[0039] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be fully conveyed to those skilled in the art.

[0040] As Figure 1 shown, an embodiment of the present invention provides a method for determining the degree of change in a transmission line project, including:

[0041] Step 11, obtaining the first geographic information of the transmission line project and the second geographic information of the environmental impact assessment of the transmission line project;

[0042] Step 12, determining the change information between the first geographic information and the second geographic information according to the first geographic information and the second geographic information;

[0043] Step 13, determining the degree of change in the transmission line project according to the change information.

[0044] By comparing the first geographic information and the second geographic information, the present invention determines the degree of change in the transmission line project, realizes the accurate quantification and intelligent warning of the degree of change in the transmission line, and significantly improves the project compliance and economy.

[0045] Specifically, in step 11, the obtaining of the first geographical information of the transmission line project includes:

[0046] Obtaining the first path coordinates, the names of the first electromagnetic and noise sensitive points, the names of the first nature reserves, scenic spots, and ecological sensitive areas of drinking water source protection areas along the line during the construction drawing stage of the transmission line project.

[0047] In step 11, the obtaining of the second geographical information of the environmental impact assessment of the transmission line project includes:

[0048] Obtaining the second path coordinates, the names of the second electromagnetic and noise sensitive points, the names of the second nature reserves, scenic spots, and ecological sensitive areas of drinking water source protection areas along the line during the environmental impact assessment stage of the transmission line project.

[0049] In an optional embodiment of the present invention, in step 12, the determining of the change information between the first geographical information and the second geographical information according to the first geographical information and the second geographical information includes:

[0050] Step 121, determining the first change amplitude of the path length in the construction drawing stage compared with that in the environmental impact assessment stage according to the first path coordinates and the second path coordinates;

[0051] Step 122, determining the second change amplitude of the cumulative length of the lateral displacement of the line in the construction drawing stage exceeding the set value compared with that in the environmental impact assessment stage according to the first path coordinates and the second path coordinates;

[0052] Step 123, determining the third change amplitude of the newly added electromagnetic and acoustic environment sensitive targets in the construction drawing stage compared with that in the environmental impact assessment stage according to the names of the first electromagnetic and noise sensitive points and the names of the second electromagnetic and noise sensitive points;

[0053] Step 124, determining the fourth change situation of the ecological sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the line in the construction drawing stage compared with that in the environmental impact assessment stage according to the names of the first ecological sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the line and the names of the second ecological sensitive areas of nature reserves, scenic spots, and drinking water source protection areas along the line;

[0054] Step 125, determining the change information according to the relationships between the first change amplitude and the first set interval, the second change amplitude and the second set interval, the third change amplitude and the third set interval, and the fourth change situation and the fourth set situation.

[0055] In this embodiment, by quantifying the increase in path length (the first change range), the impact degree of the change in project scale on the environment can be intuitively reflected. The analysis of the cumulative length of lateral displacement (the second change range) can accurately identify the key sections where the construction line deviates from the environmental impact assessment design. The identification of newly added sensitive targets (the third change range) realizes the dynamic tracking of electromagnetic / noise sensitive points, and can timely discover the problems missed in the environmental impact assessment. The analysis of the changes in ecological sensitive areas (the fourth change situation) ensures the synchronous update of protection measures for special areas such as nature reserves, and avoids ecological damage. Through multi-dimensional data fusion analysis, the quantitative evaluation and intelligent determination of engineering design changes are realized.

[0056] In an alternative embodiment of the present invention, in step 125, the determining of the change information according to the relationships between the first change range and the first set interval, the second change range and the second set interval, the third change range and the third set interval, and the fourth change situation and the fourth set situation includes:

[0057] Step 1251, if any one of the conditions that the first change range exceeds the first set interval, the second change range exceeds the second set interval, the third change range exceeds the third set interval, and the fourth change situation conforms to the fourth set situation is satisfied, determine that the change information is a major change;

[0058] Step 1252, if any one of the conditions that the first change range conforms to the first set interval, the second change range conforms to the second set interval, and the third change range conforms to the third set interval is satisfied, determine that the change information is a major change warning;

[0059] Step 1253, if the three conditions that the first change range is less than the first set interval, the second change range is less than the second set interval, and the third change range is less than the third set interval are satisfied, determine that the change information is an allowable change.

