摘要
介绍了一种小电阻测量仪的设计方法,包括系统的硬件和软件设计。该仪器以MSP430F149单片机作为控制核心,具有数据存储、与PC通信以及LCD显示等功能。该小电阻测量仪具有低功耗、高精度、携带方便等特点,特别适于在工作现场的测量。在某些场合下可通过SM卡来实现数据的保存。
This paper presents the design of a portable measuring instrument for littie resistance,including the design of hardware and software. This instrument has used MSP430F149 as the core of the system,and it can complete data memorizing,communication with PC, LCD displaying and other functions. Lower power-consuming, high accuracy and portable are all its peculiarities. So in particular it can he properly used in work field besides in the lab. In some conditions the data sampled can he saved in the SM card.
