饮用水溴离子浓度测量装置数据采集系统设计

摘要

Aiming at demand of measuring weak voltage signal acquisition and analysis for a new type of bromide ion concentration measuring apparatus in drinking water,design a collection system,including signal acquisition and upper PC display section. Weak signal of sensor output is amplified and filtered and then collected by C8051F310 MCU comes with A/D converter collects and send to LabVIEW compiled upper PC through serial port,upper computer receives data,analyze and display bromate concentration values. Experiments show that this type of acquisition system is stable and reliable,it can be used as data acquisition system for bromide ion concentration measuring device in drinking water.%针对一种基于微波感应的新型饮用水中溴离子浓度测量装置中微弱电压信号采集和分析的需求，设计了一种采集系统，包括信号采集部分和上位机显示部分。信号采集部分对传感器输出的微弱信号的放大和滤波后由C8051F310单片机自带的A/D转换器采集并通过串口发送给LabVIEW编写的上位机，上位机进行数据的接收、分析并显示溴酸盐浓度值。实验表明：该采集系统稳定可靠，可以作为饮用水溴离子浓度测量装置的数据采集系统。
