摘要:
封闭空间尤其是高校运动场馆、图书馆等人员密集场所,常因通风不足导致 CO2 浓度超标,既危害人体身心健康,也会降低活动体验与学习质量。为实现封闭空间 CO2 浓度的精准、实时监测,构建了一套基于非分散红外( NDIR )技术的传感系统,从硬件结构设计与信号处理算法 2 个层面进行协同优化,提升了封闭空间 CO2 传感系统的测量性能和工程适用性。实验结果表明,该系统对封闭空间内 CO2 浓度的实时监测预警能力显著提升,有效保护了封闭空间内人员的身心健康。
Abstract:
Enclosed spaces , especially crowded areas such as university sports venues and libraries , often experience excessive CO2 concentrations due to insufficient ventilation , which not only endangers people ’ s physical and mental health , but also diminishes the quality of activities and learning.To achieve accurate and real-time monitoring of CO2 levels in such environments , a sensing system based on Non-Dispersive Infrared ( NDIR ) technology is developed.The system incorporates synergistic optimizations at both the hardware architecture design and signal processing algorithm levels , thereby enhancing its measurement performance and practical applicability for CO2 sensing in enclosed spaces.Experimental results show that the system significantly improves the capability for the real-time monitoring and early warning for CO2 concentrations in enclosed spaces , effectively safeguarding the physical and mental health of occupants in enclosed spaces.
