Description

Technical Field

[0001] The present invention relates to the field of network connection, and in particular to a Bluetooth network connection method and system for multi-device scenarios. Background Art

[0002] The network connection between different devices can be achieved through WIFI or Bluetooth connection. When connecting different devices through WIFI, it is necessary to pre-set the WIFI network and then connect the device to the WIFI network. It is suitable for long-term continuous communication connection between devices, which puts high requirements on the security of building the WIFI network. Under normal circumstances, only temporary connection is required between different devices. When the data interaction between different devices is completed, the connection can be disconnected. At this time, it is more suitable to use Bluetooth to achieve connection between different devices. Existing Bluetooth connection methods are all implemented in a one-to-one situation, and Bluetooth connection between multiple devices cannot be achieved. When Bluetooth connection operations are performed on different devices, each device needs to be authenticated one by one, which increases the time cost of Bluetooth connection operation and the inability to quickly switch Bluetooth connection, reducing the execution efficiency and convenience of Bluetooth connection.

[0055] See also Figure 1 As shown, a Bluetooth network connection method for a multi-device scenario provided by an embodiment of the present application includes:

[0056] Perform Bluetooth detection on the surrounding environment of the service device to identify Bluetooth signal status information existing in the surrounding environment; analyze the Bluetooth signal status information to screen out all Bluetooth signals in the surrounding environment that are in a stable state;

[0057] Perform signal positioning and identification on all Bluetooth signals in a stable state, determine the user devices corresponding to all Bluetooth signals in a stable state, and obtain device attribute information corresponding to all user devices; based on the device attribute information, select a number of user devices that can simultaneously establish a Bluetooth connection with the service device from all user devices, and authenticate the selected user devices;

[0058] Based on the result of the authentication, a Bluetooth network connection is established between the service device and the corresponding user devices; based on the Bluetooth data transmission attribute information between all user devices currently connected to the network and the service device, the Bluetooth data reception status of all user devices currently connected to the network is determined.

[0059] The beneficial effects of the above embodiments are as follows: the Bluetooth network connection method for multi-device scenarios performs Bluetooth detection on the surrounding environment of the service device, obtains the Bluetooth signal status information in the surrounding environment, thereby screening the Bluetooth signals in a stable state, and determining the user devices corresponding to the Bluetooth signals in a stable state and obtaining the corresponding device attribute information, accurately determining the user devices that can be connected to the service device by Bluetooth; then authenticating the user devices, establishing a Bluetooth network connection between the service device and several user devices, and realizing Bluetooth network connection in multi-device scenarios; and also determining the Bluetooth data reception status of the service device for all user devices currently connected to the network based on the Bluetooth data transmission attribute information of all user devices currently connected to the network and the service device, thereby ensuring orderly Bluetooth data transmission between each user device and the service device, and improving the execution efficiency and convenience of the Bluetooth connection.

[0060] In another embodiment, a Bluetooth detection is performed on the surrounding environment of the service device to identify Bluetooth signal status information existing in the surrounding environment; the Bluetooth signal status information is analyzed to screen and obtain all Bluetooth signals in the surrounding environment that are in a stable state, including:

[0061] Perform Bluetooth scanning detection on the environment around the service device to identify the signal strength status information of all Bluetooth signals in the environment; analyze the signal strength status information to obtain the average signal strength value and signal strength change rate value of all identified Bluetooth signals within a preset time interval;

[0062] The average signal strength value and the signal strength change rate value are respectively compared with thresholds. If the average signal strength value is greater than or equal to a preset signal strength threshold and the signal strength change rate value is less than the preset signal strength change rate threshold, it is determined that the corresponding Bluetooth signal is in a stable state; signal names are identified for all Bluetooth signals in a stable state to form a signal name directory of all Bluetooth signals in a stable state.

