【摘要】 为满足计算机自动数据采集实验课程教学,设计了一套基于VB6.0的开放式数据采集实验系统。系统以检测变送环节为源头,采用标准二线制接线方式,并集成USB、RS-485等多种总线模式,构建完整的多模式数据采集系统。基于开放式安装底板,学生可自行设计、自主接线、自编程序,构建多样的数据采集系统,有效提升学生的学习兴趣和实践能力。以标准的温度变送器和某系列数据采集模块为例,给出了系统软硬件的实现过程。更多还原

【Abstract】 To meet the teaching of PC-based automatic testing experiment course, a set of open data acquisition experimental system based on VB6.0 was designed. the detection and transmission links were took as the source, standard two-wire wiring was adopted, and multiple bus modes such as USB, RS-485 and so on were integrated to construct a complete multi-mode data acquisition system. Based on an open mounting based on plate,students can design, connect, and program themselves, and construct a variety of data acquisition systems to effectively improve the students’ learning interest and practical ability. Taking the standard temperature transmitter and a series of data acquisition modules as an example, the implementation process of the system hardware and software was given.更多还原
