基于WIFI的配电网视频安全监测评估系统实现

Implementation of video security monitoring and evaluation system for distribution network based on WIFI

针对配电网生产环境的监测评估效率需求日益提高的问题,文中基于WIFI无线通信协议设计了一种配电网用实时视频监控系统。该系统设计包含了硬件与软件两部分,硬件部分采用基于ARM9架构的S3C2440 CPU,搭载了WIFI无线网卡和UVC摄像头;而软件系统作为硬件系统的支撑,基于Linux操作系统剪裁实现,实现了系统硬件设备的驱动程序。测试结果表明,当远端视频采集设备在50 m距离下,可以实现140 Mbps的视频流传输速率,显著提升了配网安全检测评估工作的时效性。

In view of the increasing demand for monitoring and evaluation efficiency of distribution network production environment,a real-time video monitoring system for distribution network is designed based on WIFI wireless communication protocol.The design of the system includes two parts:the hardware part adopts the S3C2440 CPU based on ARM9 architecture,which is equipped with WIFI wireless network card and UVC camera;the software system,as the support of the hardware system,is tailored based on the Linux operating system,and the driver of the hardware device is realized.The test results show that the transmission rate of 140 Mbps video stream can be achieved when the remote video acquisition equipment is 50 m away,which significantly improves the timeliness of the distribution network security detection and evaluation.
