Degree.
In wireless sensor network system, the basic network architecture has two kinds：A kind of is the Star based on static routing
Type structure single-hop wireless communication mode, another kind is the Mesh type structure multi-hop wireless transmission modes based on dynamic routing.
The star-like wireless sensor network structure that single-hop is wirelessly transferred, its network structure is simple, easy to implement, and whole net
The energy expenditure of each monitoring node is averaged in network, while the network delay of data packet is smaller, this topological structure from design on compared with
For complexity, the new algorithm on Mesh topological structures is still in conceptual phase at present, and the purpose of this method realizes network
Self-organizing is to reach the addition of the monitoring node under no admin state and removal.
Compare two kinds of topological structures, Mesh type topological structures complexity is high, have network capacity is big, transmission range is wide,
The advantages that data transmission credibility is high, but network-induced delay is long, monitoring node energy expenditure is uneven since the structure has
The shortcomings of even, be easy to cause monitoring data and upload not in time and network monitoring data caused by the too fast consumption of part of nodes energy
Imperfect or even local paralysis.Star type topological structures are although relatively simple, transmission range than relatively limited, but this transmission side
Formula tissue is simple, is easy in industry spot stable operation.For the wireless sensor network for the rolling bearing for needing to design in paper
Network monitors system, Star types wireless sensor network can embody the consumption of each node energy uniformly, data upload in time
Advantage, this is the precondition that system is accurately completed to monitor and diagnose, meanwhile, it can be opened up by way of increasing relay node
Open up the coverage of network.Therefore, the wireless sensor monitoring network of design uses Star Basic Topologicals.
In view of the finiteness of single-hop networks transmission range, stelliform connection topology configuration is improved here.In industry spot,
The installation site of monitoring node is determined by the specific situation of equipment and production line, although opposite in industry spot monitoring node quantity
It is limited, but since device distribution has high concentration and high degree of dispersion double grading, the distribution of monitoring node also has
Have and equally have the quality that, in order to avoid single-hop transmission scope limitation the system by the way of relay node is added
Increase the transmission range of data.Meanwhile upload comprehensive, sheet to improve the timeliness of data transfer and malfunctioning node data
System is using normal node and the operating mode of malfunctioning node monitoring data subchannel transmission, when the bearing that node is monitored is in
During normal operating conditions, monitoring node uploads its time domain and frequency domain character parameter for being calculated by master network；When monitoring saves
When point is in abnormal operation, monitoring node uploads its bearing vibration data collected by system alarm network
Full content.Improved by above two parts, ultimately form the tree network topology structure of double aggregation nodes.
WSN Protocol Designs use the Cluster Networks topological structure of tree-like double aggregation nodes, i.e., have two remittances in whole network
Poly- node, is main aggregation node and alarm aggregation node respectively.Network has two level and three-level both of which, is respectively intelligent testing
Shake node, aggregation node two-stage pattern or intelligent vibration measuring node, relay node, aggregation node three-level schema.Vibration measuring node into
Collection, processing and the analysis of row vibration data, it would be desirable to which the data of upload are uploaded to corresponding aggregation node；Aggregation node is then united
The sequential of each node, is on the one hand sent to vibration measuring node, separately by the control instruction for coming from server end in one control network
On the one hand the data that intellectual monitoring node uploads are collected, and are sent to server end, server carries out the signal of collection in worksite
Processing, storage, and accident analysis and diagnosis are carried out, meanwhile, server can also send instruction to obtain expection to vibration measuring node
Effect, such as change feature Value Types, alarming value and the real-time collection for carrying out data.
Since vibration signal is high-frequency signal, and equipment is all in most cases normal work, if this measured
A little data are all transferred to server, can so cause substantial amounts of data redundancy, memory space can be wasted largely, it is also possible to be made
It is unstable into system, since monitoring device is in the state worked normally in most cases, at this time without carrying out accurate event
Barrier analysis, need to only obtain the partial feature value of equipment, therefore individual node volume of transmitted data is smaller；Monitored in practical application
The situation that equipment is in malfunction is less, but needs to obtain the more complete information of equipment in this case, as failure afterwards
Rigorous analysis, it is therefore desirable to which the data volume of transmission is big.Data analysis and feature extraction are carried out by intellectual monitoring node, and in terms of
Calculation result is diagnosis basis, so as to reach the target for reducing data sending amount.
The data that single sensor measures, will necessarily cause the omission of effective fault characteristic information, increase fault diagnosis knot
The contingency of fruit.The signal data for gathering at the same time and analyzing multiple passages can obtain more useful letters for including fault signature
Breath, so as to improve the accuracy and confidence level of fault diagnosis result.Technology for mechanical fault diagnosis is that research mechanical equipment is run
Status information, the state and failure of monitoring, diagnosis and indication mechanical equipment, a science skill of guarantee mechanical equipment safe operation
Art.Its necessary condition is exactly that fault-signal feature is extracted from operation state signal, for the early stage of mechanical system
Failure, in the budding stage, its performance is little with the difference under normal condition, often appears as unstable small-signal.This
Outside, the Weak fault signal of early stage is submerged in strong background noise, shows the non-stationary nonlinear characteristic of complexity so that early stage
The small-signal of failure is more difficult to extract.
Vibration measuring node in master network frequency range and is in listening state after power-up initializing, is receiving main aggregation node
Invitation add after network instruction, vibration measuring node sends the addition network information to aggregation node, and main aggregation node judges new section
Whether vibration measuring node can add network to point, send response instruction afterwards, including node adds successful flag bit, adds network
Success.
The characteristic value parameter upper limit of setting is included in the code that main aggregation node or relay node issue vibration measuring node.
Program is calculated feature value parameter and is contrasted with setting value by vibration measuring node, if being less than setting value, directly returns number
According to parameter, if above characteristic value, then application is needed to exit network to be added in warning net.
The process to exit network is similar with the process for adding network, after the upload data command of main aggregation node is received,
Vibration measuring node sends the information that exits network, and after main aggregation node determines that the node can exit network, sends response instruction afterwards,
Successful flag bit is added including node, adds network success.
In addition to normal exit network, vibration measuring node may fail during work, and the node of failure cannot
The instruction sent to aggregation node carries out feedback, and in this case, aggregation node can count the number that node is not fed back, such as
Fruit number exceedes certain number, then it is assumed that the vibration nodal point fails, and reports to server.After vibration measuring node is replaced, it is added
It is also to use module described above with exitting network.
The availability of following experimental verification node addition and the program that exits network is designed herein.Send broadcast singal and invite section
Point adds main aggregation networks；Node replys the ACK addition network informations after receiving invitation instruction；It is true that aggregation node replys vibration measuring node
Recognize addition network, node adds network success；Vibration measuring node sends the information that exits network to aggregation node；Aggregation node, which receives, to move back
Response instruction is sent after going out application；Node successfully exits network.
