摘要自上个世纪七十年代诞生以来,示波器的应用越来越广泛,已成为测试工程 师必备的工具之一。然而,现有的示波器设备体积都较大且笨重,最重要的是没 有电气隔离,操作时要注意不能触电。对于现场调试或外场测试来说携带极为不 便。这也是现阶段示波器面临的一个问题。本设计则着重改善这一问题。根据所 选的单片机和蓝牙模块设计了电路,使用电路设计工具软件完成了电路原理图及 PCB 设计,组装调试了电路,编写了有关测试及调试软件。制定了实验大纲,并 进行了一系列实验研究, 并且预期了实验的结果。68528

Title Design of Virtual Oscilloscope Module of Intelligent  Mobile Phone Based on Bluetooth

Abstract

Oscilloscope was born in the seventies, and since then, the application of scope more and more extensive.It has become one of the necessary tools of the test engineers.The existing scope equipment size are large and bulky,the most important thing is no electrical isolation,when people operating it should be careful not to get an electric shock.The problem for site commissioning or field testing is very inconvenient to carry.This issue is also a problem in this stage of the oscilloscope face. The design is focused on improving the problem.I based on the selected micro-controller module and Bluetooth module to design the circuit.I completed the circuit schematic drawing and PCB design by the circuit design software.Then I assembled and tested circuit,wrote about the testing and debugging software,constituted an experimental framework and conducted a series of experimental studies,and the expected results of

the experiment.
