Vehicle-mounted satellite uplink system with full-function box-type structure

Abstract

The invention discloses a vehicle-mounted satellite uplink system with a full-function box-type structure, which comprises a satellite transmission technology system and a vehicle body, wherein the satellite transmission technology system comprises an antenna part, a satellite radio frequency system part, a video and audio coding and decoding system part, a power distribution system and peripheral equipment. The satellite transmission technology systems are respectively integrated and installed in a plurality of aviation cases, and the aviation cases are placed and fixed in a carriage of a vehicle body, so that the satellite vehicle can be combined with the vehicle body as a whole to be used as a satellite vehicle, and the aviation cases loaded with satellite systems can be separated from the vehicle body to be independently used in a special environment. The system has the advantages that various vehicle-mounted and box-mounted application scenes can be realized. The satellite transmission technology system and the vehicle body in the system can be integrally combined for use and can also be separated from the vehicle body for independent use, so that the satellite transmission technology system and the vehicle body can be creatively combined for use, are independent from each other and do not restrict each other, and use requirements in various environments can be met.

Description

technical field [0001] The invention relates to a vehicle-mounted satellite uplink system with a full-function box-type structure, which belongs to the field of radio and television satellite transmission. Background technique [0002] With the increasing number of live broadcasts of TV stations, it has also undertaken more and more live transmissions of sports events and major conferences. At present, the satellite transmission system of the TV station is severely restricted by the live broadcast venue and the environmental conditions, and has been unable to meet the increasing demand for programs. For example, the original satellite vehicle could not reach mountainous areas and other inconvenient areas for broadcasting; the technical system of the original satellite vehicle was limited by basic equipment such as vehicles and generators, and damage to the vehicle or generator would directly cause the satellite transmission system to fail to function normally; the original b...

AI Technical Summary

Problems solved by technology

At present, the satellite transmission system of the TV station is severely restricted by the live broadcast venue and environmental conditions, and can no longer meet the increasing demand for programs.

For example, the original satellite vehicle could not reach mountainous areas and other inconvenient areas for broadcasting; the technical system of the original satellite vehicle was limited by basic equipment such as vehicles and generators, and damage to the vehicle or generator would directly cause the satellite transmission system to fail to function normally; the original broadcasting And the broadcast uplink system is single. During the broadcast of important conferences and events, the satellite transmission system can easily become a single node without backup, which affects safe transmission; there are few satellite transmission equipment, which is not suitable for marathon broadcasts, which have low single-point security requirements. However, there are many broadcast points, and there is no way to split the whole system into multiple systems.
