副井提升信号系统的PLC控制方案

可编程序控制器（ＰＬＣ）不仅因其控制功能强，体积小，操作简便，更重要的是，其响应速度快，故障率低，维护量小而在现代矿井中得到了广泛的应用，随着ＰＬＣ技术的不断发展，其性能价格比也逐渐降低。目前，很多矿井采用了可编程控制器来实现副井提升机的运输指挥，本...

Design of the PLC-based burner Control System

With consideration to the acid gas incinerator burned and the problems identified during its application, renovation program has been proposed. According to the new design, draught burners with automatic control system shall be used to eliminate problems encountered during application of original burner. In addition to implement automatic control of combustion processes, the new system may minimize labor intensity and enhance safety of facilities.
