摘要
设计了一套集音视频采集、环境数据采集于一体的机场导航站综合监控系统的前端采集装置。采用ARM处理器S3C2410和GO7007SB芯片设计了嵌入式音视频压缩主板,可将音视频数据采集、压缩、打包为MPEG4码流后,通过以太网上传到监控中心管理软件。环境采集卡采集的数据可以通过音视频采集主板实现透明传输,采用GM8125实现串口扩展后可接入5条RS485总线,同时采集上百个底层监测设备,具有较强灵活性和负载能力。
This paper designs a set of front-end acquisition device, which integrates the audio and video collection and environmental data collection together for the airport navigation-station monitoring system. The embedded audio and video compression motherboard adopts ARM processor, S3C2410 and GO7007SB chips. And then the audio and video data can be collected, compressed, and packed into MPEG4 data stream and be uploaded to the management software in the monitoring center by Ethernet. The data from the environmental collection card can finish the transparent transmission on the audio and video collection motherboard. The GM8125 can extend the serial ports for 5 RS485 buses and collect hundreds of monitoring devices, with strong flexibility and load capability.
