According to an embodiment, the above-described expert terminal may include various terminals such as a PDA, a mobile phone, a computer, a tablet, and a server. However, it is not limited thereto.

In the above-described inspection by a skilled expert, parts may be classified by grade according to the following rules. For example, the following rule may refer to grade information classified according to the above-described predetermined criteria.

According to one embodiment, grade A may be a part with no or minimal damage or wear of the part. For example, grade B may be a part with little or moderate damage or wear on the part. For example, a grade C could be a part with moderate to severe damage or wear. For example, the U grade may mean a part that is out of the range of the above-mentioned A, B, or C grade, a part that does not operate as intended by the manufacturer, or a part whose function cannot be tested.

According to an embodiment, in the above-described classification by grade, there may be parts excluded from grade determination. For example, parts with signs of damage/wear that could endanger safety, parts that are not certified, parts that are not original or do not bear the mark of the vehicle/component manufacturer, parts that are not manufactured to the specifications of the vehicle manufacturer, original parts Parts that do not have the same quality/performance or parts that form part of the body structure welded to the vehicle to be dismantled may be excluded from the grade determination. For example, the reuse of such parts also makes the vehicle equipped with such parts unsuitable under the Road Traffic Act, parts that do not pass the test and certification of safety agencies, parts recovered by vehicle recalls by manufacturers/driver inspection agencies, Structural parts that are twisted, bent or deformed, parts that require welding or have severe corrosion such as rust on structural joints, parts that have hail/water damage, cracked or distorted wheels or swollen, split cuts , tire components with cracks, dents, uneven tread wear, exposed plies or cords may be excluded from grading.

According to an embodiment, parts excluded from the above-described grade determination can be quickly identified by a skilled expert, thereby increasing the efficiency of grade determination.

According to an embodiment, the types of parts of the vehicle to be dismantled may be classified into a mechanical part 210, a part 220 that is not sensitive to appearance, a part 230 that is sensitive to appearance, and a battery and high voltage part 240.

According to one embodiment, the mechanical part 210 refers to parts such as an engine, a gearbox, a drive shaft, and the like, and a grade of the parts may be determined according to a driving distance. For example, since the mechanical part 210 is an essential item for driving a vehicle, it may be worn according to a driving distance.

According to one embodiment, the criterion for determining the grade of the mechanical part 210 is that the part operates correctly as intended by the manufacturer, there is no visual damage such as cracks, acoustic damage or malfunction, distortion, oil exposure, contamination. It can be defined as no oil or coolant problems.

According to one embodiment, the grade A of the mechanical component 210 may be a part with a driving distance of less than 100,000 km, the grade B may be a part with a driving distance of 100,000 km to 150,000 km, and the grade C may be a part with a driving distance of 150,000 km. Parts exceeding km, U-class may be parts that cannot be tested or do not meet the manufacturer's operating standards.

According to an embodiment, the appearance-insensitive part 220 is an appearance non-sensitive part and may include parts that cannot be directly seen, such as accommodated in other parts.

For example, parts 220 that are not sensitive to appearance include starter motors, fuel injectors, alternators, radiator cooling fans, anti-lock braking system pumps, air conditioning pumps, windshield wiper motors, parking and other sensors, window regulators, and power steering. This may include pumps, hybrid and electric vehicle drive trains/wheels, motors, engine controls or other electronic controls.

According to one embodiment, the parts 220 that are not sensitive to appearance may be classified as ① parts without driving operation and ② heat exchangers.

Examples of non-driven parts are track control arms, stabilizer bars, subframes, axles, hubs, anti-roll bars, fuel tanks, tow bars, washer bottles, air cleaners/boxes, wheel arch liners, under body shields, bumpers. Reinforcements and chassis repair parts may be included.

For example, a part without a driven piece may mean an item that must not be bent, twisted, cracked, or excessively corroded, or an item that must not damage all mounting points (mounts).

