摘要
设计了基于S3C2410嵌入式处理器、AT2042双通道视频编码器和CDMA数据模块的无线视频监控终端。利用CDMA数据模块将低码率的次级通道压缩视频传输到监控中心,实现了远程实时监控;同时,将高码率高质量的基本通道压缩视频存储到移动硬盘或SD卡,以利于视频分析。并详细介绍了此无线视频监控终端的硬件结构和关键硬件接口电路的设计。
A wireless video surveillance device was designed, based on the embedded processor $3C2410, the 2-way video encoder chip AT2042 and CDMA wireless data module. In order to realize real-time remote surveillance, the low-bit-rate compressed video streams of the scaled channel were transported to the monitor center via CDMA wireless data module. Simuhaneously, the high-bit-rate compressed video with high image quality, produced by the base channel, was recorded on the mobile hard disk or SD card and was suit for video analysis. Hardware structure and the key interface circuit of the wireless video surveillance device were presented.
