TECHNICAL FIELD

[0001] The present application relates to the field of automation control technology, in particular to a synchronous cutting and waste collection control method and system based on a hollow circular cutter. BACKGROUND

[0002] In modern industrial production, milling machines as key processing equipment are widely used in mechanical manufacturing, automobile industry, aerospace and many other fields, and bear the heavy responsibility of accurately processing various workpieces. Its machining precision and efficiency directly affect the quality and production cycle of products, and occupy a pivotal position in the entire manufacturing production chain. With the rapid development of manufacturing industry towards high precision, high efficiency and intelligentization, more stringent requirements are put forward for the performance of milling machines, especially in the aspects of cutting process and waste collection and treatment.

[0003] In the traditional milling process of graphite heat dissipation film, cutting and waste collection are often relatively independent links, and there are many problems. For example, if the waste generated during cutting cannot be collected in time and effectively, it will not only pollute the processing environment, but also may cause waste accumulation, affecting the continuity and stability of processing, and thus reducing the processing precision and efficiency. In the milling of some precision parts, if the fine waste particles adhere to the surface of the workpiece or enter the key components of the machine tool, it may cause serious consequences such as scratching of the workpiece surface and wear of the machine tool transmission components. Moreover, the traditional waste collection methods, such as simple suction or mechanical collection, are difficult to adapt to the characteristics of different types of waste and complex processing conditions, and are prone to problems such as waste blocking the collection pipeline and incomplete collection.

[0006] Obtaining workpiece cutting instructions and analyzing to obtain workpiece cutting information, the workpiece cutting information including dry and wet cutting information and waste particle information;

[0007] In the case that the dry-wet cutting information is wet cutting, the heating ring is controlled to heat at a first heating power to preheat the exhaust port, and the exhaust port is configured to a preset initial caliber according to waste particle information;

[0008] After the preheating is completed, the cutting operation is started and the negative pressure suction device is started synchronously, and during the cutting operation, an annular pressure distribution diagram of the exhaust passage inner wall is generated based on the data collected by the pressure sensor array in real time;

[0009] Whether there is an exhaust passage blockage is determined according to the pressure annular distribution diagram, and when it is determined that there is an exhaust blockage, a target blockage point pair is determined according to the pressure annular distribution diagram;

[0010] A target high-speed airflow jetting port is determined in the plurality of high-speed airflow jetting ports according to a direction of a point pair connecting line formed according to the target blockage point pair, wherein an extension direction of the high-speed airflow jetting port and the direction of the point pair connecting line satisfy a preset angle range;

[0011] The power of the heating ring is controlled to be raised to a second heating power, and the target high-speed airflow jetting port is controlled to jet high-speed airflow to unblock the exhaust port.

[0015] The initial caliber value is corrected according to the particle concentration information, and when the particle concentration is higher than a reference concentration, a preset concentration compensation amount is added to the initial caliber value to obtain the initial caliber;

[0016] The driving air bag is controlled to be inflated to a position corresponding to the caliber to complete the initial caliber configuration.

[0017] In a possible implementation, the annular pressure distribution diagram of the exhaust passage inner wall is generated based on the data collected by the pressure sensor array in real time, and includes:

[0018] The real-time pressure values of each pressure sensor in the pressure sensor array are collected at a preset frequency to obtain pressure time series data P1(t), P2(t),..., Pn(t) of each sensor, where n is the number of sensors, and t is a time stamp;

[0019] The pressure time series data of each sensor is filtered to eliminate pulse interference signals, and the filtering formula is: P i ' (t) = 0.7×P i (t) + 0.3×P i (t-1) where P i ' (t) is the filtered pressure value of the i-th sensor, P i (t-1) is the pressure value of the sensor at the previous time;

[0024] If there is at least one pair of high-pressure regions satisfying the region pair condition, it is determined that there is a substantial blockage of the exhaust passage;

[0025] If there is no pair of high-pressure regions satisfying the condition, it is determined that there is no substantial blockage.

[0026] In a possible implementation, when there are multiple pairs of high-pressure regions satisfying the region pair condition, the determining a target blockage point pair according to the ring-shaped pressure distribution map comprises:

[0027] From all the pairs of high-pressure regions satisfying the condition, a pair of regions with the largest total pressure is selected as a target blockage region pair, wherein the total pressure of a region pair is the sum of the average pressure values of the two high-pressure regions in the region pair;

[0028] In the target clogging area, a single sensing point with the maximum pressure value in each high-pressure area is selected respectively, and the two sensing points are determined as the final target clogging point pair.

[0029] In a possible implementation, the preset angle range is 75°-90°, and the target high-speed airflow jetting port is determined in the plurality of high-speed airflow jetting ports according to the direction of the line connecting the target clogging point pair, including:

[0030] The annular pressure distribution of the inner wall of the exhaust channel is updated in real time by the pressure sensing array at a preset sampling period;

[0031] The target clogging point pair is re-identified based on the updated pressure distribution, a new direction of the line connecting the point pair is calculated, and a current direction of the line connecting the point pair is obtained;

[0032] An angle deviation value is obtained by calculating the angle deviation between the current direction of the line connecting the point pair and the direction of the line connecting the point pair at the last sampling time;

[0033] If the angle deviation value is less than an angle threshold, it is determined that the clogging area has not shifted, and the current target high-speed airflow jetting port is maintained unchanged;

[0034] If the angle deviation value is greater than or equal to the angle threshold, it is determined that the clogging area has shifted, and a jetting port with an extension direction within the range of 75°-90° relative to the current direction of the line connecting the point pair is selected from the plurality of high-speed airflow jetting ports as a new target high-speed airflow jetting port.

