Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a method for positioning a wireless headset according to an embodiment of the present invention is described in detail. Fig. 1 is a signaling diagram of a wireless headset positioning method according to an embodiment of the present invention, where the method includes:
s101: the wireless earphone sends a positioning request to the mobile terminal with communication connection according to preset conditions.
A mobile terminal refers to an electronic device used by a user, and the electronic device may establish a communication connection with a wireless headset. In the embodiment of the present invention, a smart phone is taken as an example for introduction.
The wireless earphones can be of various types, including infrared wireless earphones, Bluetooth wireless earphones, 2.4G wireless earphones and the like.
For convenience of description, in the embodiments of the present invention, a bluetooth wireless headset is taken as an example for description. The Bluetooth wireless earphone is provided with a Bluetooth module, and correspondingly, the mobile terminal is also provided with the Bluetooth module so as to be convenient for communication with the Bluetooth module on the wireless earphone.
The wireless headset can send positioning requests to the mobile terminal in various modes, one mode can send the positioning requests to the mobile terminal according to set frequency, and when the wireless headset is switched from a wearing state to a non-wearing state, the latest acquired positioning information is used as the initial position information of the wireless headset.
Another way may be that when the wireless headset detects that the wireless headset switches from the wearing state to the non-wearing state, a positioning request is sent to the mobile terminal with the communication connection.
Because the wireless earphone is generally used for listening to music and making a call when being worn, the wireless earphone is relatively close to the smart phone, and the positioning information of the smart phone can be regarded as the position information of the wireless earphone. Therefore, when the wireless headset detects that the wireless headset is switched from the wearing state to the non-wearing state, the wireless headset can send a positioning request to the mobile terminal with communication connection at the moment in order to acquire the initial position information of the wireless headset.
S102: and when receiving the positioning request sent by the wireless earphone, the mobile terminal sends positioning information to the wireless earphone.
In consideration of the fact that the mobile terminal is often in a moving state, in order to accurately acquire the location information of the mobile terminal, in practical applications, the mobile terminal may periodically acquire its own location information according to a set time interval.
The value of the time interval can be set according to actual requirements, for example, the time interval can be set to 1 minute, that is, the mobile terminal acquires its own positioning information every 1 minute.
When receiving the positioning request sent by the wireless headset, the mobile terminal may send the latest acquired positioning information to the wireless headset.
Taking a smart phone as an example, 2 implementations of acquiring the positioning information are provided, and one implementation manner is to acquire the positioning information of the smart phone by using a GPS positioning method under the condition that a GPS signal is good. In another mode, the positioning information of the user can be acquired by adopting a base station positioning method or an indoor WIFI positioning method indoors under the condition that the GPS signal is weak.
S103: the wireless earphone takes the received positioning information sent by the mobile terminal as initial position information.
When the wireless headset is switched from the wearing state to the non-wearing state, the positioning information of the mobile terminal can be regarded as the current position information of the wireless headset, and considering that the wireless headset can move even in the non-wearing state, the positioning information received by the wireless headset and sent by the mobile terminal can be regarded as the initial position information of the wireless headset for the convenience of distinguishing.
S104: the wireless earphone calculates the displacement information of the wireless earphone according to the information collected by the inertia measurement component.
The displacement information includes a movement distance and a movement direction. As shown in fig. 2, which is a schematic diagram of interaction between a wireless headset and a mobile terminal, the inertial measurement unit provided in the wireless headset of fig. 2 may include an acceleration sensor (G-sensor), a gyroscope, and a magnetometer. The moving distance of the wireless earphone can be calculated according to information collected by the acceleration sensor and the gyroscope; according to the information collected by the magnetometer, the moving direction of the wireless earphone can be determined.
The G-sensor may acquire X, Y, Z directional acceleration values and detect acceleration data as the headset moves. In a specific implementation, the wireless headset can judge whether the acceleration value acquired by the acceleration sensor exceeds a threshold value.
The value of the threshold may be set according to actual requirements, and is not limited herein.
When the acceleration value acquired by the acceleration sensor exceeds the threshold value, the wireless headset moves, and the moving distance of the wireless headset can be calculated according to the acceleration value, the duration of the acceleration value and the angle vector acquired by the gyroscope; and determining the moving direction of the wireless earphone according to the data acquired by the magnetometer.
When the wireless headset does not move, the acceleration value of the wireless headset can become zero, and the process from the detection of the acceleration value to the change of the acceleration value into zero is the duration of the acceleration value. The running speed of the wireless earphone can be obtained by carrying out integral operation on the acceleration value. The product of the running speed and the duration is the moving distance of the wireless earphone.
The gyroscope can compensate the angle, when the wireless earphone is moved, the gyroscope obtains initial position information when the wireless earphone is not moved, and then after the wireless earphone is moved, the gyroscope can obtain angle vectors before and after the wireless earphone is moved, so that corresponding compensation is carried out on the moving distance.
Acceleration sensor can acquire the acceleration of X, Y, Z direction, and the gyroscope can acquire the angle of X, Y, Z direction, relies on the duration of the acceleration and the angle and the acceleration value of X, Y, Z direction, can calculate wireless earphone self moving distance.
The magnetometer determines the direction of movement of the wireless headset by acquiring X, Y, Z the 3-axis data. The moving direction of the wireless headset is determined according to the data collected by the magnetometer, which belongs to the prior conventional technology and is not described herein any more.
