基于电力载波与云计算的视频监控系统设计

针对目前视频监控系统不断升级改造存在的布线工作量大、布线成本高、无法存储及计算海量视频文件的问题,该文提出基于电力载波技术和云计算框架的视频监控系统。视频数据经过调制解调、振荡、放大、耦合等过程,利用电力线网络传输到各分控点,通过互联网传送到云端,利用云端强大的存储、计算能对视频数据进行各种处理。设计中硬件部分的ARM11微处理器主要负责视频数据的采集、编码并封包传送到PLC调制解调模块,完成数据收发控制和系统任务调度。软件部分主要包括开发系统搭建、USB摄像头驱动、视频数据采集、LCD实时显示、网络传输和双核数据处理等。该文的设计充分结合电力载波和云计算的特点,在视频监控领域中具有较高的应用价值。

Aiming at the problems of heavy wiring workload,high wiring cost,and inability to store and calculate massive video files due to the continuous upgrading and transformation of video surveillance systems,this paper proposes a video surveillance system based on power carrier technology and cloud computing framework.Video data goes through processes such as modulation,demodulation,oscillation,amplification,and coupling,and is transmitted to each branch control point using the power line network and transmitted to the cloud through the Internet.The powerful storage and computing capabilities of the cloud are used to perform various processing of video data.The ARM11 microprocessor in the hardware part of the design is mainly responsible for collecting,encoding and transmitting video data in packets to the PLC modulation and demodulation module to complete data transceiver control and system task scheduling.The software part mainly includes development system construction,USB camera driving,video data collection,LCD real-time display,network transmission,dual-core data processing,etc.The design in this paper fully combines the characteristics of power carrier and cloud computing,and has high application value in the field of video surveillance.
