Abstract

The invention discloses an unmanned aerial vehicle multiplex video switching device. According to the multiplex video switching device, a main control unit is controlled with a thumb wheel switch or an industrial personal computer so as to cause the main control unit to drive a multiplex switching unit, so the input not only can be switched to the output, and but also can be outputted to different output channels according to a certain time sequence, and a power amplification circuit is designed in the circuit for video output signals at the same time, so the distributed capacitance can be effectively reduced, the circuit board area can be reduced and the operation of the whole system is more stable. The multiplex switching unit of the invention adopts a eight-channel video high-speed multiplexing chip produced by the MAX company, the switching time is 40ns, and compared with a multiplex mechanical switch of a passive switching device, the large contact noise problem occurring in the switching process does not exist, and the poor contact problem also does not exist.

Description

technical field

[0001] The invention relates to a UAV multi-channel video switcher, in particular to a UAV multi-channel real-time image switcher, belonging to the technical field of video processing. Background technique

[0002] UAV technology is an important development direction of military equipment technology in the 21st century. In several local wars in the past 10 years, UAVs have played a huge role. Due to the unique advantages of UAVs such as long-distance, all-time, real-time reconnaissance and positioning, it was soon used in aerial photography, aerial reconnaissance and other fields. With the extensive application of UAV aerial photography and aerial reconnaissance technology and in order to better allow ground command and control personnel to understand the UAV's own attitude in real time, more and more UAVs at home and abroad are equipped with surveillance cameras on the fuselage . Due to the limitation of the UAV test telemetry transmission equipment, that ...
