Along with the development of intellectualization and miniaturization of the terminal, the application of the terminal equipment is increasingly integrated into life and entertainment of the user, and great convenience is brought to the user. Because the size of the terminal is smaller and smaller, the terminal is lost to a clothes pocket, a back cushion gap or other inconspicuous corners, and difficulty is brought to a user in searching the terminal. In the related art, a mode of controlling the terminal to vibrate or make a sound is used for assisting a user to find the terminal, but the user cannot provide effective help for the user because the user can not directly locate the position of the terminal.
In addition, in the related art, the lost terminal is controlled to emit sound with larger volume so as to assist the user to find the lost terminal, but under a noisy environment or under the condition that the user does not want to make the terminal emit sound with larger volume to disturb other people, the user is not provided with effective help in a mode of reminding the user through the sound.
Therefore, in view of one or more of the above-mentioned problems, the embodiments of the present application provide a terminal positioning method, apparatus, electronic device, and readable storage medium, which can position a terminal whose position is unknown, provide accurate positioning prompt information of the terminal to a user, and bring convenience to the user to find the terminal.
The terminal positioning method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
The terminal positioning method provided by the embodiment of the application can be applied to a first terminal, wherein the first terminal comprises two microphones with different positions, and the first terminal is in communication connection with a second terminal.
In an exemplary case where the second terminal is lost or the like and is at a position unknown to the user, the first terminal can be in communication connection with the second terminal to control the second terminal, so that the first terminal can locate the position of the second terminal and generate location prompt information to assist the user in finding the second terminal.
Optionally, the communication connection may be a wireless communication manner such as bluetooth, a wireless local area network, a mobile communication network, and radio frequency identification.
The first terminal comprises two microphones of different locations, it being understood that the total number of microphones comprised in the first terminal may be two or more. For example, the first terminal may be a device with a communication function, such as a mobile phone, a tablet computer, a notebook computer, a palm computer, or an Ultra-Mobile Personal Computer (UMPC) mobile personal computer. The second terminal may be a bluetooth headset, a watch, a bracelet, a mobile phone or the like capable of communicating with the first terminal.
Fig. 1 is a flowchart of a terminal positioning method according to an embodiment of the present application, and in conjunction with the method shown in fig. 1, specifically, in conjunction with the method shown in fig. 1, the method may include steps 110 to 140.
Step 110, sending a control signal to the second terminal so that the second terminal responds to the control signal to send out an audio signal;
step 120, in response to each microphone receiving the audio signal, determining distance information of the microphone from the second terminal, the distance information including a distance of each microphone from the second terminal;
step 130, determining relative position information of the first terminal and the second terminal according to the distance between the two microphones and the second terminal and the distance between the two microphones;
and 140, displaying positioning prompt information according to the relative position information, wherein the positioning prompt information comprises at least one of a guiding direction and a distance between the first terminal and the second terminal.
The above steps are described in detail below, and are specifically described below.
First, referring to the above steps 110 and 120, the first terminal may transmit a control signal to the second terminal, the control signal being used to instruct the second terminal to play the audio signal.
Specifically, the second terminal may include preset audio output parameter information, and in case that the audio play parameter information is not set by the user, the second terminal may select to output the audio signal using the preset audio output parameter information.
The preset audio output parameter information of the second terminal may be determined by combining factors that affect the standby duration of the second terminal, such as audio output power, battery capacity, etc., for example, the battery capacity is smaller, and the power consumption consumed by the second terminal for outputting the audio signal may be made smaller by adopting smaller audio amplitude, audio frequency, etc., where the preset audio output parameter information is not specifically limited.
As a specific example, the preset audio output parameter information may include an audio frequency, optionally, the audio frequency may be set in combination with a frequency band corresponding to the aural capability of the human ear, for example, if the user often uses the second terminal in a quiet space, the audio frequency may be set to be smaller than the frequency band corresponding to the aural capability of the human ear, and since the range of the frequency band receivable by the microphone is larger than the frequency band corresponding to the aural capability of the human ear, the audio frequency is set to be smaller than the frequency band corresponding to the aural capability of the human ear, the microphone may also detect the audio signal, and may not disturb other users in the environment where the user is located. Alternatively, the audio frequency may be set to be larger than the frequency band corresponding to the auditory ability of the human ear, and the microphone may detect the audio signal as well without being heard by the human ear. Based on this, the second terminal can reduce interference with other users when outputting the audio signal.
