In this embodiment, the first access point and the backup access point are access points at the same node, have the same function, and can both be connected to the internet of things as access points, and the backup access point of the first access point is used for backing up the cache data of the first access point. The backup access point can be a working access point or an idle access point, and when the backup access point is only used for the backup function, the radio frequency function of the backup access point can be closed, and only the storage function of the backup access point is used, so that the energy consumption is saved. It should be noted that there are at least two backup access points, and the cache data of the first access point is backed up to multiple backup access points at the same time.
In one embodiment, the first access point acquires access point identification information of a second access point and a third access point, which are backup access points of the first access point, from an upper management device of the first access point, wherein the upper management device includes a gateway server.
The access point identification information of the second access point comprises Bluetooth identification information of the second access point, IP address information of the second access point, MAC address information of the second access point or equipment identification code information of the second access point.
The access point identification information of the third access point comprises Bluetooth identification information of the third access point, IP address information of the third access point, MAC address information of the third access point or equipment identification code information of the third access point.
In one embodiment, the types of the access point identification information of the second access point and the third access point acquired by the first access point are different, and the types of the connections established between the first access point and the second access point and the third access point are different, if the acquired access point identification information is the device identification code information of the second access point, the connection established with the second access point is an infrared connection, and if the acquired access point identification information is the IP address information of the third access point, the connection established with the third access point is a Wifi connection.

In this embodiment, the priority of the backup access point may be calculated according to the processing unit utilization, the memory utilization, and the transmission data amount of the backup access point. One of the calculation methods is as follows: assuming that the processing unit utilization rate of the backup access point is a, the memory utilization rate is B, the transmission data volume is C, and the priority is W, the following formula is used:
W＝a1·A+a2·B+a3·C
is calculated to obtain wherein a1+a2+a31. It should be noted that a here1、a2、a3The specific value of (a) can be set according to the operation condition of the access point, or recommended setting, for example, setting a1＝50％，a2＝30％， a3＝20％。
In this embodiment, the priorities of the backup access points are ranked, and for facilitating understanding of the present solution, the backup access point with the highest priority is referred to as a second backup access point, and the backup access point with the priority next to the second access point is referred to as a third access point. And after the first access point fails, starting the radio frequency function of the second access point, and connecting the second access point to the network for communication. Meanwhile, the third access point is used as a backup access point of the second access point, and the cache data of the second access point is backed up to the third access point, so that normal communication of the access points is guaranteed, and the reliability of the Internet of things is improved.
It should be noted that the number of backup access points in this embodiment may be multiple, and is not limited to two listed in this embodiment. When the number of the backup access points is more than two, the backup access point with the highest priority is still selected as the second access point, and other backup access points are used as the backup access points of the second access point. For example, in an internet of things, there are 4 access points at a node, which are access point 1, access point 2, access point 3, and access point 4, where access point 3 is the first access point, and communicates in the network, and the other three access points are all used as backup access points for access point 3. In a certain communication process, the access point 3 is in failure, and the priorities of the access point 1, the access point 2 and the access point 4 are calculated. Suppose that according to the above formula:
W＝a1·A+a2·B+a3·C
calculating to obtain a1＝50％，a2＝30％，a320% by weight. Thus, the priority of the access point 1 is 89, the priority of the access point 2 is 75, and the priority of the access point 4 is 67, the three calculation results are ranked, the access point 1 with the highest priority is selected as the second access point, and the access point 2 and the access point 4 are used as backup access points of the access point 1. Therefore, normal communication of the access points is guaranteed, and the reliability of the Internet of things is improved.
Step S108: and switching the terminal of the internet of things connected with the first access point to the second access point, and sending the cache data of the second access point to a third access point serving as a backup access point of the second access point.
In this embodiment, after the first access point fails, a MAC address of the second access point is broadcast to the terminal of the internet of things, where the MAC address is also referred to as a physical address or a hardware address and is used to define a location of the network device, each access point has an individual MAC address, and the terminal of the internet of things can initiate a connection request to the second access point after receiving the MAC address of the second access point.
In one embodiment, after the first access point fails, an equipment identifier of the internet of things terminal connected with the first access point is acquired, where the equipment identifier is identification information which is embedded in an internet of things terminal equipment chip and is used for distinguishing other equipment, and the equipment identifier cannot be changed after the equipment leaves a factory, and includes information such as a serial number of a manufacturer, a model of the equipment, and an MAC address of the equipment. And generating the equipment authentication code according to the equipment identification information, namely converting the information into a character code form, such as a specific format of 'serial number-model number-MAC address', and facilitating the reading of other equipment. And then, the generated equipment authentication code of the terminal of the internet of things connected with the first access point is sent to the second access point. When the second access point receives the connection request of the Internet of things terminal, the equipment identification of the Internet of things terminal is obtained, the equipment information is read out from the equipment identification and is matched with the equipment authentication code stored in advance, and when the equipment identification of the Internet of things terminal is successfully matched with the stored equipment authentication code, the Internet of things terminal can be received for connection. By storing the equipment authentication code and directly connecting after successful matching judgment, the processes of session information authentication, key pairing and the like on the equipment again can be avoided when the terminal of the Internet of things initiates a connection request to the second access point, and therefore the communication efficiency of the Internet of things is improved.
