The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.

In order to solve the technical problems of transmission data loss and network operation abnormity caused by the failure of the repeater, in one embodiment, a processing method of the failed repeater is particularly provided. The method may be implemented in dependence on a computer program that is executable on a computer device based on the von neumann architecture, which may be a hypervisor or a virtual device hypervisor of the repeater.

The network framework of the internet of things shown in fig. 1 comprises a server, a gateway, M access points, N repeaters and a plurality of internet of things terminals, wherein the access points are connected with the gateway through the ethernet or network forms such as 2G, 3G and 4G, the repeaters are connected with the plurality of internet of things terminals and the access points, the internet of things terminals transmit collected data through the repeaters, and the data are uploaded to the server through the access points and the gateway equipment to exchange the data.

The computer system is based on a repeater subsystem, and the repeater subsystem shown in fig. 2 at least includes a first repeater, a second repeater and a third repeater, where the backup node of the first repeater at least includes the second repeater and the third repeater, the first repeater and the backup repeater are repeaters at the same node, and have the same function, and both of the first repeater and the backup repeater can be used as repeaters to be connected to the internet of things, and the backup repeater of the first repeater is used for backing up the cache data of the first repeater. The backup relay may be an active relay or an idle relay. It should be noted that, in order to improve the fault-tolerant capability of the network, there may be more than two backup repeaters, and the cache data of the first repeater is backed up to multiple backup repeaters simultaneously.

Specifically, as shown in fig. 3, a backup method for an internet of things repeater includes:

step S101: and acquiring a backup repeater of the first repeater, and backing up the cache data of the first repeater to the backup repeater.

The repeater is mainly used to enhance the coverage of the wireless signal of the access point AP, for example, the repeater may be a Wi-Fi signal amplifier. Setting a backup repeater for the repeaters in the network environment of the Internet of things in advance, and obtaining the repeaters in the repeater subsystem to obtain a first repeater which at least comprises two repeaters, namely a second repeater and a third repeater. The backup repeater of the first repeater is obtained, and the data cached on the first repeater is backed up to the backup repeater, that is, the cached data of the first repeater can be obtained by reading the stored data on the second repeater and the third repeater, so that the data is ensured not to be lost. The cache data on the first repeater comprises data collected by the terminal of the internet of things and data sent to the terminal of the internet of things by the server.

Optionally, when the size of the capacity of the cache data of the first relay reaches a preset capacity threshold or the time recorded by the timer reaches a preset backup interval time, the step of backing up the cache data of the first relay to the backup relay is performed. Therefore, the situation that the backup fails because the first repeater cannot be connected with the backup repeater when the first repeater fails is avoided, and the fault resistance is improved.

That is, the repeater subsystem backs up the buffered data when its capacity is greater than or equal to the load threshold. Or a backup interval time threshold is set, and the cache data is backed up at intervals, so that the operation load and the network maintenance cost of the Internet of things network caused by real-time backup are reduced, and data loss caused by the failure of the first repeater is avoided.

For example: if the preset capacity threshold is 10M, performing backup on the second repeater when the capacity of the cache data is 10M; if the preset backup interval time is 5 minutes, the cache data on the first repeater is backed up every 5 minutes. Further, when the capacity of the cache data of the first repeater reaches a preset capacity threshold or the time recorded by the timer reaches a preset backup interval time, calculating the priority of the backup repeater according to the performance parameters of the backup repeater of the first repeater; and backing up the cache data of the first repeater according to the priority of the backup repeater. And performing backup according to the priority, thereby improving the backup efficiency.

The performance parameters of the backup repeater include: processing unit utilization, memory utilization, input/output load information, and the number of backup jobs being run. Specifically, the backup repeater may first establish a data structure including the four information, then collect load sampling information of the backup repeater itself, and record the load sampling information into the established data structure; sending the recorded load sampling information to a processor in the Internet of things for processing fault accidents through the local Ethernet; and the processor performs weighted calculation according to the performance parameters of the backup repeater, and compares the performance parameters with the numerical values in the preset priority to determine the performance parameters of the backup repeater. The data structure may be a linked list or an array, and the specific form of the data structure is not limited in the embodiments of the present invention.

When the processing unit utilization rate is C, the memory utilization rate is M, the number of running backup jobs is J, and the input/output load information is IO, the main server calculates a weighted sum of the processing unit utilization rate, the memory utilization rate, the input/output load information, and the number of running backup jobs of the backup server, and obtains a priority L of the backup relay, which may be:

L＝b1*C+b2*W+b3*D+b4*IO (1)

in the formula (1), b1, b2, b3 and b4 represent weights of C, M, J and IO in calculating priority, respectively, and b1+ b2+ b3+ b4 is equal to 1. The specific value of bi (i ═ 1, 2, 3, 4) can be set or recommended according to the operation condition of the server. For example, b1 is 0.3, b2 is 0.3, b3 is 0.2, and b4 is 0.2.

