in an embodiment, referring to fig. 2, the present invention provides a remote controller backlight adjustment method, applied to a remote controller, where the remote controller is provided with remote controller keys and a backlight, and the remote controller is used to remotely control the backlight so that the remote controller adjusts the backlight, and the remote controller backlight adjustment method includes the following steps:
step S10, when the triggering operation of the remote controller key is detected, determining the target pulse voltage value of the backlight lamp;
step S20, adjusting the driving voltage value of the backlight according to the target pulse voltage value, so that the backlight continuously emits light at a preset brightness in response to the triggering operation.
The execution main body of the embodiment is a remote controller, and the remote controller can be a remote controller of electronic equipment such as a television, an air conditioner and the like. The remote controller is provided with a display screen for displaying the control parameters input by the remote controller. The remote controller can be a physical key remote controller, and the electronic equipment is controlled by pressing a physical key to send a code; the remote controller can also be a touch screen key remote controller, a touch key is arranged on a display screen of the remote controller, and when the touch key is detected to be touched by a user on the display screen, the remote controller is controlled to send a code so as to control the electronic equipment. The remote controller is an infrared remote controller, and the remote controller sends an infrared signal based on a carrier wave of 37.8kHz when sending codes.
in this embodiment, after the remote controller is powered on, the voltage AD starts to be detected, and the period for detecting the battery voltage is to detect a group of voltage AD values every 1 second, where each group includes 8 detections with a time interval of 50 us. In the process, when a user operates the remote controller, the triggering operation of the remote controller key is judged to be detected, and if the user presses the remote controller key, the triggering operation of the remote controller key is judged to be detected; or when the user touches the touch key on the display screen, judging that the triggering operation of the remote controller key is detected.
when the triggering operation of a remote controller key is detected, determining a target pulse voltage value of a backlight, wherein the target pulse voltage value can be a preset fixed value, and if the driving voltage of the backlight is set to be N volts, the N volts specifically provide the N volts to the backlight according to the corresponding voltage value under the condition that the backlight normally emits light and maintain the N volts to emit light, the light provided by the backlight is continuously at a fixed brightness, so that the backlight is prevented from flickering when the key emits a code.
alternatively, the target pulse voltage value may be determined in real time according to the brightness of the backlight lamp when the trigger operation of the remote controller key is detected and before the code is transmitted. As described with reference to fig. 3, the step of determining the target pulse voltage value of the backlight includes:
S11, acquiring first brightness of the backlight lamp when the triggering operation of the remote controller key is detected;
And S12, determining the target pulse voltage value of the backlight lamp according to the first brightness.
the method comprises the steps of determining a target pulse voltage value of a backlight according to first brightness, and when the backlight emits light with the target pulse voltage value, realizing that the backlight brightness is consistent with the backlight brightness before the code emission of the remote controller, and avoiding flicker.
Alternatively, the target pulse voltage value may also be determined according to the electric quantity of the battery. As shown in fig. 4, the step of determining the target pulse voltage value of the backlight includes:
s13, detecting a first voltage value of a battery of the remote controller when the triggering operation of the remote controller key is detected;
and S14, determining the target pulse voltage value of the backlight lamp according to the first voltage value.
The remote controller is provided with a voltage detection module for detecting a voltage value of a battery in real time, if a key of the remote controller is pressed and the remote controller needs to send a code, a large amount of voltage needs to be output at the moment of sending the code, so that the voltage of a backlight lamp is pulled down, in order to prevent the problem that the voltage of the backlight lamp is pulled down to cause the backlight lamp to flicker, the target pulse voltage value of the backlight lamp needs to be distributed to maintain the brightness of the backlight lamp, however, when the key of the remote controller is triggered, the electric quantity of the battery of the remote controller is different, and the pulse voltage value capable of being distributed to the backlight lamp is different.
After the target pulse voltage value of the backlight is determined, the driving voltage value of the backlight is adjusted according to the target pulse voltage value, when the remote controller drives the backlight to emit light according to the driving voltage value, the backlight can continuously emit light at preset brightness when the remote controller responds to the triggering operation of the key, wherein the preset brightness is the same as or similar to the brightness of the backlight before the remote controller responds to the triggering operation of the key, and a user cannot visually distinguish the preset brightness, so that the backlight of the remote controller is ensured not to flicker when the remote controller transmits codes.
the infrared remote controller sends infrared signals based on 37.8KHz carrier waves when sending codes, the instantaneous current can reach more than 50mA when sending codes, the voltage fluctuation can reach more than 0.4V, in the embodiment, the remote controller drives the backlight lamp to continuously emit light with preset brightness during the low level period of the 37.8KHz carrier waves when sending codes, and stops driving the backlight lamp to emit light during the high level period of the 37.8KHz carrier waves, because the driving light-emitting frequency is high (the frequency that human eyes can feel the flicker is less than 50 Hz), human eyes can not feel the flicker of the backlight lamp, and the problem that the backlight lamp flickers when sending codes by the remote controller is effectively avoided.
