Design of CMOS Sensor Image Monitoring System Based on Ethernet Technology

采用网络控制芯片DM9008作为通信接口开发了一种基于以太网的图像监测系统。用专用图像处理芯片、利用高速单片机及FPGA技术、CMOS图像传感器技术进行实时图像信号的采集和处理,图像经过处理后通过以太网传输至PC机端接收、解压、管理和显示。实验表明:这种系统的设计灵活性好、柔性强,以太网控制器实现图像的数据传输使系统数据传输速度和稳定性大大提高,软件设计时的模块化结构使系统的通用性和可移植性增强,也有利于功能扩展。

Combined the technologies of electron, computer, embedded system, communication and digital signal processing, a kind of intelligent, digital and miniaturization image-monitoring system was developed. The pairs of images obtained from CMOS image sensors were transmitted to the PC through the Etheruet after processing by DSP. It has been proved that this system can shorten development cycle and ensure the design of the system nice flexibility. With the help of the Ethernet controller, the system has characteristics of high data transport rate, nice real-time control, high stability. The modularization structure of software has good flexibility, and is in favor of the extension of system function.
