Description

Technical Field

[0001] The present invention relates to the technical field of urban facility status detection, and in particular to a method and system for urban facility status detection and analysis. Background Art

[0002] In recent years, with the rise of the concept of smart cities, the intelligent management of urban facilities has gradually become an important part of urban planning and management. Urban facilities, including traffic lights, bridges, public buildings, etc., are essential to maintaining the basic functions of the city. Traditionally, the maintenance and management of these facilities rely on regular inspections and manual monitoring, which is not only time-consuming and labor-intensive, but also inefficient. With the development of the Internet of Things (IoT) technology, real-time data collection and processing have become possible. A large number of sensors and monitoring equipment have been deployed in every corner of the city to collect real-time data on the status of urban facilities.

[0003] Against this technological backdrop, data-driven urban facility management methods have begun to emerge. These methods improve the efficiency and accuracy of urban facility maintenance by analyzing large amounts of data collected from various sensors and monitoring devices. For example, by analyzing traffic flow data, the control of traffic lights can be optimized to reduce traffic congestion. Similarly, analyzing energy consumption data of public buildings can help save energy and reduce operating costs.

[0004] Although data-driven approaches have made significant progress in urban facility management, existing technologies still have some limitations. First, data integration and preprocessing are often scattered across different systems and platforms, lacking effective integration, which limits the depth and breadth of data analysis. Second, existing analysis methods mostly focus on the management of a single type of facility and lack a comprehensive assessment of urban facilities as a whole. In addition, environmental impact assessments are usually not fully considered, which is crucial for promoting sustainable urban development. Summary of the invention

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0032] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0033] Example 1

[0034] Reference Figure 1 , as an embodiment of the present invention, provides a method for detecting and analyzing the status of urban facilities, comprising:

[0035] S1: Collect real-time data of urban facilities, pre-process the real-time data and integrate it into the central database.

[0036] Furthermore, real-time data on urban facilities includes environmental impact data, drone images and sensor data, pedestrian flow and activity data, usage and operation data, and failure and maintenance records.

[0037] It should be noted that integration into the central database includes data cleaning of real-time data, removal of irrelevant and erroneous data, conversion of data into a uniform format using Z-score standardization, combining drone image data with sensor data to provide a multidimensional view, storing the pre-processed data in the central database, and establishing data consistency and accessibility.

[0038] It should also be noted that the collection of real-time data provides immediate and comprehensive information for the management and maintenance of urban facilities. The use of this comprehensive data makes the decision-making process more data-driven, thereby improving the efficiency and effectiveness of urban facility management. For example, by analyzing pedestrian flow and activity data, the use and planning of public spaces can be optimized, while the analysis of failure and maintenance records can help prevent future facility failures. Data cleaning and standardization ensure the quality and comparability of data, which is a prerequisite for effective analysis. The combination of drone images and sensor data provides a multi-dimensional view of the status of urban facilities, which is crucial for understanding complex urban environments. Storing these pre-processed data in a central database not only improves the accessibility of the data, but also ensures the consistency of analysis. This centralized data management method greatly improves urban managers' understanding and response capabilities to the status of urban facilities.

[0039] S2: Through the central database, an integrated environmental impact assessment model for urban facilities is constructed to assess the impact of urban facilities on the environment.

[0040] Furthermore, constructing the urban facility integrated environmental impact assessment model includes constructing the urban facility integrated environmental impact assessment model through the central database based on the data collected in the central database, which is expressed as:

[0041]

[0042] Among them, F is the output value of the urban facility integrated environmental impact assessment model, the value range of F is [0, M], T is the assessment period, Λ(e -λt ,R) is the urban renewal function, λ is the decay index, R is the urban renewal rate, Θ(σ,δ,t) is the complex environment impact function, σ is volatility, δ is urban density, t is time, Ω(·) is the urban environment impact function, ψ i is the impact weight of the i-th city facility, is the environmental effect function of the i-th city facility over time, n is the number of cities, ρ i is the energy consumption coefficient of the i-th urban facility, P iis the passenger flow of the i-th urban facility, κ i is the adjustment coefficient of environmental impact factors, Q i (t) is the contribution of the i-th urban facility to the specific environmental parameters; the calculation of the complex environmental impact function Θ(σ,δ,t) is expressed as:

