Embodiment Construction

[0021] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0022] A double anti-counterfeiting fingerprint acquisition device based on capacitance effect and pulse detection, including a fingerprint acquisition head and a control unit.

[0023] Such as figure 1 As shown, the fingerprint collection head is composed of a sensor for collecting information, a light source for generating and emitting laser light, and a prism 1 for reflecting the laser light emitted by the light source; the sensor includes a fingerprint collection sensor 4 for collecting fingerprint data of punchers 1. The pulse sensor 5 for collecting the pulse data of the puncher and the capacitive human body contact sensor 6 for judging whether the puncher directly punches the card with the skin of the finger; the fingerprint collecti...

Abstract

The invention discloses a double-anti-fake fingerprint collecting device based on capacitance effect and pulse detection, which comprises a fingerprint collecting head and a control unit, and is characterized in that the fingerprint collecting head consists of a sensor for collecting information, a light source for producing and transmitting laser and a prism for reflecting the laser transmitted from the light source, wherein the sensor comprises a fingerprint collecting sensor (4), a pulse sensor (5) and a capacitor-type human body contact sensor (6); the light source comprises a fingerprint collecting light source (2) and a pulse detection light source (3); and the control unit consists of a microcontroller, a fingerprint collecting unit, a pulse detection unit and a contact detection unit. The capacitor-type human body contact detection is combined with the pulse detection, simulation products such as fingerprint sleeves or fingerprint films are not worn by a card puncher can be judged through the combination of the capacitor-type human body contact detection with the pulse detection, and the collection of the fingerprint can be successfully completed; the behavior for punching a time card for others can be effectively prevented, and the management work of enterprises and institutions can be favored; and the behavior for punching the time card for others can be effectively prevented, and the information and property security of users adopting the fingerprint as a password can be guaranteed.

Description

technical field [0001] The invention relates to a double anti-counterfeit fingerprint collection device based on capacitance effect and pulse detection. Background technique [0002] With the rapid development of social science and technology, the research on fingerprint recognition technology has become more and more mature, and the application of fingerprint recognition technology is becoming more and more extensive. Especially in some fields of identity verification, the research and development of fingerprint recognition related products has important strategic significance and a broad market. In the future, the fingerprint time attendance puncher is one of the important products. [0003] At present, the fingerprint collection devices on the market only use simple fingerprint form verification. In order to meet the needs of some punchers in the market to cope with the fingerprint attendance system of enterprises and units, some research institutions have invented a fing...
