Description

Technical Field

[0001] The present invention relates to the field of air compressors, and in particular to an air compressor control method, system, storage medium and terminal. Background Art

[0002] An air compressor is a mechanical device used to compress gas. Its working principle is mainly to drive the compressor rotor to rotate through the motor, suck in air and gradually compress it, and finally release the compressed air. In most water flow line factories, most pneumatic tools such as pneumatic wrenches and pneumatic drills use compressed air as a power source, so air compressors are widely used in various fields.

[0003] At present, many processing enterprises use air compressor pipe network devices composed of multiple air compressors to meet the air demand of large processing equipment. When controlling the air compressor pipe network device, enterprises usually start all air compressors to work, and when adjusting the air size, they synchronously control all air pressures to adjust the power. The air compressor may fail after working for a long time. When controlling the air compressor by the above method, if one of the air compressors fails, the air pressure output by the air compressor pipe network device as a whole will not reach the expected setting, thereby affecting the actual processing and production, which needs to be improved. Summary of the invention

[0004] In order to solve the problem that the air pressure output by the air compressor pipe network device as a whole is affected by the failure of a single air compressor, the present 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 in production activities based on preset working condition information;

[0008] Determine the number of air compressors to be started in the air compressor network based on the maximum gas volume;

[0009] Numbering the air compressors in the air compressor network to obtain device numbers;

[0010] According to the number of units to be started, a corresponding number of air compressors are selected from the device numbers using a preset selection method for startup, and the startup time of the air compressors is recorded;

[0011] Determining the switching device based on a comparison between the power-on time and a preset reference switching time;

[0012] Based on the switching device, the air compressor that has reached the reference switching time is controlled to be turned off according to the preset rotation method, and the air compressor that has not been started in the air compressor pipeline network is controlled to be turned on.

[0013] By adopting the above technical solution, multiple air compressors are set up to form an air compressor network, and a certain number of air compressors are selected from the air compressor network according to the maximum gas volume to start operation, and a part of the air compressors are reserved as spares. After the air compressors have been running for a certain period of time, the running air compressors are regularly replaced with spare air compressors, so that the air compressors can have rest time and are less likely to fail. When an air compressor fails, it can also be replaced with a spare air compressor, so as not to affect the actual processing and production.

[0014] Optionally, when the air compressor is started, a dryer preset in the air compressor pipe network will generate water. The method for processing the water in the dryer includes:

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

[0016] Determine overflow instant drainage or temperature-controlled drainage based on the comparison between the water level value and the preset drainage height;

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

[0018] Based on temperature-controlled drainage, when the ambient temperature value falls into 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 value falls into 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 generated in the dryer can be reasonably utilized. The influence of the ambient temperature during the day and at night on the temperature of the water is utilized. The ambient temperature during the day can heat the water, while the ambient temperature at night can cool the water. In this way, the hot water generated during the day and the cold water generated at night can be stored and can be used for other purposes.

[0020] Optionally, also include:

[0021] When the air compressor is running, obtain the pipeline air pressure of the air compressor network;

[0022] Determine whether the pipeline air pressure is less than the preset standard air pressure;

[0023] If and only if the pipeline air pressure is lower than the standard air pressure, the pipeline air pressure is re-obtained after the preset processing delay time;

[0024] The low pressure type is determined based on the comparison between the pipeline gas pressure and the standard gas pressure. The low pressure types include low pressure in use and low pressure in leakage.

[0025] Based on the leakage low pressure, the leakage point location is determined according to the pipeline leakage point positioning method, the main air valve preset in the air compressor pipeline is controlled to be closed, and the leakage point location is sealed using the leakage point sealing method.

[0026] Optionally, pipeline leak location methods include:

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

[0028] Control the preset atomizing device connected to the hot water pipe to start and fill the hot water in the hot water pipe into the pipeline of the air compressor network in the form of mist;

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

[0030] Matching the infrared image information with a preset infrared database to determine the infrared number corresponding to the abnormal camera;

[0031] The infrared number is matched with the corresponding pipeline identified by the infrared camera, and the location of the leakage point is determined 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 leakage point has a certain amount of heat, which can be detected by the infrared camera. The above method is easy to locate the leakage point and is relatively convenient.

