[0003] For example, the invention patent with publication number CN114462953A discloses an intelligent management system for communication engineering, including a host and a mobile terminal. The host includes a database module, a background management module, a terminal server and a central processing unit. Through the setting of the background management module, file transfer, work summary and project reporting can be carried out between departments during use. At the same time, the client of the communication engineering project can also use the mobile terminal to report the situation, transfer files and report the project to the responsible department in the background management module.

[0005] Combined with the above technical solutions, it is found that when currently managing the construction of communication projects, material requirements are usually directly estimated only based on historical data, which deviates greatly from the actual construction situation, resulting in material shortages or surpluses, reducing the accuracy of construction material management, affecting the comprehensiveness and effectiveness of communication project construction management, and making it difficult for the communication project construction management level to achieve the expected results. Summary of the Invention

[0006] In view of the deficiencies of the existing technology, the present invention provides a method and system for intelligent management of communication engineering construction based on CPS technology, which can effectively solve the problems involved in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: The first aspect of the present invention provides an intelligent management method for communication engineering construction based on CPS technology, including: S1. The CPS communication engineering management platform transmits the construction progress related parameters of the target construction area in the current construction period to the communication engineering construction preset model, obtains the data transmission information of the construction progress related parameter transmission process, analyzes and obtains the construction progress data accuracy index of the construction progress related parameter transmission process, and compares it with the construction progress data accuracy threshold preset by the construction management library to determine whether the construction progress related parameters need to be re-transmitted; S2. By transmitting the construction progress related parameters of the target construction area in the current construction period to the communication engineering construction preset model In the preset model of the project construction, the current construction model of the communication project is constructed, thereby obtaining the construction information of the current construction model of the communication project, analyzing and obtaining the construction model accuracy index of the current construction model of the communication project, and comparing it with the construction model accuracy threshold preset in the construction management library, thereby determining whether it is necessary to reconstruct the current construction model of the communication project; S3.

[0008] As a further method, the construction progress data accuracy index of the construction progress associated parameter transmission process is specifically analyzed as follows:

[0009] The data transmission information of the construction progress related parameter transmission process specifically includes the number of erroneous data units of the CPS communication engineering management platform during the data transmission period, the total number of transmitted data units, the maximum data transmission delay duration of the CPS communication engineering management platform during the data transmission period, the data integrity check value of the CPS communication engineering management platform during the data transmission period, the number of illegal accesses to the CPS communication engineering management platform during the data transmission period, and the amount of data leakage of the CPS communication engineering management platform during the data transmission period.

[0010] The data transmission error rate of the CPS communication engineering management platform during the data transmission period is obtained by ratio processing the number of erroneous data units and the total number of transmitted data units.

[0011] The construction progress data accuracy index of the construction progress related parameter transmission process is comprehensively analyzed through the data transmission error rate of the CPS communication engineering management platform during the data transmission period, the maximum data transmission delay duration of the CPS communication engineering management platform during the data transmission period, the data integrity check value of the CPS communication engineering management platform during the data transmission period, the number of illegal accesses to the CPS communication engineering management platform during the data transmission period, and the data leakage amount of the CPS communication engineering management platform during the data transmission period.

[0014] If the construction progress data accuracy index during the transmission of the construction progress associated parameters is less than the construction progress data accuracy threshold preset by the construction management library, the construction progress associated parameters need to be transmitted again.

[0015] As a further method, the construction model accuracy index of the current construction model of the communication project is analyzed in the following specific process:

[0016] The signal power and noise power of the communication equipment belonging to the construction model at each construction moment during the model construction period are ratio-processed to obtain the signal-to-noise ratio of the communication equipment belonging to the construction model at each construction moment during the model construction period. The ratios are then arranged in descending order, and the signal-to-noise ratio that ranks first is extracted and recorded as the maximum signal-to-noise ratio of the communication equipment belonging to the construction model during the model construction period.

[0017] The construction model accuracy index of the current construction model of the communication project is obtained through comprehensive analysis of the real-time signal receiving sensitivity of the communication equipment belonging to the construction model during the model construction period, the voltage fluctuation rate of the communication equipment belonging to the construction model during the model construction period, the maximum signal-to-noise ratio of the communication equipment belonging to the construction model during the model construction period, the real-time network bandwidth of the communication equipment belonging to the construction model during the model construction period, and the construction progress data accuracy index of the construction progress-related parameter transmission process.

