Description

Technical Field

[0001] The invention relates to the field of sweeper control, and in particular to an artificial intelligence-based sweeper heating scraper control system and method thereof. Background Art

[0002] During the operation of the belt conveyor, it is inevitable that materials will stick to the surface of the conveyor belt, and they cannot be completely unloaded after passing through the unloading device. When the working surface of the conveyor belt with materials on the surface passes through the lower roller and the redirecting roller, the materials on the belt surface will stick to the lower roller and the redirecting roller, increasing their diameter, aggravating the wear of the roller and the redirecting roller on the belt, and causing the belt to deviate. The continuously falling materials will pollute the site environment. Therefore, cleaning the materials adhering to the belt surface is of great significance to prolonging the life of the belt and ensuring the normal operation of the belt.

[0003] The cleaner is a cleaning device for the adhesion and bulky materials of the belt conveyor. Its main function is to remove the residual materials adhering to the conveyor belt to prevent these materials from re-entering the conveying system and causing additional wear or failure. The working condition of the belt conveyor cleaner is crucial to ensure the efficient operation of the conveying system and extend the life of the equipment.

[0004] However, the existing belt conveyor cleaner control system still has some limitations and shortcomings in practical applications.

[0005] For example, the existing Chinese patent with publication number CN110921245A discloses a sweeper and a method for cleaning materials on the surface of a belt conveyor, including a scraper, a transmission tube, a transmission shaft I, and a transmission shaft II. The blade body of the scraper is fixedly connected to the transmission tube, and the transmission shaft I and the transmission shaft II are respectively connected to one end of the transmission tube, so that the two ends of the transmission tube are each connected to a transmission shaft, and the transmission shaft I is connected to the output shaft of the reduction box of the asynchronous motor. The frequency converter is connected to the asynchronous motor to drive the asynchronous motor. The effect is that under the rotation control of the asynchronous motor, the scraper position can be adjusted in the corresponding clockwise and counterclockwise rotation, so that the front edge of the scraper can be adjusted by rotation to adjust the degree of pressure against the belt surface of the belt conveyor.

[0006] The above patent solves the problem that the cleaning effect is deteriorated or even fails due to the fixing method of the existing scraper clamping method, but there are the following shortcomings: (1) The cleaner does not have heating and temperature control functions: under extremely cold conditions, the belt conveyor cleaner cannot clean thoroughly and cannot achieve the expected cleaning effect due to the cold adhesion, freezing of materials on the conveyor belt or the ice layer formed by rain and snow. This is particularly obvious when the belt conveyor is stopped or the working conditions are extremely cold.

[0007] (2) Lack of monitoring and adjustment of the installation angle of the sweeper scraper: The sweeper scraper needs to be installed at a specific angle so that it can effectively scrape the material off the belt. If the installation angle is too large, it may increase wear, while if the installation angle is too small, it may not be able to clean effectively.

[0008] (3) Lack of monitoring and analysis of scraper wear: When the scraper is worn, its cleaning efficiency will be reduced and the risk of material residue will increase. Therefore, it is necessary to regularly check the wear condition of the scraper and replace the severely worn scraper parts in time. Summary of the invention

[0009] In view of the above problems, the present invention proposes a sweeper heating scraper control system and method based on artificial intelligence to realize the function of controlling the sweeper.

If correction is required, obtain the correction information of the sweeper scraper installation angle, further analyze the sweeper scraper installation distance adjustment information, and provide feedback. If correction is not required, maintain the original installation angle of the sweeper scraper.

[0013] Cleaner heating start demand judgment module: used to obtain thermal imaging images of the belt surface of the belt conveyor to determine whether the belt surface of the belt conveyor is frozen. If it is frozen, the heating unit of the cleaner needs to be started. If it is not frozen, the heating unit of the cleaner does not need to be started.

