Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a bluetooth headset connection control method provided in a first embodiment of the present invention, where the embodiment is applicable to a situation that a bluetooth headset is automatically disconnected from a terminal device when running of a user is completed, the method may be performed by a bluetooth headset connection control device, and the bluetooth headset connection control device may be implemented by software and/or hardware and may be configured in a bluetooth headset, where the bluetooth headset connection control method specifically includes the following steps:
s101, when the Bluetooth headset is connected with the terminal equipment, acquiring a plurality of positioning data of the terminal equipment according to a preset period.
The terminal device can be a mobile phone or other intelligent sports equipment, and the like, and the terminal device can be provided with a sports APP related to running, wherein the sports APP is used for providing music and broadcasting which are suitable for running and listening to a wearer, guiding the wearer of the Bluetooth headset to develop running, adjusting breathing and posture and the like according to guiding voice. When running, the terminal equipment is carried by a wearer, the Bluetooth earphone is connected with the terminal equipment through Bluetooth, and the exercise APP in the terminal equipment sends audio to the Bluetooth earphone through the terminal equipment.
The terminal device of the present embodiment has a positioning function, for example, a GPS system is generally provided in the terminal device. The positioning data is the position data monitored by the GPS system. The preset period is a period for collecting positioning data and may be a short length of time, for example 10 seconds.
S102, judging whether a wearer of the Bluetooth headset is in a running state or not according to the plurality of positioning data.
For the runner, generally, the runner does not reciprocate in a short time, in this embodiment, the positioning data of the wearer in the preset period is mainly considered to be continuously changed, and when the wearer of the bluetooth headset is in the running state, the position of the wearer in the preset period is usually continuously changed, so that whether the terminal device is in the moving state can be judged through a plurality of positioning data, if so, the wearer is determined to be in the running state, and S103 is executed, if not, whether the wearer is in the running state is continuously monitored.
Specifically, whether the terminal equipment is in a moving state is judged through a plurality of positioning data, the displacement corresponding to the positioning data of two adjacent sampling times can be calculated first, and if the displacement is not 0, the wearer can be determined to be in the moving state.
In addition, an acceleration sensor can be arranged on the terminal equipment or the Bluetooth headset, and whether the wearer is in a moving state or not can be judged by combining acceleration data acquired by the acceleration sensor.
S103, calculating the target distance between the Bluetooth headset and the terminal equipment through Bluetooth signal intensity.
The terminal equipment is used as a transmitting end, the communication Bluetooth headset is used as a receiving end, and the Bluetooth signal intensity of the transmitting end and the Bluetooth signal intensity of the receiving end are inversely proportional to the distance between the transmitting end and the receiving end, namely, the closer the distance is, the stronger the Bluetooth signal intensity is, the farther the distance is, and the weaker the Bluetooth signal intensity is.
The formula for calculating the target distance d is:
d＝10^((abs(rssi)-A)/(10*n))
where rsti is bluetooth signal strength, a is signal strength when the transmitting end and the receiving end are separated by 1 meter, n is an environmental attenuation factor, and abs (rsti) represents taking an absolute value for rsti.
In practical situations, the interference suffered during the transmission is relatively large, so the RSSI value is generally smaller than 0, for example, the RSSI of the bluetooth headset is stronger than the signal strength of the RSSI of-100 dBm, and the corresponding target distance is closer.
Furthermore, the acquisition conditions of the target distance may be: when one positioning data is acquired, the target distance between the Bluetooth headset and the terminal equipment can be calculated through the Bluetooth signal intensity.
S104, judging whether the Bluetooth headset is in a non-wearing state according to the plurality of target distances.
When a wearer runs with the Bluetooth headset, the terminal device is usually placed in a waist bag, an arm bag or held on a hand, the distance between the Bluetooth headset and the terminal device is relatively fixed, and if the wearer takes down the headset, the target distance is greatly changed, so that after the target distance between the Bluetooth headset and the terminal device is calculated, whether the Bluetooth headset is in a non-wearing state can be judged according to a plurality of target distances, if yes, S105 is executed, if not, whether the Bluetooth headset is in the non-wearing state is continuously monitored, specifically, whether the difference value between the adjacent target distances is in a preset difference value range can be judged, and if yes, the Bluetooth headset is in the non-wearing state can be determined.
