“…To do so, the choice of the injected signals must be judicious to avoid the frequency bands used by the target system and called prohibited bandwidth. In the literature, several methods have been proposed to resolve interference problems such as Sequence Time Domain Reflectometry (STDR) [4], Spread Spectrum Time Domain Reflectometry (SSTDR) [5], Noise Domain Reflectometry (Noise Domain Reflecometry) [6], and Multi-Carrier Time Domain Reflecometry (MCTDR) [7]. Recently, a new method called Orthogonal Multi-tone Time Domain Reflecometry (OMTDR) has been proposed [8].…”

From reflectometry methods, this work aims at locating accurately electrical faults in complex wiring networks. Increasing demand for online diagnosis has imposed serious challenges on interference mitigation. In particular, diagnosis has to be carried out while the target system is operating. The interference becomes more even critical in the case of complex networks where distributed sensors inject their signals simultaneously. The objective of this paper is to develop a new embedded diagnosis strategy in complex wired networks that would resolve interference problems and eliminate ambiguities related to fault location. To do so, OMTDR (Orthogonal Multi-tone Time Domain Reflectometry) method is used. For better coverage of the network, communication between sensors is integrated using the transmitted part of the OMTDR signal. It enables data control and transmission for fusion to facilitate fault location. In order to overcome degradation of diagnosis reliability and communication quality, we propose a new sensor clustering strategy based on network topology in terms of distance and number of junctions. Based on CAN bus network, we prove that data fusion using sensor clustering strategy permits to improve the diagnosis performance.

“…Although SSTDR is considered as an interesting method for on-line diagnosis, it is still limited since it does not control the network bandwidth. This problem is well solved by Multi-Carrier Reflectometry (MCR) [13] and Multi-Carrier Time Domain Reflectometry (MCTDR) [6]. They employ a summation of harmonically related sine waves using Inverse Digital Fourier Transform (IDFT).…”

“…However, the presence of useful signals of the target system could affect the test signals due to interference, coupling and limited bandwidth constraints. Several reflectometry methods have been proposed to improve on-line diagnosis such as Spread Spectrum Time Domain Reflectometry (SSTDR) [4] methods, Multi-Carrier Reflectometry (MCR) [5] and Multi-Carrier Time Domain Reflectometry (MCTDR) [6]. These methods are interesting but remain limited as they require a huge post-processing procedure to reduce interference constraints.…”

Currently, on-line wire diagnosis using reflectometry is under intensive investigation, aiming at detecting and locating faults on wiring networks while the target system is operating. The idea is to inject a broadband test signal in the network under test and analyse the signal reflected by each impedance discontinuity. However, the presence of native signals on live wires may impact the diagnosis due to interference and EMC or limited bandwidth constraints. Our proposed "Orthogonal MultiTone Time Domain Reflectometry"(OMTDR) method, based on Orthogonal Frequency Division Multiplexing (OFDM) technique, seems to be a suitable candidate for on-line diagnosis as it achieves high data rate transmission, interference robustness, bandwidth efficiency and complete spectrum control. Moreover, it allows communication among diagnosis sensors to accurately locate faults position in multi-branch wiring networks which require more than one diagnosis sensor.
