Abstract

The invention provides a self-service item management system based on RFID. The system comprises a central controller, a management sub system, a monitoring sub system, an alarm sub system, a self-help use sub system and a printer. The central controller intensively processes data information submitted by each sub system and sends control commands. According to the invention, an RFID intelligent recognition technology whose band is 2.4Ghz is used to carry out full supervision of a complete life cycle, which comprises use, return, monitoring, inventory, repair, scrap and the like, on items; through the system, the use flow of a device can be effectively tracked in real time; device positioning and searching are convenient and fast; the procedures of device use and return are simplified; the utilization rate of the items is improved; and in addition, the system further gives an alarm if the device is illegally taken out.

Description

A kind of self-service Articla management system based on RFID

Technical field:

The present invention relates to intelligent monitoring and management domain, relate to specifically radio frequency active label technique is applied in monitoring of tools management system.

Background technology:

The equipment of the units such as school, enterprise, scientific research is generally to belong to shared device, in a lot of situations, be that one or several equipment are used jointly by many people, how to realize keeping properly and rationally using of equipment, improve plant factor and serviceability rate, allowing existing equipment bring into play maximum efficiency, is the core objective of Item Management work.Traditional Item Management carries out according to manual type, exist plant maintenance not in time, cannot fast finding, inner use circulation not convenient, can not prevent illegally the taking out of of equipment, cannot understand in real time the service condition of article, thereby cause plant factor low.For this situation, some units have taked certain control measures, as online booking, equipment are used registration etc., although improved to a certain extent the utilization factor of equipment, but can not realize the automatic management of life period of an equipment, cannot stop illegally taking out of of equipment, the current end user of positioning equipment and position, cannot fundamentally stop the various drawbacks that labor management exists fast.

According to above situation, must take advanced person, safe and reliable intelligent management system to strengthen the management to article, by each equipment of RFID technology identification of application of advanced, realize the management of equipment Life cycle from bringing into use to scrapping, particularly simplify the flow process that article are used circulation to check-in, provide fast, equipment lookup method intuitively, prevent that the equipment of not going through the formalities is moved out of, use order that can reasonable arrangement equipment, meet the emergent demand that equipment is used, the utilization factor of raising equipment, the serviceable life of extension device.

At present based on RFID (Radio FrequencyIdentification, radio-frequency (RF) identification) the source technology that has has been used in location, tracking and the management domains such as article, personnel, with its noncontact, response rapidly, the advantage such as colony's identification, mobile identification, the transfer of label side, simplify workflow, improve level and the efficiency of article and personal management.Article monitoring locating device based on RFID to articles seeking, location, monitor, make an inventory, receive, give back, the link such as maintenance realizes automatic data collection, guarantee that article, in instantaneity and the accuracy of each link input data, improve the integrated management level to article.

Summary of the invention:

In order to improve Item Management level, reasonable disposition article resource, the present invention has announced a kind of self-service Articla management system based on RFID, use the present invention can grasp in real time the use state of equipment, the complete life cycle management that realization is received, gives back, monitors, makes an inventory, keeped in repair and scrap etc. article, improves the utilization factor of article and integrated management level.

A self-service Articla management system based on RFID, this system comprises central controller, ADMINISTRATION SUBSYSTEM, self-service use, system, acoustic-optic alarm, RFID monitoring locating device and printer.

ADMINISTRATION SUBSYSTEM comprises the anti-transfer electronic tag for the unique identification of equipment, for issuing read write line and the PC of anti-transfer electronic tag; Wherein, anti-transfer electronic tag is together with apparatus bound, and read write line is connected by netting twine with PC, and PC is connected by netting twine with central controller;

Self-service use subsystem comprises the personnel's card for the unique identification of personnel, for the read write line of identification personnel card, for identifying the read write line of having bound anti-transfer electronic tag equipment, computer; Wherein, personnel's card is used by personnel, and read write line and the computer expert of personnel's card reader, anti-transfer electronic tag cross netting twine and be connected, and computer is connected by netting twine with central controller;

Be used for equipment and illegally take the exit passageway that the acoustic-optic alarm of warning is placed on article storage space out of, by cable, be connected with central controller;

For monitoring, the RFID monitoring locating device of positioning object is arranged on article storage space, by netting twine, be connected with central controller;

The printer of going out to receive voucher for printing device is connected with central controller.

The present invention has used based on RFID multiple goal real time recognition, and the identifying information each subsystem being obtained by central controller carries out collective analysis and processing

Accompanying drawing explanation:

Fig. 1 is the schematic diagram of false-proof authentication system three parts

Fig. 2 is that common radio-frequency identification reader carries out the process of anti-fake certificate to label

Between Tu3Shi authentication center and radio-frequency identification reader/writer about tag recognition key transmittance process

Fig. 4 is the radio-frequency identification reader/writer exemplary block diagram that realizes anti-fake certificate function

Embodiment:

With reference to the accompanying drawings, provide a kind of easy specific implementation of the present invention.

Radio frequency label read-write machine, except having normal RFID label read-write capability, also leaves USB Host interface, and with the communication interface of internet.

Anti-fake certificate center is installed on corresponding PKI public key certificate and the private key of read write line in USB Key, is distributed to corresponding read write line user.

User, before radio-frequency (RF) tag is authenticated, opens internet communication interface.Read write line YuPKI CA carries out certificate two-way authentication in center.

The article mark information of radio frequency antifalsification label is read in authentication by rear read write line, article mark information exchange is crossed to communication link and pass to backstage authentication center.

Authentication center obtains, after false proof article mark information, searching corresponding authenticate key in its database.

Authentication center according to the PKI in false proof read write line certificate using authenticate key as plain text encryption.By communication link, pass to read write line.

Read write line imports this ciphertext in USB key.

USB key with its preserve private key by decrypt ciphertext, obtain authenticate key.

Read write line more with reference to the accompanying drawings key derivation shown in 2 complete the authentication to antifalsification label.

Module described herein and unit both can adopt hardware to realize, and also can adopt software to realize, or the array mode of software and hardware realized.The present invention is not limited to above-described embodiment, and those skilled in the art are understood that and can make within the scope of the present invention the change in various forms and details.