In addition, a bio-impedance sensor can be further arranged on the Bluetooth headset, and the bio-impedance sensor is used for detecting and obtaining human body parameters, wherein the human body parameters comprise at least one of a skin electric reaction index, a bio-resistor, a heartbeat frequency and a respiratory rate. Whether the Bluetooth headset is in a non-wearing state or not is judged by combining the target distance and the human body parameters, and the Bluetooth headset can be detected more accurately when the Bluetooth headset is in the non-wearing state.
S105, sending a disconnection message to the terminal equipment.
When the Bluetooth headset is in a non-wearing state, the Bluetooth headset is difficult to hear the audio sent by the Bluetooth headset, and the Bluetooth headset and the terminal equipment are still in a connection state at the moment, if other audio information is sent at the moment, a user cannot know and miss the audio information, for example, a call dialed by a family friend or a short message sent by the family friend, so that the Bluetooth headset sends a disconnection message to the terminal equipment, the terminal equipment stops connecting with the Bluetooth headset when receiving the disconnection message, switches an audio playing channel to a loudspeaker for playing, and can remind the user to confirm through the loudspeaker when receiving the information sent by other terminals.
The embodiment of the invention provides a Bluetooth headset connection control method, which is characterized in that when a Bluetooth headset is connected with terminal equipment, a plurality of positioning data of the terminal equipment are acquired according to a preset period, whether a wearer of the Bluetooth headset is in a running state or not is judged according to the plurality of positioning data, a target distance between the Bluetooth headset and the terminal equipment is calculated through Bluetooth signal intensity when the wearer is in the running state, whether the Bluetooth headset is in a non-wearing state or not is judged according to the plurality of target distances, a disconnection message is sent to the terminal equipment when the Bluetooth headset is in the non-wearing state, the terminal equipment stops being connected with the Bluetooth headset when the disconnection message is received, and an audio playing channel is switched to a loudspeaker for playing. Whether the Bluetooth headset is in a wearing state after the wearer is in a running state or not is monitored through the positioning data and the target distance, and when the Bluetooth headset is in a non-wearing state, the terminal equipment is informed to be disconnected with the Bluetooth headset and is switched to a loudspeaker playing mode, so that information sent by other terminals is prevented from being missed, and intelligent switching between playing of the Bluetooth headset and playing of the loudspeaker is realized.
Example two
Fig. 2 is a flowchart of a bluetooth headset connection control method according to a second embodiment of the present invention, where the method is further optimized based on the foregoing embodiment, and specifically includes the following steps:
S201, when the Bluetooth headset is connected with the terminal equipment, acquiring a plurality of positioning data of the terminal equipment according to a preset period.
S202, judging whether a wearer of the Bluetooth headset is in a running state or not according to the plurality of positioning data. If yes, S203 is executed.
S203, calculating the target distance between the Bluetooth headset and the terminal equipment through Bluetooth signal intensity.
Since S201 to S203 are the same as those of the first embodiment, reference is made to the description of a part of the first embodiment, and a detailed description is omitted here.
And S204, adding the target distance to the head of the sliding window with the preset length when one target distance is obtained through calculation, and calculating a first average value of a plurality of target distances in the sliding window.
Fig. 3 shows the positional relationship of data of the sliding window under different time, as shown in fig. 3, the preset length of the sliding window is set to 8, the head position of the sliding window is the position of the serial number 1, 301 is the sliding window of the previous time, 302 is the sliding window of the current time, compared with the sliding window 301, the latest target distance (0.4) is newly added in 302 to the head position of the sliding window, the data of serial numbers 1-7 in the original 301 is shifted forward from serial number 2 in the sliding window 302, and because the data amount in the sliding window is kept unchanged, the target distance (0.5) of the serial number 8 in the original 301 is removed, so that the updated sliding window is obtained, and the transmission and updating of the sliding window to the target distance are reflected. Of course, the data size of the sliding window in this embodiment may be determined according to practical situations, for example, the preset length of the sliding window may be 50, which is not limited by the present application.
