[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 An embodiment of the present invention provides a technical solution for identifying environmental risks at infrastructure line construction sites: an infrastructure line construction site environmental risk identification system, including a three-dimensional ranging risk level determination module, a natural environment risk level determination module, a construction status risk level determination module, an environmental risk preliminary assessment level determination module and a construction site environmental risk judgment module.

[0022] The three-dimensional distance measurement risk level determination module obtains the three-dimensional distance measurement data of the infrastructure line construction site, and determines the three-dimensional distance measurement risk level of the infrastructure line construction site based on the obtained three-dimensional distance measurement data of the infrastructure line construction site.

[0023] like Figure 2 As shown, the specific analysis process includes: the three-dimensional distance measurement data of the infrastructure line construction site specifically includes the terrain difference of the infrastructure line construction site, the shortest distance between the obstacle and the infrastructure line construction site, and the highest ground slope of the infrastructure line construction site; based on the acquired three-dimensional distance measurement data of the infrastructure line construction site, a three-dimensional distance measurement risk signal is obtained by comprehensive analysis, and the three-dimensional distance measurement risk signal is used as an analysis basis for determining the three-dimensional distance measurement risk level of the infrastructure line construction site; the three-dimensional distance measurement risk signal is compared with the three-dimensional distance measurement risk threshold stored in the database; if the three-dimensional distance measurement risk signal is not lower than the three-dimensional distance measurement risk threshold, the three-dimensional distance measurement risk level of the infrastructure line construction site corresponding to the three-dimensional distance measurement risk signal is level one; if the three-dimensional distance measurement risk signal is lower than the three-dimensional distance measurement risk threshold, the three-dimensional distance measurement risk level of the infrastructure line construction site corresponding to the three-dimensional distance measurement risk signal is level zero.

[0024] The terrain difference refers to the maximum height difference of the construction site, indicating the vertical distance difference of the construction site. In the construction of infrastructure lines, the greater the terrain difference, the greater the terrain undulation of the construction site, and the higher the construction difficulty and safety risk. The shortest distance between the obstacle and the infrastructure line construction site refers to the shortest horizontal distance between the construction site and the potential obstacle. Obstacles can be buildings, trees, poles, roads, hills, etc., which hinder the passage of construction equipment and personnel or affect the quality of construction. The highest ground slope refers to the maximum value of the ground slope at the construction site, indicating the steepest slope on the construction site, usually expressed as the ratio of height change to horizontal distance.

[0025] Through the precise measurement and analysis of 3D ranging data (terrain difference, obstacle distance, ground slope), the actual environment of the construction site can be objectively and accurately reflected, avoiding the influence of human subjective factors. After comprehensive analysis of the 3D ranging data, a 3D ranging risk signal is generated, which can clearly mark the potential risk areas at the construction site and improve the accuracy of risk assessment. By comparing the 3D ranging risk signal with the stored risk threshold, the risk level of the construction site (such as level 1 and level 0) can be automatically determined, which helps to quickly identify risks. Automated risk monitoring not only saves labor costs, but also improves real-time performance.

[0026] Furthermore, the specific analysis process of the three-dimensional ranging risk signal is as follows: ; In the formula, It is a three-dimensional ranging risk signal. The construction site of the infrastructure line has poor terrain. The shortest distance between the obstacle and the infrastructure line construction site, The highest ground slope at the infrastructure line construction site. For setting The compensation factor, For setting The compensation factor, For setting The compensation factor of , e is a natural constant.

[0027] In this embodiment, when calculating each formula, each parameter may be normalized first as needed.

[0028] , and It is an important feature of the geographical environment of the construction site. These factors have a direct impact on construction safety, construction efficiency and construction quality. By integrating these factors into the calculation of the 3D ranging risk signal, the geographical risk of the construction site can be assessed more accurately, avoiding ignoring local risks, and taking into account complex risk situations that cannot be fully described by a single factor, so as to have a more comprehensive understanding of the geographical environment and potential hazards of the construction site.

