Description

Technical Field

[0001] The present invention belongs to the technical field of civil engineering construction management, and specifically is an Internet-based construction temporary facility indicator early warning control system. Background Art

[0002] With the continuous expansion of the scale of construction projects and the increasing complexity of construction, the planning and control of temporary facilities such as office areas, living areas, and material storage areas have become extremely critical. If there are deviations in the indicators of temporary facilities, such as improper area allocation, lack of scientific facility layout, and unbalanced resource allocation, it is very likely to cause a series of adverse consequences such as delays in construction progress, cost overruns, and the breeding of safety hazards. In view of this, it is very important to build an early warning and control system for indicators of temporary facilities in construction.

[0003] There are some solutions related to the management and control of temporary facilities for construction in the prior art, which can provide auxiliary applications for early warning analysis to a certain extent. For example, a method and system for optimizing the layout of temporary facilities at a construction site with a Chinese patent publication number of CN118485550A, which obtains all tower crane models, quantities and location combinations that meet the requirements based on the relevant information of the construction site through actual lifting capacity analysis and site coverage inspection, and optimizes the preset objective function to obtain a temporary facility layout plan, and optimizes the temporary facility layout plan according to the preset multi-dimensional evaluation plan to determine the final layout plan. Among them, the multi-dimensional evaluation plan includes site dispersion evaluation, tower crane utilization evaluation and green construction evaluation, which effectively evaluates different layout plans during the layout optimization process to improve the synergy between tower cranes and other temporary facilities.

[0004] Another Chinese patent publication number CN117455065A is a multi-dimensional quantitative evaluation method and system for the plane layout of construction sites. It conducts traffic rationality evaluation, construction safety evaluation, construction economy evaluation, construction efficiency evaluation and environmental friendliness evaluation, including quantitative evaluation indicators such as traffic convenience between temporary facilities and temporary facility layout and maintenance rate, to solve the quantitative evaluation of the plane layout of construction sites and ensure the cost, safety and progress of construction.

[0005] However, the existing technology for the control of temporary facilities for construction still has significant limitations, which are as follows: the existing technology focuses on the initial layout planning of temporary facilities, and often simply determines the approximate location and scale of temporary facilities based on limited factors such as the basic geographical information of the construction site and the preliminary planning blueprint of the construction project, but lacks consideration of dynamic changing factors in the actual construction process. For example, the details of personnel flow in the temporary office area at each construction stage have not been deeply explored, making it difficult to determine whether the space scale can meet office needs and whether there are resource waste or congestion problems. The road load capacity under different transportation requirements at each construction stage of the temporary road has not been deeply considered, and the overload damage cannot be detected in time, which increases maintenance costs and safety risks. The actual consumption rate of construction materials and the dynamic utilization and suitability of space resources in the temporary material storage area have not been deeply analyzed, which can easily lead to a backlog of materials resulting in insufficient space or a poor storage environment, increasing the construction cost and time cost burden. Summary of the invention

[0006] In order to overcome the shortcomings of the background technology, an embodiment of the present invention provides an Internet-based construction temporary facility index early warning and control system, which can effectively solve the problems involved in the above-mentioned background technology.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0023] Reference Figure 1 As shown, the present invention provides an Internet-based construction temporary facility indicator early warning control system, including: a construction site layout division module, a personnel flow status analysis module, a road use status analysis module, a material consumption status analysis module and a temporary facility hidden danger early warning module.

[0024] The construction site layout division module is respectively connected to the personnel flow status analysis module, the road use status analysis module, and the material consumption status analysis module, and the personnel flow status analysis module, the road use status analysis module, and the material consumption status analysis module are all connected to the temporary facility hidden danger warning module.

[0025] The construction site layout division module is used to collect the overall layout map of the current construction stage of the target construction site through aerial photography by a drone equipped with a three-dimensional laser scanner, and divide it into a core construction area, a temporary office area, a temporary material storage area and a temporary road network.

[0026] The personnel flow status analysis module is used to analyze the personnel flow status during the initial monitoring period of the current construction phase of the target construction site, and evaluate the spatial efficiency adaptability of the temporary office area of ​​the target construction site to the current construction phase.

