Railways

PrismaRail, Prisma’s next-generation smart solution for railroad monitoring, uses its patented Hyper-Scan Fiber-Sensing™ technology enabling ultra-sensitive and intelligent-learning detection to provide real-time intelligence and uniquely reliable surveillance of the railroad tracks, trains, and everything in their proximity.

PrismaPower, Prisma’s next-generation smart solution for electric power transmission networks

The solution improves railway transportation monitoring and safety by facilitating faster and better processes for maintaining and protecting smart railways and trains – while lowering deployment costs using standard, pre-deployed fiber-optic cables (including cables installed within a conduit or concrete ditch). These fiber-optic cables, which are part of most modern infrastructures, operate as the system’s “sensors” and enable PrismaRail to monitor and detect the railway environment at remote locations, providing surveillance and real-time threat detection for up to 100 km per PrismaRail unit or 200 km per dual-unit.

PrismaRail identifies the acoustic signature of each event at or near the railway lines, at a resolution that allows classification of the events and identification of their location with unprecedented accuracy and dramatically reduces the “noise” of false positive and negative alarms. 

Within a distance from the railway line environment that you pre-define, PrismaRail allows smarter, faster railway management and monitoring while preventing accidental, criminal or malicious activity by flagging for classification a range of events that can include:

  • Real-time, accurate location of all trains on the rails

  • Rockfall and landslide events

  • Fallen trees near the train tracks

  • Trespassing

  • Intruders into the train track area 

  • Breakdown of train wheels

  • Journey time between defined locations 

  • Average speed

  • Vandalism

Solution Architecture

PrismaRail’s platform is Plug & Play – with zero infrastructure installation, and minimal maintenance. 

 

The platform provides monitoring for up to 100 km per PrismaRail unit or 200 km per dual-unit. The unit is connected to a single Command & Control (C&C) unit located in the customer’s operating center. 

The PrismaRail unit attaches directly to the customer’s fiber-optic cable with a simplex SC/APC connector, which connects to a single fiber in the patch panel – ensuring access to a single fiber only, i.e., not compromising the activity or security of any other fibers in the cable. An Internet connection (LAN or WiFi) is required to transmit the monitored data to a C&C unit. 

 

Scaling up involves use of multiple PrismaRail units, each of which provides coverage for up to 100 km. Each unit is located in a communication room. All of the units combined require a single C&C unit in the customer’s operating center.

 

There is no need for discrete sensors. Upgrades are software based; no hardware upgrades are required.

Key Features & Benefits

Systems involving thousands of sensors along the railway are expensive for deployment, operation, and maintenance. The alternative is fiber sensing – using very long fibers as sensors – which is probably the most cost-effective solution. But before PrismaRail, existing solutions were ineffective due to high false alarm rates, poor target classification, and limited ability to use pre-deployed optical communication cables as "sensors".  

 

PrismaRail solves all of all these issues thanks to its revolutionary Hyper-Scan technology, which offers 100x sensitivity improvement over alternative systems.

PrismaRail has raw data of unparalleled quality. We apply Big Data techniques to data sets that are several orders of magnitude wider, with significantly higher SNR (signal-to-noise ratio) levels – leading to very high detection probability and advanced target classification. 

 

Upgrades to the system are software based and can be installed remotely.

All Information Consolidated in a Single Location & Single Display

The C&C unit presents the consolidated data of multiple units, with a real time map and detection table that displays the following information: 

  • Detection of events

  • Classification of events

  • Location of events at a high resolution

  • Identification of multiple, simultaneous events without interference or crosstalk