[0033] Optional leak point plugging methods include:

[0034] Obtaining leakage point image information of the leakage point location;

[0035] Determine the leakage point area and pipeline material information based on the leakage point image information;

[0036] Determine the plugging type based on the comparison between the pipeline material information and the preset reference material, and the plugging types include metal plugging and plastic plugging;

[0037] Based on metal plugging, determine whether the leakage point area is smaller than the preset reference plugging area;

[0038] If and only if the leakage point area is smaller than the reference plugging area, match the corresponding reaming drill bit according to the leakage point area, control the reaming drill bit to reaming the leakage point position, reacquire the leakage point image information of the leakage point position and determine the reaming point contour;

[0039] According to the contour of the leakage point, a corresponding plugging column is matched, the plugging column is controlled to extend into the position of the leakage point and the preset welding device is controlled to perform welding reinforcement along the contour of the leakage point.

[0040] By adopting the above technical solution, when the air compressor pipeline is made of metal and the area of ​​the leakage point is small, the leakage point is expanded to form a hole for the plugging column to be inserted, and then the plugging column and the pipeline are welded by a welding device. The above method can better plug the leakage point, and the plugging column is not easily withdrawn from the leakage point under the action of air pressure. At the same time, since the diameter of the plugging column is small, it is not easy to cause blockage to the pipeline after being inserted into the pipeline.

[0041] Optionally, when the leakage point area is not less than the reference plugging area, the plugging method for the leakage point location includes:

[0042] Determine the contour information of the leakage point according to the image information of the leakage point;

[0043] Generate cutting path according to the leakage point contour information;

[0044] Controlling a preset cutting device according to a cutting path to cut a plugging plate matching the contour information of the leakage point on a preset metal plate;

[0045] Control the welding device to weld the plugging plate to the preset metal strip, and control the plugging plate to be embedded therein according to the position of the leakage point;

[0046] According to the preset pipeline cross-sectional profile, the preset bending device is controlled to bend the metal strip to fit the outer wall of the pipeline and press the sealing plate to the leakage point.

[0047] By adopting the above technical solution, when the leakage point area is large, a sealing plate consistent with the contour of the leakage point is cut out by a cutting device, and after the sealing plate is embedded in the leakage point position, the metal strip is bent into the form of a pipe to press the sealing plate against the leakage point. The above method can be applied to situations where the leakage point area is large, and the sealing plate does not need to extend into the pipe, so it is not easy to cause blockage to the pipe.

[0048] Optional plastic plugging methods include:

[0049] Based on plastic plugging, the contour information of the leakage point is determined according to the image information of the leakage point;

[0050] Determining plastic contour information of a preset plugging plastic sheet according to the contour information of the leakage point;

[0051] According to the plastic profile information, a preset hot-melt device is controlled to hot-melt the preset plastic plate to obtain a sealing plastic sheet after the edge is hot-melted;

[0052] Control the sealing plastic sheet to be embedded in the leak point so as to connect the edge of the sealing plastic sheet with the edge of the leak point by hot melting;

[0053] According to the leakage point contour information, the cold water pipe is controlled to spray water for cooling.

[0054] By adopting the above technical solution, if the pipe is made of plastic, a sealing plastic sheet with the same contour as the leakage point can be hot-melted at the leakage point, thereby repairing the pipe, which is more convenient.

[0055] In a second aspect, the present application provides an air compressor control system, which adopts the following technical solution:

[0056] An air compressor control system, comprising:

[0057] An acquisition module is used to acquire the water level value in the dryer, the ambient temperature value of the air compressor pipe network, the pipe pressure of the air compressor pipe network, the infrared image information of the pipe, and the image information of the leakage point;

[0058] A memory, used to store a program of any one of the above-mentioned air compressor control methods;

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

[0060] In a third aspect, the present application provides a computer storage medium capable of storing a corresponding program, using the following technical solution:

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

[0062] In a fourth aspect, the present application provides an intelligent terminal, which adopts the following technical solution:

[0063] An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and execute any one of the above-mentioned air compressor control methods.

