The data management method for the car networking closed test field comprises the following steps:
step 1, starting a test in a vehicle networking test field loaded with a test system;
step 2, information interaction is carried out between the vehicle-mounted unit of the Internet of vehicles and the road side equipment, and the system management equipment provides a traffic information service channel for the vehicle-mounted unit and the road side equipment; at the moment, for all information received and sent by the vehicle-mounted unit and the road side equipment through the wireless link, the data collection terminals loaded on the vehicle-mounted unit and the road side equipment record the information, load a timestamp, and upload the timestamp to a test field traffic management private network through a private network;

step 3.2, the data management storage server sorts and indexes the data according to different data sources and different data generation times for test developers to check;
and 4, extracting the data on the data storage server by the access terminal to apply.
The working scenario of this embodiment is shown in fig. 1, and the structures of the data uploading terminal and the data management storage server are shown in fig. 2 and 4. It is assumed that a test field is conducting a test on collecting a vehicle movement locus using basic safety information. The specific working process is as follows:
step 1: the test site is provided with equipment which is started, the vehicle-mounted unit broadcasts basic safety information at the frequency of 10Hz, and the road side equipment receives the basic safety information and forwards the information to the application server through the test site backbone network. The invention supervises the generation and forwarding process of all data in the process.
Step 2.1: at 12 hours, 30 minutes, 00 seconds and 10 milliseconds, the vehicle-mounted intelligent terminal of the vehicle A generates position information, namely the vehicle A, east longitude 34.373309 and north latitude 108.902346, and forwards the position information to the vehicle-mounted communication terminal so as to forward the information to the roadside equipment through the vehicle-mounted communication terminal; at the moment, information sent by the vehicle-mounted intelligent terminal is simultaneously monitored by the data terminal, the data terminal adds identity information and a time stamp to the information, the information is edited into a terminal of a vehicle A, 12:30:00.10, the vehicle A, east longitude 34.373309 and north latitude 108.902346, and the information is uploaded to a backbone network of a test field through a special network.
Step 2.2: data on the backbone network of the test field, namely 'vehicle A terminal, 12:30:00.10, vehicle A, east longitude 34.373309 and north latitude 108.902346', are classified into data uploading data by the data management storage server, and are stored and indexed.
Step 3.1: through the vehicle-mounted communication terminal network, the position information of the vehicle A, namely the vehicle A, east longitude 34.373309 and north latitude 108.902346, is received by the communication module of the roadside terminal B at 12 hours, 30 minutes, 00 seconds and 18 milliseconds, the communication module forwards the data to the intelligent terminal module for processing, and the intelligent terminal module forwards the information to the backbone network for being handed to the application server to finish data collection and application. The application collection information "car a, east longitude 34.373309, north latitude 108.902346" is also monitored by the data storage management server, and is marked as application data and stored.
Step 3.2: the communication module of the road side terminal forwards data contents 'A car, east longitude 34.373309 and north latitude 108.902346' to the intelligent terminal module, and the data contents are monitored by the data terminal of the road side terminal B and edited into 'B road side terminal, 12:30:00.18, A car, east longitude 34.373309 and north latitude 108.902346'. And the data terminal uploads the information to a test field backbone network through a special network.
Step 3.3: data on the backbone network of the test field, namely 'a terminal at the B road side, 12:30:00.18, a vehicle A, east longitude 34.373309 and north latitude 108.902346', are classified into data uploading data by a data management storage server, and are stored and indexed.
And 4, step 4: after data collection is completed, the data management storage server stores three pieces of data, namely 'vehicle A terminal, 12:30:00.10, vehicle A, east longitude 34.373309, north latitude 108.902346', vehicle A, east longitude 34.373309, north latitude 108.902346 ', vehicle B side terminal, 12:30:00.18, vehicle A, east longitude 34.373309 and north latitude 108.902346'. Without this system, there is only one piece of data "car a, east longitude 34.373309, north latitude 108.902346" on the application server.
And 5: based on the data stored by the data management storage server, we can clearly determine various problems that exist or may exist in collecting the vehicle information. If the packet loss occurs, the road side equipment is determined to be forwarded to the backbone network. Meanwhile, through the data contents of the third step and the fourth step, the network communication time delay can be obtained, and the performance state of the Internet of vehicles is reflected.
The invention relates to the field of vehicle networking test, and mainly solves the problems that the data collection and management in the vehicle networking test process have insufficient data volume, the data cannot be directly embodied through a system, the test problem can not find the reason, and the problem scene cannot be reproduced. The equipment and the method can achieve the aims of simplifying the functional modules of the car networking system, realizing full tracking and full recording of data in the car networking test process, obviously improving the test efficiency and optimizing the test process.
