基于C-MBUS总线的数据采集系统设计与实现

Design and realization of the data acquisition system based on C-MBUS

介绍了一种基于MSP430单片机的数据采集系统的设计与实现。该系统以TI公司的16位FLASH型MSP430系列单片机为核心,以根据韦根德效应制成的零功耗磁敏传感器作为采集前端,选用C-MBUS总线进行数据传输,适用于远传抄表的数据采集。具体阐述了该系统的工作原理、硬件电路设计和软件实现．

This article primarily introduces how to design and implement a new ultra-low power consumption data acquisition system using Texas Instruments Incorporated MSP430 Flash series microcontroller. To be suitable to the remote automatic meter-reading, the system used a zero Wastage magnetic sensor as the acquisition forepart, Chinese Meter bus act as data transmitted module. The operational principle, the general designing, hardware circuit, software flow chart and the main programming frame are provided detail by detail in the paper.
