Description

Technical Field

[0001] The present invention relates to the technical field of chemical engineering, and in particular, to a method and system for adding phosphating solution, a storage medium, and an intelligent terminal. Background Art

[0002] Phosphating solution is a chemical solution widely used in metal surface treatment, mainly used to improve the corrosion resistance, wear resistance, lubricity, and painting adhesion of metals. By immersing the metal to be processed in the phosphating solution, a reaction occurs between the metal to be processed and the phosphating solution, thereby performing phosphating treatment on the metal.

[0003] In the prior art, when chemical enterprises perform phosphating treatment on metals, they usually pre-prepare phosphating solutions with concentrations matching the metals to be processed. When preparing the phosphating solution, the equipment extracts materials from multiple drums storing phosphating solution components according to the processing requirements of the metal. When the materials in the drum are insufficient, materials need to be replenished.

[0004] During the process of replenishing materials, the operator pours the container filled with materials into the drum. During the pouring process, due to the operator's negligence, the component materials of the phosphating solution are likely to leak to the ground, thereby causing corrosion of the ground. Summary of the Invention

[0005] The present invention provides a method and system for adding phosphating solution, a storage medium, and an intelligent terminal to avoid the problem that when replenishing materials for the phosphating solution, the component materials of the phosphating solution leak to the ground, thereby causing corrosion of the ground.

[0006] In a first aspect, the present invention provides a method for adding phosphating solution, adopting the following technical solution:

[0007] A method for adding phosphating solution includes:

[0008] Obtaining an image of the standing position of a person in the raw material pool area;

[0009] Determining whether a preset charging drum feature exists in the standing position image;

[0010] If not, continue to detect whether the charging drum feature exists;

[0011] If it exists, analyze the side type of the person holding the charging drum from a preset posture database according to the standing position image;

[0012] Determine the acquisition position according to the side type;

[0013] Based on the acquisition position, obtain the ground image information at the edge of the charging drum;

[0014] Determine whether the ground image information is consistent with a preset ground feature;

[0015] If they are consistent, the detection is completed;

[0016] If they are inconsistent, frame out the abnormal features and the abnormal coordinate set from the ground image information;

[0017] Control the preset cleaning device to clean the abnormal features according to the abnormal coordinate set.

[0018] By adopting the above technical solution, the system can analyze the side posture of the personnel to control the cameras that meet the requirements to obtain images of the feeding bucket and the ground beside the feeding bucket. The system can analyze the abnormal features from the ground image information so as to process the abnormal features. Since the system can obtain images in real time, when the personnel supplement raw materials through the feeding bucket and accidentally leak the raw materials on the ground, the system can clean the raw materials on the ground in time, avoid the ground from being corroded, with relatively high efficiency and improved safety.

[0019] Optionally, the cleaning device includes a drying device and a suction device. The method for identifying and processing abnormal features includes:

[0020] Obtain regional image information in the raw material pool area;

[0021] Output the standing position image or the unoccupied position image according to the comparison between the regional image information and the personnel features;

[0022] Continue the detection based on the standing position image;

[0023] Based on the unoccupied position image, obtain the color information of the abnormal features;

[0024] Determine the water stain features or raw material features according to the comparison between the color information and the preset potion color;

[0025] Based on the water stain features, control the drying device to dry the water stain features;

[0026] Based on the raw material features, control the suction device to suck and recycle the raw material features, and obtain the residual area value of the ground at the abnormal coordinate set after recycling;

[0027] Match the corresponding neutralizing solution according to the residual area value;

[0028] Control the preset spraying device to spray the neutralizing solution on the ground at the abnormal coordinate set according to the area value, and dry the ground at the abnormal coordinate set through the drying device.

[0029] By adopting the above technical solution, the system can determine whether to handle foreign objects by judging whether there are people in the raw material pool area, so that it is not easy to pose a danger to people when the system controls the equipment to clean foreign objects. And when the system is handling foreign objects, it can judge the type of foreign objects according to the color of the foreign objects, so as to generate corresponding solutions, thereby improving the efficiency and effect of handling foreign objects, and it is not easy for foreign objects to remain.

[0030] Optionally, the drying method of the drying device includes:

[0031] Generate the outer contour information of the water stain feature according to the abnormal coordinate set;

[0032] Generate a drying path according to the outer contour information and the preset spiral path database;

[0033] Control the drying device to wipe the water stain feature according to the drying path, and obtain the humidity detection value of the wiping surface of the drying device;

[0034] Judge whether the humidity detection value is greater than the preset reference humidity value;

[0035] If it is not greater, continue to wipe the water stain feature and control the preset wind power device to suck water from the wiping surface with the preset sucking force;

[0036] If it is greater, switch to the preset preparatory wiping surface to continue wiping the water stain feature, place the wiping surface in the preset water recovery device, control the preset wind power device to blow air on it with the preset blowing force, and control the water recovery device to heat and dry synchronously.

