Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Please refer to fig. 1, which is a flowchart illustrating a wireless networking method according to an embodiment of the present invention; the method comprises the following steps:
s1, acquiring networking information of a wireless network;
s2, caching the networking information in a storage unit;
specifically, step S2 further specifically includes: caching the networking information in a storage unit, dividing the storage unit into a plurality of storage units by taking 4 bytes as a unit, and storing CHANLIST and PANID fields in each storage unit, wherein the lengths of the CHANLIST field and the PANID field are both 2 bytes. The caching method has the advantages of saving storage space and efficiently saving only the minimum information required by connecting to the network.
And S3, reading the networking information from the storage unit, and connecting to the wireless network by using the networking information.
Further, in this embodiment, the "caching the networking information in the storage unit" and the "reading the networking information from the storage unit" are a multi-write and multi-read mode, where the multi-write and multi-read mode specifically includes:
acquiring CHANLIST and PANID field information for multiple times, and sequentially caching in a storage unit;
when the networking information is read from the storage unit, one storage unit data is sequentially read, networking is tried according to CHANLIST and PANID field information in the storage unit data, and if the networking fails, the CHANLIST and PANID field information of the next storage unit is sequentially read.
The advantage of the write-many-read mode is that connection failure caused by error code in the transmission process can be effectively avoided through the simple and easy operation design.
In another embodiment, the "caching the networking information in the storage unit" and the "reading the networking information from the storage unit" are in a multi-write and single-read mode, where the multi-write and single-read mode specifically includes:
acquiring CHANLIST and PANID field information for multiple times, and sequentially caching in a storage unit;
reading N storage unit data from the storage unit in sequence at one time, wherein N is a preset number, judging the consistency of CHANLIST and PANID field information in the N storage unit data, directly trying to network if the CHANLIST and PANID field information are completely consistent, and selecting the CHANLIST and PANID field with the highest repetition number to try to network if the CHANLIST and PANID field information are not completely consistent.
The write-many and read-once mode has certain intelligent networking advantages and can provide better user experience. In another embodiment of optimizing the write-once read-many mode, when determining the consistency of the CHANLIST and PANID field information in the N memory unit data, the method further includes a further determination and operation: if the repetition number of two or more groups of CHANLIST and PANID fields is equal or the difference is smaller than a preset threshold value, the RSSI (received signal strength indicator) strength of the network corresponding to each group of CHANLIST and PANID fields is judged, and the strongest one is selected as the network to be added and networking is attempted. This optimized implementation will further increase the degree of intelligence.
In some other optimized embodiments, in the write-many read mode or the write-many read mode, the number M of groups of taken and cached CHANLIST and PANID fields ranges from 10 to 16000. The limitation of the value range is based on the practical consideration of the method applied to a specific practical process, and when the number M of the acquired groups is less than 10, the data quantity is not enough to achieve the purpose of improving the accuracy and intelligence of consistency judgment; when the value of M is too large, unnecessary stress is easily applied to the transmission rate and the storage capacity, and therefore, it is most effective and efficient to define a certain interval for M.
In some other preferred embodiments, N in the write-once-read-once mode satisfies the condition: n is not more than a M, wherein a represents the estimated value of the transmission failure probability and has the value range of 0.1-1. More preferably, a is 0.8. The preferred embodiments relate the value of N to the estimation/prediction of the transmission failure probability and the value of M to obtain a specific limited range of the number of read groups N, and have higher recognition efficiency and stronger applicability.
In fact, the wireless networking method in this scheme relies on the joint operation of another device: that is, as described in step S1, "acquiring networking information of a wireless network", it means that there is no need to have a providing device of networking information of a wireless network, and it is not referred to as a control end herein. In conjunction with the control terminal, the method also has an optimally extended run-in comparison scheme, which is briefly described below.
The control terminal sends a group of identification signals with random time delay, and then the acquisition terminal is provided with a display component which can have a light-emitting function or a function of visible signals of other people. When the acquisition end receives the group of signals, the identification signals sent by the control end and the display signals of the display components have a one-to-one corresponding relation according to the preset, so that when the display components send the display signals one by one according to the received identification signals, a user can judge whether to connect to the same network according to the consistency of the display signals.
Further, the random delay value between one group and another group of the identification signals is set to be 3-15 seconds, which causes inconvenience for a user to wait due to too long time, and the computing processing resources may be excessively occupied due to too short time. And the signal and the interval between the signals in the group of identification signals are 100ms-1s, which is a time range relatively conforming to the visual acceptance of the user.

Further, in the wireless networking device, N in the multiple write-once read mode satisfies the condition: n is not more than a M, wherein a represents the estimated value of the transmission failure probability and has the value range of 0.1-1.
Further, in the wireless networking device, a is 0.8.
