Referring to fig. 2, fig. 2 is a data backup method for an internet of things repeater, which is implemented under a network architecture shown in fig. 1, where as shown in fig. 1, one repeater may be connected to a plurality of terminals of the internet of things, and the repeater may specifically be a mobile phone that opens a hot spot, a personal computer that provides wireless connection, or a conventional hot spot device such as a router, and the method is shown in fig. 2 and includes the following steps:
step S201, the first Internet of things repeater detects the probability of the fault of the first Internet of things repeater, and if the probability is larger than a set threshold value, the first Internet of things repeater determines that a fault sign appears.
The implementation method of the step S201 may specifically be:
the first internet-of-things relay may determine the probability of the failure by detecting a packet loss rate of the data packet, and certainly, in practical application, the probability of the failure may also be detected by using other methods, for example, detecting an uploading network speed and the like.
Step S202, the first Internet of things repeater sends the data of the Internet of things terminal stored in the cache to a second backup Internet of things repeater or a third backup Internet of things repeater for data backup.
The implementation method of the step S202 may be:
the first internet of things terminal sends the data of the internet of things terminal stored in the cache to the AP, and the AP forwards the data of the internet of things terminal stored in the cache to the second backup internet of things repeater or the third backup internet of things repeater so as to realize data backup.
Each manufacturer of the type of the internet of things terminal in the step S202 may set according to its own condition, for example, the internet of things terminal may specifically include: intelligent electric light, intelligent TV, intelligent cleaning equipment, intelligent sleep equipment, intelligent supervisory equipment etc. the form of its performance can be various, for intelligent electric light for example, this intelligent electric light includes but not limited to: intelligence desk lamp, intelligence ceiling lamp, equipment such as intelligence wall lamp, for example to intelligent television, it can be three stars brand intelligent television, of course it also can be sharp brand intelligent television, for example to intelligent cleaning equipment, it can be, intelligence robot of sweeping the floor, of course it can also include equipment such as intelligent dust catcher, intelligent garbage disposer, for example to intelligent sleep equipment, it can be: for example, for an intelligent monitoring device, the intelligent monitoring device may be an intelligent sphygmomanometer, an intelligent thermometer, or the like, and the specific form, number, or type of the internet of things terminal is not limited in the present invention.
In the step S202, the data transmission mode from the terminal of the internet of things to the relay may be a mode of sending a data packet through wireless connection, where the wireless mode includes but is not limited to: wireless modes such as bluetooth, Wireless Fidelity (WIFI) and Zigbee, wherein the WIFI needs to comply with the standard of ieee802.11b.
It should be noted that the internet of things and the relay are only for the wireless relay, because the internet of things has a large number of devices to access, and for the relay, if the relay is connected by wire, the number of terminals to access is limited, and for the home, the terminals are connected by wire, which is not imaginable for the wiring of the home user, and in addition, the cost of the wire is very high, so the connection between the terminal of the internet of things and the relay in the technical solution of the present invention is only limited to wireless connection.
The second backup internet-of-things repeater and the first internet-of-things repeater belong to a data double backup group; the third backup internet of things repeater and the first internet of things repeater belong to another data double backup group. Two internet of things repeaters in the backup group are provided with backup settings, and if one internet of things repeater is about to fail in the same backup group, the other internet of things repeater in the backup group can send cached data to backup the cached data.
Optionally, the implementation method of step S202 may specifically be:
the first internet-of-things repeater receives a second cache allowance and a second fault probability of the second backup internet-of-things repeater sent by the second backup internet-of-things repeater, and the first internet-of-things repeater receives a third cache allowance and a third fault probability of the third backup internet-of-things repeater sent by the third backup internet-of-things;
when the second cache allowance is larger than the third cache allowance and the second failure probability is lower than the set threshold, the first internet of things repeater transmits more than 50% of the data of the internet of things terminal to a second backup internet of things repeater and transmits the remaining data of the internet of things terminal to a third backup internet of things repeater, the first internet of things repeater transmits a first switching message to the internet of things terminal, and the first switching message is used for indicating the internet of things terminal to be switched to the second backup internet of things repeater;
when the second cache allowance is larger than the third cache allowance and the second failure probability is higher than the set threshold, the first internet of things repeater transmits the data of the internet of things terminal to the third backup internet of things repeater for backup, the first internet of things repeater transmits a second switching message to the internet of things terminal, and the second switching message is used for indicating the internet of things terminal to be switched to the third backup internet of things repeater; the third failure probability is lower than the set threshold.
The arrangement of the scheme is mainly to avoid the situation that backup occurs again when the failure probability of the internet of things relay station after data transmission is too high, and for the backup grouping, because only two internet of things relay stations exist, if the failure probability of the two internet of things relay stations is too high, the situation that the backup internet of things relay station is not selectable may occur, and the mode can also avoid the situation.
Optionally, the implementation method of step S202 may specifically be:
and the first internet-of-things repeater receives fault probabilities sent by other internet-of-things repeaters, if the fault probability of the second backup internet-of-things repeater is higher than a set threshold, the first internet-of-things repeater exits the data double backup group, the first internet-of-things repeater and a fourth internet-of-things repeater are reconstructed into a further data double backup group, the fault probability of the fourth internet-of-things repeater is lower than the set threshold, and the other internet-of-things repeaters comprise all internet-of-things repeaters except the first internet-of-things repeater in the internet-of-things local area network.
The technical scheme is used for updating the backup grouping, and mainly avoids the situation that when backup is needed, the other Internet of things repeater has higher fault probability and cannot realize backup, so that equipment with higher fault probability, which meets the requirements in the middle of the backup grouping, needs to be removed and updated.
Optionally, the implementation method of step S202 may specifically be:
the first internet-of-things repeater receives the cache allowance sent by other internet-of-things repeaters, if the cache allowance of the second backup internet-of-things repeater is lower than the data of the internet-of-things terminal stored in the cache, the first internet-of-things repeater exits the data double backup group, the first internet-of-things repeater and a fifth internet-of-things repeater are reconstructed into a further data double backup group, the fault probability of the fifth internet-of-things repeater is lower than the set threshold, and the other internet-of-things repeaters include all internet-of-things repeaters except the first internet-of-things repeater in the internet-of-things local area network.
The technical scheme is to avoid the problem that the backup of the data of the relay station of the internet of things cannot be realized due to too much cached data.
According to the method provided by the figure 2, when the probability of the failure of the first internet of things repeater is detected, and when the probability of the failure exceeds a set threshold value, a backup request is sent to the other internet of things repeater in the backup group to backup the data of the internet of things terminal stored in the cache, so that the data backup is realized, the failure resistance of the internet of things repeaters is improved, and the user experience is improved.

The implementation method of the step S302 may be:
the first Internet of things repeater receives a second cache allowance of the second backup Internet of things repeater sent by the second backup Internet of things repeater in a wireless mode; and the first Internet of things repeater receives the third cache allowance of the third backup Internet of things repeater sent by the third backup Internet of things in a wireless mode.

Step S303, when the second cache allowance is larger than the third cache allowance, the first Internet of things repeater sends more than 50% of the data of the Internet of things terminal to a second backup Internet of things repeater, and sends the residual data of the Internet of things terminal to a third backup Internet of things repeater.
The second backup internet-of-things repeater and the first internet-of-things repeater belong to a data double backup group; the third backup internet of things repeater and the first internet of things repeater belong to another data double backup group. Two internet of things repeaters in the backup group are provided with backup settings, and if one internet of things repeater is about to fail in the same backup group, the other internet of things repeater in the backup group can send cached data to backup the cached data.