[0063] The beneficial effect of the above embodiment is that there are multiple user devices in the environment where the service device is located. When the user device needs to establish a Bluetooth connection with the service device, the user device will enter the Bluetooth working mode accordingly and send out a Bluetooth signal. In this way, the Bluetooth scanning and detection of the surrounding environment of the service device is performed to identify the signal strength status information of all Bluetooth signals in the surrounding environment, so as to facilitate the quantitative analysis of the stable state of the Bluetooth signal generated by each user device. Specifically, the average signal strength value and the signal strength change rate value are respectively compared with the threshold value. If the average signal strength value is greater than or equal to the preset signal strength threshold value and the signal strength change rate value is less than the preset signal strength change rate threshold value, it indicates that the Bluetooth signal can maintain a sufficiently large signal strength and the drift of the signal strength is small. Then, the signal name of all Bluetooth signals in a stable state is identified to form a signal name directory of all Bluetooth signals in a stable state, so that the service device can establish a Bluetooth connection with the user device with a stable Bluetooth signal, improve the connection stability and continuity of the two, and avoid the occurrence of Bluetooth connection interruption.

[0064] In another embodiment, the signal strength status information is analyzed to obtain the average signal strength value and signal strength change rate value of all identified Bluetooth signals within a preset time interval, including:

[0065] Step S1, using the following formula (1), obtain the average signal strength value of all Bluetooth signals within a preset time interval:

[0066]

[0067] In the above formula (1), represents the average signal strength value of the ath Bluetooth signal identified within the preset time interval; n_a represents the total number of signal strengths of the ath Bluetooth signal collected within the preset time interval; E_a(k) represents the kth signal strength of the ath Bluetooth signal collected within the preset time interval; Indicates the minimum signal strength value of the ath Bluetooth signal collected within the preset time interval; Indicates the maximum signal strength of the ath Bluetooth signal collected within the preset time interval;

[0068] Step S2, using the following formula (2), obtain the average signal strength change rate value of all Bluetooth signals within a preset time interval,

[0069]

[0070] In the above formula (2), represents the average signal strength change rate value of the a-th Bluetooth signal identified within a preset time interval; T represents the preset time interval;

[0071] Step S3, using the following formula (3), based on the average signal strength change rate value of all Bluetooth signals identified in the preset time interval and the head and tail signal strengths, the final signal strength change rate value of all Bluetooth signals in the preset time interval is obtained,

[0072]

[0073] In the above formula (3), b_a represents the final signal strength change rate value of the a-th Bluetooth signal within a preset time interval.

[0074] The beneficial effect of the above embodiment is that the above formula (1) is used to obtain the average signal strength value of all Bluetooth signals within the preset time interval, thereby eliminating the maximum and minimum values, which can ensure that the obtained average is more convincing; then the above formula (2) is used to obtain the average signal strength change rate value of all Bluetooth signals within the preset time interval, and then the change rate of each stage is averaged to reflect the local changes within the preset time; then the above formula (3) is used to obtain the final signal strength change rate value of all Bluetooth signals within the preset time interval based on the average signal strength change rate value of all Bluetooth signals within the preset time interval and the first and last signal strengths, and then a comprehensive calculation is performed in combination with the overall change of the change rate, which can ensure the rigor of the system.

[0075] In another embodiment, signal positioning and identification are performed on all Bluetooth signals in a stable state, user devices corresponding to all Bluetooth signals in a stable state are determined, and device attribute information corresponding to all user devices is obtained; based on the device attribute information, a number of user devices that can simultaneously establish a Bluetooth connection with the service device are selected from all user devices, and the selected user devices are authenticated, including:

[0076] Perform signal position positioning and identification on all Bluetooth signals in a stable state, determine the relative position information between the user devices corresponding to all Bluetooth signals in a stable state and the service device, and obtain the device identity information corresponding to all user devices;

[0077] Based on the relative position information and device identity information of all user devices relative to the service device, all user devices located in the same position range are determined as several user devices that can simultaneously establish a Bluetooth connection with the service device; and the device identity information of the several user devices that can simultaneously establish a Bluetooth connection with the service device is compared with the device identity whitelist of the service device. If the device identity information exists in the device identity whitelist, it is determined that the authentication of the corresponding user device is successful; otherwise, it is determined that the authentication of the corresponding user device has failed.

