Abstract

A predictive fault determining system includes a non-stationary operating device and a stationary fault determining device that communicates with the operating device using wireless transmissions. The non-stationary operating device includes sensors determining status data of the operating device and a processing device to combine the status data, generating a status signal and wirelessly transmitting the status signal to the fault determining device. Using a wireless receiver, the fault determining device extracts the status data and calculates condition data for the operating device including condition levels, indicating a likelihood of at least one operational failure. Wirelessly, a condition data signal having the condition levels therein is transmitted to the non-stationary operating device, such that the resident processing device may determine if a warning notification should be generated based on selecting a condition level for various elements by comparing the status data to the condition data.
