Abstract

The invention discloses a device and a method for preventing a campus card from losing and forgetting. The device comprises the campus card and a card sleeve, wherein the campus card and the card sleeve are respectively provided with a transmitting circuit and a receiving circuit; a wireless transmitting module in the transmitting circuit is set to be in a transmitting mode; a wireless receiving module in the receiving circuit is set to be in a receiving mode; the transmission module is used for transmitting a radio-frequency signal to the receiving module; and when the distance between the campus card and the card sleeve exceeds a set safety distance, the receiving module can not receive the radio-frequency signal and then controllers on the campus card and the card sleeve simultaneously control buzzers to send out an alarm signal. Radio frequency chips nRF24L01 are used as wireless receiving and transmitting modules for receiving and transmitting signals; and when the distance between the campus card and the card sleeve exceeds a certain distance, the buzzers on the campus card and the card sleeve can send out alarm to remind a card holder of forgetting to take the card, and therefore the card is prevented from being lost.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a device and method for preventing loss and forgetting of a campus card. Background technique [0002] Human life has entered the era of card swiping, and various cards are inseparable in daily life: bus cards, campus consumption cards, and so on. We often encounter such a situation that bus cards and campus cards are often forgotten somewhere. Or they often forget to take the campus card from the card reader when they leave after swiping the card. If can have a reminding device just can solve this problem. With the development of induction technology, applying induction technology to ferrule can effectively solve this problem. Contents of the invention [0003] For this reason, the present invention proposes a campus card anti-lost and anti-forgetting device and method, and the present invention uses a wireless module to transmit and receive signals. Insta...
