基于ATmega8-A的乘客紧急通信单元的设计与实现

Design and implementation of the passenger emergency communication unit based on ATmega8-A

随着城市轨道交通的迅猛发展,地铁列车的安全性与舒适性越来越成为乘客关注的重大议题,其中保障通信顺畅是确保列车安全运行的重要环节之一。本文针对上海地铁三号线阿尔斯通轨道列车的乘客紧急通信单元不足之处,提出了一套以ATmega8-A为控制核心的解决方案,并给出了乘客紧急通信单元的硬件设计和软件实现方法,旨在为轨道列车技术国产化尽微薄之力。

With the rapid development of urban metro systems, safety issues of metro trains have gradually become a big concern among passengers. Securing smooth communications is one of the key components to ensure safe operation of trains. Focusing on the deficiencies of current PECU （Passenger Emergency Communication Unit） of Alstom metro trains running on Shanghai Metro Line 3, this paper proposes a series of solutions based on Atmega8-A as the control kernel and offers the hardware designs of PECU and the realization methods of software.
