Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a construction noise evaluation method and system, which are used to solve the problem of inaccurate noise evaluation caused by single data and ignoring the user's subjective experience of the construction environment in the existing construction noise evaluation method or system.

[0020] S24, normalizing the noise data of the construction area and the noise data of the key focus area respectively to obtain normalized noise data of the construction area and the key focus area.

[0021] S25. Based on the normalized noise data of the construction area and the key focus area, calculate the first comprehensive noise impact index under the construction environment, namely:

The noise intensity of the construction area grid, Indicates the total number of noise intensity sensors installed in the focus area, Indicates the number of installed noise intensity sensors. The noise intensity of the grid in the focus area, Indicates a rounding operation.

[0023] In this embodiment, the average value of the noise data collected by all noise intensity sensors arranged in the construction area and the key focus area is calculated and used as a comprehensive index to measure the impact of construction environment noise. That is, when the comprehensive noise impact index (first comprehensive noise impact index) of the construction area and the key focus area is large, it can be judged that the noise pollution is serious. In addition, the noise contribution of the construction area and the key focus area can be calculated respectively according to the calculated first comprehensive noise impact index to evaluate the impact of noise, wherein the noise contribution of the construction area and the key focus area is respectively: , represents the noise contribution of the construction area, Indicates the noise contribution of the key focus area; Higher, When it is low, it means that the construction area is the main noise source, indicating that the noise in the construction area will affect the construction workers, so the noise impact can be reduced by adjusting the construction machinery or equipment; Higher, When it is low, it means that the area surrounding the construction site is greatly affected by noise and the noise does not come from the construction environment.

[0024] S3. When construction is underway in a building construction area, the psychological states of construction workers and users in key areas are investigated and counted, and an experience scoring model for construction workers and users on the construction environment is established to calculate the comprehensive experience scoring index in the construction environment.

[0025] Specifically, step S3 specifically includes S31-S34: S31. When construction is being carried out in a construction area, a psychological state survey and statistics are conducted on the construction workers in the construction area, including stress perception, concentration, emotional state, and mental health, to obtain the psychological state results of the construction workers.

[0036] In this embodiment, , Both are 0.5, which means that the experience scores of construction workers and users on the construction environment are equally important.

[0037] S4. When construction is being carried out in a construction area, collect construction phase information data of the construction area, and perform one-hot encoding on the construction phase information data.

In addition, the purpose of selecting the construction phase information data including the construction phase, construction time, and construction machinery information is to capture the noise changes in different stages, different time periods, and different machinery combinations during the construction process, so as to more comprehensively evaluate the impact of the construction phase information on the noise.

[0039] Specifically, step S4 specifically includes S41-S46: S41. When construction is being carried out in a construction area, construction phase information data of the construction area including construction phase, construction time, and construction machinery information is collected.

[0047] S5. After normalizing the first comprehensive noise impact index, the comprehensive experience score index and the second comprehensive noise impact index, the comprehensive weighting method of game theory is used to allocate weights. By establishing a noise evaluation model under the construction environment, the noise score under the construction environment is obtained to evaluate the noise impact of the construction environment.

[0048] Specifically, step S5 specifically includes S51-S56: S51. Normalize the first comprehensive noise impact index, the comprehensive experience scoring index, and the second comprehensive noise impact index respectively to obtain a normalized first comprehensive noise impact index, a comprehensive experience scoring index, and a second comprehensive noise impact index.

[0049] S52. Based on the normalized first comprehensive noise impact index, the comprehensive experience scoring index and the second comprehensive noise impact index, the subjective weights of the normalized first comprehensive noise impact index, the comprehensive experience scoring index and the second comprehensive noise impact index are calculated using the hierarchical analysis method.

[0050] S53. Based on the normalized first comprehensive noise impact index, the comprehensive experience scoring index and the second comprehensive noise impact index, the entropy weight method is used to calculate the objective weights of the normalized first comprehensive noise impact index, the comprehensive experience scoring index and the second comprehensive noise impact index.

