Abstract
Description
Technical Field
[0001] The present invention relates to the field of management systems, and in particular to an engineering project management system. Background Art
[0002] After the establishment of an engineering project, a corresponding system is needed to manage it and realize intelligent management to achieve efficient implementation and effective management of the engineering project.
[0003] The current engineering project management systems and platforms are able to manage the project's budget cost, design, procurement, construction period, site, quality and safety.
[0004] Among them, the construction period is a management content that both the construction party and the owner pay close attention to. The length of the construction period directly affects the economic benefits of the construction company and whether it can meet the requirements of the owner. In the existing technology, the construction period is generally calculated based on the project information, such as the size of the project, the type of project, the number of construction personnel and equipment, and the construction process. The above construction period calculation method can accurately estimate the construction period under normal circumstances. For example, in areas without power restrictions, the equipment can be used normally. However, during the peak power consumption period in summer and when the power load is large, in order to ensure the electricity consumption of the people, some cities will issue power restriction notices and engineering projects will be restricted. When encountering restricted situations, most of the construction equipment that consumes electricity cannot be used normally, which will cause the progress of the project to stagnate and extend the construction period. Therefore, the existing construction period calculation method does not take the power restriction situation into consideration, resulting in inaccurate prediction of the construction period. Summary of the invention
[0005] The purpose of the invention is to manage engineering projects and estimate accurate construction periods.
[0006] To achieve the above object, the present invention provides a construction project management system, the system comprising:
[0007] Access control unit, used to manage access control of the construction site corresponding to the project;
[0008] The monitoring unit is used to monitor the engineering site corresponding to the engineering project and display the monitoring information in the background;
[0009] The procurement unit is used to manage the procurement of engineering materials required for the project;
[0010] Material management unit, used to manage materials corresponding to engineering projects;
[0011] Personnel management unit, used to manage personnel entering the project site;
[0012] Safety management unit, used for safety management of the project site;
[0013] The construction period management unit is used to calculate the first construction period based on the project information, estimate the number of power-cut days corresponding to the first construction period, and calculate the estimated construction period corresponding to the project based on the first construction period and the number of power-cut days.
[0014] Among them, the engineering project management system of the present invention can manage engineering projects, including: using the access control unit to perform access control management on the engineering site corresponding to the engineering project, using the monitoring unit to monitor the engineering site corresponding to the engineering project, and displaying the monitoring information in the background, using the procurement unit to manage the procurement of engineering materials required in the engineering project, using the material management unit to manage the materials corresponding to the engineering project, using the personnel management unit to manage the personnel entering the engineering site, and using the security management unit to perform security management of the engineering site.
[0015] In addition, a construction period management unit is also designed in this system. The construction period management unit calculates the first construction period based on the project information, estimates the number of power-limited days corresponding to the first construction period, and calculates the estimated construction period corresponding to the project based on the first construction period and the number of power-limited days. The estimated construction period calculated by the construction period management unit in the present invention not only takes into account the first construction period affected by the project information in the traditional way, but also takes into account the number of power-limited days corresponding to the first construction period, and then combines the first construction period and the number of power-limited days to calculate and obtain the accurate estimated construction period corresponding to the project. Compared with the traditional construction period estimation method, this system takes into account the number of power-limited days caused by power-limited factors, making the estimated construction period more accurate.
[0016] In order to accurately obtain the number of power-cut days, the present invention estimates the number of power-cut days corresponding to the first construction period and specifically includes:
[0017] Obtaining geographical location information of the construction site corresponding to the engineering project;
[0018] Obtain historical weather data, historical power restriction data, historical power supply data and historical power load data of the power grid corresponding to the geographical location information of the project site;
[0019] Construct a power supply data prediction model based on historical weather data and historical power supply data of the power grid;
[0020] Build an electricity consumption data prediction model based on historical weather data and historical power grid load data;
[0021] Based on the historical power supply data and the historical power load data of the power grid, the historical power supply and power load difference data are obtained;
[0022] Construct a power restriction data prediction model based on historical power supply and power load difference data and historical power restriction data;
[0023] Based on the historical weather data and the first construction period, the weather forecast model is used to estimate the weather data corresponding to the first construction period;
[0024] Obtain power supply estimation data corresponding to the first construction period based on construction period weather data and power supply data estimation model;
[0025] Obtain the electricity consumption estimation data corresponding to the first construction period based on the construction period weather data and the electricity consumption data estimation model;
[0026] Obtaining power supply and power load difference estimation data based on power supply estimation data and power consumption estimation data;
[0027] The number of power-limited days is obtained based on the power supply and power load difference estimation data and the power-limited data estimation model.
[0028] Among them, the applicant's research found that whether a region is subject to power rationing is based on the local power overload. The power consumption exceeds the power supply, making the power grid overloaded. In order to ensure the safety of the power grid and people's livelihood electricity, power rationing is required. The construction period is an estimated construction period, and the issuance of the limited regulations is temporary. Therefore, in order to accurately estimate the construction period, the present invention needs to accurately estimate whether there will be power rationing during the construction period and the number of days of power rationing.
