方案以IP广播对讲应急系统为核心,整合工業级终端、低延遲传输与智慧联动模組,实现前端触发、中层传输、后端调度、终端处置的完整闭环。方案遵循可靠性优先、易用性其次、面向扩展适配的原则,全面符合线路运营需求。

2.2 各层详细设计

2.2.1 前端求助终端层

所有终端均採用工業级產品,提供多樣化求助方式。EX-BT27防水对讲终端部署於月台,每側至少兩台,具備一键启动、防误触设计与语音提示。EX-BT30车载终端安裝於车厢內,每節车厢兩端各一台,具備抗震与抗干擾能力,可直接连接司机室,同時將求助信息推送至控制中心。求助QR Code張貼於车站醒目位置,乘客无需下載App即可扫码启动视频对讲。工作人员配備Becke HT-500手持终端,用於即時协同处置。

2.2.2 通信与网络层

系统採用冗餘设计。既有LTE-M车地专网用於列車与地面通信。车站终端通过具備双路由与双设备冗餘的LAN接入控制中心。行動终端使用4G/5G公網并通过VPN加密传输。整体网络符合行業標準,并配置防火牆与入侵偵測系统,确保安全与稳定。

2.2.3 后端服务平台层

核心平台为自主研發的IP广播对讲应急系统,部署於控制中心。平台採用微服务架構与双服务器热备份,整合六大核心模組,实现求助接收、音视频处理、定位显示、协同调度、至少30天数据儲存,以及智慧化运维,确保高可靠性与可扩展性。

2.2.4 应用与整合层

控制中心配置超高清指揮显示系统与调度台,工作人员手持终端则支援高效调度。通过多協議閘道,系统可与ISCS、广播、CCTV、110/120应急平台無縫整合,形成闭环协同机制,提升协同处置效率。
