Abstract

PURPOSE:To execute a start operation by an arbitrary operation when a power supply switch is next turned ON by setting the start operation at the time of power source ON separately from a last operation at the time of power source OFF. CONSTITUTION:The queuing device is composed of a power supply plug 1, an entire power supply circuit 2, a standby power supply circuit 3, a sub power supply switch 4, a microprocessor 6, an EEPROM 7, a local key group 8, a remote control receiver 9, a power supply terminal 10 and a key reception display device 11. In the state of the power supply switch 4 is being turned OFF, the start operation at the time of turning on the next power supply switch is stored in the EEPROM 7. Thus, even when the power source is turned OFF at the night in the state of decreasing the volume, the operation can be started on the next day with the volume level increasing the volume corresponding to the surrounding environment by turning ON the power source.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides electrical equipment such as television receivers,
The entire device is a standby device that maintains the main device in a standby state with a standby power supply that constantly generates power supply voltage using an Ili source, and allows the start operation to be set to any desired operation when the next power switch is turned on. be.

(Conventional technology) Electrical equipment such as television receivers must be turned on when the power switch is turned on.
Even in the FF state, the device usually has a standby function that sends a power supply voltage from a standby source using the entire power source of the device to the built-in microprocessor and accepts a key command to turn on the power. After the power is turned on by the standby function, the start operation starts from the last operation when the power switch was turned off.

That is, for example, in a television receiver, the volume level and reception channel from the previous use are memorized, and the next time the power is turned on, it starts in these operating states. The operating state at the time of last use is, for example, EEPROM (electrica
lly erasable read only me
g+ory) or stored in memory means backed up by a dry cell battery. There is no need for the user to consciously memorize this last action;
This is automatically performed when the operating state is changed in the N state.

Figure 7 shows the dimensions of the system that performs the above standby operation.

In the figure, 41 is the main device, and 42 is a remote control for controlling the main device 41. The main unit "jS41" has power plug 4
A power supply voltage is generated from a general power supply circuit 44 and a standby power supply circuit 45 using a commercial AC power supply from 3. The power supply voltage from the overall power supply circuit 44 is applied to each block via a so-called sub-power switch 46 (hereinafter simply referred to as a power switch) for power ON/OFF. The power supply voltage generated from the standby power supply circuit 45 is supplied to the microprocessor 4.
7 as a power supply voltage. This results in
The microprocessor 47 is adapted to accept the power-on key command among various key commands even in the power-off state where no power supply voltage is applied to each block (standby function). That is, microprocessor 4
7 is a local key group 48 attached to the main device 41;
Commands based on the power key and remote control receiver 4
The power ON command from 9 is processed when the power is turned OFF, and the power switch 46 is turned ON.

Furthermore, an EEPROM 50 whose stored contents are not lost even when the power is turned off is connected to the microprocessor 47. The EEPROM 50 automatically stores the last operation when the power was previously turned off, and after the above power is turned on,
The device main body 41 can be operated with the stored last operation.

Note that the remote control 42 also has a built-in microprocessor 51, and the microprocessor 51 is connected to the matrix key group 52.
The remote control light emitter 53 processes the key commands and sends out a transmission signal based on the key commands.

Conventional standby devices like this do not turn on the power when the power is off.
It will be ready to accept key commands, and the power will be turned on.
If N is selected, the operation starts with the operation stored in the non-volatile memory immediately before the previous power-off.

However, the start operation setting method of such a standby device is
For example, if you were watching at a low volume late at night, turn it off.
Then, when you turn on the power the next day during the day, the noise is usually louder so you have to turn up the volume. In addition, in devices such as CD devices with tuners, "PL
If the CD function is turned OFF in the AY'' state, the next time the power is turned ON, the CD function will be ON, and if you want to select the tuner, you will have to perform a key operation to select tune.

(Problems to be Solved by the Invention) As described above, in the conventional standby device described above, when the power is turned on, the operation starts from the operation when the power was turned off.
It was not possible to start from the user's desired behavior in response to environmental changes.

SUMMARY OF THE INVENTION In view of the above problems, the present invention aims to provide a special V device that allows the start operation to be selected when the power is turned on.

[Structure of the Invention] (Means for Solving the Problems) The present invention stores an operation based on a specific key command in addition to the last operation in a memory that stores the last operation when the power is turned off, and stores the operation based on a specific key command when the power is turned on. The present invention is characterized in that a start operation selection means is provided for starting the device from an operation based on a specific key command, giving priority to the last operation.

(Function) According to the present invention, when the power switch is turned off or turned on,
During operation, a start operation can be specified for the next time the power switch is turned on.

For this reason, for example, at night when the volume is lowered and the power is turned off to 0F,
FL, but when you turn on the power the next day, it will start with the volume increased according to the surrounding environment, and there is no need to re-manage the operating state.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a standby device according to the present invention.

FIG. 1 corresponds to the main body of the device in FIG.

1 is an AC plug, and commercial AC power from the AC plug 1 is supplied to the overall power supply circuit 2 and the standby power supply circuit 3. The overall power supply circuit 2 generates the power supply voltage necessary for each block from a commercial AC power supply. Power supply voltage from the overall power supply circuit 2 is supplied to each block via a power switch 4 constituted by a relay or the like. The standby power supply circuit 3 obtains a DC voltage of, for example, 5 cm from a commercial AC power supply, and keeps the microprocessor 6 in an operating state even when the power switch is OFF.

