Résumé
Since first introduced by Robert Bosch GmbH in 1980s, the Controller Area Network (CAN) bus showed good success and capability of working reliably, even in harsh environments. Multiple other sectors were seduced by the CAN-bus achieved role and importance in automotive industry. For instance in avionics, Airbus first introduced it on the A318 and A340 for cabin ventilation system control [1], and this usage keeps on increasing, specially with the focus on reducing the harness mass and complexity. For the same purpose, the interest to employ Power Line Communication (PLC) technology for airborne application is gaining ground in the frame of the More Electric Aircraft (MEA) or even an All-Electric Aircraft (AEA) architectures. Combining both technologies can reach a higher impact on reducing the cabling weight, complexity and space allocation. This paper explores a real-case context feasibility to implement CAN-bus protocol along with PLC technology over aircraft dc power line, with respect to CAN-bus aspects, PLC principals and aeronautic standard compliance. Comprehensive CAN-PLC tests and assessment were carried out, analysing latency, Bit-Error Rate (BER) and Electromagnetic Compatibility (EMC) in alignment with the RTCA DO-160G standard requirements.
