Description of the embodiments
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, based on the examples herein, which are within the scope of the protection sought by those of ordinary skill in the art without undue effort, are intended to be encompassed by the present application.
As described in the background art, in the current remote controller, it is difficult for a user to know the current electric quantity condition of the battery in real time, so that a sudden power failure condition may occur in the use process, and if the user does not prepare the standby battery in advance, or is difficult to find or take the standby battery at a time, the control can only be realized by operating the device in a short distance, so that the user experience is very affected. Especially, the wall-hanging type air conditioner and other devices are very poor in experience because of the fact that the close-range operation is very inconvenient due to the fact that the setting position is high.
In order to solve the problem, the remote controller is improved based on the existing remote controller, so that a user is prompted in time in the using process of the remote controller, and the situation that a battery suddenly loses electricity is avoided.
Specifically, a display screen and a backlight source are arranged in many existing remote controllers, and the working state and working parameters of controlled equipment can be displayed through the display screen, so that the user can conveniently check the working state and the working parameters; through the backlight, under the condition of bad light conditions such as night, can help the user to see screen and button clearly better, convenience of customers uses.
The light emission luminance of the backlight is positively correlated with the voltage across the backlight, that is, the larger the voltage is, the larger the light emission luminance is. The voltage at two ends of the backlight source is positively correlated with the output voltage of the battery, and the output voltage of the battery is positively correlated with the electric quantity of the battery. Therefore, in practice, the light emission brightness of the backlight is positively correlated with the battery power. Based on this principle, the battery capacity and voltage can be reflected to some extent by the light emission luminance of the backlight.
The remote controller is based on the principle, and the related information of the battery electric quantity of the remote controller is prompted by detecting the brightness information when the backlight source emits light, so that the situation that the battery is suddenly dead is avoided, and the use experience of a user is improved. The specific implementations are described below without limitation by way of several examples or embodiments.
Referring to fig. 1, fig. 1 is a flowchart of a method for prompting battery power of a remote controller according to an embodiment of the present application, as shown in fig. 1, in this embodiment, the method for prompting battery power of a remote controller includes:
step S11: when any key of the remote controller is detected to be triggered, the backlight source is controlled to emit light.
Specifically, in order to reduce power consumption, when the remote controller is not in use, the backlight source is in a dormant state, and light emission is stopped. When any key of the remote controller is triggered, the user is indicated to use the remote controller, so that the backlight source is controlled to emit light so as to illuminate the display screen and/or the key, and the user can conveniently check and use the remote controller.
In practice, when the battery of the remote controller is turned on, all keys of the remote controller are periodically scanned in a matrix to determine whether a certain key is pressed. If a certain key is detected to be pressed, the key is triggered. When a certain time passes and all keys are not triggered, the backlight source can be controlled to stop emitting light, and the sleep state is restored.
Step S12: and detecting brightness information of a plurality of preset monitoring points of the remote controller, and determining information to be displayed based on the brightness information of the plurality of preset monitoring points. The information to be displayed is related to the battery power of the remote controller.
Specifically, when the backlight emits light, a certain area of the remote controller is illuminated, but the brightness of different positions may be different. Therefore, in order to detect the brightness information more accurately, a plurality of monitoring points can be preset according to the internal structure of the remote controller, and then when the brightness information is detected, the brightness information of the preset monitoring points is detected, so that the detection error of a single monitoring point is avoided.
More specifically, a plurality of preset monitoring points may be disposed at positions at different distances from the backlight, for example, the plurality of preset monitoring points may be disposed on one side of the position of the backlight. As shown in fig. 2, five monitoring points (1) - (5) are sequentially arranged on one side of the position of the backlight AK, and the five monitoring points are distributed at the positions close to four corners and the center of the remote controller, so that a larger range of the remote controller is covered as much as possible.
Based on this, in some embodiments, step S12 may specifically be when detecting the brightness information of a plurality of preset monitoring points of the remote controller: and sequentially detecting the brightness information of each preset monitoring point according to the sequence gradually far away from the backlight source.
Specifically, in practice, the luminance information of each monitoring point may be detected by a scanner. Therefore, when the brightness information of each preset monitoring point is detected in sequence according to the sequence gradually far away from the backlight source, the scanner is convenient to quickly complete scanning detection, and the brightness information can be captured in real time.
It is understood that the number of preset monitoring points is not limited to 5, and the setting positions are not limited, so long as the corresponding purpose can be achieved.
And after the brightness information of each preset monitoring point is obtained, further processing is carried out, and the information to be displayed is determined. The information to be displayed is prompt information to be displayed at a specific position of the display screen. Through the prompt information, the user can know the information related to the battery power of the remote controller in time.
In some embodiments, in step S12, the specific implementation process of determining the information to be displayed based on the brightness information of the plurality of preset monitoring points may include:
calculating a brightness average value based on brightness information of a plurality of preset monitoring points; and determining information to be displayed based on the brightness average value.
By calculating the brightness average value of a plurality of preset monitoring points, the detection error of a single position can be avoided, and the detection precision is ensured. And further the information to be displayed can be determined based on the luminance average value.
Of course, it is understood that, since the purpose of the present application is not merely to detect the brightness information of the backlight source, but to prompt the user based on the brightness information, in other embodiments, the information to be displayed may be determined without calculating the brightness average value, for example, the information to be displayed may be determined directly based on the brightness sum of each preset monitoring point.
It should be noted that, the brightness information of each preset monitoring point collected and output by the scanner is an analog signal, so if the selected processing module can only process digital signals, the brightness information output by the scanner is subjected to analog-to-digital conversion by the a/D converter, and then is sent to the processing module for subsequent processing, including calculating an average value and the like.
Further, in some embodiments, the information to be displayed may include one or more of a luminance value, a character, or a graphic.
Wherein the brightness value, that is, the real brightness data (such as average brightness of a plurality of preset monitoring points) obtained by processing is in the form of Acd/m 2 Such as 100cd/m 2 . Since the lower the battery level (lower the voltage), the lower the light emission luminance of the backlight, different battery levels (battery voltages) can be represented by different luminance values. When the information to be displayed is a luminance value, the battery power status information represented by different luminance values can be described by a device specification or the like, for example, when the luminance information is greater than A1 cd/m 2 When the battery is in full charge; when the brightness information is in A2-A1 cd/m 2 When the battery is in a proper state, the battery electric quantity is indicated; when the brightness information is in A3-A2 cd/m 2 When the battery power is lower; when the brightness information is smaller than A3 cd/m 2 When the battery power is low, the battery needs to be replaced as soon as possible, and the influence on use is avoided. The specific brightness value range can be set according to actual conditions. In particular, it may be determined based on the actual circuit design (including the rated parameters of the battery used, the rated parameters of the backlight, and the rated parameters of other loads, etc.).
The characters may include numbers, kanji or foreign letters, etc. Different characters may be set to represent different power states, such as high, medium, low, etc. kanji characters to represent the level of battery power.
The graph can be, for example, an icon similar to that in a mobile phone for displaying electric quantity, and different electric quantity states are represented by different numbers of grids.
Step S13: and displaying the information to be displayed in the display screen.
The information to be displayed, which is determined in the previous step, is displayed in the display screen, so that a good prompt effect can be achieved for a user, and after the user sees the displayed prompt information, the state of charge of the battery of the remote controller can be known in time. If the battery is sufficient in electric quantity, the battery can be used with confidence; if the battery power is reduced to a certain value, a standby battery can be prepared in time; if the battery power is low, the battery can be replaced as soon as possible, and sudden no electric effect is avoided.
Based on the above description, the technical solution provided by the embodiments of the present application may include the following beneficial effects:
according to the battery power prompting method, the device, the controller and the remote controller provided by the embodiment of the invention, the remote controller comprises a display screen and a backlight source, when any key of the remote controller is detected to be triggered, the backlight source is controlled to emit light, the brightness information of a plurality of preset monitoring points of the remote controller is detected, the information to be displayed is determined based on the brightness information of the plurality of preset monitoring points, and the information to be displayed is displayed in the display screen. So set up, because the luminance of backlight exists the relevance with battery voltage, therefore luminance information when shining through the backlight can characterize battery voltage and electric quantity related information, then treat the display information and show based on luminance information generation again, can indicate the user to make the user in-process that uses the remote controller, can in time know battery electric quantity related information, if the electric quantity is lower, then can in time change the battery, avoid appearing controlling the problem of inefficacy, effectively improve user's use experience.
In addition, in some embodiments, after determining the average brightness value of the plurality of preset monitoring points in step S12, the method may further include: determining a brightness interval in which the brightness average value is positioned; and determining the gray value of the information to be displayed based on the brightness interval where the brightness average value is located. Correspondingly, in the foregoing steps, displaying the information to be displayed in the display screen includes: and displaying the information to be displayed in the display screen according to the corresponding gray value.
Specifically, in this embodiment, a plurality of brightness intervals may be divided in advance, and different brightness intervals may correspond to different electric quantity state information, for example, when the brightness information is greater than A1 cd/m 2 When the battery is in full charge; when the brightness information is in A2-A1 cd/m 2 When the battery is in a proper state, the battery electric quantity is indicated; when the brightness information is in A3-A2 cd/m 2 When the battery power is lower; when the brightness information is smaller than A3 cd/m 2 When the battery charge is low.
Based on this, after the luminance average value is calculated, the luminance section in which the luminance average value is located is further determined. And then determining the gray value of the information to be displayed based on the brightness interval where the brightness average value is located. The gray value is the pixel luminance value when an image is displayed on the display screen, and the larger the gray value is, the larger the pixel luminance is. In a conventional remote controller, a black-and-white liquid crystal display is generally used, and contents (such as characters) are displayed in black parts, so that the smaller the gray value is, the clearer the display is.
According to the principle, when the brightness intervals in which the average brightness value is located are different, the information to be displayed can be displayed in different gray values in the display screen, so that the user is prompted in another form. For example, the lower the battery power, the clearer and more obvious the prompt information is displayed, thereby being more convenient for the user to check.
Furthermore, in some embodiments, the method may further include: after controlling the backlight to emit light, determining the voltage at two ends of the backlight and/or the current flowing through the backlight; if the voltage at two ends of the backlight source is smaller than a preset voltage threshold value and/or the current flowing through the backlight source is smaller than a preset current threshold value, generating low-power prompting information and prompting through a display screen.
Specifically, as the battery power decreases, the voltage and current output by the battery also decreases, and thus the light emission brightness of the backlight source also decreases. Therefore, in this embodiment, the voltage at two ends of the backlight source and/or the current flowing through the backlight source can be directly obtained, and then the obtained voltage and/or current can be used as a condition for judging whether the battery power is low. The voltage threshold and the current threshold can be predetermined according to the circuit structure, and when the voltage of the backlight source is lower than the voltage threshold or the current of the backlight source is lower than the current threshold, the low battery level is indicated, so that low battery level prompt information can be generated, and the user is prompted through the display screen to prompt the user to replace the battery in time.
Further, in some embodiments, determining the voltage across the backlight and/or the current through the backlight includes:
detecting the voltage at two ends of the backlight source through a voltage detection module, and detecting the current flowing through the backlight source through a current detection module; or detecting the voltage at two ends of the battery of the remote controller through a voltage detection module and detecting the current flowing through the battery of the remote controller through a current detection module; the voltage across the backlight is calculated based on the voltage across the battery of the remote control, and the current across the backlight is calculated based on the current across the remote control.
The voltage and the current of the backlight source can be determined in two ways, namely, the voltage detection module and the current detection module are directly utilized for detection, the voltage detection module and the current detection module are utilized for detecting the real-time voltage and the current of the battery, and the voltage and the current of the backlight source are calculated based on rated parameters of other loads in the remote controller. The two modes can achieve the purpose, but the adopted circuit structure is different, and the selection can be carried out according to the needs in practice.
For better understanding, the following description is given by way of an example. Referring to fig. 3, fig. 3 is a flow chart of a method for prompting battery power of a remote controller according to another embodiment of the present application, and as shown in fig. 3, the method for prompting battery power of the remote controller includes the following steps:
firstly, judging whether the remote controller is powered.
If the battery supplies power normally, all keys of the remote controller are scanned in a matrix mode, and if the keys of the remote controller are not detected to be pressed down, the backlight source is not started to work; when any key of the remote controller is detected to be pressed, the backlight source and the monitor are started to work.
The monitor starts a current and voltage monitoring tracking mode, the voltage monitoring comprises monitoring of the power supply voltage of a remote controller and monitoring of the voltage Vak at two ends of the backlight source, the current monitoring monitors the real-time current state of the backlight source, and the monitoring result is fed back to the control module; the control module controls the backlight source to work through the current and the voltage fed back by the monitor, and according to the preset voltage threshold value and the preset current threshold value of the backlight source, if the voltage or the current at two ends of the backlight source is lower than the corresponding threshold value, the control module feeds back the value to the A/D converter under the combined action of the monitor and the controller module, the A/D converter feeds back the relevant information of the remote controller, such as insufficient electric quantity, of the remote controller to be reminded, and the process plays a role in reminding the relevant information of the voltage, the insufficient electric quantity of the current and the like, and essentially reminding the battery of the insufficient electric quantity.
When the backlight source receives the trigger signal and the voltage, the backlight source is synchronously started to work, namely the backlight source is lightened, at the moment, the brightness detector can detect brightness information of a plurality of preset monitoring points, the detection sequence is that scanning detection is started from two ends of the backlight source AK, the sequence of the monitoring points is (1), (2), (3), (4) and (5) shown in fig. 2, when each monitoring point is detected, numerical values are fed back to the A/D converter, brightness average values are obtained according to the five monitoring points, and the brightness average values are fed back to an I/O port of a liquid crystal screen of the remote controller through the A/D converter after calibration.
When the remote controller receives the average brightness value fed back by the converter and the sampler, the internal program displays the value on the liquid crystal display screen of the remote controller through the converter according to the feedback values of the backlight source and the liquid crystal I/O, specifically, the value of the brightness value of the backlight source (the average value obtained by the calculation) and an icon (the format is that the value is plus the icon, the brightness value is 100 in an example, the icon is cd/-square meter, and the value is 100 cd/-square meter, wherein the size 100 can be changed along with the voltage value) are displayed on the liquid crystal display screen of the remote controller. The brightness can be displayed in a segmented mode according to the voltage, when a new battery is used, the brightness value of the backlight source is the maximum value, and the brightness is reduced along with the weakening of the voltage, so that the relevance and the accuracy are realized, the brightness degree of the backlight source can be seen by a user in time, and the experience of the user is improved.
