Fig. 1 shows a kind of flow diagram of dual-mode communications network channel balancing method provided in an embodiment of the present invention.
The dual-mode communications network channel balancing method is applied to the dual-mode communications network wireless based on power wire broadband carrier and micropower,
The dual-mode communications network includes a central node and multiple child nodes, and the central node and the child node support electric power
Line bandwidth carrier and the wireless two kinds of communication modes of micropower.
In the present embodiment, the power wire broadband carrier network for power line narrow band carrier network, network
Faster, communication environments are more stable for access speed, and the data rate that channel can carry is higher.
The micropower wireless network is a kind of self-organizing network, and under certain condition, node is more, selectable routing
Path is more, and network reliability is higher.
Due to each network structure of dual-mode communications network and the difference of communication mode, which is hetero-com-munication
Network.
During carrying out network communication, the geographical location of central node and child node is relatively fixed, will not arbitrarily become
The case where moving, and be limited to geographical location, directly cannot carrying out network communication with central node there are child node.For this kind of son
Node needs to connect with other one or more child nodes to realize the communication connection between the child node and central node.
Due to being influenced by geographical environment, as part of nodes is in the underground of building in dual-mode communications network
Room by power wire broadband carrier communication is feasible between the part of nodes, but micropower by multistage wirelessly due to being routed
And the influence of signal penetrability causes traffic rate too low, is unable to satisfy the actual demand of business data transmission, then the part
It can be communicated by the communication mode of power wire broadband carrier between node；When the difficulty that can be arbitrarily routed between communication node
Spend bigger, if node is in the both sides in river, the difficulty and expense of wiring are especially big, then can be between the part of nodes
It is communicated by micro power radio communication mode；When can be communicated by power wire broadband carrier between two nodes,

Wave is communicated；Dotted line indicates micropower wireless channel, i.e., leads between two nodes that can arbitrarily communicate in dual-mode communications network
Micropower is crossed wirelessly to be communicated.
The child node can be communication equipment, measuring equipment etc..
For example, in power consumer electricity consumption information acquisition technique field, the use that is used by various measuring equipment metering users
The data such as electricity, water consumption and gas consumption.Data collection facility is considered as the central node in dual-mode communications network, each metering
Equipment is considered as dual-mode communications network child nodes, can lead between central node and child node, between child node and child node
Cross power wire broadband carrier or micropower wirelessly be attached, central node collects the various of each child node record
Data.By the identical messaging parameter of communication quality of two kinds of communication channels between two nodes that can arbitrarily communicate and uniformly
Measurement standard be described, it is logical according to routing algorithm for all child nodes that cannot be communicated with central node
Relay node is crossed to be communicated with central node, if child node B12 cannot be communicated directly with central node A, can pass through by
The data to be transmitted are sent to relay node B2, and data are forwarded to central node A by relay node B2, appoint in the routing
The optimal channel of communication quality may be selected between two nodes that meaning can communicate to be communicated, entire dual-mode communications network is improved
Communicate success rate.
The dual-mode communications network channel balancing method includes：
Step S110 obtains the power wire broadband carrier between two nodes that can arbitrarily communicate in the dual-mode communications network
The property parameters of channel and the property parameters of micropower wireless channel.
The property parameters of the power wire broadband carrier channel include signal effective power, noise effective power, signal electricity
The virtual value of pressure, transmission rate, sends message number, the number for being properly received message, channel quality at the virtual value of noise voltage
Deng.
The property parameters of the micropower wireless channel include signal strength, transmission rate, send message number, successfully connect
Number, the channel quality etc. of receiving text.
Step S120, according to the power wire broadband carrier channel and the property parameters of the micropower wireless channel
Calculate the messaging parameter of respective channels.
The messaging parameter includes communication success rate, load transmission rate and channel quality etc..
The communication success rate can carry out assessment acquisition in physical layer.
For example, being commented in power wire broadband carrier channel by measuring signal-to-noise ratio or the received signal strength of the channel
Estimate the communication success rate of the channel.
