[0002] The current anti-theft technology for Bluetooth headsets stems from the continuous development of Bluetooth technology and the increasing security requirements. With the wide application of Bluetooth technology in the field of wireless communication, as an important product among them, the security issues of Bluetooth headsets have gradually attracted people's attention. However, the traditional anti-theft technology for Bluetooth headsets is realized based on the security of the Bluetooth communication protocol. This method often has some security threats and challenges. Therefore, it is necessary to introduce a brand-new anti-theft technology to improve the security of Bluetooth headsets and enhance their anti-theft ability. By performing multi-dimensional data analysis on Bluetooth headsets in the case of connection interruption, the abnormal connection state of the Bluetooth headsets can be obtained, and based on this, the Bluetooth headsets can be located, which can ensure that the Bluetooth headsets are more secure and reliable and reduce the risk of the Bluetooth headsets being stolen.

[0003] For example, the invention patent with the publication number CN113596800B is an anti-theft method for a Bluetooth charging case and a Bluetooth headset, which includes: when the Bluetooth charging case performs the first pairing and connection with a Bluetooth device, the Bluetooth charging case sends the charging case identification information to the Bluetooth device; when the Bluetooth headset performs the first pairing and connection with the Bluetooth device, the Bluetooth headset sends the headset identification information to the Bluetooth device; the Bluetooth device performs an encryption program based on its own device identification information, the charging case identification information, and the headset identification information to generate and store an identification code, and sends the identification code to the Bluetooth charging case and the Bluetooth headset that have established the first connection for storage respectively, so as to establish a binding relationship with the Bluetooth charging case and the Bluetooth headset; when the Bluetooth device and the Bluetooth headset / Bluetooth charging case that stores the identification code do not establish a connection, and it is determined that the identification code sent by the Bluetooth headset / Bluetooth charging case matches the identification code stored in itself, the Bluetooth device re-establishes a connection with the Bluetooth headset / Bluetooth charging case. Therefore, the risk of being stolen is reduced.

[0004] However, in the process of implementing the above application embodiments of the present application, it is found that the above technology has at least the following technical problems: when the Bluetooth device re-establishes a connection with the Bluetooth headset, the relevant model problems of the Bluetooth device or the Bluetooth headset are not considered, such as the accessory model of the configured device.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Referring to Figure 1 As shown, the first aspect of the present invention provides an anti-theft system for a Bluetooth headset, including: a pairing connection module, a Bluetooth headset connection anomaly evaluation module, and a Bluetooth headset anomaly positioning module.

[0029] The first aspect of the present invention provides an anti-theft system for a Bluetooth headset, further including a Bluetooth headset information database, which is used to store the defined intensity of the environmental signal, the defined effective distance of connection pairing, the defined transmission power of the Bluetooth headset signal, the defined power consumption of the Bluetooth headset, the defined intensity of the Bluetooth headset signal, the defined vibration frequency of the Bluetooth headset, the defined interruption permission duration of the Bluetooth headset, and the connection anomaly response plan corresponding to each connection anomaly degree index interval.

[0030] The pairing connection module is connected to the Bluetooth headset connection anomaly evaluation module, and the Bluetooth headset connection anomaly evaluation module is connected to the Bluetooth headset anomaly localization module. The pairing connection module, the Bluetooth headset connection anomaly evaluation module, and the Bluetooth headset anomaly localization module are all connected to the Bluetooth headset information database.

[0031] The pairing connection module is used to pair the Bluetooth headset with the configuration device, obtain connection pairing information, analyze the stable connection degree index between the Bluetooth headset and the configuration device, and thus match the monitoring system of the configuration device.

[0032] Specifically, the specific analysis process of the environmental interference influence degree coefficient is as follows:

[0033] According to the connection pairing information, environmental interference associated information and Bluetooth headset self-state associated information are extracted.

[0034] According to the environmental interference associated information, the environmental signal strength of the configuration device at each pairing time point, the effective connection pairing distance between the configuration device and the Bluetooth headset, and the configuration device adaptation model are extracted. Each pairing time point refers to dividing the set connection pairing period into each pairing time point to make the extracted data more reliable; the environmental signal strength is obtained more accurately and comprehensively by using the signal strength sensor carried by the configuration device itself to obtain the environmental signal strength data of the configuration device at each pairing time point; the effective connection pairing distance between the configuration device and the Bluetooth headset can be obtained by field testing. Starting from a short distance between the configuration device and the Bluetooth headset, gradually increase the distance between the two, and at the same time observe the connection status, and record the distance at which the connection starts to be unstable or interrupted, so as to obtain the effective connection pairing distance between the configuration device and the Bluetooth headset; the configuration device adaptation model can be directly extracted from the configuration device information warehouse, where the configuration device information warehouse is used to store configuration device parameters, configuration device status, technical information, etc.

