Description

Technical Field

[0001] This invention relates to the field of grinding equipment control technology, and in particular to an intelligent pressurization and flexible protection system and method for grinding equipment. Background Technology

[0002] Floor grinding equipment is widely used in the grinding and leveling of concrete, marble, epoxy flooring, and other surfaces. It primarily achieves material removal and surface leveling through the pressure between the grinding disc and the floor. In actual operation, the grinding disc pressure usually needs to be adjusted according to the floor condition to ensure grinding efficiency and quality.

[0003] Most existing grinding equipment operates by using fixed pressure or manual pressure adjustment based on experience. This can meet basic construction needs when the ground is relatively flat. However, in actual projects, the ground often has macroscopic unevenness, local bumps or depressions. In this case, the fixed pressure method can easily lead to excessive or insufficient local force on the grinding disc, resulting in uneven grinding, increased equipment vibration, or even damage to the grinding disc.

[0004] Furthermore, the equipment load during grinding constantly changes with the hardness of the ground material, surface undulations, and grinding depth. Existing grinding equipment typically relies solely on motor overload protection or simple current monitoring for safety, lacking a comprehensive evaluation mechanism that considers multiple parameters such as motor current, grinding disc torque, speed, and pressure. This makes it difficult to accurately and promptly reflect the overall load status of the equipment. When the equipment is under high load, failure to adjust the pressure in time can easily lead to motor overload, accelerated wear of the transmission system, and even equipment damage.

[0005] Furthermore, the pressure regulation and load protection of existing grinding equipment are usually independent control components, lacking a unified and coordinated control mechanism, and thus unable to achieve linked regulation based on ground conditions and equipment load status. At the same time, existing equipment typically only activates protection when an overload has already occurred, lacking the ability to predict load change trends and making timely preventative adjustments difficult.

[0006] Therefore, how to construct a grinding equipment control system that can adaptively pressurize according to ground conditions, comprehensively evaluate and grade depressurize in conjunction with equipment load conditions, and also has the ability to predict overload trends, so as to improve grinding quality and enhance equipment operation safety, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to address the problems existing in the background art by proposing an intelligent pressurization and flexible protection system and method for grinding equipment.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligent pressurization and flexible protection system for grinding equipment, comprising: Ground condition sensing unit, used to collect ground condition parameters characterizing the flatness of the ground; The load status sensing unit is used to collect load parameters that characterize the operating status of the grinding equipment; The adaptive pressurization control unit, connected to the ground state sensing unit and the grinding actuator, is used to generate a ground fusion evaluation factor based on the ground state parameters. ), and based on the ground fusion evaluation factors ( Generate a pressurization command to adjust the pressure of the grinding actuator; The comprehensive load assessment unit, connected to the load status sensing unit and the adaptive pressurization control unit, is used to generate a comprehensive load index based on the load parameters. ); The graded coordinated pressure reduction unit, connected to the comprehensive load assessment unit and the adaptive pressure control unit, is used to adjust the pressure based on the comprehensive load index (…). The system generates and outputs pressure reduction control commands, and simultaneously feeds back the pressure reduction control status to the adaptive pressurization control unit to correct subsequent pressurization commands. The system uses the ground fusion evaluation factor ( ) and the comprehensive load index ( By combining the coupled calculations of the ground condition assessment, the feedback correction of the pressure reduction control state, and other methods, a collaborative closed-loop control architecture of "ground condition assessment - adaptive pressurization - load evaluation - graded pressure reduction - pressurization correction" is constructed.

[0009] Furthermore, the ground state sensing unit includes: The flatness detection module is used to collect the macroscopic flatness deviation of the ground. ) and local height difference ( ); The attitude detection module is used to collect the attitude compensation angle of the equipment body. ).

[0010] Furthermore, the adaptive pressurization control unit is used to perform a fusion function. Generate the ground fusion evaluation factors ( ).

[0011] Furthermore, the integrated load assessment unit is used to perform a fusion function. Generate the comprehensive load index ( ); in, For motor current, For grinding disc torque, The grinding disc rotation speed, This refers to the pressure of the grinding disc.

