Development of gateway based on BroadR-reach for application in automation network

Abstract

Research to improve the performance of in-vehicle network systems has been conducted as a result of the gradual increase in the number of automotive applications that require a large amount of data (e.g., Advanced Driver Assistance System (ADAS), Infotainment, connected car, etc.). BroadR-Reach is a technique that is used to improve the performance of in-vehicle networks by enabling Ethernet communication over single pair of Unshielded Twisted Pair (UTP) wires. Ethernet provides much faster transfer rates and a larger payload than existing protocols such as Controller Area Network (CAN), Local Interconnect Network (LIN), and FlexRay. Therefore, BroadR-Reach has been determined to be a future technique for applications such as ADAS. As in the aforementioned automotive applications, in automation applications, Real-Time Ethernet (RTE) is gaining widespread use because it is based on Ethernet. RTE provides improved performance over existing fieldbus for applications in automation networks, such as for highways, city surveillance, power substation, factory automation. This paper therefore describes the benefits of the BroadR-Reach for use in automation and also describes the development of a gateway between the RTE and RS-485 system. In addition, a method to validate the feasibility of a gateway based on BroadR-Reach has been introduced by comparing the performance of the gateway based on standard Ethernet.