[0029] In this embodiment, each compensation factor is obtained from a database. For example, the terrain difference of the infrastructure line construction site measured historically, the shortest distance between the obstacle and the infrastructure line construction site, the highest slope of the ground at the infrastructure line construction site and the , , The mapping set of compensation factors is obtained , , Corresponding , , compensation factor.

[0030] The natural environment risk level determination module analyzes the natural environment of the infrastructure line construction site and determines the natural environment risk level of the infrastructure line construction site.

[0031] The specific analysis process is as follows: obtaining the natural environment data of the infrastructure line construction site, which specifically includes the natural environment temperature deviation rate, the natural environment humidity deviation rate, and the natural environment wind speed of the construction site; based on the obtained natural environment data of the infrastructure line construction site, a comprehensive analysis is performed to obtain a natural environment risk signal, which is used as an analysis basis for determining the natural environment risk level of the infrastructure line construction site; comparing the natural environment risk signal with the natural environment risk threshold stored in the database; if the natural environment risk signal is not lower than the natural environment risk threshold, then the natural environment risk level of the infrastructure line construction site corresponding to the natural environment risk signal is level one; if the natural environment risk signal is lower than the natural environment risk threshold, then the natural environment risk level of the infrastructure line construction site corresponding to the natural environment risk signal is level zero.

[0032] The temperature deviation rate refers to the difference between the actual temperature at the construction site and the standard or reference temperature, usually expressed as a percentage. This deviation rate reflects the degree of deviation between the actual ambient temperature and the expected temperature. The humidity deviation rate refers to the difference between the actual humidity at the construction site and the standard humidity, usually expressed as a percentage. The wind speed refers to the wind speed at the construction site, usually in meters per second (m / s) or kilometers per hour (km / h). The wind speed directly affects the material handling, equipment stability and safety of construction workers during the construction process. The deviation rate is the ratio of the absolute value of the difference between the actual value and the reference value to the reference value.

[0033] Real-time monitoring and analysis of natural environmental data (temperature, humidity, wind speed) can provide an objective and accurate basis for risk assessment, avoid human interference and subjective bias, and ensure the scientificity and accuracy of risk assessment. Automatically assessing risk levels by comparing with risk thresholds not only improves monitoring efficiency, but also reduces omissions in manual operations and ensures the real-time nature of risk management.

[0034] Changes in the natural environment (such as high temperature, high humidity, and strong winds) have a negative impact on construction equipment, personnel safety, and construction quality. By accurately evaluating these factors, targeted risk prevention measures can be taken, such as limiting operations under high-risk weather conditions and adding protective facilities, thereby avoiding safety hazards caused by the natural environment. Automatic assessment of natural environmental risk levels can improve the level of intelligent management of construction sites, help move towards digital and automated management models, and provide more efficient and reliable safety guarantees for future construction projects.

[0035] The specific analysis process of natural environment risk signals is as follows: ; In the formula, For natural environmental risk signals, is the natural environment temperature deviation rate at the construction site, is the humidity deviation rate of the natural environment at the construction site, is the natural environment wind speed at the construction site, For setting The compensation factor, For setting The compensation factor, For setting compensation factor.

[0036] , and These three factors can monitor and dynamically evaluate the environmental status of the construction site in real time, monitor and calculate natural environmental risk signals in real time, promptly detect natural environmental anomalies, reduce their negative impact on construction progress and safety, ensure the safety of construction personnel, and better deploy adaptive measures to ensure that the construction site can operate stably, enhance prediction and early warning capabilities, and improve the sustainability of construction projects.

[0037] The construction status risk level determination module analyzes the construction status of the infrastructure line construction site and determines the construction status risk level of the infrastructure line construction site.

[0038] The specific analysis process is as follows: obtaining the construction status data of the infrastructure line construction site, which specifically includes the attendance rate of construction personnel at the construction site, the normal operation rate of construction equipment at the construction site, and the decibel value of construction noise at the construction site; based on the obtained construction status data of the infrastructure line construction site, a comprehensive analysis is performed to obtain the construction status risk signal, which is used as the analysis basis for determining the construction status risk level of the infrastructure line construction site.

