[0040] The intelligent analysis module is used to perform intelligent analysis on the engineering cost data based on the constructed engineering management model, obtain the engineering cost analysis results, and integrate the engineering cost analysis results into the engineering management model.

[0041] The above-mentioned implementation mode of the present invention proposes an intelligent engineering cost data management system for construction projects, which can obtain the relevant engineering cost data involved in the construction project from the data source in real time through the data acquisition module, wherein the obtained engineering cost data can be approved by the three-party approval module based on the relevant quotation data obtained to determine the specific project or scheme to be adopted, and can effectively make corresponding adjustments to the real-time changes of the cost data, thereby improving the real-time level of engineering cost data management. At the same time, based on the three-party approval method, it is confirmed that the corresponding scheme or project is finally selected according to the engineering cost, which can effectively improve the reliability and management level of the overall management of the project. Through the engineering management module, an engineering management model is constructed based on the construction project, and the relevant cost / quotation data is integrated into the engineering management model, which can carry out the whole process and overall engineering cost management of the construction project based on BIM technology, and at the same time, the engineering management model is intelligently analyzed based on the intelligent analysis module, effectively improving the intelligent level and management level of the engineering cost for the construction project, effectively improving the effect and intelligent level of engineering cost data management, and meeting the needs of modern construction projects for engineering cost data management.

[0042] Among them, the system of the present invention can be built based on a server or intelligent terminal built for a single construction project, and can also be built based on data processing terminals such as cloud servers. The present invention does not make specific limitations here.

[0043] Preferably, the system also includes a project display module for visually displaying the project management model.

[0044] The engineering management model includes building environment data, building structure data, construction data, full-process construction data, cost budget data and acceptance data.

[0045] Through the project display module, the project management model can be visualized, which allows managers or users to have an intuitive and detailed understanding of the entire process of the construction project and related project cost data. It is also convenient for managers or owner users to comprehensively control and manage the cost information of the construction project based on the project management model, thereby improving the management level of project cost data.

[0046] Preferably, the data acquisition module includes a designated acquisition unit and a channel acquisition unit;

[0047] The designated acquisition unit is used to interactively connect with a preset data port, and acquire the real-time designated engineering cost data from the designated data source through the data port;

[0048] The channel acquisition unit is used to obtain quotation information provided by users and extract corresponding engineering cost data based on the quotation information. Users include owners, engineering construction parties and suppliers, etc. The quotation information provided includes project, parameters, price and introduction information.

[0049] Among them, data sources include supplier servers, third-party trading platforms, human resources platforms, etc.

[0050] According to the actual situation of the construction plan of the construction project, the relevant cost data in the construction project (such as labor cost, equipment cost, key material cost, etc.) can be associated, and the corresponding data source can be specified for the price data of the relevant projects, so that the system can automatically extract the price data of the relevant projects from the specified data source to complete the automatic update of the engineering cost data of the relevant projects. Based on the updated engineering cost data, the relevant data in the engineering management model is updated in real time, and the corresponding engineering cost budget, estimate and other data are also updated synchronously, which effectively improves the real-time performance of engineering cost data management.

[0051] Among them, for projects with designated data sources, once the data source designation and authorization are completed, the approval of the project data is considered completed. When the relevant data in the data source changes, the quotation data of the relevant project is automatically updated.

[0052] In one scenario, for key materials needed in construction projects (such as cement, steel bars, etc.), the system is connected to the online quotation system of the corresponding supplier, and the price information of the corresponding key materials is extracted from the online quotation system through a designated unit, and the price data of the corresponding materials is updated according to the extracted price information.

[0053] Preferably, the designated acquisition unit includes an interface unit and a capture unit;

[0054] The interface unit is used to set the corresponding data source for the specified engineering cost project, and establish a data interaction connection with the corresponding data source after completing the interface authorization, so that the specified acquisition unit can access the corresponding data source;

[0055] The capture unit is used to capture relevant data of the specified engineering cost items from the data source through data capture technology.

[0056] For data such as raw material data or labor cost data, they can be connected to the corresponding data source through a data interface, and the corresponding raw material data, labor cost data, equipment-related data, etc. can be obtained from the data source (such as supplier websites, third-party sales platforms, human resources systems, etc.) through data capture technology, which facilitates the timely updating of engineering cost data and improves the level of intelligence in data acquisition.