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

[0065] 1. By setting up multiple air compressors, the air compressors can be rotated regularly, so that the air compressors can have time to rest and are less likely to fail. When an air compressor fails, it can also be replaced with a spare air compressor, so as not to affect the actual processing and production;

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

[0067] 3. By injecting heated water produced by the dryer into the pipeline, the air ejected from the leak point has a certain temperature, making it easier for the infrared camera to identify and locate it. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0076] The embodiment of the present application discloses an air compressor control method. By setting up multiple air compressors and being able to use them in rotation, the air compressors are less likely to malfunction. And the water generated in the dryer is discharged to different locations for different uses according to different temperatures. When the pressure in the air compressor pipe network is abnormal, it is identified and located by an infrared camera, and different methods of blocking are performed according to the pipe material and the location of the leak point of the air compressor pipe network.

[0077] The reaming device, reaming drill, manipulator, welding device, cutting device, bending device, hot-melt device, etc. that appear in this embodiment are all arranged on the inspection robot.

[0078] Reference Figure 1 , an air compressor control method comprises the following steps:

[0079] Step S100: determining the maximum gas volume required for production activities according to preset working condition information.

[0080] The parameters such as air pressure and air volume required to produce a certain product are strictly regulated and are standard values. Working condition information refers to the information of the product being processed in the current production activity. The maximum air volume refers to the amount of air provided 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: determining the number of air compressors to be started that are preset in the air compressor network according to the maximum gas volume.

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

[0083] There is an upper limit to the amount of air that each air compressor can provide. Therefore, the maximum gas 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 gas use in production activities.

[0084] Step S102: numbering the air compressors in the air compressor network to obtain device numbers.

[0085] The device number refers to the number obtained by numbering each air compressor in the air compressor network in sequence. The purpose is to enable the selective opening of the air compressor to proceed in an orderly manner in a certain order.

[0086] Step S103: Select a corresponding number of air compressors from the device numbers according to the startup quantity using a preset selection method to start up, and record the startup time of the air compressors.

[0087] The selection method refers to a method for selecting the air compressors with the number of air compressors to be turned on from all the 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 is mainly to turn on the air compressors in sequence according to the device numbers.

[0088] The startup time refers to the time the air compressor runs after it is turned on. After starting up, the air compressor needs to be shut down for a period of time to reduce the probability of failure.

[0089] Step S104: Determine the switching device according to the comparison between the power-on time and the preset reference switching time.

[0090] The benchmark switching time is a reference value set by the technician, which refers to the time required from the start of the air compressor to the time when the air compressor needs to be shut down for maintenance and switched to another idle air compressor to work.

[0091] When the startup time is not greater than the reference switching time, the air compressor can continue to work. When the startup time is greater than the reference switching time, the air compressor is at risk of failure, so it is necessary to shut down the air compressor for maintenance and switch to other idle air compressors to continue working.

[0092] Step S105: Based on the switching device, according to a preset rotation method, the air compressor that has reached the reference switching time is controlled to be turned off and the air compressor that has not been started in the air compressor pipeline network is controlled to be turned on.

[0093] The rotation method refers to the method of rotating the air compressor with other idle air compressors when the air compressor needs to be shut down for maintenance. The method is set by the technicians and will not be described in detail. In this embodiment, the rotation method is usually to rotate and open the installation device numbers in sequence.

[0094] Reference Figure 2 In addition to the air compressor, the air compressor network also has a dryer for drying and filtering the air generated by the air compressor. When the air compressor is started, the dryer preset in the air compressor network will produce water. The method for treating the water in the dryer includes the following steps:

[0095] Step S200: obtaining the water level value of the dryer and the ambient temperature value of the air compressor pipe network.

[0096] The dryer has a chamber for storing the generated water, and the water level value refers to the water level value of the water in the chamber. The water level value can be measured by a water level sensor arranged in the chamber.

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

[0098] Step S201: Determine overflow instant drainage or temperature-controlled drainage based on a comparison between the water level value and a preset drainage height.

[0099] The preset drainage height is a value set manually by the technicians. When the water level in the chamber of the dryer reaches the drainage height, the water in the chamber will overflow, so it is necessary to drain the water.

[0100] When the water level value is greater than the drainage height, the overflow is immediately drained. Overflow immediate drainage means draining according to the water level value.

