Admission Notice Bluetooth Key Control Circuit and Application

Abstract

The invention discloses a bluetooth key control circuit and application of an admission notice, including a casing, a PCB board, a status indicator light, a switch button, a 2032 battery and a front cover. There are status indicators installed on the back of the PCB board, the Bluetooth control circuit is printed on the back of the PCB board, a switch button is installed on the back side of the PCB board, and a 2032 battery is embedded in the front corner of the PCB board. Contact, the outer edge of the back of the front cover is snapped with the outer edge of one side of the shell; the invention integrates artistry, technology and practicability, conforms to the IEEE802.15 standard, supports the Bluetooth 4.0 standard, and prints the traditional paper admission notice. The identification information is electronically stored in the Bluetooth control circuit chip of the PCB board, and then matched with an artistic shape to form a Bluetooth electronic key, which can communicate with the mobile terminal, check the electronic admission notice through the mobile terminal, browse the registration instructions for new students, and learn about the school. information.

Description

technical field [0001] The invention relates to the technical field of bluetooth keys, in particular to a bluetooth key control circuit and application of an admission notice.

Problems solved by technology

[0005] However, the identification information of the traditional paper admission notice is printed and stored, and its information accuracy, security, and uniqueness are poor, and the information carrying capacity is small. Limited by the paper carrier, it is difficult to fully reflect the architectural style of the school. , Humanities, history and teaching characteristics, and insufficient artistic atmosphere and sense of technology, unable to meet the enrollment needs of the new era, paper admission notices are easily damaged, lost, inconvenient to carry, do not have information interaction functions, poor security and practicability
