TRENDING MACHINE HEALTH DATA USING RFID TRANSPONDERS

摘要

A system for monitoring and recording health data associated with machine. The system employs a radio frequency identification (RFID) transponder, which is affixed to the machine. The system utilizes a digital memory component of the RFID transponder to record and maintain historical measurements to aid in determining machine condition trending. The RFID transponder interacts with a machine condition advisor (MCA), where the MCA obtains a configuration and historical data from the RFID transponder, queries sensors, collects data, transfers updated data to the RFID sensor, and determines and displays condition trending. Machine condition trending can be displayed in a graphical format. Warning or alarm levels can be established enabling the system to determine machine conditions warranting alerting a machine technician. Each machine condition trending can be independent of or associated with the associated warning or alarm level.

主权项

1. A method of monitoring a health of a machine, the method comprising steps of:
installing a radio frequency identification (RFID) transponder into a machine, wherein the RFID transponder includes:
a radio frequency identification (RFID) antenna,a radio frequency identification (RFID) transmitter in signal communication with the RFID antenna,a radio frequency identification (RFID) receiver in signal communication with the RFID antenna,a digital memory element including a series of memory blocks established for retaining historic measurements,a microprocessor in signal communication with and operational control of the digital memory element, the RFID transmitter and the RFID receiver; removably coupling a machine condition advisor (MCA) to the machine, the MCA comprising a sensor input and a microprocessor, wherein the microprocessor operates in accordance with a series of machine condition instructions; obtaining machine condition measurement data through the MCA; and transferring the obtained machine condition measurement data to the historic measurement memory blocks.
