REDSEC: sistema de monitoramento e imobilização para automóveis

Abstract

Car acquisition, whether new or used, is increasingly common in contemporary societies, however, as a way of protecting the investment made, some care is needed. One of the risks that the owner can suffer is the theft / theft of the vehicle, the risk of having a total loss. The present work aims to develop a technological security solution (a prototype called REDSEC) for tracking cars, which sends the location of the vehicle to a broker server, being able, if necessary, also to immobilize the vehicle remotely. REDSEC was developed as an IoT (Internet of Things) solution that uses the MQTT protocol to communicate with the embedded system. Tests were carried out where a good average of latency values and zero packet loss were obtained, after the tests performed, demonstrating that the 2G cellular network meets the requirements to be the means of communication for the embedded system. It is expected that in the future the device will be improved, allowing that, in addition to the location and remote immobilization of the vehicle, it is able to monitor and send the vehicle fault codes to the server to serve as input to the preventive maintenance server.