In addition, the user can set the audio frequency to a frequency band corresponding to the auditory ability of human ears, so that the microphone can receive the audio signals, and meanwhile, the user can hear the audio signals through human ears, so that the user can find the general direction of the second terminal through sound on one hand, and can search the second terminal by using prompt information generated by the first terminal based on the detected audio signals.
In yet another example, the preset audio output parameter information may include audio output power, for example, the audio output power may be set in combination with a battery capacity of the second terminal itself, for example, in a case where the battery capacity is small, the audio signal is preferentially output using the lower audio output power, so that a standby period of the second terminal may be provided, and a power consumption of the second terminal may be avoided.
The second terminal indicates the sounding signal based on the control signal, and after the microphone of the first terminal acquires the environmental sound for acquisition, the audio signal and noise except the audio signal in the environment can be accurately identified.
After each microphone in the first terminal receives the audio signal, distance information between the microphone and the second terminal can be determined, so that the distance between each microphone and the second terminal is obtained.
Next, referring to step 130 above, the positions of the two microphones in the first terminal are known, and thus the spacing between the two microphones is also known. After the distances between the two microphones and the second terminal are obtained, the relative position information of the first terminal and the second terminal can be determined in a triangular positioning mode, and the relative position information can include included angle information and distance information, for example, an included angle formed by a connecting line formed by each microphone and the second terminal and a connecting line formed by the two microphones. Fig. 2 is a schematic diagram of a terminal position provided in the embodiment of the present application, and referring to fig. 2, the first terminal 10 includes a first microphone 11 and a second microphone 12, the first microphone 11 and the second microphone 12 form a connection 100, the first microphone 11 and the second terminal form a connection 101, the second microphone 12 and the second terminal form a connection 102, and by means of triangle positioning, angles corresponding to the included angle α and the included angle θ can be determined.
After determining the relative position information, referring to step 140, the positioning prompt information may be determined according to the relative position information, and the positioning prompt information is displayed through the first terminal, so that the user may find the second terminal conveniently.
The positioning prompt information may include a guiding direction, a distance between the first terminal and the second terminal, and both the guiding direction and the distance. For example, the guiding direction may point to the position of the second terminal, so that the user may be assisted to find the second terminal, and for example, the first terminal may display a distance from the second terminal, and as the terminal moves, the distance between the first terminal and the second terminal changes correspondingly, and in the case that the distance becomes smaller, the closer the positions of the first terminal and the second terminal are indicated.
The guiding direction may be a direction in which the first terminal points to the second terminal, and in some embodiments, alternatively, the preset position may be selected from the first terminal to represent the position of the first terminal, for example, the first microphone may be used as the preset position, the position of the first microphone may be used to represent the position of the first terminal, and in addition, the position of the second microphone may be used to represent the position of the first terminal. After the preset position is determined, the guiding direction can be conveniently determined.
According to the embodiment of the application, the first terminal sends the audio signal by combining the second terminal, and the distance between the two microphones and the second terminal is determined, so that the relative position information of the first terminal and the second terminal can be rapidly and accurately determined, and at least one of the guiding direction and the distance between the first terminal and the second terminal can be determined according to the relative position information. By displaying at least one of the guiding direction and the distance between the first terminal and the second terminal, accurate positioning prompt information is provided for the user, and convenience is brought to the user for searching the target terminal.
In some optional embodiments, the user may adjust an audio output mode of the audio signal, specifically, the audio signal corresponds to at least one audio output mode, the audio output mode corresponds to audio output parameter information one by one, and audio output power or audio output frequency between different audio output parameter information is different;
the step 110 of sending a control signal to the second terminal may specifically include steps 1101 to 1103.
Step 1101, receiving an input selecting a target audio output mode from the at least one audio output mode;
Step 1102, in response to an input for selecting a target audio output mode, determining audio output parameter information corresponding to the target audio output mode as first target audio output parameter information;
and step 1103, a control signal is sent to the second terminal, where the control signal is used to instruct the second terminal to output an audio signal according to the first target audio output parameter information.
In an exemplary process, the user may adjust the audio output parameter information of the audio signal through the first terminal in a process of searching for the second terminal, so as to adjust the audio signal output by the second terminal.
Optionally, in embodiments of the present application, one or more audio output modes are provided for a user to select, where multiple means two or more. For example, the display interface of the first terminal may include a plurality of audio output modes, such as a low power consumption mute mode, a high power consumption mute mode, a low power consumption voiced mode, a high power consumption voiced mode, and the like.
