Description

Technical field: [0001] The invention relates to a two-way motion full-duplex wireless optical communication system, which is used for high-speed data transmission between moving equipment on a straight and horizontal track, and belongs to the field of optical fiber communication. Background technique: [0002] Wireless optical communication is also called free space optical communication (Free Space Optics, FSO for short), also known as infinite laser communication. Compared with microwave communication, wireless optical communication uses the atmosphere as the transmission medium, avoiding expensive fiber laying and maintenance work; no need to apply for a frequency license; high data transmission rate, large information capacity; good electromagnetic compatibility, strong anti-electromagnetic interference ability ; Low cost, simple construction. It is precisely because of these advantages that it has become a new broadband wireless access technology and has attracted wid...

AI Technical Summary

Problems solved by technology

[0003] Although FSO has many advantages, there are also some problems that cannot be ignored: 1. FSO is a line-of-sight broadband communication technology. When the transmission exceeds a certain distance, the beam will become wider, making it difficult for the receiving point to receive it correctly, causing communication signal distortion. Interruption; 2. Weather effects, rain, snow, fog have a greater impact on the transmission quality; 3. Object blocking and shaking will affect the alignment between the transmitting end and the receiving end; 4. Lasers exceeding a certain power may be harmful to people Eyes are affected, so the laser power must meet eye safety standards

However, when one end shakes or moves relative to each other, the data transmission will be greatly affected, and complex tracking and control devices are required to align the laser beams at both ends, which increases the complexity of the equipment and makes it difficult to carry out maintain

In some occasions of field application (such as the monitoring of loading and unloading status of large-scale port containers), the wireless optical communication equipment often moves in a straight line with the mechanical equipment. At this time, the wireless optical communication system with both ends fixed and stationary cannot meet the requirements
