The above embodiment of the present invention uses wireless sensor network, convenient for field wiring, and meanwhile it is complete convenient for overall process monitoring
The assurance sludge drying dynamic change in face.
In one embodiment, sensor node random placement is in the sludge drying monitoring region of setting, after deployment
Sensor node carry out redundancy analysis, generation redundant node list simultaneously redundant node list is sent to aggregation node；Convergence
Node is before sensor node carries out sludge drying parameter acquisition according to the dormancy mechanism of setting to the portion in redundant node list
Sub-sensor node carries out suspend mode.
In the relevant technologies, random placement sensor node usually will appear the situation of 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
Optimize the deployment of sensor node, advantageously reduce the energy consumption of sludge drying parameter acquisition and transmission, extend wireless sensor network
The life cycle of network, so as to improve the reliability of sludge drying monitoring system operation.
Wherein, redundancy analysis is carried out to sensor node to specifically include：
(1) neighbor node is defined as remaining sensor node in sensor node communication range, to each of deployment
Sensor node carries out redundancy analysis, if sensor node meets following redundancy condition, which is considered as redundancy
Node：
In formula, B (i) represents the neighbor node set of sensor node i, A (∪j∈B(i)J ∩ i) represent setting monitoring
The intersection of the monitoring range of neighbor node in the monitoring range and communication range of region inner sensor node i, A (i) is passes
Monitoring range total sensor node i；DmaxFor the maximum redundancy degree of setting, DminFor the minimum redundancy of setting, Si-oRepresent sensing
Device node i is to the distance of aggregation node, SminFor the lowest distance value of monitoring region inner sensor node and aggregation node, H is dirt
Mud desiccation monitors the length in region；
(2) according to determining redundant node generation redundant node list.
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, so as 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 sludge drying parameter acquisitions and transmission,
The load capacity of single sensor node in the region is reduced, realizes the energy consumption balance of network.
If the state of redundant node is set as suspend mode, then 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 usually will sensing in the relevant technologies
The redundancy mean value of device node is usedIt represents, wherein K 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, also do not account for sensor node energy is relatively low in neighborhood situation to net
The influence of network coverage.In fact if entering suspend mode in the case where the energy of ambient sensors node is generally relatively low, it will
Relative increase aggravates the failure speed compared with low energy sensor node, drop compared with the load of low energy sensor node so as to generate
The adverse consequences of low network stabilization.The present embodiment set the 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
It occupies the information of node and suspend mode judgement is carried out to corresponding redundant node, when meeting following suspend mode condition by the state of redundant node
It is changed into suspend mode：
[1-(3/4)f·[K(W)-n(W)]]/E>1
In formula, K (W) is the neighbor node quantity of the non-suspend mode of sensor node W, and n (W) is not stopping for sensor node W
Current remaining is less than the neighbor node number of setting energy threshold in dormancy neighbor node, and f is regulatory factor, and E is setting
Coverage threshold value.
The present embodiment improves the suspend mode decision procedure in the relevant technologies, it is contemplated that sensor when setting dormancy mechanism
The relatively low situation of the state and energy of neighbor domain of node interior joint so that suspend mode judgement has more flexibility, while effectively avoid above-mentioned
Aggravation compared with low energy sensor node failure speed, reduce network stabilization adverse consequences.
Optionally, the value range of f is [1,1.2].
Sensor node easily fails in minimum energy value of the dump energy less than setting, the failure of sensor node
The network coverage will be reduced.For this problem, in one embodiment, the redundancy section that aggregation node will meet suspend mode condition
When the state of point is changed into suspend mode, the dormancy time of redundant node is set according to the following formula：
In formula, ZaRepresent the dormancy time of the redundant node a for meeting suspend mode condition of setting, ZminMost vacationette for setting
It sleeps the time, QabThe current remaining of b-th of neighbor node for redundant node a, GaNeighbor node number for redundant node a
Amount, QminThe minimum energy value of work is maintained for sensor node, Z is the delay time of setting.
Based on the problem, when the state for the redundant node for meeting suspend mode condition is changed into suspend mode by the present embodiment, base
The dormancy time of redundant node is set in the energy of ambient sensors node.
The dormancy time of redundant node is shorter when the present embodiment enables to the energy of ambient sensors node relatively low, favorably
In promoting the redundant node into suspend mode that can be waken up when surrounding sensor node will fail and enter working condition,
The covering quality of network is effectively ensured in the perception blind spot that fill sensor node may be brought in failure, improves sludge and does
Change stability of the monitoring system in terms of sludge drying parameter is acquired.
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 with reference to preferred embodiment to the present invention, those of ordinary skill in the art should
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.
