The embodiment of the present disclosure provides an anti-lost device 200, as shown in fig. 1, the anti-lost device 200 includes a bluetooth module 201 and a processor 202, and the anti-lost device 200 is configured to perform bluetooth communication with a headset assembly 100 including a first headset 110 and a second headset 120 by using the bluetooth module 201.
The following description will be given by taking an example in which the operation flow of detecting the bluetooth connection condition and the loss judgment is executed on the anti-lost device 200 side, and such an anti-lost device 200 can be used in cooperation with a general bluetooth headset assembly 100 to implement an anti-lost function. However, it is understood that the operations of detecting the bluetooth connection condition and determining the loss may be performed on the earphone assembly 100 side, and any device with bluetooth function may be used as the anti-loss device 200 in cooperation with such an earphone assembly 100 to implement the anti-loss function.
The bluetooth module 201 of the anti-lost device 200 is configured to: detecting a bluetooth connection of the anti-lost device 200 with the earphone assembly 100 (S210), and determining a Received Signal Strength Indication (RSSI) of the anti-lost device 200; the processor 202 of the anti-lost device 200 is configured (as shown in fig. 2): in a case where the anti-lost device 200 maintains bluetooth connections with both the first earphone 110 and the second earphone 120 (S211), determining a representative value of RSSI of both bluetooth connections (S212) and determining whether or not it is less than a first threshold (S213), and if so, determining that the anti-lost device 200 is lost (S214); in the case where the anti-lost device 200 maintains the bluetooth connection with the first earphone 110 or the second earphone 120 (S221), a representative value of RSSI of the bluetooth connection is determined (S222) and it is determined whether or not it is less than a second threshold value (S223), and if so, it is determined that the anti-lost device 200 is lost (S224).
It will be appreciated that the anti-lost device 200 may be placed with other items that can communicate with its bluetooth to enable timely confirmation that an item is lost when an item that communicates with the anti-lost device 200 bluetooth is lost. The embodiment of the present disclosure takes bluetooth communication between the anti-lost device 200 and the earphone assembly 100 as an example, and through the bluetooth communication between the anti-lost device 200 and the earphone assembly 100, it can be mutually confirmed whether the other side is lost. Therefore, the anti-lost function can be realized under the condition that the Bluetooth headset can be worn and the Bluetooth connection with at least one Bluetooth headset is kept for a certain time; the first threshold value and the second threshold value are respectively set for the condition that the anti-lost device 200 is in Bluetooth connection with two earphones 110 and 120 and the condition that the anti-lost device is in Bluetooth connection with only one earphone, and compared with the prior art that the anti-lost device is judged only when the Bluetooth connection is disconnected, the anti-lost device 200 can be sensitively detected to realize lower false alarm rate.
It is understood that the bluetooth module 201 of the anti-lost device 200 can detect the bluetooth connection condition with the earphone assembly 100 and the Received Signal Strength Indication (RSSI) of the anti-lost device 200, and when the anti-lost device 200 maintains the bluetooth connection with both the first earphone 110 and the second earphone 120, the processor 202 of the anti-lost device 200 can determine whether the anti-lost device 200 is lost by determining the representative value of the RSSI of the bluetooth connection and determining whether the anti-lost device 200 is lost, that is, when the representative value of the RSSI of the bluetooth connection is smaller than the first threshold value, the anti-lost device 200 is lost.
In the case where the anti-lost device 200 maintains the bluetooth connection with only one of the first earphone 110 and the second earphone 120, the processor 202 of the anti-lost device 200 can determine whether the anti-lost device 200 is lost by determining the representative value of the RSSI of the bluetooth connection and determining whether the representative value of the RSSI of the bluetooth connection is smaller than the second threshold, that is, when the representative value of the RSSI of the bluetooth connection is smaller than the second threshold, it is determined that the anti-lost device 200 is lost.