[0078] The beneficial effects of the above embodiments include signal azimuth positioning and identification of all Bluetooth signals in a stable state, determining the relative azimuth information between the user devices corresponding to all Bluetooth signals in a stable state and the service device, thereby locating the user devices corresponding to the surrounding environment of the service device, so that all user devices in the same azimuth range are subsequently determined as several user devices that can simultaneously connect to the service device through Bluetooth, achieving synchronous Bluetooth connection between the service device and multiple user devices, and improving the efficiency of Bluetooth connection between the service device and the user devices. In addition, the device identity information of several user devices that can simultaneously connect to the service device through Bluetooth is compared with the device identity whitelist of the service device, and the user devices are securely authenticated to ensure that only successfully authenticated user devices can connect to the service device, thereby improving the Bluetooth connection security of the two.

[0079] In another embodiment, based on the result of the authentication, establishing a Bluetooth network connection between the service device and the corresponding plurality of user devices; based on the Bluetooth data transmission attribute information of all user devices currently connected to the network and the service device, determining the Bluetooth data reception status of the service device for all user devices currently connected to the network, including:

[0082] The beneficial effect of the above embodiment is that, based on the Bluetooth signal channels corresponding to all successfully authenticated user devices, the Bluetooth network connection between the service device and all successfully authenticated user devices is established, and a synchronous Bluetooth connection between the service device and multiple user devices is realized. In addition, the amount of Bluetooth data to be transmitted between all user devices currently connected to the network and the service device is obtained, and the order of receiving Bluetooth data of all user devices currently connected to the network is determined based on the order from small to large of the amount of Bluetooth data to be transmitted. This ensures that the service device can quickly and efficiently receive data from user devices. When the service device completes the reception of Bluetooth data of any user device currently connected to the network, the Bluetooth network connection between the service device and the corresponding user device is stopped, which can effectively reduce the Bluetooth connection load of the service device.

[0105] The beneficial effect of the above embodiment is that, based on the Bluetooth signal channels corresponding to all successfully authenticated user devices, the Bluetooth network connection between the service device and all successfully authenticated user devices is established, and a synchronous Bluetooth connection between the service device and multiple user devices is realized. In addition, the amount of Bluetooth data to be transmitted between all user devices currently connected to the network and the service device is obtained, and the order of receiving Bluetooth data of all user devices currently connected to the network is determined based on the order from small to large of the amount of Bluetooth data to be transmitted. This ensures that the service device can quickly and efficiently receive data from user devices. When the service device completes the reception of Bluetooth data of any user device currently connected to the network, the Bluetooth network connection between the service device and the corresponding user device is stopped, which can effectively reduce the Bluetooth connection load of the service device.

[0106] In general, the Bluetooth network connection method and system for multi-device scenarios performs Bluetooth detection on the environment around the service device to obtain Bluetooth signal status information in the surrounding environment, thereby screening Bluetooth signals in a stable state, and determining the user devices corresponding to the Bluetooth signals in a stable state and obtaining the corresponding device attribute information, accurately determining the user devices that can be connected to the service device via Bluetooth; then authenticating the user devices, establishing a Bluetooth network connection between the service device and several user devices, and realizing Bluetooth network connection in multi-device scenarios; and also determining the Bluetooth data reception status of the service device for all user devices currently connected to the network based on the Bluetooth data transmission attribute information of all user devices currently connected to the network and the service device, thereby ensuring orderly Bluetooth data transmission between each user device and the service device, and improving the execution efficiency and convenience of Bluetooth connections.

[0107] The above is only a specific implementation of the present invention, and any other improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