[0035] In a possible implementation, the control of the heating ring power to the second heating power includes:

[0036] The heating ring power is controlled to the second heating power according to the pressure value corresponding to the target clogging point pair, and the second heating power has a positive correlation with the pressure value.

[0037] In a possible implementation, the method further includes:

[0038] After the target high-speed airflow jetting port is controlled to jet high-speed airflow for a preset time, if the exhaust channel clogging is still not removed, the driving air bag is controlled to expand and adjust the initial caliber.

[0039] In a possible implementation, after the driving air bag is controlled to expand and adjust the initial caliber, the method further includes:

[0040] A negative pressure compensation coefficient is determined according to the clogging duration;

[0041] The power of the negative pressure suction device is corrected according to the negative pressure compensation coefficient;

[0042] The calculation formula of the negative pressure compensation coefficient K is:

[0043] K= (D1 2 / D0 2 ) × (1 + μ×Δt), wherein D0 is an initial caliber, D1 is an enlarged caliber, μ is a time compensation coefficient, and Δt is a duration of the blockage.

[0044] The modified power P1 of the negative pressure suction device is P0×K, and P0 is an initial suction power.

[0045] In a second aspect, the embodiments of the present application further provide a milling machine system, comprising:

[0046] A hollow circular cutter, comprising a cutting part and a waste discharge port arranged at the center of the cutting part, an outer side of the waste discharge port is provided with a driving air bag for adjusting the opening size of the waste discharge port, and an inner wall of the waste discharge port is further provided with a pressure sensor array, a heating ring and a plurality of high-speed airflow injection ports.

[0047] A negative pressure suction device, which is in communication with the waste discharge port;

[0048] A memory, configured to store program code; and

[0049] A processor, configured to call the program code to execute the method according to the first aspect.

[0050] Unlike existing technologies, the synchronous cutting and waste collection control method based on a hollow circular cutter provided in this application first acquires the workpiece cutting command and parses it to obtain the workpiece cutting information, which includes dry and wet cutting information and waste particle information. When the dry / wet cutting information indicates wet cutting, the heating ring is controlled to heat the waste outlet at a first heating power to preheat it, and the waste outlet is configured to a preset initial diameter based on the waste particle information. After preheating, the cutting operation is started, and the negative pressure suction device is started simultaneously. During the cutting operation, the pressure sensor array monitors the process in real time. The collected data generates an annular pressure distribution map of the inner wall of the waste discharge channel. Then, based on this pressure annular distribution map, it is determined whether there is a blockage in the waste discharge channel. If a blockage is confirmed, the target blockage point pair is identified based on the pressure annular distribution map. Next, based on the direction of the line connecting the target blockage point pairs, a target high-speed airflow nozzle is identified among multiple high-speed airflow nozzles. The extension direction of the high-speed airflow nozzle and the direction of the line connecting the point pairs satisfy a preset angle range. Finally, the heating ring power is increased to a second heating power, and simultaneously, the target high-speed airflow nozzle is controlled to spray high-speed airflow to relieve the blockage in the waste discharge channel. Thus, this application utilizes a pressure sensor array to generate an annular pressure distribution map, enabling real-time and intuitive judgment of whether a blockage has occurred and precise location of the blockage point, significantly improving the timeliness and accuracy of blockage identification. Simultaneously, the combined strategy of increasing the heating ring power and spraying the target high-speed airflow utilizes high temperature to reduce the viscosity of the waste material and directs the directional high-speed airflow to the blockage point, achieving rapid and precise blockage relief, ensuring the continuous unobstructed flow of the waste discharge channel, and avoiding cutting interruptions or equipment failures caused by blockages.

[0061] In modern industrial production, milling machine tools, as key processing equipment, are widely used in many fields such as machinery manufacturing, automotive industry, and aerospace, undertaking the important task of precision machining of various workpieces. Their machining accuracy and efficiency directly affect product quality and production cycle, occupying a pivotal position in the entire manufacturing production chain. With the rapid development of manufacturing towards high precision, high efficiency, and intelligence, more stringent requirements are being placed on the performance of milling machine tools, especially in cutting processes and waste collection and handling.

[0062] In traditional milling processes, cutting and waste collection are often relatively independent steps, presenting numerous problems. For example, if waste generated during cutting is not collected promptly and effectively, it can not only pollute the processing environment but also lead to waste accumulation, affecting the continuity and stability of processing, thereby reducing processing accuracy and efficiency. In the milling of some precision parts, if fine waste particles adhere to the workpiece surface or enter critical components of the machine tool, they may cause serious consequences such as scratches on the workpiece surface and wear on machine tool transmission components. Moreover, traditional waste collection methods, such as simple suction or mechanical collection, are difficult to adapt to the characteristics of different types of waste and complex processing conditions, easily leading to problems such as waste clogging of collection pipes and incomplete collection.

[0063] To address the aforementioned technical problems, this application provides a synchronous cutting and waste collection control method based on a hollow circular cutter. This method can be applied to milling machine tool systems, such as... Figure 1 As shown, the milling machine tool system of this application includes a hollow circular cutter 100, a negative pressure suction device 200, and a waste collection device 300. The hollow circular cutter 100 includes a cutting part 110 and a waste discharge port 120 located at the center of the cutting part 110. The waste discharge port 120 is connected to the negative pressure suction device 200 through a waste discharge pipe 130. A driving airbag 140 for adjusting the opening size of the waste discharge port 120 is provided on the outer side of the waste discharge port 120. The inner wall of the waste discharge port 120 is also provided with a pressure sensing array, a heating ring, and multiple high-speed airflow jets (not shown in the figure).

