以山西兰花同宝煤业某煤矿的实际应用为背景,设计了基于S7-300PLC为核心的空压机在线监测控制系统,实现了空气压缩机的实时监控、集中管理、故障报警及设备保护,解决了多台空压机联合运行时的稳定协调问题;考虑到变频工况下的谐波干扰,采取了抗干扰措施;采用WinCC组态软件设计了丰富友好的人机界面;系统具备空压机性能及状态评价功能,可及时做出评估并反馈给控制系统。
Taking the practical application of a certain coal mine in Tonghua coal mine of Shanxi orchid as the background, an on-line monitoring and control system for air compressor based on S7-300PLC was designed to realize the real-time monitoring, centralized management, fault alarm and equipment protection of air compressors, To solve the multi-air compressor joint operation of the stable coordination issues; taking into account the harmonics under the frequency of interference, taken anti-jamming measures; using WinCC configuration software designed a rich and friendly man-machine interface; system with air pressure Machine performance and status evaluation capabilities, can make timely assessment and feedback to the control system.
