Design of a multifunctional entrance guard system using GSM and fingerprint identification

Abstract

Conventional entrance guard systems have monotonous functions. This paper designs an entrance guard system that takes the STM32 single chip machine as the control center and has the fingerprint identification module, GSM short-messaging module, the call notification module to realize local and remote unlocking (door opening) operations. Touch display screens and the STemWin graphics software are combined to design the human-computer interaction interface. The external memory module is designed to record the unlocking time and the historical data about the door opener. This designed system has diverse functions, secure, convenient for operations and can realize visualization of human computer interaction.
