A network construction model of underground transportation hub safety monitoring center is proposed in this paper according to the disadvantages of present management mode in underground transportation hub. Taking transfer station from two different lines as an example, network analysis of the information transmission for BAS (Building Automatic System) and FAS (Fire Alarm System) which affect subway...
Railway traffic management is performed in an automatic way using centralized systems based on wired sensors and electronic elements fixed on the tracks. In spite of these systems, called Centralized Traffic Control systems (CTC), are robust and highly available, when they fail the traffic management must be done manually, increasing the probability of accidents due to the occurrence of human errors...
In contrast to classic train protection systems where most of the safety measures are built into the rail infrastructure, future versions of the European railway safety system ERTMS (European railway traffic management system) require trains to check their own safety. One of the safety measures is the train integrity check, which checks whether all carriages are still in the train. The check has to...
This paper discusses the design of a centralized control and monitoring system for railway traffic that can be implemented on top of the existing control logic (interlocking system) of Sri Lanka railways. The overall solution comprises of a central server system and databases with redundancy, relay house hardware unit (with embedded Ethernet and a custom communication protocol for microcontrollers)...
This paper discusses the architecture of a new system created to simulate a networking protocol called advanced train control system (ATCS). ATCS is a popular protocol used by railways to control track switches, relay sensor readings, and help improve safety. The new simulation environment plugs into the Network Simulator-2 (NS-2) framework, allowing the user to model railroad data networks. This...
Chinese train control system (CTCS) is one of real-time distributed supervising and control systems that have the distributed physical entities needing cooperation to accomplish their local goal, make possible decisions, execute actions, negotiate through the communication protocol to reach global criterion. For designing CTCS simulation software, the hybrid software agent model that is adapted to...