[0101] When the water level height value is not greater than the drainage height, temperature-controlled drainage is performed. Temperature-controlled drainage means drainage is performed according to temperature changes.

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

[0103] When the overflow is drained, the water in the chamber is drained into the water storage tank. The water storage tank is set on the side of the air compressor and is specially used to receive the water generated by the dryer. In this embodiment, when the water level reaches the overflow instant drain standard, one-third of the water in the chamber is drained, but two-thirds of the water is still left for temperature control drainage.

[0104] Step S203: Control the drainage based on the temperature. 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 in the chamber of the dryer changes with the temperature. When it is the coldest time at night, the water temperature can reach the lowest point to form cold water, and when it is the hottest time during the day, the water temperature can reach the highest point to form hot water. Both cold water and hot water have utilization value. Therefore, the distribution of water in the chamber is determined by detecting the ambient temperature value.

[0106] The high temperature range and the low temperature range are 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. They will not be elaborated here.

[0107] The dryer chamber is connected to a hot water pipe and a cold water pipe, which are used to supply hot water and cold water respectively. When the ambient temperature value enters the high temperature range, the water in the chamber is hot water, and the water is discharged to the hot water pipe. When the ambient temperature value enters the low temperature range, the water in the chamber is cold water, and the water is discharged to the cold water pipe.

[0108] Reference Figure 3 After long-term use, the air compressor pipe network may have problems such as pipeline leakage, resulting in abnormal air pressure. The method for detecting abnormal air pressure in the air compressor pipe network includes the following steps:

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

[0110] Pipeline air pressure refers to the air pressure value in the pipeline connected to the air compressor network and used for air transportation. When the air compressor is running, the air pressure in the pipeline is normally the highest, so the air pressure in the pipeline is obtained at this time. The pipeline air pressure is obtained through a barometer installed on the pipeline.

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

[0112] The standard air pressure is a reference value set by technicians, which will not be elaborated here. When the air compressor network is in normal use, the air pressure in the pipeline will not be lower than the standard air pressure. Only when the air is used normally on the production line will a temporary low pressure be generated. When the air is used, the pipeline air pressure will return to the standard value. When the pipeline air 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, re-obtain the pipeline air pressure after a preset processing delay time.

[0114] It is normal if the pipeline air pressure is not less than the standard air pressure and is not taken into consideration.

[0115] When the pipeline pressure is lower than the standard pressure, there may be a temporary low pressure due to normal gas use on the production line, so a dual judgment method for the processing delay time is introduced. The processing delay time is a reference value set by the technicians. It is assumed that the production line can complete the gas use within the processing delay time, which will not be elaborated here.

[0116] After the processing delay time, the pipeline air pressure is obtained again and the pipeline air pressure condition is judged to avoid the pipeline air pressure being affected by the production line production.

[0117] Step S303: Determine the low pressure type according to the comparison between the pipeline air pressure and the standard air pressure. The low pressure type includes use low pressure and leakage low pressure.

[0118] When the pipeline gas pressure obtained again is not less than the standard gas pressure, it means that low pressure is used, that is, the low pressure caused by normal gas use on the production line.

[0119] When the pipeline air pressure is lower than the standard air pressure, excluding the influence of the production line gas consumption, it means that there may be a leak in the pipeline of the air compressor network management.

[0120] Step S304: Based on the leakage low pressure, the leakage point position is determined according to the pipeline leakage point positioning method, the main air valve preset in the air compressor pipeline is controlled to be closed, and the leakage point position is blocked by the leakage point blocking method.

[0121] When a leak occurs in the pipeline, it is necessary to locate the leak first, then close the main air valve, and finally seal it. The pipeline leak point location method is used to locate the leak point, which will not be described in detail here, and will be described in detail in the subsequent plan. The leak point sealing method is used to seal the leak point, which will not be described in detail here, and will be described in detail in the subsequent plan.

[0122] Reference Figure 4 , the pipeline leakage point positioning method includes the following steps:

[0123] Step S400: determining the number of infrared cameras to be installed according to a preset recognition range of the infrared cameras and a preset pipe length, and numbering the infrared cameras to obtain infrared numbers.

