High speed paper counter based on image sensor

Abstract

The invention discloses a high-speed paper counter based on image sensor. The paper counter comprises a photoelectric integration module, a data transmission module, a data processing module, a man-machine interface and a power supply module, which match and are connected with each other. The photoelectric integration module comprises a linear image sensor; the data processing module comprises an A / D conversion chip capable of receiving the image information sent by the linear image senor and converting original image information into digital information; the data processing module comprises a universal programmable input output port capable of carrying out data exchange with the A / D conversion chip and the data processing module is connected with the man-machine interface through a transmission line; the power supply module is electrically connected with the photoelectric integration module, the data transmission module, the data processing module and the man-machine interface. The counter does not comprise any part concerning mechanical action and the counting process consequently does not comprise any mechanical action with convenient operation. The counter is applicable to counting paper with a thickness from 0.05mm to 10mm and the softness degree of a counting object does not affect the counting speed and accuracy of the counter.

Description

technical field

[0001] The invention relates to the technical field of electronic automatic counting, in particular to a high-speed paper counter based on an image sensor. Background technique

[0002] Paper counting is an important link that is often encountered in modern industrial production, especially in some traditional large industries such as printing and packaging. With the rapid development of the printing industry, the consumption of various types of paper has also increased significantly. The annual consumption of newspapers, books and various packaging and printing papers alone reached 59.3 million tons in 2005, with an annual growth rate of more than 13%. The speed increases, and the paper counter is an indispensable tool in the utilization process of these huge paper. But my country's current paper counting is mainly done by manual operation. This most primitive counting method is not only time-consuming, labor-intensive, and inefficient, but also prone to h...
