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 turning a load on or off at a preset time.

[0002]

2. Description of the Related Art Generally, in this type of electronic time switch, a date and time for controlling the load to be turned on or off is set in advance, and a current date and time measured by a built-in clock means coincides with the set date and time. Then, the load is controlled on or off. In addition to the functions of the basic time switch, the sunrise time / sunset time of the year (in the embodiment described later, the sunrise time / sunset time is used in a broad sense, and the twilight time at which twilight disappears, the twilight time) In other words, it is also necessary to include the meaning of dawn time. In other words, it is sufficient if the predetermined time in the evening and the predetermined time in the morning determined by the position of the sun can be used. There is also provided a solar time switch in which the on time and off time of the load can be determined based on the sunset time. This type of solar time switch can be used for controlling nighttime lighting, etc., and turns on the light at a time appropriately adjusted based on the sunset time, and appropriately adjusts the time based on the sunrise time. It is possible to control such that the lighting is turned on. By such control, the lighting time and the lighting time can be automatically adjusted in accordance with the sunrise time and the sunrise time that change every day. This type of solar time switch is configured so that the sunrise time and the sunset time can be corrected according to the use area (latitude / longitude).

An electronic time switch of this type is disclosed in Japanese Patent Application Laid-Open No. 7-14484. The apparatus described in this publication is provided with a test run key provided in an operation unit, and a test run program for displaying on-set time or off-set time of a stored time schedule in ascending order by operating the test run key. Therefore, when the test run key is pressed, the time schedule is displayed in order of time from Sunday to Saturday, and the output operation is automatically performed, so that the contents of the time schedule can be confirmed. However, confirmation of the content of the time schedule is limited to one week from Sunday to Saturday.

[0004] An electronic time switch is disclosed in Japanese Patent Application Laid-Open No. 5-232263. This publication has a function of displaying the date and time when the control state of the load changes after the specified date and time when the search start date and time is specified, and the control state in the order of closest to the specified date and time. However, the publication described in this publication searches for changes in the load control state on a weekly basis.
If the time schedule is set so that the load control status changes only once a day, the search start date and time will be displayed after the specified date and time when the load control status changes. Then, the date and time one week after the date and time when the load control state changes is displayed, and then the date and time when the next control state of the load changes (date and time after ten days) is displayed.
That is, when a time schedule in which the load control state does not change for a long period of time exceeding one week is set, even if the search start date and time is specified, the date and time when the load control state changes after the specified date and time or the control The status cannot be displayed.

[0005] An electronic time switch disclosed in Japanese Patent Application Laid-Open No. Hei 4-9690 is also known. The publication describes that the time schedule is confirmed by fast-forwarding the time display on the display, and the time schedule that has been set can be confirmed by temporarily stopping the fast-forwarding of the time display. is there. However, since the one described in this publication is a weekly time switch, it is possible to confirm a time schedule set for only one week from Sunday to Saturday.

[0006]

As described above, various time switches are provided, and the set time schedule can be confirmed. However, the confirmation of the time schedule is limited to one week. It is not possible to confirm the long-term time schedule.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an electronic time switch capable of confirming a set time schedule without limitation of one week.

[0008]

According to the first aspect of the present invention, a clock means for measuring the current date and time, a set date and time for controlling the load, and the content of the load control are combined to achieve the above object. Time schedule storage means for storing the time schedule, comparison means for comparing the set date and time stored in the time schedule storage means with the current date and time measured by the clock means, and matching between the set date and time and the current date and time by the comparison means Is detected, load control means for controlling the load according to the time schedule, monitor mode switching means for selecting a monitor mode for reading the time schedule stored in the time schedule storage means, and the read time schedule are displayed. Display means and a time schedule for turning on the load after the day in monitor mode Than it and a search means for displaying on the display means at least one of the date and time of the subsequent time schedule with Search Le.

