Description

Technical Field

[0001] This utility model relates to the field of data transmission, specifically a circular wireless optical communication detachable module. Background Technology

[0002] In recent years, with the continuous development and application of data transmission technology, in fields such as commercial aerospace and national defense, some inter-cabins with separation and detachment requirements are prone to problems such as large separation forces or even difficulty in separation due to the combined effects of assembly deviations and insertion / removal lifespan. Currently, this problem is mainly solved by wireless optical communication. A high-temperature resistant and high-vibration-resistant inter-cabin wireless optical communication component disclosed in patent document CN117978280 A has the disadvantages of only being able to perform optical communication and not transmit electrical energy, having a short wireless optical communication transmission distance, and having the photodetector easily interfered with by other stray light after separation at both ends. Summary of the Invention

[0003] To address the shortcomings of existing products that can only perform optical communication and cannot transmit electrical energy, and whose photodetectors are easily interfered with by other stray light after separation, this utility model provides a circular wireless optical communication separation and detachment module.

[0004] The technical solution adopted in this utility model is as follows: energy is transmitted by radio electromagnetic coupling; at the same time, the collimator collimates the emitted beam to increase the effective transmission distance of the beam in space; the radio electromagnetic coupling provides power to the separation end module; when the separation end module successfully separates, it cannot receive the power provided by the main body and therefore stops working irreversibly. The photodetector at the separation end cannot receive the light signal and will not be interfered with by other stray light.

[0005] The circular wireless optical communication separation and detachment module is characterized by including a main body module and a separation end module. After information acquisition and processing, the main body module and the separation end module can communicate with each other via wireless spatial light. The main body module provides power to the separation end module through wireless electromagnetic coupling. When the distance between the main body module and the separation end module exceeds the effective range, the separation end module will irreversibly stop working.

[0006] Furthermore, its characteristic is that: the circular wireless optical communication detachable module includes a main body module, a detachable module, a first optical transmitting module, a first optical receiving module, a second optical transmitting module, a second optical receiving module, a first PCB board, a second PCB board, an optical collimation module, a wireless transmitting coil module, a wireless receiving coil module, a first housing, a first cover, a second housing, a second cover, a main body control processing module, and a detachable control processing module. The main body module and the detachable module communicate with each other via wireless spatial light. The main body module provides power to the detachable module via wireless electromagnetic coupling. When the distance between the main body module and the detachable module exceeds the effective range, the entire detachable module irreversibly stops working due to power failure.

[0007] Furthermore, its features are as follows: the main body module includes a first optical transmitting module, a first optical receiving module, a PCB board, an optical collimation module, an FC fiber optic connector, a wireless transmitting coil module, a first housing, a first cover, and a main body control and processing module; one end of the optical transmitting module is connected to the first PCB board, and the other end is an FC fiber optic connector; the first optical transmitting module, the FC fiber optic connector, and the optical collimation module are assembled together, and the beam emitted from the end face of the FC fiber optic connector is collimated and expanded by the optical collimation module; one end of the first optical receiving module is connected to the first PCB board, and the other end is a photodetector, which can receive the beam after collimation and expansion by the separation end module; the wireless transmitting coil module emits magnetic energy to the separation end module through radio electromagnetic coupling within a certain range; the main body control and processing module is installed on the first PCB board and can realize the function of controlling and processing information from the first optical transmitting module, the first optical receiving module, and the wireless transmitting coil module.

[0009] Furthermore, its characteristic is that the main body module controls the first optical transmitting module, the first optical receiving module, and the wireless transmitting coil module through the main body control and processing module, and is uniformly powered by the main body power supply system.

[0010] Furthermore, its characteristic is that after the light from the main body module and the separation module is collimated and expanded by the optical collimation module, the wireless optical transmission distance can reach more than 0.5 meters.

[0011] Furthermore, its features are: the split-end module controls the second optical transmitting module and the second optical receiving module through the split-end control and processing module; the split-end control and processing module, the second optical transmitting module, and the second optical receiving module are independently powered by the wireless receiving coil module power supply system.
