In one embodiment, Fig. 3 is middle voltage distribution networks structural schematic diagram under master-slave network of embodiment of the present invention mode, and Fig. 4 is
Power transmission of embodiment of the present invention ratio and reflection coefficient relation schematic diagram, as shown in figure 3, USFor main carrier terminal equipment information source voltage, ZSFor
Main carrier machine and Coupling device equivalent internal resistance, ISThe electric current of distribution, P are inputted for information sourceSDistribution power is inputted for information source；Heavy line
Respectively indicating length is l1、l2, characterisitic parameter Zc1, γ1And Zc2, γ2Power transmission line；Route l1First end current is I11、
I12, first and last end (node 1,2) voltage is U1、U2；Route l2First end current is I21、I22, end (node 3) voltage is U3；ZT1、

Power transmission ratio S of Fig. 3 interior joint 1 to node 2 are as follows:
Theoretical by power line transmission:
Wherein, ΓuFor node voltage reflection coefficient, ΓIFor node current reflection coefficient, γ is line propagation constant, l is
Line length.
In order to facilitate observation voltage reflection coefficient ΓuInfluence variation to power transmission level S, above formula is to ΓuDerivation obtains:
Wherein, a=e-2γlAnd a ∈ (0,1), Γu∈(-1,1).Known to: ΓuWhen > 0, function S monotone decreasing, ΓuWhen < 0,
Function S monotonic increase.In the case of Fig. 4 gives a constant (a=0.9), function S and ΓuRelationship.As shown in Figure 4 | Γu| more
Greatly, S is smaller, and the power attenuation between two nodes is bigger, i.e., | Γu| can between two node of indirect reaction power attenuation size.
By conclusions it is found that adjacent two lines route shape parameter difference is bigger, corresponding power attenuation difference
It is bigger, so that the voltage reflection coefficient modulus value of two route beginning nodes | Γu| difference is bigger namely node shatter value JS is got over
Greatly, cause the match complexity between adjacent two nodes bigger, and network shatter value WS is present node upstream every two adjacent segments
Node shatter value between point it is cumulative, indicate the power coordination degree-of-difficulty factor between all nodes of the node and its upstream.Therefore with WSi
Size determine the point of the area limit in network (relay node), if WSiLess than prescribed limits, then by i-node and upstream net
Network divides same impedance matching section into；If WSiGreater than prescribed limits, then i-node is not belonging to the impedance matching section of upstream network,
I-1 node is set as relay node, i-node divides the second impedance matching section using i-1 node as relay node into.Successively class
It pushes away, by a big complicated power distribution communication net, is divided into several small impedance matching sections.
Further, matching and coordination is carried out using particle swarm intelligence algorithm in each impedance matching section, with upstream from load
It is constraint condition that wave machine, which receives power to be greater than recognizable minimum threshold, and downstream receives power from carrier terminal equipment and is up to target letter
It counts, respectively from the impedance matching parameter of carrier terminal equipment in Optimized Matching network, completes the coordinated allocation of power between each communication node.

Under letter, power respectively is received from carrier terminal equipment as shown in fig. 6, before optimization in addition to 1 node from signal outlet, other nodes on backbone
Decay larger, has been more than that its signal can recognize minimum threshold, the power attenuation of node 6,7 has been even more than -60dB, has caused
Signal can not be identified；It is coordinated and optimized using optimization method of the invention, is splitted the network into first shown in Fig. 7
Two impedance matching sections, are then optimized in each section using particle swarm algorithm, optimization last two zones it is interior respectively from
Carrier terminal equipment reception power is as shown in Figure 8, Figure 9, the optimization inside division and section through impedance matching section, all node powers
