一种基于RS-485总线的多路温度数据采集系统设计

Design of Multi-channel Temperature Data Acquisition System Based on RS-485 Bus

介绍一种基于RS 4 85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 4 85总线上构成RS 4 85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 。

A multi channel temperature data acquisition system has been introduced 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.
