[0002] When IoT devices are currently networking, users usually need to manually configure them, such as connecting devices to the network via Bluetooth or WiFi. This method is not only cumbersome to operate, but also makes it more difficult to connect devices to the network in some industrial scenarios because it is impossible to carry configuration tools such as computers.

[0003] In the prior art, devices are manually configured to access the network and rely on fixed network addresses for communication. However, the manual configuration process is cumbersome and increases the user threshold. Fixed network addresses may cause network congestion and address conflicts. Therefore, there is room for improvement. Summary of the invention

[0006] By adopting the above technical solution, since the server of the Openthread gateway built on a single node is prone to network connection failure when processing multi-device connection access, affecting the user's access to the network, the network connection access request of the device to be connected is received by the Openthread gateway, and the network connection access request is inspected through a preset inspection mechanism to determine whether the device to be connected is an industrial device or a smart furniture device, and the connection node load value between the device to be connected that meets the inspection mechanism and all Openthread gateway servers is calculated, so as to obtain the transmission pressure when accessing the connection node through the Openthread gateway server, and then dynamically adjust the node number transmission flow of the Openthread gateway server, and the Openthread gateway is inspected according to the connection node load value. The server is weighted polled, and the performance of all Openthread gateway servers is evaluated according to the polling results. According to the performance evaluation results, the best Openthread gateway server is selected to transmit data to the connected device. According to the network connection requirements of the device to be connected, the Openthread gateway server with the best performance evaluation result is dynamically selected to adjust the network connection of the device to be connected, so that the Openthread gateway server is always kept in the best connection state, reducing the impact of load failure on the Openthread gateway server caused by the access pressure of multiple devices. According to the actual network connection requirements of the device to be connected, the number of nodes of the Openthread gateway is dynamically adjusted, and the transmission flow is realized, thereby realizing automatic scanning and automatic addressing, and simplifying the on-site network configuration process.

When a network connection access request is received, the device unique identification code is obtained through the corresponding authentication field identification, and the device unique identification code is input into the server of the Openthread gateway for comparison with the authentication identification code. According to the comparison result of the identification code, it is determined whether the device to be connected is still in the list of devices to be connected in the system, and then the access permission data of the device to be connected to the intranet is obtained, so as to process the network connection access request with the same comparison result, that is, the device to be connected belongs to the access permission range of the list of devices to be connected in the system, and build a node data transmission link between the device to be connected and the server of the Openthread gateway with the best performance evaluation result through the Openthread gateway, thereby improving the convenience of device access to the network, reducing the probability of devices that do not belong to the system accessing the network, and improving the network security of the server of the Openthread gateway.

[0010] By adopting the above technical scheme, according to the processing of the network connection access request by the server of the Openthread gateway, the node data transmission bandwidth value of the server of the Openthread gateway that the device to be connected needs to occupy is obtained, and according to the preset load sharing rule of the Openthread gateway, the access processing time of the server of the Openthread gateway for the node data transmission bandwidth value of the device to be connected is calculated, which helps to quickly select the server of the Openthread gateway with the best network connection performance according to the access processing time, and call the Openthread gateway to connect the server of the Openthread gateway with the best access processing time, that is, the server of the Openthread gateway with the best performance evaluation result to the device to be connected, so as to dynamically select the best Openthread gateway server for connection according to the actual node bandwidth of the network connection of the device to be connected, so as to achieve the effect of dynamic diversion according to the actual network access demand of the device to be connected, and improve the adaptability between the server of the Openthread gateway and the actual bandwidth demand of the device to be connected.

[0011] In a preferred example, the present application can be further configured as follows: after obtaining the network connection access request sent by the to-be-linked device to the Openthread gateway in real time, and before checking the network connection access request through the inspection mechanism preset by the server of the Openthread gateway, and calculating the connection node load value between the to-be-linked device that meets the inspection mechanism and the servers of all Openthread gateways according to the inspection result, it also includes: Each IP address of the server of the Openthread gateway is routed to each network segment to obtain an initialized IP address pool connected to the intranet; Get the routing time of each IP address and each network segment in the initialized IP address pool; According to the routing time, a flow control policy is matched for each IP address to obtain a flow control policy that conforms to the initialized IP address pool; A flow control strategy matching process is performed on the device to be linked, and the node number transmission flow of the device to be linked is adjusted according to the matching result to obtain the node number transmission flow with the best matching degree with the device to be linked.

