[0001] The present invention relates to the technical field of project management, and in particular to a power engineering infrastructure project management system and method. Background Art

[0002] With the development of the economy, the demand for electricity continues to grow. Building more and higher-quality transmission line towers will help build a stronger power grid and improve power transmission capacity to meet the growing demand for electricity. Therefore, a power engineering infrastructure project management system and method is needed.

[0003] Existing technologies such as the invention patent application with announcement number CN109670771A disclose a power engineering infrastructure project management system, which includes a monitoring platform system, a mobile phone APP system, an information entry system, and a behavior camera system; the information entry system is used to enter information about personnel, vehicles, and construction machinery; the behavior camera system is used to conduct real-time video monitoring of personnel's work behavior, and the operating conditions of vehicles and construction machinery; the mobile phone APP system is used to generate video data of pre-shift and post-shift meetings, as well as work pre-control management data; the monitoring platform system is used to automatically identify the characteristics of personnel, vehicles, and construction machinery entering the site based on personnel, vehicle, and construction machinery information and real-time video monitoring information, and automatically determine whether the conditions for access to the construction site are met. This invention provides video monitoring information on the work conditions and safety control of the construction site, displays the work safety conditions of the construction site in real time, and is used by safety management personnel to complete safety control work at the construction site, thereby improving the work efficiency of safety management personnel.

[0004] The above scheme has the following technical problems: 1. The above scheme only conducts real-time video monitoring of the construction site and lacks the generation of targeted construction plans. The above scheme does not involve the generation of targeted construction plans based on specific construction data, and cannot optimize the construction process according to the characteristics of different towers, thereby reducing the overall construction quality and efficiency of the power project.

[0005] 2. The above scheme only focuses on the monitoring and management of personnel, vehicles and construction machinery, and does not consider the construction process mechanics and environmental factors. During the tower construction process, the mechanical parameters and environmental data of different towers are different, and the construction schemes used are also different. The above scheme does not consider the impact of mechanical and environmental factors on the construction process. It is difficult to ensure the scientificity and safety of the construction scheme under different conditions, which reduces the overall construction quality and construction safety of the power project.

[0006] 3. When faced with such changes during the construction process, the above-mentioned scheme lacks corresponding real-time response measures and can only discover surface violations and safety hazards. It is difficult to fundamentally solve dynamic problems in the construction process. At the same time, the construction plan is adjusted according to abnormal data. At the same time, the above-mentioned scheme is more about handling and notifying violations of personnel and equipment. It lacks the decision-making basis and ability to adjust the overall construction plan according to the actual situation during the construction process. It cannot meet the safety needs during the construction process and increases construction hazards. Summary of the Invention

[0007] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a power engineering infrastructure project management system and method.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a power engineering infrastructure project management system, including the following units: a scheme design unit, used to collect the construction data of the target tower, analyze and obtain the basic construction difficulty index of the target tower, and judge whether the target tower adopts the suspended pole holding process. If the target tower uses the suspended pole holding process, the mechanical parameters and environmental data of the target tower during the construction process are collected. According to the mechanical parameters during the construction process, the mechanical response index of each assembly process is analyzed to generate the optimal lifting sequence. According to the environmental data during the construction process of the target tower, the safety construction index of each suspension height is analyzed to obtain the optimal suspension height, and then the tower construction plan is set.

[0009] The dynamic correction unit is used to collect abnormal data of construction equipment, construction tower, construction environment and safety monitoring according to the preset optimal lifting sequence and optimal suspension height.

[0010] The project management unit is used to manage the construction project based on abnormal data of construction equipment, abnormal data of construction tower, abnormal data of construction environment and abnormal data of safety monitoring.

[0011] Preferably, the construction process is changed, and the specific change process is as follows: the pole tilt angle change data includes the pole tilt angle deviation rate and the tilt angle deviation trend index, and the pole suspension height change data includes the pole suspension height maximum change rate and the suspension height fluctuation rate.