[0037] By adopting the above technical solution, when the drying device wipes the ground through the wiping surface, the system can detect the humidity of the wiping surface. When the humidity of the wiping surface is high, the wiping surface can be switched, so that the wiping surface can always be relatively dry, so as to ensure that when the wiping surface wipes the ground, the ground can be wiped clean and it is not easy to have residues. And the system can control the wind power device and the water recovery device to control and dry the humidity of the wiping surface at all times, so that the humidity speed of the wiping surface is reduced and there is always a preparatory wiping surface available for replacement with the wiping surface, and the efficiency is relatively high.

[0038] Optionally, there are multiple water recovery devices, and each water recovery device has a preparatory wiping surface. The wind power device has a first air duct state and a second air duct state. The switching method between the wiping surface and the preparatory wiping surface includes:

[0039] Obtain the preparatory surface humidity value of the preparatory wiping surface in the water recovery device;

[0040] Determine whether the preparatory wiping surface is a switchable type or a non-switchable type according to the comparison relationship between the preparatory surface humidity value and the preset cavity humidity value;

[0041] Determine whether the humidity detection value of the wiping surface is greater than the reference humidity value;

[0042] If it is not greater, and based on the switchable type, control the wind power device to be in the second air duct state, and suck the moisture on the wiping surface through the suction force and send it to a preset water storage tank;

[0043] If it is not greater, and based on the non-switchable type, control the wind power device to be in the first air duct state to connect the wiping surface and the preparatory wiping surface;

[0044] If it is greater, and based on the switchable type, control the wind power device to be in the first air duct state, control the preset manipulator to unlock the wiping surface and the preparatory wiping surface, and switch the preparatory wiping surface with the wiping surface, and record the current position of the wiping surface on the ground at the same time;

[0045] Control the wind power device to blow air in the reverse direction and fix the water stain characteristics at the current position. After the preparatory wiping surface is switched, return to the current position and re-suck the water stain characteristics, and continue to move along the drying path;

[0046] If it is greater, and based on the non-switchable type, obtain a preset preparatory water recovery device whose preparatory surface humidity value is less than the cavity humidity value, and control the manipulator to switch the wiping surface with the preparatory wiping surface in the preparatory water recovery device.

[0047] By adopting the above technical solutions, by setting multiple water recovery devices, and the water recovery device has two air duct states, the system can detect the humidity of the wiping surface and the preparatory wiping surface to generate multiple control schemes for the wiping surface, so that the wiping efficiency of the drying device on the ground is relatively high.

[0048] Optionally, the suction device includes a scraper, a suction pipe and a blowing head. The suction pipe is connected to the end of the scraper. The suction recovery method of the suction device includes:

[0049] Generate the edge contour information of the raw material features according to the abnormal coordinate set;

[0050] Determine the scraping direction, scraping position of the scraper and the blowing position of the blowing head according to the edge contour information and the preset suction docking position;

[0051] Generate a blowing path on both sides of the blowing position according to the blowing position and the edge contour information at the blowing position;

[0052] Determine the blowing force of the blowing head according to the scraping position and the blowing position;

[0053] Based on the scraping direction and scraping position, control the scraper to scrape the raw material features, control the blowing head to move along the blowing path and gather the raw material features to the central position, and control the blowing head to blow the raw material features towards the scraper based on the blowing force, and at the same time obtain the rising height of the raw material features on the scraper;

[0054] Match the corresponding liquid suction force of the suction pipe according to the rising height;

[0055] Based on the suction force, control the suction pipe to suck the raw material characteristics.

[0056] By adopting the above technical solution, the raw material characteristics are scraped by the scraper, and the raw materials can be concentrated and sucked by the suction pipe relatively quickly. At the same time, the raw materials are blown by the blowing head, and the blowing head can ensure that the raw materials are gathered and pushed towards the suction pipe, so that the suction pipe can suck the raw materials faster, thereby improving the processing efficiency of the raw materials.

[0057] Optionally, the filtering method of the recovered raw material characteristics includes:

[0058] Obtain the layered image information of the raw material characteristics after standing in the preset recovery box;

[0059] Match the layered image information with the preset feature recognition library to obtain the oil stain feature and the impurity feature;

[0060] Based on the oil stain feature, obtain the oil stain image information of the oil stain feature;

[0061] Determine the oil stain position and the oil stain distribution pattern of the oil stain feature on the surface of the raw material characteristics according to the oil stain image information;

[0062] Cut out the preset oil absorbent paper according to the oil stain distribution pattern;

[0063] Control the oil absorbent paper to be laid on the oil stain position to absorb the oil stain, and re-obtain the oil stain image information and match the corresponding absorbent paper until the oil stain feature is 0;

[0064] Based on the impurity feature, obtain the liquid level height of the raw material characteristics and the sinking height of the impurity feature;

[0065] Control the preset straw to extract the raw material characteristics at the position of the liquid level height, and as the raw material characteristics decrease, the position of the straw drops to the sinking height along with the liquid level height.

[0066] By adopting the above technical solution, the stratification phenomenon generated by the raw material characteristics, the oil stain characteristics and the characteristics of solid impurities is utilized, so that the system can first remove the oil stain on the surface of the raw material by the oil absorbent paper, and then gradually suck the raw material slowly. During the process of sucking the raw material, the solid impurities always precipitate and are not easy to mix with the raw material, so that the finally obtained raw material is relatively clean.