[0027] Reference Figure 2As shown, specifically, the evaluation of the spatial efficiency adaptability of the temporary office area of ​​the target construction site for the current construction stage includes: collecting aerial videos of the target construction site at each day and each monitoring period within the initial monitoring period of the current construction stage, determining the activity trajectories of each office worker in the temporary office area at each day and each monitoring period within the initial monitoring period of the current construction stage and the operation trajectories of each construction equipment in the core construction area, and analyzing the space utilization coefficient of the temporary office area during the initial monitoring period of the current construction stage. and site safety factor .

[0028] By formula Evaluate the spatial efficiency adaptability of the temporary office area of ​​the target construction site to the current construction stage, including is a natural constant, Preset reasonable reference space utilization coefficient and reasonable deviation space utilization coefficient for temporary office area. Pre-set site safety factor thresholds for temporary office areas.

[0029] Specifically, the The specific analysis process includes: planning the activity trajectory sub-areas of each office worker in the temporary office area during each day and each monitoring period during the initial monitoring cycle of the current construction phase.

[0030] Reference Figure 3 As shown, it should be noted that the planning of the above-mentioned activity track sub-area specifically refers to the convex hull algorithm, and its process is: construct an image coordinate system to obtain the position coordinates of each unit point on the activity track, take the unit point with the smallest position coordinate on the activity track as the reference point, calculate the polar angles of the remaining unit points on the activity track relative to the reference point through the inverse tangent function, sort the remaining unit points on the activity track in order from small to large polar angles, create a stack, push the reference point and the first unit point in the sorting into the stack, start traversing from the second unit point in the sorting, and for each subsequent unit point, retrieve the direction of the vector formed by it and the top of the stack. If the direction is left, push it into the stack. If the direction is right, pop the top element of the stack and recheck the direction of the vector formed by it and the new top of the stack. Repeat the operation until the direction becomes left or there is only one unit point left in the stack, and push it to the top of the stack. When the remaining unit points on the activity track are all traversed, the remaining unit points in the stack are the vertices of the convex hull, which are outlined in the order of the stack to obtain the complete outline of the convex hull, and the convex hull is used as the activity track sub-area.

[0031] According to the preset location scope of each functional zone of the temporary office area of ​​the target construction site and its preset permitted number of office workers, the number of office workers in each functional zone of the temporary office area during the initial monitoring period of the current construction phase is sorted out, and the ratio analysis is performed with the preset permitted number of office workers in the corresponding functional zone to obtain the space utilization rate of each functional zone of the temporary office area during each day and each monitoring period during the initial monitoring period of the current construction phase, and obtain the average space utilization rate of each functional zone of the temporary office area during the initial monitoring period of the current construction phase And the growth rate of space utilization ,in It is the number of each functional area of ​​the temporary office area. , calculated by the space utilization model Analyze the space utilization of each functional area of ​​the temporary office area during the initial monitoring period of the current construction phase.

[0032] It should be noted that the above The calculation process is as follows: first, sum up the space utilization rates of each monitoring period of each day in the initial monitoring period of the current construction stage of each functional zone of the temporary office area, divide it by the number of monitoring periods per day, and get the average space utilization rate of each day in the initial monitoring period of the current construction stage of each functional zone of the temporary office area, and sum it up again, and divide it by the number of days in the initial monitoring period of the current construction stage, to get the average space utilization rate of each functional zone of the temporary office area in the initial monitoring period of the current construction stage.

[0033] The calculation process is to divide the difference between the average space utilization rate of each day in the initial monitoring period of the current construction phase of each functional zone of the temporary office area and its previous day by the average space utilization rate of the previous day, and obtain the growth rate of the average space utilization rate of each day in the initial monitoring period of the current construction phase of each functional zone of the temporary office area and its previous day, and sum them up, and divide them by the number of days in the initial monitoring period of the current construction phase to obtain the space utilization growth rate of each functional zone of the temporary office area in the initial monitoring period of the current construction phase.

[0034] The influence weights of the functional zones in the temporary office area are set, and the spatial utilization of the functional zones in the temporary office area in the initial monitoring period of the current construction stage and the product of their corresponding influence weights are accumulated to obtain the spatial utilization coefficient of the temporary office area in the initial monitoring period of the current construction stage.

