module functions
The Trainnet® Juridical Recording Unit (JRU) is a train event recorder complying with the ERTMS/ETCS standard. Like any Trainnet® Event Recorder, it is an on-board data recorder for collecting, storing and retrieving vital train-borne information, including audio and video signals.
key features
The Trainnet® JRU can be used standalone or integrated to a Trainnet® train computer or gateway. The Trainnet® JRU is made of a Rugged Memory Module (RMM), a processor and a power supply (Trainnet® PSV and PIU) fitted in a standard 19” rack. Additional bus interfaces can be easily added to the rack for connectivity with for instance MVB and CAN, making the Trainnet® JRU extremely versatile. Trainnet® I/O modules can also be added to the rack and be processed directly by the JRU.
The Trainnet® JRU can record data from the ETCS (i.e. European Vital Computer, EVC) and/or from nation-specific control systems (i.e. Specific Transmission Module, STM). The ETCS architecture illustration highlights the two standard setup options. The Trainnet® JRU stores both analogue and digital signal data, for a predetermined period of time. The JRU can acquire data from its Ethernet port, its RS-485 port or from any added bus interfaces.
The JRU can record video streams. For easy data retrieval, the stream format can be made compatible with your CCTV Software or any other video analysis Software that you use. Alternatively, we can develop customized video analysis tools to fit your needs.
Data can be retrieved at any time via the Ethernet port or with a USB-stick. The Trainnet® TIP Software (Train Inspection Program) enables data analysis after an incident or as a regular procedure to optimize operations.
The Trainnet® Rugged Memory Module (RMM) ensures a high level of data protection. This crash-proof construction guarantees that the memory board is protected against fire, magnetic fields and any liquids, as well as against any mechanical stress during an impact or continued pressure.
