【摘要】 随着国民经济的进一步发展，迫切要求提高电力系统自动化的水平。在整个电力系统综合自动化系统中，电力通信扮演着至关重要的角色，本文就研究了位于电力通信中底层的现场智能控制装置和远方调度以及其和现场监控的通信，设计了实现这级通信的装置—电力自动化通信管理机。 首先，论文探讨了电力通信的现状，论述了开展论文工作的必要性，讨论了通信管理机所实现的功能，规约转换和通信管理。然后，给出了电力自动化通信管理机的设计方案，介绍了论文所采用的硬件基于C32数字信号处理器(DSP)和软件以实时操作系统(ROTS)为平台的方案，并论证其可行性。在随后的章节里，详细讨论了实现这个方案的硬件和软件细节，给出了串口通信扩展，液晶接口等硬件电路，以及RTOS，通信协议等软件模块。同时也给出了论文实验结果以及相应的分析。在最后，对论文工作存在的问题和以后可以改进的工作做一论述。更多还原

【Abstract】 With the further development of the national economy, the demand to improve the automation level of power system is greatly needed. In the whole power automation system, power communication plays an important role. As a part of power communication, the communications of the Integrated Electronic Devices( IEDS) in the field with the local supervisory and the remote management center is discussed in the paper. To realize this, design and implementation of Management Machine of Power Communication is set forth in the paper.Firstly, the present condition of the power communication is discussed. At the same time, the necessity of the paper, and the function of the Management Machine of Power Communication, Protocol conversion and Communication Management, are also presented. Secondly, the scheme of the Management Machine of Power Communication, whose hardware architecture is based on C32 Digital Signal Processor (DSP) and software is based on Real Time Operation System (RTOS), is discussed. And also the possibility of realization of the scheme is demonstrated. In the following parts, the detailed implementations of hardware and software, such as serial communication extension, the LCD’s interface with DSP, RTOS module, Protocol Conversion module, etc. are presented. After that, the result of experiment and the corresponding analysis are given. At last some problem of the paper and some followed work which can be done are summarized.更多还原