[0039] The attendance rate of construction personnel refers to the ratio of the number of construction personnel who actually arrive at the construction site within the specified time to the number of planned arrivals, reflecting the attendance of personnel at the construction site, usually expressed as a percentage. The normal operation rate of construction equipment refers to the ratio between the number of equipment that can operate normally at the construction site within the specified time and the total number of equipment, reflecting the availability of construction equipment. The decibel value of construction noise refers to the noise intensity at the construction site, usually measured in decibels (dB). The decibel value of noise reflects the level of noise pollution generated during the construction process.

[0040] By monitoring the attendance rate of construction personnel, we can know in real time whether there are any absences or delays in arrival, and take supplementary measures in time to ensure the smooth progress of construction and avoid delays in project progress or safety accidents due to staff shortages. The normal operation rate of construction equipment is directly related to construction quality and efficiency. By monitoring the normal operating status of equipment and timely discovering equipment failures, wear and tear or poor operation problems, we can reduce equipment downtime, ensure construction progress, and avoid safety hazards caused by equipment failure. The noise level at the construction site will affect the staff and the surrounding environment. By monitoring the noise decibel value at the construction site, we can effectively control noise pollution, ensure that the working environment at the construction site meets safety and health standards, and avoid accidents or health problems caused by excessive noise.

[0041] By collecting real-time data such as the attendance rate of construction personnel, the operating status of construction equipment, and environmental data such as noise, we can fully understand the real-time operation status of the construction site, which helps to promptly discover safety hazards in the construction process, such as insufficient personnel, equipment failure, or noise pollution.

[0042] Furthermore, the specific analysis process of the construction status risk signal is as follows: ; In the formula, It is a risk signal of construction status. The attendance rate of construction workers at the construction site. The normal operation rate of construction equipment at the construction site, is the decibel value of construction noise at the construction site, For setting The compensation factor, For setting The compensation factor, For setting compensation factor.

[0043] The calculation of construction status risk signals can comprehensively consider multiple factors such as personnel attendance, equipment operation and noise level, so as to comprehensively evaluate the operating status of the construction site, more accurately reflect the overall risk status of the construction site, and quantify the safety risks of the construction site. Combining these indicators can help the construction site discover safety hazards earlier.

[0044] The construction status risk signal is compared with the construction status risk threshold stored in the database; if the construction status risk signal is not lower than the construction status risk threshold, the construction status risk level of the infrastructure line construction site corresponding to the construction status risk signal is level one; if the construction status risk signal is lower than the construction status risk threshold, the construction status risk level of the infrastructure line construction site corresponding to the construction status risk signal is level zero.

[0045] By comparing the actual collected construction status risk signals with the preset risk thresholds, the errors caused by human subjective judgment are eliminated, making risk assessment more objective and reliable. Managers do not need to rely on experience and judgment, but can make accurate analysis and decisions based on data. This automated response mechanism greatly improves the efficiency of construction site management and can take measures to prevent risks from occurring as soon as possible.

[0046] The environmental risk preliminary assessment level determination module determines the preliminary assessment level of the environmental risk at the infrastructure line construction site based on the three-dimensional ranging risk level, natural environment risk level and construction status risk level of the infrastructure line construction site.

[0047] The specific analysis process is: accumulate the three-dimensional distance measurement risk level, natural environment risk level and construction status risk level of the infrastructure line construction site to obtain the initial assessment level of the environmental risk of the infrastructure line construction site.

[0048] The risks at a construction site are usually multifaceted, and a single-dimensional assessment cannot fully reflect the actual risk situation at the site. By accumulating three important factors, namely, 3D distance measurement, natural environment, and construction status, the impact of different risk sources can be fully considered, providing a more valuable comprehensive risk view, which can more accurately predict and identify potential safety hazards and environmental risks. This early risk identification helps reduce the probability of accidents.

[0049] The construction site environmental risk judgment module analyzes the quality of data collection at the infrastructure line construction site, and combines the initial assessment level of the infrastructure line construction site environmental risk to determine whether there are risks in the infrastructure line construction site environment: if there are risks in the infrastructure line construction site environment, the monitoring center will automatically issue an early warning; if there are no risks in the infrastructure line construction site environment, the infrastructure line construction site environment will continue to be analyzed.

