摘　　要：红外电路故障检测仪作为一种高效的非接触式电路板故障检测手段得到广泛应用,但庞大的系统成为继续推广的一道屏障。针对这一问题,本文以S3C6410为核心处理器、Tvp5150为视频解码器以及红外热像头模块,构建了高度集成的嵌入式实时视频采集平台,在此基础上完成了便携式红外电路故障检测仪的设计。该设计具有体积小、功耗低、成本低、安全性高、稳定性高、应用灵活等特点,极好地满足了便携式视频采集设备的需求。提出了一种适用于该检测系统的视频采集驱动设计方案,在Linux2.6.28版本内核下,以Linux下处理视频设备的最新标准——V4L2为基准完成驱动程序编写。实验证明该方案成功实现了视频数据的采集。As a highly efficient non-contact way of detecting PCB faults,an infrared detection tester has been widely applied.However,the huge size of the current system has remained a headache for this technology＇s further popularization and application.To solve this problem,a highly integrated embedded real time image capturing platform which consists of s3c6410 as a kernel processor and tvp5150 chip as a video decoder and an infrared camera module is established.And a portable infrared detection tester is developed based on this platform.This scheme has the characteristics of small size,low power,low cost,safety,stability and flexible application,which well meets the requirements for portable video capturing devices.A driver design of video capturing for this infrared detection tester is proposed.The procedure of developing the Linux video capture is elaborated based on the standard of V4L2 which is the new framework for video device driver development.And the feasibility has been proved by experiments.
