Abstract

PURPOSE:To cope with the change of only specific time and date by providing a means to skip temporarily a specific set time point in a repeating cycle for each prescribed period. CONSTITUTION:An automatic power supply controller turns on and off a power supply device with the control signal outputted from a power supply control interface part 7 and is provided with a microprocessor MPU1, an operating part 8, etc. A schedule is written previously to a memory 4 from the part 8. In such a case, a skip switch 8' is added to output the data for skipping a set time point of a prescribed data together with a register 9 which stores the data delivered from the switch 8'. Based on the data stored in the register 9, the data on the prescribed time and data, etc. read out of the memory 4 by the MPU1 are skipped temporarily to prevent the ON/OFF control. The MPU1 clears the register 9 after once readin the data of the register 9 and reset the original schedule at and after the next time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic power supply control device that controls on/off of a power supply device that supplies power to a predetermined device at a set time.

With the expansion and development of information processing devices, various terminal devices connected to information processing systems have come into use.

Depending on the usage situation, these various terminal devices may have
There are many devices that use the device only during a set time period and do not use it at other times.

In such a case, an automatic power control device controls the on/off of the power supply built into the terminal so that it can be used only during the set time period.

The aim is to reduce current consumption and ensure safety.

In such on/off control of the power supply device.

There is a need for a practical control method that can flexibly respond to temporary changes in the set time zone.

[Conventional technology]

Fig. 2 shows a conventional automatic power control bag W (hereinafter referred to as APC), (A) is a block diagram, and (B) shows the control time setting 19. Fig. 3 shows the configuration of the operation surface of the APC.

In this example, the power supply of a device that does not need to be energized all the time and is used only during usage hours is turned on/off by a control signal output from the power supply control interface section 7, and the power supply is turned on/off according to the control signal output from the power control interface section 7. For example, as shown in FIG. 2(B), the vehicle schedule is set for one week, and automatic control is performed according to the set schedule.

The above schedule can be created by operating the operation unit 8, for example, to create a weekly schedule in memory (RAM) using data output from the calendar unit 3 and the switch unit 5.
Written to 4.

The contents written to the memory (RAM) 4 are 2. For example, as shown in Figure 2 (B), there is no control on Sunday 1.
o: oo on, 00:00 off, Monday to Friday, AM8:00 (08:00) on,
PM5: 00 (17200) off, Saturday is A
M8:00 (08:00) On.

PM 1:00 (13:00) Off is written.

In this state, the control program in the memory (ROM") 2 causes the microprocessor (hereinafter referred to as MPU) 1 to calculate the day of the week output from the calendar section 3.

Memory (RAM) for the control time period corresponding to that day of the week
4 and outputs a control signal via the power supply control interface section 7.

The operation section 8 of the APC is constructed as shown in FIG. 3, where the circle indicates the display section and the two ports indicate the switch section. The display section 6 also controls the display of the O section. - To write to memory (RAM) '4, press the mode switch m to the set switch, and first set the "hour" switch h to 002 "minutes" as the Sunday control on time.
Set switch j to 00. Similarly, as the off time, the "hour" switch h is set to OO and the "minute" switch j is set to OO.

Next, as the control on time for Monday, September 9, set the "hour" switch h to 08. Set the "minute" switch j to 00, and similarly set the "hour" switch h to 17 degrees and the "minute" switch j to 00 for off time. Use this setting method to set the on/off times until Saturday.

In the case of normal control according to the above schedule, 2
For example, if you want to disable on/off control because Tuesday is a holiday, conventionally, you would cancel the set time for Tuesday by using clear switch n by the day before that day, so that on/off control would not be performed. Once completed, the original time zone settings would be set again on Wednesday morning, for example.

It is assumed that a backup power source (not shown) is provided for the memory (RAM) 4 to which voltage is supplied even when the power is turned off.

[Problem that the invention seeks to solve]

In the above case, if you forget to cancel the preset time before the holiday, the power will be turned on needlessly. Furthermore, if the user forgets to reset the original time after a holiday ends, the power will not be turned on, which may hinder business processing.

[Means for solving problems]

The present invention aims to realize a new automatic power supply control device that solves the above-mentioned problems. The automatic power control according to the present invention is provided with a means for skipping at the set time, and the means temporarily skips the power on/off at the set time, and performs power on/off control at the original set time in the first cycle. The problem is solved by the device.

[Effect]

That is, a skip switch that outputs data for skipping the set time of a predetermined date and time, and a register that stores the data output from the skip switch are provided, and the data stored in the register is read from memory (RAM) by the MPU. The data at the specified date and time is temporarily skipped, and on/off control is not performed.

Also, once the data stored in the register is read by the MPU, MPLI clears the register and returns to the schedule written in memory (RAM) from the second time onward, ensuring that changes only to a specific date and time can be handled. possible.

〔Example〕

The gist of the present invention will be specifically explained below with reference to an embodiment shown in FIG.

FIG. 1 shows an embodiment of an automatic power supply control device according to the present invention. The same symbols indicate the same objects throughout the figures.

In this embodiment, it is assumed that power on/off control of a device (such as a terminal device, etc.), not shown, is performed by repeating a weekly schedule. In such a situation, for example, if Tuesday of the second week of the month is a holiday and the on/off control of the power supply (not shown) is no longer required, the next action must be taken by the Monday of the second opening. I do.

That is, by pressing the skip switch 8' provided on the operation unit 8 and the Tuesday switch C shown in FIG.

Next, when the MPUI reads the set time for Tuesday from memory (RAM) 4, the MPUI compares it with the skip data from register 9, skips the read set time data for Tuesday, and sets ' to the source (not shown). ) on/off control.

Next, the MPUI outputs a reset signal to register 9, clears the skip data stored in register 9, and
On Tuesday of the third week, on/off control is performed according to the data read from the memory (RAM) 4.

〔Effect of the invention〕

According to the present invention as described above, even if a special date and time is inserted in the middle of a regular schedule, it can be easily and reliably handled.
