The present application will be further described in detail below with reference to the accompanying drawings and embodiments in order to better clarify the object, technical scheme and advantages of the present application. However, it is to be understood that the specific embodiments described herein are merely exemplary of the present application and are not intended to limit the present application. The item verification or checking method provided in the present application may be applied in the application environment for self-service settlement of goods for example, such as in an unmanned supermarket, as illustrated in FIG 1. In such an environment, the cash register controller comprises a processing unit and a storage unit. The processing unit is mainly responsible for analyzing weight information, image sensing data and RFID (Radio Frequency Identification) information of relevant goods, and processing internal pre-stored goods information and goods settlement, etc. The storage unit is mainly configured to match the European Article Number (EAN code) and the two-dimensional code corresponding to each different product, with the corresponding product weight, product name, transaction record, image sensing data, and stored product information (such as price, weight, date of manufacture, RFID information, shelf life, etc.). The sensing coverage of the image sensor includes text information on the product package, such as the product name. The RFID reader reads the RFID tag information on the product, and to the product surface or the product package is attached the RFID tag written with an EPC (Electronic Product Code) code according to the corresponding rules, and the EAN (European Article Number) code can be parsed by scanning the EPC code. The weighing sensor is configured to sense and provide the product weight data to the cash register controller, so as to determine the total weight of the current goods or a plurality of goods. The scale pan is used for holding goods, and may be made of plastic materials, or materials which do not attenuate RFID signals. The scale bracket connects the scale pan and the sensor and acts as a conductive structural member. The displayer, such as a touch displayer or screen, displays the goods settlement status and process, product identification, traceability information, etc., by connecting to the cash register controller.
In one embodiment, as illustrated in FIG 2, there is provided an item checking method, which is illustrated as applied to the cash register controller in FIG 1 as an example, and includes the following steps:
Step 202: Recognizing an RF label of the item to be checked, and obtaining an EPC code of the item to be checked.
EPC code is a new generation product coding system introduced by EAN.UCC. The EPC code assigns a globally unique code to each single product, and the EPC code adopts a 96-bit (binary) encoding scheme. The 96-bit EPC code can be assigned to 268 million companies. Each company can have 16 million product categories, each with 68 billion independent product codes. An RF label is the physical carrier of the EPC code, and attached to traceable items that can be circulated globally and identified, read and written. Items to be checked can be goods or books, etc., selected and purchased by users in a self-service unmanned freezer, self-service unmanned supermarket, self-service bookstore or self-service library, etc.
Step 204: Obtaining the RF recognition information of the item to be checked according to the EPC code. RFID is a wireless communication technology which identifies specific targets and reads and writes relevant data through radio signal, without establishing mechanical or optical contact between the identification system and a particular target. The radio signal transmits data from the tag attached to the item by an electromagnetic field that is modulated into a radio frequency to automatically identify and track the item. The tag includes electronically stored information which can be identified within meters of the tag. The RF label does not need to be within the line of sight of the reader, and can be embedded within the object being tracked. The RF recognition information of the item to be checked includes item type, item name, item weight, weight tolerance, date of manufacture, shelf life, QR code, price, etc.
Specifically, the EPC code is a single product unique code, the item QR code is a single product unique code, and the EAN code is a single product category unified code, that is, one item type corresponds to one EAN code, and one EAN code includes N EPC codes and QR codes under the same item type. The built- in storage pre-stores N EAN codes according to the item type, and each EAN code includes the item type, item name, item weight, weight tolerance, date of manufacture, shelf life, QR code, price, etc.
Step 206: Acquiring physical information of the item to be checked.
Physical information refers to the information on the inherent properties of an item, such as the weight, size, shape, color, etc. of the item. Specifically, the physical information includes the weight information and the image information.
