Abstract

The invention discloses a gigabit Ethernet transmission-based wide image scanning system and a realizing method thereof and solves the problems of slow data processing speed and complex structure of the existing wide image scanning system. The gigabit Ethernet transmission-based wide image scanning system comprises an upper computer, a gigabit Ethernet interface chip bidirectionally connected with the upper computer, a CPU (central processing unit) bidirectionally connected with the gigabit Ethernet interface chip and at least two CIS simulation front ends which are arranged in parallel, wherein each CIS simulation front end comprises a CIS light source driving module connected with the CPU, a CIS sensor connected with the CIS light source driving module, and a digital analog converter; the input end of each digital analog converter is connected with the output end of the corresponding CIS sensor and the output end of each digital analog converter is connected with the input end of the CPU. The gigabit Ethernet transmission-based wide image scanning system is simple in structure and high in intelligentized level, has the characteristics of large data processing capacity, fast processing speed and capability of stable long-distance transmission and is thus suitable for promotion.

Description

[0001] technical field [0002] The invention relates to a wide-width image scanning system, in particular to a wide-width image scanning system based on Gigabit Ethernet transmission and a realization method thereof. Background technique [0003] Wide format image scanning systems are mainly used for large format scanning in industry. With the continuous development and advancement of technology, the amount of data that the scanning system needs to process is also increasing, and often requires long-distance transmission. However, due to the insufficient design of the existing wide-format image scanning system, it is increasingly difficult to meet the progress of today's industrial development. Their shortcomings are mainly manifested in: (1) complex structure and high manufacturing cost; (2) processing The speed is slow, which leads to a long time to display the image, and the accuracy of the transmitted data cannot be guaranteed during long-distance transmission. ...
