基于CAN总线变电站综合自动化通信系统的研究

本文首先介绍了变电站综合自动化系统的分层结构以及目前在站内广泛使用的串行通讯总线的缺点；然后引入了CAN通讯总线，作为一种很有前途的现场总线，CAN总线通信相对于一般的串行通信总线，它的实时性，可靠性和灵活性的特点更加突出；在此基础上，本文介绍了CAN总线在变电站综合自动化系统的应用，并从硬件及软件方面详细的介绍了变电站综合自动化系统中通信管理机的研制。

STUDY OF SUBSTATION AUTOMATION COMMUNICATION SYSTEM BASED ON CAN BUS

Firstly,the paper introduces the layered structure of substation automation system and the disadvantages of the serial bus used generally nowadays inside the stations.Then the CAN Bus is introduced,the communication based on the CAN Bus which will face a beautiful future has better merits in expeditiousness?eliability and flexibility compared to general serial bus.Besides these,this paper gives a special research in the application of CAN Bus in substation automation system including the designing of communication system in hardware and software.
