Description

Technical Field

[0001] This invention relates to the field of concrete vibration technology, specifically to an intelligent vibrator system and an intelligent vibration process. Background Technology

[0002] Concrete vibration is a crucial process in building construction. Its function is to eliminate air bubbles within the concrete and ensure uniform and dense material compaction, directly affecting the final strength and durability of the structure. Traditional vibration operations rely heavily on the operator's experience to control insertion depth, vibration time, vibration frequency, and vibrator lifting speed. This makes construction quality prone to fluctuations, under-vibration or over-vibration, and difficult to achieve traceable and standardized management. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes an intelligent vibrating rod system and an intelligent vibration process.

[0004] The technical solution adopted in this invention is as follows: In a first aspect, the present invention proposes an intelligent vibratory tamping rod system, comprising a vibratory tamping rod and a motor disposed inside the head of the vibratory tamping rod, and further comprising a control module electrically connected to the vibratory tamping rod; the control module comprises a motor control unit, a motor monitoring unit, a floating voltage detection unit, and an identification and analysis unit; the floating voltage detection unit is connected to the housing of the vibratory tamping rod and is used to detect the floating voltage of the housing relative to ground; the motor monitoring unit is used to monitor the input electrical signal of the motor; the identification and analysis unit is connected to the floating voltage detection unit and the motor monitoring unit and is used to determine the working stage of the vibratory tamping rod based on the changing trends of the floating voltage and the input electrical signal, and to identify and record the nodes between each working stage; the identification and analysis unit is connected to the motor control unit and is used to output control commands to the motor control unit based on the identified working stage and node.

[0005] As a preferred embodiment of the present invention, it further includes a detection conductor, which is disposed above the head of the vibrating rod, and the height difference between the detection conductor and the head is the set depth to which the vibrating rod needs to be inserted into the concrete; the floating voltage detection unit is connected to the detection conductor and is used to detect the floating voltage of the detection conductor; the shell of the vibrating rod is a metal conductor.

[0006] As a preferred embodiment of the present invention, it further includes a vibration sensor and an attitude sensor, which are respectively connected to the identification and analysis unit for real-time detection of the vibration data and attitude data of the vibrating rod.

[0007] As a preferred embodiment of the present invention, it further includes at least one of an audible and visual alarm and a visual medium, wherein the audible and visual alarm, the visual medium, and the identification and analysis unit are connected by wire or wireless means; the identification and analysis unit is configured to communicate with the control system of an external lifting device.

[0008] Secondly, this invention proposes an intelligent vibration process using the aforementioned intelligent vibrator system, comprising the following steps: S1: The floating voltage of the vibratory rod shell is detected by the floating voltage detection unit, and the input electrical signal of the motor is monitored by the motor monitoring unit; S2: The identification and analysis unit determines the working stage of the vibrator based on the changes and trends of the suspension voltage and the input electrical signal, and records the time of reaching each stage node. The working stages include the standby stage, the insertion stage, the vibration stage, and the withdrawal stage; the stage nodes include the insertion start node, the vibration start node, the withdrawal start node, and the final end node. S3: The identification and analysis unit outputs corresponding control commands to the motor control unit based on the determined working stage and the identified stage node to control the motor's working parameters.

[0009] As a preferred technical solution of the present invention, step S2 specifically includes: the initial working stage of the vibrator is the standby stage; when the suspension voltage of the shell drops below the first threshold and the input electrical signal begins to rise, the identification and analysis unit determines and records the time point when the suspension voltage drops below the first threshold as the insertion start node, and enters the insertion stage; when the input electrical signal changes from a decreasing or increasing trend to a stable state, the identification and analysis unit determines and records the current time point as the vibration start node, and enters the vibration stage; when the input electrical signal changes from a stable state to a decreasing trend, the identification and analysis unit determines and records the current time point as the vibration end node, and enters the pull-out stage; when the suspension voltage of the shell recovers to above the first threshold and the input electrical signal drops to the no-load range and stabilizes, the identification and analysis unit determines that the final end node has been reached, and returns to the standby stage.

