The collection system completes the video information collection of the lubricant in a flowing state under a microscopic state in the multi-light source field of view. The storage system is responsible for storing the collected original microscopic video information and the processed information extraction results. The processing system extracts the information contained in the lubricant, including abrasive particle concentration, abrasive particle size, abrasive particle characterization information, non-wear medium statistics, etc. The human-computer interaction system displays the original video information, processing process, device self-detection status, operation reminders and processing part information; the human-computer interaction system is responsible for sending the operation action to the control system (such as an ARM control board) in the form of instructions according to the device function, and then the control system controls the diversion system and the collection system to execute the corresponding instructions. The control system (such as an ARM control board) is responsible for completing the control of the entire information collection process according to the instructions of the human-computer interaction system; the diversion system (one of the action execution parts) completes the switching of lubricating oil / flushing fluid according to the control of the ARM control board; the acquisition system (the second action execution part) completes the control of the multi-light source field of view of the acquisition system and the control of the microscopic image acquisition module (such as a microscopic camera) according to the control of the ARM control board; the control system controls the detection of the internal operating state of the wear detection device, the execution of the detection state and the execution of the clear state.

[0109] Specifically, the inlet is divided into a lubricating oil inlet and a flushing liquid inlet. The oil sample or flushing liquid enters the flow state adjustment part through the flow channel switching part for flow state adjustment, and then enters the optical microscopic acquisition module (such as a microscopic camera) in the acquisition system for microscopic video information acquisition. The collected oil sample passes through the pressure detection part and then flows through the outlet for discharge. Among them, the liquid inlet can use a syringe pump to extract the liquid sample, the flow channel switching part can use a reversing valve for switching, the pressure detection part can use a pressure sensor to detect the pressure of the liquid in the flowing state, and the liquid outlet can use an outlet valve.

They are respectively connected to the injection pump, the reversing valve, the light source (i.e., the light source field of view), the camera (i.e., the microscope camera), and the pressure sensor, and the execution strategies are linked according to the flushing, detection, and self-test instructions. In the flushing mode, the injection pump and the reversing valve are controlled by RS232 and AO to extract the flushing liquid, and the flow channel is flushed at a predetermined flow rate to complete the flushing process. In the detection mode, the injection pump and the reversing valve are controlled by RS232 and AO to extract the lubricating oil, and the light source and the camera are turned on to send the lubricating oil to the microscope acquisition module at the detection flow rate to complete the detection process. In the self-test mode, the injection pump, the reversing valve, the light source, and the camera are turned on by RS232 and AO, and the outlet valve is closed to detect the internal pressure and the status of each component to complete the self-test process. Among them, the reversing valve is for injection control, which controls the injection of lubricating oil and flushing liquid respectively; the injection pump controls the flow rate according to instructions; the outlet valve realizes the switching of detection state and flushing state by opening and closing; the light source controls the lighting sequence and brightness through switches and voltages; the camera completes the start and stop control by whether it is powered on or not.

[0112] The diversion system 510, the acquisition system 520 and the control system 530 are integrated into one device as the detection front end, and the processing system 540, the human-computer interaction system 550 and the storage system 560 are integrated into one device as the detection back end. The specific working process is: when the wear detection device (detection front end and detection back end) is powered on and self-checked, it enters the main operation interface (implemented by the human-computer interaction system of the detection back end), and the operation interface mainly issues detection and flushing operation instructions. After the ARM control board (control system) receives the detection instruction issued by the operation main interface, it controls the diversion system to start extracting lubricating oil samples at a preset speed, and turns on the light source and camera of the acquisition system in turn to start collecting video information contained in the lubricating oil; after receiving the flushing instruction issued by the operation main interface, the ARM control board starts the reversing valve to extract the flushing liquid, and controls the diversion system to start cyclic flushing according to the established large flow mode. After receiving the self-check instruction issued by the operation main interface, the ARM control board starts the reversing valve to extract the flushing liquid, turns on the injection pump, the reversing valve, the light source, the camera, and closes the outlet valve to detect the internal pressure and the status of each component.

[0113] A practical operation process of the wear detection device is as follows:

[0114] 1) Power on the execution end (i.e., detection front end) of the detection device;

[0115] 2) Connect to the control PC (i.e. the detection backend) and start the control software to establish communication;

[0116] 3) Place the sample injection tube into the liquid bottle to be tested;

[0117] 4) The wear detection device starts self-checking and enters the operation interface after the self-checking is completed;

[0118] 5) The wear detection device operates autonomously according to the selected function of the operation interface and updates the detection results in real time. Fig. 9 As shown;

[0119] 6) After the test is completed, click Confirm, close the device and recycle the pipeline.

[0120] The present invention precisely controls the flow rate, allows the oil sample to enter the collection field of view in the form of a steady flow, sets the field of view to a light field, and collects the lubricating oil flow information containing abrasive information through a microscope camera. Then, the collected information is marked, measured, counted, compared and output, and digital information and image information with multiple standards and multiple physical quantities are obtained.

[0121] The present invention uses image processing technology to analyze the lubricating oil wear particle information collected microscopically, extracts the physical and surface characteristics related to the wear particles (particles after wear), performs statistical comparison on the processed information, and finally realizes the wear detection function of single extraction and multiple result output.

[0122] The wear detection device of the present invention adopts video acquisition and extraction technology to obtain information contained in lubricating oil more intuitively. The entire detection process adopts optical photography, avoiding secondary processing methods such as electromagnetic and shadow recognition used by other sensors, and reducing the result error caused by process processing. It realizes the extraction results of multiple information through a single acquisition method, which not only reduces the use cost of lubricating oil detection technology, but also reduces technical problems such as installation and compatibility during use.

[0123] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