[0035] Specifically, the The specific analysis process includes: planning the operation track sub-areas of each construction equipment in the core construction area during each day and each monitoring period during the initial monitoring cycle of the current construction phase and calculating the shortest distance between it and the temporary office area ,in is the number of each day in the initial monitoring cycle of the current construction phase, , is the number of each monitoring period, , It is the number of each construction equipment in the core construction area. .

[0036] It should be noted that the planning process of the above-mentioned running track sub-area may specifically refer to the planning process of the activity track sub-area, and the running track sub-area is a convex hull and presents a polygonal shape.

[0037] The process of obtaining the shortest distance between the operation trajectory sub-area of ​​each construction equipment in the core construction area and the temporary office area during each day and each monitoring period during the initial monitoring period of the above-mentioned current construction stage is as follows: construct an image coordinate system, use a fitting tool to obtain the straight line fitting equations of each side of the operation trajectory sub-area of ​​each construction equipment in the core construction area during each day and each monitoring period during the initial monitoring period of the current construction stage, traverse the distances from each point on the contour of the temporary office area to each side of the operation trajectory sub-area of ​​each construction equipment in the core construction area during each day and each monitoring period during the initial monitoring period of the current construction stage, select the shortest distance from the point to the straight line as the shortest distance between the operation trajectory sub-area of ​​each construction equipment in the core construction area during each day and each monitoring period during the initial monitoring period of the current construction stage and the temporary office area.

[0038] The safety distance thresholds of various construction equipment relative to the temporary office area preset according to the construction safety regulations , according to the formula Analyze the safety hazard rate of each construction equipment operation in the core construction area relative to the temporary office area during each day and each monitoring period during the initial monitoring period of the current construction stage, and obtain the average safety hazard rate of each construction equipment operation in the core construction area relative to the temporary office area during the initial monitoring period of the current construction stage And the growth rate of safety hazards , calculated by the safety hazard degree calculation model The safety hazard degree of each construction equipment operation in the core construction area during the initial monitoring period of the current construction stage relative to the temporary office area is analyzed, and the maximum safety hazard degree is screened for inverse calculation to obtain the site selection safety factor of the temporary office area during the initial monitoring period of the current construction stage.

[0039] It should be noted that the specific process of obtaining the average safety hazard rate and safety hazard growth rate of each construction equipment operation in the core construction area relative to the temporary office area during the initial monitoring period of the current construction stage is consistent with the process of obtaining the average space utilization rate and space utilization growth rate of each functional area in the temporary office area during the initial monitoring period of the current construction stage.

[0040] It should be noted that in order to prevent the denominator from being equal to 0 during the above inversion operation, a preset constant needs to be set and added to the maximum safety hazard degree before the inversion operation is performed.

[0041] The embodiment of the present invention analyzes the space utilization coefficient and site safety factor of the temporary office area in the initial monitoring period of the current construction phase, and evaluates the spatial efficiency adaptability of the temporary office area of ​​the target construction site to the current construction phase. This not only helps to accurately grasp the actual utilization efficiency of the temporary office space, and provides valuable data support for optimizing the layout and area planning of the office area, but also fully considers the relative safety risks between the geographical location of the temporary office area and the operation of construction equipment in the core construction area, greatly improving the safety and stability of the temporary office area during the current construction phase.

[0042] The road usage analysis module is used to analyze the road usage status within the initial monitoring period of the current construction phase of the target construction site, and evaluate the comprehensive working condition adaptability of the temporary road network constructed at the target construction site to the current construction phase.

[0043] Specifically, the evaluation of the adaptability of the temporary road network of the target construction site to the comprehensive working conditions of the current construction stage includes: analyzing the accessibility index of the temporary road network of the target construction site according to the transportation location points and the size and width of various types of transportation vehicles planned in the construction vehicle transportation route ledger during the initial monitoring period of the current construction stage of the target construction site. .

