[0060] In order to enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0061] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0062] In the prior art, a ferrograph is usually used to test an oil sample. The ferrograph includes a light source and a light detector. When the oil sample enters the detection area of the ferrograph, the oil sample will block the light emitted by the light source and reduce the light intensity incident on the light detector. According to the change in the light intensity detected by the light detector, the ferrograph can analyze the distribution of metal wear particles in the oil sample. However, when the light transmittance of the oil sample is too poor or the oil sample contains too many opaque non-magnetic impurities, the oil sample will block all the light, causing the light detector to not receive any light, resulting in the ferrograph being unable to analyze the distribution of metal wear particles in the oil sample.

[0063] To solve the above problems, an embodiment of the present invention provides a detection method for a ferrograph, where the ferrograph includes a light source and a light detector; the light source is used to emit a detection beam; the light detector is used to detect the light intensity data after the detection beam is incident on the detection area. Figure 1 is a flowchart of a detection method for a ferrograph provided by an embodiment of the present invention. Refer to Figure 1 , the detection method includes:

[0064] S101. Extract an oil sample and control the metal wear particles in the oil sample to be adsorbed on the detection area.

[0065] Specifically, an oil sample can be extracted by controlling an oil sample extraction structure, and the oil sample extraction structure can be a pump, for example. The pump extracts the oil sample through a sample tube, and the sample tube is a pipeline for transporting the oil sample. One end of the sample tube is immersed in the oil sample, and the pump can extract the oil sample into the sample tube. The sample tube includes a light-transmitting area, which is the detection area. The sample tube in the detection area is usually made of glass to allow the detection beam to enter and exit. The ferrograph also includes a magnetic module, which can adsorb the metal wear particles on the detection area so that the ferrograph can detect the distribution information of the metal wear particles.

[0066] S102. Receive the first light intensity data based on the detection beam incident on the detection area by the light detector.

[0067] After the detection starts, the light source emits a detection beam. The detection beam irradiates the detection area. Part of the detection beam is absorbed by the oil sample and metal wear particles, and the remaining detection beam is transmitted through the detection area and received by the light detector. The light detector generates the first light intensity data according to the received light intensity and sends the first light intensity data to the control module. The control module can receive the first light intensity data based on the detection beam incident on the detection area by the light detector.

[0068] S103. If the first light intensity data is greater than or equal to the first preset data, after the extraction of the oil sample is completed, extract a blank sample and control the blank sample to enter the detection area.

[0069] Among them, the transmittance of the blank sample based on the detection beam is greater than the transmittance of the oil sample except for the metal wear particles based on the detection beam.

[0070] Specifically, when the transmittance of the oil sample is relatively high, the fewer the detection beams received by the photodetector, the more the detection beams absorbed by the metal wear particles. The first light intensity data is a value representing the amount of metal wear particles. The fewer the detection beams received by the photodetector, the larger the first light intensity data. When the transmittance of the oil sample is too low, not only the metal wear particles absorb the detection beams, but also the oil sample and impurities absorb a relatively large amount of detection beams. At this time, the larger the first light intensity data, the more the detection beams absorbed by the oil sample and metal wear particles. The first preset data is a value used to determine whether the photodetector has received sufficient light intensity. If the first light intensity data is greater than or equal to the first preset data, it indicates that the oil sample and metal wear particles have absorbed most of the detection beams, and only a very small amount of detection beams are received by the photodetector. This will result in a large error in the first light intensity data, and the ferrograph cannot analyze the distribution information of the metal wear particles based on this first light intensity data. This is because the light transmittance of the oil sample itself is poor, or too many opaque non-magnetic impurities are mixed in the oil sample, resulting in poor light transmittance of the oil sample. This makes it so that no matter how many metal wear particles are contained in the oil sample, the photodetector can hardly receive the detection beams. At this time, it is necessary to remove the oil sample and impurities other than the metal wear particles, so that the ferrograph can detect the distribution of the metal wear particles.

[0071] Extracting a blank sample can move the oil sample and impurities with poor light transmittance out of the detection area. Since the transmittance of the blank sample based on the detection beam is greater than that of the oil sample other than the metal wear particles based on the detection beam, allowing the blank sample to enter the detection area can increase the transmittance of the detection area, thereby increasing the light intensity received by the photodetector. At the same time, the metal wear particles are adsorbed to the detection area by the magnetic module, so the metal wear particles will not be washed away by the blank sample.

