【摘要】 针对移动目标的距离检测问题，提出了一种红外探测器与超声波传感器互补使用的距离测量方法。组合使用2种不同类型的传感器，实现了20 m范围内移动目标检测，使用红外探测器敏感较远目标并测量距离，使用超声波传感器实现近距离测量，并通过物联网模块上传入侵信息。测量结果表明误差约为3.2%,对侵扰检测等应用场景具有参考意义。更多还原

【Abstract】 According to the problem of detecting moving targets, a distance measurement method using infrared detectors and ultrasonic sensors complementary was proposed.This method combined the use of two types of sensors to achieve the detection of moving targets within a range of 20 meters.Infrared detectors were used to detect distant intrusion targets and measure the distance, ultrasonic sensors were used to achieve close-range measurement, and intrusion information was uploaded through the Internet of Things module.Experimental results show that the distance measurement error of this method is about 3.2%,and has reference significance for application scenarios such as intrusion detection.更多还原
