Description

Technical Field

[0001] The present invention relates to the technical field of remote management of municipal engineering construction sites, and in particular to a remote management system for municipal engineering construction sites. Background Art

[0002] With the acceleration of urbanization, the scale of municipal engineering construction continues to expand. During construction, dust and noise issues not only impact the surrounding environment and residents' lives, but also pose a threat to the health and safety of construction workers. Traditional construction management methods often rely on manual on-site supervision and management, failing to comprehensively monitor and address dust and noise in a timely and effective manner. Therefore, a system is needed that can monitor dust and noise in real time and enable remote management.

[0003] The following problems still exist in the existing technology: 1. When adjusting the operating parameters of the spray dust suppression equipment at the construction site, the spray angle and spray flow rate of the spray dust suppression equipment are not dynamically adjusted in combination with the wind speed changes at the construction site, which reduces the dust suppression effect of the spray dust suppression equipment, makes it impossible to accurately intercept dust and difficult to fully absorb and settle dust, and ultimately fails to effectively ensure that the air quality of the construction site and surrounding areas meets the standards.

[0004] 2. The working priority of the mobile dust reduction equipment was not allocated according to the air pollution diffusion situation of the construction site itself and the living conditions of the residents that may be affected. The differences in air pollution diffusion in different areas within the construction site were not fully considered, and the high-incidence areas and diffusion paths of dust could not be accurately identified. As a result, the mobile dust reduction equipment could not focus on the prevention and control of pollution sources and key transmission areas in a timely manner. On the other hand, the residential distribution of surrounding residents was ignored, and construction sites close to sensitive areas such as residential areas, schools, and hospitals were not included in the priority dust reduction category, resulting in residents being exposed to excessive dust environments for a long time, which not only endangered public health, but also easily caused dissatisfaction among surrounding residents with the construction project, greatly affecting the overall effectiveness and social benefits of the construction. Summary of the Invention

[0005] In view of this, in order to solve the problems raised in the above background technology, a remote management system for municipal engineering construction sites is proposed.

[0006] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides a remote management system for municipal engineering construction sites, including: an air quality health assessment module, which is used to record the target municipal engineering construction site as the target construction site, collect the air parameter values ​​of each key area in the target construction site, and evaluate whether the air quality of each key area is healthy. If it is unhealthy, the spray dust reduction equipment adjustment module is executed; if it is healthy, the construction site noise monitoring module is executed.

[0007] The spray dust suppression equipment adjustment module is used to record key areas with unhealthy air quality as target areas, extract the wind speed corresponding to each target area, start the spray dust suppression equipment in each target area, and remotely adjust the operating parameters of the spray dust suppression equipment in each target area.

[0008] The air quality improvement assessment module is used to collect the air parameter values ​​of each target area during the operation of the spray dust reduction equipment, and evaluate whether the air quality of each target area has been improved. If not, the mobile dust reduction equipment working module is executed; if so, the construction site noise monitoring module is executed.

[0009] The mobile dust reduction equipment working module is used to record the target areas where the air quality has not improved as key pollution areas, extract the locations of each key pollution area, start the mobile dust reduction equipment at the target construction site, collect basic information corresponding to each key pollution area, and confirm the working priority of the mobile dust reduction equipment.

[0010] The construction site noise monitoring module is used to collect the noise intensity corresponding to each monitoring point in each construction time period at the target construction site, and evaluate whether there is a noise exceeding standard problem in each construction time period. If so, the construction time period with the noise exceeding standard problem will be recorded as a noise time period, and the on-site construction personnel will be notified in time to take noise reduction measures for each noise time period.

[0011] The noise reduction effect evaluation and feedback module is used to re-collect the noise intensity corresponding to each monitoring point in each noise time period after the noise reduction measures in each noise time period are completed, and evaluate whether the noise reduction effect of each noise time period meets the standard. If it does not meet the standard, feedback will be provided.

[0012] The database is used to store the standard values ​​corresponding to various air parameters in each key area of ​​the construction site, store the initial spray flow rate required to set the unit air quality health deviation, store the required increase in spray angle and spray flow rate corresponding to the unit wind speed, and store the noise intensity threshold corresponding to each construction time period.

[0013] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention improves the dust suppression effect of the spray dust suppression equipment by dynamically adjusting the spray angle and spray flow rate of the spray dust suppression equipment in combination with the wind speed changes at the construction site when adjusting the operating parameters of the spray dust suppression equipment at the construction site, helping to accurately intercept dust and fully absorb and settle dust, and ultimately effectively ensuring that the air quality of the construction site and surrounding areas meets the standards.

