摘　　要：分析了煤矿监测监控系统的现状,提出了矿井多媒体综合业务数字网(MISDN),并对其网络结构进行了分析,提出采用本质安全型宽带工业以太网组建MISDN的网络基础架构,关键设备路由器采用32位RISC单片机S3C4510B实现,井下智能分站以Rabbit2000为核心实现.MISDN适合于环境恶劣、人员设备分散、有特殊安全要求等特点的煤矿,所有与安全和生产有关的煤矿监测监控数据、语音、视频等各种信息都在MISDN上传输,包括自动化系统中的控制信息,加上智能化决策及支持技术,从而建立起一个数字化企业.After explanation of video monitor system in coal mine, Multimedia Integrated Services Digital Network (MISDN) is brought as well as the configuration is discussed and broadband industrial Ethernet is used for network infrustrucure of MISDN. In MISDN, 32 bit RISC singlechip computer is being used to design key device router, and Rabbit2000 for intelligent substation in coal mine.MISDN is suitable for coal mine with characteristics, such as the bad environment, personnel's equipment dispersing, special safe request etc. All the kinds of message, including data(include the control information in the automated system), audio and video with safety and production, can be transmitted at MISDN. In addition, intelligent decision support technology also be used, so digitilized enterprise is set up.
