[0012] In order to make the above objects, features and advantages of the present invention more clearly understandable, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0013] During the construction of hydroelectric power projects, cable cranes are important equipment for the construction of concrete arch dams. To ensure the efficient and safe operation of cable cranes, this embodiment of the present invention, based on intelligent construction theory, utilizes network communication technology, Internet of Things technology, high-precision positioning, cross-platform integrated information management, and big data analysis technology to develop intelligent monitoring equipment, project identification models, comprehensive analysis, and phased early warning feedback mechanisms. This establishes an efficient and safe intelligent management and control platform for cable crane groups, and realizes a cable crane intelligent management and control system with real-time monitoring, online analysis, dynamic tracking, and intelligent feedback, thereby effectively improving the efficient and safe operation of cable crane groups. Specifically, the present invention obtains cable crane operation information and monitors the cable crane's usage process in real time based on project identification models, efficiency analysis models, safety analysis models, cable crane efficiency index dynamic calibration models, and early warning management and control models. The corresponding information is output for the administrator to manage the cable crane, thereby realizing early warning of the cable crane's operating status.

[0014] Referring to FIG. 1, an integrated schematic diagram of a cable crane monitoring device according to an embodiment of the present invention is shown. The cable crane monitoring device can be integrated based on a positioning antenna 10, a first communication serial port 11 (e.g., a WIFI serial port), a single-chip microcomputer 12 (e.g., an STM32F103), a cable crane monitoring device-specific technology module 13 (e.g., an M600 module), a ternary lithium power battery 14, and a second communication serial port (e.g., a 4G serial port). Specifically, based on technologies such as satellite differential positioning and Internet of Things communication, a cable crane monitoring device can be developed by integrating satellite positioning, data caching, a large-capacity power supply, and WIFI or 4G communication. The developed cable crane monitoring device can collect information such as the position and speed of the cable crane in real time (e.g., every second), cache the monitoring information, and transmit it to a server in real time via WIFI or 4G communication.

[0015] Referring to FIG. 2, a step flowchart of an embodiment of a cable crane monitoring method according to the present invention is shown, which uses the cable crane monitoring device shown in FIG. 1 and may specifically include the following steps:

[0016] Step 201: Obtain the constant position information of the cable crane, and obtain the material transport process information of the cable crane according to the constant position information through the process identification module.

[0017] The cable crane monitoring device according to an embodiment of the present invention includes a process identification module, an efficiency analysis module, a safety analysis module, a cable crane efficiency index dynamic calibration module, and an early warning management and control module. In practical applications, monitoring the operating status of cable cranes is crucial for large-scale water conservancy projects, especially dam construction processes. Specifically, by constantly acquiring the position information of the cable crane and combining it with a process identification model, an efficiency analysis model, a safety analysis model, and an early warning system, the operating status of the cable crane can be comprehensively monitored and managed.

[0018] Among them, the process identification model is mainly used to identify various important processes in cable crane operation, such as tank stabilization, loading, tank lifting, hoisting, alignment, unloading, and return. The efficiency analysis model is mainly used to analyze the operating efficiency of the cable crane at each process. The safety analysis module is mainly used to monitor whether safety distance requirements are met during cable crane operation. The cable crane efficiency index dynamic calibration model is mainly used to dynamically adjust the cable crane efficiency index based on actual operating data to ensure the accuracy and practicality of the index. The early warning management control model is mainly used to issue early warnings when abnormal situations are detected and take corresponding management control measures.

[0019] In one embodiment of the present invention, the cable crane monitoring device may collect real-time operation information of the cable crane, and the collected operation information may be real-time position information of the cable crane.

[0020] Continuous position information refers to position data of the cable crane at any time throughout the entire process from the start to the end of operation, and for example, this position data may typically include spatial coordinate information and elevation information of the cable crane, as well as associated timestamps.

[0021] The definition of continuous location information can include the following aspects: 1) Real-time location data: At every moment during the cable crane's operation, intelligent monitoring equipment collects the cable crane's current position (x, y, z) and elevation data in real time. 2) Time stamp: Each position data point is accompanied by a time stamp to record the specific time of data collection for subsequent analysis and processing. 3) Continuity: Continuous location information requires continuous data collection, meaning that position data is continuously recorded without interruption throughout the entire cable crane operation process. 4) Completeness: Continuous location information includes all position data of the cable crane from the start of loading to the start of tank drop, covering all material transportation processes, such as tank stabilization, loading, tank lifting, hoisting, alignment, unloading, and return. 5) Accuracy: The accuracy of the location data must be high enough to accurately reflect the cable crane's actual position and elevation, thereby supporting accurate identification of feature values ​​and accurate calculation of process times.

[0022] In other words, by constantly collecting and analyzing location information, the operating status of the cable crane can be comprehensively monitored, problems can be detected and adjusted early, and operational efficiency and safety can be improved.

[0023] In an embodiment of the present invention, the process identification model can identify the material transport process of the cable crane based on the acquired constant position information, acquire material transport process information, and further acquire an efficiency index for evaluating the operating efficiency of the cable crane.

