摘　　要：　介绍了以MSP430型单片机为核心的智能涡街流量计转换电路的设计与开发,涡街传感器前置放大板送出的脉冲信号进行采集处理并送D/A转换模块进行标准4～40mA输出。重点对硬件电路设计、软件实现等内容进行了阐述。经现场考核运行表明,技术指标达到设计要求,工作可靠,解决了以往转换电路存在的功耗大、性能不稳定等问题。性能接近同类进口产品的水平,成本远低于同类型进口产品,具有广泛的市场前景。The design and development of the conversion circuit to an intelligent vortex flowmeter were introduced. The converter used MSP430 microcontroller as the main component, which collected, processed the pulse signal from the pre-amplified circuit and sent out 4～40 mA standard signal. The design of hardware circuit and implementation of software was stated. The result shows that the technology index has met the design requirement with the character of reliability, which solves the problem of the large wastage of power and low stability. Its performance can be comparable with that of the same import products. And its cost is much lower. It has a good prospect.