According to this configuration, in the monitor mode, the time schedule for turning on the load after the current day is searched and displayed on the display means in sequence, so that the time schedule can be confirmed without restriction of one week. Here, the current day includes the current date measured by the clock means and the date specified by the setting date setting means described later. In addition, since the time schedule for turning on the load is first searched and displayed, even when the load is kept off for a relatively long time, the date and time when the load will be turned on next can be easily confirmed. That is, an electronic time switch that controls using a predetermined time in the evening or a predetermined time in the morning as in the invention of claim 2, or an electronic time switch that can perform the holiday setting mode as in the invention of claim 3. Even so, the operation can be checked.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. In the following, the terms sunrise time and sunset time are used as astronomically determined times based on the position of the sun on the sky, but when controlling the lighting load, twilight appears before sunrise It is desirable to use the dawn time instead of the sunrise time, and to use the sunset time at which twilight disappears after sunset, instead of the sunset time. In other words, if the surroundings are bright, there is no need to turn on the lighting load, so there is no need to turn on the lighting load while there is twilight.Moreover, the time difference between the dawn time when the twilight appears and the sunrise time and the sunset time when the twilight disappears Since the time difference from the sunset time changes depending on the season, it is better to use the dawn time or the sunset time as a reference than to use the sunrise time or the sunset time as a reference. Therefore, it does not prevent reading the sunrise time / sunset time from the dawn time / sunset time.

The clock means 1 shown in FIG. 1 measures the current date and time, and the comparing means 2 compares the date and time preset in the time schedule storage means 3 with the current date and time measured by the clock means 1. When the comparison unit 2 detects coincidence between the two dates and times, the load control unit 5 controls the load 6 to be turned on or off based on the on / off information of the load 6 set together with the date and time in the time schedule storage unit 3. I do. Here, the load 6 uses an illumination load. The sunrise time / sunset time is obtained by the calendar means 4 based on the current month and day. When the time schedule storage means 3 is set to control the load 6 using the sunrise time and the sunrise time. , The sunrise time and the sunrise time obtained by the calendar means 4 are used.

The calendar means 4 divides Japan into a plurality of districts, and stores a set of annual sunrise time and sunset time for each district only for the odd days (1, 3,...) Of each month. In addition, the sunrise time and the sunset time of the even-numbered day are obtained from the sunrise time and the sunset time of the odd-numbered day before and after the even-numbered day (2 days, 4 days,...) Of interest. And the sunrise time. That is, if the current month and day counted by the clock means 1 are odd days, the stored data is output, and if the current month and day are even days, the interpolated data is output. When controlling the load 6, the sunrise time
In addition to using the sunrise time, it is also possible to use a time obtained by adding or subtracting an appropriate time to the sunset time and the sunrise time, and the calendar time setting means 9 can perform this processing.
That is, the calendar time setting means 9 adds or subtracts an appropriate time to the sunrise time / sunrise time, and if neither addition nor subtraction is performed, the sunrise time / sunrise time itself is used. The time thus determined is hereinafter referred to as calendar time. Here, the calendar time includes year, month, day, and day of the week.

A fixed time can be used as the time for controlling the load 6, and a fixed time setting means 10 is provided for setting the fixed time. The fixed time input from the fixed time setting means 10 is stored in the fixed time storage means 11. The time schedule storage means 3 registers a time at which the load 6 is controlled and information as to whether the load 6 is to be turned on or off at that time as a set as a time schedule. Each set is classified for each day. It is registered. The time when the load 6 is controlled can be a sunrise time or a sunset time. Since the load 6 is a lighting load, it is controlled by five types of operation patterns as shown in FIG. 2 (in FIG. 2, a hatched portion indicates that the lighting load is being lit). That is, an operation pattern 1 in which the light is turned on at the sunset time and the light is turned off at the sunrise time as shown in FIG. 2A, and an operation pattern 2 which is turned on at the sunset time and turned off at the fixed time as shown in FIG. The operation pattern 3 turns on at a fixed time and turns off at sunrise time as shown in FIG. 2 (c), and the fixed time at which there is no traffic at night as shown in FIG. An operation pattern 4 in which the light is turned off once and turned on again at the fixed time before dawn and turned off at the time of sunrise, and FIG.
There is an operation pattern 5 in which the light is turned on at a fixed time and turned off at a fixed time as shown in FIG. In other words, one time schedule determines the control of the load 6 from the sunset time to the sunrise time of the next day. These operation patterns are stored in ROM
The operation pattern is previously registered in an operation pattern storage unit 7 composed of an EEPROM, and an operation pattern selection unit 8 selects an operation pattern for controlling each load 6.

