Abstract
A monitoring method and device which is capable of determining the overall fitness or condition of the device being monitored while simultaneously detecting unknown or unrecognized vibration frequencies. In addition, setting threshold values corresponding to the environment surrounding the device reduces the incidence of false alarms. False alarms may be controlled while detection of true alarms may be maximized by assigning values indicative of thresholds crossed and averaging the values before issuing an alarm. The monitoring system may also provide detailed information as to the operating condition of the device so as to allow the device to operate closer to its margin of safety. Thus, the device may handle more power or speed, without the need to modify the physical design. In addition, an onboard processing unit may be used to determine when the physical load on the device is approaching its physical limits and warn the operator so as to prevent the device from exceeding those limits.
