Pegase

PEGASE is the wireless platform developed by the team. The milestones for the PEGASE platfom in 2019 are

• finalization of the PEGASE3 hardware and software platform: SDK, decoding FPGA-based GPS frames,

• capacity (demonstrated during work with CEA Lost) of synchronous transmission / reception and ultrasonic wave phase.

• Writing documentation associated with the platform (User Guide ...).

• Start of the valuation process.

A prototype for modal analysis with several PEGASE platforms was developed. To obtain detailed modal information of large and very large structures, many sensors would be required to cover the geometry of the structure with a reasonable accuracy. However, when only a limited amount of sensors is available, large structures can be measured in several sensor setups, where some sensors remain fixed and some are moved between different measurement setups. With the sensors connected to different wireless platforms, the synchronous acquisition of data is required. A solution of data acquisition synchronization, as well as signal processing for merging the information taking into account the change of sensor positions and environmental variability has been developed and presented at IWSHM [31].
