13. 5. Partial synthesis In this chapter, a general approach for obtaining monitoring data, reliable and exploitable for a PHM application is proposed. Three steps are highlighted: 1) Choice of critical components. ), and then deploying a PHM approach. Acquisition: From System to Data 31 2) Definition of physical parameters to be monitored and choice of sensors to be installed. Anticipating failure phenomena requires as a minimum the ability to observe these phenomena. Therefore, the goal of this phase is to lay the foundations for a monitoring system (physical parameters to measure and associated sensors).

5). 5. Simplified and illustrated structure of an acquisition chain Acquisition. 6). The role of these cards is to acquire (input) and to deliver (output) some signals (input/output cards). Inputs and outputs can be analog and/or digital, depending on the intended application. Two types of cards exist: cards that can be plugged into the central unit of a computer, and external cards (or pluggable into an external dedicated casing). Most of the cards dedicated to data acquisition include signal conditioners, filters, multiplexers, and analog to digital converters.

At the first decomposition level, the signal passes through LP to produce an approximation signal (A1), and through HP to produce a detail signal (D1). The approximated signal is characterized by half of the points (256), whereas frequency resolution is doubled since the frequency band has been halved ([0 − π2 ]). 5) in order to construct A2 and D2, and this process can be repeated as many times as desired. The features extracted using WPD correspond to energy coefficients of decomposition levels.
