Detailed description of the invention
With reference to the accompanying drawings the illustrative embodiments of the present invention is described in detail.Illustrative embodiments is retouched
State merely for the sake of demonstration purpose, and be definitely not the present invention and application thereof or the restriction of usage.
The subject matter that prior art exists is: need scanning repeatedly when having multiple commodity to scan or bundling commodity simultaneously
Time, the scanning of all commodity before scanning due to last commodity, only have read bar code information and search from data base
Rope to should the gravimetric value of bar code, immediately these commodity are placed in Weight acquisition module weighing, therefore can make
The collection value becoming weight is 0；And after last commodity is scanned, scanning before can not carried out the complete of Weight acquisition
Portion's commodity are placed in Weight acquisition module weighing, now, process according to existing method, can make the bar scanned for the last time
The commodity weight that code is corresponding is far smaller than the weight that Weight acquisition module gathers, and makes the PC of existing self-checkout system control mould
Block will the abnormal instruction of goods in transit, warning lamp lights, speech sound device reports that commodity are abnormal, touch display information prompting places
Commodity please check adjustment extremely, causes check-out flow to be interrupted.
To this end, the main thought that the present invention solves the problems referred to above is, after scanning last part bar code, then by more than one piece
Commodity or binding commodity are placed on electronic scale, now comparison to as if: the weight that whole bar codes of having scanned before weighing are corresponding
Value sum and the collection value scanning through the acquisition of Weight acquisition module for the last time are compared, and according to this comparison result, come
Judge that scanning is the most errorless, just can solve this problem.
Additionally, once occur that the gravimetric value that prestores that certain bar code is corresponding is adopted with weight present in prior art
When the Weight acquisition value of the collection actual acquisition of module is inconsistent, self-checkout check system soon sends abnormity prompt, interrupts knot
Account operating process.This situation occurs, the efficiency of checkout can be caused to reduce, bring bad purchase experiences, Yi Jizao to client
Become the queuing jam situation of self-checkout equipment.For solving this problem, the method for the present invention is, occur bar code pre-stored values with
When Weight acquisition value is not inconsistent, first temporarily only to relating to the whole labelling of commodity that is not inconsistent, it is not immediately terminated client and scans checkout
Operating process, client can continue to scan on next commodity.Only when client finally confirms checkout, self-checkout system can be reminded
Labeled commodity are checked oneself or are rescaned, verify by client, or directly notify that manager carries out hand inspection；If weight
Yet suffer from situation about not being inconsistent after new scanner uni verification, then manager can be reminded to carry out hand inspection for not being inconsistent commodity, as really
Fixed certain no problem, then logged in administration authority by manager and eliminate this exception indication of goods, make client can smoothly complete checkout.
For identical goods, the Different Weight situation that the reason such as Different Package or different size exists, can be in data base
Commodity for this bar code store multiple gravimetric values, in weight ratio relatively checking procedure, if Weight acquisition value and appointing of prestoring
One gravimetric value is consistent, so that it may by verification.
Concrete as in figure 2 it is shown, be the flow chart that verifies of self-checkout loss prevention of the present invention.After customer purchase, come
Before check out devices, the bar code of items scanning one by one.Wherein when scanning barcode, system obtains from the merchandising database in supermarket
Unit price that this bar code is corresponding and gravimetric value, this unit price and gravimetric value are and are prestored in merchandising database.In scanning single-piece
After bar code, the commodity scanned through are transferred to Weight acquisition module (such as electronic scale) and weigh, it is thus achieved that one actual
Measured value, if collection value is not 0, then compares the gravimetric value that prestores corresponding with bar code for Weight acquisition value (measured value),
According to comparison result, it is achieved the loss prevention verification of commodity.Result is divided into and is consistent and is not inconsistent two kinds of situations, if being consistent, represents scanning behaviour
Make normal, in the case of not confirming checkout, continue the scanning of next commodity；If not being inconsistent, then it represents that there may be asking of drain sweep
Topic, makes marks to the corresponding commodity relating to " not being inconsistent " in the case of not interrupting client operating.When client confirms checkout, self-service
Checkout loss prevention system can send prompting for this labelling to client, and now client can the most again be scanned and verify, or by managing
Reason person manually veritifies.If client scans the most again, verify, the result again scanned will cover before to labeled product
Scanning result, and with being as the criterion of again scanning, if after the most again scanning, system no longer makes a mark, then it represents that checkout operation
Errorless, can confirm that and complete checkout operation；Otherwise, if the most again being made a mark by system, then manually being veritified by manager, adjusting
After integral quotient product, manager logs in administrator right, removes labelling, makes client can smoothly complete checkout operation.Log in manager's power
The mode of limit, such as, can arrange the user name and password on the shopper checkout terminal unit of system, or by shopper checkout terminal
Device scan manager's condition code and logon rights, wherein the condition code of manager can be on the communication terminal device of manager
The Quick Response Code produced.
