Description

technical field [0001] The invention relates to a water area wireless image transmission system of a high-performance unmanned patrol device on water, belonging to the technical field of digital wireless monitoring. Background technique [0002] The development of digital wireless monitoring technology, from the perspective of application, mainly includes two categories: fixed point transmission and mobile transmission. If fixed-point wireless image transmission is an effective supplement to wired monitoring, then moving image transmission technology can never be replaced by wired monitoring. In some special occasions, for example, battlefield reconnaissance, anti-terrorist military exercises and actual combat, on-site monitoring and emergency command of catastrophic events, and "emergency handling (handling of emergencies)" of law enforcement agencies such as public security or maritime affairs, etc., all require a central commander The direct and real-time observation of ...

Problems solved by technology

[0009] Satellite communication equipment (communication equipment in motion) has three disadvantages: First, when using it, it must be reserved and coordinated with the satellite department in advance. Of course, this problem is gradually being improved by strengthening management; second, the fee is charged according to the use time , maybe this is a factor that affects the promotion; the third insufficient aspect is that the communication signals between the vehicle-mounted satellite equipment and the satellite are transmitted in a straight line (commonly known as line-of-sight transmission, Line Of Sight), because our vehicles on the ground There is an angle of inclination between the satellite and the synchronous satellite, so if you are in a mountainous area or in an environment with dense and relatively high buildings in the city, the signal between the vehicle and the satellite may be blocked by these buildings or mountains and cause interruption

Thirdly, in most areas where major incidents occurred, mobile phone base stations are almost at full capacity, and network data transmission is impossible (for example, at the scene of the Shenzhen torch relay, it is difficult to get through with mobile phones on site, and wireless Internet access is even more impossible). That is to say, the more in an emergency situation, when the equipment needs to work, the more it cannot be put into use

[0018] 1), ultra-low delay characteristics, the usual MEG-2 video encoder, due to the delay caused by compression encoding, generally on the order of 1-2 seconds (25 frames-50 frames), we are in the front-end PTZ lens When controlling, this delay is very inconvenient, making it difficult to aim the camera at the target after holding the whole action for 1 second
