To cause loss of transmitted data and the technical problem of network operation irregularity when solving relay failure, in an implementation
In example, spy proposes a kind of processing method of failed repeater.The realization of this method can be dependent on computer program, the computer
Program can run on the computer installation based on von Neumann system, and the computer program can be the driving tube of repeater
Manage program or virtual device manager.
The network architecture of Internet of Things as shown in Figure 1 includes server, gateway, M access point, N number of repeater and some
Individual internet-of-things terminal, access point are connected by latticed forms such as Ethernet or 2G, 3G, 4G with gateway, repeater and multiple things
Networked terminals are connected with access point, and the data of collection are transmitted by internet-of-things terminal by repeater, by access point and net
Close the exchange that equipment upload server carries out data.
And the computer system is based on repeater subsystem, repeater subsystem as shown in Figure 2 is comprised at least in first
After device, the second repeater and the 3rd repeater, wherein the backup node of the first repeater comprises at least the second repeater and the 3rd
Repeater, the first repeater and backup relays device are the repeater at same node, and its function phase is same, can be used as repeater
It is connected in Internet of Things, and the backup relays device of the first repeater is used to back up the data cached of the first repeater.Backup relays
Device can be the repeater or idle repeater to work.It should be noted that in order to improve the anti-event of network
Barrier ability, backup relays device can more than two, and the first repeater data cached while back up in multiple backup relays devices.
Specifically, as shown in figure 3, a kind of backup method of Internet of Things repeater, including：
Step S101：The backup relays device of the first repeater is obtained, data cached by the first repeater backs up to backup
Repeater.
Repeater is mainly used in strengthening the coverage of access point AP wireless signal, for example, repeater can be Wi-Fi
Signal amplifier.In advance to the repeater design backup relays device in Internet of Things network environment, obtain in repeater subsystem
Repeater obtains the first repeater and comprises at least two repeaters of the second repeater and the 3rd repeater.Obtain the first repeater
Backup relays device, by the data backup cached on the first repeater to backup relays device, that is to say, that read the second repeater and
Data storage on 3rd repeater can obtain the data cached of the first repeater, it is ensured that data are not lost.On first repeater
It is data cached include internet-of-things terminal collection data, the data also sent including server to internet-of-things terminal.
Optionally, when the data cached amount of capacity of the first repeater reaches preset capacity threshold value or timer record
Time when reaching default backup interval time, perform the data cached step for backing up to backup relays device of the first repeater
Suddenly.The situation of backup failure is caused to occur so as to avoid to be attached with backup relays device in the first relay failure,
Improve fault-resistant ability.
That is, when data cached capacity is more than or equal to load threshold, repeater subsystem is just carried out to it
Backup.Or backup interval time threshold value is set, and backed up at regular intervals to data cached, it is standby in real time so as to alleviate
The operating load and network operation expense of Internet of Things network caused by part, and avoid the first relay failure from causing loss of data.
Such as：If preset capacity threshold value is 10M, the second repeater is carried out when data cached amount of capacity is 10M
Backup；If default backup interval time is 5 minutes, often spends 5 minutes and data cached on the first repeater is backed up.
Further, when the data cached amount of capacity of the first repeater reaches preset capacity threshold value or timer record time
When reaching default backup interval time, the excellent of backup relays device is calculated according to the performance parameter of the backup relays device of the first repeater
First level；The data cached of the first repeater is backed up according to the priority of backup relays device.Backed up according to priority,
So as to improve backup efficiency.
The performance parameter of backup relays device includes：Processing unit utilization rate, memory usage, the load letter of input/output
The backup job number for ceasing and being currently running.Specifically, backup relays device can first establish the data knot for including above-mentioned four kinds of information
Structure, the load sample information of backup relays device itself is then gathered, load sample information recorded in the data structure of foundation；
The load sample information of record is sent into Internet of Things to the processor for being responsible for handling failure accident by local ethernet again；Place
Reason device is weighted according to the performance parameter of backup relays device, and it is standby that determination is compared with the numerical value in default priority
The performance parameter of part repeater.Wherein, the data structure can be chained list or array etc., and the embodiment of the present invention is to data structure
Concrete form is not construed as limiting.
