PURPOSE: A wireless train calling system for an urban railway using a call voice signal is provided to enable an engineer to concentrate on a train driving operation by recognizing a call of a corresponding train with various methods and performing a wireless call. CONSTITUTION: An integrated control center(100) transceives various control signals for driving each train(400). A voice recognizing module(200) converts a specific voice signal among wireless signals of the integrated control center into digital data. A wireless train base station(300) delivers the wireless signals to each train and delivers an output signal of the voice recognizing module to each train. Trains are operated by the delivered signals and include a wireless unit interlinked with a calling unit except a speaker. |