[0060] Specifically, the first change range is the ratio of the increase in the path length in the construction drawing stage compared to the path length in the environmental impact assessment stage to the path length in the environmental impact assessment stage;

[0061] The second change range is the ratio of the cumulative length of the lateral displacement of the line in the construction drawing stage exceeding the set value compared to the path length in the environmental impact assessment stage to the path length in the environmental impact assessment stage;

[0062] The third change range is the ratio of the newly added electromagnetic and acoustic environment sensitive targets in the construction drawing stage compared to the environmental impact assessment stage to the number of electromagnetic and acoustic environment sensitive targets in the environmental impact assessment stage;

[0063] The fourth change situation is whether there are newly added ecological sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the line in the construction drawing stage compared to the environmental impact assessment stage.

[0064] The first set interval is 25%-30%, the second set interval is 25%-30%, the third set interval is 25%-30%, and the fourth set condition is that there are newly added ecological sensitive areas such as natural protection areas, scenic spots, and drinking water source protection areas along the line during the construction drawing stage compared with the environmental impact assessment stage.

[0065] In this embodiment, if any change index exceeds the limit (the path length exceeds 30%, the cumulative horizontal displacement exceeds 30%, the number of newly added sensitive points exceeds 30%, or a new ecological sensitive area is added), it is determined as a major change. This avoids the situation where a single index fails to meet the standard but other indicators seriously exceed the standard being missed. The addition of a new ecological sensitive area directly triggers a major change to ensure that the legal red line cannot be crossed. When any change index is between 25% and 30%, a warning is triggered. The design unit is allowed to fine-tune the path within a reasonable technical range to avoid unnecessary optimization costs caused by a "one-size-fits-all" approach. If all change indicators are less than 25% and there are no newly added sensitive areas, it is determined as an allowable change. This quickly releases low-risk projects and shortens the approval cycle.

[0066] Specifically, determining the proportion (the second change amplitude) of the cumulative length of the horizontal displacement of the line in the construction drawing stage compared with the environmental impact assessment stage that exceeds the set value includes:

[0067] According to Determine the horizontal displacement of the line in the construction drawing stage compared with the line in the environmental impact assessment stage,

[0068] where L i is the horizontal displacement between the line in the construction drawing stage and the line in the environmental impact assessment stage, (x i , y i ) are the coordinates of each point on the line in the construction drawing stage, (m i , n i ) are the coordinates of each point on the line in the environmental impact assessment stage, and i is the index value of each point, i = 1, 2, 3,..., n;

[0069] According to Determine the cumulative length of the horizontal displacement of the line in the construction drawing stage compared with the line in the environmental impact assessment stage that exceeds the set value,

[0070] where ∑L 超 is the cumulative length of the horizontal displacement of the line in the construction drawing stage compared with the line in the environmental impact assessment stage that exceeds the set value, L i is the horizontal displacement between the line in the construction drawing stage and the line in the environmental impact assessment stage, L 阈 is the set value (specifically, 500m can be taken), and i is the index value of each point, i = 1, 2, 3,..., n;

[0071] According to Determine the proportion (the second change range) of the cumulative length of the lateral displacement of the line in the construction drawing stage exceeding the set value to the path length in the environmental impact assessment stage,

[0072] where P is the proportion (the second change range) of the cumulative length of the lateral displacement of the line in the construction drawing stage exceeding the set value to the path length in the environmental impact assessment stage, and ∑L 超 is the cumulative length of the lateral displacement of the line in the construction drawing stage exceeding the set value compared to the line in the environmental impact assessment stage, and L 环总长 is the path length in the environmental impact assessment stage.

