Abstract

The invention discloses a bus recorder. The bus recorder comprises a structural box and a hardware board card, wherein the hardware board card is installed in the structural box and comprises a microprocessor, a storage circuit, a power supply circuit, a Flexray interface circuit and a CAN (controller area network) interface circuit; the microprocessor is used for reading configuration files in the storage circuit and recording and storing collected bus data; the storage circuit is used for storing the configuration files and the collected bus data; the power supply circuit is used for supplying electric power to all electric circuits of the bus recorder; the Flexray interface circuit is used for accessing Flexray bus data; and the CAN interface circuit is used for accessing CAN bus data. The bus recorder can be used for recording the Flexray bus data, is compatible with the CAN bus data simultaneously, and has the advantages of high universality, small overall size, light weight and the like; and the recorded data are complete, high in reliability and high in degree of confidence, can be used for analysis and diagnosis, performance evaluation, maintenance advice giving after events and have the better economic benefit.

Description

technical field [0001] The invention relates to the technical field of vehicle bus information measurement and recording, in particular to a bus recorder. Background technique [0002] Vehicle electronic control systems and electronic control units are gradually introduced into the bus network architecture, especially the CAN (Controller Area Network, Controller Area Network) bus network has been maturely used in the design of a variety of civilian vehicles and special vehicles, and with the development of bus technology , Advanced new Flexray bus technology equipment is gradually developed and initially applied to some new vehicle designs. [0003] However, the current status quo is that the integration of test instruments, fault diagnosis and maintenance testing equipment for the vehicle bus is not high, and it is difficult to ensure reliability test verification in the vehicle design process and maintenance in the application process. In order to realize the completeness...
