Description

Technical Field

[0001] This application relates to the technical field of project monitoring, and specifically relates to a monitoring method, system, electronic device and storage medium for project construction. Background Art

[0002] With the development of technology, the scale of construction projects has been continuously expanding, and the complexity of building structures and construction techniques has also increased significantly. This has led to the fact that construction sites are often dangerous, and safety accidents are likely to occur when construction workers are not at their posts. At the same time, if construction workers are away from their posts for a long time, it is easy to slow down the construction progress. Therefore, it is necessary to monitor construction workers.

[0003] Currently, mainly safety officers conduct inspections to check whether construction workers are at their posts. However, this method is too inefficient and it is difficult to cover every place on the construction site.

[0004] Therefore, a method that can efficiently monitor whether construction workers are on duty is needed. Summary of the Invention

[0005] This application provides a monitoring method, system, electronic device and storage medium for project construction, which can monitor in real time whether construction workers are on duty, and can determine whether the action trajectory of a construction worker is abnormal according to the action trajectory outside the preset working range of the construction worker.

[0006] In the first aspect of this application, a monitoring method for project construction is provided, which is applied to a remote monitoring platform. The method includes:

[0007] Obtain the target position of a construction worker through the interaction between a fixed beacon and a wireless communication module. The fixed beacon is set at the construction site, and the wireless communication module is carried by the construction worker. Determine whether the target position is within the preset working range of the construction worker;

[0008] When the target position is not within the preset working range of the construction worker, determine whether the target position is within a preset danger range;

[0009] When the target position is not within the preset danger range, obtain the action trajectory of the construction worker, count the total duration of the sub-action trajectory, and determine whether the total duration is greater than a threshold value. The sub-action trajectory is the action trajectory outside the preset working range;

[0010] When the total duration is greater than the threshold value, determine that the action trajectory of the construction worker is abnormal and send a warning to the management personnel.

[0011] By adopting the above technical solutions, based on the interaction between the fixed beacon and the wireless communication module, the target position of the construction worker can be obtained in real time, and then it can be determined whether the worker is within the preset working range. This helps to promptly detect the situation where construction workers may leave the safe area due to misoperation or negligence, so as to take necessary warning or intervention measures to prevent safety accidents. By monitoring the movement trajectory of construction workers and counting the total duration of sub-movement trajectories, the activities of construction workers in non-working areas can be analyzed. When the total duration exceeds the preset threshold, it can be determined that the movement trajectory of the construction worker is abnormal, which may mean that the construction worker has unnecessary walking or time-wasting behaviors. By optimizing these behaviors, the construction efficiency can be improved and unnecessary resource consumption can be reduced. By monitoring the positions and movement trajectories of construction workers, managers can more clearly understand the actual situation of the construction site, including personnel distribution, work processes, etc. This helps to promptly discover and solve order problems during the construction process and ensure that the construction proceeds according to the established plan and process. When applied to a remote monitoring platform, it enables managers to grasp the positions and movement conditions of construction workers in real time without having to go to the construction site in person. This greatly improves the convenience and flexibility of management, especially for large and complex construction projects, which has significant advantages. When the target position of the construction worker is within the preset dangerous range, the remote monitoring platform can immediately issue a warning to notify the manager to take corresponding emergency measures. This timely warning and response mechanism helps to reduce the risk and losses of safety accidents.

[0012] Optionally, obtaining the target position of the construction worker through the interaction between the fixed beacon and the wireless communication module includes:

[0013] Obtaining the first signal transmission time between the first fixed beacon and the wireless communication module, obtaining the second signal transmission time between the second fixed beacon and the wireless communication module, and obtaining the third signal transmission time between the third fixed beacon and the wireless communication module;

[0014] Calculating the first distance between the first fixed beacon and the wireless communication module according to the first signal transmission time, calculating the second distance between the second fixed beacon and the wireless communication module according to the second signal transmission time, and calculating the third distance between the third fixed beacon and the wireless communication module according to the third signal transmission time;

[0015] Determining the target position of the construction worker corresponding to the wireless communication module according to the first distance, the second distance, and the third distance.

[0016] By adopting the above technical solution, the signal transmission time between multiple fixed beacons and the wireless communication module can be obtained, and the distance between each fixed beacon and the wireless communication module can be calculated. This distance measurement based on multiple points can more accurately determine the position of the wireless communication module (i.e., the construction worker). Compared with a single positioning method, this multi-point positioning method reduces the positioning error and improves the positioning accuracy. Using at least three fixed beacons for positioning can achieve precise positioning of the construction worker's position in three-dimensional space. This means that not only can the position of the construction worker on the plane be determined, but also their height information can be determined, which is particularly important at the construction site of multi-story or three-dimensional structures. Since the acquisition of the signal transmission time is real-time, the target position of the construction worker is also updated in real-time. This ensures that the monitoring platform can grasp the dynamic position information of the construction worker in real-time, which is crucial for timely discovering and handling safety issues. Based on the interaction between the fixed beacon and the wireless communication module, the fixed beacon can be flexibly arranged according to the actual situation of the construction site. If it is necessary to expand the monitoring range or improve the positioning accuracy, it can be achieved by increasing the number of fixed beacons or optimizing their layout. By accurately obtaining the target position of the construction worker, the monitoring platform can more efficiently determine whether the construction worker is within the preset working range, whether they are in a dangerous area, and whether their movement trajectory is abnormal. This helps to reduce false alarms and missed alarms and improve the monitoring efficiency.

[0017] Optionally, the obtaining of the movement trajectory of the construction worker and the statistics of the total duration of the sub-movement trajectories include:

[0018] Obtain the target position of the construction worker and the corresponding timestamp, and connect all the target positions to form a movement trajectory;

[0019] Determine all the target positions that are not within the preset working range, and connect all the target positions that are not within the preset working range to form a sub-movement trajectory;

[0020] Determine the sub-time periods when leaving the preset working range in the sub-movement trajectory according to the timestamp, and add up all the sub-time periods to obtain the total duration of the sub-movement trajectory.

[0021] By adopting the above technical solution, the target position of the construction personnel and the corresponding timestamp can be obtained, and the movement trajectory of the construction personnel can be formed. Such a visualized trajectory enables the management personnel to intuitively understand the movement of the construction personnel at the construction site, facilitating the traceability and analysis of the construction process. Determining and extracting all target positions outside the preset working range to form a sub-movement trajectory helps the management personnel focus on analyzing the activities of the construction personnel in the non-working area. This helps to discover problems such as unauthorized absence from work, illegal operations, or frequent entry into dangerous areas by the construction personnel. By determining the sub-time period when leaving the preset working range in the sub-movement trajectory through the timestamp and counting the total duration of these sub-time periods, the activity time of the construction personnel in the non-working area can be quantitatively analyzed. This analysis in the time dimension helps to evaluate the work efficiency and standardization of the construction personnel, as well as to discover potential safety hazards. When the total duration of the sub-movement trajectory exceeds the preset threshold, it can be determined that the movement trajectory of the construction personnel is abnormal. The identification of such abnormal behavior helps to timely discover and handle potential safety problems and prevent accidents. Through the analysis of the movement trajectory of the construction personnel, the management personnel can understand the actual activities of the construction personnel at the construction site, thereby optimizing the construction plan and resource allocation. For example, according to the activity range and time of the construction personnel, the construction tasks can be reasonably arranged, and the equipment and materials can be allocated to improve the construction efficiency.

[0022] Optionally, the counting of the total duration of the sub-movement trajectory includes:

[0023] Judging whether the first position in the sub-time period is within the preset rest range. When the first position is not within the preset rest range, the sub-time period is determined as the first sub-time period. When the first position is within the preset rest range, the sub-time period is determined as the second sub-time period. Adding up all the first sub-time periods gives the total duration of the sub-movement trajectory.

[0024] Wherein, the first position and the second position are any two positions in the sub-movement trajectory, and the first distance between the first position and the geometric center of the preset working range is greater than the second distance between the second position and the geometric center of the preset working range.

[0025] By adopting the above technical solution, it is possible to determine whether the first position in the sub-time period is within the preset rest range, and exclude the rest time of the construction workers from the total duration. This helps to more accurately count the effective working time of the construction workers in the non-working area, and avoid the problem of the total duration being too long due to the rest time being miscounted. By distinguishing the first sub-time period (the sub-time period not within the rest range) and the second sub-time period (the sub-time period within the rest range), it is possible to more accurately evaluate the impact of the activities of the construction workers in the non-working area on work efficiency. This helps the management to identify and improve the behaviors or processes that may lead to reduced efficiency. By accurately counting the total duration of the sub-action trajectory, the management can more accurately understand the activities of the construction workers in the non-working area, so as to optimize resource allocation and scheduling. For example, other tasks can be reasonably arranged or personnel can be replaced according to the rest time of the construction workers to ensure the continuity and efficiency of the construction process. Through this refined data collection and analysis, the management can make more scientific and reasonable decisions based on actual data. For example, the division of the working area or the arrangement of the rest time can be adjusted according to the activity patterns of the construction workers to improve the overall construction efficiency and safety.

[0026] Optionally, the statistics of the total duration of the sub-action trajectory include:

[0027] Determine the action trajectories with personnel overlap based on the action trajectories of all construction workers, count the number of construction workers appearing in each overlapping action trajectory, and determine the time coefficient corresponding to each overlapping action trajectory according to the number, where the time coefficient is inversely proportional to the number;

[0028] Calculate the total duration of the sub-action trajectory according to the time coefficient.

[0029] By adopting the above technical solution, the action trajectories with personnel overlap are determined, and the number of people in each overlapping trajectory is counted, which can more truly reflect the actual activities and work efficiency of construction workers in non-working areas. The time coefficient is introduced as an adjustment factor, and the time weight of each trajectory is determined according to the number of people in the overlapping trajectory. The time coefficient is inversely proportional to the number of people, which means that when the number of people is large, the effective working time of each person may be reduced, so the time contribution of this trajectory is correspondingly reduced. This optimized time statistics method can more accurately reflect the actual working time of construction workers in non-working areas. By considering the overlap of action trajectories, the utilization of construction resources can be evaluated more accurately. For example, when multiple construction workers appear in the same area at the same time, there may be a situation of resource sharing or collaboration, which does not necessarily mean a waste of resources. By introducing the time coefficient, the effective utilization degree of construction resources can be evaluated more objectively. According to the analysis results of the overlapping action trajectories and the time coefficient, managers can more pertinently guide the construction organization and scheduling work. For example, for areas where personnel overlap frequently, the construction plan can be optimized to avoid too many people appearing in the same area at the same time and improve construction efficiency. By collecting and analyzing the action trajectory data of construction workers and combining the adjustment of the time coefficient, data-driven decision-making support can be provided for managers. Based on these data, managers can formulate more scientific and reasonable construction plans and management measures to improve the overall efficiency and safety of the construction site.

[0030] Optionally, the calculating the total duration of the sub-action trajectory according to the time coefficient includes:

[0031] Determine the overlapping action trajectories and non-overlapping action trajectories in the sub-action trajectory, perform weighted summation on the time coefficient corresponding to the overlapping action trajectory and the corresponding third sub-time period to obtain a fifth sub-time period, and add the fifth sub-time period to the fourth sub-time period to obtain the total duration of the sub-action trajectory, where the third sub-time period refers to the time period corresponding to the overlapping action trajectory, and the fourth sub-time period refers to the time period corresponding to the non-overlapping action trajectory.

[0032] By adopting the above technical solution, overlapping action trajectories and non-overlapping action trajectories are distinguished, and the corresponding time periods are processed separately, so that the activity time of construction workers in non-working areas can be counted more accurately. Overlapping action trajectories may involve multiple people sharing time or space, while non-overlapping action trajectories represent the activity time of individual construction workers. This distinction helps to avoid double counting or omission and improve the accuracy of time statistics. A time coefficient is introduced as a weighting factor to adjust the time period corresponding to the overlapping action trajectory. The time coefficient is inversely proportional to the number of people in the overlapping trajectory, which reflects the possible reduction in efficiency when multiple people work simultaneously. By weighted summation, the actual work efficiency of construction workers in the overlapping action trajectory can be more realistically reflected. By analyzing the distribution and duration of overlapping action trajectories and non-overlapping action trajectories, managers can better understand the resource utilization situation at the construction site. This helps to optimize resource allocation, avoid resource waste, and improve construction efficiency. Based on the analysis results of overlapping action trajectories and non-overlapping action trajectories, managers can carry out construction management more targeted. For example, for areas where overlapping action trajectories frequently occur, the construction plan can be optimized to reduce personnel aggregation and improve construction safety; for construction workers with longer non-overlapping action trajectories, their work habits can be concerned, and necessary support and guidance can be provided. By accurately calculating and analyzing the total duration of sub-action trajectories, managers can make more scientific and reasonable decisions based on actual data. For example, the working time arrangement can be adjusted according to the activity time distribution of construction workers, the construction plan can be optimized, and the construction efficiency and quality can be improved.

[0033] Optionally, the method further includes:

[0034] When the target position is within a preset dangerous range, the identity of the construction worker is determined through the wireless communication module,

[0035] Judge whether the construction worker has the permission to enter the preset dangerous range according to the identity;

[0036] When the construction worker does not have the permission to enter the preset dangerous range, prompt the manager that an abnormality has occurred within the preset dangerous range.

[0037] By adopting the above technical solutions, the target positions of construction workers are monitored in real time. Once it is detected that a construction worker enters the preset dangerous range, the remote monitoring platform can respond immediately. This helps to promptly discover and handle potential safety hazards, thereby significantly enhancing the safety of the construction site. A judgment mechanism for the permissions of construction workers is introduced. When a construction worker enters a dangerous area, the remote monitoring platform will check whether they have the corresponding permissions. This way of permission management can ensure that only authorized personnel can enter specific areas, further strengthening the safety management of the construction site. When it is detected that a construction worker without permission enters the dangerous range, the remote monitoring platform will immediately prompt the management personnel, enabling the management personnel to quickly understand and handle abnormal situations. This real-time feedback mechanism helps the management personnel to respond promptly and prevent potential safety accidents from occurring. Through the automated permission judgment and abnormal prompt functions, the need for the management personnel to monitor the construction site in real time can be reduced, thereby reducing the work intensity and improving the work efficiency. At the same time, the automated management method also helps to reduce human errors and oversights and improve the management quality. The remote monitoring platform can record each event of a construction worker entering the dangerous range, including information such as the identity of the construction worker and the timestamp. This provides strong data support for subsequent safety accident investigations and liability tracing.

[0038] In the second aspect of the present application, a monitoring system for project construction is provided, including a position module, a judgment module, a trajectory module, and a judgment module, where:

[0039] The position module is configured to obtain the target position of a construction worker through the interaction between a fixed beacon and a wireless communication module. The fixed beacon is set at the construction site, and the wireless communication module is carried by the construction worker, and determine whether the target position is within the preset working range of the construction worker;

[0040] The judgment module is configured to, when the target position is not within the preset working range of the construction worker, determine whether the target position is within the preset dangerous range;

[0041] The trajectory module is configured to, when the target position is not within the preset dangerous range, obtain the action trajectory of the construction worker, count the total duration of the sub-action trajectory, and determine whether the total duration is greater than a threshold. The sub-action trajectory is the action trajectory that is not within the preset working range;

[0042] The judgment module is configured to, when the total duration is greater than the threshold, determine that the action trajectory of the construction worker is abnormal and issue a warning to the management personnel.

[0043] In a third aspect of the present application, an electronic device is provided, including a processor, a memory, a user interface, and a network interface. The memory is used to store instructions, both the user interface and the network interface are used to communicate with other devices, and the processor is used to execute the instructions stored in the memory, so that the electronic device executes the method described in any one of the above.

[0044] In a fourth aspect of the present application, a computer-readable storage medium is provided. The computer-readable storage medium stores instructions, and when the instructions are executed, the method described in any one of the above is executed.

[0045] In summary, one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0046] 1. Through the interaction between the fixed beacon and the wireless communication module, the target position of the construction worker can be obtained in real time, so as to realize the real-time monitoring of the construction site. When the target position of the construction worker is not within the preset working range, the remote monitoring platform can immediately perceive and make corresponding judgments to ensure timely early warning and response.

[0047] 2. The preset danger range is particularly considered. When the target position of the construction worker enters this range, the remote monitoring platform can quickly identify and make corresponding treatments, effectively preventing potential safety accidents. This special monitoring mechanism for dangerous areas significantly enhances the safety of the construction site.

[0048] 3. When the target position of the construction worker is not within the preset working range and not within the preset danger range, the remote monitoring platform will further obtain its action trajectory and count the total duration of the sub-action trajectory. This analysis helps to understand the activities of the construction worker in the non-working area, evaluate its impact on work efficiency, and provide a basis for optimizing the construction plan and resource allocation.

[0049] 4. By comparing the total duration of the sub-action trajectory with the preset threshold, the remote monitoring platform can identify the abnormal action trajectory of the construction worker. This abnormal identification mechanism helps to timely discover and handle potential problems, preventing safety accidents or work delays caused by the illegal behavior or negligence of the construction worker.

[0050] 5. Based on real-time data and a series of logical judgments, data-driven decision support is provided for managers. Managers can make more scientific and reasonable decisions according to the real-time information and early warnings provided by the system, improving the management level and efficiency of the construction site.

[0058] This embodiment discloses a method for monitoring project construction, Figure 1 It is a schematic flow diagram of a method for monitoring project construction disclosed in an embodiment of the present application. As Figure 1 shown, the monitoring method includes the following steps:

[0059] S110. Obtain the target position of the construction worker through the interaction between the fixed beacon and the wireless communication module. The fixed beacon is set at the construction site, and the wireless communication module is carried by the construction worker. Determine whether the target position is within the preset working range of the construction worker.

[0060] A fixed beacon is a device specifically designed to provide continuous and stable signal transmission at a specific location. It can be evenly installed at the construction site and communicate with the wireless communication module carried by the construction worker through a wireless signal. The fixed beacon determines the distance between the fixed beacon and the wireless communication module by sending a signal to the wireless communication module and receiving the signal returned by the wireless communication module. The wireless communication module is usually designed to be lightweight and durable and can be carried by the construction worker or set inside the construction worker's safety helmet. The interaction between the fixed beacon and the wireless communication module is real-time. They establish a connection through a wireless network to transmit and receive information. Multiple beacons are used in combination to determine the specific position of the construction worker and upload the position information to the remote monitoring platform. The remote monitoring platform can judge whether the construction worker is within the preset working range based on the received position information, and then take corresponding measures to ensure the safety and efficiency of the construction site. The target position in the embodiments of the present application may refer to the position at the current moment.

[0061] Optionally, the obtaining the target position of the construction worker through the interaction between the fixed beacon and the wireless communication module includes:

[0062] Obtain the first signal transmission time between the first fixed beacon and the wireless communication module, obtain the second signal transmission time between the second fixed beacon and the wireless communication module, and obtain the third signal transmission time between the third fixed beacon and the wireless communication module.

[0063] Calculate the first distance between the first fixed beacon and the wireless communication module according to the first signal transmission time, calculate the second distance between the second fixed beacon and the wireless communication module according to the second signal transmission time, and calculate the third distance between the third fixed beacon and the wireless communication module according to the third signal transmission time.

[0064] Determine the target position of the construction worker corresponding to the wireless communication module according to the first distance, the second distance, and the third distance.

[0065] Obtain the first signal transmission time between the first fixed beacon and the wireless communication module. The first signal transmission time refers to the time period from the moment when the first fixed beacon sends a signal to the wireless communication module until the moment when the wireless communication module returns the signal is received. Calculate the first distance between the first fixed beacon and the wireless communication module based on the first signal transmission time and the wireless signal transmission speed (generally the speed of light). Similarly, the second distance and the third distance between the second fixed beacon and the third fixed beacon and the wireless communication module can be obtained respectively. Since the coordinates of the first fixed beacon, the second fixed beacon, and the third fixed beacon are known, and the distances between the first fixed beacon, the second fixed beacon, and the third fixed beacon and the wireless communication module have been calculated, the accurate location of the wireless communication module can be calculated by the method of trilateration, that is, the target position of the construction worker can be calculated.

[0066] By the real-time interaction between the fixed beacon and the wireless communication module, the target position of the construction worker can be obtained in real time. This is crucial for project construction that requires real-time knowledge of the location and dynamics of construction workers, and helps managers make decisions and adjustments in a timely manner. Using the principle of trilateration and combining the distance information between three fixed beacons and the wireless communication module, the target position of the construction worker can be accurately calculated. This positioning method has higher accuracy and reliability compared to single-beacon positioning and can meet the requirement of accurately knowing the position of construction workers. By obtaining the target position of the construction worker in real time, it can be determined whether the worker is within the preset working range. Once the construction worker deviates from the working area or enters a dangerous area, the remote monitoring platform can immediately trigger the warning mechanism to remind the manager to take safety measures in a timely manner, thus ensuring the safety of the construction worker. The real-time positioning of construction workers helps to optimize the resource allocation and scheduling at the construction site. Managers can reasonably arrange work tasks and resource allocation according to the distribution of construction workers, improving construction efficiency.

[0067] S120. When the target position is not within the preset working range of the construction worker, determine whether the target position is within the preset dangerous range;

[0068] The preset working range can be set according to the work content of the construction personnel, and the preset danger range can be set according to the specific conditions and safety requirements of the construction site. The preset danger range may include areas near heavy mechanical equipment, the edges of deep foundation pits, and near high-voltage wires. Each preset working range and preset danger range is delimited by precise coordinates or boundary lines and stored in the database of the remote monitoring platform. When the remote monitoring platform discovers through the interaction between the fixed beacon and the wireless communication module that the target position of a certain construction personnel is not within its preset working range, the remote monitoring platform will immediately trigger a further judgment mechanism. The remote monitoring platform will first obtain the real-time target position coordinates of the construction personnel, and then compare them with the preset danger range stored in the database to determine whether the target position is within the preset danger range.

[0069] Optionally, the method further includes:

[0070] When the target position is within the preset danger range, determine the identity of the construction personnel through the wireless communication module,

[0071] Judge whether the construction personnel has the permission to enter the preset danger range according to the identity;

[0072] When the construction personnel do not have the permission to enter the preset danger range, prompt the management personnel that there is an abnormality within the preset danger range.

[0073] In the preset dangerous range, usually only people with specific skills are allowed to enter. The remote monitoring platform will grant corresponding permissions to these people and store them in the database of the remote monitoring platform. If the target position coordinates of the construction worker fall within the boundary of a preset dangerous range, the remote monitoring platform will determine that the construction worker is in the dangerous area. When the target position of the construction worker is determined to be within the preset dangerous range, the remote monitoring platform will first try to determine the identity of the construction worker through the wireless communication module. This can usually be achieved through the identity recognition function in the wireless communication module, such as by reading the identity information in the identification plate worn by the construction worker, or by pairing and verifying with the personal device (such as mobile phone, bracelet, etc.) of the construction worker through the wireless communication module. Once the identity of the construction worker is confirmed, the remote monitoring platform will judge whether the construction worker has the permission to enter the dangerous range according to the preset permission database. The permission database can include information such as the name, position, working area, and dangerous area access permission of the construction worker. If the construction worker is authorized to enter the dangerous area, the remote monitoring platform may only record the entry situation and will not trigger further alarms. If an unauthorized construction worker enters the preset dangerous range, the remote monitoring platform will immediately trigger the danger warning mechanism, such as by sounding an alarm, sending an alarm message to the mobile phone or computer of the management personnel, etc., to notify the relevant personnel to take emergency measures immediately to ensure the safety of the construction worker.

[0074] By introducing the identity recognition and permission check mechanism, the remote monitoring platform can more precisely control and manage the safety risks at the construction site. Only authorized personnel can enter the dangerous area, thus reducing the probability of accidents. When an unauthorized person enters the dangerous area, the remote monitoring platform can immediately trigger the abnormal prompt mechanism, enabling the management personnel to quickly respond and take necessary measures to ensure the safety of the construction site. The information such as the activity track and time of the construction worker in the dangerous area recorded by the remote monitoring platform can provide important data support for subsequent safety analysis and accident investigation, helping to identify potential safety hazards and improve safety management measures.

[0075] S130. When the target position is not within the preset dangerous range, obtain the action track of the construction worker, count the total duration of the sub-action track, and judge whether the total duration is greater than the threshold, where the sub-action track is the action track outside the preset working range;

[0076] Set a preset working range according to the construction plan and site layout. At the same time, the remote monitoring platform sets a threshold value to determine whether the construction personnel deviate from the working area for a long time. This threshold value can be adjusted according to the actual situation, such as 30 minutes, 1 hour, etc. When the remote monitoring platform discovers through the interaction between the fixed beacon and the wireless communication module that the target position of the construction personnel is not within the preset working range nor within the preset danger range, it will record the action trajectory of the construction personnel. Especially those action trajectories that are not within the preset working range. Whenever the position of the construction personnel exceeds the preset working range, the remote monitoring platform will record the start time and end time of this sub-action trajectory and calculate its duration. As time goes by, the remote monitoring platform will accumulate multiple such sub-action trajectories and count their total duration. When this total duration exceeds the previously set threshold value within a cycle (such as a day), the remote monitoring platform will determine that the construction personnel have deviated from the working area for a long time. At this time, the remote monitoring platform can trigger the corresponding warning mechanism. For example, it can send an alarm message to the manager's mobile phone or computer to remind them to pay attention to the action trajectory of the construction personnel and possibly take necessary measures. The manager can make decisions according to the specific situation, such as communicating with the construction personnel to understand the situation, adjusting the work plan or arranging other personnel to assist, etc.

[0077] Optionally, the obtaining of the action trajectory of the construction personnel and the counting of the total duration of the sub-action trajectories include:

[0078] Obtain the target position of the construction personnel and the corresponding timestamp, and connect all the target positions to form an action trajectory;

[0079] Determine all the target positions that are not within the preset working range, and connect all the target positions that are not within the preset working range to form a sub-action trajectory;

[0080] Determine the sub-time period when leaving the preset working range in the sub-action trajectory according to the timestamp, and add up all the sub-time periods to obtain the total duration of the sub-action trajectory.

[0081] Each target location is attached with a corresponding timestamp, recording the exact time when the location was recorded. The remote monitoring platform will connect all the location points of the construction workers based on these target location data with timestamps to form a complete movement trajectory. This movement trajectory can reflect the movement path and distribution of the construction workers over a period of time. The remote monitoring platform determines the target locations that are not within the preset working range by comparing each target location with the boundaries of the preset working range. If the target location coordinates exceed the boundaries of the preset working range, then the remote monitoring platform will consider that location to be outside the working range. After determining all the target locations that are not within the preset working range, the remote monitoring platform will connect them to form one or more sub-movement trajectories. These sub-movement trajectories represent the movement of the construction workers in non-working areas. To calculate the total duration of these sub-movement trajectories, the remote monitoring platform needs to utilize the timestamps corresponding to each target location. The remote monitoring platform will determine the timestamp of the first location that leaves the preset working range in each sub-movement trajectory, and the timestamp of the last location that returns to the working range or ends the sub-movement trajectory. The difference between these two timestamps is the sub-time period during which the sub-movement trajectory leaves the working range. The remote monitoring platform will accumulate all the sub-time periods to obtain the total duration of all sub-movement trajectories. This total duration can reflect the situation of the construction workers deviating from the working area for a long time, helping the management to judge whether further measures need to be taken. For example, construction worker A leaves the preset working range for the first time at 10:00, returns to the preset working range for the first time at 10:05, leaves the preset working range for the second time at 11:30, and returns to the preset working range for the second time at 11:45. Therefore, the sub-time periods during which construction worker A leaves the preset working range are 10:00 - 10:05 and 11:30 - 11:45, and the total duration is 20 minutes.

[0082] By obtaining the target positions of construction workers and the corresponding timestamps in real time, the remote monitoring platform can accurately record the movement trajectories of construction workers. This includes not only their activities within the preset working range but also their situations of leaving the working area. This accurate recording method helps managers monitor and comprehensively understand the construction site in real time. By determining and connecting the target positions outside the preset working range, the remote monitoring platform can clearly identify the behaviors of construction workers deviating from the working area. This helps managers timely discover potential safety risks or work efficiency problems. Determine the sub-time periods when leaving the preset working range in the sub-movement trajectories according to the timestamps, and add up these sub-time periods to obtain the total duration. This step enables a quantitative analysis of the duration of construction workers deviating from the working area. This quantitative analysis can not only help managers understand the duration of the deviation behavior but also provide data support for subsequent decision-making and improvement measures. Through the analysis of the movement trajectories of construction workers and the total duration of the sub-movement trajectories, managers can more targeted take safety management measures. For example, for construction workers who frequently or for a long time deviate from the working area, training and supervision can be strengthened to reduce potential safety hazards. Through the statistical analysis of the movement trajectories of construction workers, managers can also understand their distribution in different working areas, so as to optimize resource allocation and scheduling. For example, the working area division can be adjusted or temporary work sites can be added according to the distribution of construction workers to improve work efficiency.

[0083] Optionally, the total duration of the statistical sub-movement trajectories includes:

[0084] Judge whether the first position in the sub-time period is within the preset rest range. When the first position is not within the preset rest range, determine the sub-time period as the first sub-time period. When the first position is within the preset rest range, determine the sub-time period as the second sub-time period. Add up all the first sub-time periods to obtain the total duration of the sub-movement trajectories.

[0085] Wherein, the first position and the second position are any two positions in the sub-movement trajectory, and the first distance between the first position and the geometric center of the preset working range is greater than the second distance between the second position and the geometric center of the preset working range.

[0086] The first position and the second position are any two positions in the sub-action trajectory. The first distance between the first position and the geometric center of the preset working range is greater than the second distance between the second position and the geometric center of the preset working range, indicating that the first position is the position farthest from the geometric center of the preset working range in the sub-action trajectory. Generally, the position farthest from the geometric center of the preset working range is the destination of the sub-action trajectory. If the first position is within the preset rest range, it is considered that the sub-action trajectory is in a normal rest state and does not belong to an abnormal state.

[0087] When counting the total duration of the sub-action trajectory, the remote monitoring platform will focus on the sub-action trajectories that are not within the preset working range. For each such sub-action trajectory, the remote monitoring platform will analyze each sub-time period therein. Within each sub-time period, the remote monitoring platform will determine whether the farthest position reached by the construction worker during this time period is within the preset rest range, which is usually achieved by comparing the target position of the construction worker with the boundary of the preset rest range. The preset rest range can include normal rest areas such as the cafeteria, toilet, and dormitory. If the first position is not within the preset rest range, it means that the construction worker has left the preset working range during working hours. At this time, the remote monitoring platform will mark this sub-time period as the first sub-time period, that is, the deviation time in the non-rest state. On the contrary, if the first position is within the preset rest range, then even if the construction worker has left the preset working range, they are considered to be in a legal rest state. At this time, the remote monitoring platform will mark this sub-time period as the second sub-time period, and this part of the time will not be included in the total duration of the sub-action trajectory. After all sub-time periods are classified as the first sub-time period or the second sub-time period, the remote monitoring platform will add up the time lengths of all the first sub-time periods, and the result obtained is the total duration of the sub-action trajectory. This total duration reflects the duration of the construction worker's long-term deviation from the working area in the non-rest state. In addition, the normal rest time can be set. For example, 12:00 - 14:00 is the normal rest time, and the action trajectory during this time period can be removed. However, it should be noted that if the construction worker goes to the cafeteria or dormitory during normal working hours, the time will also be included in the duration of deviating from the working area.

[0088] By determining whether the first position is within a preset rest range in a sub - time period, the remote monitoring platform can more accurately count the duration of construction workers in a non - working state. Only when the first position is not within the preset rest range will the corresponding sub - time period be included in the total duration of the sub - action trajectory. This helps to exclude the time when construction workers are in non - working states such as rest or short stays, making the statistical results more accurate. The setting of the preset rest range enables the remote monitoring platform to distinguish between the working state and non - working state of construction workers. When construction workers are within the preset rest range, even if they leave the preset working range, the remote monitoring platform will not regard it as a behavior of deviating from the working area for a long time. This distinction helps to avoid unnecessary interference and misjudgment of construction workers, improving the accuracy of management. By accurately counting the duration of construction workers in a non - working state, managers can arrange work plans and resource allocation more reasonably. For example, for construction workers who are in a non - working state for a long time, managers can understand the reasons and take corresponding measures, such as providing necessary support or adjusting work plans, to improve work efficiency and reduce resource waste. By accurately counting the total duration of the sub - action trajectory, managers can promptly discover and handle construction workers who deviate from the working area for a long time. This helps to reduce potential safety risks and improve the safety management level of the construction site.

[0089] Optionally, the counting of the total duration of the sub - action trajectory includes:

[0090] Determine the overlapping action trajectories among all construction workers' action trajectories, count the number of construction workers appearing in each overlapping action trajectory, and determine the time coefficient corresponding to each overlapping action trajectory according to the number, where the time coefficient is inversely proportional to the number;

[0091] Calculate the total duration of the sub - action trajectory according to the time coefficient.

[0092] Generally, there will be no overlapping of personnel in the action trajectories within the preset working range, unless a construction worker enters the preset working range corresponding to another construction worker. Since the overlapping path is short in this case, this situation is not considered in the embodiments of the present application. The embodiments of the present application mainly consider the action trajectories outside the preset working range. For example, for construction worker B, his sub - action trajectories outside the preset working range include a, b, c, d. a, b, c, d can be the same physical path at different times or different physical paths at different times. Suppose a corresponds to path 1 from 10:00 to 10:05. During the time period from 10:00 to 10:05, in addition to construction worker B, there are 9 other people who also passed through path 1. Then the time coefficient corresponding to path 1 in the time period from 10:00 to 10:05 is 1 / 10. It is necessary to calculate the total duration of construction worker B's sub - action trajectory according to the time coefficient.

[0093] By considering the situation of personnel overlap, the system can more accurately count the total duration of sub-action trajectories. When multiple people are in the same non-working area at the same time, simply adding up the duration of each person will lead to overcounting of the total duration. By determining the time coefficient based on the number of people and calculating the total duration accordingly, this overcounting situation can be avoided, thereby improving the accuracy of the statistics. The design where the time coefficient is inversely proportional to the number of people reflects that the impact on overall work efficiency and safety when multiple people act simultaneously is dispersed. This means that when multiple people deviate from the working area at the same time, the impact of each person on the whole is relatively small. This design is more in line with the actual situation and can more realistically reflect the impact of the behavior of construction site personnel on overall work efficiency and safety. By accurately counting the total duration of sub-action trajectories, managers can more precisely understand the distribution of construction personnel in non-working areas. This helps to optimize resource allocation, such as adjusting the division of working areas, adding temporary work stations, etc., to improve work efficiency and resource utilization rate. Accurately counting the total duration of sub-action trajectories helps managers to promptly discover and solve potential safety problems. For example, if there are frequent situations where multiple people deviate from the working area in a certain area, managers can strengthen safety monitoring and training for that area to reduce the occurrence of safety accidents.

[0094] Optionally, calculating the total duration of the sub-action trajectory according to the time coefficient includes:

[0095] Determine the overlapping action trajectories and non-overlapping action trajectories in the sub-action trajectory, perform weighted summation of the time coefficient corresponding to the overlapping action trajectories and the corresponding third sub-time period to obtain a fifth sub-time period, and add the fifth sub-time period to the fourth sub-time period to obtain the total duration of the sub-action trajectory. The third sub-time period refers to the time period corresponding to the overlapping action trajectory, and the fourth sub-time period refers to the time period corresponding to the non-overlapping action trajectory.

[0096] For example, for construction worker B, the sub-action trajectory outside the preset working range includes a, b, c, d. The time coefficients of a, b, c, d are 1 / 10, 1 / 2, 1, and 1 respectively, and the corresponding durations of a, b, c, d are 20 minutes, 10 minutes, 5 minutes, and 5 minutes respectively. Then the third sub-time period refers to the sub-time periods corresponding to a and b, the fourth sub-time period refers to the sub-time periods corresponding to c and d, the fifth sub-time period = 20 * 1 / 10 + 10 * 1 / 2 = 7 minutes, and the total duration = the fifth sub-time period + the fourth sub-time period = 7 + 5 + 5 = 17 minutes.

[0097] S140. When the total duration is greater than the threshold, determine that the action trajectory of the construction worker is abnormal and send a warning to the manager.

[0098] If the total duration of a construction worker's sub-action trajectory exceeds this threshold, the remote monitoring platform will determine that their action trajectory is abnormal. This means that the construction worker may have left the work area for a long time without a reasonable reason, and there may be problems such as work slack, illegal rest, or other issues. Once the remote monitoring platform determines that the action trajectory is abnormal, it will immediately send an alarm to the management personnel. The management personnel can further investigate the reasons based on the alarm information and take necessary measures, such as communicating with the construction worker, adjusting the work arrangement, or conducting safety education, etc.
