根据硫酸生产线的控制要求,设计了一套基于西门子SIMATIC PCS7的硫酸生产线的DCS控制系统,构建了由工业以太网(Ethernet)、现场总线(PROFIBUS-DP)组成的两层管控一体化网络。并对控制系统的硬件组态、网络配置、自动化程序设计以及监控界面组态等方面进行了研究,实现了对硫酸生产各工艺流程测点、设备运行状况的集中监测和整生产的管控一体化。项目投入试运行后,系统运行稳定,达到了预期设计的目标。
According to the control requirements of sulfuric acid production line, a DCS control system based on Siemens SIMATIC PCS7 sulfuric acid production line was designed and a two-layer integrated control network composed of industrial Ethernet (Ethernet) and field bus (PROFIBUS-DP) was constructed. And the control system hardware configuration, network configuration, automated program design and monitoring interface configuration and other aspects of the study, to achieve the sulfuric acid production process points, the centralized monitoring of equipment operation and the integration of the entire production control . After the project is put into trial operation, the system runs stably and achieves the expected design goal.
