Description

Technical Field

[0001] This invention relates to the field of air compressors, and more particularly to an air compressor control method, system, storage medium, and terminal. Background Technology

[0002] An air compressor is a mechanical device used to compress gas. Its working principle is mainly based on an electric motor driving a compressor rotor to draw in air, gradually compress it, and finally release the compressed air. In most automated production lines, most pneumatic tools, such as pneumatic wrenches and pneumatic drill bits, use compressed air as their power source; therefore, air compressors have wide applications in various fields.

[0003] Currently, many processing enterprises use air compressor networks consisting of multiple air compressors to meet the air demands of large processing units. When controlling these networks, enterprises typically start all air compressors and simultaneously adjust the air pressure across all units for power regulation. However, air compressors may malfunction after prolonged operation. When controlling air compressors using the above method, if one compressor fails, the overall air pressure output of the air compressor network will not reach the expected setting, thus affecting actual processing and production. This approach needs improvement. Summary of the Invention

[0004] To address the issue of the overall air pressure output of an air compressor network being affected by the failure of a single air compressor, this invention provides an air compressor control method, system, storage medium, and terminal.

[0005] In a first aspect, the present invention provides an air compressor control method, which adopts the following technical solution:

[0006] An air compressor control method, comprising:

[0007] Determine the maximum gas volume required for production activities based on preset operating condition information;

[0008] The number of air compressors to be started in the air compressor network is determined based on the maximum air volume.

[0009] Number the air compressors in the air compressor pipeline network to obtain the device number;

[0010] Based on the number of units to be started, select the corresponding number of air compressors from the device numbers using a preset selection method, and record the start-up time of the air compressors.

[0011] The switching device is determined based on a comparison between the power-on time and the preset baseline switching time;

[0012] Based on the switching device, the air compressor that reaches the reference switching time is controlled to shut down according to the preset rotation method, and the air compressors that have not been started in the air compressor pipeline network are controlled to start.

[0013] By adopting the above technical solution, multiple air compressors are set up to form an air compressor network. A certain number of air compressors are selected from the network to operate based on the maximum air volume, while a portion are kept as backups. After a certain period of operation, the operating air compressors are periodically replaced with the backup air compressors, allowing the air compressors time to rest and reducing the likelihood of malfunctions. Even when an air compressor fails, it can be easily replaced by a backup air compressor, thus not affecting actual processing and production.

[0014] Optionally, when the air compressor starts, the pre-installed dryer in the air compressor pipeline will produce water. Methods for treating the water from the dryer include:

[0015] Obtain the water level in the dryer and the ambient temperature of the air compressor piping network;

[0016] The system determines whether to drain immediately upon overflow or drain at a temperature controlled level based on the comparison between the water level height and the preset drainage height.

[0017] Based on the instant overflow drainage, the water in the dryer is controlled to flow out to a preset water storage tank for storage;

[0018] Based on temperature-controlled drainage, when the ambient temperature falls within the preset high-temperature range, the water in the dryer is controlled to flow out to the preset hot water pipe; when the ambient temperature falls within the preset low-temperature range, the water in the dryer is controlled to flow out to the preset cold water pipe.

[0019] By adopting the above technical solution, the water produced in the dryer can be used in a reasonable way. By taking advantage of the influence of daytime and nighttime ambient temperatures on the water temperature, the daytime ambient temperature can heat the water, while the nighttime ambient temperature can cool the water, thereby preserving the hot water produced during the day and the cold water produced at night for other uses.

[0020] Optional, also includes:

[0021] During air compressor operation, obtain the pipeline air pressure of the air compressor network;

[0022] Determine if the pipeline air pressure is lower than the preset standard air pressure;

[0023] The pipeline air pressure shall be reacquired after a preset processing delay time only if the pipeline air pressure is lower than the standard air pressure.

[0024] The type of low pressure is determined by comparing the pipeline pressure with the standard pressure. Low pressure types include operating low pressure and leakage low pressure.

[0025] Based on the low pressure of the leakage, the location of the leakage point is determined according to the pipeline leakage point location method. The main air valve pre-installed in the air compressor pipeline is closed, and the leakage point is sealed using the leakage point sealing method.

