based on 5G+ train data dumping system security gateway and high-speed buffer pool.

In recent years, with the continuous development of railroad information technology, the integrated use of onboard data to ensure the quality of locomotive maintenance also provides a solid basis for the benefit of standardized operations. However, the stability of the existing system's single link channel and hard disk leads to the loss of video and other data. At the same time, in the dumping of data, it needs to be dumped manually on board, which is time-consuming and laborious, but also easy to make mistakes and omissions, and sometimes there are security risks. In response to the above problems, the "5G+-based Data Dump Solution for Aircraft Service 6A System" realizes high-speed automatic download and upload of data for Aircraft Service 6A System through an advanced 5G+ network, dual storage, and redundant backup. This ensures the data's security and reliability, lays the foundation for data analysis, and is the ideal solution for vehicle-to-ground data transmission.

The impact of 5G technology on rail CCTV systems

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.

How to improve the data use and analysis of onboard CCTV System for rolling stock?

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.

Overview of pantographs for China EMU

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.

5G Train-to-ground data high-speed transmission subsystem

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

IMPROVED YOLOV3 ALGORITHM for Pantograph safety state detection

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.