The different power consumption modes can control the transmission distance of the audio signal, for example, when the user gets up in the morning, if the user does not want to disturb the sleep of other people because the earphone emits a larger sound, the low-power consumption mute mode can be adopted, at this time, the second terminal outputs the audio signal in the form of ultrasonic wave, the microphone can effectively receive the audio signal in the frequency band range corresponding to the ultrasonic wave, and most of users cannot hear the audio signal. Optionally, the range that the user needs to look for is bigger, can adopt the silence mode of high-power consumption, and in this way, the second terminal can improve the increase power voltage to for the form of ultrasonic wave, output audio frequency range is higher audio frequency signal, and in this way, audio frequency signal can transmit the farther distance, is favorable to the microphone of first terminal to receive audio frequency signal.
It is understood that the second terminal may sense through hearing the audio signal output based on the low power consumption voiced mode or the high power consumption voiced mode. The sound transmission distance corresponding to the high-power-consumption sound mode is larger than the sound transmission distance corresponding to the low-power-consumption sound mode.
Optionally, the first terminal may also provide a more detailed parameter adjustment control after the user selects one of the audio output modes. The parameter adjustment controls may include frequency adjustment controls, power adjustment controls, and the like. Specifically, in the low power consumption mute mode or the high power consumption mute mode, for example, based on the frequency adjustment control, the user can select the audio frequency in the frequency band range of 6KHz to 10KHz, and in the mute mode, the user can select the audio frequency in the frequency band range of 0 to 100 Hz.
In the low-power-consumption mute mode, for example, based on the power adjustment control, the transmission distance of the audio signal can be adjusted by adjusting the power, wherein the larger the power is, the farther the transmission distance of the audio signal is.
According to the embodiment of the application, the user can adjust the audio output mode at the first terminal, so that the convenience for the user to find the second terminal can be improved. For example, the transmission distance of the audio signal can be increased by adjusting the audio output power, so that the user can find the second terminal conveniently under the condition that the second terminal is far away from the first terminal; for another example, the user may adjust the audio output frequency to be within the range of the human ear hearing, thereby facilitating the user to find the second terminal through hearing.
In some embodiments, the first terminal recognizes the audio signal transmitted from the second terminal by collecting the environmental audio, and determines the distance information from the second terminal according to receiving the audio signal transmitted from the second terminal. Specifically, the audio signal corresponds to the second target audio output parameter information, and in response to each microphone receiving the audio signal, the distance information between the microphone and the second terminal is determined, and steps 1201 to 1203 may be described below.
Step 1201, acquiring environmental audio acquired by each microphone;
step 1202, detecting whether the environmental audio collected by each microphone includes an audio signal corresponding to the second target audio output parameter information;
step 1203, corresponding to each microphone, determining distance information between the microphone and the second terminal when the environmental audio includes the audio signal corresponding to the second target audio output parameter information.
Specifically, the second target audio output parameter information may be preset audio output parameter information, or may be audio output parameter information corresponding to a target audio output mode selected by the user, that is, the first target audio output parameter information.
The first terminal acquires the environmental audio collected by each microphone and detects the environmental audio, so that whether an audio signal sent by the second terminal is received or not can be determined. For example, the first terminal may acquire an audio feature of the audio signal, and determine whether the audio signal transmitted by the second terminal is received by detecting whether the environmental audio includes a signal of the audio feature.
As a specific example, the audio features may include waveforms of the audio signal. For example, detecting whether the environmental audio collected by each microphone includes an audio signal corresponding to the second target audio output parameter information may refer to the following steps: corresponding to each microphone, filtering the environmental audio according to a filtering algorithm corresponding to the second target audio output parameter information to obtain filtered environmental audio; determining whether the environmental audio collected by the microphone comprises an audio signal corresponding to second target audio output parameter information according to whether the audio waveform corresponding to the filtered environmental audio is matched with the waveform corresponding to the audio signal; and under the condition that the filtered audio waveform is matched with the waveform corresponding to the audio signal, the environment audio comprises the audio signal corresponding to the second target audio output parameter information.
The waveform corresponding to the output audio signal of the second terminal may be a preset waveform, and the preset waveform may be a sine waveform, a square waveform, a pulse waveform, or the like, which is not specifically shown here. Different audio output parameter information may correspond to information of parameters such as different waveform phases, periods, waveform amplitudes, and the like, respectively.