[0012] By adopting the above technical solution, before calculating the connection node load value of the device to be linked, the server of the Openthread gateway is initialized first, and each IP address of the server of the Openthread gateway is routed and connected to each network segment according to the size of the authority, and whether the node data transmission link between each IP address and the corresponding network segment is normal is judged according to the routing connection result, so as to obtain an initialized IP address pool connected to the network, which is helpful to verify the access status between the server of the Openthread gateway and the network in real time, and reduce the impact of network access error caused by the disconnection of the access link, and judge the actual flow demand of each IP address to obtain feedback data according to the routing time between each IP address and the corresponding network segment, and match the flow control strategy for each IP address in a targeted manner, so as to obtain a flow control strategy that conforms to the initialized IP address pool, and after receiving the network connection access request of the device to be linked, the initialized flow control strategy is matched with the device to be linked according to the IP address of the device to be linked, and the node number transmission flow of the device to be linked is accurately adjusted through the flow control strategy, so as to achieve the purpose of accurately regulating the node number transmission flow of the server of the Openthread gateway, and improve the accuracy of the node number transmission flow distribution of the server of the Openthread gateway.

[0013] In a preferred example, the present application can be further configured as follows: according to the performance evaluation result, the device to be linked is linked to the server of the Openthread gateway with the best performance evaluation result, so as to facilitate multi-node shunting transmission to the server of the Openthread gateway, specifically including: According to the performance evaluation result, the server of the Openthread gateway with the best adaptability to the device to be connected is selected as the server of the main Openthread gateway; Linking the device to be linked to the server of the main Openthread gateway, and processing the network connection access request of the device to be linked; According to the network connection access request, searching for a target network segment that is compatible with the device to be connected, and receiving feedback data of the target network segment; According to the preset node data transmission rules of the Openthread gateway, the feedback data is synchronously pushed to the server of the subordinate Openthread gateway which is secondary to the server of the main Openthread gateway.

[0014] By adopting the above technical scheme, according to the performance evaluation results of all Openthread gateway servers, the Openthread gateway selects the server of the Openthread gateway with the best adaptability to the device to be connected as the server of the main Openthread gateway, which is helpful to select the most suitable Openthread gateway server according to the actual node data transmission requirements, and reduce the operating pressure of the single-node Openthread gateway server to handle the network connection access data of multiple devices at the same time. The Openthread gateway builds a link channel between the device to be connected and the server of the main Openthread gateway, and calls the server of the main Openthread gateway to process the network connection access request of the device to be connected. The server of the main Openthread gateway searches for the target network segment that is compatible with the device to be connected, which helps to reduce the unauthorized network access of the device to be connected and improve the security of network access. According to the preset Openthread gateway data transmission rules, when the Openthread gateway sends the received feedback data to the server of the main Openthread gateway, the feedback data is synchronously pushed to the server of the subordinate Openthread gateway that is secondary to the server of the main Openthread gateway, which helps to reduce the network connection data asynchronism caused by the single point failure of the server of the main Openthread gateway, thereby improving the node data transmission stability of the server of the Openthread gateway.

[0016] By adopting the above technical solution, the node data transmission status between the device to be linked and the server of the main Openthread gateway is monitored in real time through the heartbeat detection of the Openthread gateway. When the node data transmission status fails, the Openthread gateway is called to recalculate the authority values ​​of all the slave Openthread gateway servers, and the slave Openthread gateway server with the best authority value is selected as the server of the main Openthread gateway to take over the network access work of the failed main Openthread gateway server, thereby reducing the network access delay caused by the server failure of the main Openthread gateway, and according to the unique IP address of the device to be linked, the Openthread gateway is used to build the connection between the device to be linked and the server of the main Openthread gateway in the slave Openthread gateway server.

[0032] The following is combined with Figure 1-8 This application is described in further detail.

[0033] In one embodiment, if Figure 1 As shown, the present application discloses a method for proximity networking and automatic addressing based on Openthread, which specifically includes the following steps: S10: Obtain the network connection access request sent by the device to be connected to the Openthread gateway in real time.

[0034] Specifically, when the device to be linked needs network access to access the server of the Openthread gateway, the server of the Openthread gateway automatically obtains the information of the device to be linked and generates a network connection access request and sends it to the Openthread gateway for data verification. Through the login access of the device to be linked to the Openthread gateway, a node data transmission channel is established between the device to be linked and the Openthread gateway, and the network connection access request sent by the device to be linked to the Openthread gateway is obtained through the node data transmission channel, wherein the network connection access request carries the device information of the device to be linked.