[0014] Sweeper heating control information acquisition module: used to obtain the area and temperature of each ice area on the belt surface of the belt conveyor, analyze the severity of ice on the belt surface of the belt conveyor, and further obtain the sweeper heating control information, where the control information includes heating temperature and heating time, and provide feedback.

If adjustment is required, the adjustment information of the sweeper scraper contact pressure is obtained and feedback is provided. If adjustment is not required, the original contact pressure of the sweeper scraper is maintained.

[0016] Sweeper scraper wear monitoring and early warning module: used to obtain the change in contact angle and contact surface area between the sweeper scraper and the conveyor belt, and obtain the maximum deformation of the front profile of the sweeper scraper, analyze the degree of wear of the sweeper scraper, determine whether the sweeper scraper needs to be replaced, and issue an early warning.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1 As shown, the present invention provides a sweeper heating scraper control system based on artificial intelligence, including a sweeper scraper installation angle correction module, a sweeper heating start demand judgment module, a sweeper heating control information acquisition module, a sweeper scraper contact pressure control module, a sweeper scraper wear monitoring and early warning module, and a database.

[0038] The sweeper heating start-up demand judgment module is respectively connected to the sweeper scraper installation angle correction module and the sweeper heating control information acquisition module, the sweeper scraper contact pressure control module is respectively connected to the sweeper heating control information acquisition module and the sweeper scraper wear monitoring and early warning module, and the database is respectively connected to the sweeper scraper installation angle correction module and the sweeper scraper contact pressure control module.

[0039] The sweeper scraper installation angle correction module is used to collect the side image of the sweeper scraper after the belt conveyor sweeper is installed, obtain the installation angle of the sweeper scraper, and determine whether the installation angle of the sweeper scraper needs to be corrected. If correction is required, the correction information of the sweeper scraper installation angle is obtained, and the sweeper scraper installation distance adjustment information is further analyzed to provide feedback. If correction is not required, the original installation angle of the sweeper scraper is maintained.

[0040] Further, see Figure 3 and Figure 4 As shown, the specific process of judging whether the installation angle of the sweeper scraper needs to be corrected in the sweeper scraper installation angle correction module is: collecting the side image of the sweeper scraper after the belt conveyor sweeper is installed by a high-definition camera, obtaining the angle between the tangent of the outer surface contour line of the scraper passing through the front edge of the scraper in the side image of the sweeper scraper and the vertical reference line, and recording it as the installation angle of the sweeper scraper.

[0041] As a preferred solution, the range of the installation angle of the sweeper scraper is .

[0042] The reference installation angle of the belt conveyor sweeper scraper stored in the database is extracted, the installation angle of the sweeper scraper is compared with the reference installation angle, the difference between the installation angle of the sweeper scraper and the reference installation angle is obtained, and the difference is compared with a preset installation angle difference threshold. If the difference between the installation angle of the sweeper scraper and the reference installation angle is greater than the preset installation angle difference threshold, the installation angle of the sweeper scraper needs to be corrected. If the difference between the installation angle of the sweeper scraper and the reference installation angle is less than or equal to the preset installation angle difference threshold, the installation angle of the sweeper scraper does not need to be corrected, and the original installation angle of the sweeper scraper is maintained.

[0043] As a preferred solution, the difference between the installation angle of the sweeper scraper blade and the reference installation angle represents the absolute value of the difference between the installation angle of the sweeper scraper blade and the reference installation angle.

[0044] As a preferred solution, the threshold value of the difference between the installation angle of the sweeper scraper blade and the reference installation angle is a value close to zero. In a specific embodiment, the threshold value of the difference between the installation angle of the sweeper scraper blade and the reference installation angle is 1°.

[0045] Furthermore, the specific process of obtaining the correction information of the sweeper scraper installation angle in the sweeper scraper installation angle correction module is: comparing the installation angle of the sweeper scraper with the reference installation angle; if the installation angle of the sweeper scraper is greater than the reference installation angle, then the correction direction of the sweeper scraper installation angle is to decrease; if the installation angle of the sweeper scraper is less than the reference installation angle, then the correction direction of the sweeper scraper installation angle is to increase.