[0064] The hollow circular cutter 100 serves as the core cutting component, used for milling the workpiece. The negative pressure suction device 200 provides negative pressure suction, allowing the waste generated during cutting to be drawn from the waste discharge port into the waste collection device 300, achieving simultaneous collection of waste.

[0065] More specifically, the cutting part 110 in this application directly contacts the workpiece to achieve the material cutting function. The waste discharge port 120 is the channel for waste discharge, which is connected to the negative pressure suction device 200 through the waste discharge pipe 130, providing a path for the transfer of waste from the cutting area to the negative pressure device. The driving airbag 140 is used to drive the adjustment of the opening size of the waste discharge port 120. The discharge port diameter can be adjusted according to the waste particle information to adapt to the waste discharge requirements under different working conditions. The pressure sensor array is used to collect the pressure data of the inner wall of the waste discharge channel in real time and generate a ring pressure distribution map to determine whether there is a blockage in the waste discharge channel. The interval angle of each sensor in the pressure sensor array can be 20 degrees or other angles, which can be configured according to requirements. The heating ring is used to preheat or power-up heating the waste discharge port to reduce the viscosity of the waste and prevent the waste from adhering and blocking the waste discharge channel. Multiple high-speed airflow jets are used to spray high-speed airflow directly to the blockage point when the waste discharge channel is blocked, which, together with the heating ring, achieves efficient blockage removal.

[0066] It should be noted that the pressure sensor array, heating ring, and multiple high-speed airflow nozzles mentioned above can be set at a distance of 1-20cm from the end of the exhaust port. For example, the heating ring can be set at a distance of 1cm from the end of the exhaust port, the pressure sensor array at a distance of 5cm from the end of the exhaust port, and the multiple high-speed airflow nozzles at a distance of 10cm-15cm from the end of the exhaust port.

[0067] like Figures 1-4 As shown, the following explanation uses a milling machine system as an example to illustrate this synchronous cutting and waste collection control method. It should be noted that although the logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order. Please refer to the appendix. Figure 2 The method includes the following steps S100-S600:

[0068] Step S100: Obtain the workpiece cutting command and parse the workpiece cutting information, wherein the workpiece cutting information includes dry and wet cutting information and waste particle information;

[0069] The dry / wet cutting information includes dry cutting, wet cutting, or a combination of both. Dry cutting refers to cutting tasks that do not require lubricant or coolant, suitable for cutting scenarios with low cooling and lubrication requirements. Wet cutting refers to cutting tasks that require lubricant or coolant, which can improve cutting accuracy and tool life through cooling and lubrication, suitable for high-load, high-precision cutting tasks. Dry / wet cutting dynamically switches between cooling and lubrication methods according to the different stages of the cutting process, and includes at least one cutting process that does not require lubricant / coolant and one cutting process that requires lubricant / coolant.

[0070] Waste particulate information is an expression of the characteristics of waste particles generated during the cutting process. Specifically, it can include the maximum diameter, average diameter, particle shape characteristics (blocky, flocculent, etc.), and particle concentration (amount of waste generated per unit time).

[0071] In actual production scenarios, workpiece cutting information can be obtained through a combination of manual configuration and system calculation. For example, operators can directly select the dry / wet cutting mode (e.g., wet cutting for high-hardness metal materials) on the milling machine's operating interface based on the physical properties of the material to be cut (such as hardness and thermal conductivity). Simultaneously, the operator inputs the cutting path parameters according to the processing requirements. The system will combine the original dimensions of the workpiece to be processed with the cutting amount of the cutting path to calculate and automatically deduce and determine the expected waste particle information, ensuring the accuracy and adaptability of the information acquisition and laying the foundation for subsequent processing.

[0072] Step S200: When the dry / wet cutting information is wet cutting, control the heating ring to heat with a first heating power to preheat the waste discharge port, and control the waste discharge port to be configured to a preset initial diameter according to the waste particle information.

[0073] If step S100 determines that a wet cutting mode is adopted, lubricant or coolant will be used during the cutting process, which is prone to adhering to the inner wall of the waste discharge port, potentially reducing the flowability of the waste material and affecting the waste discharge efficiency. Therefore, this application preheats the waste discharge port with a heating ring at a first heating power before the cutting operation starts, which can effectively reduce the adhesion of coolant or lubricant. Simultaneously, based on the expected waste particle information generated by the cutting task (such as particle diameter, morphology, and other key parameters), the waste discharge port is precisely adjusted to a preset initial diameter, laying the foundation for efficient waste discharge in the future.

[0074] It should be noted that the initial diameter is determined with the core principle of ensuring the waste discharge effect. For example, in order to ensure the wind speed required for negative pressure adsorption and to avoid waste blockage, the initial diameter only needs to be slightly larger than the maximum diameter of the waste particles, thus laying the foundation for efficient waste discharge in the future.

[0075] Step S300: After preheating is completed, start the cutting operation and simultaneously start the negative pressure suction device. During the cutting operation, the data collected in real time by the pressure sensor array generates an annular pressure distribution map of the inner wall of the waste discharge channel.

