SPECTRAIL - Low cost intelligent infrastructure through fibre acoustic transmission.

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，低成本，快速安装，免维护，能够在大多数位置感知，然而，通过其新颖的架构，仍然非常灵活地满足当地需求。它将允许基础设施管理员在以前无法使用电力或连接的地点收集数据，或者在那些被认为成本过高的地点收集数据。基础设施所有者的好处在于，收集有针对性的、可操作的资产状况知识变得更加容易，从而可以在许多资产类型中实现预测和预防维护策略，这些好处可以直接传递给铁路用户。频谱解决方案利用现有的NR（网络铁路）光纤网络以及最近在其他领域发现商业应用的三种尖端技术的融合，但尚未在英国铁路：1)FOAS（光纤声学传感），部署在海外铁路和石油+天然气中，是一个中央处理器，可以通过观察光纤运动引起的光传输的微小变化来“收听”70公里范围内，例如来自声波。它可以检测和定位声音事件，如车轮扁平，电缆盗窃和非法侵入。2) PEAT（压电声换能器）“轻拍”光纤，通过护套传输数据。这些将被集成到设计用于与各种传感器接口的节点中。3)高效光伏板将在这些传感器节点收集能量。当与智能电源管理相结合时，即使在低光或室内应用中，这也将允许传感器使用寿命长达10年。结果是，FOAS已经具有吸引力的功能与低成本的点测量相辅相成，提供了在NR光纤运行的附近几乎任何地方感知任何东西的能力，超过90%的基础设施。当NR需要一个新的点测量时，节点的安装就像选择一个传感器和将一个小盒子夹在光纤鞘上一样简单。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risc 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。四个传感器将在大约15公里的范围内进行演示，其中包括两个用于铁路环境的新颖传感器：火灾探测（专有的，基于事件的）；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器。AP传感是主要合作伙伴和系统集成商，提供FOAS系统和前端。lightity将提供能量收集和管理系统，CSAC提供PEAT系统，Pyreos提供专有传感器解决方案。NR电信提供工程资源和测试现场的接入。

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.