[0026] Optional methods for locating pipeline leaks include:

[0027] The number of infrared cameras to be installed is determined based on the preset recognition range of the infrared cameras and the preset pipe length, and the infrared cameras are numbered to obtain infrared numbers.

[0028] The preset atomizing device connected to the hot water pipe is turned on and the hot water in the hot water pipe is injected into the air compressor pipeline in the form of atomization.

[0029] Control the infrared camera to acquire infrared image information of the pipeline;

[0030] The infrared image information is matched with a preset infrared database to determine the infrared number corresponding to the abnormal camera.

[0031] The location of the leak is determined by matching the infrared number with the corresponding infrared camera that identifies the pipeline, and by matching the infrared image information with the infrared database.

[0032] By adopting the above technical solution, the infrared camera can detect heat. By introducing hot water generated by the dryer into the air compressor pipeline, the air in the air compressor pipeline can become hot, so that the air leaking from the pipeline leak point has a certain amount of heat, which can be detected by the infrared camera. The above method is convenient for locating the leak point.

[0033] Optional methods for sealing leaks include:

[0034] Obtain image information of the leak point location;

[0035] Determine the area of ​​the leak point and the material information of the pipe based on the image information of the leak point;

[0036] The type of plugging is determined by comparing the pipe material information with a preset reference material. The types of plugging include metal plugging and plastic plugging.

[0037] Based on metal plugging, determine whether the area of ​​the leak point is smaller than the preset benchmark plugging area;

[0038] If and only if the area of ​​the leak point is smaller than the reference sealing area, match the corresponding reaming drill bit according to the area of ​​the leak point, control the reaming drill bit to ream the leak point location, reacquire the leak point image information at the leak point location and determine the reaming point outline;

[0039] Match the corresponding sealing column according to the leak point contour, control the sealing column to extend into the leak point position, and control the preset welding device to weld and reinforce along the leak point contour.

[0040] By adopting the above technical solution, when the air compressor pipeline is made of metal and the area of ​​the leak point is small, the leak point can be enlarged to create a hole large enough for a sealing post to be inserted. The sealing post is then welded to the pipeline using a welding device. This method effectively seals the leak, and the sealing post is less likely to be pushed out of the leak point by air pressure. Furthermore, because the sealing post has a small diameter, it is less likely to cause blockage in the pipeline after insertion.

[0041] Optionally, when the area of ​​the leak point is not less than the reference sealing area, the sealing methods at the leak point location include:

[0042] Determine the outline information of the leak point based on the image information of the leak point;

[0043] Generate a cutting path based on the leak point contour information;

[0044] According to the cutting path, the preset cutting device cuts a sealing plate on the preset metal plate that matches the outline information of the leakage point.

[0045] The control welding device welds the sealing plate to the preset metal strip, and controls the sealing plate to be embedded in it according to the location of the leak point;

[0046] Based on the preset pipe cross-sectional profile, the preset bending device bends the metal strip to fit against the outer wall of the pipe and presses the sealing plate tightly at the leak point.

[0047] By adopting the above technical solution, when the area of ​​the leak point is large, a sealing plate that matches the outline of the leak point can be cut out by a cutting device. After the sealing plate is embedded in the location of the leak point, a metal strip is bent into the shape of a pipe to press the sealing plate tightly against the leak point. The above method can be applied to situations where the area of ​​the leak point is large. The sealing plate does not need to extend into the pipe, and it is not easy to cause blockage to the pipe.

[0048] Alternatively, plastic sealing methods include:

[0049] Based on plastic sealing, the outline information of the leak point is determined according to the image information of the leak point;

[0050] The plastic contour information of the preset sealing plastic sheet is determined based on the leakage point contour information;

[0051] Based on the plastic outline information, the preset hot-melt device is controlled to hot-melt the preset plastic sheet to obtain a sealing plastic sheet after edge hot-melt.

