An API allows simple integration of functions within a specific application environment. The PCAN-GPRS Link supports the evaluation of FMS and Bus FMS data (Fleet Management System) for which it produces consumption related vehicle data. There are two programmable microcontrollers within the unit which process internal vehicle data and run the GPRS. The DTCO info interface also allows the connection and processing of a digital tacho with access to information such as driver identification and driver working time. The U-blox 5 GPS module with its 50 channels and over 1 million correlators, yields a position accuracy of 2.5m.
There is an optional expansion 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 unit is supplied with a programming example in the form of a Linux daemon for x86 Debian. This daemon receives the data from the PCAN-GPRS Link 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.
