摘　　要：为满足工业远程网络监控的快速发展需求,设计一种基于网际组态软件WebAccess的远程异构式网络监控系统。首先以分布式控制为指导思想,确定自下而上的分层控制方案,以RS 485和ProfiBus现场总线连接底层设备,以MCGS和WinCC构成中间控制层,最后以WebAccess完成远程控制。采用中间件技术实现不同组态软件之间的数据交互。系统综合调试结果显示,该系统集成方案合理,实现了双向远程数据信息的交互,系统整体满足设计要求,设计思路有较强的新颖性和实用性。To satisfy the demands of rapid development in industrial remote network monitoring,the remote heterogeneous network monitoring system based on configuration software WebAccess was designed. Taking distributed control as guiding ideolo?gy,the bottom?up hierarchical control scheme is confirmed. The basic layer equipments are connected with RS 485 and ProfiBus field?bus. The intermediate control layer is constituted with MCGS and WinCC,and remote control is accomplished by WebAc?cess. The middleware technology is adopted to achieve data interaction between different configuration software. System compre?hensive debugging results show that this integration scheme is reasonable. The interaction of bi?directional remote data informa?tion was achieved. The entire system satisfies the design demands,and the design idea has strong novelty and practicality.
