A method for accumulating fault condition data from a hierarchical system is presented comprising monitoring an operation of a component with a computing node that includes a processor and a memory. The memory contains a configuration file comprising failure modes (FM), symptoms, tests that identify the symptoms and a corrective action for the symptom. The method further comprises populating at least one of the processor and the memory of the computing node with one or more standardized executable application modules (SEAM) and a workflow service. The one or more SEAMS is configured to create a fault condition record by collecting all FMs that manifest the symptom. For all FMs collected, a list of unique symptoms is produced. Further all tests that can identify the listed unique symptoms and all of the corrective actions associated with the FMs that manifest the symptom are determined from the memory device.

A system for reconfiguring a node of a complex system health monitoring system without recompiling and relinking executable code is provided. The system includes a software module containing previously compiled instructions to perform one of a plurality of different standardized functions and a computing node comprising a processor and plurality of software objects, the processor configured to execute the previously compiled instructions. The system further includes a configuration file configured to provide static and dynamic data to the software module, the configuration file comprising a dynamic data store (DDS), a static data store (SDS) and a binary code database (BCD). The BCD comprises a library of externally compiled executable algorithms that are callable by the software module. The BCD being configured with database identification and retrieval data structures associated with library of externally compiled executable algorithms.

Methods and reconfigurable systems to incorporate customized executable code within a condition based health maintenance system without recompiling base code

Methods and reconfigurable systems are provided for monitoring the health of a complex system. The system may include, but is not limited to a computing node including a memory and a processor. The processor can be configured to receive a plurality of standardized executable application modules, each standardized executable application module containing instructions to perform one of a plurality of different standardized functions, receive a binary file comprising instructions, which when loaded into memory by the processor, configure the standardized executable application modules and configure the memory by creating at least one data structure in the memory used by at least one of the plurality of standardized executable application modules.

Systems and methods to configure condition based health maintenance systems

Systems and methods are provided for customizing workflow in a condition based health maintenance ('CBM') system computing node. The computerized method comprises identifying a first standardized executable application module ('SEAM'), wherein the first SEAM is configured to generate a first event associated with particular data being processed by the first SEAM and identifying a second SEAM, wherein the second SEAM is configured to generate a subsequent event associated with the particular data processed by the first SEAM. The computerized method further comprises creating a quasi-state machine associating a unique responses to the first event and associating a unique responses to the subsequent event, and installing the quasi-state machine into the SDS of the computing node from which the workflow service state machine retrieves the one or more unique responses from the quasi-state machine to the first event for processing by the second SEAM to produce the subsequent second event.

Systems and methods for limiting user customization of task workflow in a condition based health maintenance system

Methods and reconfigurable systems are provided for monitoring the health of a complex system. The reconfigurable system comprises a plurality of standardized executable application modules containing instructions to perform one of a plurality of different standardized functions. The system further comprises a plurality of computing nodes arranged in a hierarchical structure comprising one or more layers of computing nodes. Each computing node of the plurality runs a host application and a workflow service module, each computing node thereby being configured by a configuration file that directs the execution of any of the standardized executable application modules in a cooperative fashion by the host application via the workflow service module. The system also comprises a loading means for populating each computing node with one or more standardized executable application modules of the plurality, a communication means, and a configuration means for programming the populated standardized executable application modules.

Methods and reconfigurable systems to optimize the performance of a condition based health maintenance system

Systems and Methods are provided for coordinating computing functions to accomplish a task. The system includes a plurality of standardized executable application modules (SEAMs), each of which is configured to execute on a processor to provide a unique function and to generate an event associated with its unique function. The system includes a configuration file that comprises a dynamic data store (DDS) and a static data store (SDS). The DDS includes an event queue and one or more response queues. The SDS includes a persistent software object that is configured to map a specific event from the event queue to a predefined response record and to indicate a response queue into which the predefined response record is to be placed. The system further includes a workflow service module, the work flow service module being configured to direct communication between the SDS, the DDS and each of the plurality of SEAMs.

A method of processing a plurality of tracks representative of one or more target aircraft in a vicinity of a surveillance aircraft, where each track is generated in response to target reply signals provided by the target aircraft in response to interrogation signals transmitted by the surveillance aircraft, includes eliminating a portion of the plurality of tracks which are duplicate tracks of the same target aircraft. The remaining tracks are maintained and updated in response to the target reply signals provided by the target aircraft. A threat level for each of the remaining tracks is determined and two or more of the remaining tracks which are possibly representative of a same target aircraft are merged resulting in a composite track. The composite track is output to a display device utilizing information from a particular remaining track of the composite track having the greatest threat level to the surveillance aircraft while continuing to maintain and update all the remaining tracks.
