Unlocking and locking method for NFC based security intelligent lock system

Abstract

The invention discloses an unlocking and locking method for an NFC based security intelligent lock system. The security intelligent lock system includes an intelligent lock, a mobile terminal, and a main station. The intelligent lock is provided with a MCU control module, the mobile terminal is equipped with a software operation module, the intelligent lock is in communication connection with the mobile terminal through NFC, and the mobile terminal is in communication connection with the main station. Through command sending of the mobile terminal and the secret key verification or information verification between the intelligent lock, the mobile terminal and the main station, secure unlocking and locking of the intelligent lock can be realized. The system has the characteristics of intelligence, convenient operation, security and reliability, and simultaneously due to adoption of the overall management and information storage functions of the communication network and the main station, the security intelligent lock system can effectively record and manage the unlocking and locking operation object, operation staff, object state, operation time and other information, and can update and upgrade the software part of the lock system so as to increase the security level. The system has strong adaptability and adjustability, and effective management of the lock system is improved.

Description

technical field [0001] The invention relates to an unlocking and locking method of an NFC-based safe intelligent lock system. Background technique [0002] At present, most of the homes, offices and other public places use ordinary key locks, identification card locks and fingerprint locks as security access control, which have the following shortcomings: (1) ordinary key locks and identification card unlocks cannot be effectively and accurately recorded. The current unlocker information, unlocking history information, etc., although the fingerprint lock can record the relevant information of the unlocker, but when the finger peels off, there is a problem that the unlocking operation cannot be successfully completed; (2) The anti-theft performance comparison of ordinary key locks Poor; (3) Once the lock is installed and formed, the security performance is also fixed, its software and hardware cannot be easily changed, and cannot be upgraded until it is old, damaged and repla...
