Self-service vending machine based on sensor switches

Abstract

The invention discloses a self-service vending machine based on sensor switches, comprising a counter, a counter door, an electrical lock, a controller, a network communication module, sensor switchesand an identification module; a plurality of commodity stations are arranged in the counter; each commodity station is provided fitted with one sensor switch and allows only one commodity to be placed thereon; the front of the counter is fitted with the identification module; the controller is mounted in the counter; the electrical lock, the sensor switches and the network communication module are connected with the controller. When using the self-service vending machine, customers may open the counter door to select commodities on their own and may put unsatisfied ones back, customers may gain more visual feeling about the commodities and less uncertainty on the commodities and gain greater desire of purchase; compared with self-service vending machines based on RFID (radio frequency identification) technique, the self-service vending machine based on the sensor switches has the advantages that pasting an RFID tag to each commodity is not required, RFID tag cost can be decreased, commodities selected by customers can be recognized at a higher rate, and negative influence on mistaken payments is relieved.

Description

technical field [0001] The invention relates to an automatic vending machine, in particular to a self-selection automatic vending machine based on an induction switch.

Problems solved by technology

[0003] The first type is a vending machine with a delivery mechanism, which delivers the goods purchased by customers to the pick-up port. The disadvantage is that customers cannot identify the quality of the goods by smell or touch before purchasing, and they cannot return the goods if they find that the goods have quality problems. A single product has high requirements on the shape of the product

[0004] The second type is self-selection vending machines based on RFID radio frequency identification. The disadvantage is that radio frequency signals cannot penetrate liquids and are prone to identification errors. RFID tags need to be pasted on the products. The cost of RFID tags is relatively high, which will increase the additional cost of products.
