In the embodiment of the invention, the node network access method is applied to a communication networking system, and the communication networking system comprises a central node, at least one member node and at least one non-member node to be networked, wherein the central node and the at least one member node are deployed in the same wireless network. The central node is used for configuring each non-member node to be accessed to the wireless network so as to configure the non-member node as a member node of the wireless network, and enable the non-member node to be successfully accessed to the wireless network; the member nodes are data nodes used for data communication in the wireless network, and the member nodes are in communication connection with the central node so as to perform data communication under the control of the central node. The specific flow and steps of the node network accessing method shown in fig. 1 are explained in detail below.
In the embodiment of the present invention, the node network access method includes the following steps:
step S210, the central node sends a network access sensing frame to each member node, so that each member node forwards the network access sensing frame.
In this embodiment, the central node senses whether the member node that has received the network access sensing frame is in the wireless network by periodically sending the network access sensing frame to each member node. Specifically, after completing the configuration of the member node, the central node adds a corresponding member identification field for the member node in the network access sensing frame. And when the central node sends the network access sensing frame to the corresponding member node, the member node fills the corresponding network configuration information of the member node in the wireless network in the corresponding member identification field in the network access sensing frame, and forwards the network access sensing frame to other member equipment so as to forward the network access sensing frame through other member nodes, or directly forwards the network access sensing frame to the central node. And the central node compares the content filled in the corresponding member identification fields in the received network access sensing frame with the prestored network configuration information of the corresponding member nodes by reading the content, and judges that the member nodes are in the wireless network when the content is the same as the prestored network configuration information of the corresponding member nodes. The network configuration information is used for representing basic communication parameters corresponding to the corresponding nodes in the wireless network, and the network configuration information comprises communication time slots, communication addresses and father node addresses of the corresponding member nodes. The network access sensing frame is reserved with a network access identification field corresponding to a non-member node, the network access identification field is used for the non-member node to fill in corresponding network access information, the network access information is node information corresponding to the non-member node when the non-member node is accessed to the wireless network, and the network access information comprises a communication time slot, a communication address and a father node address corresponding to the non-member node.
In this embodiment, the central node may configure a preset forwarding order among the member nodes, so that after receiving the network access sensing frame and executing corresponding operations, each member node forwards the network access sensing frame according to the preset forwarding order. Specifically, the central node broadcasts and sends a network access sensing frame to each member node, so that each member node can forward and return the network access sensing frame to the central node according to the preset forwarding sequence after receiving the network access sensing frame and executing corresponding operations, and the central node reads and identifies the received network access sensing frame to judge whether each member node is in the wireless network. And the network access sensing frame finally received by the central node covers the network configuration information corresponding to each node in the wireless network.
In this embodiment, network access sensing frame forwarding may also be performed between member nodes, a forwarding process of the network access sensing frame forwarding may also be broadcast forwarding, and when each member node forwards the network access sensing frame, network configuration information and working state information of the member node itself are recorded in a member identification field corresponding to the network access sensing frame, and the member node forwards the network access sensing frame based on the recorded network access sensing frame.
Step S220, a non-member node scans and monitors a network access sensing frame, analyzes the monitored network access sensing frame after monitoring the network access sensing frame to obtain networking elements of a wireless network, and obtains network access information corresponding to the non-member node in the wireless network according to the networking elements.
In this embodiment, each member node is configured with a number different from that of other member nodes by the central node, and the non-member node may perform scanning and monitoring on the network access sensing frame forwarded between the member nodes, acquire the network access sensing frame after monitoring the network access sensing frame, analyze the network access sensing frame to obtain a networking element of the wireless network, and obtain network access information corresponding to the non-member node in the wireless network according to the networking element.
In this embodiment, the networking element of the wireless network includes network configuration information of each current member node of the wireless network, and the step of analyzing the intercepted network access sensing frame to obtain the networking element of the wireless network includes:
and reading the filled contents in the member identification fields corresponding to the member nodes in the acquired network access sensing frame to obtain the network configuration information of the member nodes. The network configuration information of each member node obtained by the non-member node is the network configuration information of the member node which fills in the content in the member identification field corresponding to the network access perception frame.
