摘要
介绍一种基于HART协议的金属管浮子流量计的设计方案。应用磁阻传感器测量金属管浮子的角位移,利用HT2015和AD421实现HART协议通信物理层,并叙述了MSP430单片机的软件编程,实现了各项功能和HART通信。
A metal tube rotameter based on HART protocol is designed. A magnetic resistive sensor is used to measure the angular displacement of metal rotameter,HT2015 and AD421 are used to realize the physical layer of HART protocol, and the software program of MSP430 microcontroller is introduced. The system fulfils all kinds of functions as well as the HART communication.
