Abstract
An apparatus, method, and a non-transitory programmed medium provide real time, in-situ, persistent monitoring of a pump for the presence of anomalies and controlling pump operation to avoid a failure. Real time operating data is compared to profiles to indicate out of limit operation and to generate dynamic control signals. A vibration sensor which measures amplitude of vibration generated by the pump and at least one thermocouple provide data to a first processor collocated with the pump to enable low latency reaction. Spectral analysis is performed by the first processor. Additional operating parameter values are obtained and provided to a second processor, a remote processor or a cloud server. At least one of the processors provides signals to modulate controls to vary engine speed or shut down the engine. A cellular modem and a satellite modem interface the system and external nodes. Data collected are correlated with operating data to generate profiles indicative of conditions.
