摘要
为了Modbus现场总线通信协议在一种流量计上的实现,给出了该实现的第一步——原型机搭建的具体过程。系统采用了AVR单片机和RS-485通信总线,采用C语言进行开发,以软件工程所定义的开发流程,从需求分析、概要设计、详细设计和维护等方面对系统地实现进行了详细的描述。
In order to the implementation of Modbus fieldbus communication protocol on a kind of flow meter and gives the de tailed process of build a prototype board,which is the first step of the implementation.The system uses AVR MCU and RS-485 communication bus.The C programming language is used for software develop.As software engineering defined,the paper de scribes the development process in needs analysis,summary of design,detailed design and maintenance.
