摘要
列车广播系统基于CAN总线通信网络设计,通过音频通道,实现自动广播、人工广播和报警/对讲等功能,几列车联挂后,各车的广播系统成为一个系统协调工作。提出了一套地铁列车广播系统联挂设计方案,从列车广播系统介绍入手,逐渐展开提出了广播系统联挂过程的设计以及实现方法。列车广播系统的联挂设计主要涉及几个方面:通信系统联挂、广播通道联挂、对讲报警通道联挂。
Train broadcasting system is designed based on CAN bus communication network, functions such as automatic broadcast- ing, artificial broadcasting and alarm/intercom are achieved via audio channel. Broadcasting system of each car works as a overall system after coupling. A design scheme of coupling for metro train broadcasting system is proposed, starting from the train broad- casting system introduced, the design and implementation of coupling process for train broadcasting system is unfolded and put forward. Coupling for communication system, broadcasting channel and alarm/intercom channel are involved for train broadcasting system.