[0057] Preferably, the channel acquisition unit includes a form unit and a record unit;

[0058] The form unit is used by the user to generate a quotation form for a specified engineering cost project, complete the quotation form according to the relevant information of the specified engineering cost project, and submit the quotation form to the three-party approval module; the quotation form includes the engineering cost form provider, project, parameters, unit price, quantity and introduction information; the introduction information includes image recording information and voice recording information;

[0060] Among them, for the engineering price information finalized face-to-face between users, the relevant engineering price item information can be manually uploaded and entered through the form recording unit, and the quotation form can be submitted to the system, which can meet the needs of engineering cost information entry in various situations and improve the convenience of system use. Among them, in order to facilitate the subsequent multi-user review and confirmation of the entered engineering cost information, it is necessary to upload corresponding introduction information when submitting the engineering cost form to further verify and introduce the authenticity of the submitted quotation form, so as to improve the integrity and authenticity of the quotation form record.

[0061] In one scenario, for the relevant forms submitted for the purchase of construction materials, after completing the quotation form for the purchase of construction materials, the construction purchaser will fill in the relevant rental information in the form, and further record the corresponding quotation contract image information and the voice introduction information of the corresponding person in charge in the corresponding form information through the recording unit. In the subsequent three-party review process, the owner user and the management user can review and confirm the quotation form, and by viewing the relevant information in the form and the pictures and voice recording information accompanying the form, they can fully understand the authenticity and necessity of the purchase of construction materials, etc., and thus approve the request for the purchase of this batch of construction materials, so as to improve the transparency of the disclosure of construction material purchase costs and the rationality of the expenditure. It helps to improve the level of project management.

[0062] Preferably, the recording unit includes an image acquisition unit and a voice recording unit;

[0063] The image acquisition unit is used to collect image information related to the engineering cost project in real time, and integrate the collected image information into the corresponding quotation form;

[0064] The voice recording information is used to collect the user's voice recording information and integrate the collected voice recording information into the corresponding quotation form.

[0065] For different recorded information, relevant information can be collected and recorded by means of pictures, video images or voice recording, and the recorded information can be integrated into the corresponding quotation form for subsequent viewing or listening by other users. This helps to improve the adaptability of key information recording and can be used in different information recording scenarios.

[0066] Preferably, the voice recording unit includes a voice collection unit and an enhancement processing unit;

[0067] The voice collection unit is used to collect the user's voice signal data in real time;

[0068] The enhancement processing unit is used to perform enhancement processing on the acquired voice signal data, improve the quality of the voice signal data, obtain enhanced voice signal data, and integrate the enhanced voice signal data into the corresponding quotation form.

[0069] In one scenario, in actual use, since a large amount of information entry occurs at the construction site, and the construction site is noisy (construction noise, personnel noise, etc.), there is a lot of on-site interference information, which can easily cause the voice recording information entered through the recording unit to be interfered with, resulting in insufficient clarity of the recorded information, affecting the accuracy of subsequent information recording and the effect of listening to the information during the subsequent user review process. Therefore, in the above implementation, an enhancement processing unit is also specially set in the voice recording unit to enhance the acquired voice signal data to improve the quality of the voice signal data, thereby improving the recording effect of the recorded information for the quotation form, helping to improve the accuracy of information recording, and at the same time improving the user experience of other users in the subsequent multi-party review process.

[0070] Preferably, the voice recording unit further includes an extraction unit;

[0071] The extraction unit is used to perform text extraction based on the enhanced voice signal data, translate the voice signal data into text information, and integrate the text information into a corresponding quotation form.

[0072] The voice-to-text method can also help improve the convenience of information recording, making it easier for subsequent users to understand the voice-recorded information during the review process of the quotation form information.

[0080] 12) Calculate the signal-to-noise parameter E(i) of each IMF component based on the obtained characteristic parameters, where the variable i=1, 2, ... K-1 corresponds to each IMF component:

[0081]

[0082] 13) According to the obtained signal-to-noise parameters E(i), obtain the variable i corresponding to the maximum value of the signal-to-noise parameter E(i), and use the value of i as the partition parameter H:

[0083]

[0084] Among them, argmax(*) represents the function that maximizes the target;

[0085] Wavelet threshold processing is performed on each IMF component obtained, including:

[0086] 21) For the IMF component marked as high-frequency IMF component i (t) Perform wavelet decomposition, where the variables i = H + 1, ... K correspond to each IMF component respectively, the wavelet basis used in the wavelet decomposition is Sym9, and the number of wavelet decomposition layers is 4; obtain the high-frequency wavelet coefficients w of the IMF components j,k and low-frequency wavelet coefficients e j,k; The variables j = 1, 2, 3, 4 correspond to the number of wavelet decomposition layers, and the variables k = 1, 2, ... T correspond to the length of the wavelet coefficients;