[0076] The determination of preheating completion can be achieved in the following two ways: First, a timed control strategy can be adopted, such as pre-configuring a fixed preheating time of 2 minutes. When the time is up, the preheating is determined to be complete and the cutting operation is automatically started. Second, a temperature feedback control strategy can be adopted, which collects the temperature of the exhaust port in real time through a temperature monitoring component. When the temperature reaches the preset temperature threshold, the cutting operation start process is automatically triggered.

[0077] At the same time as the cutting operation starts, the negative pressure suction device operates simultaneously. Through the negative pressure environment formed by the waste discharge channel and the waste discharge port, the waste generated during the cutting process is adsorbed into the waste collection device in real time, so as to realize the synchronous collection of waste.

[0078] It should be noted that, due to the differences in shape and size of the waste particles generated during cutting, and the randomness of their movement path under negative pressure adsorption, these waste particles are prone to blockage in the waste discharge port due to mutual compression, entanglement, or accumulation. Based on this, this application uses a pressure sensor array to collect pressure data from the inner wall of the channel in real time and converts the data into a ring-shaped pressure distribution map. This distribution map can intuitively reflect the pressure distribution status at different locations in the channel. By analyzing abnormal changes or characteristics in the pressure distribution, it is possible to accurately determine whether the waste discharge channel is blocked.

[0079] The waste discharge channel can refer to a waste discharge port or a waste discharge pipe connecting the waste discharge port to the negative pressure suction device. In one embodiment, the waste discharge pipe connecting the waste discharge port to the negative pressure suction device can be set to a larger diameter, so that this application only needs to form an annular pressure distribution diagram of the waste discharge port.

[0080] Step S400: Determine whether there is a blockage in the waste discharge channel based on the pressure ring distribution diagram, and if a blockage is found, determine the target blockage point pair based on the pressure ring distribution diagram.

[0081] Among them, the pressure distribution characteristics of the pressure ring distribution diagram can be used to determine whether there is a blockage in the waste discharge channel and what type of blockage it is.

[0082] Specifically, when the pressure ring distribution diagram shows an abnormal increase in pressure on one side of the channel, it can be directly identified as a unilateral local blockage. This type of blockage usually only affects the flow of waste in a local area and has little impact on the overall waste discharge efficiency. When the pressure ring distribution diagram shows an abnormal increase in pressure on both sides of the channel at the same time, it can be identified as a middle jamming blockage. The cause is that the waste on both sides of the blockage comes into contact with the inner wall of the channel, forming a middle congestion. This type of blockage easily leads to the continuous accumulation of waste in the middle of the channel. If it is not dealt with in time, it is very easy to develop into a global blockage, which will have a greater impact on the waste discharge system.

[0083] After initially determining the type of blockage, it is necessary to further locate the target blockage point pair using the distribution map: If only a pressure anomaly is detected on one side and no corresponding pressure anomaly area is found on the other side, then there is no target blockage point pair, and it can be clearly determined as a unilateral local blockage. Given its limited impact on the overall waste collection, there is no need to immediately implement intervention control, and it can be cleared autonomously by the natural flow of subsequent waste particles; If the distribution map clearly shows that there are pressure anomalies on both sides, that is, there is a target blockage point pair, then it is determined to be a middle-blockage type blockage. Since it will seriously hinder the waste discharge process, it is necessary to accurately locate the specific location of this point pair to provide an accurate positional reference for subsequent directional unblocking through high-speed airflow jets, thereby ensuring the targeted and effective unblocking operation.

[0084] Step S500: Determine the target high-speed airflow nozzle among the plurality of high-speed airflow nozzles according to the direction of the line connecting the point pairs formed by the target blockage points, wherein the extension direction of the high-speed airflow nozzle and the direction of the line connecting the point pairs satisfy a preset angle range.

[0085] After determining the target blockage point pair based on the pressure ring distribution diagram in step S400, it can be determined that the channel blockage is of the middle-blocking type. The significant feature of the middle-blocking type blockage is that the two sides of the blockage are against the inner wall of the waste discharge channel, and the direction of the line connecting the blockage center and the target blockage point pair is highly correlated.

[0086] Therefore, after identifying the target blockage point pair, the direction of the line connecting the point pair should be used as a reference to select target jet nozzles. For example, by setting a preset angle range constraint, it can be ensured that the selected target high-speed airflow jet nozzles can be accurately aligned with the core area of ​​the blockage.

[0087] Step S600: Control the heating ring power to increase to the second heating power, and at the same time control the target high-speed airflow nozzle to spray high-speed airflow to remove the blockage of the exhaust port.

[0088] After determining the target high-speed airflow nozzle in step S500, the heating ring power can be increased to the second heating power, and at the same time, the target high-speed airflow nozzle can be controlled to spray high-speed airflow to relieve the blockage of the exhaust port.

[0089] It is understandable that waste stuck in the middle is prone to forming a solid blockage due to stickiness or interlocking particles, and a single airflow impact may not be enough to completely clear it. Therefore, this application adopts a synergistic strategy of heating assistance and directional airflow impact. Specifically, controlling the heating ring power to increase to a second heating power can quickly raise the temperature of the waste outlet and the blockage area. On the one hand, this effectively reduces the stickiness of the waste, weakening the adhesion between waste particles and the adhesion between the waste and the inner wall of the channel; on the other hand, it causes the air in the blockage area to expand due to heat, indirectly enhancing the clearing effect of the airflow impact. Simultaneously with the increased heating ring power, the target high-speed airflow nozzle sprays high-speed airflow according to a preset pressure and duration. The airflow precisely acts on the core area of ​​the blockage. With the reduced stickiness of the waste due to heating, the airflow impact force can more efficiently blow and disperse the blockage, allowing the waste to be quickly discharged under negative pressure suction, achieving complete blockage removal.

