Abstract

PURPOSE:To enable the checking of a program simply and in a short time without altering counting date by providing a function to display the date at which control state of a load changes following the set date after the setting of the date of starting retrieval and the control state in the order closer to the set date. CONSTITUTION:A program setting means 1a of an operating means 1 sets a plurality of programs with the date of controlling a load and the control state of the load at the date in a set to be stored into a memory means 2. When the date of starting retrieval of the program is set with a call switch of the operating means 1, only the date at which the control state of the load changes is read out together with the control state of the load after the set date (date displayed) and displayed 6 in the order closer to the set date. This enables the checking of the program without altering the date being counted 3 thereby eliminating the need for setting time again after the checking work. In addition, an output value of a counting means 3 will not be affected directly thereby eliminating a danger that the load will be controlled under the checking work.

Description

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 load control date / time and control state program.

[0002]

2. Description of the Related Art Generally, in an electronic time switch,
When checking the set program, the current date and time measured by the timekeeping means built into the time switch is changed manually, and a predetermined output is generated or a predetermined display is made at the date and time set by the program. It is common to see if it is done.

[0003]

However, if the operation of the program is confirmed by the above-mentioned method, the setting of the timekeeping means is changed. Therefore, it is necessary to reset the timekeeping means to the current date and time after confirmation. Therefore, there is a problem that the confirmation work of the program becomes troublesome. Further, in the above method, when the program confirmation work is performed in the state where the load is connected, the load is controlled according to the change in the output, so that the load may be operated carelessly, which may be dangerous. In order to prevent such a danger, it is necessary to carry out the program confirmation work with the load removed, which also causes a problem that the program confirmation work becomes troublesome.
In addition, if the load control status is set to overlap (for example, the load on periods are overlapped by multiple programs), the load does not predict the behavior. However, in the above method, it takes time to find out which program should be modified, especially when a large number of programs are registered,
When the relationship between the programs is complicated, there is a problem that it takes a lot of time to modify the programs.

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems, and makes it possible to confirm a program without changing the date and time measured by the clock means, thereby simplifying the program confirmation work. Another object of the present invention is to provide an electronic time switch that can be performed in a short time and that can easily detect erroneous setting of a program.

[0005]

In order to achieve the above-mentioned object, a program setting means for setting a date and time for controlling a load and a program corresponding to a load control state at each date and time, A storage means for storing a plurality of programs, a clock means for counting the current date and time and a current day of the week, and a load according to the program when the current date and time matches the date and time of any program stored in the storage means. Control means for controlling the, the display means having an area for displaying the date and time and the control state of the load, the operation means operable to read the program stored in the storage means, and the search is started by the operation means. When the date and time to be set is set, the date and time when the load control state changes after the set date and time and the load control state are displayed in order from the set date and time. It's and a program confirmation means for sequentially displayed on the stage.

According to the second aspect of the present invention, each program is stored in the storage means in the form of being given a unique program number, the display means has an area for displaying the program number, and the program confirmation means is the date and time and In addition to the load control state, it has the function of displaying the program number of the corresponding program on the display means.

[0007]

According to the first aspect of the present invention, the operating means capable of operating to read out the program stored in the storage means and the setting of the date and time to start the search change the load control state after the set date and time. A program confirmation means is provided for sequentially displaying the date and time and the control state of the load on the display means in the order close to the set date and time. Since the program is read from the storage means and displayed on the display means, the clock means measures the time. You can check the program without changing the date and time. As a result, the work of resetting the time of the timekeeping means after the work of checking the program becomes unnecessary. Further, since the confirmation work is performed without affecting the output value of the timing means, there is no danger that the load is controlled by the confirmation work, and conversely, the load can be controlled according to the program even during the confirmation. Therefore, it is not necessary to remove the load while checking the program,
Also in this sense, the confirmation work of the program can be performed easily and in a short time. Moreover, in the program confirmation work, if the date and time to start the program search is set, only the date and time when the load control state changes after the set date and time are sequentially displayed together with the load control state. The change is easy to recognize, and if there is an unexpected behavior, it can be easily detected.

According to the second aspect of the present invention, since the program number is displayed in addition to the date and time and the load control state during the confirmation of the program, which program is to be executed when an unexpected operation is found in the load control state. The cause can be easily recognized, and the work of modifying the program is facilitated.

