摘　　要：设计了一套适合汽车传感器非连续信号性能测试的数据采集终端,利用NI-6259数据采集卡将采集终端的数据和PC机连接起来,组成一套完整的汽车传感器性能测试监控系统。该系统能够实时显示高电平、低电平的最大值、最小值、平均值,占空比,频率和倍频与否,被测信号的频率范围在1～8 kHz.测量数据与界面上指定的数据范围对比,自动判断是否合理,并分类保存。A set of data acquisition terminal for automotive sensor non-continuous signal performance testing was designed. It is connected together to form a complete set of automotive sensor performance test monitoring system using NI - 6259 data acquisi tion card and PC data collection terminal. The system can display real-time maximum, minimum and average of high level and low, duty cycle, frequency, and flipping or not. The measured signal frequency range is from 1 Hz to 8 kHz. The measured data is contrasted to the specified range of the interface data, automatically determined whether it is reasonable, and classified saved.