[0018] As a further method, the determination of whether the current construction model of the communication project needs to be rebuilt is specifically carried out as follows:

[0019] If the construction model accuracy index of the current construction model of the communication project is greater than or equal to the construction model accuracy threshold preset by the construction management library, there is no need to reconstruct the current construction model of the communication project.

[0020] If the construction model accuracy index of the current construction model of the communication project is less than the construction model accuracy threshold preset by the construction management library, the current construction model of the communication project needs to be rebuilt.

[0021] As a further method, the material execution degree value of the target construction area during the predicted construction period is analyzed in the following specific process:

[0022] The material execution degree value of the target construction area during the predicted construction period is obtained through comprehensive analysis based on the actual available inventory of the target construction area during the predicted construction period, the material quality qualification rate of the target construction area during the predicted construction period, the data transmission error rate of the material warehouse belonging to the target construction area during the predicted construction period, the data integrity check value of the material warehouse belonging to the target construction area during the predicted construction period, and the construction model accuracy index of the current construction model of the communication project. The specific acquisition method is as follows:

[0023]

[0024] Wherein, MDVS represents the material execution degree value of the target construction area during the predicted construction period, AIQ represents the actual available quantity of inventory materials in the target construction area during the predicted construction period, MQP represents the material quality qualification rate of the target construction area during the predicted construction period, ECC represents the data transmission error rate of the material warehouse belonging to the target construction area during the predicted construction period, IIV represents the data integrity check value of the material warehouse belonging to the target construction area during the predicted construction period, PICM represents the construction model accuracy index of the current construction model of the communication project, and e is a natural constant.

[0025] As a further method, the aforementioned early warning reminder of the required materials in the target construction area is analyzed in the following specific process:

[0026] If the material execution level value of the target construction area during the predicted construction period is greater than or equal to the material execution level threshold preset by the construction management library, there is no need to issue an early warning reminder for the required materials in the target construction area.

[0027] If the material execution degree value of the target construction area during the predicted construction period is less than the material execution degree threshold preset by the construction management library, an early warning reminder of the required materials for the target construction area is required.

[0028] The aforementioned early warning reminder for the required materials in the target construction area specifically sends an early warning signal to the CPS communication engineering management platform. The specific content of the early warning is "Insufficient inventory, unable to proceed to the next step of construction, please purchase materials in time."

[0029] The second aspect of the present invention provides an intelligent management system for communication engineering construction based on CPS technology, including: a construction progress data transmission judgment module, which is used for the CPS communication engineering management platform to transmit the construction progress related parameters of the target construction area in the current construction period to the communication engineering construction preset model, obtain the data transmission information of the construction progress related parameter transmission process, analyze and obtain the construction progress data accuracy index of the construction progress related parameter transmission process, and compare it with the construction progress data accuracy threshold preset in the construction management library to determine whether the construction progress related parameters need to be re-transmitted.

[0030] The construction model accuracy index determination module is used to construct the current construction model of the communication project by transmitting the construction progress related parameters of the target construction area in the current construction period to the communication project construction preset model, thereby obtaining the construction information of the current construction model of the communication project, analyzing and obtaining the construction model accuracy index of the current construction model of the communication project, and comparing it with the construction model accuracy threshold preset in the construction management library to determine whether the current construction model of the communication project needs to be rebuilt.

[0031] The material feasibility warning module is used to obtain the communication project construction completion model, perform progress forecasting on the communication project with the current construction model, obtain the required material information of the target construction area during the predicted construction period, analyze the material feasibility value of the target construction area during the predicted construction period, compare it with the material feasibility threshold preset in the construction management library, and finally issue a warning prompt for the required materials in the target construction area.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] Reference Figure 1 As shown, the first aspect of the present invention provides an intelligent management method for communication engineering construction based on CPS technology, including: S1. The CPS communication engineering management platform transmits the construction progress related parameters of the target construction area in the current construction period to the communication engineering construction preset model, obtains the data transmission information of the construction progress related parameter transmission process, analyzes and obtains the construction progress data accuracy index of the construction progress related parameter transmission process, and compares it with the construction progress data accuracy threshold preset in the construction management library, thereby determining whether the construction progress related parameters need to be re-transmitted.