[0012] Furthermore, the integrated load assessment unit is also used to evaluate the ground fusion assessment factor ( The load parameters are used to generate the comprehensive load index. The weighting coefficients are dynamically adjusted when the time is right.

[0013] Furthermore, the hierarchical collaborative decompression unit uses a decompression ratio function. The pressure reduction ratio is determined, and the pressure reduction ratio varies with the comprehensive load index ( Monotonically increasing.

[0014] Furthermore, the system also includes a load trend prediction unit, used to determine whether the equipment is in a pre-overload state based on the changing trend of the load parameters.

[0015] Furthermore, the load trend prediction unit performs pre-overload determination using load change rate parameters, which include at least the motor current change rate and the grinding disc speed change rate.

[0016] Furthermore, when a pre-overload state is determined, the load trend prediction unit sends an early warning command to the hierarchical collaborative decompression unit to execute decompression control in advance.

[0017] A method for intelligent pressurization and flexible protection of grinding equipment, applied to the system described in any one of claims 1 to 9, comprising: S1.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention collects ground flatness deviation, local height difference, and equipment attitude information through a ground condition sensing unit, and generates a ground fusion evaluation factor. Based on this evaluation factor, it automatically generates a pressurization command, enabling the grinding equipment to dynamically adjust the grinding disc pressure according to the ground condition. This effectively avoids the problems of local over-grinding or under-grinding, and improves the uniformity of ground grinding and construction quality. This invention integrates and calculates multiple load parameters such as motor current, grinding disc torque, grinding disc speed, and grinding disc pressure through a comprehensive load assessment unit to generate a comprehensive load index. Compared with the traditional single current monitoring method, it can more comprehensively and accurately reflect the equipment's operating load status. This invention uses a graded collaborative pressure reduction unit to determine the pressure reduction ratio based on the comprehensive load index and to adjust the pressure of the grinding actuator in stages. This achieves gradual pressure reduction control as the load gradually increases, thereby effectively preventing the equipment from entering an overload state and improving the safety and stability of equipment operation. This invention feeds back the pressure reduction control status to the adaptive pressure increase control unit to correct subsequent pressure increase commands, thus forming a closed-loop collaborative control mechanism between pressure increase control and load protection. This avoids frequent fluctuations during pressure regulation and improves system control stability. This invention analyzes the rate of change of motor current and the rate of change of grinding disc speed through a load trend prediction unit, identifies pre-overload conditions in advance before the equipment enters the actual overload state, and executes pressure reduction control in advance, thereby achieving proactive and flexible protection for the equipment; This invention constructs a collaborative closed-loop control architecture of "ground condition evaluation - adaptive pressurization - load assessment - graded depressurization - pressurization correction", enabling grinding equipment to intelligently adjust according to ground conditions and equipment load conditions. This not only improves grinding efficiency and quality but also effectively reduces equipment failure risks, demonstrating good practical value and promising prospects for promotion.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 like Figure 1As shown, this embodiment provides an intelligent pressurization and flexible protection system for grinding equipment, suitable for grinding equipment on marble, concrete, and other surfaces. It enables adaptive pressurization based on surface conditions and flexible overload protection, effectively preventing equipment damage and uneven surface grinding. The specific structure is as follows: The system consists of a ground condition sensing unit, a load condition sensing unit, an adaptive pressurization control unit, a comprehensive load assessment unit, a graded collaborative depressurization unit, and a load trend prediction unit. Each unit achieves efficient data interaction through an industrial CAN bus. The core control chip of the system can be an STM32H743VIT6, the overall power supply is 24V DC, and the response delay is ≤100ms. It constructs a collaborative closed-loop control architecture of "ground condition evaluation - adaptive pressurization - load assessment - graded depressurization - pressurization correction", which effectively ensures the stability and safety of the grinding process.