[0044] The settlement displacement of each section of the temporary road network built at the target construction site in each monitoring period on each day during the initial monitoring period of the current construction phase is obtained through a three-dimensional laser scanner. The settlement displacement greater than the preset reasonable settlement displacement deviation threshold of the road monitoring is regarded as an abnormal settlement phenomenon. The number of the running vehicle in the aerial video during the monitoring period corresponding to the abnormal settlement phenomenon is identified to retrieve the load weight of the running vehicle, and the load weight of the running vehicle corresponding to the abnormal settlement phenomenon on each day during the initial monitoring period of the current construction phase of each section of the temporary road network built at the target construction site is obtained, and then the bearing capacity index of the temporary road network built at the target construction site is analyzed. .

[0045] It should be noted that the basis for the above-mentioned identification of abnormal settlement phenomena corresponding to the operating vehicle number in the aerial video during the monitoring period to retrieve the operating vehicle load weight is that before the transport vehicle performs each transport task, the professional staff of the target construction site will accurately enter the transport departure time point, the operating vehicle number and its corresponding load weight information for each transport task into the system. The operating vehicle number identified at the specific video frame monitoring time point in the aerial video is used to find the load weight information of the transport vehicle performing the transport task at the most recent transport departure time point before the video frame monitoring time point.

[0046] According to the accessibility index and bearing index of the temporary road network built at the target construction site, the formula Evaluate the adaptability of the temporary road network built at the target construction site to the comprehensive working conditions of the current construction stage, including They are respectively the preset accessibility index reaching standard threshold and the preset bearing capacity index reaching standard threshold of the temporary road network.

[0047] Specifically, the The specific analysis process includes: obtaining the number of reachable paths from the entrance location point of the temporary construction road network to each transportation location point; if the number of reachable paths from the entrance location point to any transportation location point is 0, the accessibility index of the temporary construction road network of the target construction site is set to 0.

[0048] If the number of reachable paths from the entrance location point to any transport location point is greater than or equal to 1, the monitoring width, monitoring flatness and monitoring slope of each road section in each reachable path from the entrance location point to each transport location point are obtained, and the number of passable vehicle types in each reachable path from the entrance location point to each transport location point of the temporary road network is analyzed. The ratio of the number of passable vehicle types to the total number of transport vehicle types is taken as the reachable vehicle number ratio, and the reachable vehicle number ratios of each reachable path from the entrance location point of the temporary road network to each transport location point are accumulated to obtain the accessibility index from the entrance location point of the temporary road network to each transport location point, and the minimum value is selected as the accessibility index of the temporary road network of the target construction site.

[0049] It should be noted that the specific analysis process of the number of passable vehicle types in each reachable path from the entrance point of the temporary road network to each transport location point is as follows: compare the monitored width of each reachable path from the entrance point of the temporary road network to each transport location point with the size width of each type of transport vehicle; if the size width of a certain type of transport vehicle is smaller than the monitored width of a certain reachable path from the entrance point of the temporary road network to a certain transport location point, and the absolute difference between the size width of this type of transport vehicle and the monitored width of the reachable path from the entrance point of the temporary road network to the transport location point is greater than or equal to the preset vehicle road traffic safety reserved width threshold, then this type of transport vehicle can be used as the basic passable vehicle type for the reachable path from the entrance point of the temporary road network to the transport location point. In this way, various types of basic passing vehicles in each accessible path from the entrance location point to each transport location point are screened, and the travel difficulty of each section in each accessible path from the entrance location point to each transport location point is analyzed according to the monitored flatness and monitored slope of each section in each accessible path from the entrance location point to each transport location point. Combined with the reasonable travel difficulty threshold of each type of basic passing vehicle preset section, if the travel difficulty of each section in a certain accessible path from the entrance location point to a certain transport location point is less than or equal to the reasonable travel difficulty threshold of a certain type of basic passing vehicle preset section, then this type of basic passing vehicle is used as the passable vehicle type in the accessible path from the entrance location point to the transport location point, and thus the number of passable vehicle types in each reachable path from the entrance location point to each transport location point of the temporary road network is counted.

