LINE REPLACEABLE UNIT HEALTH NODES AND METHODS FOR DETERMINING MAINTENANCE ACTIONS RELATING TO LINE REPLACEABLE UNITS

摘要

Line Replaceable Unit (LRU) health nodes are provided, as are methods for determining maintenance actions with respect to LRU health nodes. In one embodiment, the LRU health node includes a passive Radio Frequency identification (RFID) module having an RFID memory and an RFID antenna coupled thereto. The LRU health node further includes a mass storage memory, a sensor configured to monitor an operational parameter of an LRU and generate a corresponding output signal, and a health node controller operably coupled to the passive RFID module, to the mass storage memory, and to the sensor. The health node controller is configured to: (i) record the output signal generated by the sensor in the mass storage memory as time-phased sensor data, (ii) derive health summary data from the time-phased sensor data, and (iii) store the health summary data in the RFID memory.

1. A Line Replaceable Unit (LRU) health node, comprising:
a passive Radio Frequency identification (RFID) module, comprising:
an RFID memory; andan RFID antenna coupled to the RFID memory and enabling wireless access thereto when energized by an interrogation signal; a mass storage memory; a sensor configured to monitor an operational parameter of an LRU and generate a corresponding output signal; and a health node controller operably coupled to the passive RFID module, to the mass storage memory, and to the sensor, the health node controller operable in an active recording mode in which the health node controller: (i) records the output signal generated by the sensor in the mass storage memory as time-phased sensor data, (ii) derives health summary data from the time-phased sensor data, and (iii) stores the health summary data in the RFID memory.
