车辆检测中信号的二值化处理技术的应用研究

The Application of Binarization in Vehicle Function Testing

本文研究了一种兼容性好、通用性强、低成本的多通道信号传输技术和实现方法。对测控现场的多路传感器信号进行处理和变换,使其融合为一路基带信号后或直接进行基带传输或进行频带传输,以改进目前车辆性能检测线中所采用的信号传输技术和方法,简化信号的传送方式和工程布线、方便线路的维护和检修等。该项技术已在检测线中应用并取得了较好的效果。

Aiming at improving the traditional signal transmission, the thesis works out a kind of multi-channel signal transmission and its way of realization with fine compatibility, wide universality and low cost. The application of signal encoding to the disposal and transfer of multi-circuitry sensor signals in testing spot integrates all the signals into a single route of base band ones transmitted directly through base band or channel, which improves the traditional signal transmission in current vehicle circuitry testing, The signal transmission encoding has turned out to be effective in vehicle function testing and practical application..
