Abstract:
This paper describes the work that has been done
in the design and development of a wireless on-board diagnostic
system (OBD II) fleet management system. The system aims to
measure speed, distance, and fuel consumption of vehicles for
tracking and analysis purposes. An OBD II reader is designed to
measure speed and mass air flow, from which the distance and
fuel consumption are also computed. This data is then transmitted
via WiFi to a remote server. The system also implements
global positioning system tracking to determine the location of
the vehicle. A database management system is implemented at
the remote server for the storage and management of transmitted
data and a graphical user interface is developed for analysing
the transmitted data. Various qualification tests are conducted to
verify the functionality of the system. The results demonstrate
that the system is capable of reading the various parameters,
and can successfully process, transmit, and display the readings.