[0052] Control the embedding position of the sealing plastic sheet at the leak point to heat-melt the edge of the sealing plastic sheet to the edge of the leak point;

[0053] The cold water pipe is controlled to spray water for cooling based on the outline information of the leak point.

[0054] By adopting the above technical solution, if the pipe is made of plastic, a sealing plastic sheet with the same outline as the leak point can be heat-fused to the leak point to repair the pipe, which is relatively convenient.

[0055] Secondly, this application provides an air compressor control system, which adopts the following technical solution:

[0056] An air compressor control system, comprising:

[0057] The acquisition module is used to acquire the water level in the dryer, the ambient temperature of the air compressor network, the air pressure in the air compressor network, the infrared image information of the pipeline, and the image information of the leak point.

[0058] A memory for storing the program of any of the above-mentioned air compressor control methods;

[0059] The processor and the program in the memory can be loaded and executed by the processor to implement any of the above-mentioned air compressor control methods.

[0060] Thirdly, this application provides a computer storage medium capable of storing corresponding programs, employing the following technical solution:

[0061] A computer-readable storage medium storing a computer program that can be loaded by a processor and executed by any of the above-described air compressor control methods.

[0062] Fourthly, this application provides a smart terminal, which adopts the following technical solution:

[0063] A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and executed any of the above-mentioned air compressor control methods.

[0064] In summary, this application includes at least one of the following beneficial technical effects:

[0065] 1. By setting up multiple air compressors, they can be rotated periodically, allowing them time to rest and reducing the likelihood of malfunctions. When an air compressor does fail, it can be replaced by a backup compressor, thus ensuring uninterrupted production.

[0066] 2. The water produced in the dryer can be cooled or heated using the ambient temperature during the day and night, and the cooled or heated water can be stored for other uses;

[0067] 3. By injecting heated water generated in the dryer into the pipeline, the air ejected from the leak point is given a certain temperature, making it easier for the infrared camera to identify and locate the leak. Attached Figure Description

[0075] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0076] This application discloses an air compressor control method. By setting up multiple air compressors and allowing them to be used in rotation, the air compressors are less prone to failure. Furthermore, the water produced in the dryer is discharged to different locations for different uses based on its temperature. When an abnormal pressure occurs in the air compressor pipeline network, it is identified and located using an infrared camera, and different methods of sealing are applied based on the pipe material and the location of the leak.

[0077] In this embodiment, the hole-reaming device, hole-reaming drill bit, robotic arm, welding device, cutting device, bending device, and hot-melting device are all mounted on the inspection robot.

[0078] Reference Figure 1 An air compressor control method includes the following steps:

[0079] Step S100: Determine the maximum gas volume required for production activities based on preset operating condition information.

[0080] The air pressure and volume required for producing a particular product are strictly regulated and are set as standard values. Operating condition information refers to the product being processed in the current production activity. Maximum air volume refers to the amount of air supplied by the air compressor required to process the current product. The maximum air volume can be obtained by determining the product currently being produced.

[0081] Step S101: Determine the number of air compressors to be started in the air compressor network based on the maximum air volume.

[0082] In this embodiment, in order to provide more air volume during production activities, multiple air compressors are set up and connected in parallel to form an air compressor network. When air is needed, a portion of the air compressors are selected to be turned on to provide a larger air volume.

[0083] Each air compressor has an upper limit on the amount of air it can provide. Therefore, the maximum air volume can be used to determine the number of air compressors that need to be turned on in the air compressor network to ensure normal air supply in production activities.

[0084] Step S102: Number the air compressors in the air compressor pipeline network to obtain the device number.

[0085] The device number refers to the number obtained by sequentially numbering each air compressor in the air compressor network. The purpose is to ensure that the selective operation of air compressors can be carried out in an orderly manner.

[0086] Step S103: Select the corresponding number of air compressors from the device numbers according to the number of units to start, and record the start-up time of the air compressors.

[0087] The selection method refers to the method of selecting the number of air compressors to be started from all air compressors in the air compressor network. This method is set by the technicians and will not be described in detail here. In this embodiment, the selection method mainly involves turning on the air compressors sequentially according to their device numbers.

