The specific embodiment of the invention is described in detail below in conjunction with the accompanying drawings.
Passive type wireless network interception system includes software systems, monitoring main frame, data transmission network and interception node.Detect
Listen node to be dispersed in the middle of wireless sensor network, data transmission network is transported to after the packet pretreatment that will be received；Number
The data that will be collected into according to transmission network are sent to monitoring main frame；Software systems are installed on monitoring main frame, software systems are several
According to processing center, it is merged to data, is stored, and the data after fusion are carried out with protocol analysis, realize test network
The network test work of synchronization, network working state monitoring etc..
Monitoring host software system development platform uses Microsoft Visual Studio.Net 2010, using C# languages
Speech programming.Program mainly includes serial communication modular, clock synchronization module, data fusion module, data memory module, data point
Analysis module, data disaply moudle and database.Database uses SQL.Serial communication modular be responsible for the order of test node and
Data interaction；Clock synchronization module is responsible for synchronism detection network；The data of each test node are melted in data fusion module
Close；Data memory module is responsible for the data after batch storage fusion to SQL database；Data analysis module is according to wireless senser
The procotol parsing data of network, and provide various test indexs；Data disaply moudle is with various graphics modes such as form, post
The modes such as shape figure, pie chart, curve map show the data after analysis, and draw the topological structure of network.
Its workflow is as shown in Figure 1：
1. serial communication modular：It is the data input module of whole system, the main order sum being responsible for test node
According to interaction, the data that detection node will get are sent to main frame where protocal analysis software, serial communication modular by serial ports
Receive and send it to data fusion module after data and carry out data fusion.
2. clock synchronization module：Mainly responsible synchronizing network, makes the machine consistent with the clock in network；Utilize the time simultaneously
The synchronous data to participating in fusion are screened, and filter out wrong data.
3. data fusion module：The time that the serial data and S2 passages that the module receives the transmission of S1 passages simultaneously send is same
Step data, and S1 channel datas are screened by S2 passages, abandon and postpone larger serial data, only to the nearlyer time period
Interior data carry out fusion treatment；This module is mainly responsible for for the network data that different nodes are obtained being analyzed arrangement, and will
Similar data are merged, and more accurate data message is sent to data memory module by S3 passages.
4. data memory module：The fuse information that will be arrived by S3 channel receptions is stored to database by S4 passages respectively
In, S7 passages be sent to data analysis module.
5. data analysis module：It is main to be responsible for parsing data according to the procotol of wireless sensor network, and to data
Display module sends analysis result.The real time data that the module can be sent by S7 channel receptions data memory module is solved
Analysis, it is also possible to parsed by the storage information in S5 passage reading databases.
6. data disaply moudle：It is the output module of whole system, it is main to be responsible for being interacted with user.User can lead to
Data in interface selection data analysis module analysis real time data or database are crossed, its analysis result will be returned by S6 passages
Data disaply moudle, and shown with the diagrammatic form of user's selection on interface.
By data acquisition channels S7 so that program can respectively carry out real-time data analysis and data review andanalysis work(
Energy.The implementation method of this module is the interpolation data transmission code in data memory module, in data are stored in database it
After send the data to data analysis module；Data reception code is added in data analysis module simultaneously, realizes that two modules are led to
S7 interfaces are crossed to be communicated.
The specific implementation of S7 interfaces is：Static overall variable RTData (List are stated in a program<string>) and update
, can be added to data value in queue RTData when data memory module receives new real time data by mark ND (bool),
And ND is set to true；Data analysis module can be judged ND always when real-time data analysis are carried out, if ND is true,
Treatment then is analyzed to all data in RTData, ND is then set to false, and empty RTData queues.
The present invention selects SQL database, in storing data into far-end server.SQL database supports that multi-client is same
When access, can thus realize many softwares simultaneously run, improve software work efficiency, increase monitoring range, preferably carry out
Network monitor analysis work.
As shown in Fig. 2 the operation to database is carried out by data storage service, the module start after to set
User name and password login database, and database realizing data are assigned to by the order that the port for setting will receive
The functions such as storage inquiry.Need to be converted into Sql sentences and be sent to data storage storage order in data memory module of the present invention
Service, then data storage service carries out data loading operation again.
Part specific implementation code is as follows：
String Order=string.Format (" INSERT TASK_YJ SQL='{ 0 } ', CHECKDATA='
{ 1 } ', TRANS='{ 2 } ', TARGETS='{ 3 } ', INSYSTIME={ 4 } ", package.Sql,
package.Checkdata,pack.Trans,package.Targets,string.Format("to_date('{0}','
yyyy-MM-ddhh24:mi:ss')",DateTime.Now))；
Dbacer.ExecuteNonQuery(Order)；
String Order are the Sql sentences of data storage in above code, Dbacer.ExecuteNonQuery be with
The order that data storage service is communicated.
String SQL=string.Format (" WHERE 1=1AND [METHOD]=' { 0 } ' AND [TASKNO]='
0'",package.Method)；
Criteria criteria=new Criteria (SQL)；
IList SignalList=DbWriteAcer.Select (typeof (Task), criteria)；
More than several line codes be data analysis module carry out it is required when data query is analyzed use, string SQL and
Querying condition is converted into Sql sentences by Criteria criteria, and IList SignalList are that database is inquired about simultaneously
Query Result is returned in List forms, data parsing is carried out.
Several interception nodes in wireless sensor network, it is necessary to by data transmission network make its connect into one it is complete
Kind test network.At present, the design of test network is broadly divided into based on usb hub and based on two kinds of Ethernet.
Data transmission network based on usb hub：
Data transmission network based on usb hub is main by the corresponding USB line of each interception node and usb hub group
Into its structure is illustrated in fig. 3 shown below.
Each interception node is dispersed in tested wireless sensor network, and the USB interface of interception node expands biography through a signal
Defeated module is connected to the downlink port of child node usb hub, and each child node usb hub is connected to its total node usb hub,
Data transmission network is so constituted into tree topology, root node usb hub by cascade usb hub (most 5 level connection)
Uplink port connection monitoring main frame, such interception node can by packet be passed up to monitoring main frame, it is possible to receive
The instruction that monitoring main frame sends.
Data transmission network based on Ethernet：
With too net is carried out as transmission forward position, data transmission network turns data transmission network according to Ethernet including serial ports
Ethernet module, Ethernet switch and communication line, its construction are as shown in Figure 4.
Serial ports turns ethernet module and the serial ports of different interception nodes is connected into Ethernet switch, realizes that data are accurately passed
Give monitoring main frame.It is identical, monitoring main frame by Ethernet come to corresponding interception node send start, terminate, switching channel and
The different instructions such as adjustment radio frequency power output.According to Ethernet protocol, its be at best able to 255 IP address of distribution for serial ports turn with
Too net module and monitoring main frame is used, and this quantity can typically meet the demand of interception node in test network.
The beneficial effects of the invention are as follows：
