Fruit and vegetable accumulated-weighing valuation method and electronic scale

Abstract

The invention discloses a fruit and vegetable accumulated-weighing valuation method and an electronic scale, and belongs to the metering field. The method comprises that the total weight is obtained; a present commodity is selected; an incremental method is used to calculate the weight of the present commodity and inquire the unit price of the present commodity, and the sum and total sum of the present commodity are obtained; and information and total sum of the present commodity are back fed. In the weighing process, commodities are placed in packaging bags on the scale successively instead of being weighed independently, it is characterized that weighed commodities are not removed from the scale, a step of removing the weighed commodities from the scale in the weighing process is avoided, a process of bagging commodities after collection is also avoided, the working efficiency of salesclerks is improved substantially, and the condition of long queuing in fruit and vegetable collection channel is alleviated greatly. The electronic scale comprises a sensing module, a keyboard module, a calculation module, a feedback module and a weighing frame, and the weighing frame is provided two cross bars for hanging the packaging bags.

Description

technical field [0001] The invention belongs to the field of metering, and relates to a novel accumulative weighing and pricing method and an electronic scale, in particular to an electronic scale used in fruit and vegetable stores and chain stores thereof. Background technique [0002] There are two processes for salespersons in fruit shops and vegetable shops to collect money: (1) Weigh and price the products purchased by customers individually, and finally sum up the total consumption amount. Obviously, each product has a process of weighing up and down; (2) Bag the goods purchased by customers and then hand them over to customers, which is called the bagging process. [0003] If a new type of scale can be manufactured, it is not necessary to take off the weighed goods from the scale, but only need to put the goods on the scale in turn, then there is only one process of weighing all the goods, and the process of weighing and pricing will be obvious. Speed ​​up; in additi...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a method of accumulative weighing and pricing of fruits and vegetables and an electronic scale using the method to solve the problem of inefficiency caused by separate weighing and bagging of each commodity in the existing accumulative weighing and pricing. The time for the salesperson to weigh and calculate the price has greatly eased the situation of long queues at the fruit and vegetable collection channel for payment