[0010] As a preferred technical solution of the present invention, the vibration stage is divided into an effective vibration sub-stage and a compaction sub-stage in chronological order, and the nodes also include compaction nodes; in the vibration stage, when the input electrical signal changes from a decreasing or increasing trend to a stable state, the identification and analysis unit determines and records the current time point as the compaction node, and enters the compaction sub-stage; the identification and analysis unit calculates the pull-out speed of the vibrator rod based on the duration between the vibration start node and the compaction node.

[0011] As a preferred technical solution of the present invention, step S3 specifically includes: when it is determined that the insertion stage, vibration stage and pull-out stage have been entered, the identification and analysis unit sends an instruction to the motor control unit to control the motor to run at the corresponding set vibration frequency; when it is determined that the final end node has been reached, the identification and analysis unit sends an instruction to the motor control unit to control the motor to return to standby state.

[0012] As a preferred technical solution of the present invention, during the standby phase, the identification and analysis unit compares the input electrical signal obtained by the motor monitoring unit with a preset fault judgment threshold, wherein the fault judgment threshold is a preset input current value or voltage value under normal operating conditions of the vibrating rod motor; if the input electrical signal exceeds the fault judgment threshold, the identification and analysis unit triggers an alarm signal.

[0013] As a preferred technical solution of the present invention, the identification and analysis unit pre-stores an optimal vibration duration, which is obtained through multiple vibration experiments. In each vibration experiment, the duration of each stage from the insertion start node to the final end node is recorded. Based on the vibration data acquired by the vibration sensor and the excitation force of the vibrator, the mechanical energy output during vibration is calculated to evaluate the concrete compaction quality. The vibration duration corresponding to the vibration experiment that yielded the best compaction quality is selected as the optimal vibration duration. During the vibration stage, the identification and analysis unit starts timing from the vibration start node. When the timing reaches the optimal vibration duration, the identification and analysis unit issues a prompt signal or a lifting control command. The identification and analysis unit also uploads the vibration process data acquired by the system to the server for monitoring and management of the construction process. The vibration process data includes suspension voltage, input electrical signal, time node records, vibration data, attitude data, vibration frequency, vibration duration, and start-up time. The vibration duration is the time interval from the vibration start node to the withdrawal start node, and the start-up time is the start-up time of the intelligent vibrator system.

[0014] This invention uses a floating voltage detection unit to monitor the vibration depth and contact state in real time, combined with a motor monitoring unit to monitor changes in the motor input electrical signal. This allows for precise and rapid determination of the timing of multiple working stages and key nodes, thereby enabling the tracking and acquisition of key process parameters such as vibration time and depth. Simultaneously, this invention utilizes various sensing elements to acquire vibration frequency, amplitude, and tilt angle data in real time, achieving quantitative control over the quality of vibration. The various functional units collaborate to transform the traditional experience-based vibration operation into a traceable, standardized, and controllable "white-box" process, effectively ensuring the uniformity and reliability of concrete vibration quality.

[0015] Figure 1 This is a schematic diagram of the intelligent vibrating rod system according to one embodiment of the present invention; Figure 2 This is a schematic diagram of the intelligent vibrating rod system according to another embodiment of the present invention; Figure 3 This is a schematic diagram illustrating the changing trend of data obtained by the motor monitoring unit of the present invention during the complete vibration process. Detailed Implementation

[0016] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0017] like Figure 1 As shown, an intelligent vibratory tamping rod system includes a vibratory tamping rod 1, a motor (not shown) disposed inside the head of the vibratory tamping rod 1, and a control module 2 electrically connected to the vibratory tamping rod 1. The control module 2 includes a motor control unit 21, a motor monitoring unit 22, a floating voltage detection unit 23, and an identification and analysis unit 24.

[0018] The motor is a brushless permanent magnet motor or an asynchronous induction three-phase motor, used to drive the vibrating rod 1 to vibrate at a specified vibration frequency.