For example, the weight of an item can be acquired via the weighing sensor, and the image of item can be acquired via the image sensor. Step 208: When the physical information of the item to be checked matches with the RF recognition information of the item to be checked, outputting the RF recognition information as the item checking information of the item to be checked. The item checking information refers to the item information after checking, such as item type, item name, item weight, weight tolerance, date of manufacture, shelf life, QR code, price, etc. Match the physical information of the item to be checked with the RF recognition information of the item to be checked, for example, matching the weight acquired via the weighing sensor with the weight in the RF recognition information, when the physical information of the item to be checked matches with the RF recognition information of the item to be checked, it indicates the RF recognition information acquired by the RF tag is accurate, and then the RF recognition information is output as the item checking information of the item to be checked.
The above item checking method includes recognizing the RF label of the item to be checked, and obtaining the EPC code of the item to be checked, obtaining the RF recognition information of the item to be checked according to the EPC code; acquiring the physical information of the item to be checked, and, when the physical information of the item to be checked matches with the RF recognition information of the item to be checked, outputting the RF recognition information as the item checking information of the item to be checked. By first acquiring the RF recognition information of the item to be checked via the RF label and then acquiring the physical information of the item to be checked, and verifying the acquired RF recognition information of the item to be checked via the physical information of the item to be checked, and outputting the RF recognition information as the item checking information of the item to be checked when the physical information of the item to be checked matches with the RF recognition information of the item to be checked, it can improve the accuracy in recognizing the item information of the item to be checked and solves the problem of omission and erroneous judgment of items.
In one embodiment, as illustrated in FIG 3, after acquiring the physical information of the item to be checked, the method further includes: Step 304: When the physical information of the item to be checked mismatches with the RF recognition information of the item to be checked, acquiring overlapping information between the physical information of the item to be checked and the RF recognition information of the item to be checked; and Step 306, outputting the item checking information of the item to be checked, according to the physical information of the item to be checked and the overlapping information. When the physical information of the item to be checked mismatches with the RF recognition information of the item to be checked (for example, the items to be checked actually include A, B, C and D, the RF recognition information of items to be checked includes A, B and C, and the acquired physical information of items to be checked includes A, B, C and D), then, acquiring the overlapping information between the physical information of the item to be checked and the RF recognition information of the item to be checked, and the overlapping information includes A, B and C, the overlapping information is then superimposed with the item information removing the overlapping information, outputting the item checking information of the item to be checked.
In one embodiment, as illustrated in FIG 4, acquiring the physical information of the item to be checked, includes: Step 404: acquiring the weight information; when the physical information of the item to be checked matches with the RF recognition information of the item to be checked, outputting the RF recognition information as the item checking item to be checked, which includes: Step 406: acquiring the weight tolerance information in the RF recognition information of the item to be checked; and Step 408: when the weight of the item to be checked is within the scope of weight corresponding to the weight tolerance information, outputting the RF recognition information as the item checking information of the item to be checked. In practice, the weight information of the item can be acquired via the weighing sensor. For example, items to be checked actually include A (50g), B (100g) and C (200g), the acquired weight tolerance information in the RF recognition information of the items to be checked includes (weight tolerance: 50g ± 1 g), (weight tolerance: 100g ± 2g) and (weight tolerance: 200g ± 5g), and the acquired weight information of the items to be checked includes the gross weight 348g and the respective weight of 50g, 100g and 198g. At this point, the acquired weight information of the item to be checked matches with the weight tolerance information in the RF recognition information of the item to be checked, as such, outputting the RF recognition information as the item checking information of the item to be checked.

For example, the RF recognition information of items to be checked includes A (50g, RMB5), B (1 OOg, RMB10) and C (200g, RMB15), and the physical information of the items to be checked includes the total weight 348g and the respective weight of 50 g, 100g and 198g, and the physical information of the items to be checked matches with the RF recognition information of the item to be checked, and the acquired paid items information includes that A has been paid, then removing A from the RF recognition information, and outputting the RF recognition information after removal of A as the item checking information of the items to be checked, that is, the item checking information of the items to be checked includes B (1 OOg, RMB10) and C (200g and RMB15). This can effectively distinguish the items settled and the items to be settled. Specifically, obtaining the paid items information, according to the EPC code of the item to be checked and the payment information, includes: acquiring the item identifier in the payment information; and, matching the item identifier in the payment information with the EPC code of the item to be checked, and treating the matched item identifier as the item identifier in the paid items information. For example, the item identifier in the payment information is A, and match it with the EPC code of the item to be checked, if they match with each other, this indicates that A is one of the items to be checked and A has been paid.

