Abstract:

This project aims in designing a system which helps in monitoring and controlling multi-regions using CAN (Controller Area Network) protocol. This system helps in achieving communication between multiple devices. The main objective of this project is to provide CAN communication based vehicle security for automobiles, this system also avoid rear end collision using sensors and wireless communication. The CAN protocol for serial data communication. The protocol was developed aiming at automotive applications. Today CAN has gained widespread use and is used in industrial automation as well as in automotives and mobile machines. The CAN protocol is implemented in silicon. This makes it possible to combine the error handling and fault confinement facilities of CAN with a high transmission speed. The method used for distributing messages to the right receivers contributes to gaining a good use of the available bandwidth. This requires a simple transmission medium. A common transmission medium is a twisted pair of wires. A CAN system can also work with just one wire. In some applications different kinds of links, optical links or radio links, are better suited. Though there is transmission hardware standard (twisted pair), it is not uncommon to use different transmission solutions depending on system requirements. Obstacle sensor capable of detecting of Objects, Alcohol sensor to detect alcohol percentage, Buzzer to give alerts, CAN transceiver is to establish communication between two microcontrollers, LCD to display the parameters. This system makes use of two Microcontrollers which are connected using a CAN bus. One of the Microcontrollers has Fire sensor, Obstacle sensor, Alcohol sensor, LCD and Buzzer are interfaced to it. This controller gets input from these sensors and continuously monitors them. The controller automatically monitors, if these inputs go beyond threshold level and also alerts through buzzer. These parameters are transferred over CAN bus which is received by the other controller connected to it. This controller makes the parameters to display on LCD connected to it. Also, alerts at this system if parameters go beyond threshold level. The Microcontrollers used in this project are programmed using Embedded C programming.
