摘要
研究并实现了电力负荷监控系统中通信规约及设备的动态兼容问题.利用面向对象的观点,提出信道与规约独立、数据存储标准化等设计思想,将信道控制逻辑、通信规约等看作独立的对象从系统中划分出来,建立了通信规约插件模型.在组件内部通过定义数据结构与相关函数,实现了规约识别、规约组帧、规约帧解释等相关的任务,并进行了软件实现.实践证明,规约插件的建立使得系统可以灵活地配置无线电台、GPRS、光纤、电话等各种信道,并动态兼容不同厂家、不同型号的终端采集设备,为电力负荷监控系统的稳定高效运行提供了良好的解决方案.
The compatibility of the equipments and communication protocols in electric power load monitoring and control systems was studied. From the viewpoint of object-oriented theory, the thinking of the communication channels and the protocols independence and the data structure standardization are proposed, and the communication protocol plug-ins models are set up which separate the channel control logic and the protocols from the system. Through designing the data structure and the functions in the modules, the protocols identifying, frames composing and decomposing are realized, and the software is successfully developed. Practice indicates that with the plug-ins models, broadcasting, GPRS （general packet radio service）, FDDI （fiber distributed data interface） and other channels can be conveniently configured. The different remote terminal units from different manufacturers can be dynamically compatible. Thus a good solution for electric power monitoring and control system is provided.
