Embodiment Construction

[0025] The sign-in person stands on the weighing sensor (3), and gives the initial signal to the MCU, and the MCU prompts the sign-in person to put fingers and wrists on the detection site.

[0026] The fingerprint collector (8) collects the fingerprint of the sign-in person to complete the identity entry.

[0027] The reflective photoplethysmography acquisition unit (2) detects the wrist pulse wave, and the transmissive photoplethysmography acquisition unit (7) detects the fingertip pulse wave, obtains pulse wave waveforms at two positions, and synchronizes the collected data Transfer to MCU(4).

[0028] The gravity sensor (3) detects the weight of the sign-in person, and transmits the data to the MCU (4).

[0029] After the MCU (4) obtains the two pulse wave signals, the pulse wave transit time can be obtained according to the preset characteristic points, and the conversion of the pulse wave transit time into blood pressure is completed according to the stored calibration ...

Abstract

The invention relates to a fingerprint punched-card machine capable of detecting physiological parameters of a human body. The fingerprint punched-card machine basically comprises an MCU, a fingertip information acquisition unit, a reflection-type pulse oximeter signal acquisition unit and a weighing sensor unit, wherein the fingertip information acquisition unit consists of a fingerprint acquisition unit and a transmission-type pulse oximeter signal acquisition unit; the MCU, the fingertip information acquisition unit, pulse oximeter signal sensors and the weighing sensor are connected with one another; the fingerprint acquisition unit acquires the fingerprint information, attendance is finished, the two paths of pulse oximeter signal sensors acquire the pulse waves and transmit pulse waves to the MCU for performing blood pressure measurement; and the weighing sensor under the feet measures the weight information and transmits the information into a single-chip MCU. Meanwhile, a wireless transceiver module in the single-chip transmits the acquired information to a mobile phone and a computer, and the data is conveniently stored. According to the machine disclosed by the invention, fingerprint attendance can be realized, the blood pressure and weight data can be simultaneously measured, the data is transmitted into the detected mobile phone, and the physical condition of a person is conveniently known.

Description

technical field [0001] The invention relates to a fingerprint punching machine capable of detecting physiological parameters of a human body, in particular to a system capable of synchronously collecting blood pressure and body weight on the fingerprint punching machine. Background technique [0002] Fingerprint time card machine is the best way to evaluate employee attendance in large, medium and small enterprises in the 21st century. Employees go to and from get off work every day to complete the company's attendance requirements through fingerprint punching. Existing fingerprint unlocking machines have a single function and only realize time attendance. Under the background that modern enterprises continue to pay more attention to the health of employees, it is in line with the purpose of humanized corporate culture to monitor the physiological parameters of employees and understand the health status of employees while completing their attendance checks every day. In ad...