[0012] If the tilt angle deviation rate of the pole is greater than the preset standard angle deviation rate or the tilt angle deviation trend index is greater than the preset standard tilt angle deviation trend index, it indicates that the pole tilt angle is abnormal. The deviation angle between the pole and each suspension line is obtained through horizontal modeling. The direction correction factor corresponding to each suspension line deviation angle and the torque compensation amount corresponding to each tilt angle deviation rate are obtained from the database. In this way, the torque compensation amount of the pole and the direction correction factor of each suspension line are obtained. The torque compensation amount of the pole is multiplied by the direction correction factor of each suspension line to obtain the compensation torque of each suspension line. The hydraulic system of each suspension line of the pole performs compensation according to the compensation torque.

[0013] If the maximum change rate of the suspension height of the boom is greater than the preset standard suspension height change rate or the suspension height fluctuation rate is greater than the preset standard suspension height fluctuation rate, it indicates that the suspension height of the boom is abnormal. The height deviation compensation amount corresponding to each suspension height change rate and the compensation time corresponding to each suspension height fluctuation rate are obtained from the database. The height deviation compensation amount is divided by the compensation time to obtain the speed compensation amount of the boom lifting speed. The vertical lifting speed of the boom construction equipment is increased by the speed compensation amount.

[0014] In this way, a plan for changing the construction process is obtained: the hydraulic system of each suspension line of the boom is compensated according to the compensation torque, and the vertical lifting speed of the boom construction equipment increases at a speed equal to the compensation amount.

[0015] Preferably, the analysis obtains the current construction plan, and the specific analysis process is as follows: the construction equipment abnormality data includes the construction equipment abnormality rate and the construction equipment abnormality trend index, and the construction equipment abnormality rate and the construction equipment abnormality trend index are substituted into the construction equipment abnormality index calculation formula to obtain the construction equipment abnormality index; the construction tower body abnormality data includes the construction tower body abnormality rate and the construction tower body abnormality trend index, and the construction tower body abnormality rate and the construction tower body abnormality trend index are substituted into the construction tower body abnormality index calculation formula to obtain the construction tower body abnormality index; the construction environment abnormality data includes the construction environment abnormality rate and the construction environment abnormality trend index, and the construction environment abnormality rate and the construction environment abnormality trend index are substituted into the construction environment abnormality index calculation formula to obtain the construction environment abnormality index; the safety monitoring abnormality data includes the safety monitoring abnormality rate and the safety monitoring abnormality trend index, and the safety monitoring abnormality rate and the safety monitoring abnormality trend index are substituted into the construction safety abnormality index calculation formula to obtain the construction safety abnormality index.

[0016] The construction equipment abnormality index, construction tower abnormality index, construction environment abnormality index and construction safety abnormality index are input into the construction status model to obtain the output result of the current construction status model. The output result values include 1, 2, 3 and 4.

[0017] When the output result is 1, stop construction and change the construction project. When the output result is 2, replace the construction tower. When the output result is 3, replace the construction equipment. When the output result is 4, replace the construction personnel.

[0018] On the other hand, the present invention provides a method for managing power engineering infrastructure projects, comprising the following steps: Step 1, scheme design: collecting construction data of the target tower, analyzing to obtain the basic construction difficulty index of the target tower, judging whether the target tower adopts a suspended pole holding process, and if the target tower adopts a suspended pole holding process, collecting the mechanical parameters and environmental data of the target tower during construction, and analyzing to obtain the mechanical response index of each assembly process based on the mechanical parameters during construction, thereby generating an optimal lifting sequence, and analyzing to obtain the safety construction index of each suspension height based on the environmental data during construction of the target tower, thereby obtaining the optimal suspension height, and then setting a tower construction plan.

[0019] Step 2: Dynamic correction: According to the preset optimal lifting sequence and optimal suspension height, collect abnormal data of construction equipment, construction tower, construction environment and safety monitoring.

[0020] Step 3: Project management: Carry out construction project management based on abnormal data of construction equipment, abnormal data of construction tower, abnormal data of construction environment and abnormal data of safety monitoring.