Since the operation pattern determines whether the load 6 is turned on or off, if a calendar time or a fixed time is allocated according to each operation pattern, a time schedule for operating the load 6 is determined. be able to. By the way, since the time schedule is often set periodically in one week, the time schedule can be set in weekly units. That is, the day of the week can be designated by the operation day setting means 41, and the designated day is temporarily stored in the operation day storage means 42.

Further, when there is a relatively long holiday, such as when used in a school or factory, the output for controlling the load 6 may be constantly turned off. While the normal operation pattern is set on a weekly basis, a long holiday is specified by the start date and end date of the period. For setting such a holiday, a holiday period setting means 43 for setting a start date and an end date of the holiday is provided, and the start date and the end date designated by the holiday period setting means 43 are stored in the holiday period storage means 44. Is stored temporarily.

As described above, when a day of the week is specified, an operation pattern is selected, and a calendar time or a fixed time is specified according to the operation pattern, or a start date and an end date of a holiday period are specified. , Time schedule generating means 1
In 2, the operation pattern selected by the operation pattern selection means 8, the calendar time set by the calendar time setting means 9, the fixed time stored in the fixed time storage means 11, and the operation stored in the operation day storage means 42 A time schedule is created by appropriately combining the start date and the end date of the holiday period stored in the day of the week and holiday period storage means 44, and the created time schedule is stored in the time schedule storage means 3. That is, when setting a normal time schedule, an operation pattern is linked to an operation day of the week, and a calendar time and a fixed time are linked according to the operation pattern.
Also, when setting a holiday time schedule,
From the start date to the end date, the time schedule is canceled so as to keep the load 6 off.

Display means 13 is provided for displaying the process of setting the time schedule as described above, displaying the confirmation of the time schedule after setting, and displaying the current date and time. It is controlled by the processing means 14 and the input operation display processing means 51. The monitor mode can be selected by the monitor mode switching means 52 to confirm the set time schedule. When the monitor mode is selected, the first date for confirming the time schedule is set. If the date is not set in the monitor mode, the current date measured by the clock means 1 is stored in the set date storage means 53 as the first date for checking the time schedule. The date stored in the set date storage means 53 is displayed on the display means 1 through the input operation display processing means 51.
3 is displayed. On the other hand, the first date for checking the time schedule can be arbitrarily specified. When specifying the date, the date is input by the set date setting means 54, and the date is stored in the set date. It is stored in the means 53 and displayed on the display means 13.

When the selection operation means 56 composed of a push button switch is pressed while the current date or the specified date is stored in the set date storage means 53, the operation date search means 57 sets the time schedule. The stored date is retrieved from the time schedule storage means 3, stored in the monitor date storage means 55, and displayed on the display means 13 through the input operation display processing means 51. When the selection operation means 56 is further pressed, the operation time search means 58 reads out the time schedule of the day stored in the monitor date storage means 55 in chronological order for each press operation, and displays it on the display means 13.

When the last time schedule stored in the monitor date storage means 55 is displayed on the display means 13 and the selection operation means 56 is then pressed, the year and month in which the time schedule is set The date is retrieved by the operation date retrieval means 57, stored in the monitor date storage means 55, and displayed on the display means 13. If a further push operation is performed, the operation time search means 58 searches the time schedule in order of time for each push operation. The time schedule of the day is displayed on the display means 13 in chronological order. Such a process is repeated, and the time schedule is sequentially displayed on the display unit 13 every time the selection operation unit 56 is pressed. As described above, the search means is constituted by the operation day search means 57 and the operation time search means 58.

In other words, when the date stored in the set date storage means 53 is a day of the week without an operation day, the date on which the operation day is first set after the stored date is stored in the monitor date storage means. If the date stored in the monitor date storage unit 55 is during the holiday period, the date on which the first operating day is set after the day after the end date of the holiday period is the monitor date storage unit 55. It is stored in. The date stored in the monitor date storage means 55 is displayed on the display means 13 through the input operation display processing means 51, and the time schedule is sequentially read out by the pressing operation of the selection operation means 56 as described above.
An upper limit is set for the date on which the time schedule can be set, and the character “End” is displayed after the upper limit is reached or the last time schedule stored in the time schedule storage unit 3 is displayed. It is so.