[0035] In one embodiment, in order to better accurately control the flow of each IP address, such as Figure 2 As shown, after obtaining the network connection access request sent by the device to be connected to the Openthread gateway in real time, and before checking the network connection access request through a preset inspection mechanism, and calculating the connection node load value between the device to be connected that meets the inspection mechanism and the servers of all Openthread gateways according to the inspection result, it also includes: S101: Each IP address of the server of the Openthread gateway is routed to each network segment to obtain an initialized IP address pool connected to the intranet.

[0036] Specifically, according to the network access access rights of each IP address of the server of the Openthread gateway, each IP address in the server of the Openthread gateway is routed to each network segment respectively, which helps to pre-check the network access access rights of each IP address and the feasibility of network access, so as to obtain an initialized IP address pool that is interconnected with the corresponding network segment according to the routing results.

[0037] S102: Obtain the routing time of each IP address and each network segment in the initialized IP address pool.

[0038] Specifically, during the routing connection process between each IP address and the corresponding network segment, the timing starts when the IP address starts to attempt routing, and ends when the feedback signal of successful network segment routing is obtained. The time from the start of routing to the end of successful routing is counted to obtain the routing time between each IP address and each network segment. The routing time helps to reasonably allocate the number of nodes required for IP address routing to transmit traffic.

[0039] S103: Matching a flow control policy for each IP address according to the routing time to obtain a flow control policy that complies with the initialized IP address pool.

[0040] Specifically, according to the routing time of each IP address to the intranet, the traffic control strategy is matched for each IP address respectively, wherein the traffic control strategy is pre-trained by several historical node transmission traffic and the corresponding routing time, and stored in the Openthread gateway. According to the traffic control strategy matching result, the traffic control strategy is associated with the corresponding initialization IP address pool respectively to obtain the traffic control strategy that conforms to the initialization IP address pool. In the routing time of the constantly updated IP address pool, the pre-stored traffic control strategy can be further optimized and updated to make the traffic control strategy more in line with the actual traffic transmission needs of the server of the Openthread gateway.

[0041] S104: Perform flow control strategy matching processing on the device to be linked, and adjust the node number transmission flow of the device to be linked according to the matching result to obtain the node number transmission flow with the best matching degree with the device to be linked.

[0042] Specifically, the IP address of the device to be connected is compared with the IP address in the initialized IP address pool, and the corresponding flow control strategy is matched to the device to be connected according to the comparison result, so that the corresponding node number transmission flow is called according to the corresponding flow control strategy to perform data transmission on the device to be connected, thereby obtaining the node number transmission flow that best matches the device to be connected, and achieving the purpose of reasonably regulating the node number transmission flow of the device to be connected.

[0043] S20: The network connection access request is inspected through a preset inspection mechanism, and based on the inspection result, the connection node load value between the device to be connected that meets the inspection mechanism and the servers of all Openthread gateways is calculated.

[0044] Specifically, Figure 3 As shown, step S20 includes: S201: receiving in real time the inventory data of the devices to be connected in the system, and performing encryption calculation on the inventory data of the devices to be connected in the system to obtain an authentication identification code that complies with the device verification mechanism.

[0045] Specifically, the inventory data of the devices to be connected in the industrial equipment system or the smart furniture system is pulled into the database, the inventory data of the devices to be connected is generated, and the inventory data of the devices to be connected is calculated according to the encryption algorithm to obtain an authentication identification code that complies with the user verification mechanism of the database. The calculation parameters can be the name, number, model, etc. of the device, which can be set according to actual needs. The authentication identification code is unique in the inventory data of the same device to be connected.

[0046] S202: Obtain the device unique identification code carried in the network connection access request.

[0047] Specifically, based on the network connection access request received by the Openthread gateway, specific authentication fields in the network connection access request, such as the device name, number, model, etc., are identified, and then the specific authentication fields are calculated through a preset encryption algorithm to obtain a unique device identification code, thereby reducing the traditional certificate authorization login steps.

[0048] S203: Input the unique identification code of the device into the server of the Openthread gateway for comparison with the authentication identification code to obtain the identification code comparison result.

[0049] Specifically, the device unique identification code is input into the server of the Openthread gateway. When the server of the Openthread gateway receives the device unique identification code, the verification mechanism is triggered to compare the device unique identification code with the authentication identification code, and based on the comparison result, it is determined whether the device to be linked belongs to the list of devices to be connected in the system, thereby obtaining the identification code comparison result, which helps to confirm in real time whether the device can access the network.

[0050] It should be noted that the identification code comparison result can also be used to determine whether the location of the device is within the accessible range, and the access area of ​​the network access can be restricted according to the identification code comparison result to improve the security of network access.

