Description

[Detailed Description of the Invention] Industrial Application Field The present invention sets on-time and off-time for each day of the week, which is suitable for centralized management systems such as air conditioning equipment and lighting equipment, automatic driving control systems, etc. This invention relates to a weekly program timer device that can perform

Conventionally, in this type of weekly program timer device, (a) the on/off time for each day of the week is set by a common key operation for each day of the week, and one or two display devices are used for the same purpose; (b) One that uses a mark sheet etc. to input the weekly on/off operation from a reading device, (c) Keyboard,
Some devices set and display on/off times using a combination of CRT, host computer, etc.

Problems to be Solved by the Invention In these conventional weekly program timer devices, especially in the case of (a), the cost of the device itself is relatively low because it is easy to set the on/off time and configure the display part. Although it has the advantage of being able to achieve this, key operations are always required to check the on/off time settings for a week, and it is difficult to understand the overall operation.

On the other hand, in the case of (b) and (d), although extremely complex or complicated on/off operations are possible, the cost of the equipment is extremely high, and furthermore, the handling requires considerable specialized knowledge or This requires skill and has some drawbacks in terms of ease of operation.

In addition, these conventional methods can be
Alternatively, when the power is restored, the timer output signal may be turned on or off inadvertently, which poses operational difficulties.

The present invention has been made in view of the above, and aims to provide a weekly program timer device which is primarily aimed at improving operability and operational performance, and which can be realized at relatively low cost.

Means for Solving the Problems In order to solve the above problems, the weekly program timer device of the present invention includes a clock section that clocks time;
A current time display section that displays the current time; a day display section that displays each day of the week; an adjustment section that adjusts the current time and day of the week; a timer time setting section comprising seven sets of on-time setting switches and off-time setting switches capable of setting and displaying;
A timer output signal is generated, and it is determined whether or not it is time for adjustment in the adjustment section, whether or not it is time for setting in the timer time setting section, or whether or not it is time for power outage recovery, and the timer is enabled. It is composed of a main control section that emits a signal, and a signal output section that inputs the signal emitted by the main control section and outputs it to the outside.

In particular, as a means of setting and displaying the timer time,
An on-time setting switch and an off-time setting switch are provided for each day of the week, and it is possible to identify that the switch is in normal operation, not when adjusting the current time and day of the week, when setting the timer time, or when recovering from a power outage. This is an attempt to significantly improve the conventional problems by outputting a signal that can be used separately from the timer output signal.

Effects The present invention uses the above configuration, particularly the timer time setting section, to independently set different on and off times for each day of the week for the timer over a week, and to set all the set times at once. Since the timer can be checked, the timer time can be easily set and done with extremely few errors, resulting in a dramatic improvement in operability. Although seven sets of switches for setting the on time and for setting the off time are required, this can be realized at relatively low cost.

Furthermore, in case the timer output signal is uncertain, such as when adjusting the current time/day of the week or setting the timer time, the device is configured to output a timer enable signal, increasing the reliability of timer operation. becomes.

Embodiment A weekly program timer device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a block diagram of a weekly program timer device according to an embodiment of the present invention. Second
The figure is a block diagram of the embodiment of FIG. 1.

First, in Fig. 1, 1 is the current time display section,
It consists of a light emitting element 2 that displays AM/PM, a numeric display element 3 that displays hours and minutes, etc., and displays the current time in a 12-hour system. 4 is a day of the week display section, which is made up of seven light emitting elements 5, and any one of the light emitting elements 5 lights up to display the day of the week. 6 is an adjustment unit for adjusting the current time and day of the week; adjustment set switch 7;
It consists of an hour and minute adjustment switch 8 and a day of the week adjustment switch 9. A timer time setting section 10 sets an on time and an off time for each day of the week, and an on time setting switch 11 and an off time setting switch 14 are provided for each day of the week. The on-time setting switch 11 is a digital switch 12 that allows you to manually select and set the on-time in a 24-hour system using a 4-digit decimal number, and whether the on-time setting is valid as a timer operation or not. Enable/disable switch 1 to select whether to disable
It consists of 3. Similarly, the off time setting switch 14 is composed of a digital switch 15 and a valid/invalid switch 16. Reference numeral 17 is a setting display element in the timer time setting section 10 that lights up to indicate that the setting of the on time or off time is being changed. 18 is a timer output display element that displays the on/off state of the timer output signal output by this timer device;
Reference numeral 9 denotes an output inversion switch for arbitrarily inverting the state of this timer output signal by manual operation.

