Problems solved by technology

[0005] Disadvantage: Each black and white block in the QR code can only transmit 1 bit information, which limits the transmission bandwidth
[0007] Disadvantage 1: QR code image refresh rate is low, limiting transmission bandwidth
[0008] Disadvantage 2: The QR code image refresh is not synchronized with the camera exposure time, and the image refresh rate is at least lower than 1 / 2 of the camera exposure frequency, which further limits the transmission bandwidth

Abstract

The invention relates to a high-efficiency multi-dimensional code-based machine vision communication system, which belongs to the communication field of dangerous goods production lines or storage operations. Including the sending end and the receiving end; and the sending end and the receiving end both include the following modules: LED multi-dimensional code display matrix, LED multi-dimensional code display control circuit, physical layer protocol analysis and processing module, multi-dimensional code decoder, sensor exposure synchronization control circuit and global Expose the high-speed sensor; among them, the modules with the same name in the sending end and the receiving end are the inverse process of each other. The invention can transmit multi-bit information in one information block; increase the image refresh speed and solve the synchronization problem of image refresh and visual sensor exposure.

Description

Technical field [0001] The invention relates to a machine vision communication system based on multidimensional codes, which belongs to the communication field of dangerous goods production lines or storage operations. Background technique [0002] Currently, wireless communication technology is widely used in the field of industrial automation. Compared with traditional wired communication technology, this technology does not require a physical route, effectively eliminating the cumbersome steps of laying cables, and eliminating the impact of complex industrial environments on wireless technology. However, many wireless communication technologies are subject to use restrictions during dangerous goods production lines or storage operations. WLAN communication has risks such as eavesdropping and data tampering; radio frequency technology has an impact on the performance of dangerous goods due to its radiation characteristics, leading to the occurrence of safety problems . Vision-...
