一种基于RS-485总线的多路温度数据采集系统设计

摘要

介绍一种基于RS-485总线的温度数据采集系统，应用于混凝土施工控制中。数据采集模块挂接在RS-485总线上构成RS-485总线网络，PC机与其进行数据通信。系统实现了对工业现场多路温度数据的采集、管理、显示与打印等功能。软件设计采用面向对象分析设计技术——Booch方法设计了项目类、图形类、工具类和数据类等，使系统模块化好，通用性强。%A multi-channel temperature data acquisition system has beenintroduced for the control of concrete construction.The data acquisition modules are connected on the RS-485 bus to form a RS-485 network,and data communication between PC and the modules is presented.The system implements the acquisition,management，displaying and printing of the multi-channel temperature data on the industry site.The item class,graphics class,tool class and data class have been designed using object-oriented analysis and design technique —— Booch method,so that the system has better modularity and universality.
