    • Disclosed is a security monitoring method determining whether a trespasser is detected and a position of the trespasser in a set security space and monitoring sound generated at the position of the trespasser by using an acoustic image generated from acoustic signals generated by an acoustic generating device and an acoustic measuring device in an array type. An exemplary embodiment of the present disclosure provides a security monitoring system including: an acoustic generating device that generates acoustic signals; a plurality of acoustic measuring devices that receive the acoustic signals; and an acoustic image processing device that generates an acoustic image using a beamforming algorithm from the acoustic signals received in the plurality of acoustic measuring devices and determines a position of a trespasser by comparing the acoustic image after the trespasser is detected with the acoustic image before the trespasser is detected.
    • 公开了一种安全监控方法,其通过使用由声发生装置产生的声信号产生的声像来确定是否检测到侵入者以及在设定的安全空间中的侵入者的位置以及在侵入者的位置处产生的监听声音, 阵列式声学测量装置。 本公开的示例性实施例提供了一种安全监控系统,包括:产生声信号的声产生装置; 多个声学测量装置,其接收声学信号; 以及声学图像处理装置,其使用来自在所述多个声学测量装置中接收的声学信号的波束形成算法生成声学图像,并且通过将侵入侵入者之后的声学图像与所述声学图像进行比较来确定侵入者的位置, 检测到侵入者。
