Problems solved by technology

However, the current image processing technology is mainly implemented based on the software platform. Due to the lack of processing speed of the software platform, it cannot meet the real-time requirements in the real environment. Therefore, the use of hardware platforms to realize image processing technology has gradually become the current Research Hotspots

Abstract

The invention discloses an on-line detection system and method for the winding space of a twisted pair. The system comprises an image acquisition device, an FPGA (field programmable gate array), an SDRAM (synchronous dynamic random access memory), a display and a terminal, wherein the FPGA comprises a NiosII processor, a VGA controller and an SDRAM controller, the image acquisition device acquires an image of the twisted pair in real time and sends the image to the NiosII processor to serve as an original image, the NiosII processor processes the original image to obtain the processed image and performs calculation on the basis of the processed image, and the winding space of the twisted pair is obtained. The on-line detection system and method have the advantages that the image is processed in the FPGA, the problem of poor timeliness due to the fact that a serious of processes such as image saving, compression, decompression and the like are required for image processing in existing software platforms and cause signal delay is solved, and therefore, the on-line detection method for the winding space of the twisted pair is ensured to have higher real-time processing capacity.

Description

technical field [0001] The invention relates to a detection system and method, in particular to an on-line detection system and method for twisted-pair winding distance. Background technique [0002] With the rapid development of the Internet, the transmission speed of the Internet is also getting faster and faster. As the main transmission tool of the Internet, the network cable usually includes a pipe body and a twisted pair arranged on the pipe body. The faster the transmission speed of the network cable, the greater the crosstalk inside the twisted pair. In order to ensure the high-speed transmission quality requirements of the network cable, it is necessary to control the crosstalk of the twisted pair within a certain range during the production process of the network cable. The main factor that determines the crosstalk of the twisted pair is the winding distance of the twisted pair. At present, the crosstalk is mainly controlled by controlling the winding distance of...
