Abstract

The present invention provides a video monitoring front-end system which comprises the following components: a camera shooting module which is used for collecting the field video image; a DSP module which is used for real-time compressing the video image with a high speed; an ARM module which is used for realizing the control to DSP module and FPGA module; and an FPGA module which is used for realizing the data exchange between the DSP module and the ARM module. The video monitoring front-end system of the invention realizes the high-quality and high-reliability real-time video monitoring function and has the advantages of low cost, simple device structure, convenient installation, convenient use and convenient maintenance. The problems of inferior stability and complicated maintenance existing in the video monitoring front-end system based on PC machine card insertion type in prior art are overcome.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video monitoring front-end system. Background technique [0002] The monitoring front-end system composed of cameras and digital optical transceivers realizes the digital transmission of video data and solves the problem of limited transmission distance in analog mode. However, due to the lack of video compression, the communication bandwidth occupied by monitoring video images is huge and does not Conducive to storage and management. [0003] The prior art provides a PC (Personal Computer, personal computer) plug-in card-based video monitoring front-end system, which realizes video compression by means of computing power of the PC. [0004] In the process of realizing the present invention, the inventors found that the PC card-based video surveillance front-end system in the prior art has the problems of poor stability and complicated maintenance. Contents of the invention ...