[0022] The ground condition sensing unit is used to collect relevant parameters characterizing the flatness of the ground. Specifically, it includes a flatness detection module and an attitude detection module. The two work together to effectively ensure the comprehensiveness and accuracy of the ground condition parameter collection. Flatness detection module: A laser flatness detector (e.g., model ZL-3000) is installed 15cm in front of the grinding disc of the grinding equipment. The detection range covers the width of the equipment (1.2m), and the acquisition frequency is set to 10Hz to accurately collect the macroscopic flatness deviation of the ground. and local height difference Among them, macroscopic flatness deviation Defined as the maximum deviation between the actual ground contour and the ideal plane within a 3m range, in mm, with a data collection range of 0-50mm; local height difference. Defined as the difference between the highest and lowest points on the ground within a 5cm×5cm area, in mm, with a collection range of 0-20mm.

[0023] Attitude detection module: Employs an IMU (Inertial Measurement Unit) (e.g., model MPU6050), installed in the middle of the equipment body, used to acquire the attitude compensation angle of the equipment body. Including the forward and backward tilt angle of the fuselage ( ) and left and right tilt angles ( The unit is degrees, and the acquisition range is -10° to +10°. It can effectively compensate for the influence of the equipment's own attitude on parameter acquisition during the ground flatness detection process, and significantly improve the accuracy of ground condition evaluation.

[0024] The load status sensing unit is used to collect load parameters that characterize the operating status of the grinding equipment. It adopts a multi-sensor fusion acquisition method, and the specific configuration is as follows: Motor current sensor (e.g., model: ACS712-20A): connected in series in the power supply circuit of the grinding motor, used to collect the motor's operating current I, in A, with a collection range of 0-20A and an accuracy of ±0.1A; Torque sensor (e.g., model JN338): mounted on the grinding disc drive shaft, used to collect the grinding disc torque T, in N·m, with a collection range of 0-500 N·m and an accuracy of ±1 N·m; Speed ​​encoder (e.g., model: E6B2-CWZ6C): Installed on the output shaft of the grinding disc motor, used to acquire the grinding disc speed ω, in rad / s, with a acquisition range of 0-30 rad / s and an accuracy of ±0.1 rad / s; Pressure sensor (e.g., model: PT124G-111): Installed on the pressurizing cylinder of the grinding actuator, used to collect the grinding disc pressure P, in MPa, with a collection range of 0-10MPa and an accuracy of ±0.05MPa.

[0025] The data collected by the above sensors are converted by an A / D converter (e.g., model: ADS1256) and then synchronously transmitted to the integrated load assessment unit and the adaptive pressurization control unit to provide data support for the generation of subsequent control commands.

[0026] The adaptive pressurization control unit is connected to the ground condition sensing unit and the grinding actuator (pressurization cylinder). The core can use an STM32H743VIT6 control chip, which has a built-in preset fusion algorithm and pressurization control logic. The specific implementation process is as follows: Ground fusion evaluation factors Generation: via fusion function Generate ground fusion evaluation factors The fusion function uses a weighted summation algorithm, and the specific formula is as follows: In the formula, =50mm (maximum threshold for macroscopic flatness deviation) =20mm (maximum threshold for local height difference) =10° (Maximum threshold for attitude compensation angle); The value range is 0-1. The closer the value is to 1, the worse the ground flatness and the greater the equipment attitude deviation. The closer it is to 0, the better the flatness of the ground and the more stable the posture of the equipment.

[0027] Pressurization command generation: The adaptive pressurization control unit generates pressurization commands based on ground fusion evaluation factors. The system generates a pressure command to adjust the pressure of the grinding actuator (pressure cylinder), and outputs a control signal using PWM pulse width modulation to control the proportional relief valve (e.g., model: DBW10B) to adjust the cylinder pressure; the specific control logic is as follows: Preset reference pressure P=5MPa (suitable for flat ground), when At that time, the pressurization pressure is That is, slightly increase the pressure to ensure the grinding effect; when At that time, the pressurization pressure is That is, to appropriately reduce the pressure and avoid local overload; when At that time, the pressurization pressure is This significantly reduces pressure, achieving dual protection for both the equipment and the ground.

