WARNING DEVICE FOR MONITORING A HEALTH STATUS OF A BEARING HAVING A CLOSE RANGE WIRELESS INTERFACE
First Claim
1. A warning device for monitoring a health status of a bearing mounted to a piece of rotating machinery in an industrial environment having a close range wireless interface, the warning device comprising:
- a body portion connected to a top portion and a base portion, a microcontroller for controlling the device, a battery for powering the device, at least one sensor for sensing at least one of a velocity, an enveloped acceleration and a temperature reading of the bearing, and at least one illuminating device for displaying the health status of the bearing according to input from one of the at least one sensors;
the close range wireless interface including;
an RFID tag having an integrated circuit for storing and processing information, and a radio for modulating and demodulating a radio-frequency signal,an antenna for receiving and transmitting the modulated and demodulated signal, and connected to the RFID tag, anda digital bus connecting the microcontroller to the RFID tag, whereinthe microcontroller stores at least one of the sensed velocity, enveloped acceleration and the temperature values into a memory disposed within the RFID tag, and whereinthe memory is a dual access memory that enables data transfer via the RFID radio or via the digital bus.

Abstract
A warning device having a close range wireless interface is provided. The warning device includes a body portion, top portion, a base portion, a microcontroller for controlling the device, a battery, at least one sensor for sensing at least one of a velocity, an enveloped acceleration and a temperature reading of the bearing, and at least one LED for displaying the health status of the bearing.
The close range wireless interface includes an RFID tag having an integrated circuit, and a radio, an antenna for receiving and transmitting modulated and demodulated signals, and a digital bus connecting the microcontroller to the RFID tag. The microcontroller stores at least one of the sensed velocity, enveloped acceleration and the temperature values into a memory disposed within the RFID tag. The memory is a dual access memory that enables data transfer via the RFID radio or via the digital bus.
