In one embodiment, data wireless acquisition module 3 includes single aggregation node, four relay nodes and multiple biographies Sensor node, the aggregation node are deployed in the center in the data collection zone domain of setting, and four relay nodes are set to number According to the different location in pickup area, and four relay nodes are identical as the distance between aggregation node, the multiple sensor Node needs to be deployed in the data collection zone domain according to actual monitoring;Sensor node is responsible for acquiring human health testing number One of relay node is sent to according to and by human health detection data, and relay node is by received human health detection data Single-hop is sent to aggregation node, and aggregation node converges received human health detection data and is sent to block chain memory module 2.
In one embodiment, sensor node model use Boolean sense model, sensor node the perception radius isomery, The perception radius of any sensor node is in [Hmin, Hmax] in range, wherein HmaxAnd HminIt is divided into sensor node the perception radius Bound;After multiple sensor nodes are needed to be deployed in the data collection zone domain according to actual monitoring, data are adopted Collection region is averagely divided into multiple rectangular net regions, is that the distribution monitoring of each net region is important according to monitoring requirements intensity Grade, the monitoring important level include rudimentary important, intermediate important and advanced important, the rudimentary important corresponding theory of setting Coverage density is 0.8, and the important corresponding theoretical coverage density of middle rank is 1.0, and advanced important corresponding theoretical coverage density is 1.2, calculating each net region is the sensor node quantity for meeting theoretical coverage density and needing to dispose, if NiIndicate i-th A net region is the sensor node quantity for meeting theoretical coverage density and needing to dispose, reality in i-th of net region The sensor node quantity that border has been disposed is Ni0If Ni0< Ni, then N is disposed in addition in i-th of net regioni-Ni0It is a Sensor node;Wherein, NiCalculation formula are as follows:
In formula, σiFor the theoretical coverage density that i-th of net region is correspondingly arranged, DiFor i-th of net region Size;Int is bracket function.
It, will after multiple sensor nodes are needed to be deployed in the data collection zone domain by the present embodiment according to actual monitoring Data collection zone domain is averagely divided into multiple rectangular net regions, and is the setting of each net region based on monitoring requirements intensity Corresponding theoretical coverage density, and the sensor node quantity that net region should be arranged is calculated according to theoretical coverage density, When the sensor node quantity of actual deployment is less than the sensor node quantity that be arranged, continue to increase sensor node.
The present embodiment enables to the sensor node deployment in each net region that can reach certain network to cover Lid density has ensured monitoring requirements, and the mode relative to random placement sensor node, has optimized network topology structure, into And promote the Monitoring Performance of wireless sensor network.
In one embodiment, after completing sensor node deployment, by the data collection zone domain random division set as r Virtual grid region, and make each relay node in different virtual grid regions;In the virtual net for not including relay node Lattice choose cluster head in region;Cluster head is responsible for the human health inspection of each sensor node acquisition in virtual grid region where collecting The human health detection data of collection is sent to apart from nearest relay node by measured data, each cluster head;It is saved comprising relaying In the virtual grid region of point, each sensor node is by human health detection data collected by directly transmitting or multi-hop The form of transmission is sent to corresponding relay node.
The present embodiment carries out human health inspection in the virtual grid region for not including relay node by way of sub-clustering The collection of measured data, and the entirety of network is advantageously reduced without a group cluster in the virtual grid region comprising relay node Energy consumption, while unnecessary sub-clustering is avoided, save sub-clustering energy consumption, the life cycle of effective prolonging wireless sensor network.
In one embodiment, the division number r in virtual grid region is determined according to the following formula:
In formula, D is the area in the data collection zone domain, LoFor the distance of relay node to aggregation node, int is to be rounded Function.
Actual conditions of the present embodiment based on data collection zone domain devise data collection zone domain and are divided into virtual grid area The calculation formula of the number in domain determines the number in virtual grid region according to the calculation formula, relative to the mode set at random, The number for optimizing sub-clustering is conducive to the energy consumption for saving net inner sensor node, and then reduces adopting for human health detection data Collect cost.
In one embodiment, cluster head is chosen in the virtual grid region for not including relay node, comprising:
(1) position of centre of gravity in virtual grid region is calculated:
In formula, VbIndicate that the position of centre of gravity of virtual grid region b, x (c) indicate c-th of biography in the virtual grid region b The abscissa of sensor node position, y (c) are the ordinate of c-th of sensor node position, wherein with convergence Node is coordinate origin, nbThe sensor node number having for the virtual grid region b;
(2) probability that each sensor node in virtual grid region serves as cluster head, and the maximum sensing of select probability are calculated Cluster head of the device node as the virtual grid region:
In formula, QbcThe probability of cluster head is served as c-th of sensor node in the b of virtual grid region,It is described c-th Sensor node and position of centre of gravity VbDistance,For u-th of sensor node and position of centre of gravity V in the b of virtual grid regionb Distance;For the minimum range of c-th of sensor node and relay node,For u-th of sensor section The minimum range of point and relay node, p1、p2For the weight coefficient and p of setting1> p2
The present embodiment calculates each virtual net by the way that data collection zone domain is averagely divided into multiple virtual grid regions The position of centre of gravity in lattice region.The present embodiment proposes the calculating that each sensor node in virtual grid region serves as the probability of cluster head Formula, in the calculation formula, the sensor node tool closer apart from place virtual grid regional barycenter position and relay node There is bigger probability to serve as the cluster head in the virtual grid region.The present embodiment select probability from each virtual grid region is maximum Sensor node as cluster head, on the one hand can guarantee that cluster head is evenly distributed in as far as possible in entire data collection zone domain, separately On the one hand it is able to ascend global optimum's performance of sub-clustering result, saves the energy that cluster head collects and transmits human body health detection data Consumption improves the stability that cluster head carries out human health detection data collection work.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected The limitation of range is protected, although explaining in detail referring to preferred embodiment to the present invention, those skilled in the art are answered Work as understanding, it can be with modification or equivalent replacement of the technical solution of the present invention are made, without departing from the reality of technical solution of the present invention Matter and range.