[0035] Compare the configuration device adaptation model with the matching stability corresponding to each set adaptation model to obtain the matching stability of the configuration device, where the matching stability corresponding to each set adaptation model can be extracted from the configuration device information warehouse.

[0036] From the Bluetooth headset information database, the environmental signal definition strength and the effective connection pairing definition distance are extracted.

[0037] Comprehensively analyze the environmental interference influence degree coefficient. In a specific embodiment, the environmental interference influence degree coefficient can be obtained by selecting different test environments for benchmark testing and recording the interference data of different factors.

[0038] The above environmental interference influence degree coefficient is comprehensively analyzed in this embodiment through the environmental signal strength of the configuration device at each pairing time point, the effective connection pairing distance between the configuration device and the Bluetooth headset, and the matching stability of the configuration device, so as to determine the numerical value of the environmental interference influence degree. In this embodiment, a more accurate calculation method is used to obtain it, and the specific expression is:

[0039]

[0040] Among them, α represents the environmental interference influence degree coefficient. In this embodiment, if the environmental signal strength of the configuration device is too high at each pairing time point, it may interfere with the normal connection and communication between the configuration device and the Bluetooth headset, resulting in connection interruption or connection quality degradation, and even causing faults or damage to the circuit or components of the configuration device; an overly large effective connection pairing distance may increase the possibility of the Bluetooth headset being stolen, and for an overly large effective connection pairing distance, the signal stability may be affected. In order to maintain a long-distance connection, the Bluetooth headset may need to consume more power; when the matching stability of the configuration device is too low, incompatibility problems are likely to occur, resulting in system crashes and lags of the configuration device, which not only affect the user experience but also pose a threat to data security transmission. To sum up, parameters such as the environmental signal strength at each pairing time point, the effective connection pairing distance between the configuration device and the Bluetooth headset, and the matching stability of the configuration device all have important influences on the environmental interference influence degree coefficient. When calculating the environmental interference influence degree coefficient, the negative impacts brought by these factors should be fully considered to reduce the influence of environmental interference.

[0041] S i represents the environmental signal strength of the configuration device at the i-th pairing time point, which refers to the strength of the environmental signal at a certain pairing time point. The environmental signal strength is affected by various factors, such as signal sources, environmental obstacles, and weather conditions.

[0042] i is the number of each pairing time point, i = 1, 2, 3,..., m, and m is the number of pairing time points.

[0043] S' represents the environmental signal defined strength, which refers to the maximum strength allowed for the environmental signal.

[0044] CO represents the effective connection pairing distance between the configuration device and the Bluetooth headset, which refers to the maximum distance at which the configuration device and the Bluetooth headset can communicate with each other under the premise of maintaining a stable connection state. This distance is affected by various factors, including Bluetooth headset version, configuration device type, signal strength, obstacles, and electromagnetic interference, etc.

[0045] CO' is expressed as the effective defined distance for connection pairing, which refers to the maximum distance permitted when discussing the effective distance for connection pairing.

[0046] EQ is expressed as the matching stability of the configured device, which refers to the degree to which the model of the configured device conforms to the required model of the configured device. Good matching stability of the configured device can reduce connection failures or instability caused by model problems.

[0047] b1 is expressed as the correction factor corresponding to the predefined environmental signal strength, b2 is expressed as the correction factor corresponding to the predefined effective distance for connection pairing, b3 is expressed as the influencing factor corresponding to the unit value of the predefined matching stability, and e is the natural constant.