Signal-to-noise ratio is bigger, and the noise being mixed in signal is smaller, and signal demodulation success rate is higher, the communication success rate of the channel
It is higher；Signal-to-noise ratio is smaller, and the noise being mixed in signal is bigger, and signal demodulation success rate is lower, and the communication success rate of the channel is got over
It is low.
Signal-to-noise ratio can be obtained by following formula：
SNR=10lg (Ps/Pn)
Wherein, SNR is signal-to-noise ratio, unit dB；Ps is the effective power of signal, unit W；Pn is the Effective power of noise
Rate, unit W.
Signal-to-noise ratio can also be obtained by following formula：
SNR=20lg (Vs/Vn)
Wherein, SNR is signal-to-noise ratio, unit dB；Vs is the virtual value of signal voltage, unit V；Vn is noise voltage
Virtual value, unit V.
RSSI (signal strength) is bigger, and signal-to-noise ratio is bigger, closer, the easier solution of signal of transmitter distance receiver distance
It adjusts, the communication success rate of the channel is higher；RSSI is smaller, and signal-to-noise ratio is smaller, and transmitter distance receiver distance is remoter, and signal is got over
It is not easy to demodulate, the communication success rate of the channel is lower.
In micropower wireless channel, the received signal strength (RSSI) by measuring the channel assesses the communication of the channel
Success rate.
RSSI (signal strength) is bigger, and signal-to-noise ratio is bigger, closer, the easier solution of signal of transmitter distance receiver distance
It adjusts, the communication success rate of the channel is higher；RSSI is smaller, and signal-to-noise ratio is smaller, and transmitter distance receiver distance is remoter, and signal is got over
It is not easy to demodulate, the communication success rate of the channel is lower.
The communication success rate can also by MAC (Media Access Control, media access control) layer into
Row statistics obtains.
In the MAC layer of power wire broadband carrier network or micropower wireless network, count two at preset time intervals
Packet sending and receiving information between node；The communication success rate of corresponding network is calculated according to the packet sending and receiving information.
The packet sending and receiving information may include the number etc. for sending message number and being properly received message.
In the present embodiment, communication success rate can be obtained by following formula：
Communicate success rate=successful reception message number/transmission message number
For example, in 1h, if being communicated between node P and node Q by electric power elder generation carrier wave.It is carried in the broadband over power line
In wave channel, node P sends 255 messages to node Q altogether, and node Q is properly received 243 messages sent by node P, then
The communication success rate of power wire broadband carrier channel between node P and node Q is 243/255；If between node P and node Q
It is wirelessly communicated by micropower.In the micropower wireless channel, node P sends 255 messages, node Q to node Q altogether
229 messages sent by node P are properly received, then the communication success of the micropower wireless channel between node P and node Q
Rate is 229/255.
In link layer, communication success rate can also be described by link-quality (LQI).
Indicate the energy and quality of reception data frame.Its size based on signal strength and the signal-to-noise ratio detected (SNR),
Be calculated by MAC (media access control) layer and be supplied to upper one layer, generally with have correctly received data frame
Probability is related.IEEE 802.15.4 standard defines link-quality:Indicate (LQI) metering is exactly received data packet
Intensity and/or quality.
When dual-mode communications network is initially set up, communication success rate can be obtained by assessing in physical layer, in dual mode communication
After the network operation is stablized, it can be counted by MAC layer and obtain communication success rate, communicate success rate in dual-mode communications network to increase
Accuracy.
Furthermore it is also possible to communication success rate be calculated every prefixed time interval, to obtain the real-time of dual-mode communications network
Success rate is communicated, the precision that channel is measured is increased.
In the present embodiment, when the load transmission rate is by load data length and the used transmission load data
Between ratio be described.
Wherein, the transmission load data institute includes using the time：Add MAC layer, physical layer frame head postamble, channel
The brings time overheads such as coding；The brings time overheads such as physical layer transmission addition is leading, synchronizes；Other and channel physical layer
The characteristic being closely related, such as two OFDM of power wire broadband carrier ((Orthogonal Frequency Division
Multiplexing orthogonal frequency division multiplexi) intersymbol insertion protection interval and protocol stack in other layers in available communication
Rate evaluation network delay etc..
