Low-cost online diagnosing of a pumping station

The paper presents an approach to the online estimation of the degree of degradation of the pump-pipeline assemblies of domestic or municipal low-power sewage pumping stations. The two types of faults are of concern: leakage and obliteration. The potential applicability is the main advantage of the proposed approach. It is because it does not require installing any additional instruments dedicated specially for diagnostic purposes. Moreover, it may be easily implemented in almost all programmable controllers. We calculate the diagnoses of pumping stations using heuristic knowledge, subjective logic, and timing of pumping station control cycles. Finally, we show the chosen results of simulations of faults in a low-power pumping station.
