摘要
本文介绍了87C196KC单片机高速输入部件HSI的中断功能以及在ABS轮速信号采集中的应用。设计了轮速信号采集系统的软硬件,提出一种基于频率法和周期法的ABS轮速采集算法,并分析了该算法的实时性。通过单片机在线仿真实验,结果证明了硬件设计和软件算法的正确性。
The interrupt function of single chip 87C196KC high speed input component and its application to ABS wheel speed signal acquisition system is introduced in this paper. Both hardware and software of wheel speed signal acquisition system are designed. A new method which is base on the frequency and period measurement methods is proposed to process wheel speed signal, then real-time performance is analyzed. By means of on-line simulation, the test result shows that the design of hardware and software is correct.
