Commodity weight-based self-service shopping system and control method thereof

Abstract

The invention discloses a commodity weight-based self-service shopping system, which comprises a first weight acquisition device and a first communication device, wherein the first weight acquisitiondevice is used for acquiring the weight change value of a commodity in a shopping device, the weight change value comprises a weight increase value, and the first communication device is used for sending the weight change value to a server; a client comprises a shopping information acquisition device and a second communication device, the shopping information acquisition device is used for acquiring the shopping information, the shopping information comprises the identity information of a target commodity, and a second communication device is used for sending the shopping information to the server; and a binding device is used for building a binding relationship between the shopping device and the client. Thus, the commodity purchased by a client can be accurately recognized through the weight of the commodity, correct payment in the case of settlement of the client is further ensured, the commodity is recognized through the weight, the hardware cost is low, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a self-service shopping system based on commodity weight and a control method thereof. Background technique [0002] Traditional supermarkets generally have the problems of long queues for checkout and high labor costs for hiring cashiers.
