Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The earphone anti-loss technology of the embodiment is proposed based on a wireless earphone of the binaural ear, and the earphone is provided with a charging box for replenishing the electric quantity, as shown in fig. 1 and fig. 2. In order to realize the anti-lost function of the earphone, the left earphone and the right earphone are respectively provided with a control module, and a distance measuring module, a wireless communication module, an alarm module and other main components which are correspondingly connected with the control module; and a main control unit, a distance measuring unit, a wireless communication unit, an alarm unit and other functional circuits which are correspondingly connected with the main control unit are arranged in the charging box used in a set.
On one side of the headset, as shown in fig. 1, the distance measuring modules arranged in the left and right headsets are used for detecting the distance between the left and right headsets on one hand, and are used for matching with the distance measuring unit arranged in the charging box on the other hand, so as to complete the distance detection between the charging box and the left and right headsets. As a preferred design of this embodiment, the distance measuring module preferably uses a distance measuring sensor designed based on microwave technology, and calculates the distance between the transmitter and the receiver according to the connection time of the transmitter and the receiver. Because the signal transmitted between the transmitter and the receiver is a microwave signal with medium penetration characteristics, the effective measurement of the distance can be realized no matter whether a shielding object exists between the two earphones or between the two earphones and the charging box.
In the left and right earphones, the wireless communication module is arranged to provide double insurance of earphone anti-lost detection when the distance measurement is misaligned or fails. Specifically, the left and right earphones can establish wireless data connection between the two earphones through the wireless communication module, and whether the distance between the two earphones exceeds the effective receiving range of the radio frequency signal is judged according to the connection state. The effective propagation distance of the rf signal should be limited to a short range, for example, within 5 meters or within 10 meters, so that when the headset is exposed to a potential loss risk, the system can respond in time to remind the user to confirm the safety of the headset as soon as possible. Similarly, the left earphone and the right earphone are configured to be respectively connected with the charging box through the wireless communication module in a wireless data mode, and then whether the distance between the charging box and the two earphones exceeds the effective receiving range of the radio frequency signals or not is judged according to the connection state, so that whether the charging box and the two earphones are in risk of loss or not is judged.
In the left and right earphones, the control module receives the distance signals detected by the distance measuring module to generate a distance value between the earphones and the charging box and a distance value between the two earphones, and compares the distance values with a safety distance S written in the control module in advance to generate a distance detection result. Meanwhile, the control module establishes wireless connection with the opposite earphone and the charging box through the wireless communication module, and generates a connection detection result according to the connection state. When the control module detects that the distance between the earphone and the charging box or the distance between the two earphones exceeds the set safe distance S, or when the control module detects that the earphone is disconnected with the charging box or the two earphones, an alarm is triggered, for example, an alarm signal is generated and sent to the alarm module to remind a user of paying attention.
In this embodiment, the alarm modules disposed on the left and right earphones preferably adopt an audible and visual alarm mode, and specifically include a speaker and an indicator light, and the control module controls the speaker to play a prompt voice and controls the indicator light to light up, so as to trigger the alarm function of the earphones.
Considering that the user is very easy to lose the earphones during the period of wearing the earphones to perform sports, and once the earphones fall off, the user is very easy to lose a long distance instantly, in order to improve the anti-loss effect of the earphones, the embodiment preferably further adds acceleration sensors G-sensors in the left and right earphones to connect the control module. After the earphone starts the anti-loss function, the acceleration sensor G-sensor is powered on to operate, the motion state of a wearer of the earphone is detected, an acceleration detection signal is generated, and the acceleration detection signal is sent to the control module. The control module can compare the detected acceleration signal with a set threshold, if the detected acceleration signal does not exceed the set threshold, the control module configures the ranging module to measure the distance at a normal frequency (for example, 1-2 times per second), and compares the measured distance value with a set safe distance S (for example, 3-5 meters), so as to generate a judgment result of whether the earphone is lost or not by matching with the connection state detection result. On the contrary, if the detected acceleration signal exceeds the set threshold, the headset is considered to be in a fast moving state, and at this time, the control module is preferably configured to decrease the safety distance set value S, for example, adjust S to 1-2 meters, and increase the ranging frequency of the ranging module, for example, adjust to 2-3 times per second, so as to increase the sensitivity of distance detection.