[0048] Furthermore, the coefficient of the influence of the state of the Bluetooth headset itself, the specific analysis process is as follows:

[0049] According to the correlation information of the state of the Bluetooth headset itself, the signal transmission power of the Bluetooth headset at each pairing time point, the power consumption of the Bluetooth headset within the set connection pairing period, and the adapted model of the Bluetooth headset are extracted. Among them, the signal transmission power at each pairing time point can be measured in real time by the power sensor carried by the Bluetooth headset to obtain the value of the signal transmission power at each pairing time point; the power consumption of the Bluetooth headset within the set connection pairing period can be obtained by real-time recording. Record the current power of the Bluetooth headset at the start time point of the set connection pairing period, record the current power of the Bluetooth headset at the end time point of the set connection pairing period, and through difference processing, obtain the power consumption of the Bluetooth headset within the set connection pairing period; directly extract the adapted model of the Bluetooth headset from the Bluetooth headset information library.

[0050] Compare the adapted model of the Bluetooth headset with the connection stability corresponding to each set adapted model to obtain the connection stability of the Bluetooth headset, where the connection stability corresponding to each set adapted model can be directly extracted from the Bluetooth headset information library.

[0051] From the Bluetooth headset information library, the signal transmission defined power and the defined power consumption of the Bluetooth headset are extracted.

[0052] Comprehensively analyze the coefficient of the influence of the state of the Bluetooth headset itself. In a specific embodiment, the state information of the Bluetooth headset itself can be obtained through big data collection technology, including the usage log, sensor data, user feedback, repair record, etc. of the Bluetooth headset. Based on these data, a mathematical model is constructed to evaluate the various performances of the Bluetooth headset, so as to obtain the coefficient of the influence of the state of the Bluetooth headset itself.

[0053] The coefficient of the influence of the above Bluetooth headset's own state is, in this embodiment, obtained through comprehensive analysis of the signal transmission power of the Bluetooth headset at each pairing time point, the power consumption of the Bluetooth headset within a set connection pairing period, and the connection stability of the Bluetooth headset, so as to determine the value of the influence degree of the Bluetooth headset's own state. In this embodiment, a more accurate calculation method is used to obtain it, and the specific expression is:

[0054]

[0055] Among them, β represents the coefficient of the influence of the Bluetooth headset's own state. In this embodiment, a relatively high signal transmission power of the Bluetooth headset usually means that the Bluetooth headset has stronger signal transmission ability and a longer connection distance, but at the same time, it may also lead to higher power consumption; the amount of power consumption is directly affected by various factors such as signal transmission power, usage time, and usage mode. A relatively high signal transmission power will increase the power consumption of the headset, thereby shortening its usage time; a relatively low connection stability of the Bluetooth headset will directly affect the data transmission quality and security of the Bluetooth headset signal. Improving the connection stability of the Bluetooth headset can effectively reduce the situation of signal interruption and connection failure; in summary, the signal transmission power, the power consumption of the Bluetooth headset, and the connection stability are all important factors affecting the coefficient of the influence of the Bluetooth headset's own state. When using the Bluetooth headset, these factors need to be comprehensively considered to achieve the best performance and user experience.

[0056] PO i represents the signal transmission power of the Bluetooth headset at the i-th pairing time point, which refers to the power used by the Bluetooth headset when sending signals and is an important parameter to measure the transmission ability of the Bluetooth headset. It directly affects the coverage range and quality of the Bluetooth headset communication.

[0057] i is the number of each pairing time point, i = 1, 2, 3,..., m, and m is the number of pairing time points.

[0058] PO' represents the defined signal transmission power of the Bluetooth headset, which refers to the minimum allowable signal transmission power of the Bluetooth headset.

[0059] EL represents the power consumption of the Bluetooth headset within a set connection pairing period, which refers to the electrical energy consumed by the Bluetooth headset to establish and maintain a connection relationship with the paired device within this period. This period may include various stages such as searching, pairing, connecting, data transmission, and standby of the Bluetooth headset.

[0060] EL' represents the defined power consumption of the Bluetooth headset, which refers to the maximum allowable power consumption of the Bluetooth headset.

[0061] MO represents the connection stability of the Bluetooth headset, which refers to the connection quality of the Bluetooth signal between the Bluetooth headset and the configured device, as well as whether problems such as disconnection and noise are likely to occur during use.

[0062] b4 represents the correction factor corresponding to the predefined Bluetooth headset signal transmission power, b5 represents the correction factor corresponding to the predefined power consumption of the Bluetooth headset, b6 represents the influence factor corresponding to the unit value of the predefined connection stability, and e is the natural constant.