[0019] The shell of the vibrating rod 1 is a metal conductor, and a detection conductor 3 is also provided at a certain distance above it, such as... Figure 2 As shown, the height difference between the detection conductor and the head of the vibrator 1 is the set depth to which the vibrator needs to be inserted into the concrete. The floating voltage detection unit 23 is connected to the housing of the vibrator 1 through a first wire and to the detection conductor through a second wire; through these two independent lines, the floating voltage detection unit 23 can monitor the floating voltage of the housing of the vibrator 1 and the detection conductor 3 respectively.

[0020] When neither the vibrator 1 nor the detection conductor 3 is in contact with concrete, a certain floating voltage exists between the casing and the detection conductor and ground due to environmental factors. When either the vibrator 1 or the detection conductor 3 comes into contact with concrete, the conductor is grounded, and the impedance of the corresponding path to ground drops sharply, causing the floating voltage to plummet to near zero. The floating voltage detection unit 23 monitors the floating voltage at both the casing of the vibrator 1 and the detection conductor 3 in real time and sends the measured floating voltage to the identification and analysis unit 24. When the floating voltage value of the casing of the vibrator 1 is lower than the first threshold, the identification and analysis unit 24 determines that the vibrator 1 has come into contact with concrete; when the floating voltage value of the detection conductor is lower than the second threshold, the identification and analysis unit 24 determines that the insertion depth of the vibrator 1 has reached the set depth. The first and second thresholds can be determined as values ​​close to zero based on the actual situation.

[0021] The motor monitoring unit 22 is used to monitor the input electrical signals of the motor, including input voltage, input current and / or input power, and sends the obtained data to the identification and analysis unit 24 in real time.

[0022] The identification and analysis unit 24 is a microprocessor with a pre-installed state recognition algorithm. This unit receives signals from the floating voltage detection unit 23 and the motor monitoring unit 22, determines the working state of the vibrator 1 through the state recognition algorithm, and outputs control commands to the motor control unit 21 to realize intelligent control of the vibrator 1.

[0023] like Figure 3 As shown, the operation of the vibratory rod can be divided into four stages in chronological order: standby stage, insertion stage, vibration stage, and withdrawal stage. Figure 3 In the diagram, the standby phase corresponds to the time periods 0~t1 and after t5; the insertion phase corresponds to the time periods t1~t2; the vibration phase corresponds to the time periods t2~t4; and the pull-out phase corresponds to the time periods t4~t5. Insertion start node, vibration start node, pull-out start node, and final end node are defined as the start and end nodes for each phase. Figure 3 The values ​​t1, t2, t4, and t5 correspond to the times shown in the figure. In addition, this embodiment also defines a compaction node, corresponding to time t3 in the figure, and divides the vibration stage into an effective vibration sub-stage and a compaction sub-stage, corresponding to the time periods t2~t3 and t3~t4 in the figure, respectively. When the vibrator head just touches the concrete, the insertion start node is reached, and the system transitions from the non-insertion stage to the insertion stage. In this stage, the vibrator is rapidly inserted vertically downwards into the concrete. When the vibrator reaches the set insertion depth, the vibration start node is reached, and the system transitions from the insertion stage to the vibration stage. In this stage, the motor drives the vibrator to vibrate at a set frequency. During the vibration stage, the motor's input voltage and current gradually decrease from their peak values ​​and tend to stabilize. When the motor's input electrical signal is basically stable, the compaction node is reached, and the system transitions from the effective vibration sub-stage to the compaction sub-stage. When the vibrator finishes vibrating, the withdrawal start node is reached, and the system transitions from the vibration stage to the withdrawal stage. In this stage, the vibrator continues to vibrate while being slowly pulled upwards. When the vibrator is completely removed from the concrete, the vibration ends, and the system reaches the final end node, returning to the standby stage from the withdrawal stage.

