For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or, optionally, Other steps or units inherent to these processes, methods, products or equipment. Moreover, the terms "first," "second," and "third," etc. are used to distinguish different objects, and are not intended to describe a particular order.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In order to solve the technical problem that the transmission data is lost and the network works abnormally when the relay fails, in one embodiment, a processing method of the fault repeater is proposed. Implementation of the method may rely on a computer program that can run on a von Neumann system-based computer device, which can be a repeater's driver manager or virtual device manager.

The network architecture of the Internet of Things shown in Figure 1 includes servers, gateways, M access points, N repeaters, and several IoT terminals. The access points are connected via Ethernet or 2G, 3G, 4G, etc. The gateway is connected, the repeater is connected with a plurality of IoT terminals and an access point, and the IoT terminal transmits the collected data through the repeater, and the data is exchanged through the access point and the gateway device uploading server.

And the computer system is based on a repeater subsystem, the repeater subsystem shown in FIG. 2 includes at least a first repeater, a second repeater, and a third repeater, wherein the backup of the first repeater The node includes at least the second repeater and the third repeater, and the first repeater and the backup repeater are repeaters at the same node, and have the same function, and can be connected as a repeater to the Internet of Things. And the backup repeater of the first repeater is used to back up the cached data of the first repeater. The backup repeater can be a working repeater or an idle repeater. It should be noted that in order to improve the anti-fault capability of the network, there may be more than two backup repeaters, and the cache data of the first repeater is simultaneously backed up to multiple backup repeaters.

Specifically, as shown in FIG. 3, a method for backing up an Internet of Things repeater includes:

Step S102: Acquire a backup repeater of the first repeater, and buffer the number of the first repeater. Backed up 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 can be a Wi-Fi signal amplifier. Presetting a backup repeater for the repeater in the Internet of Things network environment, obtaining a repeater in the repeater subsystem, obtaining the first repeater comprising at least a second repeater and a third repeater Repeater. Obtaining the backup repeater of the first repeater, and backing up the data cached on the first repeater to the backup repeater, that is, reading the stored data on the second repeater and the third repeater. Get the cache data of the first repeater to ensure that the data is not lost. The cached data on the first repeater includes data collected by the Internet of Things terminal, and also data sent by the server to the Internet of Things terminal.

Optionally, the real-time backup will increase the operational load and network maintenance overhead of the IoT network. Therefore, a load threshold can be set. When the capacity of the cached data is greater than or equal to the load threshold, the repeater subsystem backs up the load. Or set the backup interval and back up the cached data at regular intervals.

Specifically, when the size of the buffered data of the first repeater reaches a preset capacity threshold or when the time recorded by the timer reaches a preset backup interval, the buffering of the first repeater is performed. The step of backing up data to the backup repeater. Therefore, it is avoided that the backup failure cannot be made when the first repeater fails, and the backup fails, and the anti-fault capability is improved.

Step S104: When detecting that the first repeater fails, obtain the priority of the backup repeater according to the performance parameter of the backup repeater.

In this embodiment, when detecting that the first repeater sends a failure, the priority of the backup repeater should be determined, and the backup is performed according to the priority, thereby improving the backup efficiency. The performance parameters of the backup repeater include: processing unit utilization, memory utilization, load/output information for the input/output, and the number of backup jobs that are running. Specifically, the backup repeater may first establish a data structure including the foregoing four types of information, then collect load sampling information of the backup repeater itself, record the load sampling information into the established data structure, and then record through the local Ethernet. The load sampling information is sent to the processor in the Internet of Things for handling the fault; the processor performs weighting calculation according to the performance parameters of the backup repeater, and compares the values in the preset priority to determine the performance of the backup repeater. parameter. The data structure may be a linked list or an array. The specific form of the data structure is not limited in the embodiment of the present invention.

When the processing unit utilization is C, the memory utilization is M, the number of running backup jobs is J, and the input/output load information is IO, the primary server calculates the processing unit utilization, memory utilization, and input/ of the backup server. The weighted sum of the output load information and the number of backup jobs being run, obtained The priority L of the backup repeater can be:

L=F(C,W,D)=b1*C+b2*W+b3*D (1)

In equation (1), X1, X2, X3, and X4 represent the weights of C, M, J, and IO in calculating the priority, respectively, X1+X2+X3+X4=1. Among them, the specific value of Xi (i = 1, 2, 3, 4) can be set according to the operation of the server or the recommended settings. For example, set X1=0.3, X2=0.3, X3=0.2, and X4=0.2.

Optionally, the cached data of the first repeater is backed up according to the priority of the backup repeater, thereby improving backup efficiency. Specifically, when the size of the buffered data of the first repeater reaches a preset capacity threshold or when the time recorded by the timer reaches a preset backup interval, according to the priority of the backup repeater The cached data of the first repeater is backed up.