Next, in FIG. 2, reference numeral 20 denotes a DC power source for this timer device, which is either formed from a commercial power source or supplied from outside. Reference numeral 21 is a timekeeping section that counts time based on a built-in reference clock.
Reference numeral 22 denotes a main control section composed of a microcomputer, which is connected to each section of this timer device and centralizes and controls their operations. The main control unit 22 includes an on/off determination unit that compares and determines the set time of the timer time setting unit 10 with the current time displayed on the current time display unit 1 and the day of the week displayed on the day of the week display unit 4, and an adjustment unit 6. Whether or not it is time to adjust the
Alternatively, it is provided with output validity determining means for determining whether or not it is time to set the timer time in the timer time setting section 10, and whether or not it is time to recover from a power outage.
23 is a signal output section that outputs a timer output signal etc. generated by the main control section 22 to an external device. Reference numeral 24 denotes a backup power source mainly composed of a battery that can be recharged repeatedly, and when the DC power source 20 is turned off due to a power outage or the like, the low power consumption timer 21 and the main controller 22 are activated for a predetermined period of time. It supplies power to the memory section to continue timekeeping operations and cope with power restoration operations.

Next, the operation will be explained.

First, the current time display section 1, day of the week display section 4, adjustment section 6, clock section 21, and backup power supply 24 will be explained.

When the adjustment set switch 7 of the adjustment section 6 is pressed once, the main control section 22 detects this and enters the hour/minute/day adjustment mode. Therefore, operate the hour and minute adjustment switch 8 to adjust the current time displayed on the current time display section 1, operate the day of the week adjustment switch 9 to adjust the day of the week displayed on the day of the week display section 4, and then turn the adjustment set switch 7 again. Press to complete the hour/minute/day adjustment mode. Thereafter, the displays on the current time display section 1 and the day of the week display section 4 are updated via the main control section 22 by the timekeeping operation of the timekeeping section 21. Even if the DC power supply 20 is turned off, the backup power supply 24 allows the timekeeping section 21 to continue counting for a predetermined period of time (for example, 24 hours), and the memory section of the main control section 22 also stores the data stored before the power outage. Therefore, when the DC power supply 20 is restored, the main control section 22 reads the time data of the clock section 21 and the normal state can be restored.

Next, the operation of the timer time setting section 10 and the like will be explained.

When setting the on time and off time for each day of the week, the digital switch 12 provided in the on time setting switch 11 and the off time setting switch 14 corresponding to each day of the week in the timer time setting section 10 Operate the adjustment lever No. 15.
This adjustment lever has a rotary structure, and each of the four digits can be set independently. By manually operating this adjustment lever, you can set the desired ON time.
Adjust to off time.

On the other hand, the main control section 22 constantly reads the set time of the timer, and when it detects that the set time has been changed by this manual operation, it enters the timer setting mode and lights up the setting display element 17. Also, if the on time or off time is set incorrectly, for example to a value such as 16:05 that cannot be taken as a time in a 24-hour system, the corresponding day of the week will be displayed on the on time setting switch 11 or off time setting switch 14. The corresponding light emitting element 5 blinks to notify you of the error. When the set time is corrected to a normal value, the blinking display of the light emitting element 5 is canceled. If the set time is normal and the set time is not changed for a predetermined period of time (for example, 3 seconds), it is automatically assumed that the timer time setting has ended, and the setting display element 17 is turned off. Complete timer setting mode.

In addition, if you do not want to perform timer automatic operation regardless of the on time and off time set by the digital switches 12 and 15 for each day of the week, for example, normally timer automatic operation is performed every day throughout the week, but temporarily When you do not want the timer to run for just one day,
Valid/invalid switch 13 corresponding to each
Alternatively, if 16 is set to the "invalid" side, the on time or off time is ignored and timer operation is not performed. By returning the settings of the valid/invalid switches 13 and 16 to the "valid" side again, the timer can be operated at the set on and off times.

Now, when the current time and day of the week are adjusted and the timer time is set as described above, the main control section 22 inputs the time signal from the clock section 21, displays the current time on the current time display section 1, and displays the day of the week. The day of the week is displayed in the section 4, and the on/off determination means compares and determines the current time and day of the week with the on and off times of the same day set in the timer time setting section 10, and determines the result. It is output to the signal output section 23 as a timer output signal. In addition, the output validity determination means distinguishes between when adjusting the current time and day of the week, when setting the timer time, or when recovering from a power outage, and during normal operation other than these, and outputs the result as a timer enable signal. The signal is output to the signal output section 23 as a signal. Furthermore, the main control unit 22 always sends a timer connection signal to the external device to which the timer device is connected, during normal operation after power is applied, to indicate that the timer device is normally connected and operating. , signal output section 23
Output to.

An example of the operation of the main control section 22 will be explained with reference to a timing chart shown in FIG. Note that the valid/invalid switch 13 and the like of the timer time setting section 10 are all set to the "valid" side for the sake of explanation.

In Fig. 3, a shows the time transition, and times T ₁ , T ₃ , and T ₈ are the timer on times, and T ₂ , T ₆ , and T ₉ are the timer off times, respectively. be. Further, FIG. 1B shows the respective states of the timer output signal S ₁ , timer enable signal S ₂ and timer connection signal S ₃ output from the main control section 22.

First, before time _T1 , it is in a normal timer mode, and in this state, both the timer connection signal _S3 and the timer enable signal _S2 are on. On the other hand, the timer output signal _S1 is turned off. Then, at time _T1 , the main control unit 22 determines that the current time and the on time match, and as a result changes the timer output signal _S1 from the off state to the on state. At the same time, the setting display element 17 changes from the off state to the on state. After that, timer output signal S ₁ remains on and transitions to
At time T ₂ , the current time and off time match,
Change to off state.

