Therefore, the present invention is not limited to the specific embodiments disclosed below.

The plurality of vibrating rods 3 are adjusted in the horizontal direction by an adjustment mechanism 4, and each vibrating rod 3 is provided with a six-axis inertial measurement unit (not shown in the figure); the data processing unit is used to receive data from the intelligent online monitoring device and the six-axis inertial measurement unit and perform analysis and processing; the control unit is in communication with the data processing unit and the vibrating device, and dynamically adjusts the vibration parameters of the vibrating device according to the analysis results of the data processing unit; the user interface is in communication with the control unit and the data processing unit, and is used to display real-time monitoring data, vibration status, and receive user input instructions.

[0039] The intelligent online monitoring equipment includes: an ambient temperature sensor for real-time monitoring of the ambient temperature in the pouring and vibration area; a camera for real-time monitoring of the vibration status, capturing images or videos of the vibration status in real time and transmitting the collected information to the data processing unit; and a concrete type identification module, which uses an RFID reader to read the concrete's RFID tag to obtain the concrete's strength grade, slump, aggregate particle size, and water-cement ratio. The ambient temperature sensor, camera, and RFID reader communicate with the data processing unit via wired or wireless means to transmit measured data, images or videos, and concrete information to the data processing unit.

[0040] The bottom of the mobile frame 1 is provided with a driving wheel 11 and a driven wheel 12 for rotation. The driving wheel 11 is fixedly connected to the output shaft of a traveling motor 13 fixedly set on the mobile frame 1, and the traveling motor 13 is electrically connected to the control unit. The mobile frame 1 is provided with two lifting cylinders 14. The piston rods of the two lifting cylinders 14 are set vertically downward, and the bottoms of the piston rods are fixedly connected to the middle of the vertical slide 2. A plurality of vibrating rods 3 are provided on the vertical slide 2. Each vibrating rod is respectively connected to the corresponding vibration motor 32 through a hose 31. The vibration motor 32 is fixedly set on the top of the mobile frame 1. The vibration motor 32 is set corresponding to the vibrating rod 3. The number of the vibration motors 32 is the same as the number of the vibrating rods 3. The vibration motor 32 provides power for the vibrating rod 3. Each vibration motor 32 is electrically connected to a control unit, which can control the start and stop of each vibration motor 32 separately. Multiple vibration motors 32 can operate synchronously or asynchronously, that is, all or some of the vibration motors 32 can be turned on or off according to the vibration requirements, thereby achieving synchronous or asynchronous vibration of multiple vibrating rods 3. Each vibrating rod 3 is equipped with a six-axis inertial measurement unit, which is embedded in the vibrating rod 3 and is used to monitor the vibration frequency, vibration time, and insertion depth of the vibrating rod 3, and transmit this monitoring data to the data processing unit. Several cameras and laser displacement sensors are installed at the bottom of the vertical slide 2. The camera shooting angle is set towards the vibrating rod 3 to capture images and videos of bubbles and vibration ripples on the concrete surface during the vibration process. The laser displacement sensor is used to monitor the settlement of the concrete surface. Start the traveling motor 13, the output shaft of the traveling motor 13 rotates to drive the driving wheel 11 to rotate, and the driving wheel 11 rotates to drive the mobile frame 1 to move, so that the mobile frame 1 drives the vibrating rod 3 to move along the length direction of the pre-cast and vibrated concrete to perform large-area construction vibration operations.