[0042] It should be explained that the construction progress-related parameters of the above-mentioned target construction area during the current construction period mainly include construction duration, construction progress, construction cost management information, project quality, material usage level, financial expenditure level, personnel punch-in management information, material procurement management information, material market information and inventory information, etc.; through on-site collection and automatic recording to the CPS communication engineering management platform, the CPS communication engineering management platform can be directly obtained when used.

[0043] In a specific embodiment, the above-mentioned CPS communication engineering management platform refers to a platform for intelligent management of communication engineering construction. This CPS communication engineering management platform can be connected through the Internet of Things, thereby receiving information related to communication engineering construction through the Internet of Things, and ultimately performing intelligent management operations on the communication engineering construction; the CPS communication engineering management platform is equipped with a network monitoring tool that can obtain data transmission network data during the data transmission process. At the same time, the CPS communication engineering management platform is equipped with a SIEM (Security Information and Event Management) system that can collect, integrate, and analyze logs and event data from different radars through log collection technology and data integration technology, which can be used to obtain each time period. It also has an MD5 (Message Digest) hash algorithm; the above-mentioned communication engineering construction preset model is specifically a customized software model for receiving and processing construction progress-related parameters and performing analysis based on these parameters to support construction management decisions. The communication project after construction is modeled through BIM (Building Information Modeling) technology. The constructed three-dimensional model of the communication project is used for construction simulation and results comparison to improve the intuitiveness and accuracy of project quality assessment, thereby improving the scientificity and accuracy of management decisions of the CPS communication engineering management platform. It can be obtained through the construction management library.

[0044] Specifically, the construction progress data accuracy index during the construction progress associated parameter transmission process is analyzed in the following steps:

[0045] The data transmission information of the construction progress related parameter transmission process specifically includes the number of erroneous data units of the CPS communication engineering management platform during the data transmission period, the total number of transmitted data units, the maximum data transmission delay duration of the CPS communication engineering management platform during the data transmission period, the data integrity check value of the CPS communication engineering management platform during the data transmission period, the number of illegal accesses to the CPS communication engineering management platform during the data transmission period, and the amount of data leakage of the CPS communication engineering management platform during the data transmission period.

[0046] It should be explained that the above-mentioned data transmission period specifically refers to the time period from the start of the CPS communication engineering management platform transmitting the construction progress related parameters of the target construction area in the current construction period to the communication engineering construction preset model to the end of data transmission, which is recorded as the data transmission period. The specific duration is determined by factors such as the network performance between the CPS communication engineering management platform and the communication engineering construction preset model, the size of the construction progress related parameter data, and can be obtained through the SIEM system built into the CPS communication engineering management platform.