For example, a part without a moving piece must work as intended, so grades B and C in this category may mean items that do not exist.

For example, heat exchangers may refer to radiators and air conditioners. For example, heat exchangers such as radiators and air conditioners may refer to items where cracks, bends, leaks, compression fins or mounting brackets and fixtures must not be damaged.

For example, F-gas (e.g., a gas that can cause greenhouse gases) should not be emitted from the exterior of the system due to fluorescent dye dyeing of air conditioners, and coolant may mean a product that should not be mixed with oil.

According to an embodiment, if the rating criteria for the parts 220 that are not sensitive to the above-described appearance are classified, the A grade may mean that the parts must function as intended by the manufacturer and have a clean and undamaged visual state. For example, B grade can mean an item that functions as intended by the manufacturer, and minor defects in accessory parts are recognized, but cracks in the mount and performance of the bracket should not affect the function, and the safety of the parts should not be affected. For example, a grade C may be an item that must function as intended by the manufacturer, have a certain degree of defects in accessory parts, but must not corrode the surface. For example, Class C could mean the item must be free of cracks, bends, leaks, damage to compressed pipes or fins, excessive corrosion, air conditioner evaporators must not show signs of F-gas leaks, and oil or water contamination. It can mean an item that should not be there. For example, a U grade may mean that the part does not operate as required by the manufacturer and there is a lot of damage to the attached part.

According to one embodiment, the part 230 that is sensitive to appearance is a part that can be directly seen, and may include mainly external parts or interior parts. For example, the parts 230 that are sensitive to appearance may include an exterior body panel, a grill, and a bumper. For example, the appearance-sensitive parts 230 include ① exterior panels and bumper grades, ② light units, ③ exterior mirrors, ④ glass panels, ⑤ wheels, ⑥ partially worn tires, ⑦ interior parts, ⑧ seats, ⑨ appearance-sensitive parts. It can be classified as an electrical component. For example, the parts 230 that are sensitive to appearance may be graded according to the degree of damage or the number of defects expressed as follows.

For example ① A grade of exterior panel and bumper grade has no surface scratches and scuffs, small scratches, scrapes or gouges, no swage line damage, no mounting damage/fixing bracket, no integral damage, no three-dimensional texture damage, cracks or It may mean a grade that does not correspond to all of the conditions classified as no hole. For example, ① B grade of the external panel and bumper grade may be a grade corresponding to 1 or 2 of the above-mentioned A grade conditions. For example, ① The C grade of the external panel and bumper grade may be a grade corresponding to more than two of the above-mentioned A grade conditions. For example, ① The U grade of the external panel and bumper grade may be a grade corresponding to more than three of the above-mentioned A grade conditions.

For example, the lighting device of the ② light unit may include front and/or back lighting, and the lighting device may be graded according to a visual inspection and the following criteria. For example, if you classify front and rear lighting units, a class A would mean that all seals and mounting brackets are intact and not dimmed, there is no internal moisture or corrosion, they operate on principle as intended by the electronic component/sensor manufacturer, and all It can mean a permanently attached mounting, almost equivalent to an OEM new product with undamaged hardware. A grade of B, for example, includes visual defects, electronics/sensors working as intended as intended by the manufacturer, permanently affixed mounting hardware undamaged, and undamaged light units to lower quality, light surfaces. It may mean that there is some damage. For example, a grade of C could mean minor repairs are needed, the lens is cloudy, the mount is damaged, or the light surface is damaged. For example, a U grade may mean a case in which an auxiliary electronic component/sensor does not operate as intended by a manufacturer, or a case in which an electronic test component/sensor does not operate during a test.

