0 (d) and the display of the year, month, day and the day of the week is erased. If the year, month, day and the daily pattern are designated by repeating the above-described operation, the daily pattern can be set for a plurality of specific days. When the daily pattern is not designated, all days of the week are blinked and the screen of FIG. 10 (d) is not displayed. In such a state, one of the day designation switches S _{1 to} S ₉
Press to cancel. After setting the daily pattern on the specific day in this way, if the mode switch S ₁₁ is pressed twice, the operation mode shifts to the next operation mode (“priority program setting mode” of the circuit 1) as shown in FIG.

By the way, as described above, when setting a daily pattern on a specific day, a method of designating a year and a method of not designating a year can be selected. When specifying, specify only the month and day without specifying the year, and specify the year as necessary for specific days such as leap years such as spring equinox day and autumn equinox day that change dates. Can be done. As a result, if the capacity of the storage means 2 is within the allowable range, the daily pattern of the specific day can be set for a long period of time, and the schedule can be set even for a long period such as 10 years or more. If decided, it will be possible to eliminate the need for maintenance for setting specific days.

On the other hand, in the case of confirming the program for the set daily pattern of the specific day, the call switch S ₁₈ is pressed to display the program of the desired program number on the display. The call switch S ₁₈ is effective in any condition as long as it is in the “special day setting mode”.
For example, if the call switch S ₁₈ is pressed once from the display state as shown in FIG. 12A, the specific day having the smallest program number is displayed as shown in FIG. 12B.
At this time, the contents being set are temporarily stored in the storage unit 2. When the call switch S ₁₈ is pressed with no program set, the character "End" is displayed on the display 21, as shown in FIG. 12 (c). The program number increases each time the call switch S ₁₈ is pressed, and the character “End” is displayed when the call switch S ₁₈ is pressed with the specific day having the maximum program number displayed.
In this case, if the call switch S ₁₈ is further pressed in the state where the letters “End” are displayed, the specific date having the smallest program number is displayed. Further, when the program is deleted by an operation described later for a specific day having a maximum program number, the program number is skipped and displayed. When the call switch S ₁₈ is kept pressed for a predetermined time (for example, 1 second) or more, the fast-forwarding is performed, and when "End" is displayed in the fast-forwarding, the fast-forwarding is stopped.

When changing the program for the daily pattern on a specific day, the target program may be overwritten while the confirmation is made as described above. That is, the same operation as at the time of setting may be performed in a state where the specific day is called by the call switch S ₁₈ . On the other hand, when erasing a program having a specific program number, the year designating switch S ₁₂ and the day designating switch S ₁₄ are simultaneously pressed.
By this operation, the display state of FIG.
The display state of (b) is entered, and other information is erased, leaving only the program number. That is, no program is registered for the deleted program number.

After the above operation, the mode switch S
_By pressing ₁₁ once, the state before pressing the call switch S ₁₈ is restored. For example, if the setting of the program number (18) on the specific day has been completed in FIG. 12A, the program number (1
Only the program number (19) is displayed on the display 21 so as to prompt the setting of the specific day of 9). Also,
When performing a load control operation as a time switch, if the specific day set in the "special day setting mode" is reached as described above, the day of the daily pattern corresponding to the specific day is blinking displayed. .

As described above, in the "weekly program setting mode", the daily pattern of each day of the week is set by associating all the times when the load is operated with the days of the week (including the specific day) when the load is operated. After setting, the day of the week on which the daily pattern of each specific day is set in the "special day setting mode" may be selected.
That is, the day of the week switch S ₃ for designating a normal day of the week
In addition to ~ S ₉ , two extra day of week switch S ₁ ,
Since S ₂ is provided, if the daily pattern is associated with the day-of-the-week designating switches S ₁ and S ₂ , the daily pattern on the specific day can be easily set. Further, when operating the load at the same time on different days, it is sufficient to operate the day-of-the-week designating switches S _{1 to} S ₉ corresponding to the time in order with the time set, so that the time can be set for each day of the week. Compared with the case of setting, the setting work will be significantly reduced. That is, the program can be set in a short time.

In the "priority program setting mode", FIG.
As shown in FIG. 4 (a), the cursor C moves to the position corresponding to the fifth symbol SY from the left and blinks.
Here, it is assumed that the circuit 1 is set to turn on the load from 9:00 on April 29th to 19:00 on May 5th every year. In the “priority program setting mode”, the letter “p” is displayed in association with the program number as shown in FIG. 14A, which indicates that it is the program number of the priority program. One program number is given to each pair of start date and time and end date and time of load control by the priority program, and whether the load is turned on or off from the start date and time to the end date and time is set. It can be specified. The maximum program number is set so that the load is turned on from the start date and time to the end date and time, and the load is turned off from the start date and time to the end date and time, for example, eight pairs can be specified in one circuit. Maximum capacity is specified. When the priority program is set over the maximum capacity, the display 21 displays "full" so that the priority program cannot be set.