[0047] It should be explained that the number of erroneous data units of the above-mentioned CPS communication engineering management platform during the data transmission period, the total number of transmitted data units, the number of illegal accesses to the CPS communication engineering management platform during the data transmission period, and the amount of data leakage of the CPS communication engineering management platform during the data transmission period can all be obtained through the network monitoring tool built into the CPS communication engineering management platform; among them, the number of erroneous data units of the CPS communication engineering management platform during the data transmission period specifically refers to the number of construction progress related parameter data units that failed to be correctly transmitted due to various reasons during the data transmission process, including network failure, protocol mismatch, software vulnerabilities, hardware failures or human operational errors, etc. The number of data units refers to the number of data units that serve as basic transmission units during network data transmission. For example, assuming that the CPS communication engineering management platform is transmitting a construction progress related parameter data set containing 100 data units, these data units represent the progress information of different construction stages, and during transmission During the data transmission process, due to network instability, 5 of the data units failed to be correctly transmitted to the communication engineering construction preset model. These 5 data units that failed to be correctly transmitted are regarded as erroneous data units, and the number of erroneous data units is 5; the total number of data units transmitted specifically refers to the total number of all construction progress related parameter data units sent from the CPS communication engineering management platform to the communication engineering construction preset model during the data transmission process; the maximum data transmission delay of the CPS communication engineering management platform during the data transmission period specifically refers to the maximum time interval from the moment the CPS communication engineering management platform triggers the transmission instruction to the actual start of transmission of the construction progress related parameters; the amount of data leakage of the CPS communication engineering management platform during the data transmission period specifically refers to the amount of unauthorized data that is illegally obtained, accessed, disclosed or used due to various reasons (such as hacker attacks, internal personnel violations, system vulnerabilities, etc.) during the data transmission process of the CPS communication engineering management platform;The data integrity check value of the above-mentioned CPS communication engineering management platform during the data transmission period specifically refers to the data value used to verify the integrity of the data obtained by the CPS communication engineering management platform using the MD5 (message digest) hash algorithm to calculate the transmitted data in order to prevent the construction progress related parameter data from being tampered with or destroyed during the transmission process. It can be obtained through the MD5 (message digest) hash algorithm built into the CPS communication engineering management platform. First, the CPS communication engineering management platform organizes this set of data into a string form, for example: "Construction number = 95, construction progress percentage = 60%, completed project volume = 3000 cubic meters", this string is the original data that needs to be integrity checked, the MD5 algorithm built into the CPS communication engineering management platform will initialize a 128-bit status buffer (consisting of four 32-bit registers A, B, C, and D), and set the initial values ​​of these registers to fixed constants, and input the organized string data into the MD5 algorithm. The algorithm will perform a series of complex bit operations and round function operations on the data, and finally generate a 128-bit hash value, which will be The data is converted into four 32-bit groups and concatenated into a 128-bit string (usually represented by a 32-bit hexadecimal number), for example: "fa12cd45ef6789ab0123456789abcdef". The CPS communication engineering management platform saves this 128-bit string as the data integrity check value and transmits it to the communication engineering construction preset model along with the original data. After receiving the data and the check value, the communication engineering construction preset model calculates the received data according to the same MD5 algorithm to obtain a new hash value. The two check values ​​are then compared. If the two values ​​are the same, it means that the data has not been tampered with or damaged during transmission, and the data integrity is guaranteed. If the two values ​​are different, it means that the data has been tampered with or damaged and is resent. The number of illegal accesses to the CPS communication engineering management platform during the data transmission period specifically refers to the number of access attempts to the CPS communication engineering management platform during the data transmission process without authorization or in violation of security policies. This can be obtained through the SIEM system built into the CPS communication engineering management platform.

[0048] The data transmission error rate of the CPS communication engineering management platform during the data transmission period is obtained by ratio processing the number of erroneous data units and the total number of transmitted data units.

[0049] It should be explained that the data transmission error rate of the above-mentioned CPS communication engineering management platform during the data transmission period specifically refers to the proportion of data units that failed to be correctly transmitted due to various reasons (such as signal interference, equipment failure, network failure, protocol mismatch, software vulnerabilities, etc.) during the data transmission process.

[0050] The construction progress data accuracy index of the construction progress related parameter transmission process is comprehensively analyzed through the data transmission error rate of the CPS communication engineering management platform during the data transmission period, the maximum data transmission delay duration of the CPS communication engineering management platform during the data transmission period, the data integrity check value of the CPS communication engineering management platform during the data transmission period, the number of illegal accesses to the CPS communication engineering management platform during the data transmission period, and the amount of data leakage of the CPS communication engineering management platform during the data transmission period. The specific acquisition method is as follows:

[0051]

[0052] In the formula, ERC represents the data transmission error rate of the CPS communication engineering management platform during the data transmission period, MLD represents the maximum data transmission delay of the CPS communication engineering management platform during the data transmission period, IVV represents the data integrity check value of the CPS communication engineering management platform during the data transmission period, UAA represents the number of illegal accesses to the CPS communication engineering management platform during the data transmission period, LVC represents the amount of data leakage of the CPS communication engineering management platform during the data transmission period, e is a natural constant, and ACPD represents the construction progress data accuracy index during the transmission process of construction progress-related parameters. Illegal access is often accompanied by malicious attacks or improper operations on the network system. These behaviors will destroy the integrity of data transmission and cause errors in data transmission. If the number of illegal accesses is large, the data transmission error rate and data leakage will increase. At the same time, illegal access will cause data to be tampered with or damaged during transmission, thereby reducing the data integrity check value. Excessive illegal access will also increase the maximum data transmission delay because illegal access will occupy network resources, causing network congestion or slow system response, ultimately reducing the construction progress data accuracy index.

[0053] ω1 represents the data accuracy weight coefficient of the data transmission error rate preset by the construction management library, ω2 represents the data accuracy weight coefficient of the maximum data transmission delay duration preset by the construction management library, ω3 represents the data accuracy weight coefficient of the data integrity check value preset by the construction management library, ω4 represents the data accuracy weight coefficient of the number of illegal accesses preset by the construction management library, and ω5 represents the data accuracy weight coefficient of the data leakage amount preset by the construction management library.

