Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Referring to accompanying drawing 1, accompanying drawing 2, supermarket shopping accounting device of the present invention comprises server, switch, main PC, sales counter PC 1, sales counter PC 2, sales counter PC N (N is a natural number, can be provided with according to the supermarket scale), the gateway PC, touch-screen display, first read write line, card reader, printer, second read write line, warning device, label detecting antenna, gateway antenna, decoding case.The sales counter PC is two-way is connected with each by interchanger for server, and exchange message realizes sharing database.Main PC mainly is to realize total system is managed operation for the supermarket managerial personnel.Sales counter PC 1, sales counter PC 2 ..., sales counter PC N is the control section of self-checkout system, they respectively with one first read write line, a touch-screen display, a card reader, printer links to each other; Wherein first read write line connects a label detecting antenna to read the label information on the commodity in the decoding case.Be provided with the travelling belt 105 that width is slightly less than decoding case width by upper level in the middle of the decoding case, this travelling belt is in the past backward respectively around final drive shaft 101, form rectangular closed drive mechanism up and down from transmission shaft 104, is horizontally disposed with the flat board that itself is label detecting antenna between the travelling belt of rectangular closed drive mechanism up and down at this; Front portion above the decoding case has label throwing mouth 107 travelling belt in case and moves the position, top, be used for throwing the PVC label, the PVC label of input is read after the information by label detecting antenna flat board 106 with travelling belt reach and moves end from travelling belt and fall into the decoding lower box part and concentrated and reclaim.
Travelling belt 105 can be driven by the motor 103 through variator 102 speed changes by final drive shaft 101 and rotate, client realizes control by the sales counter PC to motor 103 by touch-screen display, travelling belt 105 just begins to rotate after clicking START button, and client throws into the PVC label on the travelling belt by label throwing mouth 107 and read information by label detecting antenna flat board 106.Treat that all label informations of client are read and fall into the decoding lower box part, click " withdrawing from " button, travelling belt just stops operating, and continues the identification of next bit client to putting into label then.The present invention's box structure of decoding is in order better Commercial goods labels to be put into the recognition scope of antenna for client when paying dues and to be helped that label reclaims automatically and design.For the mutual interference mutually of the aerial signal that prevents from the adjacent checkout system to link to each other with read write line, the placement of each accounting device decoding case needs at a distance of certain distance.
The gateway detection system is that the gateway PC is controlled second read write line and constantly detected in the UID of the label by EXIT and the merchandise news table of having paid dues from database by the gateway antenna and search, if do not have corresponding merchandise news (promptly these commodity are not paid dues), then send audio alert by warning device.Wherein warning device be by the MSP430F169 single-chip microcomputer be core realize voice guard.
For preventing the selected commodity of client because volume is big or the more and difficult decoding case of putting into simultaneously of quantity, every the commodity in supermarket are all pasted two RFID labels, wherein one is soft label, one is the PVC label, the UID of these two labels (unique identifier) is to same commodity in should the supermarket, first read write line reads in the UID of PVC label when paying dues, and the UID with soft label after paying dues writes the merchandise news table of having paid dues in the database by sales counter PC 2.Wherein soft label is (can not arbitrarily take off) that is attached to the commodity surface, and the PVC label is (can arbitrarily take off) that is attached to the commodity surface by the mode that hangs or paste, and pays dues and finishes the back recovery to reduce expense.
The checkout system of controlling with sales counter PC 2 below in conjunction with accompanying drawing 3 is that example is elaborated to the self-checkout flow process.Client is after choosing article, take off and put into the decoding case being attached to PVC label on every commodity, because label overlaps fully and will bring bigger influence to the identification of first read write line, so the mode that should adopt relative dispersion to put into when putting into the decoding case is designed to the once concentrated label of putting into of the slot-shaped client of avoiding so decoding case label is thrown mouth 107.Make read write line can read many PVC label informations simultaneously by using anti-collision technology, the information of the selected commodity of client can be read in by " once ".When client clicks " scanning " button on the touch-screen display, sales counter PC 2 controls first read write line reads the UID that client puts into decoding case PVC label by the label detecting antenna plate 106 in the decoding case, and from database, extract the information (price etc.) of corresponding goods, calculate all article total prices that client puts into the decoding case, for having prevented that label is by skip, first read write line shows the quantity of all kinds of commodity of transaction this time by touch-screen display after reading in label information, unit price, total price, wait for that client confirms, after client confirms, the prompting client inserts member card, read in information of member card by card reader, and the prompting user inputs password, detect whether it correct, if it is correct, whether enough, if enough continue the check-out flow of back, i.e. amount deducted if then detecting user balance, increase integration etc.
After above operation was finished, sales counter PC 2 was put into the database merchandise news table of having paid dues with the soft label UID of paying dues commodity correspondence, and prints this Transaction Information.After above self-checkout was finished, label falls into decoding case bottom automatically by travelling belt 105 just can be concentrated recovery.Because the UID of these PVC labels that are recovered can not deposited in the merchandise news table of having paid dues in the database, thus concerning the gateway detection system the label of article of not paying dues, so these labels can not be taken out of the supermarket.The gateway PC is controlled second read write line and is read UID by the soft label on the commodity of EXIT by the gateway antenna always, and search in the merchandise news table of paying dues in database, if can find detected UID (being that corresponding goods is paid dues), then allow to pass through, and paid dues corresponding goods information in the merchandise news table of deletion, to reduce the database data amount; Otherwise, send audio alert by warning device, realize antitheft.
Because client deleted in the merchandise news that client bought is being paid dues the merchandise news table when leaving the supermarket, so client directly carries the commodity of buying once more when entering the supermarket and leaving, the gateway warning device will send alerting signal, and this can enter the supermarket by the article that directly do not carry firm purchase gateway, supermarket writeprompt information reminding client and solve.
Because metal, liquid etc. will exert an influence to reading of second read write line, wherein to the influence of ultrahigh frequency greater than high frequency.In addition, ultrahigh frequency also greater than high frequency, therefore, has selected for use high frequency 13.56MHz as frequency of operation to the injury of human body among the present invention, adopts the ISO15693 agreement.But metal, liquid etc. still can exert an influence to the correct detection of gateway detection system, and the method that can adopt tradition checkout demagnetization method to combine with the present invention overcomes the above problems.The article that are about in the supermarket are divided into two classes, and a class is to use traditional paying dues and demagnetization method; The another kind of self-service accounts settling method that the present invention is based on radio-frequency (RF) tag that adopts exactly, at this moment client only need detect just by two gateways when leaving the supermarket, and one is that traditional gateway detects, and the gateway as soft label UID of the present invention detects.Can partly solve the supermarket queuing problem like this, reduce supermarket operating cost.If in article brand shops such as native system application and clothes, footwear,,, accomplish the end in view so native system can directly be used because that these article influence the recognition of read write line is very little.