[0046] The difference between the installation angle of the sweeper blade and the reference installation angle is recorded as the correction amount of the sweeper blade installation angle.

[0047] According to the correction direction and correction amount of the installation angle of the sweeper blade, correction information of the installation angle of the sweeper blade is obtained.

[0048] Further, see Figure 5 As shown, the specific process of analyzing the sweeper scraper installation distance adjustment information in the sweeper scraper installation angle correction module is: the distance between the center point of the unloading roller cross section in the belt conveyor and the center point of the sweeper rotating rod cross section in the side image of the sweeper scraper is recorded as the installation distance of the sweeper scraper.

[0049] If the installation angle of the sweeper scraper is greater than the reference installation angle, the sweeper scraper is tilted forward and the installation distance of the sweeper scraper is too far. At this time, the adjustment direction of the sweeper scraper installation distance is to decrease. If the installation angle of the sweeper scraper is less than the reference installation angle, the sweeper scraper is tilted backward and the installation distance of the sweeper scraper is too close. At this time, the adjustment direction of the sweeper scraper installation distance is to increase.

[0050] Substitute the correction amount of the sweeper scraper installation angle into the preset relationship function between the sweeper scraper installation distance adjustment amount and the sweeper scraper installation angle correction amount to obtain the sweeper scraper installation distance adjustment amount.

[0051] According to the adjustment direction and adjustment amount of the installation distance of the sweeper scraper, the adjustment information of the installation distance of the sweeper scraper is obtained and feedback is performed.

[0052] As a preferred solution, based on the structural principle and geometric knowledge of the belt conveyor sweeper, the relationship between the change in the sweeper scraper installation distance and the change in the sweeper scraper installation angle is analyzed, and then the relationship function between the sweeper scraper installation distance adjustment amount and the sweeper scraper installation angle correction amount is obtained.

[0053] It should be noted that the scraper of the belt conveyor cleaner needs to be installed at a specific angle, and the cleaner scraper needs to maintain an appropriate installation distance so that the material can be effectively scraped off the belt. If the installation angle of the cleaner scraper is too large, the cleaner scraper will tilt forward and may not be able to clean effectively; if the installation angle of the cleaner scraper is too small, the cleaner scraper will tilt backward, which may cause the heel of the scraper to contact the belt, creating a gap between the belt and the scraper. The conveyed material is constantly accumulated in this gap, and this accumulation forces the scraper to leave the belt. Once the scraper is pushed away from the belt, a large amount of material will pass between the belt and the scraper, greatly increasing the wear of the scraper and the belt and reducing the cleaning efficiency.

[0054] It should be noted that the present invention monitors the installation angle of the sweeper scraper to determine whether the installation angle of the sweeper scraper needs to be corrected, obtains the correction information of the installation angle of the sweeper scraper and analyzes the installation distance adjustment information of the sweeper scraper, thereby ensuring the correct installation of the sweeper scraper, avoiding the poor installation angle of the sweeper scraper affecting its cleaning efficiency, thereby ensuring the cleaning effect of the sweeper.

[0055] The sweeper heating start requirement judgment module is used to obtain a thermal image of the belt surface of the belt conveyor to determine whether the belt surface of the belt conveyor is frozen. If it is frozen, the sweeper's heating unit needs to be started. If it is not frozen, the sweeper's heating unit does not need to be started.

[0056] Furthermore, the specific working process of the sweeper heating start demand judgment module is: obtaining a thermal imaging image of the belt surface of the belt conveyor through an infrared thermometer, obtaining the temperature of each temperature zone on the belt surface of the belt conveyor, and comparing it with the preset belt icing warning temperature. If the temperature of a certain temperature zone on the belt surface of the belt conveyor is lower than or equal to the belt icing warning temperature, then the temperature zone on the belt surface of the belt conveyor is recorded as an ice zone, and the ice zones on the belt surface of the belt conveyor are counted. If the temperature of a certain temperature zone on the belt surface of the belt conveyor is greater than the belt icing warning temperature, then the temperature zone on the belt surface of the belt conveyor is recorded as a non-icing zone.

