| dc.description.abstract | The objective of this work is to explore Internet of Things (IoT) concepts, applicability and its
main protocols, in the process of extraction and publication of data originated from modern
vehicle on-board diagnose systems. A bibliographic review about the subject is presented, ex ploring themes related to the modern car, combustion engine and its characteristics, control units,
communication and protocols. Other themes related to IoT, its characterization and definition,
main communication protocols and usage are also explored. There is a limitation in relation to
the user location in order to have access to a vehicle diagnostic information. With this problem
in mind, the work is proposing a system that acts as a gateway to connect vehicles to a central
system capable of giving the user a monitoring experience. The gateway system is responsible
for translating the messages in the OBDII (On-Board Diagnostic II) format to a MQTT (Message
Queuing Telemetry Transport) protocol format and publish it in the Internet. Tests with real
vehicles were made with the intent of ensuring compatibility, viability and performance of the
proposed system while collecting measurements of message processing time. This tests, after
the data was analysed, confirmed that the proposed system has a correct operation, processing
99.06% of the messages in 800 milliseconds. | pt_BR |
