Introduction to the EMU On board Communication System

摘要

The main function of the on board communication system of the TIAA MRT Project is to provide the needed communication tool for the control center, the train driver, or the passengers.The system functions and operating features are described below: A. Public Address system: the driver can personally broadcast to passengers on the train or automatically (for example: station name broadcast, pre-recorded message broadcast). B. Intercom System: In case of emergency, passengers can make calls via the emergency intercom to train drivers. If the train driver failed to answer the call within a preset time period (between 10 to 30 seconds), the call will be forwarded to the operation control center to be answered by designated personnel. Additional intercom capability is offered in the baggage car of the express train to allow communication between the baggage handling supervisor and the train driver.