[0124] The recognition range refers to the range of the image that the infrared camera can capture. The pipeline length refers to the length of the pipeline of the air compressor network. If the pipeline distance is long, in order to enable the infrared camera to monitor every part of the pipeline, multiple infrared cameras need to be set up.

[0125] The number of infrared cameras installed is determined by the infrared camera's recognition range and the length of the pipeline, with uniform and comprehensive coverage as the principle. The infrared number refers to the number of the infrared camera. When the infrared camera monitors a pipeline leak, it can be clearly identified which camera monitored the abnormal situation and can be located accordingly, so each infrared camera is numbered.

[0126] Step S401: Control a preset atomizing device connected to a hot water pipe to start and fill the hot water in the hot water pipe into the pipeline of the air compressor network in the form of mist.

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

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

[0129] Infrared image information refers to the image of the pipeline captured by an infrared camera. When a leak occurs, the air ejected has temperature, so the temperature of the air can be reflected in the infrared image information.

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

[0131] The infrared database is a database set by technicians, which includes information on the colors captured by infrared cameras at various temperatures. I will not go into details here. When a red block image appears when matching the infrared image information with the infrared database, it means that the temperature in this area is higher than that in other locations. This area may be the location of a leak. At this time, the infrared camera with abnormal red block data is marked as an abnormal camera, and its infrared number is recorded.

[0132] Step S404: Match the infrared number with the corresponding pipeline identified by the infrared camera, and determine the location of the leakage point by matching the infrared image information with the infrared database.

[0133] When the infrared number is determined, the specific infrared camera and the pipeline position identified by the infrared camera can be determined according to the infrared number. Finally, the specific leakage point position of the pipeline position can be determined from the infrared database through the infrared image information.

[0134] Reference Figure 5 , the leakage point blocking method includes the following steps:

[0135] Step S500: Acquire leakage point image information of the leakage point location.

[0136] The leakage point image information is an image of the leakage point of the pipeline, and the leakage point image information is obtained through a camera that monitors the pipeline in real time.

[0137] Step S501: determining the leakage point area and pipeline material information according to the leakage point image information.

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

[0139] The leakage point area can be directly obtained by performing image analysis on the leakage point image information, which is a prior art and will not be described in detail here.

[0140] By matching the image information of the leak point with the preset material database, it can be determined whether the pipeline is metal or plastic.

[0141] Step S502: Determine the plugging type based on the comparison between the pipeline material information and the preset reference material, and the plugging types include metal plugging and plastic plugging.

[0142] The reference material is set by the technicians and will not be described in detail here. In this embodiment, the reference material is metal. When the pipeline material information is consistent with the reference material, that is, the pipeline is made of metal, the leak point is blocked according to the metal blocking method. If the pipeline material information is inconsistent with the reference material, the pipeline is made of plastic, and the leak point is blocked according to the plastic blocking method.

[0143] Step S503: Based on the metal plugging, determine whether the leakage point area is smaller than a preset reference plugging area.

[0144] If the pipeline is made of metal, the sealing method will be different if the leakage point area is different, so it is necessary to judge the leakage point area first.

[0145] The benchmark plugging area is a reference value set by technical personnel and is used to divide the leakage point area. Different metal plugging methods are used for different leakage point areas.

[0146] Step S504: When and only when the leakage point area is smaller than the reference plugging area, match the corresponding reaming drill bit according to the leakage point area, control the reaming drill bit to reame the leakage point position, reacquire the leakage point image information of the leakage point position and determine the reaming point contour.

[0147] When the area of ​​the leakage point is smaller than the reference plugging area, it means that the area of ​​the leakage point is small. For small leakage points, this embodiment adopts a method of first expanding the circular hole, then inserting a metal cylindrical plugging column to plug it, and finally welding and reinforcing it.

[0148] Hole enlargement is to enlarge the leak point to a size suitable for the insertion of a cylindrical plugging column. The corresponding type of hole enlargement drill bit can be matched according to the area of ​​the leak point, and then the hole enlargement is performed with the hole enlargement drill bit through the preset hole enlargement device. The hole enlargement point contour refers to the contour of the leak point after the hole enlargement is completed.

