The operative scenario of the present embodiment is as shown in Figure 1, transmission terminal and data manage storage server structure in the data
Such as Fig. 2, shown in 4.Carrying out about the test for collecting vehicle motion profile using basic security information hypothesis test field.Specifically
Workflow is as follows:
Step 1: all opening of device in test site, on board unit is with 10Hz frequency broadcast basic security information, roadside device
Basic security information is received, and application server is forwarded that information to by test site core network.The present invention is in this process
The generation of middle all data of supervision, repeating process.
Step 2.1: at 12,30 when dividing 00 second 10 milliseconds, and the vehicle intelligent terminal of A vehicle generates location information " A vehicle, east longitude
34.373309, north latitude 108.902346 " is transmitted to vehicle communication terminal, to be forwarded that information to by vehicle communication terminal
Roadside device；At this point, the issued information of vehicle intelligent terminal is listened to by data terminal simultaneously, data terminal adds this information
Identity information and timestamp are compiled as " A vehicle terminal, 12:30:00.10, A vehicle, east longitude 34.373309, north latitude
108.902346 ", test site backbone network is uploaded to by dedicated network.
Step 2.2: data " A vehicle terminal, 12:30:00.10, A vehicle, east longitude 34.373309, north latitude on the backbone network of test site
108.902346 ", which are classified as data by data management storage server, uploads data, and is stored, and indexes.
Step 3.1: passing through vehicle communication terminal network, the truck position A information " A vehicle, east longitude 34.373309, north latitude
108.902346 " 30 divide 00 second 18 milliseconds of communication module by trackside terminal B to receive when 12, and communication module is by data forwarding
It is handled to intelligent terminal module, intelligent terminal module forwards this information on core network, gives application server, complete
At data collection application.Information is collected in this application, and " A vehicle, east longitude 34.373309, north latitude 108.902346 " is also by data storage tube
Reason server listens to, and is marked as being stored using data.
Step 3.2: the communication module of trackside terminal is to intelligent terminal module forwards data content " A vehicle, east longitude
34.373309, north latitude 108.902346 " is listened to by the data terminal of trackside terminal B, be compiled as " B trackside terminal, 12:30:
00.18, A vehicle, east longitude 34.373309, north latitude 108.902346 ".This information is uploaded to examination by dedicated network by data terminal
Test a core network.
Step 3.3: data " B trackside terminal, 12:30:00.18, A vehicle, east longitude 34.373309, north on the backbone network of test site
Latitude 108.902346 " is classified as data by data management storage server and uploads data, and is stored, and indexes.
Step 4: after completing data collection, data management storage server has three datas, respectively 1. " A vehicle terminal,
12:30:00.10, A vehicle, east longitude 34.373309, north latitude 108.902346 ", 2. " A vehicle, east longitude 34.373309, north latitude
108.902346 ", 3. " B trackside terminal, 12:30:00.18, A vehicle, east longitude 34.373309, north latitude 108.902346 ".If not yet
There is this system, then only has a data " A vehicle, east longitude 34.373309, north latitude 108.902346 " on the application server.
Step 5: according to data management storage server storing data, we can clearly determine to collect information of vehicles
In, exist or various problems that may be present.If only receiving 1., then it is assumed that car networking communication when packet loss occurs, if receive 1.,
3. then thinking that packet loss occurs when roadside device is forwarded to backbone network.Simultaneously by 3., 1. data content, we can obtain net
Network communication delay reflects car networking performance state.
The present invention relates to car networking testing field, mainly solve in car networking test process existing for data collection and management
The problem of data volume is insufficient, and data cannot directly be embodied by system, may cause test problem can not ascertain the reason, Wu Fafu
The problem of existing problem scenes.It is real while can achieve simplified car networking system functional module using device, method of the invention
It is complete to record now to the comprehensive trace of data in car networking test process, testing efficiency, the mesh of optimal inspection process can be significantly improved
's.