[0024] The material transportation process information identified by the process identification model may include feature value times and process times. The feature value times may be used to define key times and states of the cable crane in various operation stages, and may be primarily used to indicate key times of the cable crane in various operation stages. The process times may be used to understand the time consumed / taken for each stage during the operation of the cable crane, thereby enabling the operational efficiency of the cable crane to be evaluated and monitored based on the aforementioned feature value times and process times.

[0025] Specifically, the process identification model can be used to identify the feature value time of the cable crane based on the constant position information, and then calculate the process time of the cable crane for each material transportation process based on the feature value time of the cable crane. The embodiments of the present invention do not limit the specific process identification process of the process identification model.

[0026] Step 202: Obtain an efficiency index based on the feature value time and / or process time by an efficiency analysis module.

[0027] The efficiency analysis model can be mainly used to analyze the operation efficiency of the cable crane in each process. Specifically, the efficiency analysis model can evaluate and monitor the operation efficiency of the cable crane based on the feature value time and the process time, and obtain an efficiency index for determining the operation efficiency of the cable crane.

[0028] Step 203: The safety analysis module obtains the safety index during the operation of the cable crane.

[0029] The safety analysis module can be mainly used to monitor whether the safety distance requirements are met during the operation of the cable crane. Specifically, the safety analysis model can detect the operation status of the cable crane in real time, and obtain the safety indexes during the operation of the cable crane through analysis.

[0030] Among these, the safety indicator may be a safety distance control indicator, which can be mainly used to indicate whether there is a risk of collision and whether the safety distance requirements are met.

[0031] Step 204: Providing early warning for the operating status of the cable crane based on the efficiency index and the safety distance control index.

[0032] After obtaining an efficiency index for evaluating the operating efficiency of the cable crane and a safety index for evaluating whether the cable crane is at a safe distance, specifically a safety distance control index indicating whether there is a risk of collision and whether the safety distance requirements are met, an early warning can be given about the operating status of the cable crane based on the efficiency index and the safety distance control index.

[0033] For example, monitoring the operating status of the cable crane and providing early warnings can be achieved by setting up a real-time monitoring interface that displays the current position, elevation, time of each characteristic value, and process time of the cable crane. The characteristic value times are monitored, such as the loading start time, loading end time, lifting start time, alignment start time, unloading start time, unloading end time, and tank drop start time, to ensure that the time of each stage is as expected. Also, the time of each process, such as the tank stabilization process, loading process, tank lifting process, lifting process, alignment process, unloading process, and return process, is monitored to ensure that the time of each process is within a reasonable range. This embodiment of the present invention is not limited to this.

[0034] In one embodiment of the present invention, in step 201, the identification of the cable crane material transportation process information can be realized by a process identification module. Specifically, the cable crane material transportation process is shown in Figure 3, which includes processes such as transfer platform, tank drop platform, heavy tank lifting, and no-load return. The feature value times are marked in Figure 3, and ABCDEFG respectively represent the positions of each stage (including time nodes).

[0035] The feature value times may be used to indicate key times for the cable crane during various stages of operation, including, but not limited to, loading start time, loading end time, lifting start time, alignment start time, unloading start time, unloading end time, and tank dropping start time.

[0036] The continuous position information is obtained by detecting the real-time position data of the cable crane. Identifying the feature value time of the cable crane can be expressed as obtaining the real-time position data of the cable crane using a process identification model. Here, the real-time position data includes a plurality of position data points, each of which can be used to indicate the current spatial coordinates and elevation data for each time during the operation of the cable crane. Each position data point (e.g., ABCDEFG in FIG. 3) can be accompanied by a timestamp. In this case, in response to the current spatial coordinates and elevation data indicated by the target position data point satisfying a predetermined condition, the timestamp accompanied by the target position data point can be set as the feature value time of the cable crane.

[0037] For example, after a cable crane moves from the pouring surface to the cable crane platform, if the cable crane's elevation is above the cable crane platform and the cable crane's spatial coordinates (x, y, z) continue to fluctuate within a one-meter range within 1.5 minutes, this means that the current spatial coordinate and elevation data meet the preset condition for position G. In this case, the current time can be defined as the loading start time and is designated T1. After the cable crane begins to depart the cable crane platform, if the cable crane's elevation is still above the cable crane platform but the cable crane's spatial coordinates (x, y, z) continue to fluctuate outside a one-meter range within 1.5 minutes, this means that the current spatial coordinate and elevation data meet the preset condition for position A. In this case, the current time can be defined as the loading end time and is designated T2. If the current spatial coordinate and elevation data match the position where the cable crane leaves the cable crane platform after finishing loading, i.e., position B, the time when the cable crane leaves the cable crane platform after finishing loading can be defined as the lifting start time and is designated T3. After the cable crane moves from the cable crane platform to the pouring surface, if the elevation of the cable crane is lower than the cable crane platform but 30 meters higher than the closing elevation of the pouring bin, it means that the current spatial coordinates and elevation data meet the preset conditions for position C. In this case, the current time can be defined as the positioning start time, which is T4. After the cable crane moves from the cable crane platform to the pouring surface, if the elevation of the cable crane is 2.5 meters lower than the lowest point of the cable crane elevation in this cycle, it means that the current spatial coordinates and elevation data meet the preset conditions for position D. In this case, the current time can be defined as the unloading start time, which is T5.If, after the cable crane moves from the cable crane platform to the pouring surface, the elevation of the cable crane is 2.5 meters lower than the lowest elevation of the cable crane in this cycle, it means that the current spatial coordinates and elevation data meet the set conditions of position E, and the current time can be defined as the unloading end time, which is T6. If the current spatial coordinates and elevation data match the position where the cable crane returns to the cable crane platform range after finishing unloading, that is, position F, the time when the cable crane returns to the cable crane platform range after finishing unloading can be defined as the tank drop start time, which is T7.