[0088] Start-up time refers to the operating time of the air compressor after it is turned on. After starting up, the air compressor needs to be stopped and rested for a period of time to reduce the probability of air compressor failure.

[0089] Step S104: Determine the switching device based on the comparison between the power-on time and the preset baseline switching time.

[0090] The baseline switching time is a reference value set by technicians. It refers to the time required from the start of the air compressor to the point where the air compressor needs to be stopped for maintenance and switched to another idle air compressor for operation.

[0091] The air compressor can continue to operate as long as the start-up time is no longer than the reference switching time. However, if the start-up time exceeds the reference switching time, the air compressor is at risk of failure and therefore needs to be shut down for maintenance and switched to another idle air compressor.

[0092] Step S105: Based on the switching device, according to the preset rotation method, control the air compressor that has reached the reference switching time to shut down and control the air compressor that has not been started in the air compressor pipeline to start.

[0093] The rotation method refers to the method by which an air compressor is used in rotation with other idle air compressors when it needs to be shut down for maintenance. This method is manually set by technicians and will not be elaborated here. In this embodiment, the rotation method typically involves sequentially turning on the installed devices according to their numbers.

[0094] Reference Figure 2 In addition to air compressors, the air compressor piping network also includes dryers for drying and filtering the air produced by the air compressors. When the air compressor starts, the pre-installed dryers in the air compressor piping network will produce water. The water treatment method for the dryers includes the following steps:

[0095] Step S200: Obtain the water level in the dryer and the ambient temperature of the air compressor network.

[0096] The dryer has a chamber for storing the produced water, and the water level refers to the water level inside the chamber. The water level is measured by a water level sensor installed inside the chamber.

[0097] The ambient temperature value refers to the ambient temperature of the environment where the air compressor piping is located. The ambient temperature value can be obtained through temperature sensors installed on the air compressor piping.

[0098] Step S201: Determine whether to drain immediately upon overflow or drain under temperature control based on the comparison between the water level height and the preset drainage height.

[0099] The preset drainage height is a value set manually by technicians. When the water level in the dryer chamber reaches the drainage height, the water in the chamber will overflow, thus requiring drainage.

[0100] When the water level exceeds the drainage height, immediate overflow drainage will be implemented. Immediate overflow drainage means drainage will be carried out based on the water level.

[0101] When the water level is not greater than the drainage height, temperature-controlled drainage is carried out, which means drainage is carried out according to temperature changes.

[0102] Step S202: Based on the instant overflow drainage, control the water in the dryer to flow out to the preset water storage tank for storage.

[0103] During the overflow drainage process, the water in the chamber is drained into a water storage tank. The water storage tank, located on the side of the air compressor, is specifically designed to receive water produced by the dryer. In this embodiment, when the water level reaches the overflow drainage standard, one-third of the water in the chamber is drained, but two-thirds remain for use during temperature-controlled drainage.

[0104] Step S203: Based on temperature control, when the ambient temperature falls into the preset high temperature range, control the water in the dryer to flow out to the preset hot water pipe; when the ambient temperature falls into the preset low temperature range, control the water in the dryer to flow out to the preset cold water pipe.

[0105] In this embodiment, the water temperature inside the dryer chamber changes with temperature. During the coldest part of the night, the water temperature reaches its lowest point, forming cold water, while during the hottest part of the day, the water temperature reaches its highest point, forming hot water. Both cold and hot water are usable. Therefore, the distribution of water within the chamber is determined by monitoring the ambient temperature.

[0106] The high temperature range and the low temperature range are both reference values ​​set by technicians. The high temperature range refers to the highest temperature range during the day, and the low temperature range refers to the lowest temperature range at night. These will not be elaborated on here.

[0107] The dryer's chamber is connected to hot water pipes and cold water pipes, used for supplying hot and cold water respectively. When the ambient temperature enters the high-temperature range, the water in the chamber is hot, and this water is discharged into the hot water pipe. When the ambient temperature enters the low-temperature range, the water in the chamber is cold, and this water is discharged into the cold water pipe.