It should be noted that in reality, the corresponding multiple commercial specification of same bar code information or the feelings of packaging may be there are
Condition, at this point for identical bar code, prestores should multiple gravimetric values of bar code data base.If the weight that weight module obtains
The amount collection value gravimetric value that prestores with one of them is consistent, and can represent that scan operation is the most errorless.Additionally, also have some business in bulk
Product, mainly some agricultural product, such as vegetable, rice, beans etc., client is according to individual Man's Demands, or buys.And these business
Product do not have the gravimetric value of standard, it is impossible to say according to prior art, when commodity enter supermarket by standard weight corresponding for bar code
Amount is input in the equipment of Supermarket management data base prestore, also cannot be by the self-learning function of system, sweeping client
Retouch, in checking procedure self-teaching to preserve the gravimetric value that a certain bar code is corresponding.To this end, can be by bulk commodity weight-scale table and supermarket
Server communication connects, and while forming a payment bar code, is synchronized in data base enter by gravimetric value corresponding for this bar code
Row prestores, in order to taken out the object as comparison in shopper checkout scanning, checking procedure.
In the case of the bundled bar code (or scanning multiple commodity) of scanning, owing to scanning through wherein one every time simultaneously
After individual commodity, it is not immediately the sole product that this has just scanned through to be transferred in Weight acquisition module, therefore despite multiple
Scanning result, but in addition to last scanning, before Weight acquisition module is corresponding after scanning every time collection value be 0.This
The bright solution that proposes for this is, if when the gravimetric value that Weight acquisition module is measured is 0, the most now by bar code corresponding data
The gravimetric value that prestores in storehouse is accumulated on next commodity, and continues to scan on the next commodity bar in the more than one piece commodity of this binding
Code ... so, until after in the more than one piece commodity of this binding, commodity of last scanning are scanned, by the more than one piece business of this binding
Product are put in Weight acquisition module the Weight acquisition value obtained together and (multiple commodity prestore heavily the gravimetric value that prestores added up before
The summation of value) compare, according to comparison result, it is achieved the loss prevention verification of commodity.Result is divided into and is consistent and is not inconsistent two kinds of feelings
Condition, represents that scan operation is normal, in the case of not confirming checkout, continues the scanning of next commodity；If not being inconsistent, then it represents that may
The problem that there is drain sweep, then make marks to the corresponding entire service relating to " not being inconsistent " in the case of not interrupting client operating.?
When client confirms checkout, self-checkout loss prevention system can send prompting for this labelling to client, and now client can the most again
Scanning and verification, or manually veritified by manager.If client scans the most again, verify will cover before to labeled product
The scanning result of product, and with being as the criterion of again scanning, if after the most again scanning, system no longer makes a mark, then it represents that checkout
Process is errorless, can confirm that and complete checkout operation；Otherwise, if the most again being made a mark by system, then by manager artificial nucleus
After testing, adjusting commodity, manager logs in administrator right, removes labelling, makes client can smoothly complete checkout operation.Log in management
The mode of member's authority, such as, can arrange the user name and password on the checkout terminal equipment of system, or by checkout terminal equipment
Scanning manager's condition code.
Wherein, if the commodity of binding are M identical commodity, then, after the bar code scanning one of them commodity, read
Take the information of this bar code, and in the data base of supermarket, transfer the price of correspondence and the gravimetric value that prestores, then manual by input
After input M value, system by the price transferred with prestore after gravimetric value * M, then by the more than one piece commodity of this binding to Weight acquisition module
On, now the result of the gravimetric value * M that prestores is compared, according to comparison result by system with Weight acquisition value, it is achieved to self-service knot
The verification of account.So, can accelerate and the checkout operation sequence simplifying client.
Fig. 3 is the block diagram of self-checkout loss prevention check system of the present invention, as it can be seen, include that a shopper checkout terminal sets
Standby, it includes PC control module, and be connected with PC control module communication scan module, Weight acquisition module, input module,
