学校、图书馆,研究所等单位,一般保安设施比较简陋,随着教学科研条件的改善及计算机的普及,原有保安设施已经变得不相适应。这里介绍一种经济而实用的防盗方法,即红外探照灯的应用。 红外探照灯有别于普通探照灯,后者是整个夜间都点亮,而前者唯有在人员入侵时才启动,合乎节省能源的要求。它是由被动式红外侦测器及高亮度的卤素探照灯组合而成。当有人员入侵进入被动式红外侦测器的监视范围时,侦测器输出一个启动信号,使高亮度的卤素探照灯通电并射 Schools, libraries, research institutes and other units generally have relatively poor security facilities. With the improvement of teaching and research conditions and the popularization of computers, the original security facilities have become incompatible. Here is an economical and practical anti-theft method, that is, the application of infrared searchlight. Unlike other searchlights, which are lit up throughout the night, the infrared searchlight is only activated when a person intrudes, saving energy. It is a combination of passive infrared detectors and high-brightness halogen searchlights. When a person intrudes into the passive infrared detector monitoring range, the detector outputs a start signal, so that high-brightness halogen searchlight power and shoot
