Specifically, in response to the customer 2 scanning the code and authorizing the merchant to use his payment account for the transaction (e.g., authorizing the merchant to use his payment account for privacy-free payment), the cabinet door 104 is opened (the lock on the cabinet door 104 is released); before the vending machine 1 opens the cabinet door 104, the tag counting module counts the commodities on each shelf 102 of the vending machine 1 by scanning and counting the RFID tags by using the RFID reader 110, and stores the counting result (first-time tag counting information) in the memory 108 a; after the cabinet door 104 is opened, a user can take the commodity at will, and the cabinet door 104 is closed after the taking is finished; in response to the closing of the cabinet door 104, the tag counting module 202 counts the commodities in the cabinet 100 by using the RFID reader 110, and since part of the commodities are taken away, compared with the first counting, the tag information of the taken commodities will not appear in the counting result (second tag counting information) of the second counting, and then the first tag counting information and the second tag counting information can be compared to determine the types and the number of the commodities taken by the customer 2.
c) and the settlement module 206, the settlement module 206 can calculate the amount of the goods according to the finally determined type and quantity of the commodities taken by the customer 2, send the amount of the goods to the server side 3, and deduct corresponding money from the payment account authorized by the customer 2.
Through the above manner, the vending machine 1 provided by the embodiment can rapidly determine the types and the number of commodities taken by the customer 2 by means of statistics of the RFID tags in the cabinet body 100, does not need the customer 2 to pay extra labor for settlement, simplifies the shopping process of the customer 2, improves the user experience, and realizes' scanning to open a door, namely taking the goods away; in addition, the arrangement of the goods in the cabinet 100 of the vending machine 1 is not limited, and the goods stored in the cabinet can be greatly enriched without using the shelf 102 in a fixed form.
In addition, in order to more easily detect the theft state of the opened and used commodity and reduce the possibility that the money cannot be recovered, the vending machine 1 according to the present embodiment is subjected to a plurality of innovations of hardware and software.
Specifically, in the vending machine 1 provided in this embodiment, each shelf 102 is provided with a weight sensor 116 to weigh the weight of the commodities stored on the shelf 102, and each weight sensor 116 is electrically connected to the main control system 108, so that the weight data of the commodities on each shelf 102 can be fed back to the main control system 108 for processing. In terms of software, the processor-readable instructions stored in the memory 108a of the vending machine 1 also include a weight statistics module 204 capable of collecting weight data obtained by each weight sensor 116 and determining the amount of the payment based on changes in the weight data.
In some embodiments, the shelf 102 of the vending machine 1 may be formed as an integral structure, and the weight sensor 116 may weigh the total weight of the products in the cabinet 100. In some scenes, the goods are clamped between the upper and lower shelves 102, so that the force borne by the weight sensor 116 of the lower shelf 102 is increased, the measurement error of the weight of the goods on the layer is caused, and the weighing of the total weight can prevent the influence of the situation on the total weight statistics; in addition, adopt and weigh the mode to whole, the cooperation RFID reads the ware 110 and scans the mode of statistics to the whole commodity that carries out of cabinet body 100, and the commodity can all be put at will, take at will when getting goods in the cabinet body 100, has effectively improved user experience.
Referring to fig. 3, at a first moment when the cabinet door 104 of the vending machine 1 is in a locked state, a first statistical step S01 is performed to obtain first weight data and first label statistical information of the articles in the cabinet 100. In the present embodiment, the first weight data is the total weight of the commodities in the cabinet 100; in another embodiment of the present invention, the first weight data may be weight data obtained by weighing each commodity on each shelf 102 in the cabinet 100. The first tag statistical information is a tag information list obtained by summarizing and counting the RFID tags of all the articles in the cabinet 100.
after the first counting step of S01 is completed, the vending machine 1 enters a standby state. The vending machine 1 in the standby state can keep the communication port 108c connected to the server side 3 open, and prepare to acquire authentication information indicating that the customer 2 has completed the payment account authorization from the server side 3.
When the customer 2 scans the two-dimensional code 114 on the body of the vending machine 1 (or, in other embodiments, the camera of the vending machine 1 scans the payment two-dimensional code of the customer 2) and completes authorization of the payment account for the transaction, the server 3 sends authorization verification information indicating that the customer 2 has completed authorization of the payment account to the vending machine 1; in response to receiving the authorization verification message, the electronic lock 106 is unlocked from the cabinet door 104.
after the door 104 is unlocked, the customer 2 can open the door 104, take the goods in the cabinet 100 at will, and close the door 104.
This embodiment can cope with two scenarios: in the first scenario, customer 2 takes the merchandise normally; in the second scenario, customer 2 unpacks the package of goods and, after use, replaces the package with the RFID tag. The following describes the payment settlement method of the vending machine 1 according to the present invention with reference to these two scenes.
