基于蓝牙技术的无线数据采集系统设计

Design of Bluetooth-based Wireless Data Acquisition System

本文介绍了一种基于蓝牙技术的无线数据采集系统。该系统核心采用TI公司的超低功耗MSP430系列单片机,利用单片机内部自带的12位AD和DMA进行数据的采集,并通过蓝牙模块将采集的数据以无线电波的方式发送到终端设备。该系统具有体积小、结构简单、功耗低、速度快、采集精度较高等优点,还可以通过更换传感嚣及修改软件推广到对多种信号采集中去。

This paper introduces a Bluetooth-based wireless data acquisition system, which uses ultra-low power MSP430 MCU of TI Company and employs its own internal MCU 12 AD and the DMA for data collection to send the information collected by Bluetooth module through wireless waves. The system is small and simple with low power consumption but high speed and high precision acquisition, it can also collects variety of information through the replacement of sensors and the modification of software.
