[0050] like Figures 1 to 3 As shown, the present invention provides a method for regulating carbon emissions from construction materials and transportation, comprising the following steps:

[0051] S1: Acquire material data, quantity data, and transportation data during the monitoring period during the construction process; transportation data includes: transportation method and transportation distance;

[0052] S2: Obtain a large amount of engineering carbon emission data to build a carbon emission model, and input material data, usage data, and transportation data into the carbon emission model to obtain carbon emission data; the carbon emission data includes: building material carbon emissions and transportation carbon emissions;

[0053] S3: Determine whether there are any anomalies in the carbon emission data; if so, send a reminder to the administrator and transmit a visual monitoring report generated based on the carbon emission data.

[0054] The working principle of the above technical solution: During the construction process, in order to reduce damage to the environment, it is necessary to measure the carbon emissions of the construction project to avoid excessive carbon emissions; and the existing carbon emission measurement method generally relies on annual or quarterly energy consumption data and emission factors for calculation, which makes the calculation results have obvious lags, making the data on carbon emissions less timely, difficult to achieve real-time, and separated from the actual progress of the project, making it difficult to supervise in time; so a construction project is divided into several construction contents according to the construction sequence, and each construction content can be decomposed into multiple identical construction contents, and each item and each construction content is numbered to obtain the number information of each construction content; then the monitoring time is determined according to the standard time specified for each construction content, and the monitoring time is monitored. Equal sampling is performed to obtain the material data, usage data and transportation data of various materials used in the construction process; among them, the material data is the type of material used, such as steel bars, cement, etc.; the usage data is the amount of each material consumed, such as 50 bags of cement, etc.; the transportation data is the method of transporting materials, and the transportation data includes the transportation method and transportation distance. For example, cement is transported from a cement plant 20km (transportation distance) by a small truck (transportation method); the material data, usage data and transportation data are then output to the carbon emission model for calculation to calculate the carbon emission data caused by the materials within the preset time period, namely the carbon emissions of building materials and transportation carbon emissions; then determine whether there is any abnormality in the carbon emission data; if so, send a reminder to the administrator, and transmit a visual monitoring report generated based on the carbon emission data;

[0055] The beneficial effects of the above technical solution: Through the above technical solution, the carbon emissions generated during this period are determined by obtaining the amount of materials consumed during the period, so as to realize real-time monitoring of carbon emissions in the construction process during the project, and facilitate the control and adjustment of subsequent construction methods according to the carbon emissions; at the same time, during the construction process, the carbon emission model is used to realize the simultaneous statistics of carbon emissions from material consumption and transportation, realize integrated supervision, and facilitate systematic centralized management.

[0056] In one embodiment, a large amount of engineering carbon emission data is obtained to build a carbon emission model, including:

[0057] S21: Obtain a large amount of engineering carbon emission data and the types and scales of construction projects;

[0058] S22: Cluster and filter the project carbon emission data according to the project type and project scale of the construction project to obtain the carbon emission data of the target project;

[0059] S23: Retrieve and obtain calculation-related information for the target project's carbon emission data; the calculation-related information includes: material data, carbon emission factors, and carbon emission calculation methods;

[0060] S24: clustering the material data, and combining the carbon emission factors and carbon emission calculation methods that appear most frequently with the corresponding material data to obtain a combination of material data-carbon emission factors and carbon emission calculation methods;

[0061] S25: Construct a carbon emission model based on the combination of material data, carbon emission factors and carbon emission calculation methods;

[0062] The working principle of the above technical solution: in the process of carbon emission measurement, when calculating the carbon emissions of materials (hidden carbon emissions), it is necessary to calculate the carbon emissions generated from the production of materials and the carbon emissions generated during the construction and use process together. However, due to the differences in the equipment used in different types and scales of construction projects, the carbon emissions generated under the same consumption will be different. For example, in large-scale projects, a large mixer is used to mix a certain amount of cement, while a small mixer or manual mixing is used to mix the same amount of cement in small-scale projects. The time spans of the two are different, and the different equipment used leads to different carbon emissions, so the calculation method of carbon emissions will also be different; the construction carbon emission data of similar projects are clustered and screened in the database based on the project scale and project type of the current construction project. Since the type and scale of the construction projects are similar, the specifications and types of the equipment used in the construction process are also similar, resulting in similar carbon emission accounting methods for the two. After the clustering and screening is completed, The carbon emission data of the target project is obtained; then the calculation-related information in the carbon emission data of the target project is retrieved, and the material data, carbon emission factor and carbon emission calculation method in any target project carbon emission data are retrieved; then the carbon emission data of the target project are clustered by the material data, and the carbon emission factor and carbon emission calculation method that appear the most times are combined with the corresponding material data to obtain a combination of material data-carbon emission factor and carbon emission calculation method; specifically, each material corresponds to a calculation method for carbon emissions generated by production, a calculation method for carbon emissions generated during use, a calculation method for carbon emissions generated by transportation and a carbon emission factor, and this calculation method is combined with the material type (material data) to obtain a combination of material data-carbon emission factor and carbon emission calculation method; then a carbon emission model is constructed based on the above combination, and trained until convergence using the carbon emission data of the target project; finally, the collected material data, usage data and transportation data are input into the model for solution, thereby obtaining the corresponding carbon emission data;

[0063] The beneficial effects of the above technical solution: Through the above technical solution, by screening the project scale and project type of construction projects, taking into account the differences in carbon emissions during the construction process, the carbon emissions of construction projects can be more comprehensively reflected, and the most suitable carbon emission calculation method can be found for each project type, avoiding the errors caused by the use of a unified accounting method and improving the accuracy of carbon emission calculations; at the same time, through more accurate carbon emission accounting results, construction project managers can better formulate carbon emission reduction strategies.

[0064] In one embodiment, a visual monitoring report is generated based on carbon emissions data, including:

[0065] The usage data, transportation data, building material carbon emissions, and transportation carbon emissions corresponding to any material data are mapped one by one and a table is generated to obtain a visual monitoring report;

[0066] The working principle of the above technical solution is as follows: When calculating carbon emissions through the carbon emission model, the material data and the corresponding usage data and transportation data are input into the model. The model then calculates the carbon emissions of building materials (carbon emissions generated during production and use) and transportation carbon emissions based on the combination, and then tabulates these data to obtain a visual monitoring report;

[0067] Beneficial effects of the above technical solution: Through the above technical solution, managers can understand the carbon emission accounting results of each material through visual monitoring reports, which is convenient for optimizing and adjusting the subsequent material usage strategy and better formulating carbon emission reduction strategies.

[0068] In one embodiment, it is determined whether there is any anomaly in the carbon emission data; if so, an alert is sent to the administrator, and a visual monitoring report generated based on the carbon emission data is transmitted, including:

[0069] S31: Obtain carbon emission data for a number of construction contents, mark any construction content as a target construction content, and monitor carbon emission data for any construction content of any target construction content;

[0070] S32: Obtain a construction carbon emission change graph of the carbon emission data of the target construction content during the monitoring time; wherein each construction content of each item corresponds to a construction carbon emission change graph, and the sampling time and carbon emission data during the monitoring time are used as the horizontal axis and vertical axis of the construction carbon emission change graph respectively;

[0071] S33: Using a preset statistical method, determine whether there is any anomaly in the carbon emission data in the construction carbon emission change graph; if so, issue a reminder to the administrator and generate a visual monitoring report based on the carbon emission data corresponding to the target construction content;

[0072] S34: Obtaining a second construction carbon emission change graph of carbon emission data for each construction content within the monitoring time;

[0073] S35: Determine whether there is any abnormal second construction carbon emission change graph among all second construction carbon emission change graphs; if so, issue a reminder to the administrator and generate a visual monitoring report based on the carbon emission data corresponding to the abnormal construction content;

[0074] Determining whether there is any abnormal second construction carbon emission change graph among all second construction carbon emission change graphs includes:

[0075] S351: Obtain data corresponding to the continuous sampling time of each second construction carbon emission change graph during the monitoring period as comparison points, generate several comparison matrices; and sort the elements in each comparison matrix according to the construction content number information;

[0076] S352: Calculate the fluctuation value between adjacent comparison points in each comparison matrix. The calculation formula is as follows:

[0077]

[0078] Among them, C m,n is the fluctuation value of the nth comparison point in the mth comparison matrix, j is the number of comparison points in the mth comparison matrix, D m,n+1 is the carbon emission data of the n+1th comparison point in the mth comparison matrix, D m,n is the carbon emission data of the nth comparison point in the mth comparison matrix, and exp is the exponential function with e as the base;

[0079] S353: Determine whether the difference value of the comparison point is greater than a preset error threshold; if so, determine that the comparison point is an abnormal point;

[0080] S354: Determine the number of outliers in each comparison and calculate the outlier coefficient of each comparison matrix. The calculation formula is as follows:

[0081]

[0082] Among them, λ m is the abnormal coefficient of the mth comparison matrix, S m is the number of abnormal points in the m-th comparison matrix, j is the total number of comparison points in the m-th comparison matrix;

[0083] S355: Calculate the mutation value of each abnormal point. The calculation formula is as follows:

[0084] ξ m,x =(1-λ m )*C m,x

[0085] Among them, ξ m,x is the mutation value of the xth abnormal point in the mth comparison matrix, C m,x is the difference value of the xth abnormal point in the mth comparison matrix, x∈[1,S m ], and x is an integer;

[0086] S356: Calculate the abnormal value of the second construction carbon emission change graph; wherein the calculation formula is:

[0087]

[0088] Among them, H a is the abnormal value of the a-th second construction carbon emission change graph, B is the total number of comparison matrices corresponding to the comparison points in the a-th second construction carbon emission change graph, ξ a,m is the mutation value of the abnormal point corresponding to the mth comparison matrix in the ath second construction carbon emission change graph;

[0089] S357: Determine whether any abnormal value of the second construction carbon emission change graph is greater than a preset abnormal threshold; if so, determine that the second construction carbon emission change graph is abnormal;

[0090] The working principle of the above technical solution: In the actual construction process, since the construction content of each section of the building project is different, the carbon emissions generated in the same time will change with the progress of the construction project, making it difficult to judge whether there is an abnormality in the carbon emissions at each monitoring time; in order to better control the carbon emissions of the entire project, by obtaining the carbon emission data of several construction contents, any construction content is marked as the target construction content, and the carbon emission data of any construction content of any target construction content is monitored; for example, in the piling process of a building, multiple pile foundations will be constructed simultaneously, but due to quantity restrictions, the construction order of the pile foundations will be different, that is, piling is one construction content, The construction of a pile foundation is one of the construction contents of one item; then a construction carbon emission change graph of the carbon emission data of the target construction content within the monitoring time is obtained; wherein, each construction content of each item corresponds to a construction carbon emission change graph, and the sampling time and carbon emission data within the monitoring time are used as the horizontal and vertical coordinates of the construction carbon emission change graph respectively; through the preset statistical method, it is judged whether there is an abnormality in the carbon emission data in the construction carbon emission change graph; if so, a reminder is issued to the administrator, and a visual monitoring report is generated based on the carbon emission data corresponding to the target construction content; wherein, the preset statistical methods include summation, etc., to obtain the carbon emission data of any construction content in any item within the monitoring time. The carbon emission is judged to be greater than the preset value; at the same time, cross-carbon emission monitoring will be carried out on the construction content of the same project. Specifically, a second construction carbon emission change graph of the carbon emission data of each construction content within the monitoring time is obtained; wherein, the second construction carbon emission change graph is obtained by obtaining the progress of any completed construction of any item as the monitoring time, and then using the sampling time and carbon emission data within the monitoring time as the horizontal axis and vertical axis respectively; then, through the carbon emission difference of any construction content at the same construction time, it is judged whether there is any abnormal second construction carbon emission change graph in all the second construction carbon emission change graphs; specifically, each second construction carbon emission change graph is obtained. The data corresponding to the continuous sampling time of the graph during the monitoring time are used as comparison points to generate several comparison matrices; the elements in each comparison matrix are sorted according to the construction content number information; the fluctuation value between adjacent comparison points in each comparison matrix is ​​then calculated; it is then determined whether the difference value of the comparison point is greater than the preset error threshold; if so, the comparison point is determined to be an abnormal point; the number of abnormal points in each comparison is determined, and the abnormal coefficient of each comparison matrix is ​​calculated; the mutation value of each abnormal point and the abnormal value of the second construction carbon emission change graph are calculated; finally, it is determined whether any abnormal value of the second construction carbon emission change graph is greater than the preset abnormal threshold; if so, the second construction carbon emission change graph is determined to be abnormal;When there are abnormalities in carbon emission data, an alert will be sent to the administrator, and a visual monitoring report will be generated based on the carbon emission data corresponding to the abnormal construction content;

[0091] The beneficial effects of the above technical solution: Through the above technical solution, by monitoring the differences between each construction content in the same construction content, timely reporting to the administrator when an abnormality occurs, making separate adjustments to the construction content, and adjusting the construction method in real time according to the construction progress, avoiding carbon emissions exceeding the standard, achieving precise control of carbon emissions, and reducing carbon emissions exceeding the standard due to problems encountered by workers during the construction process; at the same time, monitoring of individual construction contents ensures that the carbon emissions of a single construction content are qualified, providing accuracy in carbon emission control.

[0092] In one embodiment, if the carbon emission data is not greater than a preset carbon emission value, the material data, the usage data, and the transportation data are re-obtained after a preset time for determination;

[0093] The working principle and beneficial effects of the above technical solution are as follows: by periodically obtaining material data, usage data and transportation data for judgment, the control of carbon emissions is consistent with the actual progress of the project.

[0094] like Figure 3 As shown, the present invention also provides a carbon emission monitoring system for construction materials and transportation, comprising:

[0095] The data acquisition module is used to obtain the material data, usage data and transportation data during the monitoring period of the construction process;

[0097] The carbon emission monitoring module is used to determine whether there are any anomalies in the carbon emission data; if so, it will send a reminder to the administrator and transmit a visual monitoring report generated based on the carbon emission data.

[0098] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
