摘要:

CAN總線(xiàn)作為車(chē)用網(wǎng)絡(luò )的主要應用總線(xiàn)技術(shù),通過(guò)CAN總線(xiàn)獲得汽車(chē)運行時(shí)的實(shí)時(shí)數據成為汽車(chē)電子系統研發(fā)、維修及故障分析的主要手段；在對傳統CAN總線(xiàn)檢測卡分析及研究的基礎上,為了使移動(dòng)PC更加便捷地分析及記錄汽車(chē)CAN網(wǎng)絡(luò )中的數據,使基于串口通訊的系統及應用軟件能夠方便地繼承使用,設計了基于XMC4500單片機的汽車(chē)CAN網(wǎng)絡(luò )檢測卡；實(shí)現了將汽車(chē)CAN網(wǎng)絡(luò )中的數據通過(guò)USB端口虛擬的高速串口傳輸至上位機、實(shí)時(shí)備份相關(guān)數據到Micro SD卡中的功能；實(shí)驗數據顯示在最高1 000 kb/s的傳輸速率下,能夠100%正確接收及存儲相關(guān)數據,滿(mǎn)足對該卡實(shí)時(shí)性和可靠性的要求。

Abstract:

Vehicle CAN bus network is the main application of bus technology, obtained through the CAN bus when the car is running real-time data for automotive electronic systems development, maintenance and fault analysis the principal means. Basis on traditional analysis of CAN-bus test card, in order to make the mobile PC more easily analyze and record vehicle CAN network data, so that based on serial communication systems and application software can easily inherit, designed XMC4500 based microcontroller automotive CAN network testing card, realized the vehicle CAN network data and transmit it to upper PC through the USB port high-speed virtual serial transmission, real-time backup-related data to the Micro SD card function, experimental data show that at the highest 1000kb / s transfer rate, can be 100% correct receiving and storing data, the card meets the requirements of real-time and reliability.
