Rugged panel PCs are designed for interactive rail applications
Panel PCs from duagon break the company’s usual design pattern and are powered by an Intel Atom processor from the E3900 series. The DC19 and DC20 are intended for use in rugged railway applications.
The processor runs at up to 1.6GHz and equipped with up to 8Gbyte RAM with error code correction (ECC) and a 32Gbyte soldered eMMC. Standard interfaces for the DC19 and DC20 include two Gigabit Ethernet, one CAN, one audio, two digital I/O and RS232/RS422/RS485, which are all available on M12 connectors at the back of the panel PC. In addition, wireless communication functions such as 4G and GNSS and be controlled by two PCI Express Mini Card interfaces. Two micro-SIM card slots with dual-SIM functionality are accessible at the back of the panel.
The maintenance-free human-machine interfaces (HMIs) operate in a -25 to +70 degrees C environment and can be tailored for different applications in various train models, says duagon.
The typical railway environment is defined by harsh conditions and narrow spaces. Computers must therefore be robust and impact resistant. This also applies to multi-functional displays in the driver cabin, whether in lightweight rail, high speed or freight trains. The DC19 and DC20 can be integrated into the train control and management system (TCMS) or be used as an HMI for driver information about the route. They can also be used as camera displays in security or monitoring systems.
Both the 21.1-inch DC20 and the 10.4-inch DC19 house have a robust impact resistant XGA TFT LCD touchscreen display with LED backlighting. To accommodate the limited space available, the DC19 and DC20 have a small, flat mechanical design and a choice of configuration options. The housing is rugged with an IP65-compliant front. It supports a railway-compliant power supply of 24 to 110V DC and has an internal power supply which complies with EN 50155 class S2. All electronic components are soldered to withstand shock and vibration, backed up by solid M12 connectors, and protected by conformal coating. According to the standard, both panel PCs operate in a -25 to +70 degrees C environment (+85 degrees C for 10 minutes), which is achieved through fanless conduction-cooling.