[0038] The material transport process includes the tank stabilization process, loading process, tank lifting process, lifting process, positioning process, unloading process, and return process. Process times can be identified by calculating the time difference between the start time of the cable crane tank dropping and the start time of loading to obtain the process time for the cable crane tank stabilization process, i.e., △T1 = T1 - T7. And / or by calculating the time difference between the start time of the cable crane loading and the end time of loading to obtain the process time for the cable crane loading process, i.e., △T2 = T2 - T1. And / or by calculating the time difference between the end time of the cable crane loading and the start time of lifting to obtain the process time for the cable crane tank lifting process, i.e., △T3 = T3 - T2. And / or by calculating the time difference between the start time of the cable crane lifting and the start time of positioning to obtain the process time for the cable crane lifting process, i.e., △T4 = T4 - T3. And / or, calculate the time difference between the start time of the cable crane's positioning and the start time of unloading to obtain the process time for the cable crane's positioning process, i.e., this can be expressed as △T5 = T5 - T4. And / or, calculate the time difference between the start time of the cable crane's unloading and the end time of unloading to obtain the process time for the cable crane's unloading process, i.e., this can be expressed as △T6 = T6 - T5. And / or, calculate the time difference between the end time of the cable crane's unloading and the start time of the tank drop to obtain the process time for the cable crane's return process, i.e., this can be expressed as △T7 = T7 - ​​T6.

[0039] In practical applications, intelligent monitoring equipment can be used to collect real-time cable crane position information, including spatial coordinates (x, y, z) and elevation data. By writing feature values ​​and a process identification algorithm, the algorithm can be implemented through a process identification model to detect and obtain the corresponding feature values. Based on the detected time, the process time can be calculated. A real-time monitoring interface can then be set up to display the cable crane's current position, elevation, the time of each feature value, and the process time.

[0040] In some embodiments of the present invention, the identification of efficiency indicators in step 202 can be achieved by an efficiency analysis module. Specifically, the efficiency analysis of a cable crane is shown in Figure 4. Based on the efficiency evaluation indicators, combined with the real-time analysis information of the cable crane material transportation process, a cable crane efficiency comprehensive analysis model can be established with pre-planning, in-process supervision and management, and post-analysis, which "takes process management control as the core, comprehensive analysis as the conclusion, and indicator calibration as the basis."

[0041] For example, as shown in Figure 4, pre-planning involves the establishment of evaluation criteria, including the setting of process indicators and three-level early warning values ​​(e.g., red, orange, and yellow). Specifically, it involves pre-criteria analysis. Pre-criteria analysis involves establishing a three-level, seven-level process efficiency indicator system for the concrete pouring unit based on the cable crane lifting process. This is combined with factors such as the construction characteristics, resource input, pouring period, and pouring level of similar bins to establish a three-level control indicator threshold for the current bin's pouring efficiency process based on a multi-factor efficiency indicator dynamic calibration model. In-process supervision includes red, hourly, and shift-based process control. Specifically, the concrete pouring unit's evaluation indicator system, combined with real-time analysis data from cable crane monitoring, enables hourly and shift-based abnormal situation analysis and early warning for the cable crane's pouring process, as well as real-time push and message push for major abnormalities. This allows front-line construction personnel, site managers, and rear-line managers to quickly understand the real-time situation of on-site construction. Post-mortem analysis includes comprehensive evaluation, process analysis, identification of abnormalities, and indicator calibration. Specifically, the concrete pouring process can be analyzed from the perspective of overall pouring efficiency and process time consumption, and the progress of the pouring unit and the change trends of key indicators can be comprehensively evaluated and expressed. Processes and equipment showing abnormal pouring efficiency can be accurately identified, and individual construction machines can be analyzed in detail, combined with the on-site construction environment, to analyze the factors affecting efficiency abnormalities and provide reference material for on-site construction management. Preferably, the evaluation indicators of similar dam sections or units can be calibrated in combination with the pouring efficiency of the current bin to provide indicator support for subsequent pouring bins.

