Design and Implementation of Airborne CAN Bus Test Repeater

This article first introduces the specifications of CAN bus and proposes a new CAN bus testing scheme for applications in airborne environments. This scheme utilizes existing equipment to collect CAN bus data using repeaters and CBM/101 acquisition boards. The following mainly elaborates on the role of relays, and introduces the software and hardware design of relays. The design and implementation of relays are important components of CAN bus testing solutions.