[0050] It should be noted that the specific analysis process of the difficulty of travel of each section in each accessible path from the above-mentioned entrance location point to each transport location point is as follows: the monitored flatness of the section is used as the numerator and the preset benchmark flatness is used as the denominator to calculate the ratio; the monitored slope of the section is used as the denominator and the preset benchmark slope is used as the numerator to calculate the ratio; the two ratio calculation results are multiplied to obtain the difficulty of travel of the section, thereby obtaining the difficulty of travel of each section in each accessible path from the entrance location point to each transport location point.

[0051] Specifically, the The specific analysis process includes: extracting the minimum operating vehicle load weight corresponding to the abnormal settlement phenomenon in each section of the temporary road network of the target construction site during the initial monitoring period of the current construction phase on each day , the difference in vehicle load weight corresponding to the last abnormal settlement phenomenon and the first abnormal settlement phenomenon , calculate the bearing capacity of the temporary road network of the target construction site on each day during the initial monitoring period of the current construction phase , , The load-bearing threshold of the road can be preset for the temporary road network planning of the target construction site, which is calculated by the formula Obtain the bearing capacity index of the temporary road network of the target construction site, is the number of days of the initial monitoring cycle in the current construction phase, Temporary construction of road network for target construction sites during the initial monitoring period of the current construction phase The carrying capacity of the sky.

[0052] The embodiment of the present invention analyzes the accessibility index and bearing capacity index of the temporary road network constructed at the target construction site, evaluates the adaptability of the temporary road network constructed at the target construction site to the comprehensive working conditions of the current construction stage, accurately measures the ability of the road to cope with vehicle traffic and vehicle load at the current construction stage, and enhances the reliability and adaptability of the road infrastructure during the construction process.

[0053] The material consumption status analysis module is used to analyze the material consumption status of the target construction site during the initial monitoring period of the current construction phase, and evaluate the spatial resource adaptability of the temporary material storage area of ​​the target construction site to the current construction phase.

[0054] Specifically, the evaluation of the spatial resource adaptability of the temporary material storage area of ​​the target construction site for the current construction stage includes: dividing the initial monitoring period into monitoring intervals according to a preset number of days, obtaining the initial inventory, final inventory and consumption of various types of construction materials in the temporary material storage area of ​​the target construction site in each monitoring interval of the current construction stage through the inventory count log, and calculating the inventory turnover rate of various types of construction materials in the temporary material storage area of ​​the target construction site in each monitoring interval of the current construction stage. , is the number of each monitoring interval in the current construction phase, , The numbers of various construction materials. , combined with the preset reasonable inventory turnover rate range of various construction materials, evaluate the accumulation risk level of various construction materials in the temporary material storage area of ​​the target construction site during the initial monitoring period of the current construction phase , in order to analyze the storage capacity adaptability of the temporary material storage area of ​​the target construction site for the current construction stage.

[0055] It should be noted that the above inventory turnover rate is the ratio of consumption to average inventory, where the average inventory is half of the sum of the beginning inventory and the ending inventory.

[0056] The specific analysis process of the storage capacity adaptability of the temporary material storage area of ​​the above-mentioned target construction site for the current construction stage is as follows: retrieve the free storage volume of various construction material storage sub-areas in the temporary material storage area of ​​the target construction site at the end time of the initial monitoring period of the current construction stage, and multiply it by the degree of risk of accumulation that can be coped with by the preset unit storage volume, so as to obtain the degree of risk of accumulation that can be coped with by various construction material storage sub-areas in the temporary material storage area of ​​the target construction site at the end time of the initial monitoring period of the current construction stage. , and then by the formula Obtain the storage capacity adaptability of the temporary material storage area of ​​the target construction site for the current construction phase.

