Vending machine, vending method and vending system thereof

Abstract

The invention discloses a vending machine, a vending method and a vending system thereof. The vending machine comprises a machine body, a door body, at least one layer of shelf and a weighing device installed inside the machine body; the vending method comprises following steps: collecting the weight of the goods on the shelf before and after the sale; calculating the difference between the weightof the goods on the shelf before the sale and the weight of the goods on the shelf after the sale; if the change difference is less than a first weight change threshold, an alarm prompt is given out,wherein the first weight change threshold is less than or equal to zero. The invention does not rely on the RFID tag and timely judges the misplacement and the replacement of the goods, thereby ensuring the interests of the merchant and the user.

Description

technical field [0001] The invention belongs to the technical field of intelligent equipment, and in particular relates to a vending method of an unmanned vending equipment, an unmanned vending equipment and an unmanned vending system. Background technique [0002] The current unmanned vending machines need to attach RFID (Radio Frequency Identification, radio frequency identification) electronic tags to each product, and use the method of scanning electronic tags to identify the goods. Although this method is simple and convenient to operate, the cost of electronic tags is too high , this method is still not universal. [0003] In some related technologies, the price is calculated by installing weight sensors on the shelves to detect the difference in weight of the goods on the shelves before and after the customer picks up the goods, but there are still some problems in this method: if the customer purchases, the A-layer partition If the goods are intentionally or uninten...

Problems solved by technology

[0002] The current unmanned vending machines need to attach RFID (Radio Frequency Identification, radio frequency identification) electronic tags to each product, and use the method of scanning electronic tags to identify the goods. Although this method is simple and convenient to operate, the cost of electronic tags is too high , this method is still not popular

[0003] In some related technologies, the price is calculated by installing weight sensors on the shelves to detect the difference in weight of the goods on the shelves before and after the customer picks up the goods, but there are still some problems in this method: if the customer purchases, the A-layer partition If the goods are intentionally or unintentionally placed in the area of ​​goods with different prices on the B-layer partition, the system will have errors in pricing, and the system will not be able to judge and discover this problem in time

Furthermore, if the goods continue to stay on the wrong shelf, it will cause pricing errors for other customers who shop later, and the entire system will experience price disorder. It will affect the user experience and even cause user complaints

[0004] In other related technologies, infrared emitters and infrared receivers are respectively installed on the upper and lower sides of the shelf, and the presence or absence of the current shelf item is judged by infrared sensing, but it is impossible to judge whether the item is replaced from position A to position B; at the same time, the method Use RFID electronic tags to affix each product to further judge whether the items have been replaced, but the cost of RFID tags is too high, so this method cannot be widely used at present
