摘　　要：该文提出一种无线可视对讲系统设计方案,系统采用了飞思卡尔i.MX21 ARM嵌入式芯片,结合嵌入式Linux技术、音视频编解码技术以及无线传输技术,使得该无线可视对讲系统具有比传统模拟系统占用传输带宽更窄、交互能力和控制能力更强、智能化程度更高等优点。Researched the situation of building intellectualized system, making use of currently popular wireless video transfers technology, design a new embedded visual door bell system based on the Freescale i. MX21 ARM embedded chips, and expounded the system structure and operating principle on the entirety. Introduce the design of software and hardware in outdoor and indoor unit. The visual wireless door bell system based on embedded which this paper described has much more interactive capability to control. The prospect of applies is very vastly.
