Cost Effective Low Power Vibration Monitoring System

The prime objective of this research work is to present prompt, cost effective, and an ultra low power online vibration monitoring system using a microcontroller (MSP430f6638) and also transmit the vibration signal in the form of 4-20 mA, wired or wireless signal. As vibration is a very crucial parameter, its measurement is a prerequisite in mechanical industries to predict machine health, and to take proactive maintenance steps before the occurrence of any failure, or a major fault. A microcontroller-based system has been introduced that can measure and monitor vibration signals coming from different mechanical machineries and display it on a LCD, with an alarm and trip feature. Another key objective of this project is to present a very low cost signal conditioning circuit, and display the root mean square (RMS) value of acceleration and velocity which will show the deterioration rate of machine health. A 3.3V switching regulator using IC TPS54062 has been designed for getting energy efficient output, which is a very significant part of the proposed system. Our system offers two options for vibration measurement and monitoring — wired and wireless — so the appropriate option can be chosen based on the requirement. This project presents a scientific direction and development of vibration signal measurement and monitoring system.