When processing unit utilization rate is C, memory usage M, the backup job number that is currently running are J, input/output
When load information is IO, master server calculates the processing unit utilization rate of backup server, memory usage, input/output
The weighted sum of load information and the backup job number being currently running, obtaining the priority L of backup relays device can be：
L=b1*C+b2*W+b3*D+b4*IO (1)
In formula (1), b1, b2, b3 and b4 represent C, M, J and IO and are calculating the weight of priority, b1+b2+b3+b4=respectively
1.Wherein, bi (i=1,2,3,4) specific value can be set or using recommended setting according to the running situation of server.For example,
B1=0.3, b2=0.3, b3=0.2, b4=0.2 are set.
For example, in an Internet of Things, there is 4 repeaters at a node, respectively repeater 1, repeater 2, in
After device 3 and repeater 4, wherein repeater 3 is the first repeater, according to above-mentioned formula (1) calculate repeater 1, repeater 2 and in
After the priority of device 4, it is assumed that b1=0.4, b2=0.3, b3=0.3, it is 89 so as to obtain the priority of repeater 1, repeater 2
Priority be 75, the priority of repeater 4 is 67, then repeater 1 is first backed up, and repeater 2 is carried out standby after the completion of backup
Part, repeater 4 is backed up after the completion of backup, the operating load of Internet of Things network caused by alleviating while backing up and network dimension
Expense is protected, improves backup efficiency.
Step S102：When detecting the first repeaters fail, obtained according to the performance parameter of backup relays device standby
The priority of part repeater.
In the present embodiment, when detecting the first repeaters fail, it should be determined that the priority of backup relays device,
Backed up according to priority, so as to improve backup efficiency.
For example, in an Internet of Things, there is 4 repeaters at a node, respectively repeater 1, repeater 2, in
After device 3 and repeater 4, wherein repeater 3 is the first repeater, is communicated in a network, other three repeater all conducts
The backup relays device of repeater 3 uses.In certain communication process once, repeater 3 breaks down, now calculate repeater 1,
The priority of repeater 2 and repeater 4.Assuming that calculated according to above-mentioned formula (1), wherein b1=0.4, b2=0.3, b3=
0.3, it is 89 so as to obtain the priority of repeater 1, the priority of repeater 2 is 75, and the priority of repeater 4 is 67, to this
Three result of calculations are ranked up, and select the repeater 1 of highest priority to be used as the second repeater, by repeater 2 and repeater 4
Backup relays device as repeater 1.So as to ensure repeater proper communication, the reliability of Internet of Things is improved.
Optionally, the signal intensity of the first repeater is detected；When signal intensity is less than preset signals threshold value, number will be received
The second transmission duration is arranged to according to the stand-by period；Judge the number that internet-of-things terminal is sent whether is received in the second transmission duration
According to if so, the first transmission duration is arranged to by data latency time is received, if it is not, then confirming the first repeaters fail.
That is, when signal intensity is less than presupposed information threshold value, judge whether to receive in the second transmission duration
The data sent to internet-of-things terminal, if can, though illustrating that signal is weak, the first repeater does not have failure problem；If no
Can, then illustrate that the first repeater may break down, that is, prevent trouble before it happens, improve the fault-resistant ability of Internet of Things repeater.And
The internet-of-things terminal that first repeater connects can be distributed to backup relays device, extend and receive data latency time, so as to reduce
The burden of first repeater, improve data transmission efficiency.
Optionally, judged according to data traffic size, when the data traffic of the first repeater is less than or equal to preset flow
During threshold value, the first repeaters fail is determined.
That is, when data traffic is less than or equal to preset flow threshold value, then illustrate that the first repeater may occur
Failure, that is, prevent trouble before it happens, improve the fault-resistant ability of Internet of Things repeater.And the Internet of Things in advance connecting the first repeater
Terminal distribution gives backup relays device, extends and receives data latency time, so as to reduce the burden of the first repeater, improves data and passes
Defeated efficiency.
As an example it is assumed that preset flow threshold value is 60%, when the data traffic of the first repeater is 50%, it is determined that
First relay failure, the priority of backup relays device is then obtained, data backup is carried out according to priority height.
