Objectives
The objective of this experiment is to monitor vibration using wireless based vibration measurement system.
Introduction
Induction motors are the most common and frequently encountered machines in industry due to its simple design, rugged, low-price, easy maintenance and it runs essentially as constant speed from no-load to full load etc. It is estimated that about 40% of the induction motor failures are caused by bearing failures, 38% by stator winding faults, 10% by rotor faults and 12% by miscellaneous faults.
To maintain safety, reliability, efficiency and uptime condition monitoring and fault diagnostics should be done in prior. Primary detection of failures in motor system through fault detection and prediction allow maintenance to be scheduled to prevent tragic failures in motor, avoiding expensive economical losses associated with process downtime caused by motor failure. Traditionally condition monitoring and fault diagnostics systems in industrial plants are recognized in an offline fashion or in wired systems designed by communication cables and various types of sensors. The installation and maintenance of these cables and sensors are usually much more expensive than the cost of sensor themselves.
The progress in wireless communication and integrated electronics has supports the implementation of low cost, low power, multifunctional sensors and actuators resulted in the development of wireless sensor networks. The advantages of wireless sensor network over traditional sensing techniques include flexibility, high fidelity, low cost, self organization and aggregated intelligence. These exceptional features make wireless sensor networks a favorable platform for online and remote implementation of condition monitoring and fault diagnostics system.
