Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1: referring to fig. 1, a locomotive pantograph carbon slide monitoring system relates to key technologies including an image real-time capturing technology, an image recognition and measurement technology, a data analysis and early warning technology, a big data analysis technology, and the like, and specifically includes the following steps:

1. image real-time capture technology: the high-speed and high-definition camera is adopted to track the locomotives entering the warehouse of each locomotive service section in real time, and when the locomotives passing through the monitoring point is captured, real-time images of the pantograph and locomotive information (such as locomotive numbers and the like) are automatically acquired.

2. Image recognition technology: and carrying out background processing on the acquired photos and images. Different weather conditions, such as the different angles of illumination of sunshine, light, like haze concentration, visibility etc. again, all can influence the picture image of photo. Therefore, it is necessary to perform background noise removal processing on the obtained photographs so as to minimize the noise caused by weather conditions and environmental conditions. Meanwhile, the pantograph picture is also full of background impurities (namely, the content which is not required by the processing of people is not needed), therefore, people need to remove the background impurities, only keep the image of the pantograph (locomotive information), and process and convert the picture image into the image of the pantograph only so as to ensure the reliability of the subsequent processing.

3. Graph analysis processing and measurement technology: after background and impurity treatment, the image can be subjected to three-dimensional perspective transformation through a related algorithm, and the obtained pantograph graph is restored into a standard graph. And comparing the graph of the original standard with the graph collected in real time to find out the difference. The wear of the carbon slide was measured using image measurement techniques (theoretically, the pantograph brackets should not be worn, and the amount of wear of the carbon slide could be known by comparing the differences with the carbon slide). Meanwhile, the images of the locomotive information are identified to confirm the corresponding locomotive information.

4. Analyzing and early warning the wear condition of the pantograph: quantitative analysis can be performed through the difference between the CAD graph given by the graph analysis and the graph collected in real time, the maximum abrasion loss of the carbon sliding plate is given, the abrasion loss is compared with the set lower threshold, the conclusion whether the carbon sliding plate needs to be overhauled and replaced is given, and maintainers are reminded to inspect and replace the carbon sliding plate.

5. Big data analysis application: and analyzing according to the wear trend of the carbon sliding plate and historical use data, predicting the service life of the carbon sliding plate, and guiding to make a replacement plan. Meanwhile, the system can be combined with data of other systems to perform combined analysis, and the quality, the line condition and the like of the carbon sliding plate are analyzed.
