Running sign-in device

Abstract

The invention discloses a running sign-in device which is characterized by comprising a semiconductor type capacitive fingerprint acquirer module, an illumination type heart rate detection module, an automatic power supply switching module, an LCD display module, a master control module and a database; the semiconductor type capacitive fingerprint acquirer module is used for acquiring fingerprint information; the illumination type heart rate detection module is used for measuring the heart rate; the automatic power supply switching module is capable of switching to battery power supply in power failure and providing voltage for the peripheral and the kernel of a DSP (digital signal processor); the LCD display module is capable of clearly displaying the information, the sign-in times and the running heart rate of a signer; the master control module is used for efficiently processing an input fingerprint image, extracting characteristic values, processing brightness pixel points, performing optimal estimation on a next state by using a kalman filter and effectively tracking the heart rate change, and used for comparing current data with data in the database so as to update the database. By adopting the device, the validity of the identity and the effectiveness of running of the signer are ensured.

Description

technical field [0001] The invention relates to a running sign-in device, which belongs to the field of automation. Background technique [0002] With the development of science and technology and the improvement of quality of life, many students have reduced their physical fitness level due to lack of exercise. Many schools advocate daily long-distance running to enhance their physical fitness for students who do not exercise enough. Running sign-in devices are widely used in colleges and universities. [0003] At present, the running sign-in methods on the market include stamp sign-in, RFID card swiping sign-in, and simple fingerprint form recognition sign-in. In order to meet the needs of some students to cope with the sign-in, various methods of fake sign-in came into being, using forged sign-in stamps, one person to swipe the RFID cards of multiple people, and using silicone fingerprint sleeves to swipe and other methods. Even the most advanced biometric radio frequenc...

AI Technical Summary

Problems solved by technology

Even state-of-the-art biometric radio frequency fingerprinting is not only expensive, there are new bionic fingerprint sleeves that can bypass sign-in devices

Therefore, a single identity verification cannot ensure the validity of the sign-in

Some institutions have invented a multi-identification sign-in device. Even if they can guarantee the sign-in, the effectiveness of running cannot be guaranteed. There are still quite a few students who ride instead of running or walk instead of running.
