Modern vehicles have complex electronic system with number of electronic control
units (ECUs). The functionality of these ECUs are monitored by logging the data
obtained from these ECUs. Recording and storing large amount of data is not
an efficient way, often it is not possible because of limited hardware and software
resources. Also, the analysis of large amount of data can take a considerable time
and effort.
This thesis put forward the design of a WLAN based generic vehicle data
logger for quick integration into the vehicle system. The main goal of the thesis
is to develop a WLAN based generic vehicle data logger for a vehicle, which can
filter only useful data and also
exibility of changing the parameters of the data
logger. Since, most existing data loggers are application specific nature and lack of
data filtering and processing capabilities. WLAN based generic vehicle data logger
is developed to overcome these problems.
The software which is developed, runs on a STM32 evaluation board and
WLAN module. CAN bus transfers the real data from vehicle. ST Microelectronics
provides a wide range of connectivity modules and basic software packages to
enhance the speed of development. By choosing a suitable WLAN module with
inbuilt TCP/IP stack it is possible to upload the useful data onto the server over
internet. TCP/IP also provides many application level protocols like HTTP, TFTP,
FTP, SMTP thereby it's possible to compare the different protocols for speed and
reliability.
In this thesis work, Chapter 2 presents the state of the art, a study of
different data loggers, analysis of available options, comparison and the justification
for designing WLAN based generic vehicle data logger. Chapter 3 represents the
concept and study of desired specifications of the WLAN based generic vehicle data
logger and also choosing the suitable hardware platform for it. Chapter 4 explains
hardware development and integration of different modules with hardware platform.
Software implementation of thesis design is presented in chapter 4 and results are
discussed in chapter 5. Conclusion and future work is in chapter 6.
