Data Acquisition System
System Overview
LYRA is a true wireless data acquisition system consisting of LYRASens (vibration/temperature), LYRALink (IO-Link and analogue interface for the measurement of the electrical current, temperature and relative shaft vibration) and LYRAGate (gateway with Modbus interface for data transfer in MoonStone) and LYRAMesh
Our sub-GHz wireless radio technology grants for long reading range in harsh industrial environments. Its bi-directional communication allows to configure and maintain the system remotely. The TDMA/FHSS MAC ensures the time synchronisation below 0.1ms between all connected devices so that structured data is acquired.
Data acquired in the gateway LYRAGate is stored, managed and analysed in our web-app MoonStone Blue. All LYRA devices can be remotely configured.

LYRA Acquires trend and raw data
Trend Data
Trend data is physical parameters such as overall vibrations, temperatures, power, pressure, flows,…. collected typically every hour. LYRA acquires SCADA data (modbus RTU/TCP) with LYRAGate, sensors data (IO-Link or analogue inputs) with LYRALink or overall vibration data with LYRASens. Trend data is collected on schedule and is used to build Digital Twins.
Raw Data
Raw data is a large set of acceleration data (up to 100k data) collected at high sampling rate (up to 4kHz) with LYRASens. Raw data is collected on schedule or on event and is used for the vibration analysis of rotating machines and in robotic.

MoonStone Blue features
Data Acquisition
- Acquisition from LYRAGate, LYRASens and LYRALink.
- Acquisition of trend data (calculated in the sensor) and raw data.
- Acquisition triggers:
- Time-based - scheduler
- Event-base - automatic when the sensor is moving with post and pre-triggering
- Condition-based - automatic when the machine is rotating
- On-demand - 5s reaction time
- Triggering of synchronised acquisition on a group of sensors (multicast) or on all data sensors (broadcast) connected to the gateway
Data Management
- Data managed per site, section, machine and measurement point.
- Sensors’ data connected to each measurement point so that data continuity is ensured even in case of sensors replacement.
- Full remote configuration of LYRASens (e.g. acquisition parameters) and LYRAGate.
- Remote firmware upgrade of LYRASens and LYRAGate.
- LYRA infrastructure monitoring (e.g. batterie voltage, RSSI,…).
Data Visualisation
- Trend view of data
- Analysis view of raw data in time and frequency spaces (FFT, wavelets, hilbert)
