[0024] To solve the problems proposed in the background, the application adopts the combination of GPS positioning technology and information management system, and displays the real-time positioning data of construction equipment and personnel on the infrastructure map, and compares it with the preset guidance scheme, to realize the precise evaluation of the construction state.

[0025] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings of the specification and the specific embodiments.

[0026] Embodiment one:

[0027] As shown in FIG. 1, the embodiment provides a positioning supervision method based on a power grid infrastructure project, which includes the following steps: Figures 1-2

[0028] ​S100. Obtain a capital construction map and positioning data fed back by GPS receivers in real time; wherein the GPS receivers are configured on construction equipment and personnel, and each GPS receiver is configured with a unique target identifier.

[0029] In S100, the capital construction map can be a remote sensing map containing longitude and latitude, so as to provide a basis for subsequent positioning display and motion information analysis. The GPS receivers are configured on the construction equipment and personnel, and each receiver is ensured to have a unique target identifier, so as to not only distinguish different equipment and personnel, but also ensure the accuracy and traceability of the positioning data. When the construction equipment and personnel move, the GPS receivers will capture their longitude and latitude coordinates in real time and feed these data back to the system, providing key data support for subsequent construction state assessment and progress, and determination of abnormal information.

[0030] S200. Display the positioning data of the target identifier on the capital construction map.

[0031] In S200, the positioning data of each target identifier (i.e. construction equipment and personnel) obtained from the GPS receivers is displayed on the capital construction map in real time, so that the real-time situation of the construction site can be intuitively seen, including the specific location and moving track of the equipment and personnel. By combining the positioning data with the capital construction map, not only can the management personnel better understand the layout and resource allocation of the construction site, but also can provide intuitive visual support for subsequent motion information analysis and construction state assessment, which helps to discover and solve potential problems in construction in a timely manner, and improves the efficiency and accuracy of construction management.

[0032] S300. Obtain motion information of the target identifier on the capital construction map.

[0033] In S300, on the basis of the real-time feedback of the positioning data by the GPS receivers, these data are further analyzed to extract the moving track and other parameters of the target identifier on the map. These motion information not only reflects the dynamic situation of the construction site, but also reveals the activity rules and efficiency of the construction equipment and personnel. Through in-depth analysis of the motion information, the overall state of the construction site can be more accurately grasped, and more detailed data support can be provided for subsequent construction state assessment and progress, and determination of abnormal information.

[0034] S400. Compare the motion information with a preset guidance scheme to assess the construction state.

[0035] In S400, by analyzing the key information such as the movement trajectory, stay time, etc. of each target identification (i.e. construction equipment and construction personnel) on the infrastructure map, and comparing these information with the detailed guidance scheme formulated at the initial stage of the project one by one, the larger deviation or behavior not meeting the expectation in the construction process can be accurately identified, such as the equipment moving not according to the planned route, the construction personnel staying at the wrong position or for too long time, etc. This real-time evaluation mechanism provides strong decision support for project managers, enabling them to quickly identify and respond to potential problems, ensure that construction activities are strictly in accordance with the established scheme, and effectively maintain the construction progress and timely discover abnormal information.

[0036] S500. Determine the construction progress and abnormal information according to the construction state.

[0037] In S500, according to the comparison result of the movement information and the guidance scheme, the construction state is comprehensively evaluated. If the movement information of the construction equipment and personnel is highly consistent with the preset scheme, it can be judged that the construction progress is normal; otherwise, if there is a significant deviation, it is determined to be abnormal, so that a reminder can be issued for the staff to take appropriate measures. Therefore, project managers can quickly grasp the construction progress and respond and handle potential construction problems in a timely manner, thereby ensuring the smooth progress and efficient management of the power grid infrastructure project.

[0038] In S400, the guidance scheme includes the construction site and the moving route displayed on the infrastructure map; wherein the construction site and the moving route are both regions with boundary lines.

[0039] The guidance scheme not only plans the construction site in detail, but also clearly sets the moving route of the construction equipment and personnel, and these construction sites and moving routes have clear boundary line regions, ensuring the accuracy and safety of the construction activities. By comparing the real-time movement information with these regions with boundary lines, the system can more accurately evaluate whether the construction is proceeding as planned.

[0040] In S200, the positioning data includes coordinates and time stamps corresponding to the coordinates; in S400, the movement information of the target identification is specifically: generating the movement trajectory of the target identification according to the continuous positioning data, and the time period corresponding to the movement trajectory.

[0041] The positioning data has a time dimension, and the movement trajectory of the construction equipment and personnel not only depicts the moving path of the equipment and personnel in the construction site, but also carries the corresponding time period information, i.e. the duration of the movement trajectory, which can more comprehensively grasp the dynamic situation of the construction site.

[0042] In S400, comparing the movement information with the preset guidance scheme to evaluate the construction state is specifically:

[0043] S410. Initialize all construction sites as non-construction state.

[0044] S420. Continuously traverse all construction sites in non-construction state, for the current traversed construction site:

[0045] S421. Obtain positioning data from GPS receivers within the area of the construction site in a specified time period.

[0046] S422. Determine whether the positioning data contains feedback from all GPS receivers; if yes, change the non-construction state of the construction site to completed construction state; if no, determine whether the number of positioning data is 0; if the number of positioning data is not 0, change the non-construction state or completed construction state of the construction site to construction in progress state.

[0047] In S410-S422, all construction sites are preset as non-construction state, and a continuous traversal mechanism is adopted to check these construction sites one by one. For the current traversed construction site, the positioning data provided by all GPS receivers within the area of the construction site in a specified time period is collected. If the collected positioning data completely contains the feedback from all participating GPS receivers, it indicates that the construction site has all construction equipment and construction personnel, which may be a construction site in progress or a construction site that has completed construction. First, update the state of the construction site to completed construction. If the data is incomplete but not empty, it means that there is construction activity but the expected participation has not been reached, indicating that construction equipment and construction personnel are entering or leaving the construction site, but have not completely entered or completely left, so the construction site is in construction in progress state. If the data is completely missing, it means that the construction site is still in non-construction state.

[0048] In S500, determining the construction progress includes: determining whether there is a construction site in construction in progress state in real time; if yes, the construction progress Cs is: If no, calculate the construction progress Cs, and the construction progress Cs is: Wherein, Acc represents the construction site in completed construction state, and Ccc represents all construction sites.

[0049] If the system determines that there is a construction site in construction in progress state, the formula for calculating the construction progress will be adjusted to Here, 0.5 is added to reflect the contribution of those construction sites in progress but not yet completed to the construction progress to some extent, although they have not yet reached the completely completed state. Conversely, if the system determines that there is no construction site in construction in progress state, i.e., all construction sites are either completed or have not started, the formula for calculating the construction progress is simplified to In this case, the construction progress is directly determined by the proportion of completed construction sites. This method of dynamically adjusting the calculation formula according to the construction status can accurately reflect the current construction progress in real time, making the evaluation of construction progress more in line with the actual situation and helping project managers make more informed decisions.

[0050] Embodiment Two:

[0051] On the basis of Embodiment One, in S500, the guidance scheme further includes a completion deadline corresponding to each construction site; and the determination of abnormal information includes at least one of Method A or Method B:

[0052] Method A: S510. Determine the starting time point when the construction site changes from the non-construction state to the construction state, and the ending time point when the construction state changes to the completed construction state; S520. Calculate the construction time according to the starting time point and the ending time point; S530. Determine whether the construction time is not greater than the completion deadline, if not, determine that the construction site is abnormal construction.

[0053] Method B: S511. In a specified time period, determine in real time whether the target identifier is located within the area of the construction site and the moving route, if not, record the time value when the target identifier leaves the area; S521. Determine in real time whether the time value is greater than a preset value, if yes, determine that the target identifier is abnormal.

[0054] Method A is a means of monitoring construction progress. First, determine the starting time when the construction site changes from non-construction to construction, and the ending time when the construction changes from construction to completion. These two time points are used to calculate the actual construction duration. Then, compare the calculated construction duration with the preset completion deadline. If the construction duration does not exceed the deadline, it is considered normal; otherwise, if it exceeds, mark the construction site as abnormal, indicating that there may be progress delays or problems. Through this method, the construction status can be monitored in real time, and progress abnormalities can be addressed in a timely manner to ensure that the project is completed according to the plan.

[0055] Method B is a method for monitoring the status of a specific target (such as a construction worker, equipment, etc.) within a construction area and movement route, aiming to ensure that the target behaves as expected within the construction area. By continuously collecting location information of the target identifier and comparing it with the geographical boundaries of the construction area and movement route, real-time monitoring of the target's activity range is achieved, and real-time judgment is made within a specified time period as to whether the target identifier is located within the construction site and its preset movement route. If the system finds that the target identifier has left the construction area or movement route at a certain time, it will immediately record the time value of this departure from the area, and through real-time judgment, it will determine whether the recorded time value exceeds the preset threshold (such as the maximum time allowed for the target to temporarily leave). If the time value exceeds the preset value, the system will determine that the target identifier is in an abnormal state, which usually means that the target may not be performing construction activities as planned, and further investigation and handling are required.

[0056] Embodiment Three:

[0057] As shown in Embodiment One, the abnormal information includes: Figure 3

[0058] Sa510. Determine the construction type of the construction site in the construction state according to the preset construction planning information.

[0059] Sa520. Determine the combination device according to the construction type, and the movement planning information of the combination device; wherein the combination device includes at least two construction devices, and the movement planning information includes the preset movement trajectory of the at least two construction devices and the time period corresponding to the movement trajectory.

[0060] Sa530. Obtain the movement information of the combination device.

[0061] Sa540. Compare the movement information of the combination device with the movement planning information to determine whether the combination device is abnormal.

[0062] For construction sites with similar construction plans, they can be classified into the same construction type. In the same construction type of construction site, some common construction equipment has similar movement trajectory under certain conditions, such as the line laying frame, tension machine and traction machine. In the process of power line construction, the line laying frame is used to support and fix the wire or cable, while the tension machine and traction machine are used to control the tension and traction direction of the wire or cable. When the wire or cable needs to be laid on a specific path, the line laying frame, tension machine and traction machine usually work together to form a relatively fixed movement trajectory. In this case, if the construction site and the laying path are the same, the movement trajectory of these devices may remain consistent. Just like the drilling machine and the pile driver, the power generation control unit, the power transmission allocation system and the power distribution monitoring device, these combinations of devices all include two or more interrelated devices. ​

[0063] Since the combined device has similar motion trajectories in different construction site cases of the same construction type, based on this characteristic, the known motion trajectory can be used to determine whether the motion state of the combined device in the subsequent construction process is abnormal.

[0064] The motion planning information includes trigger trajectories and planning trajectories, and the trigger time period corresponding to the trigger trajectories and the time period corresponding to the monitoring trajectories, respectively. The motion information of the combined device includes trigger subsequences and to-be-monitored sequences, and the time period corresponding to the trigger subsequences and the to-be-monitored sequences, respectively. Comparing the motion information of the combined device with the motion planning information to determine whether the combined device is abnormal includes:

[0065] Sa541. Generate all subsequences of the motion information of the combined device.

[0066] Sa542. Calculate the similarity between the trigger trajectory and each subsequence.

[0067] Sa543. Determine the trigger subsequence among all subsequences according to the similarity, and determine the to-be-monitored sequence according to the trigger subsequence.

[0068] Sa544. Calculate the similarity between the to-be-monitored sequence and the planning trajectory.

[0069] Sa545. Determine whether the similarity between the to-be-monitored sequence and the planning trajectory is less than a preset threshold, and if so, determine that the combined device is abnormal.

[0070] In Sa541-Sa545, the trigger trajectory is a predefined trajectory that triggers subsequent monitoring actions when a part of the motion trajectory of the combined facility is similar to it. Once the trigger trajectory is identified, the system will start the motion trajectory and time of the combined facility after the trigger trajectory.

[0071] Generating all possible subsequences of the motion information of the combined device, by calculating the similarity between the trigger trajectory and each subsequence, the trigger subsequence that best matches the trigger trajectory can be determined among all subsequences. Once the trigger subsequence is determined, we can accordingly find the to-be-monitored sequence, which is the motion trajectory in the specified time period after the trigger subsequence.

[0072] Calculate the similarity between the to-be-monitored sequence and the planning trajectory to evaluate whether the actual motion of the combined device is consistent with the preset planning. If the similarity between the to-be-monitored sequence and the planning trajectory is lower than the preset threshold, the system determines that the combined device motion is abnormal, which may be caused by device failure, operation error or other external factors.

[0073] If the time length of the triggered trajectory is t, when generating all possible subsequences of the combined device motion information, starting from the starting point of the triggered trajectory, each data point is traversed in time sequence, and a subsequence is generated by searching backward from the current data point for a time period of t. If the remaining data points are insufficient to form a complete t time period or the number of data points, the generation of a new subsequence is stopped, and all subsequences are obtained. Using a similarity measurement method, the similarity between trajectory B and each subsequence in trajectory A can be calculated.
