The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent consequential damages and avoid its consequences. Condition monitoring has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure.
Predictive maintenance evaluates the condition of equipment by performing periodic (offline) or continuous (online) equipment condition monitoring.The ultimate goal of the approach is to perform maintenance at a scheduled point in time when the maintenance activity is most cost-effective and before the equipment loses performance within a threshold.
System is totally failed and cannot operate as expected; System will function as expected but is degraded; This requires automatic fault detection and reporting. Condition Based Maintenance (CBM) requires clearly observable or audible notification that is suitable for unsophisticated and untrained users, which includes the following.
An intelligent maintenance system is a system that uses data analysis and decision support tools to predict and prevent the potential failure of machines. The recent advancement in information technology , computers, and electronics have facilitated the design and implementation of such systems.
Health and usage monitoring systems (HUMS) is a generic term given to activities that utilize data collection and analysis techniques to help ensure availability, reliability and safety of vehicles. Activities similar to, or sometimes used interchangeably with, HUMS include condition-based maintenance (CBM) and operational data recording (ODR).
Fault reporting is a maintenance concept that increases operational availability and that reduces operating cost by three mechanisms: Reduce labor-intensive diagnostic evaluation; Eliminate diagnostic testing down-time; Provide notification to management for degraded operation; That is a prerequisite for condition-based maintenance.

Cacti is an open-source, web-based network monitoring, performance, fault and configuration management framework designed as a front-end application for the open-source, industry-standard data logging tool RRDtool. [3] Cacti allows a user to poll services at predetermined intervals and graph the resulting data. Through the use of Cacti plugins ...
The system is not intended to replace safety critical warnings such as an aircraft's flight management system but instead to complement them and perhaps also leverage existing sensors for assistance with system health monitoring. Ideal systems to monitor are those systems, subsystems & structural elements which are likely to show graceful ...
