Research on Key Technologies of Intelligent Detection of High-Speed Rail Pantograph Catenary Status Based on Image Fusion

Currently, the detection methods for overhead contact systems in China mainly use manual inspection and large-scale inspection vehicles. This method has problems such as high operating costs, interference with railway scheduling, high risk factors, poor real-time performance, and large workload. Pantograph catenary system is an important part of high-speed railway traction power supply system. Its dynamic characteristics and service status directly affect the operation safety of high-speed railway. This paper presents the key technology of intelligent detection of high-speed railway network status based on image fusion, which can complete the detection of pantograph arcing, pantograph anomaly, and pantograph carbon slide wear measurement. The experiment has proven that its operation efficiency is high, accuracy is high, workload is small, and risk factor is small, which is worth promoting and using.