On the charging box side, as shown in fig. 2, the distance measuring unit is used to detect the distance between the charging box and the left earphone and the distance between the charging box and the right earphone. As a preferred design of this embodiment, a left distance measuring module L used in match with the distance measuring module in the left earphone and a right distance measuring module R used in match with the distance measuring module in the right earphone may be respectively disposed in the distance measuring unit. Both ranging modules R, L preferably employ microwave ranging sensors to support the penetration ranging function.
In the charging box, a wireless communication unit is used for detecting a connection state between the charging box and two earphones. As a preferable configuration of the present embodiment, a left wireless communication module L 'used in cooperation with the wireless communication module in the left earphone and a right wireless communication module R' used in cooperation with the wireless communication module in the right earphone may be provided in the wireless communication unit, respectively. The effective distance between the two wireless communication modules R ', L' for receiving and transmitting the radio frequency signal is preferably set within a short range, for example, within 5 meters or within 10 meters, so as to ensure the anti-lost detection effect.
In the charging box, the main control unit is used for receiving the distance signals detected by the left distance measuring module L and the right distance measuring module R, respectively generating a distance value from the charging box to the left earphone and a distance value from the charging box to the right earphone, comparing the distance values with a safety distance S' written in the main control unit in advance, and then generating a distance detection result. In this embodiment, the safe distance S' may be equal to or different from the safe distance S preset in the earphone, and may be determined according to actual needs. During the distance measurement of the charging box, the main control unit establishes wireless connection with the left earphone through the left wireless communication module L ', establishes wireless connection with the right earphone through the right wireless communication module R', and respectively generates a connection detection result between the charging box and the left earphone and a connection detection result between the charging box and the right earphone according to the connection state. When the main control unit detects that the distance between the charging box and any one earphone exceeds the set safe distance S', or when the main control unit detects that the charging box is disconnected with any one earphone, an alarm is triggered, for example, an alarm signal is generated and sent to the alarm unit, so that the user is warned.
In this embodiment, the alarm unit disposed on the charging box preferably adopts an alarm mode of sound + light + vibration, and specifically, a buzzer, a flashlight and a vibrator may be disposed in the alarm unit. When the main control unit triggers the alarm, the buzzer is controlled to buzz, the flash lamp is controlled to flicker, the vibrator is controlled to drive the charging box to vibrate, the alarm is reminded to a user from different senses, and the user can conveniently find the alarm.
In consideration of the fact that the probability of the loss of the charging box or the earphone during the physical exercise of the user is high, in order to improve the loss prevention effect of the earphone and the charging box, the present embodiment preferably further adds an acceleration sensor G-sensor' in the charging box, and connects the main control unit. After the charging box starts the anti-loss function, the acceleration sensor G-sensor' is electrified and operated to detect the motion state of a carrier of the charging box, generate an acceleration detection signal and send the acceleration detection signal to the main control unit. The main control unit may compare the detected acceleration signal with a set threshold to determine whether the charging box is in a fast moving state.
In this embodiment, it is preferable that the main control unit obtains the motion states of the left and right earphones through the wireless communication unit, and if the two earphones are in a fast motion state, or the two earphones are in a stationary or steady motion state, and the charging box is in a fast motion state, or both the two earphones and the charging box are in a fast motion state, the main control unit sets the ranging frequency of the left ranging module L and the right ranging module R to be increased (for example, from 1-2 times per second to 2-3 times per second), and decreases the safe distance setting value S' (for example, from 3-5 meters to 1-2 meters), so as to improve the sensitivity of the charging box to the distance detection of the two earphones. If only one earphone is in a fast motion state, for example, the left earphone (or the right earphone) is in a fast motion state, and the charging box and the other earphone are in a static or steady motion state, for example, the right earphone (or the left earphone) is in a static or steady motion state, the main control unit may only set the left ranging module L (or the right ranging module R) to increase the ranging frequency, and reduce the safe distance setting value from the charging box to the left earphone (or the right earphone), and keep the ranging frequency from the right ranging module R (or the left ranging module L) and the safe distance setting value from the charging box to the right earphone (or the left earphone) unchanged, so as to increase the sensitivity of the charging box to the distance detection of the left earphone (or the right earphone).
In order to further achieve the purpose of energy saving and consumption reduction, an earphone insertion detection unit may be further disposed in the charging box, and insertion detection modules are respectively disposed in the left earphone and the right earphone, as shown in fig. 1 and fig. 2. The earphone insertion detection unit arranged in the charging box can respectively detect the plugging state of the left earphone and the plugging state of the right earphone, and respectively generate plugging detection signals to be sent to the main control unit. When detecting that one of the earphones is pulled out of the charging box, the main control unit starts the anti-loss function, controls the charging box to be electrically operated with the ranging module and the wireless communication module which are matched with the earphones, respectively detects the distance and the connection state between the charging box and the earphones, and prevents the charging box and the earphones pulled out of the charging box from being lost. By adopting the design, the problem that the accuracy of the anti-loss detection result is influenced due to the fact that the distance between the earphone with the built-in charging box and the charging box is very close and the possible distance measurement failure or connection failure occurs can be solved.