[0028] The comprehensive load assessment unit is connected to the load status sensing unit and the adaptive pressurization control unit, respectively. It can use the same STM32H743VIT6 control chip as the adaptive pressurization control unit, and is mainly used to generate a comprehensive load index based on load parameters. The weighting coefficients of the load parameters are dynamically adjusted, and the specific implementation process is as follows: Comprehensive load index Generation: via fusion function Generate comprehensive load index The fusion function uses a normalized weighted fusion algorithm, and the specific formula is as follows: In the formula, =20A (maximum allowable current of the motor) =500 N·m (maximum permissible torque of the grinding disc) =30 rad / s (rated rotational speed of the grinding disc) =10MPa (maximum allowable pressure); The initial weighting coefficients are set to 0.25, 0.3, 0.25, and 0.2 respectively, satisfying the following conditions: ; The value range is 0-1. The closer the value is to 1, the greater the equipment load and the closer it is to an overload state. The closer it is to 0, the lighter the equipment load and the smoother the operation.

[0029] Dynamic adjustment of weighting coefficients: The integrated load assessment unit is based on ground fusion evaluation factors. (Originally obtained from the adaptive pressurization control unit), the above weighting coefficients are dynamically adjusted. The adjustment logic is as follows: when... When the ground is level, keep the initial weights unchanged and focus on the pressure on the grinding disc. and torque The impact; when When the ground is moderately uneven, the weight is adjusted to... Increase motor current Weighting, timely detection of load fluctuations; when When the ground is severely uneven, adjust the weight as follows: Further increase motor current The weighting should prioritize avoiding overload risks.

[0030] The graded coordinated pressure reduction unit is connected to the comprehensive load assessment unit and the adaptive pressure control unit, respectively. Its core component is a proportional pressure reducing valve (e.g., model DR10-4-5X / 100Y), used to adjust pressure based on the comprehensive load index. The depressurization control command is generated and output, and the depressurization control status is fed back to the adaptive pressurization control unit to correct subsequent pressurization commands. The specific implementation process is as follows: Determination of decompression ratio: The graded coordinated decompression unit uses a decompression ratio function. Determine the pressure reduction ratio, which varies with the overall load index. Monotonically increasing, specifically defined as a piecewise function: In the formula, The pressure reduction ratio is the percentage that the current applied pressure needs to be reduced by; when When the value is less than 0.3, the load is within the normal range and no pressure reduction operation is performed.

[0031] Pressure reduction control and feedback correction: The graded collaborative pressure reduction unit adjusts the pressure reduction ratio according to the determined pressure reduction ratio. The system generates a pressure reduction control command to control the proportional pressure reducing valve to adjust the pressure of the pressurizing cylinder, achieving staged pressure reduction. Simultaneously, the actual pressure value after pressure reduction, the pressure reduction ratio, and other pressure reduction control status are fed back to the adaptive pressurizing control unit via the CAN bus. Based on this feedback information, the adaptive pressurizing control unit corrects the reference pressure in the next pressurizing command. The corrected formula is as follows: This ensures that subsequent pressurization commands are precisely matched with the current load status, avoiding repeated overload.

[0032] The load trend prediction unit is connected to the load status sensing unit and the hierarchical collaborative pressure reduction unit, respectively. It has a built-in trend prediction algorithm to determine whether the equipment is in a pre-overload state based on the changing trend of load parameters. The specific implementation process is as follows: Load change rate parameter acquisition: The load trend prediction unit acquires the rate of change of load parameters in real time, including at least the motor current change rate. and the rate of change of grinding disc speed ;in, This represents the change in motor current per unit time (100ms), expressed in A / s. This represents the change in the rotational speed of the grinding disc within a unit of time (100ms), expressed in rad / (s²).

[0033] Pre-overload determination: Preset pre-overload determination threshold: (Rapid rise in current) (Rapid decrease in rotational speed); when any of the above thresholds is met and the duration is ≥300ms, the equipment is determined to be in a pre-overload state; if the threshold is only briefly reached (<300ms), it is determined to be a load fluctuation and the pre-overload warning is not triggered.

[0034] Early warning and early pressure reduction: When the pre-overload state is determined, the load trend prediction unit sends an early warning command to the graded collaborative pressure reduction unit. The graded collaborative pressure reduction unit executes pressure reduction control in advance, with an early pressure reduction ratio of 15%, which is one level earlier than the normal graded pressure reduction. This effectively prevents the equipment from entering the actual overload state from the pre-overload state and further enhances the system's flexible protection capability.