[0042] Specifically, the efficiency analysis model can monitor, based on the feature values, whether the timing of each material transport process during cable crane operation is as expected. And / or, based on the process time, whether the process time of each material transport process during cable crane operation is within a reasonable range. And / or, based on the feature value times and the process time, the operational efficiency of each material transport process of the cable crane can be evaluated. For example, feature value times such as the loading start time, loading end time, lifting start time, alignment start time, unloading start time, unloading end time, and tank drop start time can be monitored to confirm that the timing of each stage is as expected. Also, the time of each process such as the tank stabilization process, loading process, tank lifting process, lifting process, alignment process, unloading process, and return process can be monitored to confirm that the time of each process is within a reasonable range. The present invention is not limited to this example.

[0043] In some embodiments of the present invention, identifying the safety distance control indicators in step 203 can be achieved by a safety analysis module. Specifically, cable crane safety analysis is shown in Figure 5, where real-time position information of the cable crane's main tower, sub-tower, and lifting hook can be monitored through intelligent monitoring equipment. By combining the topography of the left and right bank slopes with dam pouring information, the distances between cable cranes, between cable crane and slope, between cable crane and high dam block, and between cable crane and pouring surface equipment can be analyzed in real time to support the safe operation of the cable crane.

[0044] In one embodiment of the present invention, the safety index obtained by analysis using the safety analysis model can be used as a safety distance control index. To obtain the safety distance control index, as shown in Figure 5, the cable crane monitoring device acquires the movement trajectory of the cable crane hook, the position information of the construction machine, the construction pouring surface information, and the high-gradient slope information, and the safety analysis model performs a safety analysis based on the movement trajectory of the cable crane hook, the position information of the construction machine, the construction pouring surface information, and the high-gradient slope information to obtain the safety distance control index.

[0045] Among them, the movement trajectory of the cable crane hook can be used to indicate the real-time positions of the main tower and sub-tower of the cable crane, the position information of the construction machinery can be used to indicate the real-time position of the lifting hook of the cable crane, the construction pouring surface information includes pouring surface design information and pouring progress information, and the high-gradient slope information includes slope coordinate information.

[0046] The basic information includes the movement trajectory of the cable crane hook, the position information of the construction machinery, the construction pouring surface information, the high-gradient slope information, etc. In actual application, the collection of basic information is specifically expressed in the form of obtaining the real-time position information of the cable crane and the construction machinery through the monitoring equipment, inputting the pouring surface design information through the system input function, and then obtaining the pouring elevation information of the dam section from the pouring progress information and the pouring surface design information, and inputting the slope excavation and design information to obtain the slope coordinate information.

[0047] The process of analyzing safety using a safety analysis model and obtaining safety distance control indicators includes real-time analysis of the process, comprehensive analysis, and early warning, as shown in Figure 5. The real-time analysis of the process may include analysis of the cable crane's sway amplitude using a safety analysis model, analysis of the cable crane's operating envelope diagram, analysis of the construction pouring surface elevation and boundary, and 10x10m mesh analysis of high-gradient slopes.

[0048] Specifically, the cable crane sway analysis performed by the safety analysis model can be expressed by constructing the cable crane's main rope straight line based on the real-time positions of the cable crane's main and sub-towers, and then analyzing it using the cable crane's main rope straight line and the real-time position of the cable crane's lifting hook to obtain the cable crane's lifting hook sway value, i.e., the cable crane's lifting hook sway value on a predetermined plane. For example, the cable crane's main rope straight line can be constructed based on the real-time positions of the cable crane's main and sub-towers, and combined with the real-time position of the cable crane's lifting hook, the lifting hook sway value on the xy plane can be analyzed.

[0049] The cable crane operation envelope diagram analysis performed by the safety analysis model can be specifically expressed by constructing a cable crane operation range envelope diagram by the safety analysis model based on the sway amplitude value of the lifting hook of the cable crane and the real-time position of the lifting hook of the cable crane. Illustratively, the cable crane operation range envelope diagram can be constructed by analyzing the real-time position information of the cable crane hook based on the sway amplitude value of the lifting hook of the cable crane.

[0050] The analysis of the elevation and boundary of the construction pouring surface performed by the safety analysis model can be specifically expressed by using the safety analysis model to determine and obtain the pouring start and end elevation information of the current bin based on the pouring progress of each dam section in the pouring progress information, then obtaining the unloading capacity for each strip during the pouring process of the pouring surface from the pouring progress information, and obtaining the current pouring elevation information through obtaining the pouring surface design information and estimating the unloading capacity for each strip. Here, the pouring start and end elevation information can be used to indicate the boundary of the construction pouring surface, and the current pouring elevation information can be used to indicate the elevation of the construction pouring surface. For example, the pouring start and end elevation of the current bin can be determined based on the pouring progress of each dam section, and the current pouring elevation can be estimated in combination with the unloading capacity for each strip during the pouring process of the pouring surface.

[0051] The analysis of high-gradient slope meshing (e.g., 10x10m mesh) performed by the safety analysis model can be expressed by meshing the high-gradient slope using the safety analysis model based on slope coordinate information and a preset cable crane safety distance control strategy to obtain mesh information for the slope. For example, based on the slope coordinates, the slope can be converted into a 10x10m basic mesh in combination with the cable crane safety distance control standard.

