Chinese Abstract

空气中二氧化碳浓度的测量在工业、农业、医学、卫生、环境保护和其它许多领域都有非常重要的意义。目前市售的二氧化碳测量仪表大都属于分析仪表,它们机理复杂,价格很高,难以得到广泛使用,因此亟需开发一种精度满足要求、价格较低的二氧化碳测量仪器。本研究给出了用红外传感器和高性能微处理器组成的二氧化碳测试仪的工作原理和简化仪表结构的设计思路,讨论了提高仪表灵敏度和消除误差的方法。实验结果表明,利用这种技术可以制造廉价的气体成分分析仪表。

English Abstract

The measurement of the concentration of CO2 in air is very important in industry, agriculture, medicine, hygiene, environmental protection and many other fields. But most instruments used or available in the market for CO2 measurement are analysis instruments with very complicated mechanism and high prices thus limiting their applications. The development of the low-price instrument to measure the concentration of CO2 in air is therefore urgent. The paper discusses the working principle and the structure of the simple infrared CO2 monitor based on the infrared technique and an advanced microprocessor. The principle to simplify the hardware of the monitor and to improve its sensitivity and accuracy in the measurement is illustrated. The experimental results have shown that the technique can be adopted to produce the gas composition analyzer at low cost.
