Design and Implementation of Life Detect and Orientation Measurement System through Sound and Video Integration

文章论述了该声光一体生命搜索与定位探测仪器设计与实现方法。通过红外摄像前向通道和水平通道采集入视频信号,指向性驻极体麦克风监视受灾环境的声音,送入A/D进行转换,所得数字音频和视频送入DSP进行所需处理,由FIFO缓冲经D/A转换,分别送到小型液晶显示器和耳机进行监视和监听,从而帮助营救人员进行救援工作。该方案具有良好的灵活性、可升级性和高效性的特点。

This paper briefly introduces the design and implementation of life detect and orientation measurement system.It collects video and sound signal by infrared pickup camera and microphone.The analog signals are transmitted into A/D Converter and enter into DSP handled with specified arithmetic,then by FIFO and A/D,in the end the analog video and sound signal are transmitted into LCD screen and microphone helping succor save those who are hit by a natural earthquake calamity.The scheme has the properties that they are of great flexible and expandable and efficient.
