Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
Inflight maintenance checklist procedure before starting waste collection system repair on board the Atlantis shuttle. Corrective maintenance is a maintenance task performed to identify, isolate, and rectify a fault so that the failed equipment, machine, or system can be restored to an operational condition within the tolerances or limits established for in-service operations.
Fault reporting is an optional feature that can be forwarded to remote displays using simple configuration setting in all modern computing equipment. The system level of reporting that is appropriate for Condition Based Maintenance are critical, alert, and emergency, which indicate software termination due to failure.
Fault detection coverage that system built-in test will realize; Whether the analysis will be functional or piece-part; Criteria to be considered (mission abort, safety, maintenance, etc.) System for uniquely identifying parts or functions; Severity category definitions
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.
The two major FASTEMS are the DACS Element Management Systems (DEMS) and the RNC Element Management Systems (RNC-EMS). DEMS is designed to assist NOC with management of DACSs. In the event of a change in the status of the network due to a fiber failure, RAPID forwards this status change to DEMS, which triggers DEMS to isolate the problem.
This is usually handled with a separate "automated fault-detection system". In the case of the tire, an air pressure monitor detects the loss of pressure and notifies the driver. The alternative is a "manual fault-detection system", such as manually inspecting all tires at each stop. Interference with fault detection in another component.
Equipment service management and rental (ESM&R) refers to equipment services management throughout the heavy equipment life cycle. Increased competition and slim margins in heavy equipment sales and rental place a heavy burden on manufacturers, dealers, rental companies and service businesses to improve their service performance.
