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 operation 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 to set the on/off time for each day of the week. (a) Types in which a series of on/off operations are input using a reading device using a mark sheet, etc.; (←・) Types in which on/off times are set by a combination of a keyboard, CRT, host computer, etc. There were things to display, etc.

Problems to be Solved by the Invention Among 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. However, in order to check the on/off time settings between -a, key operations are always required, and it is difficult to grasp the overall operation.

In the case of (g) and (c), although extremely complex on/off operations are possible, the cost of the equipment is extremely high, and furthermore, it requires considerable specialized knowledge or skill to handle it. However, there are some drawbacks in terms of ease of operation.

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

Means for Solving the Problems In order to solve the above-mentioned problems, the weekly program timer device of the present invention has a clock section that measures the time, a current time display section that displays the current time, and a display section that displays each day of the week. A day of the week display section, an adjustment section for adjusting the current time and day of the week, and an on time setting switch and an off time setting switch that can set and display the time for each day of the week displayed on the day of the week display section. A timer time setting section consisting of seven sets, a main control section that compares and judges the timer setting time against the current time and day of the week and issues a timer output signal, and a main control section that inputs the timer output signal from the main control section and outputs it to the outside. It is configured by a signal output section that outputs a signal.

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, making it possible to set each time independently and displaying all set times at all times. By providing a timer time setting section that can be used to set a timer time, the conventional problems are greatly improved.

Operation The present invention has the above-mentioned configuration, particularly the timer time setting section, which allows
Different on and off times can be set independently for each day of the week for the timer over a week, and all set times can be checked at once, making it easy to set the timer time and prevent mistakes. Operability can be dramatically improved by allowing fewer operations to be performed. 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.

Embodiment Hereinafter, a weekly program timer device according to an embodiment of the present invention will be described 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. FIG. 2 is a block diagram of the embodiment of FIG. 1.

First, in FIG. 1, reference numeral 1 denotes a current time display section, which includes a light emitting element 2 for displaying AM/PM, a numeric display element 3 for displaying 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;
One of the 1 @ lights up and 7 indicates the day of the week. Reference numeral 6 denotes an adjustment section for adjusting the current time and day of the week, which includes an adjustment set switch 7, an hour/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. It is comprised of an enable/disable changeover switch 13 for selecting whether to disable or disable. Similarly, the off time setting switch 14 is composed of a digital switch 15 and a valid/invalid changeover switch 16. 17 is
In the timer time setting section 10, this is a setting display element that lights up to indicate that the ON time or OFF time setting is being changed.

18 is a timer output display element for displaying the on/off state of the timer output signal output from this timer device; 19
is an output inversion switch for arbitrarily inverting the state of this timer output signal by manual operation.

Next, in FIG. 2, 20 is 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 is a main control unit which is configured by a microcomputer, is connected to each part of this timer device, and supervises and controls their operations, and 23 is a main control unit which transmits timer output signals etc. issued by the main control unit 22 to external devices. This is a signal output section that outputs signals.

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. Power is supplied to a portion of the memory to continue the timekeeping operation and to cope with the power restoration operation.

Next, the operation will be explained.

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

Once the adjustment set switch 7 of the adjustment section 6 is pressed, the main control section 22 detects this and enters the hour/minute/day adjustment mode. Then, operate the hour and minute adjustment switch 8 to adjust the current time displayed on the current time display section 1, and adjust the day of the week adjustment switch 9.
to match the day of the week displayed on the day of the week display section 4.
When the adjustment set switch 7 is pressed again, the hour, minute, and day adjustment mode is completed. 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 bank-up power supply 24 allows the timekeeping unit 21 to continue counting for a predetermined period of time (for example, 24 hours), and a part of the memory of the main control unit 22 is also stored as before the power outage. In order to continue saving the data of the main controller 2, once the DC power supply 20 is restored,
2, the time data of the timer 21 can be read and the normal state can be restored.

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

To set the on time and off time for each day of the week between J, the on time setting switch 11 and off time setting switch 1 corresponding to each day of the week in the timer time setting section 10
Operate the adjustment lever of the digital switch 12.15 provided at 4.

This adjustment lever has a rotary structure, and each of the four digit numbers can be set independently, and the desired on time and off time can be set by manually operating the adjustment lever.

