Internet Of Things And How It Interconnects The Worlds
Today, Internet of Things (IoT) technology is turning vehicles into the hub of an entire of connected services that offer users a variety of benefits, including enhanced safety and security, a richer user experience, and a new suite of product. The IoT (Internet of Things) represents a distributed network system of the real world devices and technologies as well as the interconnection of networks of physical devices across the Internet. IoT devices will be everywhere, context aware and will enable ambient intelligence (Andrew Whitmore, Anurag Agarwal and Li Xu 2015). This has added to the growth of new opportunities for the Information and Communication Technology (ICT) sector, by presenting a way to new services and applications will be able to leverage the interconnection of physical and virtual realms (Daniele Miorandi , Sabrina Sicari ….. and Imrich Chlamtac 2012).
The Internet of Things has changed the future of computing and communication with the idea of anytime, anywhere connectivity for anything. Even in the introductory stage of evolution, the Internet of Things has transformed the way corporations and consumers interact with each other and the surroundings. This innovation has led the embedding of electronics into everyday physical objects, and making them smart” such as Smart Wearable, Smart Cities, Smart Grid, Smart Parking and Smart Home.
Faults occur in vehicles or automobiles very often than not. This can be due to several reasons. Faults can range from simple to complex problems such as radiator leakage or overheating, tyre pressure problems etc. to gearbox problem, electrical, clutch, turbo, brakes, alternator, cylinder head gasket, air-conditioner condenser problems, etc. The ability to detect and isolate these faults in automobile is important in order to fulfil dependability requirements. Fault detection and isolation(FDI) in automobiles is very important because it helps to maintain high vehicle operational efficiency, low exhaust emissions, high vehicle uptime, fuel consumption reduction or fuel economy, high vehicle safety and it guarantees efficient repair. These factors are very important because they help to reduce overall life-cycle cost of a vehicle. Computer system can interface with other hardware devices such as Analog-to-digital Converter (ADC), sensors, etc, to detect and isolate faults but the software is very important so that the detected faults can be converted from analogue to digital format and be displayed as information. This information can also be conveyed digitally to a remote location and displayed in a readable format for vehicle owners via a web interface using IOT as a medium for communication. According to Carl Svärd (2012), complicated technical systems aimed at commercial use are often designed for low cost and high functionality, and not primarily to bring about fault detection and isolation (FDI). In particular, this means that there are few sensors and foremost a limited amount of hardware redundancy in the form of multiple sensors measuring the same quantity. To achieve good performance, and at the same time minimize the need for expensive redundant hardware, model-based fault detection and isolation (FDI) is often adopted. The hardware microcontroller for the project was modelled and a data logger was used in entering vehicle faults and location into the system.