Fig. 2 is a schematic flow chart illustrating the sub-steps included in step S220 shown in fig. 1. In this embodiment, the step of obtaining the network access information corresponding to the non-member node in the wireless network according to the networking element in the step S220 includes a substep S221 and a substep S222:
and a substep S221, recognizing the communication time slot of the non-member node in the whole wireless network according to the communication time slot of each member node.
In this embodiment, the non-member node may recognize, according to the number of the member identification fields in the network access sensing frame and the read communication time slots of each member node, the communication time slot of the non-member node in the entire wireless network, and determine that the communication time slot is the communication time slot corresponding to the non-member node when no other node performs data communication in the recognized communication time slot by detecting whether the node performs data communication in the recognized communication time slot. Wherein the communication time slots of the non-member nodes throughout the wireless network are ordered after the communication time slots of the member nodes registered with the network in said wireless network.
And a substep S222, selecting the communication address of the member node with the strongest signal strength with the non-member node as the father node address of the non-member node.
In this embodiment, when the non-member node performs the frame sensing for sensing frame access, the signal strength between the non-member node and each member node in the sensing range of the non-member node is detected, so that the member node with the strongest signal strength with the non-member node is selected as the parent node of the non-member node, and the communication address of the selected member node is used as the parent node address of the non-member node. Wherein the communication address may be an identification address, e.g. a MAC address, of the corresponding node.
Step S230, the non-member node fills the network access information into the network access identification field of the network access sensing frame, sends the filled network access sensing frame in the communication time slot corresponding to the non-member node, and returns the network access sensing frame to the central node through the corresponding member node.
In this embodiment, after obtaining the network access information corresponding to the non-member node, the non-member node fills the network access information in the network access identification field of the network access sensing frame, and sends the filled network access sensing frame in the communication time slot corresponding to the non-member node, so as to return the network access sensing frame to the central node via the member node under the action of the corresponding member node.
The step of sending the filled network access sensing frame in the communication time slot corresponding to the network access sensing frame and returning the network access sensing frame to the central node through the corresponding member node comprises the following steps:
and sending the filled network access sensing frame to a matched member node based on the father node address of the non-member node in a corresponding communication time slot, so that the member node forwards the network access sensing frame to the central node according to a preset forwarding sequence. The preset forwarding sequence may be a preset sequence for forwarding the network access sensing frame among the member nodes, or may be a sequence for directly returning the network access sensing frame received by the current member node to the central node.
And step S240, the central node reads information of the network access sensing frame returned by each member node, and configures the corresponding non-member node as a member node in the wireless network when the network access information of the non-member node is read in the corresponding network access identification field.
In this embodiment, after receiving a network access sensing frame forwarded and returned by each member node, the central node reads and identifies a network access identification field in the received network access sensing frame, so as to determine whether a non-member node exists in the wireless network currently according to the read content, and configures the non-member node when the non-member node exists, so as to configure the non-member node as a member node in the wireless network, thereby implementing fast network access of a node to be accessed.
Wherein the step of configuring the corresponding non-member node as a member node in the wireless network comprises:
and configuring the corresponding non-member node based on the network access information of the corresponding network access sensing frame in the network access identification field, and newly adding the corresponding member identification field for the configured non-member node in the network access sensing frame after the configuration is finished so as to add the non-member node into the wireless network.
In this embodiment, if the network access identification fields in all the network access sensing frames received by the central node are empty, then no non-member node exists in the wireless network.
In this embodiment, if the content in the network access identification field in each network access sensing frame read by the central node is not empty, a non-member node that needs to access the wireless network exists in the wireless network, and the central node configures the corresponding non-member node according to the network access information of each non-member node in the wireless network obtained through identification.
In this embodiment, after the central node completes configuration of a corresponding non-member node, a member identification field corresponding to the configured non-member node is newly added in a network access sensing frame, and the network access condition of each member node in the wireless network is sensed by the modified network access sensing frame, where each member node in the wireless network includes a member node converted from the non-member node.