As shown in FIG. 3, the above-mentioned solar time switch is constituted mainly by a signal processing circuit 20 composed of a microcomputer. That is, the signal processing circuit 20 includes a CPU, a ROM, a RAM, and various ports, and forms a portion surrounded by a dashed line in FIG.
A program for realizing each function is stored in a ROM, and the time schedule storage unit 3 is realized by a RAM. Further, the clock means 1 measures time based on a clock signal supplied to the signal processing circuit 10 from a clock oscillation circuit 21 having a crystal oscillator. The load control means 5 includes a relay 22 inserted into a power supply path of the load 6 and a relay drive circuit 23 that drives the relay according to a signal output from the signal processing circuit 20. The relays 22 are provided for two circuits, each having a c-contact. That is, each relay 22 includes three relay terminals 34b, that is, a normally closed contact terminal, a normally open contact terminal, and a common contact terminal. Further, the operation pattern selecting means 8, the calendar time setting means 9, the fixed time setting means 10, the monitor mode switching means 52,
The set date setting means 54 and the selection operation means 56 are configured by combining a plurality of switches S _{1 to} S ₁₂ as operation parts. The switches S _{1 to} S ₁₂ are connected to the key matrix unit 24, and the key matrix unit 24 is connected to any of the switches S ₁ to S ₁₂ .
Recognizes whether S ₁₂ has been operated to the signal processing circuit 20 gives operation information of the switches S ₁ to S _12. Signal processing circuit 20
The display means 13 includes a liquid crystal display 25 of a segment type display showing various information by displaying and hiding characters and figures arranged in fixed positions corresponding to various information, A plurality indicating the operation state (here, 3
) Light emitting diodes 26 _{1 to} 26 ₃ , signal processing circuit 2
An LED lighting circuit 27 for turning on / off the power supply from the power supply circuit 28 to the light emitting diodes 26 _{1 to} 26 ₃ based on the signal output from 0 to control the turning on and off of the light emitting diodes 26 _{1 to} 26 _3. .

The power supply of the internal circuit is a power supply circuit 28 for stepping down and rectifying a commercial power supply connected to a power supply terminal 34a to a constant voltage.
Supplied by This type of power supply circuit 28 can be configured using a step-down transformer and a series regulator, but a switching regulator using a step-down chopper circuit is desirable for miniaturization. LED lighting circuit 2
As described above in 7, the starting and turns off the light emitting diodes 26 ₁ to 26 ₃ using the output voltage of the power supply circuit 28 in response to the output signal from the signal processing circuit 20. Further, after the output voltage of the power supply circuit 28 is passed through the LED lighting circuit 27, a voltage for driving the relay is obtained by the relay voltage circuit 29, and a voltage for driving the signal processing circuit 20 is obtained by the VDD voltage circuit 30. ing. Signal processing circuit 20
When the power failure detection circuit 31 detects a drop in the output voltage of the VDD voltage circuit 30, power is supplied from the power failure compensation battery 32 to the signal processing circuit 20 because the clock means 1 must be operated even when the commercial power supply fails. In this way, the clock means 1 does not stop counting during a power failure. When the power of the signal processing circuit 20 is turned on or when some abnormality occurs and a reset is instructed by the switch S ₁ (described later), the reset circuit 33 performs a reset process to initialize the signal processing circuit 20.

