Research and implementation of urban rail traffic signal based wireless communications platform

摘要

Moving block system is one of the traffic signal system application technology urban rails, usually based train control (CBTC) communication to achieve, there are mainly inductive loop, wireless spread spectrum in two ways.,Wood IEEE standard text on the basis of combined engineering practice at home and abroad on the urban rail traffic signal data transmission system is studied, the definition of a data transmission system, function, working principle, design requirements. As well as the problems of engineering analysis, by analyzing the device configuration, frequency planning, electromagnetic interference and engineering test solved; the results show that the application meets the existing project.