[0067] Optionally, the liquid level control method in the raw material pool includes:

[0068] Obtain the liquid level height value in the raw material pool;

[0069] Determine the overflow state or non - overflow state according to the comparison relationship between the liquid level height value and the preset reference height value;

[0070] Based on the overflow state, the raw material overflows from the raw material pool to a preset spare storage tank;

[0071] In the basically non - overflow state, obtain the spare liquid level height in the spare storage tank;

[0072] Judge whether the spare liquid level height is greater than the preset available height value;

[0073] If it is greater, calculate the difference between the liquid level height value and the reference height value, and define it as the material shortage height;

[0074] Control the raw material to be pumped from the spare storage tank into the raw material pool according to the material shortage height, and update the liquid level height value in the raw material pool until the liquid level height value is consistent with the reference height value;

[0075] If it is not greater, determine whether to continue detection or give a material shortage warning according to the comparison relationship between the liquid level height value and the preset warning height.

[0076] By adopting the above technical solution, the system can perform real - time detection on the raw materials in the raw material pool. When the raw materials in the raw material pool are about to overflow, the system can send the raw materials into the spare storage tank for storage. When the raw materials in the raw material pool are insufficient, the system can control the raw materials in the spare storage tank to supplement the raw material pool, so that the raw materials in the raw material pool always remain at a reasonable height.

[0077] In a second aspect, the present application provides a phosphating solution dosing system, adopting the following technical solution:

[0078] A phosphating solution dosing system, comprising:

[0079] An acquisition module, configured to acquire standing position images, ground image information, regional image information, color information of abnormal features, residual area values, humidity detection values, preliminary surface humidity values, stratification image information, oil stain image information, liquid surface height, bottom sediment height, and liquid level height values;

[0081] A processor, the program in the memory can be loaded and executed by the processor and implement a control method of a phosphating solution dosing method.

[0082] In a third aspect, the present application provides a computer storage medium, which can store a corresponding program and has the characteristic of facilitating the implementation of a phosphating solution dosing method, adopting the following technical solution:

[0083] A computer-readable storage medium stores a computer program that can be loaded and executed by a processor to implement a phosphating solution dosing method.

[0084] In a fourth aspect, the present application provides an intelligent terminal, adopting the following technical solution:

[0085] An intelligent terminal includes a memory and a processor. The memory stores a computer program that can be loaded and executed by the processor to implement a phosphating solution dosing method.

[0086] By adopting the above technical solution, the system can control a compliant camera to capture images of the dosing tank and the ground beside the dosing tank by analyzing the lateral posture of the operator. The system can analyze abnormal features from the ground image information and process the abnormal features. Since the system can obtain images in real time, when the operator replenishes raw materials through the dosing tank and accidentally leaks the raw materials on the ground, the system can promptly clean the raw materials on the ground, avoiding corrosion of the ground, with high efficiency and improved safety.

[0087] In summary, the present application includes at least one of the following beneficial technical effects:

[0088] A phosphating solution dosing method, where the system can detect foreign object features on the ground and process the foreign objects in the absence of personnel on site, making it less likely to pose a danger to personnel during the foreign object handling process;

[0089] By setting multiple moisture recovery devices, and the moisture recovery devices having two air duct states, the system can detect the humidity of the wiping surface and the preparatory wiping surface to generate multiple control schemes for the wiping surface, thereby enabling the wiping device to have a high wiping efficiency for the ground;

[0090] Utilizing the stratification phenomenon generated by the characteristics of raw materials, oil stain characteristics, and solid impurities, the system can first remove the oil stains on the surface of the raw materials with absorbent paper, and then gradually absorb the raw materials. During the process of absorbing the raw materials, the solid impurities always precipitate and are not easily mixed with the raw materials, resulting in relatively clean raw materials finally obtained.

[0100] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0101] The embodiment of the present application discloses a method for adding phosphating liquid.

[0102] Reference Figure 1 A method for adding phosphating solution comprises the following steps:

[0103] S100: Acquire a standing position image of a person in a raw material pool area.

[0104] When the raw material pool is insufficient, personnel need to manually add materials to the raw material pool with a feeding bucket. The standing position image refers to the image of the position where the personnel stand when adding materials to the raw material pool obtained by the camera. The standing position image must contain personnel features.

[0105] S101: Determine whether there is a preset feeding bucket feature in the standing position image.

[0106] There are two situations when a person stands near the raw material pool area: the person holds a charging bucket to add materials or the person does not hold a charging bucket but is simply standing near the raw material pool. Therefore, in order to determine whether the person holds a charging bucket to add materials, the charging bucket features can be matched from the standing position image.

[0107] S1011: If not, continue to detect whether there is a feeding bucket feature.

[0108] Only when a person holds the charging barrel to add materials, the raw materials in the charging barrel may leak to the ground due to inadvertent leakage, so it is necessary to repeatedly detect the charging barrel characteristics until the charging barrel characteristics are detected.

[0109] S1012: If it exists, analyze the side type of the person holding the feeding bucket from the preset posture database according to the standing position image.

