Abstract

The utility model discloses a travelling basket locking device based on NFC, NFC development board, antenna, treater UNO, singlechip, electric control lock, display adopt packaging technology to install on the travelling basket with the form of box lock. The nucleus module of NFC development board is the NFC chip, and this RF chips passes through realization of radio frequency induction principle and user's data interchange, can discern the NFC label, and read information realizes NFC development board and treater, communication through the I2C interface to then deliver to MCU processing with information. The on off state of locking is controlled to the information of the NFC label that treater processing NFC chip read, passes through the internet access through signal converter interface and singlechip. The electric control lock is the electric actuator who carries out the switch. The display demonstration comes from user tag information. It is efficient to unblank, and artificial intelligence ization has been solved the password and has been forgotten the problem of bringing, the NFC label low cost of adoption, economic environmental protection.

Description

Suitcase locking device based on NFC

Technical field

This utility model relates near field wireless communication technique (NFC) field of radio frequency identification, is specifically related to a kind of suitcase NFC radio-frequency unit of intelligent and safe switch-box in long-distance trip.

Background technology

The long-distance trip of people or tourism or go on business, all can't do without the luggage case of the article such as accommodating laundry, file, and the trip that it is us brings the biggest convenient.But because the case lock of suitcase also brings a lot of worry to us, travel suitcase lock experienced by the development of the coded lock from the simplest clumsy key lock more fashion till now.No matter current password locking device, be to use instrument, or net passes luggage case half a minute unblock treasured book, does not also have antitheft effect.Even more important problem is forgetting Password of often occurring of coded lock or situation that misoperation causes coded lock to damage, and these all illustrate the defect that current travel case case is latched in.

Summary of the invention

Technical problem to be solved in the utility model: provide a kind of intelligent box locking device based on NFC technique, this case lock can such as possess mobile phone or the IC-card of NFC function by sensing NFC label, it is achieved unpacking and lock box operation of suitcase.

This utility model solves its technical problem and the technical scheme is that and include NFC development board, antenna, processor, signal adapter, single-chip microcomputer, electric control lock, display.The form that NFC development board, antenna, processor, single-chip microcomputer, electric control lock, display use packaging technology to lock with case is arranged on suitcase.The nucleus module of NFC development board is NFC chip, and NFC chip realizes the data with user by radio frequency induction principle and exchanges, and can identify NFC label, read information, realizes NFC development board and processor communication by I2C interface, thus information is then delivered to single-chip microcomputer and processes.Processor processes the information of the NFC label that NFC chip reads, and controls the on off state of lock, is connected by network with single-chip microcomputer by signal adapter interface.Electric control lock is carried out the electric operator of switch.Display shows from user tag information.

By such scheme, described processor uses processor Arduino UNO.

By such scheme, described signal adapter uses RS-232 signal adapter.

This utility model, compared with conventional art, has a following main advantage:

1. use near field communication, use the Intelligent key (such as having mobile phone or the IC-card of NFC function) containing NFC label to can be achieved with unpacking near case lock, compensate for inefficient the unblanking of traditional mechanical key or coded lock.

2.NFC chip realizes the data interaction with user according to radio frequency induction principle, can be with the information of identification card, single-chip microcomputer processes information and controls the switch of electric control lock by issuing a command to processor Arduino UNO under network, whole " invisible " process of unblanking is manual intelligent for manual operation password unlocking, thus solves password and forget the problem brought.

3., because of the maturing of label technique, the NFC label of employing is with low cost, economic and environment-friendly.

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.

NFC development board that this utility model hardware configuration as it is shown in figure 1, include is fixedly installed on suitcase, processor Arduino UNO, signal adapter, single-chip microcomputer, electric control lock, display.During unpacking, NFC development board contains the Intelligent key (such as having mobile phone or the IC-card of NFC function) that NFC chip contains NFC label according to radio frequency principle identification and completes operation of unpacking.

NFC development board RF identification possesses the mobile phone of NFC function or the card number of the IC-card containing NFC label and type, and its information can be read, it be by I2C interface with processor Arduino UNO communication, this NFC development board can use PN532NFC development board, or other possess the NFC development board of identity function.

Processor Arduino UNO core is ATmega328, has 14 railway digital I/O ports simultaneously, and wherein 6 tunnels can export as PWM, 6 tunnel simulation inputs, a 16MHz crystal oscillator, a USB port, one supply socket, an ICSP header and a SR.It processes the information of the label that radio frequency chip reads, the on off state of control chamber lock, is connected with single-chip microcomputer by RS-232 interface, and the information of preservation is delivered to single-chip microcomputer by processor Arduino UNO, it is achieved with the serial communication of single-chip microcomputer.

Signal adapter is then to connect processor Arduino UNO and single-chip microcomputer by RS-232 interface.

Single-chip microcomputer uses common PC, all unit is carried out central management and monitoring, adds accordingly, read, and revises, the work such as inquiry.Single-chip microcomputer processes and mainly completes two work: is on the one hand the information from processor Arduino UNO to be stored, on the other hand utilizes the input-output equipment such as electric control lock, display to show user profile.

Electric control lock is carried out the electric operator of switch.

Display is that display is from user tag information.

Work process of the present utility model is as shown in Figure 2, characteristic because of NFC development board, NFC development board is in resting state when starting, normal condition need to be initialised to, this instruction need not put card, when after the version number's success obtaining NFC development board, i.e. show to wake up the success of NFC development board up, it is then carried out operation of unpacking: " key " (i.e. the mobile phone containing NFC label or IC-card) locked near case, then wake up successful NFC development board up and read NFC tag information, these information are preserved by processor ArduinoUNO and to be uploaded to single-chip microcomputer etc. to be verified, then complete to unpack after single-chip microcomputer checking information is correct.In whole Case lock, single-chip microcomputer controls the switch of electric control lock by issuing a command to processor Arduino UNO under network, and case lock status, usage log, is all to be preserved by processor ArduinoUNO and be uploaded to single-chip microcomputer.
