基于双CPU架构的Modbus总线仪表开放式采集实验装置设计
|
摘要
Modbus总线型仪表在工业领域有着广泛的应用,相应集中数据采集装置是高效获取数据的关键.基于双CPU架构设计了数据采集实验装置,结合双口RAM的应用,开辟了数据交换通道,使两CPU能够协调工作.软件设计上采用结构体设计方法,使软件架构更为清晰合理.上位机配置软件的设计增强了系统的开放性,为教学和科研提供了有力的辅助工具.
The instruments with Modbus bus are widely used in industrial field,and the corresponding centralized data acquisition device is the key to obtain the field data efficiently.The data acquisition experimental device is designed based on dual CPU architecture.Combining with the application of dual-port RAM,it opens up a data exchange channel,so that the two CPUs can work harmoniously.The structure design method is adopted in software design to make the software architecture more clear and reasonable.The design of PC configuration software enhances the openness of the system.That provides a powerful auxiliary tool for teaching and research.