[0014] (2) The present invention allocates the working priority of the mobile dust reduction equipment according to the air pollution diffusion situation of the construction site itself and the living conditions of the residents that may be affected, fully considers the differences in air pollution diffusion in different areas within the construction site, accurately identifies the high-incidence areas and diffusion paths of dust, and enables the mobile dust reduction equipment to focus on the prevention and control of pollution sources and key transmission areas in a timely manner. On the other hand, the construction sections close to sensitive areas such as residential areas, schools, and hospitals are included in the priority dust reduction category to avoid residents from being exposed to excessive dust environments for a long time, thereby avoiding harm to public health and greatly reducing the impact on the overall effectiveness and social benefits of construction.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1 As shown, the present invention provides a remote management system for municipal engineering construction sites, including: an air quality health assessment module, a spray dust reduction equipment adjustment module, an air quality improvement assessment module, a mobile dust reduction equipment working module, a construction site noise monitoring module, a noise reduction effect evaluation feedback module and a database.

[0021] Both the spray dust reduction equipment adjustment module and the construction site noise monitoring module are connected to the air quality health assessment module, the spray dust reduction equipment adjustment module is connected to the air quality improvement assessment module, the air quality improvement assessment module is connected to the mobile dust reduction equipment working module, the air quality improvement assessment module is connected to the construction site noise monitoring module, the construction site noise monitoring module is connected to the noise reduction effect evaluation feedback module, and the air quality health assessment module, the spray dust reduction equipment adjustment module and the construction site noise monitoring module are all connected to the database.

[0022] The air quality health assessment module is used to record the target municipal engineering construction site as the target construction site, collect the air parameter values ​​in each key area of ​​the target construction site, and evaluate whether the air quality in each key area is healthy. If it is unhealthy, the spray dust reduction equipment adjustment module is executed; if it is healthy, the construction site noise monitoring module is executed.

[0023] It should be noted that the air parameter values ​​in the key areas of the target construction site are collected by air quality monitoring equipment deployed in the key areas.

[0024] In a specific embodiment of the present invention, the key areas include but are not limited to the entrances and exits of the target construction site, material storage areas, construction work surfaces and earth excavation areas, and the air parameters include but are not limited to inhalable particulate matter (PM10, PM2.5) and total suspended particulate matter (TSP).

[0025] In a specific embodiment of the present invention, the specific process of evaluating whether the air quality in each key area is healthy is as follows: A1, record the air parameter value in each key area as air ij , where i represents the number of the key area, i=1,2,...,n, and j represents the number of the air parameter, j=1,2,...,m.

[0026] A2. Extract the standard values ​​of each air parameter corresponding to each key area of ​​the construction site from the database and record them as

[0027] A3. Calculate the air quality health index β for each key area i , Wherein, Δair represents the set allowable air parameter deviation value, and m represents the number of air parameters.

[0028] See also Figure 2 As shown, A4, the air quality health index of each key area is compared with the set reference air quality health index. If the air quality health index of a key area is greater than or equal to the set reference air quality health index, it indicates that the air quality of the key area is healthy; otherwise, it indicates that the air quality of the key area is unhealthy.

[0029] The spray dust suppression equipment adjustment module is used to record key areas with unhealthy air quality as target areas, extract the wind speed corresponding to each target area, start the spray dust suppression equipment in each target area, and remotely adjust the operating parameters of the spray dust suppression equipment in each target area.

[0030] It should be noted that the wind speed corresponding to each target area is collected by a wind speed sensor.

[0031] In a specific embodiment of the present invention, the operating parameters include spray angle and spray flow rate.

[0032] In a specific embodiment of the present invention, the specific process of remotely adjusting the operating parameters of the spray dust suppression equipment in each target area is as follows: B1, extracting the initial spray flow rate required for the unit air quality health deviation from the database and recording it as Q 初 .

[0033] B2. Extract the required increase in spray angle and spray flow rate corresponding to unit wind speed from the database and record them as θ0 and Q0 respectively.

[0034] It should be noted that when the wind speed in the target area increases, the ultrasonic wind vane placed in the target area will monitor the current wind direction. If the spray angle of the dust suppression equipment is not adjusted, the water mist will be blown away from the dust source and will not be able to effectively contact the dust particles. Therefore, the spray angle of the dust suppression equipment in the target area needs to be adjusted to face the current wind direction, so that the water mist can go against the direction of dust diffusion and actively intercept the dust. At the same time, the increase in wind speed will shorten the residence time of the water mist in the air. Increasing the spray flow rate can release more water mist per unit time, thereby increasing the probability of water mist contact with dust within a limited time and space.

[0035] B3. The wind speed corresponding to each target area is recorded as v g , where g represents the number of the target area, g = 1, 2, ..., r.