[0051] S54. Based on the normalized first comprehensive noise impact index, the comprehensive experience rating index, and the subjective weight and objective weight of the second comprehensive noise impact index, a game model based on the subjective weight and the objective weight is established and solved to obtain the optimal weight combination, namely:

Specifically: like , then the impact of construction noise is minimal and the construction environment is ideal; like , then the impact of construction noise is small and the construction environment is better; like , then the impact of construction noise is moderate, and the construction environment noise should be monitored at all times; like , then the construction noise has a greater impact and noise management is needed; like , then the impact of construction noise is serious and noise management should be carried out immediately.

[0057] like Figure 2 As shown, a noise evaluation system for building construction using the noise evaluation method for building construction comprises: The multi-source data acquisition module is used to collect noise data of construction areas and key areas of concern, psychological state data of construction workers and users in key areas of concern, and construction phase information data of construction areas.

[0058] In this embodiment, by integrating multiple data sources, the noise data, psychological state data, and construction stage information data of the construction area and the key focus area are comprehensively collected, so as to facilitate data preprocessing in the subsequent steps and provide high-quality input data for the noise evaluation model. Among them, the key focus area is the area around the construction area, including residents, schools, and hospitals; secondly, when collecting psychological state data, it is necessary to collect not only the psychological state data of users in the key focus area, but also the psychological state data of construction workers, because excessive noise will not only affect the life and psychological state of surrounding users, but also the physical and psychological state of on-site construction workers.

[0059] The data analysis and processing module is used to analyze and process the noise data of the construction area and the key focus area, the psychological state data of the construction workers and users in the key focus area, and the construction stage information data of the construction area, and to establish a noise evaluation model under the construction environment.

[0061] The early warning module is used to obtain the noise score in the construction environment according to the noise evaluation model in the construction environment, so as to evaluate the noise impact of the construction environment and determine whether to take noise reduction measures for noise management.

[0062] Specifically, the specific process of determining whether to take noise reduction measures to conduct noise management is as follows: if the impact of construction noise is large, the construction time and construction machinery will be adjusted, that is, the construction time will be adjusted to a non-sensitive period, low-noise equipment will be selected, or construction machinery will be regularly maintained; if the impact of construction noise is serious, the construction time and construction machinery will be adjusted, and sound insulation and shielding devices will be set up in the construction area.

[0063] In this embodiment, when the noise score in the construction environment is obtained, the noise impact level in the construction environment can be divided, so as to determine whether to manage the noise of the construction environment according to the impact level; wherein, the means of noise management include adjusting the construction time and construction machinery, and setting up sound insulation and shielding devices in the construction area; adjusting the construction time can be to avoid high-noise operations during sensitive periods (such as nighttime and holidays), or to arrange high-noise operations during the day or non-sensitive periods; adjusting the construction machinery can be to select low-noise equipment (such as low-noise excavators, low-noise concrete mixers, etc.), or regularly maintain the construction machinery to ensure that it is in good operating condition and reduce noise generation; setting up sound insulation and shielding devices in the construction area, that is, setting up sound insulation barriers at the construction site to reduce noise propagation, or setting up sound insulation walls or sound insulation panels around the construction area.

[0064] In summary, the noise evaluation method and system for building construction proposed in the present invention firstly collects multi-source data such as noise data, psychological state data, construction stage information data, and performs data analysis and processing to generate noise impact indicators focusing on the construction area and the surrounding areas of the construction area, experience rating indicators of users and construction workers in the construction environment, and noise impact indicators of the construction stage on the construction environment. These indicators accurately reflect the degree of noise impact in different areas under the construction environment, and at the same time supplement the noise evaluation dimension from the perspective of construction and users, and reveal the relationship between different construction stages and noise impact; secondly, the comprehensive weighting method of game theory is used to allocate weights to establish a construction The noise evaluation model in the environment is used to obtain the noise score in the construction environment to evaluate the noise impact of the construction environment and conduct noise management, which greatly improves the scientific nature of the evaluation model.
