Design of Hardware Module for the Vehicle Condition Monitoring System Based on the Internet of Things

摘要

One problem in the development stage of driverless cars on public roads is how to monitor the condition of the vehicle that is affected by different weather and environment,including dry,snowy or heavy rain conditions,which are sometimes difficult to predict and require monitoring systems that should be real-time and accurate.For this reason,an internet of things-based car condition monitoring system is needed to be developed.The development covers three essential parts,which include the development of hardware and digital communication modules,web server development and data analysis and mobile application development for monitoring.The purpose of this study is to design a hardware module needed for car vehicle condition monitoring system;a prototype completed with the onboard diagnostic module and embedded system that will send data to the server in real time.The system was successfully designed and developed using ELM327 and ESP32 with SIM808 for communication module.The benefits of this research are as a tool for asset management of car vehicles both for personal and corporate needs.This study also supports the development of driverless cars that require real-time data input between the vehicle and the server.