In response to the closing of the cabinet door 104, the second statistical step S02 is performed: second weight data and second label statistical information for the items within the cabinet 104 are obtained. And acquiring the second weight data and the second label statistical information in a manner corresponding to the first weight data and the first label statistical information.
in the present embodiment, if the first weight data obtained in the first statistical step of S01 is the total weight of all the commodities in the cabinet 104, the second weight data obtained in the second statistical step of S02 is the total weight of all the commodities in the cabinet 104.
after the second counting step of S02 is completed, the tag-based deposit determination step of S03 is performed: and determining the amount of the goods money based on the first label statistical information and the second label statistical information.
Specifically, the first tag statistical information is compared with the second tag statistical information, because the first tag statistical information indicates the tag statistical information in the cabinet body 104 before the customer 2 takes the commodity; after second label statistical information instructs customer 2 to take the commodity, the interior label statistical information of cabinet 104, consequently, to first kind of scene, through comparing first label statistical information and second label statistical information, confirm the statistical conditions of the interior label of cabinet 104, can confirm the amount of the money of goods that corresponds with the label that reduces according to the reduction condition of label. And for the second scene, simply comparing the first label statistical information with the second label statistical information to obtain a result that the label is unchanged.
in order to effectively prevent such a phenomenon, in the payment settlement method of the vending machine 1 according to the present embodiment, if the label is unchanged, the process proceeds to a payment determination step based on the weight of S04: based on the first weight data and the second weight data, an amount of the payment is determined.
In the second scenario, in the step of determining the amount of goods based on the label in S03, it is not possible to determine whether or not the behavior of customer 2 for taking the goods has occurred since no change in the label is obtained, and it is further not possible to settle the account for the behavior of customer 2 for taking the goods.
by comparing the first weight data and the second weight data, the change situation of the weight of the commodity in the cabinet body 104 before and after the transaction action of the customer 2 can be judged, and the change of the weight can be effectively utilized to identify the second scene of returning the package of the consumable product which can be disassembled for use. In this embodiment, the amount of the payment of the goods can be directly determined according to the amount of change of the weight, and the corresponding money is deducted from the authorized payment account in advance, so that the situation that the payment of the goods cannot flow back is prevented. In this embodiment, the first weight data and the second weight data respectively correspond to the total weight of the commodities in the cabinet 100 before and after the transaction of the customer 2, and the weight value obtained by subtracting the weight value of the second weight data from the weight value of the first weight data is the weight reduction amount of the commodities in the cabinet.
In some embodiments, the use of weight sensor 116 and RFID reader 110 in combination may identify and monitor the access of customer 2 to the merchandise during the opening of cabinet door 104. For example, the weight sensor 116 may record the change of the weight of the goods inside the cabinet 100 with time during the opening process, determine whether or not the goods are taken off the shelf 102 based on the change of the weight of the goods on the shelf 102 in the steady state, or determine the type and number of the goods taken by the customer 2 by using the value of the weight change in combination with any suitable information such as the pre-stored weight information of the goods and the placement state of the goods on the shelf 102. If part of the goods are put back, whether the goods are put back or replaced after being used can be judged according to the weight-time change relation in the taking process of the customer 2. For example, during the picking process, the vending machine 1 detects that the weight of a certain shelf 102 is reduced by 500g by using the weight sensor 116, and determines that the customer 2 has picked up an article a based on the weight-article correspondence and/or the shelf placement status information. Then, the vending machine 1 monitors that the weight of the commodity is increased, but the weight increase is less than the weight reduction amount (500g) in the taking process, and in the comparison process of the RFID tag statistical information, the number of the RFID tags is not reduced, so that the payment of the commodity payment can be received according to the commodity type judged based on the weight reduction amount, namely the unit price of the commodity a is received.
in the embodiment in which the behavior of the customer 2 taking the product is recognized and monitored by the weight sensor, the first weight data and the second weight data may record the total weight of the product placed on each shelf 102. Based on the weight data of the commodities on each shelf, the type and the number of the commodities on each shelf can be distinguished by monitoring the weight change of the local shelf during replenishment, and when a customer takes the commodities, the possible range of the types and the number of the commodities can be further reduced, the types and the number of the commodities taken by the user can be more easily judged, and the identification accuracy is improved. In some embodiments, the placement position of the goods can be limited to improve the accuracy of the identification of the goods taken.
