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IoT传感平台，可实现真正的智能基础架构。它是简单，低成本，快速适应，免费维护并且能够在大多数位置感知，但是，通过其新颖的架构，对本地需求仍然非常灵活。它将允许基础设施托管人能够在以前无法获得电源或连通性的站点或以其成本过高的那些网站收集数据。基础架构所有者的好处是由收集有针对性且可操作的资产条件知识的新的便利性产生的，从而实现了许多资产类型的预测维护策略 - 可以直接传递给铁路用户的好处。光谱解决方案利用了现有的NR（网络导轨）光纤网络以及最近在其他部门找到商业应用的三种尖端技术的融合，但在英国铁路中尚未在英国铁路中进行：1）FOAS（1）FOAS（视觉传感）（视觉传感）（纤维的纤维发动机），在海外轨道和机油+气体中，可以通过在70km上的范围内进行调整，从而在海上轨道和机油+气体上进行调整，从而使“均可通过70km”的范围进行变化。波浪。它可以检测和定位声学事件，例如车轮平坦，电缆盗窃和侵入。 2）泥炭（压电电气传感器）在纤维上，通过鞘，传输数据。这些将集成到旨在与广泛传感器接口的节点中。 3）高效率光伏面板将在这些传感器节点上收集能量。加上智能电源管理时，即使在弱光或室内应用中，这也将允许使用10年的拟合式传感器寿命。结果是，FOA的本来有吸引力的功能与低成本点测量值相辅相成，具有感知几乎所有物质的能力，即NR纤维运行的任何地方，这超过了基础架构的90％以上。当NR需要进行新的点测量时，节点安装将与选择传感器并将小盒子剪切到纤维鞘一样简单。然后，FOA会自动定位并解释输出。该项目将通过首次在实验室中集成技术来证明该方法，然后在NR的RIDC Melton上安装端到端原型，以获取下一阶段产品接受阶段的主线测试证书。四个传感器将在15公里左右的范围内进行演示，其中包括在铁路环境中的两部小说：火灾检测（专有，基于事件）；涂鸦检测（专有，传感器融合）；地球器（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者。 AP感应是主要合作伙伴和系统集成器，提供FOAS系统和前端。 Lightricity将提供能源收集和管理系统，CSAC泥炭系统和Pyreos专有传感器解决方案。 NR电信正在提供工程资源并访问测试网站。
