In one embodiment, each sensor node builds wireless sensor network by self-organizing, and builds wireless
Sensor network uses clustering topology, will be distributed over the sensor node to build a bridge in structure monitoring region according to node
Geographical location is divided into N number of cluster, and each cluster selects a sensor node as cluster head, remaining sensor node saves for member
Point, wherein cluster head are used to collect the bridge dangerous position monitoring data of each member node acquisition in its cluster.
Preferably, each cluster selects a sensor node as cluster head, specifically includes：
(1) base station equipment 2 broadcasts beacon message, network inner sensor nodes records As-received into network with maximum power
The actual signal intensity of 2 beacon message of station equipment, the beacon message include being connect by each sensor node that base station equipment 2 is set
Receive the theory signal intensity of beacon message；
(2) network inner sensor node becomes candidate cluster head with the probability of initial setting up, and candidate cluster head calculates the excellent of itself
Choosing value, then broadcasted with maximum power oneself be cluster head message, if receiving another preferred value bigger in setting time
Candidate cluster head broadcast message, then abandon the competition of cluster head, otherwise oneself become cluster head；
Wherein, the calculation formula of the preferred value is：
In formula,Indicate sensor node SαPreferred value,For sensor node SαCurrent remaining,For
Sensor node SαPrimary power,For sensor node SαCommunication distance, D (Sα, O) and it is sensor node SαIt is set with base station
Standby 2 distance,For sensor node SαThe actual signal intensity of 2 beacon message of base station equipment is received,For by base station equipment 2
The sensor node S of settingαReceive the theory signal intensity of beacon message, λ1、λ2For the weight coefficient of setting, meet λ1+λ2=1；For the value function of setting, whenWhen,WhenWhen,
(3) the sensor node overseas broadcast for being elected as cluster head oneself is the message of cluster head, other sensors node according to
Signal strength sends addition message to determine to be added some cluster to cluster head.
The present embodiment proposes a kind of new cluster head election contest mechanism, and in the mechanism, network inner sensor node is initially to set
The probability set becomes candidate cluster head, then broadcasted with maximum power oneself be cluster head message, if being received in setting time another
The message of the candidate cluster head broadcast of an outer preferred value bigger, then abandon the competition of cluster head, otherwise oneself becomes cluster head.
In the prior art when carrying out the competition of candidate cluster head, usual means are directly maximum using current remaining
Candidate cluster head as cluster head, this mode is there is no considering ability of the cluster head in terms of communication stability, and cluster head is logical
Ability in terms of letter stability influences whether the quality of bridge dangerous position monitoring data transmission, such as cluster head is from base station equipment 2
When remoter, the probability that the bridge dangerous position monitoring data of cluster head collection are lost in transmission process is also bigger, and
The cost of time and energy also bigger.
And the present embodiment carries out the competition of candidate cluster head by preferred value size, and correspondingly define the calculating of preferred value
Formula.The calculation formula has considered the energy of sensor node, to the factor of 2 distance of base station equipment, and creatively root
The difference of the actual signal intensity and theory signal intensity that receive beacon message according to sensor node devises adding for distance
Weight coefficient so that preferred value can accurately more weigh ability of the sensor node in terms of communication stability.The present embodiment can
Integration capability more preferably cluster head is chosen, the stability and bridge dangerous position monitoring data to improve clustering topology pass
Defeated quality further saves the energy of transmission bridge dangerous position monitoring data, reduces the monitoring for the structural system that builds a bridge
Cost.