[0063] Specifically, the monitoring system that matches the configured device can, in a specific embodiment, conduct actual use tests in different environments, including indoor, outdoor, mobile, etc. scenarios, to observe the stable connection degree between the Bluetooth headset and the configured device, so as to obtain the stable connection degree index between the Bluetooth headset and the configured device.

[0064] In this embodiment, the stable connection degree index between the above-mentioned Bluetooth headset and the configured device is obtained through comprehensive analysis of the environmental interference influence degree coefficient and the Bluetooth headset's own state influence degree coefficient, and is used to determine the value of the stable connection degree between the Bluetooth headset and the configured device. This embodiment uses a more accurate calculation method, and the specific process is as follows:

[0065]

[0066] Among them, γ represents the stable connection degree index between the Bluetooth headset and the configured device. In this embodiment, when the environmental interference influence degree coefficient is high, that is, there are many interference sources in the environment, the connection stability of the Bluetooth headset may be seriously affected, resulting in a corresponding decrease in the stable connection degree index between the Bluetooth headset and the configured device; if the Bluetooth headset's own state is not good, such as the Bluetooth module is aging, the antenna reception ability is weak, the battery power is low, or the software has defects, then its connection stability may also be affected, which will also lead to a decrease in the stable connection degree index between the Bluetooth headset and the configured device; therefore, when evaluating the stable connection degree index between the Bluetooth headset and the configured device, it is necessary to comprehensively consider the environmental interference influence degree coefficient and the Bluetooth headset's own state influence degree coefficient, so as to improve the stable connection degree index between the Bluetooth headset and the configured device, thereby ensuring a better user experience.

[0067] α represents the environmental interference influence degree coefficient, which is obtained through comprehensive analysis of the environmental signal strength of the configured device at each pairing time point, the effective connection pairing distance between the configured device and the Bluetooth headset, and the matching stability of the configured device.

[0068] β is expressed as the coefficient of the influence degree of the Bluetooth headset's own state, which is obtained by comprehensively analyzing the signal transmission power of the Bluetooth headset at each pairing time point, the power consumption of the Bluetooth headset within the set connection pairing period, and the connection stability of the Bluetooth headset.

[0069] d1 is expressed as the weight factor corresponding to the pre-defined influence degree coefficient of environmental interference, d2 is expressed as the weight factor corresponding to the pre-defined influence degree coefficient of the Bluetooth headset's own state, and e is the natural constant.

[0070] Match the stable connection degree index between the Bluetooth headset and the configured device with the monitoring states corresponding to each set stable connection degree index to obtain the monitoring state of the configured device, and thus extract the monitoring system of the configured device. The above monitoring state of the configured device changes in real time according to the operation of the configured device.

[0071] The Bluetooth headset connection anomaly evaluation module is used to extract the Bluetooth headset connection interruption monitoring system of the configured device through the monitoring system of the configured device. The monitoring system of the configured device includes multiple sets of monitoring system data such as the Bluetooth headset connection interruption monitoring system and the operation system of the configured device itself; obtain the connection interruption correlation information of the Bluetooth headset and evaluate the connection anomaly degree index of the Bluetooth headset.

[0072] Specifically, the analysis process of the influence degree coefficient of the Bluetooth headset's position state is as follows:

[0073] Extract the Bluetooth headset position state correlation information and the Bluetooth headset usage state correlation information according to the connection interruption correlation information of the Bluetooth headset.

[0074] Extract the interruption position influence degree, signal strength, and vibration frequency of the Bluetooth headset at the connection interruption start time point according to the Bluetooth headset position state correlation information. The interruption position influence degree of the Bluetooth headset at the connection interruption start time point can be obtained by extracting the specific position of the Bluetooth headset at the connection interruption start time point through the Bluetooth headset connection interruption monitoring system of the configured device, and thus matching the interruption position influence degree of the Bluetooth headset; the signal strength and vibration frequency at the connection interruption start time point can be obtained through the signal strength sensor and vibration frequency sensor carried by the Bluetooth headset itself, respectively.

[0075] Extract the Bluetooth headset signal defined strength and the Bluetooth headset vibration defined frequency from the Bluetooth headset information library.

[0076] Comprehensively analyzing the influence degree coefficient of the position state of the Bluetooth headset, in a specific embodiment, the method of simulation can be used. By using computer simulation software, a signal transmission model between the Bluetooth headset and the configured device is constructed to simulate the performance of the Bluetooth headset in different position states. Through the simulation results, the influence degree of the position state on the performance of the Bluetooth headset is analyzed, so as to obtain the influence degree coefficient of the position state of the Bluetooth headset.

