摘要
从通风机运行风量和效率的自动调控、设备故障实时诊断预警、保护性停机倒机和远程集控4个技术层面进行了系统总体设计;更考虑了避免高寒地区潮湿气流在引压管网中结冻阻断信号。选用西门子S7-300系列PLC为下位机、工控机为上位机,采用WinCC组态软件,提高了煤矿生产自动化和信息化水平。经实际运行,系统安全可靠,监控精度高。
This paper discusses overall system design in view of following four technical aspects： automatic regulation of air volume and efficiency of ventilator,timely diagnosing and early-warning of equipment fault,protective ventilator inverting and halt,and remote centralized control.The system also considers the influence of moist air,which may be frozen to block signal,on pressure drain-device.The on-line monitoring system,consisting of S7-300 series PLC as slave computer,IPC as host computer,and WinCC configuration software,improves the automation and information level of the coal mine.Via actual operation,the system,with high accuracy,has been proved to be safe and reliable.