[0087] 22) For the obtained high-frequency wavelet coefficient w j,k Perform threshold processing to obtain the high-frequency wavelet coefficient w′ after threshold processing j,k :

[0088] Get each wavelet coefficient w j,k , when the wavelet coefficient w j,k When it is greater than or equal to the preset threshold wT, the wavelet coefficients are subjected to the first threshold processing:

[0089]

[0090] When the wavelet coefficient w j,k When it is less than the preset threshold wT and greater than or equal to 0, the wavelet coefficients are subjected to the second threshold processing:

[0091]

[0092] When the wavelet coefficient w j,k When it is less than 0 and greater than the preset threshold -wT, the third threshold processing is performed on the wavelet coefficients:

[0093]

[0094] When the wavelet coefficient w j,k When it is less than or equal to the preset threshold -wT, the fourth threshold processing is performed on the wavelet coefficients:

[0095]

[0096] Among them, w′ j,k represents the wavelet coefficient after threshold processing, where the variable j = 1, 2, 3, 4 corresponds to the number of wavelet decomposition layers, the variable k = 1, 2, ... T corresponds to the length of the wavelet coefficient, y represents the preset retention parameter, where 0.5 ≤ y ≤ 0.99; wT represents the preset threshold, where |w j | represents the amplitude of the wavelet coefficient, med(|w j |) represents the wavelet coefficient w j The middle value of the corresponding amplitude, T represents the length of the wavelet coefficient; α represents the preset positive adjustment parameter, where 0.1≤α<10; β represents the preset negative adjustment parameter, where 0.1≤β≤10, and β>α is satisfied;

[0098] Reconstruct the enhanced speech signal data A′(t) according to the low-frequency IMF components, the high-frequency IMF components after threshold processing, and the residual amount:

[0099]

[0100] The enhanced voice signal data is integrated into the corresponding quotation form.

[0101] In one scenario, the decomposition parameter K is obtained by using a center frequency method, a residual index evaluation method, etc. to confirm the value of the optimal decomposition parameter K. Alternatively, the value of the decomposition parameter K is directly specified based on experience.

[0102] In view of the situation that the voice recording information is disturbed and the clarity is affected by the environmental noise factors at the construction site, the above embodiment of the present invention proposes a technical solution for enhancing the acquired voice signal data based on an enhancement processing unit. Among them, based on the acquired voice signal data, basic signal windowing and framing processing is first performed to unify the sampling data of the signal at each moment, and the obtained voice signal data is further decomposed based on VMD to obtain the IMF components corresponding to the voice signal data; wherein, considering the high and low frequency variation characteristics of the IMF components, the IMF components are divided into high and low frequencies, wherein in the process of division, the division parameter H is introduced to accurately obtain the high and low frequency dividing lines of multiple IMF components; considering the fluctuation characteristics of each IMF component to the actual voice signal and the noise signal, the characteristic parameters of the signal and the signal-to-noise parameters are especially combined to feedback the similarity of each IMF component to the standard voice signal, and the IMF components with sudden changes in the signal-to-noise parameters are selected as the dividing line, thereby dividing the high and low frequency characteristics of the IMF components. Based on the high-frequency IMF components obtained by division (considered to contain noise interference), a wavelet threshold processing-based method is used to eliminate the noise of the high-frequency IMF components. A 4-segment threshold processing method is proposed, which can adaptively eliminate the interference of noise based on the feedback of the high-frequency wavelet coefficients on the noise at the construction site. Paired wavelet coefficient processing is performed through the positive-negative and high-low correspondence of the high-frequency wavelet coefficients, which helps to improve the adaptability of wavelet threshold processing to speech signal data, effectively eliminate the noisy noise interference at the construction site, and effectively improve the signal quality of the high-frequency part. Finally, the signal is reconstructed by combining the IMF components after threshold processing. The obtained speech signal data effectively improves the signal-to-noise ratio, eliminates the interference of environmental noisy noise, highlights the useful human voice part in the speech signal, and improves the quality of the recorded speech signal data, which helps to lay the foundation for further information extraction or playback based on the recorded speech signal data.

The form information to be approved will be transmitted to different users respectively. After receiving the quotation form to be approved, the user can obtain the corresponding quotation form data and complete the approval and information confirmation through the corresponding approval unit, which helps to provide remote approval functions for users from all parties and facilitate users to review the relevant cost data during the construction process. The approval records of all users will be recorded in the project cost data management log through the recording unit, which is convenient for further management of the approval data and historical data recording.