[0090] For example, the heating ring power can be increased to a second heating power based on the pressure value corresponding to the target blockage point, where the second heating power is positively correlated with the pressure value. That is, the higher the pressure value corresponding to the target blockage point, the higher the value of the second heating power, thereby quickly increasing the local temperature at the blockage point, accelerating the melting or unblocking of the blockage, and improving the unblocking efficiency and effect.

[0091] Based on this, the synchronous cutting and waste collection control method based on a hollow circular cutter provided in this application first obtains the workpiece cutting command and parses it to obtain the workpiece cutting information, which includes dry and wet cutting information and waste particle information. When the dry / wet cutting information indicates wet cutting, the heating ring is controlled to heat the waste outlet with a first heating power to preheat it, and the waste outlet is configured to a preset initial diameter based on the waste particle information. After preheating, the cutting operation is started and the negative pressure suction device is started simultaneously. During the cutting operation, the pressure sensor array collects data in real time. The data generates an annular pressure distribution map of the inner wall of the waste discharge channel. Then, based on the pressure annular distribution map, it is determined whether there is a blockage in the waste discharge channel. If a blockage is confirmed, the target blockage point pair is determined based on the pressure annular distribution map. Next, based on the direction of the line connecting the target blockage point pair, a target high-speed airflow nozzle is determined among multiple high-speed airflow nozzles. The extension direction of the high-speed airflow nozzle and the direction of the line connecting the point pair satisfy a preset angle range. Finally, the heating ring power is increased to a second heating power, and simultaneously, the target high-speed airflow nozzle is controlled to spray high-speed airflow to relieve the blockage in the waste discharge channel. Thus, this application utilizes a pressure sensor array to generate an annular pressure distribution map, enabling real-time and intuitive judgment of whether a blockage has occurred and precise location of the blockage point, significantly improving the timeliness and accuracy of blockage identification. Simultaneously, the combined strategy of increasing the heating ring power and spraying the target high-speed airflow utilizes high temperature to reduce the viscosity of the waste material and directly applies directional high-speed airflow to the blockage point, achieving rapid and precise blockage relief, ensuring continuous unobstructed flow in the waste discharge channel, and avoiding cutting interruptions or equipment failures caused by blockages.

[0092] In one embodiment, the step of controlling the configuration of the waste discharge port to a preset initial diameter based on the waste particulate matter information includes:

[0093] The initial aperture base value is set according to the maximum particle diameter to reserve a safe flow gap, wherein the base value is not less than a preset multiple of the maximum particle diameter;

[0094] The base value is adjusted according to the particle shape characteristics. For irregular particles, a preset compensation amount is added to the base value to obtain the initial caliber value.

[0095] The initial aperture value is corrected based on the particle concentration information. When the particle concentration is higher than the reference concentration, a preset concentration compensation amount is added to the initial aperture value to obtain the initial aperture.

[0096] Control the inflator to inflate to the position corresponding to the diameter, and complete the initial diameter configuration.

[0097] Specifically, firstly, an initial baseline diameter is set based on the maximum diameter of the waste particles. This baseline value serves as a safety clearance for the waste outlet. The baseline value must be no less than a preset multiple of the maximum particle diameter (e.g., 1.1 times). This setting ensures that particles with the maximum diameter will not clog the waste outlet due to an insufficient diameter, providing a basic reference for subsequent diameter adjustments. Next, the baseline value is adjusted based on the particle shape characteristics. For irregular particles, which may have protrusions or sharp edges, a preset compensation amount is added to the baseline value to obtain an initial diameter setting, thus adapting to the special shape of irregular particles and further reducing the risk of clogging. Then, the initial diameter setting is corrected based on particle concentration information. When the particle concentration is higher than the baseline concentration, it indicates that more particles pass through the waste outlet per unit time. To avoid particle accumulation and clogging, a preset concentration compensation amount is added to the initial diameter setting to obtain the final initial diameter. Finally, the control airbag is inflated to the position corresponding to the initial diameter, completing the initial diameter configuration of the waste discharge port. The diameter can be precisely adjusted by the airbag drive to ensure that the configured diameter meets the actual waste discharge requirements.

[0098] Thus, the embodiments of this application can reasonably determine the initial diameter of the waste discharge port and complete the configuration based on the waste particulate matter information, thereby ensuring the smooth discharge of waste particles and improving waste discharge efficiency.

[0099] In one embodiment, the step of generating an annular pressure distribution map of the inner wall of the waste discharge channel using data collected in real time by the pressure sensing array includes:

[0100] Each pressure sensor in the control pressure sensor array collects real-time pressure values ​​at a preset frequency, obtaining pressure time-series data P1(t), P2(t), ..., Pn(t) for each sensor, where n is the number of sensors and t is the timestamp;

[0101] The pressure time-series data from each sensor are filtered to remove pulse interference signals. The filtering formula is: P i '(t) = 0.7×P i (t) + 0.3×P i (t-1) where P i '(t) represents the pressure value of the i-th sensor after filtering, P i (t-1) represents the pressure value of the sensor at the previous moment;

[0102] With the axis of the waste discharge port as the center, and the installation angle of each sensor as the polar angle, the filtered pressure value P i '(t) is used as the polar radius, and an annular pressure distribution map is generated by polar coordinate interpolation algorithm with an interpolation interval of 5°-10°.

