Abstract
The invention relates to a vein acquisition apparatus which comprises a sunshade, a limiting plate and an acquisition module, wherein the sunshade is arranged on the limiting plate; a supporting plate is arranged below the limiting plate; supporting columns are arranged between the limiting plate and the supporting plate; the acquisition module is fastened on the supporting plate through a fixing piece; and a protective cover is arranged outside the sunshade. A vein is read on a near infrared site and compared with a vein module of a database for identification, so that the vein acquisition apparatus is high in identification rate, good in actual effect and strong in practicability.
Description
Technical field
The invention belongs to security device manufacturing technology field, be specifically related to a kind of vein acquirer.
Background technology
Entrance guard security system has been widely used in the places such as office, Archives Administration, hospital, exhibition center, museum, also can be used as the places such as factory, military applications, files keeping facility, by fingerprint, recognition of face Based Intelligent Control, fire detecting and alarm, gas leak detection alarm, infrared theft detection alarm, Fingerprint Lock interlock are withdrawn a garrison etc. and to be realized safety protection function, but it is actually rare to utilize the biological identification technology such as palm vein to be applied to the report of security product.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, a kind of vein acquirer has been proposed, described harvester uses the near infrared ray scene to read vein, with the identification of comparing of data base's vein template, discrimination is high, only needs palm is put in the sensor top, can realize identification, actual effect is good, and is practical.
Technical scheme of the present invention is: a kind of vein acquirer; comprise shade, limiting plate and acquisition module; described shade is installed on the limiting plate; below limiting plate, be provided with gripper shoe; between limiting plate and gripper shoe, be provided with support column; described acquisition module is fastened on the gripper shoe by a fixture, in the outside of described shade, is provided with a protective cover.
Described protective cover comprises cover body and base plate, and described cover body is hemispherical dome structure, and its surface is provided with a film plating layer, and described base plate is positioned at the bottom of cover body, and cover body and base plate are solidified into integrative-structure.
Described film plating layer scribbles the thin-film material with optical filtering, can filter out other outer light of infrared ray.
Described shade is column construction.
The described limiting plate structure that is square.
Be provided with display lamp at described limiting plate.
Described shade adopts the ABS material, is provided with in its surface decorative pattern, and its color is black.
The present invention has following beneficial effect:
1) the present invention uses the near infrared ray scene to read vein, and with the identification of comparing of data base's vein template, discrimination is high, and actual effect is good, and is practical.
2) the present invention is simple to operate, only needs palm is put in the sensor top, can realize identification.
3) accuracy of identification of the present invention is high, and people's palm vein is thicker, and quantity is many, can realize high-precision identification.
4) the present invention is safe, and corresponding rate is high, and palm vein is the human body internal information, forges especially difficulty.
5) volume of the present invention is little, and is lightweight, easy to carry.
6) center-control part of the present invention adopts the bus mode expansion with part of data acquisition, and extended mode is flexible.
