Operating/storage temperature range is -40°C to +70°C, 10min at 85°C/ EN50155 Class OT4 depending on configuration -40°C to +85°C.

DESIGNED FOR MULTI-USE
A lot of overlap exists between applications using rugged embedded PCs. As a consequence, sometimes a product designed for general use is appropriate for transportation applications. An example is the Karbon 410 from OnLogic. Powered by a dual-core Intel Atom x6211E, or Quad-Core x6425E processor, Karbon 410 offers a unique combination of features, power and connectivity (Figure 5). The integrated Intel Programmable Services Engine (Intel PSE) enables support for a host of connectivity and power management functions, including CAN bus and automotive power control for in-vehicle applications. All of this makes Karbon 410 well suited as a rugged Industrial IoT gateway, edge device or embedded controller.

FIGURE 5 – The Karbon 410 is powered by a dual-core Intel Atom x6211E, or Quad-Core x6425E processor. The integrated Intel Programmable Services Engine (Intel PSE) enables support for a host of connectivity and power management functions, including CAN bus and automotive power control for in-vehicle applications.

Measuring just over 2″ tall, and with support for Wall, DIN Rail or VESA mounting, the Karbon 410 was designed to be installed anywhere you need ultra-reliable computing power. Sensitive internal components are protected from dust, debris, chemicals, and moisture with OnLogic’s integrated Hardshell Fanless Technology. Its rugged design, -40°C to 70°C operating temperature range, 9V-48V power input, and the absence of any moving parts dramatically improve the lifespan and reliability of the system.

The Karbon 410’s modularity and tiny footprint make it perfect for even the most inhospitable Industrial IoT or Industry 4.0 environments. Environmental testing is in process for Medical EMC (60601-1), Rail EMC (50121), Maritime EMC (60945), Automotive E-mark, as well as IEC and MIL-STD-810 shock and vibration. All of this performance is safely delivered inside a system NRTL listed to UL/IEC 62368-1, accompanied by a CB scheme.

Standard I/O includes two USB 3.2 and two USB 2.0 ports, dual LAN (with optional PoE), CAN bus (via 3-pin terminal block) and a DisplayPort. Onboard automotive ignition control allows you to program the on/off state of the system based on the power state of a vehicle, and the system’s integrated SIM slot and optional WiFi and 4G LTE give you wireless access to your critical data from anywhere. In addition, you can leverage OnLogic’s unique ModBay expansion capabilities to add dual COM or GPIO.

GPUs FOR TRANSPORTATION

The compute power of GPUs (graphics processing units) is yet another embedded technology that transportation system developers are anxious to leverage. Serving such needs, in March Cincoze launched the GP-3000, what is calls its flagship model system for AI and machine vision applications (Figure 6). It marries high-end computing performance, rich high-speed I/O, and harsh environment resilience to enable edge computing in the AIoT framework. It is designed for implementing multiple applications on the field side, such as smart manufacturing and transportation.

FIGURE 6 – The GP-3000 supports an Intel Xeon/Core processor and sports the Intel C246 chipset, with up to two sets of DDR4-2666 ECC/non-ECC SO-DIMMs for a maximum of 64GB of total memory. The high-speed I/O ports, with the simple addition of a camera, become the machine equipment’s eyes, allowing for the quick and accurate inspection and categorization of high-definition image inputs.

This setup provides a combination of efficient processing and parallel processing. The GPU Expansion Box (GEB) supports up to two 250W high-end full-length (less than 328mm) GPU cards to further enhance its processing capabilities. The high-speed I/O ports, with the simple addition of a camera, become the machine equipment’s eyes, allowing for the quick and accurate inspection and categorization of high-definition image inputs.

Ensuring passenger safety is always the primary criterion of transportation, and AI-enhanced systems can provide advanced monitoring of drivers, vehicles, and tracks. The Cincoze GP-3000 has powerful image processing capabilities and a high-performance CPU, which can quickly detect and analyze images to increase station safety monitoring, detect driver fatigue and monitor road and track conditions. In addition, the GP-3000 supports desktop, face-up, wall and rack mounting, to be installed in various car bodies or road application environments such as autonomous vehicles, in-vehicle supervision, remote signal monitoring, railway track monitoring and railway bogie condition monitoring.

The IGN module (power ignition sensing) can monitor the on-board battery voltage and set a delayed shutdown time to avoid damage to the system due to unstable current or instantaneous flameout when the vehicle starts. In the face of severe shaking and vibrations associated with the car body running or stopping, the “adjustable 3D GPU mount” exclusively designed for the GP-3000 keeps the GPU card firmly in place, even when shaken.

Three international certifications—the US military equipment inspection standard (MIL-STD-810G), E-mark and EN 50155 (EN 50121-3-2 only)—demonstrate the high stability and resilience of the GP-3000. The GP-3000 uses all industrial-grade parts to defend against harsh environments, boasting an operating temperature range from -40°C to 70°C. It features multiple protection systems such as overvoltage (OVP), overcurrent (OCP) and power reverse protection.

VEHICLE INFOTAINMENT

A key element of today’s transportation systems is infotainment. Mass transit systems have particularly demanding infotainment needs. Serving such demands, in April Sintrones unveiled its VBOX-3611-4L-D5G in-vehicle computer. The company says it is the first in-vehicle fanless computer with dual 5G network capability and dual SIM Card support (Figure 7). System developers can apply it to a mobile video, a network server with dual 5G aggregated network or a redundant network for the mass transit infotainment market.