[0072] Optionally, the blank sample can include tetrachloroethylene. Tetrachloroethylene has good light transmittance and can wash the oil sample on the surface of the metal wear particles clean.

[0073] S104. Receive the second light intensity data based on the detection beam incident on the detection area by the photodetector, and determine the distribution information of the metal wear particles at least according to the second light intensity data.

[0074] Specifically, after the blank sample enters the detection area, the light intensity received by the photodetector increases. Thus, the second light intensity data generated by the photodetector according to the light intensity of the received detection beam can reflect the distribution information of the metal wear particles. The control module receives the second light intensity data and can determine the distribution information of the metal wear particles according to the second light intensity data. The distribution information includes, but is not limited to, the number of metal wear particles per unit volume of the oil sample.

[0075] In the detection method provided by the embodiment of the present invention, when the first light intensity data is greater than or equal to the first preset data, by extracting a blank sample, a blank sample with a higher transmittance is used to replace the oil sample and impurities with poor transmittance, thereby improving the transmittance of the detection area, increasing the light intensity of the detection beam received by the photodetector, and thus improving the signal-to-noise ratio of the second light intensity data. This solves the problem that metal wear particles cannot be detected due to the turbidity of the oil sample, enables the second light intensity data to better reflect the distribution information of metal wear particles, and improves the accuracy of detection.

[0076] Figure 2 FIG. is a flowchart of another detection method for a ferrograph provided by an embodiment of the present invention. Since the transmittance of the blank sample is not 100%, while the metal wear particles absorb the detection beam, the blank sample will also absorb part of the detection beam. To eliminate this part of the error, Figure 2 The detection method shown further explains how to eliminate the error caused by the blank sample absorbing the detection beam on the basis of the above embodiment. Refer to Figure 2 , the detection method includes:

[0077] S201. Extract a blank sample and control the blank sample to enter the detection area.

[0078] Before starting to detect the oil sample, it is necessary to first detect the light transmittance of the blank sample so that after obtaining the second light intensity data, the distribution information of metal wear particles can be determined by combining the second light intensity data and the light transmittance performance of the blank sample, thereby making the detection result of metal wear particles more accurate. Figure 3 FIG. is the first operation interface schematic diagram of the detection method provided by an embodiment of the present invention. Refer to Figure 3 , click "Turbidity Test", and the interface will display "Put the sample tube into the solvent and click Run Baseline". One end of the sample tube is connected to a pump. The sample tube can be put into the blank sample to extract the blank sample. Then, the sample number needs to be input. Each sample number corresponds to a type of oil sample to determine the type of the oil sample. Figure 4 FIG. is the operation interface schematic diagram for inputting the sample number of the detection method provided by an embodiment of the present invention. Figure 5 FIG. is the second operation interface schematic diagram of the detection method provided by an embodiment of the present invention. Refer to Figure 5 , after inputting the sample number, click "Run Baseline" to extract the blank sample.

[0079] S202. Receive the third light intensity data of the photodetector based on the detection beam incident on the detection area.

[0080] Specifically, after the blank sample enters the detection area, part of the detection light beam will be absorbed by the blank sample, and the remaining detection light beam will pass through the detection area and be received by the photodetector. The photodetector generates third light intensity data based on the received light intensity and sends the third light intensity data to the control module.

[0081] S203. Extract an oil sample and control the metal wear particles in the oil sample to be adsorbed in the detection area.

[0082] Figure 6 is the schematic diagram of the third operation interface of the detection method provided by the embodiment of the present invention. Refer to Figure 6 , after obtaining the third light intensity data, the interface will display "Put the sample tube into the sample - Press Start". Put the sample tube into the oil sample and click "Start" to extract the oil sample. Figure 7 is the schematic diagram of the fourth operation interface of the detection method provided by the embodiment of the present invention. Refer to Figure 7 , start to extract the oil sample, and the interface displays "Waiting for oil". Figure 8 is the schematic diagram of the fifth operation interface of the detection method provided by the embodiment of the present invention. Refer to Figure 8 , after the oil sample enters the detection area, the interface displays "Wait for completion after cleaning with solvent". After the oil sample extraction is completed, move the sample tube into the blank sample to extract the blank sample again.