[0077] The above-mentioned influence degree coefficient of the position state of the Bluetooth headset, in this embodiment, is obtained through comprehensive analysis of the interruption position influence degree, signal strength, and vibration frequency at the starting time point of connection interruption, and is used to determine the numerical value of the influence degree of the position state of the Bluetooth headset. In this embodiment, a more accurate calculation method is adopted, and the specific expression is:

[0078]

[0079] Among them, δ represents the influence degree coefficient of the position state of the Bluetooth headset. In this embodiment, when the interruption position influence degree is high, it indicates that the Bluetooth headset is prone to connection interruption in a certain position or environment, which directly affects the use stability and user experience of the Bluetooth headset; the strength of the signal directly affects the connection stability and data transmission speed of the Bluetooth headset. When the signal strength is weak, the connection is easily interfered and interrupted, especially when the distance between the Bluetooth headset and the configured device is far or there are obstacles blocking, which has a negative impact on finding the Bluetooth headset; a higher vibration frequency can provide a fast and intuitive way to find the headset when the user is close to the Bluetooth headset. When the vibration is too weak or the frequency is inappropriate, the user may not be able to perceive it, thus reducing the effect of retrieving the headset; comprehensively considering the three factors of interruption position influence degree, signal strength, and vibration frequency can more comprehensively evaluate the influence degree coefficient of the position state of the Bluetooth headset, which helps users quickly and accurately find the stolen Bluetooth headset, improve the success rate of retrieving the headset, and reduce the risk of the Bluetooth headset being stolen.

[0080] XY represents the interruption position influence degree of the Bluetooth headset at the starting time point of connection interruption, which refers to the influence degree on the user's use experience caused by the occurrence of the connection interruption between the Bluetooth headset and the configured device at the starting time point of connection interruption. The interruption position influence degree is a measure of the frequency and severity of the connection interruption of the Bluetooth headset in different positions.

[0081] Sr represents the signal strength of the Bluetooth headset at the starting time point of connection interruption, which refers to the strength of the wireless signal transmission between the Bluetooth headset and the configured device at the starting time point of connection interruption. The stronger the signal strength, the more stable the connection and the smaller the possibility of interruption.

[0082] Sr' represents the defined signal strength of the Bluetooth headset, which refers to the minimum strength specified for the Bluetooth headset signal.

[0083] Fr represents the vibration frequency of the Bluetooth headset at the starting time point of connection interruption, which refers to the frequency generated by its own vibration at the starting time point of connection interruption. When the connection is interrupted, the Bluetooth headset will remind the user with a specific vibration frequency.

[0084] Fr' represents the defined vibration frequency of the Bluetooth headset, which refers to the minimum frequency permitted for the Bluetooth headset vibration.

[0085] a1 represents the influence factor corresponding to the unit value of the predefined interruption position influence degree, a2 represents the correction factor corresponding to the predefined Bluetooth headset signal strength, a3 represents the correction factor corresponding to the predefined Bluetooth headset vibration frequency, and e is the natural constant.

[0086] Furthermore, the analysis process of the influence degree coefficient of the Bluetooth headset usage state is as follows:

[0087] According to the Bluetooth headset usage state associated information, the interruption duration of the Bluetooth headset and the number of indicator light flashes of the Bluetooth headset within the set connection interruption cycle are extracted. The interruption duration of the Bluetooth headset can be directly extracted from the Bluetooth headset connection interruption monitoring system of the configuration device; the number of indicator light flashes of the Bluetooth headset within the set connection interruption cycle can be counted by the Bluetooth headset connection interruption monitoring system of the configuration device to obtain the number of indicator light flashes of the Bluetooth headset within the set connection interruption cycle.

[0088] The permitted interruption duration of the Bluetooth headset is extracted from the Bluetooth headset information library.

[0089] Based on this, the influence degree coefficient of the Bluetooth headset usage state is analyzed. In a specific embodiment, it can be obtained by collecting a large amount of user feedback data on the Bluetooth headset usage state, including satisfaction scores, usage habits, problems encountered, etc., and then using cloud computing methods to quantitatively process the user feedback data.