[0108] Reference Figure 3 After prolonged use, air compressor piping networks may experience leaks and other problems, leading to abnormal air pressure. The detection methods for abnormal air pressure in air compressor piping networks include the following steps:

[0109] Step S300: When the air compressor is running, obtain the pipeline air pressure of the air compressor network.

[0110] Pipeline air pressure refers to the air pressure value within the pipelines connected to the air compressor network and used for air delivery. The air pressure within the pipelines is at its maximum under normal conditions when the air compressor is running, therefore, this pressure is measured at this time. Pipeline air pressure is obtained using a barometer installed on the pipeline.

[0111] Step S301: Determine whether the pipeline air pressure is lower than the preset standard air pressure.

[0112] The standard air pressure is a reference value set manually by technicians and will not be elaborated upon here. During normal use, the air pressure in the air compressor pipeline will not be lower than the standard air pressure. Only during normal air use on the production line will a temporary low pressure occur. Once air use is complete, the pipeline pressure will return to the standard value. When the pipeline pressure is lower than the standard air pressure, there may be a pipeline leak.

[0113] Step S302: If and only if the pipeline air pressure is less than the standard air pressure, the pipeline air pressure shall be reacquired after a preset processing delay time.

[0114] If the pipeline air pressure is not less than the standard air pressure, it is considered normal and will not be taken into consideration.

[0115] When the pipeline gas pressure is lower than the standard gas pressure, it may be due to a temporary low pressure caused by normal gas usage on the production line. Therefore, a dual judgment method based on the processing delay time is introduced. The processing delay time is a reference value set manually by technicians, assuming that the production line can complete the gas usage within the processing delay time, which will not be elaborated here.

[0116] After the processing delay time, the pipeline air pressure is re-acquired and the pipeline air pressure status is assessed to avoid the pipeline air pressure being affected by production line operations.

[0117] Step S303: Determine the low-pressure type based on the comparison between the pipeline air pressure and the standard air pressure. The low-pressure type includes operating low pressure and leakage low pressure.

[0118] When the pipeline gas pressure is obtained again and is not less than the standard gas pressure, it indicates that the low pressure is being used, which is the low pressure caused by the normal gas usage on the production line.

[0119] If the pipeline air pressure is lower than the standard air pressure, and the influence of production line air consumption has been ruled out, it indicates that there may be a leak in the air compressor network pipeline.

[0120] Step S304: Based on the low leakage pressure, determine the location of the leak point according to the pipeline leak point location method, control the main air valve pre-installed in the air compressor pipeline to close, and seal the leak point location using the leak point sealing method.

[0121] When a pipeline leak occurs, the leak point must first be located, then the main air valve must be closed, and finally the leak must be sealed. The method for locating the leak point is used to pinpoint its location and will not be elaborated upon here, but will be described in detail in a later section. The method for sealing the leak point is used to plug the leak and will not be elaborated upon here, but will be described in detail in a later section.

[0122] Reference Figure 4 The method for locating pipeline leaks includes the following steps:

[0123] Step S400: Determine the number of infrared cameras to be installed based on the preset recognition range and preset pipe length, and number the infrared cameras to obtain infrared numbers.

[0124] The recognition range refers to the area that the infrared camera can capture. Pipeline length refers to the length of the air compressor's piping network. For long piping distances, multiple infrared cameras are needed to monitor every part of the pipeline.

[0125] The number of infrared cameras installed is determined by their detection range and the length of the pipeline, with the principle of uniform and comprehensive coverage. The infrared camera number refers to the unique identifier of each camera. When an infrared camera detects a pipeline leak, it can pinpoint which camera detected the anomaly and pinpoint the location; therefore, each infrared camera is assigned a number.

[0126] Step S401: Control the preset atomizing device connected to the hot water pipe to turn on and fill the hot water in the hot water pipe into the air compressor pipeline in the form of atomization.

[0127] In this embodiment, the hot water generated in the dryer during the day is atomized by an atomizing device and then injected into the pipeline, so that the air in the pipeline has a certain temperature. When the air comes out from the leak point, it is easily captured by an infrared camera.