[0036] B4. Extract the air quality health index of each target area and record it as

[0037] B5. Adjust the spray angle of the spray dust suppression equipment in each target area toward the wind direction θ0*v g , adjust the spray flow rate of the spray dust suppression equipment in each target area to Among them, β′ represents the reference air quality health index.

[0038] The embodiment of the present invention improves the dust reduction effect of the spray dust reduction equipment by dynamically adjusting the spray angle and spray flow rate of the spray dust reduction equipment in combination with the wind speed changes at the construction site when adjusting the operating parameters of the spray dust reduction equipment at the construction site, helping to accurately intercept dust and fully absorb and settle dust, and ultimately effectively ensuring that the air quality of the construction site and surrounding areas meets the standards.

[0039] The air quality improvement assessment module is used to collect the air parameter values ​​of each target area during the operation of the spray dust reduction equipment, and evaluate whether the air quality of each target area has improved. If not, the mobile dust reduction equipment working module is executed; if improved, the construction site noise monitoring module is executed.

[0040] It should be noted that the air parameter values ​​of each target area during the operation of the spray dust suppression equipment are also collected by air quality monitoring equipment.

[0041] In a specific embodiment of the present invention, the specific process of evaluating whether the air quality of each target area has been improved is as follows: C1, based on the air parameter values ​​of each target area during the operation of the spray dust suppression equipment, the air quality health index of each target area during the operation of the spray dust suppression equipment is calculated in the same way as the calculation method of the air quality health index of each key area.

[0042] C2. Calculate the air quality improvement of each target area χ g , Among them, Δβ represents the healthy deviation of air quality of the set reference, and e represents the natural constant.

[0043] See also Figure 3 As shown, C3, the air quality improvement degree of each target area is compared with the air quality improvement degree of the set reference. If the air quality improvement degree of a target area is greater than or equal to the air quality improvement degree of the set reference, it indicates that the air quality of the target area has improved; otherwise, it indicates that the air quality of the target area has not improved.

[0044] The mobile dust reduction equipment working module is used to record the target areas where the air quality has not improved as key pollution areas, extract the locations of each key pollution area, start the mobile dust reduction equipment at the target construction site, collect basic information corresponding to each key pollution area, and confirm the working priority of the mobile dust reduction equipment.

[0045] It should be noted that the locations of the key pollution areas are directly extracted from the construction drawings of the target construction site.

[0046] In a specific embodiment of the present invention, the basic information includes the values ​​of each air parameter corresponding to each monitoring time period within the scope, the number of key residential areas within the scope, and the location of each key residential area.

[0047] It should be noted that the air parameter values ​​corresponding to each monitoring time period within the scope are also collected by air quality monitoring equipment, and the number of key residential areas within the scope and the locations of each key residential area are extracted from the geographical distribution map within the scope.

[0048] In a specific embodiment of the present invention, the key residential areas include but are not limited to schools, parks and residential buildings.

[0049] In a specific embodiment of the present invention, the specific process of confirming the working priority of the mobile dust reduction equipment is as follows: D1, extracting the air parameter values ​​corresponding to each monitoring time period within the scope, the number of key focus residential points within the scope and the location of each key focus residential point from the basic information corresponding to each key pollution area, and calculating the air pollution diffusion degree of each key pollution area based on this. and human exposure risk index δ p , where p represents the number of the key pollution area, p = 1, 2, ..., q.

[0050] It should be noted that the specific process of calculating the air pollution diffusion degree of each key pollution area is: based on the air parameter values ​​corresponding to each key pollution area in each monitoring time period, the air quality health index corresponding to each key pollution area in each monitoring time period is calculated in the same way as the calculation method of the air quality health index of each key area.

[0051] With the monitoring time period as the horizontal axis and the air quality health index as the vertical axis, the air quality deviation curve within the corresponding range of each key pollution area is constructed, and the slope value is located from the curve as the air quality decline rate within the corresponding range of each key pollution area, which is marked as K p .

[0052] Calculate the air pollution diffusion degree of each key pollution area Wherein, K′ represents the air quality decrease rate of the set reference.

[0053] In a specific embodiment of the present invention, the specific process of calculating the human exposure risk index of each key pollution area is as follows: E1, the number of key residential areas within the corresponding range of each key pollution area is recorded as ε p .

[0054] E2. Based on the location of each key pollution area and the location of each key residential area, the distance between each key pollution area and its corresponding key residential area is obtained, and the minimum distance is extracted from them, which is recorded as L p .

[0055] E3. Calculate the human exposure risk index δ for each key pollution area p , Among them, ε′ and L′ represent the number and distance of key settlements for reference, respectively.

