【Abstract】 The principle of passive infrared detection used for disaster relief in seismic site is described, and the design and test resuls of the HSY 1 infrared life detector are stated in detail. The detected distance and visual angle of the instrument are more 15m and 35° respectively, and the power loss is less than 12 V 50 mA DC. It is the first application of the infrared detection technique to the disaster relief in seismic site in China.更多还原