[0050] The specific analysis process is as follows: obtaining the data collection quality data of the infrastructure line construction site, and based on the obtained data collection quality data of the infrastructure line construction site, comprehensively analyzing to obtain the data collection quality factor, and using the data collection quality factor as the analysis basis for judging whether there is a risk in the infrastructure line construction site environment; comparing the data collection quality factor with the data collection quality threshold stored in the database; If the data collection quality factor is not lower than the data collection quality threshold, the environmental risk level of the infrastructure line construction site is increased by one level from the initial assessment level of the infrastructure line construction site environmental risk; if the data collection quality factor is lower than the data collection quality threshold, the environmental risk level of the infrastructure line construction site is unchanged from the initial assessment level of the infrastructure line construction site environmental risk; the environmental risk level of the infrastructure line construction site is compared with the basic environmental risk level of the infrastructure line construction site stored in the database; if the environmental risk level of the infrastructure line construction site is not lower than the basic environmental risk level of the infrastructure line construction site, there is a risk in the infrastructure line construction site environment, and the monitoring center automatically issues an early warning; if the environmental risk level of the infrastructure line construction site is lower than the basic environmental risk level of the infrastructure line construction site, there is no risk in the infrastructure line construction site environment, and the infrastructure line construction site environment continues to be analyzed.

[0051] By comparing the data collection quality factor with the threshold, the reliability of environmental risk assessment can be effectively improved to avoid misjudgments or neglect of potential risks due to substandard data quality. The data collection quality factor can detect and correct the accuracy of risk assessments that is reduced due to inaccurate data. If the data quality is not high, timely adjustment of risk judgments can help avoid misleading decisions.

[0052] By dynamically comparing the data collection quality factor and the environmental risk level, the risk changes at the construction site can be monitored in real time. If the data collection quality does not meet the standard, the system can automatically increase the environmental risk level and trigger the early warning mechanism to ensure a rapid response to emergencies. By comprehensively considering the data collection quality, the initial environmental risk assessment level and the basic level, the safety status of the construction site can be comprehensively evaluated from multiple dimensions, which not only improves the accuracy of risk assessment, but also better adapts to risk changes in complex environments.

[0053] Furthermore, the quality data of data collection at the infrastructure line construction site specifically includes data collection repetition rate, data collection error rate, and data collection delay.

[0054] The data collection repetition rate refers to the proportion of data that is repeatedly collected during the data collection process. Duplicate data is usually meaningless, increases the storage burden and affects subsequent data processing and analysis. The data collection error rate refers to the proportion of erroneous data collected during the data collection process. Erroneous data includes biased, missing or invalid data, which usually affects the accuracy of data analysis and decision-making. Data collection delay refers to the time interval from data generation or event occurrence to data collection and recording. It is usually used to measure the response speed of the data acquisition system, especially in real-time monitoring systems. The size of the delay directly affects the real-time and responsiveness of the system.

[0055] Data collection quality factor, the specific analysis process is: ; In the formula, is the data acquisition quality factor, is the data collection repetition rate, is the data collection error rate, is the data collection delay, For setting The compensation factor, For setting The compensation factor, For setting compensation factor.

[0056] Considering each parameter (repetition rate, error rate, delay) alone cannot fully reflect the overall quality of data collection. By combining these factors to calculate the data collection quality factor, we can more comprehensively measure the performance of the data collection system and understand its comprehensive level in terms of accuracy, reliability and timeliness. The system can monitor the health of data collection in real time and promptly detect anomalies or problems in the collection process. Based on the changes in the quality factor, it can provide an early warning mechanism for the system.

The calculated natural environment risk signal is 8.395, which is not lower than the natural environment risk threshold of 8. The natural environment risk level of the infrastructure line construction site corresponding to the natural environment risk signal is level one.

The calculated construction status risk signal is 10.688, which is not less than the construction status risk threshold of 8. The construction status risk level of the infrastructure line construction site corresponding to the construction status risk signal is level one. The three-dimensional ranging risk level, natural environment risk level and construction status risk level of the infrastructure line construction site are accumulated, and the initial assessment level of the environmental risk of the infrastructure line construction site is level two.
