CAN-to-GPRS gateway with recording capability

Peak-System (Germany) offers the PCAN-GPRS Link module for recording and forwarding vehicle data. Two incorporated high-speed CAN channels (ISO 11898-2) support bit-rates of 40 kbit/s to 1 Mbit/s.

HANDLING OF OBD-2 DATA IS DONE VIA THE CANNETWORK. On request, the CiA 447 CANopen application profile for special-purpose car add-on devices and the J1939 protocol support may be provided. The dual-core (ARM7 and ARM9) system records the data to internal flash memory of up to 32 GiB. Two incorporated programmable micro-controllers process internal vehicle data. Two digital inputs and one digital output as well as an UART interface are offered. The device with operating voltage from 6 VDC to 32 VDC may work at temperatures from -40 °C to +85 °C.
The module is provided as a development platform for telematic applications. An API (application programming interface) allows integration in a specific application environment. The device supports evaluation of FMS (fleet management system) and Bus FMS data. This produces consumption-related vehicle data. The DTCO interface allows the connection and processing of a digital tachograph data with access to such information as driver identification and driver working time. The built-in U-blox 5 GPS module has 50 channels and over 1 million correlators. It may be used to determine location and output the direction of travel. The device functions may be expanded to allow additional data to be processed, output and recorded. These include temperature and movement sensors, barcode scanners, RFID readers, displays, and WiFi or Bluetooth connections.

The module with the E1 type approval is supplied with a programming example in the form of a Linux Daemon for x86 Debian. The Daemon tool receives the data from the module and writes them to a Mysql database. Data can then be visualized using a PHP script based on Google Maps and Ajax. Output includes the FMS and OBD-2 data and positions of all modules connected to the database. Firmware update via GPRS is possible.
