Lock switch method of intelligent electronic lock system with UHF radio frequency identification function

Abstract

The invention discloses an intelligent electronic lock system with an ultrahigh frequency radio frequency identification function as well as unlocking and locking methods of the intelligent electronic lock system, wherein the intelligent electronic lock system comprises an intelligent electronic lock and a background system, wherein the intelligent electronic lock comprises a mechanical lock, a micro motor, a microcontroller, an electronic tag and a battery, the background system comprises a reader-writer and a background computer, the background computer reads a memory area of the electronic tag through the reader-writer, the state of the mechanical lock is determined, and in addition, a control command is written into the memory area of the electronic tag; the microcontroller obtains the control command from the memory area of the electronic tag, the on-off state of the electronic lock is detected, the micro motor is driven to take locking and unlocking actions according to the control command, and in addition, the state information of the electronic lock is written into the memory area of the electronic tag. The system solves the problems that the disposable electronic lead seal cannot be repeatedly used in logistics industry in the prior art, and the operation cost is higher.

Description

technical field [0001] The invention relates to an intelligent electronic lock system, in particular to an intelligent electronic lock system with an ultra-high frequency (UHF) radio frequency identification (RFID) function and a method for opening and closing the lock. Background technique [0002] In the logistics and transportation industry, the safety of goods is an important issue that both the sender and the receiver are concerned about. During the transportation of some high-value goods, the driver may collude with criminals to destroy the locks, steal the goods or replace the goods, and then restore the locks to cover up their theft, causing losses to the sender and receiver. The traditional prevention method is the combination of civil air defense and lead seals on the locks. However, the lead seal process is simple and easy to imitate. It must invest a lot of labor costs for supervision, and it is difficult to prevent losses during transportation. [0003] With th...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an intelligent electronic lock system with ultra-high frequency radio frequency identification function and its switch lock method, which is used to solve the problem that the disposable electronic lead seal cannot be reused and the operating cost is high in the current logistics industry, and at the same time Compatible with the 800 / 900MHz passive UHF radio frequency identification system widely used in the logistics industry, reducing the construction and operation costs of the logistics management system