After the first terminal sends the control signal through the second terminal, the second terminal responds to the control signal and sends out an audio signal corresponding to the second target audio output parameter information.
The audio signal sent by the second terminal is a signal with a rule and a corresponding frequency band, and the noise does not have the characteristic, so that the environmental audio collected by the microphone is filtered by selecting a filtering algorithm corresponding to the second target audio output parameter information to filter the noise in the environment. And comparing whether the filtered audio waveform is matched with the waveform corresponding to the audio signal, so as to determine whether the environmental audio comprises the audio signal corresponding to the second target audio output parameter information. In the embodiment of the present application, in a case where the filtered audio waveform is matched with a waveform corresponding to the audio signal, the environmental audio includes an audio signal corresponding to the second target audio output parameter information.
Illustratively, in the case of a low power consumption voiced mode, the second target audio output parameter information includes audio frequencies in the range of 6KHz to 10 KHz. After the first terminal collects the environmental audio, a narrow-band filtering can be carried out, and only signals in the range of 6KHz to 10KHz are reserved, so that a lot of noise can be filtered, and the first terminal can conveniently identify whether the filtered environmental audio comprises the audio signals output by the second terminal.
In some embodiments, after determining that the microphone collects the audio information sent by the second terminal, distance information between the microphone and the second terminal may be determined so as to find a positional relationship between the second terminal and the first terminal.
According to the embodiment of the application, whether the environment comprises the audio sent by the second terminal or not is detected, so that high-precision direction and position judgment can be realized, and accurate positioning is provided for a user.
In some embodiments, the two microphones are a first microphone and a second microphone, respectively; referring to the above step 130, the relative position information of the first terminal and the second terminal is determined according to the distance between the two microphones and the second terminal and the distance between the two microphones, and the following steps 1301 to 1303 may be referred to.
Step 1301, acquiring a sending time of a control signal, a first time when a first microphone receives an audio signal, and a second time when a second microphone receives the audio signal;
step 1302, determining a first distance between the first microphone and the second terminal according to a preset audio propagation speed and a time difference between the emission time and the first time; determining a second distance between the second microphone and the second terminal according to a preset audio propagation speed and a time difference between the sending time and the second time;
in step 1303, the relative position information of the first terminal and the second terminal is determined according to the first distance, the second distance, and the distance between the first microphone and the second microphone.
Specifically, after the first terminal transmits the control signal, the transmission time of the control signal may be recorded, and since the transmission medium of the control signal is an electromagnetic wave, the time of transmission between the first terminal and the second terminal through the control signal may be negligible. Alternatively, by taking the emission time of the control signal as the time of the second device emitting the audio signal, the calculation process can be simplified, and the calculation speed can be increased.
Next, a first distance between the first microphone and the second terminal can be determined by combining a preset audio propagation speed and a time difference between the emission time and the first time; and determining a second distance between the second microphone and the second terminal by combining the preset audio propagation speed and a time difference between the emission time and the second time.
In some embodiments, the relative position information may include angle information and distance information, for example, the distance information may include a distance of each microphone from the second terminal, and the angle information may include an angle formed by a line between a line connecting each microphone and the second terminal and the line connecting the microphones.
By taking the example that the position of the first microphone represents the position of the first terminal, and referring to fig. 2, the distance between the first microphone and the second microphone is L0, and by combining the preset audio propagation speed and the time difference between the sending time and the first time, the first distance La between the first microphone and the second terminal and the second distance Lb between the second microphone and the second terminal can be calculated, and then, the included angle θ between the connection line between the first microphone and the second microphone and the connection line between the first microphone and the second terminal can be determined.
As a specific example, the angle θ can be found from the formulas (1) to (5). Referring to fig. 2, an intersection point of the point 12 perpendicular to the connection line between the first microphone and the second terminal is a point 13, where a distance from the point 20 where the second terminal is located to the point 13 is x, where x is an unknown quantity. The magnitude of θ can be expressed in combination with x in combination with equation (1), equation (2) and equation (3). Based on Pythagorean theorem, equation (4) can be obtained, and since L0, la and Lb are all known amounts, the calculation of x can be performed as shown in equation (5). After x is obtained, the magnitude of theta can be rapidly calculated.
cosθ*L b ＝L b -x (1)
L 0 2 -(L b -x) 2 ＝L a 2 -x 2 (4)
According to the embodiment of the application, the first terminal sends the audio signal by combining the second terminal, and the distance between the two microphones and the second terminal is determined, so that the relative position information of the first terminal and the second terminal can be rapidly and accurately determined, accurate positioning prompt information can be provided for a user, and convenience is brought to the user to find the target terminal.
