Problems solved by technology

However, the limited connection requires the laying of cables, and the wireless connection requires the assumption of a transmitting station. If it is in a remote or harsh environment, the cost of laying cables and building a transmitting station is high, which becomes an obstacle to the application of video surveillance systems

Abstract

The invention discloses a video monitoring system based on satellite communication. The video surveillance system includes an on-site video acquisition unit, a communication satellite, a central station, a network transmission unit and a monitoring terminal which are connected in sequence. According to the invention, by the fusion of satellite communication technology and video monitoring technology, a video monitoring area covers a wide area without geomorphic and geographical restrictions, and a transmission line is stable. Signals will be ended neither in a stationary condition nor in a fast-moving process of a vehicle; and the video monitoring system can keep in contact with the central station through a satellite no matter on a flat highway or at a disaster site of poor road conditions. The video monitoring system based on the satellite communication can go deep into a no man's land, operate in an area with no mobile signal coverage just as in an urban area with strong signals, and be used for transmitting clear on-site video images and voice signals for communication with the central station. The invention can be widely applied to various video monitoring systems.

Description

technical field [0001] The invention relates to the field of security monitoring, in particular to a video monitoring system. Background technique [0002] BUC: Block Up-Converter, the up-conversion power amplifier. Convert the L-band signal output by the satellite Modem into a high-frequency radio frequency signal and send it back to the C-band, KU-band or KA-band satellites. [0003] LNB: Low Noise Block, high-frequency head, that is, low-noise down-converter, its function is to amplify and down-convert the satellite signal transmitted by the feed source, convert the Ku or C-band signal into L-band, and transmit it to satellite receiver. [0004] E1: Telecom standard, using synchronous time division multiplexing technology to combine 30 voice channels (64KB) and 2 control channels (16kb) on a 2.048 high-speed channel. [0005] IP: IP is the abbreviation of Internet Protocol in English (a protocol for interconnection between networks). [0006] As an important part of t...