For example, ③ exterior mirrors may include door mirrors and wing mirrors, and exterior mirror grades may be classified according to the following criteria. For example, Grade A is equivalent to OEM-new quality, where OEM parts, bodies, covers, and glass are not cloudy, dented, chipped, or cracked, and electronic/sensor mechanical components operate as intended by the manufacturer. If it works and the attached mount hardware is undamaged, it may mean that minor cosmetic damage can be repaired with polishing and buffing. For example, Class B means that the body, cover, and glass are not fogged, are free of dents, chips, or cracks, and that the electronic/sensor mechanical components operate as intended by the manufacturer, all with permanently attached mounting hardware. It may mean a non-damaged case, that is, a case where there is no damage and some repair work is required. For example, grade C may mean that the body, cover, and glass are of lower quality than grade A or B, but can be used with minor repairs, or that the overall quality is low, but repairs are possible with all functions working. For example, a U grade may mean a case in which an electronic component/sensor does not operate.

For example, ④ glass panels may include windshield, sunroof, door and tailgate glass, and may be classified according to the following criteria. For example, Grade A means that the glass is not cloudy, has no dents, chips, cracks, scratches, associated electronics and motors are in good working order, and all mounts are undamaged. It can mean the same quality as an OEM new part. For example, a B rating might mean that the mounting hardware is intact and undamaged, the glass is not broken and cracked, there are no safety defects, the associated motors or electrical components are working normally, and some damage is present. For example, grade C may mean that the glass is not broken and there are some cracks, but there are no structural defects, so there is no safety problem. Electronics and motors are not functioning, which may mean that some damage exists.

For example, ⑤ wheels can be graded in the same way as body panels according to the following criteria (damage unit basis). For example, any damage must not affect the structural integrity or compromise the safety of the wheel, and anything outside of Class A, B or C may not be classified as Class U and may be discarded. For example, a grade of A could mean undamaged, no minor visual blemishes/defects found, and could mean a condition similar to that of a new OEM product. For example, grade B may mean that there are no more than 1-2 light curves, scratches, lacquer or corrosion. For example, a grade of C could mean a quality where there are two or more light curves, blemishes, lacquer surfaces, or corrosion and require minor balance corrections.

For example, ⑥ partially worn tires can be classified as follows. Partially worn tires must be less than 10 years old, and partially worn tires outside of A and B grades may be scrapped. Grade A may mean a tire bone depth of 5 to 8 mm, and B grade may mean a tire bone depth of 3 to 5 mm. Also, tires with worn plies or cords exposed to swelling, cracks, cuts, cracks or uneven tread wear, loss or deterioration of the tire structure may be classified as unusable.

For example, ⑦ Interior parts include interior trim panels, trays, dashboards, steering wheels, carpets and headliners, but electrical parts may be excluded. For example, a grade of A is any visual that is clean and unimpaired, quality that is not compromised. It can mean the quality of OEM new parts. For example, grade B is not structurally damaged, but the damaged quality of a weak acid. It can mean some marks or stains, bolts, motors, etc. that are functioning normally. For example, grade C may mean quality with moderate problems without damage to the existing structure, or quality with damage but no problems with structural use. For example, a U grade may mean a case of severe damage.

For example, ⑧ seats can be classified according to the following criteria. For example, an A grade could mean the same quality as a new OEM product, clean and undamaged visuals, frame undamaged and all motors and related parts in good working order. For example, grade B is not structurally damaged, but has a minor damaged quality. It could mean liver damage, bolts, or motors not working quality. For example, a grade C could mean worn and damaged fabrics, leather upholstery, etc., where structurally undamaged but moderate/major imperfections or wear/scratches are present. For example, a U rating could mean serious quality problems, severe stains, damage, bolts, motors, and related parts not working.

For example, ⑨ Appearance-sensitive electrical components include dashboard switches, door switches, column switches, ignition switches, steering wheel switches, audio and infotainment devices, satellite navigation systems, rear sensors, cameras, heater controls, instrument panels, heater fans, It may include alarm and eCall systems, etc. For example, an A rating might mean the same quality as a new OEM product, functioning as intended by the manufacturer, and having clean, undamaged visuals. For example, a grade B could mean that the device works as intended by the manufacturer and has minor damage. For example, a grade of C could mean that the device works as intended by the manufacturer and has moderate damage. For example, a U grade may mean a case in which a component does not operate as intended by the manufacturer and does not operate normally.