[0043]

[0044] Where μ is the mean of time, γ is the function growth rate, and t0 is the midpoint time; calculate the environmental effect function of the i-th urban facility over time It is expressed as:

[0045] φ i (t) = a i ·t+b i ·sin(c i ·t)

[0046] Among them, a i is the linear growth rate parameter, b i is the amplitude parameter, c i is the frequency parameter; calculate the contribution Q of the i-th urban facility to the specific environmental parameter i (t) is expressed as:

[0047]

[0048] Where m is the total number of pollutant types, w is ij is the contribution weight of the ith facility to the jth pollutant, AQI ij (t) is the air quality index contribution of the ith facility to the jth pollutant at time t.

[0049] It should be noted that the assessment of the impact of urban facilities on the environment includes assessing the impact of urban facilities on the environment based on the output value F of the integrated environmental impact assessment model of urban facilities; when F is greater than 0 and less than M / 2, the impact of urban facilities on the environment is small, and the urban facilities are environmentally friendly; when F is equal to M / 2, the impact of urban facilities on the environment reaches the threshold, the urban facilities are environmentally polluting, and the urban facilities are inspected and the pollution index is tested. If the pollution index is unqualified, the environmental impact factors of urban facilities are checked one by one, and carbon emissions of urban facilities are controlled; when F is greater than M / 2 and less than or equal to M, the impact of urban facilities on the environment is large, the urban facilities are environmentally destructive, the pollution index is unqualified, the environmental impact factors of urban facilities are checked one by one, carbon emissions of urban facilities are controlled, and the F result is recalculated after carbon emissions control.

[0050] It should also be noted that the urban facility integrated environmental impact assessment model integrates the operation data and environmental impact data of urban facilities to provide a comprehensive environmental impact assessment. This comprehensive assessment is very important for urban planners and environmental protectors because it can better understand the actual impact of urban facilities on the environment and formulate corresponding policies and measures accordingly. By considering the assessment cycle and urban renewal function, the urban facility integrated environmental impact assessment model can reflect the environmental impact of urban facilities over time, which helps to identify long-term trends and potential environmental risks, so as to take preventive measures. The urban facility integrated environmental impact assessment model determines the degree of impact of urban facilities on the environment by calculating the output value F. When the F value is lower than a certain threshold, it indicates that the relevant facilities are environmentally friendly, which is crucial to promoting sustainable urban development. When the F value reaches or exceeds a certain threshold, it means that the relevant urban facilities may be a source of environmental pollution. At this time, the use of the urban facility integrated environmental impact assessment model can guide urban managers to take corresponding investigation and control measures, such as carbon emission control, to reduce their negative impact on the environment.

[0051] S3: Based on the results of the urban facility environmental impact assessment, comprehensively assess the status of urban facilities and analyze potential problems and maintenance needs of urban facilities.

[0052] Furthermore, the comprehensive evaluation of the state of urban facilities includes taking the output value F of the urban facility integrated environmental impact assessment model as an input parameter based on the results of the urban facility environmental impact assessment, and comprehensively evaluating the state of urban facilities to calculate the comprehensive score S of the urban facility state, which is expressed as:

[0053]

[0054] Among them, λ i is the environmental impact factor of the i-th urban facility, F i is the output value of the urban facility integrated environmental impact assessment model for the i-th urban facility, μ i is the maintenance demand factor of the i-th city facility, D i is the number of failures of facilities in the ith city, R i is the utilization rate of the i-th urban facility, ∈ is the urban facility constant; when the comprehensive score S of the urban facility status is greater than or equal to the urban equipment status limit value Smax, the urban facility status is abnormal, the environmental impact is unqualified, the failure rate is high, and major maintenance, updating and replacement of the urban facilities are required.

