摘要
介绍了双波段可燃气体探测技术 ,设计了探测装置。通过分析探测原理 ,对信号处理电路进行了改进。结果表明 ,双波段技术减小了环境因素的影响 ,非可燃气体对光线的阻挡 ,不产生误报。改进后的电路系统提高了信号稳定性和灵敏度。
This paper presents the technology of detecting flammable gases with dual infrared wavelength lights and the design of the gas detection facility. The circuit is improved by analyzing the detecting principle. The results show that the environmental influence is reduced and alarms would not respond to non flammable gases. The reliability and sensitivity of the circuit system are improved as well.
