Ethernet strip steel surface image data processing platform based on DSP

Abstract

The invention provides an Ethernet strip steel surface image data processing platform based on DSP, comprising a DSP chip, a PLL clock circuit, a program memory, a data memory, an Ethernet control circuit, a power module and a CCD camera. The DSP chip uses DSP chip DM648 of an IT company as a core processor of the processing platform. The DSP chip is connected with the program memory via an external memory interface of the chip; the data memory is connected with a dynamic memory special control interface of the DSP chip via data bus; the Ethernet control circuit is directly connected with an EMAC interface of the DSP chip. The processing platform of the invention could improve access speed of the DSP chip to image data, collect the image of the CCD camera with the Ethernet control circuit, and process the image with the DSP chip. The processing platform of the invention not only greatly improves the integration level of the system, but also reduces the system cost so as to be suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of Ethernet data communication and processing of an embedded system, in particular to a DSP-based Ethernet strip steel surface image data processing platform. Background technique [0002] With the increasing competitive pressure of iron and steel enterprises, the requirements for the surface quality of strip steel are also constantly increasing, and the strip surface quality inspection system has become an indispensable equipment for improving the quality of strip steel and enhancing the competitiveness of iron and steel enterprises. In the field of industrial data acquisition systems, the requirements for all aspects of data transmission are getting higher and higher. Industrial Ethernet has become the current industrial remote data communication system with its high-speed data transmission, reliable and stable technology and the advantages of long-distance communication. preferred way. [0003] Due to its real-tim...
