摘要
为实现汽车实时数据采集并以仪表方式显示,构建以连接器硬件和虚拟仪表软件为核心的系统,由连接器硬件读取OBD接口K线实时数据,然后在PC设备上进行图形化虚拟仪表显示。在分析基于K线OBD协议的关键技术后,具体阐述了Qt开发环境下软件的设计方案。按该方案设计的汽车虚拟仪表已经实现,实测证明这种设计方案可靠,能够达到监测汽车运行实时数据的目的。
To monitoring the vehicles operating parameters,in this paper,a Qt-based virtual instrument design method is presented. In this method,the core of the instrument consists of the OBD hardware interface and application software in PC. The OBD interface hardware is used to read OBD real-time data,and the graphical virtual instrument is displayed on the PC equipment. After analyzing the key technology of K-line with OBD,the Qt serial port development software design plan was built. The designed virtual instrumentation has been implemented and some tests have been performed. The test result shows that this design is reliable and able to monitor the vehicles operating parameters.
