General Physical

The Internet of Things (IoT) is an information carrier based on network communication, and it can make all general physical objects which can be independently addressed from an interconnected network. Controller Area Network (CAN) is a kind of serial communication network which can effectively support distributed control or real-time control. This paper proposes the design of an IoT-oriented universal CAN bus. In order to build a complete CAN communication simulation model, message sending and message receiving models are constructed, respectively. The simulation experiment proves that the IoT-oriented network communication model designed in this paper not only has low power consumption, but it can also solve the front-end compatibility problems caused by different communication protocols.

<p>In this paper the Controller Area Network (CAN) Controller is presented. CAN is an advance serial bus communication protocol that efficiently supports distributed, broadcast real-time control and fault tolerance features for automobile industries to provide congestion free networking. The CAN Controller is designed for scheduling of messages, consist of the Transmitter Controller, FIFO buffer, CRC generator and bit stuffer. Scheduling messages on CAN corresponds to assigning identifiers (IDs) to message according to their priorities. Non Return to Zero (NRZ) coding and Non Destructive Bitwise Arbitration (NDBA) is used. The data is taken from the buffer FIFO, bit stuffed and then transmitted after CRC is performed. The whole design is captured entirely in VHDL language using bottom up design and verification methodology. The proposed controller was designed for applications needing high level data integrity and data rates upto 1Mbps. The applications of CAN are factory automation, machine control, automobile, avionics and aerospace, building automation.</p>

The Internet Of Things

Latency-sensitive applications for the Internet of Things (IoT) often require performance guarantees that contemporary wireless networks fail to offer. Application scenarios involving real-time control of industrial machinery, robotics, or delay-sensitive actuation therefore typically still rely on cables: today's wireless networks cannot deliver messages in a sufficiently small and predictable amount of time. Drop-in wireless replacements for these cabled systems would nevertheless provide great benefit by eliminating the high cost and complexity associated with running cables in harsh industrial environments [1]. The symbolsynchronous bus, introduced in this article and embodied in a platform called Zero-Wire, is a novel wireless networking paradigm that addresses this gap. Using concurrent optical transmissions, it strives to bring low-latency deterministic networking to the wireless IoT.

Performance Indexes

Controller Area Network (CAN) is widely used in automotive and industrial areas. To give guidance in the design process, CAN bus communication model is established using Matlab/SimulinkTM. Considering the error frames on the bus, the formula that calculating CAN response time and bus load is revised. The relating performance indexes of CAN bus is gained separately through calculation and simulation, it concludes that the CAN bus communication model can efficiently simulate the message transfer sequences in the real bus, and achieves an exact result of the performance analysis of the CAN bus system.
