Diesel engine oil pressure control method and system

The invention belongs to the technical field of diesel engine control, and provides a diesel engine oil pressure control method and system. Correcting the engine oil pressure data by adopting the engine oil temperature; determining a corresponding alarm level according to the pressure data after temperature correction; wherein the setting of the alarm grade is determined according to the rotating speed of the diesel engine; controlling the engine oil pressure according to the alarm grade; the engine oil pressure data is corrected by adopting the engine oil temperature, so that the steady-state engine oil pressure alarm is more accurate, and the problem of high engine oil pressure false alarm caused by insufficient heating of a diesel engine when a standby generator set is operated is avoided; meanwhile, two factors of the engine oil pressure and the rotating speed of the diesel engine are considered, so that when the engine oil pressure is dynamically judged, the rotating speed change is combined, engine oil
