To monitor the status of vehicle fuel consumption, and to solve abnormal fuel consumption for logistics enterprises, the fuel consumption monitoring system based on wireless USB ( WUSB) has been designed and developed. The physical structure of the system is introduced and analyzed, it includes three parts, the vehicle loaded intelligent terminals, the management subsystems of convoys, and the host WUSB data acquisition systems. The communication protocols between the host computer and the slave computer are designed and implemented. The host application programs are designed and developed for management and control purposes. The tests show that the system features high stability, and well solves the monitoring task of fuel consumption.%为监控物流企业车辆的油耗使用状态,解决异常油耗等问题,设计开发了基于无线USB(WUSB)的物流车辆油耗监控系统.首先,分析介绍了油耗系统的三部分组成结构,即下位机嵌入式车载智能终端、上位机车队管理子系统和上位机无线USB数据采集子系统;然后,设计实现了上下位机之间的通信协议;最后,设计开发了主机应用程序,以实现上位机的管理和控制.试验表明,该系统稳定性高,能较好地解决车辆油耗监控问题.