[0029] The present invention first obtains the geographical location information of the engineering site corresponding to the engineering project. The purpose of obtaining the geographical location information is to obtain the corresponding historical weather data, historical power restriction data, historical power supply data of the power grid and historical power load data of the power grid. Because the southern part of my country is mainly hydropower generation, the power generation is large when water resources are abundant, and the power generation is small when water resources are insufficient, which in turn affects the power supply. Therefore, when the power supply is insufficient, it will also lead to power restriction. A power supply data prediction model can be constructed through historical weather data and historical power supply data of the power grid, and then the corresponding power supply data can be obtained when the weather data is obtained. Since weather factors are also related to power consumption data, such as hot and cold weather, the power consumption of air conditioners will increase. Therefore, a power consumption data prediction model can be constructed using historical weather data and historical power load data of the power grid, and then the corresponding power consumption data can be obtained when the weather data is obtained.
[0030] By using the historical power supply data and the historical power load data of the power grid, the historical power supply and power load difference data can be obtained. The purpose of obtaining the historical power supply and power load difference data is to grasp the limiting rules and quantify the standards for power restriction, so as to facilitate the subsequent prediction of power restriction. That is, the historical power supply and power load difference data and the historical power restriction data can be used to construct a power restriction data estimation model, and the power restriction can be estimated using the power restriction data estimation model.
[0031] Using historical weather data and the first construction period, the weather prediction model is used to estimate the corresponding construction period weather data during the first construction period; and using the construction period weather data and the power supply data prediction model to estimate the corresponding power supply estimation data during the first construction period; and using the construction period weather data and the power consumption data prediction model to estimate the corresponding power consumption estimation data during the first construction period; and then based on the power supply estimation data and the power consumption estimation data, the power supply and power load difference estimation data are obtained; and then based on the power supply and power load difference estimation data and the power restriction data estimation model, the power restriction days are obtained. Through the above method, the present invention studies the conditions and laws of power restriction and the influencing factors, and constructs a corresponding estimation model, which can accurately estimate the power restriction days.
[0032] In some embodiments, historical rainfall data is obtained based on historical weather data, and a power supply data prediction model is constructed based on the historical rainfall data and the historical power supply data of the power grid. The power supply in southern my country mainly relies on water conservancy power supply, and hydropower generation is associated with rainfall data. Therefore, historical rainfall data is extracted from historical weather data, and then a power supply data prediction model can be constructed based on the historical rainfall data and the historical power supply data of the power grid.
[0033] The applicant has found that the usual cycle of project management is from the beginning of the project to the end after the project is completed, but this will have the following problems: when the project is delivered and the problems that occur during use are difficult to determine whether they are problems with the project itself or problems with the way it is used. Therefore, in order to effectively manage the project and effectively supervise the quality of the project, the system in the present invention also includes a quality supervision unit, which is used to supervise the use of the project subject corresponding to the project after the project is delivered. That is, after the project is delivered, the use process of the project is supervised to ensure that the construction quality and use quality of the project meet the corresponding requirements.
[0034] In order to supervise the engineering subject during use, the quality supervision unit specifically includes:
[0035] Several patrol sub-units are used to patrol the main body of the project and obtain real-time information about the main body of the project;
[0036] The approval subunit is used to approve the modification of the main body of the project. After approval, the corresponding area of the main body of the project will be marked;
[0037] The judgment subunit is used to obtain the real-time information collected by the patrol subunit, analyze the real-time information, and determine whether there are any unmarked areas under renovation in the main project. If so, an alarm will be issued and a notification message will be generated and sent to the preset terminal.
[0038] Among them, the real-time information of the main body of the project can be obtained through several patrol sub-units. Through the real-time information of the main body of the project, it can be determined which areas are under construction and which areas are not under construction. The modification of the main body of the project can be approved through the approval sub-unit, and the corresponding area of the main body of the project can be marked after approval; the judgment sub-unit can analyze the real-time information to determine whether there are unmarked areas in the main body of the project that are being renovated. If so, an alarm will be issued, and a notification message will be generated and sent to the preset terminal. That is, it is determined whether there are unapproved modifications in progress. These unapproved modifications may affect the quality of the project. Therefore, these unapproved modifications are alarmed, and notification messages are generated and sent to the preset terminal, which can avoid problems caused by illegal modifications of engineering projects during use.
[0039] The applicant further discovered that the current project management systems are all managed after the preliminary projects are determined, and are aimed at planned projects. For temporary or emergency projects, there is a lack of corresponding management systems in the prior art, and they are all temporarily managed by a project team manually. In order to manage emergency projects, the system in the present invention also includes an emergency project management unit, which includes:
[0040] A drone subunit, the drone subunit is used to carry the image acquisition unit and fly over the road collapse area;
[0041] An image acquisition subunit, the image acquisition subunit is used to acquire a landslide image corresponding to a road landslide area;
[0042] A scanning subunit, the scanning subunit is used to scan the road collapse area to obtain a scanning signal;
[0043] A processing subunit, the processing subunit is used to analyze the landslide image to obtain the landslide amount, and the processing subunit is used to process the scanning signal to obtain the stone information in the road landslide area;
[0044] A calculation subunit is used to calculate the time required to complete the clearing of soil and rocks corresponding to the road collapse area based on the landslide amount and stone information.
