Abstract
With the intensive development of urban rail transit in China, urban rail transit has increasingly become the preferred mode of transportation for citizens due to its convenience and speed. The design and construction of an efficient and highly reliable urban rail transit system has become an urgent requirement for urban rail transit construction. This article mainly introduces the research and design of the data communication subsystem of the urban rail transit CBTC system, and intends to provide some ideas and directions for studying the data communication subsystem of the urban rail transit CBTC system. This article uses a variety of methods, such as consulting literature and information research on trademark system suppliers. The development status of CBTC system and data communication subsystem is analyzed, and the importance of data communication subsystem and the necessity of the entire CBTC system are analyzed. The experimental results of this article show that in the design, development and application engineering of the CBTC system, the DCS subsystem accounts for 55%, the system is complex, and the environment is changeable, occupying an important position. When the DCS has a problem, it may cause drive failure, affect normal functions, cause greater losses, and even cause huge safety accidents. Therefore, the reasonable, reliable and safe design of the DCS subsystem is of great significance.
Highlights
The experimental results of this article show that in the design, development and application engineering of the communication-based train control system (CBTC) system, the Data Communication Subsystem (DCS) subsystem accounts for 55%, the system is complex, and the environment is changeable, occupying an important position
As a safety computer system that ensures the failure of the communication-based train control system (CBTC), the safety of its derived data information is a necessary condition for the safe operation of the entire train
(2) Based on the theoretical basis of this article, the network data communication subsystem, wireless network and network security have been planned in detail, focusing on the design of wired backbone network, the design of wireless network access points, and the protocol standard design technology adopted by wireless networks
Summary
As a safety computer system that ensures the failure of the communication-based train control system (CBTC), the safety of its derived data information is a necessary condition for the safe operation of the entire train. His research is more one-sided and does not have a certain degree of persuasiveness (Shen et al (2016)) He L found that the operation of urban rail transit has moved from single-line to multi-line, urban transportation network operations have undergone quantitative and qualitative changes, and operation management is facing rapid internal and external changes. The innovations of this article are: (1) does it propose a brand-new intelligent rail transit system, it proves that the introduction of the communication system into the rigorous signal system provides a new development direction and performance improvement method for the development of the signal system. (2) Based on the theoretical basis of this article, the network data communication subsystem, wireless network and network security have been planned in detail, focusing on the design of wired backbone network, the design of wireless network access points, and the protocol standard design technology adopted by wireless networks