[0021] The beneficial effects of the present invention are: 1. The present invention first uses the scheme design unit to collect the target tower construction data to analyze the basic construction difficulty index and determine whether to adopt the suspended pole holding process; if adopted, the mechanical parameters and environmental data are collected, and the mechanical response index and the safe construction index are analyzed to set the tower construction plan. Secondly, the dynamic correction unit is used to collect abnormal data of construction equipment, tower body, environment and safety monitoring. Finally, the project management unit is used to analyze the abnormal data and then carry out construction project management. The present invention accurately evaluates the basic construction difficulty index, scientifically selects the suspended pole holding process and dynamically generates the optimal lifting sequence and safe suspension height, which significantly improves the scientificity and feasibility of the construction plan.

[0022] 2. During the construction process, close attention is paid to mechanical parameters and environmental data. Based on mechanical parameters such as the maximum stress ratio of the boom, the maximum strain value of the tower main material and the overall overturning moment of the system, the mechanical response index of each assembly process is analyzed and the optimal lifting sequence is determined. This can effectively improve construction efficiency and reduce mechanical risks during the construction process. At the same time, combined with environmental data such as wind vibration coefficient, air density, windward area and system quality, the safety construction index of each suspension height is calculated to determine the optimal suspension height, thereby enhancing the safety and stability of construction under different environmental conditions.

[0023] 3. The present invention collects construction stress data in real time, thereby accurately controlling the hydraulic compensation amount and ensuring the stable operation of the construction equipment. At the same time, the change data of the arm inclination angle and the suspension height are monitored in real time and timely adjustments are made to ensure that the construction process of the construction tower meets the requirements and reduce the impact of erroneous construction. At the same time, the present invention uses the construction status model for analysis based on abnormal data from various aspects such as construction equipment, tower, environment and safety monitoring, and can accurately judge the current construction status and make preset decisions based on the output results, thereby increasing construction safety.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] according to Figure 1 As shown, the present invention provides a power engineering infrastructure project management system, which includes the following units: a scheme design unit, a dynamic deviation correction unit, a project management unit and a database.

[0029] The scheme design unit is connected to the dynamic deviation correction unit and the database respectively, and the project management unit is connected to the dynamic deviation correction unit.

[0030] The scheme design unit is used to collect the construction data of the target tower, analyze and obtain the basic construction difficulty index of the target tower, and determine whether the target tower adopts the suspended pole holding technology. If the target tower adopts the suspended pole holding technology, the mechanical parameters and environmental data of the target tower during the construction process are collected. According to the mechanical parameters during the construction process, the mechanical response index of each assembly process is analyzed to generate the optimal lifting sequence. According to the environmental data during the construction process of the target tower, the safety construction index of each suspension height is analyzed to obtain the optimal suspension height, and then the tower construction plan is set.

[0031] In a specific embodiment, the construction data of the target tower is collected, and the specific collection process is as follows: the construction data of the target tower includes the soil type index, shallow static load test force, slope, foundation burial depth and single foundation weight of the target tower.

[0032] The soil particle size distribution of the target tower is determined by screening, and the soil type index corresponding to each soil particle size distribution is obtained from the database to obtain the soil type index of the target tower. The shallow static load test force of the target tower is collected by an earth pressure box, and the slope of the target tower is collected by a fixed inclinometer. The foundation burial depth of the target tower is determined by electromagnetic wave reflection image using a ground penetrating radar. The segmented tower components are weighed separately using a floor scale, and the total weight of each base is accumulated to obtain the single base weight of the target tower.

[0033] It should be noted that the preset allowable stress is the allowable stress threshold corresponding to the tower material. When it exceeds the preset value, the risk of the boom breaking is greater. The specific parameters are obtained through experiments.

[0034] In a specific embodiment, the analysis obtains the foundation construction difficulty index, and the specific analysis process is as follows: the soil type index, shallow static load test force, slope, foundation burial depth and single foundation weight of the target tower are substituted into the foundation construction difficulty index calculation formula to obtain the foundation construction difficulty index of the target tower.

The specific values are set by staff, for example 0.4, 0.1, is 0.2 and is 0.3.

[0038] The basic construction difficulty index of the target tower is compared with the basic construction difficulty index threshold in the database. When the basic construction difficulty index of the target tower is greater than or equal to the basic construction difficulty index threshold in the database, the construction process of the target tower is judged to be the suspended pole holding process; otherwise, the construction process of the target tower is judged to be the traditional process.