[0041] The horizontal spacing of multiple vibrating rods 3 is adjusted by an adjustment mechanism 4, thereby adjusting the vibration spacing between the vibrating rods 3 to meet the vibration requirements of concrete components of different widths. The adjustment mechanism 4 includes a horizontal slide rail 41 provided on the vertical slide 2, and multiple sliders 42 are slidably connected to the horizontal slide rail 41. The sliders 42 are connected by a connecting rod assembly 43. A push-pull cylinder 44 is horizontally provided on the vertical slide 2, and the movable end of the push-pull cylinder 44 is fixedly connected to the slider 42 located at the end. Specifically, the connecting rod assembly 43 includes four first connecting rods 431, each two first connecting rods 431 form a group, and the two first connecting rods 431 in each group are hinged in a V shape. One end of the two first connecting rods 431 is hinged to the upper part of the slider 42 located at both ends through a rotating shaft. Each slider 42 in the middle is connected by a second connecting rod 432. The two second connecting rods 432 are arranged in an X-shaped structure, and the middle portions of the two second connecting rods 432 are hinged to the upper portion of the middle slider 42. The two ends of the two second connecting rods 432 are respectively hinged to the second connecting rod 432 or one end of the first connecting rod 431 on the left and right sides of the middle slider 42. A push-pull cylinder 44 is located at one end of the slider 42, and its piston rod is fixedly connected to the side wall of the slider 42 at the corresponding end. A clamping plate 45 is provided on the side wall of each slider 42, and the clamping plate 45 is fixedly engaged with the outer shell of the vibrating rod 3. Specifically, the clamping plate 45 is provided with a through hole for the vibrating rod 3 to pass through. The through hole has a slot along its axial direction near its upper and lower ends. Both slots are equipped with a hole elastic circlip (not shown in the figure). The two hole elastic circlips limit the axial position of the vibrating rod 3 to ensure its fastening to the clamping plate 45.

[0042] The push-pull cylinder 44 extends and retracts, driving the end slider 42 to move along the length of the horizontal slide rail 41. Since the sliders 42 are connected by the connecting rod assembly 43, they are driven to slide along the length of the horizontal slide rail 41, thereby adjusting the vibration spacing of the vibrating rods 3 fixed to the sliders 42. For example, when the concrete component to be produced is relatively wide, the push-pull cylinder 44 is extended to drive the end slider 42 to slide. Under the action of the connecting rod assembly 43, the end slider 42 drives the sliders 42 to move away from each other, increasing the spacing between the sliders 42 and thus increasing the vibration spacing between the vibrating rods 3. Conversely, when the concrete component to be produced is relatively narrow, the push-pull cylinder 44 is retracted to drive the end slider 42 to slide in the opposite direction. Under the action of the connecting rod assembly 43, the end slider 42 drives the sliders 42 to move toward each other, decreasing the spacing between the sliders 42 and thus decreasing the vibration spacing between the vibrating rods 3, thereby adapting to the vibration requirements of concrete components of different widths.

[0043] The present invention also provides a monitoring method of a concrete quality monitoring system, comprising the following steps:

[0044] S1. When concrete is poured into the mold, the concrete type identification module obtains concrete parameters, while the ambient temperature sensor monitors the temperature of the pouring and vibrating area in real time. Specifically, the RFID reader reads the concrete's RFID tag to obtain the concrete's strength grade, slump, aggregate particle size, and water-cement ratio. The ambient temperature sensor is used to monitor the ambient temperature of the pouring area in real time.

[0045] S2: The acquired concrete parameters, temperature data and width of the concrete component are input into the dynamic parameter adjustment model of the data processing unit to calculate the initial vibration parameters. The calculated initial vibration parameters include vibration spacing, vibration time and vibration frequency. The strength grade, slump, aggregate particle size and water-cement ratio of the concrete, and the ambient temperature of the pouring area are transmitted to the data processing unit via wired or wireless transmission. At the same time, the width of the pre-cast and vibrated concrete component is input into the data processing unit, and the staff calculates the vibration spacing and insertion depth of the vibrating rod based on the width and height of the concrete component. The data processing unit transfers the collected concrete parameters and temperature data into the dynamic parameter adjustment model to calculate the optimal vibration time and vibration frequency for the vibration operation.

[0046] The working process of the dynamic parameter adjustment model is as follows:

[0047] S21. Receive data from the ambient temperature sensor and the concrete type identification module, mainly including ambient temperature, concrete strength grade, slump, aggregate particle size and water-cement ratio.

[0048] S22. Based on the slump, the temperature effect of the Arrhenius equation and the water-cement ratio, the vibration time is corrected and adjusted; the vibration frequency output is dynamically adjusted based on the aggregate particle size, temperature and strength grade.

[0049] In step S22, the calculation formula for the vibration time is: Among them, t is the calculated vibration time, t0 is the reference time, K W / C is the water-cement ratio correction coefficient, the value range of Ea is 35~40KJ / mol, and R is the gas constant 8.314J / (mol·K).

[0050] The calculation formula for t0 is:

[0051] Sl is the slump of concrete.

[0052] K W / C The calculation formula is:

[0053] W / C is the water-cement ratio.