[0083] S204. Receive the first light intensity data of the photodetector based on the detection light beam incident on the detection area.

[0084] S205. If the first light intensity data is greater than or equal to the first preset data, then after the oil sample extraction is completed, extract a blank sample and control the blank sample to enter the detection area.

[0085] Among them, the transmittance of the blank sample based on the detection light beam is greater than the transmittance of the oil sample except for the metal wear particles based on the detection light beam.

[0086] S206. Receive the second light intensity data of the photodetector based on the detection light beam incident on the detection area, and determine the distribution information of the metal wear particles according to the second light intensity data and the third light intensity data.

[0087] Since both the blank sample and the metal wear particles will absorb the detection light beam, the second light intensity data reflects the absorption of the detection light beam by the blank sample and the metal wear particles, and the third light intensity data is the light intensity data received by the photodetector when the blank sample alone absorbs the detection light beam. Therefore, the absorption of the detection light beam by the metal wear particles can be determined by combining the second light intensity data and the third light intensity data.

[0088] Figure 9 is the schematic diagram of the sixth operation interface of the detection method provided by the embodiment of the present invention. Refer to Figure 9, after the detection is completed, the interface displays "Restart to use the existing baseline", and currently, the oil sample can be detected again based on this blank baseline. Figure 10 It is the seventh schematic diagram of the operation interface of the detection method provided by the embodiment of the present invention. Figure 11 It is the eighth schematic diagram of the operation interface of the detection method provided by the embodiment of the present invention. Figure 10 and Figure 11 is the interface for detecting again based on this blank baseline.

[0089] For the detection method provided by the embodiment of the present invention, by measuring the third light intensity data, the absorption of the blank sample to the detection beam is determined, and the distribution information of metal wear particles is determined by comprehensively considering the second light intensity data and the third light intensity data, excluding the error caused by the absorption of the blank sample to the detection beam, making the distribution information of the detected metal wear particles more accurate.

[0090] Figure 12 It is the flowchart of another detection method for a ferrograph provided by the embodiment of the present invention. Figure 12 The detection method shown further explains how to accurately obtain the first light intensity data, the second light intensity data, and the third light intensity data on the basis of the above embodiment. Refer to Figure 12 , the detection method includes:

[0091] S301. Extract a blank sample and control the blank sample to enter the detection area.

[0092] S302. When the change rate of the third light intensity data within the third preset time length is less than the third preset change rate, receive the third light intensity data.

[0093] The third preset time length is the time length used to check whether the value of the third light intensity data is stable, and the third preset change rate is the change rate used to check whether the value of the third light intensity data is stable. When the change rate of the third light intensity data within the third preset time length is less than the third preset change rate, it indicates that the change of the third light intensity data is small within a certain time, that is, the blank sample has completely filled the detection area, and the transmittance within the detection area basically no longer changes. At this time, the third light intensity data can better reflect the absorption of the blank sample to the detection beam.

[0094] S303. Extract an oil sample and control the metal wear particles in the oil sample to be adsorbed in the detection area.

[0095] S304. After the change rate of the first light intensity data within the first preset time length is less than the first preset change rate, receive the first light intensity data.

[0096] The first preset time length is the time length for checking whether the value of the first light intensity data is stable, and the first preset change rate is the change rate for checking whether the value of the first light intensity data is stable. When the change rate of the first light intensity data within the first preset time length is less than the first preset change rate, it indicates that the oil sample completely fills the detection area, and the transmittance within the detection area basically no longer changes. At this time, the third light intensity data can better reflect the absorption of the detection beam by the oil sample.

[0097] S305. If the first light intensity data is greater than or equal to the first preset data, after the extraction of the oil sample is completed, a blank sample is extracted and the blank sample is controlled to enter the detection area.

[0098] Among them, the transmittance of the blank sample based on the detection beam is greater than the transmittance of the oil sample based on the detection beam except for metal wear particles.

[0099] S306. After the change rate of the second light intensity data within the second preset time length is less than the second preset change rate, the second light intensity data is received, and the distribution information of metal wear particles is determined according to the second light intensity data and the third light intensity data.

