Description

Technical Field

[0001] This utility model relates to the field of drone protection technology, and in particular to an anti-interference structure for drone sensor signal acquisition. Background Technology

[0002] During drone operations, the sensors they carry need to accurately collect various environmental signals and equipment status signals. These signals are crucial for the drone to achieve autonomous navigation, mission execution, and data feedback. However, drones typically operate in complex and changing environments, making them susceptible to various external interferences, such as electromagnetic interference, radio frequency interference, and environmental noise interference. These interferences can cause distortion, increased errors, or even loss of signals collected by sensors, severely affecting the drone's accuracy and stability, and potentially even leading to flight safety accidents. Therefore, implementing anti-interference measures during the drone's sensor signal acquisition process is of paramount importance.

[0003] In existing technologies, when performing anti-interference operations for UAV sensor signal acquisition, simple shells are typically used to block external electromagnetic interference through basic shielding. However, this is insufficient to effectively address the combined effects of multiple interference sources in complex environments. When the UAV is in an area with strong electromagnetic radiation or an environment where multiple frequency interference signals are superimposed, the shielding effect of this single anti-interference structure decreases significantly, failing to effectively isolate the influence of interference signals on sensor signal acquisition. Dual or multiple anti-interference capabilities are relatively insufficient, making it difficult to meet the requirements of high-precision UAV operations. Furthermore, the anti-collision and drop protection capabilities are relatively inadequate, offering only average protection. Therefore, we propose an anti-interference structure for UAV sensor signal acquisition to address the aforementioned problems. Utility Model Content