[0024] In each of the above stages, the trend curves of the motor's input voltage, input current, and power are as follows: Figure 3During the standby phase, the motor is unloaded, and the input voltage and current remain at a low level. During the insertion phase, the motor load increases rapidly with the insertion depth, and the motor input voltage and current rise rapidly simultaneously. The motor drives the vibrator to vibrate at the set frequency. After reaching the set depth, the vibration phase begins, where the motor load remains relatively stable, and the motor input voltage and current also remain at a relatively high level with a slight downward trend. This downward trend decreases to almost zero as the concrete is compacted, and the motor operating frequency remains unchanged. During the withdrawal phase, the load gradually decreases, and the motor input voltage and current show a downward trend, while the motor operating frequency remains unchanged. This continues until the vibrator is completely withdrawn, returning to the standby phase, where the voltage and current return to near their initial values.

[0025] The intelligent vibration process for concrete vibration using the above-mentioned intelligent vibrator system includes the following steps: During the standby phase, if the floating voltage detection unit 23 detects a floating voltage on the vibrator shell exceeding the detection threshold, and the motor monitoring unit 22 detects that the motor electrical signal remains stable near the no-load value, this indicates that the motor is in a no-load state. The identification and analysis unit 24 integrates both pieces of information and maintains the judgment that the vibrator is in the standby phase. The motor control unit 21 controls the motor to remain in standby mode. In standby mode, the motor does not run or runs at a lower operating frequency.

[0026] During the standby phase, if the floating voltage detection unit 23 detects that the floating voltage of the casing suddenly drops to zero or below a threshold close to zero, the identification and analysis unit 24 immediately determines whether there is an upward trend in the motor input voltage, input current, and power acquired by the motor monitoring unit 22. If there is an upward trend, the identification and analysis unit 24 determines that the insertion phase has been entered, and records the time when the floating voltage drops below the threshold as the insertion start node. The identification and analysis unit 24 can simultaneously send a command to the motor control unit 21 to start the motor or increase the operating frequency, so that the motor drives the vibrator to vibrate the concrete at the preset operating frequency corresponding to the insertion phase.

[0027] Simultaneously, fault detection is performed during this stage: as a fault judgment threshold; each time the standby stage is entered, the identification and analysis unit 24 compares the actual input current or voltage obtained by the motor monitoring unit 22 with the fault judgment threshold, which is the preset input current or voltage value of the vibrator motor under normal working conditions; if the actual current or voltage exceeds the threshold, it is determined that the vibrator is faulty, and an alarm is issued to the operator through an audible and visual alarm to ensure that the vibrator is in normal condition before the next use, and to avoid affecting the concrete vibration quality due to equipment failure.

[0028] During the insertion phase, the motor monitoring unit 22 continuously monitors the changing trend of the motor electrical signal. When the upward trend ends and the motor electrical signal shows a slight decrease near a high value and tends to stabilize, with the decrease being less than a preset threshold, the identification and analysis unit 24 determines that the vibration stage has begun and records the current time point as the vibration start node. The identification and analysis unit 24 can simultaneously send instructions to the motor control unit 21 to increase the motor's operating frequency and drive the vibrator to vibrate the concrete according to the preset operating frequency corresponding to the vibration stage.

[0029] During the vibration stage, the motor monitoring unit 22 continuously monitors the changing trend of the motor electrical signal. When the electrical signal reaches a stable state, the current time point is recorded as the compaction node. The identification and analysis unit 24 can calculate the target lifting speed for the pull-out stage based on the time length from the vibration start node to the compaction node. When the motor electrical signal shows a continuous downward trend and the rate of change is greater than a preset threshold, the identification and analysis unit 24 determines that the pull-out stage has been entered, and simultaneously records the current time point as the pull-out start node. The identification and analysis unit 24 can simultaneously send instructions to the motor control unit 21 to maintain or reduce the motor's operating frequency, driving the vibrator to vibrate the concrete according to the preset operating frequency corresponding to the pull-out stage.

[0030] During the unplugging phase, the motor monitoring unit 22 continuously monitors the changing trend of the motor electrical signal. If the floating voltage detection unit 23 detects that the housing floating voltage has returned to a non-zero value, and the motor monitoring unit 22 detects that the downward trend of the motor electrical signal has ended and the electrical signal is stable near the no-load value, then the identification and analysis unit 24 determines that the standby phase has been restored, and records the time point when the floating voltage returns to a non-zero value as the final termination point. The identification and analysis unit 24 can simultaneously send a command to the motor control unit 21 to restore the motor to standby mode.