The above-described solar time switch has a body 35 having an appearance as shown in FIG. This container 35
Has a size and a shape standardized as a common size of a distribution board formed of an insulating material such as a synthetic resin, and has a DIN rail (a U-shaped cross section and a U-shaped cross section) in the distribution board. (A mounting rail that is arranged in a distribution board and is a rail in which a holding piece is extended outward on each of the legs in the shape of a circle.)
It is configured so that it can be attached using a screw or inside a distribution board using screws. Vessel 3
As shown in FIG. 5, a plurality of switches S ₁ to
With S ₁₂ are arranged, the liquid crystal display 25 and light emitting diodes 26 ₁ to 26 ₃ which is a display unit 13 are arranged. A terminal block 36 is provided on one side of the body 35, and two power supply terminals 34a, each of which is a threaded terminal, and two sets of three relay terminals 34b are provided. The power supply terminal 34a is connected to a commercial power supply, and each set of the relay terminals 34b corresponds to one load 6 of the circuit.

By the way, the light emitting diode 26 ₁ is lit while being powered from a commercial power supply is for energizing the display.
The light emitting diodes 26 ₂ and 26 ₃ indicate the state of output to each load 6. When an output for turning on the load 6 of each circuit is generated, the light emitting diode 2 corresponding to each circuit is generated.
6 _2, 26 ₃ is turned, respectively. Switch S ₁ is a reset switch composed of a push button switch which is press operation using a thin tool, such as a tip of a ball point pen, such as when to erase all or settings when some abnormality occurs, the reset switch S _{When 1} is pressed, the reset circuit 33 is activated and the signal processing circuit 20 can be reset. The switches S ₂ and S ₃ arranged at positions corresponding to the light emitting diodes 26 ₂ and 26 ₃ are three-position slide switches. At the center position, the load 6 is automatically switched according to the time schedule set in the time schedule storage unit 3. The light is turned on and off, and the load 6 is continuously turned on at the one end position, and is kept off at the other end position.

The other switches S _{4 to} S ₁₂ are pushbutton switches, and the mode switch S ₄ has a function of selecting an operation mode of the signal processing circuit 20. The selectable operation modes include a normal mode in which the load is controlled when the current setting measured by the clock means 1 matches the time stored in the time schedule storage unit 3, and a time adjustment of the current time of the clock means 1. And a setting mode for setting a time schedule for each circuit corresponding to each load 6 in the time schedule storage unit 3, and a setting mode for setting a time schedule for each circuit in the time schedule storage unit 3. There is a holiday setting mode in which is controlled by a time schedule different from weekdays. In other words, mode switching means for switching a holiday setting mode by the mode switch S ₄ is realized. Setting mode is of setting the time schedule to the load 6 in the two circuits, has a mode switch S ₄ to be sequentially selected load 6 by press operation. In other words, it than it is possible to select a mode to cyclic by one-press operation of the mode switch S _4, the normal mode for each press operation of the mode switch S ₄ → watch and District mode → setting mode (the first load ) → setting mode (second load) → holiday setting mode → normal mode. Switch S ₈ to S ₁₁ are assigned different functions depending on the operation mode. The upper side of the liquid crystal display 25 is disposed mark M ₁ ~M ₅ of triangular shape as in FIG. 6, the marks M ₁ ~M ₅ were labeled on the device body 35 around the liquid crystal display 25 characters ( “Normal”, “Clock / District”, “Output 1”, “Output 2”, “Holiday”). Therefore, when selecting an operation mode by the mode switch S _4, the position of the mark M ₁ ~M for the character indicating the operation mode
Only ₅ is the display state, the other marks M ₁ ~M ₅ shows the operation mode in the non-display state.

In the normal mode, the current time and the district number are displayed in areas D ₁ and D ₂ , respectively. The operation pattern of the load 6 is displayed on the operation pattern display area D _3.
It will be described later display contents of the operation pattern display area D _3. The above-mentioned district numbers are obtained by dividing the whole country into a plurality of districts and assigning numbers.

