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

Embodiment 1

[0052] RFID electronic scale of the present invention comprises the following parts:

[0053] Main controller 1: The core part of the RFID electronic scale, which controls all other modules and is responsible for the information transfer between related modules.

[0054] Input module 2: The operator can input required information into the RFID electronic scale through the input module 2, such as food unit price, name, code, etc., and the main controller 1 can query the unit price of the food according to the food name and / or code information input by the input module , and calculate the total price. The input module 2 is buttons marked with names of various foods or buttons marked with pictures of foods, and can also be a keyboard or a touch screen. In this embodiment, the input module 2 is a waterproof membrane key, and after pressing the key, the unit price or name or code information that can represent the food is input to the main controller 1 .

[0055] Weighing module ...

Embodiment 2

[0082] Compared with the electronic scale in Embodiment 1, the RFID electronic scale has the same main controller 1, input module 2, weighing module 3, communication interface 5, display module 6, sound and light prompt module 7, memory expansion interface 8, The difference is that the RFID module 4 is different. In Embodiment 2, this module is an RFID read-write module, which can read the information in the RFID tag, and can write relevant information into the RFID tag, such as transaction information. The information includes at least price information, information such as food weight, food name or code, and can also be included in transaction information to provide more useful information for the settlement system.

[0083] The working steps of the RFID electronic scale with this structure are as follows:

[0084] 1) Place the tableware with the RFID tag on the weighing module 3 after being filled with food;

[0085] 2) The weighing module 3 weighs the food, and transmits ...

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...
