摘要

针对目前振动信号测试系统的不足，设计了一种基于ARM和加速度传感器的振动测试系统。该系统能够感应多路振动加速度信号，同时完成对信号的滤波，采集和分析处理。系统由传感器部分，数据采集部分，微处理部分和计算机系统组成。微处理部分采用基于LPC2129为核心的嵌入式微处理器；数据传输采用可靠稳定的CAN协议，以保证数据传输的正确性。系统采用USB供电方式，结构紧凑，测量操作方便。最后从人体动力学角度验证了本系统的性能。

Abstract

In view of the present vibration signal detecting system's insufficiency, this paper designed one kind of vibration detecting system based on ARM and Accelerometer。The system induced the multi-channel vibration acceleration signal and completed signal filting, acquiring and analysis processing. The system was composed by sensor part, data acquisition part, micro- processing part and computer system. The micro-processing part used LPC2129 as the core embedded micro-processor and the data transmission used the reliable stable CAN protocol to make the data transmission accuracy. The system selected the USB power supply method and the structure was compact and well operation. Finally the system is validated by the example of Human Body Dynamics.
