Protótipo para coleta de informações da rede CAN em automóveis

Abstract

Within the vehicle fleet market, managers have increasingly recognized the importance of effective fleet management and its impact on their company's results. Vehicle fleet management is based on the control and analysis of information generated by vehicles during use and on the behavior of drivers in their operation. To access this data, there are several devices and services available on the market for collecting information and pointing out failures. Complex hardware devices are found for professional use in automotive mechanics, to supervisory services and smartphone applications for companies with vehicle fleets. Within this context, this work presents the development of a system for collecting information about the automobile and making available online of the data. The main objective of this work is to detect adverse events during driving, reading the information available in the vehicle data communication network, such as speed, RPM and engine temperature. Based on the bibliography, a prototype capable of accessing this information via the vehicle's OBDII port was developed, by sending packages containing the PID codes of interest. Upon receiving the response, it checks whether the value is within the range defined as the limit for that parameter. If the value exceeds the limit, it is recorded in a text file. Through the Wi-Fi connection, the data present in the text file is published in a online spreadsheet. Finally, using Google Data Studio, data is visualized in the form of dashboard. To validate the prototype, a comparison was made with the results obtained using commercial tools with similar proposals. The prototype proved to be effective in collecting and publishing vehicle information compared to applications for smartphone, demonstrating to be able to obtain the same level of information from this type of solution. Comparing the dashboard developed with commercial solutions already known in the market, the solution proposed in this work, as a free tool, proved to be capable of providing information similar to that obtained using these consolidated services.