[0103] Specifically, firstly, each pressure sensor in the pressure sensor array is controlled to collect real-time pressure values ​​at a preset frequency, obtaining the pressure time series data P1(t), P2(t), ..., Pn(t) of each sensor, where n is the number of sensors and t is the timestamp. By collecting data at regular intervals, the pressure dynamics at different locations on the inner wall of the waste discharge channel can be captured in real time, providing a continuous raw data basis for subsequent pressure distribution analysis.

[0104] The pressure time-series data from each sensor were then filtered to remove pulse interference signals. The filtering formula used was P. i '(t) = 0.7×P i (t) + 0.3×P i (t-1), where P i '(t) represents the pressure value of the i-th sensor after filtering, P i (t-1) represents the pressure value of the sensor at the previous moment. This weighted filtering method based on data from previous and subsequent moments can effectively smooth out instantaneous interference pulses, making the pressure data more closely match the actual pressure change trend.

[0105] Next, using the axis of the waste discharge port as the center, the actual installation angle of each sensor is used as the polar angle reference, and the filtered pressure value P is... i '(t) is used as the polar radius to generate a ring-shaped pressure distribution map using a polar coordinate interpolation algorithm. The interpolation interval here is set at 5°-10°, which is a refinement based on the actual layout angle of the sensors: the installation angle of the sensors determines the sampling nodes of the original data, while the interpolation interval of 5°-10° supplements the calculation of the pressure value at the intermediate angle in the angular gap between adjacent sensors. This ensures the accuracy of the data benchmark based on the actual layout of the sensors, and fills the angular gaps through reasonable interpolation intervals, making the ring-shaped pressure distribution more continuous and delicate. It can reflect the real pressure change trend and avoid data redundancy caused by overly dense interpolation or loss of details caused by overly sparse interpolation.

[0106] It should be noted that the filtering method used in the embodiments of this application is a time-series-based weighted sliding filter, and the formula is P. i '(t) = 0.7×P i (t) + 0.3×P i (t-1), its core principle is to smooth out instantaneous pulse interference by fusing pressure data from the current moment and the previous moment. From a computational perspective, this formula uses the raw pressure value P collected by the sensor at the current moment. i (t) is the primary reference (70% weight), combined with the filtered pressure value P from the previous time step. i(t-1) (weighted at 30%), the current filtering result P is obtained by weighted summation. i The reason for this design is that the raw data at the current moment reflects the latest pressure changes, and giving it a higher weight ensures the timeliness of the data; while introducing the filtered value from the previous moment as a reference can effectively suppress sudden pulse interference. When instantaneous abnormal fluctuations occur (such as spike signals generated by particle impacts on the sensor), the stable data from the previous moment will neutralize some of the interference, making the filtered result closer to the actual pressure change trend.

[0107] Thus, the data collected in real time by the pressure sensor array in this embodiment can generate an accurate and continuous annular pressure distribution map of the inner wall of the waste discharge channel, providing a reliable visual basis for subsequent judgment of blockage location and analysis of blockage degree, thereby improving the status monitoring accuracy of the waste discharge system.

[0108] In one embodiment, such as Figure 3 As shown, step S400: Determining whether there is blockage in the waste discharge channel based on the pressure ring distribution diagram includes:

[0109] S410. In the annular pressure distribution map, identify all continuous areas where the pressure values ​​exceed the pressure threshold and mark them as high-pressure areas.

[0110] S420. Traverse all the high-voltage regions and determine whether there are two high-voltage regions that satisfy the region pair condition, wherein the region pair condition includes that the arc distance between the center points of the two high-voltage regions is greater than a distance threshold.

[0111] S430. If at least one pair of high-voltage regions satisfies the region pair condition, it is determined that there is a substantial blockage in the waste discharge channel.

[0112] S440. If there is no high-pressure area pair that meets the conditions, it is determined that there is no substantial blockage.

[0113] Specifically, in the annular pressure distribution map, all continuous areas where the pressure value exceeds the preset pressure threshold are first identified and marked as high-pressure areas. The appearance of these high-pressure areas usually indicates that the corresponding location of the waste discharge channel may have abnormal pressure due to waste accumulation and compression, providing preliminary area identification for judging blockage.

[0114] Then, all marked high-pressure areas are traversed to determine if two high-pressure areas satisfy the area pairing condition. Specifically, the area pairing condition includes an arc distance between the center points of the two high-pressure areas that is greater than a set distance threshold. This arc distance is calculated with the waste discharge channel axis as the center and essentially reflects the circumferential spacing between the two high-pressure areas. When the two high-pressure areas are far apart, it indicates that the waste may have formed a relatively symmetrical compression state within the channel, or more likely, a substantial blockage causing overall channel obstruction.

[0115] Next, if at least one pair of high-pressure areas meets the above area pairing conditions, it is determined that there is a substantial blockage in the waste discharge channel. This is because such high-pressure areas often correspond to a relatively stable blockage structure formed by waste within the channel, resulting in continuous compression on both sides of the channel's circumference, which is a blockage state requiring intervention.

[0116] If no high-pressure area pair meets the criteria, it is determined that there is no substantial blockage. For example, a single high-pressure area may only be a local pressure increase caused by a brief particle impact, or multiple high-pressure areas concentrated in one area (with a small arc distance) may be local particle accumulation without forming an overall blockage. These situations usually do not require emergency clearing treatment.

