[0002] The edge computing environment is usually composed of an edge cloud and edge nodes. The edge nodes can be computing nodes in the form of independent servers or edge devices with computing capabilities. Edge nodes must generally be connected to the network through wired or wireless sensor nodes. In edge computing scenarios, due to the complexity of the edge environment, edge computing nodes managed by the edge cloud usually use WiFi (Wireless Fidelity) networks to connect to the edge cloud when there is no wired network connection. Since edge nodes are in working state for a long time, it is necessary to ensure the battery life of edge nodes. However, the method of connecting to the edge cloud through a WiFi network consumes high power consumption, so the power supply needs to be frequently replaced during the continuous operation of the edge node, which greatly increases the cost of use.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In the prior art, WiFi networks are usually used to connect to edge clouds. Since edge nodes are in working state for a long time, it is necessary to ensure the endurance of edge nodes. However, the method of connecting to edge clouds via WiFi networks consumes high power. Therefore, the power supply needs to be frequently replaced during the continuous operation of edge nodes, which greatly increases the cost of use.

[0047] In order to overcome the above technical problems, the present application discloses a method, device, equipment and medium for constructing edge node network communication based on Bluetooth. Based on the low power consumption and low cost characteristics of Bluetooth communication, the edge nodes can be kept in working state for a long time, and the communication requirements of the network can be guaranteed under limited resources.

[0048] See also Figure 1 As shown, the embodiment of the present invention discloses a method for establishing a Bluetooth-based edge node network communication, which is applied to an edge node and includes:

[0049] Step S11, executing a preset Bluetooth local area network establishment script to establish a target Bluetooth local area network, and initialize the local Bluetooth to perform Bluetooth network scanning through the initialized target local Bluetooth.

[0050] In this embodiment, before establishing a Bluetooth LAN and starting Bluetooth scanning, it is necessary to first install the relevant dependent environment on the edge node, specifically, Figure 2As shown, it is necessary to update the Bluetooth environment installation list to determine the latest environment components that need to be installed in the current environment, obtain the updated Bluetooth installation list, and then determine the several environment components to be installed contained in the list according to the obtained updated Bluetooth environment installation list, such as the environment dependency components of python, python-dev, python-pip, bluetooth, bluez, pulseaudio-module-bluetooth, libsystemd-dev, and systemd in the command, and then install the above components. It is necessary to install the several environment components to be installed in the list to the local of the edge node. Furthermore, it is necessary to execute the installation check command to determine whether the above several environment components to be installed have been fully installed. If it is detected that there are target environment components to be installed that have not been successfully installed, it is necessary to reinstall the target environment components to be installed.

[0051] After the environment components are installed, it is necessary to execute the preset Bluetooth LAN establishment script to establish the target Bluetooth LAN. Specifically, since the Bluetooth network is composed of various nodes joining the Bluetooth LAN, a Bluetooth LAN server is required to provide Bluetooth services to the outside world. Therefore, in this embodiment, the bt-pan script is used as the preset Bluetooth LAN establishment script. Specifically, it is necessary to check the local network interface. After determining the local network interface, it is necessary to determine whether the local network interface is a bridge interface. If it is a bridge interface, it is necessary to determine the interface parameters of the bridge interface to determine whether there is an error in the configuration of the bridge interface based on the interface parameters. It is necessary to read the interface parameters through the preset parameter reading instruction, and determine whether the return value corresponding to the preset parameter reading instruction is empty, that is, read the standard error output of the brct1 command corresponding to the bridge interface, and check the return value of brct1.wait() and brct1_stderr If the return value is not empty, then determine the error parameters in the interface parameters and feedback the parameter error information, that is, if the brct1 command fails or has an error output, it means that there is a problem with the bridge interface configuration, and it is necessary to display the error information and the preset recommended commands to guide the user on how to correctly configure the bridge interface. In this way, the environment can be guaranteed to be complete when establishing a Bluetooth LAN.

