Research On Information Transmission Mechanism Of High Speed Railway Dispatching And Commanding System

In recent years, high-speed railway is developing rapidly in China; the high-speed railway has attracted more and more passengers aboard. The safe, fast and comfortable of high speed railway’s operation cannot leave the security of high speed railway dispatching and commanding system, and high speed railway dispatching and commanding system is a modern information system, there are the complex information flow and the various timing of information transmission, these bury a safety hazard to high-speed rail operations.Therefore, the research of high speed railway dispatching and commanding system’s information extraction and information transmission time is significative to guarantee safe and accurate operation of high speed railway in our country.In this paper, On the basis of the characteristics of high speed railway scheduling command, using the information entropy theory to construct the aging quality model for high speed railway dispatching and commanding system overall architecture’s comparison, and then to pick out the high speed railway dispatching and commanding system overall architecture as the research object to divide it into some subsystems and configurate its subsystems and scoping and analyze its function of subsystems.In this paper, starting from the core subsystem and the boundary subsystem, expounds the railway dispatching center to the primary-level organizations of information transfer and in the same railway dispatching center of information transmission and the information transfer between high speed railway dispatching and dispatching of existing, based on this, it concludes the information characteristics of the high speed railway dispatching and commanding system.This paper analyzes the principle of high speed railway dispatching and commanding system of information extraction, under the guidance of this principle put forward such as the high speed railway dispatching and commanding system’s information extraction method bases on is based on work breakdown structure, system clustering and grey correlation theory, and with the examples of the core subsystem of information extraction, the method are verified.In this paper,information transmission based on the analysis of high speed railway dispatching and commanding system’s status and the influence factors of information transmission timing, on the application of relevant knowledge of cognitive psychology and combining the actual situation of high speed railway dispatching and commanding system to build the high speed railway dispatching and commanding system’s information transmission model, the model of the calculation results show that the presented calculation methods for high speed railway dispatching and commanding system of information transmission timing has a certain guiding role, and summed up the high speed railway dispatching and commanding system on the timing of information transmission.