[0054] It should be explained that the data accuracy weight coefficients corresponding to the data transmission error rate, the maximum duration of data transmission delay, the data integrity check value, the number of illegal accesses and the amount of data leakage are respectively used to adjust the importance of the data transmission error rate, the maximum duration of data transmission delay, the data integrity check value, the number of illegal accesses and the amount of data leakage in the process of analyzing and obtaining the construction progress data accuracy index. For example, there is a pre-set mapping relationship between the real-time data transmission information and the corresponding data accuracy weight coefficient in the construction management library. The data accuracy weight coefficient corresponding to the real-time data transmission information can be matched through the pre-set mapping relationship. The data transmission error rate, the maximum duration of data transmission delay, the data integrity check value, the number of illegal accesses and the amount of data leakage are respectively matched with the pre-set mapping relationship to obtain the data accuracy weight coefficient corresponding to the data transmission error rate, the data accuracy weight coefficient corresponding to the maximum duration of data transmission delay, the data accuracy weight coefficient corresponding to the data integrity check value, the data accuracy weight coefficient corresponding to the number of illegal accesses and the data accuracy weight coefficient corresponding to the data leakage. In this embodiment, the value range is (0, 1).

[0055] Furthermore, the determination of whether the construction progress-related parameters need to be retransmitted is carried out in the following specific process:

[0056] If the construction progress data accuracy index during the transmission process of the construction progress associated parameters is greater than or equal to the construction progress data accuracy threshold preset by the construction management library, there is no need to re-transmit the construction progress associated parameters; the construction progress data accuracy threshold specifically refers to the critical value used to judge whether the construction progress data accuracy index during the transmission process of the construction progress associated parameters reaches the transmission standard during the data transmission of the construction progress associated parameters, and is used to measure whether the data transmission accuracy is good; the above-mentioned construction progress data accuracy index is greater than or equal to the construction progress data accuracy threshold preset by the construction management library, indicating that the data transmission is accurate, and there is no need to re-transmit the construction progress associated parameters.

[0057] If the construction progress data accuracy index during the construction progress associated parameter transmission process is less than the construction progress data accuracy threshold preset by the construction management library, it indicates that the data transmission is inaccurate, and the construction progress associated parameters need to be re-transmitted.

[0058] S2. By transmitting the construction progress related parameters of the target construction area in the current construction period to the communication project construction preset model, the current construction model of the communication project is constructed, thereby obtaining the construction information of the current construction model of the communication project, and analyzing the construction model accuracy index of the current construction model of the communication project. The index is compared with the construction model accuracy threshold preset in the construction management library to determine whether the current construction model of the communication project needs to be rebuilt.

[0059] It should be explained that the specific construction process of the above-mentioned current construction model of the communication project is that the communication project construction preset model processes the received construction progress related parameters, including data cleaning (removing redundant and erroneous data), data conversion (converting data into a format recognizable by the model) and other steps to ensure the accuracy and consistency of the data; according to the processed construction progress related parameters, the preset model performs model matching and adjustment, including adjusting the model parameter settings, updating the model status information, etc. For example, if the preset number of construction workers is 100 and the actual number of construction workers is 95, the parameter settings of the model are adjusted to change the number of construction workers to 95; on the basis of the communication project construction preset model, combined with the processed construction progress related parameters, through BI M (Building Information Modeling) technology constructs a current construction model of the communication project, which can reflect the actual construction progress and status of the current construction area in real time; the constructed current construction model of the communication project is verified, and the various parameters in the constructed current construction model of the communication project (such as the number of construction workers, construction progress, resource usage, etc.) are compared with the construction progress-related parameters to identify and modify errors or inconsistencies in the model. For example, if it is identified that the construction materials used in the model are 100 tons, and the construction progress-related parameters show that the construction materials used are 99 tons, the construction materials used in the model will be changed to 99 tons to improve the accuracy of the model.

[0060] Specifically, the construction information of the current construction model of the communication project includes the real-time signal receiving sensitivity of the communication equipment belonging to the construction model during the model construction period, the voltage value of the communication equipment belonging to the construction model at each construction moment during the model construction period, the signal power and noise power of the communication equipment belonging to the construction model at each construction moment during the model construction period, and the real-time network bandwidth of the communication equipment belonging to the construction model during the model construction period.