[0045] Among them, the emergency engineering management unit in the present invention can quickly and accurately calculate the time required to complete the clearing of soil and rocks corresponding to the road collapse area after the road collapses, and then can quickly and accurately estimate the road opening time, and can effectively manage the time for repairing the collapsed road.
[0046] Among them, after the road collapses, the core project is to clear the collapsed soil and rocks and then restore the road to smooth flow. The existing project for clearing the collapsed soil and rocks needs to first calculate the amount of collapse, and then estimate the time required for clearing the collapse based on the amount of collapse. The above-mentioned calculation method for the collapse clearing time is accurate for collapses that are all soil, but the above-mentioned calculation method is inaccurate for collapses that contain soil and rocks, especially soil and rocks with large rocks, because the collapse is mainly cleared by the loader to transfer the soil and rocks. However, when the rocks are large and exceed the maximum capacity of the loader bucket, a crusher is needed to break the large rocks into small rocks, and then the loader is used for loading and transfer. The existing collapse transfer calculation method does not take into account the time required for breaking large rocks. Therefore, the existing calculation method for the time required for collapse clearing is inaccurate. In order to accurately calculate the time required for clearing the collapse, the calculation idea of the time required for clearing the collapse in the present invention is: respectively calculate the time required for the loader to load the soil and rocks and the time required for the crusher to break the large rocks, and then add the two times to obtain the accurate time required to complete the clearing of the soil and rocks corresponding to the road collapse area.
[0047] The method for obtaining the amount of landslide is as follows: using a drone subunit carrying an image acquisition unit to fly over the road landslide area to acquire the landslide image corresponding to the road landslide area; using a processing subunit to analyze the landslide image to obtain the amount of landslide, based on which the time required for a loader to load soil and rocks, and the time required for a transport vehicle to transport soil and rocks can be calculated, using a scanning subunit to scan the road landslide area to obtain a scanning signal, and by processing the scanning signal to obtain stone information in the road landslide area, such as stone size information, the time required to crush the stone can be obtained by the stone size information, wherein the crushing of stones only crushes large stones that exceed the maximum capacity of the loader bucket, and small stones do not need to be crushed.
[0048] Among them, in some embodiments, the time required to complete the clearing of soil and rocks corresponding to the road collapse area is calculated based on the landslide amount and the stone information, specifically including:
[0049] The stones whose volume is greater than or equal to the preset volume are classified as the first type of stones, and the stones whose volume is less than the preset volume are classified as the second type of stones; the purpose of classifying the stones is to divide the stones into two types: the stones that can be directly loaded by the loader and the stones that need to be crushed by the crusher before the loader can load them. The preset volume can be the maximum capacity of the loader bucket;
[0050] Based on the stone information in the road collapse area, the number n of the first type of stones and the volume sizes V1 to Vn of the first type of stones are obtained;
[0051] Based on the volume of the first type of stone, the first time T1 to Tn required for crushing the first type of stone into a plurality of second type of stones is obtained; the time required for crushing stones of different sizes is different, for example, a large stone may need to be crushed multiple times to obtain a second type of stone, and some first type of stones may only need to be crushed once to obtain a second type of stone, therefore, the crushing time of first type of stones of different sizes is different;
[0052] The second time Tk required to transfer the collapsed soil and rocks is calculated based on the landslide volume. The applicant found that at the site of transferring the collapsed soil and rocks, the loader and the transport vehicle are carried out simultaneously, so both of them need corresponding time to complete the transfer of the collapsed soil and rocks. Therefore, the final time required to transfer the collapsed soil and rocks is the larger value of the time required for the loader to complete the loading of all the collapsed volumes and the time required for the transport vehicle to complete the transportation of all the collapsed volumes, that is, Tk = max(Tq, Tp), Tq = Z ÷ (L*B) * E1, Z is the landslide volume, E1 is the time required for a single loading by the loader, L is the number of loaders, B is the maximum capacity of the loader bucket, and Tq is the third time; Tp = Z ÷ (R*Y) * E2, E2 is the time required for the transport vehicle to complete one transportation, R is the maximum loading volume of the transport vehicle, Y is the number of transport vehicles, and Tp is the fourth time;
[0053] The crushing time Tw is calculated as follows: Tw = (T1 + Tn) / m, where m is the number of crushers. When multiple crushers are used for crushing at the same time, the crushing time Tw is calculated in the above manner.
[0054] The time required to complete the clearing of the soil and rocks corresponding to the road collapse area is Tv, which is calculated as: Tv = (Tk + Tw) / p, where p is the influencing factor. The influencing factor is determined by the applicant based on actual research findings, because whether the crushing of rocks and the transfer of soil and rocks can be carried out at the same time needs to be confirmed based on the actual site. If the crushing of rocks and the transfer of soil and rocks can be carried out at the same time, then P is greater than 1. If they cannot be carried out at the same time, then P is equal to 1. The specific value of P can be adjusted according to actual needs.
