A recent spike in railway terrorist attacks has prompted rail operators to bolster their railway surveillance and real-time monitoring efforts to keep passengers safe. An embedded computer lies at the heart of a reliable Network Video Recorder (NVR) system, gathering video inputs from multiple IP cameras in the passenger compartments. The NVR can then identify conflicts, crowding, running, and unattended baggage, and issue warnings for abnormalities. An Asian railway system integrator used the Cincoze high-performance and power-saving embedded computer DI-1000 in the NVR system to conduct in-carriage real-time monitoring, so the driver and traffic control center can react swiftly and take necessary actions to ensure the safety of railway operations.

Powerful and Small Footprint

Real-time video monitoring for smart railway surveillance requires a high-performance industrial computer to handle recording, playback, and backup, perform video analysis, and issue warnings for abnormalities. Since the space inside the train is limited, the size needs to be small and compact so that it does not take up too much space.

Rail-specific Interfaces

Rugged I/O interfaces, such as M12 LAN are a requirement to handle the continuous vibration on trains. An IGN function is also necessary for delayed power on and off to avoid sudden shutdowns and loss of video data. Mini PCIe supports GNSS/GSM for train positioning or data transmission, and the DisplayPort interface displays the video analysis results on the monitor in the train control room.

Rugged and Rail-certified

Trains must withstand varied weather conditions while traveling across the country. Extreme changes in temperature and humidity caused by rain, snow, and ice are common. Coupled with the continuous vibration and bumps caused by acceleration and deceleration, as well as the EMC interference caused by other electronic equipment around the installation environment, a rugged industrial computer that has passed rail certification is needed to ensure that the train runs safely, reliably, and stably.

High-performance and Compact

The Cincoze DI-1000 embedded computer is a high-performance and compact embedded computer that can be equipped with a 6th Gen Intel® Core™ processor with Intel® HD graphics and supports up to 32GB of DDR4 2133MHz memory so that the DI-1000 can meet various high-level computing requirements. It can also perform real-time analysis on a large amount of video data in the NVR system. The front maintenance area has a hot-swappable 2.5-inch SATA HDD/SSD slot, allowing quick access to data in the event of an emergency. The overall size is smaller than a sheet of A5 paper, making it easy to install in any space.

Industrial I/O and Flexible Expansion

The Cincoze DI-1000 compact design doesn’t sacrifice I/O or functionality. The DI-1000 includes 2× 1GbE LAN, 4× USB 3.2, 2× USB 2.0, and 6× RS-232/422/485. DI-1000 also supports two full-size Mini PCIe and one SIM card slot for GNSS/GSM positioning and mobile communications to ensure uninterrupted data transmission. Through Cincoze’s proprietary CMI and CFM modules, I/O or functions can be flexibly added according to needs, such as LAN and M12 LAN interfaces and IGN (Power ignition sensing).

Rugged Design and International Certification

The DI-1000 continues Cincoze’s rugged DNA, with a cableless, jumperless, fanless design and withstands high shock and vibration (5/50 Grms) which reduces the risks in train operation. In addition to the risks caused by vibrations, it also provides a series of industrial-grade protections, such as wide voltage (9 to 48VDC), and wide operating temperature (-40°C to 70°C), to ensure that the train can tolerate severe weather changes and voltage fluctuations for stable operation. The railway computing EN 50155 (EN 50121-3-2 only) specification certifies that it can prevent EMC interference between various electronics and electrical equipment in the train, ensuring the safety and stability of the railway system.

For advanced applications, the new DI-1100 is also available, which is equipped with the 8th Gen Intel® Core™ U-series processor with up to four -cores performance and supported up to 32GB of DDR4 2400MHz SO-DIMM memory to meet the power requirements of graphics processing and high-speed image conversion. In addition to passing the EN 50155 (EN 50121-3-2 only) EMC requirements that railway computers should have, it also passes the US military equipment inspection standard (MIL-STD-810G) and can withstand long-term railway computing environments with strong vibrations.
