摘要
针对国内某型号直升机自动测试系统的实际应用需求,设计了基于TMS320F2812的可配置参数的实时数据采集及滤波模块。模块能够对实时数据进行FIR滤波、FFT频谱分析,实现CAN通讯。在介绍硬件系统的基础上,研究了上述算法的实现,阐述了系统根据实测信号自动调用相关滤波算法的方法,并结合实际应用进行了系统分析。结果表明,该模块满足测试系统的要求,具有良好的实用性。
A reconfigurable data acqusition and FIR filtering module based on TMS320F2812 digital signal processor was designed according to the practical need of automatic testing system for the helicopter.The module can achieve FIR filtering,FFT spectrum analysis,and communication based on CAN bus.The design of circuit is presented.This paper focuses attention on the realization of the algorithms and the method that the system calls on the filtering algorithm automatically according to the measured signals.The systematic analysis is carried out in combination with the practical application.The result shows that the system meets the requirements of ATS and is available for use.