[0052] For example, the safety analysis model, i.e., the dam concrete cable crane operation safety analysis model, can be combined with the above process analysis to realize comprehensive analysis, including, but not limited to, analysis of the distance between adjacent cable cranes, analysis of the distance between the unloading point and the boundary of the pouring surface, analysis of the height difference between the cable crane's movement trajectory and the high dam block, analysis of the distance between the cable crane's movement trajectory and a high slope, and analysis of the distance between the unloading point and construction equipment. The embodiments of the present invention are not limited thereto.

[0053] In one embodiment of the present invention, the safety analysis module uses the swing amplitude value of the cable crane lifting hook obtained above to obtain the cable crane operation area envelope diagram, the construction pouring surface elevation and boundary, mesh information for the slope, etc., to perform real-time analysis of the cable crane safety distance and obtain a safety distance control index, thereby realizing real-time analysis of the cable crane safety distance and early warning.

[0054] In practical applications, the safety distance control indicators can be used to indicate whether there is a risk of collision and whether the safety distance requirements are met. The process of comprehensive analysis and early warning, i.e., real-time analysis and early warning of the cable crane's safety distance, is mainly expressed in analyzing and judging whether there is a risk of collision and whether the safety distance requirements are met, and combined with the safety distance control indicators at each stage, provides early warning information prompts to the cable crane operation safety management personnel.

[0055] Specifically, in one example, the safety analysis model may determine the operating area of ​​the cable crane based on the change in the main rope straight line position of the cable crane and the maximum swing value of the cable crane among the swing values ​​of the lifting hook of the cable crane, and use the determined operating area of ​​the cable crane and an envelope diagram of the cable crane operating area to obtain a distance between adjacent cable cranes that can be used to indicate the minimum distance between the boundaries of the operating areas of adjacent cable cranes, and determine whether there is a risk of collision between adjacent cable cranes from the minimum distance between the boundaries of the operating areas of adjacent cable cranes. Illustratively, the operating area of ​​the cable crane can be determined in real time based on the change in the main rope straight line position in combination with the maximum swing width of the cable crane, and the minimum distance between the boundaries of the operating areas of adjacent cable cranes, i.e., the distance between adjacent cable cranes, can be calculated to determine whether there is a risk of collision between adjacent cable cranes.

[0056] As another example, the safety analysis model may determine the position information of the cable crane's lifting and return based on the swing amplitude value of the cable crane's lifting hook, and obtain the distance between the cable crane and the slope through analysis based on the position information of the cable crane's lifting and return and slope coordinate information in the mesh information for the slope, and determine whether there is a risk of collision for the cable crane operating at this altitude from the distance between the cable crane and the slope. Illustratively, by combining the position information of the cable crane's lifting and return with the coordinate information of the slope, the distance between the cable crane and the slope can be analyzed in real time, and it can be determined whether there is a risk of collision for the cable crane operating at this altitude.

[0057] As another example, the safety analysis model may acquire real-time elevation information during the cable crane lifting process and pouring elevation information for each dam section based on the elevation and boundaries of the construction pouring surface, determine the height difference between the cable crane's lifting hook and the high dam block below its operating position based on the real-time elevation information during the cable crane lifting process and the pouring elevation information for each dam section, and determine whether the height difference between the cable crane and the high dam section meets the safety distance requirements from the height difference between the cable crane's lifting hook and the high dam block below its operating position. Illustratively, based on the real-time elevation information during the cable crane lifting process, in combination with the pouring elevation of each dam section, the height difference between the cable crane's lifting hook and the high dam block below its operating position can be determined, and determine whether the height difference between the cable crane and the high dam section meets the safety distance requirements.

[0058] As a further example, the safety analysis model may obtain real-time position information of the cable crane entering the positioning process and coordinate information of the boundary of the pouring surface based on the elevation and boundary of the construction pouring surface, and obtain the horizontal distance between the cable crane and a preset template through analysis based on the real-time position information of the cable crane entering the positioning process and the coordinate information of the boundary of the pouring surface, and determine whether there is a risk of collision between the cable crane and the preset template from the horizontal distance between the cable crane and the template. Illustratively, based on the real-time position information of the cable crane entering the positioning process, the horizontal distance between the cable crane and the template can be analyzed in real time by combining it with coordinate information of the boundary of the pouring surface, and whether there is a risk of collision between the cable crane and the template can be determined.

[0059] As a further example, the safety analysis model may determine the distance between the cable crane and the pouring surface and the construction machine based on position information of the cable crane's positioning process and unloading process, as well as the pouring elevation of the pouring surface and the position information of the construction machine, and determine whether there is a risk of collision between the cable crane and the pouring surface and the construction machine from the distance between the cable crane and the pouring surface and the construction machine. Illustratively, based on the position information of the cable crane's positioning process and unloading process, in combination with the pouring elevation of the pouring surface and the position information of the construction machine, it is possible to determine the distance between the cable crane and the pouring surface and the construction machine, and determine whether there is a risk of collision between the cable crane and the pouring surface and the construction machine.

