“…The traditional lubrication systems for construction machinery, with their increasingly obvious shortcomings, have not been able to meet the lubrication needs of modern construction machinery [8,9]. Therefore, intelligent lubrication systems came into being, which combine hydraulic technology, sensor technology, numerical control technology, other technologies, a high degree of intelligence in the control system, monitoring, and detection, and strong human-computer interaction, and they can realize multi-point simultaneous lubrication and can control the amount of oil supplied [10][11][12][13].…”
