Problems solved by technology

However, in wireless optical communication technology, if one end of the communication is a moving object (such as a high-speed rail train), the current wireless optical transmission system cannot meet the requirements, and a fast automatic tracking system needs to be added to meet the requirements

Abstract

The invention discloses an optical communication automatic tracking system and an optical communication automatic tracking method. The optical communication automatic tracking system comprises a first automatic tracking control system and a second automatic tracking control system which are communicated with each other; the first automatic tracking control system and the second automatic tracking control system respectively comprises a reflecting mirror assembly, a coarse tracking unit for receiving reflected light rays of the reflecting mirror assembly, an accurate tracking unit for receiving emitted light of the reflecting mirror assembly, a field-programmable gate array electrically connected with the coarse tracking unit and the accurate tracking unit, and a performing mechanism driving unit for driving the reflecting mirror assembly. The performing mechanism driving unit is electrically connected with the field-programmable gate array. As a way of combining the coarse tracking with the accurate tracking is adopted, communication also can be finished well even one end of the communication is a moving object.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an optical communication automatic tracking system and an optical communication automatic tracking method. Background technique [0002] Optical fiber communication technology is a communication method that uses optical fibers to transmit broadband signals to achieve information transmission. Optical fiber communication has the advantages of anti-electromagnetic interference, strong anti-radiation, good confidentiality, wide frequency range, good anti-interference, anti-eavesdropping, and low price. In the absence of optical fiber, only wireless optical communication technology can transmit high-bandwidth signals. As a new type of communication technology, optical wireless communication has the advantages of both optical fiber communication and mobile communication. It can realize broadband transmission, flexible networking, no frequency application, anti-electromag...