[0149] Step S505: Match the corresponding plugging column according to the contour of the leakage point, control the plugging column to extend into the position of the leakage point and control the preset welding device to perform welding reinforcement along the contour of the leakage point.

[0150] After determining the contour of the expansion point, the corresponding diameter of the plugging column can be determined according to the contour of the expansion point. The plugging column is a metal cylinder made of the same material as the pipeline. After the manipulator controls the plugging column to insert into the leaking point after the expansion, it can just plug the leaking point, and then use the welding device to weld a circle along the contour of the leaking point for reinforcement.

[0151] Reference Figure 6 When the leakage point area is not less than the reference plugging area, the plugging method of the leakage point location includes the following steps:

[0152] Since the area of ​​the leakage point is large, the method of step S504 and step S505 is likely to block the pipeline and air cannot pass through. In this embodiment, a metal sealing plate that can just match the position of the leakage point is cut from the metal plate according to the contour shape of the leakage point, and then the metal sealing plate is tightened by tightening the pipeline with a metal strip to prevent air leakage.

[0153] Step S600: determining the leakage point contour information according to the leakage point image information.

[0154] The leakage point contour information refers to the hole contour of the leakage point position. The leakage point contour information can be directly obtained from the leakage point image information by image analysis. This is a prior art and will not be described in detail here.

[0155] Step S601: Generate a cutting path according to the leakage point contour information.

[0156] The cutting path is the path that the cutting device moves when cutting the metal plugging block on the metal plate. The cutting path is obtained by fitting the contour information of the leakage point.

[0157] Step S602: controlling a preset cutting device according to a cutting path to cut a plugging plate matching the contour information of the leakage point on a preset metal plate.

[0158] After the cutting path is determined, a plugging plate matching the contour information of the leakage point can be cut from the metal plate by the cutting device. The metal plate and the cutting device are both pre-positioned on the inspection robot.

[0159] Step S603: Control the welding device to weld the plugging plate to the preset metal strip, and control the plugging plate to be embedded therein according to the position of the leakage point.

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

[0161] Step S604: According to the preset pipeline cross-sectional profile, the preset bending device is controlled to bend the metal strip to fit the outer wall of the pipeline and to press the sealing plate to the leakage point.

[0162] When the plugging plate is embedded in the leakage point, the bending device can bend the metal strip according to the cross-sectional profile of the pipeline to tighten the pipeline, thereby pressing the plugging plate to the leakage point.

[0163] Reference Figure 7 , the plastic plugging method comprises the following steps:

[0164] Since plastic is easy to melt by heat, in this embodiment, a plastic sheet with a contour close to the leak point is melted out by heat and melted together with the leak point to achieve the purpose of blocking the leak point.

[0165] Step S700: Based on plastic plugging, determine the contour information of the leakage point according to the image information of the leakage point.

[0166] This is the same as step S600 and will not be described in detail here.

[0167] Step S701: determining the plastic contour information of the preset blocking plastic sheet according to the leakage point contour information.

[0168] The plastic contour information refers to the contour of the plugging plastic sheet obtained by hot melting and used to plug the leak point. The plastic contour information corresponds to the leak point contour information, and the plastic contour information can be fitted according to the leak point contour information.

[0169] Step S702: controlling a preset hot-melt device to hot-melt a preset plastic plate according to the plastic contour information to obtain a sealing plastic sheet after the edges are hot-melted.

[0170] A plastic plate is arranged on the inspection robot. After the plastic contour information is determined, the hot melt device directly performs hot melting on the plastic plate using the plastic contour information as the moving path. At this time, a sealing plastic sheet with the same size as the leakage point and the edge in a hot melt state can be removed from the plastic plate.

[0171] Step S703: Control the sealing plastic sheet to be embedded into the leakage point to thermally melt the edge of the sealing plastic sheet and the edge of the leakage point.

[0172] When the edge of the sealing plastic sheet is still in a hot-melt state, the plastic sheet is embedded into the leakage point by a robot. At this time, the edge of the sealing plastic sheet can be hot-melted together with the edge of the leakage point of the pipeline, thereby achieving the purpose of sealing.

[0173] Step S704: Control the cold water pipe to spray water for cooling according to the leakage point contour information.

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