The microprocessor 6 includes a non-volatile EEPR.
When the OM 7 is connected, signals from the local key group 8 and remote control receiving device 9 attached to the main device are input. Is the microprocessor 6 a local key when the power is turned off? :18 and the signals from the remote control receiving device 9, only the key command for turning on the power is accepted, and a signal for turning on the sub power switch 4 is generated. When the power is on, various key commands including the power key are sent to each block or the power switch 4. EEPRO
In M7, the state changed by a specific command is stored each time, and as a result, the state indicating the operation immediately before the power supply O is stored, and when the power is turned off, the state changed by the local key group 8 and the remote control receiving device 9 is stored. Changes in status caused by specific keys sent out (commands meaningful as a start operation when the power is turned on) are stored.

Note that a key reception display 5A 11 is connected between the microprocessor 6 and the power supply terminal 10. The key acceptance display device 11 is controlled by the microprocessor 6, and lights up when there is a key input.

According to such a configuration, when the power switch 4 is in the OFF state, the start operation for the next power switch ON can be stored in the EEPROM 7. Therefore, even if the power is turned off at night with the pitch lowered, the next day when the power is turned on, the volume will start at an increased volume level that corresponds to the surrounding environment.

FIG. 2 is a chart showing the operation of the microprocessor 6 in the above device.

In FIG. 2, during normal operation when the power is turned on, a loop of steps S1→S2→S3→S4→S1 is repeated.

When the power is OFF, steps S1→S2 are performed by pressing the local key J! Signal input based on manual key operations from ¥8 and remote control receiver @9 is monitored.

If it is determined in step S2 that the key is powered (Yes), step S3 is executed, and the state (flag) of the power switch 4 is determined.In this case, the power switch is turned OFF.
Therefore, proceed to step 5.

Step S5 is a process of determining the type of key human power. This is to select a meaningful command as the start operation when the power is turned on. For example, in a previsicon receiver, the channel up/down command is
Channels do not change immediately after turning on the power. Further, in a CD device or the like, the key command for program search is meaningless unless a disc is set.

In step S5, NO is output in the case of a key command that has no meaning as the start operation, and Yes is output in the case of other commands such as volume up/down, channel number designation, audio mute, or power ON. If NO, the process returns to step S1 without performing any processing.

In other words, ignore that key command.

Now, in the case of Yes in step S5, step S6 is performed. Step S6 stores the key command based on the specific key in the EEPROM 7. When the specific key command is stored in the EEPROM 7 in this way, the power switch 4
When a command to turn on is input, the main device executes a loop from steps 81 to S◆, and starts operating at the channel number or volume specified when the power 11i is turned off. In this case, the number of commands that can be specified is
It may be one or more. Further, whether a command has been designated or not can be confirmed by the key acceptance display device 11.

FIG. 3 shows the surface of the remote control transmission keypad in the case of the embodiment shown in FIG.

In FIG. 3, the Nll1 key 13, numeric keypad 14, mute key 15, volume key 16, and channel up/down key 17 marked with * are commands that are meaningful when designated as the start operation when the power is turned on.

By simply pressing these keys in the same way as when turning on the power, the operations based on these keys will be stored in the EEPROM 7. In addition, key reception display device 1
1 may be displayed only when an input is made using the above-mentioned specific key.

Next, another embodiment will be described.

FIGS. 4 and 5 show another embodiment of the present invention, in which a start command can be stored in the EEPROM even when the power is turned on normally.

That is, FIG. 4 shows the present invention applied to the system shown in FIG. 7, and FIG. 5 shows the surface of the remote control key pad in that case. Blocks with the same functions as in FIG. 7 are given the same reference numerals. The configuration of FIG. 4 differs from that of FIG. 7 in that the remote controller 42 is also provided with a non-volatile EEPROM 20, and the start operation is stored in the EEPROM 20 on the keypad surface of the remote controller 42 in correspondence with the above memory means. A start operation registration key 18 for (registration) and a registration operation cancellation key 19 for canceling the registration are provided.

According to the embodiment described above, during normal operation with the power supply 111 turned on, it is possible to memorize the start operation for the next time the power supply is turned on. In the embodiment shown in FIG. 1, the start operation when the power is turned on is stored when the power is turned off. Power on
Sometimes, in order to be able to memorize the start action, a key that is distinct from normal key commands is required. Therefore, as shown in FIG. 4 (FIG. 5), a start operation registration key 18 and a registration release key 19 are provided, and the start operation registration key 1
For the key group (13 to 16) pressed in combination with 8, the key commands are registered in the EEPROM 20 as start commands. By registering the start operation in this way, the operation is started from the command of the specific key registered by the registration key 18, giving priority to the last operation stored in the EEPROM 20 immediately before the power is turned off.

FIG. 6 shows a flowchart of the above embodiment.

In FIG. 6, step Sll→S 12→813→
The So loop is an operation when the power is turned off. Also, step So→S 12→813→814→Sts→S1
Loop 1 indicates normal operation when the Wi source is turned on.

If the result in step 814 when the power source is turned on is Yes (start operation registration key manual and specific key manual), the command based on the specific key is stored in the EEPROM 20 as a start command in step S+s.At this time, the power supply is turned on. Memorize so that ON command has priority.EE
When the above start command is input to PROM20,
When the power is turned on next time, a loop of steps 81 to S15 is executed, and the operation can be started at the channel number or volume specified when the power is turned off, as in the previous embodiment.

When changing the type of registered start operation, a step of determining whether or not the release key 19 has been input may be set after step S16.

J5, start operation registration key 18, and release key 19 can also be provided on the main device 41 side. Further, the registration operation is possible even when the power is turned off, similarly to the embodiment shown in FIG.

[Effects of the Invention] As described above, according to the present invention, the start operation when the power is turned on can be set separately from the last operation when the power is turned off, and can be freely changed.
