Reason, electric power system dispatching control provide foundation.
In one embodiment, it after disposing sensor node, needs to carry out redundancy analysis to sensor node, specially：
(1) multiple sensor nodes are affixed one's name to inside the monitoring region of setting；
(2) redundancy analysis is carried out to each sensor node, if sensor node meets following redundancy condition, by the sensing
Device node is considered as redundant node：
In formula, it is remaining sensor node in sensor node communication range to define neighbor node, and A (i) is indicated
The neighbor node set of sensor node i, Ω (∪j∈A(i)J ∩ i) indicate setting monitoring region inner sensor node i prison
The intersection of range and the monitoring range of neighbor node in communication range is controlled, Ω (i) is the total monitoring models of sensor node i
It encloses；GmaxFor the maximum redundancy degree of setting, GminFor the minimum redundancy of setting, di-oIndicate sensor node i to aggregation node
Distance, dminTo monitor the lowest distance value of region inner sensor node and aggregation node, L is the length for monitoring region；
(3) redundant node list is built according to determining redundant node and redundant node list is sent to aggregation node.
Optionally, above-mentioned redundancy analysis can be carried out by computer.
The present embodiment provides measurement index by the setting of redundancy condition to carry out redundancy analysis to sensor node,
Improve the efficiency that redundancy analysis is carried out to sensor node.It is superfluous by maximum redundancy degree threshold value, minimum when setting redundancy condition
The setting of remaining threshold value, by the control of redundancy threshold value in certain zone of reasonableness, it is ensured that the precision of redundancy analysis.
When the present embodiment closer to the sensor node of aggregation node to carrying out Redundancy Analysis, according to redundancy condition,
Corresponding redundancy threshold value bigger, this correspondingly reduce apart from aggregation node closer to region in sensor node be confirmed as
The quantity of redundant node, to be beneficial to reduce apart from aggregation node closer to region in sensor node suspend mode rate so that
Apart from aggregation node closer to region can have the work that more sensor nodes carry out wind power plant operation data acquisitions and transmission
Make, reduce the load capacity of single sensor node in the region, realizes energy consumption balance.
In one embodiment, aggregation node according to the dormancy mechanism of setting to being determined as the sensor node of redundant node
Suspend mode is carried out, remaining sensor node constitutes wireless sensor network by Ad hoc mode, starts to acquire in sensing range
Wind power plant operation data.
In the related technology, random placement sensor node usually will appear the case where bulk redundancy node, bring information superfluous
It is remaining excessively, energy excess waste the problem of.To solve the problems, such as this, the present embodiment to redundant node carry out suspend mode by way of come
The deployment for optimizing sensor node advantageously reduces the energy consumption of wind power plant operation data acquisition and transmission, extends wireless sensor
Network morals, to improve the reliability of system operation.
In one embodiment, set dormancy mechanism as：
(1) aggregation node determines the information of neighbor nodes of each redundant node in redundant node list；
(2) redundant node for receiving suspend mode judgement information interacts the information for obtaining neighbor node by node, and according to neighbour
The information for occupying node carries out suspend mode judgement to corresponding redundant node, when meeting following sleep condition by the state of redundant node
It is changed into suspend mode：
In formula, N (μ) is the neighbor node quantity of the non-suspend mode of sensor node μ, and n (μ) is not stopping for sensor node μ
Current remaining is less than the neighbor node number of setting energy threshold in dormancy neighbor node, and k is regulatory factor, and η is setting
Coverage threshold value.
Optionally, the value range of k is [1,1.2].
If the state of redundant node is set as suspend mode, the coverage rate of wireless sensor network can be reduced, if right
The state of multiple redundant nodes is set as suspend mode simultaneously, it will a large amount of perception blind spot occurs.It in the related technology usually will sensing
The redundancy mean value of device node is usedIt indicates, wherein N is the number of nodes in sensor node neighborhood, and in redundancy
By the mode setting of the sensor node as suspend mode when degree mean value is more than the coverage threshold value set, this mode is not examined
Consider the state of sensor node neighborhood interior joint, does not also account for sensor node energy is relatively low in neighborhood situation to net
The influence of network coverage.In fact if the energy in ambient sensors node is universal lower into suspend mode, it will
Relative increase aggravates the failure speed compared with low energy sensor node, drop compared with the load of low energy sensor node to generate
The adverse consequences of low network stabilization.The present embodiment improves suspend mode judgement side in the related technology when setting sleep condition
Formula, it is contemplated that the relatively low situation of the state and energy of sensor node neighborhood interior joint so that suspend mode judgement is more flexible, together
Shi Youxiao avoids above-mentioned adverse consequences.
In one embodiment, the state for the redundant node for meeting sleep condition is changed into suspend mode by aggregation node
When, the dormancy time of redundant node is set according to the following formula：
In formula, TaIndicate the dormancy time of the redundant node a for meeting sleep condition of setting, TminFor the most vacationette of setting
It sleeps the time, EabFor the current remaining of b-th of neighbor node of redundant node a, maFor the neighbor node number of redundant node a
Amount, EminIt is the delay time of setting that the minimum energy value of work, T are maintained for sensor node.
Sensor node is easy failure, the failure of sensor node in minimum energy value of the dump energy less than setting
The network coverage will be reduced.Based on the problem, the state for the redundant node for meeting sleep condition is changed into not by the present embodiment
When sleep mode, the dormancy time of redundant node is set based on the energy of ambient sensors node so that ambient sensors node
Energy it is relatively low when redundant node dormancy time it is shorter, be conducive to promote the redundant node into suspend mode can be surrounding
Sensor node will wake up and enters working condition, the perception that fill sensor node may be brought in failure when will fail
The covering quality of network is effectively ensured in blind spot, improves wind power plant remote real time monitoring system in acquisition wind power plant operation data side
The stability in face.
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 being explained in detail to the present invention with reference to preferred embodiment, those skilled in the art answer
Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and range.