[0052] Furthermore, if there is no error, a target Bluetooth LAN is established for the edge node, and then the local Bluetooth is initialized. Specifically, sudo bluetoothctl can be executed to enter the bluetoothctl tool, and then poweron, agent on, default-agent are executed in sequence to initialize Bluetooth, and scan on is executed to scan the surrounding Bluetooth networks.

[0053] Step S12: if the target Bluetooth local area network is scanned, join the target Bluetooth local area network, and determine whether there is a Bluetooth to be paired in the target Bluetooth local area network.

[0054] In this embodiment, if a Bluetooth LAN is scanned, it is necessary to join the target Bluetooth LAN and determine the Bluetooth to be paired in the LAN. Specifically, it is necessary to determine whether the established target Bluetooth LAN server is scanned, and join the target Bluetooth LAN after scanning the target Bluetooth LAN. You can execute trust XX:XX:XX:XX:XX:XX:XX, pairXX:XX:XX:XX:XX:XX:XX to pair with the server, where XX:XX:XX:XX:XX:XX:XX is the MAC (Media Access Control Address, LAN address) address of the server.

[0055] After joining the target Bluetooth LAN, it is necessary to loop through the device list in the target Bluetooth LAN to determine whether the device list is empty. If it is empty, it indicates that there is currently no device that can be connected. If the device list is not empty, it indicates that there is currently a Bluetooth to be paired that can be connected.

[0056] Step S13: If there is a Bluetooth to be paired, execute a preset Bluetooth connection instruction to pair with the Bluetooth to be paired, and after the pairing is successful, establish a network communication connection with a target edge node corresponding to the Bluetooth to be paired.

[0057] In this embodiment, if there is a Bluetooth to be paired in the device list, it is necessary to execute the corresponding preset Bluetooth connection instruction to pair with the Bluetooth to be paired. Specifically, ifconfig can be executed to confirm that there is an available IP (Internet Protocol). If there is an available IP, a connection is established with the available IP through the address corresponding to the available IP. If there are multiple Bluetooth nodes to be paired, they can be paired with the Bluetooth nodes to be paired in sequence according to the order of the Bluetooth nodes in the list. After the pairing is successful, a network communication connection can be established with the target edge node corresponding to the Bluetooth to be paired, and communication can be carried out through ping.

[0058] Step S14, executing a preset monitoring script to confirm in real time whether the connection with the target edge node is disconnected. If the connection is disconnected, executing a preset restart command to re-establish a network communication connection with the target edge node.

[0059] In this embodiment, since there may be a disconnection after the communication connection is established between edge nodes, it is necessary to execute a preset monitoring script, and execute a restart command to re-establish the connection after the disconnection occurs. Specifically, it is necessary to cyclically monitor whether the preset activity status monitoring interface is in an active state according to a preset cyclic monitoring interval, wherein the preset cyclic monitoring interval can be set according to the needs of the user, and in this embodiment, it is set to 20 seconds, that is, the monitoring script is executed every 20 seconds. If the preset activity status monitoring interface is not in an active state, it indicates that it is disconnected from the target edge node, and a restart command needs to be executed to re-establish a network communication connection with the target edge node.

[0060] It can be seen that the method of the present application can execute a preset Bluetooth LAN establishment script to establish a target Bluetooth LAN, then initialize Bluetooth, and perform Bluetooth network scanning through the target local Bluetooth to join the scanned target Bluetooth LAN, and if there is a Bluetooth to be paired, pair it with the Bluetooth to be paired, and after the pairing is successful, establish a network communication connection with the target edge node corresponding to the Bluetooth to be paired, and finally execute a preset monitoring script to confirm in real time whether it is disconnected from the target edge node. If it is disconnected, execute a preset restart command to re-establish a network communication connection with the target edge node. In this way, a complete implementation method of an edge node network constructed by Bluetooth technology is provided. Based on the low power consumption and low cost characteristics of Bluetooth communication, the edge node can be kept in working state for a long time, thereby avoiding the problem of frequent power supply replacement under the condition of unsustainable power supply, and ensuring the communication requirements of the network under limited resources.
