摘　　要：为在车辆运行中实时、准确地测量汽车行驶的速度、距离、所处位置的经纬度以及海拔高度,提出了一种基于CAN总线的GPS传感器应用方法,设计了一种外加TJA1050作为C8051F500物理接口,实现接口转换,并以CAN总线输出数据的测试仪器。该仪器通过软件编程由测试人员自己设定数据输出的频率,并配以按键、液晶显示和数据存储功能,从而使系统的灵活性、实用性、可靠性、实时性和准确性都大幅提高。In order to efficiently and accurately measure the speed,distance,position longitude and latitude,and altitude of vehicles in motion in real-time,an application method of GPS sensor based on CAN bus was proposed in this paper.An instrument was designed for testing the running parameters of vehicles,which had an adscititious TJA1050 as the physical interface of C8051F500 to realize the interface conversion,and output data via the CAN bus.The data output frequency of the instrument could be set through software programming by operator,and the flexibility,practicability,reliability,real-time and accuracy of the system had been greatly improved through its keyboard,liquid crystal display and data storage function.