The method for determining the failure of the first repeater may be detecting the signal strength of the first repeater, determining according to the signal strength, or determining according to the actual time of receiving the data when the signal is weak, and exceeding the waiting time of the received data. The first cached data sent by the reported IoT terminal is considered to be faulty.

Optionally, detecting a signal strength of the first repeater; when the signal strength is less than a preset signal threshold, setting a received data waiting time to a second transmission duration; determining whether the second transmission duration is within the second transmission duration Receiving data sent by the Internet of Things terminal, if yes, setting the received data waiting time to the first transmission duration, and if not, confirming that the first relay is faulty.

That is to say, when the signal strength is lower than the preset information threshold, it is determined whether the data transmitted by the Internet of Things terminal can be received within the second transmission time period. If so, the signal indicates that the first repeater does not appear. Failure problem; if not, it indicates that the first repeater may be faulty, that is, prevent the problem before it occurs, and improve the anti-fault capability of the IoT repeater. The IoT terminal connected to the first repeater can be allocated to the backup repeater to extend the waiting time of receiving data, thereby reducing the burden of the first repeater and improving data transmission efficiency.

For example, suppose the preset signal threshold is 60%. When the signal strength of the first repeater is 50%, the receiving data waiting time is set to the second transmission time of 5 minutes. At the end of 5 minutes, the data is not transmitted. , the first repeater is considered to be faulty, the priority of the backup repeater is obtained, and data backup is performed according to the priority level.

Further, the order of the backups is performed according to the priority level, so that the network bandwidth is not affected, and the network operation load is reduced. It is assumed that the priority of the backup repeater is from the highest to the lowest in the order of the backup repeater. If the identifier of the backup repeater is 1 to n, the backup repeater with the identifier 1 has the highest priority. The backup repeater for n has the lowest priority. If the preset load threshold is 10M, the backup of the second repeater is performed when the capacity of the cached data is 10M, when the backup of the second repeater is completed, the third repeater is backed up, and so on. Since the capacity of the transmitted data is uncontrollable, the second repeater starts backing up as long as the capacity of the cached data reaches a preset load threshold.

As another example, if the preset backup interval is 5 minutes, the cached data on the first repeater is backed up every 5 minutes.

Step S106: Sort the priorities of the backup repeaters, and when the priority of the third repeater is lower than the priority of the second repeater, use the third repeater as A backup repeater of the second repeater.

After obtaining the priority of the backup repeater, the backup repeaters are sorted according to the priority level, and the second repeater has a higher priority than the third repeater, and the second repeater takes over the first The repeater works while the third repeater acts as a backup repeater for the second repeater.

Step S108: Switching the Internet of Things terminal connected to the first repeater to the second repeater, and transmitting the cached data of the second repeater to the third repeater.

In the dual backup mode, the second repeater and the third repeater back up the first repeater, so that when the first repeater fails, the cached data on the first repeater is not lost, and is selected. The second repeater with the highest priority performs the work of the first repeater, switching the IoT terminal connected to the first repeater to the second repeater, and using the third repeater as the second repeater The backup repeater caches the cached data on the second repeater, and backs up the second repeater while switching the first repeater, thereby improving the parallel processing performance of the backup repeater and improving the backup. The overall backup performance of the system.

Optionally, the radio frequency function of the second repeater is enabled, the device identifier of the Internet of Things terminal connected to the first repeater is obtained, a device authentication code is generated, and the generated device authentication code is sent. And the second repeater determines, when receiving the connection request of the Internet of Things terminal, whether the device identifier of the Internet of Things terminal that initiates the connection request matches the device authentication code If the matching is successful, the IoT terminal that receives the connection request is connected to find the data to be backed up of the IoT terminal that is not backed up for backup; if the matching fails, the radio function of the backup repeater is turned off. .

In an optional embodiment, in order to improve the security of the backup data, the IoT terminal should verify the device identifier of the IoT terminal when connecting the repeater. When the device identifier of the IoT terminal is successfully matched, And receiving the IoT terminal that initiates the connection request to connect.

The IoT terminal is a device that connects the sensing network layer and the transmission network layer in the Internet of Things to collect data and send data to the network layer. Different device identifiers are used to distinguish different devices. For example, the device identifier of the Internet of Things terminal may be the MAC address of the Internet of Things terminal, and the MAC address is also referred to as a physical address or a hardware address, and is used to define the location of the network device, and may also access the date of the network time plus the terminal type or The default naming of the Internet of Things terminal by the computer program may also be a combination of the terminal type and the number, or may be the name saved by the user to the Internet of Things terminal. The IoT terminal on the first repeater is switched to the second repeater, that is to say, the second repeater only connects the IoT terminal on the first repeater that is successfully verified.