[0128] Step S402: Control the infrared camera to acquire infrared image information of the pipeline.

[0129] Infrared image information refers to images of pipelines captured by infrared cameras. When a leak occurs, the temperature of the ejected air will be reflected in the infrared image information.

[0130] Step S403: Match the infrared image information with the preset infrared database to determine the infrared number corresponding to the abnormal camera.

[0131] The infrared database is a database set up by technicians, which includes information on the colors captured by infrared cameras at various temperatures, and will not be elaborated upon here. When infrared image information is matched with the infrared database and a red block image appears, it indicates that the temperature in that area is higher than that in other locations, and this area may be a leak point. In this case, the infrared camera showing the abnormal red block data is marked as an abnormal camera, and its infrared number is recorded.

[0132] Step S404: Match the pipes identified by the corresponding infrared camera according to the infrared number, and determine the location of the leak point by matching the infrared image information and the infrared database.

[0133] Once the infrared identifier is determined, the specific infrared camera and the location of the pipeline identified by that camera can be identified. Finally, the exact location of the leak in the pipeline can be determined from the infrared database using the infrared image information.

[0134] Reference Figure 5 The method for sealing leak points includes the following steps:

[0135] Step S500: Obtain image information of the leak point location.

[0136] The leak point image information is an image of the location of the leak point in the pipeline, which is obtained by a camera that monitors the pipeline in real time.

[0137] Step S501: Determine the area of ​​the leak point and the material information of the pipeline based on the image information of the leak point.

[0138] The leak point area refers to the size of the cavity at the location of the leak in the pipeline. Pipe material information refers to the material of the pipeline, mainly distinguishing between metal and plastic.

[0139] The area of ​​the leak point can be obtained directly through image analysis of the leak point image information, which is existing technology and will not be elaborated here.

[0140] By matching the leak point image information with a preset material database, it is possible to determine whether the pipeline is made of metal or plastic.

[0141] Step S502: Determine the sealing type based on the comparison between the pipe material information and the preset reference material. The sealing types include metal sealing and plastic sealing.

[0142] The reference material was set by the technicians and will not be elaborated here. In this embodiment, the reference material is metal. When the pipe material information matches the reference material, i.e., the pipe is made of metal, the leak point is sealed according to the metal sealing method. If the pipe material information does not match the reference material, i.e., the pipe is made of plastic, the leak point is sealed according to the plastic sealing method.

[0143] Step S503: Based on the metal plugging, determine whether the area of ​​the leak point is smaller than the preset benchmark plugging area.

[0144] If the pipeline is made of metal, the sealing method will also differ depending on the area of ​​the leak point. Therefore, it is necessary to first determine the area of ​​the leak point.

[0145] The baseline sealing area is a reference value set by technicians to divide the area of ​​the leak point. Different metal sealing methods are used for different leak point areas.

[0146] Step S504: If and only if the area of ​​the leak point is smaller than the reference sealing area, match the corresponding reaming drill bit according to the area of ​​the leak point, and control the reaming drill bit to ream the leak point location, re-acquire the leak point image information of the leak point location and determine the reaming point outline.

[0147] When the area of ​​the leak point is smaller than the reference sealing area, it indicates that the leak point area is small. For small leak points, this embodiment adopts a method of first enlarging the hole, then inserting a metal cylindrical sealing post to seal it, and finally welding for reinforcement.

[0148] Enlarging is used to enlarge the leak point to a size suitable for inserting a cylindrical sealing post. A matching reaming drill bit is used based on the area of ​​the leak point, and then the hole is enlarged using a pre-set reaming device and the reaming drill bit. The reaming point profile refers to the outline of the leak point location after reaming.

[0149] Step S505: Match the corresponding sealing column according to the leak point contour, control the sealing column to extend into the leak point position, and control the preset welding device to weld and reinforce along the leak point contour.

[0150] After determining the outline of the reaming point, a sealing post of the corresponding diameter can be determined based on the outline. The sealing post is a metal cylinder made of the same material as the pipeline. After the robotic arm controls the insertion of the sealing post into the location of the leak point after reaming, it can precisely seal the leak point. Then, a welding device is used to weld around the leak point outline for reinforcement.

