BROADCASTING CONTROL METHOD

摘要

A broadcasting control method for passengers in a high-speed railway is provided to collectively control broadcasting devices of each compartment if a driver or crew demands broadcasting while the railway is driven, and of conducting alarm control and amplifier control before the broadcasting, thus the broadcasting for the passengers is smoothly performed. If a broadcasting request signal is applied to a power car's VCU(Vehicle Control Unit) from a broadcasting device of the power car, a broadcasting permission signal for passengers is outputted to the corresponding broadcasting device. A display lamp-on signal for turning on a display lamp is outputted during broadcasting. A driver's on-air signal is transmitted to VCUs of all compartments connected through a network.