[0110] The side type refers to the form of the person holding the feeding bucket. The person may hold the bucket with the left hand or the right hand.

[0111] Due to different side types of the person, the person's body may block the feeding bucket when the camera takes a picture. Therefore, it is necessary to analyze the side type, and the camera takes pictures from the side where the person's body cannot block the feeding bucket.

[0112] The posture database contains the side type postures of the two actions of the person holding the bucket with the left hand and the right hand. It is a database generated by machine learning and will not be elaborated here. The standing position image can be compared with the posture database to determine the side type of the person.

[0113] S10121: Determine the acquisition position according to the side type.

[0114] The acquisition position refers to the position where the camera is installed. In this embodiment, the number of cameras is two, and the two postures of the side type correspond one by one, so that no matter which side type the person is in, the feeding bucket can be photographed by one of the cameras. Select one of the cameras at the installation position through the side type.

[0115] S10122: Based on the acquisition position, obtain the ground image information beside the feeding bucket.

[0116] The ground image information refers to the image of the ground in the area of the feeding bucket. If there is a leakage when the person feeds the material, the leaked raw material can be reflected in the ground image information.

[0117] S10123: Judge whether the ground image information is consistent with the preset ground feature.

[0118] The preset ground feature refers to the image obtained by the camera when the ground is clean. At this time, there is no leaked raw material on the ground in the image. By judging whether the ground image information is consistent with the ground feature, it is determined whether there is leaked raw material on the ground.

[0119] S101231: If they are consistent, the detection is completed.

[0120] If the result judged by the system is consistent, it means that there is no leaked raw material on the ground and the ground does not need to be processed.

[0121] S101232: If they are inconsistent, frame out the abnormal features and the abnormal coordinate set from the ground image information.

[0122] If the result judged by the system is inconsistent, it indicates that there may be leaked raw materials on the ground, that is, there are features in the ground image information that are different from the ground features.

[0123] The abnormal feature is a feature different from the ground feature obtained by comparing the ground image information with the ground feature. This feature may be the leaked raw material or the spilled water stain.

[0124] The abnormal coordinate set is the coordinate set of the abnormal feature on the ground, that is, the position of the abnormal feature on the ground. Taking the position where the camera is located as the origin coordinate, the abnormal coordinate set can be obtained according to the ground image information and the abnormal feature.

[0125] S1012321: Clean the abnormal feature by controlling the preset cleaning device according to the abnormal coordinate set.

[0126] After determining the position of the abnormal feature on the ground, the cleaning device can be controlled to clean it. Different processing methods for different types of abnormal features will be introduced in the subsequent steps and will not be elaborated here.

[0127] Refer to Figure 2 , the cleaning device includes a drying device and a suction device, and the recognition and processing method of the abnormal feature includes the following steps:

[0128] S200: Obtain the area image information in the raw material pool area.

[0129] The area image information refers to the environmental image of the raw material pool area obtained by the camera.

[0130] S201: Output the standing position image or the no-person position image according to the comparison between the area image information and the personnel feature.

[0131] The standing position image has been introduced in step 100. The no-person position image corresponds to the standing position image. The no-person position image refers to the image when there is no person in the raw material pool area.

[0132] The area image information includes the output of the standing position image and the no-person position image. The area image information is compared with the personnel feature. By judging whether there is a personnel feature in the area image information, it can be determined whether the area image information is a standing position image or a no-person position image. When it is found that there is an abnormal feature on the ground in the raw material pool area and needs to be processed, it is necessary to have no person in the raw material pool area before the cleaning equipment can be used for cleaning.

[0133] S202: Continue to detect based on the standing position image.

[0134] When the regional image information is compared with the personnel characteristics and determined to be an image of the standing position, it indicates that there were personnel in the raw material pool area at that time. At this time, the abnormal characteristics cannot be processed, and continuous monitoring is carried out until the regional image information is an image of the unoccupied position.

[0135] S203: Based on the image of the unoccupied position, obtain the color information of the abnormal characteristics.

[0136] When the regional image information is compared with the personnel characteristics and determined to be an image of the unoccupied position, there are no personnel in the raw material pool area at this time.

[0137] By obtaining the color of the abnormal characteristics from the image of the unoccupied position, the types of the abnormal characteristics can be distinguished.

[0138] S204: Determine the water stain characteristics or raw material characteristics according to the comparison between the color information and the preset color of the potion.

[0139] The preset color of the potion refers to the color of the phosphating solution itself, which will not be elaborated here. Since the phosphating solution has a color while the water stain is transparent, by comparing the color information with the color of the potion, it can be determined whether the liquid on the ground is the leaked phosphating solution or the water stain.

[0140] S2041: Based on the water stain characteristics, control the drying device to dry the water stain characteristics.

[0141] If the abnormal characteristics are transparent, directly dry the water stain characteristics through the drying device.

[0142] S2042: Based on the raw material characteristics, control the suction device to suck and recycle the raw material characteristics, and obtain the residual area value of the ground at the abnormal coordinate set after recycling.

[0143] When the abnormal characteristics are the same as the color of the potion, it indicates that the abnormal characteristics on the ground are the phosphating solution. At this time, the leaked phosphating solution is sucked through the suction device, and the sucked phosphating solution can be recycled and reused.

