综合乘客信息系统 (PIS)
现代乘客信息系统（PIS）不仅仅是一块显示屏，它是一套由硬件与软件组成的集成网络，既能向乘客推送准确的实时信息，同时采集重要的车载数据，为运营决策提供依据。
它既包含在乘客出行全程为其提供信息提示的可视化设备，也涵盖用于主动安全监控以及满足法规合规要求的视频录制系统。
凌华的一体化乘客信息系统产品系列通过两大关键层级满足上述核心需求：
- 显示层：坚固耐用、高可视度面板，实现与乘客的无缝交互沟通。
网络视频录像机层：搭载人工智能的网络视频录像机，用于车载智能安全防护与事件记录。
凌华科技的乘客信息系统解决方案专为最严苛的铁路环境打造，完全符合EN 50155标准，经过实地验证，获得全球一线铁路运营商的信赖。

凌华科技PIS解决方案：常见问题
产品与系统设计
A: 乘客信息系统（PIS）是一套完整的车载生态系统，包含显示器、服务器、摄像头以及网络基础设施；乘客信息显示系统（PIDS）特指乘客信息系统（PIS）内部的显示层。.
A:Standard models: ARD-R2150 (21.5”, 1000 nits) and ARD-RS2860 (28.6” stretched type); Custom configurations are available via ADLINK's ODM services.
A:ADLINK's PIDS displays can be equipped with optical enhancements such as anti-glare and anti-reflective coatings to maintain excellent readability under various lighting conditions, including direct sunlight, station platforms, and underground environments.
A:The AVA-7200 is a fanless, EN50155-compliant edge AI platform. It receives video from onboard IP cameras via M12 Ethernet, records to modular SATA storage.
A:Up to 8 simultaneous IP camera channels via its M12 PushPull x-coded Ethernet ports.
认证与合规
A:EN50155:2021 (onboard electronics), EN45545-2 (fire protection), and IEC 62443-4-1 (cybersecurity). These cover vibration, shock, extended temperature, EMI/EMC, and fire behavior requirements.
A:EN50155 validates that a product can reliably operate in the electrical and mechanical environment of a moving train — covering temperature, humidity, vibration, shock, power variations, and EMC.
A:Yes. Both the AVA-7200 and ARD PIDS series are designed and tested to EN45545-2, which governs the fire behavior of materials used in railway vehicles.
定制与ODM服务
A:Yes. ADLINK offers full ODM customization — from modified standard products to fully designs — covering display size, housing, glass, mounting, brightness, and software.
A:45 days from design confirmation, enabled by ADLINK's in-house manufacturing and direct access to AUO Display Plus panel technology.
A:AUO Display Plus supplies transportation-grade display panels that form the foundation of ADLINK's PIDS solutions. By combining AUO's railway-focused display technology with ADLINK's rugged computing and system integration expertise, we provide a complete, single-vendor solution that simplifies procurement and accelerates project deployment.
