Abstract

The invention discloses an ultra high frequency radio frequency identification (UHFRFID) technology-based campus real-time anti-theft system. The conventional campus anti-theft system lacks of real-time property and has high human factor. The system mainly comprises a plurality of UHFRFID passive tags and a plurality of UHFRFID detection devices; the UHFRFID passive tags are divided into article tags and owner tags which respectively mark articles and article owners; and the detection devices are arranged at all entrances and exits of a campus. When an article is carried out of the campus by a non-owner (such as a thief), namely an article tag enters a signal coverage range of a detection device when the corresponding owner tag is absent, the detection device can detect and alarms in real time. The system is mainly used for alarming in real time when non-small valuables of the campus, such as laptops and bicycles, come in or go out of the campus abnormally, and can implement automatic high real-time campus anti-theft monitoring.

Description

Campus real-time anti-theft system based on the UHFRFID technology

Technical field

The invention belongs to the electronic anti-theft field, be specially a kind of campus real-time anti-theft system based on the UHFRFID technology.

Background technology

The campus is antitheft has scope large, and the characteristics that flow of the people is large cause its difficulty high, and loss is large.At present antitheft human factor is larger, lacks real-time, is difficult to recover stolen article then and there normally based on video monitoring and labor management in the campus, more often just is used for giving a clue afterwards.

Radio-frequency (RF) identification is called for short RFID, is exactly automatically to identify by the technology of the people of label or thing by radiowave.Along with the RFID(radio-frequency (RF) identification) the developing rapidly of technology, it is ripe that the remote-wireless identity recognizing technology is tending towards, the RFID technology is also more and more in the application aspect antitheft, mainly contain following several: (1) is similar to the EAS(eas system) theft-prevention applications, by embedded RFID label on commodity, leave the market when it is improper, through detector means (mostly being a shape) time, the meeting trigger alarm, thus remind cashier, client and market security personnel in time to process; (2) aerial signal that connects of reader covers whole antitheft zone, and when the article of embedded RFID label left antitheft zone, system can find alarm in real time.But it is large both can't to satisfy the antitheft scope in campus, the characteristics that flow of the people is large.

Summary of the invention

In view of this, the present invention proposes a kind of campus real-time anti-theft system based on the UHFRFID technology, be used for the non-minitype precious article in campus, as the Real-time Alarm in the improper discrepancy such as notebook computer, bicycle campus, can realize the campus anti-thefting monitoring of automatic high real-time.

The technical scheme that technical solution problem of the present invention is taked is:

System mainly comprises a plurality of UHFRFID passive labels and one or more UHFRFID pick-up unit.Label is divided into article tag and owner's label, difference these article of mark and these article possessor, pick-up unit is placed in each gateway, campus, when article are carried when leaving the campus by non-its possessor (as thief etc.), namely when article tag not on the scene and when entering the pick-up unit signal cover, pick-up unit can detect and Real-time Alarm at its corresponding owner's label.

Described pick-up unit comprises UHFRFID reader, at least one reader antenna that is connected with reader and Back end data processing unit.

Described article tag and owner's label are the UHFRFID passive label, get the least-significant byte decimal number and be used for coding in the storage area able to programme of each label, wherein high 4 0000～9999 represent 10000 different users, in low 4 0000～9999,0000 represents this user itself, and 0001～9999 represents the article that this user is different.

Described article tag packaging technology is the paster form, and the front is pattern, and middle part, the back side is the UHFRFID passive label, and back side periphery is adhesive label, can be attached on the main stolen article in campus such as notebook computer, bicycle, has good disguise.Article tag should be avoided directly contacting with metal material.

Described owner's Tag Packaging is paster form or card form, and the possessor carries by article.

Described Back end data processing unit is the computer software for the antitheft exploitation in campus, according to described label coding building database, store owner's information corresponding to this label coding, as name, student number, contact method etc., or Item Information, as title, picture etc.

Described Back end data processing unit is completed following function after obtaining the label information that reader reads: judge 1. whether this label is article tag; If 2. this label is article tag, judge whether its corresponding owner's label is on the scene; If 3. its owner's label is absent from the scene, take following action: audible and visual alarm, and eject pictorial information and holder's information thereof of the corresponding article of this article tag; 4. record article and come in and go out constantly, be used for checking when needing.

Embodiment

The invention will be further described below in conjunction with accompanying drawing.

The present invention includes a plurality of UHFRFID passive labels and one or more UHFRFID pick-up unit.As shown in Figure 1, a UHFRFID pick-up unit comprises UHFRFID reader, at least one reader antenna that is connected with reader and Back end data processing unit, the UHFRFID passive label is divided into article tag and owner's label, and article tag and owner's label are for one to one or many-to-one mapping relations.

Described article tag packaging technology is the paster form, as shown in Figure 2, the front is pattern 2-1(such as cartoon pattern), middle part, the back side is UHFRFID passive label 2-3, back side periphery is adhesive label 2-2, can be attached on the main stolen article in campus such as notebook computer, bicycle, have good disguise.Article tag should be avoided directly contacting with metal material.

The invention will be further described to use flow process below in conjunction with system:

The first step: set up the reception centre, mostly be campus security section.Need the user (student or teacher etc.) of this system service to carry its article and register in the reception centre, the reception centre gives its packaged owner's label and article tag, and records corresponding informance in computing machine place building database.As, owner's label coding of the student of first registration is 0,000 0000, record this student's name student number contact method and corresponding with this numbering in database, the article tag of first article of this student is encoded to 0,000 0001, the title and picture and corresponding with this numbering of these article of storage in database, the article tag of second article of this student is encoded to 0,000 0002 by that analogy; Owner's label coding of the student of second registration is 0,001 0000, by that analogy.

Second step: use the user of this system that owner's label is affixed on or is placed in carry-on articles, as wallet etc., guarantee that owner's label carries, and article tag is affixed on registered article, make label try one's best hidden not directly and Metal Contact.

The 3rd step: pick-up unit is set up in each gateway in the campus, i.e. reader, be connected with reader 2 or 4 antennas (one-sided or bilateral) and computing machine (most cases is that school safeguards the computing machine in the chamber) that this system software has been installed.The aerial signal coverage rate is typically about 10 meters, dead ahead sector region, guarantees that signal covers the school gate gateway.

The 4th step: the database of first step foundation is shared to the pick-up unit of each gateway, due to the user who has follow-up registration, need to guarantee the regular update database.

The 5th step: enter normal detected state, as shown in Figure 3, when and if only if user's article are come in and gone out school gate when it is absent from the scene, computing machine place audible and visual alarm, and the title and the picture that access these article inform the Security Personnel, and the Security Personnel can find and tackle a suspect.