[0055] The most important project in the construction of a hydropower station project is dam construction, and the core task of dam construction is dam pouring. The progress of dam concrete pouring is mainly restricted by the capacity of the mixing system and the transportation system. Most of the existing concrete high dams use cable cranes or cable cranes + tower cranes to transport and pour concrete. For example, hydropower stations are usually built in river valleys, so it is necessary to set up cable cranes on the mountains on both sides of the river valley, and then use cable cranes to lift concrete for pouring.
[0056] Cable cranes are an important means of delivering concrete. They need to be operated frequently during the pouring of dams. In addition, large hydropower stations are poured in large volumes, and the cable cranes and hanging tanks used are also large. Large hanging tanks are more susceptible to strong winds. However, the dam is located in a river valley, and the wind in the valley is often stronger than the wind on the plains. The airflow enters the narrow terrain from the open area, the channel becomes smaller, the air circulation speed increases, and the wind force increases suddenly. In addition, the hanging tank is suspended in the air and has a large volume. As a result, when the hanging tank is lifted by the cable crane in strong winds, it will shake more violently, which poses corresponding safety hazards.
[0057] Moreover, the weather in the river valley is different from the daily weather. The wind in the river valley is caused by many factors. The traditional weather forecast form cannot accurately predict whether there will be strong winds in the river valley. Therefore, strong winds often blow when the cable crane is lifting the hanging tank during the pouring of the dam in the hydropower station project construction. At this time, safety accidents are prone to occur. In order to solve this safety problem, the present invention has designed corresponding improvements. The specific idea is that the river valley usually has an entrance and an exit, and the wind speed is detected at the entrance and the exit respectively. When the wind speed is large, it means that there will be strong winds in the river valley. The hanging tank in the lifting process is protected from the wind to increase the safety of the lifting hanging tank.
[0058] Wherein, the engineering project is a hydropower station construction project, and the system further comprises:
[0059] The first anemometer and the second anemometer are respectively installed at the two ends of the valley where the engineering project is located, and are respectively used to monitor and obtain wind speed information at the two ends of the valley; the first anemometer and the second anemometer can be used to detect the wind speed at the two ends of the valley, i.e., the entrance and exit of the valley. When the wind speed is high, strong winds will appear in the surface valley, and the hanging tank in the hoisting state needs to be protected.
[0060] An information transmission unit, the information transmission unit is used to transmit wind speed information to a control unit;
[0061] A control unit is used to determine whether the wind speed information is greater than a threshold value. If so, a wind protection treatment is performed on the cable crane hoisting unit corresponding to the engineering project.
[0062] The windproof protection treatment of the cable crane hoisting unit corresponding to the project specifically includes:
[0063] Check whether there is a hanging tank in the cable crane lifting unit in operation. If not, shut down the cable crane lifting unit. If not, shut down the crane to avoid operation in windy weather and wait until the strong wind ends before operating again. If a standby cable crane is turned on, the standby cable crane will lift the windproof and diversion units to both sides of the hanging tank, and control the windproof and diversion units to run synchronously with the hanging tank until the hanging tank returns to the base of the cable crane lifting unit. Use the standby cable crane to lift the windproof and diversion units to both sides of the hanging tank, block and divert the airflow blowing to the hanging tank on both sides, reduce the speed of the airflow and change the direction of the airflow, thereby reducing the swing amplitude of the hanging tank and enhancing its safety. The windproof and diversion units run synchronously with the hanging tank to protect the hanging tank from wind on the one hand, and ensure that the hanging tank can operate normally and complete the lifting task on the other hand, until the hanging tank returns to the base of the cable crane lifting unit, and then retract the hanging tank, and start the lifting task again after the strong wind weather ends.
[0064] Wherein, the windproof and diversion unit comprises:
[0065] A docking piece is used to dock with the lifting end of the spare cable crane; the docking piece is used to facilitate docking with the lifting end of the spare cable crane or the lifting equipment to facilitate lifting, so that the wind-proof and flow-guiding piece connected to the docking piece can be lifted and moved.
[0066] The windproof and flow-guiding piece is connected to the docking piece and is used for providing windproof and flow-guiding protection to the hanging tank.
[0067] One or more technical solutions provided by the present invention have at least the following technical effects or advantages:
[0068] This system can estimate and obtain accurate construction period.
[0069] This system can monitor the use of engineering projects after delivery.
[0070] This system can manage emergency engineering projects, especially can accurately estimate the duration required for clearing road landslides.
[0071] This system can enhance the safety of hydropower station construction projects. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention may also be implemented in other ways different from those within the scope of this description. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.
[0080] Embodiment 1;
[0081] Please refer to Figure 1 , Figure 1 The present invention provides a construction project management system, which includes:
[0082] Access control unit, used to manage access control of the construction site corresponding to the project;
[0083] The monitoring unit is used to monitor the engineering site corresponding to the engineering project and display the monitoring information in the background;
[0084] The procurement unit is used to manage the procurement of engineering materials required for the project;

[0088] The construction period management unit is used to calculate the first construction period based on the project information, estimate the number of power-cut days corresponding to the first construction period, and calculate the estimated construction period corresponding to the project based on the first construction period and the number of power-cut days.
