Spectrail is an IoT sensing platform which enables truly intelligent infrastructure. It is simple, low cost, fast to fit, maintenance free and able to sense at a majority of locations, yet, through its novel architecture, remains very flexible to local requirements. It will allow the infrastructure custodian the ability to collect data at sites previously inaccessible to power or connectivity, or at those deemed too high cost. The benefits to the infrastructure owner arise from a new ease in collecting targeted and actionable asset condition knowledge, enabling a predict-and-prevent maintenance strategy across many asset types - benefits which can be passed directly to rail users. The spectrail solution leverages the existing NR (Network Rail) fibre optic network alongside a fusion of three cutting edge technologies recently finding commercial applications in other sectors, but not yet in UK Rail: 1) FOAS (Fibre Optic Acoustic Sensing), deployed in overseas rail and Oil+Gas, is a central processor which can 'listen' over a 70km range by observing minute changes in light transmission caused by fibre movements, e.g from sound waves. It can detect and localise acoustic events such as wheel flats, cable theft and trespass. 2) PEAT (Piezo-electric acoustic transducers) 'tap' on the fibre, through the sheath, to transmit data. These will be integrated into nodes designed to interface with a wide range of sensors. 3) High efficiency photovoltaic panels will harvest energy at those sensor nodes. When coupled with smart power management, this will allow a 10 year fit-and-forget sensor lifetime even in low light or indoor applications. The result is that the already attractive functions of FOAS are complemented with low cost point measurements, offering the ability to sense almost anything, anywhere in the vicinity of where NR fibre runs, which is over 90% of infrastructure. When a new point measurement is required by NR, node installation will be as simple as selecting a sensor and clipping a small box to the fibre sheath. FOAS then automatically locates and interprets the output. This project will prove out the approach by integrating the technologies in the laboratory for the first time, then installing an end-to-end prototype at NR's RIDC Melton to obtain mainline test certificates for the next stage of product acceptance. Four sensors will be demonstrated at around a 15km range including two novel in the rail environment: Fire detection (proprietary, event-based); graffiti-in-progress detection (proprietary, sensor fusion); Geophones (COTS, continuous) and Rail temperature (COTS, periodic). Five partners will collaborate to deliver the demonstrator. AP Sensing is the lead partner and system integrator, providing the FOAS system and front end. Lightricity will provide the energy harvesting and management system, CSAC the PEAT system, and Pyreos the proprietary sensor solutions. NR Telecom are providing engineering resources and access to the test site.

Spectrail 是一个物联网传感平台，可实现真正的智能基础设施。它简单、成本低、安装快速、免维护，能够在大多数位置进行感应，但通过其新颖的架构，仍然非常灵活地满足当地要求。它将允许基础设施托管人能够在以前无法通电或连接的站点或被认为成本过高的站点收集数据。基础设施所有者的好处在于可以轻松地收集有针对性的、可操作的资产状况知识，从而实现跨多种资产类型的预测和预防维护策略 - 这些好处可以直接传递给铁路用户。 Specrail 解决方案利用现有的 NR（网络铁路）光纤网络，并融合了最近在其他领域找到商业应用（但尚未在英国铁路）的三种尖端技术： 1) FOAS（光纤声学传感），部署在海外铁路和石油+天然气，是一个中央处理器，可以通过观察光纤运动（例如声波）引起的光传输的微小变化来“监听”70公里的范围。它可以检测并定位声音事件，例如车轮扁平、电缆盗窃和侵入。 2) PEAT（压电声换能器）通过护套“点击”光纤来传输数据。这些将被集成到设计用于与各种传感器连接的节点中。 3) 高效光伏板将在这些传感器节点处收集能量。与智能电源管理相结合，即使在弱光或室内应用中，传感器也能实现 10 年的“安装即忘”使用寿命。结果是，FOAS 已经很有吸引力的功能得到了低成本点测量的补充，提供了感知 NR 光纤运行区域（占基础设施的 90% 以上）附近任何地方的几乎任何物体的能力。当 NR 需要进行新的点测量时，节点安装将非常简单，只需选择传感器并将一个小盒子夹在光纤护套上即可。然后 FOAS 自动定位并解释输出。该项目将通过首次在实验室集成技术来验证该方法，然后在 NR 的 RIDC Melton 安装端到端原型，以获得下一阶段产品验收的主线测试证书。将在大约 15 公里范围内演示四个传感器，其中两个在铁路环境中新颖： 火灾探测（专有，基于事件）；正在进行的涂鸦检测（专有，传感器融合）；地震检波器（COTS，连续）和轨道温度（COTS，周期性）。五个合作伙伴将合作交付演示程序。 AP Sensing 是主要合作伙伴和系统集成商，提供 FOAS 系统和前端。 Lightricity 将提供能量收集和管理系统，CSAC 将提供 PEAT 系统，而 Pyreos 将提供专有传感器解决方案。 NR Telecom 正在提供工程资源和测试站点的访问权限。
