Described RFID electronic tag all has unique UID, and this data user can not revise, and in some read-only application, can utilize it to provide sign for article.
The TCP/IP mode is adopted in described system database and the communication of POS machine, and the standard of following is IEEE802.3.
Be divided into 64 in the card of described RFID electronic tag, 4 byte/block, the capacity of totally 256 bytes.
A kind of data, the invention has the advantages that owing to adopt above-mentioned structure in the backup access method of RFID electronic tag: 1, realize user data access in the RFID electronic tag, information comparison checking and management work; 2, can the data of card storage inside be backed up
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments;
Fig. 1 is the synoptic diagram of a kind of data of the present invention in the backup access method read-write process of RFID electronic tag.
Embodiment
The present invention is based on the information storage tube reason of RFID, it is characterized in that effectively realizing that the rfid card internal data is carried out the access checking to be checked, guarantees that information is accurate, and has backup functionality and the efficient recovery data function is arranged.Prevent information maloperation and corrupted data on the RFID electronic tag, carry out the valid data backup.
For improving information data security on the electronic tag, read by RFID electronic label read-write circuit, write main the application and backup access information method on the RFID electronic tag, communication interface controller by special use and data are handled to be connected with R-T unit and are carried out data communication, and by wired or wireless mode information is delivered to central database at a distance and handles, can understand institute's recorded information and the true and false on the RFID label timely, also can record information to special data piece on the RFID electronic tag as required, realization is carried out valid memory access to the RFID internal data, when reading critical data, needs checking inspection data are compared, guarantee that information is accurate.This is a kind of practical convenience, the rational message exchange disposal route of simplicity of design.
As shown in Figure 1, the present invention is when the storage service data, the card UID sign indicating number of reading the RFID electronic tag identifies as the RFID electronic tag, compare with current POS machine temporal information and RFID internal time information character string, and data are decrypted computing, check RFID electronic tag sign validity, after validity check, be encrypted computing with user's real consumption information, form ciphertext and deposit RFID electronic tag sign specified data block and standby block (address) in, user's real consumption information is imported system database into by the POS machine of networking simultaneously, and records the information character string of current time in electronic tag; When reading business datum, the UID sign indicating number of reading the RFID electronic tag identifies as the RFID electronic tag, check RFID electronic tag sign validity, after validity check, read the data that are stored in RFID electronic tag sign assigned address and standby address, be decrypted computing with the fund information of user's actual storage, compare errorless, read RFID electronic tag fund, carry out service data manipulating.
A RFID electronic tag storage space that meets the ISO15693 standard has the label of 2Kbit, 4Kbit capacity, the label of a 2Kbit capacity, they are divided into 64 blocks in logic, each block has 32 bit, namely 4 byte can preserve 4 ascii characters, and data block is the least unit of electronic tag accessing operation, each read-write operation is all wanted intended target piece number rather than byte or bit.In addition, each RFID electronic tag has unique UID in addition, and this data user can not revise, and in some read-only application, can utilize it to provide sign for article.Use in a plurality of fields need carry out unified planning to the electronic tag storage unit; rationally utilize; to carry out redundancy backup to significant data; protect internal information; planned that data allocations and data encryption have been to use enterprise's all-purpose card key, reasonably use DSFID can expand the application of electronic tag.
Data are in the concrete mode of backup access method of RFID electronic tag:
Card UID code data at first was present in the gate control system database when one, neocaine was handled, and sent in the consume system database newly-increased record in " worker's Basic Information Table " together with this card possessor's relevant information.
Two, carry out the dinning card initialization by the related personnel for the worker of enterprise, in card, write the sign of this consume system, so that top-up machines and charge machine identification.After this, the worker can supplement with money in the top-up machines of arbitrary dining room networking voluntarily.Supplemented with money only once in every month, and can supplement with money in arbitrary time in this month.With information return data storehouse, write and supplemented sign this month with money after supplementing with money.
Striding the moon supplements with money: do not supplement with money this month as for some reason, when supplementing with money next month, volume did not write worker's consumption card in the lump after system can supplement last month with money.
Three, consume system at first will be connected to the dining room from network node with network, its less important front end consume system of setting up, and it comprises consumption terminal, top-up machines, communication controller and computing machine.Network system: network system is the data transfer platform of dining room consume system, and native system adopts double-layer structure, database centered by the ground floor, be responsible for the preservation of all data and each subsystem data synchronously.The second layer is the consumption management machine, is responsible for charge machine and the communication of top-up machines and the preservation of local data.Each dining room directly or indirectly is connected to nearby host node by optical cable, inserts dining room consumption private network.Central database and secondary consumption management machine system communication adopt the TCP/IP mode, and the standard of following is IEEE802.3.
When four, the worker has dinner consumption, confirmed the corresponding amount of money of deduction from dinning card by dining room staff's button.The consumption record is stored in the charge machine, uploads to the local management PC during networking automatically, and is uploaded to the consume system central database via synchronization program.
Five, card internal data structure: the worker Ka Nei of enterprise has 64,4 byte/block, the capacity of totally 256 bytes.Operation to the RFID electronic tag is that unit carries out reading and writing with the data block, for guaranteeing the safety of data in the card, need to read deciphering, and writing needs to encrypt.
Six, shown in the data block information slip one that master data and backup access method are used in the card:
Table one
The present invention can realize effectively that the rfid card internal data is carried out the access checking to be checked, guarantees that information is accurate, and has backup functionality and the efficient recovery data function is arranged.Prevent information maloperation and corrupted data on the RFID electronic tag, and by POS machine less radio-frequency sensing device senses RFID electronic tag, data manipulation situation of RFID electronic tag etc. is recorded in the center management system, to grasp the information state of RFID electronic tag, user-friendly, prevented data simultaneously by improper use or damage, realized consuming the information security of having dinner and reliably reach fully automated management.By the present invention, can realize critical data valid memory access and backup in the RFID electronic tag, reach the effect of duplicate protection with this.
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
