Multifunctional high-precision weighing system based on virtual technology

Abstract

The invention provides a multifunctional high-precision weighing system based on a virtual technology. The multifunctional high-precision weighing system is formed in such a way that an instrument amplifier and an amplifier are used to carry out two-stage amplification on a weak signal outputted by a constant section cantalever type sensor, an analog-to-digital converter is controlled by a singlechip to perform analog-digital conversion on the amplified signal, meanwhile, a serial port communication level translator is used to conduct the level conversion on acquired data and then sends the acquired data subjected to the level conversion to a computer through a serial port, and functions of password authentifying, unit price setting, data processing, displaying, storing, transmitting and controlling are achieved through LABVIEW software.

Description

technical field [0001] The invention relates to a multifunctional high-precision weighing system based on virtual technology. Background technique [0002] The traditional measuring tools are steelyards or pan scales. With the continuous development of electronic technology, it is increasingly difficult for traditional weighing systems to meet people's needs in terms of function, accuracy, intelligence, and cost performance. The electronic scales that appeared in the 1970s began to show in all walks of life that they have high measurement accuracy, fast measurement speed, and easy-to-learn operation, and have replaced traditional mechanical lever measurement scales. With the continuous improvement of people's living standards, computers have entered thousands of households, and electronic scales are often finished products made in advance by merchants, which cannot be connected with current computers and have a single function. However, electronic scales that can communicat...

Problems solved by technology

With the continuous improvement of people's living standards, computers have entered thousands of households, and electronic scales are often finished products made by merchants in advance, which cannot be connected with current computers and have a single function.

However, electronic scales that can communicate with computers are expensive, difficult to maintain, and inconvenient to use.

At the same time, the current electronic scales are bulky, and the flexibility and convenience are severely limited, which also leads to a series of problems such as high power consumption and difficult maintenance.