[0089] Among them, the access control unit can be a management unit with a vehicle entrance and a personnel entrance, with a corresponding management background, which can enter the corresponding vehicle information and personnel information, can verify the identity of personnel and vehicles entering and leaving the project site, and has corresponding vehicle gates and door gate devices. After the identity verification is passed, the corresponding vehicle gates and door gates are opened, and the entry and exit information of the corresponding vehicles and personnel can also be recorded.
[0090] Among them, the monitoring unit includes several monitors or cameras or corresponding image and video acquisition devices, which transmit the collected information to the background through information transmission equipment, such as data transmission lines or optical cables or wireless transmission methods, and display it in the background. The display content includes image content, location, time, etc., which is convenient for management personnel to understand the construction site situation in real time.
[0091] Among them, the procurement unit can be managed by corresponding procurement management software. For example, the procurement unit includes an order module, which is used by procurement personnel to place orders according to the materials to be purchased, a review module, which is used to review the orders of the order module, and a payment module, which is used to pay for the orders that have passed the review. In actual applications, other functions or modules may also be included, and the embodiments of the present invention do not make corresponding limitations.
[0092] Among them, there are a lot of materials on the construction site, and effective management of the materials is required. The material management unit can be used to manage the materials corresponding to the project. For example, after the materials arrive at the construction site, they are stored and numbered. When the materials need to be used, they are applied for. After the application is approved, the materials are issued and the use of the materials is recorded. At the same time, the stored materials are waterproofed and fireproofed, and the quality and validity period of the materials are supervised.
[0093] Among them, the personnel management unit can be used to manage the personnel entering the construction site, such as verifying the identity of the personnel when entering the construction site. The personnel management unit can include several wearable terminals. The wearable terminals have the function of collecting image information, location information and physical index information. The collected information can be transmitted to the background to perform corresponding management on each person entering the construction site. Image information can be collected by a camera, and location information can be collected by a positioning device, such as a GPS positioning device and a Beidou positioning device. The physical index information collection instrument can be a human body information collector or a vital sign intelligent collector, etc. By collecting physical index information, it can be determined whether the person is healthy or has sudden physical discomfort, and treatment can be quickly carried out. The work intensity on the construction site is high, and personnel are prone to physical problems. Real-time monitoring can reduce the probability of physical problems in personnel and achieve rapid treatment.
[0094] Among them, the construction period management unit can be used to calculate the first construction period based on the project information. The project information is the information related to the project construction that can be obtained before the construction of the project starts, such as the project type, scale, number of equipment, number of personnel, construction technology, etc., and the corresponding first construction period is calculated by combining this information with some commonly used means in this field. For example, the construction period calculation method recorded in the public patent CN202010973483.9 can be used. The calculation method of the first construction period is not described in detail in the present invention, and the calculation can be performed by means known to those skilled in the art. The focus of the present invention is to estimate the number of power-limited days corresponding to the first construction period, so that the estimated construction period can be accurately obtained.
[0095] In the embodiment of the present invention, the estimated number of power-cutoff days corresponding to the first construction period specifically includes:
[0096] Obtaining geographical location information of the construction site corresponding to the engineering project;
[0097] Obtain historical weather data, historical power restriction data, historical power supply data and historical power load data of the power grid corresponding to the geographical location information of the project site;

[0105] Obtaining power supply and power load difference estimation data based on power supply estimation data and power consumption estimation data;
[0106] The number of power-limited days is obtained based on the power supply and power load difference estimation data and the power-limited data estimation model.
[0107] The geographic location information may be obtained through geographic location query software or map software, or may be obtained through a positioning device, such as a GPS positioning device or a Beidou positioning device.
[0108] Among them, after obtaining the geographical location information of the project site, the historical weather data corresponding to the geographical location information can be obtained by querying the meteorological database or meteorological website. By querying the local power supply or power grid database or network with the geographical location information, the historical power restriction data, the historical power supply data of the power grid and the historical power load data of the power grid can be obtained.
[0109] Based on the historical power supply data and the historical power load data of the power grid, the difference data between the historical power supply and the power load can be obtained by subtracting them.
[0110] Among them, the power supply data estimation model is a data estimation model. A training set is constructed by historical weather data and historical power supply data of the power grid, and the training is input into the original estimation model to obtain the power supply data estimation model. The power supply data estimation model can adopt corresponding functions or models or software. The embodiment of the present invention does not make corresponding limitations. For example, the power supply data prediction method recorded in CN112381266A can be adopted.
[0111] Among them, similar to the method of constructing a power supply data prediction model, a power consumption data prediction model can be constructed based on historical weather data and historical power load data of the power grid. A training set is constructed based on historical weather data and historical power load data of the power grid. The training set is input into the original prediction model for training to obtain the power consumption data prediction model. The power consumption data prediction model can adopt corresponding functions or models or software. The embodiments of the present invention do not make corresponding limitations. For example, the power load prediction method recorded in CN117748498A can be adopted.
