摘要
以TMS320VC33为随机共振检测系统处理核心,介绍了强噪声背景下检测微弱信号的随机共振技术,TMS320VC33的性能特点,基于CPLD的自动数据采集电路,与PCI桥CY7C09449的接口,系统的软硬件设计与调试。该系统在电源设备故障信号检测应用中取得了很好的效果。
Using TMS320VC33 as a processing core in stochastic resonance detection system, this paper mainly presents stochastic resonance technology in weak signal detection under strong noise background, capability and character of TMS320VC33, automatic data-acquisition circuit based on CPLD. Interface between TMS320VC33 and CY7C09449 of PCI bridge are also put forward detailed. Design and debug thinking both in software and hardware are concerned synchronously. The designed system has taken a good effect on power device fault signal detection. The result is applausive,