When the main control unit detects that the two earphones are all pulled out of the charging box, the two distance measuring modules R, L and the two wireless communication modules R 'and L' in the charging box are started to be powered on and run, and when any earphone exceeds a safe distance relative to the charging box or any earphone is disconnected with the charging box, an alarm is triggered.
For the left earphone and the right earphone, the control module in the earphone recognizes the plugging state of the earphone relative to the charging box according to the plugging detection module arranged in the earphone, and controls the distance measuring module and the wireless communication module in the earphone to be powered on and run only under the condition that the charging box is plugged out of the earphone, so that the loss prevention function is started. If only one earphone is pulled out of the charging box, for the earphone pulled out of the charging box, the control module can be communicated with the charging box through the wireless communication module so as to acquire the plugging and unplugging state of the earphone of the other party relative to the charging box. If the charging box is not pulled out of the earphone of the other party, the earphone pulled out of the charging box is only matched with the charging box, distance detection and connection state detection between the earphone and the charging box are carried out, and distance measurement and connection detection with the earphone of the other party are not carried out any more.
The following describes in detail a specific design flow of the earphone anti-lost method according to this embodiment with reference to fig. 3 and 4.
Fig. 3 shows a situation where both earphones are pulled out of the charging box, including the following processes:
s301, the charging box detects the plugging and unplugging states of the two earphones and generates left earphone plugging and unplugging state data and right earphone plugging and unplugging state data;
in this embodiment, the charging box may utilize a built-in earphone plug-in detection unit to respectively detect plug-in and plug-out states of two earphones on the charging box, and generate left earphone plug-in and plug-out state data and right earphone plug-in and plug-out state data in combination with a main control unit (e.g., a single chip microcomputer, etc.).
S302, detecting the motion state of the charging box by the charging box;
in this embodiment, after the charging box detects that any earphone is pulled out of the charging box, the acceleration sensor G-sensor' is activated to detect the acceleration of the charging box, and the detected acceleration is compared with the set threshold. If the charging box does not exceed the set threshold, the charging box carrier is considered to be in a static or stable motion state; if the set threshold value is exceeded, the charging box carrier is considered to be in a rapid movement state.
S303, after the charging boxes are pulled out of the two earphones, detecting the motion state of the earphones, and generating motion state data;
the left earphone and the right earphone can identify whether the charging box is pulled out or not by using the self-configured insertion detection module, and after the charging box is pulled out, the self-configured acceleration sensor is started to detect the acceleration of the earphone and transmit the acceleration to the control unit to be compared with a set threshold value, so that motion state data of the earphone, such as state data representing rapid motion or stable motion, is generated.
S304, detecting the connection state among the charging box, the left earphone and the right earphone, and triggering an alarm when any two earphones are disconnected;
in this embodiment, the charging box starts its wireless communication unit to establish wireless data connection with the wireless communication modules in the left earphone and the right earphone, respectively, and detects the connection state. Meanwhile, wireless data connection between the earphones is also established between the left earphone and the right earphone through the wireless communication module, and the connection state is detected.
As a preferred design of this embodiment, when detecting the connection state between the charging box and the left earphone, the charging box preferably sends the right earphone plugging state data to the left earphone at regular time, and receives the left earphone motion state data fed back by the left earphone within a specified time. Similarly, when detecting the connection state between the charging box and the right earphone, the charging box preferably sends the left earphone plugging state data to the right earphone at regular time, and receives the right earphone motion state data fed back by the right earphone within the specified time. And if response data fed back by the two earphones, such as motion state data, is received within a specified time, the charging box and the two earphones are judged to be in a connected state. If the response data fed back by one earphone or two earphones is not received within the specified time, the charging box is judged to be disconnected with the earphones, and the charging box triggers an alarm. In this case, for the earphone disconnected from the charging box, the earphone side does not receive the plugging and unplugging state data of the earphone of the other party sent by the charging box within the specified time, so the earphone side can trigger the alarm in time, and the search by the user is facilitated.