On the other hand, the main control section 22 always 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. If the on time or off time is incorrectly set, for example, 3:65 p.m., set it as a 24-hour time! /-1 #f setting blinks the light-emitting element 5 for displaying the day of the week corresponding to the on-time frequency 1kan9unwitch 11 or off-time setting switch 14 of the tree soup, which is incorrect. Let me know. 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 more than a predetermined time (for example, 3 seconds), it is automatically assumed that the timer time setting has been completed, and the display element 1 during setting
7 and completes the timer setting mode.

Oh, like this, the digital switch 12.1 is set for each day of the week.
If you do not want to run the timer automatic operation regardless of the on time and off time set in 5. For example, if you normally run the timer automatic operation every day throughout the week, but temporarily do not want the timer operation to run for one day, you need to respond accordingly. If the valid/invalid selector switch 13 or 16 is set to the "invalid" side, the on time or off time will be ignored and the timer operation will be delayed. If the setting of the effective/unassisted changeover switch 13.16 is returned to the "effective" side, the timer operation can be performed at the set on time and off time.

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, and displays the current time on the current time display section 1.
The day of the week is displayed on the day of the week display section 4, and the current time and day of the week are compared with the on time and off time of the same day set in the timer time setting section 1o, and the result is output as a timer output signal to the signal output section. Issued on the 23rd.

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 timer time setting section 1
o's enable/disable switch 13, etc. are all "
Set to "valid" side. Fig. 3 (al indicates the time transition; times T1, T3, and T8 are the on times of the timers, respectively, and T2, T6, and T9 are the off times of the timers, respectively. The state of the timer output signal output from the main control section 22 is shown.

First, 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 from the off state to the on state. At the same time, the setting table hydrogen element 17 changes from being off to being on. Thereafter, the timer output signal remains in the on state, and at time T2, the current time and the off time coincide, and the timer output signal changes to the off state.

Then, at time T3 on the next day (Tuesday), the timer output signal turns on again, and as the current time passes, the on-time setting switch 11 of the timer time setting section 10
and according to the set time of the off time setting switch 14,
The timer output signal changes to an on state or an off state.

Next, at time T4, a power outage occurs while the timer output signal is on, and when the power is restored at time T5, the main control section 22 uses the back amplifier power supply 24 to control the clock section 21, which had been operating during the power outage. The timer time setting unit 10 reads the current time and day of the week, the on time and the off time, and displays the current time and day of the week correctly, and returns the timer output signal to the state before the power outage, that is, to the on state.

When operated manually, timer output No. 1 is inverted to the on state. That is, by operating the output inversion switch 19, the timer output signal can be arbitrarily inverted regardless of the setting in the timer time setting section 10. However, when the timer output signal is turned on at time T7 in Fig. 3, 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. Become.

Although the operation of the timer has been explained using the timing chart shown in FIG. The on time or off time setting of the timer is 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 does not usually require complicated setting operations, it is desirable to provide this section with a detachable or releasable transparent cover. This cover prevents the set time from being changed inadvertently.
This has the effect of preventing dust from adhering to the switch section.

(2) The on time setting switch 11 and the off time setting switch 14 in the timer time setting section 10 are connected to the digital switch 12 and the valid/disable changeover switch 13, and the digital switch 15 and the valid/invalid changeover switch 16.
It is possible to have a configuration that integrates both.

(3) The valid/invalid switch 13 and the like in the timer time setting section 10 may be simplified to one for each day of the week.

Further, by adding a switch that can collectively enable/disable the timer time setting section, the operability can be further improved.

(4) Change the display of the current time display section 1 to the timer time setting section 1.
If it is printed so that it can be switched to the same 24-hour system as 0, it will be easier to use.

Effects of the Invention As described above, the weekly blogger timer device according to the present invention has a clock section that measures time, a current time display section that displays the current time, and a day of the week display section that displays each day of the week. An adjustment section for adjusting the time, minute, day of the week, a timer time setting section having seven sets of on-time setting switches and off-time setting switches that can set and display the time corresponding to each day of the week, and the current time and day of the week. It consists of a main control section that compares and judges the timer setting time against the main control section, and a signal output section that outputs the timer output signal from the main control section to the outside. Set different on and off times for each day of the week for the timer.
Since each timer can be set independently and all set times can be set in mW at once, it is easy to set the timer time and there are extremely few errors, dramatically improving operability, as well as automatic driving control. It has excellent versatility as a system and can be realized at relatively low cost.
