Description

Super low power control method

The present invention relates to a remote control power saving control method for preventing unnecessary power waste in a remote control device used for remote control of a television or a television.

In recent years, most V-TVs or TVs are equipped with a remote control unit and an OSD (On Screen Display) function, which are displayed on the monitor screen when the color adjustment, channel memory, or current time are set from a distance without accessing V-Cal. It is possible to operate easily while looking at the characters.

For example, by setting the on-time and off-time programs of the television through the remote control method and the OSD method, the TV viewing time may be determined in advance, or unnecessary TV on state when the user falls asleep while watching TV using the TV off-time. In addition, the television on time can be used to obtain a function as an alarm clock for the morning weather.

However, since the remote control device of the home appliance is designed under a constant power supply condition using a battery as an operating power source, unnecessary power consumption is inevitable.

Therefore, the present applicant has previously proposed a technique for preventing unnecessary power consumption in the remote controller, and the technical contents thereof will be described below.

1 is a circuit configuration diagram of a remote controller to achieve power saving in a remote controller according to the present invention. The remote controller micom 10 for controlling the operation of VSI is provided with a timer circuit 14 and a key input circuit 11. Is connecting. The timer circuit 14 will provide time information to the microcomputer 10 side.

The key input circuit 11 cuts the part of the remote control keypad having basic key input buttons such as the ten (0 to 9) keys and the channel up / down keys.

The output of the microcomputer 10 is connected to be provided as remote control information on the display circuit 13 via the drive circuit 12.

In addition, the power supply circuit 15 for supplying the operating voltage to the microcomputer 10 is connected to the power supply is limited by the keypress recognition information by the microcomputer, and the remote control key input signal processed by the microcomputer is IR conversion circuit 16 Is connected to the IR receiving window on the VSI side via the IR diode 17.

The operation of the prior art executed in the remote controller circuit configured as described above will be described in detail with reference to FIG.

First, a reservation recording of a specific broadcast program is set or registered by a VSI user, or a key button provided on the remote controller is pressed to select a function of a VSAL, which is applied to the microcomputer 10 through the key input circuit 11. It is processed and converted into an infrared stream in the IR transformation circuit 16 and sent out through the infrared diode 17 to the IR receiving window which is normally installed on the front side of VSI.

At this time, the microcomputer 10 determines whether there is a key press from the key input circuit 11 as the first step.

When the key press is recognized in the step, the microcomputer determines whether the corresponding key is toggled (restored).

If the corresponding key is toggled, the microcomputer accepts the function corresponding to the pressed kit value as a normal value and outputs the data to the IR conversion circuit 16 so that the converted function selection or adjustment signal is passed through the infrared diode 170. It is sent to the remote control reception window on the VSI main body side.

However, if it is determined that there is no toggle in the determination step of pressing or releasing the pressed key, the microcomputer reads the time value from the timer, executes a timing count, and executes a step of comparing the timing count value with the set time value.

If the current timing count value does not reach the set time in the comparison step between the timing count value and the set time value, the process returns to the determination step of whether to toggle the previous key button. If the timing count time value and the set time value match, the microcomputer It is determined that the remote control key button is pressed by a heavy object due to the carelessness of the user, or that the pressed key button is not restored due to a mechanical defect, and outputs a remote control power supply cutoff control signal to the power circuit 15.

Therefore, even if the remote control is kept pressed by any user's negligence or mechanical failure on the key button, the power supply to the remote control system is automatically turned off, thereby eliminating the possibility of damage to the remote control circuit in addition to the battery power save.

However, the prior art as described above can provide a power save effect under the unavoidable condition of the remote control battery as a countermeasure against the key press phenomenon of the remote control, but it does not save power consumed even when not in use by the remote control. have.

And converting the corresponding key input signal into an IR signal for remote transmission and checking the remaining battery level to determine whether the remaining battery level is a warning condition, and if the remaining battery level is a warning condition, remotely outputs a warning on-screen message. Determining whether the current count value corresponds to a valid input time after executing a timer count reset and start-up; and in this step, the count value corresponding to a valid input time is determined. When it reaches to return to the initial battery power saving mode to determine whether the key input, the above valid key input If the key input time interval exceeds the effective key input time in the determining step whether the time is within the time range, turning on the remote controller and determining whether subsequent key inputs are performed; If there is no key input, IR conversion output is outputted, and if there is no key input, it is a remote control power save method.

Figure 3 is a circuit diagram of the internal hardware of the remote control device for the implementation of the present invention.

As referred to herein, the remote controller micom 10 for controlling the operation of VSIal includes a timer circuit 14 for timing an automatic off point of the remote controller power and a key input circuit 11 for receiving and processing user key input. ).

The key input circuit 11 includes a remote controller keypad portion having basic key input buttons such as the ten (0 to 9) keys and channel up / down keys.

In addition, the output of the power supply circuit 15 for supplying the operating voltage to the microcomputer 10 is connected to the output via the switch circuit 18, the remote control key input signal processed by the microcomputer is IR through the IR conversion circuit 16 The diode 17 is connected to be sent out to the IR receiving window on the VSI side.

In addition, the output of the switch circuit 18 is detected by the voltage detection circuit 19, and when a low voltage is generated is remotely transmitted to the television via the IR conversion circuit 16 to connect the on-screen warning message to the screen of the television. .

If described in detail with reference to Figure 4 the operation of the present invention carried out in such a remote control circuit as follows.

First, the power supply circuit 15 supplies the power of the battery to the key input circuit 11 side and the switch circuit 18 side in the power saving mode. In this state, if there is a key input by the user of the remote control, the key input signal is a microcomputer. Is applied to (10).

Based on this, the microcomputer executes a step of determining whether a key is input.

In the step, if there is a key input, a step of determining whether or not it is within a valid key input time range is executed.

If the key input time is within the effective key input time range, i.e., the power is supplied from the switch circuit 18, the corresponding key input signal processed by the microcomputer is converted into an infrared signal by the IR conversion circuit 16 and the IR element 17. Remote transmission to the remote control receiving window of a television or VSI is performed.

Following this process, the voltage of the battery generated in the switch circuit is checked by the voltage detection circuit 19 to determine whether the remaining battery condition is a warning condition.

In the above battery level checking step, if the warning condition is reached, the control signal for generating the warning on-screen message through the television screen is remotely output, and the current count value is valid after executing the timer count reset and start-up. The method may determine whether the count value corresponds to the count value.

In this step, when the current count value reaches a count value corresponding to the valid input time, the process returns to the initial battery deep sleep mode and determines whether a key is input.

On the other hand, if the key input time interval exceeds the valid key input time in the step of determining whether the key is within the valid key input time range, the remote controller is turned on and a subsequent key input is determined.

In the determination step of the above key input, if there is a key input, the corresponding key input is IR converted and outputted, and if there is no key input, it returns to the step of resetting the timer count. If there is no other key input within the time, the remote enters the deep sleep mode and waits.

As described above, the present invention is not limited to only the remote control for VSI, so it will be apparent that the present invention can be applied to all remote control devices including a remote control for remote control of audio or television.

When the remote control of the present invention is left unused for a long period of time, it enters the ultra-low power mode and waits, thereby significantly preventing the power consumption of unnecessary operation batteries, thereby significantly extending the life of the remote control and the battery life embedded therein. The unique effect is that it will appear.