In the normal mode, the monitor mode switching means 5
The monitor switch S ₅ to be 2 can operate the monitoring function when press operation, comprising a time schedule can be confirmed on the screen of the liquid crystal display 25. When the monitor function operates, the character “monitor” is displayed on the liquid crystal display 25. When the monitor function is operated, the indicator ([output] [1] [2]) indicating each circuit of the load 6 on the liquid crystal display 25 becomes a blink display (display in which display / non-display is repeated in a short time). the press operation of the mode switch S ₄ which functions as a selection operation unit 56 at this time, so that it is possible to select one of the circuits. If press operation monitoring switch S ₅ after selecting circuit of the load 6, the current date is displayed in the area D _1, thereafter no longer accept the switch S _4. In this state, the switch S ₈ ~S ₁₀ By press operation If you want to see the time schedule for the other date,
The date can be changed. After specifying the date from the time schedule storage unit 3 for each push operation of the monitor switch S ₅ is read out time schedule is displayed on the liquid crystal display device 25 can confirm the time schedule. Time schedule that is displayed will be a thing of the subsequent day you operate the monitor switch S _5. To release the monitor function to operate the cancel switch S _6. In monitor mode, but various switches S ₈ ~S ₁₀ is operated does not affect the time schedule.

In the clock and district mode, switches S _{8 to} S ₁₀
Thus, the date, hour, minute, second and district can be input. Years, hour and minute are displayed in the area D _1, day, s, district (district number) is displayed in the area D _2. When the date is displayed, it can be identified by displaying an apostrophe, and when the district number is displayed, it can be identified by displaying the letters "district" and parentheses.

In the setting mode, the number corresponding to the selected load 6 is blinked. Here, the setting switch S
_An operation pattern is selected for each of the ₁₂ pressing operations. That is, the setting switch S ₁₂ functions as an operation pattern selecting means. When the operation pattern is selected, and displayed according to the operation pattern view is disposed in the region D ₃ "day ON""Ordinary" each character of the "scheduled", "sunrise" operation pattern in accordance with the operation pattern The character is in a non-display state and the displayed character is blinked. For example, when the operation pattern 1 shown in FIG. 2A is selected, only the characters “sunset” and “sunrise” are blink-displayed as shown in FIG. Also, the mark M ₃ to indicate that the circuit is selected for the first load 6 at this time is blink.

As described above, in the present embodiment, two fixed times can be controlled between the sunrise time (calendar time) and the sunrise time (calendar time). It is controlled by a point. Therefore, as shown in FIG. 1, a dot indicating a time (a circle, a polygon, etc.)
15 and a wide bar 16 indicating the control state of the load 6 are used to show the operation pattern. That is, when the load 6 is controlled at the sunset time, the fixed time, and the sunrise time, the dot 15 is displayed, and when the load 6 does not change at that time, the dot 15 is not displayed. Further, the bar 16 is displayed during the period when the load 6 is on, and the load 6 is not controlled during the period when the bar is not displayed. In this manner, the arrangement of the dots 15 and the bars 16 indicating the operation pattern is provided for each load 6. That is, in the present embodiment, since the loads 6 of two circuits can be controlled, two rows of the dots 15 and the bars 16 are provided. Furthermore, in order to help understand the meaning of each dot 15, "sunset", "periodic", "periodic"
Characters "Hiji" are arranged, and display / non-display of these characters is selected according to the operation pattern. put it here,
Since each time is represented by two characters and these characters are selected, it is possible to provide a display sufficient and necessary for the interpretation of the meaning while using the minimum space. A triangular mark is written between the characters to indicate the time direction. Further, on the left side of each row, a marker 17 [1] [2] is arranged to identify the circuit of the load 6.

Thus, when the first load 6 is selected, only the sign [1] is displayed and the "sunset"
The text “Hiji” and a triangle mark blink,
Only the dots 15 corresponding to "sunset" and "sunrise" are displayed. Everything about the bar 16 is displayed. ON time day by pressing operating the switch S ₁₁ in this state, by designating earlier, the late relative to sunrise time, display of the "early", "late" is made in the liquid crystal display 25 Sunrise time, by entering the desired time,
A calendar time obtained by adding or subtracting a desired time to the sunrise time can be set. That is, the switch S ₈ to S ₁₁ will function as a calendar time setting means 9.

On the other hand, the operation pattern 4 shown in FIG.
When it is done, "sunset" "on time" "on time" "sunrise"
All characters are displayed as blinking, and from "Sunset"
Each bar 16 of "hour", "on time" to "sunrise" is displayed.
You. Also in this case, switch S₈~ S ₁₁Each time by using
The time can be entered. In other words, sunrise time and sunrise time
A predetermined time can be adjusted, and the fixed time is
You will have to enter the time directly. Each time is set according to the setting.
Switch S₁₂A state in which the next time is set by pressing
Move to Thus, the switch S₈~ S₁₁Is fixed time
It also functions as the setting unit 10. Works as described above
Time assignment by assigning time to patterns
A schedule is created.

