【摘要】 为了解决多数测振传感器在超低频测量上不足的问题,文中采用零极点配置法,设计了一个以TMS320LF2407作为主控芯片的电路,同时DSP通过程序设计了一个数字滤波器。当振动信号采集后,原测振传感器的低频特性通过此系统得到补偿,从而扩展了其低频范围,具有很强的实用性。更多还原

【Abstract】 A system is introduced to solve the shortage of most vibration sensors in ultra-low frequency measurement.Also a method is showed that adopting the zero-pole redisposing.A circuit is designed whose CPU is TMS320LF2407.A digital filter is designed in DSP’s program.After signal acquisition,the low frequency characteristic of vibration sensors can be compensated through the system.And its low frequency limits is expanded.As a result,the system can be used with its good practicability.更多还原
