A rotor 2 is mounted on the surface of the fuselage 1, landing gear 3 is mounted on the side of the fuselage 1, and a battery pack 4 is mounted on the bottom of the fuselage 1. A connecting ring 5 is fixedly mounted on the surface of the landing gear 3. The fuselage 1, rotor 2, and landing gear 3 are also included. The frame 3 and connecting ring 5 are demagnetized by current shielding and motor power. The fuselage 1, rotor 2, landing gear 3, and connecting ring 5 are all made of lightweight, high-strength materials such as carbon fiber, aviation aluminum alloy, and lithium polymer, which improves overall performance and reduces overall weight.

The bottom surface of the fuselage 1 is fixedly installed with a magnetic detection mechanism 7.

[0028] The magnetic detection mechanism 7 includes a signal processor 701 and a signal processor 702 fixed to the bottom surface of the fuselage 1, a data fusion unit 703, a cesium optical pump probe 704 set at both ends of the fixed rod 6, and a magnetic compensation probe 705 fixed to the surface of the fixed rod 6. It has high sensitivity, high gradient tolerance, and high precision detection, which effectively improves the detection results. The cesium optical pump probe 704 and the magnetic compensation probe 705 are fixed to the surface of the fixed rod 6 by ropes 10. The signal processor 701 and the signal processor 702 are both connected to the data fusion unit 703 and the cesium optical pump probe 704.

It has internal circuits for heating each optical part and circuits for converting electrical signals into frequency signals. The multi-serial port data fusion device merges and processes the data from multiple photoelectric conversion and acquisition devices and sends it out through network port or serial port.
