Abstract

The invention provides an internal communication link system and an unmanned aerial vehicle, and the system comprises an Ethernet communication link; a sensor assembly which comprises a sensing module, a data receiving and transmitting module and a sensor control module, wherein the sensing module and the data receiving and transmitting module are communicated through the Ethernet communication link. According to the technical scheme of the invention, the data transmission rate can be greatly improved, and the method can also be used for the upgrading and data transmission of the sensing module, thereby improving the convenience for a user to take the sensing data.

Description

technical field [0001] The embodiment of the present invention relates to the field of data transmission, in particular to a sensor communication link system. Background technique [0002] UAVs have become commonly used aircraft in people's life and production, for example, UAVs used for shooting, exploration, detection, and plant protection. Today's drones are usually equipped with many sensor components, such as cameras, barometers, GNSS modules, radars, and lidars. These sensor components typically generate large amounts of data, so the data transfer requirements within the sensor are high. For example, in radar, the signal collected by the radar will be transmitted to the flight control module of the drone for processing. Moreover, in some special cases, such as the need to detect multi-directional information, rotating radar will also be used. However, in the rotating radar, the radar radio frequency transmitting part is rigidly connected with the central data proces...
