将Profibus-DP现场总线应用于煤矿空压机组监控系统中。西门子S7-300系列CPU315-2DP为主站,通过Profibus-DP总线建立了主站与变频器、西门子S7-200系列224和226控制器、2套Fx2N三菱控制器和2套ET200M DP远程扩展I/O从站共计7个DP从站的通讯,实现了数据实时传输的要求。利用工控组态软件WinCC和WinCCflexible开发了上位机和触摸屏监控系统,上位机与主站通过工业以太网通讯。实现了空压机组及其冷却水循环系统的集中监视管理和分散控制。
The Profibus-DP field bus used in coal mine air compressor monitoring system. Siemens S7-300 series CPU315-2DP as the main station, through the Profibus-DP bus established the master and inverter, Siemens S7-200 series 224 and 226 controllers, 2 Fx2N Mitsubishi controllers and 2 sets of ET200M DP remote expansion I / O Slave A total of seven DP slave communications, to achieve real-time data transmission requirements. The use of industrial control configuration software WinCC and WinCCflexible developed PC and touch screen monitoring system, the host computer and the master through Industrial Ethernet communication. The centralized monitoring management and decentralized control of the air compressor unit and its cooling water circulation system are realized.