And calculating the average value of the target distances in the current sliding window as a first average value.
S205, calculating an absolute value of a difference value between the first mean value and the second mean value. The second average is the average calculated last time the target distance was added to the sliding window head.
For the sliding window 302 of the current time in fig. 3, the average value of the data included in the sliding window 301 is the first average value, and the average value of the data included in the sliding window 302 is the second average value.
And calculating the absolute value of the difference between the first mean value and the second mean value, wherein the difference factor of the first mean value and the second mean value is from the newly increased target distance and the last target distance in the sliding window at the previous time.
When the wearer wears the earphone in continuous time, the Bluetooth earphone is located at the ear of the wearer, the terminal equipment is generally located at fixed positions such as a hand, a waist pack and an arm pack, the target distance value between the Bluetooth earphone and the terminal equipment is stable, and even if a target distance is newly added in the sliding window, the difference between the first average value and the second average value of the target distances in the sliding window is small. If the wearer takes down the bluetooth headset, the headset is usually held in the hand or put in a position close to the terminal device such as a waist pack and an arm pack, that is, when the bluetooth headset is in a non-wearing state, the difference between the target distance value and the target distance value is larger than that in a wearing state, so for the sliding window, if the data of the previous time are the target distance for wearing the bluetooth headset and the newly added data are the target distance for taking down the bluetooth headset, the difference between the current first average value and the second average value is larger.
S206, judging whether the absolute value is larger than a preset average value. If yes, executing S207, if not, continuing to detect whether the absolute value is larger than the preset average value.
S207, determining that the Bluetooth headset is in a non-wearing state.
The preset average value is used for measuring the degree of differentiation of the first average value and the second average value, and is further used for judging whether the newly added target distance of the Bluetooth headset is different from the data in the previous state, and when the absolute value is larger than the preset average value, the newly added target distance data of the latest sliding window is represented as the data of the Bluetooth headset in the non-wearing state because the Bluetooth headset is originally in the wearing state.
In one example of the present embodiment, when the absolute value is greater than the preset average value, the method further includes: when the terminal equipment runs the preset application program, judging whether the preset application program plays preset voice, if so, determining that the Bluetooth headset is in a non-wearing state.
The terminal device can be provided with a preset application program, such as a certain exercise APP, the exercise APP can provide guiding voice for a wearer to develop running, adjust breathing and gesture, and the like, a certain running item can be generally selected on the exercise APP by a user and the user clicks to start exercise, then running is started according to the prompt and the guidance of the exercise APP, the preset voice indicates that the running item of the exercise APP is completed, and when the Bluetooth headset receives the preset voice, the user can be judged to finish running. In this example, when it is determined that the user takes down the bluetooth headset, it is determined that running is finished from the user's perspective, and when it is determined that the preset application program makes a preset voice, that is, it is determined that running is stopped from the preset application program perspective, and the user's movement state is determined from two perspectives, the accuracy of determining the user's movement state can be improved.
S208, sending a disconnection message to the terminal equipment, stopping the connection with the Bluetooth headset when the terminal equipment receives the disconnection message, and switching the audio playing channel to a loudspeaker for playing.
When the Bluetooth earphone is in a non-wearing state, the Bluetooth earphone is difficult to hear the audio sent by the Bluetooth earphone, and the Bluetooth earphone and the terminal equipment are still in a connection state at the moment, if other audio information is sent at the moment, a user cannot know and miss the audio information, so that the Bluetooth earphone sends a disconnection message to the terminal equipment, the terminal equipment stops being connected with the Bluetooth earphone when receiving the disconnection message, switches an audio playing channel to a loudspeaker for playing, and can remind the user to confirm through the loudspeaker when receiving the information sent by other terminals.
