摘要

针对现有避难硐室供氧系统大多采用多级防护体系,各级供氧系统相互独立,系统之间无法自动切换而不能持续稳定供氧等问题,设计了一套基于PLC和PID控制技术的避难硐室自动供氧系统。该系统通过环形光纤系统将多级供氧系统和硐室环境参数监控系统集为一体,基于实时检测的环境参数,利用PLC和PID控制技术,实现了各级供氧系统之间的智能化调节和井下硐室的自动连续供氧,并能在某一级供氧系统出现故障时自动切换至下一级供氧系统,从而提高了避难硐室供氧的稳定性和安全性。现场测试结果验证了该系统的可靠性。
        In view of problem that most of existing oxygen supply systems of refuge chamber applied multistage protection system,and oxygen supply subsystems are independent of each other and cannot automatically switch among them,which causes the oxygen supply unstable,an automatic oxygen supply system of refuge chamber based on PLC and PID monitoring technology was designed.The system integrates multistage oxygen supply systems and environment parameters monitoring system through loop optical fiber system.Based on the detected environment parameters in real-time,and uses PLC and PID monitoring technology,the system can realize intelligent adjustment between all levels of oxygen supply system and automatic continuous supply oxygen of underground refuge chamber,and can automatically switch to the next level of oxygen supply system when a certain level of oxygen supply system happens failure,which improves stability and safety of the oxygen supply of refuge chamber.The site test results verify reliability of the system.
