Abstract: The pantograph video monitoring system is essential for monitoring the status of high-voltage equipment of the rolling stock, which plays a vital role in improving the high-voltage system. It plays a crucial role in improving the efficiency of fault disposal and ensuring the operational safety of rolling stock. The system can effectively assist the train mechanic in carrying out emergency treatment of high-voltage equipment failure, which improves the disposal efficiency and compresses the stopping time. The degree of intelligence is not high for the system currently exists, relying on manual monitoring and inspection, by the outside environment interference, snow and ice weather use inconvenience and other problems. We propose using extensive data analysis, image intelligence analysis, and other technologies to optimize and improve system functions. As a critical rolling stock component, it will lose its power supply when the pantograph fails. Not only does it cause the train set to lose power and stop in the interval, but also the passenger service facilities such as air conditioning, water supply, and sanitation will stop working. Seriously affect the comfort of the passenger. To improve the efficiency of high-voltage system fault disposal and ensure the safety of the rolling stock, this system plays an important role in ensuring the safe operation of moving trains and maintaining the order of high-speed rail transportation.

Abstract: The paper briefly introduces the principle and application status of the video monitoring system for the EMU coaches by introducing the video monitoring server, coach camera, pantograph monitoring camera, monitoring screen, and other significant equipment configuration and parameters, describing The current status of the video CCTV system of EMU coaches, combined with the current development status of the EMU and the application prospect.

With the continuous development of railroad informatization in recent years, the locomotive onboard safety and protection system data has become an essential source of operational information for locomotive operation, maintenance, preparation, etc. However, in the dumping of inspection data, it is necessary to manually use the dumping device in the preparation workshop, which is time-consuming, labor-intensive, and prone to errors and omissions. When locomotives are put into storage at night, the energy and physical strength of the preparation personnel decreases, which inevitably causes a decline in operating standards and even labor safety problems. There are cases when the cause of an accident cannot be confirmed due to analog video during the ground analysis of video data. Unable to ensure the proper locomotive operation

The onboard video surveillance of locomotives and vehicles has become a management method to improve the safety of locomotives and regulate the driving behavior of flight attendants. Currently, the use and analysis of these video data mainly rely on manual viewing, which has high labor costs and low efficiency and may cause omissions due to human negligence. So our company develops an intelligent analysis system for locomotive crew operations audio and video, which can automatically analyze and identify violations and significantly improve the efficiency of video analysis.

The system uses a 60GHz high-frequency millimetre wave, which has the advantages of mature technology, large bandwidth, no spectrum application, and low interference far away from common civilian frequency points. In traditional wireless communication, its oxygen-degradation transmission characteristics make it difficult to transmit over long distances, and its application is limited. At the same time, this feature fits the needs of short-range communication and signal leakage prevention in vehicle-to-ground backhaul scenarios.

Locomotive automatic video monitoring and recording subsystem, as an essential part of the railroad security system, can maximize the prevention of various crises and protect the safety of railroad operations. However, the existing system's onboard video is analog, and the video resolution and picture quality can no longer meet the high requirements of the scene. To solve this problem, Shandong Tienuo Intelligent Co.,ltd Achieve a systematic upgrade from analog video to digital HD video for this problem.

Mobile video surveillance cameras have been an indispensable tool in ensuring safety and security on trains. These cameras provide real-time surveillance of train compartments and help in investigations. Mobile video surveillance cameras have become smaller, more reliable and cheaper, making them easier to use for train operators of all sizes. It is crucial to protect the privacy rights and ensure the responsible use of data. Mobile video surveillance cameras are an important addition to train security and safety measures. They should be promoted.

The CRH series has been the basis for continuous innovation in high-speed trains in china. Pantograph as a crucial electrical connection component have also evolved in this process.The pantographs play a important role in receiving high power from the contact network for the single-phase AC 25kV high voltage power required by the rolling stock. The total traction power required by high-speed trains is much greater than that of ordinary trains. At higher speeds, the air resistance also increases. Considering the requirements of reducing air resistance and noise, the number of pantographs on high-speed trains should not be too many. For 8-car trains, China adopts the single-arch pantograph method, i.e., only one pantograph is used during the operation of the trains and considering the requirements of reliability and redundancy, two pantographs are installed on each train. When the rolling stock is in process, one of the pantographs can be selected to be raised and the other pantograph folded.

The system carries out intelligent automatic analysis of locomotive video, realizing the whole process of traceability of crew standardization operation and driving safety and escorting the production of safe railroad transportation.

Abstract: The pantograph is a critical component that connects the rolling stock to the power supply grid, so the safety status of the pantograph is vital to the smooth and stable operation of the rolling stock. In this paper, by analyzing frame by frame, the pantograph video images monitored by the on-board video monitoring system, the safety status of the pantograph is monitored in real-time by modifying the YOLOV3 target recognition algorithm widely used in industry to identify structural abnormalities, sparks, and foreign object intrusion of the pantograph at the same time. Experiments have proven that a single channel can reach 40fps on a Tienuo on-board intelligent analysis server. The comprehensive detection accuracy mAP@0.5 can get 98%, achieving real-time and relatively accurate detection results.

The intensity of the war between Russia and Ukraine is expanding beyond the battlefield. Following the financial sanctions marked by SWIFT, the IT, automotive, chemical, media, sports, education, and entertainment sectors have also been sanctioned one after another, up to the "cut-off" sanctions in the energy sector. Recently, the rail sector has joined the ranks of these sanctions. The International Union of Railways UIC has kicked former Russian Railways RZD, Belarusian railroad company BCh kicked out of the UIC membership list. The war between Russia and Ukraine is expected to significantly impact the rail industry in the coming years, not only in Europe, and Azure Track Rail brings you a complete analysis.
