Embodiment 1

[0082] The LTE-V2X dynamic performance test of this embodiment is carried out in the high-speed scene test, the vehicle driving route is pre-specified, and the vehicle driving speed is set to 120km / h (ie 33m / s), when the vehicle travels on the specified route at this speed , receiving / sending 10 packets per second. Further, the test distance range [0m, 100m] (the test distance is 100m) is set in combination with the actual test scene, and the test sample accuracy is 0.5% / 100m.

[0083] According to the method of the present invention, after the above-mentioned test parameters are determined, the number of times the vehicle travels on the prescribed route can be counted according to the existing parameters. In this example, when the test distance interval is [0m, 100m] and the test sample accuracy is 0.5% / 100m, in order to meet the test sample accuracy standard, it can be determined through statistical analysis that this test needs to be within 100m Obtain more than 200 test s...

Embodiment 2

[0086] This embodiment is based on the first embodiment, and the dynamic performance of LTE-V2X is tested according to the test scheme generated in the first embodiment.

[0087] Specifically, in this embodiment, two vehicles, two OBUs, and two test devices are configured for a specific test. Install the two devices under test on two cars respectively, and connect the test device and the device under test through the network port. Further, the two vehicles are moved to the high-speed scene test environment, and the two vehicles are driving on the prescribed route at a speed of 120km / h. Data transmission is performed at the sending and receiving packet speed of a data packet. During the test, the two cars and the LTE-V2X equipment continued to work according to the above standards until the two cars stopped when they drove 7 times within the test distance interval of 100m. In addition, in order to improve the accuracy of the test results, several rounds of tests may also be p...

Abstract

The invention provides an LTE-V2X dynamic performance test method and device under an external field environment. The method comprises the following steps: setting test parameters for LTE-V2X dynamicperformance test according to a preset strategy; summarizing test execution data by utilizing the test parameters; generating a test scheme according to the test parameters combined with the executiondata; and carrying out LTE-V2X dynamic performance test according to the test scheme. The method regulates accuracy of the external field test data analysis result, enables accuracy of a test sampleto be adjustable and can also improve accuracy of the test result; and besides, the method provides a mode of replacing the fixed-point test result by the test result of the test distance interval, solves the problem that the test result under a single distance cannot be obtained steadily and continuously, ensures accuracy of the test result, fills the blank of test specifications at home and abroad, allows the LTE-V2X dynamic performance under the external field environment to be tested in a high-precision, fast and efficient manner and solves the problems of large workload or lack of accuracy in an existing test scheme.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an LTE-V2X dynamic performance testing method and device in an external field environment. Background technique [0002] With the continuous development of automobile technology and radio technology, automobile technology and radio technology have shown the trend of mutual integration. Moreover, with the proposal of ITS (Intelligent Transportation System, Intelligent Transportation System), the interactive fusion of information between vehicles, pedestrians and roadside infrastructure has been further realized. In addition, LTE (Long Term Evolution, long-term evolution) technology is becoming more and more popular, making it possible to realize direct communication between vehicles and vehicles, vehicles and roads, and vehicles and people based on LTE technology, so as to meet the needs of vehicles and vehicles, vehicles and roads, Low-latency, high-reliab...
