At present, the most common method for monitoring oil abrasive particles in China is an off-line measurement method such as a spectrum technology and a ferrographic technology, and the method has the defects of complex equipment, high manufacturing cost, failure early warning delay caused by the fact that the operation state of a system cannot be monitored in real time and the like. A micro-flow channel monitoring method is generally adopted in a domestic optical image-based monitoring method, but the method can only be applied to off-line monitoring or branch sampling monitoring of micro flow, so that the problems of abrasive particle chaining and poor real-time effect of bypass on-line monitoring exist in the method. If the method is applied to on-line full-flow monitoring, the results of low monitoring sensitivity and delayed fault detection can be caused. For the full-flow online monitoring method, technicians perform full-flow online monitoring through a raspberry pi (microcomputer), but the full-flow online monitoring method is limited by the low raspberry pi frame frequency, and when the oil flow rate is high in the full-flow state in industrial application, the raspberry pi optical monitoring system cannot meet the acquisition requirement.
With the rapid development of the image recognition technology, the visible light high-speed camera is increasingly widely applied, and it is very important to provide a complete visible light high-speed camera-based full-flow oil dynamic abrasive particle online monitoring system suitable for the actual industrial environment in consideration of the fact that the visible light high-speed camera is used in an oil online monitoring system to acquire dynamic abrasive particle images of large-scale complex mechanical equipment at a high flow rate in real time, and further perform full-flow real-time online monitoring and fault early warning on the lubricating system of the large-scale complex mechanical equipment.

The invention uses the camera to collect images, but aims at the position of the filter membrane, solves the problem that the static collection of the hydraulic oil is limited, the detection is delayed, and the real-time performance is poor.