According to the anti-lost device 200, the Bluetooth module 201 of the anti-lost device 200 is used for detecting the Bluetooth connection condition of the anti-lost device 200 and the earphone assembly 100 and the Received Signal Strength Indicator (RSSI) of the anti-lost device 200, whether the anti-lost device 200 is lost or not is further judged, and the anti-lost function of the anti-lost device 200 in Bluetooth communication with the earphone assembly 100 is realized.
In some embodiments, the anti-lost device 200 is further configured to: in case the loss preventer 200 is lost, an alert audio signal is sent to the earphone assembly 100 to notify a user via the earphone assembly 100.
It is understood that after determining that the anti-lost device 200 has been lost by the processor 202 of the anti-lost device 200, the anti-lost device 200 can send a prompt audio signal to the earphone assembly 100, so that the earphone assembly 100 informs the user that the anti-lost device 200 is lost, to remind the user that the earphone assembly 100 is not lost.
In some embodiments, the bluetooth module 201 of the anti-lost device 200 is further configured to: determining the interfered related information of each frequency point of the anti-lost device 200; as shown in fig. 3 (a), the anti-lost device 200 further includes a memory 203, the memory 203 of the anti-lost device 200 is configured to: storing the determined information related to the interference of each frequency point of the anti-lost device 200 under the condition that the anti-lost device 200 keeps Bluetooth connection with each earphone (S301 or S302);
the processor 202 of the anti-lost device 200 is further configured to: when the anti-lost device 200 disconnects the bluetooth connection to both the first earphone 110 and the second earphone 120, it is determined whether the anti-lost device 200 is lost based on the information related to interference at each frequency point of the anti-lost device 200 before disconnection.
It can be understood that, due to factors affecting the bluetooth disconnection between the two earphones and the anti-lost device 200, besides the distance between the earphone assembly 100 and the anti-lost device 200 is too large, there is also a case where the environmental interference where the anti-lost device 200 is located is too large, which causes the bluetooth disconnection between the anti-lost device 200 and the earphone assembly, for example, the anti-lost device 200 is located in a place with a great flow of people, such as a train station, an airport, and a concert, and at this time, the bluetooth disconnection between the anti-lost device 200 and the two earphones does not represent that the anti-lost device 200 is lost. By storing the interfered related information of each frequency point at a certain moment before the disconnection between the two earphones and the anti-lost device 200 or a certain time period before the disconnection in the memory 203 of the anti-lost device 200, whether the disconnection between the anti-lost device 200 and the two earphones is caused by excessive environmental interference can be further determined (S303), so that whether the anti-lost device 200 is lost or not can be more accurately determined, and a lower false alarm rate can be obtained.
It can be understood that the interfered related information of each frequency point includes the available frequency points in the hopping list and/or the RSSI of the air interference signals of each frequency point, that is, by determining the interfered related information of each frequency point, the number of available frequency points in the hopping list can be determined (S311) and the RSSI of the air interference signals of each frequency point can be determined (S321).
Further, determining whether the anti-lost device 200 is lost based on the information related to interference of the two earphones at each frequency point before the bluetooth connection is disconnected comprises: when the number of available frequency points in the frequency hopping table is greater than a third threshold value (S312), determining that the anti-lost device 200 is lost (S313); and/or determining that the anti-lost device 200 is lost (S323) when the RSSI of the air interference signal of the frequency bin of the fourth threshold value is less than the fifth threshold value (S322).
It can be understood that, before both of the two earphones are disconnected from the anti-lost device 200 by bluetooth, the number of available frequency points in the frequency hopping list stored in the memory 203 of the anti-lost device 200 exceeds the third threshold, and/or the RSSI of the air interference signal of a certain number of frequency points is smaller than the fifth threshold, which indicates that the interference suffered by both of the two earphones before disconnection from the anti-lost device 200 is small, and the environmental interference does not cause disconnection between both of the earphones and the anti-lost device 200, so it is determined that the bluetooth disconnection is caused only when the anti-lost device 200 is lost, that is, the result is determined that the anti-lost device 200 is lost.
