Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
When a new node is accessed, an association request needs to be sent to a nearby node, and then the nearby node receives the association request and sends an association response frame to the new node, so that basic connection communication is established. The process is relatively blind, has no targeted access and no targeted connection, can generate an unstable condition when a new node is added, has low access success rate and long connection time, and the newly added node can not quickly respond to subsequent work. Moreover, the inventors have found that; when a new node is accessed, the information of the child nodes near the new node and the link quality are changed to a certain extent. The original mode of acquiring the running state information of the nodes is to exchange information among each other by sending corresponding frames without any identification. When a new node is accessed, it is not clear which nodes are suitable for accessing and which nodes can access the new node. Due to no targeted selection, a problem exists when a new node is accessed, and the access of the new node is influenced.
Therefore, the embodiment of the application provides a network connection method, device electronic equipment and a storage medium. As shown in fig. 1, the network connection method may be applied to a first node having access to a network, and the method includes:
step S101, acquiring the link quality, the signal strength and the number of the current access nodes;
in the embodiment of the invention, the link quality is the measurement condition of data packet loss in the communication process, the signal strength is the signal strength of the current network channel, and the number of the access nodes refers to the number of devices which have access to the nodes.
The link quality, the signal strength and the number of the current access nodes can be updated periodically and stored in the designated storage space, and the coloring identification determined based on the link quality, the signal strength and the number of the current access nodes can be more accurate due to the periodic update.
And step S102, determining coloring identification according to the quantity of the access nodes, the link quality and the signal intensity.
In the embodiment of the invention, the coloring identification is used for indicating the running state of the node, and coloring is carried out from poor to excellent in coloring distribution. Illustratively, the colored identifier may be a color identifier such as red, green, white, black, etc.; the invention adopts a coloring mechanism to color the running nodes of the mesh network, and the coloring is used for distinguishing the running state conditions of the child nodes under the current mesh network. Nodes in the same operation condition are assigned with the same color, and the color is divided into red (saturated operation state), green (excellent operation state), white (good operation state) and black (poor operation state). Neither red nor black will be the subject of new node access, and green and white will be the subject of new node access, where white takes precedence over green.
In this step, the number of access nodes, the link quality, and the signal strength may be respectively matched with the corresponding rules, and then the coloring identifier matched with each rule is searched in the preset corresponding relationship.
In an embodiment of the present invention, the embodiment of the present invention may perform level division on the number of access nodes, different link qualities, and different signal strengths in advance, divide different node number ranges, link quality levels, signal strength ranges, and the like, and preset coloring identifiers matching the different node number ranges, link quality levels, and signal strength ranges, as shown in table 1 below:
TABLE 1
In another embodiment of the present invention, the access ratio may be calculated according to the number of access nodes; and inquiring coloring identification corresponding to the access ratio, the link quality and the signal intensity in a preset parameter identification corresponding relation.
In the embodiment of the present invention, the access proportion may be a ratio of the number of access nodes to the total number of nodes allowed to be accessed by the first node.
The embodiment of the invention can previously grade access occupation ratios, different link qualities and different signal strengths, divide different node quantity ranges, link quality levels, signal strength ranges and the like, and preset coloring marks matched with different access occupation ratios, link quality levels and signal strength ranges, as shown in the following table 2:
TABLE 2
| Ratio of nodes | Link quality class | Range of signal strength | Colored identification |
| Node ratio 1 | Class 1 | Signal strength range 1 | Red colour |
| Node occupation ratio 2 | Class 2 | Signal strength range 2 | Green colour |
| Node ratio 3 | Class 3 | Signal strength range 3 | White colour |
| Node occupation ratio 4 | Class 4 | Signal strength range 4 | Black color |
| Node ratio of 5 | Grade 5 | Signal strength range 5 | Blue color |
| Node ratio 6 | Grade 6 | Signal strength range 6 | Yellow colour |
In practical applications, the examples of the coloring identifier matching any of the different node number ranges, link quality levels, and signal strength ranges are as follows:
red (run state saturated): namely, the node access number is already 1 (saturation), the link quality is normal, and the signal strength is normal.
Green (excellent running state): the number of accessed nodes is one fifth, and the link quality and the signal strength are excellent.
White (good running condition); the number of the access nodes reaches three fifths, and the link quality and the signal strength are normal.
Black (poor running state): the link quality, signal strength are lower than normal, regardless of the number of accesses.
Step S103, broadcasting the coloring identification, or returning the coloring identification when receiving the identification acquisition request;
in this step, the coloring identifier may be automatically broadcast according to an actual setting condition, or whether the identifier obtaining request is received is automatically detected, and when the identifier obtaining request is received, the coloring identifier is returned to a sender of the identifier obtaining request.
And step S104, if a node association request is received, returning a node association response and establishing network connection, wherein the node association request is sent after a second node which does not access the network determines that the coloring identification meets the association condition.
The embodiment of the invention firstly obtains the link quality, the signal intensity and the number of the access nodes of the current accessed node, then determines the coloring identification according to the number of the access nodes, the link quality and the signal intensity, the coloring identification is used for indicating the running state of the node, and then broadcasts the coloring identification, or returns the coloring identification when receiving the identification obtaining request; and if receiving a node association request, returning a node association response and establishing network connection, wherein the node association request is sent after a second node which is not accessed to the network determines that the coloring identifier meets the association condition.
The embodiment of the invention can automatically determine the coloring identification according to the number of the access nodes, the link quality and the signal strength and inform the second nodes which are not accessed to the network, so that the second nodes which are not accessed to the network can pointedly select the optimal first node to access according to the coloring identification, and the access success rate is improved.

The link quality is excellent, which means that the current link is in a stable state, and data transmission and the like are all normal levels.
Step 202, acquiring the downlink quality of a downlink network link where the downlink network link is located;
step 203, determining the link quality according to the uplink quality and the downlink quality.
In this step, determining the link quality from the uplink quality and the downlink quality includes:
if the uplink quality is greater than a preset first threshold and the downlink quality is greater than a preset first threshold, determining that the link quality is excellent;
or, if the uplink quality is less than a preset second threshold or the downlink quality is less than a preset second threshold, determining that the link quality is poor, where the preset second threshold is less than the preset first threshold;
or, if the uplink quality is greater than a preset second threshold and the downlink quality is greater than a preset second threshold, determining that the link quality is medium.
That is, it is required that both the uplink quality and the downlink quality are excellent to determine that the link quality is excellent, and if one of the uplink quality and the downlink quality is poor, the link quality is poor, and if neither the uplink quality nor the downlink quality is good (that is, if one is medium, one is excellent, or both are medium), the link quality is medium.
The embodiment of the invention comprehensively determines the link quality according to the uplink quality and the downlink quality, improves the accuracy of the determined link quality and further improves the accuracy of the determined coloring identification.
