文档介绍：基于 MSP43 0 单片机的气体涡轮流量计设计摘要: 流量测量在工业生产、能源计量、环境保护、交通运输、生物技术、军事工程和科学研究等领域占据重要位置,因此,流量测量仪表的研究和开发应用有着深远的意义。涡轮流量计是流量测量仪表中不可缺少的一员,随着现代计算机技术的发展而不断发展和完善。按照模块化设计方法,将系统硬件部分分为不同的功能模块分别进行设计。本着小型化、智能化的原则,设计中采用 TI公司的高性能、微功耗 MSP430F147 单片机作为控制核心,实现了气体流量的实时补偿,提高了仪表的测量精度。在外围器件选型和软件编制过程中进行低功耗设计,极大地降低了仪表的功耗,使流量计具有较高的可靠性。通讯方面可以选择 RS-485 和HART 总线方式,方便了仪表与上位机的连接。 LCD 显示和键盘方便了用户的操作。软件部分采用了模块化的编程,介绍了各模块的实现方法,最后组合起来进行调试。通过试验,本系统初步达到了流量计量的目的,系统的结构合理,功能完善,硬件和软件设计达到了预期要求。关键词:涡轮流量计; MSP430 ;流量补偿; HART 总线;温压传感器 D esign of gas turbing flowmeter based on the MSP 430 abstract A bstract : Flow measurement occupy an important position in industrial production , energymeasures , environmental , protection,transportation,biotechnology,en gineering,military science and other ,there are far-reaching significance research and development applications in flow measurement Flowmeter is an indispensable instrument,which are continuously developed and improved with the development of puter technology. System hardware were designed through divided into different functional modules. Through use of TI's MSP430F147 microcontroller as the core, make the pensation in real-time and improve the accuracy of the measurement. In the course of design, reduce the power consumption of the instrument greatly, and make the flowmeter have a high bouth has R485 and the HART bus, so connect to PC very conveniently. User can operate the turbine flowmeter easily, through LCD display and keyboard. Introducting the method of the module that how to Implementat bination of debugging experiments result has showed that the system has the features of rational structure and perfect function.
