Vehicle network based remote wireless testing system and testing method

Abstract

The invention relates to the technical field of wireless testing, in particular to a vehicle network based remote wireless testing system and testing method. The system comprises a vehicle network main testing device, a network server and a browser terminal. The method comprises the following steps: obtaining and analyzing the configuration information of a vehicle to be tested and setting and initializing a testing module and parameters of the testing module; sending an item test message to an in-vehicle network CNA bus of the vehicle to be tested; and carrying out statistics and analysis according to a generated network message and displaying and outputting the statistic and analysis results through the browser terminal. Interaction with the vehicle and the network server is realized through the portable vehicle main testing device; remote real-time vehicle network testing and analysis can be carried out by virtue of a wireless network; the testing does not need to be carried out in the vehicle, thus being convenient to use; analysis and guidance given by the network server can be displayed and output by the browser terminal; non-professional technical staff also can perform simple remote testing, thereby saving labor and improving the testing efficiency.

Description

technical field [0001] The invention relates to the technical field of wireless testing, in particular to a remote wireless testing system and testing method based on a vehicle network. Background technique [0002] The development of automotive electronic control technology makes the structure of automotive electronic control system more and more complex. As the types of data and reliability requirements used to communicate between these systems vary, the number of wiring harnesses also increases. In order to reduce the number of wiring harnesses in the vehicle network, the CAN bus is widely used to build a vehicle network. As the media basis for the interaction of various controllers, the vehicle network affects the operation of the vehicle electronic control system, and then affects the economy, power, safety and reliability of the vehicle. However, with the increase of vehicle network nodes, the load of the vehicle network also increases accordingly. In order to ensure...

AI Technical Summary

Problems solved by technology

It mainly has the following problems: 1. The cost of this set of equipment is relatively high, and the functions of the statistical analysis module are relatively scarce, and secondary development and expansion should be carried out according to the vehicle network test specifications; 2. During the actual vehicle test process, due to the lack of wireless network 3. The test process needs the on-site control support of notebook computers and other equipment, which is limited by the space of the vehicle, which brings great inconvenience to the carrying and operation of the existing complete test system. Inconvenient; 4. When an abnormality occurs in the test, it is often only possible to rely on the personal experience of the network engineer or contact the assistance of a remote related engineer, lack of test guidance and diagnostic help, increase test maintenance time, and reduce test efficiency
