Microcontroller Based Data Acquisition System For Electrical Motor Vibrations using VB software.
Journal Title: Indian Journal of Computer Science and Engineering - Year 2011, Vol 2, Issue 5
Abstract
The electrical machine parameters under various operating conditions play a vital role in the considerations for the performance, efficiency, reliability and life of machine. Vibration signals measured at the external surfaces of a machine contain a great deal of information as to the internal processes. Hence it is considered as a very important parameter to monitor machine health. Hence such parameters should be constantly measured & monitored & its data acquisition should be carried out so that the data is available for the control of these parameters and also in the automation of different machine dependent processes. Also the data is to be stored so that it can be retrieved for future references & innovations. There are different parameters of motor viz voltage , current , flux, torque, speed power factor, heat rise ambient temperature and vibrations that are needed to be measured & monitored under different operating conditions of motor. This project focus on the measurement & monitoring of the parameter viz vibrations out of these parameters. This parameter is very important in performance , reliability & life of machine and also play a vital role in the safety point of view. The proposed system comprises of sensor, analog to digital converter , signal conditioning circuit, microcontroller 8051.These parameters will be constantly measured and displayed and if they cross a safety limit, the control action can be taken. Thus the future scope of the project is that more channels for measurement of more parameters such as temperature & humidity or 3-dimensional vibrations etc can be added & control methods for these parameters can be designed & developed as the further step of monitoring. Also hardware configuration can be changed to improve the speed.