Further, the order of backup is carried out according to the height of priority, so as to not influence network bandwidth, reduces network fortune
Row load.It is assumed that according to backup relays device mark order priority from small to large from high to low, if the mark of backup relays device
Know for 1~n when, that is, be identified as 1 backup relays device highest priority, the backup relays device priority for being identified as n is minimum.It is if pre-
If load threshold is 10M, then the backup of the second repeater is carried out when data cached amount of capacity is 10M, when the second relaying
Device backup is completed, the backup of the 3rd repeater, the like.Because the amount of capacity for transmitting data is uncontrollable, as long as so caching
The second repeater begins to back up when the amount of capacity of data reaches default load threshold.
Step S103：The priority of backup relays device is ranked up, is less than in the priority of the 3rd repeater in second
When the priority of device, the backup relays device using the 3rd repeater as the second repeater.
After the priority of backup relays device is obtained, backup relays device is ranked up according to the height of priority,
The priority of second repeater is higher than the 3rd repeater, then the second repeater takes over the work of the first repeater, and the 3rd relays
Backup relays device of the device as the second repeater.
Step S104：The internet-of-things terminal being connected with the first repeater is divided into first terminal set and second terminal collection
Close.
Optionally, the data type for the internet-of-things terminal being connected with the first repeater is obtained；Is determined according to data type
The internet-of-things terminal included in one terminal set and second terminal set.That is, according to data type by the first repeater
The internet-of-things terminal of upper connection is classified, and can improve parallel processing performance and the backup of Internet of Things backup relays device system
Energy.
Step S105：Internet-of-things terminal in first terminal set is switched into the second repeater, by second terminal set
In internet-of-things terminal switch to the 3rd repeater.
By the way of backing up, the first backup relays device is backed up to the first repeater more so that the first repeater is sent out
During raw failure, on the first repeater first it is data cached do not lose, and choose the second repeater of highest priority to connect the
The internet-of-things terminal of first terminal set on one repeater, connect the 3rd repeater as the backup relays device of the second repeater
The internet-of-things terminal of the second terminal set on the first repeater is connect, caches data cached on the second repeater, switching first
The second repeater is backed up while repeater, so as to improve the parallel processing performance of Internet of Things backup relays device system
And backup performance.
Step S106：By the data cached transmission of the second repeater to the 3rd repeater.
Preferably, the 3rd repeater back up the second repeater on second it is data cached when, due on the first repeater
First Backup Data has backed up completion before the first relay failure, can be only to cached second on the second repeater
It is data cached to be backed up, avoid repeating to back up, save BACKUP TIME.Specifically：First backup relays device is additionally operable to back up
First data cached Status of Backups of the first repeater completed is arranged to back up；3rd repeater is additionally operable to acquisition second
The Status of Backups of the Backup Data of repeater, it is that Backup Data to be backed up backs up to the 3rd repeater by Status of Backups.
Optionally, the radio-frequency enabled of the second repeater and the 3rd repeater is opened；Obtain the thing being connected with the first repeater
The device identification of networked terminals；
Device authentication coding is generated according to device identification；The equipment that internet-of-things terminal in first terminal set generates is recognized
Card coding is sent to the second repeater, and the device authentication coding that the internet-of-things terminal in second terminal set is generated is sent to the
Three repeaters；Second repeater and the 3rd repeater judge that initiating connection asks when receiving the connection request of internet-of-things terminal
The device identification for the internet-of-things terminal asked whether with device authentication codes match；If the match is successful, carried out with the internet-of-things terminal
Connection.
In an alternative embodiment, in order to improve the security of Backup Data, internet-of-things terminal is in this connection when device
The device identification of internet-of-things terminal should be verified, when the match is successful for the device identification of internet-of-things terminal, then receives and initiates connection
The internet-of-things terminal of request is attached, if otherwise it fails to match, closes the radio-frequency enabled of backup relays device.
Internet-of-things terminal is that Sensor Network network layers and transport network layer are connected in Internet of Things, realizes gathered data and to Internet
The equipment for sending data, different device identifications are used for the different equipment of distinctive mark.For example, the device identification of internet-of-things terminal
Can be the MAC Address of internet-of-things terminal, MAC Address is also known as physical address or hardware address, for defining the network equipment
Position, the date of network time can also be accessed plus the terminal type life that either computer program is given tacit consent to internet-of-things terminal
Name or terminal type addend combinatorics on words, can also be the title that user saves as to internet-of-things terminal.By in first
The second repeater is switched to after the internet-of-things terminal on device, that is to say, that successful first relaying of the second repeater connectivity verification