[0040] Stress sensors are installed at key stress-bearing locations on the boom to collect stress at each key stress-bearing location. The maximum stress at the key stress-bearing location is divided by the preset allowable stress to obtain the maximum stress ratio of the boom. Strain gauges are attached to each main material node to collect the strain value of each main material node, from which the maximum strain value of the tower main material is obtained. Stress sensors are installed on the anchor bolts of the tower foundation to measure the reaction forces in various directions. The resultant force is calculated to obtain the horizontal resultant force. The horizontal height of the tower top is collected using a laser displacement meter. The horizontal height of the tower top is multiplied by the horizontal resultant force to obtain the overall overturning moment of the system.

[0041] The environmental data during the construction of the target tower includes wind vibration coefficient, air density, windward area and system mass. The wind vibration coefficient and air density are collected through meteorological parameter monitoring. A BIM model is established based on the construction drawings to obtain the windward area. The weight of each constructed tower component is obtained from the weight of each tower component processed in sections. The weight of each constructed tower component is added together to obtain the system mass.

[0042] In a specific embodiment, the analysis obtains the mechanical response index of each assembly process. The specific analysis process is as follows: the usage frequency of the maximum stress ratio of the holding rod, the usage frequency of the maximum strain value of the tower main material and the usage frequency of the overall overturning moment of the system corresponding to each assembly process are obtained from the database, and substituted into the mechanical response index calculation formula to obtain the mechanical response index of each assembly process, and the assembly process with the maximum mechanical response index is selected as the target assembly process.

[0048] The dynamic correction unit is used to collect abnormal data of construction equipment, construction tower, construction environment and safety monitoring according to the preset optimal lifting sequence and optimal suspension height.

[0049] In a specific embodiment, the specific modules corresponding to the dynamic deviation correction unit include: a hydraulic monitoring module, which is used to collect construction stress data, perform hydraulic compensation control based on the construction stress data, and further collect construction equipment abnormality data.

[0050] The process monitoring module is used to collect the change data of the tilt angle of the holding pole and the change data of the suspension height. According to the change data of the tilt angle of the holding pole and the change data of the suspension height, the construction process is changed, and then the abnormal data of the construction tower is collected.

[0051] Environmental monitoring module, used to collect abnormal data of construction environment.

[0052] The security monitoring module is used to collect abnormal security monitoring data.

[0053] In a specific embodiment, the construction stress data is collected, and the specific collection process is as follows; the construction stress data includes the pressure, pressure stability index, rod internal force and rod internal force stability index corresponding to each hydraulic cylinder currently under construction, the pressure corresponding to each hydraulic cylinder is collected by a pressure sensor, and then the pressure collected each time by each hydraulic cylinder within a preset time is obtained, and the pressure stability index is calculated by the stability index, the rod internal force of each hydraulic cylinder is collected by a strain gauge, and then the rod internal force collected each time by each hydraulic cylinder within a preset time is obtained, and the rod internal force stability index is calculated by the stability index.

[0054] Stability index calculation process: Subtract the difference between the maximum value and the minimum value, and divide it by the sum of the maximum and minimum values to obtain the stability index. For example, subtract the difference between the maximum pressure and the minimum pressure of each hydraulic cylinder within a preset time period and divide it by the sum of the maximum pressure and the minimum pressure to obtain the pressure stability index.

[0055] In a specific embodiment, the hydraulic compensation amount control is specifically generated as follows: according to the optimal lifting sequence, the current construction progress is obtained, and the construction progress correction index corresponding to each construction progress is obtained from the database to obtain the current construction progress correction index, and the pressure, pressure stability index, rod internal force, rod internal force stability index and current construction progress correction index corresponding to each hydraulic cylinder currently under construction are substituted into the hydraulic stability index calculation formula to obtain the hydraulic stability index of each hydraulic cylinder currently under construction.

[0056] It should be noted that the calculation formula of the hydraulic stability index is: ,in is the hydraulic stability index of the hydraulic cylinder a currently under construction, a is the hydraulic cylinder number, and the value of a is a positive integer. 、 、 、 and They are the pressure, pressure stability index, rod internal force, rod internal force stability index and current construction progress correction index corresponding to the hydraulic cylinder a currently under construction. 、 、 and They are respectively the preset standard pressure, standard pressure stability index, standard rod internal force and standard rod internal force stability index. and are the weight factors of the preset pressure and the weight factors of the rod internal force, , , .

