摘要
本论文的内容为基于NDIR的CO浓度探测器研制的硬件部分,具体内容可分为CO浓度探测器的现状、发展趋势和分类,基于NDIR的CO浓度探测器的原理,探测器的硬件设计,基于实验室条件下探测器的制作,以及探测器的性能调试。
论文从CO浓度探测器的现状、发展趋势和分类开始,详细介绍了CO探测器的各个方面,探讨了研制CO浓度探测器的意义与基于NDIR的CO浓度探测器的实现原理。论文介绍了基于NDIR 的CO浓度探测器中的红外光源与红外探测器的选择,并详细介绍了红外光源与红外探测器的选择理由以及性能。基于NDIR的CO浓度探测器的核心器件为MIRL17-900红外光源与TPS2534红外探测器。在这两个核心器件的基础上,论文介绍了配套的光源调制,实验气室,后续放大滤波电路的设计与制作,以及扩展电路的设计。
论文中所制作的硬件部分均在实验室条件下完成,各个硬件在现有的制作条件下尽可能的达到理想效果。论文中还具体阐述了硬件制作过程和制作过程中的注意事项。制作的硬件系统经过测试与调试,根据实验中所阐述的方法制作出来的基于NDIR的CO浓度探测器符合实验要求,达到了预期目的。
基于NDIR的CO浓度探测器硬件部分研制的实现证明了在实验室条件下也可以研制出CO浓度探测器,并且在这个基础上可以继续完善,使之成为一个可以在实际生产生活中广泛应用的产品。

ABSTRACT
This paper based on the content of NDIR concentration of CO detector developed hardware, the concrete content can be divided into the concentration of CO detector's situation, development trend and classification based on the NDIR, the principle of concentration of CO detector, the probe's hardware design, based on the laboratory condition of production, and detector probe the performance test.
The concentration of CO detector papers from the current situation, development trend and classification start, introduces CO detector each aspect, discusses the significance of the concentration of CO detector developed based on NDIR with the realization of the principle of concentration of CO detector. This paper introduces the NDIR concentration of CO detector based on the infrared light source and infrared detector choice, and introduces the infrared light source and infrared detector reasons for choice and performance. Based on the NDIR concentration of CO detector for MIRL17 core device with infrared light TPS2534-900 infrared detectors. In these two core device basis, this paper introduces a matching lamp-house modulating, experimental gas chamber, the subsequent amplification filter circuit design and production, and expansion circuit design.