It should be noted that, the matching between the device identifier of the terminal of the internet of things and the stored device authentication code may be successfully included in various cases, for example, the serial number, the model number, and the MAC address are all the same; or only if the identification serial numbers are the same, the equipment identification is judged to be successfully matched with the stored equipment authentication code; or only more than a certain percentage of characters in the character string match. By the method, the workload of data processing can be reduced, and the efficiency is improved.
In one embodiment, a national channel code corresponding to the first access point is obtained according to the positioning information of the first access point, and a wireless network channel frequency band accessed by the first access point is adjusted according to the national channel code and the corresponding relationship between the national channel code and the wireless network channel frequency band. According to the frequency band range divided by 802.11, the frequency band ranges are respectively 2.4GHz and 4.9/5.8GHz, each frequency band is divided into a plurality of channels, different countries make policies to use the frequency bands by themselves, namely, each country has a channel range corresponding to the country. The frequency range of 2.4GHz is the currently common frequency band, the frequency range is 2.400-2.4835GHz, the total bandwidth is 83.5M, the frequency range is divided into 14 sub-channels, the width of each sub-channel is 22MHz, the center frequency points of adjacent channels are separated by 5MHz, the adjacent channels have frequency overlapping (for example, the frequency overlapping exists between the channel 1 and the channels 2, 3, 4 and 5), only 3 (1, 6 and 11) non-interfering channels exist in the whole frequency band, and the national channel code of China is 1-13. For example, if the positioning information is displayed in china, the first access point acquires the national channel codes 1 to 13 of china, and selects a wireless network frequency band for communication, thereby avoiding the problem of communication quality reduction caused by mismatching of access point equipment and channel codes of different countries.
In one embodiment, the load amount of the first access point is detected, and when the load amount of the first access point exceeds a preset load threshold, the internet of things device or the repeater connected with the first access point is switched to the second access point. In this embodiment, the load capacity of the first access point can be described by the data volume sent and received by the first access point every second, in a local area network, after the internet of things terminal searches for a plurality of access points, the access points with better signal strength are mainly selected for connection, once most of the internet of things terminals are connected to the same access point, the load capacity of the access points is increased, when the load capacity reaches a certain degree, the normal operation of the access points is affected, and the transmission rate is reduced. Setting a proper load threshold, when detecting that the load of the access point is higher than the threshold, for example, the bandwidth provided by the first access point is 10Mbps, the set load threshold is 8Mbps, and when the sum of the bandwidths occupied by the accessed internet of things terminal or repeater exceeds 8Mbps, switching the internet of things terminal or repeater to the second access point, thereby avoiding network transmission function failure caused by excessive load.
In one embodiment, the implementation of the present invention is set forth below in a specific application scenario. In the application scenario, there are 3 access points at a node in the internet of things, which are respectively an access point J, an access point K, and an access point L, where the access point J is a first access point and communicates in the network, and the other two access points are both used as backup access points of the access point J, and only the storage function is turned on.
In a certain communication process, the access point J breaks down, the priority of the access point K is higher than that of the access point L according to the priority calculation results of the access point K and the access point L, the access point K is set as a second access point, and the access point L is set as a backup access point of the access point K.
Before the access point J breaks down, the access point J is connected with the Internet of things terminal 1 and the Internet of things terminal 2, and at the moment, the radio frequency function of the access point K is started. The access point K obtains and stores the equipment authentication codes of the terminal 1 and the terminal 2 of the Internet of things as 001-A1070-00010010 and 011-BC79-00101100 respectively. Then, the access point K broadcasts the MAC address '00-01-6C-06-A6-29' of the access point K to the terminal 1 of the Internet of things and the terminal 2 of the Internet of things.
And after receiving the MAC address, the Internet of things terminal 1 and the Internet of things terminal 2 initiate a connection request to the access point K according to the MAC address.
The access point K acquires that the equipment identification information of the terminal 1 of the Internet of things and the equipment identification information of the terminal 2 of the Internet of things are '001-A1070-00010010' and '011-BC 79-00101100' respectively according to the connection request of the terminal 1 of the Internet of things and the terminal 2 of the Internet of things, is the same as the equipment authentication codes stored before, judges that the matching is successful, and receives the connection of the terminal 1 of the Internet of things and the terminal 2 of the Internet of things.