[0144] After the phosphating solution is absorbed, there are still imprints on the ground where the phosphating solution existed. This imprint also has a certain corrosiveness and needs to be treated. The residual area value refers to the area value of the imprint.

[0145] S20421: Match the corresponding neutralizing solution according to the residual area value.

[0146] The neutralizing solution is used to spray on the ground and neutralize the residual imprint of the phosphating solution, so that the pH value of the phosphating solution can become neutral. According to the residual leakage area value, the usage amount of the neutralizing solution can be matched.

[0147] S20422: Control the preset spraying device to spray neutralizing solution on the ground at the abnormal coordinate set, and dry the ground at the abnormal coordinate set through a drying device.

[0148] After the raw material characteristics are cleaned, first spray neutralizing solution on the abnormal feature set on the ground through the spraying device to make the pH of the imprint tend to be neutral, and then dry it with the drying device.

[0149] Refer to Figure 3 , the water stain characteristics are dried through the drying device, and the drying method of the drying device includes the following steps:

[0150] S300: Generate the outer contour information of the water stain characteristics according to the abnormal coordinate set.

[0151] The outer contour information refers to the contour of the water stain characteristics. The outer contour information is formed by combining the outermost coordinate points of the abnormal coordinate set.

[0152] S301: Generate a drying path according to the outer contour information and the preset spiral path database.

[0153] The drying path refers to the moving path of the drying device during the process of drying the water stain by the drying device.

[0154] The preset spiral path database refers to a database that can match and generate a spiral path within the outer contour shape according to the shape parameters of the outer contour, which is a parameter generation database set for technicians and will not be elaborated here. The starting point of the spiral path is at the edge of the outer contour, and its end point is at the center of the outer contour. The shape of the spiral path is spiral.

[0155] The outer contour information can obtain the drying path through the processing of the spiral path database.

[0156] S302: Control the drying device to wipe the water stain characteristics according to the drying path, and obtain the humidity detection value of the wiping surface of the drying device.

[0157] The drying device can move along the drying path, start drying the water stain characteristics from the edge of the water stain, and gradually move along the spiral route to the center of the water stain characteristics.

[0158] The wiping surface of the drying device refers to the component installed on the drying device. The wiping surface contacts the ground and can suck the water stain on the ground into the wiping surface.

[0159] The humidity detection value refers to the humidity value of the wiping surface measured by the humidity sensor when the drying device dries the ground.

[0160] S303: Determine whether the humidity detection value is greater than the preset reference humidity value.

[0161] When the absorbed water stains on the wiping surface reach a certain level, the wiping surface needs to be updated; otherwise, the wiping surface cannot continue to dry the ground. The reference humidity value is the standard for measuring whether the wiping surface needs to be replaced and is a reference value set for technicians, which will not be elaborated here.

[0162] S3031: If it is not greater than, continue to wipe the water stain characteristics and control the preset wind power device with a preset suction force to suck water from the wiping surface.

[0163] If the humidity detection value is not greater than the reference humidity value, it indicates that the wiping surface is relatively dry and can continue to wipe the ground.

[0164] In this embodiment, a wind power device is provided on the drying device. The wind power device has a suction port, and the suction port is connected to the wiping surface. The wind power device can suck air from the suction port to the wiping surface with a preset suction force, so that the wiping surface can be dried while wiping.

[0165] S3032: If it is greater than, switch to a preset preparatory wiping surface to continue wiping the water stain characteristics, place the wiping surface in a preset water recovery device, control the preset wind power device to blow air on it with a preset blowing force, and control the water recovery device to heat and dry synchronously.

[0166] If the humidity detection value is greater than the reference humidity value, at this time, the humidity of the wiping surface is relatively high. Using this wiping surface to wipe the ground cannot dry the ground, and at this time, the wiping surface needs to be replaced.

[0167] In this embodiment, a water recovery device is further provided on the drying device. The water recovery device has a preparatory wiping surface inside. The water recovery device can heat and dry the wiping surface or the preparatory wiping surface. And the wind power device has a blowing port, the blowing port is communicated with the suction port, the blowing port extends into the water recovery device and can be connected to the preparatory wiping surface, and the blowing port can blow air on the preparatory wiping surface with a preset blowing force.

[0168] When the humidity of the wiping surface for wiping the ground is relatively high, the wiping surface can be switched with the preparatory wiping surface through a manipulator, and the relatively dry preparatory wiping surface can continue to wipe the ground, while the wiping surface is placed in the water recovery device for air drying and baking.

[0169] Refer to Figure 4 , in this embodiment, the drying device further has a water storage tank. There are multiple water recovery devices, and each water recovery device has a preparatory wiping surface inside. The wind power device has a first air duct state and a second air duct state. The first air duct state is that the suction port is communicated with the blowing port, and the second air duct state is that the suction port is communicated with the water storage tank.

[0170] The method for switching between the wiping surface and the preparatory wiping surface includes the following steps:

[0171] S400: Obtain the humidity value of the preparatory wiping surface in the moisture recovery device.

