Data fusion is carried out to cluster interior nodes again using DFACT algorithm in the step S3, if node goes out in-degree degree
For Deg, while remembering that Loop is the maximum value of data fusion cycle-index, and fusion results cluster head is each sensing node distribution one
A time delay MergeD distributes an a connection time delay ConnD and fusion time delay AggD within the MergeD time:
Wherein, the height for the Data Fusion Tree that algorithm generates in MAX_DEPTH cluster.
In the present embodiment, when node number under attack increases, Loop value is accordingly reduced, higher to obtain accuracy
Fusion results.
DFACT algorithm in the S3 uses sum function for data fusion function, then data fusion function y (t) are as follows:
Wherein, di(t) data that sensing node i is collected into t moment in cluster are indicated.
In the present embodiment, the hop count h value for the Congestion Level SPCC for mitigating network, the transmission of cluster internal segment point data is selected as 1,
In the MergeD period, by TAG algorithm construction data fusion balanced binary tree, data fusion is carried out to father node i in child node
When, write down the child node number deg of father node ii, node i distributes the memory headroom that size is 1bit and is used to record
The cycle-index loop of the data fusion of the node, after Data Fusion Tree construction complete, note loop is 1, logical in node connection
In the letter stage, to reduce the collision generated by data communication, the ConnD period is uniformly divided into tpPiece, most by Data Fusion Tree
Big height MAX_DEPTH determines that the number of the timeslice of distribution, node i distribute the height that 1b memory is used to memory node
depthi,
The timeslice t that is distributed in ConnD of sensing node first1It is interior, allow node degiIt is randomly choosed for 0 sensing node
Time is connected to its father node, and writes down degiFor the height depth of 0 nodeiIt is 0, the height of father node is then denoted as
1, until the node for allowing the height of node to be MAX_DEPTH is ganged up within the time of its distribution with cluster head, node is tested first
Demonstrate,prove the height depth of oneselfiWhether be less than MAX_DEPTH, when node height be MAX_DEPTH, that is, indicate the node be cluster
Head, without request send data, in Lifetime section, only need to receive data, within the AggD time, from bottom sensing node to
Father node carries out data fusion operation layer by layer, and final cluster head obtains the fusion results of all node datas, while leader cluster node will
The cycle-index loop of data fusion increases by 1, for the security risk for solving wireless network data transmission, adds to communication data
Close calculating, using random key distribution mechanism, to guarantee that security risk that cluster interior nodes occur does not influence in other clusters code key more
Newly, the consumption of node resource is reduced, each fasciation possesses K code key at a code key pond in pond, cluster interior nodes are from this code key
K code key is randomly selected in pond, by sharing code key, prevents communication data from maliciously being stolen, if loop value is equal to or more than
Loop is then updated the code key pond in the cluster.Simultaneously because the characteristics of balanced binary tree, when a certain node occur it is abnormal,
It such as cannot normally be connected to or maliciously be intercepted and captured, can all cause the variation of a certain subtree height of Data Fusion Tree, i.e. left and right subtree
Difference in height be greater than 1 when, regenerate partial equilibrium binary tree, and update code key pond.
In the present embodiment, by the way that the efficiency of condition monitoring can not only be improved to wireless sensor network node progress sub-clustering,
And accurate judgement can be made to the safe condition of monitoring device, node energy consumption is reduced, network lifecycle is extended, protects number
According to safety.

Optimal value is calculated using PSO algorithm in S2, it is assumed that different particles indicates different cluster structured, objective function results in population
Indicate the cluster structured performance, initializing m particle first is a population, finds out optimal solution, guarantees target function value
It minimizes, objective function is as follows:
Cost=β f1+(1-β)f2
Wherein, f1Indicate node compactness, d (ni, CHP, K) indicate node and cluster head relative distance, | CP, K| it is the cluster internal segment
The quantity of point, f2Indicate that the energy height of cluster head, β indicate the weight coefficient between the different factors.
8. the remote supervisory and control(ling) equipment that a kind of liquid manure integral type according to claim 5 is irrigated, it is characterised in that: the step
Data fusion is carried out to cluster interior nodes again using DFACT algorithm in S3, if the in-degree degree that goes out of node is Deg, while remembering Loop
For the maximum value of data fusion cycle-index, and fusion results cluster head is that each sensing node distributes a time delay MergeD,
An a connection time delay ConnD and fusion time delay AggD is distributed in the MergeD time:
Wherein, the height for the Data Fusion Tree that algorithm generates in MAX_DEPTH cluster.
9. the long-distance monitoring method that a kind of liquid manure integral type according to claim 8 is irrigated, it is characterised in that: in the S3
DFACT algorithm use sum function for data fusion function, then data fusion function y (t) are as follows:
Wherein, di(t) data that sensing node i is collected into t moment in cluster are indicated.