The embodiment determines the target pulse voltage value of the backlight lamp when the triggering operation of the remote controller key is detected; and adjusting the driving voltage value of the backlight lamp according to the target pulse voltage value, and at the moment when the remote controller responds to the trigger operation code sending, because the backlight lamp is driven by the driving voltage value, the brightness of the backlight lamp continuously emits light at the preset brightness, thereby effectively avoiding the flickering of the backlight lamp when the remote controller sends the code.
In another embodiment, referring to fig. 5, based on the above embodiment, the step of determining the target pulse voltage value of the backlight lamp according to the first voltage value includes:
Step S141, determining a duty ratio of a driving voltage value of the backlight according to the first voltage value;
And step S142, determining a target pulse voltage value of the backlight lamp according to the duty ratio.
the driving voltage value of the backlight lamp is adjusted to achieve the target pulse voltage value, and the square wave duty ratio for driving the backlight lamp is adjusted under different battery voltages, so that the uniformity of the backlight lamp can be more favorably realized. For example, when the voltage values of the batteries are different, the duty ratios required for reaching the target pulse voltage value are different, a one-to-one correspondence relationship between each voltage value and the duty ratio of each battery is preset, and the one-to-one correspondence relationship between each voltage value and the duty ratio is stored in a preset storage area to generate a mapping relationship. When the electronic equipment is remotely controlled by using the remote controller, after a first voltage value of the battery is acquired, a duty ratio corresponding to the first voltage value is acquired according to a mapping relation between the voltage value and the duty ratio, and the proportion and the time of supplying the battery voltage to the backlight are adjusted based on the duty ratio of the driving voltage value of the backlight, so that the backlight continuously emits light at preset brightness.
For example, when the battery used for the remote controller is a common dry battery, the voltage range in which the backlight can be turned on is 2.2V to 3.5V, and the voltage range in which the backlight cannot be turned on is: and 0V-2.2V, the energy consumption can be saved by turning off the backlight lamp in a low voltage interval, the service time of the remote controller is prolonged, and meanwhile, the low-power icon flickers to remind a user of replacing the battery. When the battery voltage is in the range of 2.2V to 3.5V, a duty ratio level is set every 0.1V, for example, when 2.2V, the duty ratio of the driving voltage value is a%, when 2.3V, the duty ratio of the driving voltage value is B%, and when … 3.5.5V, the duty ratio of the driving voltage value is N%, and the specific corresponding relationship between the battery voltage value and the duty ratio can be seen as table one:
Table one:
| Voltage value V | Duty ratio% | voltage value V | duty ratio% |
| 2.2 | A | 2.9 | H |
| 2.3 | B | 3.0 | I |
| 2.4 | C | 3.1 | J |
| 2.5 | D | 3.2 | K |
| 2.6 | E | 3.3 | L |
| 2.7 | F | 3.4 | M |
| 2.8 | G | 3.5 | N |
the duty ratio corresponding to the voltage value is represented by A-N, the A-N are different values, the A-N gradually decrease with the increasing of the voltage value, and the A-N can sequentially decrease according to a fixed decreasing amount or irregularly decrease.
furthermore, the arrangement size of the duty ratio is related to the wear-out degree of the battery, and the larger the wear-out degree of the battery, the larger the duty ratio to be arranged, the smaller the damage degree of the battery, and the smaller the duty ratio to be arranged, wherein the wear-out degree of the battery reflects the freshness of the battery, the long service time of the battery, the large wear-out degree, and the small wear-out degree when the service time of the battery is shorter.
As shown in fig. 6, in order to more accurately control the brightness of the backlight and ensure that the backlight does not flicker, this embodiment also considers the influence of the wear-out degree of the battery on the target pulse voltage value, and when the wear-out degree of the battery is larger, a larger duty ratio needs to be configured to reach the target pulse voltage value, specifically, the step of determining the duty ratio of the driving voltage value of the backlight according to the first voltage value includes:
Step S1411, determining a degree of wear of the battery according to the first voltage value;
in step S1412, the duty ratio of the driving voltage value of the backlight is determined according to the degree of the consumption of the battery and the first voltage value.
In this embodiment, the corresponding relationship between each voltage value and the duty ratio is preset when the battery is worn to a large extent; meanwhile, the corresponding relation between each voltage value and the duty ratio is preset under the condition that the consumption degree of the battery is small, when the triggering operation of a remote controller key is detected, the consumption degree of the battery is judged firstly, and when the consumption degree of the battery is large, the duty ratio corresponding to the first voltage value is obtained from the corresponding relation between each voltage value and the duty ratio under the condition that the consumption degree is large; and when the degree of wear of the battery is small, acquiring the duty ratio corresponding to the first voltage value from the corresponding relation between each voltage value and the duty ratio under the condition of small degree of wear.
