Rugged Computing Solutions For The Transportation

Rugged environment

Electronic devices used in transportation are installed in vehicles, control stations or mobile units. These environments expose equipment to wide temperature variations, frequent vibration and shock.

Dust, moisture and electromagnetic interference also place significant demands on the ruggedness of the box PC or panel PC.

Power Supply

Voltage fluctuations and temporary power outages mean that electronic devices need a stable power supply and often redundant solutions to process data without interruption.

Rugged computing solutions support a wide input voltage range of 9–48 V DC to ensure stable operation. Vehicle supply voltages are typically 12–24 V DC

Ignition Sensing

In addition to voltage fluctuations and sudden voltage changes, the potential damage caused by an abrupt shutdown must also be considered. 

To address this, rugged vehicle computers are often equipped with ignition sensing, also known as an IGN module. This monitors the battery voltage and prevents the computer from starting until the voltage has stabilized. IGN can also delay shutdown to prevent system damage or data corruption if the ignition is switched off abruptly.

Correct Certification

The EU has a wide range of regulations designed to ensure that consumer products and materials are safe and fit for purpose. Passenger cars, trucks, buses and agricultural machinery are among the most strictly regulated product categories.

These products are assessed against requirements tailored to their specific risks and the environmental implications of their use. Once approved, they carry an E-mark rather than the CE marking used for other manufactured products.
