PAGE 无线三轴振动检测仪设计 PAGE PAGE I 摘 要 本论文设计的是三轴振动检测仪的角度传感器和加速度传感部分，基于飞思卡尔公司的MMA7455L芯片设计的一款可以测量X，Y，Z轴加速度的摸快。通过此模块测量X，Y，Z的加速度值，经CPU处理后，发送电路将这三个值以字节的形式无线发射至接收端，接收方单片机系统收到传来的数据后，再根据牛顿第二定理，通过程序设定算法，测出X，Y ，Z轴的偏角，并在显示器上显示。经过调试可以达到实时测量的目的，且精度比较高。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：三轴振动检测仪；加速度；角度传感；无线发射 Abstract The thesis is the design of angle sensor and acceleration sensor ,which are the parts of three axis vibration tester.It was based on freescale MMA7455L chip which can be a measurement of X, Y, Z axis acceleration, after the treatment by CPU, the sender of these three values ??the form of a byte wireless transmitter to the receiver, the receiver microcontroller system to receive these datas,and then , according to the Newtonian second law ,through setting algorithm of the program , measure X , Y，Z axis angle and show on the displayer.To debugging to achieve rea-time measurement ,and relatively high accuracy . This paper first introduces the principle of the vibration detection; Comparison of the overall system design and module program, select; then presented design and principles of the various parts of the circuit; Furthermore, the software design process and attach code ; discusses the debugging process. Keywords: three-axis vibration detector; acceleration; angle sensor; wireless transmitter 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc324581956 摘 要 PAGEREF _Toc324581956 \h I HYPERLINK \l _Toc324581957 Abstract PAGEREF _Toc324581957 \h II HYPERLINK \l _Toc324581958 1 前 言 PAGEREF _Toc324581958 \h 1 HYPERLINK \l _Toc324581959 2 振动检测原理 PAGEREF _Toc324581959 \h 2 HYPERLINK \l _Toc324581960 2.1 振动分类 PAGEREF _Toc324581960 \h 2 HYPERLINK \l _Toc324581961 2.2 振动检测原理 PAGEREF _Toc324581961 \h 2 HYPERLINK \l _Toc324581962 2.3 振动传感器的分类 PAGEREF _Toc324581962 \h 2 HYPERLINK \l _Toc324581963 3 系统设计 PAGEREF _Toc324581963 \h 5 HYPERLINK \l _Toc324581964 3.1 整体系统设计 PAGEREF _Toc324581964 \h 5 HY
