Description

Technical Field

[0001] The present invention relates to the field of equipment control, and in particular to a monitoring method and a monitoring system for a construction environment of a building project. Background Art

[0002] In modern construction projects, concrete is one of the most basic building materials, and its quality is directly related to the safety and durability of the structure. The strength of concrete is a key indicator to measure its quality. The strength of concrete is not only affected by the ratio of its raw materials (such as water-cement ratio, aggregate type, additives, etc.), but also closely related to the vibration process during the pouring process. Vibration is to make the concrete mixture fully dense in the formwork through mechanical vibration, remove excess water and bubbles, so as to achieve the purpose of improving the uniformity and strength of concrete. However, traditional vibration operations rely on the experience of operators, lack scientific parameter guidance and real-time feedback mechanisms, often resulting in insufficient or excessive vibration, affecting the consistency of concrete quality, and even causing engineering quality risks.

[0003] With the development of the Internet of Things, big data and artificial intelligence technologies, new possibilities have been provided for the monitoring and management of the construction environment of building projects. By integrating sensors, cloud computing and data analysis technologies, accurate monitoring and intelligent regulation of the construction process can be achieved, thereby effectively improving construction quality and efficiency. At present, there are some solutions for concrete construction monitoring on the market, but most of these solutions focus on concrete composition detection or simple construction records, and there is still a lack of effective means for the dynamic adjustment and optimization of vibration parameters. Summary of the invention

[0016] Furthermore, the vibration deviation of the vibration equipment is obtained according to the current relationship between the vibration parameters of the vibration equipment and the concrete density and the initial relationship between the vibration parameters of the vibration equipment and the concrete density, including:

[0017] A vibration deviation of the vibrating device is obtained according to a difference between the concrete density in a current relationship between the vibration parameters of the vibrating device and the concrete density and the concrete density in an initial relationship between the vibration parameters of the vibrating device and the concrete density.

[0040] Step six: Complete construction monitoring of the construction environment.

[0041] The concrete test blocks cast according to the concrete parameters and the corresponding vibration parameters are subjected to pressure tests to obtain the actual strength of the concrete test blocks, and the strength achievement rate of the concrete test blocks is obtained according to the difference between the actual strength of the concrete test blocks and the expected strength, including:

[0042] Different concrete parameters correspond to different vibration parameters. Concrete test blocks are cast according to the concrete parameters and the corresponding vibration parameters, and pressure tests are performed to obtain the actual strength of the concrete test blocks, wherein the vibration parameters include vibration time and vibration power. According to the difference between the actual strength of the concrete test block and the expected strength corresponding to the concrete parameters, the strength achievement rate of the concrete test block is obtained, using the following formula:

[0043] .

[0044] The obtaining of concrete parameters and vibration parameters of a concrete test block whose strength achievement rate is less than a strength achievement rate threshold, as well as density data of the concrete test block, and obtaining the current relationship between the vibration parameters of the vibration equipment and the density of the concrete, includes:

[0045] The concrete parameters and vibration parameters of the concrete test blocks whose strength achievement rate is less than the strength achievement rate threshold are obtained, and the density of the concrete test blocks whose strength achievement rate is less than the strength achievement rate threshold is collected to obtain the current relationship between the vibration parameters of the vibration equipment and the concrete density.

[0046] The vibration deviation of the vibration equipment is obtained according to the current relationship between the vibration parameters of the vibration equipment and the concrete density and the initial relationship between the vibration parameters of the vibration equipment and the concrete density, including:

[0047] A vibration deviation of the vibrating device is obtained according to a difference between the concrete density in a current relationship between the vibration parameters of the vibrating device and the concrete density and the concrete density in an initial relationship between the vibration parameters of the vibrating device and the concrete density.

[0048] The initial relationship between the vibration parameters of the vibrating equipment and the density of concrete and the vibration deviation of the vibrating equipment are sent to the deviation compensation module, and the deviation compensation module obtains the compensated vibration parameters according to the vibration deviation of the vibrating equipment, including:

[0049] The deviation compensation module obtains the compensated vibration power according to the difference in concrete density and the sum of the concrete density in the initial relationship between the vibration parameter and the concrete density, replaces the vibration power in the vibration parameter with the compensated vibration power, and binds it to the concrete parameter.

[0050] The cloud data server stores a data table corresponding to the concrete density and vibration power of the corresponding concrete parameters.

[0051] like Figure 2 As shown, a monitoring system for a construction environment of a building project, using the monitoring method for a construction environment of a building project, includes a cloud data server, a vibrating equipment control module, a communication device, a data processing module, a data storage module, a deviation compensation module, and a concrete test block data acquisition module;

The method establishes a construction monitoring management container through a cloud data server, integrates functions such as concrete parameter acquisition, vibration parameter optimization, real-time monitoring and feedback adjustment, realizes refined management of the concrete pouring process, and ensures the stability and consistency of concrete strength.

[0055] The technical solution of the present invention comprises the following steps:

[0056] Step 1: Cloud data initialization and expected intensity calculation

[0057] The cloud data server establishes a construction monitoring management container to store and process various data during the construction process.

