针对通用组态软件价格昂贵,其通用性对于工业现场的具体应用场合存在冗余造成资源浪费的现状,提出了基于OPC技术的矿井粉尘浓度监控系统。该系统由硬件和软件2部分组成,以Visual Basic为上位机开发平台,以S7-200系列PLC为控制器实现系统功能。仿真结果表明系统成本低、可靠性强,可满足对粉尘浓度的实时监测的要求。
In view of the fact that the general configuration software is expensive and its versatility has a waste of resources because of the redundancy in the industrial field, a monitoring system for mine dust concentration based on OPC technology is proposed. The system consists of hardware and software 2 parts, with Visual Basic as PC development platform, S7-200 series PLC as the controller to achieve system functions. The simulation results show that the system has low cost and high reliability, which can meet the real-time monitoring requirements of dust concentration.
