Vehicle Computer With SAE J1939 Interface For Utility Vehicles, Agricultural And Construction Machines
Posted by on
Syslogic has announced their VSL Compact 81 vehicle computer as part of 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.
CAN Logger 1000
The CANLogger1000 offers simple and user-friendly logging of data from a CAN-Bus without the use of a computer. Data are stored on a standard SD-card in a simple format such that it can be directly loaded into an analysis tool for further post processing. The logged data can be transferred to a PC using a standard mini-USB cable and requires no special software.
For advanced users, the device offers a wide range of configuration possibilities, such as message filtering, down-sampling, automatic bit-rate detection, cyclic-logging, heartbeat signal and runtime logging control. Further, recently added features include the ability to transmit up to 20 custom CAN messages (for use in e.g. OBD-II logging) and a new serial interface letting the logger act as a CAN interface for streaming real-time data (incl. integration with Wireshark via CANvas).
