Detailed Description
In order to make the technical solution of the present specification better understood by those skilled in the art, the technical solution of the present specification embodiment will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present specification, and it is apparent that the described embodiment is only a part of the embodiment of the present specification, but not all the embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.
Currently, users of smaller electronic devices, such as bluetooth headsets, are increasing. However, these small smart devices often are forgotten to be located in places where the user cannot find them, so that the user needs to take a long time to find them. In the prior art, the method for searching the small intelligent devices such as the earphone and the like can judge the distance between the intelligent mobile terminal and the small electronic device based on the intensity of the Bluetooth signal. However, this distance-based calculation method cannot indicate the direction in which the small electronic device is located, so that the user needs to walk around to know which direction the small intelligent device is located, and thus find the small electronic device. Another way is by sounding a bluetooth headset and then the user uses his ear to tell which direction the headset is in. However, since the volume of sound produced by the earphone is generally small, it is sometimes difficult for the user to distinguish which direction the earphone is in.
Therefore, the embodiment of the specification provides a method for searching intelligent equipment by utilizing angle information, which can improve convenience of searching intelligent equipment by a user by utilizing an intelligent mobile terminal to a certain extent so as to improve user experience.
Referring to fig. 1, an embodiment of the present disclosure provides a method for searching for an intelligent device, where the method is applied to an intelligent mobile terminal, and the method may include the following steps.
Step S110, a group of sound wave searching signals are sent by utilizing a built-in loudspeaker of the intelligent mobile terminal.
In this embodiment, the intelligent mobile terminal may be a portable intelligent device such as a mobile phone, a tablet computer, an intelligent watch, and an intelligent finger ring. The intelligent mobile terminal is internally provided with an inertial measurement unit (Inertial Measurement Unit, IMU) which can acquire motion gesture data of the intelligent mobile terminal. The intelligent device can be a small electronic device such as an intelligent earphone and an intelligent pen.
In this embodiment, the acoustic wave search signal is a set of acoustic wave signals sent by the intelligent mobile terminal, and the set of acoustic wave signals may include multiple frames of acoustic signals.
And step S120, acquiring the angle information of each sent frame of sound wave searching signal by utilizing an inertial measurement unit built in the intelligent mobile terminal.
In the embodiment, the IMU is a powerful tool capable of measuring and tracking the motion and the gesture of an object in real time, and is widely applied to various fields. By combining sensors such as accelerometers, gyroscopes and magnetometers, it can provide very accurate motion detection. IMUs are typically composed of several sensors, accelerometers, for measuring the linear acceleration of an object in various directions (e.g., acceleration along the X, Y, Z axis). Through the accelerometer, the IMU is able to sense the motion, tilt angle, and gravity changes of the object. Gyroscopes are used to measure the angular velocity of an object, i.e. the rotational velocity of an object about a particular axis. Through the gyroscope, the IMU is able to obtain rotation information (e.g., rotation about the X, Y, Z axes) of the object. Magnetometers for measuring the strength of a magnetic field around an object and may be used to determine the orientation of the object. The IMU calculates the motion state and direction of the object in real time by collecting data of the accelerometer, gyroscope and other sensors and combining with advanced algorithms (such as a Kalman filter, a complementary filter and the like). The accelerometer may measure linear acceleration of the object. From these acceleration data, the velocity and position of the object can be deduced. The gyroscope may provide a rotational speed of the object. By integrating these angular velocity data, the angular (attitude) change of the object can be estimated. The magnetometer can provide the orientation of the object relative to the earth's magnetic field by measuring the strength and direction of the geomagnetic field, thereby helping to correct errors in accelerometers and gyroscopes, and particularly avoiding drift during long term use.
In this embodiment, while the acoustic wave search signal is being transmitted, each frame of acoustic wave signal may correspond to one piece of angle information, and then the frame of acoustic wave signal and the angle information may be stored correspondingly and remain in use in a subsequent step.
And step 130, determining the energy intensity of the sound wave searching signal of each frame based on the recording data fed back by the intelligent equipment, wherein the recording data is fed back to the intelligent mobile terminal after the microphone of the intelligent equipment detects the sound wave searching signal.
