基于ARM & μC／OS的振动测量系统设计

Design of vibration measurement system based on ARM & μC/OS

根据中国人民解放军某厂要求,设计实现了基于ARM7处理器S3C44BOX的某型航空发动机振动测量系统。该系统移植了嵌入式操作系统μC/OS,将测量系统的功能进行任务划分,完成了任务之间的同步。系统对采集的振动信号进行FFT频谱分析．并通过测得的转速信号确定相应频率的振动频谱幅度,运行结果表明,系统具有较高的精度和较好的实时性。

The paper mainly introduces a design in an ARM based embedded system which adopts ARM7 processor to be the hardware development platform.It also introduces the keypoints of transporting C/OS on the ARM processor.Besides it gives the detailed descript ion on the tasks of the system and the synchronization of these tasks.The vibration measurement system can get the spectral plot of the analog signals by the method of Fast Fourier Transfer.
