Embodiment
The invention will be further described with the following Examples.
A kind of transformer on-line intelligence monitoring system provided referring to Fig. 1, Fig. 2, the present embodiment, including based on wireless biography Transformer sensor monitoring module 1, Surveillance center 2 and the intelligent terminal 3 of sensor network, described transformer sensor monitoring mould Block 1 is used to gather transformer status data and send the transformer status data collection of collection to Surveillance center 2；It is described Surveillance center 2 data analysis and process is carried out to transformer status data, the health status of transformer is judged in time；Institute The intelligent terminal 3 stated obtains the health status of transformer status data and transformer by access monitoring center 2.
Preferably, the transformer status data includes displacement, acceleration, strain, degree of corrosion.
Preferably, the Surveillance center 2 is good for including data memory module 10, Data Analysis Services module 20, transformer Health state display module 30.
Preferably, described transformer sensor monitoring module 1 includes multiple status monitoring sensor nodes and cluster head is passed Sensor node, status monitoring sensor node is used to gather transformer status data and by the transformer status data of collection Send to cluster head sensor node, cluster head sensor node collects the transformer shape of all status monitoring sensor nodes in cluster State data, and the transformer status data of collection is passed into Surveillance center 2.
Preferably, the status monitoring sensor node is arranged on transformer.
The above embodiment of the present invention employing wireless sensor network realizes the wireless monitor of transformer state, system tool Have the advantages that laying is convenient, monitoring is comprehensive, it is efficient to communicate.
Preferably, if status monitoring sensor node is a hop neighbor node of cluster head sensor node, it directly will Transformer status data is sent to cluster head sensor node；If status monitoring sensor node is non-for cluster head sensor node One hop neighbor node, it selects relay forwarding node auxiliary to send transformer status data to cluster head biography from its neighbor node Sensor node.
Preferably, status monitoring sensor node selects the auxiliary transmission power transformation of relay forwarding node to set from its neighbor node It is specific to perform during standby status data to cluster head sensor node：
(1) each neighbor node for calculating status monitoring sensor node serves as the ability value of relay forwarding node：
In formula, SijRepresent status monitoring sensor node SiJ-th of neighbor node, Q (Sij) represent SijRelaying is served as to turn The ability value of node is sent out,For link Si,SijBetween status monitoring sensor node SiReceived signal strength indicator value, Represent link Si,SijBetween SijReceived signal strength indicator value, d (Sij,Si) represent Si,SijBetween Euclidean distance, niFor Status monitoring sensor node SiComprising neighbor node number, α, β for setting weight coefficient；
(2) each neighbor node is arranged according to the descending order of energy value, forms alternative relay forwarding node List, status monitoring sensor node selected from its alternative relay forwarding node listing preferred value it is maximum be used as relay forwarding Node, and then transformer status data is sent to cluster head sensor node by relay forwarding node auxiliary.
This preferred embodiment defines the determination strategy of relay forwarding node, so as to realize that fast and effectively optimal relaying turns Node selection is sent out, method is simple and convenient, in selecting when forward node, it is contemplated that the bi-directional link quality of neighbor node and away from From factor so that the relay forwarding node selected being capable of relatively accurately auxiliary transmission transformer status data, and can The load that reduction status monitoring sensor node is born in itself, saves status monitoring sensor node and is transmitted to relay forwarding node The energy consumption of transformer status data.
Preferably, when the relay forwarding node of selection, which meets following renewal, judges formula, status monitoring sensor node The replacement of the preferred value maximum relay forwarding node is selected in remaining neighbor node in its alternative relay forwarding node listing：
In formula, SabRepresent relay forwarding node SaB-th of neighbor node,S is represented respectivelyabIt is current surplus Complementary energy, primary power,For link Sa,SabBetween SaReceived signal strength indicator value,For link Sa,SabBetween Sab Received signal strength indicator value, SacRepresent relay forwarding node SaRemove SabC-th outer of neighbor node,For link Sa, SacBetween SaReceived signal strength indicator value,For link Sa,SacBetween SacReceived signal strength indicator value, naFor in After forward node SaNeighbor node number, EtFor the energy threshold of setting.
In correlation technique, if the neighbor node depleted of energy of status monitoring sensor node, status monitoring biography can be aggravated The load of sensor node, when load exceedes load threshold, can cause status monitoring sensor node to fail, therefore, Lin Jujie Point current remaining sum can reflect the degree that status monitoring sensor node will not fail to a certain extent, and this is preferably Embodiment innovatively devises the more new strategy of relay forwarding node using the feature so that relay forwarding node is due to itself The current remaining sum of neighbor node is changed in time when can not meet requirement and may fail, so as to ensure that power transformation is set The reliability of standby status data transfers.
Preferably, the transmission power that status monitoring sensor node communicates with relay forwarding node is true according to the following formula It is fixed：
In formula, PSRepresent the transmission power that status monitoring sensor node communicates with relay forwarding node, PTFor relay forwarding Node is properly received power threshold, PRFor the actual receiving power of relay forwarding node, PmaxFor status monitoring sensor node Maximum transmission power, M for setting status monitoring sensor node expectation neighbor node number, m be when setting state prison Survey sensor node transmission power beWhen the neighbor node number that has of the status monitoring sensor node, P0To set Fixed unit adjustment power, f () is the value function of setting, works as M-m>When 0, f (M-m)=1, as M-m≤0, f (M-m) =0.
When preferably originally being implemented in the transmission power that determination status monitoring sensor node communicates with relay forwarding node, with shape State monitoring sensor node uses minimum emissive power (i.e.) when the neighbor node number that has with expecting neighbor node The amplitude that difference between number is adjusted as power so that the transmission power finally determined disclosure satisfy that certain neighbor node Number requirement, so as to reduce the number of times of link down, preferably improves the network performance of transformer sensor monitoring module 1, separately Outside, it is relative that transformer status data is sent with maximum transmission power, transformer status data transmitting can ensured On the premise of save the energy that transformer status data is sent as far as possible, so as to reduce the number of transformer sensor monitoring module 1 According to collection cost of energy.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than to present invention guarantor The limitation of scope is protected, although being explained with reference to preferred embodiment to the present invention, one of ordinary skill in the art should Work as understanding, technical scheme can be modified or equivalent substitution, without departing from the reality of technical solution of the present invention Matter and scope.
