Problems solved by technology

[0004] The single board of the traditional free optical communication system only provides the electrical-optical conversion function with a single function. If multiple different optical-electrical conversion functions are to be realized, a combination of different single boards is required.
If it is used in the field of rail transit, a large space is required to install these different boards, resulting in a great waste of installation space and hardware resources

Abstract

A free space optical communication system, which includes: a physical interface transceiver, the first serial interface of which is used to connect to the grid port, and the second serial interface is used to connect to the optical transceiver; a controller, which transmits and receives the physical interface The transceiver connection is used to generate corresponding transceiver configuration data and transmit it to the physical interface transceiver, so as to realize the configuration of the data channel between the first serial interface and the second serial interface of the physical interface transceiver. This system can realize the flexible configuration of the port by software, so as to realize the data interaction between the optical communication of different wavelengths and the communication of the grid port, which is more flexible than the existing communication system. At the same time, the system can realize multi-channel optical-to-electrical conversion, which can effectively reduce the use of single boards, thereby greatly saving installation space and hardware costs.

Description

technical field [0001] The invention relates to the technical field of vehicle communication, in particular to a free space optical communication system. Background technique [0002] Free Space Optics (FSO) technology uses light with a higher carrier frequency as an information carrier to replace radio frequency / microwave links. It is a very promising wireless communication technology. The high bandwidth of the spectrum has the advantages of high data rate, free and unrestricted spectrum over 300GHz, high security, and easy deployment. Therefore, free space optical communication technology can be used as an effective solution for vehicle-to-ground large-bandwidth wireless communication. [0003] The internal network communication on the train uses 100M or Gigabit Ethernet electrical ports. If the communication data of the train network is to be transmitted in the form of free optical communication, then a special single board is required to realize the electrical-optical si...