According to an embodiment, the battery and high voltage component 240 may be classified into ① a lead acid battery, ② a high voltage battery, and ③ a high voltage component other than a battery.

For example: (1) For lead-acid batteries, the casing and terminals must be completely undamaged, there must be no signs of electrolyte leakage and no damage, and the battery must operate as originally intended by the manufacturer. For example, a rating of A might be when the cover case and terminals are completely intact, the acidity is normal with no leaks, and it is working as intended by the manufacturer.

For example, ② high voltage batteries may include lithium ion and nickel cadmium batteries. For example, a high-voltage battery must have its cover case and electrical connections completely intact and undamaged, and the battery must operate as intended by the manufacturer. For example, high-voltage batteries must not be affected by water or fire, and a full vehicle scan must be completed before disassembling the vehicle. It should also record the battery, battery state of charge, and individual cell/module readings. For example, a high-voltage battery must also complete a 'run test' to ensure that the assembly functions as intended and as the manufacturer intended. For example, A grade may mean a case in which it is used for less than 100,000 km, B grade in a case where it is used between 100,000 and 150,000 km, and C grade may mean a case in which it is used for more than 150,000 km.

For example, ③ high-voltage parts other than batteries include high-voltage inverters, converters, air conditioner pumps, and electric motors, and may also include electric motors of high-voltage vehicles and entire transmission packs. The cover case and electrical connections are required to be completely undamaged, functioning as intended by the manufacturer, and free from impact, water or fire damage. In addition, a 'run test' must be completed to ensure that the assembly performs as originally intended, according to the manufacturer's criteria. For example, A grade may mean a case of use of less than 100,000 km. For example, B grade may mean a case of use between 100,000 and 150,000 km. For example, the C grade may mean a case of use exceeding 150,000 km.

According to an embodiment, the above-described classification criteria and grades may be determined by a skilled expert in determining parts of a vehicle to be dismantled, and the expert may transmit the above-described classification and grade of the parts to a server through an expert terminal.

According to an embodiment, the server may store received information on the type and grade of parts of the vehicle to be dismantled in a DB or memory.

In the step of assigning a grade according to the result learned by the artificial neural network using the multi-viewpoint image received from the seller terminal as learning material (S130), the artificial neural network based on the multi-viewpoint image of the vehicle part to be dismantled received from the seller This is the step of assigning a grade according to the learning result.

According to an embodiment, the above-described multi-viewpoint image may refer to an image photographed in various ways with respect to vehicle parts to be dismantled from a seller. For example, the multi-viewpoint image may be a six-sided image including front, rear, left, right, top, and bottom images of the dismantled vehicle part.

According to an embodiment, the server matches and stores the identifier of the part of the vehicle to be dismantled, the identifier of the vehicle equipped with the component to be dismantled, and the vehicle identification number of the vehicle equipped with the component to be dismantled together with the multi-view image. can

According to an embodiment, the multi-viewpoint image described above may be stored in a server and posted on a used car parts trading platform. For example, the multi-viewpoint image described above may be referred to when a buyer purchases a part through a buyer's terminal.

According to an embodiment, the multi-faceted image described above may be used as learning information data of an artificial neural network (artificial intelligence, AI). For example, artificial neural networks may include artificial neural networks (ANNs), convolution neural networks (CNNs), and recurrent neural networks (RNNs).

According to an embodiment, since the artificial neural network is learned through the above-described multi-viewpoint image, it is possible to increase the accuracy of determining part grade information of the vehicle to be dismantled using the multi-viewpoint image as input data.

According to an embodiment, since identifiers are assigned to each of the vehicle to be dismantled and the parts of the vehicle to be dismantled, the artificial neural network can increase the effect of learning using multi-view images as input data.

