Novel signal encryption transmission system based on Raman spectrum and embedded electronic circuit

Abstract

The invention relates to the technical field of signal transmission, in particular to a novel signal encryption transmission system based on a Raman spectrum and an embedded electronic circuit, which comprises a Raman optical transmission system laser signal transmitting device, a laser transmission adjusting module and a Raman spectrum signal optical demodulation device. Line laying is not needed in the transmission process, only the catadioptric lens needs to be adopted to adjust an optical path when part of the optical fiber is shielded by an object, and the line laying and maintenance cost in current optical fiber transmission is completely saved. Meanwhile, in order to ensure the confidentiality of the information in the transmission process, random number generation in a certain range combined with a single chip microcomputer is adopted to form first encryption; when the laser enters a special decryption software system, the random number can be obtained, and second encryption is formed; the random number corresponds to the serial number of the sample test tube in a certain range, and third encryption is formed; and the three encryption processes are linked with one another and interact with one another, so that the security of information spreading is greatly improved.

Description

technical field [0001] The invention relates to the technical field of signal transmission, in particular to a novel 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 propagat...

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.
