摘要
介绍了一种以PC10 4嵌入式计算机系统为核心 ,基于WinNT4 0操作系统的虚拟仪表系统的开发 ,并详细分析了该系统的结构和软件。该系统用于对车辆状态的监控 ,通过CAN总线与来自现场的各种智能节点进行通信 ,并经RS - 2 32与GPS卫星定位导航系统相互交换信息 ;使车辆的位置和姿态信息也进入监控范围。
The development of a virtual instrument system based on WINNT 4.0 and with PC 104 embedded computer system as the kernel is introduced. The structure and software of the system are analyzed in detail. The system is used for monitoring vehicle status, it communicates with various intelligent nodes coming from the field through CAN bus and exchanges information with GPS satellite positioning navigation system through RS-232 port to obtain information of positions and status of vehicle.
