采用分布式网络技术对大型现代化国际机场灯光设备进行监视、控制和管理 ,这是当前机场自动化领域的重要发展方向之一 .为了解决整个灯光监控系统的可靠性、可诊断性和实时性 ,充分采用了通信、电子和网络等相关技术。详细介绍了一套基于两层计算机网络的分布冗余式综合监控系统设计方案 .下层网络为现场总线网络 ,主要采用CAN总线 ;上层网络是采用TCP IP协议的局域网 ,包括大型数据库、监控机、工控机以及交换机等 .设计方案已得到多次成功的应用
The use of distributed network technology for large modern airport lighting equipment surveillance, control and management, which is the current airport automation one of the important development directions.In order to solve the reliability of the lighting monitoring system, diagnostic and real-time, full Using communications, electronics and networking technologies. This paper introduces in detail a set of design scheme of distributed redundancy integrated monitoring system based on two layers of computer networks.The lower layer network is the field bus network which mainly adopts the CAN bus.The upper layer network is a local area network which adopts TCP IP protocol including large database, IPC and switches, etc .. The design has been successfully applied many times
