通过对汽车传统仪表的分析比较,根据汽车电子的发展趋势,提出了基于PC/104系统的车载虚拟仪表的设计思想和车载虚拟仪表的总体设计方案、系统构成、工作原理及软硬件设计,并成功地研制出实验样品.该车栽虚拟仪表通过CAN总线进行数据传输,可对车况进行实时监控、显示,对超限工况报警和自动记忆存储,并可根据用户实际需求扩展功能.
The design of virtual instrument for automobile based on PC/104 has been presented by comparing with the traditional auto meter. The paper focuses on the development environment, system construction and operation principle. The data of the virtual instrument is transported by CAN bus, and this system can monitor in real-time, display in digit and fire the alarm to the super-speed, save the record.
