摘要
针对科氏质量流量传感器时变信号模型，研制以TMS320F2812DSP芯片为核心的数字信号处理系统，采用自适应陷波滤波和SGA算法，实时实现处理时变信号。由信号发生器、信号处理系统和PC构建了测试平台，解决时变信号发生和信号处理方法测试的问题。测试结果表明，该系统和实现的算法是有效的。
Aiming at the time-varying signal model of Coriolis mass flow sensor, a digital signal processing system is developed with TMS320F2812 DSP chip, and the adaptive notch filter and sliding Goertzel algorithm are adopted to process the time-varying signal in real time. A testing platform is built with a signal generator, the signal processing system and a person computer in order to solve the problems of generation and testing of the time-varying signal. The test results show that the system and algorithms studied are effective.