[0051] S204: According to the identification code comparison result, the network connection access request with consistent comparison is processed for data connection.

[0052] Specifically, based on the identification code comparison results, the network connection access request of the device to be connected that is consistent with the comparison will be processed for data connection, such as establishing a connection channel between the device to be connected and the target access network segment through the Openthread gateway, and sending the feedback data of the corresponding network segment to the device to be connected according to the network connection access request.

[0053] In one embodiment, in order to better handle the load distribution of the Openthread gateway, such as Figure 4 As shown, step S20 also includes: S301: Obtain the node data transmission bandwidth value of the device to be connected that complies with the verification mechanism.

[0054] Specifically, based on the network connection access request of the device to be connected that meets the inspection mechanism, the data bit width between the device to be connected and the server of the Openthread gateway and the local data transmission frequency of the location of the device to be connected are obtained, and the node data transmission bandwidth value is the product of the data bit width of the server of the Openthread gateway and the local data transmission frequency.

[0055] S302: According to the preset load sharing rule of the Openthread gateway, the access processing time of the server of each Openthread gateway to the node data transmission bandwidth value is calculated.

[0056] Specifically, according to the load sharing rules of the Openthread gateway preset by the Openthread gateway, the size of the intranet feedback data is obtained, and the target transmission bandwidth required to transmit the corresponding intranet feedback data to the device to be connected is calculated; based on the target transmission bandwidth and the data transmission frequency of the current Openthread gateway server, the access processing time of each Openthread gateway server is calculated.

[0057] S303: According to the access processing time, the Openthread gateway is called to connect the server of the Openthread gateway with the best access processing time to the device to be connected, so as to facilitate the data transmission of the device to be connected to be diverted.

[0058] Specifically, according to the access processing time of each Openthread gateway server, all Openthread gateway servers are ranked by performance. For example, the shorter the access processing time, the higher the performance. According to the access processing time ranking result, the Openthread gateway with the shortest access processing time is linked to the device to be connected through the call of OPENOpenthread gateway, thereby achieving the purpose of dynamically selecting the server of the main Openthread gateway for data transmission, so that the server of the main Openthread gateway can divert the data transmission of the device to be connected. According to the actual data transmission needs of the device to be connected, the server of the main Openthread gateway can be dynamically selected for diversion processing, reducing the parallel data processing pressure of the server of the single-point Openthread gateway.

[0059] S30: Perform weighted polling on the servers of the Openthread gateway according to the connection node load value to obtain performance evaluation results of all Openthread gateway servers.

[0060] Specifically, according to the connection node load value of each Openthread gateway server, all Openthread gateway servers are assigned initial weight values, and all Openthread gateway servers are polled according to the weight from high to low. The higher the weight value, the greater the number of polling times, and the more times the access node requests. The performance evaluation results of all Openthread gateway servers are obtained based on the polling results. The more polling times, the better the performance of the Openthread gateway server.

[0061] S40: According to the performance evaluation result, the device to be connected is connected to the server of the Openthread gateway with the best performance evaluation result, so as to perform multi-node diversion transmission on the server of the Openthread gateway.

[0062] Specifically, Figure 5 As shown, step S40 includes: S401: According to the performance evaluation result, the server of the Openthread gateway with the best adaptability to the device to be connected is selected as the server of the main Openthread gateway.

[0063] Specifically, according to the performance evaluation results of all Openthread gateway servers within the framework of the Openthread gateway, all Openthread gateway servers are ranked by performance, and according to the ranking results, the Openthread gateway is called to select the Openthread gateway server that is most compatible with the device to be connected. For example, performance ranking can be performed according to the access processing time of intranet feedback data, or according to the idleness of the Openthread gateway server, so as to obtain the main Openthread gateway server connected to the device to be connected, adjust the weight of the main Openthread gateway server to the main Openthread gateway server, and adjust the weight of other Openthread gateway servers to the subordinate Openthread gateway servers.

[0064] S402: Link the device to be linked to the server of the main Openthread gateway, and process the network connection access request of the device to be linked.

[0065] Specifically, according to the unique identification code of the device to be linked, the device to be linked is linked to the server of the main Openthread gateway through the Openthread gateway, and the network connection access request of the device to be linked is processed by the server of the main Openthread gateway, such as allocating the corresponding number of node transmission traffic according to the network connection access request, and searching for the corresponding feedback data in the network segment of the corresponding network access access permission, and sending the intranet feedback data to the device to be linked according to the constructed node data transmission channel.

