Vehicular access communication test platform based on EUHT technology and test method thereof

Abstract

The present invention discloses a vehicular access communication test platform based on an EUHT technology and a test method thereof. A test platform is formed through adoption of an EUHT backbone network, an EUHT roadside device, a vehicle deice, an application server group, a network management server and a civil facility. The EUHT technology is introduced into a car networking system based on vehicle-vehicle and vehicle-road communication, test is performed form transmission delay, a packet loss probability and switching and maintenance performances in high-speed movement of the car networking system, the vehicle device is taken as a target to perform iperf bagging test to obtain a download speed data analysis result recorded by a vehicle-road or vehicle-vehicle intelligent terminal, the test data is transmitted to a data processing server through ping, and the data processing server calculates the packet loss probability data according to the original data of the ping to achieve concrete quantification of the network performances in the traffic information interaction process, provide core technology parameters of network performances for part of safe and non-safe traffic application of car networking and provide effective test platforms and verification means for system deployment and verification.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and relates to a vehicle-road communication test platform and a test method based on EUHT technology, in particular to a vehicle-road communication test platform and a test method based on EUHT technology. Background technique [0002] At present, the Internet of Vehicles technology is developing rapidly, and the related positioning technology, communication technology and application methods of the Internet of Vehicles have become one of the most important research contents in the field of intelligent transportation. The Internet of Vehicles technology breaks the information barriers between different terminals and participants through the information interaction between vehicles and traffic managers, so as to ensure traffic safety, improve traffic efficiency, and save energy and reduce emissions. The increasingly rich Internet of Vehicles applications have caused significant ...

Problems solved by technology

The increasingly rich Internet of Vehicles applications have caused significant bottlenecks in network capacity and network performance, seriously restricting the development of Internet of Vehicles technology. With the development of network technology, including Enhanced Ultra-Wideband (EUHT), EUHT Dedicated short-range communication (DSRC), long-term evolution (LTE) and other communication technologies that are widely used in the Internet of Vehicles environment have lower network construction costs, lower network transmission delays, lower packet loss rates, and larger networks. Capacity and high adaptability to high-speed switching and sports scenes, the use of EUHT for Internet of Vehicles research and development has obvious advantages, but there are no relevant technical standards and scientific methods for using EUHT to test Internet of Vehicles. For this reason, how to achieve Under the technical conditions of the Internet of Vehicles, the test and scientific evaluation of EUHT network performance is an important prerequisite for accelerating the application of EUHT in the Internet of Vehicles industry and marketization
