Design of a Multi-channel Data Acquisition System Based on MSP430 MCU

介绍了一种基于MSP430的多路数据采集系统的设计,硬件上以MSP430单片机为核心处理器,以16位A/D转换器AD7610为基础,通过切换模拟开关实现八通道单端输入和差分输入可选电压数据的实时数据采集。系统中设计有12864液晶模块和按键电路进行良好的人机交互和数据的显示。该系统设计实现了一种具有现场采集和显示并且采集方式可控制的多路数据采集器,该数据采集器具有硬件电路简单,采集精度较高,低功耗等特点,具有推广应用价值。

This paper presents a design of a multi-channel data acquisition system which based on MSP430 MCU.On hardware,the MSP430 MCU is the center processor,and the system is also based on AD7610.1t can collect the voltage data of one-port input or differential input at real time and the channels is switched by switching analog switch.The system designed 12864 LCD module and buttons circuit for good human-machine interaction and data display,A multi-channel data acquisition device which can collect data and display in real time is designed and realized.The system has these merits such as simple hard- ware,higher precision and lower power,so it has value of spread and application.
