All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Examples
The application provides a backlight control system of a remote controller, referring to fig. 1, comprising: the illumination intensity sensing unit is used for acquiring the real-time illumination intensity of the environment where the remote controller is located; the gravity sensing unit is used for acquiring the position change information of the remote controller; the backlight lamp is used for displaying keys on the remote controller; and the control unit is used for receiving the electric signals of the illumination intensity sensing unit and the gravity sensing unit, judging whether the electric signals accord with the backlight on or off condition or not based on the acquired electric signals, and controlling the backlight to be turned off or on based on the backlight on or off condition. The indication lamp is used for displaying the position of the remote controller, and the control unit controls the indication lamp to be turned on or turned off. When the remote controller is used, the position of the remote controller is displayed through the set indicator lamp, so that a user can find the remote controller in a dark environment conveniently. When the remote controller is found, the illumination intensity sensing unit and the gravity sensing unit detect relevant information in real time, and control the backlight to be turned on or off based on the detected information.
Specifically, when the control unit acquires the electric signal of the illumination intensity sensing unit, judging whether the real-time illumination intensity is larger than a set illumination intensity threshold value or not;
when the real-time illumination intensity is larger than the set illumination intensity threshold value, the indicator lamp and the backlight lamp are controlled to keep in a closed state; at this time, the ambient light is relatively large, and the remote controller can be used without an indicator lamp.
When the real-time illumination intensity is smaller than or equal to the set illumination intensity threshold value, the control unit turns on the indicator lamp or the backlight lamp based on the electric signal of the gravity sensing unit.
The control unit is used for judging whether the position change information measured by the gravity sensing unit is larger than a set position change threshold value.
When the position change quantity measured by the gravity sensing unit is larger than or equal to the position change threshold value, the control unit controls the backlight to be started and controls the indicator to be closed. When the position change amount measured by the gravity sensing unit is smaller than the position change threshold value or the key is pressed, the control unit controls the backlight to be turned off and controls the indicator to be turned on. Through this setting, whether detect the user and use the remote controller through gravity sensing unit, when finding that the user contacts the remote controller, gravity sensing unit can detect corresponding signal, at this moment, opens the backlight, throws light on through by the light, and convenience of customers uses the remote controller, improves user's use experience.
Further, the backlight control system further includes a timer, when the backlight is turned on, the timer counts the time when the backlight is turned on, and the initial time of the timer is the time when the position change measured by the gravity sensing unit is less than the position change threshold value or the key is pressed, which can be understood as the initial time being the time when the remote controller is operated last time to cause the backlight to be turned on.
The control unit receives the backlight lamp lighting time value counted by the timer, and when the backlight lamp lighting time value is larger than the set first time threshold value, the control unit controls the backlight lamp to be turned off and controls the indicator lamp to be turned on. When the passing backlight lighting time value is larger than the set first time threshold value, the situation that the user does not operate the remote controller again in the time period can be understood, at the moment, the backlight is turned off, the indicator lamp is turned on, namely the electric quantity of the remote controller is saved to a certain extent, and meanwhile, the indicator lamp can facilitate the user to find the remote controller.
Further, the backlight control system further comprises a sound intensity detection unit, and the sound intensity detection unit is used for acquiring the sound intensity of the environment where the remote controller is located.
The control unit receives the electric signal of the sound intensity detection unit and controls the sound intensity detection unit.
When the control unit judges that the real-time illumination intensity is smaller than or equal to the set illumination intensity threshold value, the sound intensity detection unit is started, and otherwise, the sound intensity detection unit is closed. When the illumination intensity is smaller than or equal to the set illumination intensity threshold, the peripheral light of the remote controller is darker at the moment, and at the moment, the sound intensity detection unit is started and used for detecting the sound around the remote controller. When the illumination intensity of the surrounding environment of the remote controller is high, the sound intensity detection unit is turned off.
The timer counts the time when the indicator lights are turned on, and the control unit controls the indicator lights to be turned on or off based on the sound intensity detected by the sound intensity detection unit when the time when the indicator lights are turned on is greater than a set second time threshold.
Specifically, the control unit receives the sound intensity detected by the operation detection unit and compares the sound intensity with a set sound intensity threshold.
And when the time for the indicator light to light is larger than the set second time threshold and the detected sound intensity value is smaller than the sound intensity threshold, the indicator light is turned off, and otherwise, the indicator light is kept in an on state. After the indicator light is turned off, the indicator light is turned on if the detected sound intensity value is greater than or equal to the sound intensity threshold.
It should be explained that, when the illumination intensity is less than or equal to the set illumination intensity threshold, the indicator light will be turned on at this time, that is, the condition that the indicator light is turned on for the first time is that the illumination intensity is less than or equal to the set illumination intensity threshold. And counting time through a timer after the indicator light is turned on, and if the user is not found to operate the remote controller, at the moment, when the counted time of the indicator light is larger than a second time threshold value and the detected sound intensity value is smaller than the sound intensity threshold value, turning off the indicator light. The condition that the indicator light is turned on again is that the detected sound intensity value is greater than or equal to the sound intensity threshold value, or the indicator light is turned on due to accidental touching of the remote controller, and the indicator light is also turned on when the indicator light is turned off.
