摘　　要：针对传统的电子天平测数据记录繁琐,测量数据的可操作性差,设计一种基于LabVIEW的高精度电子分析天平管理系统,介绍了利用超低功耗单片机MSP430F449为核心处理器,CS5532为AD转换器的高精度电子分析天平的硬件结构及工作原理,详细阐述了LabVIEW通过VISA通信的软件流程和部分模块结构的实现方法,并对系统的上位机软件安全性做了简要介绍。实测结果表明,该管理系统安全可靠,操作简便,成本低廉,有很强的数据处理能力。For the trouble data record process and poor data interoperability in traditional balance measurement equipment,this paper designed a high accuracy electronic analytical balance manage system based on LabVIEW,which was equipped with super low power MSP430F449 for information processing and CS5532 for A/D convertion.The software process and implemetation method in which LabVIEW controlled the instrument by VISA was elaborated,and the design of some block was briefly introduced.The manage system is proved to be accurate and reliable,and easy to operate with strong data processing ability.