[0090] The above-mentioned influence degree coefficient of the Bluetooth headset usage state is obtained through comprehensive analysis of the interruption duration of the Bluetooth headset and the number of indicator light flashes of the Bluetooth headset within the set connection interruption cycle in this embodiment, and is used to determine the value of the influence degree of the Bluetooth headset usage state. In this embodiment, a more accurate calculation method is adopted, and the specific expression is:

[0091]

[0092] Among them, μ represents the coefficient of the impact on the usage status of the Bluetooth headset. In this embodiment, the longer the interruption duration of the Bluetooth headset, the worse the user's connection experience, the greater the possibility of the headset being stolen, and the smaller the possibility of finding it, resulting in a significant decline in the user experience quality, thus having a negative impact on the usage status of the Bluetooth headset. During the set connection interruption period, if the number of times the indicator light flashes is too small, it is not conducive to prompting the user about the status information of the Bluetooth headset, resulting in the user being unable to detect the abnormal changes of the Bluetooth headset in time and affecting the normal use of the Bluetooth headset. To sum up, both the interruption duration of the Bluetooth headset and the number of times the indicator light flashes are important factors for evaluating the coefficient of the impact on the usage status of the Bluetooth headset. When designing and optimizing the anti-theft technology of the Bluetooth headset, attention should be paid to the performance of these indicators, and effective measures should be taken to improve the connection stability and user experience of the Bluetooth headset.

[0093] T represents the interruption duration of the Bluetooth headset, which refers to the duration when the connection between the Bluetooth headset and the configured device is interrupted. When the Bluetooth headset loses connection with the paired device due to signal loss, out-of-range, device failure, or other reasons, the interruption duration starts to be calculated.

[0094] T' represents the permitted interruption duration of the Bluetooth headset, which refers to the maximum duration allowed when discussing the interruption duration of the Bluetooth headset.

[0095] ST represents the number of times the indicator light of the Bluetooth headset flashes within the set connection interruption period, which refers to the number of times the indicator light of the Bluetooth headset flashes due to connection interruption within this set period. By recording and analyzing the number of flashes within this period, the prompting effect and user perception of the Bluetooth headset during connection interruption can be understood.

[0096] f1 represents the correction factor corresponding to the predefined interruption duration of the Bluetooth headset, f2 represents the impact factor corresponding to a single indicator light flash, and e is the natural constant.

[0097] Specifically, in a specific embodiment, the connection anomaly degree index of the Bluetooth headset can be obtained through the log analysis of the configured device. When the Bluetooth headset is connected to the configured device, the configured device will record the connection logs. By analyzing these logs, the abnormal situations during the connection process, such as disconnection and signal strength fluctuations, can be understood. These logs usually contain detailed connection data, and thus the connection anomaly degree index of the Bluetooth headset can be obtained.

[0098] In this embodiment, the above-mentioned connection anomaly degree index of the Bluetooth headset is obtained through the comprehensive analysis of the stable connection degree index between the Bluetooth headset and the configured device, the impact degree coefficient of the Bluetooth headset position status, and the impact degree coefficient of the Bluetooth headset usage status, and is used to determine the numerical value of the connection anomaly degree of the Bluetooth headset. In this embodiment, a more accurate calculation method is adopted, and the specific expression is:

[0099]

[0100] Where θ represents the connection anomaly degree index of the Bluetooth headset. In this embodiment, when the stable connection degree between the Bluetooth headset and the configured device is smaller, the connection anomaly of the Bluetooth headset is more obvious. At this time, the connection anomaly does not belong to the stolen connection anomaly; the distance between the position of the Bluetooth headset and the configured device directly affects the signal strength. The farther the distance, the more serious the signal attenuation, which may lead to unstable connection or disconnection; the battery level of the Bluetooth headset directly affects its working performance and stability. Low battery may lead to unstable connection or degraded signal quality, thus affecting the connection anomaly degree index. To sum up, both the influence degree coefficient of the Bluetooth headset position state and the influence degree coefficient of the usage state will affect the connection anomaly degree index of the Bluetooth headset in different ways, and the stable connection degree index between the Bluetooth headset and the configured device will also affect the connection anomaly degree index of the Bluetooth headset. When evaluating the connection performance of the Bluetooth headset, these factors need to be considered comprehensively to more accurately understand the cause and degree of the connection anomaly, so as to take corresponding measures to optimize the connection stability.

