用于电缆线路运维管理的视频压缩装置
摘要：
一种用于电缆线路运维管理的视频压缩装置，属于电力系统维护设备领域。本实用新型的目的是通过视频摄像头来获取视频信号，然后将模拟的PAL制式视频信号转换为数字视频信号，再将视频数据传入到DSP中进行传输和存储的用于电缆线路运维管理的视频压缩装置。本实用新型是由视频数据采集模块、信号的缓存与控制模块和压缩控制模块构成，视频数据采集模块接收模拟摄像头输入端T模拟摄像头的信号。本实用新型结构简单，操作使用方便。通过模拟的视频摄像头来获取视频信号，然后采用模数转换芯片SAA7111将模拟的PAL制式视频信号转换为YUV4:2:2的数字视频信号。最后对处理完的视频数据进行传输和存储。同时，主处理器DSP还负责对视频采集芯片进行初始化配置。
摘要（英）：

The utility model provides a video compression device for cable run operation and maintenance management, belongs to the electric power system service equipment field. The utility model discloses an acquire video signal through the video camera, then convert the PAL -system formula video signal of simulation into digital video signal, spread into video data into transmit among the DSP and save a video compression device for cable run operation and maintenance management again. The utility model discloses a buffer memory by video data collection module, signal constitutes with control module and compression control module, and video data collection module receiving mold plans the signal of camera input T simulation camera. The utility model discloses simple structure, operation convenient to use. Video camera through the simulation acquires video signal, then adopts analog -to -digital conversion chip SAA7111 to convert the PAL -system formula video signal of simulation into YUV4: 2: 2 digital video signal. Transmit and save the video data who handles at last. Simultaneously, host processing ware DSP still is responsible for carrying out the initialization configuration to video capture chip.