For example, as shown in Fig. 2, if being communicated between node B1 and node B14 by power wire broadband carrier, in the electricity
In power line bandwidth carrier channel, node B1 sends the data message that length is 200 bytes to node B14, transmits 200 byte
Time used in data message is 3ms, then the load of the power wire broadband carrier channel between node B1 and node B14 passes
Defeated rate is (200/1024) kb/3ms ≈ 64kbps；If wirelessly being communicated between node B1 and node B14 by micropower,
In the micropower wireless channel, node B1 sends the data message that length is 200 bytes to node B14, transmits 200 byte
Data message used in the time be 6ms, then the load transmission of micropower wireless channel between node B1 and node B14
Rate is (200/1024) kb/6ms ≈ 32kbps.
In some other embodiments, the load transmission rate can also be calculate by the following formula：
S=1/T (log2N)
Wherein, T is symbol transmission rate, i.e. the he number of transmission each second；What N one pulse of expression can indicate has
Valid value state, is equivalent to system number.
In the present embodiment, the channel quality is described by CQI.
CQI is the information instruction of channel quality, represents the quality of present channel quality, value range 0~31.When CQI is 0
When, indicate that present channel quality is worst；When CQI is 31, indicate that present channel quality is best.General common CQI is 12~
24。
In some other embodiments, channel quality can also be described by other parameters.
Step 130, by the communication of the messaging parameter of the power wire broadband carrier channel and the micropower wireless channel
Parameter carries out default operation respectively and generates a corresponding channel estimation value.
Wherein, the default arithmetic operation includes：
Success rate, the load transmission rate and the channel quality ratio shared in channel measurement are communicated according to described
Weight assigns different weights for it；According to the weight to the communication success rate, the load transmission rate and the channel
Quality seeks weighted average.
For example, respective channels evaluation of estimate can be calculate by the following formula：
Channel estimation value=communication success rate × m%+ load transmission rate × n%+ channel quality × r%
Wherein, it is shared in channel measurement to respectively indicate communication success rate, load transmission rate and channel quality by m, n, r
Weight, m%+n%+r%=1.
For example, need to primarily guarantee to communicate success rate if when carrying out transmission data in dual-mode communications network, then communication at
Power specific gravity shared in channel measurement is maximum, and 70 weight can be assigned for it, and the load transmission rate is measured in channel
In shared specific gravity take second place, 20 weight is assigned for it, channel quality proportion in channel measurement is minimum, assigns for it
Give 10 weight.
As shown in Fig. 2, between node B1 and node B14, it is described to communicate successfully in power wire broadband carrier channel
Rate, the load transmission rate and the corresponding specific value of channel quality are：243/255,64 and 20, then, the electric power line width
Channel estimation value=243/255 × 70%+64 × 20%+20 × 10%=15.4671 with carrier channel.
In micropower wireless channel, the communication success rate, the load transmission rate and the corresponding tool of channel quality
Body numerical value is：229/255,32 and 21,.So, channel estimation value=229/255 × 70%+32 of the micropower wireless channel
× 20%+21 × 10%=9.1286.
After obtaining the channel estimation value between node B1 and node B14, in subsequent path selection process, two node
Between preferentially select communication quality best the i.e. power wire broadband carrier channel of channel communicated.
In entire dual-mode communications network, due to can be carried by broadband over power line between two nodes that can arbitrarily communicate
Wave or the wireless two kinds of communication modes of micropower are communicated, and can arbitrarily be led to by dual-mode communications network channel balancing method by all
Letter two nodes between (between such as node A and node B1, between node A and node B2, between node A and node B3, node
Between A and node B4, between node B1 and node B14, between node B1 and node B15 etc.) channel estimations of different channels
Value is calculated, and the channel of two types network is described with unified parameter, provides unification for subsequent Path selection