[0101] γ represents the stable connection degree index between the Bluetooth headset and the configured device, which is obtained by comprehensively analyzing the influence degree coefficient of environmental interference and the influence degree coefficient of the Bluetooth headset's own state.

[0102] δ represents the influence degree coefficient of the Bluetooth headset position state, which is obtained by comprehensively analyzing the interruption position influence degree, signal strength, and vibration frequency of the Bluetooth headset at the starting time point of connection interruption.

[0103] μ represents the influence degree coefficient of the Bluetooth headset usage state, which is obtained by comprehensively analyzing the interruption duration of the Bluetooth headset and the number of indicator light flashes of the Bluetooth headset within the set connection interruption period.

[0104] g1 represents the weight factor corresponding to the predefined stable connection degree index, g2 represents the weight factor corresponding to the predefined influence degree coefficient of the Bluetooth headset position state, g3 represents the weight factor corresponding to the predefined influence degree coefficient of the Bluetooth headset usage state, and e is the natural constant.

[0105] The Bluetooth headset anomaly positioning module is used to match and obtain the Bluetooth headset connection anomaly response plan according to the connection anomaly degree index of the Bluetooth headset, thereby positioning the anomaly position point of the Bluetooth headset.

[0106] Specifically, the process of positioning the anomaly position point of the Bluetooth headset is as follows:

[0107] Match the connection anomaly degree index of the Bluetooth headset with the connection anomaly response plans corresponding to each connection anomaly degree index interval defined in the Bluetooth headset information library to obtain the connection anomaly response plan for the Bluetooth headset. The connection anomaly response plans corresponding to each connection anomaly degree index interval refer to taking corresponding measures to solve or alleviate the connection problem according to the preset minor anomaly response plan, moderate anomaly response plan, and severe anomaly response plan when it is monitored that the connection anomaly degree index of the Bluetooth headset is in different numerical ranges.

[0108] Through the connection anomaly response plan of the Bluetooth headset, extract the initial position point of the connection anomaly of the Bluetooth headset and the abnormal action trajectory, and obtain the abnormal position point of the Bluetooth headset through numerical processing and analysis. The above abnormal position point of the Bluetooth headset uses machine learning and statistical learning algorithms to model and analyze the collected initial position points of the connection anomaly and abnormal action trajectory data, identify normal and abnormal patterns through training models, and then predict and locate the abnormal position point.

[0109] Refer to Figure 2 As shown, the second aspect of the present invention provides a theft prevention method for a Bluetooth headset, including: pairing the Bluetooth headset with a configuration device and obtaining connection pairing information, analyzing the stable connection degree index between the Bluetooth headset and the configuration device, and thus matching to obtain the monitoring system of the configuration device; through the monitoring system of the configuration device, extract the Bluetooth headset connection interruption monitoring system of the configuration device, obtain the connection interruption correlation information of the Bluetooth headset, and evaluate the connection anomaly degree index of the Bluetooth headset; according to the connection anomaly degree index of the Bluetooth headset, match to obtain the connection anomaly response plan of the Bluetooth headset, and thus locate the abnormal position point of the Bluetooth headset.

[0110] The third aspect of the present invention provides a theft prevention Bluetooth headset, including: a Bluetooth headset and a configuration device; the Bluetooth headset and the configuration device are connected through Bluetooth technology, where Bluetooth technology provides a wireless access to the Internet for the configuration device, enabling the configuration device to directly perform data transmission and Internet communication with the Bluetooth headset without the need for a wired cable. In addition, when the configuration device performs Internet communication with the Bluetooth headset, certain rules and agreements, that is, protocols, need to be followed. Common protocols include TCP / IP protocol, HTTP protocol, FTP protocol, etc.

[0111] And anti-theft of the Bluetooth headset is carried out through the Bluetooth distance reminder function; a device signal strength sensor is configured to obtain the environmental signal strength of the configured device at each pairing time point; a Bluetooth headset power sensor is used to collect the signal transmission power of the Bluetooth headset at each pairing time point; a Bluetooth headset signal strength sensor is used to obtain the signal strength of the Bluetooth headset at the starting time point of connection interruption; a Bluetooth headset vibration frequency sensor is used to obtain the vibration frequency of the Bluetooth headset at the starting time point of connection interruption; a processor is used to obtain the environmental signal strength, signal transmission power, signal strength and vibration frequency and analyze and process them, and then locate the abnormal position points of the Bluetooth headset.
