制氮装置无人值守远程监控系统

Unattended Remote Monitoring System for Nitrogen Generator

制氮装置是应用于煤矿井下防火灭火的核心设备。在煤矿智能化建设的背景下,面对传统矿用制氮装置自动化程度不高以及难以集中监控的困境,开发了一款兼顾自动化运行要求和智能监测控制需求的制氮装置无人值守远程监控系统。利用PLC对制氮装置进行数据采集和全自动控制,采用组态软件开发高效直观的HMI/SCADA系统平台,对关键数据信息进行统计分析处理以实现系统的精准协调控制和故障自诊断功能。工业试验表明,本系统实现了对制氮装置自动化运行状态的远程实时监测和集中管理控制,最大程度上降低了现场监管操作人员成本,并减少了因误操作而可能导致的生产事故。对于提高煤矿安全生产调度和风险智能化管控水平具有重要意义。

Nitrogen generator is the core equipment used for fire prevention and extinguishing in coal mines.Under the background of the intelligent construction of coal mines,in the face of the dilemma of low automation and difficulty in centralized monitoring of the traditional mine-used nitrogen generator,an unattended remote monitoring system of nitrogen generator which takes into account the requirements of automatic operation and intelligent monitoring and control is developed.The PLC is used for data acquisition and automatic control of the nitrogen generator.The configuration software is used to develop an efficient and intuitive HMI/SCADA system platform.The statistical analysis and processing of the key data information can realize the precise coordinated control and falut self diagnosis function.Industrial tests show that this system can realize the remote real-time monitoring and centralized management and control of the automatic operation state of the nitrogen generator,which reduces the operator cost of on-site supervision to the greatest extent,and reduce the possible production accidents caused by misoperation.It is of great significance for improving coal mine safety production scheduling and intelligent risk management and control.
