The GOT710-837 Railway Touch Panel PC for Train Control
GOT710-837 Railway Touch Panel PC for Train Control

The railway sector is always the focus when it comes to public transportation improvement, and today’s train travel has become safer and more enjoyable thanks to a multitude of new technologies brought into the railway infrastructure. The implementation of touch panel PCs to facilitate train control and management presents an excellent example of this trend.

Panel PC – Desirable Railway Rolling Stock HMI

TCMSAn industrial panel PC is an all-in-one computer consisting of an LCD panel display with an embedded industrial computer built into the same enclosure, also commonly referred to as Human-Machine Interface (HMI). The HMI typically utilizes a touchscreen for ease of use and can be panel mounted, providing a graphics-based communication interface that allows interaction between humans and machines in an electronic control system. When deployed inside a modern locomotive cabin, the HMI is used as a Driver-Machine Interface (DMI) unit that assists or substitutes for traditional consoles on a control stand, through which the driver can operate and communicate with the entire train. The railway industry is increasingly favoring high-performance panel PCs as ideal HMIs for Train Control and Management System (TCMS) because of their usability, visualization and versatility.

Intuitive controls

With built-in touchscreen displays, panel PCs offer a remarkably intuitive and user-friendly onscreen interface that significantly simplifies complex train controls, allowing operators to manipulate a visualized console simply by tapping or touching the screen, rather than having to use a number of extraneous switches and knobs typical of conventional dashboards.

Visualized data

As screen resolutions and wide-screen formats continue to evolve, high-performance panel PCs can deliver a greater visual or graphical representation of train conditions and real-time data acquisition. Display of visualized information enables operators to grasp train conditions at a glance.

Computing power and storage capacity

Panel PCs can store data locally and deliver powerful computing performance to help manage complex tasks more easily.

Impeccable Train Control HMI – Axiomtek’s GOT710-837 Touch Panel PC

GOT710-837Axiomtek’s industry-leading GOT710-837 is a rugged 10.4" fanless touch panel computer built specifically to optimize train operation and user experience for railway transportation. It can be integrated as an HMI PC inside a locomotive cab to show vehicle status and execute control functions, or as a control panel for the passenger information system, covering applications across train communications, monitoring and controlling of speed and temperature, surveillance, as well as fleet information management. Designed to tackle the most challenging rolling stock tasks, this multifunctional, heavy-duty touch panel PC is capable of surviving some of the worst conditions seen in harsh outdoor operations, making it particularly suited for demanding railway work.

The GOT710-837 excels at the following aspects crucial to railway applications:

Railway EN50155-certified durability & reliability

The GOT710-837 panel PC is EN 50155 certified and has passed all safety-critical tests required for electronic equipment used on railway vehicles. Its ruggedized design, including an IP65 / NEMA 4 rated aluminum front bezel to keep out dust, liquid spillage and contaminants, makes it tough enough to withstand the severe conditions typical of the railway environment. The fanless structure and adoption of a low-power consumption Intel® Atom® processor allow it to operate in temperatures as low as -25°C and as high as 70°C. Certifications earned by the GOT710-837 also include EN 61373 (shock/vibration), EN 45545 (fire), as well as EN 50121-3-2 for Electromagnetic Compatibility (EMC) conformity, which ensures that different devices can operate in close proximity without experiencing mutual interference.

Anti-shock M12-type connectors

Keeping all I/O connections and power input firmly secure at all times is essential to any system installed on a jolting train. The GOT710-837’s IP65-rated M12-type I/O connectors are designed to protect its serial, USB, Gigabit LAN and DC power input connections against strong shock and vibration, making the panel PC a perfect HMI choice for on-train operation.

Sunlight readable LCD panel

The screen of a railway-use HMI computer needs to be bright enough to be comfortably viewed in full sunlight. To achieve optimum visibility, the GOT710-837 has a 10.4-inch ultra-bright, sunlight readable SVGA TFT LCD display, with LED backlight of 1,000-nit brightness and a wide 160°/160° viewing angle, allowing train operators to easily read any operational status messages – even in the glaring sun. The LCD panel also features a resistive touchscreen and is capable of auto-dimming by adjusting backlight brightness based on surrounding lighting conditions.

Alternative front-bezel keypad

HMI PCs installed in vertical panels or cabinets rely on touchscreen controls to navigate and interact. For some actions that aren’t quite intuitive or convenient on a touch screen, physical buttons still offer the best user experience. The GOT710-837’s IP65-rated front bezel can be customized to integrate a UIC612-01 standard keypad, which provides hotkeys and shortcuts for quick access to frequently used functions. Conforming to the UIC612-01 standard, the technical specifications of this front bezel keypad are universally defined via a friendly user interface, offering drivers a worldwide coherent HMI command across different types of locomotives.

Powerful computing – Intel® Atom® processor E3845 and more

The GOT710-837 adopts an Intel® Atom® processor E3845 (2M Cache, 1.91 GHz) built to handle multi-tasking applications, allowing it to deliver consistently reliable performance on railway work. The panel computer supports up to 8GB of onboard DDR3 memory and has 16GB of built-in flash storage. An mSATA slot is also available for additional storage needs.

Real-time monitoring & communication

The GOT710-837 makes real-time monitoring of train operation possible by providing instant access to sensor data. It shows mission-critical information about the train as well as alarms and faults, based on which operators are able to respond to an emergency quickly and perform a timely diagnosis to avoid danger or prevent equipment failure. Via Power over Ethernet (PoE), the panel computer can carry out remote surveillance by connecting to onboard IP cameras to display live video views from the inside and outside of a passenger cabin. Besides, wireless connectivity to cellular networks like 3G enables the GOT710-837 to communicate with monitoring centers to exchange data in real time.