In the "priority program setting mode", the start date and time is first set, and then the end date and time paired with the start date and time is set. Therefore, when selecting the "priority program setting mode" by the mode switch S _11, as shown in FIG. 14 (a), the upper left portion of the display unit 21 displays the right-pointing arrow having a vertical line to the left It is indicated that the start date and time is being set. In addition, here, the state in which the load is turned on from the start date and time to the end date and time is set, so that the character "ON" is displayed on the left end portion of the display 21. When the load is turned off from the start date and time to the end date and time, the mode switch S ₁₁ may be pressed again from the unset state (state of FIG. 14A). In that case, the character "OFF" is displayed at the left end of the display 21.

First, the start date / time is designated using the date / time designation switches S _{12 to} S ₁₇ . As for the start date and time, if the year designation switch S ₁₂ is pressed from the unset state, the year of the current date and time is displayed on the display unit 21, and the month, day, hour, and minute become January 1, 0:00. In addition, the month designation switch S ₁₃
Alternatively, when the date designating switch S ₁₄ is pressed, the year is not displayed on the display 21 and the month, day, hour, and minute become January 1, 0:00 (see FIG. 14B). That is, the method of setting the date and time is as described above.

After setting the start date and time as shown in FIG. 14C, if the mode switch S ₁₁ is pressed once,
The state shifts to a state in which the end date and time is set as in (d). At this time, a rightward arrow having a vertical line at the right end is displayed at the upper left portion of the display 21. In this state, similarly to the start date / time, the date / time designation switches S _{12 to} S ₁₇ are pressed to set the end date / time. If the year is not specified in the start date / time, the year specification switch S ₁₂ is not accepted.
If the specified end date and time is before the start date and time, the entire screen is blinked to indicate that the end date and time has been specified incorrectly. This state is released when the date and time specification switches S _{12 to} S ₁₇ are operated to input a valid end date and time. After setting the end date and time, press the mode switch S
_If you press ₁₁ , the program number is incremented and you are prompted to specify the next start date and time, as shown in FIG. Therefore, when setting the program continuously, the setting of the start date and time and the end date and time may be repeated.

To end the setting of the priority program, press the mode switch S ₁₁ in the state where the next program number is displayed and the start date and time is not set (state as shown in FIG. 14E), Display 2 as shown in FIG.
And unset a character is displayed in the "OFF" at the left end portion of the 1, can press the mode switch S ₁₁ further in this state. That is, in the unset state in which the character "ON" is displayed at the left end of the display 21, the mode switch S ₁₁ is continuously pressed twice, and the character "OFF" is displayed at the right end of the display 21. When the mode switch S ₁₁ is pressed once in the unset state, the mode is changed to the next mode (“test execution mode”).

[0050]

According to the invention of claim 1, eight or more day-of-the-week designating sections corresponding to every day of the week and one or more specific days are provided, and the days for controlling the load at the same time are designated by the day-of-week designating section. Since the time schedule for controlling the load is assigned to each day of the week designation section by the method of specifying all at once, if one time is set, the days for which the load is controlled will be set at that time. The time schedule can be set in units of one day by a simple operation of designating the day of the week by the day of the week designation section. This means that when time schedules for each day of the week have a common part, the labor of time-consuming time inputting work can be significantly reduced as compared with the case of inputting the time for each day. In addition, since the day of the week designation section has one or more items corresponding to a specific day different from the day of the week, a time schedule different from the normal day time schedule is set in the specific day on the specific day. It is possible to do so, and there is an advantage that it is possible to deal flexibly when setting a time schedule different from usual. Furthermore, the load is controlled based on the time schedule assigned by the day of the week designation section on the days specified by the specific day setting section, and on other days the time schedule assigned to the day of the week specified section corresponding to the day of the week obtained by the timekeeping means. Since the load is controlled by, the time schedule only needs to be changed for a specific designated day, and the time schedule for other days is automatically set based on the day of the week. Moreover,
Since the day to control the load can be specified by year, month, and day, the program can be set for a long period of time within the range allowed by the storage means, and once the program is set, maintenance of the program can be performed. It has the advantage of being unnecessary over the long term. In addition, the specific day setting section and the day of the week
Load with priority over the time schedule assigned by the designated section
It is possible to specify the priority program that controls
By the time schedule by the day setting section and the day of the week designation section
Even if we can not respond, one-shot by the priority program
The load can be controlled dynamically. Load on priority program
Since the start date and time and the end date and time of control of
It is also possible to support continuous load control over a period.

According to a second aspect of the present invention, the date for controlling the load is specified by one of year / month / day and month / day, and the date and time for controlling the load in the program stored in the storage means is the year. When the date is included, the load is controlled only for the designated one day, and when the date for controlling the load in the program stored in the storage means does not include the year, the load is controlled on the same day every year. If not specified, the same operation can be repeated every year, and the load can be controlled over a long period of time without increasing the capacity of the storage means.

According to the third aspect of the invention, since the current year obtained by the timekeeping means is displayed on the display means as the initial value of the year when the date and time is not set, the latest year is irrespective of the year at the time of factory shipment. Can be displayed. This means that when setting the date and time, an initial value close to the year to be set can be given, which leads to a reduction in the work time for setting the date and time.

According to the invention of claim 4 , when the value of the day of the designated date and time exceeds the last day of the month, the day value is corrected to the last day of the month, so that it is possible to prevent setting an impossible date. There is an advantage that is done.