S105: the wireless earphone transmits the displacement information to the mobile terminal.
The wireless earphone can transmit displacement information to the mobile terminal through the Bluetooth module of the wireless earphone.
S106: the mobile terminal receives displacement information transmitted by the wireless earphone; and calculating the current position information of the wireless earphone by using the positioning information and the displacement information.
The mobile terminal can receive the displacement information transmitted by the wireless earphone through the Bluetooth module of the mobile terminal.
The positioning information reflects the initial position of the wireless earphone, the displacement information reflects the mobile position of the wireless earphone, and the current position information of the wireless earphone can be determined according to the initial position and the mobile position.
S107: and the mobile terminal obtains the position relation between the mobile terminal and the wireless earphone according to the current position information of the mobile terminal and the current position information of the wireless earphone.
After the current position information of the mobile terminal and the current position information of the wireless earphone are acquired, the terminal can acquire the position relation of the mobile terminal and the wireless earphone on the graphic coordinates in a graphic coordinate mode, and a user can quickly determine the position of the wireless earphone, which is located at the mobile terminal, according to the position relation, so that the wireless earphone can be quickly searched.
After determining the position relationship between the mobile terminal and the wireless earphone, the mobile terminal can display the position relationship between the mobile terminal and the wireless earphone through an interface of the mobile terminal. The current position information of the wireless earphone can also be broadcasted in a voice broadcasting mode, or the position relation between the mobile terminal and the wireless earphone is broadcasted, for example, the direction and the distance value of the wireless earphone located at the mobile terminal are broadcasted.
According to the technical scheme, the wireless earphone sends the positioning request to the mobile terminal with communication connection according to the preset condition, and the received positioning information sent by the mobile terminal is used as the initial position information. The wireless earphone can be moved under the condition that a user is unknown, so that the position of the wireless earphone is changed, and the wireless earphone can calculate the displacement information of the wireless earphone according to the information acquired by the inertial measurement component of the wireless earphone; and transmits the displacement information to the mobile terminal. The positioning information reflects the initial position of the wireless earphone, the displacement information reflects the moving distance and the moving direction of the wireless earphone, and the mobile terminal can calculate the current position information of the wireless earphone by using the positioning information and the displacement information; and obtaining the position relation between the mobile terminal and the wireless earphone according to the current position information of the mobile terminal and the current position information of the wireless earphone. The user can determine the current position of the wireless earphone quickly through the position relation obtained by the mobile terminal, so that the wireless earphone is searched quickly, and the searching efficiency of the wireless earphone is greatly improved.
In the embodiment of the invention, the wireless earphone and the mobile terminal are in communication connection through the Bluetooth module, the communication distance of the Bluetooth module is limited, and the distance between the wireless earphone and the mobile terminal can be detected in order to ensure the normal communication between the wireless earphone and the mobile terminal.
Taking the mobile terminal as an example, the mobile terminal can calculate a relative distance value between the wireless earphone and the mobile terminal according to the current position information of the mobile terminal and the current position information of the wireless earphone; and when the relative distance value is larger than a preset threshold value, alarming and prompting.
Taking a wireless earphone as an example, after the wireless earphone calculates the displacement information of the wireless earphone according to the information collected by the inertia measurement component, the wireless earphone can calculate the current position information of the wireless earphone according to the initial position information and the displacement information; calculating a relative distance value between the wireless earphone and the mobile terminal according to the current position information of the wireless earphone and the acquired current position information of the mobile terminal; and when the relative distance value is larger than a preset threshold value, alarming and prompting.
The preset threshold value can be an upper limit value of an effective communication distance between the wireless earphone and the mobile terminal, when the relative distance value between the wireless earphone and the mobile terminal is larger than the preset threshold value, the fact that the distance between the wireless earphone and the mobile terminal is close to the effective communication range of the Bluetooth module is indicated, the wireless earphone and the mobile terminal can carry out alarm prompt at the moment, so that the attention of a user can be attracted, and the problem that the wireless earphone is inaccurate in positioning due to the fact that the distance between the wireless earphone and the mobile terminal is far is avoided.
When the wireless earphone is not worn, the requirement on the function of the wireless earphone is low, and in order to increase the endurance time of the wireless earphone, the wireless earphone can be adjusted to be in a low power consumption mode.
In a specific implementation, when receiving a positioning request sent by a wireless headset, the mobile terminal may send a low power consumption instruction to the wireless headset in addition to sending positioning information to the wireless headset, so that the wireless headset is switched to a low power consumption operating mode.
Taking a wireless earphone provided with a classic Bluetooth module (BR/EDR) and a low-power Bluetooth module (B L E) as an example, when the wireless earphone is in a wearing state, the classic Bluetooth module is in a working state, and the low-power Bluetooth module is in an idle state, and when the wireless earphone receives a low-power instruction sent by a mobile terminal, the low-power Bluetooth module can be adjusted to be in the working state and the classic Bluetooth module to be in the idle state, so that a low-power working mode of the wireless earphone is realized.
According to the change of the wearing state of the wireless earphone, the wireless earphone is adjusted to a low-power-consumption working mode when the wireless earphone is not worn, the endurance time of the wireless earphone can be effectively prolonged, and a powerful guarantee is provided for normal communication between the wireless earphone and the mobile terminal.