[0112] Among them, similar to the construction method of the previous two models, a training set can be constructed based on the historical power supply and power load difference data and the historical power restriction data, and then machine learning is performed using the training set. The power restriction data estimation model can be obtained by training the corresponding model. Since there is a correlation between the historical power supply and power load difference data and the historical power restriction data, machine learning can be used to learn the relationship between the two to obtain the corresponding estimation model. The selection of the specific model can be adjusted according to actual needs, and the embodiment of the present invention does not make corresponding limitations.
[0113] Among them, the weather prediction model can use the weather forecast function in the meteorological department or meteorological unit or meteorological database to realize weather forecast. As long as the predicted location and predicted time are entered, the predicted weather data can be obtained. The predicted location is the construction site, and the predicted time can be obtained based on the first construction period. For example, if the construction period is 3 years, then the prediction is the weather 3 years after the start date of the construction period.
[0114] Then, based on the construction period weather data and the power supply data estimation model, the power supply estimation data corresponding to the first construction period can be estimated; then, based on the construction period weather data and the power consumption data estimation model, the power consumption estimation data corresponding to the first construction period can be estimated; then, based on the power supply estimation data and the power consumption estimation data, the power supply and power load difference estimation data can be obtained; finally, based on the power supply and power load difference estimation data and the power restriction data estimation model, the power restriction days can be obtained.
[0115] In the embodiment of the present invention, historical rainfall data is obtained by screening from historical weather data, and then a power supply data estimation model is constructed based on the historical rainfall data and historical power supply data of the power grid.
[0116] Among them, in the embodiment of the present invention, the system also includes a quality supervision unit, which is used to supervise the engineering subject corresponding to the engineering project during use after the engineering project is completed and delivered.
[0117] Among them, in the embodiment of the present invention, the quality supervision unit specifically includes:
[0118] Several patrol sub-units are used to patrol the main body of the project and obtain real-time information about the main body of the project. The patrol sub-units can be used for patrolling the main body of the project by corresponding personnel wearing patrol terminals, or by installing monitoring equipment in the corresponding areas of the main body of the project to realize patrolling;
[0119] The approval subunit is used to approve the modification of the main body of the project. After approval, a mark is set for the corresponding area of the main body of the project. When the main body of the project needs to be modified, the modification construction party needs to upload the modification construction plan to the approval subunit for approval. The mark can be an electronic mark or a physical mark, which is not specifically limited in the present invention.
[0120] The judgment subunit is used to obtain the real-time information collected by the patrol subunit, analyze the real-time information, and judge whether there is an unmarked area in the main project that is undergoing renovation. If so, an alarm is issued and a notification message is generated and sent to the preset terminal. The specific judgment method can use image processing means, such as analyzing the image to determine whether there is a mark in the collected image of the renovation construction area. If not, it is judged that there is no mark, or if it is an electronic mark, a detection instruction is sent to the renovation area. If no signal is received from the electronic mark, it is judged that there is no mark in the renovation area.
[0121] In the embodiment of the present invention, the system further includes an emergency engineering management unit, and the emergency engineering management unit includes:
[0122] A drone subunit, the drone subunit is used to carry the image acquisition unit and fly above the road collapse area; wherein most drones in the prior art are equipped with corresponding cameras and image processing software and can be used directly;
[0123] An image acquisition subunit, the image acquisition subunit is used to acquire a landslide image corresponding to a road landslide area;
[0124] A scanning subunit, the scanning subunit is used to scan the road collapse area to obtain a scanning signal;
[0125] A processing subunit, the processing subunit is used to analyze the landslide image to obtain the landslide amount, and the processing subunit is used to process the scanning signal to obtain the stone information in the road landslide area;
[0126] A calculation subunit is used to calculate the time required to complete the clearing of soil and rocks corresponding to the road collapse area based on the landslide amount and stone information.
[0127] Among them, the measurement of landslide volume can be achieved through photo measurement technology, which mainly relies on drone oblique photogrammetry technology. This method uses the oblique photography camera carried by the drone to collect image data from multiple angles (including vertical and oblique directions), and processes these data through professional software to generate a high-precision three-dimensional geographic information model, thereby realizing the rapid calculation of earthwork volume. The advantage of drone oblique photogrammetry technology is that it can provide centimeter-level measurement accuracy, and it is flexible to operate and low in cost, which is very suitable for the rapid measurement of earthwork volume such as landslide volume.
[0128] The specific steps are as follows:
[0129] Data collection: Use the drone oblique photography system to simultaneously collect image data from vertical and four specific oblique angles.
[0130] Data processing: Use professional software to process the collected image data and generate a digital surface model (DSM).
[0131] Earthwork volume calculation: Deviation correction is performed through ArcGIS and other software to quickly calculate the earthwork change.
[0132] This method not only improves the efficiency and accuracy of measurement, but also reduces work difficulty and cost, making the measurement of earthwork volume more convenient and efficient.
[0133] Among them, the scanning subunit can use geological radar or rock detection instrument. Geological radar is based on the principle of ground resistivity. By observing the change of underground resistivity, the position and size of the stone can be determined. The rock detection instrument obtains information about underground materials by measuring underground wave velocity, density, resistance, magnetic induction and other parameters, and then determines the existence, nature and distribution of stones.
