摘 要: 基于STM32F407芯片、LAN8720A模块以及OV2640摄像头模块,设计了一种以太网网络视频监控系统。该视频监控系统使用UCOS-Ⅱ系统,以及Lw IP协议栈,利用OV2640摄像头模块采集数据。在UCOS-Ⅱ系统的调度下,使用Lw IP协议栈,利用TCP/IP协议,将采集到的数据上传到PC客户端,PC端能够实时地监控。相比Zig Bee传输技术而言,利用网络传输可大幅度提高数据传输的带宽,可以实现监控视频的实时传输以及高清画面的传输。 This paper designs an Ethernet network video monitoring system based on STM32F407 chip,LAN8720A module andOV2640 camera module. The system uses UCOS-II system and LwlP protocol stack. The OV2640 camera module is used to collect thevideo data. Under the scheduling of the UCOS-II system,the collected data is uploaded to the PC client by using LwlP protocol stackand TCP / IP protocol. The PC can monitor in real time. Compared with the ZigBee transmission technology,the network transmissionmethod can greatly improve the bandwidth of data transmissions, and achieve real-time transmission of monitoring video and high-defini-tion pictures.