[0172] The humidity value of the preparatory surface refers to the humidity value of the preparatory wiping surface when it is in the moisture recovery device.

[0173] S401: Determine whether the preparatory wiping surface is of a switchable type or a non-switchable type according to the comparison relationship between the humidity value of the preparatory surface and the preset humidity value in the cavity.

[0174] The humidity value in the cavity is a standard reference value used to measure whether the preparatory wiping surface is wet in the moisture recovery device and whether it can be switched with the wiping surface. It is a reference value set by technicians and will not be elaborated here.

[0175] If the humidity value of the preparatory surface is greater than the humidity value in the cavity, it is of the non-switchable type. At this time, the preparatory wiping surface in the moisture recovery device cannot be switched with the wet wiping surface.

[0176] If the humidity value of the preparatory surface is not greater than the humidity value in the cavity, it is of the switchable type. At this time, the preparatory wiping surface in the moisture recovery device can be switched with the wet wiping surface.

[0177] S402: Determine whether the humidity detection value of the wiping surface is greater than the reference humidity value.

[0178] When the drying device dries the ground, the humidity detection value of the wiping surface is measured in real time to determine whether the wiping surface needs to be replaced. When the wiping surface needs to be replaced, it is necessary to consider whether the preparatory wiping surface is in a switchable type or a non-switchable type at this time, so as to determine the replacement method of the wiping surface.

[0179] S4021: If the humidity detection value of the wiping surface is not greater than the reference humidity value and based on the switchable type, control the wind power device to be in the second air duct state, and suck the moisture on the wiping surface through the suction force and send it to the preset water storage tank.

[0180] In the first case, if the wiping surface is relatively dry and the preparatory wiping surface in the moisture recovery device is also relatively dry, at this time, switch the air duct of the wind power device to the second air duct state. When in the second air duct state, the suction port is connected to the water storage tank, and the suction port can absorb the moisture on the wiping surface into the water storage tank.

[0181] S40211: If the humidity detection value of the wiping surface is not greater than the reference humidity value and based on the non-switchable type, control the wind power device to be in the first air duct state to connect the wiping surface and the preparatory wiping surface.

[0182] For the second case, if the wiping surface is relatively dry while the preparatory wiping surface in the moisture recovery device is relatively wet, at this time, switch the air duct of the wind power device to the first air duct state. When in the first air duct state, the air blowing port is connected to the preparatory wiping surface of the moisture recovery device, and the air suction port can suck air into the air duct and blow air through the air blowing port to the preparatory wiping surface, so that the preparatory wiping surface can be dried.

[0183] S4022: If the humidity detection value of the wiping surface is greater than the reference humidity value, and based on the switchable type, control the wind power device to be in the first air duct state, control the preset manipulator to unlock the wiping surface and the preparatory wiping surface, and switch the preparatory wiping surface with the wiping surface, and record the current position of the wiping surface on the ground at the same time.

[0184] For the third case, if the wiping surface is relatively wet and needs to be replaced, while the preparatory wiping surface in the moisture recovery device is relatively dry, switch the air duct of the wind power device to the first air duct state. At this time, first unlock the wiping surface and the preparatory wiping surface through the manipulator, and then swap and replace the two. Since the wiping surface is relatively wet when replacing the wiping surface, during the replacement process, part of the water stains fall back to the ground again. Therefore, it is necessary to record the final position of the wiping surface, and wait until the wiping surface replacement is completed and return to the current position to wipe again.

[0185] S40221: Control the wind power device to blow air in the reverse direction and fix the water stain characteristics at the current position. After the preparatory wiping surface switching is completed, return to the current position and re-aspirate the water stain characteristics, and continue to move along the wiping path.

[0186] During the process of replacing the wiping surface and the preparatory wiping surface, change the air duct direction of the wind power device so that the air suction port can blow air to the ground. The air blowing method is that the air suction port sucks air circumferentially along the contour of the water stain characteristics, so that the water stain characteristics can be fixed and will not spread.

[0187] S40222: If the humidity detection value of the wiping surface is greater than the reference humidity value, and based on the non-switchable type, obtain the preset preparatory moisture recovery device with the humidity value of the preparatory surface less than the humidity value in the cavity, and control the manipulator to switch the wiping surface with the preparatory wiping surface in the preparatory moisture recovery device.

[0188] For the fourth case, if the wiping surface is relatively wet and needs to be replaced, while the preparatory wiping surface in the moisture recovery device is also relatively wet and cannot be switched, check the humidity of the preparatory wiping surface in other preparatory moisture recovery devices. If the preparatory wiping surface is in a switchable state, then switch the wiping surface with the preparatory wiping surface in the preparatory moisture recovery device through the manipulator.

[0189] Refer to Figure 5, the suction device includes a scraper, a suction pipe, and a blowing head. The suction pipe is connected to the end of the scraper. The scraper is used to scrape the raw materials on the ground, the suction pipe is used to suck the raw materials on the ground, and the blowing head is used to blow the raw materials towards the suction pipe. The suction recovery method of the suction device includes the following steps:

[0190] S500: Generate the edge contour information of the raw material characteristics according to the abnormal coordinate set.

