摘要

研制了一套开关柜在线监测系统

重点介绍此系统中通讯单元的设计。通讯作为沟通设备层开关柜在线监测装置（下位机）和管理主机（上位机）的桥梁起着重要作用。为了达到有效进行分布式监测的目的并且综合考虑装置成本、实现难易程度、开发周期等因素

提出采用485总线和CAN总线相结合的双总线的通讯方案

CAN总线完成故障数据的主动上传从而保证其实时性

而RS-485总线负责传送上位机请求数据

保证了通讯的高效性和实时性。

Abstract

An on-line monitoring system for switchgear is developed

and the communication unit is mainly introduced.As a connection between on-line monitor and managed computer

communication plays an important role in the system.In order to monitor distributedly

considering the device cost

realizing complexity and development period

the dual-field-bus（485 field-bus and CAN field-bus） is adopted as the communication scheme.The failure data is uploaded by CAN field-bus

and the request data is transmitted by RS-485 field-bus.It proved that the communication unit to be efficient and real-time.