The embodiment of the present disclosure also provides a wireless communication system, which includes the above-mentioned anti-lost device 200 and the earphone assembly 100. The loss preventer 200 and the earphone set 100 in the wireless communication system perform bluetooth communication, and it is possible to confirm whether the loss preventer 200 is lost through the bluetooth module 201 and the processor 202 of the loss preventer 200. Specifically, the bluetooth module 201 of the anti-lost device 200 is configured to: detecting a bluetooth connection of the anti-lost device 200 with the headset assembly 100 and determining an RSSI of the anti-lost device 200; the processor 202 of the anti-lost device 200 accordingly confirms whether the anti-lost device 200 is lost by using the representative value of the RSSI of the bluetooth connection based on the bluetooth connection between the anti-lost device 200 and the first earphone 110 and the second earphone 120 in the earphone assembly 100, so that the anti-lost device 200 in the wireless communication system has an anti-lost function.
As described above, the operations of detecting the bluetooth connection condition and determining the loss may be performed on the headset assembly 100 side, and the specially designed headset assembly 100 will be described below. With continued reference to fig. 1, a headset assembly 100 includes a first headset 110 and a second headset 120, each headset including a bluetooth module 101 and a processor 102, the headset assembly 100 configured for bluetooth communication with an anti-lost device 200 using the bluetooth module 101.
Further, the bluetooth module 101 of each headset is configured to: detecting a bluetooth connection of the headset to the anti-lost device 200 (S210), and determining a Received Signal Strength Indication (RSSI) of the headset for the bluetooth connection. The processor 102 of the first earpiece 110 or the second earpiece 120 is configured (as shown in fig. 2): in a case where the first and second earphones 110 and 120 and the loss preventer 200 maintain the bluetooth connection (S211), determining a representative value of RSSI of both bluetooth connections (S212) and determining whether or not it is less than a first threshold (S213), and if so, determining that the loss preventer 200 is lost (S214); and in the case where the first headset 110 or the second headset 120 maintains the bluetooth connection with the anti-lost device 200 (S221), determining a representative value of RSSI of the bluetooth connection (S222) and determining whether or not it is less than a second threshold value (S223), and if so, determining that the anti-lost device 200 is lost (S224).
It is understood that the bluetooth modules 101 of the first and second headsets 110 and 120 are each capable of detecting the received signal strength indication received by their bluetooth, and when the first and second headsets 110 and 120 are both bluetooth connected to the anti-lost device 200, the processor 102 of the first or second headset 110 or 120 is capable of determining that the anti-lost device 200 is lost by determining a representative value of RSSI of the bluetooth connection and determining whether it is less than a first threshold value, if so.
In the case where the anti-lost device 200 maintains a bluetooth connection with only one of the first headset 110 or the second headset 120, the processor 102 of the first headset 110 or the second headset 120 can determine that the anti-lost device 200 is lost by determining a representative value of RSSI of the bluetooth connection and determining whether the representative value is less than a second threshold value, if so. It should be noted that, if the anti-lost device 200 is bluetooth-connected to only the first earphone 110, the processor 102 of the second earphone 120 can obtain the RSSI representative value of the bluetooth connection between the first earphone 110 and the anti-lost device 200, and the RSSI representative value can be transmitted from the first earphone 110 to the second earphone 120 through wireless transmission or other methods, so that the anti-lost device 200 is not bluetooth-connected to the first earphone 110, but the second earphone 120 bluetooth-connected to the first earphone 110 can also determine the loss condition of the anti-lost device 200.
In some embodiments, as shown in fig. 4 (a), the first earpiece 110 is configured to establish bluetooth communication with the anti-lost device 200, and the second earpiece 120 is configured to listen for bluetooth signals from the anti-lost device 200. It can be understood that after the first earphone 110 and the anti-lost device 200 establish the bluetooth connection, the first earphone 110 can send the communication information, such as the bluetooth address of the anti-lost device 200, the encryption parameter of the bluetooth connection between the first earphone 110 and the anti-lost device 200, to the second earphone 120 in an indirect manner or a direct manner, so that the second earphone 120 listens to and receives the audio signal sent by the anti-lost device 200. The direct mode includes a wireless mode such as bluetooth and bluetooth low energy, and the indirect mode includes a mode such as a charging box relaying communication information to the second headset 120.