[0031] When the motor monitoring unit 22 or the floating voltage detection unit 23 detects a fault, the following descent control logic is adopted: When the data acquired by the motor monitoring unit 22 is abnormal or lost, the system automatically switches to a mode that relies solely on the floating voltage detection unit 23. In this mode, the insertion start node, vibration start node, and final end node can still be accurately determined. When the data acquired by the floating voltage detection unit 23 is abnormal or lost, the system automatically switches to a mode that relies solely on the motor monitoring unit. In this mode, the motor monitoring unit 22 continuously monitors the motor input electrical signal and determines each node solely based on the motor input electrical signal. The accuracy of determining the vibration start node and final end node is slightly reduced.

[0032] Furthermore, the intelligent vibratory tamping rod is also equipped with a vibration sensor and an attitude sensor. The vibration sensor is used to detect vibration data such as vibration frequency and amplitude during operation, and the attitude sensor is used to detect attitude data such as axial tilt angle and acceleration of the vibratory tamping rod. The intelligent vibration tamping process also includes an experimental and application process for determining the optimal vibration time, specifically including the following steps: During the experimental calibration phase, multiple vibration operations were performed using the intelligent vibrator system for concrete with a specific mix proportion. During each vibration operation, the identification and analysis unit 24 recorded the time interval between the vibration start point and the withdrawal start point, denoted as the vibration duration. Simultaneously with each operation, the identification and analysis unit 24, based on vibration sensor data or the vibrator's excitation force, calculated the cumulative mechanical energy input into the concrete during the insertion, vibration, and withdrawal stages, using this as an evaluation index for assessing the concrete's vibration quality. The vibration duration recorded during the operation with the highest score was selected as the optimal vibration duration for that concrete mix proportion.

[0033] During the actual construction phase, for concrete with a pre-calibrated mix proportion, the optimal vibration time is preset in the identification and analysis unit 24. When the vibrator enters the vibration stage, the identification and analysis unit 24 automatically starts timing from the recorded vibration start point. This timing information can be transmitted to the operator via wired or wireless means and is visible to the operator. When the timing value reaches the preset optimal vibration time, the identification and analysis unit 24 can issue a prompt signal or a lifting control signal according to the system settings. The prompt signal refers to the identification and analysis unit 24 issuing a prompt signal to the operator through a built-in audible and visual alarm, prompting the operator to start lifting the vibrator. The lifting control signal refers to, in systems equipped with external lifting devices such as robotic arms or automatic lifting frames, the identification and analysis unit 24 sending a signal to the control system of the lifting device, causing the device to lift the vibrator at a preset speed until the final end point is reached. Alternatively, during the compaction process with one or more vibrators, if workers judge the compaction time based on visible information such as slurry rising, bubbling, and collapse, the system can collect, statistically analyze, and track the duration of each stage in real time. All data from this system is transmitted wirelessly to the server for monitoring and management of the on-site vibration process and results, thereby achieving the purpose of on-site vibration construction management and monitoring.

[0034] By combining the axial tilt angle and acceleration of the vibrator measured by the attitude sensor, the insertion depth of the vibrator can be calculated in real time to determine whether the set depth has been reached. This calculated real-time depth value can be cross-checked with the fixed depth value set by the suspension voltage detection unit 23.

[0035] The aforementioned intelligent vibratory tamping system and intelligent vibration process can accurately determine the working status of the vibratory tamping rod based on multi-source data, and further obtain vibration time, vibration depth, and vibration quality based on the status judgment. It controls the start and stop of the vibratory tamping rod and intelligently changes the vibration frequency. Furthermore, it can guide or automatically execute the rod lifting operation when the optimal vibration time is reached. The entire system not only achieves white-box monitoring and intelligent control of the entire vibration process, ensuring stable and optimal vibration quality, but also significantly improves the system's reliability.
