循环式远动规约数据采集方法设计

摘要

For the issues of data acquisition existed in substation automation,study the data collection method of cycle distance transmis-sion. First,describe the CDT basic knowledge including frame structure,information word,calibration method;secondly,on the basis of studying the basic communication model,design acquisition system structure;then,research data acquisition control including means com-munication of MSComm control,CommEvent attribute,MSComm attribute set;finally,research data reception method,according to the full frame receiving process to design data receiving process with process design language. Use this study contents to design the power grid data acquisition system,it meets the needs of enterprises modern management and can achieve the standardization of data manage-ment,improves efficiency and economic benefits.%　　针对变电所自动化中数据采集存在的问题，文中对循环式远动规约数据采集方法进行研究。首先，阐述了CDT基本知识，包括帧结构、信息字、校验方法等；接着，在研究基本通信模型的基础上，设计了采集系统结构；然后，研究数据采集控件，包括MSComm控件的通讯方式、CommEvent属性、MSComm属性设置；最后，研究数据接收方法，根据完整的帧接收流程，用过程设计语言设计了数据接收处理流程。运用文中的研究内容设计电网数据采集系统，符合企业现代化管理的需要，可以实现数据的标准化管理，提高工作效率和经济效益。