[0057] Collect the monitored temperature values, humidity values ​​and light intensity values ​​of various types of construction material storage sub-areas in the temporary material storage area of ​​the target construction site on each day during the initial monitoring period of the current construction stage; calculate the temperature adaptation ratio, humidity adaptation ratio and light intensity adaptation ratio of various types of construction material storage sub-areas in the temporary material storage area of ​​the target construction site on each day during the initial monitoring period of the current construction stage according to the reasonable temperature range, reasonable humidity range and reasonable light intensity range of the preset storage environment of various types of construction materials; multiply the temperature adaptation ratio, humidity adaptation ratio and light intensity adaptation ratio to obtain the temperature adaptation ratio, humidity adaptation ratio and light intensity adaptation ratio of each type of construction material storage sub-area in the initial monitoring period of the current construction stage. Calculate the basic environmental adaptation index of various construction material storage sub-areas in the temporary material storage area of ​​the target construction site within the initial monitoring period of the current construction stage, screen the minimum basic environmental adaptation index of various construction material storage sub-areas in the temporary material storage area of ​​the target construction site within the initial monitoring period of the current construction stage, set the corresponding important weights of various construction materials, and accumulate the product of the minimum basic environmental adaptation index of various construction material storage sub-areas in the temporary material storage area of ​​the target construction site within the initial monitoring period of the current construction stage and the corresponding important weights to obtain the storage environment adaptability of the temporary material storage area of ​​the target construction site for the current construction stage.

[0058] It should be noted that the specific calculation process of the temperature adaptation ratio of various types of construction material storage sub-areas in the temporary material storage area of ​​the target construction site on each day during the initial monitoring period of the above-mentioned current construction stage is as follows: if the monitored temperature value of a certain type of construction material storage sub-area is within the reasonable temperature range of its preset storage environment, the temperature adaptation ratio of the storage sub-area of ​​this type of construction material is set to 1; if the monitored temperature value of a certain type of construction material storage sub-area is outside the reasonable temperature range of its preset storage environment and is greater than the upper limit value, the absolute difference between the upper limit value of the reasonable temperature range of the preset storage environment of this type of construction material and the monitored temperature value of the storage sub-area is further analyzed with the upper limit value of the reasonable temperature range of the preset storage environment of this type of construction material; The value analysis result is substituted into the exponential function with e as the base, and the temperature adaptation ratio of the storage sub-area of ​​this type of construction materials is output. If the monitored temperature value of a certain type of construction material storage sub-area is outside the reasonable temperature range of its preset storage environment and is less than the lower limit value, then the difference between the lower limit value of the reasonable temperature range of the preset storage environment of this type of construction materials and the monitored temperature value of the storage sub-area is further analyzed with the lower limit value of the reasonable temperature range of the preset storage environment of this type of construction materials. The ratio analysis result is substituted into the exponential function with e as the base, and the temperature adaptation ratio of the storage sub-area of ​​this type of construction materials is output. In summary, the temperature adaptation ratios of various types of construction material storage sub-areas in the temporary material storage area of ​​the target construction site on each day within the initial monitoring period of the current construction stage are obtained.

[0059] Similarly, the humidity adaptation ratio and light intensity adaptation ratio of each type of construction material storage sub-area in the temporary material storage area of ​​the target construction site on each day during the initial monitoring period of the current construction stage are obtained.

[0060] The storage capacity adaptability and storage environment adaptability of the temporary material storage area of ​​the target construction site for the current construction stage are compared with the preset storage capacity adaptability threshold and storage environment adaptability threshold of the temporary material storage area, respectively, to evaluate the spatial resource adaptability of the temporary material storage area of ​​the target construction site for the current construction stage.

[0061] It should be noted that the evaluation formula for the spatial resource adaptability of the temporary material storage area of ​​the above-mentioned target construction site for the current construction stage can specifically refer to the evaluation formula for the comprehensive working condition adaptability of the temporary road network constructed at the target construction site for the current construction stage.

[0062] Specifically, the ,in For the The lower limit of the reasonable inventory turnover rate range of pre-placed construction materials, The first Minimum inventory turnover rate for construction materials, is the number of monitoring intervals in the current construction phase, The current construction phase The target construction site temporary material storage area is the first Inventory turnover rate of construction materials.

[0063] It should be noted that the calculation formula for the risk level of accumulation of various types of construction materials in the temporary material storage area of ​​the target construction site during the initial monitoring period of the current construction stage is based on the following: if the inventory turnover rate of construction materials is less than the lower limit of the preset reasonable inventory turnover rate range, it means that there is a potential for accumulation of construction materials. If the inventory turnover rate of construction materials during the initial monitoring period of the current construction stage generally shows a downward trend, it means that there is a potential for accumulation of construction materials.