[0060] In one embodiment of the present invention, the early warning issued in step 204 regarding the operating status of the cable crane can be implemented by an early warning management and control module. Specifically, efficiency and safety indicators can serve as the basis for early warning regarding the operating status of the cable crane. As shown in Figure 6, the efficiency and safety indicators can be used to form a high-efficiency safety management and control indicator system for the cable crane. That is, based on the classification of the cable crane transportation process and the content of safety analysis, the high-efficiency safety operation early warning indicator system for the cable crane group can be divided into two categories, three levels, and 14 indicators.

[0061] In practical applications, to dynamically adjust the cable crane's efficiency index based on actual operating data and ensure the accuracy and practicality of the index, an efficiency index dynamic calibration model must also be used when the early warning management and control model performs early warning analysis. Specifically, the efficiency index dynamic calibration model is used to set the control index threshold for the current bin pouring efficiency process. The early warning management and control model then pushes early warning prompt information to provide an early warning about the cable crane's operating status based on the control index threshold, efficiency index, and safety distance control index. For example, the three-level early warning can be expressed as a yellow threshold, an orange threshold, and a red threshold. Safety indicators may include wind speed in the dam area, cable crane speed, cable crane swing amplitude, cable crane-to-cable crane distance, cable crane-to-slope, cable crane-to-dam block, and cable crane-to-machine. Efficiency indicators may include, but are not limited to, tank stabilization duration, tank lifting duration, loading duration, lifting duration, alignment duration, unloading duration, and return duration.

[0062] In one embodiment of the present invention, specifically, the efficiency reference value of the cable crane is determined by the efficiency index dynamic calibration model, and then, based on the efficiency reference value of the cable crane, control index threshold values ​​divided into predetermined classes are constructed.

[0063] The cable crane efficiency standard can be used to reflect the current efficiency level of each dam section. Its rationality directly affects the accuracy of the Level 3 early warning indicator. Because the cable crane efficiency standard may increase with increases in dam elevation, project management level, construction organization capability, and construction personnel quality, a cable crane efficiency standard calculated using a single historical average or monthly average cannot accurately reflect the current concrete pouring level.

[0064] To determine the efficiency reference value of the cable crane, the efficiency index dynamic calibration model can obtain historical monitoring data and calibrate the efficiency reference value of the cable crane to the historical monitoring data by a division weighting method, and / or the efficiency index dynamic calibration model can calibrate the efficiency reference value of the cable crane by an analogy method of similar dam sections based on the transport distance of the cable crane and the characteristics of the pouring bin of each dam section.

[0065] Referring to Figure 7, a schematic diagram of a dynamic calibration model for cable crane efficiency indicators according to an embodiment of the present invention is shown. The efficiency evaluation index calculation model can achieve the efficiency reference value of a cable crane using an index dynamic inversion analysis method. Specifically, the index dynamic inversion analysis method can be expressed as starting with setting the index using the efficiency evaluation index calculation model, determining whether the bin setting is complex, and calibrating the evaluation index using different division and weighting methods based on different determination results. Here, the division and weighting method can be expressed as a division and weighting method of historical data and an analogy analysis method of similar dam sections.

[0066] As an example, if the determination result indicates that the bin is not complex, a daily (hourly) control index for the pouring surface construction can be calculated, and the control index can be used as an evaluation index. In this case, specifically, a split weighting method for historical data is used. As another example, if the determination result indicates that the bin is complex, a daily (hourly) control index for the pouring surface construction can be calculated, and the control index can be used as an evaluation index. In this case, specifically, a split weighting method for historical data and an analogical analysis method for similar dam sections are used, and this can be expressed by using the evaluation index calculated by the split weighting method for historical data as the historical average value for calculating the evaluation index for the analogical analysis method for similar dam sections. Note that both the split weighting method for historical data and the analogical analysis method for similar dam sections belong to the split weighting method, and both calculation processes involve split weight calculation.

[0067] For example, the historical data split weighting method can be expressed by calibrating the efficiency reference value of the cable crane using the split weighting method based on historical monitoring data, using the formula: Index Value = Monitoring Bin Average Value × 0.2 + Historical Average Value × 0.2 + Historical Optimal Value × 0.2 + Past Three Months Average Value × 0.4, thereby accurately reflecting the current cable crane concrete driving efficiency level. Here, the monitoring bin average value refers to the current or latest average value, the historical average value refers to the average value at a predetermined time in the past, the historical optimal value refers to the optimal value at a predetermined time in the past, and the past three months average value refers to the average value for the past three months. 0.2 and 0.4 refer to the weights of the corresponding variables. Specific weights may be determined according to actual needs or through experiments, but the embodiments of the present invention are not limited thereto.

