摘　　要：设计了一种基于嵌入式平台的声音信号采集和视频采集的软、硬件系统。硬件设计采用模块分层思想,将整个硬件系统拆分成核心板和底板两部分。软件设计采用多线程编程方法,实现信号连续采集和实时显示。对硬件系统设计、声音信号采集和视频采集做了详细的介绍,系统对于多传感器网络嵌入式平台的设计和应用具有一定的意义。Designs of software and hardware system for acquiring acoustical signal and video capture based on embedded platforms is introduced. Adopting module hierarchy idea,the hardware system is divided into core-board and base plate. The software design uses multithreading programming technique which can realize continuous signal collection and real-time display. Design of hardware system,acoustical signal and video signal acquisition are introduced in detail. It has certain meaning for design and application of multisensor networks embedded platforms.