[0100] The second preset time length is the time length for checking whether the value of the second light intensity data is stable, and the second preset change rate is the change rate for checking whether the value of the second light intensity data is stable. When the change rate of the second light intensity data within the second preset time length is less than the second preset change rate, it indicates that the blank sample has basically washed away the oil sample and impurities, and the detection area only includes metal wear particles and the blank sample. At this time, the second light intensity data can better reflect the absorption of the detection beam by the oil sample.

[0101] The detection method provided by the embodiment of the present invention can accurately determine whether the first light intensity data, the second light intensity data, and the third light intensity data are in a stable state by detecting the change rates of the first light intensity data, the second light intensity data, and the third light intensity data within the first time. Receiving the first light intensity data, the second light intensity data, and the third light intensity data after the values of the first light intensity data, the second light intensity data, and the third light intensity data are stable can make the detection result more accurate.

[0102] Figure 13 is a flowchart of another detection method for a ferrograph provided by an embodiment of the present invention. Figure 13 The detection method shown further illustrates how to detect metal wear particles of different particle sizes on the basis of the above embodiment. Refer to Figure 13 , the detection method includes:

[0103] S401. Extract an oil sample and control the metal wear particles in the oil sample to be adsorbed in the detection area.

[0104] S402. After the change rate of the first light intensity data within the first preset time length is less than the first preset change rate, receive the first light intensity data.

[0105] S403. If the first light intensity data is greater than or equal to the first preset data, after the extraction of the oil sample is completed, extract a blank sample and control the blank sample to enter the detection area.

[0106] Among them, the transmittance of the blank sample based on the detection beam is greater than the transmittance of the oil sample (except for metal wear particles) based on the detection beam.

[0107] S404. Receive the second methyl light intensity data of the first light detector based on the detection beam incident on the first detection area and the second ethyl light intensity data of the second light detector based on the detection beam incident on the second detection area.

[0108] Optionally, the light detector includes a first light detector and a second light detector, the detection area includes a first detection area and a second detection area, the first detection area is the deposition area of the first particle size particles, the second detection area is the deposition area of the second particle size particles, the first light detector is arranged in the first detection area, and the second light detector is arranged in the second detection area; the particle size of the first particle size particles is larger than the particle size of the second particle size particles.

[0109] The adsorption forces of metal wear particles with different particle sizes by the magnetic module in the detection area are different. The first particle size particles are larger and the adsorption force on them by the magnetic module is also larger. In the detection area, the first particle size particles will be adsorbed and deposited more quickly, while the second particle size particles are smaller and the adsorption force on them by the magnetic module is also smaller. In the detection area, the second particle size particles are adsorbed and deposited more slowly. Thus, the first particle size particles and the second particle size particles will be deposited at different positions in the detection area. The first particle size particles will be deposited in the first detection area, and the second particle size particles will be deposited in the second detection area. The first light detector can receive the detection beam exiting from the first detection area, thereby obtaining the second methyl light intensity data reflecting the distribution information of the first particle size particles. The second light detector can receive the detection beam exiting from the second detection area, thereby obtaining the second ethyl light intensity data reflecting the distribution information of the second particle size particles.

[0110] S405. Determine the distribution information of metal wear particles according to the second methyl light intensity data and the second ethyl light intensity data.

[0111] The distribution information of the first particle size particles can be determined according to the second methyl light intensity data, and the distribution information of the second particle size particles can be determined according to the second ethyl light intensity data.

[0112] The detection method provided by the embodiments of the present invention utilizes the fact that metal wear particles with different particle sizes are deposited at different positions. A first photodetector and a second photodetector are set to detect particles with a first particle size and particles with a second particle size respectively. According to the obtained second light intensity data of type A and the second light intensity data of type B, the distribution information of particles with a first particle size and particles with a second particle size can be obtained respectively, so as to obtain more accurate distribution information of metal wear particles in the oil sample.

[0113] Figure 14 It is a flowchart of another detection method for a ferrograph provided by the embodiments of the present invention. Figure 14 Based on the above embodiments, the shown detection method further explains the situation where the first light intensity data is less than the first preset data. Refer to Figure 14 , the detection method includes:

[0114] S501. Extract an oil sample and control the metal wear particles in the oil sample to be adsorbed in the detection area.

[0115] S502. Receive the first light intensity data of the photodetector after the detection light beam is incident on the detection area.

[0116] S503. If the first light intensity data is less than the first preset data, determine the distribution information of the metal wear particles according to the first light intensity data.