In an embodiment, after the first repeater fails, the device identifier of the Internet of Things terminal connected to the first repeater is obtained, where the device identifier is defined in the IoT terminal device chip for distinguishing The identification information of other devices cannot be changed after the device leaves the factory, including the serial number of the manufacturer, the model number of the device, and the MAC address of the device. The device authentication code is generated according to the device identification information, that is, the information is converted into a character coded form, such as a specific format such as "serial number-model-MAC address", which is convenient for other devices to read. Thereafter, the generated device authentication code of the Internet of Things terminal connected to the first repeater is transmitted to the second repeater. When the second repeater receives the connection request of the Internet of Things terminal, acquires the device identifier of the Internet of Things terminal, reads the device information from the device, and matches the previously saved device authentication code, and identifies and saves the device identifier in the Internet of Things terminal. When the device authentication code is successfully matched, the IoT terminal can be connected for connection. By saving the device authentication code and directly connecting after determining that the matching is successful, it is possible to avoid the process of session information authentication and key pairing of the device when the IoT terminal initiates a connection request to the second relay device, thereby improving the Internet of Things. Communication efficiency.

It should be noted that the device identifier of the Internet of Things terminal and the saved device authentication code may be successfully combined, for example, the serial number, the model number, and the MAC address are all the same; or when only the serial numbers are the same, That is, it is determined that the device identifier matches the saved device authentication code successfully; or if only a certain percentage of the characters in the string match, the matching is considered successful. In this way, the workload of data processing can be reduced and efficiency can be improved.

In this embodiment, after the first repeater fails, the MAC address of the second repeater is broadcast to the Internet of Things terminal, and the MAC address is also referred to as a physical address or a hardware address, and is used to define the location of the network device. Each repeater has a separate MAC address, and the IoT terminal can initiate a connection request to the second repeater after receiving the MAC address of the second repeater.

The implementation process of the present invention is set forth below in conjunction with a specific application scenario. In this application scenario, there are three repeaters at one node in the Internet of Things, namely, a repeater J, a repeater K, and a repeater L, wherein the repeater J is the first repeater, Communication takes place in the network, and the other two repeaters are used as backup repeaters for repeater J, and only the storage function is enabled.

In a certain communication process, the repeater J fails. According to the priority calculation result of the repeater K and the repeater L, the priority of the repeater K is higher than that of the repeater L, and the repeater K is Set to the second repeater, set the repeater L to the backup repeater of repeater K.

Before the fault of the relay J occurs, the Internet of Things terminal 1 and the Internet of Things terminal 2 are connected to the repeater J. At this time, the radio frequency function of the repeater K is turned on. The device K obtains the device authentication codes of the Internet of Things terminal 1 and the Internet of Things terminal 2 as "001-A1070-00010010" and "011-BC79-00101100", respectively, and saves them. Thereafter, the repeater K broadcasts the MAC address "00-01-6C-06-A6-29" of the repeater K to the Internet of Things terminal 1 and the Internet of Things terminal 2.

After receiving the MAC address, the Internet of Things terminal 1 and the Internet of Things terminal 2 initiate a connection request to the repeater K according to the MAC address.

The device K obtains the device identification information of the Internet of Things terminal 1 and the Internet of Things terminal 2 as "001-A1070-00010010" and "011-BC79-00101100" according to the connection request of the Internet of Things terminal 1 and the Internet of Things terminal 2, respectively. Same as the previously saved device authentication code, it is determined that the matching is successful, and the connection of the Internet of Things terminal 1 and the Internet of Things terminal 2 is received. During the operation of the repeater K, the cached data is simultaneously hot-backed to the repeater L to ensure the reliability of the Internet of Things communication.

In an optional embodiment, when the third relay backs up the cached data on the second repeater, since the backup data on the first repeater has been backed up before the first repeater fails, only The data cached by the Internet of Things terminals on the second repeater is backed up to avoid duplicate backups and save backup time. Specifically, the backing up the cached data of the first repeater to the backup repeater further includes: setting a backup state of the cached data of the first repeater that is backed up to be backed up; After the third repeater is used as the backup repeater of the second repeater, acquiring a backup status of the backup data of the second repeater, and the backup status is the to-be-backed The backup data is backed up to the third repeater.

In an alternative embodiment, the backup repeater can turn off the radio function at the time of backup and only acts as a storage device, and when acting as the first repeater role, that is, mount the first repeater. When the IoT terminal migrates to the second repeater, the radio function is enabled, and the remaining backup repeaters still turn off the radio function, reducing system memory usage, saving power consumption, and enhancing battery life. Specifically, the backing up the cache data of the first repeater to the backup repeater further includes: turning off a radio frequency function of the backup repeater; the connecting to the first repeater The radio frequency function of the second repeater is turned on before the IoT terminal switches to the second repeater.

Generating a device authentication code according to the device identifier of the IoT terminal connected by the first repeater, and when the device authentication code matches the device authentication code of the second repeater, connecting with the second terminal, thereby improving the Internet of Things relay The security of the device; if and only when the data is transmitted, the RF function of the IoT terminal is turned on, thereby saving users and enhancing the endurance. The third repeater identifies the backup data on the second repeater, and only backs up the data to be backed up by the unreserved IoT terminal, thereby improving the backup efficiency.
