Description
Technical field
The present invention relates to a kind of self-service cash register weight method for monitoring and systems.
Background technique
Currently, some large supermarkets are provided with self-service checkout aisle both at home and abroad, by the self-service completion cash register of consumer and clearing
Process.However, supermarket staff cannot monitor the behavior of consumer in real time, flowed by the self-service completion cash register of consumer and clearing
Journey, inevitably occur the commodity after commodity are not scanned or scanned be replaced or barcode scanning demagnetization after delete kinds of goods and do not settle accounts demagnetization quotient
The case where product are taken away.
Summary of the invention
The present invention proposes a kind of self-service cash register weight method for monitoring and system, solves and is difficult to avoid that commodity in the prior art
Commodity after not scanning or scanning be replaced or barcode scanning demagnetization after delete kinds of goods and do not settle accounts the case where taking away demagnetization commodity.
The technical scheme of the present invention is realized as follows:
A kind of self-service cash register weight method for monitoring, comprising the following steps:
Step 1: self-service cash register is opened；
Step 2: the bar code of items scanning forms items list, and items list counts commodity number of packages and commodity weight；
Step 3: being placed on Weighing Area for the commodity after scanning at the appointed time and weigh, and Weighing Area detects and judges
Whether commodity number of packages and commodity weight match with items list, if so, entering in next step, otherwise alarm, callwork personnel
It is handled；
Step 4: if need to continue to do shopping, repeatedly step 2, if commodity, callwork need to be deleted from items list
Otherwise personnel's assist process enters in next step；
Step 5: being settled accounts for items list, terminates self-service cash register.
Preferably, in step 3, Weighing Area detect and judge commodity number of packages and commodity weight whether with items list phase
Match, specifically includes the following steps:
Weighing Area obtains weight change number and current weight, if weight change number is equal to commodity number of packages and current weight
Equal to commodity weight, then it is judged as matching.
Preferably, in step 3, judgement be placed on Weighing Area commodity whether be scanning after commodity, specifically include following step
It is rapid:
After the bar code of items scanning, the mobile detection of starting ultrasonic wave, with barcode scanning device to the horizontal displacement side of Weighing Area
To the commodity for for positive direction, locking current scanned bar code, the direction of displacement of the commodity is obtained, if the direction of displacement of the commodity
The projection fallen in the horizontal direction is positive, then concludes that the commodity for being placed on Weighing Area are the commodity after scanning.
Preferably, in step 3, judgement be placed on Weighing Area commodity whether be scanning after commodity, specifically include following step
It is rapid:
After the bar code of items scanning, start photographic device, capture commodity and be placed in the photo before and after Weighing Area,
It compares, judges whether unanimously with commodity picture in database respectively, if so, concluding that the commodity for being placed on Weighing Area are scanning
Commodity afterwards.
Preferably, capture commodity be placed in the photo before and after Weighing Area, respectively with commodity picture in database into
Row comparison, judge whether it is consistent specifically includes the following steps:
Photo commodity being placed in front of and after Weighing Area obscures the picture background in above-mentioned photo in addition to commodity,
Grayscale image is converted to, the average value of grayscale image all pixels is calculated, if pixel value is greater than pixel average and is denoted as 1, is denoted as on the contrary
0,1 and 0 that above-mentioned steps are generated combines in order is denoted as the fingerprint of picture；With the picture of corresponding goods in database
Fingerprint compares.
A kind of self-service cash register weight observation system, including
Barcode scanning device is used for the bar code of items scanning, forms items list, and items list counts commodity number of packages and quotient
Product weight；If commodity need to be deleted from items list, callwork personnel's assist process；
Weighing device is used at the appointed time weigh to the commodity after scanning, detects and judge commodity number of packages
Whether match with items list with commodity weight, and alarms in absence of such a match, callwork personnel processing.
Preferably, weighing device obtains weight change number and current weight, if weight change number is equal to commodity number of packages
And current weight is equal to commodity weight, then is judged as matching.
Preferably, further include
Supersonic sounding device, be used to judge weighing commodity whether be scanning after commodity,
Using the horizontal displacement direction of barcode scanning device to weighing device as positive direction, the quotient of current scanned bar code is locked
Product obtain the direction of displacement of the commodity, if the direction of displacement of the commodity falls projection in the horizontal direction and is positive, conclude weighing
Commodity be scanning after commodity.
Preferably, further include
Photographic device is used to capture the photo before and after commodity are placed on weighing device, and respectively with data
Commodity picture compares in library, judges whether unanimously, if so, concluding that the commodity for being placed on Weighing Area are the commodity after scanning.
The beneficial effects of the present invention are: by reckoning by the piece and counting weight, the commodity after avoiding commodity from not scanning or scan are replaced
The case where changing is deleted by staff's assist process commodity, is avoided deleting kinds of goods after barcode scanning demagnetization and not settled accounts demagnetization commodity band
The case where walking.