Then, at time T ₃ on the next day (Tuesday), the timer output signal S ₁ becomes ON again, and as the current time passes, the ON time setting switch 11 and the OFF time setting switch 14 at the timer time setting time 10 are turned ON again. Depending on the set time, the timer output signal changes to an on state or an off state.

Next, assume that a power outage occurs at time T ₄ when timer output signal S ₁ is on, and power is restored at time T ₅ . Naturally, during a power outage, the timer output signal S ₁ , timer enable signal S ₂ , and timer connection signal S ₃ are all turned off. When power is restored, the main control unit 22 first switches on the backup power supply 24.
The current time and day of the week are read from the clock section 21, which was operating even during the power outage, and the on time and off time are read from the timer time setting section 10, and the current time and day of the week are correctly displayed, and the timer connection signal _S3 is turned on. , then set the timer output signal S ₁ to the state before the power outage,
That is, it is returned to the on state.

Next, after time ta (for example, 2 seconds) has elapsed since the timer output signal S ₁ was turned on, the timer enable signal S ₂ is activated.
Turn on. In this way, returning the timer output signal S ₁ earlier than the timer enable signal S ₂ by the time difference ta is useful for external devices that turn on and off equipment by detecting changes in the timer output signal S ₁ . In this case, when the timer output signal S ₁ returns, the timer valid signal S ₂ is still on, so it can be determined that the on state due to the timer on time setting is not the off state. Furthermore, if there is an off time setting between time T ₄ and time T ₅ ,
At this time, the return of the timer output signal _S1 is delayed by the time difference ta compared to the timer valid signal _S2 .

Next, after the timer output signal _S1 is turned off at time _T6 , when the output inversion switch 19 is manually operated at time _T7 , the timer output signal _S1 is turned on. That is, by operating this output inversion switch 19, the timer output signal _S1 can be arbitrarily inverted regardless of the setting in the timer time setting section 10. However, the time shown in Figure 3
When the timer output signal is turned on at _T7 , the timer output signal does not change at the next on time _T8 , continues to be on, and changes at the next off time _T9 .

Furthermore, between time T ₁₀ and time T ₁₁ , the current time
When adjusting the day of the week or setting the timer time, the timer enable signal _S2 is turned off during this time.
Even if the output of the timer output signal _S1 is unstable and inverted as shown by the dotted line in the figure, it can be identified.

Although the operation of the timer has been explained using the timing chart in FIG. 3, if the enable/disable switch 13 of the timer time setting section 10 is
If it is on the side, the on time or off time setting for the corresponding day of the week will be completely ignored as a timer operation.

An embodiment of the weekly program timer device of the present invention has been described above with reference to the accompanying drawings, but in addition to this configuration, the following configurations are also possible.

(1) In FIG. 1, since the timer time setting section 10 is not frequently used for setting operations, it is desirable to provide this section with a releasable transparent cover that does not attach or detach. This cover prevents the set time from being changed inadvertently and prevents dust from adhering to the switch.

(2) The on time setting switch 11 and the off time setting switch 14 in the timer time setting section 10 are
It is possible to integrate the digital switch 12 and the valid/invalid switch 13, or the digital switch 15 and the valid/invalid switch 16.

(3) The enable/disable switch 13 and the like in the timer time setting section 10 may be simplified to one for each day of the week. Furthermore, if a switch is added that can enable/disable all the timer time settings at once, the operability can be further improved.

(4) If the display of the current time display section 1 can be switched to the same 24-hour system as the timer time setting section 10, usability will be improved.

(5) The timer connection signal _S3 can be omitted because it can be replaced with the timer enable signal _S2 depending on the type of external device connected to this timer device, and can be selected depending on the purpose of use. .

Effects of the Invention As described above, the weekly program timer device based on the present invention has a clock section that measures time, a current time display section that displays the current time, a day display section that displays each day of the week, and a time display section that displays the current time. a timer time setting section comprising an adjustment section for adjusting the day of the week; and seven sets of on-time setting switches and off-time setting switches that can respectively set and display the time corresponding to each day of the week;
A main control section comprising an on/off judgment means for comparing and judging the timer setting time with the current time and day of the week, and an output validity judgment means for judging whether or not it is time for adjustment in the adjustment section, and the main control section. It consists of a signal output section that outputs a timer output signal and a timer enable signal to the outside, and a timer time setting section that allows you to set different on and off times for each day of the week for the timer. , each time can be set independently according to the weekly life rhythm of the user of the device, and all set times can be checked at once, making it easy to set the timer time and extremely error-free.
In case the timer output signal becomes uncertain, such as when adjusting the current time/day of the week or setting the timer time,
Since it was configured to output a timer enable signal,
It is possible to improve the reliability of timer operation, dramatically improving operability and stabilizing the operation. Furthermore, it has excellent versatility as an automatic driving control system and can be realized at a relatively low cost.