[0035] Example 2 like Figure 2 As shown, S1. Collect ground condition parameters and equipment load parameters. After the grinding equipment is started, the ground condition sensing unit immediately begins operation: the flatness detection module collects the macroscopic flatness deviation of the ground at a frequency of 10Hz. and local height difference The attitude detection module synchronously collects the attitude compensation angle of the device body. All ground condition parameters are converted by an A / D converter and then transmitted to the adaptive pressurization control unit. Meanwhile, the load status sensing unit collects the motor current at a frequency of 10Hz. Grinding disc torque Grinding disc speed Grinding disc pressure The load parameters, after being converted by the A / D converter, are transmitted to the comprehensive load assessment unit and the load trend prediction unit, respectively. During the data acquisition process, the system uses a Kalman filter algorithm to filter the acquired parameters, effectively removing abnormal data (such as data outside the acquisition range or sudden changes), ensuring the accuracy and reliability of parameter acquisition.

[0036] S2, Generate ground fusion evaluation factors ( ) and pressurization command The adaptive pressurization control unit receives ground condition parameters collected by S1. , , Through the fusion function Calculate and generate ground fusion evaluation factors ; according to The value range is used to generate the corresponding pressurization command: preset reference pressurization pressure. ,when At that time, the pressurization pressure is ;when At that time, the pressurization pressure is ;when At that time, the pressurization pressure is ; The pressurization command is output to the proportional relief valve (DBW10B) of the grinding actuator in the form of a PWM pulse width modulation signal to adjust the pressure of the pressurization cylinder and realize adaptive pressurization based on the ground condition.

[0037] S3, Generate Comprehensive Load Index The integrated load assessment unit receives the load parameters collected by S1. First, based on the ground fusion evaluation factors (Obtained from the adaptive pressurization control unit), dynamically adjust the weighting coefficients of each load parameter. ; Through the fusion function Calculate and generate the comprehensive load index , The value range is 0-1, which is used to accurately characterize the current load status of the device.

[0038] S4. Generate pressure reduction control command The hierarchical collaborative load reduction unit receives the comprehensive load index generated by S3. According to the pressure reduction proportional function Determine the pressure reduction ratio: when 0.3 ≤ When <0.5, the pressure reduction ratio is 10%; when 0.5 ≤ When <0.7, the pressure reduction ratio is 30%; when When ≥0.7, the pressure reduction ratio is 50%; when If the value is less than 0.3, the pressure reduction operation will not be performed; The graded coordinated pressure reduction unit generates pressure reduction control commands based on a determined pressure reduction ratio, controlling the proportional pressure reduction valve to adjust the pressure of the pressurizing cylinder, thereby achieving graded pressure reduction; simultaneously, the load trend prediction unit monitors the load change rate in real time. If the condition is determined to be pre-overload, an early warning command is immediately sent to the graded collaborative decompression unit to perform a 15% decompression operation in advance.

[0039] S5, Feedback and correction of subsequent pressurization commands The graded collaborative pressure reduction unit feeds back information such as the actual pressure value after pressure reduction, pressure reduction ratio, and pressure reduction execution status to the adaptive pressure control unit via the CAN bus; The adaptive pressurization control unit adjusts the reference pressure in the next pressurization command based on this feedback information. The corrected formula is as follows: This ensures that subsequent pressurization commands are precisely matched with the current load and ground conditions. Repeat steps S1 to S5, based on the ground fusion evaluation factors. With comprehensive load index The coupled calculations and feedback corrections of the decompression control state form a collaborative closed-loop control of "ground condition evaluation - adaptive pressurization - load assessment - graded decompression - pressurization correction", ultimately realizing intelligent pressurization and flexible protection of the grinding equipment.

[0040] The system and method of this embodiment can adaptively adjust the pressurization pressure according to the flatness of the ground, effectively avoiding uneven ground grinding; through load assessment and graded pressure reduction, the risk of equipment overload can be effectively avoided; the load trend prediction function can provide early warning of pre-overload conditions, further improving the timeliness and flexibility of protection; the whole system responds quickly and controls precisely, is suitable for various types of ground grinding equipment, and has high practicality and promotion value.