When the connection state between the two earphones is detected by the left earphone and the right earphone, the motion state data of the earphones are preferably interacted, and if the motion state data fed back by the other earphone is received within the specified time, the two earphones are considered to be in the connection state; otherwise, both earphones are considered to be in the off state.
By adopting the above design mode, the data interaction process can be completed while the connection state detection is realized, so that the charging box can know the motion states of the two earphones, and any one earphone can know the plugging state of the other earphone relative to the charging box and the motion state of the other earphone, so as to facilitate the proceeding of the subsequent flow.
S305, setting a safe distance and a ranging frequency;
on the charging box side, if the charging box and both earphones are in a stationary or stationary state, the safe distance set value S' in the charging box is set to a normal value, for example, 3-5 meters, and the ranging frequency of the ranging unit in the charging box is configured to a normal frequency, for example, 2-3 times per second. If the charging box is in a fast movement state or any one earphone is in a fast movement state, the safety distance set value S' in the charging box is reduced to 1-2 meters, for example, and the distance measuring frequency of the distance measuring unit in the charging box is increased to 1-2 times per second, for example, so as to improve the sensitivity of anti-lost detection.
On the earphone side, if both earphones are in a static or stable motion state, setting a safety distance set value S in the earphones as a normal value, and configuring the ranging frequency of a ranging module in the earphones as a normal frequency; if the earphone of the earphone is in a rapid movement state or the earphone of the other side is in a rapid movement state, the set value S of the safe distance in the earphone is reduced, and the distance measuring frequency of the distance measuring module in the earphone is improved.
S306, detecting the distance between the charging box and the left earphone and the distance between the charging box and the right earphone, and triggering an alarm when the distance between any two earphones exceeds a set safe distance;
and on the side of the charging box, the main control unit controls the distance measuring unit to respectively measure the distance from the charging box to the left earphone and the distance from the charging box to the right earphone, and if the distance between one earphone and the charging box exceeds a set safety distance value S', the charging box triggers an alarm.
On the earphone side, the control modules in the left earphone and the right earphone respectively control the distance measuring modules to detect the distance between the two earphones and the distance from the earphones to the charging box, and when the distance between the earphones and the charging box exceeds a set safety distance value S', or the distance between the two earphones exceeds the set safety distance value S, the earphones trigger alarm.
From this, the anti-lost function of charging box and left and right earphone has been realized.
Fig. 4 shows a case where the left earphone is pulled out of the charging box and the right earphone is inserted into the charging box, including the following processes:
s401, the charging box detects the plugging and unplugging states of the two earphones and generates left earphone plugging and unplugging state data and right earphone plugging and unplugging state data;
in this embodiment, the left earphone plugging status data is the status data corresponding to the left earphone plugging charging box, and the right earphone plugging status data is the status data corresponding to the right earphone plugging charging box.
S402, detecting the motion state of the charging box by the charging box;
this step may follow the description related to step S302.
S403, after the charging box is pulled out of the left earphone, detecting the motion state of the left earphone and generating motion state data;
in this embodiment, because the charging box is not pulled out of the right earphone, the anti-lost function of the right earphone is preferably not started, and the problem of distance measurement failure or connection failure between the right earphone and the charging box is avoided while energy conservation and consumption reduction are realized.
S404, detecting the connection state between the charging box and the left earphone, and triggering an alarm when the charging box and the left earphone are disconnected;
in this embodiment, the charging box starts the left wireless communication module L' to periodically send the right earphone plugging status data to the left earphone, and receives the left earphone motion status data fed back by the left earphone within a specified time. And if the motion state data fed back by the left earphone is received within the specified time, judging that the charging box and the left earphone are in a connected state, and executing the subsequent steps. If the motion state data fed back by the left earphone is not received within the specified time, the charging box is judged to be disconnected with the left earphone, and the charging box triggers an alarm. In this case, the left earphone does not receive the right earphone plug-pull state data sent by the charging box within the predetermined time, so the left earphone can trigger an alarm in time to end the process.
S405, setting a safety distance and a ranging frequency;
and the charger determines a set value S' of the safe distance and configures the distance measuring frequency of the distance measuring module according to the motion states of the charger and the left earphone. The specific determination method of the safe distance setting value S' and the ranging frequency may follow the related description in step S305.
S406, detecting the distance between the charging box and the left earphone, and triggering an alarm when the distance between the charging box and the left earphone exceeds a set safety distance value S';
in this embodiment, the charging box detects the distance between the charging box and the left earphone through the cooperation of the left distance measuring module L and the distance measuring module in the left earphone.