[0134] The high-frequency narrow pulse electromagnetic waves generated by the geological radar are transmitted to the earth through the antenna. The propagation speed and attenuation rate in the earth depend on the dielectric and electrical conductivity of the rock. In the process of propagation, if the conductive properties of the rock change, part of the transmitted wave may be reflected. The receiver detects the reflected signal or the directly transmitted signal, amplifies and digitizes it, and stores it on the digital tape recorder for data processing and display.
[0135] Geological radar is a special instrument used for field observation, generally including transmitting antenna and transmitter, receiving antenna and receiver, and control components with built-in microprocessor or directly using portable microcomputer. The transmitter converts the DC power supplied by the DC power supply into a high-frequency, narrow pulse AC signal, and transmits electromagnetic waves of fixed frequency to the detected medium through the transmitting antenna. The receiving antenna receives the echo signal and inputs it into the receiver. After amplification and conversion into digital signals, it is transmitted to the control component for superposition, calculation, and storage. The cross-sectional image is displayed in real time on the LCD display, and can be printed and copied. The observation data can be stored on a floppy disk, or transmitted to an external computer through the standard interface inside the machine for more detailed data processing, color display, and drawing of color cross-sectional diagrams. In order to conduct detection at different depths at the same time and improve construction efficiency, one transmitter or multiple receivers can be used for simultaneous observation. The latest instruments are equipped with transmitting and receiving antennas of multiple frequencies, and several frequencies can be selected or observed according to different geological tasks and construction conditions to obtain more underground information.
[0136] Among them, in the embodiment of the present invention, the time required for completing the clearing of soil and rocks corresponding to the road collapse area is calculated based on the landslide amount and the stone information, specifically including:
[0137] Stones with a volume greater than or equal to a preset volume are classified as first-category stones, and stones with a volume less than the preset volume are classified as second-category stones; the preset volume can be set according to actual needs, such as according to the maximum capacity of a loader bucket, and the present invention does not make specific limitations.
[0138] Based on the stone information in the road collapse area, the number n of the first type of stones and the volume sizes V1 to Vn of the first type of stones are obtained;
[0139] Obtaining first times T1 to Tn required for crushing the first type of stone into a plurality of second type of stones based on the volume of the first type of stone;
[0140] The second time Tk required to transfer the collapsed soil and rocks is calculated based on the amount of landslide, Tk = max (Tq, Tp), Tq = Z ÷ (L*B) * E1, Z is the amount of landslide, E1 is the time required for a single load by the loader, L is the number of loaders, B is the maximum capacity of the loader bucket, and Tq is the third time; Tp = Z ÷ (R*Y) * E2, E2 is the time required for a transport vehicle to complete a transport, R is the maximum load of the transport vehicle, Y is the number of transport vehicles, and Tp is the fourth time;
[0141] Calculate the crushing time Tw, which is calculated as follows: Tw = (T1 + Tn) / m, where m is the number of crushers;
[0142] The time required to complete the clearing of soil and rocks corresponding to the road collapse area is Tv, which is calculated as: Tv = (Tk + Tw) / p, where p is the influencing factor.
[0143] Among them, the calculation method of the first time can be determined according to the volume of the first type of stone. For example, the following calculation method can be used, Tn=to*Vn / Vt, where Vt is the preset volume and to is the time required for the crusher to crush a second type of stone.
[0144] Wherein, in the embodiment of the present invention, the engineering project is a hydropower station construction project, and the system further includes:
[0145] The first anemometer and the second anemometer are respectively installed at two ends of the river valley where the engineering project is located, and the first anemometer and the second anemometer are respectively used to monitor and obtain wind speed information at the two ends of the river valley; wherein, the two ends of the river valley refer to the entrance or exit of the river valley, and the first anemometer and the second anemometer are respectively installed on the mountain surface close to the river surface on both sides of the entrance and exit of the river valley.
[0146] An information transmission unit, wherein the information transmission unit is used to transmit wind speed information to the control unit; the information transmission unit may be a communication module, such as a 5G communication module or a wired data transmission method.
[0147] The control unit is used to determine whether the wind speed information is greater than a threshold value, and if so, to perform wind protection on the cable crane hoisting unit corresponding to the project. The threshold value can be set according to the actual project requirements, and the present invention does not specifically limit it.
[0148] Among them, in the embodiment of the present invention, the windproof protection treatment of the cable crane hoisting unit corresponding to the engineering project specifically includes:
[0149] Check whether there is a hoisting tank in the cable crane hoisting unit. If not, shut down the cable crane hoisting unit. If the standby cable crane is turned on, the standby cable crane will hoist the wind-proof and diversion units to both sides of the hoisting tank, and control the wind-proof and diversion units to run synchronously with the hoisting tank until the hoisting tank returns to the base of the cable crane hoisting unit.
