提出了以西门子S7-300 PLC为核心,PROFIBUS-DP现场总线为主干,用WinCC作为上位机监控软件,把主通风机系统所包含的高压进线柜、换向柜、出线柜、稀油站、工作风门和实验风门以及软启动柜进行集中监控,同时上位机还能对风机的温度、振动、风压、CD和CH4浓度以及其他分散设备的参数进行实时监测,系统满足《煤矿安全规程》规定。 Proposed Siemens S7-300 PLC as the core, PROFIBUS-DP fieldbus as the backbone, with WinCC as the host computer monitoring software, the main fan system consists of high-voltage incoming cabinet, reversing cabinets, outlet cabinets, thin oil stations , Working air door and experimental air door as well as soft start cabinet for centralized monitoring. At the same time, the host computer can also monitor the temperature, vibration, wind pressure, CD and CH4 concentration and other distributed equipment parameters of the fan in real time. The system meets the requirements of “Coal Mine Safety Regulations” Provisions.
