中文摘要：

挖掘机等工程机械需要对施工现场的视觉盲区进行视频监控,确保作业安全.为了满足安全需求,研制了基于i.MX35的挖掘机视频监控系统,使用i.MX35作为视频主处理器、ADV7180作为NTSC/PAL摄像头输出视频的解码芯片、eMMC或PATA接口固态硬盘作为视频存储介质,实现对挖掘机等工程机械作业现场的视频监控、记录与回放等功能,能够显著提高生产效率、保证作业安全,可以广泛应用于挖掘机等工程机械的控制系统中.

英文摘要：

Excavators and other construction machineries need field video monitoring to eliminate blind spots and ensure safe opera- tion while they are working. To meet the security needs of excavators, the design of a video surveillance system based on i. MX35 is introduced, which uses i. MX35 as the main processor, ADV7180 as the decoder for video output of NTSC/PAL cameras, and eM- MC or SSD with PATA interface as the video storage medium. The designed system has the capabilities of video monitoring, record- ing and playing back. It can be widely used in the control systems of excavators to significantly improve productivity and ensure safety.
