Problems solved by technology

[0004] At present, "fingerprint identification" is often only used as an auxiliary means of criminal investigation, but its application is not widespread enough. The main problems are: first, "fingerprint comparison" needs to be processed by large-scale machines, and the price and time cost are relatively high; And the extraction method is relatively complicated, especially most latent fingerprints require chemical treatment to be truly visible; finally, before fingerprint extraction, it is necessary to inspect the hidden places of latent fingerprints in advance to determine the hidden areas of fingerprints, so as to accurately extract and identify fingerprints. It is a tedious and time-consuming process
At the same time, there is no integrated system that can simultaneously complete self-initiating alarm and fingerprint positioning acquisition in the prior art

Abstract

The invention discloses a self-initiating alarm and fingerprint positioning acquisition system, the self-initiating alarm and fingerprint positioning acquisition system includes a nano generator and an alarm system, and the nano generator is used to convert the mechanical energy generated by the touch of foreign matter into Electric energy and output electrical signals, while collecting foreign matter information; the alarm system is used to receive the electrical signal output by the nanometer generator, and alarm to realize self-triggering alarm while being able to collect the fingerprint of the person who triggered the alarm system, and The fingerprint acquisition and identification method is very simple and convenient for actual industrialization.

Description

technical field [0001] The invention belongs to the field of fingerprint location acquisition and alarm, in particular to a self-initiating alarm and fingerprint location acquisition system. Background technique [0002] Fingerprint is recognized as one of the most important individual characteristics in the world. Everyone's fingerprints are different, so fingerprints are often widely used in criminal investigation and secrecy work. Fingerprints can be divided into obvious lines, that is, visible lines; formed stable lines, that is, fingerprints imprinted on soft materials, such as candles and clay by hand contact; latent fingerprints, that are formed by transfer of natural body secretions such as sweat fingerprint texture. Among them, latent fingerprints are not easy to find visually. This type of fingerprint is the most common in crime scenes, and this type of fingerprint cannot be seen by naked eyes. fingerprint. [0003] For latent fingerprints, if they are left on t...
