Implementation of a new communication system for reconfigurable mechatronic modules

This paper presents the analysis and implementation of a new communication system, which uses the DC link cable as a communication channel to reduce electrical interfaces and save cables. The channel characteristics are investigated to determine the carrier frequency and the bandwidth. To deal with the disturbance and signal fading, coded Orthogonal Frequency Division Multiplex (OFDM) is used as means of modulation/demodulation. A field test system is established. The test results show that it achieves a high performance with regard to the industrial standards.
