Construction of Online Monitoring System for Track Safety and its Vibration and Noise

In accordance with the requirements of intelligent and scientific maintenance and repair for rail transit, the on-line monitoring and intelligent assessment technologies for infrastructure safety as well as vibration and noise indexes are studied. In connection with the line status of the Shanghai rail transit network, typical line sections are selected to lay out the online status monitoring equipment so as to track health and safety indexes of rails and real-time noise and vibration levels. By means of online real-time data collection and synchronous analysis technology, the Shanghai rail transit online monitoring system for track safety status and its vibration and noise takes shape, thereby achieving real-time monitoring for on-site vibration and noise as well as safety status, and providing assistant decision-making reports in connection with relevant index systems and in accordance with relevant time periods.

Shanghai Metro Constructs an “Intelligent Metro”

The World Artificial Intelligence (AI) Conference 2020 opened in Shanghai on July 9, 2020. The AI application scenarios presented by Shanghai Shentong Metro Group Co., Ltd. (Shentong Metro Group) have attracted a lot of attention of visitors. On July 9, 2020, the total passenger flow of Shanghai Metro exceeded 10 million, reaching 10.048 million, and Shanghai will enter the normal state of “ten million passenger flow” every day. At present, the operating mileage of Shanghai Metro reaches 705km, ranking first in the world. According to the new line planning and construction trend, the Shanghai Metro network will continue to expand, and there will be even more passenger flows in the future.

Talks of Shao Xinming, General Manager of Jinggang Metro, on the Application of New Urban Rail Technology

Recently, Shao Xinming, general manager of Beijing Jinggang Metro Co., Ltd. (Jinggang Metro), said in an exclusive interview with the journalist of Ta Kung Pao, the oldest active Chinese language newspaper in China, that urban rail transit has been clearly included in the category of “new infrastructure” and will provide more possibilities for residents to travel in the future.

Active Obstacle Detection System Based on Video Recognition and Lidar Information Fusion

In terms of the requirements for obstacle detection in the rail transit application field, an architecture and implementation method for active obstacle detection system based on the fusion of video recognition and lidar information is proposed. The studies on the video recognition algorithms based on deep learning neural network and lidar for orbit area recognition, pedestrian vehicle recognition, and small foreign object recognition are analyzed, and the necessity of the fusion of video recognition and lidar data and the related key technical points are discussed. Through the tests on domestic metro and tram lines, the feasibility of the scheme is verified, and the technical parameters are optimized, which can effectively reduce the probability of accidents caused by foreign object intrusion.

How Far Can You Travel by Metro for Five Yuan?

With 5 Yuan, you can buy a small piece of bread or two bottles of water. If you are thinking about travelling, public transportation will be the only option; and if you want to reach the destination quickly and comfortably, the metro will be your first choice. Then with 5 Yuan in hand, how far can you travel by metro? To answer this question, Shanghai Rail Transit Industry Information Center has collected the latest data on metro fares in 33 cities in China and drawn the chart, as shown in figure 1.

Overview of the Intelligent Operation and Maintenance System for Shanghai Rail transit Rolling Stock

The traditional rolling stock maintenance model based on planned repairs and fault repairs cannot meet the needs of the rolling stock operation and maintenance for superlarge-scaled networks. There is an urgent need to establish a highly automated and information-based rolling stock intelligent operation and maintenance system based on online monitoring. This paper introduces the composition, main functions and application situations for the Shanghai rail transit intelligent rolling stock operation and maintenance system as well as suggestions for further work related thereto so as to provide references for the development of the rolling stock intelligent operation and maintenance system of the rail transit industry.

A Location-Based Device Tree System for Rail Transit

As the Vehicle Branch of Shanghai Metro Maintenance Guarantee Co., Ltd. is making continued progress in refined management, it requires increasing fine data granularity, together with increasing needs for data analysis. Therefore, the existing serial-number-based device trees can no longer meet continuous increasing management requirements, which necessitates a new device tree system. This paper has proposed a new device tree system for rail transit. Based on the physical locations of rail transit devices, the system proposed can associate the location information with property information, equipment serial number, and fault trees. Hence a subway vehicle and fault management system based on device trees was established. Based on the actual situation and management requirements of the Vehicle Branch, this paper has developed a location-based device tree management system and coding scheme, and introduced its advantages in management.

Consideration on Construction and Development of Shanghai Smart Metro

The degree of intelligence and service level of urban rail transit has significant influence on the measurement of intelligent transportation. In this paper, the importance of smart metro development is discussed from the perspectives of national development background, technology development trends, and people’s basic requirements, and the features of smart metro in multiple levels are analyzed. On this basis, the construction target, system architecture, and construction methods of smart metro are put forward, and the applications of smart metro are elaborated from smart construction, smart operation and maintenance, and smart service.

Completion of multi-vehicle driverless test verification of Casco’s train operation system based on vehicle-to-vehicle communication

Late at night on June 28, 2020, Casco Signal Co., Ltd. (Casco) Train Autonomous Operation System (TACS) based on vehicle-to-vehicle communication successfully completed the unmanned driving test verification on Shanghai Rail Transit Line 3/4. Finally, all the verification indexes of the Casco vehicle-to-vehicle communication TACS system achieved the expected goals, and the system was highly praised by the review experts.

The integrated monitoring software platform for urban rail transit of “Hisense” has passed international safety certification

In early March 2013, Qingdao Hisense Network Technology Co., Ltd. (Hisense) independently developed the integrated monitoring system software platform for urban rail transit (HiSCADA), which successfully obtained the SIL2 product functional safety certification issued by the French BV International Inspection Bureau. This indicates that the safety performance of the integrated monitoring system of Hisense has fully met the international safety standards, and will provide a higher level of safety guarantee for the smooth operation of the system in the unmanned environment of urban rail transit.
