The application discloses a multi-source heterogeneous fusion-based AIoT global perception sensor module of a UAV, which comprises a perception layer composed of image, ranging and environmental physical quantity sensors; a data fusion processing unit based on an FPGA+ARM heterogeneous architecture, which is used for time-space synchronization, feature-level fusion and semantic analysis of multi-source data; a communication and interface unit; an isolated power management unit and a protective shell.The module completes pixel-level registration, RGB-D generation and lightweight AI inference at an edge end, outputs a global semantic map containing an obstacle category, depth information and environmental parameters, and transmits the global semantic map to a flight control and a ground station in real time through a CAN bus and wireless data transmission.The design realizes millisecond-level close coupling fusion of multi-source data, solves the problems of poor real-time performance, asynchronous conflict and bandwidth bottleneck in a traditional scheme, and significantly improves all-weather autonomous perception and obstacle avoidance capability of the UAV.

This utility model discloses a filter integrating differential-mode and common-mode inductors, comprising a housing, an inductor assembly, and a tap assembly. A shielding plate is disposed within the housing. The inductor assembly includes a differential-mode inductor and a common-mode inductor, respectively disposed in the left and right cavities. The tap assembly includes two taps, each consisting of a main portion and two branches. The two branches pass through the top wall of the housing and enter the left and right cavities, respectively. Two independent coils are mounted on the core of the common-mode inductor. A bi-wire wound coil is mounted on the core of the differential-mode inductor. One end of each independent coil is connected to one branch of a tap, and the other end passes through the housing. Each independent coil corresponds to one tap. One end of a wire in the bi-wire wound coil is connected to the other branch of a tap, and the other end passes through the housing. Each wire in the bi-wire wound coil corresponds to one tap. This structure reduces space occupation, lowers production costs, and provides efficient energy transmission and filtering effects.