[0117] Thus, by analyzing the characteristics of the high-pressure area in the annular pressure distribution diagram, this embodiment of the application can accurately determine whether there is a substantial blockage in the waste discharge channel, providing a basis for subsequent targeted unblocking operations, thereby improving the accuracy of the blockage response and processing efficiency of the waste discharge system.

[0118] In one embodiment, when multiple high-pressure area pairs satisfy the area pair conditions, the step of determining the target blockage point pair based on the pressure ring distribution map includes:

[0119] From all high-pressure area pairs that meet the conditions, the area pair with the largest total pressure is selected as the target blockage area pair; wherein, the total pressure of an area pair is the sum of the average pressure values ​​of the two high-pressure areas in the area pair;

[0120] In the target blockage area pair, select the single sensing point with the largest pressure value in each high-pressure area, and determine these two sensing points as the final target blockage point pair.

[0121] Specifically, when multiple high-pressure area pairs meet the pairing condition (i.e., the arc distance between the center points of two high-pressure areas is greater than a distance threshold), the pair with the largest total pressure is selected as the target blockage area pair from all high-pressure area pairs that meet the condition. The total pressure of the pair is defined as the sum of the average pressure values ​​of the two high-pressure areas in the pair. The average pressure value of a high-pressure area directly reflects the compressive strength of the waste accumulation in that area; the higher the average pressure, the more severe the blockage at the corresponding location. By summing the average pressures of the two areas and comparing them, the overall blockage strength of a pair of high-pressure areas can be comprehensively assessed. The pair with the largest total pressure indicates that the waste congestion at its location is the most stable and the compressive effect is the strongest. It is the core area causing substantial blockage of the waste discharge channel. Using it as the target blockage area pair can achieve precise location of key blockages, providing a core target for subsequent targeted dredging. For example, if there are two pairs of high-pressure areas, AB and CD, that meet the conditions, with average pressure of 0.8 MPa in area A, 0.7 MPa in area B, and a total of 1.5 MPa in area C, and 0.6 MPa in area D, and a total of 1.2 MPa in area D, then AB should be selected as the target blockage area pair.

[0122] Subsequently, within the identified target blockage area pair, the single sensor point with the highest pressure value in each high-pressure area is selected, and these two sensor points are designated as the final target blockage point pair. This is because the pressure distribution within each high-pressure area is not completely uniform; the sensor point with the highest pressure value corresponds to the specific location within that area where waste accumulation is most concentrated and compressive stress is most concentrated—the "core point" of the blockage. By locating the core points of two high-pressure areas to form a point pair, the blockage location can be precisely refined from the "regional level" to the "point level," ensuring that subsequent unblocking operations (such as high-speed air jetting) can directly target the most severely blocked critical points, significantly improving the targeting and efficiency of unblocking, and avoiding incomplete unblocking or resource waste due to deviations in the application location.

[0123] Thus, in the case of multiple effective high-pressure area pairs, the hierarchical strategy of area intensity sorting and precise point location can quickly lock the most critical target blockage point pairs, providing a reliable basis for subsequent precise dredging operations, thereby further improving the accuracy and efficiency of blockage treatment in the waste discharge system.

[0124] In one embodiment, the extension direction of the high-speed airflow nozzle and the direction of the line connecting the point and the nozzle satisfy a preset angle range of 75°-90°, such as... Figure 4 As shown, step S500: determining the target high-speed airflow nozzle among the plurality of high-speed airflow nozzles according to the direction of the line connecting the point pairs formed by the target blockage point pairs, including:

[0125] S510. The annular pressure distribution map of the inner wall of the waste discharge channel is updated in real time through the pressure sensor array at a preset sampling period.

[0126] S520. Based on the updated pressure distribution map, re-identify the target blockage point pairs, calculate the new connection direction of the point pairs, and obtain the current connection direction of the point pairs.

[0127] S530. Calculate the angle deviation between the current point-pair connection direction and the point-pair connection direction at the previous sampling time to obtain the angle deviation value.

[0128] S540. If the angle deviation value is less than the angle threshold, it is determined that the blockage area has not shifted, and the current target high-speed airflow nozzle is kept unchanged.

[0129] S550. If the angle deviation value is greater than or equal to the angle threshold, it is determined that the blockage area has shifted. Then, a new target high-speed airflow jet is selected from multiple high-speed airflow jets whose extension direction is within 75°-90° of the line connecting the current point pair.

[0130] Specifically, the annular pressure distribution map on the inner wall of the waste discharge channel is first updated in real time using a pressure sensor array at a preset sampling period. The preset sampling period can be adjusted according to the actual operation of the waste discharge system, ensuring timely capture of changes in the location of the blockage area while avoiding data redundancy and waste of system resources due to overly frequent sampling, thus providing continuous pressure data support for subsequent dynamic tracking of the blockage location.

[0131] Subsequently, based on the updated annular pressure distribution map, the current target blockage point pairs are re-identified using the method described above for determining target blockage point pairs. The direction of the new line connecting these two points is then calculated to obtain the current direction of the line connecting the points. Since waste materials may shift in position during the discharge process due to airflow or gravity, causing changes in the core blockage area, re-identifying the point pairs and calculating the connecting direction allows for real-time monitoring of the latest blockage location, providing precise directional guidance for the dynamic adjustment of the injection nozzle.

[0132] Next, the angular deviation between the current point-to-point line direction and the point-to-point line direction at the previous sampling time is calculated to obtain the angular deviation value. This angular deviation value is the core indicator for judging whether the blockage area has shifted significantly. Its calculation can be achieved through the vector angle formula or angle measurement algorithm, and it can intuitively reflect the degree of positional change of the core blockage area in the circumferential direction.

