基于MSP430的超声波管道流量计的设计

摘要

Fluid flow measurement in pipe is the common problem in industrial production.This paper introduces a kind of ultrasonic flowmeter based on MSP430 single chip microcomputer. This system uses a MSP430F1121A of TI company as the main control unit, uses the time-to-digital converter chip TDC-GP21 as the time chip, and use the nRF24L01 wireless transmission module, finally complete the data collection, processing, transmission and display. System working stability, measuring accurate, cost-effective, has a certain practical significance. The system work stable, accurate measurement, cost-effective, has a certain practical significance.%管道中液体流量测量是工业生产中的常见问题，本文介绍了一种基于MSP430单片机的超声波流量计。系统采用了TI公司的MSP430F1121A为主控单元，选用高精度时间数字转换芯片TDC-GP21作为计时芯片，并利用nRF24L01模块进行无线传输，最终完成数据的采集、处理、传送、显示。系统工作稳定、测量准确、性价比高，具有一定的现实意义。