In the system above, the weighing sensor, scale pan, scale bracket and displayer connect to the cash register controller, and when users take out corresponding goods from the counter or freezer and place them on the scale pan of the checkout counter, the weighing sensor identifies the product weight and transmits the recognized weight information via A/D conversion (analog to digital signal) to the cash register controller, and the cash register controller will analyze and make determination on the received information, match the received weight information with goods of the same weight prestored in the storage unit, and maintain the current state of standby for storage.
The recognized weight information, EPC code information, and product name information from image sensing, will then be transmitted to the cash register controller. Step 1 : The cash register controller first recognizes the EPC code and obtains the corresponding match relationship by extracting the EAN code from built-in storage, and determines the weight matching degree of goods based on the single product weight tolerance, according to the product weight of the product EPC code in the weight information. Step 2: The cash register controller identifies the text information on the product package based on the OCR technology via the camera, and extracts the product name information therein, and synchronously retrieves the product name in the storage unit based on the EAN code corresponding to the EPC code parsed by the RFID in Step 1 , so as to compare and determine the corresponding match relationship between the product name, weight, EPC code and the corresponding product EAN code in the built-in storage. Step 3: The cash register controller determines whether all goods information are matched according to the conditions above, determines whether the current goods can be settled, and identifies and categorizes goods that have been paid, and gives real-time feedback of the above recognized information to users or consumers, so as to realize the settlement by RFID through the cashier system.
Wherein, the EPC code is a single product unique code, the product OR code is a single product unique code, and the EAN code is a single product category unified code, that is, one product type has one EAN code, and one EAN code includes N EPC codes and OR codes under the same product type. The built-in storage prestores N EAN codes according to the product type, and each EAN code includes the product type, product name, product weight, weight tolerance, date of manufacture, shelf life, OR code, price, etc. The accounting process and principle before actual settlement are as follows: S1 : placing the goods on the scale pan, and identifying the EPC code of a single product (such as 0001 , 0002, 0003) via RFID, and parsing the EAN code through recognizing the EPC code, and retrieving the corresponding matched EAN code in built-in storage, and retrieving the product type, product name, product weight, weight tolerance, date of manufacture, shelf life, OR code, price and other information contained in an EAN code. S2: the controller determines whether the current total weight of the goods or a plurality of goods is within the tolerance scope, according to the total weight of goods above measured via the weighing sensor based on the EPC code (such as 0001 , 0002, 0003), and the weight tolerance of goods based on the EPC code (such as 500g±10g for a single product). S3: the controller identifies the text information on the goods package via the camera, and extracts the product name (such as fine cut beef briskets) from recognizing the text information of goods; based on the successful match in S2, conduct information matching, and when the information matching succeeds, the extracted product name of goods is“fine cut beef briskets”. S4: the controller recognizes and acquires all product names via the camera, and based on the successful match in S2 and S3, further retrieves the product name included in the EAN code for matching. S5: based on the successful match of the above RFID recognition, weight recognition and camera recognition, the controller categorizes the settled and unsettled flag bits according to the EPC code, so as to avoid repeated settlement of RFID goods at the settlement.
The cash register controller can comprise a video output interface, a keyboard input, a cash box, a network interface, etc., and the image sensor can specifically include infrared sensing, face recognition, human behavior recognition, product distance and product size identification, and the like. The above system, which can be directly used in an RFID unmanned supermarket, unmanned freezer and other scenes, and realize the pre-settlement item recognition and error correction functions by a plurality of technical means such as product name confirmation in combination with weight and image sensing, and RFID recognition, and strongly secure the accuracy in product settlement, effectively solve problems such as expired goods, mismatched weight and mismatched label price, and constitute an effective guarantee for RFID smart unmanned shopping based on that RFID recognition can accurately recognize the product type and quantity, is one of the necessary measures to push forward the smart shopping.