For example, in an internet of things, there are 4 repeaters at a node, namely, repeater 1, repeater 2, repeater 3 and repeater 4, where repeater 3 is a first repeater, the priorities of repeater 1, repeater 2 and repeater 4 are calculated according to the above formula (1), and if b1 is 0.4, b2 is 0.3 and b3 is 0.3, so that the priority of repeater 1 is 89, the priority of repeater 2 is 75 and the priority of repeater 4 is 67, the repeater 1 performs backup first, the repeater 2 performs backup after the backup is completed, and the repeater 4 performs backup after the backup is completed, thereby reducing the operation load and network maintenance overhead of the internet of things network caused by simultaneous backup and improving the backup efficiency.

Step S102: and when the first repeater is detected to be out of order, acquiring the priority of the backup repeater according to the performance parameters of the backup repeater.

In this embodiment, when the failure of the first repeater is detected, the priority of the backup repeater should be determined, and the backup should be performed according to the priority, thereby improving the backup efficiency.

For example, in an internet of things, there are 4 repeaters, namely, repeater 1, repeater 2, repeater 3 and repeater 4, at a node, where repeater 3 is the first repeater to communicate in the network, and the other three repeaters all serve as backup repeaters for repeater 3. In a certain communication process, the repeater 3 malfunctions, and at this time, the priorities of the repeater 1, the repeater 2, and the repeater 4 are calculated. Assuming that the calculation is performed according to the above equation (1), where b1 is 0.4, b2 is 0.3, and b3 is 0.3, the priority of the repeater 1 is 89, the priority of the repeater 2 is 75, and the priority of the repeater 4 is 67, these three calculation results are sorted, the repeater 1 with the highest priority is selected as the second repeater, and the repeater 2 and the repeater 4 are used as backup repeaters of the repeater 1. Therefore, normal communication of the repeater is guaranteed, and reliability of the Internet of things is improved.

Optionally, detecting the signal strength of the first repeater; when the signal intensity is smaller than a preset signal threshold, setting the waiting time of the received data as a second transmission duration; and judging whether the data sent by the Internet of things terminal is received in the second transmission time, if so, setting the data receiving waiting time as the first transmission time, and if not, confirming that the first repeater breaks down.

That is to say, when the signal strength is lower than the preset information threshold, whether the data sent by the terminal of the internet of things can be received or not is judged in the second transmission duration, and if the data can be received, the signal is weak, but the first repeater does not have a fault problem; if not, the first repeater is possibly in failure, namely, the first repeater is prevented from being in the future, and the failure resistance of the repeater of the Internet of things is improved. And the internet of things terminal connected with the first repeater can be distributed to the backup repeater, so that the waiting time for receiving data is prolonged, the burden of the first repeater is reduced, and the data transmission efficiency is improved.

Optionally, it is determined according to the size of the data traffic that when the data traffic of the first repeater is less than or equal to the preset traffic threshold, it is determined that the first repeater fails.

That is to say, when the data traffic is less than or equal to the preset traffic threshold, it indicates that the first repeater may malfunction, i.e. the first repeater is protected from the malfunction, and the malfunction resistance of the internet of things repeater is improved. And the internet of things terminal connected with the first repeater is allocated to the backup repeater in advance, so that the data receiving waiting time is prolonged, the burden of the first repeater is reduced, and the data transmission efficiency is improved.

For example, assuming that the preset traffic threshold is 60%, when the data traffic of the first relay is 50%, it is determined that the first relay fails, then the priority of the backup relay is obtained, and data backup is performed according to the priority.

Furthermore, the backup sequence is performed according to the priority level, so that the network bandwidth is not affected, and the network operation load is reduced. If the backup repeaters are 1-n in sequence, the backup repeater with the identifier 1 has the highest priority, and the backup repeater with the identifier n has the lowest priority. If the preset load threshold is 10M, performing backup of the second relay when the capacity of the cache data is 10M, and when the backup of the second relay is completed, performing backup of the third relay, and so on. Since the size of the capacity of the transmission data is not controllable, the second relay starts to backup as soon as the size of the capacity of the buffer data reaches a preset load threshold.

Step S103: and sequencing the priorities of the backup relays, and taking the third relay as the backup relay of the second relay when the priority of the third relay is lower than that of the second relay.

After the priorities of the backup relays are obtained, the backup relays are sorted according to the priorities, the priority of the second relay is higher than that of the third relay, the second relay takes over the work of the first relay, and the third relay serves as the backup relay of the second relay.

Step S104: and dividing the terminals of the internet of things connected with the first repeater into a first terminal set and a second terminal set.

Optionally, a data type of the internet of things terminal connected with the first repeater is obtained; and determining the terminals of the internet of things contained in the first terminal set and the second terminal set according to the data types. That is to say, the internet of things terminals connected to the first repeater are classified according to the data types, so that the parallel processing performance and the backup performance of the internet of things backup repeater system can be improved.

