【摘要】 对中小规模工程中基于PC机的实时数据采集平台进行了研究,并论述了在MATLAB/xPCTarget环境下,利用CMEX(编译链接)S函数(S函数为系统函数的简称)进行I/O自定义模块的研发方法,并举例阐述了此数据采集方案的可行性.利用MATLAB/xPCTarget硬件平台,可以大大节约硬件成本,且易于实现远程控制,为xPCTarget在实时测控工程中的应用提供了有益的探索和参考.更多还原

【Abstract】 In this study,a PC-based real-time data acquisition platform is postulated for small-and medium-size engineering projects.Under the MATLAB/xPCTargetTM environment,a development method for user-defined I/O module is completed using C MEX S function.Furthermore,the data acquisition feasibility is elaborated based on an example.In this manner,this platform possesses such advantages as saving of hardware cost and ease of remote control.To this end,this approach sets a reference to xPCTarget-enabled real-time monitoring systems.更多还原
