一种光电检测装置的可靠性设计

摘要

为了解决一种红外光电检测装置出现的在不同光背景下的测量异常现象等,提高可靠性,通过分析对比检测装置和背景等因素,查找验证阈值范围.依此设计出随光背景变化的变阈值检测技术.最终通过实际测试和验证,光电检测装置适应环境能力强,可直接用于夜晚和日光下.%In order to solve the problem of measurement abnormality of an infrared photoelectric detection device in different light backgrounds and raise its reliability,such factors as detection device and background were analyzed and compared to find the range of its threshold values,so that the detection technique with variable thresholds changing with light background was designed.Finally,actual tests have verified that this photoelectric detection device was highly adaptive to the environment and could be used directly in the night and in the sunlight.
