The invention performs orthogonal frequency division multiplexing modulation on the optical signal, and realizes the communication between the mobile command station terminal and the mobile robot terminal.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a mobile robot wireless optical communication system of orthogonal frequency division multiplexing. Background technique [0002] The mobile EOD robot is a special equipment used by EOD personnel to dispose or destroy explosive suspicious objects. It can be used to carry and transfer explosive suspicious objects and other harmful objects. It replaces EOD personnel with tools to destroy explosives to avoid unnecessary explosions. Casualties. [0003] In many countries, in addition to the bombs dropped by terrorists, there are also a lot of ammunition left over from wars. For example, Kuwait after the Gulf War was an ammunition depot that could explode at any time. According to incomplete statistics, 16 countries manufactured as many as 250,000 landmines, 850,000 artillery shells, and 25 million bullets of mines and submunitions dropped during the war in...

AI Technical Summary

Problems solved by technology

[0005] Traditional mobile EOD robots generally use wired or wireless methods for control and data transmission. The wired method is very inconvenient because it requires a long cable, while the wireless method generally uses radio control, but for some specific conditions, such as nearby Strong magnetic field interference or explosives themselves will be detonated by electromagnetic waves. At this time, traditional radio communication EOD robots cannot be used.
