摘　　要：供氧系统是避难硐室防护系统的重要组成部分,为提高避难硐室供氧系统的稳定性和安全可靠性,设计了基于PLC的自备供氧系统。该系统采用高压氧气瓶提供氧气,利用PLC自动控制技术,将避难硐室内氧气浓度自动控制在18.5%～23.0%之间,实现了避难硐室的连续供氧。The oxygen supply system is an important part of the protection-system of the refuge chmlaber. In order to improve the stability, safety and reliability of the oxygen supply system of the refuge chamber, the self-contained oxygen supply system was designed base on PLC. High pressure oxygen bottle was used to provide oxygen for the system. The oxygen density in the refuge chamber was automatically controlled within 18.5% - 23.0% by using PLC control technology, thus the continuous oxygen supply in the refuge chamber was realized.
