Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] The optical key access control system includes a sending end and a receiving end, and the sending end sends signals to the receiving end.

[0030] Such as figure 1 As shown, the sending end includes a single-chip microcomputer STC89C51 and a key information sending end. The P2.0 port of the single-chip microcomputer STC89C51 is used as the output end, and a pull-up resistor R1 is connected to VCC. The P2.0 output is also connected to the gate of the field effect transistor as The key information sending end for sending data, the gate of the FET is connected to the P2.0 port of the single-chip microcomputer one, and the output state of the LED is controlled by the single-chip microcomputer one. The single-chip microcomputer encodes the information representing the identity, loads the encoded information to the LED through the single-chip microcomputer-P2.0 port,...

Abstract

The invention discloses an optical key access control system and a verification method thereof, belonging to the technical field of electronic communications. The optical key access control system comprises a sending end and a receiving end, wherein the sending end is used for sending signals to the receiving end; the sending end comprises a single chip microcomputer I and a key information sending end; the single chip microcomputer I is used for connecting a pull-up resistor R1 to a virtual channel connection (VCC); a grid electrode, connected with the single chip microcomputer I, of a field effect transistor is taken as the key information sending end for sending data; the grid electrode of the field effect transistor is connected with the single chip microcomputer I; the single chip microcomputer I is used for controlling the output state of an light emitting diode (LED). The central processing unit (CPU) card-based access control system effectively reduces the copying possibility of access control cards, thus greatly improving the safety. Furthermore, the access control system operation convenience for users and managers is greatly improved.

Description

technical field [0001] The invention relates to an optical key access control system and a verification method thereof, belonging to the technical field of electronic communication. Background technique [0002] With the continuous development of computer technology and communication technology, the access control system has become an indispensable part of the exit / entry management of enterprises, schools, and apartments. At present, most of the radio frequency card access control systems on the market use ordinary IC cards to open the door. Since 2008, German researcher Henrik Plotz and University of Virginia computer science Ph.D. Starting from the security algorithm of the classic chip, the traditional radio frequency card access control system has a huge security risk. Contents of the invention [0003] In order to overcome the above shortcomings, the present invention designs an optical key access control system based on visible light communication, which uses visibl...
