Research on Rail Transit Dispatcher Emergency Decision Support Based on Case Similarity Matching

Abstract

To alleviate decision-making pressure on rail transit dispatchers in the emergency handling process, this work sorts out the scenario elements of rail transit emergency cases, establishes a scenario element system, and uses the information weight method to determine the weight of each scenario element. Based on the information of the key decision points, the complete process of emergencies is divided into various scenarios, and an emergency case representation model is constructed. The model establishes a database of historical emergency cases in rail transit, utilizes the scenarios as the search object to match the similarity of emergencies, and provides the decision-making support information to handle the current emergencies. Furthermore, the model constructed in this paper is subjected to an actual emergency case for analysis and calculation, which verify the validity and feasibility of the proposed model.

Research on rail intelligent security system based on YOLO

“…Wang S C et al significantly improved the detection method of railway foreign body intrusion by using the YOLO v3 network and improved the operational efficiency of railway detection [1]; Huang Tao et al applied machine vision technology to the speed measurement and positioning system of urban rail transit, and its efficiency was significantly higher than the existing equipment [2]; Cheng S et al loaded the inertial navigation system and global navigation satellite system onto the train motion model and conducted simulation experiments [3]; Liu X K et al proposed a fiber optic positioning speed measurement system, which uses fiber Bragg grating sensors to locate and measure train speed [4].The above methods have the advantages of high positioning accuracy, but the disadvantages are high cost and difficult implementation. This paper proposes a high-speed maglev positioning system based on image recognition, which uses deep learning technology to locate the train and can directly locate the train through the monitoring system on both sides of the track.…”

Function Analysis of Urban Rail Transit Smart Station

“…Subway stations have also begun to adopt facilities and equipment such as intelligent lighting, intelligent security, intelligent comfort service, intelligent entertainment system, and intelligent passenger flow statistics and analysis. Through the use of various facilities, passengers can share and exchange information with the subway operation and dispatch center [1][2][3][4][5][6] . At present, many cities in China have begun the construction of smart transportation systems in urban rail transit networks.…”
