车载CAN网络数据处理系统的设计

Design of Vehicular Data Processing System Based on CAN

针对现代车辆网络发展的需求,设计一种基于CAN(Controller Area Network)总线的数据处理系统。该数据处理系统通过UART(Universal Asynchronous Receiver/Transmitter)通道与CAN网关进行数据交换,完成了数据的传输与解析。通过系统功能设计,实现了实时数据显示和自动存档,以及存档信息显示的功能。各项实验数据统计结果表明:本系统的各项数据统计值与存储器的各项累加数据完全符合,能够完成指定的显示存储任务,同时也为后续车载数据信息安全的研究提供了一种研究思路。

Aiming at the needs of modern vehicle networks, a data processing system based on CAN bus is designed. The data processing system implements data exchange with a CAN gate through an UART, which realizes data processing and analysis. Through designing system function, the data rocessing system accomplishes the function of real-time data display and automatic archive, and archived information display. Based on the statistics of each experimental data, it indicates that the statistics of each data in the system are completely in accordance with the archival information of the memory, which can accomplish the task of information display and storage, and it also provides a train of thought for further study of vehicle data information security.
