[0002] Grid infrastructure refers to new construction and expansion of asset projects implemented to provide power transmission and distribution services, including power transmission and transformation projects of various voltage levels and independent secondary projects.

[0003] Grid infrastructure is the main way to expand the scale of the grid and improve the grid structure. It is of great significance to ensure power supply and promote economic and social development. The real-time tracking of the construction progress of grid infrastructure projects and the capture of abnormal information often rely on manual reports or regular inspections. Due to the subjectivity and delay of manual reports, it is difficult to timely and accurately reflect the real-time location of construction equipment and construction personnel, resulting in the difficulty of accurately grasping the construction progress. At the same time, although regular inspections can find some obvious problems, it is often difficult to timely discover and deal with abnormal situations that are highly concealed or sudden.

[0024] In order to solve the problems raised in the background, this application adopts a combination of GPS positioning technology and information management system. By displaying the real-time positioning data of construction equipment and personnel on the infrastructure map and comparing it with the preset guidance plan, an accurate assessment of the construction status is achieved.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Embodiment 1:

[0027] like Figure 1-Figure 2 As shown, this embodiment provides a method for positioning and supervising a power grid infrastructure project, which includes the following steps:

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

[0029] In S100, infrastructure maps can be remote sensing maps containing longitude and latitude to provide a basis for subsequent positioning display and motion information analysis. GPS receivers are configured for construction equipment and construction personnel, and each receiver is ensured to have a unique target identifier, which can not only distinguish different equipment and personnel, but also ensure the accuracy and traceability of positioning data. When construction equipment and construction personnel move, the GPS receiver 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 status assessment and progress, and determination of abnormal information.

[0030] S200. Display the positioning data of the target identification on the infrastructure map.

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

[0032] S300. Obtain movement information of the target marker on the infrastructure map.

[0033] In S300, based on the real-time feedback of positioning data from the GPS receiver, these data are further analyzed to extract parameters such as the movement trajectory of the target mark on the map. These movement information not only reflects the dynamic situation of the construction site, but also reveals the activity patterns and efficiency of construction equipment and personnel. Through in-depth analysis of movement information, the overall status of the construction site can be more accurately grasped, providing more detailed data support for subsequent construction status evaluation and progress and abnormal information determination.

[0034] S400. Compare the motion information with a preset guidance plan to evaluate the construction status.

[0035] In S400, by analyzing the movement trajectory, stay time and other key information of each target identifier (i.e. construction equipment and construction personnel) on the infrastructure map, and comparing this information with the detailed guidance plan formulated at the beginning of the project, it can accurately identify large deviations or behaviors that do not meet expectations during the construction process, such as equipment not moving according to the planned route, construction personnel staying in the wrong location or for too long, etc. This real-time evaluation mechanism provides powerful decision-making support for project managers, enabling them to quickly identify and respond to potential problems, ensure that construction activities are carried out strictly in accordance with the established plan, and effectively maintain the construction progress and detect abnormal information in a timely manner.

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

[0037] In S500, the construction status is comprehensively evaluated based on the comparison results of the motion information and the guidance plan. If the motion information of the construction equipment and personnel is highly consistent with the preset plan, then the construction progress can be judged to be normal; on the contrary, if there is a significant deviation, it is determined to be abnormal, so that a reminder can be issued so that the staff can take corresponding 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 power grid infrastructure projects.

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

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

[0040] In S200, the positioning data includes coordinates and timestamps corresponding to the coordinates; in S400, obtaining the motion information of the target identifier specifically includes: generating a motion trajectory of the target identifier and a time period corresponding to the motion trajectory according to the continuous positioning data.

[0041] Positioning data has a time dimension. The movement trajectory of construction equipment and construction personnel not only depicts the movement paths of equipment and personnel at the construction site, but also comes with corresponding time period information, that is, the duration of the movement trajectory, which can more comprehensively grasp the dynamic situation of the construction site.

[0042] In S400, the motion information is compared with a preset guidance scheme to evaluate the construction status:

[0043] S410. Initialize all construction sites to an unconstructed state.

[0044] S420. Continuously traverse all construction sites that are not under construction, and for the currently traversed construction site:

[0045] S421. Obtain positioning data fed back by a GPS receiver within the area of ​​the construction site within a specified time period.

[0046] S422. Determine whether the positioning data contains feedback from all GPS receivers; if so, change the unconstructed state of the construction site to the completed state; if not, determine whether the amount of positioning data is 0. If the amount of positioning data is not 0, change the unconstructed state or the completed state of the construction site to the under-construction state.

[0047] In S410-S422, all construction sites are preset to be in an unconstructed state, and a continuous traversal mechanism is used to check these construction sites one by one. For the currently traversed construction site, the positioning data provided by all GPS receivers in the area of ​​the site within a specific time period are collected. If the collected positioning data completely includes the feedback from all GPS receivers that should be involved, it indicates that the construction site once or currently has all the construction equipment and construction personnel. It may be a construction site under construction or a construction site that has completed construction. The construction site status is first updated to completed construction. If the data is incomplete but not empty, it means that there is construction activity but the expected participation rate has not been reached. This means that the construction equipment and construction personnel are entering or leaving the construction site but have not completely entered or left. Therefore, the construction site is in a state of under construction. If the data is completely missing, it means that the construction site is still in a state of not under construction.

[0048] In S500, determining the construction progress includes: determining in real time whether there is a construction site under construction; if so, the construction progress Cs is: If not, calculate the construction progress Cs, which is: Among them, Acc represents the construction site in the completed construction status, and Ccc represents all construction sites.

[0049] If the system determines that there is a construction site under construction, the calculation formula for the construction progress will be adjusted to The reason for adding 0.5 here is to reflect the contribution of those construction sites that are in progress but not yet completed to the construction progress to a certain extent, although they have not yet reached a fully completed state. On the contrary, if the system determines that there are no construction sites in progress, that is, all construction sites are either completed or have not yet started, then the calculation formula for the construction progress is simplified to In this case, the construction progress is directly determined by the proportion of completed construction sites. It can reflect the current construction progress in real time and accurately. This practice of dynamically adjusting the calculation formula according to the construction status also makes the evaluation of the construction progress more in line with the actual situation, which helps project managers make more informed decisions.

[0050] Embodiment 2:

[0051] Based on the first embodiment, in S500, the guidance scheme further includes a completion deadline corresponding to each construction site; determining the abnormal information includes at least one of method A or method B:

[0052] Method A: S510. Determine the start time point when the construction site changes from the non-construction state to the construction state, and the end time point when the construction state changes from the completion state; S520. Calculate the construction time based on the start time point and the end 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 the specified time period, determine in real time whether the target identification is located within the area of ​​the construction site and the moving route. If not, record the time value when the target identification leaves the area; S521. Determine in real time whether the time value is greater than the preset value. If so, determine that the target identification is abnormal.

[0054] Method A is a means of monitoring construction progress. First, determine the start time when the construction site changes from unconstructed to under construction, and the end time when it changes from under construction to completed. These two time points are used to calculate the actual construction duration. Next, the calculated construction duration is compared with the preset completion deadline. If the construction duration does not exceed the deadline, it is considered normal; conversely, if it exceeds the deadline, the construction site is marked as abnormal, indicating that there may be delays or problems in the progress. Through this method, the construction status can be grasped in real time, and progress abnormalities can be responded to in a timely manner to ensure that the project is completed as planned.

[0055] Method B is a method for monitoring the status of specific targets (such as construction personnel, equipment, etc.) in the construction area and movement route, aiming to ensure that the target moves in the construction area as expected. By continuously collecting the location information of the target identification and comparing it with the geographical boundaries of the construction area and movement route, the real-time monitoring of the target's activity range is achieved, and it is judged in real time whether the target identification is located in the area of ​​the construction site and its preset movement route within the specified time period. If the system finds that the target identification has left the construction area or movement route at a certain moment, it will immediately record the time value of this departure from the area, and judge in real time whether the recorded time value exceeds the preset threshold (such as the maximum time allowed for the target to leave for a short time). If the time value exceeds the preset value, the system will determine that the target identification is in an abnormal state, which usually means that the target may not carry out construction activities as planned and requires further investigation and processing.

[0056] Embodiment three:

[0057] like Figure 3 As shown, based on the first embodiment, determining the abnormal information includes:

[0058] Sa510. Determine the construction type of the construction site under construction based on the preset construction planning information.

[0059] Sa520. Determine the combination equipment and the motion planning information of the combination equipment according to the construction type; wherein the combination equipment includes at least two construction equipment, and the motion planning information includes preset motion trajectories of the at least two construction equipment and the time period corresponding to the motion trajectories.

[0060] Sa530. Get the motion information of the combined device.

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

[0062] For construction sites with similar construction plans, they can be classified as the same construction type. In construction sites of the same construction type, some common construction equipment have similar motion trajectories under specific conditions, such as: pay-off racks, tensioners and traction machines. During the construction of power lines, pay-off racks are used to support and fix wires or cables, while tensioners and traction machines are used to control the tension and traction direction of wires or cables. When wires or cables need to be laid on a specific path, pay-off racks, tensioners and traction machines usually work together to form a relatively fixed motion trajectory. In this case, if the construction site and laying path are the same, the motion trajectories of these devices may remain consistent. Another example is a drilling machine and a pile driver, a power generation control unit-a power transmission and dispatching system-a power distribution monitoring device. These equipment combinations all contain two or more interrelated devices.

[0063] Since the combined equipment has similar motion trajectories at different construction sites 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 equipment in the subsequent construction process is abnormal.

[0064] The motion planning information includes the trigger trajectory and the planning trajectory, as well as the trigger time period corresponding to the trigger trajectory and the time period corresponding to the monitoring trajectory respectively; the motion information of the combined device includes the trigger subsequence and the sequence to be monitored, as well as the time periods corresponding to the trigger subsequence and the sequence to be monitored 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 motion information of the combined device.

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

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

[0068] Sa544. Calculate the similarity between the monitored sequence and the planned trajectory.

[0069] Sa545. Determine whether the similarity between the sequence to be monitored and the planned 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. When a part of the motion trajectory of the combined facility is similar to it, it will trigger the subsequent monitoring action. Once the trigger trajectory is identified, the system will start the motion trajectory and time of the combined facility after the trigger trajectory.

[0071] Generate all possible subsequences of the combined device motion information. 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 find the sequence to be monitored accordingly. The motion trajectory within the specified time period after the trigger subsequence is the sequence to be monitored.

[0072] The similarity between the sequence to be monitored and the planned trajectory is calculated to evaluate whether the actual movement of the combined equipment is consistent with the preset plan. If the similarity between the sequence to be monitored and the planned trajectory is lower than the preset threshold, the system determines that the movement of the combined equipment is abnormal, which may be caused by equipment failure, operational error or other external factors.

[0073] If the duration of the trigger trajectory is t, when generating all possible subsequences of the combined device motion information, start from the starting point of the trigger trajectory, traverse each data point in chronological order, take the current data point as the starting point, and search backward for a time period of length t to generate a subsequence. If the remaining data points are not enough to form a complete t time period or number of data points, stop generating new subsequences, and you can get all subsequences. Using the similarity measurement method, you can calculate the similarity between each subsequence in trajectory B and trajectory A.

[0074] Embodiment 4:

[0075] like Figure 4 As shown, this embodiment provides a positioning supervision system based on power grid infrastructure projects, which adopts the positioning supervision method based on power grid infrastructure projects as in Example 1, and includes: a data acquisition module, a data fusion module, a motion information acquisition module, an evaluation module and an information determination module.

[0076] The data acquisition module is used to obtain the infrastructure map and the positioning data fed back by the GPS receiver in real time; wherein, the GPS receiver is configured on the construction equipment and construction personnel, and each GPS receiver is configured with a unique target identifier; the data fusion module is used to display the positioning data of the target identifier on the infrastructure map; the motion information acquisition module is used to obtain the motion information of the target identifier on the infrastructure map; the evaluation module is used to compare the motion information with the preset guidance plan to evaluate the construction status; the information determination module is used to determine the construction progress and abnormal information according to the construction status.
