EtherCAT master station integrated with camera and working method

Abstract

The invention discloses an EtherCAT master station integrated with a camera. The master station comprises a processor, a communication module, a visual module, a display module, a power module and a storage module. The visual module is combined with the EtherCAT master station, a first processing unit reads an image collected by the visual module and stores the image in the storage module, a second processing unit reads the video image stored in the storage module and then processes the video image, and a processing result is sent to an on-chip memory and is called and used by a third processing unit provided with an EtherCAT main station program, so that the signal interference and transmission delay caused by a common UDP protocol of the industrial camera are avoided. During the image processing process, the first processing unit is adopted for hardware acceleration, and the image processing performance is improved; and the third processing unit only runs the EtherCAT master stationprogram, and the Ethernet frame transceiving is realized by the first processing unit, so that the performance and the reliability of the EtherCAT master station are optimal. The EtherCAT master station provided by the invention realizes the characteristics of embedding, high performance, information interaction, computer vision, industrial Ethernet and the like.

Description

technical field [0001] The invention relates to the fields of industrial field bus and vision processing, in particular to an EtherCAT master station system based on vision technology and heterogeneous processor technology. Background technique [0002] The future development trend must be embedded, diversified, and high-performance fieldbus solutions, and the real-time Ethernet bus must become a development trend in the field of industrial control. EtherCAT real-time Ethernet has the following advantages: precise synchronization cycle, higher data throughput, good compatibility and openness. [0003] In recent years, in order to meet the needs of internal information formation and comprehensive automation of factories and enterprises, major companies have adopted the industrial Ethernet bus protocol. However, the implementation cost of fieldbus is generally relatively high, and the development difficulty is relatively large, which hinders the development of fieldbus techno...

AI Technical Summary

Problems solved by technology

[0004] A good set of EtherCAT master stations must have sufficient real-time performance and complete functions. The performance of most existing EtherCAT master stations can only reach a synchronous clock of tens of microseconds, and the functions are relatively single, and only support the expansion of IO ports.

At present, the research on the Ether CAT master station with integrated camera at home and abroad is still in the exploration of theory and method, there is no systematic standard and perfect solution, especially how to improve the computing performance and the specific implementation is the most controversial
