The above embodiment of the present invention is by the acquisition to building internal stress data and acceleration information, in conjunction with building settlement The acquisition of parameter, displacement parameter, gradient parameter, fracture parameters realizes the comprehensive monitoring of building situation, the included number of system According to analytic function, the analysis of building safety hidden danger can be carried out according to the data detected in real time.
In one embodiment, the transmission range of oneself is adjusted to maximum by sensor node when initial, if sensor section Point is less than the currently transmitted distance of sensor node to the distance of aggregation node, and sensor node is directly by the building knot of acquisition Structure health monitoring data are sent to aggregation node, and otherwise, sensor node sends the building structure health monitoring data of acquisition To next-hop node, building structure health monitoring data are sent to aggregation node in the form of through multi-hop transmission；Sensor Node regularly updates the transmission range of oneself according to the following formula:
In formula, Xi(s) transmission range updated for sensor node i s-th of period, XiIt (s-1) is sensor node i In the transmission range that the s-1 period updates, QiFor the current remaining of sensor node i, Qi0For the first of sensor node i Beginning energy, QminFor preset energy lower limit,For bracket function, expression pairIt is rounded, ρ is the preset attenuation coefficient based on energy, and the value range of ρ is [0.4,0.6].
The present embodiment sets the calculation formula of transmission range based on the energy of sensor node, is innovatively sensor The routing mode selection that node sends building structure health monitoring data gives preferable measurement standard, i.e. sensor node arrives The distance of aggregation node is less than the currently transmitted distance of sensor node, and the building structure of acquisition is directly good for by sensor node Health monitoring data are sent to aggregation node, and otherwise, the building structure health monitoring data of acquisition are sent to down by sensor node Building structure health monitoring data are sent to aggregation node in the form of through multi-hop transmission by one hop node.Sensor node Suitable routing mode is selected based on transmission range, sensor node is advantageously reduced and sends building structure health monitoring data Energy consumption avoids sensor node from failing because energy rapidly depletes, and ensures the stability routed in wireless sensor network.
In one embodiment, if neighbor node is the other sensors node in sensor node communication range, When network is initial, sensor node obtains information of neighbor nodes by information exchange, constructs neighbor node collection, and save from its neighbour Point, which is concentrated, to be selected relative to it apart from the closer hop neighbor node of aggregation node as both candidate nodes, for each both candidate nodes point With priority level, so that both candidate nodes are divided into level-one both candidate nodes, second level both candidate nodes；Sensor node selects next-hop section When point, request message first is sent to level-one both candidate nodes and starts timer, if receiving level-one both candidate nodes after timing Feedback information, then select level-one both candidate nodes corresponding to the feedback information being connected at first as next-hop node；In timing If the feedback information of level-one both candidate nodes is not received after, sensor node sends request message simultaneously to second level both candidate nodes Start timer and selects the feedback information being connected at first if receiving the feedback information of second level both candidate nodes after timing Corresponding second level both candidate nodes are as next-hop node, if not receiving the feedback letter of second level both candidate nodes after timing Breath, sensor node are selected apart from nearest both candidate nodes as next-hop node.
In the present embodiment sensor node using relative to its apart from the closer hop neighbor node of aggregation node as candidate Node constructs the candidate node set as next-hop node candidate, limits the routed path of sensor node to aggregation node Length and direction, ensured the one-way transmission of building structure health monitoring data.
Wherein, priority level is distributed for each both candidate nodes, comprising:
(1) weight of each both candidate nodes is calculated:
In formula, WijFor the weight of the both candidate nodes j of sensor node i, M (i, j) is sensor node i and the both candidate nodes The distance of j, M (i, d) are at a distance from d-th of both candidate nodes of sensor node i and its, and M (j, s) is both candidate nodes j and convergence The distance of node, M (d, s) are d-th of both candidate nodes at a distance from aggregation node, niFor candidate's section of sensor node i Point quantity, BiFor the neighbor node quantity of sensor node i, BjFor the neighbor node quantity of the both candidate nodes j, Bi∩BjFor The quantity for the common neighbor node that sensor node i and both candidate nodes j are possessed, r1、r2For preset impact factor, meet r1+ r2=1；a1、a2For preset weight coefficient, meet a1+a2=1；
(2) ifBoth candidate nodes j is classified as level-one both candidate nodes, ifIt will Both candidate nodes j is classified as second level both candidate nodes, wherein WidFor the weight of d-th of both candidate nodes of sensor node i.
The present embodiment innovatively sets the index of priority level, wherein according to the position of both candidate nodes and itself and biography The relevance of sensor node proposes the calculation formula for measuring the weight of priority level.Sensor node is each time according to weight Node is selected to distribute priority level, so that both candidate nodes are divided into level-one both candidate nodes, second level both candidate nodes, by both candidate nodes Grade classification is carried out, the efficiency of selection for improving next-hop node is conducive to, sensor node is first selected from level-one both candidate nodes Next-hop node is conducive to the both candidate nodes that selection relevance is less as far as possible, and shortens sensor node to aggregation node Routed path length, thus reduce building structure health monitoring data transmission energy consumption, further extend wireless sensor network The service life of network.
In one embodiment, the request message includes the energy and bandwidth information of sensor node, and both candidate nodes connect After receiving the request message, judge itself whether meet following forwarding condition, if satisfied, both candidate nodes are to the sensor node Send feedback message:
In formula, KjFor the building structure health monitoring data packet number in the cache list of both candidate nodes j, QTIt is preset Forward the energy consumption of a building structure health monitoring data packet, QjFor the current remaining of both candidate nodes j, Qj0For both candidate nodes The primary power of j, QminFor preset energy lower limit, HTFor it is preset be a building structure health monitoring data packet services institute The bandwidth of consumption, HjFor the current residual bandwidth of both candidate nodes j, Hj0For the initial bandwidth of both candidate nodes j, QiFor sensor node The current remaining of i, Qi0For the primary power of sensor node i, HiFor the preceding remaining bandwidth of sensor node i, Hi0To pass The initial bandwidth of sensor node i, e1、e2For preset weight factor, meet e1+e2=1, δ are preset tolerance coefficient, and δ's takes Being worth range is [0.4,0.6].
The game of surplus resources of the present embodiment based on both candidate nodes and sensor node innovatively sets forwarding item Part after both candidate nodes receive the request message, determines whether the sensing according to the forwarding condition itself whether is met Device node sends feedback message.The present embodiment makes have more enough resources to execute building structure health monitoring data forwarding times The both candidate nodes of business just have an opportunity to be chosen as next-hop node, this be conducive to improve building structure health monitoring data transmission can By property, while being beneficial to the resource of each both candidate nodes in equalising network.By voluntarily being judged whether under competition by both candidate nodes One hop node balances calculating relative to uniformly judging whether both candidate nodes meet the mode of forwarding condition by sensor node Expense, the further balanced energy consumption of each sensor node of network.
