Cost Effective Low Power Vibration Monitoring System

Abstract

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.
