摘　　要：本文设计的便携式位移-加速度振动信号测试系统其硬件体系由传感器、信号采集装置、笔记本电脑组成,将信号前置处理电路、信号采集电路、自带电源电路集成,形成信号采集装置,位移传感器与加速度传感器可置放于信号采集装置内,笔记本电脑可固定于信号采集装置上。系统的软件体系采用Delphi与Matlab混合编程,Innosetup制作安装程序。整个系统软硬件有机结合、体积小、重量轻、携带操作使用方便,特别适用于现场测试。A portable displacement - acceleration vibration signal measurement system was designed. The hardware consists of sensors, notebook computer and signal acquisition device that integrates signal acquisition, signal processing and power supply circuits together. At the same time, the displacement and acceleration sensors are put inside the device while the notebook computer is fixed above the device. The system software is written with Delphi and Matlab mixed programming and Innosetup is used to generate the setup program. In conclusion, the system is particularly suitable for field testing because of its small volume, light weight, easy to operation and portability.