The switch S ₇ is a for daylight saving time setting, the switch S when it is not in daylight saving time setting state
_{When 7} is pressed, the current date and time is advanced by one hour, and a daylight saving time setting state is set. In addition, the liquid crystal display 25 displays “+
1h "is displayed. When the press operation of the switch S ₇ is in the daylight saving time setting state is canceled daylight saving time setting state, the current time 1 hour late "+ 1h" is hidden.

By the way, when the time schedule is set as described above, the load 6 is turned off at the sunrise time, but depending on the setting of the fixed time, the fixed time is later than the sunrise time. Could be. For example, when a time schedule is set so that the lighting load is turned on by setting an early morning time as a fixed time, the sunrise time may be earlier than the fixed time in summer. In such a case, since there is a fixed time for instructing lighting after the sunrise time for instructing to turn off, if the load 6 is controlled as it is, the load 6 remains lit during the day.
Therefore, when controlling the load 6 to be turned on at a fixed time, the signal processing circuit 20 determines whether the fixed time has passed the sunrise time (calendar time), and the fixed time has passed the sunrise time. , The control of the load 6 at a fixed time is prohibited. That is, the signal processing circuit 20 is provided with the malfunction prevention means.

In this embodiment, since the load 6 of two circuits can be controlled, the load 6 can be used for controlling only one circuit. Further, although the time schedule can be set in units of one week, it can be used for setting the time schedule in units of 24 hours. Therefore, by setting the repetition cycle of the time schedule (1 week type, 24 hour type) and the number of circuits of the load 6 (1 circuit type and 2 circuit type) in advance, it is unnecessary when using in a field where the use is limited. Display is not performed. That is, the signal processing circuit 20 is provided with model setting means realized by a memory switch, and limits functions using information stored in the model setting means at the time of initialization processing at the time of startup. The display according to the function is performed.

That is, a model discriminating means for reading the information stored in the model setting means in an initialization process at the time of activation is provided as a program, and the display processing means 14 controls the liquid crystal display based on the discrimination result by the model discriminating means. The display content of the display 25 is changed. It is only necessary not to display the day of the week when the 24-hour type is selected. However, when the one-circuit type is selected, the sign [1] is written below the sign [Output]. Then
It is unnatural because of the impression that there are other controllable circuits. Therefore, [1]
The display of [Output] and [1] can be selected in the form of [Power], and when the [Output] display is selected, the upper [Output] is hidden. . Therefore, it is possible to recognize the one-circuit type without a sense of incongruity. Further, since the position of the sign of [output] is different between the two-circuit type and the one-circuit type, this also facilitates recognition of the model.

The operation of this embodiment will be briefly described below. FIG. 7 shows the overall operation of the signal processing circuit 20. When the power is turned on or reset, an initialization process is first performed (S1). At this time, model determination is performed, and subsequent operations are made to correspond to the determined model. Immediately after the power is turned on, because the time schedule is not set immediately after a reset, a state waiting for input to the time schedule is set by operation of the switch S ₄ to S ₁₂ as described above (S2). If there is any input operation, a display corresponding to the operation is performed on the liquid crystal display 25 (S
3) At this time, it is determined whether or not the normal mode is set (S4).
In the normal mode, the presence or absence of a power failure is determined (based on the output of the power failure detection circuit 31) (S5). In the event of a power failure, the output signal to the outside of the signal processing circuit 20 is stopped and only the clock means 1 measures time (S6). . If the power failure is eliminated (S7), the operation returns to the original operation again (S8). If it is determined in step S5 that power is supplied, the load 6 is controlled according to the current date and time measured by the clock means 1 and the time schedule registered in the time schedule storage means (S8).

An example of the setting operation of the timer switch will be described below. In the following, the load 6 connected to the output 1 is operated from Monday to Saturday in the operation pattern 4 shown in FIG.
