The Design of PLC Entrance Guard System Based on RFID Technology

Abstract

With the rapid development of social economy and science and technology, rfid technology is more and more widely applied in various industries, especially the identification and security industries, entrance guard system as an important unit of the intelligent building is more and more get attention. This paper designed a kind of using RFID technology the high security of the intelligent entrance guard system, is through the RFID authentication fast confirm the identity of the intelligent entrance guard system. Based on the analysis of the elevator entrance guard system functional requirements, the PLC elevator entrance guard system based on RFID technology for the function modular design. The system has extensibility, for subsequent higher security requirements provide a solution that can be applied to the elevator internet of things development needs in the future.