[0061] It should be explained that the above-mentioned model construction period specifically refers to the time period from the start of model construction of the current construction progress to the end of construction, which is recorded as the model construction period. The specific duration is determined by factors such as the amount of construction progress-related parameter data, model construction difficulty, and model construction algorithm; each construction moment refers to the various time points for model construction of the current construction progress, which can be obtained through the SIEM system built into the CPS communication engineering management platform.

[0062] It should be explained that the real-time signal receiving sensitivity of the communication equipment belonging to the above-mentioned construction model during the model construction period, the signal power and noise power of the communication equipment belonging to the construction model at each construction moment during the model construction period can all be obtained through the built-in spectrum analyzer of the communication equipment belonging to the construction model; wherein, the real-time signal receiving sensitivity of the communication equipment belonging to the construction model during the model construction period specifically refers to the signal strength received by the communication equipment belonging to the construction model at each construction moment during the model construction period, which is recorded as the real-time signal receiving sensitivity of the communication equipment belonging to the construction model during the model construction period; the signal power of the communication equipment belonging to the construction model at each construction moment during the model construction period specifically refers to the power value of the signal received by the communication equipment belonging to the construction model at each construction moment during the model construction period; the noise power The rate specifically refers to the power value of the noise received by the communication equipment belonging to the construction model at each construction moment during the model construction period; the voltage value of the communication equipment belonging to the above-mentioned construction model at each construction moment during the model construction period specifically refers to the voltage value of the power supply connected to the communication equipment belonging to the construction model at each construction moment during the model construction period, which can be obtained through the built-in voltmeter of the communication equipment belonging to the construction model; the real-time network bandwidth of the communication equipment belonging to the above-mentioned construction model during the model construction period specifically refers to the data transmission rate that the network to which the communication equipment belongs can provide at each construction moment during the model construction period, which is recorded as the real-time network bandwidth of the communication equipment belonging to the construction model during the model construction period, which can be obtained through the network supervision tool built into the CPS communication engineering management platform.

[0063] The voltage values ​​of the communication equipment belonging to the construction model at each construction moment during the model construction period are averaged to obtain the average voltage value of the communication equipment belonging to the construction model during the model construction period. The maximum and minimum values ​​are located from the voltage values ​​of the communication equipment belonging to the construction model at each construction moment during the model construction period, and difference processing is performed. The difference processing result is compared with the average voltage value of the communication equipment belonging to the construction model during the model construction period to obtain the voltage fluctuation rate of the communication equipment belonging to the construction model during the model construction period.

[0064] It should be explained that the voltage fluctuation rate of the communication equipment belonging to the above construction model during the model construction period specifically refers to the ratio of the variation degree of the voltage value of the communication equipment belonging to the construction model at each construction moment during the model construction period to the average voltage value.

[0065] Furthermore, the construction model accuracy index of the current construction model of the communication project is analyzed in the following specific process:

[0066] The signal power and noise power of the communication equipment belonging to the construction model at each construction moment during the model construction period are ratio-processed to obtain the signal-to-noise ratio of the communication equipment belonging to the construction model at each construction moment during the model construction period. The ratios are then arranged in descending order, and the signal-to-noise ratio that ranks first is extracted and recorded as the maximum signal-to-noise ratio of the communication equipment belonging to the construction model during the model construction period.

The specific acquisition method is as follows:

[0069]

[0070] In the formula, VDV represents the voltage fluctuation rate of the communication equipment belonging to the construction model during the model construction period, SNR represents the maximum signal-to-noise ratio of the communication equipment belonging to the construction model during the model construction period, MNB(t) represents the network bandwidth of the communication equipment belonging to the construction model at the construction time t during the model construction period, ACPD represents the construction progress data accuracy index of the construction progress associated parameter transmission process, SRS(t) represents the signal receiving sensitivity of the communication equipment belonging to the construction model at the construction time t during the model construction period, e is a natural constant, PICM represents the construction model accuracy index of the current construction model of the communication project, and the larger the real-time network bandwidth, the faster the communication equipment can be. Transmit data, reduce delays and errors in the data transmission process, thereby improving the accuracy of construction progress data, and increasing the accuracy index of construction progress data. Building a model based on accurate data will improve the accuracy of the construction model and increase the accuracy index of the construction model; the smaller the voltage fluctuation rate, the more stable the operating voltage of the communication equipment, which will improve the real-time signal reception sensitivity. High sensitivity means that the communication equipment can better receive weak signals, thereby improving the signal-to-noise ratio, enhancing the anti-interference ability of the communication system, and maintaining the stability of data transmission, thereby improving the accuracy of construction progress data, increasing the accuracy index of construction progress data, and thus increasing the accuracy index of the construction model.

