摘要
车身电子系统越来越复杂,针对车身电子功能的高效测试,研发了一种基于事件触发协议的车身电子自动测试系统。该系统包括系统软件,控制硬件和被测车身系统,采用串口和CAN总线两种数据通讯方式。系统采用LabVIEW2011进行开发,通过CAN总线形成闭环结构,通过导入事件触发文件实现不同型号车身系统的通用自动测试,通过导入范围选择文件进行自定义式的误差测试。系统按照时序自动输出用于测试车身电子系统的各类信号和参数,通过反馈信息判断车身电子系统的各项功能的有效性。系统的实际应用表明,该系统满足了实时性、准确性和高效性的要求。
With vehicle body electronic system more and more complex, this paper develops a vehicle body electronic system automatic test system based on event trigger protocol for testing vehicle body electronic system functions. The system includes the system software, control hardware and vehicle body electronic system three parts, using both a serial port and CAN bus data communication methods. The system is developed by LabVIEW2011, through CAN bus to form closed loop structure, achieving general automatic test of different type vehicle body electronic system by importing the event trigger file, achieving custom style error test by importing the range select files. The system according to the time sequence automatically output for testing all kinds of signal and the parameters of electronic systems and ear body through the feedback information to determine the effectiveness of the various functions of vehicle body electronic system. The actual application shows that the system meets the requirements of the real-time, accuracy and etticiency.