in other embodiments, the amount of the good may also be determined based on the highest price per weight (price/weight) in the good. Specifically, the weight-based payment determining step of S04 further includes: determining the highest price per unit weight in the commodity, and storing the highest price per unit weight as the highest price or storing the highest price in advance; then, determining the weight reduction amount of the commodities in the cabinet according to the first weight data and the second weight data; and determining the amount of the goods according to the product of the weight reduction amount and the highest unit price. For example, a plurality of vending machines 1 may be used to sell products in a larger scale, and each vending machine 1 sells products with a price close to or the same price per unit weight, such as water, beverage, etc., while one vending machine 1 sells products with a lower price per unit weight, and another vending machine 1 sells products with a higher price per unit weight, such as puffed food, sundries, etc.; in the second scenario, if the customer 2 returns the package of the goods after using the goods, the customer can pre-deduct the amount of the goods by multiplying the weight reduction amount by the highest price per unit weight of the goods sold in the vending machine 1, and further prevent the goods from being irretrievable by deducting or transferring the money enough to repay the goods, thereby reducing the security risk of the merchant.
In addition, considering that a slight weight change may occur during the taking and placing process due to an error of a weight sensor or condensed water outside a beverage bottle sold in a vending machine such as a refrigerator, in this case, the weight reduction should not be regarded as a case where a commodity is taken, and therefore, in the present embodiment, preferably, the step of determining the amount of the payment according to the product of the weight reduction and the highest unit price further includes: comparing the weight reduction amount with a preset threshold value, and directly determining the amount of the goods money as 0 when the weight reduction amount is lower than the threshold value; when the weight reduction amount is higher than the threshold value, a multiplication operation with the highest unit price is performed, and the amount of the money is determined according to the product of the weight reduction amount and the highest unit price. The weight reduction amount determination mode with the threshold value can reduce the occurrence of mistaken deduction.
After the determination of the amount of the goods money is completed, if the amount of the goods money is larger than 0, the settlement information containing the amount of the goods money is sent to the server terminal 3 for settlement, and the money corresponding to the amount of the goods money is deducted or transferred from the payment account authorized to be deducted by the customer 2, so that the settlement is completed.
After the settlement is completed, the vending machine 1 reenters the standby mode. In some embodiments, the weight data and the tag statistical information of the current articles in the cabinet 100 may be updated by using the second weight data and the second tag statistical information obtained in the second statistical step of S02, and used as a comparison criterion when the articles taken by the customer 2 who uses the vending machine 1 are judged (i.e., assigned as the first weight data and the first tag statistical information in the newly initiated payment settlement process).
in some embodiments, the settlement information further includes information as to whether the amount of the payment is determined by comparing the RFID tag statistics back and forth or by comparing the weight data back and forth, to improve traceability of the payment settlement method.
in order to respond to a detected theft condition in real time, the vending machine 1 of the present embodiment further includes an alarm device 118 communicatively coupled to the host system 108. In some embodiments, the balance of the customer's payment account is obtained upon authentication of the customer, and when the balance in the customer's payment account is insufficient, the host control system 108 will send an alarm instruction to the alarm device 118 to alarm. By inquiring the account balance in advance, the alarm can be given in advance when the balance in the payment account is insufficient, and the problem that the payment can not flow back is prevented. In other embodiments, if the cabinet door is opened for too long a time period exceeding a preset time threshold, which may be any value between 30 and 200 seconds, preferably any value between 30 and 60 seconds, an alarm command may be sent to the alarm device 118 to prevent theft. With the prerequisite of cabinet door open time as the warning, can prevent on the one hand that some customers from dodging the settlement flow through opening the cabinet door, on the other hand can be in some automatic vending machines that combine the freezer to use, prevent to open behind the cabinet door vapor in the outside gas inside too much condensation, and cause the inaccurate condition of weight sensor measuring.
It should be noted that, although the reader is described as the RFID reader 110 in this embodiment, in other embodiments of the present invention, the reader may be a camera or any other suitable input device, for example, image recognition may be performed based on a graphic feature on the surface of the product, as long as it can complete the determination of the position of the product.
Through the mode, the vending machine 1 provided by the embodiment can effectively detect that a customer opens the package for use after taking the commodity, and can return the package with the RFID tag to the scene, intelligently distinguish the scene from the scene in which the customer normally uses, and take user experience and the safety risk of a merchant into consideration.
In some embodiments, the RFID tag carried by an article can also indicate weight information of the article corresponding to the RFID tag. Through using the label that has weight information, can utilize RFID to read ware 110 and read the weight information of commodity, and then can compare actual weight data with the weight data that obtains according to the weight information sum in the label, and carry out weight judgement, can improve the commonality of automatic vending machine on the one hand, make it can be applicable to the commodity of some interim packings, if according to the fresh product that the unit price was sold, on the other hand can make things convenient for the merchant to carry out the renewal to the price.
