A self-service weight reduction weighing charging system and a self-service weight reduction weighing charging method

Abstract

The present invention brings forward a self-service weight reduction weighing charging system and a self-service weight reduction weighing charging method. The system comprises a weight reduction weighing and stockout alarm unit and an information processing and transmission unit, both of which are communicatively connected. The weight reduction weighing and stockout alarm unit automatically calculates the weight information of the goods sold by a weight reduction weighing method, and transmits the weight information of the goods sold to the information processing and transmission unit after determining the weight information to be valid. The information processing and transmission unit conducts automatic calculating based on the weight information to obtain the price information of the goods sold. The system of the invention is highly systematic, integrated and intelligent. The weight information of the goods sold is detected in real time and generated based on the weight reduction weighing and stockout alarm unit. The price information of the goods sold is generated in real time based on the information processing and transmission unit. The two units are dynamically combined to work highly intelligently. When charging ends, intelligent stockout judging is performed. The weight reference updating is conducted after replenishment, and whether weight reduction is effective is scientifically determined. The system and method of the invention have a more broad application prospect.

Description

technical field [0001] The invention relates to a decrement weighing technology, in particular to a self-service decrement weighing and billing system and a self-service decrement weighing and billing method. Background technique [0002] Self-service consumption has become a trend, and more and more people like to conduct various types of consumption through self-service. The existing canteen catering sales system includes a POS machine with keyboard input and a POS bookkeeping management server, which mainly realizes the functions of electronic deduction and recording consumption amount. Its usage process is as follows: the user selects the type and number of servings (or number) of meals that the user needs, and the salesman manually calculates the total amount of fees payable according to the type and quantity, and enters the amount on the small keyboard of the POS machine, and the user After swiping the card on the rice-selling POS machine, the automatic fee deduction ...

AI Technical Summary

Problems solved by technology

[0003]The main defects of the system are as follows: First, the system cannot obtain detailed consumption data such as the variety and quantity of meals

Since the system only records the consumption information of the total deducted fees, but does not have information on the types and quantities of meals sold, it is unable to provide detailed data on the types and quantities of sales, and cannot conduct relevant data analysis

Second, the system cannot provide a sales method that matches the price and volume

In the traditional hand-cooked rice mode, the amount of a meal depends entirely on manual experience. There are differences in the amount of each meal, but the price is the same. Consumers have opinions on this

Third, the system cannot solve the problem of coexistence of insufficient food and waste

Since the food is sold by portion or by each individual, and everyone’s appetite is different, some people can’t finish the whole portion, and some people can’t eat enough. It can’t meet the actual needs of consumers, and it is easy to cause waste.
