Abstract

The invention relates to a carrier high-speed wireless wideband image transmission system, belonging to the multimedia information transmission technique. Wherein, said device comprises a carrier image emitter and a ground fixed image receiver; the carrier image emitter comprises an image camera and a wireless image emitter, which can be carried by aircraft to camera the on-site image and send signal, via the wireless transmission channel, based on superior digit television ground broadcast technique; the ground fixed wireless image receiver is used to receive and recover the signal sent from the carrier image emitter, then display image signal directly or transmit the recovered image signal to needed position by some relay. The invention can be used in special conditions as spaceflight engineering, etc, or the conditions as city emergency mechanism.

Description

technical field [0001] The invention relates to a wireless image transmission system, in particular to an airborne wireless broadband image transmission system suitable for helicopters, and belongs to the technical field of multimedia information transmission. Background technique [0002] The wireless image transmission system has become a very important and necessary device and component in modern search and rescue. Especially in some special occasions, such as spaceship return module landing, forest fire, sea rescue, major accident scene, etc., all require rescue devices (for example, rescue helicopters, rescue vehicles or rescue ships) to be equipped with wireless image transmission systems, In order to be able to transmit the on-site situation to each measurement and control point and command center in real time, and provide necessary technical reports and means for the leadership's decision-making and command. At present, two methods are generally used for image trans...
