Flash alarm type clock-in machine

Abstract

The invention discloses a flash alarm-type punch card machine for work, which comprises a cabinet body and a main control chip arranged in the cabinet body, a human body electrostatic impedance value detector, a card reader, a power supply circuit unit and a display unit, the display unit and the reading unit. The card device is electrically connected with the main control chip, and the human body electrostatic impedance detection circuit unit transmits the detected human body electrostatic impedance information to the main control chip through the signal amplification circuit unit and the signal acquisition circuit unit in turn, and the main control chip transmits the human body electrostatic impedance information and attendance The information is decoded and sent to the display unit; the cabinet body is provided with a detection interface electrically connected to the electrostatic impedance transmission wrist, and the electrostatic impedance transmission wrist is electrically connected to the human body electrostatic impedance detection circuit unit through the detection interface, and the main control chip is electrically connected to a Flashing sirens. During the inspection, if a problem is found, it can be sent to the police by flashing in time.

Description

technical field [0001] The invention relates to an attendance checking device, in particular to a clock punching machine for going to work. Background technique [0002] The current attendance equipment uses card swiping or fingerprint recognition to clock in, but both methods have shortcomings. The way of swiping the card cannot prevent the phenomenon of punching the card on behalf of the card, and the fingerprint recognition method can prevent the phenomenon of punching the card on behalf of the card, but the physiological characteristics of each person are different, so some people with clear fingerprints can easily punch in the card, while some fingerprints are not clear. Or it is difficult for people with hypothermia in their fingers to punch in the card, so there is a defect of repeatedly punching in the card, and the attendance machine also has the deficiency of single function. Contents of the invention [0003] The purpose of the present invention is to provide a...
