Electronic scale control method

Abstract

The invention relates to a control method of an electronic scale, which is implemented according to the following steps: customers place a product to be weighed onto a scale pan; signal wires that are connected with four sensors on four corners under the scale pan centralize analog weighing signals that are measured and transmit the signals to an A / D module; the A / D module converts the analog signals into digital signals, and a mainboard computes and processes the weights, and further sends the weights onto a main display and a customer display; the mainboard prints a price tag of the weighted product through an LPT communication interface after receiving a command that is sent out; an operator uses a scanner that is externally connected by a USB / RS232 port to scan barcodes of unpaid products one by one; data is transmitted to the mainboard through the signal wires; the mainboard computes and processes the data through foreground software, and further sends the data onto the main display and the customer display; when summing and bill settling are required, the operator can operate through a touch screen or a keyboard that is externally connected with a PS / 2 port; the data stored in a hard disk is called by foreground processing, and the required data is printed through the LPT communication interface.

Description

technical field [0001] The invention relates to an electronic balance, in particular to a method for controlling the electronic balance. Background technique [0002] An electronic scale is an electronic scale that integrates weighing, printing, and POS systems. It is mainly used in supermarkets and hypermarkets; customers put the items to be weighed on the weighing pan of the electronic scale, and the scale prints out the corresponding price tags or receipts; and supermarkets or stores can use the POS system to use scanners to read Take labels and barcodes and utilize other specialized equipment to record revenue at that point of sale. [0003] In some large stores or supermarkets, the use of electronic scales is usually to set up several electronic scales at the optional racks of different types of goods, and after the scales are printed, they will be collected at the cashier. With the development of the economy, there are more and more small and medium-sized chain store...

Problems solved by technology

With the development of the economy, there are more and more small and medium-sized chain stores. For these stores, if they still use the first measurement, print out the individual strips, and then go to the cash register to scan the cash, one will cause inconvenience to customers, and the other will be For merchants, the two devices not only occupy a small space but also bring troubles in the management of manpower and material resources.

[0004] The formation of these problems is caused by the single function of the control module used in the existing equipment