[0054] The calculation formula of vibration frequency is: f=f0×K temp ×K strength , where f is the calculated vibration frequency, f0 is the reference frequency, and K temp is the temperature correction coefficient, K strength is the strength correction factor.

[0055] Specifically, the calculation formula for f0 is:

[0056] D is the maximum particle size of aggregate;

[0057] K temp The calculation formula is:

[0058] T is the ambient temperature

[0059] K strength The calculation formula is:

[0060] S is the strength grade.

[0061] The above formula shows that by inputting the slump of concrete, ambient temperature and water-cement ratio of concrete, the required concrete vibration time can be calculated. For example, if Sl is 100mm, W / C=0.4 and T=5℃, then

[0062] By inputting the aggregate particle size, ambient temperature and strength grade, the required concrete vibration frequency can be calculated. For example: for C40 concrete, aggregate particle size D = 25mm, ambient temperature T = 40℃, f0 = 100 + 5 × (20-25) = 75Hz, f = 75 × 1.1 × 1 = 82.5Hz.

[0063] Therefore, based on the input of different concrete characteristic parameters and ambient temperature, the data processing unit can automatically calculate the corresponding vibration frequency and vibration time. The vibration frequency, vibration time, vibrator insertion depth and vibration spacing of the vibration operation are transmitted to the control unit via wired or wireless transmission.

[0064] S3: The control unit receives the above data and issues operation instructions, controlling the push-pull cylinder to extend and retract to move each vibrating rod and adjust the distance between adjacent vibrating rods to a predetermined spacing. The lifting cylinder extends and retracts to drive the vertical slide and vibrating rod to a predetermined height. The vibration motor on the vibrating equipment is started, and the vibration motor drives the vibrating rod to vibrate through a hose. The six-axis inertial measurement unit collects the vibration time, insertion depth, and vibration frequency of the vibrating rod in real time during the vibration process, and sends the real-time data of the vibration time and vibration frequency to the data processing unit. During the vibration operation of the vibrating rod, the camera monitors the bubbles and vibration ripples on the concrete surface in real time, and transmits the captured images or videos to the data processing unit via wired or wireless means. The bubbles and vibration ripples on the concrete surface are displayed on the user interface, allowing workers to observe the vibration status of the concrete in real time. The laser displacement sensor transmits the monitored concrete surface settlement to the data processing unit, and displays the concrete surface settlement on the user interface.

[0065] S4: The data processing unit analyzes the collected data, including the vibrating time, insertion depth, and vibration frequency of the vibrating rod captured in real time by the six-axis inertial measurement unit, as well as images or videos of bubbles and vibration ripples on the concrete surface captured by the camera, and the concrete surface settlement captured by the laser displacement sensor. The data processing unit compares the actual vibration time, insertion depth, and vibration frequency monitored in real time with the relevant data of the initial parameters calculated in step S2. If the actual measured data is less than the calculated data, the data processing unit preliminarily determines that the area is under-vibrated or missed. If the actual measured data is greater than the calculated data, the data processing unit preliminarily determines that the area is over-vibrated. The data processing unit automatically marks these areas as under-vibrated or over-vibrated, and these abnormality marks are displayed on the user interface display. Based on these under-vibration and over-vibration marks, combined with the bubbles and vibration ripples captured by the camera and the concrete surface settlement measured by the laser displacement sensor, the staff comprehensively determines whether the marked area is under-vibrated or over-vibrated. After comprehensive evaluation, if the marked under-vibration or over-vibration area meets the concrete vibration requirements, the staff manually deletes these abnormality marks. If the abnormal area is determined to be under-vibrated, missed, or over-vibrated, the control unit automatically adjusts the vibration parameters of the vibrating equipment and controls the vibrating rod to move to the under-vibrated or missed area for re-vibration. For over-vibrated areas, the vibration parameters are readjusted to optimize subsequent vibration operations and improve vibration quality.

[0066] S5: During the vibration operation of the vibrating rod, the staff can display the real-time vibration status and monitoring data through the display screen of the user interaction interface. The construction staff can manually adjust the vibration parameters or perform other operations as needed to improve the construction quality of the vibration operation.

[0067] Although the present invention discloses preferred specific embodiments to achieve the above-mentioned objectives, it is not intended to limit the structural features of the present invention. Any person skilled in the art should know that under the technical spirit of the present invention, any easily conceivable changes or modifications are possible and are all covered by the scope of the patent application of the present invention.