[0056] D2. Calculate the dust fall urgency θ corresponding to each key pollution area p , Among them, a1 and a2 represent the weights of the dustfall urgency assessment corresponding to the set air pollution diffusion and human exposure risk index, respectively, and a1+a2=1.

[0057] In a specific embodiment of the present invention, the setting value of a1 is 0.5, and the setting value of a2 is 0.5. When calculating the dustfall urgency corresponding to each key pollution area, the air pollution diffusion and the human exposure risk index are both crucial, and it is difficult to simply determine which one is more important. The air pollution diffusion reflects the spread range and speed of pollutants in the air. If the diffusion is high, it may lead to pollution on a larger scale, affecting environmental quality and ecological balance. The human exposure risk index is directly related to human health. If the index is high, the threat to human health is greater. The two are interrelated and indispensable in the dustfall urgency assessment. It is impossible to simply think that one factor is more important, and their impact on the dustfall urgency needs to be comprehensively considered.

[0058] D3. Sort the dust reduction urgency corresponding to each key pollution area from large to small, and use the key pollution areas corresponding to the sorted dust reduction urgency as the working priority areas for mobile dust reduction equipment.

[0059] The embodiment of the present invention allocates the working priority of the mobile dust reduction equipment according to the air pollution diffusion situation of the construction site itself and the living conditions of the residents that may be affected, fully considers the differences in air pollution diffusion in different areas within the construction site, and accurately identifies the high-incidence areas and diffusion paths of dust, so that the mobile dust reduction equipment can focus on the prevention and control of pollution sources and key transmission areas in a timely manner. On the other hand, construction sections close to sensitive areas such as residential areas, schools, and hospitals are included in the priority dust reduction category to avoid residents from being exposed to excessive dust environments for a long time, thereby avoiding harm to public health and greatly reducing the impact on the overall effectiveness and social benefits of construction.

[0060] The construction site noise monitoring module is used to collect the noise intensity corresponding to each monitoring point in each construction time period at the target construction site, and evaluate whether there is a noise exceeding standard problem in each construction time period. If so, the construction time period with the noise exceeding standard problem will be recorded as a noise time period, and the on-site construction personnel will be notified in time to take noise reduction measures for each noise time period.

[0061] It should be noted that the noise intensity corresponding to each monitoring point at the target construction site during each construction time period is collected by a fixed noise monitor installed at each monitoring point.

[0062] In a specific embodiment of the present invention, the specific process of evaluating whether there is a noise exceeding standard problem in each construction time period is as follows: F1, the noise intensity corresponding to each monitoring point in each construction time period of the target construction site is compared with the noise intensity threshold corresponding to each construction time period stored in the database; if the noise intensity corresponding to a monitoring point in a certain construction time period is greater than the noise intensity threshold corresponding to the construction time period, then the monitoring point in the construction time period is recorded as a noise exceeding standard monitoring point, and the number of noise exceeding standard monitoring points in each construction time period is counted, which is recorded as τ x , where x represents the number of the construction time period, x=1,2,...,y.

[0063] F2. Calculate the noise exceeding standard index ω for each construction period x , Where τ′ represents the number of permitted noise exceeding standard monitoring points.

[0064] F3. Compare the noise excess index of each construction period with the set reference noise excess index. If the noise excess index of a construction period is greater than the set reference noise excess index, it indicates that there is a noise excess problem in this construction period. Otherwise, it indicates that there is no noise excess problem in this construction period.

[0065] The noise reduction effect evaluation and feedback module is used to re-collect the noise intensity corresponding to each monitoring point in each noise time period after the noise reduction measures in each noise time period are completed, and evaluate whether the noise reduction effect in each noise time period meets the standard. If not, feedback is provided.

[0066] It should be noted that the noise intensity corresponding to each monitoring point in each noise time period is also collected by a fixed noise monitor installed at each monitoring point.

[0067] In a specific embodiment of the present invention, the specific process of evaluating whether the noise reduction effect of each noise time period meets the standard is: the specific process of evaluating whether the noise reduction effect of each noise time period meets the standard is: based on the noise intensity corresponding to each monitoring point in each noise time period, the noise excess index of each noise time period is calculated in the same way as the noise excess index of each construction time period, and compared with the set reference noise excess index. If the noise excess index of a noise time period is less than or equal to the set reference noise excess index, it indicates that the noise reduction effect of the noise time period meets the standard; otherwise, it indicates that the noise reduction effect of the noise time period does not meet the standard.

[0068] The database is used to store standard values ​​for various air parameters in key areas of the construction site, the initial spray flow rate required to set a unit air quality health deviation, the required increase in spray angle and spray flow rate corresponding to a unit wind speed, and noise intensity thresholds corresponding to each construction time period. The data sources in the database of this embodiment are shown in Table 1.