The duty ratio of the driving voltage value of the backlight is determined according to the degree of wear of the battery and the first voltage value, the duty ratio required when the backlight reaches the target pulse voltage value is different when the degree of wear of the battery is different, the duty ratio is adaptively adjusted according to the degree of wear, the target pulse voltage value can be more accurately acquired, the adjusting effect of the backlight is ensured, and the technical problem that the backlight flickers when the remote controller sends codes can be fundamentally solved.
it can be understood that the duty ratio can be calculated based on the functional relationship when the voltage value is detected by presetting the functional relationship between the voltage value and the duty ratio, and based on the functional relationship, the voltage value can be further refined instead of setting a duty ratio level every 0.1V, so as to realize more refined adjustment.
The function relation between the voltage value and the duty ratio is generated through historical adjustment data, for example, a preset initial function relation is generated, when the triggering operation of a remote controller key is detected, the detected first voltage value is recorded, the duty ratio is determined according to the preset initial function and the first voltage value, the light emitting brightness of the backlight lamp is adjusted according to the duty ratio, the controller adjusts the duty ratio according to the actual light emitting brightness, the adjusted duty ratio and the first voltage value are modified into the preset initial function relation to form a modified function, and when the remote controller is triggered to perform the key operation again, the duty ratio corresponding to the first voltage value is calculated according to the modified function. And calculating the duty ratio of the voltage value based on the corrected function, so that the adjusting effect of the backlight lamp is better.
It can be understood that, in this embodiment, the consumption degree of the battery is specifically determined by the voltage drop value of the battery when the remote control button is triggered to operate, and for example, the method for adjusting the backlight of the remote control further includes:
when the triggering operation of a remote controller key is detected, determining a voltage drop value of a battery;
when the voltage drop value of the battery is greater than or equal to a preset voltage difference, judging that the consumption degree of the battery is large;
and when the voltage drop value of the battery is smaller than the preset voltage difference, judging that the consumption degree of the battery is small.
when the degree of wear of the battery is different, the duty ratio of the driving voltage value of the backlight corresponding to the first voltage value is different, for example, when the degree of wear of the battery is large, the duty ratio of the driving voltage value of the backlight corresponding to the first voltage value is a first duty ratio, when the degree of wear of the battery is small, the duty ratio of the driving voltage value of the backlight corresponding to the first voltage value is a second duty ratio, and the first duty ratio is larger than the second duty ratio.
the wear-out degree is small for a new battery, when the key of the remote controller is triggered, the voltage of the battery is pulled down, the voltage drop of the new battery is small, when the key of the remote controller is triggered, the wear-out degree is large for an old battery, and when the voltage of the battery is pulled down, the voltage drop of the old battery is large. In this embodiment, the preset voltage difference is a critical value for determining a new battery and an old battery, and when the voltage drop value of the battery is greater than or equal to the preset voltage difference, it is determined that the voltage drop of the battery is large, which indicates that the battery is an old battery. And when the voltage drop value of the battery is smaller than the preset voltage difference, judging that the voltage drop of the battery is smaller, and indicating that the battery is a new battery.
in order to ensure the accuracy of the judgment of the consumption degree of the battery, the step of determining the voltage drop value of the battery comprises the following steps:
acquiring a plurality of voltage drop values, wherein the voltage drop values are detected when the remote controller keys are triggered at different occasions respectively;
Obtaining the average value of the voltage reduction values;
and taking the average value as the voltage drop value of the battery.
the loss degree of the battery is judged to be not accurate enough by adopting the voltage drop value detected once, and misjudgment is easy to occur. The voltage drop values are detected when the remote control keys are triggered at different occasions, for example, when the remote control keys are continuously triggered for multiple times, one voltage drop value is detected when the remote control keys are triggered once, when the remote control keys are triggered for multiple times, the voltage drop values are cumulatively acquired, and the average value of the voltage drop values is used as the voltage drop value of the battery to judge the loss degree of the battery.
When a user uses a remote controller to perform remote control operation, generally, the remote controller keys need to be triggered for many times, such as a television remote controller, operations such as channel switching or volume adjustment, display brightness adjustment, and the like, such as an air conditioner remote controller, after being triggered and started, operations such as temperature setting or wind speed adjustment, and the like need to be performed, generally, the triggering operation on the remote controller is continuous and multiple times of triggering operation, in this embodiment, a plurality of voltage drop values are obtained when connection is triggered at different times through the remote controller keys, and the problems that the obtaining time intervals of the voltage drop values are too long, and the accuracy of the loss degree of the battery is reduced are avoided. The voltage drop values can be different from 4 to 8.
In another embodiment, after the step of detecting the first voltage value of the battery of the remote controller, the method further includes:
judging whether the first voltage value is greater than or equal to a preset threshold value or not;
If yes, executing the step of determining the target pulse voltage value of the backlight lamp according to the first voltage value;
If not, the backlight lamp is turned off.
If the first voltage value of the battery is small, the requirement of the target pulse voltage value of the backlight lamp cannot be met when the battery voltage is distributed, the backlight lamp flickers when the remote controller sends a code, and the backlight lamp can be directly turned off to prevent the backlight lamp from flickering. And when the first voltage value is greater than or equal to 2.2V, determining the pulse voltage value of the backlight lamp according to the first voltage value, and further controlling the remote controller to adjust the driving voltage value of the backlight lamp according to the target pulse voltage value.