[0072] It should be explained that the model accuracy impact factors corresponding to the voltage fluctuation rate, maximum signal-to-noise ratio, real-time network bandwidth, construction progress data accuracy index and real-time signal receiving sensitivity are respectively used to adjust the importance of the voltage fluctuation rate, maximum signal-to-noise ratio, real-time network bandwidth, construction progress data accuracy index and real-time signal receiving sensitivity in the process of analyzing and obtaining the construction model accuracy index. For example, there is a pre-set mapping relationship between the real-time construction information and the corresponding model accuracy impact factor in the construction management library. The model accuracy impact factor corresponding to the real-time construction information can be matched through the pre-set mapping relationship. The voltage fluctuation rate, maximum signal-to-noise ratio, real-time network bandwidth, construction progress data accuracy index and real-time signal receiving sensitivity are respectively matched with the pre-set mapping relationship to obtain the model accuracy impact factor corresponding to the voltage fluctuation rate, the model accuracy impact factor corresponding to the maximum signal-to-noise ratio, the model accuracy impact factor of the real-time network bandwidth, the model accuracy impact factor corresponding to the construction progress data accuracy index and the model accuracy impact factor corresponding to the real-time signal receiving sensitivity.

[0074] Specifically, the determination of whether the current construction model of the communication project needs to be rebuilt is carried out as follows:

[0075] If the construction model accuracy index of the current construction model of the communication project is greater than or equal to the construction model accuracy threshold preset in the construction management library, there is no need to reconstruct the current construction model of the communication project; the construction model accuracy threshold specifically refers to the critical value used to judge whether the construction model accuracy index of the current construction model of the communication project meets the model accuracy standard during the model construction of the current construction progress, and is used to measure whether the construction model accuracy meets the standard; if the construction model accuracy index of the current construction model of the above-mentioned communication project is greater than or equal to the construction model accuracy threshold preset in the construction management library, it means that the current construction model of the communication project is accurate, and there is no need to reconstruct the current construction model of the communication project.

[0076] If the construction model accuracy index of the current construction model of the communication project is less than the construction model accuracy threshold preset by the construction management library, it means that the current construction model of the communication project is not accurate, and the current construction model of the communication project needs to be rebuilt.

[0077] It should be explained that the specific construction process of the above-mentioned construction model of the current construction model of the communication project is that the communication project construction preset model re-processes the data of the received construction progress related parameters, and according to the processed construction progress related parameters, the preset model performs model matching and adjustment. On the basis of the communication project construction preset model, combined with the processed construction progress related parameters, the current construction model of the communication project is constructed.

[0078] S3. Obtain the communication project construction completion model, perform progress forecasting on it together with the current construction model of the communication project, obtain the required material information for the target construction area during the predicted construction period, analyze the material execution degree value for the target construction area during the predicted construction period, compare it with the material execution degree threshold preset in the construction management library, and finally issue an early warning prompt for the required materials for the target construction area.

This helps to ensure the smooth progress of the construction process, improve construction efficiency and quality, ensure the correct installation and commissioning of equipment, and avoid equipment failure and damage. At the same time, comparing the current construction model of the communication project with the communication project construction completion model can intuitively evaluate the construction quality and progress, help to timely discover deviations and problems in construction, and take corresponding corrective measures, help understand the overall layout and details of the communication project, and conduct in-depth analysis of various data of the communication project, such as equipment quantity, material usage, construction time, etc. These data provide strong support for project management and decision-making; the above-mentioned progress prediction processing with the current construction model of the communication project specifically compares and analyzes the communication project construction completion model with the current construction model, and collects the current construction data by comparing and analyzing key elements such as structure, function, and construction progress. The actual construction progress data in the previous construction model, such as the amount of work completed, the remaining amount of work, and the estimated completion time, are compared with the expected data in the construction completion model. During the comparison process, it is necessary to fully consider the impact of various factors on the construction progress, such as the availability of equipment, material supply, and staffing. Through comparison, the gaps between the current construction model and the construction completion model in terms of construction progress, quality, cost, and other aspects can be clearly identified. Based on the identified gaps, the causes of these problems can be further analyzed, such as the delayed arrival of equipment, shortage of material supply, and insufficient staffing. Combining the current construction progress data with various influencing factors, the future construction progress of the communication project can be predicted. The prediction results include the estimated completion time and existing risk points. Finally, the progress prediction results are provided to the CPS communication project management platform, which can make corresponding management decisions based on the prediction results, such as adjusting the construction schedule and optimizing resource allocation. During the construction process, new data is continuously collected and the model is continuously optimized. Through continuous optimization, the accuracy and authenticity of the model can be improved, providing more accurate support for subsequent progress prediction and management decisions.

