探测灾后幸存生命的系统一直是国家以及各个地方救援队伍的必备设备,通过采用科学的方法,可以极大的提高救援的成功率。在本文中介绍了一种基于工控机的,按照CPCI规范而构建的声学生命探测系统,描述了该系统的基本组成和工作原理,并对系统的硬件和软件作了较为详细的说明。实际应用说明,该系统可很好的应用于生命探测领域。 Survival system to detect post-disaster survivors has always been an essential equipment for the rescue team at the national and local levels. By adopting a scientific approach, the success rate of rescue can be greatly improved. In this paper, an acoustic life detection system based on IPC is introduced, the basic composition and working principle of the system are described, and the hardware and software of the system are described in detail. The practical application shows that the system can be well applied to the field of life detection.
