摘要
日常生活中广泛存在一类对光敏感的低频、微弱但又颇受人们关注的低频小信号,运用移动互联网实现对这些信号的远程测量,具有重要意义。设计并实现了一种基于Android智能手机和移动互联网传输技术的新颖的便携式低频小信号测量系统,利用蓝牙和互联网数据传输技术将无侵入式检测的光电测量装置、用户智能手机与远程服务器端结合起来,通过便携式光电测量装置采集、远程服务器端对信号分析及反馈。该系统可用于现实生活中各种复杂、多变、动态的低频小信号进行有效的实时远程监控,并对信号异常变化进行自动预警。
It is of great significance to apply the mobile Internet to remote measurements of a wide range of light-sensitive,low-frequency and small signals in daily life.Combined with mobile Internet technology,we can measure and analyze the small signals remotely,which can effectively extract very important information from the signals.We design and realize a portable low frequency small signal measurement system based on the mobile Internet by using Android intelligent mobile phone.This system combines the photoelectric measuring device of noninvasive detection,the user and the remote server together,which can effectively monitor the status of measuring object by analyzing the low frequency small signal.
