Online data monitoring can realize real-time monitoring of the quality of lubricating oil in use. Through real-time monitoring and analysis of its physical and chemical properties, wear particles and other indicators, timely fault analysis can be made on vehicle gearboxes and other equipment.

[0003] The oil data online sensor is the core of the entire oil online monitoring and the source of intelligent diagnostic data. Oil data online monitoring is usually collected in real time. When the vehicle is in the process of driving, due to sudden acceleration or bumps, it usually causes the oil sensor to vibrate.