[0073] In this embodiment, the second change range provides a scientific and efficient environmental compliance assessment tool for the transmission line project by quantifying the cumulative impact of excessive lateral displacement. Its synergistic effect with other indicators.

[0074] In an optional embodiment of the present invention, in step 13, the determining the degree of change of the transmission line project according to the change information includes:

[0075] Step 131, determine that the degree of change of the transmission line project is a major change, a major change warning, or an allowable change according to the change information.

[0076] When the degree of change of the transmission line project is a major change, a warning shall be given to the construction drawing path plan. The construction unit shall feedback the result to the design unit, and the design unit shall optimize the line path in the construction drawing design stage and conduct a comprehensive study with the construction unit from aspects such as technology, environmental protection, economy, and restrictive factors to determine the final construction path plan.

[0077] When the degree of change of the transmission line project is a major change warning, a pre-warning shall be given to the construction drawing path plan. The construction unit shall feedback the result to the design unit, and the design unit shall optimize and adjust the line path in the construction drawing design stage to adjust the construction drawing path plan within the warning line to prevent a major change in the final construction path plan.

[0078] When the degree of change of the transmission line project is an allowable change, the path plan passes.

[0079] In this embodiment, it changes from passive rectification after completion to active optimization in the construction drawing stage, greatly reducing the project risk. Through quantitative indicators and elastic thresholds, it supports scientific decision-making and reduces human misjudgment. The automated process of pre-warning → optimization → release realizes an efficient closed-loop for change control.

[0080] The present invention comprehensively quantifies the degree of change through four-dimensional indicators, namely, the path length change rate, the cumulative proportion of excessive lateral displacement, the new proportion of sensitive targets, and the intrusion status of ecological sensitive areas. The post-completion inspection is advanced to the construction drawing stage to avoid problems being discovered only at the acceptance stage. A warning range of 25%-30% is set to allow fine-tuning of the path within a reasonable technical range, reducing the need for unnecessary environmental impact assessment changes. The addition of an ecological sensitive area directly triggers a major change warning to ensure that the legal red line cannot be crossed. Shifting from passive rectification to active optimization significantly reduces project risks. The combination of quantitative indicators and flexible thresholds supports scientific decision-making and reduces human misjudgment. The automated process of warning → optimization → release realizes an efficient closed-loop for change control.

[0081] As Figure 2 shown, a specific implementation process of the present invention is as follows:

[0082] First, the construction unit collects the first path coordinates, the names of the first electromagnetic and noise sensitive points, and the names of ecological sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the first line (the first geographical information) in the construction drawing stage of this transmission line, and imports them into the map software, naming it the construction drawing path of the XXX project.

[0083] Second, the construction unit collects the second path coordinates, the names of the second electromagnetic and noise sensitive points, and the names of ecological sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas along the second line (the second geographical information) in the environmental impact assessment stage of the transmission line, and imports them into the map software, naming it the environmental impact assessment path of the XXX project.

[0084] Start the major change judgment program for the transmission line. After that, the software will judge whether there is a major change in the construction drawing transmission line path plan according to the pre-set major change judgment conditions for the transmission line.

[0085] 1. If there is no major change in the transmission line path or the path change does not reach the warning threshold, the path plan passes, and the system prompts that the path plan is feasible.

[0086] 2. If the path change of the transmission line has reached the warning standard for major changes, that is, when comparing the plan in the construction drawing stage with the plan in the environmental impact assessment stage, the changes in the construction drawing stage compared with the environmental impact assessment stage meet the following conditions:

[0087] (1) The path length in the construction drawing stage increases by more than 25%-30% of the path length of the environmental impact assessment path plan.

[0088] (2) The cumulative length of the lateral displacement of the construction drawing line exceeding 500 meters exceeds 25%-30% of the path length of the environmental impact assessment path plan.

[0089] 3. