As shown in fig. 3, where 1 is the duty cycle 100%, the buzzer sounds all the time, and 2 is the duty cycle 50%, the buzzer sounds for one second and then stops for one second.
It can be understood that after the user sets the sounding type of the buzzer on the television, the television generates a sounding type instruction and sends the sounding type instruction to the remote controller, and the remote controller sets the sounding type of the buzzer according to the sounding type instruction.
Further, step S20 further includes: the television collects the preset sound and determines a first azimuth of the remote controller according to the preset sound; when the remote controller receives a playing instruction, scanning AP signals of the television and a preset wireless access point to obtain signal intensity information, and sending the signal intensity information to the television; the television determines a second azimuth of the remote controller according to the signal intensity information, determines a target azimuth of the remote controller according to the first azimuth and the second azimuth, and displays a predicted position of the remote controller according to the target azimuth.
It should be noted that, after the remote controller emits the preset sound, the television may identify the preset sound emitted by the remote controller, and determine the sound source position, i.e. the first direction of the remote controller, according to the preset sound.
Further, the television set includes: a microphone array, a distance determination module, and a position determination module; the microphone array collects preset sound to obtain sound intensity; the distance determining module determines the distance between the remote controller and each microphone in the microphone array according to the sound intensity; the position determining module determines a first position of the remote controller according to the distance and the position of each microphone in the microphone array.
It can be understood that the microphone array can be arranged on the upper frame or the lower frame of the television, the distance between the microphones in the microphone array can be 10-20 cm, and the microphones collect preset sounds, so that the sound intensity of the preset sounds collected by the microphones is obtained.
It should be noted that, the initial sound intensity of the preset sound emitted by the remote controller at the position where the remote controller is located is fixed, so that a difference value (i.e. a sound attenuation amount) between the initial sound intensity and the sound intensity collected by each microphone can be calculated, and according to the relationship between the sound attenuation amount and the distance, the distance between the remote controller and each microphone is obtained, and the relationship formula is as follows:
b=20 lg D formula one;
wherein B is the sound attenuation amount, and D is the distance.
It will be appreciated that since the position of each microphone in the microphone array is known, the sound source position, i.e. the first position of the remote control, can be determined from the intersection of the distances.
It should be noted that, the remote controller is further provided with a wireless network card, when the remote controller receives the playing instruction and sends out the preset sound, the built-in wireless network card also starts to work, the wireless network card scans and obtains the AP signal sent by the television and the AP signal sent by the preset wireless access point, and the preset wireless access point can be a wireless router existing in the home.
It can be understood that the wireless network card obtains signal strength information by scanning an AP signal, where the signal strength information includes a correspondence between signal strength and MAC address, and the signal strength information includes signal strength of a video camera and a preset wireless access point.
Further, the television set includes: the signal strength determining module and the position display module; the signal strength determining module determines first signal strength of the remote controller and a preset wireless access point and second signal strength of the remote controller and the television according to the signal strength information; the distance determining module determines a first distance according to the first signal intensity and determines a second distance according to the second signal intensity; the azimuth determining module determines a second azimuth of the remote controller according to the position of the preset wireless access point, the position of the television, the first distance and the second distance; and the position display module corrects the first azimuth according to the second azimuth to obtain a target azimuth, and displays the predicted position of the remote controller according to the target azimuth.
In a specific implementation, after the television is connected with the preset wireless access point through WiFi, parameters of the preset wireless access point are obtained, wherein the parameters comprise the position of the preset wireless access point, the initial signal strength of the sent AP signal, the working frequency of the sent signal, the MAC address and the like. After receiving the signal intensity information, the television can identify the television and the signal intensity of the preset wireless access point according to the MAC address, the television calculates the signal intensity difference between the preset wireless access point and the remote controller, namely, the first signal intensity, and the signal intensity difference between the television and the remote controller, namely, the second signal intensity, and determines the first distance between the preset wireless access point and the remote controller and the second distance between the television and the remote controller according to the relation between the signal intensity difference and the distance, wherein the relation formula of the signal intensity difference and the distance is as follows:
lfs= 32.44+20lg D+20lg f formula two;
wherein Lfs is the signal intensity difference, D is the distance, and f is the signal operating frequency.
It should be noted that, according to the positions of the television and the preset wireless access point, and the first distance and the second distance, the distance intersection point, that is, the second direction of the remote controller is determined.
In a specific implementation, according to the difference between the first azimuth and the second azimuth, an average value of the difference is obtained, and the distance of the average value is moved in the direction of the first azimuth to the second azimuth, so that a target azimuth is obtained, and at the moment, the position relation between the target azimuth and the television is displayed on the UI of the television, namely, the predicted azimuth of the remote controller is displayed.
In this embodiment, the television establishes communication connection with the remote controller, and when receiving a remote controller searching instruction, sends a playing instruction to the remote controller; and when receiving the playing instruction, the remote controller sends out a preset sound to remind a user to search. Through the mode, when the user cannot find the remote controller, the television sends the playing instruction to the remote controller through the communication connection established with the remote controller, so that the remote controller emits sound, and the user can search for the remote control more quickly according to the sound at the moment, and the user experience is greatly improved.