[0058] Obtain concrete parameters at each construction stage, including but not limited to cement dosage, water-cement ratio, aggregate type and proportion, additive type and dosage, etc.

[0059] Based on the concrete parameters, the expected strength of the concrete is calculated using a preset algorithm or database.

[0060] Step 2: Concrete specimen pressure test and strength achievement rate assessment

[0061] Cast concrete test blocks according to different concrete parameters and corresponding vibration parameters (such as vibration duration and vibration power). Perform pressure tests on concrete test blocks to obtain their actual strength. Calculate the difference between the actual strength of the concrete test block and the expected strength, and then obtain the strength achievement rate.

[0062] The formula for calculating the strength achievement rate is: Strength achievement rate = 1 - (actual strength - expected strength) / expected strength.

[0063] If the strength achievement rates of all concrete test blocks exceed the preset strength achievement rate threshold (such as 95%), proceed to step 6; otherwise, proceed to step 3.

[0064] Step 3: Analysis of the relationship between vibration parameters and density

[0065] For concrete test blocks that do not meet the strength achievement rate, obtain their concrete parameters, vibration parameters, and density data. Analyze the current relationship between vibration parameters (vibration time, vibration power) and concrete density. Compare with the initial relationship between the vibration parameters of the vibration equipment and the concrete density (based on historical data or experimental acquisition), and calculate the vibration deviation of the vibration equipment.

[0066] Step 4: Vibration parameter compensation and optimization

[0067] The initial relationship between the vibration parameters of the vibration equipment and the concrete density and the vibration deviation are sent to the deviation compensation module. The deviation compensation module calculates the compensated vibration parameters, especially the adjustment value of the vibration power, based on the vibration deviation. The compensated vibration parameters are sent to the vibration equipment control module and bound to the specific concrete parameters to achieve a personalized vibration solution.

[0068] Step 5: Iterative optimization and verification

[0069] Obtain the concrete parameters and vibration parameters of the next concrete test block whose strength achievement rate does not meet the standard, and repeat steps 3 to 4 until all concrete test blocks whose strength achievement rates do not meet the standard are compensated by the vibration parameters. Continuously iterate and optimize to ensure that the strength achievement rates of all concrete test blocks meet the requirements.

[0070] Step 6: Construction monitoring completed

[0071] Complete comprehensive construction monitoring of the construction environment and generate monitoring reports, including concrete strength distribution, vibration parameter optimization effects, etc.

[0072] Concrete block pressure test and strength achievement rate assessment: Use automated pressure test equipment to ensure the accuracy and consistency of test results. Strength achievement rate thresholds can be flexibly set according to project requirements and industry standards.

[0073] Analysis of the relationship between vibration parameters and density: Use built-in sensors or external detection equipment to monitor the density of concrete test blocks in real time. Use machine learning algorithms to analyze the nonlinear relationship between vibration parameters and density to improve prediction accuracy.

[0074] Vibration parameter compensation and optimization: The deviation compensation module dynamically adjusts the vibration parameters based on historical data and real-time feedback. The compensation strategy may include increasing or decreasing the vibration power, adjusting the vibration duration, etc., which is determined according to the actual situation.

[0075] System architecture and data interaction: The system includes cloud data server, vibration equipment control module, communication device, data processing module, data storage module, deviation compensation module, concrete test block data acquisition module, etc. The modules can realize real-time data transmission and sharing through high-speed communication network to ensure the timeliness of monitoring and control.

[0076] Example 1: In a construction project of an urban underground comprehensive pipeline corridor, due to the narrow and complex construction environment, the quality requirements for concrete are extremely high. Traditional vibration operations often result in uneven concrete density and difficulty in ensuring strength due to space limitations and uncertainties in manual operations. After adopting the monitoring system of the present invention, a detailed construction monitoring and management container is first established through a cloud data server, covering all concrete parameters and construction conditions. During the actual pouring process, the system monitors the density and strength achievement rate of the concrete test blocks in real time. Once an abnormality is found, the vibration parameter optimization program is immediately started. Through several rounds of iterative adjustments, the system successfully found the most suitable vibration parameters for the construction environment, ensuring that the strength of each cubic meter of concrete meets the design requirements. In addition, the system also discovered potential problems in construction through data analysis, such as fluctuations in raw material quality and wear of vibration equipment, effectively avoiding the occurrence of quality accidents.

[0077] Embodiment 2:

[0078] In a dam pouring project of a large-scale water conservancy project, due to the huge size of the dam, the amount of concrete poured is huge, and it needs to withstand extremely high water pressure, so the quality and strength requirements of the concrete are extremely strict. The traditional vibration operation method is difficult to adapt to such large-scale and high-quality construction requirements. For this reason, the project party introduced the monitoring system of the present invention.

[0079] At the beginning of the project, the system first conducted a comprehensive parameter analysis and expected strength calculation of the concrete required for the dam construction. Subsequently, during the concrete pouring process, the system monitored the density and strength of the concrete test blocks in real time, and dynamically adjusted the vibration parameters according to changes in the construction environment (such as temperature, humidity, wind speed, etc.). Through the intelligent control of the system, the vibration equipment can always maintain the best working state, ensuring that the density and strength of the concrete reach the expected goals.
