Display cabinet, self-service selling method and server control method

Abstract

The invention provides a display cabinet, a self-service selling method and a server control method. The display cabinet comprises a box and at least one pressure sensor, at least one elastic piece, wherein at least one placement cavity is formed inside the box; one pressure sensor is arranged inside each placement cavity; one elastic piece is arranged inside each placement cavity, one end of eachelastic piece is connected with the pressure sensor inside the same placement cavity, the other end of each elastic piece extends to the port of the corresponding placement cavity, and pressure relative to the pressure sensor is generated when stock in trade abuts against the elastic piece. According to the display cabinet, due to cooperation of the elastic pieces and the pressure sensors, changes of the length of the elastic pieces can be reflected by detecting a change value of pressure detected by the pressure sensors after goods are sold, then, the number of commodities which are taken away can be indirectly reflected, and therefore the sold commodities and the number thereof in the selling process can be known.

Description

technical field [0001] The invention relates to the technical field of vending machines, in particular to a vending cabinet, a self-service vending method and a server control method. Background technique [0002] At present, there are many new types of unmanned vending machines, which generally adopt the method of scanning electronic tags, attaching RFID electronic tags to each commodity, installing readers and antennas in the containers, and reading the tags in the containers through readers. , to obtain the goods in the container before and after closing the door, and then confirm the goods taken out by the user, but the cost of electronic tags is too high at present, and this method is still not popular. Therefore, how to design a new structure and method for determining the type and quantity of sold commodities has become an urgent problem to be solved. [0003] In addition, there is a lack of monitoring measures during the vending process of vending machines. If the g...

[0003] In addition, there is a lack of monitoring measures during the vending process of the vending machine. If the goods in the container are damaged, there is no way to check; at the same time, some vending machines are easy to get stuck in the outlet when the goods are shipped, and it is difficult to take them out