Step S105: and switching the Internet of things terminal in the first terminal set to the second repeater, and switching the Internet of things terminal in the second terminal set to the third repeater.

By adopting a multi-backup mode, the first backup repeater backs up the first repeater, so that when the first repeater breaks down, first cache data on the first repeater is not lost, a second repeater with the highest priority is selected to be connected with an Internet of things terminal of a first terminal set on the first repeater, a third repeater is used as a backup repeater of the second repeater to be connected with an Internet of things terminal of a second terminal set on the first repeater, cache data on the second repeater, and the second repeater is backed up while the first repeater is switched, so that the parallel processing performance and the backup performance of the Internet of things backup repeater system are improved.

Step S106: and sending the cache data of the second repeater to a third repeater.

Preferably, when the third repeater backs up the second cache data on the second repeater, since the first backup data on the first repeater has already been backed up before the failure of the first repeater, only the cached second cache data on the second repeater can be backed up, so that the repeated backup is avoided, and the backup time is saved. Specifically, the method comprises the following steps: the first backup repeater is also used for setting the backup state of the first cache data of the first repeater after the backup is finished as a backed-up state; the third repeater is also used for obtaining the backup state of the backup data of the second repeater and backing up the backup data of which the backup state is to be backed up to the third repeater.

Optionally, the radio frequency functions of the second repeater and the third repeater are turned on; acquiring a device identifier of an Internet of things terminal connected with a first repeater;

generating an equipment authentication code according to the equipment identification; sending the equipment authentication codes generated by the terminals of the internet of things in the first terminal set to the second repeater, and sending the equipment authentication codes generated by the terminals of the internet of things in the second terminal set to the third repeater; when the second repeater and the third repeater receive a connection request of the terminal of the Internet of things, judging whether the equipment identification of the terminal of the Internet of things initiating the connection request is matched with the equipment authentication code; and if the matching is successful, connecting with the terminal of the Internet of things.

In an optional embodiment, in order to improve the security of the backup data, the terminal of the internet of things should verify the device identifier of the terminal of the internet of things when being connected to the repeater, and when the device identifier of the terminal of the internet of things is successfully matched, the terminal of the internet of things initiating the connection request is received for connection, otherwise, if the matching fails, the radio frequency function of the backup repeater is closed.

The terminal of the Internet of things is a device which is connected with a sensing network layer and a transmission network layer in the Internet of things and used for acquiring data and sending the data to the network layer, and different device identifications are used for distinguishing different devices. For example, the device identifier of the terminal of the internet of things may be a MAC address of the terminal of the internet of things, where the MAC address is also called a physical address or a hardware address, and is used to define the location of the network device, the date of the time when the network device is accessed may be added with the terminal type, or a default name of the terminal of the internet of things by a computer program, or a combination of the terminal type and a number, or a name that a user stores the terminal of the internet of things. And switching the terminal of the internet of things on the first repeater to the second repeater, namely, the second repeater is only connected with the terminal of the internet of things on the first repeater which is successfully verified.

In one embodiment, after the first repeater fails, an equipment identifier of the internet of things terminal connected with the first repeater is acquired, where the equipment identifier is identification information which is embedded in an internet of things terminal equipment chip and 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 codes of the terminals of the internet of things connected with the first terminal set are sent to the second repeater, and the generated equipment authentication codes of the terminals of the internet of things connected with the second terminal set are sent to the third repeater. When the second repeater and the third repeater receive connection requests 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 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 repeater and the third repeater, 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 this embodiment, after the first repeater fails, MAC addresses of the second repeater and the third repeater are broadcast to the terminal of the internet of things, where the MAC addresses are also referred to as physical addresses or hardware addresses and are used to define the location of the network device, each repeater has a separate MAC address, and the terminal of the internet of things can initiate a connection request to the second repeater after receiving the MAC address of the second repeater.

It should be noted that the backup repeater can turn off the radio frequency function only as a storage device during backup, and turn on the radio frequency function only when establishing connection with the internet of things terminal of the first repeater, and the rest of the backup repeaters still turn off the radio frequency function, thereby reducing the occupation of system memory, saving power consumption and enhancing endurance time.

The implementation of the invention is described below in connection with a specific application scenario. In the application scenario, there are 3 repeaters at a node in the internet of things, which are a repeater J, a repeater K, and a repeater L, respectively, where the repeater J is a first repeater and performs communication in a network, and the other two repeaters are both used as backup repeaters of the repeater J, and only a storage function is turned on.

In a certain communication process, the relay J breaks down, the priority of the relay K is higher than that of the relay L according to the priority calculation results of the relay K and the relay L, the relay K is set as a second relay, and the relay L is set as a backup relay of the relay K.

Before the repeater J breaks down, the repeater J is connected with the Internet of things terminal 1, the Internet of things terminal 2 and the Internet of things terminal 3, and at the moment, the radio frequency functions of the repeater K and the repeater L are started.