[0057] If the number of iced areas on the conveyor belt surface is greater than zero, the conveyor belt surface is frozen and the heating unit of the cleaner is started; if the number of iced areas on the conveyor belt surface is zero, the conveyor belt surface is not frozen and there is no need to start the heating unit of the cleaner.

[0058] As a preferred solution, the temperature corresponding to the historical freezing of the belt surface of the belt conveyor is obtained and used as the belt freezing warning temperature.

[0059] In one embodiment, a belt conveyor cleaner has a heating pad device, which is mounted on a crossbeam of the cleaner.

[0060] As a preferred solution, the belt conveyor cleaner is made of metal and can transfer heat.

[0061] As a preferred option, see Figure 6 As shown in the figure, the system composition of the belt conveyor cleaner includes a scraper unit, a heating unit, a heat conduction unit, a temperature control unit, and a connection unit. The heating unit is heated by an electric heater, and the temperature control unit contains a temperature sensor, which can automatically adjust the power of the electric heater in the heating unit to achieve temperature control. The temperature control unit and the heating unit are connected by a cable and a connecting plug.

[0062] The sweeper heating control information acquisition module is used to obtain the area and temperature of each ice area on the belt surface of the belt conveyor, analyze the severity of ice on the belt surface of the belt conveyor, and further obtain the sweeper heating control information, where the control information includes the heating temperature and heating time, and provide feedback.

[0063] Furthermore, the specific working process of the sweeper heating control information acquisition module includes: obtaining the area and temperature of each temperature area on the belt conveyor surface according to the thermal imaging image of the belt conveyor belt surface, screening and obtaining the area and temperature of each ice area on the belt conveyor belt surface, and recording them as , Indicates The number of the icing area, .

[0064] By analyzing the formula φ = δ ∗ ln [ 1 + ∑ i = 1 n ( ϕ 1 ∗ s i ∗ ε Δ s + ϕ 2 ∗ ( T 0 − T i ) ∗ γ Δ T ) ] Get the severity of ice on the conveyor belt surface ,in represents the correction factor for the preset icing severity, Indicates the impact factor corresponding to the preset unit icing area. Indicates the preset belt icing warning temperature. , Indicates the impact factor corresponding to the unit difference between the preset icing area temperature and the belt icing warning temperature. Respectively represent the weight factors of the preset icing area and temperature, .

[0065] As a preferred solution, the correction factor of the icing severity has the effect of amplifying, reducing or rounding the icing severity, thereby facilitating calculation and analysis.

[0066] As a preferred solution, the weight factors of the ice area and temperature are set according to the importance of the ice area and temperature in assessing the severity of ice formation. In a specific embodiment, the weight factors of the ice area and temperature are 0.4 and 0.6 respectively.

[0067] In another specific embodiment, by collecting real-life images of the belt conveyor belt surface, it is determined whether the belt conveyor belt surface is frozen and the area of ​​each frozen area on the belt conveyor belt surface is obtained. The specific method is: a real-life image of the belt conveyor belt surface is collected by a high-definition camera, and the image is compared with a preset sample image of frozen belt conveyor belt surface. If the similarity between the image of a certain area on the belt conveyor belt surface and the sample image of frozen belt conveyor belt surface is greater than a set similarity threshold, the belt conveyor belt surface is frozen, and the area on the belt conveyor belt surface is recorded as a frozen area. The frozen areas on the belt conveyor belt surface are counted, and the area of ​​each frozen area on the belt conveyor belt surface is further obtained.

[0068] Furthermore, the specific working process of the sweeper heating control information acquisition module also includes: substituting the severity of icing on the belt surface of the belt conveyor into the preset relationship function between the severity of icing on the belt surface and the heating temperature and heating time of the sweeper, obtaining the heating temperature and heating time of the sweeper, obtaining the control information of the sweeper heating, and feeding it back to the temperature control unit of the sweeper.

