Background technique
In the Internet of Things network of magnanimity connection, a large amount of data pass back to cloud according to set pattern cycle
Server.Under the scheme uploaded immediately after traditional data sampling, the internet-of-things terminals of a large amount of identical operating modes may be
The same time initiates the connection to same server, to cause network/server congestion.
Traditional congestion avoidance schemes are generally basede on mature transport layer protocol, such as Transmission Control Protocol, prevent excessive data
It is injected into network.TCP controls congestion window by congestion detection, to obtain transmission throughput as high as possible, keeps away simultaneously
Exempt from network congestion.
However, transmission of the magnanimity without cooperation individual, although using the congestion control of transport layer, eventually because of service
The limited bandwidth in device end, so that the average throughput of single individual is lower.In addition, Network Packet Loss retransmits band under congested environment
The overhead come, so that internet-of-things terminal average transmission time will greatly increase.This to reduce internet-of-things terminal power consumption,
The power consumption of especially wireless terminal is extremely unfavorable.Lead to this is because the major power of wireless terminal is generally consumed in network
Letter, especially when the uplink that power amplifier is opened.

Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
As shown in Figure 1, the internet-of-things terminal of the embodiment of the present invention, comprising: micro controller unit 100, communication unit 200,
Signal acquisition unit 300, power down nonvolatile memory 400 and RTC interrupt awakening device 500.Specifically, micro controller unit
100 are bi-directionally connected with communication unit 200, signal acquisition unit 300 and power down nonvolatile memory 400, micro controller unit
100 input terminal is connect with the RTC output end for interrupting awakening device 500.
Communication unit 200 is for the information receiving and transmitting between internet-of-things terminal and server.Micro controller unit 100 is for bearing
Blame the work such as control, management, data transmit-receive and the data storage of internet-of-things terminal.Signal acquisition unit 300 is for acquiring sensing
The signal of device.In order to support the deep-sleep of low-power consumption, and sampling to separate with upload, RTC interrupts awakening device 500 and is used for
It is interrupted by RTC, the system in deep-sleep is waken up according to the time of setting.Power down nonvolatile memory 400 is used for
Storage operation field data, the order of preset value, current sampled data.In one embodiment of the invention, when secondary sampling
Data are stored in power down nonvolatile memory, such as FLASH memory.
The single work of internet-of-things terminal is divided into two stages:
In sample phase, internet-of-things terminal is not connected to external server, the beginning of this sampling of internet-of-things terminal
Time obtains after upper primary internet-of-things terminal connection server, or is derived and obtained according to fixed configurations.
In one embodiment of the invention, since data sampling depends on the characteristic of monitored target, thus it is sampled
Time is can to predefine, and be pre-configured with to internet-of-things terminal, including following two mode:
(1) sampling to rule: the disposable setting of configuration is arrived internet-of-things terminal, internet-of-things terminal by such as periodic sampling
RTC wakeup time is set according to configuration, periodic wakeup system is sampled；
(2) for irregular sampling: when internet-of-things terminal connects server, the sampling time next time is set dynamically,
RTC is arranged according to configuration in internet-of-things terminal, is sampled next time with waking up system.
When entering the data upload stage, internet-of-things terminal connects server, obtains and execute order, internet-of-things terminal
It being obtained after last time internet-of-things terminal connection server when this connection server time, equipment will upload data in this stage,
It obtains the sampling time next time and connects server time next time.
As shown in Fig. 2, the embodiment of the present invention also proposes a kind of Internet of Things Congestion Avoidance system based on server centered scheduling
System, comprising: internet-of-things terminal 1 and server 2.
Internet of Things connects next time sampling time of the server time then by server 2 according to internet-of-things terminal 1 next time
And to the prediction of Network status in future to determine, and it is configured in the connection of this Internet of Things.Due to server 2 possess it is whole
The state of a Internet of Things, such as total number of terminals, the sampling configuration etc. of each terminal, therefore can relatively accurately dispatch Internet of Things
The connection of network termination 1 and data upload, and reach and be supported on temporal equilibrium, avoid multiple internet-of-things terminals 1 as far as possible
Server 2 is connected simultaneously, while uploading data.
Internet-of-things terminal 1 in an inactive state, the low power consumpting state in deep sleep, the communication connection with server
It disconnects, to reduce power consumption as much as possible.Internet-of-things terminal 1 samples the configuration according to regulation, is sampled by RTC wake-up, so
After be stored in local power down nonvolatile memory.Scheduled configuration can be prolonged fixed configurations or short time
, when adjacent last time connects server, server dynamic setting.In the sampling process of data, internet-of-things terminal is not enabled
Communication.After the completion of sampling, internet-of-things terminal enters deep sleep state, avoids multiple internet-of-things terminals while uploading；Work as system
Reach preset data uplink time, the RTC of internet-of-things terminal interrupts awakening device and wakes up whole system again, carries out data
Upload, while obtaining during communication the time that data acquisition time and data next time upload.Weight is not stopped so
Go down again, as shown in Figure 3.
With reference to Fig. 3, in server end, sampling time and real-time demand of the server 2 according to single terminal, as far as possible
The upload of even ground dispatch terminal, to achieve the purpose that smoothing bandwidth.The present invention is random plus one on the basis of the sampling time
Time quantum regard its data upload time, it may be assumed that
tt(n)=ts(n)+Δ(n)
Wherein, ttIt (n) is some terminal n-th data uplink time, tsIt (n) is the n-th data sampling time of terminal,
Δ (n) is a stochastic variable.Wherein tsIt (n) is usually that user is pre-set.
It should be noted that aforesaid way is that for exemplary purposes, can also reach flat using other modes
The wide purpose of slide strips, details are not described herein.
Internet-of-things terminal according to an embodiment of the present invention and the Internet of Things Congestion Avoidance system dispatched based on server centered,
Using will sample the scheme isolated with upload, and the sampling time of single internet-of-things terminal and uplink time pass through server system
One scheduling.In such a way that this concentration cooperates, from macroscopically avoiding multiple terminals while uploading, to improve upload as far as possible
Success rate, shorten the time of network communication, to save the power consumption of single terminal and entire sensor network as far as possible.
