车载显示单元诊断维护系统优化设计与实现

针对目前车载显示单元监测、诊断及维护方式的局限性,通过分析研究,提出了一种新型的车载显示单元诊断维护方案,并通过设计进行了软件实现;新实现的系统软件可以自动对底层程序及应用程序进行监控及故障记录,并实现故障信息的提取,为设计和维护人员进行故障分析和故障处理提供便利;系统通过以太网进行固件及软件的升级和备份,且支持一键升级,能够极大地提升工作效率；同时,系统开发过程中融入人机工程理念,充分考虑界面美观和交互的便利性；尽量降低软件的耦合度,提高软件的可移植性。

Optimization Design and Implementation of Vehicle Mounted Display Diagnosis and Maintenance System

The current maintenance mode of the display unit has definite limitation. Aiming at solving this problem, a new diagnosis and maintenance scheme for display unit is presented in this paper.Software realization has also been carried out .The monitoring software can monitor the application program and record the fault automatically. The fault information is extracted at the same time, so that this program can provide convenience to follow-up designers to analyze and deal with the fault. Firmware maintenance tool supports firmware upgrade ,backup and a key upgrade through the connection between Ethernet and monitor. In conclusion ,this tool greatly enhances the efficiency. Software has a good interface, and can been used easily. At the same time, the design process of software minimizes the coupling degree and portability of software has been improved greatly.