[0083] The material inventory in the target construction area during the predicted construction period is multiplied by the material loss rate preset in the construction management library to obtain the inventory material loss in the target construction area during the predicted construction period, and the material inventory in the target construction area during the predicted construction period is subtracted from the inventory material loss in the target construction area during the predicted construction period to obtain the actual available inventory material in the target construction area during the predicted construction period.

[0084] It should be explained that the actual available quantity of inventory materials in the above-mentioned target construction area during the predicted construction period specifically refers to the quantity of materials that can actually be used for construction activities in the target construction area after taking into account material losses during the predicted construction period.

[0085] The number of erroneous data units and the total number of transmitted data units of the material warehouse belonging to the target construction area during the predicted construction period are ratio processed to obtain the data transmission error rate of the material warehouse belonging to the target construction area during the predicted construction period.

[0086] It should be explained that the data transmission error rate of the material warehouse belonging to the above-mentioned target construction area during the predicted construction period specifically refers to the ratio between the number of erroneous data units that occur during the data transmission process of the material warehouse belonging to the target construction area during the predicted construction period and the total number of data units transmitted.

[0087] Furthermore, the material execution degree value of the target construction area during the predicted construction period is analyzed in the following specific process:

When the data transmission error rate is low, the possibility of data errors or loss during transmission is small, which helps to maintain data integrity. As the data integrity check value increases, building a model based on accurate data will improve the accuracy of the construction model, increase the construction model accuracy index, improve the accuracy of the material demand forecast, and increase the material execution value. A larger actual available quantity of inventory materials and material quality qualification rate means that the construction area has sufficient material supply and reliable material quality, which helps to improve the material execution degree, thereby increasing the material execution value.

For example, there is a pre-set mapping relationship between the real-time required material information and the corresponding executable weight factor in the construction management library. The executable weight factor corresponding to the real-time required material information can be matched through the pre-set mapping relationship. The actual available quantity of inventory materials, the qualified rate of material quality, the data transmission error rate, the data integrity check value and the construction model accuracy index are respectively matched with the pre-set mapping relationship to obtain the executable weight factor of the actual available quantity of inventory materials, the executable weight factor corresponding to the material quality qualified rate, the executable weight factor corresponding to the data transmission error rate, the executable weight factor of the data integrity check value and the executable weight factor corresponding to the construction model accuracy index. In this embodiment, the value range is (0, 1).

[0093] Specifically, the early warning prompt for the required materials in the target construction area is analyzed in the following steps:

[0094] If the material execution degree value of the target construction area during the predicted construction period is greater than or equal to the material execution degree threshold value preset by the construction management library, there is no need to issue an early warning prompt for the required materials in the target construction area; the material execution degree threshold value specifically refers to the critical value used to judge whether the material execution degree value of the target construction area during the predicted construction period reaches the construction execution standard during the material execution degree assessment of the target construction area, and is used to measure whether the inventory materials are sufficient; if the material execution degree value of the above-mentioned target construction area during the predicted construction period is greater than or equal to the material execution degree threshold value preset by the construction management library, it means that the materials are sufficient, and there is no need to issue an early warning prompt for the required materials in the target construction area.

[0095] If the material execution degree value of the target construction area during the predicted construction period is less than the material execution degree threshold preset by the construction management library, it means that there is a shortage of materials, and an early warning reminder of the required materials for the target construction area is required.

[0096] The aforementioned early warning reminder for the required materials in the target construction area specifically sends an early warning signal to the CPS communication engineering management platform. The specific content of the early warning is "Insufficient inventory, unable to proceed to the next step of construction, please purchase materials in time."