According to an embodiment, the grade information reacquisition step (S140) of reacquiring the grade information may be a step of obtaining grade information again by comparing the grade according to the grade given by the above-described expert and the grade determination result by the artificial neural network. there is.

According to an embodiment, the component grade information of the vehicle to be dismantled received from the expert terminal may be different from the grade information of the vehicle to be dismantled determined by the artificial neural network based on the multi-view image of the vehicle component to be dismantled. For example, the grade information of the vehicle parts to be dismantled received from the above-described expert terminal may be A grade, but the grade information of the parts determined by the artificial neural network based on the multi-view image of the vehicle parts to be dismantled may be B grade. For example, in the above example, there is a difference of 1 grade in the A, B, C, and U grades for parts. All of the rating information can be posted on the used car parts trading platform. In the above example, the purchaser can purchase vehicle parts using the above two types of grade information as judgment data.

According to an embodiment, the grade information of the vehicle part to be dismantled received from the above-described expert terminal may be A grade, but the grade information of the part determined by the artificial neural network based on the multi-view image of the vehicle part to be dismantled may be C grade. . For example, in the above example, since there is a difference of 2 grades in grades A, B, C, and U for parts, in this example, the server can acquire the grade information of the vehicle parts to be dismantled again. For example, the rating information reacquisition step (S140) of reacquiring the rating information for the part is a step of re-requesting the rating information determination of the part to the expert terminal or re-assigning the rating information determination of the part using an artificial neural network. It may be a step of reacquiring grade information of vehicle parts to be dismantled through any one of them.

According to an embodiment, the above-described expert may receive the above-described re-request for rating information determination through an expert terminal and assign a rating again. For example, the artificial neural network can be learned using grade information previously determined by an expert, that is, grade information in the step of receiving grade information, as input data, and can again assign a grade to parts according to the result of machine learning.

According to an embodiment, a difference of more than a certain standard for reacquiring grade information of a vehicle part to be dismantled may mean a case in which a difference of 2 or more grades appears among the above-described grades A, B, C, and U.

According to an embodiment, the server may post only one grade among two types of grade information that may be acquired in the above-described grade information reacquisition step on the used car parts trading platform.

According to an embodiment, the server transmits parts to an expert terminal until a difference between the two types of grade information that can be obtained in the above-described grade information reacquisition step does not occur, that is, until the above-mentioned two types of grades match. A step of re-requesting the rating information determination or re-assigning the rating information determination of the part using an artificial neural network may be executed.

Upon receiving the information provision request from the purchaser terminal, the information providing step (S150) of displaying the information on the requested part is a step in which the server posts information on the part to the platform in response to the purchaser's parts search.

According to an embodiment, when a buyer searches for vehicle parts to be dismantled, a server providing a used car parts trading platform may post parts functionally related to the searched parts on the platform.

For example, the server may list parts of the same type that differ by less than a certain amount from the part the buyer was searching for. The above-mentioned predetermined amount may be determined in advance by the server. For example, the server may post similar parts having information similar to the weight, dimensions, and performance of the part searched for by the purchaser based on information such as weight, size, and performance. The server may store data related to the weight, dimensions, and performance of various types of automobile parts in a DB or in memory so that similar parts may be posted.

The step of storing the transaction information of the sold product (S160) is a step of storing the information about the sale if the sale is made.

According to an embodiment, when a vehicle part to be dismantled is sold, an identifier number and vehicle identification number of the corresponding vehicle and identifier number information of the vehicle part may be stored in a server.

According to an embodiment, when a sale is made, information on the sale price and date may be stored in the server. For example, the sales information described above may be stored in the server for at least two years.

According to an embodiment, the product may be guaranteed for a certain period from the date of sale by storing the date of sale. For example, 3 months for mechanically covered parts, 3 months for electrically covered parts, 12 months for non-mechanically and non-electrically covered parts (e.g. excluding partially worn tires), 3 months for partially worn tires, batteries and high voltage parts.
