Research on Remote Video Monitoring System Used for Numerical Control Machine Tools Based on Embedded Technology

本文设计了DSP+ARM的独立双核结构的嵌入式视频监控系统.该系统是数控机床的无人化操作的一个重要组成部分,首先对摄像头输入的模拟信号进行数字化处理,然后送到DSP系统,按新一代图像压缩标准H.264进行压缩编码,再将处理好的图像编码以xBus总线传送给ARM系统,ARM系统将DSP传来的压缩编码通过网络协议栈打包,按需求通过网关发给客户端.该系统将WEB技术,嵌入式技术和图象压缩编码等技术有机结合,可广泛应用于数控加工的无人化管理以及智能机器人控制等领域.

This paper designed an embedded video monitoring system using DSP and ARM. This system is an important part of self-service operation of numerical control machine tools. At first the analog input signals from the CCD camera are transformed into digital signals, and then output to the DSP system, where the video sequence is encoded according to the new generation image compressing standard called H. 264. The code will be transmitted to the ARM system through xBus, and then be packed in the ARM system and transmitted to the client port through the gateway. Web technology, embedded technology and image compressing as well as coding technology are integrated in the system, which can be widely used in selfservice operation of numerical control machine tools and intelligent robot control areas.
