PLC与变频器在井下带式输送机集控系统的应用研究

Research on Application of PLC and Frequency Converter in Underground Belt Conveyor

在生产煤炭的过程当中,因为煤炭的开采具有不均衡的特性,这使得井下带式的输送机会不定时的处于空载乃至轻载的工作状态,这将会大量的浪费电能。基于该原因,官地矿提出了一种基于PLC和变频器的井下带式输送机集控系统,这种系统可以实现带式输送机的智能调速。

In the process of producing coal, because the coal mining has unbalanced characteristics, which makes the underground belt con-veyor opportunities from time to time in the no-load and even light load of the working state, which will be a lot of waste of energy. For thisreason, Yanzi Mine proposed a PLC and inverter based on the underground belt conveyor centralized control system, this system can achievethe belt conveyor intelligent speed.
