信号检测综合训练说明书题目：振动信号检测系统设计学院：电气工程与信息工程学院班级：电子信息科学与技术（2）班姓名：江峰学号：11260204指导老师：缑新科2014年12月04日摘要振动从形式上看，有的是来回摆动，有的是往复直线运动，有的是旋转运动等，种类很多，形式不一，但它们都有一个共同的特点，即物体在运动过程中总是在它自己的平衡位置附近，一次又一次地重复地运动着。因此，我们把物体在其平衡位置附近所做的往复性的运动称为振动。研究振动的目的是为了了解各种机械振动的现象的机理，破译机械振动所包含的大量信息，进而对设备的状态进行监测，分析设备的潜在可能故障。本课题主要选用位移传感器结合微分电路测得最大位移，最大速度，最大加速度，并且利用LCD显示振动信号。本论文首先介绍了振动检测的原理；其次介绍了整体系统的设计和各模块方案的比较，选择；接着介绍了各部分电路的设计及原理；再者介绍了软件设计流程并附上了程序代码；最后论述了系统的调试过程。关键词：单片机；振动；加速度；检测目录摘要·········································································································I1前言·········································································································12振动检测原理·····························································································22.1振动分类·····························································································22.2振动检测原理······················································································22.3振动传感器的分类···············································································23系统设计···································································································53.1整体系统设计······················································································53.2方案设计·····························································································53.2.1数据采集模块················································································53.2.2液晶显示模块················································································54硬件设计···································································································94.1单片机最小系统··················································...
