Description

technical field [0001] The invention discloses an electronic scale, in particular to a commercial barcode electronic scale for automatic item identification and an item automatic identification method. Background technique [0002] The barcode electronic scale is a built-in portable barcode printer based on the ordinary electronic scale. The measurement information printing format of the product is set, and the barcode paper can be cleaned and printed out when in use. When the item is placed on the weighing pan, the pressure of the item is applied to the Pressure sensor, the sensor is deformed, so that the impedance changes, and at the same time, the excitation voltage is changed to output a changed analog signal, and the signal is amplified by the amplifier circuit and output to the analog-to-digital converter, and converted into a digital signal output that is easy to process To the CPU calculation control, the CPU outputs the results to the display according to the keyboa...
