Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a lightweight wall spraying process based on artificial intelligence. Background Art

[0002] Lightweight wall spraying technology is an important technology in modern building construction and is widely used in wall decoration and protection. However, the traditional lightweight wall spraying technology mainly relies on manual experience and preset parameters, and it is difficult to optimize and dynamically adjust in real time according to actual conditions during the construction process. The limitations of this process method lead to problems such as unstable spraying quality, material waste and low efficiency, which restricts the overall quality and efficiency of building construction.

[0003] In the prior art, the parameters of the spraying process are usually set based on experimental data before construction and the experience of operators. These parameters may need to be adjusted during the actual construction process due to environmental conditions, equipment status, and changes in wall materials. However, manual adjustment of parameters is not only time-consuming and laborious, but also difficult to ensure consistency and accuracy of the adjustment effect. Especially in large-area spraying or complex structure wall construction, the limitations of manual adjustment are more obvious, and it is difficult to maintain stable spraying quality.

[0004] The traditional spraying process also has the problem of being highly dependent on manual operation. The operation of spraying equipment is usually completed by skilled workers. The workers' operating skills and experience directly affect the spraying quality. However, the operating levels of different workers vary. Even the operations of the same worker at different times may be different, resulting in inconsistent spraying quality. In addition, manual operation is difficult to maintain high efficiency in a complex and changeable construction environment, resulting in low spraying efficiency and high labor costs.

[0005] In addition, the traditional spraying process lacks the ability to monitor and analyze data in real time during the spraying process. During the construction process, it is impossible to obtain and analyze key parameters such as spraying thickness, uniformity, material consumption, spraying pressure, and ambient temperature and humidity in real time, and it is impossible to adjust the operating parameters of the spraying equipment in time. Due to the lack of real-time data support, the spraying quality is difficult to guarantee, material waste is serious, and construction efficiency is low.

[0006] In response to the above problems, there have been some attempts in the prior art to use automated equipment and basic control systems to improve the spraying process. However, these systems can often only achieve simple execution of preset parameters and lack the ability of intelligent optimization and dynamic adjustment. Although the automated system has improved the spraying efficiency to a certain extent, due to the inability to analyze and adjust parameters in real time, its spraying quality and consistency are still difficult to reach the ideal level.

[0007] In addition, most of the spray process optimization methods in the existing technology are based on traditional optimization algorithms, which are inefficient when dealing with complex and multi-variable spray parameters and difficult to achieve real-time optimization. For example, simple rule-based optimization methods cannot cope with the dynamic changes in the spray process, and the optimization effect is not ideal. Although some studies have tried to use machine learning and intelligent algorithms to optimize the spray process, these methods are usually limited to offline data analysis, lack real-time application capabilities, and fail to make full use of real-time data for dynamic optimization.

[0008] In short, the traditional lightweight wall spraying process has obvious defects in real-time optimization, dynamic adjustment, degree of automation and consistency, which seriously restricts the improvement of spraying quality and construction efficiency; for this reason, the applicant proposes an optimization method for lightweight wall spraying process based on artificial intelligence according to the spraying needs. Through intelligent optimization algorithms, real-time data analysis and feedback, integrated automation systems and other means, real-time optimization and dynamic adjustment of the spraying process are achieved, the spraying quality and efficiency are improved, material waste and labor costs are reduced, and it is possible to adapt to complex and changeable construction environments.

The preprocessed data is analyzed using an adaptive distributed generative adversarial network algorithm to construct a prediction model for the spraying process. The prediction model can predict the spraying effect in real time according to the input parameters, generate feedback signals, and adjust the operating parameters of the spraying equipment through an intelligent optimization algorithm; a closed-loop control is formed, so that the spraying quality is continuously optimized during the construction process, material waste is reduced, and construction efficiency is improved.
