The wear degree of sheet separating machine blades refers to the material loss on the blade surface caused by long-term mechanical friction, which directly affects the blade quality and equipment service life. Machine vision-based wear degree detection collects blade surface images via high-resolution industrial cameras, quantifies the features of wear areas with image processing technologies, and establishes a digital characterization model for wear states. This monitoring data has the following application scenarios: ### Internal Enterprise Scenarios 1. Combine wear degree prediction data with historical equipment operation records to establish blade health files and optimize equipment replacement cycle decisions. 2. Feed back the wear degree prediction results to the blade parameter adjustment system to realize the "wear compensation algorithm". 3. The accumulated abnormal threshold parameters and coefficient weights can form an enterprise equipment health evaluation standard library, providing data support for subsequent equipment selection and process improvement. ### External Enterprise Scenarios 1. Provide wear degree prediction algorithm interfaces to sheet separating machine manufacturers to help them upgrade their equipment intelligent diagnosis systems. 2. After coefficient adjustment, this model can be adapted to more than 80% of cutting equipment. 3. After docking equipment fault index data with the Industrial Internet Platform, value-added services such as equipment leasing insurance pricing and supply chain financial risk control can be derived. #### 1. Data Collection Data is collected from industrial cameras, edge detection algorithms, and acceleration sensors. Real-time collection of operating parameters such as the wear area of the sheet separating machine, the initial surface area of the blade, and the crack length is carried out daily. The data collected by the sheet separating machine is processed after denoising, cleaning and preprocessing. #### 2. Data Processing Wear area abnormality degree = Wear area / Initial blade surface area Crack length abnormality degree = Maximum crack length / Crack length threshold Color difference abnormality degree = Current surface color / Initial surface color Vibration frequency abnormality degree = Blade vibration frequency / Vibration reference frequency Wear degree = Wear area abnormality degree * Wear area coefficient + Crack length abnormality degree * Crack length coefficient + Color difference abnormality degree * Color difference coefficient + Vibration frequency abnormality degree * Vibration frequency coefficient The four coefficients need to be determined through machine learning training, with a total sum of 1. The smaller the wear degree, the healthier the equipment. When the wear degree is greater than or equal to 2.3, the equipment is in a fault state and should be shut down for maintenance immediately; when the wear degree is less than or equal to 1.8, the equipment is in a normal state and the routine operation and maintenance plan should be maintained; when the wear degree is in the range of 1.8 to 2.3, the equipment is in a pre-warning state and the frequency of inspections should be increased.
