Bluetooth and Zigbee based Wireless Data Acquisition System for Vibration Monitoring using Labview

Condition monitoring of machinery involves vibration analysis of the machine part. Vibration measurement is prerequisite for condition monitoring and vibration analysis. This paper presents development of a reliable and low cost wireless 4-channels wireless data acquisition system for vibration monitoring. In the developed monitoring system, 3 Axis digital output MEMS Accelerometer sensor has been used as vibration sensor. For data processing Arduino Uno microcontroller board has been used. The implemented system uses Bluetooth and ZigBee communication protocols for wireless transmission of the data form Sensor Unit to Vibration Monitoring Unit. National Instruments’s VISA drivers have been installed in the computer to add serial instruments in LabVIEW. Graphical user interface and alarm generation have been done using National Instrument’s LabVIEW software on the PC. Software development has been done for continuous display of vibrations on four continuous charts. Also alarm generation and data logging features have been added. This system has industrial applications such as vibration analysis, safety control and condition monitoring.
