Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a weighing module conditioning circuit of a fruit sorting machine. Background technique [0002] In recent years, people's requirements for fruit quality have been continuously improved. At the same time, in order to improve the commercial value of fruits and expand the export of fresh fruits, strict quality classification of fruits has become particularly important. However, the productivity of manual grading is low and the sorting accuracy is unstable, so it is imperative to realize the mechanized and automatic sorting of fruits. [0003] At present, scholars at home and abroad have conducted a lot of research on the use of machine vision technology to detect the external quality of fruits, and have made significant progress. It is now possible to use machine vision technology to detect the size, color, surface defects, and fruit shape of fruits in real time, and the resul...
