Electronic scale and working method thereof

Abstract

The invention discloses an electronic scale and a working method thereof. The electronic scale is used for weighing the articles with RFID tags through RFID (radio frequency identification devices) technology. The electronic scale comprises a main controller (1), an input module (2), a weighing module (3) and an RFID module (4). According to the situation that the RFID module (4) has read-only and read-write functions, the electronic scale can finish two charging modes of weighing in an online or an offline manner so that a settlement system can finish settlement quickly. The RFID electronic scale of the invention can simultaneously process a large amount of data information because the data transmitting rate of the RFID module (4) is quick; a settlement counter does not need to scan the tag of each article one by one; by using a non-contact mode, the reader-writer can quickly identify the article information in the RFID tag; so the speed of the follow-up settlement is greatly improved.

Description

technical field [0001] The invention relates to an electronic scale and its working method, in particular to an electronic scale with RFID (Radio Frequency Identification) function, which is used in restaurants, supermarkets, food stores and other places, and can weigh items without fixed weight and with RFID tags. Heavy electronic scales and how they work. Background technique [0002] The infiltration of electronic technology in the mid-1950s promoted the development of weighing tools. Since the appearance of electromechanical integrated electronic scales in the early 1960s, after more than 40 years of continuous improvement and perfection, electronic scales have developed from the initial electromechanical integrated type to the current fully electronic and digital intelligent type. There are mainly two types of electronic scales currently used commercially. One is an electronic scale used in small retail stores; the other is a barcode label suitable for use in medium-s...

Problems solved by technology

[0014] 1) Complicated settlement: Although the price information and / or code information and / or barcode information are marked on the item, it is still necessary to manually enter the information one by one or enter the information one by one through a barcode scanner during settlement, which is slow;

[0015] 2) Complicated operation: it takes a relatively long time for the whole process to print the price label, output the label and paste it on the item. In environments such as restaurants or supermarkets with a relatively heavy workload, the complex operation of this system is very obvious The low efficiency of the work has been brought about by the area, such as a large number of customers waiting in line for settlement;

[0016] 3) High cost: Because each item needs to print a price tag, the printing module is added, and the price tag cannot form a closed-loop recycling, thus increasing the cost