[0055] It should be noted that the analysis of potential problems and maintenance needs of urban facilities includes checking the wear and tear, safety conditions, and utilization efficiency of urban facilities based on the comprehensive status detection results of urban facilities, maintaining, updating, and replacing urban facilities based on maintenance needs, recording the handling process of urban facilities in abnormal conditions, and storing data in a central database to generate abnormal data logs.

[0056] It should also be noted that by comprehensively considering multiple aspects of environmental impact and facility operation, an accurate assessment of the status of urban facilities can be provided, which is crucial for city managers because it can help identify which facilities need priority attention and maintenance. Through a comprehensive assessment of the status of facilities, managers can allocate resources more effectively and give priority to those facilities that have the greatest impact on the environment or are the most unstable in operation. This not only improves the efficiency of maintenance work, but also helps to improve the overall performance of urban facilities. By continuously monitoring and evaluating the environmental impact of facilities, it helps cities develop in a more sustainable direction and ensures that environmental protection is fully considered in urban facility management. When the status score of urban facilities exceeds the equipment status limit, it means that emergency intervention is required. Such a mechanism ensures timely maintenance of potential high-risk facilities, thereby reducing the negative impact that may be caused by facility failures. By recording the results of facility status detection in a central database and generating abnormal data logs, it can help city managers better understand the patterns and trends of facility failures and maintenance needs, thereby formulating more effective long-term maintenance strategies.

[0057] Example 2

[0058] An embodiment of the present invention provides a method for detecting and analyzing the status of urban facilities. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0059] First, real-time data collection of urban facilities was carried out, including environmental impact data, drone images and sensor data, human flow and activity data, usage rate and operation data, fault and maintenance records. These data were preprocessed and cleaned to remove irrelevant and erroneous data, and then converted into a unified format using Z-score standardization and integrated into the central database. Next, based on the data in the central database, an integrated environmental impact assessment model for urban facilities was constructed. The model comprehensively considers factors such as urban renewal rate, adjustment coefficient of environmental impact factors, energy consumption coefficient of facilities, human flow, and contribution of facilities to specific environmental parameters, such as air quality index contribution. Through this comprehensive approach, the environmental impact of each urban facility can be more accurately assessed. Finally, based on the results of the environmental impact assessment, a comprehensive assessment of the status of urban facilities was conducted, which included analyzing the wear and tear, safety, and efficiency of urban facilities, as well as necessary maintenance, renewal, or replacement of facilities based on maintenance needs. For facilities with abnormal status, detailed processing process records were made, and these data were statistically stored in the central database to generate abnormal data logs.

[0060] Refer to Table 1 to record and analyze the experimental data.

[0061] Table 1 Experimental data record table

[0062]

[0063] By comparing the environmental impact score F, maintenance demand score, failure rate, usage rate, pollutant emissions and comprehensive score S of different urban facilities, the beneficial effects of our invention can be seen. For example, the environmental impact score of the water treatment plant is higher, indicating that it has a greater negative impact on the environment. Correspondingly, its comprehensive score is also relatively high, indicating its impact on the environment and the urgent need for maintenance. Through this comprehensive assessment, urban facilities that need priority attention can be accurately identified, such as water treatment plants and power facilities, which have a greater impact on the environment and higher maintenance needs. Our invention is superior to traditional urban facility management methods because our invention not only considers the operating efficiency and reliability of the facilities, but also takes environmental impact into consideration. Compared with the existing technology, our invention provides a more comprehensive, data-driven urban facility status assessment method. By integrating multiple data sources and using advanced algorithms, it can more accurately identify potential problems and maintenance needs of urban facilities, which not only improves the efficiency of urban facility management, but also helps to promote cities to move towards sustainable development. Therefore, our invention is creative.
