Description

Technical Field

[0001] The present invention relates to the field of carbon emission management, and particularly to a method for tracking the on-site process of inventory based on trajectories. Background Art

[0002] Carbon emission data is the basis for carbon market trading, and its authenticity and accuracy are crucial for the stable operation of the market. The authenticity of carbon emission data is directly related to the fairness and effectiveness of the carbon market. Therefore, ensuring the authenticity of data is the common responsibility of all participants. First of all, as the direct reporter of carbon emission data, enterprises need to be responsible for the authenticity, integrity, and accuracy of their emission data. Enterprises must establish an internal data quality management working mechanism, strengthen self-supervision, and ensure the standardization and accuracy of data. In addition, enterprises also need to cooperate with the government's regulatory requirements, report carbon emission data in a timely and accurate manner, and accept the verification of third-party verification agencies. If an enterprise falsifies its carbon emission report, it will not only face administrative penalties but may also be involved in civil and criminal liabilities. Secondly, third-party verification agencies also play an important role in ensuring data authenticity. They need to verify the carbon emission data of enterprises independently and impartially according to the specified standards and procedures and be responsible for their verification results. The data quality of verification agencies directly affects the credibility of the carbon market. In addition, the government undertakes the responsibilities of supervision and guidance in carbon emission data management. The government needs to establish a sound carbon emission data quality supervision system and ensure the authenticity and reliability of data through regular verification, supervision, and law enforcement activities. At present, enterprises, third-party verification agencies, and the government mainly rely on manual methods in aspects such as carbon emission data acquisition and review, and obtain and confirm data through on-site inspections combined with document reviews. On-site inspections are usually carried out by professional technical service agencies, consulting service agencies, or enterprise internal auditors to verify the accuracy of the data and information in the emission report. The inspection personnel will go to the site for on-site observation, inquiry, inspection, and verification to ensure the authenticity and reliability of the emission data. This includes inspections of emission facilities, audits of energy consumption and production processes, and verification of the data mentioned in the emission report. Document review is to conduct a detailed inspection of relevant documents to evaluate their compliance. This involves the review of the basic situation of the enterprise, accounting boundaries, accounting methods, and accounting data. The accuracy of data collection and processing is crucial for carbon emission management. To ensure data quality, it is required that the inspection personnel use the method of "inquiry, inspection, observation, and verification" to check and confirm the data and equipment information item by item.

[0003] However, carbon emission data has multiple dimensions and involves a wide range of departments and personnel. At present, the working hours, work effects, and other processes of on-site staff have not been effectively tracked, and it is impossible to determine whether the on-site work is compliant and regulate the behavior of on-site staff. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] The object of the present invention is to provide a method for tracking the process of on-site interrogation based on trajectories, so as to realize the control and transparent management of the on-site process.

[0044] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0045] Figure 1 For the schematic diagram of the process tracking of the on-site interrogation based on trajectories provided by the embodiments of the present invention, as Figure 1 shown, the present invention provides a method for tracking the process of on-site interrogation based on trajectories, including:

[0046] Step 100: Use a preset system to issue on-site work tasks to on-site interrogation personnel through the personal mobile devices of on-site interrogation personnel;

[0047] Step 200: Set the on-site work end time according to the on-site work task by on-site interrogation personnel, and start the trajectory recording program after the on-site work end time is set;

[0048] Step 300: Use the trajectory recording program to collect the location information and clock-in information of on-site interrogation personnel;

[0049] Step 400: Take the location information corresponding to the clock-in time of the first group of clock-in information as the starting point, and the task end location of the on-site work task as the end point, perform secondary position correction and trajectory fitting on the location information to obtain the running trajectory;

[0050] Step 500: Perform abnormal behavior detection on the running trajectory to obtain the abnormal behavior detection result, and display the abnormal behavior detection result on a preset WEB terminal;

[0051] Step 600: Perform node annotation and stay work time statistics on the running trajectory according to the clock-in information to obtain node information and statistical information, and display the node information and statistical information on the WEB terminal;

[0052] Step 700: Synchronously display the work content of the on-site work task, the abnormal behavior detection result, the node information, and the statistical information on the WEB terminal in the form of picture carousel.

[0053] Specifically, the position secondary rectification process includes:

[0054] Taking the position of the first punch-in point in the position information as the starting point, sequentially calculate the distance data between adjacent two punch-in point positions. If the distance data is less than the preset distance, record the punch-in point position corresponding to the distance data;

[0055] When the distance data is greater than the preset distance, determine the punch-in point position with a later sequence among the two punch-in point positions corresponding to the distance data as the offset point, and save the offset point to the memory storage;

[0056] Calculate the distance values between the offset point and the positions of the remaining punch-in points, update the punch-in point positions with distance values less than the preset distance to the first punch-in point position, and return to the step of "taking the position of the first punch-in point in the position information as the starting point, sequentially calculate the distance data between adjacent two punch-in point positions. If the distance data is less than the preset distance, record the punch-in point position corresponding to the distance data"; the remaining punch-in point positions are the punch-in point positions after the offset points arranged in sequence;

[0057] When there are four offset points in the memory storage, discard the offset point whose distance from the remaining offset points in the memory storage all exceeds the preset distance, and record the remaining offset points in the memory storage.

[0058] Preferably, the abnormal behavior detection results include: no running track during working hours, exceeding the factory boundary range, and the stay time at the punch-in point being less than the lower limit of the stay time threshold.

[0059] Specifically, the node information includes: project punch-in points, on-site photos of punch-in points, start punch-in time, GPS coordinates, and work end time.