[0057] Standard parameters 、 、 and The setup process and standard parameters The setup process is the same as for 1. 1.2, 1.3 and is 1.2, the weight factor and With weight factor The setup process is the same as for is 0.4 and is 0.6.

[0058] Hydraulic compensation control: obtain the standard cylinder hydraulic stability index range from the database. When the hydraulic stability index of a hydraulic cylinder is less than the lower limit of the standard cylinder hydraulic stability index range, increase the hydraulic oil in the cylinder. Obtain the hydraulic oil compensation amount corresponding to each ratio of pressure to rod internal force from the database. The increase in the hydraulic oil in the cylinder is the amount of hydraulic oil corresponding to the ratio of hydraulic cylinder pressure to rod internal force. When the hydraulic stability index of a hydraulic cylinder is greater than the upper limit of the standard cylinder hydraulic stability index range, adjust the pressure distribution of adjacent cylinders.

[0059] In a specific embodiment, the abnormal data of construction equipment is collected, and the specific collection process is as follows: the abnormal data of construction equipment includes the abnormal rate of construction equipment and the abnormal trend index of construction equipment. The number of hydraulic compensation control times within a preset time is collected, and the number of hydraulic compensation control times is divided by the preset time to obtain the abnormal rate of construction equipment, thereby obtaining the abnormal rate of construction equipment collected each time within the preset time, and performing trend index calculation on the abnormal rate of construction equipment within the preset time to obtain the basic abnormal trend index of construction equipment.

[0060] The trend index calculation process is: subtract the difference between the current value and the average value in each collection within the preset time period, and divide it by the difference between the maximum value and the minimum value to obtain the trend index. For example, subtract the difference between the current construction equipment abnormality rate and the average construction equipment abnormality rate within the preset time period, and divide it by the difference between the maximum construction equipment abnormality rate and the minimum construction equipment abnormality rate within the preset time period to obtain the basic abnormality trend index of construction equipment.

[0061] According to the optimal lifting sequence and the current lifting type, the current lifting task progress is obtained, and the task progress correction index corresponding to each lifting task progress and the task type correction index corresponding to each lifting type are obtained from the database to obtain the current task progress correction index and the current task type correction index. The current task progress correction index and the current task type correction index are multiplied to obtain the control frequency correction index. The construction equipment basic abnormal trend index is multiplied by the control basic frequency correction index to obtain the construction equipment abnormal trend index.

[0062] In a specific embodiment, the data on changes in the tilt angle of the pole and changes in the suspension height are collected, and the specific collection process is as follows: the data on changes in the tilt angle of the pole includes the tilt angle deviation rate and the tilt angle deviation trend index of the pole, and the data on changes in the suspension height of the pole includes the maximum change rate of the suspension height of the pole and the suspension height fluctuation rate.

[0063] The tilt angle of the pole is collected using a tilt sensor. The difference between the pole tilt angle and the reference angle is subtracted and divided by the reference angle to obtain the pole tilt angle deviation rate. The pole tilt angle deviation rate collected each time within a preset time period is then obtained. The pole tilt angle deviation rates collected each time within the preset time period are fitted to obtain a curve showing the change of the pole tilt angle deviation rate over time. The slope of the current pole tilt angle deviation rate is obtained using image recognition technology. The trend index corresponding to the slope of each tilt angle deviation rate curve is obtained from a database to obtain the pole tilt angle deviation trend index.

[0064] The suspension height of the pole is measured using a laser rangefinder. The difference in the suspension height measured during each preset holding time is divided by the optimal suspension height to obtain the suspension height change rate measured during each preset holding time. The maximum suspension height change rate is obtained from this value. The suspension height change rates measured during each preset holding time are averaged to obtain the mean suspension height change value. The suspension height fluctuation rate is obtained by subtracting the mean suspension height change value from the maximum suspension height change rate during the preset holding time by dividing the difference between the maximum suspension height change rate and the minimum suspension height change rate.

[0065] In a specific embodiment, the construction process is changed, and the specific change process is as follows: if the tilt angle deviation rate of the holding pole is greater than the preset standard angle deviation rate or the tilt angle deviation trend index is greater than the preset standard tilt angle deviation trend index, it indicates that the tilt angle of the holding pole is abnormal, and the deviation angle of the hanging line between the holding pole and each hanging line is obtained by horizontal modeling, and the direction correction factor corresponding to each hanging line deviation angle and the torque compensation amount corresponding to each tilt angle deviation rate are obtained from the database to obtain the torque compensation amount of the holding pole and the direction correction factor of each hanging line, and the torque compensation amount of the holding pole is multiplied by the direction correction factor of each hanging line to obtain the compensation torque of each hanging line, and the hydraulic system of each hanging line of the holding pole is compensated according to the compensation torque.

[0066] If the maximum change rate of the suspension height of the boom is greater than the preset standard suspension height change rate or the suspension height fluctuation rate is greater than the preset standard suspension height fluctuation rate, it indicates that the suspension height of the boom is abnormal. The height deviation compensation amount corresponding to each suspension height change rate and the compensation time corresponding to each suspension height fluctuation rate are obtained from the database. The height deviation compensation amount is divided by the compensation time to obtain the speed compensation amount of the boom lifting speed. The vertical lifting speed of the boom construction equipment is increased by the speed compensation amount.

[0067] In this way, a plan for changing the construction process is obtained: the hydraulic system of each suspension line of the boom is compensated according to the compensation torque, and the vertical lifting speed of the boom construction equipment increases at a speed equal to the compensation amount.

[0068] In a specific embodiment, the construction tower body abnormality data is collected, and the specific collection process is as follows: the construction tower body abnormality data includes the construction tower body abnormality rate and the construction tower body abnormality trend index, the number of construction process changes within a preset time period is collected, the number of construction process changes is divided by the preset time period, and the construction tower body abnormality rate is obtained, thereby obtaining the construction tower body abnormality rate collected each time within the preset time period, and the construction tower body abnormality rate collected each time within the preset time period is subjected to trend index calculation to obtain the construction tower body abnormality trend index.

[0069] In a specific embodiment, the abnormal construction environment data is collected, and the specific collection process is as follows: the abnormal construction environment data includes the abnormal construction environment rate and the abnormal construction environment trend index. Various types of environmental data are collected through various types of environmental sensors. If the value of a certain type of environmental sensor does not belong to the normal range of the corresponding sensor, it indicates that the environment corresponding to this type of environmental sensor is abnormal. When there is an environmental abnormality in a certain environmental data collection, the collection is recorded as abnormal environmental data collection, so as to obtain the number of abnormal environmental data collections within a preset time, and the number of abnormal environmental data collections is divided by the preset time to obtain the abnormal construction environment rate, and then the abnormal construction environment rate of each collection within the preset time is obtained. The abnormal construction environment rate of each collection within the preset time is calculated as a trend index to obtain the abnormal construction environment trend index.

[0070] It should be noted that various environmental sensors include but are not limited to temperature sensors, humidity sensors, and wind speed sensors.

[0071] In a specific embodiment, the safety monitoring abnormality data is collected, and the specific collection process is as follows: the safety monitoring abnormality data includes the safety monitoring abnormality rate and the safety monitoring abnormality trend index. Various types of environmental data are collected through various types of body health sensors. If the value of a certain type of body health sensor does not belong to the normal range of the corresponding sensor, it indicates that the body safety corresponding to this type of body health sensor is abnormal. When there is a body safety abnormality in a certain body health data collection, the collection is recorded as abnormal safety data collection, so as to obtain the number of abnormal safety data collections within the preset time length, and the number of abnormal safety data collections is divided by the preset time length to obtain the safety monitoring abnormality rate, and then the safety monitoring abnormality rate of each collection within the preset time length is obtained. The safety monitoring abnormality rate within the preset time length is calculated as a trend index to obtain the safety monitoring abnormality trend index.

[0072] It should be noted that various types of physical health sensors include but are not limited to heart rate sensors and blood pressure sensors.

[0073] The project management unit is used to manage the construction project based on abnormal data of construction equipment, abnormal data of construction tower, abnormal data of construction environment and abnormal data of safety monitoring.
