Abstract

In this contemporary era, automobiles have become an integral part of one’s life. The repercussions of which demand automobiles with enhanced security systems in order to indemnify against lethal fiascos. The presented work thus cites a system predicated on Controller Area Network (CAN) protocol, a communication protocol which extends an efficient and real-time solution for the transfer of information amongst nodes, harnessed to preclude failures in vehicles and assist the driver by providing apposite indications and messages.The system is a three node network comprising of an 8-bit, Master Synchronous Serial Port (MSSP) module supporting 3-wire SPI (all 4 modes) slave controllers (PIC18F4550) which forms a data acquisition system and the CAN bus facilitates efficient transfer of this acquired data to the 32-bit, SPI compliant master controller (ARM7 LPC2148). In order to interface these controllers to the CAN bus, these controllers require external CAN controllers (MCP2515) and CAN transceivers (MCP2551). The main objective of fabricating such a system being interchangeability of node controllers keeping the CAN bus network unperturbed. Also, one of the major advantages of establishing CAN communication is that it is resilient to electrical noise.
基于CAN协议的智能车辆安全监控系统
在这个时代,汽车已经成为人们生活中不可或缺的一部分。其影响要求汽车具有增强的安全系统,以防止致命的惨败。因此,所提出的工作引用了一个基于控制器局域网(CAN)协议的系统,CAN协议是一种通信协议,它扩展了节点之间信息传输的高效实时解决方案,用于排除车辆故障,并通过提供适当的指示和信息来协助驾驶员。该系统是一个三节点网络,由一个8位主同步串行端口(MSSP)模块组成,支持3线SPI(所有4种模式)从控制器(PIC18F4550),形成一个数据采集系统,CAN总线有助于将采集的数据有效地传输到32位SPI兼容主控制器(ARM7 LPC2148)。为了将这些控制器连接到CAN总线,这些控制器需要外部CAN控制器(MCP2515)和CAN收发器(MCP2551)。制造这样一个系统的主要目标是节点控制器的互换性,保持CAN总线网络的不受干扰。此外,建立CAN通信的主要优点之一是它对电噪声具有弹性。