[0069] As a preferred solution, the more severe the ice formation on the surface of the belt conveyor, the higher the heating temperature of the belt conveyor cleaner and the longer the heating time.

[0070] As a preferred solution, the belt conveyor cleaner heating has two working modes, one is to preheat for a certain period of time before cleaning, and the other is to clean while heating.

[0071] It should be noted that the sweeper in the present invention has functional modules such as heating, heat conduction and temperature control, and can be used in very cold environments. When the material on the conveyor belt is frozen or snow is mixed into ice, the sweeper automatically heats up and cleans the residual material on the conveyor belt, thereby improving the cleaning effect, thereby solving the problem of poor cleaning effect in the prior art under low temperature and extremely cold conditions.

[0072] The sweeper scraper contact pressure control module is used to determine whether the contact pressure of the sweeper scraper needs to be adjusted. If adjustment is required, the adjustment information of the sweeper scraper contact pressure is obtained and feedback is provided. If adjustment is not required, the original contact pressure of the sweeper scraper is maintained.

[0073] Furthermore, the specific working process of the sweeper scraper contact pressure control module is: obtaining the contact pressure between the sweeper scraper and the belt through the pressure sensor, and recording it as the contact pressure of the sweeper scraper.

[0074] The reference contact pressure of the belt conveyor sweeper scraper stored in the database is extracted, and the contact pressure of the sweeper scraper is compared with the reference contact pressure to obtain the difference between the contact pressure of the sweeper scraper and the reference contact pressure. If the difference between the contact pressure of the sweeper scraper and the reference contact pressure is greater than a preset contact pressure difference threshold, the contact pressure of the sweeper scraper needs to be adjusted; if the difference between the contact pressure of the sweeper scraper and the reference contact pressure is less than or equal to the preset contact pressure difference threshold, the contact pressure of the sweeper scraper does not need to be adjusted, and the original contact pressure of the sweeper scraper is maintained.

[0075] If the contact pressure of the sweeper scraper blade is greater than the reference contact pressure, the adjustment direction of the sweeper scraper blade contact pressure is to decrease. If the contact pressure of the sweeper scraper blade is less than the reference contact pressure, the adjustment direction of the sweeper scraper blade contact pressure is to increase.

[0076] The difference between the contact pressure of the sweeper blade and the reference contact pressure is used as the adjustment amount of the sweeper blade contact pressure.

[0077] According to the adjustment direction and adjustment amount of the contact pressure of the sweeper blade, the adjustment information of the contact pressure of the sweeper blade is obtained.

[0078] It should be noted that the contact pressure between the conveyor belt cleaner blade and the conveyor belt needs to be properly adjusted to ensure good cleaning effect while avoiding excessive wear.

[0079] It should be noted that if the contact pressure of the belt conveyor cleaner scraper is too high, the belt and the cleaner scraper will wear quickly. If the contact pressure of the belt conveyor cleaner scraper is too low, it will not be able to effectively remove the residue on the belt surface.

[0080] As a preferred solution, the contact pressure of the belt conveyor cleaner blade can be adjusted by a spring or air pressure system to ensure optimal balance.

[0081] The sweeper scraper wear monitoring and early warning module is used to obtain the change in the contact angle and contact surface area between the sweeper scraper and the belt conveyor belt, and to obtain the maximum deformation of the front profile of the sweeper scraper, analyze the degree of wear of the sweeper scraper, determine whether the sweeper scraper needs to be replaced, and issue an early warning.

[0082] Further, see Figure 7As shown, the specific working process of the sweeper scraper wear monitoring and early warning module is: the tangent line of the outer surface contour line of the scraper passing through the front edge of the scraper in the side image of the sweeper scraper is recorded as the first analysis straight line, the normal line of the arc surface of the belt conveyor belt passing through the front edge of the scraper in the side image of the sweeper scraper is obtained, and recorded as the second analysis straight line, and the angle between the first analysis straight line and the second analysis straight line is obtained, and recorded as the contact angle between the sweeper scraper and the belt of the belt conveyor.