[0191] When the abnormal feature is a raw material feature, the edge contour information refers to the contour of the raw material feature. The edge contour information is formed by combining the outermost coordinate points of the abnormal coordinate set.

[0192] S501: Determine the scraping direction, scraping position of the scraper, and the blowing position of the blowing head according to the edge contour information and the preset suction docking position.

[0193] The suction docking position refers to the initial placement position of the scraper and the suction pipe in the suction device.

[0194] The scraping direction refers to the path direction for moving the scraper to the nearest point on the edge of the raw material feature. The nearest point on the edge of the raw material feature to the suction docking position is a known parameter, and the scraping direction is the direction from the suction docking position to the nearest point on the edge of the raw material feature.

[0195] The scraping position refers to the position where the scraper starts to scrape after moving into contact with the raw material feature, and this position is the initial contact point between the scraper and the raw material feature.

[0196] The blowing position refers to the direction in which the blowing head blows on the raw material feature. In this embodiment, the blowing position and the scraping position are in the opposite direction of the raw material feature. When the blowing head is at the blowing position, the blowing head can point to the scraping position, so as to blow the raw material feature towards the scraping position.

[0197] S502: Generate blowing paths on both sides of the blowing position according to the blowing position and the edge contour information.

[0198] When the scraper scrapes the raw material feature, the raw material feature will spread out in all directions. In order to prevent the raw material from spreading, the blowing head blows on the periphery of the raw material feature, so as to gather the raw material feature.

[0199] The blowing path refers to the moving path when the blowing head blows on the raw material feature to gather the raw material. In this embodiment, the blowing path extends and unfolds from the edge contour of the feature away from the center of the blowing position to both sides. By blowing on the raw material feature along the blowing path, the blowing head can gather the raw material and also blow the raw material in the scraping direction.

[0200] S503: Determine the blowing force of the blowing head according to the scraping position and the blowing position.

[0201] The blowing force refers to the force when the blowing pipe blows the raw material characteristics towards the scraper direction. Since the distance between the scraping position and the blowing position is changing, and the farther the distance between the two, the greater the blowing force required. Therefore, the blowing force can be determined by the scraping position and the blowing position.

[0202] S504: Control the scraper to scrape the raw material characteristics based on the scraping direction and scraping position, control the blowing head to move along the blowing path and gather the raw material characteristics towards the central position, and control the blowing head to blow the raw material characteristics towards the scraper based on the blowing force, while obtaining the heaving height of the raw material characteristics on the scraper.

[0203] When sucking the raw material characteristics, first scrape the raw material with the scraper, and during the scraping process of the scraper, the blowing head always blows the raw material, making the raw material not easy to disperse and move towards the scraper direction.

[0204] The heaving height refers to the maximum height of the raw material's undulation on the scraper when the scraper blade scrapes the raw material characteristics.

[0205] S505: Match the corresponding liquid suction force of the suction pipe according to the heaving height.

[0206] The liquid suction force refers to the magnitude of the force when the suction pipe sucks away the raw material.

[0207] The greater the heaving height, it indicates that more raw materials are scraped by the scraper. At this time, a greater liquid suction force is required to suck away the heaving raw materials. Therefore, there is a proportional relationship between the heaving height and the liquid suction force, and the liquid suction force can be obtained by matching the heaving height.

[0208] S506: Control the suction pipe to suck the raw material characteristics based on the suction force.

[0209] When the scraper scrapes the raw material characteristics, the blowing head adjusts the blowing position at all times, so that the blowing head and the scraping position are on both sides of the raw material characteristics. When the blowing head blows the raw material towards the suction pipe, the suction pipe sucks away the raw material with the suction force.

[0210] Refer to Figure 6 , after the suction pipe sucks the raw material characteristics, they are all transported to the recycling box. The filtering method of the recycled raw material characteristics includes the following steps:

[0211] S600: Obtain the layered image information of the raw material characteristics after standing still in the preset recycling box.

[0212] The raw material characteristics sucked into the recycling box may include fixed impurities and oil stains. The fixed impurities have a higher density and will sink to the bottom, while the oil stains have a lower density and will float on the top layer of the raw material. When the raw material characteristics stand still, a layering phenomenon will occur. The layered image information refers to the image when the raw material characteristics stand still for a period of time and produce layering.

[0213] S601: Match the hierarchical image information with a preset feature recognition library to obtain oil stain features and impurity features.

[0214] The feature recognition library is used to identify other features in the raw material features, which includes feature images of oil stains and solid impurities. The feature recognition library is obtained through machine learning and will not be elaborated here.

[0215] S6011: Based on the oil stain features, obtain the oil stain image information of the oil stain features.

[0216] When processing the oil stain features, first obtain the oil stain image information of the oil stain features. The oil stain image information is the image of the surface of the raw material in the recycling bin.

[0217] S60111: Determine the oil stain position and the oil stain distribution pattern of the oil stain features on the surface of the raw material features according to the oil stain image information.

[0218] The oil stain position refers to the position of the oil stain features on the surface of the raw material. The oil stain distribution pattern refers to the shape of the oil stain.

[0219] Both the oil stain position and the oil stain distribution pattern can be directly identified and obtained from the oil stain image information.