In this embodiment, the smart device keeps the microphone in a listening state, after receiving the acoustic wave search signal, may record the acoustic wave search signal, and then feed back the recorded acoustic wave search signal to the smart mobile terminal through bluetooth or WiFi. After receiving the recording data, the intelligent mobile terminal analyzes the energy intensity of the sound wave searching signals and determines the energy intensity of the ultrasonic searching signals in each frame.
And step 140, determining the angle information corresponding to the acoustic wave searching signal with the maximum energy intensity as the azimuth of the intelligent equipment.
In this embodiment, the sound waves lose energy during propagation and are converted into heat energy. Thus, the closer the smart device is to the smart mobile terminal, the greater its energy intensity. When the user holds the sound wave searching signal sent by the intelligent mobile terminal in the swinging process, the angle of the sound wave searching signal is continuously changed, and when the energy recorded by the intelligent device is strongest, the distance between the intelligent mobile terminal and the intelligent device is the smallest, and the direction indicated by the loudspeaker of the mobile terminal is the azimuth of the intelligent device. Therefore, the user can search for the intelligent device in the azimuth, does not need to walk around and then judge where the device is based on the energy of the Bluetooth signal, and the efficiency and convenience of searching for the intelligent device by the user are improved to a certain extent.
In some embodiments, the method may further include determining an azimuth of the smart device as an initial angle, adjusting a position of the smart mobile terminal based on the initial angle, performing a loop process until the initial angle is within a preset deviation range of a target angle, wherein the preset deviation range of the target angle points to a position where the smart device is found, controlling the smart mobile terminal to swing within the initial angle range, sending a set of sound wave search signals by using a speaker built in the smart mobile terminal, acquiring angle information of each sent sound wave search signal by using an inertial measurement unit built in the smart mobile terminal, determining energy intensity of each sound wave search signal based on recording data fed back by the smart device, and determining angle information corresponding to the sound wave search signal with the maximum energy intensity as the initial angle of the smart device.
In this embodiment, since the indication may indicate the approximate azimuth of the intelligent device once, the user may further swing the intelligent mobile terminal continuously in the process of moving to the intelligent device, and further determine the azimuth of the intelligent device by using the method described in the above embodiment until the user finds the intelligent device.
In a specific embodiment, the intelligent mobile terminal is a mobile phone, and the intelligent device is a headset. The user wants to find the position of the headset using the handset. Firstly, a user swings the mobile phone and sends an acoustic wave searching signal in the process of the user swinging the mobile phone, and at the moment, the IMU can acquire an angle signal of each frame of acoustic wave searching signal. After receiving the sound wave searching signal, the earphone records the sound wave searching signal and transmits the sound wave searching signal back to the intelligent device through Bluetooth. The mobile phone can determine that the angle when the signal strength is maximum is the initial angle alpha 0 based on the recording data returned by the earphone. Then, based on the initial angle α 0, an earphone is found, and angle correction β 0 is performed with respect to the initial angle α 0, so as to obtain a first corrected angle (α 0-β0), then (α 0-β0) is taken as the initial angle, and the correction angle β 1 is obtained after the correction operation, where the corrected initial angle is (α 0-β0-β1), and thus, the corrected angle β n-1 after n times of correction is performed, so that the target angle (α 0-β0-β1-…-βn-1) can be obtained, and the earphone is found.
In some embodiments, the acoustic wave search signal is an ultrasonic signal.
In the present embodiment, the ultrasonic signal is an acoustic signal having a frequency higher than the human auditory range (usually 20kHz or more). The ultrasonic energy is concentrated, so that stronger directional propagation can be realized. Typically, the ultrasound signals will form a relatively narrow beam that facilitates detection of a particular region or object. The ultrasonic wave is affected by the medium change in the propagation process, and reflection, refraction and scattering phenomena occur. According to the intensity and time delay of the reflected signals, the information such as the distance, the shape and the internal structure of the object can be judged. The propagation of ultrasonic waves is attenuated by absorption, scattering, propagation distance, and the like of the medium. In particular in air, the attenuation of ultrasonic waves is significant. Therefore, the position of the intelligent device can be determined more accurately by using the ultrasonic signals. And the ultrasonic wave belongs to inaudible sound, and when an ultrasonic wave signal is used as an acoustic wave searching signal, interference to human ears can not be generated.