[0150] Among them, the cable cranes all have existing control software and tables. Through the corresponding control software and monitoring information as well as the cable crane operation information, it can be obtained whether there is a lifting tank in the cable crane lifting unit. During the lifting process of the cable crane, the control system of the cable crane can control the lifting speed and direction. Therefore, by docking with the control system of the cable crane, the corresponding parameters can be obtained, such as whether there is a lifting tank in lifting, as well as the position, operating speed, and operating direction of the lifting tank, etc.
[0151] Among them, the schematic diagram of the dam hoisting and pouring of the hydropower station construction project is as follows Figure 2 As shown, the dam 7 is built in the river valley 2, the foundation of the cable crane will be built on the mountains 1 on both sides of the valley, and the main equipment 3 of the cable crane will be erected on the foundation, and then the cable 4 will be erected between the two mountains, and the cable will be equipped with a cable car 5, which drives the hanging tank 6 to move.
[0152] Among them, the present invention builds a new spare cable crane next to the original cable crane. The load and requirements of the spare cable crane can be lower than those of the normally used cable crane, because the spare cable crane is used to lift the wind-proof diversion unit. The weight of the wind-proof diversion unit is lower than the weight of the hanging tank fully loaded with concrete. Therefore, the spare cable crane can be a low-cost and small cable crane, and the cable of the spare cable crane can be a certain safety distance away from the cable of the normally used cable crane. On the one hand, it can avoid interfering with the lifting of the hanging tank of the normal cable crane. On the other hand, in windy weather, the wind-proof diversion unit may be shaken by the strong wind. Setting a corresponding safety distance can avoid the wind-proof diversion unit from colliding with the cable and hanging tank of the normal cable crane, thereby ensuring safety.
[0153] Among them, in the embodiment of the present invention, the windproof and diversion unit includes:
[0154] A docking piece, the docking piece is used to dock with the lifting end of the standby cable crane; the docking piece is used to facilitate docking with the lifting end of the standby cable crane or the lifting equipment for lifting, so as to realize lifting and movement of the windproof and deflecting piece connected to the docking piece. In order to prevent the docking piece from shaking violently in windy weather during the lifting process, the docking piece is preferably docked with the lifting end of the standby cable crane in a fixed connection manner, such as a threaded connection manner. Usually, the lifting end of the standby cable crane is a hook, and the hook is connected by a movable connection through a lifting ring. However, this movable connection manner will cause relatively strong shaking in windy weather. Therefore, the present invention replaces the hook with a suspension rod, and a screw hole is provided at the lower end of the suspension rod. The docking piece is a screw rod, and the screw rod is inserted into the screw hole and fixedly connected to the suspension rod to achieve docking. The two are fixedly connected, which can reduce shaking in windy weather.
[0155] The windproof and flow-guiding piece is connected to the docking piece and is used for providing windproof and flow-guiding protection to the hanging tank.
[0156] Please refer to Figure 3 , Figure 3 The structural schematic diagram corresponding to one embodiment of a windproof deflector is shown. The windproof deflector may include: a crossbar 8, a windproof net 9, a plurality of deflectors 10 and a counterweight 11. The crossbar can be conveniently connected to a docking member, and the crossbar can also open the windproof net to achieve a better windproof effect. The upper end of the windproof net is fixedly connected to the crossbar, and the lower end of the windproof net is fixedly connected to the counterweight. The counterweight may be a plurality of counterweight blocks, or a counterweight rod, etc. The embodiment of the present invention does not specifically limit this. The deflector may be a deflector made of plastic or wood materials, and the deflection direction of the deflector may be directed toward the left and right sides of the hanging pot to prevent the airflow from directly acting on the hanging pot. The windproof net is provided with a hollow area 12, and the guide plates are evenly arranged in the hollow area. The upper and lower ends of the guide plates are fixedly connected to the windproof net at the upper and lower ends of the hollow area. The windproof net is a flexible net with evenly distributed air holes, which can facilitate airflow to pass through. The airflow generated by strong wind slows down after passing through the windproof net, and the direction of the airflow is guided by the guide plates to both sides of the hanging pot to avoid blowing directly to the hanging pot, thereby providing windproof and diversion protection for the hanging pot.
[0157] Please refer to Figure 4 , Figure 4The structural schematic diagram corresponding to another embodiment of the windproof deflector, the windproof deflector has another embodiment: the windproof deflector includes a frame 13 and a windproof net, the frame is in the shape of a triangular prism, the top of the frame is fixedly connected to the docking piece 14, and the windproof net is fixedly installed on the side of the frame. The windproof net is a flexible net with evenly distributed air holes, which can facilitate the passage of air. The airflow generated by the strong wind slows down after passing through the windproof net, and the airflow direction is guided by the guide plate to both sides of the hanging pot to avoid blowing directly to the hanging pot, thereby protecting the hanging pot from wind and diverting. The purpose of using a triangular prism frame is that the side edges of the triangular prism and the sides on both sides form a streamlined shape to facilitate breaking wind and reduce resistance, and windproof protection of the hanging pot can be achieved while reducing resistance.
[0158] Among them, corresponding wind-proof and diversion units are provided on both sides of the hanging tank, which can block and protect the airflow blowing towards the hanging tank from both sides of the valley.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