[0068] The analogy method for similar dam sections can be expressed by calibrating the cable crane efficiency reference value using the analogy method for similar dam sections according to the cable crane's transport distance and the characteristics of the concrete pouring bins for each dam section. The formula is: Index Value = Monitoring Bin Average Value × 0.2 + Historical Average Value × 0.2 + Optimal Value of Similar Concreting Surface × 0.2 + Average Value of Similar Concreting Surface × 0.4. This accurately reflects the transport efficiency of special dam sections, such as those with different transport distances and complex concrete pouring surfaces (middle holes, bottom holes). Here, the monitoring bin average value refers to the current or most recent average value, the historical average value refers to the average value at a given time in the past, the optimal value of similar concrete pouring surfaces refers to the optimal value of other concrete pouring surfaces similar to the current situation, and the average value of similar concrete pouring surfaces refers to the average value of other concrete pouring surfaces similar to the current situation. 0.2 and 0.4 refer to the weights of the corresponding variables. The specific weights may be determined based on actual needs or experiments, but the present invention is not limited thereto.

[0069] Optionally, when establishing control indicator thresholds divided into predetermined grades based on the cable crane efficiency reference value, first, second, and third grade preset control indicator thresholds can be established based on the cable crane efficiency reference value, where the first grade preset may be higher than the second grade preset, and the second grade preset may be higher than the third grade preset. For example, the first grade preset control indicator threshold may be a red early warning indicator value, the second grade preset control indicator threshold may be an orange early warning indicator value, and the third grade preset control indicator threshold may be a yellow early warning indicator value. That is, based on the established three grades of yellow, orange, and red early warning indicator values, the cable crane operation efficiency value is calculated every hour according to the seasonal, day / night shift, and hourly variation rules of the cable crane transportation efficiency to precisely reflect the cable crane transportation efficiency level, thereby realizing detailed setting and management control of the cable crane indicators. The embodiments of the present invention are not limited in this regard.

[0070] Dam construction involves many construction personnel and has a complex personnel structure. To meet the requirements for efficient and safe management and control of cable crane groups, an early warning management and control model for cable crane operation can be established. Specifically, when the efficiency index and safety distance control index reach a predetermined control index threshold corresponding to the first level, early warning prompt information is sent in a timely manner. When the efficiency index and safety distance control index reach a predetermined control index threshold corresponding to the second level, early warning prompt conditions are sent periodically. When the efficiency index and safety distance control index reach a predetermined control index threshold corresponding to the third level, early warning prompt information such as a shift early warning can be sent collectively.

[0071] Referring to FIG. 8, a schematic diagram of an operation early warning management control module of a cable crane according to an embodiment of the present invention is shown. The cable crane operation early warning management control module is specifically represented as an early warning feedback module, and relates to process management control and comprehensive evaluation process.

[0072] For example, in process management control, early warnings can be provided by combining the analysis results of cable crane efficiency and safety with third-level early warning indicators. For example, red early warning information can be pushed in a timely manner to enable timely corrections on-site and achieve immediate early warnings. Statistics on the operation status of the cable crane group, including yellow, orange, and hourly, can be pushed, allowing all construction personnel to quickly understand the construction status on-site and achieving hourly and shift-specific early warnings. Personnel responsible for pushing messages include on-site construction workers, site supervisors, on-site production office managers, rear-office managers, and leadership (e.g., construction department leaders, supervision department leaders, etc.). While the pushing method is primarily via a mobile app, embodiments of the present invention are not limited to this.

[0073] The comprehensive evaluation process analyzes the overall operation of the cable crane in combination with the on-site construction status, accurately pinpointing and analyzing abnormal cable crane operation and identifying the main influencing factors. The results are reported to the owner, designer, supervisor, and construction personnel for analysis to serve as a reference for subsequent construction. For example, the comprehensive evaluation of cable crane operation may include efficiency evaluation, abnormality analysis, utilization rate, and safety analysis. After the comprehensive evaluation of cable crane operation, the evaluation results can be comprehensively evaluated by three parties, which may include the leader and construction personnel.

[0074] The embodiments of the present invention are not limited to these.

[0075] In an embodiment of the present invention, the cable crane monitoring device acquires continuous position information of the cable crane, the process identification module acquires material transport process information of the cable crane based on the continuous position information, the acquired material transport process information may include characteristic value time and process time, the efficiency analysis module further obtains an efficiency index based on the characteristic value time and / or process time, and the safety analysis module acquires a safety index for the cable crane during operation, the safety index may be a safety distance control index, which is mainly used to indicate whether there is a collision risk and whether safety distance requirements are met, thereby facilitating early warning of the cable crane operation status based on the efficiency index and safety distance control index obtained by the analysis. The cable crane's continuous position information is acquired, and the process identification module, efficiency analysis module, and safety analysis module monitor the cable crane's use process in real time, and corresponding information is output for the manager to manage the cable crane, thereby achieving early warning of the cable crane operation status.

[0076] To make it easier for those skilled in the art to understand the cable crane monitoring method proposed in the embodiments of the present invention, the embodiments of the present invention will be described below in combination with application scenarios of cable crane monitoring.

[0077] Referring to Figure 9, a schematic diagram of an application scenario for cable crane monitoring according to an embodiment of the present invention is shown. The cable crane monitoring solution according to an embodiment of the present invention can be mainly implemented on an intelligent management and control platform for safe dam concrete construction. The intelligent management and control platform for safe dam concrete construction can be a digital platform.

[0078] In a dam concreting project, the safety construction intelligent management and control platform controls the cable crane monitoring equipment and comprehensively monitors the cable crane's operating status. Specifically, it uses a process identification model to automatically identify the current process of the cable crane, an efficiency analysis module to calculate the efficiency index of each process, a safety analysis model to monitor potential safety risks, a cable crane efficiency index dynamic calibration model to dynamically adjust the efficiency index, and an early warning management and control model to issue early warnings in a timely manner when abnormal situations are detected. The comprehensive use of these models ensures the efficient and safe operation of the cable crane and ensures the smooth progress of the dam concreting project.

[0079] The safe construction intelligent management and control platform can display display interfaces for information such as cable crane safety, cable crane material transportation process, pouring quality, transportation strength, pouring strength, transportation efficiency, and efficiency early warning.

[0080] For example, in a certain dam construction project, an elliptical concrete double curvature arch dam was adopted, with a dam top elevation of 834.00 m, a maximum dam height of 289.0 m, and a total volume of approximately 8.1 million m. 3 The dam body has horizontal joints but no vertical joints, and is divided into 31 dam sections. The peak construction month design strength is 236,300m 3Assume that there are a total of seven cable crane groups, arranged in two levels. The elevated cable cranes have a main track length of 310m and a maximum span of 1,186.756m, while the low-level cable cranes have a main track length of 245m and a maximum span of 1,110.49m. Strong winds blow throughout the dam valley, with a maximum wind speed of 29.8m / s. In this case, the operation of the cable crane groups is managed and controlled through the intelligent management and control platform for safe dam concrete construction. The large-screen display of the high-efficiency and safe dam concrete construction digital management and control system throughout the entire process can be used to monitor key efficiency and safety indicators in real time. Mobile monitoring can also be achieved through the monitoring and early warning platform.

[0081] Taking other operational disturbances that affect the operational efficiency of cable cranes as an example, the efficiency analysis table for cable cranes is shown in Table 1.

[0082] Table 1 Cable crane efficiency analysis table JPEG2026035527000002.jpg61155

[0083] From the above, it was found that the site conditions for the first three weeks exceeded the standard values. In this case, the joint investigation revealed that the construction of the cable crane platform blocked the passage for transport vehicles, causing the cable crane to wait for 1-2 minutes to deliver materials. In this case, it was suggested that a dedicated passage be set up for transport vehicles to minimize the impact on the dam's concrete pouring efficiency. Verification and analysis in the fourth week showed that the time required for material delivery had been significantly reduced, and the overall concrete pouring efficiency had been greatly improved.

[0084] This embodiment of the present invention introduces a new approach to the industrial Internet, adopting technologies such as the Internet of Things (IoT), sensors, and big data to propose a cable crane analysis and management control system that incorporates management and control targets, evaluation indicators, dynamic management and control, and comprehensive evaluation. This is a new type of hydropower engineering construction system that fully integrates all elements, the entire industrial chain, and the entire value chain. A highly efficient and safe intelligent management and control platform for cable crane groups is developed that integrates intelligent monitoring, real-time analysis, feedback early warning, and dynamic tracking. Using large-screen systems, mobile apps, and smart terminals, it achieves multi-dimensional collaborative management and control encompassing owners, designers, supervisors, construction, and scientific research departments, thereby addressing the shortcomings of construction management, such as the difficulty of supervision, coordination, and tracking. Although research on intelligent construction of hydropower projects in China has achieved some success, many difficulties and challenges remain to be overcome in the precise management and control of the entire concrete dam construction process. Close integration with the needs of project construction, deep exploration, and innovation are necessary. The continuous maturation of emerging technologies such as the Beidou positioning system, engineering digital construction technology, big data technology, and new infrastructure, as well as the continuous deepening of research into intelligent analysis and control technology in the hydropower industry, will promote the sustainable development of intelligent dam construction technology in China and, ultimately, the world.

[0085] To ensure the efficient and safe operation of cable cranes, this embodiment of the present invention, based on intelligent construction theory, uses network communication technologies, Internet of Things technologies, high-precision positioning, cross-platform integrated information management, and big data analysis technologies as means to research intelligent monitoring equipment, project identification models, comprehensive analysis, and staged early warning feedback mechanisms to build an efficient and safe intelligent management and control platform for cable crane groups, and realizes a cable crane intelligent management and control system with real-time monitoring, online analysis, dynamic tracking, and intelligent feedback, thereby effectively improving the efficient and safe operation of cable crane groups. Specifically, the present invention obtains cable crane operation information and, based on project identification models, efficiency analysis models, safety analysis models, cable crane efficiency index dynamic calibration models, and early warning management and control models, monitors the cable crane usage process in real time and outputs corresponding information for managers to manage the cable crane, thereby realizing early warning of the cable crane's operating status.
