Under normal conditions, the wear of the carbon slide plate is more uniform and it will be changed when the carbon slide wears to its limit. When the locomotive is running, it will inevitably produce sliding friction between the pantograph and the catenary. In order to ensure the safe operation of the train, it is extremely important to detect the state of the pantograph. The existing locomotives generally rely on the power system as traction power, in the system of which the pantograph serves as a key part. At the same time, China’s passenger and freight traffic is also increasing. For example, with the fast development of the high-speed train, railway mileage in China has maintained rapid growth. Original 2D information cannot meet the requirements of providing enough details for automatically evaluating by computer. In terms of traditional traffic, specific key parts with mess data need to be monitored in detail, which requires more manpower or more artificial intelligence. The development of calibration technology and three-dimensional registration technology has greatly promoted the application of three-dimensional measurement. Meanwhile, 3D data is more intuitionistic than 2D in visualization layout. The emergence and development of 3D laser measurement technology provide a new technical means for the acquisition of spatial 3D information, which can obtain more information about the shape of the measured object and improve measurement precision and accuracy. In recent years, with the development of 3D sensor imaging technology and data processing technology, 3D vision technology has become the focus of the development of the computer field, which has attracted extensive attention and research. In addition, a sound detection effect can also be obtained. The experimental results indicate that it is feasible to adopt 3D measurement technology to detect the fall-block of the pantograph slide.
Therefore, this paper studies the detection of the pantograph slide block based on 3D sensor measurement technology. At present, few studies have been conducted on the slide block and partial wear of the carbon slide. The three-dimensional data can not only obtain more information but also reduce the data deviation, thereby improving the measurement accuracy and work efficiency. The emergence and development of structured light measurement technology with 3D sensors provide new technical means for the acquisition of spatial 3D information.
In general, the pantograph carbon slip detection items include slide wear detection, slip strip crack detection, carbon slip fall-block detection and slip strip wear detection. As an important part of the electric locomotive in railway transportation, the sensing and inspection of the pantograph has a significant effect on the safe operation of the train.
