The underground nitrogen production device is an important equipment for fire prevention and control in coal mines.With the rapid construction of intelligent coal mines,multiple underground nitrogen production devices face difficulties in centralized monitoring,querying records,and viewing reports.A PLC based centralized monitoring system for underground nitrogen production devices was designed,and the structural composition and control principle of the underground nitrogen production device were explained.The overall scheme design,hardware design,and software design of the centralized monitoring system were gradually carried out.On-site experiments showed that this system achieved centralized monitoring of multiple nitrogen production devices underground on the operating platform,effectively reducing the cost of on-site supervision equipment personnel,reducing accidents caused by misoperation,and improving the level of automation control.