In some embodiments, two pieces of relative position information may be determined by means of triangulation, and fig. 3 is a schematic diagram of a terminal artifact provided in the embodiments of the present application, specifically shown in fig. 3, where the second terminal 20 is an actual terminal, and the location of the artifact 21 is a symmetrical location of the terminal 20 based on a line where the first microphone 11 and the second microphone 12 are located. Optionally, when the microphone receives the audio signal, a plane perpendicular to the ground plane may be formed by a connection line between the first microphone and the second microphone, the space is divided into two sides, the microphone is used to detect the approximate azimuth of the sound source, the terminal on the same side as the azimuth of the sound source is the real second terminal, and then the relative position information of the first terminal and the second terminal may be determined by the triangle positioning method, so as to display the positioning guide information.
Alternatively, the second terminal and the artifact may be distinguished in conjunction with infrared distance detection, for example, the infrared distance detects that the side of the first terminal close to the wall, for example, the distance between the first terminal and the wall is less than 0.5 m, the space range corresponding to the other side of the first terminal is larger, and the nearest distance between the other side and the wall is greater than 2 m, and then the included relative position information located at the other side may be determined to be the actual terminal by the second terminal 20.
According to the embodiment of the application, the accurate positioning of the second terminal can be conveniently and rapidly realized.
In some embodiments, in order to flexibly cope with the artifact problem existing in different scenes, the real relative position information between the first terminal 10 and the second terminal 20 is accurately found.
In some embodiments, the second terminal may output a plurality of audio signals, i.e., the number of audio signals collected by each microphone is a plurality; specifically, in response to each microphone receiving an audio signal, distance information of the microphone from the second terminal is determined, and reference may be made to steps 201 and 202.
Step 201, receiving an input for controlling the movement of a first terminal;
step 202, in the moving process of the first terminal, responding to each audio signal received by each microphone, obtaining the distance between each microphone and the second terminal, and obtaining the distance information corresponding to each audio signal;
Accordingly, determining the relative position information of the first terminal and the second terminal according to the first distance, the second distance and the distance between the first microphone and the second microphone may refer to step 203 and step 204.
Step 203, corresponding to each audio signal, determining first candidate position information and second candidate position information of the second terminal according to the first distance, the second distance and the distance between the first microphone and the second microphone;
and step 20, determining relative position information in the first candidate position information and the second candidate position information according to the change trend of the first distances and the second distances, wherein the relative position information is used for indicating the actual position of the second terminal.
In an exemplary case, when the user cannot find the second terminal, the location of the second terminal is usually in a static state, and the user is often in a moving state during the process of searching for the second terminal, positioning information can be provided for the user in combination with the first terminal to assist the user in searching for the second terminal, so that the user can carry the first terminal during the moving process, and the first terminal moves in this time.
In yet another example, if the first terminal is in a stationary state, the first terminal may also output a reminder message to remind the user to move with the first terminal, so that the first terminal identifies an artifact and determines an actual location where the second terminal is located.
During the movement of the first terminal, the second terminal may output at least two audio signals, and after determining that the first terminal microphone is receiving the audio signals, the second terminal may identify a plurality of audio signals sent by the second terminal. For example, the output time interval of two adjacent audio signals may be a preset time length, and the first terminal may distinguish the two audio signals according to the receiving times corresponding to the two audio signals respectively. Based on the output time interval of two adjacent audio signals and the emission time of the control signals, the distance between the microphone and the second terminal can be conveniently calculated when the microphone receives different audio signals.

During the movement of the first terminal, the first distance between the first microphone and the second terminal changes, the second distance between the second microphone and the second terminal also changes, the corresponding direction when the first distance and the second distance are reduced can be determined as the approximate direction of the second terminal,
For example, based on the movement direction of the user, if both the first distance and the second distance become smaller during the movement of the user, the position located on the side pointed by the movement direction among the first position and the second position is the actual position of the second terminal, in other words, the angle formed by the direction in which the first terminal points to the second terminal and the movement direction is an acute angle. Based on this, can convenient and fast's realization location second terminal.
