On-board Unit and its Possibilities of Communications on Safety and Security Principles
Abstract
The technical solution of on-board unit (OBU) for vehicles used for dangerous good transport and design of vehicle sensor network (based on CAN bus) for dangerous good monitoring will be discussed. In presentation the conception of GSM/GPRS networking subsystem for real time data transmission into monitoring centre will be described. Next themes of discussion will be focused on the possibilities of solution of safety-related communication channel for safety sensor network in accordance with standard for functional safety of Electrical / Electronic / Programmable Electronic (E/E/PE) systems IEC 61508, recommended methods of risk analysis and possibilities of their modelling and proposal of secure communication channel over GSM/GPRS for secure data transmission into control centre on the base of IPsec protocol.
