摘要
基于OV2640摄像头模块设计了一种网络视频监控系统,由视频监控节点、服务器、PC客户端和安卓客户端组成。视频监控节点由STM32F407VE控制器、DP83848以太网模块、OV2640摄像头模块构成,控制器在程序中调用LwIP协议栈的RAW API,实现将TCP网络数据上传至服务器。PC客户端或安卓客户端通过网络登录到服务器后,即可获得实时监控视频。运行测试表明,系统具有视频质量好、占用网络带宽小、成本低、多平台和多终端监控的诸多优点。
A network video surveillance system based on OV2640 camera module is designed, which consists of the video surveillance node, the server, the PC client and the Android client. The video surveillance node contains the STM32F407VE controller, DP83848 Eth- ernet module,OV2640 camera module. The controller uploads TCP network data to the server by calling RAW API of LwIP stack in the program. The PC client or Android client obtains the real-time surveillance video after logging into the server. The operation test indicates that the system has many advantages such as good video quality, low bandwidth, low cost, multi-platform and multi-terminal monitoring.
