Problems solved by technology

[0003] However, the detection of cement sleepers has been a problem that has plagued the development of high-speed railways for a long time. Each sleeper must undergo strict testing before it can be used by high-speed railways. The current detection method is human eye detection, which is not only labor-intensive, but also has low accuracy. , but also subject to the limitations of professionals, the production capacity is restricted

Abstract

The invention relates to a high speed rail cement sleeper detection system based on industrial vision. The high speed rail cement sleeper detection system based on industrial vision comprises a conveying line for conveying a cement sleeper, a cover bracket for covering the conveying line, and an industrial camera set arranged in the cover bracket and positioned over the conveying line, the industrial camera set is used for acquiring the surface image signal of the cement sleeper, and the system further comprises a PLC. Industrial cameras are combined with the PLC to substitute human eye detection in order to realize online detection of the high speed rail cement sleeper through visual scanning identification and detection identification of micro-cracks which cannot be identified or are difficultly identified by human eyes and record the data information of every high speed rail cement sleeper, so the system provides high security for the safety operation of high speed rails.

Description

technical field [0001] The invention relates to the field of machine vision and its application, in particular to a high-speed rail cement sleeper detection system based on industrial vision. Background technique [0002] In recent years, my country's high-speed rail technology has advanced by leaps and bounds, leading the world in terms of design, construction, and construction. At present, there are more than 1,300 high-speed trains in China, with a speed of 200 kilometers to 380 kilometers per hour. The quality requirements of the sleepers are very strict, even if there is a dimensional error of millimeters, it can cause the vibration of the train, so it needs to go through a series of strict procedures. [0003] However, the detection of cement sleepers has been a problem that has plagued the development of high-speed railways for a long time. Each sleeper must undergo strict testing before it can be used by high-speed railways. The current detection method is human eye d...