[0151] Reference Figure 6 When the area of ​​the leak point is not less than the reference sealing area, the sealing method at the leak point location includes the following steps:

[0152] Since the leak point area is large, the methods in steps S504 and S505 are likely to block the pipeline and prevent air from passing through. In this embodiment, a metal sealing plate that can be cut from the metal plate according to the outline shape of the leak point is exactly matched with the leak point. Then, the metal sealing plate is pressed tightly by clamping the pipeline with metal strips, so that it is not easy to leak air.

[0153] Step S600: Determine the outline information of the leak point based on the image information of the leak point.

[0154] Leakage point contour information refers to the cavity contour at the location of the leak point. Leakage point contour information can be obtained directly from the image information of the leak point through image analysis, which is existing technology and will not be elaborated here.

[0155] Step S601: Generate a cutting path based on the leak point contour information.

[0156] The cutting path is the path along which the cutting device moves to cut out the metal sealing block on the metal plate. The cutting path is obtained by fitting the leakage point contour information.

[0157] Step S602: Control the preset cutting device according to the cutting path to cut a sealing plate that matches the outline information of the leakage point on the preset metal plate.

[0158] Once the cutting path is determined, a sealing plate matching the leak point contour information can be cut from the metal plate using the cutting device. Both the metal plate and the cutting device are pre-positioned on the inspection robot.

[0159] Step S603: Control the welding device to weld the sealing plate to the preset metal strip, and control the sealing plate to be embedded in it according to the location of the leak point.

[0160] After obtaining the metal sealing plate, the sealing plate and the metal strip pre-placed on the inspection robot are welded together using a welding device. Then, the sealing plate is embedded into the location of the leak point according to the location of the leak point. At this time, the metal strip has not yet tightened the pipeline.

[0161] Step S604: Control the preset bending device according to the preset pipe cross-sectional profile to bend the metal strip to fit the outer wall of the pipe and press the sealing plate tightly at the leak point.

[0162] Once the sealing plate is embedded at the leak point, the bending device can bend the metal strip according to the pipe cross-sectional profile to tighten the pipe, thereby pressing the sealing plate firmly at the leak point.

[0163] Reference Figure 7 The method of plastic sealing includes the following steps:

[0164] Since plastic is easily melted by heat, in this embodiment, a plastic sheet with a similar outline to the leak point is melted and then melted together with the leak point to seal the leak.

[0165] Step S700: Based on plastic sealing, determine the outline information of the leak point according to the image information of the leak point.

[0166] The same as step S600, so it will not be repeated here.

[0167] Step S701: Determine the plastic contour information of the preset sealing plastic sheet based on the leakage point contour information.

[0168] Plastic profile information refers to the profile of the sealing plastic sheet used to plug leaks, obtained through heat melting. The plastic profile information corresponds to the leak point profile information; the plastic profile information can be fitted based on the leak point profile information.

[0169] Step S702: Control the preset hot melt device to hot melt the preset plastic sheet according to the plastic contour information to obtain the sealing plastic sheet after edge hot melt.

[0170] The inspection robot is equipped with a plastic plate. Once the plastic outline information is determined, the hot-melt device directly melts the plastic plate using the plastic outline information as the moving path. At this time, a sealing plastic piece of the same size as the leak point and with its edges in a hot-melt state can be removed from the plastic plate.

[0171] Step S703: Control the insertion of the sealing plastic sheet into the leak point to heat-melt the edge of the sealing plastic sheet to the edge of the leak point.

[0172] While the edge of the sealing plastic sheet is still in a molten state, a robotic arm embeds the plastic sheet into the leak location. At this point, the edge of the sealing plastic sheet can be molten together with the edge of the leak location in the pipeline, thereby achieving the purpose of sealing.

[0173] Step S704: Control the cold water pipe to spray water for cooling based on the leak point contour information.

[0174] After the sealing plastic sheet is connected to the pipeline, the leak point is sprayed with cold water generated at night by the dryer to achieve the purpose of cooling.