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 . Also, of the two circuits of the power supply and the load, the circuit to be controlled is indicated by a number in the upper left part,
The off state is shown in the middle left part. On the front surface of the housing 20, a plurality of symbols SY corresponding to the operation modes described below 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 is provided. Further, four manual operation switches SW _{1 to} S for selecting a state in which the load is operated according to the set program and a state in which the load is turned on / off independently of the program.
W ₄ , an interrupt setting switch SW ₅ for selecting whether to turn on or off the load by an external interrupt signal, a master for setting a master-slave relationship for synchronization when connecting a plurality of units The slave selection switch SW ₆ is provided with operation selection switches SW _{7 to} SW ₁₀ (a timer operation and a pulse operation will be described later) for selecting which of the timer operation and the pulse operation is to be performed for each circuit. The manual operation switches SW _{1 to} SW ₄ correspond to each circuit of the power supply and the load. Slide switches are used for the switches SW _{1 to} SW _10, and push button switches are used for the other switches.

To specify the operation mode, press the mode switch S ₁₁ . Each time the mode switch S ₁₁ is pressed once, the cursor C moves to a position corresponding to the symbol SY representing the operation mode, and the cursor C blinks so that the currently specified operation mode 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 in which a time schedule (daily pattern) of one day is set for each day of the week, and a timer operation program and a pulse operation program are set. In addition, in the "weekly program setting mode", in addition to the daily patterns for 7 days in a week, the daily patterns for 2 days can be additionally set, so that a total of 9 daily patterns can be set. It has become. Therefore, in the "weekly program setting mode", a daily pattern that sets the correspondence between the time of day and on / off of the load 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 weekly time schedule, and is based on the assumption that an exceptional time schedule will occur sporadically. If an exceptional daily pattern for two days can be set in addition to the daily pattern of, 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 a day of the week for 7 days and a 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 by using a 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 a time schedule of one week. 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 designated 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 a 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 and day are specified without specifying the year. 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 / 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
Using ~ S ₁₇ , 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 specifying switch S ₁₂ , the month specifying switch S ₁₃ , and the day specifying switch S ₁₄ are used.

The "test execution mode" will be specifically described. First, by operating the mode switch S ₁₁ ,
As shown in (a), the cursor C is moved to the position corresponding to the second symbol SY from the right, and the "test execution mode" is selected. The cursor C is blink-displayed at this position. At this time, the date is not displayed. Here, in the explanation of the figure, 7:30, Monday, May 27, 1991.
The following shows how to check the program after the minute.

In the "test execution mode", first the year, month,

If pressed at the same time, the state returns to the unset state of FIG.

Then, the call switch S ₁₈ is pressed to display the program of the desired program number on the display. When the call switch S ₁₈ is pressed once, the date and time when the output changes in the future closest to the set time is displayed on the display 21 (see FIG. 7D). When the call switch S ₁₈ is further pressed, the date and time when the output is changed next is displayed on the display 21, as shown in FIG. After that, each time the call switch S ₁₈ is pressed, the program is displayed sequentially. That is, the time when the load is turned on and off is displayed alternately (see FIG. 7F). On the other hand, from this state, the date / time designation switches S _{12 to} S ₁₆
Press any of the to return to the state where the start time is set.
Here, as described above, when the control date and time of the load is specified without specifying the year, the load is controlled on the same day every year, and therefore the maximum time set in the time counting means 3 is set at the time of confirmation. The date and time may exceed. Therefore, when the maximum date and time set in the clock means 3 is exceeded, the display 2
Notify by displaying "End" on 1. After confirmation,
Press the mode switch S ₁₁ to proceed to the next operation mode. In the next operation mode, the test execution mode of the circuit 2 is set. If you press several times the mode switch S ₁₁ to end the "test run mode". The program checking operation described above is the same for both the timer operation program and the pulse operation program.

The above operation in the "test execution mode" is summarized as shown in FIG. That is, when the “test execution mode” is selected, the initial display of the unset state in which the date and time is not displayed on the display 21 is performed (step S
1). Next, the date / time designation switch S ₁₂ provided on the operation means 1
By pressing any one of to S ₁₆ (excluding the second specification switch S ₁₇ ) (step S 7), the time to start the program search is input (step S 2), and the call switch S ₁₈ is pressed (step S 3). Of the dates and times after the search start time (that is, the date and time displayed on the display 21) and the output changes, the closest date and time is searched (step S4). When you search for the date and time like this,
The set time, output state, and program number are displayed on the display 21 (step S5). Also, step S3
If the mode switch S ₁₁ is pressed without pressing the call switch S ₁₈ (step S6), the “test execution mode” is released (or the “test execution mode” of the next circuit).

