When the daily average consumption of each material in the first sub-item is counted, the denominator is calculated specifically by counting the occurrence days of a certain material, all the daily average consumption of the material in the day is counted as a numerator, and the consumption of the material is obtained by the ratio of the two.

It will be appreciated that the cumulative amount of each material used in the first sub-item is specifically expressed as 1β j The cumulative usage of each material of the second sub-item is specifically expressed as 1 beta j The cement accumulation using amount of the first sub-item is specifically expressed as 1 beta Cement and its preparation method The respective material demand amounts Nmu of the first event in the first sub-item i1 Cement demand N mu for the first event in the first sub-item Cement 1 。
Specifically, the total amount of each material required by the event arranged in sequence with the first sub-item is gradually accumulated, and when the accumulated value of each material is greater than the accumulated usage amount of each material of the sub-item after a certain event is reached and the accumulated value of each material of the event before the event is less than or equal to the accumulated usage amount of each material of the sub-item, the event currently in progress with the first sub-item can be obtained.
Note that, nβ j Where j may replace the names of the materials to indicate the cumulative amount of use of a material, and j may refer to the use of a new device.
Further, the process of determining the current sub-project construction data based on the determined current processing event and comparing the consumption of each material on the same day with the consumption data of each material on the same day includes:
m1: determining the accumulated usage amount alpha of each material of engineering projects j J represents the substitute label of each material in the engineering project, and the difference K between the cumulative usage of each material in the engineering project and the cumulative usage of each material determined to be subjected to the event sub-project is calculated j ；
Specifically, the calculation formula is K j ＝α j -ε j ，K j For the current usage of each material of the event sub-item which is not performed, the event sub-item is determined to be epsilon j 。
M2: calculating the difference L between the consumption of each material on the same day and the consumption of each material on the same day of the determined event sub-project j ；
Specifically, the calculation formula is L j ＝θ j -σ j The consumption of each material is theta j It has been determined that the daily consumption of each material of the event sub-project is sigma j 。
M3: based on K j Analyzing which two groups of marked events the event currently performed by the next sub-item is specifically between;
specifically, after removing the sub-items for which the event has been determined to be performed, the respective amounts of material K currently used by the remaining sub-items are determined j Based on K j New material or new equipment is present in the sub-project, and the next sub-project can be directly determined between two sets of marking events.
M4: difference K based on cumulative usage of each material j And the difference L of the consumption of each material on the same day j Determining the current event of the next sub-item;
specifically, after determining which two marked events the next sub-item is between, which materials and L are used based on the events between the two sets of marked events, respectively j A currently ongoing event is determined.
Wherein the difference L of the consumption of each material on the same day j The type of the daily consumption material can be obtained, the specific consumption of each material is compared with the daily consumption of each material of the first sub-item, based on L j The type of material and the amount of consumption of the material to determine the event currently being performed.
It should be noted that, in the event between two adjacent marked events in the sub-item, the material type of each event is different.
M5: steps M1-M5 are repeated until all ongoing sub-items and events carried out by the sub-items are determined.
Further, the specific process of S6 includes:
setting expected completion time for the first execution sub-item based on the disassembled sub-items;
counting the consumption of each material and the daily average consumption of each material of the first execution sub-project, calculating the fluctuation value of each material consumption per day, setting a fluctuation threshold, and analyzing the reason or carrying out early warning if the fluctuation of the daily consumption of the material is larger than the fluctuation threshold;
specifically, the fluctuation threshold may be set to ±2%, i.e
-2% < (consumption value of a certain material on the day-average consumption value of the material)/average consumption value of the material 100% < 2%; and if the analysis and investigation cause is the waste of materials, the analysis and investigation cause is more than 2%, the engineering progress is accelerated, the cause of the engineering acceleration is determined, the engineering project efficiency is improved based on the cause, the early warning is carried out if the analysis and investigation cause is the waste of materials, and the analysis and investigation cause is less than 2%, and the early warning is carried out.
Calculating the completion time of the sub-project based on the daily average consumption of each material of the sub-project and the total material demand of each sub-project event arranged in time;
based on the actual completion time of the first sub-project, the completion time of the subsequent sub-project is predicted, and meanwhile, monitoring and early warning and time prediction are performed on the engineering project based on the consumption of each material of each sub-project every day.
Specifically, when the first sub-project is carried out, the subsequent sub-projects are carried out simultaneously, after the first sub-project is completed, events of the first sub-project are taken as reference data, the completion time of the subsequent sub-project events is calculated by analogy, meanwhile, the consumption of each material per day and the total amount of each material required by the subsequent sub-project events are combined, the completion time of each subsequent sub-project is comprehensively deduced, after fluctuation occurs in each material consumption of each subsequent sub-project day, the reason of fluctuation of consumable materials is checked, early warning is carried out through a project part, meanwhile, the progress of the project is optimized based on the forward fluctuation reason of each material consumption per day, and the project is guaranteed to be completed in the expected time.
It should be noted that, based on the monitored sub project completion time, the project completion time can be predicted, and when the project completion time is predicted, the project completion time can be increased by one day every working day which cannot be constructed by combining with the local meteorological data of the project. The project sets a predicted completion time for the project information before starting.
In the time prediction of the engineering project, the completion time of the engineering project is predicted based on the maximum simultaneous sub-project number set by the total material demand of the sub-project number set, and is used as the predicted reference time of the engineering project.
It should be understood that the calculation mode of the reference time is to classify the sub-projects according to the material types and the demand, find out a plurality of materials continuously penetrating through all sub-projects in the whole sub-project quantity set according to the material consumption fluctuation curve in the sub-project quantity set, calculate the time of reaching the demand of all the materials penetrating through the whole project through analog reasoning, and serve as the prediction time of the engineering project, and the two prediction times are mutually verified, so that the accuracy of the prediction time is greatly improved.
The maximum number of simultaneous sub-items, that is, the maximum number of simultaneous sub-items, is set for the engineering project to run.
In summary, the method for monitoring construction of the building engineering based on the multidimensional data provided by the invention comprises the steps of splitting an engineering project into a plurality of sub-projects, splitting the sub-projects into a plurality of events, setting a mark event according to the occurrence position of the materials in the plurality of events, calculating the ongoing event of the first sub-project by counting the accumulated usage of each material in the first sub-project and the daily usage of each material in the engineering project, and then estimating the completion time of each sub-project after the total breaking of each material in the first sub-project, by calculating the difference between the accumulated usage of each material in the engineering project and the accumulated usage of each material in the event and the difference between the current consumption of each material in the event and the current consumption of each material in the event, determining all subsequent sub-projects and the events carried out by the subsequent sub-projects, further completing the progress monitoring of the engineering project can be completed by the materials, and meanwhile, by taking the completed process of the first sub-project as reference data, and by combining the similarity of the event of the first sub-project and the consumption of each material in each day and the total consumption of each material required by the subsequent sub-project, the completion time of each sub-project can be estimated, thus the completion time of the engineering project can be completed, the engineering project can be completed in a certain forward time can be guaranteed, and the project can be completed in advance based on the expected forward progress of the project consumption, and the project consumption can be optimized.
