用蓝牙无线网及A/D转换实现数据采集

Bluetooth Wireless Network and A/D Converter for Data Acquisition

普通的数据采集系统是有线系统,在许多应用场合十分不便,对此文中开发了一种基于蓝牙无线通信的移动数据采集处理系统。特别是采用了轻小的蓝牙无线A/D模块作为采集硬件,从而将硬件设计开发工作简化,文中对蓝牙无线A/D模块采集的数据在微机中进行实时显示和记录,开发了数据分析管理系统,这些数据十分便于后续用各种编程语言进行处理。利用蓝牙双向通信的功能,该系统还可以方便地在微机中设置A/D采样的采样率和量化字长,可以实现2路信号及多路信号的采集。是一个方便实用的A/D采集方案。

A wireless data acquisition system based on bluetooth technique was presented. In contrary to the shortcomings of cable acquisition system which can not be used in moving cases, the system has been designed because of some characteristics of low cost simple structure. The data record and signal processing was also developed, which can set the A/D sampling parameters. In this way, a convenience and effective data acquisition system is implemented.
