System and method for detecting connector based on digital signal processor (DSP)

Abstract

The invention discloses a system and a method for detecting a connector based on a digital signal processor (DSP). A charge coupled device (CCD) vidicon is connected to a TVP5150 video decoder through a data link; a DM6437 chip is respectively connected with the TVP5150 video decoder, a FLASH register, a display and an MAX 3221 chip; and the MAX3221 chip is connected with an upper computer. Processing and judgment for images generated by the invention are carried out in a DSP chip with high-speed operation, thereby avoiding data loss caused by multi-transmission of the data; the DM6437 chip can operate for a long time, thereby avoiding logic confusion and execution error; a simple and efficient line detection algorithm can reduce arithmetic operations and improve accuracy; the system is small in volume, thereby being suitable for being installed on a plurality of production lines; and the system can reduce working difficulty of operators and improve working efficiency; therefore, the system and the method for detecting the connector based on the DSP is suitable for online detection in the production line of the connectors.

Description

technical field [0001] The invention relates to DSP image processing technology, in particular to a DSP-based connector detection system and detection method. Background technique [0002] DSP chip, also known as digital signal processor, is a kind of microprocessor with special structure. The interior of the DSP chip adopts the Harvard structure that separates the program and data, has a special hardware multiplier, widely uses pipeline operations, and provides special DSP instructions, which can be used to quickly implement various digital signal processing algorithms. It can be used in video security surveillance systems, in-flight entertainment systems, IP network cameras, video phones, portable media, and vision systems. [0003] In the connector industry, stamping and assembly procedures are mostly required for visual inspection. In most domestic enterprises, the quality inspection of each process in the manufacturing process is usually completed by specialized quali...

AI Technical Summary

Problems solved by technology

[0005] 1. The image acquisition is completed by the image acquisition card. The processing and judgment of the digital image are all completed on the PC. The image processing and transmission are not completed on the same module, which will cause data loss;

[0006] 2. The long-term work of the PC is prone to crashes and blue screens;

[0007] 3. The image processing and judging operation speed of the PC is not fast enough, and it is difficult to meet the complex processing and high-speed judgment;

[0008] 4. The PC is large in size and difficult to install in a narrow production line;

[0009] 5. The detection algorithm is complex, and the large amount of calculation seriously affects the efficiency
