【摘要】 针对现今振动分析仪的不足,介绍了基于μC/OS-II和ARM7的一款便携式振动测量分析仪。将系统的功能进行任务划分,完成任务间的同步与通信。对采集的振动信号进行FFT频谱分析,进行动平衡实验,并与实验室的商品化仪器测得的结果进行比较。更多还原

【Abstract】 Describes a portable instrument of vibration measurement and analysis based on μC/OS-II and ARM7 for the insufficiencies in the vibration instruments nowadays.Tasks of the system are detailed designed,the synchronization and communication of the tasks are achieved.Frequency-domain analysis is accomplished by method of Fast Fourier Transfer.Compare with the result of the former instrument when verify the dynamic balance method.更多还原
