Time analysis of wireless controller area network-based fire and gas safety system

Abstract

Fire and gas safety (FGS) system are important tools for safeguarding process plants and production facilities that handle flammable and toxic materials. In general, a conventional fire and gas system has several shortcomings, such as weakness to noise and false alarms. In order to overcome these shortcomings, controller area network (CAN)-based FGS system has been implemented in our previous work. Further, considering that FGS systems are employed in hazardous environments, where wireless implementation of CAN is desirous, an attempt to make CAN wireless is carried out for these systems in this work, by using the radio protocol IEEE 802.15.4 to communicate CAN messages wireless. This work is a continuation of our previous work. Here the wired CAN interface is converted to wireless CAN and response time analysis of the system is done using CANoe v7.6.

Adaptive Fault-Tolerant System and Optimal Power Allocation for Smart Vehicles in Smart Cities Using Controller Area Network

“…e CAN protocol provides a serial bus communication for a reliable and robust platform to transmit and receives a message from one sensor node to another [7,8]. Using the CAN bus also provides a backbone for managing smart or automotive vehicle system engine control units (ECUs), brakes, and other components [9]. is CAN protocol is also used to improve the performance through distributed control and monitoring the congestion by virtue of sending priority messages from the various units of the vehicle [9,10].…”

In this system, a carrier sense multiple access/ collision detection (CSMA/CD) protocol and priority message scheduling are implemented to control overall communication, thereby reducing the cause of delays [11].…”
