Wireless awakening active student label identification system and identification method thereof

Abstract

The invention relates to a wireless awakening active student label identification system, which comprises a portable student label and a card reader arranged at the gate of a school, wherein the student label mainly comprises a radio frequency module, a radio frequency antenna and a power supply module; and the card reader mainly comprises a radio frequency receiving module, a radio frequency transmitting module, a receiving antaean which is correspondingly connected with the radio frequency receiving module, a transmitting antenna which is correspondingly connected with the radio frequency transmitting module and a series port communication module. The card reader sends a wireless awakening signal all the time, the student label receives the wireless awakening signal when entering an effective action area of the receiving antenna of the card reader, sends the identity number and electricity volume information of the student label to the card reader and then enters a sleeping state. The identification system in the invention can solve the problem of abnormal record of a student forgetting to sweep a card when the student goes in and out of the school gate, avoids students from crowding and has a relatively high popularization and application value.

Description

technical field [0001] The invention relates to a radio frequency identification device, in particular to an information registration system for students entering or leaving a school.

Problems solved by technology

The disadvantage of this kind of passive radio frequency identification card is that students need to take the initiative to swipe the card when passing the school gate, but often students forget to swipe the card when entering and leaving the school gate, resulting in abnormal records of the student entering and leaving the school; and because of this type of card The communication distance with the credit card machine is generally not more than 10 cm, that is, it needs to be close to the card reader, and the reading speed is slow, so it is easy to cause congestion when the student flow is large