[0220] S60112: Cut out a preset oil-absorbing paper according to the oil stain distribution pattern.

[0221] The oil-absorbing paper is used to absorb the oil stain. The oil-absorbing paper is cut according to the shape of the oil stain so that the oil-absorbing paper can exactly absorb the oil stain.

[0222] S60113: Control the oil-absorbing paper to be laid on the oil stain position to absorb the oil stain, and re-obtain the oil stain image information and match the corresponding absorbent paper until the oil stain features are 0.

[0223] Lay the cut oil-absorbing paper flat on the oil stain position on the surface of the raw material. After the oil-absorbing paper absorbs the oil stain for a period of time, take out the oil-absorbing paper. At this time, re-detect whether there is still oil stain. If there is still oil stain, continue to process the oil stain until the oil stain is completely removed.

[0224] S6012: Based on the impurity features, obtain the liquid level height of the raw material features and the sinking height of the impurity features.

[0225] After the oil stain features are removed, only fixed impurities and raw materials remain in the recycling bin. The liquid level height refers to the water level height of the raw material in the recycling bin. The sinking height refers to the height of the fixed impurities at the bottom of the recycling bin after standing still.

[0226] S60121: Control a preset straw to extract the raw material features at the position of the liquid level height, and as the raw material features decrease, the position of the straw drops to the sinking height along with the liquid level height.

[0227] After removing the oil stains, since the surface of the raw material is not covered by oil stains, the raw material can be directly extracted through a straw. When the straw extracts the raw material, the straw is always located at the liquid level position of the raw material for extraction. When the liquid level height decreases as the straw extracts, the height of the straw also decreases accordingly. Eventually, when the liquid level height is the same as the bottom height, the straw stops extracting, and the remaining raw material and solid characteristics are discarded.

[0228] Refer to Figure 7 , the liquid level control method in the raw material pool includes:

[0229] S700: Obtain the liquid level height value in the raw material pool;

[0230] The liquid level height value refers to the liquid level height of the raw material in the raw material pool.

[0231] S701: Determine the overflow state or non - overflow state according to the comparison relationship between the liquid level height value and the preset reference height value;

[0232] The reference height value is a reference value used to measure whether the raw material in the raw material pool will overflow, which will not be elaborated here. An overflow port is opened at the position of the reference height value in the raw material pool, and the overflow port is connected to a spare storage tank on one side. The spare storage tank can be used to store the overflowed raw material.

[0233] When the liquid level height value is greater than the reference height value, the raw material pool is in an overflow state. At this time, the raw material in the raw material pool can enter the spare storage tank from the overflow port.

[0234] When the liquid level height value is not greater than the reference height value, the raw material pool is in a non - overflow state. At this time, the raw material in the raw material pool may be less and needs to be refilled.

[0235] S7011: Based on the overflow state, the raw material overflows from the raw material pool to the preset spare storage tank;

[0236] If the raw material pool is in an overflow state, the raw material can enter the spare storage tank for storage.

[0237] S7012: Based on the non - overflow state, obtain the spare liquid level height in the spare storage tank;

[0238] The spare liquid level height refers to the liquid level height of the raw material in the storage tank.

[0239] S7013: Judge whether the spare liquid level height is greater than the preset available height value;

[0240] The available height value is a reference value used to measure whether the raw materials in the spare storage tank can be redrawn into the raw material pool. It is a reference value set by technicians and will not be elaborated here. By comparing the spare liquid level height with the available height value, it is determined whether the raw materials in the spare storage tank are available.

[0241] S70131: If it is greater, calculate the difference between the liquid level height value and the reference height value, and define it as the material shortage height;

[0242] The material shortage height refers to the height at which raw materials need to be replenished into the raw material pool.

[0243] When the spare liquid level height is greater than the available height value, the raw materials in the spare storage tank can be redrawn into the raw material pool. At this time, the amount of raw materials to be drawn from the spare storage tank is determined according to the material shortage height.

[0244] S70132: Control the raw materials to be drawn from the spare storage tank into the raw material pool according to the material shortage height, and update the liquid level height value in the raw material pool until the liquid level height value is consistent with the reference height value;

[0245] During the process of pumping the raw materials from the spare storage tank to the raw material pool through the liquid pumping pump, it is necessary to always obtain the liquid height value to ensure that the raw material pool will not overflow again.

[0246] S70133: If it is not greater, determine whether to continue detection or issue a material shortage alarm according to the comparison relationship between the liquid level height value and the preset warning height.

[0247] The warning height refers to the lowest water level height of the raw materials in the raw material pool. When it is lower than the warning height, raw materials must be replenished into the raw material pool. The warning height is a reference value set by technicians and will not be elaborated here.

[0248] If the spare liquid level height is not greater than the available height value, raw materials cannot be drawn from the spare storage tank at this time. And if the liquid level height value is still greater than the warning height at this time, raw materials can not be replenished into the raw material pool, but the liquid level height value must be monitored in real time. If the liquid level height value is not greater than the warning height, a material shortage alarm will be issued, and at this time, personnel will manually add materials to the raw material pool.
