[0002] Inductive setting refers to the technology that wirelessly transmits various information affecting the trajectory to the electronic fuze during firing, ensuring that the projectile hits the target.

DETAILED DESCRIPTION

[0031] The present invention will be further described below with reference to the accompanying drawings and examples.

[0032] Example:

[0034] The receiving end includes a first receiving coil 3 and a second receiving coil 4, and the second receiving coil 4 includes a first receiving module 41 and a second receiving module 42 connected to each other and wound in opposite directions;

[0035] The first transmitting module 21 and the second transmitting module 22 are symmetrically arranged with respect to the first transmitting coil 1 and the first receiving coil 3 , and the first receiving module 41 and the second receiving module 42 are symmetrically arranged with respect to the first transmitting coil 1 and the first receiving coil 3 .

[0036] like Figure 1 、 Figure 2 and Figure 3 As shown, the first transmitting module 21 and the second transmitting module 22 have the same number of winding turns, and the first receiving module 41 and the second receiving module 42 have the same number of winding turns.

[0037] In this embodiment, if Figure 1 As shown, the first transmitting coil 1 and the first receiving coil 3 are both symmetrical about the XY plane, and the first transmitting module 21 and the second transmitting module 22, as well as the first receiving module 41 and the second receiving module 42, are symmetrically arranged about the XY plane. The first transmitting coil 1, the first receiving coil 3, the first transmitting module 21, the second transmitting module 22, the first receiving module 41 and the second receiving module 42 all have a symmetrical coil structure about the YZ plane.

[0038] In this embodiment, the magnetic fields generated by the first transmitting module 21 and the second transmitting module 22 on the first receiving coil 3 are equal in magnitude and opposite in direction, which cancel each other out to achieve coil decoupling, effectively decoupling the first receiving coil 3 from the second transmitting coil 2. The magnetic fields generated by the first receiving module 41 and the second receiving module 42 on the first transmitting coil 1 are equal in magnitude and opposite in direction, which cancel each other out to achieve coil decoupling, effectively decoupling the first transmitting coil 1 from the second receiving coil 4. During the induction setting process, the two coupling mechanisms formed by the first transmitting coil 1 and the first receiving coil 3, and the second transmitting coil 2 and the second receiving coil 4, respectively, serve as the energy and signal transmission systems, eliminating the problem of interference between the energy and information transmission channels.

[0039] As an embodiment of the transmitting end of the present application, Figure 2 As shown, the first transmitting coil 1, the first transmitting module 21 and the second transmitting module 22 are all three-dimensional fan-ring spiral coils;

[0040] The first transmitting module 21 and the second transmitting module 22 are symmetrically arranged at the upper and lower ends of the first transmitting coil 1 . The first transmitting coil 1 , the first transmitting module 21 and the second transmitting module 22 are all wound on the transmitting magnetic core 5 .

[0041] In this embodiment, the first transmitting coil 1 is wound in the same layer as the first transmitting module 21 and the second transmitting module 22. The transmitting magnetic core 5 is a sector-shaped magnetic core. The first transmitting module 21 is wound clockwise, while the second transmitting module 22 is wound counterclockwise. The first transmitting module 21 and the second transmitting module 22 are wound from a single Litz wire. Winding begins at the top of the first transmitting module 21, first winding the first transmitting module 21 clockwise, and then winding the second transmitting module 22 counterclockwise.

[0042] As another embodiment of the transmitting end of the present application, Figure 3 As shown, the first transmitting coil 1 and the second transmitting coil 2 are both arcuate spiral coils, the first transmitting module 21 and the second transmitting module 22 are respectively the two winding edges of the arcuate spiral coils, the arcuate surfaces where the first transmitting coil 1 and the second transmitting coil 2 are located are coaxially arranged, and the second transmitting coil 2 and the first transmitting coil 1 are arranged in layers.

[0043] In this embodiment, as shown in Figure 3, the first transmitting coil 1 is a curved DD-type coil, and the second transmitting coil 2 is a curved rectangular coil. The second transmitting coil 2 is wound with a single Litz wire. The currents in the first transmitting modules 21 and the second transmitting modules 22 at the upper and lower ends of the second transmitting coil 2 flow in opposite directions. Therefore, the magnetic fields generated by the second transmitting coil 2 in the first receiving coil 3 are of the same magnitude but in opposite directions. The second transmitting coil 2 is decoupled from the first receiving coil 3.

[0044] As an embodiment of the receiving end of this application, Figure 4 As shown, the first receiving coil 3, the first receiving module 41 and the second receiving module 42 are all three-dimensional circular spiral coils;

[0045] The first receiving module 41 and the second receiving module 42 are symmetrically arranged at the upper and lower ends of the second receiving coil 4 . The first receiving coil 3 , the first receiving module 41 and the second receiving module 42 are all wound on the receiving magnetic core 6 .

[0046] In this embodiment, the first receiving coil 3 is wound on the same layer as the first and second receiving modules 41, 42. The receiving magnetic core 6 is a sleeve-shaped magnetic core. In this embodiment, the first receiving module 41 is wound clockwise, while the second receiving module 42 is wound counterclockwise. The first and second receiving modules 41, 42 are wound from a single Litz wire. Winding begins at the top of the first receiving module 41, first winding the first receiving module 41 clockwise, then winding the second receiving module 42 counterclockwise.

[0047] As another embodiment of the receiving end of this application, Figure 5As shown, the first receiving coil 3 is a toroidal spiral coil, the first receiving module 41 and the second receiving module 42 are both three-dimensional circular spiral coils, the first receiving module 41 and the second receiving module 42 are coaxially arranged with the toroid where the first receiving coil 3 is located, and the first receiving module 41 and the second receiving module 42 are arranged on the inner side or the outer side of the first receiving coil 3.

[0048] In this embodiment, if Figure 5 As shown, the first receiving coil 3 is a toroidal DD type coil, and the first receiving module 41 and the second receiving module 42 are wound by a Litz wire. When winding, the winding starts from the upper end of the first receiving module 41, first winding the first receiving module 41 clockwise, and then winding the second receiving module 42 counterclockwise.

[0049] In this application, any combination of the above-mentioned transmitter embodiment and receiver embodiment can achieve decoupling of the energy transmission channel from the signal transmission channel. In summary, this application achieves a coupling mechanism that only couples the two pairs of main coils, while decoupling the other coils, through the symmetrical design of the coil structure and the control of the magnetic field direction. This solves the problem of mutual interference between the energy and information transmission channels of the induction setting system and has practical application value.
