1 STEVAL-IEGV Smart vehicle tracking system Data brief Features Real-time vehicle tracking system based on GPRS/GSM/GNSS. The vehicle location coordinates are acquired using FASTRAX GPS/GLONASS module and sent over GPRS to the web server-based fleet tracking application Web GUI-based application based on API s provided by third party map provider Open Street Maps can monitor up to vehicles, their known location and status Car lift alarm for anti-theft feature ( MEMSbased) Black box functionality: in case of vehicle crash (detected using MEMS), vehicle status and location parameters are stored in the micro SD card and SMS. In all other cases any alarm notification is through web-based GUI Tamper and panic detection, and alarm Local graphic display of information such as vehicle status, location coordinates, speed, distance covered, GPS strength, GSM signal strength, time and date Ability to send alert message from web application to be show on tracking system display Buzzer on vehicle unit for alarm indication On-board user switch for different actions RoHS compliant Description The STEVAL-IEGV is a smart vehicle tracking system reference design based on GPS- GLONASS/GSM-GPRS. The system is built around the Cortex-M STMFx microcontroller series. Today, tracking and navigation systems for vehicles are extensively used all over the world by public transportation units, fleet owners and individuals, and are essential parts of vehicle telematics systems. The design consists of a vehicle unit (to be installed inside the vehicle) and remote web server application where the vehicle status and movement information may be viewed in an intuitive way on the map. The vehicle unit is built around the Cortex-M STMFx microcontroller, Fastrax GNSS (TESEO II) module and a SAGEM GSM/GPRS module. The vehicle unit gathers the GPS/GLONASS information on geographic coordinates, time, date, speed, in-journey distance traveled and satellites fixed, and sends this information over GPRS to the web server application. The web application shows the current location and status information of the vehicle on open street maps. The same information is displayed locally on the graphical LCD display. This unit also consists of MEMS sensors LISDLH -axis accelerometer, and LGD yaw/pitch/roll gyroscope. This unit also serves as a theft detection unit and senses car lift using MEMS. In case of vehicle crash (detected using MEMS), the vehicle status and location parameters are logged in the micro SD card, and the same information is sent to the administrator over SMS, thereby providing blackbox functionality.
