The Canadian company Sierra Wireless from the beginning of its activity in 1997 deals with the production of communication devices and modules for M2M and telematics applications, including gps / GenX (GNX) series GPS / GLONASS locator gates designed for AVL fleet tracking applications. Gateways (GenX GNX-6) by connecting to the GPS / GNSS application server through the GSM network (GPRS / EDGE / HSPA), thanks to, among others, a built-in three-axis accelerometer they send a number of data, including current vehicle location, acceleration, braking (including sudden in the event of an accident), speeds and a wide range of data collected via RS232, 1-Wire, J1708, CAN interfaces such as temperature, fuel level and consumption, revolutions, load or tachograph data as well as such information regarding vehicle safety as e.g. opening doors and covers, closing and opening the vehicle by remote control or starting the vehicle alarm system. Modern GNX-6 telematics gates also have a Bluetooth 4.0 interface in the Low Energy version, and thanks to the OTA (Over the Air) upgrade and management, they minimize the costs associated with having to return the vehicle to carry out the necessary upgrade of the AVL system.
On the other hand, thanks to the 1-Wire interface support, Sierra Wireless GNX-6 GPS gateway can cooperate with Netronix PLA RFID readers, supporting additional functionality related to driver identification, which can be done via RFID cards and transponders working in MIFARE® standards Classic (13.65MHz) or Unique / HITAG2 (125kHz).
This is extremely important information for every fleet system manager in medium and large enterprises, enabling cost optimization and control of fuel expenses, inspections, staff costs and many more. Driver identification allows for automatic assignment of employees to the vehicle in use, and thanks to RFID technology we can collect data such as:
- working time of drivers - e.g. traders,
- time of using a given vehicle, divided into business and private work time,
- number of kilometers driven per driver,
- and additionally, RFID is a protection against unauthorized use of the vehicle - without a suitable tablet or proximity card, the ignition will not be unlocked.