[0083] The area of ​​the contact area between the working surface of the cleaner scraper and the arc surface of the belt is obtained, and recorded as the contact surface area between the cleaner scraper and the conveyor belt.

[0084] Obtain the changes in contact angle and contact surface area between the scraper blade and the conveyor belt, and record them as .

[0085] See also Figure 8 As shown, the contour line of the front edge of the sweeper scraper is obtained, and it is compared with the set reference contour line of the front edge of the sweeper scraper to obtain the maximum deformation of the front edge contour line of the sweeper scraper relative to the reference contour line, which is recorded as the maximum deformation of the front edge contour of the sweeper scraper and expressed as .

[0086] In a specific embodiment, after the front edge of the scraper blade of the belt conveyor cleaner is worn, the contour line of the front edge of the scraper blade is sawtooth-shaped, while the reference contour line of the front edge of the scraper blade is approximately a horizontal straight line.

[0087] It should be noted that the front edge of the belt conveyor cleaner scraper contacts the belt first. When the scraper is worn, the belt conveyor cleaner will rotate into the belt to maintain contact between the scraper and the belt. At this time, the contact angle and contact surface area between the belt conveyor cleaner scraper and the belt conveyor belt also change accordingly.

[0088] By analyzing the formula Get the degree of wear of the sweeper blade ,in A correction factor indicating the preset degree of wear, represents a natural constant, They represent the preset thresholds of the contact angle change, contact surface area change and front profile deformation of the scraper, respectively. They represent the weights of the preset contact angle change, contact surface area change and front profile deformation respectively. .

[0089] As a preferred solution, the correction factor of the wear degree has the effect of amplifying, reducing or rounding the wear degree, thereby facilitating calculation and analysis.

[0090] As a preferred solution, the weights of the contact angle change, the contact surface area change and the front profile deformation are set according to the importance of the scraper contact angle change, the contact surface area change and the front profile deformation in evaluating the scraper wear degree. In a specific embodiment, the weights of the contact angle change, the contact surface area change and the front profile deformation are 0.35, 0.3 and 0.35 respectively.

[0091] The degree of wear of the sweeper scraper is compared with a preset wear threshold. If the degree of wear of the sweeper scraper is greater than the preset wear threshold, the sweeper scraper needs to be replaced. If the degree of wear of the sweeper scraper is less than or equal to the preset wear threshold, the sweeper scraper does not need to be replaced.

[0092] It should be noted that when the scraper of the belt conveyor cleaner is worn, the cleaning efficiency will be reduced and the risk of material residue on the belt surface will increase.

[0093] It should be noted that the present invention analyzes the degree of wear of the sweeper scraper and evaluates the wear of the sweeper scraper by obtaining the change in the contact angle and contact surface area between the sweeper scraper and the belt conveyor belt, as well as the deformation of the front profile of the sweeper scraper, and then promptly replaces the severely worn scraper parts to ensure the continuous and effective cleaning performance of the sweeper.

[0094] The database is used to store a reference installation angle and a reference contact pressure of a scraper blade of a belt conveyor cleaner.

[0095] See also Figure 2 As shown, the present invention provides a sweeper heating scraper control method based on artificial intelligence, comprising the following steps: S1, sweeper scraper installation angle correction: collecting a side image of the sweeper scraper after the belt conveyor sweeper is installed, obtaining the installation angle of the sweeper scraper, and judging whether the installation angle of the sweeper scraper needs to be corrected. If correction is required, obtaining the correction information of the sweeper scraper installation angle, further analyzing the sweeper scraper installation distance adjustment information, and providing feedback. If correction is not required, maintaining the original installation angle of the sweeper scraper.
