Embedded World 2018
Syslogic has added the VSL Compact 81 vehicle computer to its mobile computing range. The computers are used in trains, busses, and even automated guided vehicles (AGVs) in construction as well as agricultural machinery.
All electronic components are firmly soldered in the vehicle computer, which also has no moving parts. Instead of rotating memory, industrial flash memory is used, requiring no fault-prone fan thanks to the passive cooling concept. Threaded M12 connectors were used for the LAN interfaces and the power supply. All in all, this design makes sure the vehicle computer continues to function for the long term, even under the toughest of conditions. When it comes to shock and vibration, the device is compliant with EN 61373. As for EMC (electromagnetic compatibility) and electrical isolation requirements, the computer meets EN 55022, EN 55024, EN 61000-6-2, and EN 61000-6-4.
Another key criterion in vehicle computers is the temperature range. Be it trains, diggers, or even tunneling machines – vehicles are often subjected to extreme thermal loads. In the vehicle computer, all components are designed for an operating temperature range from -40 °C to +85 °C.
In addition, the vehicle computer is equipped with an ignition controller and a disturbance-free CAN interface. For CAN interface support, well-known CAN drivers such as SocketCAN, LinCAN, or higher-layer protocols such as J1939 and CANopen are pre-installed. Yet another feature enables activation of CAN read-only (passive CAN), which is frequently used in data loggers.
The vehicle computer shown at the Embedded World 2018 is suitable as a data logger, control computer, data-capturing unit, or vehicle-to-vehicle or vehicle-to-infrastructure communication system. With its quad-core processes from Intel Atom’s Apollo Lake series (x5-E3940 or x7-3950), power reserves are ready for action in demanding applications. Thanks to on-board wireless modules (LTE, UMTS, GPS, WiFi), the vehicle computer is also capable of acting as an IoT gateway. With its interface layout, the product can be integrated into various vehicles and supports a number of bus systems such as CAN. The control computer can be equipped with wireless technologies such as LTE, GPS, and WiFi using expansion cards developed by Syslogic, making it suitable of IoT applications. To simplify the integration of wireless modules, the company provides pre-installed operating systems, such as Windows 10 and Debian 9, which contain pre-installed drivers, enabling commissioning.
