Signal encryption transmission system based on Raman spectroscopy and embedded electronic circuit

Abstract

The invention relates to the technical field of signal transmission, in particular to a signal encryption transmission system based on Raman spectroscopy and embedded electronic circuits, comprising a Raman optical transmission system laser signal transmitting device, a laser transmission adjustment module and a Raman spectral signal optical demodulation device, The present invention is base station transmission, and no line laying is required in the middle of the transmission, except that the catadioptric lens can be used to adjust the optical path when some objects are blocked, which completely eliminates the cost of line laying and maintenance in the current optical fiber transmission; In order to ensure the confidentiality of information in the process of dissemination, random number generation within a certain range combined with single-chip microcomputer is used to form the first encryption; when the laser enters a special decryption software system, the random number can be obtained, forming the second encryption. ; The random number within a certain range corresponds to the sample test tube number, forming the third encryption; the three encryptions are interlocked and interact, which greatly increases the security of information dissemination.

Description

technical field [0001] The invention relates to the technical field of signal transmission, in particular to a signal encryption transmission system based on Raman spectroscopy and embedded electronic circuits. Background technique [0002] Signal transmission systems have always been a focal area of ​​research in electronics technology, and have been gaining momentum in recent years. The responsibility of the signal transmission system is to realize remote transmission of information such as voice, data and images. The signal transmission system mainly includes three parts: carrier modulation area, propagation area and signal demodulation area. In the carrier modulation area, the information to be transmitted is converted into an electrical signal, and after modulation, the electrical signal containing the information is attached to a specific transmission medium, such as laser, etc., which are beneficial to the transmission of electromagnetic waves. In the propagation ar...

Problems solved by technology

However, due to the physical nature of optical fibers, a large number of people are often required to make optical fibers and bury them.

Moreover, with the development of society, the increase of communication channels requires constant adjustments to the lines, resulting in poorer concealment of optical fibers. There are many defects in optical fiber transmission systems that need to be improved.
