Light transmission data synthesizer based on LED visible light

Abstract

The invention provides a light transmission data synthesizer based on an LED visible light, a high-speed, reliable and cable-free comprehensive transmission system of multichannel heterogeneous type data can be realized by employing the LED visible light, and the light transmission data synthesizer is mainly used for scenes having a special requirement of an electromagnetic environment including spacecrafts etc. For the special application scene including the spacecraft, wired cable transmission has a series of problems of complex wiring, heavy cables, inflexible communication, and even reliable risks, the realization of cable-free comprehensive transmission of multichannel heterogeneous communication interface data employing the LED visible light is firstly proposed, the light transmission data synthesizer is designed, and strong application advantage is achieved in inter-stage separation surfaces of the spacecrafts and in other fields which are not suitable for wired cable communication.

Description

technical field [0001] The invention relates to an optical transmission data synthesizer. Background technique [0002] At present, in the design of the communication system of the launch vehicle, copper core cables are generally used as the transmission path of electrical signals between devices. There are problems such as heavy cables, expensive cables, and difficult wiring. Communication applications on the separation surface may also bring reliability risks, such as aerospace When the carrier is separated between stages, the impact of the wired cable connector may cause abnormal unlocking, and the cable-pull separation process of thermal separation may easily cause problems such as sub-insertion damage and back-locking, which may lead to unreliable unlocking of the sub-insertion, partial damage to the socket structure, and internal Short circuit and redundant objects may cause the failure of the split-plug separation, and the high dynamic swing of the cable separation pl...
