摘要
针对传统车载电子部件需要现场更新的固有缺点,结合车联网终端自身拥有网络连接的特点,设计了一种基于GB/T32960的车联网终端的固件自更新系统,只需工程师在PC上设置新固件程序,即能完成所有车联网终端的固件程序更新。经过多次测试表明:车联网终端的固件自更新系统,能减少大量劳动量,同时能提升车联网终端固件程序更新的及时性和可靠性。基于GB/T 32960的车联网终端的固件自更新系统设计,使用4G网络和多次md5校验,达到了车联网终端固件自更新的目的,提高了工作效率。
Because traditional ECU needs to be updated, combined with the characteristics that terminal of connected car has its own network connections, a firmware update system based on ＂B/T 32960 is designed. When the engineer sets up the new firmware on PC client, all terminals can update the firmware by network. After repeated tests, the firmware update system can reduce the amount of labor and improve the timeliness and reliability of the firmware update work. Design of firmware updating system for terminal of connected car based on ＂B/T32960 achieves the target of self-updating of vehicle terminal firmware and improves work efficiency with the 4＂ network and multiple md5 checks.
