【摘要】 根据 lAmbert-Beer 定律和气体对红外线的选择性吸收规律,提出了利用红外法检测汽车尾气,采用电调制红外光源的新型非分光红外气体传感器,节省了传统方法中的机械调制部件;同时采用高精度干涉滤光片一体化热释电红外传感器及单光束双波长技术。本文描述 ZIGBEE 技术,并应用于无线检测系统中,是一种新型应用。更多还原

【Abstract】 According to the Lambert-Beer law and the fact that gas could absorb infrared ray selectively,the method of the infrared examination automobile exhaust is proposed,the new non-dispersed infrared gas sen- sor using electro eliminates modulation infrared photosource is used,the mechanical modulator that used in traditional method;while a high-precision interference filter infrared sensor and dual-wavelength single- beam technology is used.The thesis describes the ZIGBEE technology that applies to wireless detecting sys- tem.This kind of model application is the newest.更多还原
