The orthogonal frequency division multiplexing wireless optical communication system for the mobile robot in the invention comprises a mobile command station side and a mobile robot side, wherein the mobile command station side is composed of an industrial personal computer, an optical transceiver, an optical signal transmitter, an open-hole reflector, a two-dimensional deflecting mirror, a second micro-processor, a third micro-processor, a first light splitter, a second light splitter, a third light splitter, a first light filter, a second light filter, a third light filter, a first detector, a second detector, a third detector, a first amplification circuit, a second amplification circuit, a third amplification circuit, a first focusing lens, a second focusing lens, a third focusing lens, a fourth focusing lens, a tracking and pointing camera and a display; and the mobile robot side is composed of an optical antenna, a front limiting amplifier, a control acquisition interface and a first micro-processor. According to the orthogonal frequency division multiplexing wireless optical communication system for the mobile robot provided by the invention, optical signals are subjected to orthogonal frequency division multiplexing modulation; and thus, communication between the mobile command station side and the mobile robot side is realized.

Description

technical field [0001] The invention belongs to the technical field of optical communication, in particular to an orthogonal frequency division multiplexing mobile robot wireless optical communication system. Background technique [0002] Mobile EOD robots are special equipment used by EOD personnel to dispose of or destroy explosive suspicious objects. They can be used to transport and transfer explosive suspicious objects and other harmful objects, and use tools to destroy explosives instead of EOD personnel to avoid unnecessary explosions. casualties. [0003] In many countries, in addition to the bombs dropped by terrorists, there are also many ammunition left over from wars. For example, Kuwait after the Gulf War is an ammunition depot that can explode at any time. According to incomplete statistics, in the area of ​​more than 10,000 square kilometers on the Iraq-Korea border, there are as many as 250,000 landmines, 850,000 shells made by 16 countries, and 25 million ...

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.