[0066] S403: According to the network connection access request, find a target intranet segment that matches the authority of the device to be connected, and receive feedback data of the target intranet segment.

[0067] Specifically, the server of the main Openthread gateway searches for the target network segment that meets the network access permission of the device to be connected in each network segment of the intranet based on the network connection access request, and receives feedback data from the target network segment based on the search result, and feeds back to the device to be connected through the node data transmission channel built by the Openthread gateway framework.

[0068] S404: According to the preset data transmission rule of the Openthread gateway, the feedback data is synchronously pushed to the server of the subordinate Openthread gateway which is secondary to the server of the main Openthread gateway.

[0069] Specifically, according to the preset data transmission rules of Openthread gateway, Openthread gateway will synchronously push feedback data to the server of subordinate Openthread gateway which is secondary to the server of main Openthread gateway, so as to perform synchronous backup processing on feedback data, and the linked device will receive feedback data sent by the server of main Openthread gateway, such as Openthread gateway will synchronize feedback data to multiple subordinate Openthread gateway servers through broadcast, so that when single point failure occurs in the server of main Openthread gateway, the server of subordinate Openthread gateway can be called in time through Openthread gateway to transmit data to the linked device, so as to reduce network access delay error in case of single point failure.

[0070] In one embodiment, in order to more timely switch the server of the main Openthread gateway where the data transmission failure occurs, such as Figure 6 As shown, step S404 also includes: S501: Obtain the node data transmission status between the device to be linked and the server of the main Openthread gateway in real time.

[0071] Specifically, after the node data transmission channel between the device to be connected and the server of the main Openthread gateway is established, the node data transmission status between the device to be connected and the server of the main Openthread gateway is monitored through the heartbeat detection mechanism preset by the Openthread gateway, such as sending detection packets to the server of the main Openthread gateway at regular time intervals, and receiving feedback data packets sent by the server of the main Openthread gateway. When the corresponding feedback data packet is not received within the preset time interval, it is determined that the node data transmission status is faulty.

[0072] S502: When a node data transmission state fails, authority values ​​are calculated for all slave Openthread gateway servers, and a slave Openthread gateway server with the best authority value is selected as the master Openthread gateway server.

[0073] Specifically, when the Openthread gateway detects that a failure occurs in the node data transmission status between the device to be linked and the server of the main Openthread gateway, it calculates the authority values ​​of all slave Openthread gateway servers within the framework of the Openthread gateway, such as the access processing time or data transmission performance of the slave Openthread gateway server. The higher the performance of the slave Openthread gateway server, the higher the authority value. Or, based on the idleness of the slave servers, such as the more load nodes each slave Openthread gateway server is attached to, the lower the idleness, and the corresponding authority value is also lower. It can be set according to actual needs, and the slave Openthread gateway server with the best authority value is selected as the main Openthread gateway server according to the authority value calculation result. The main Openthread gateway is mainly used to process feedback data, and other slave Openthread gateway servers adjust their own status to slave servers secondary to the main Openthread gateway server, and synchronize and back up the data of the main Openthread gateway server.

[0074] S503: According to the unique IP address of the device to be linked, a node data transmission channel is established between the device to be linked and the server of the main Openthread gateway.

[0075] Specifically, when a failure occurs in the node data transmission status between the device to be linked and the server of the main Openthread gateway, the Openthread gateway will automatically disconnect the node data transmission channel in the faulty state, and after electing the server of the slave Openthread gateway to replace the server of the original main Openthread gateway, it will build a node data transmission channel between the device to be linked and the server of the main Openthread gateway elected by the server of the slave Openthread gateway according to the unique IP address of the device to be linked, so as to facilitate timely receipt of feedback data from the server of the main Openthread gateway of the server of the slave Openthread gateway, thereby reducing the network access delay error caused by single point failure.

[0076] S504: Synchronously send the intranet feedback data to the device to be linked through the node data transmission channel, so as to reduce the data asynchrony caused by the single point failure of the server of the Openthread gateway.

[0077] Specifically, after the Openthread gateway has established a node data transmission channel between the device to be connected and the server of the main Openthread gateway, the Openthread gateway is called to synchronously send the intranet feedback data to the device to be connected through the node data transmission channel. The rebuilt node data transmission channel can reduce the interference of the original Openthread gateway server to the current data transmission after the fault is repaired, thereby reducing the data asynchrony caused by the single point failure of the Openthread gateway server and improving the data transmission stability of the Openthread gateway framework.