[0024] Furthermore, if the program is not set, or if it is a priority program, it will be turned on for a long time of one week or more.
If you have made settings that do not change the off state,
As shown in FIG. 10, the search for the program is stopped at 0:00 on the same day one week after the start of the confirmation (see FIG. 10B). However, if the program is set, the program number and the output on / off state during this period are displayed. Further, when the program is not set, the program number and on / off display are not displayed.

By the way, even when the load ON / OFF periods set by the program overlap,
In the "test execution mode", the date and time when the output changes are searched and displayed. For example, in the timer operation program, as shown in FIG. 11A, the on time is 1 on Monday.
As shown in FIG. 11 (b), the pair of 8 o'clock (program P1) and the off time is 6 o'clock on Tuesday (program P2), and the on time is 2 o'clock on Monday (program P3) and the off time is 2 on Tuesday. When the pair of hours (program P4) is set, the control means 4 interprets as shown in FIG. 11 (c). That is, the program P1 in which the output first turns on is valid, the program P3 turns on the output, but the output is already on and there is no change, so the program number P3 becomes invalid. Further, next, the program number P4 is valid because the output is turned off, but is invalid because the output is already turned off in the program P2. In short, in the "test execution mode", it is displayed only that the program P1 is turned on at 18:00 on Monday and the program P4 is turned off at 2:00 on Tuesday.

Further, in the timer operation program, as shown in FIG. 12A, the off time is 10:00 (program P
8) is set, and as shown in FIG. 12B, the priority program is off from 1:00 to 7:00 (program P5) and off from 12:00 to 15:00 (program P).
If 6) is set, as shown in FIG. 12C, the output is turned on until 1 o'clock and from 7 o'clock to 10 o'clock. Therefore, in the "test execution mode", the display is made such that it is turned off by the priority program P5 at 1 o'clock, turned on by the priority program P5 at 7 o'clock, and turned off by the program P8 at 10 o'clock. Further, since the output is already off for the program P6, it becomes invalid.

The above-mentioned "test execution mode" is performed independently of the load control operation. That is, even when the "test execution mode" is being executed, the load is controlled at the date and time set by the program. Therefore, it is possible to confirm the program in the "test execution mode" with the load connected. Such an operation is performed by, for example, prefetching from the storage means 2 a program having a date and time closest to the current date and time after the current date and time measured by the clock means 3 and changing the output, and buffer it. It can be realized by configuring so that the output is controlled when the date and time in the buffer matches the date and time measured by the clock means 3. In this way, since the contents of the program can be confirmed by the "test execution mode" without affecting the control of the load, it is not necessary to attach or detach the load, and the confirmation work of the program becomes easy. ..

[0028]

According to the first aspect of the present invention, the operating means that can be operated to read out the program stored in the storage means, and the date and time when the search is started are set. A program confirmation means for sequentially displaying the changing date and time and the control state of the load on the display means in the order close to the set date and time is provided, and the program is read from the storage means and displayed on the display means. You can check the program without changing the date and time. As a result, the work of resetting the time of the timekeeping means after the work of checking the program becomes unnecessary. Further, since the confirmation work is performed without affecting the output value of the timing means, there is no danger that the load is controlled by the confirmation work, and conversely, the load can be controlled according to the program even during the confirmation. Therefore, it is not necessary to remove the load during the program confirmation work, and in this sense, there is an advantage that the program confirmation work can be performed easily and in a short time. Moreover, in the program confirmation work, if the date and time to start the program search is set, only the date and time when the load control state changes after the set date and time are sequentially displayed together with the load control state. The change is easy to recognize, and there is also an effect that it can be easily detected if there is an unexpected operation.

According to the second aspect of the present invention, since the program number is displayed in addition to the date and time and the load control state during the confirmation of the program, which program is to be executed when an unexpected operation is found in the load control state. This has the advantage that it can be easily recognized whether it is the cause and the work of correcting the program becomes easy.