[0133] If the calculated angle deviation is less than the preset angle threshold, it is determined that the blockage area has not shifted. At this time, the extension direction of the current target high-speed airflow nozzle is still within the preset effective angle range of 75°-90° with the direction of the point-to-point line. This angle range ensures that the high-speed airflow impacts the blockage at the optimal angle, avoiding both the dispersion of impact force due to an excessively small angle and the reflection of airflow due to an excessively large angle. Maintaining the nozzle unchanged ensures the continuity and stability of the unblocking effect, and it can efficiently act on the blockage area without additional adjustments.

[0134] If the angle deviation is greater than or equal to the angle threshold, it is determined that the blockage area has shifted significantly. The angle between the extension direction of the original target high-speed airflow nozzle and the direction of the line connecting the current point and the target may exceed the effective range of 75°-90°, leading to a decrease or even failure in the unblocking effect. In this case, it is necessary to re-select from multiple high-speed airflow nozzles and choose the nozzle whose extension direction is within the range of 75°-90° as the new target high-speed airflow nozzle. This ensures that the adjusted nozzle can always apply impact force to the shifted core blockage area at the optimal angle, guaranteeing the effectiveness of the unblocking effect.

[0135] Thus, this application embodiment, through a closed-loop strategy of real-time sampling and updating, direction calculation and comparison, and dynamic adjustment of the jet nozzle, combined with the optimal angle constraint of 75°-90°, can accurately track the positional changes of the blockage area and match the most suitable target high-speed airflow jet nozzle, thereby improving the dynamic adaptability and efficiency of blockage clearing.

[0136] It should be noted that this application does not prioritize expanding the exhaust outlet diameter when congestion is detected, to avoid affecting the overall exhaust effect due to diameter expansion, such as preventing a decrease in adsorption wind speed caused by diameter expansion, thereby weakening the overall exhaust efficiency. Instead, this application only expands the initial diameter of the exhaust outlet when the aforementioned blockage relief solution has not taken effect.

[0137] For example, if the blockage in the exhaust channel is not cleared after a preset time (e.g., 1 minute) following the injection of high-speed airflow from the target high-speed airflow nozzle, the drive airbag is controlled to increase the initial diameter.

[0138] As described above, increasing the diameter of the exhaust outlet is not the optimal choice, as it will reduce the adsorption velocity and weaken the overall exhaust efficiency. Therefore, under certain circumstances, to mitigate the risk of reduced exhaust efficiency caused by increasing the outlet diameter, the output power of the negative pressure suction device can be adjusted according to the size of the outlet adjustment.

[0139] In one embodiment, after controlling the driving airbag to enlarge the initial diameter, the method further includes: determining a negative pressure compensation coefficient based on the duration of the blockage; and correcting the power of the negative pressure suction device based on the negative pressure compensation coefficient; wherein the formula for calculating the negative pressure compensation coefficient K is: K = (D1) / K. 2 / D0 2 ) × (1 + μ×Δt), where D0 is the initial diameter, D1 is the enlarged diameter, μ is the time compensation coefficient, and Δt is the duration of blockage; the corrected power of the negative pressure suction device is P1 = P0×K, where P0 is the initial suction power.

[0140] Specifically, after controlling the drive airbag to enlarge the initial diameter, the negative pressure compensation coefficient needs to be determined based on the duration of the blockage. The longer the blockage lasts, the tighter the interlocking and adhesion between waste particles may be, resulting in a more stubborn blockage. Therefore, it is necessary to compensate the negative pressure using time-dimensional parameters to provide a dynamic basis for subsequent power correction.

[0141] The power of the negative pressure suction device is then adjusted based on the negative pressure compensation coefficient, K, calculated as K = (D1² / D0²) × (1 + μ×Δt). μ is defined as the time compensation coefficient, which measures the impact of blockage duration on compensation intensity. A larger μ value indicates a more significant increase in the compensation coefficient as the blockage duration Δt lengthens, meaning a stronger suction effect for prolonged blockages. For example, when μ is 0.02 / min, a blockage lasting 10 minutes will cause the time compensation term (1 + μ×Δt) to reach 1.2, while when μ is 0.05 / min, the coefficient can reach 1.5 for the same duration, demonstrating a stronger tendency to handle stubborn blockages. This coefficient needs to be pre-calibrated based on the characteristics of the waste material (such as viscosity and hardness) and the channel material to ensure that the time compensation matches the actual degree of blockage stubbornness.

[0142] Finally, the corrected power of the negative pressure suction device is P1 = P0 × K (P0 is the initial suction power). Using this formula, when the orifice diameter increases (D1 > D0), the (D1² / D0²) term first compensates for the decrease in suction power per unit area caused by the increased orifice diameter. Simultaneously, as the duration of the blockage Δt increases, the μ×Δt term further increases the compensation coefficient, allowing P1 to be additionally increased beyond compensating for the orifice diameter loss. This ensures stronger suction power is applied to blockages that have remained blocked for extended periods, thereby achieving rapid unblocking and discharge of long-accumulated waste.

[0143] Thus, by introducing a time compensation coefficient, this embodiment of the application constructs a negative pressure compensation mechanism that takes into account both the change in diameter and the degree of blockage, making the suction power correction more consistent with the actual blockage state and effectively improving the adaptability of the waste discharge system to complex blockage scenarios.
