Wireless vibration monitoring of movable engine parts
First Claim
1. A system, comprising:
- a wireless sensor disposed in a recess of a shank of a connecting rod internal to a reciprocating internal combustion engine and to communicate wirelessly; and
a controller comprising a processor configured to;
initiate communication with the wireless sensor by receiving a wireless signal indicative of a frequency of vibration of the connecting rod from the wireless sensor;
obtain an acceptable threshold range of vibrations for the connecting rod from one or more data sources;
determine whether the frequency of vibration is within the acceptable threshold range of vibrations for the connecting rod; and
initiate preventative actions when the frequency is not within the acceptable threshold range, wherein the preventative actions comprise stopping operation of the reciprocating internal combustion engine.

Abstract
Condition based engine parts (e.g., movable engine parts) monitoring is disclosed. The techniques may enable detecting cracks present in engine parts while the engine is operational. In one embodiment, a system includes a wireless sensor configured to be disposed on a movable part internal to a machine and communicate wirelessly and a controller that includes a processor. The processor may be configured to initiate communication with the wireless sensor by receiving a wireless signal indicative of a frequency of vibration of the internal movable part from the wireless sensor, to obtain an acceptable threshold range of vibrations for the internal movable part from one or more data sources, to determine whether the frequency of vibration is within the acceptable threshold range of vibrations for the internal movable part, and to initiate preventative actions when the frequency is not within the acceptable threshold range.