Alternatively still, as shown in fig. 4 (b), the first headset 110 is configured to establish bluetooth communication with the anti-lost device 200 and forward the bluetooth signal from the anti-lost device 200 to the second headset 120.
It is understood that the first earphone 110 receives the audio information transmitted by the anti-lost device 200 and forwards the audio information to the second earphone 120, so that the second earphone 120 can also acquire the audio information transmitted by the anti-lost device 200.
In some embodiments, the bluetooth module 101 of each headset is further configured to: determining interfered related information of each frequency point of the earphone; as shown in fig. 3 (a), each headset further comprises a memory 103, the memory 103 being configured to: and storing the determined information related to the interference of each frequency point of the earphone under the condition that the earphone and the anti-lost device 200 are kept in the Bluetooth connection (S301 or S302).
The processor 102 of the first earpiece 110 or the second earpiece 120 is further configured to: when the anti-lost device 200 disconnects the bluetooth connection with the two earphones, it is determined whether the anti-lost device 200 is lost based on the interfered related information of each frequency point of the two earphones before the bluetooth connection is disconnected.
It can be understood that, due to factors affecting the bluetooth disconnection between the two earphones and the anti-lost device 200, besides the distance between the two earphones and the anti-lost device 200 is too large, there is also a case where the environmental interference where the anti-lost device 200 is located is too large, which causes the bluetooth disconnection between the anti-lost device 200 and the two earphones, for example, the anti-lost device 200 is located in a place with a great flow of people, such as a train station, an airport, and a concert, and at this time, the bluetooth disconnection between the anti-lost device 200 and the two earphones does not represent that the anti-lost device 200 is lost certainly. The memory 103 of the earphone stores the interfered information of each frequency point at a certain moment before the disconnection between the two earphones and the anti-lost device 200 or a certain time period before the disconnection, so that whether the disconnection between the anti-lost device 200 and the two earphones is caused by excessive environmental interference can be further determined, and whether the anti-lost device 200 is lost can be further determined.
In some embodiments, the interfered related information of each frequency point comprises the RSSI of the available frequency points in the frequency hopping list and/or the air interference signals of each frequency point. Determining the interfered related information of each frequency point, which can be specifically realized as follows: the number of available frequency points in the hopping list is determined (S311), and/or the RSSI of the air interference signal of each frequency point is determined (S321).
Further, as shown in fig. 3 (b), the determining whether the anti-lost device 200 is lost based on the interfered related information of each frequency point of the two headsets before the bluetooth connection is disconnected, that is, determining the number of available frequency points in the frequency hopping list (S311) and/or determining the RSSI of the air interference signal of each frequency point (S321), includes: when the number of available frequency points in the frequency hopping table is greater than a third threshold value (S312), determining that the anti-lost device 200 is lost (S313); and/or determining that the anti-lost device 200 is lost (S323) when the RSSI of the air interference signal of the frequency bin of the fourth threshold value is less than the fifth threshold value (S322).
It can be understood that, before both of the two earphones are disconnected from the anti-lost device 200 by bluetooth, the number of available frequency points in the frequency hopping list stored in the memories 103 of the two earphones exceeds the third threshold, and/or the RSSI of the air interference signal of a certain number of frequency points is smaller than the fifth threshold, which indicates that the interference suffered by the two earphones before disconnection from the anti-lost device 200 is small, and the environmental interference does not cause disconnection between the two earphones and the anti-lost device 200, so it is determined that the bluetooth disconnection is caused only because the anti-lost device 200 is lost, that is, the determination result is that the anti-lost device 200 is lost.
