[0047] S4: The energy consumption assessment of the construction stage, the energy consumption forecast of the construction stage and the process optimization information are made into a construction energy consumption log and saved to the server.

[0048] It should be noted that before the start of road construction, the construction unit will conduct energy consumption assessment on each construction link according to the construction project, and obtain the energy consumption assessment of the construction link. During the construction process, the construction unit will track and manage the energy consumption data of the construction according to the energy consumption assessment of the construction link, and implement energy conservation and emission reduction work. The construction process set is expressed as: , where a represents the priority of the construction link, a=1,2,3...,a, the smaller the number of the construction link priority, the higher the priority. Indicates that the construction link priority is a and the process start time is construction process.

[0049] Specifically, step S2 includes the following steps:

[0050] S201: Obtain a time node set from the preset time nodes, where the time node set is expressed as: , where T represents the time node set, m and n represent the node numbers of the time nodes, and m <n;

[0051] S202: Acquire historical construction information of the current construction phase, wherein the historical construction information includes a historical construction energy consumption set and a historical construction quantity set, wherein the historical construction energy consumption set is expressed as: , where Q represents the historical energy consumption of construction equipment, Indicates at time node The historical construction energy consumption is expressed as: , where W represents the historical construction volume set, Indicates at time node Historical construction volume;

[0052] S203: construct an energy consumption prediction model based on the historical construction energy consumption set, and obtain the construction energy consumption prediction according to the planned construction volume through the energy consumption prediction model. The energy consumption prediction model is expressed as: , where EY represents the predicted construction energy consumption, and represents the parameter factor, Indicates time node The planned construction volume, the construction energy consumption forecast represents the time node The predicted amount of construction energy consumption is processed by the least square method to obtain the parameter factor;

[0053] S204: Obtain the predicted energy consumption of the construction link according to the predicted construction energy consumption and the historical construction energy consumption.

[0054] Specifically, the specific calculation method of the predicted energy consumption of the construction link is: according to the historical construction energy consumption set, the total historical construction energy consumption is obtained, and the total historical construction energy consumption is expressed as: ,in, Indicates time node The total historical construction energy consumption, Indicates at time node The historical construction energy consumption is calculated based on the total historical construction energy consumption and the predicted construction energy consumption. The predicted energy consumption of the construction link is calculated, where: It represents the predicted energy consumption of the construction link, and EY represents the predicted construction energy consumption.

[0055] It should be further explained that the construction energy consumption is collected according to the preset time nodes, and the energy consumption forecast of the construction link is predicted according to the construction energy consumption. The preset time nodes are evenly divided according to the construction period of the construction link. In this embodiment, the historical construction information obtained refers to the time nodes in the current construction link. The historical construction energy consumption set and the historical construction quantity set are obtained based on the historical construction energy consumption and the historical construction quantity collected at the historical time nodes, and the parameter factors are obtained by least squares processing based on the historical construction energy consumption and the historical construction quantity. The parameter factors obtained through the historical construction information are used to predict the construction energy consumption prediction, thereby realizing the real-time prediction of the energy consumption of the construction link, which is beneficial for the construction unit to timely track, manage and adjust the energy consumption during the construction process;

[0056] For example, a time node set is set for the construction phase. The time node set has , based on the time node set, collect the time nodes The historical construction energy consumption set is: Q = {22, 27, 42, 32}, and the corresponding historical construction volume set is: W = {4, 5, 8, 6}. The time node needs to be predicted The predicted construction energy consumption, corresponding to the time node The corresponding planned construction volumes are {3, 7, 12, 9, 6}, and the energy consumption prediction model is: , α and β in the model are obtained by processing the historical energy consumption set and the historical construction volume set by the least squares method, where α=2, β=5, then the time node The predicted energy consumption of construction = 2×5+5×3+5×7+5×12+5×9+5×6=195, then the predicted energy consumption of construction link = 22+27+42+32+195=318.

[0057] Specifically, step S3 includes the following steps:

[0058] S301: According to the predicted energy consumption of the construction stage and the assessed energy consumption of the construction stage, the formula The energy consumption difference is calculated, where Indicates the energy consumption difference, represents the energy consumption assessment of the construction process, Indicates the predicted energy consumption of the construction link;

[0059] S302: When the energy consumption difference is greater than or equal to a preset threshold, the energy consumption is abnormal, and energy consumption abnormality warning information is generated; when the energy consumption difference is less than the preset threshold, the energy consumption is normal;

[0060] S303: According to the abnormal energy consumption warning information, feature extraction is performed on the construction process in the construction process set to obtain a process feature vector, a process feature vector set is obtained based on the process feature vector, two process feature vector sets are randomly selected, and the process similarity of the two process feature vectors in the process feature vector set is calculated. The calculation formula is: ,in, Represents the process similarity, and represents the process feature vector, i and j represent the process start time, Represents the modular operation of vectors;

[0061] S304: When the process similarity is less than the preset threshold, it means that there is no conflict in the process. When the process similarity is greater than the preset threshold, it means that there is a conflict in the process. When there is a conflict in the process, the process start time is adjusted according to the priority of the construction link where the construction process is located to obtain process optimization information.

[0062] Specifically, according to the construction link priority of the construction process, adjusting the process start time specifically includes: obtaining the preset buffer time of the construction process, when there is a conflict between two construction processes, and the construction process and construction process Satisfy the conditions When the construction process starts, the process start time is adjusted according to the preset buffer time to obtain process optimization information, which is expressed as: , where v and z represent the priority of the construction link, i and j represent the start time of the process, and It indicates the conflicting construction procedures, and t indicates the preset buffer time.

[0063] It should be further explained that when the energy consumption difference between the predicted energy consumption of the construction link and the assessed energy consumption of the construction link is greater than or equal to the preset threshold, it indicates that there is an abnormality in the energy consumption of the construction link. In this embodiment, the construction process already includes the priority of the construction link and the start time of the process. During the road construction process, the construction process includes the spatial location information of the construction process. According to the priority of the construction link, the start time of the process and the spatial location information, it is judged whether there is a conflict in the construction process. If there is a conflict, the construction process of the construction link with a low priority is adjusted and optimized, thereby reducing the energy waste of waiting for the construction process. By adjusting and optimizing the construction process, the road construction efficiency is improved.

[0064] For example, in the embodiment of the above step S2, the predicted energy consumption of the construction link has been calculated. Based on this, since the energy consumption assessment of the construction link is 300, the energy consumption difference = |energy consumption assessment of the construction link - predicted energy consumption of the construction link| = 18. When the preset threshold is 10, if the energy consumption difference is greater than the preset threshold, it is judged that the energy consumption is abnormal, and an abnormal energy consumption warning information is generated;

[0065] According to the abnormal energy consumption warning information, the construction process in the construction process set is feature extracted to obtain the process feature vector, and the process feature vector set is obtained based on the process feature vector. The process feature vector set A and the process feature vector set B are randomly selected, and there are process feature vectors belonging to the process feature vector set A. , the process feature vector belonging to the process feature vector set B , according to the process characteristic vector and process feature vector By formula The process similarity is calculated. When the preset threshold is 0.80, the process similarity is greater than the preset threshold, then the process feature vector and process feature vector There are conflicts in the corresponding construction processes. By comparing the priorities of the construction links in which the two construction processes are located, the preset buffer time is added to the start time of the construction process with a low priority in the construction link, so as to obtain the process optimization information, solve the energy waste problem caused by cross-process conflicts, and make the construction links and construction processes smoother.

[0066] Furthermore, the present application also provides a calculation data management system based on road construction energy consumption assessment, including:

[0067] The data acquisition module is used to evaluate the energy consumption of the construction link in the road construction and obtain the energy consumption evaluation of the construction link; set the priority of the construction link according to the construction period and obtain the priority of the construction link; set the process start time for the construction process in the construction link and obtain the construction process set;

[0068] The energy consumption prediction module is used to obtain the construction period of the construction link, preset the time node according to the construction period, and set the planned construction volume according to the time node, collect the construction energy consumption and construction volume in real time according to the time node, and predict the total energy consumption of the construction link according to the construction energy consumption and the construction volume to obtain the predicted energy consumption of the construction link;

[0069] An energy consumption accounting module is used to optimize the construction process according to the energy consumption assessment amount of the construction link and the energy consumption forecast amount of the construction link, obtain process optimization information, and upload the process optimization information to the handheld terminal;

[0070] The data management module is used to generate the energy consumption assessment of the construction stage, the energy consumption forecast of the construction stage and the process optimization information into a construction energy consumption log and save it to the server.

[0071] Specifically, the specific calculation method of the predicted energy consumption in the construction process is as follows:

[0072] A time node set is obtained from a preset time node, and historical construction information of the current construction link is obtained based on the time node set, wherein the historical construction information includes a historical construction energy consumption set and a historical construction quantity set, and an energy consumption prediction model is constructed according to the historical construction energy consumption set. The planned construction quantity is processed by the energy consumption prediction model to obtain a construction energy consumption prediction;

[0073] The total historical construction energy consumption is obtained according to the historical construction energy consumption set, and the predicted energy consumption of the construction link is obtained by summing the total historical construction energy consumption and the predicted construction energy consumption.

[0074] Specifically, the specific calculation method of the process optimization information is as follows:

[0075] An energy consumption difference is obtained according to the predicted energy consumption of the construction link and the assessed energy consumption of the construction link. When the energy consumption difference is greater than or equal to a preset threshold, the energy consumption is abnormal, and abnormal energy consumption warning information is generated. When the energy consumption difference is less than the preset threshold, the energy consumption is normal.

[0076] According to the abnormal energy consumption warning information, feature extraction is performed on the construction process in the construction process set to obtain a process feature vector, a process feature vector set is obtained based on the process feature vector, two process feature vector sets are randomly selected, and the process similarity of the two process feature vectors in the process feature vector set is calculated;

[0077] When the process similarity is less than the preset threshold, it means that there is no conflict in the process. When the process similarity is greater than the preset threshold, it means that there is a conflict in the process. When there is a conflict in the process, the preset buffer time of the construction process is obtained, and the construction process with a low priority in the construction link is selected. The process start time of this construction process is added with the preset buffer time to obtain the process optimization information.
