Fingerprint extraction, collection and identification terminal used for police

Abstract

The invention discloses a fingerprint extraction, collection and identification terminal used for the police. The fingerprint extraction, collection and identification terminal used for the police comprises a walking bottom disk, wherein the upper end of the walking bottom disk is rotatably provided with an electric rotary shaft; the upper end of the electric rotary shaft is fixedly provided witha first mechanical arm shaft; the first mechanical arm shaft is rotatably provided with a first mechanical arm; and a mechanical arm cavity is arranged in the first mechanical arm. The fingerprint extraction, collection and identification terminal used for the police has a simple structure, is convenient to operate and can automatically carry out no-dead-angle fingerprint search on a crime scene,in addition, a fingerprint can be subjected to extraction processing after a fingerprint trace is found, the fingerprint can be more clearly manifested, meanwhile, after the fingerprint is manifested,the fingerprint is photographed, stored and identified, a policeman can be effectively assisted in investigating the scene, and a fingerprint damage situation caused since excessive investigators areat the scene can be effectively avoided. The fingerprint extraction, collection and identification terminal used for the police has high working efficiency and a high integration degree.

Description

technical field [0001] The invention relates to the related field of information readers, in particular to a police fingerprint extraction and identification terminal. Background technique [0002] As we all know, for the police to handle the case, the fingerprints left on the scene are very important. It can directly help the police find the suspect and help the police quickly detect the key. However, for some crime scenes, the area is very large. The investigation is very complicated, and there is a great possibility that during the investigation period, due to the negligence caused by too many investigators, the fingerprints will be damaged, and the case will not be solved normally. [0003] Therefore, it is necessary to design a police fingerprint extraction collection identification terminal to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a police fingerprint extraction collection identification termi...