[0060] Furthermore, it also includes:

[0061] Statistical non-optimal problems in the running tracks of the same on-site work task in different periods; the non-optimal problems include: path turning back and track overlapping;

[0062] Optimize the preset guiding path of the on-site work task according to the non-optimal problems to obtain the optimal on-site work route.

[0063] Preferably, the preset distance is 80 meters.

[0064] Optionally, it also includes:

[0065] Match the punch-in information to the running track in the way of track timestamps.

[0066] Optionally, it also includes:

[0067] Use a personal mobile device to upload the position information and punch-in information to a preset system through the information intranet.

[0068] Further, the position secondary rectification process further includes:

[0069] Select any recorded punch point position as the position to be rectified, and respectively determine the previous punch point position and the next punch point position of the position to be rectified as the upstream position and the downstream position;

[0070] Respectively calculate the distances between the position to be rectified and the upstream position and the downstream position to obtain the upstream distance and the downstream distance;

[0071] Update the position to be rectified where both the upstream distance and the downstream distance exceed the preset distance to the midpoint position of the connection line between the upstream position and the downstream position.

[0072] Even further, the position secondary rectification process further includes:

[0073] When any one of the upstream distance and the downstream distance is less than or equal to the preset distance, determine the position to be rectified as the normal position.

[0074] Specifically, the mobile terminal accesses the system clock-in and the WEB browser through the information intranet, and realizes project control through the interaction platform. The overall deployment architecture refers to Figure 2 .

[0075] Refer to Figure 3 (a) to Figure 3 (d). Use the personal mobile device of the on-site inspection personnel to log in to the system personal account, select a certain work task, and the system displays the on-site work tasks that need to be completed. The on-site personnel set the "on-site work end time" according to the expected end time and start the trajectory recording program. The inspection personnel go to the required location to punch the card and submit the position information, and carry out relevant work in this area according to the predetermined work tasks.

[0076] Refer to Figure 4, the WEB - end system displays in real - time information such as the running track, stay time, and work content of on - site inspection personnel: ① Map positioning and running track display: "Starting point" is displayed below the earliest manual clock - in point by clock - in time, and "End point" is displayed at the task - ending location. The system receives real - time personal mobile - end positioning information to display the running track for abnormal behavior detection (abnormal behaviors include: no running track during working hours, exceeding the factory boundary, too short stay time at the clock - in point, etc. The running track can be viewed and exported in real - time in the background for judging abnormal behaviors); ② Track details display: Use track timestamps to mark important nodes (important nodes mainly include project clock - in points. At the clock - in point, on - site personnel need to perform a series of operations such as taking on - site photos and uploading files. Important nodes will be marked on the track, recording the start clock - in time, GPS coordinates, and the time interval until work ends) and stay - at - work time statistics (obtain statistical information), optimize the on - site inspection work process (the on - site inspection work is carried out once a year and there are personnel replacements. Whether there are turn - backs, overlaps, etc. in the historical running track can be used to guide the confirmation of the optimal route for on - site work in subsequent years), and improve the on - site inspection efficiency; ③ Work content is displayed in a carousel of pictures, reflecting the on - site work situation and effectiveness.

[0077] Specifically, when the GPS signal at the location is weak, the system can use information such as track timestamps, longitude and latitude coordinates, speed, and direction, combined with the road conditions of the application scenario, to perform position correction. This embodiment provides a correction logic, including:

[0078] Before discarding correction at the clock - in point (the first screening):

[0079] The first clock - in point is stored by default. If the distance between the second clock - in point and the first clock - in point is less than 80 meters (the default setting is 80 meters), it is considered that this clock - in point is a normal point without deviation, and this point is recorded. The newly recorded point is determined as the first point (point A). The first point (point A) is compared with the next point (point B) and processed in turn. If it is less than 80 meters, it is recorded. If the distance between the second point (point B) and the first point (point A) is greater than 80 meters, it is considered that the second point (point B) is a deviated point and is stored in memory first. When the distance between the third point (point C) and the first point (point A) is less than 80 meters, the third point (point C) will be used as the first point for the next round of comparison. Comparison is carried out in this way until the number of points stored in memory is equal to four, and then pairwise comparison is performed. If the distance between one point and any other point exceeds 80 meters, this point is discarded. If the distance between one point and any other point is less than 80 meters, this point is recorded.

[0080] Secondary correction logic:

[0081] Compare pairwise within a limit of 80 meters. If the distance between the middle point and the previous point is no more than 80 meters and the distance between the middle point and the next point is no more than 80 meters, it is considered normal and no processing is required; if the distance between the middle point and the previous point exceeds 80 meters and the distance between the middle point and the next point is no more than 80 meters, it is considered normal and no processing is required; if the distance between the middle point and the previous point is no more than 80 meters and the distance between the middle point and the next point exceeds 80 meters, it is considered normal and no processing is required; if the distance between the middle point and the previous point exceeds 80 meters and the distance between the middle point and the next point exceeds 80 meters, it is considered that the middle point is offset, and the offset point is pulled back to the midpoint position of the line connecting the previous point and the next point.

[0082] The beneficial effects of the present invention are as follows:

[0083] Through positioning and trajectory tracking, the present invention records in real time the clock-in time, location, work intervals, and walking routes of on-site staff, collects the work of on-site staff at any time and in real time through the system and broadcasts it in a loop, realizes the effective tracking of the on-site areas that must be visited, the points that must be checked, the departments that must be reached, and the evidence that must be transmitted during the work process, makes the entire process of on-site inventory controllable, and improves the quality of carbon inventory data.

[0084] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same and similar parts among the embodiments, reference can be made to each other.

The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope.
