A wireless remote communication protocol automatic test system and a method of a vehicle-mounted terminal

Abstract

The invention discloses a wireless remote communication protocol automatic test system and a method of a vehicle-mounted terminal. The test system includes: a main control device, program control power supply, wireless communication device, GPS simulation device and CAN communication device. The method comprises the follow steps of: 1, configuring test case information to generate and execute t cases; According to the information of test cases, configuring the test script library to generate relevant test scripts. 2, sending wireless communication protocol test data to the wireless communication interface of the vehicle-mounted terminal, sending GPS simulation position data to the GPS communication interface of the vehicle-mounted terminal, and sending CAN test data to the CAN communication interface of the vehicle-mounted terminal; 3, receiving wireless communication data of that vehicle-mounted terminal to generate test result data; 4, automatically generating a test report accord tothe test result data. The invention does not depend on the real vehicle and the background environment, and improves the test coverage and accuracy. At that same time, the test case and the result judgment can be executed automatically, and the test efficiency is improved.

Description

technical field [0001] The invention relates to an automatic test system, in particular to an automatic test system and method for a vehicle-mounted terminal wireless remote communication protocol. Background technique [0002] With the gradual maturity of the Internet of Vehicles technology, the car has become more and more open from a single closed whole. At this stage, most networked vehicles realize the exchange of vehicle data and remote data by installing a wireless vehicle terminal (Telematics Box, T-box for short). Generally, the vehicle terminal needs to support a variety of local and remote communication methods, including: access to the CAN bus in the vehicle, communicate with the ECU in the vehicle; receive position signals from GPS positioning satellites; connect to the 4G network, and communicate with the vehicle background server. Among them, the communication between the vehicle terminal and the background needs to meet the requirements of the remote communi...
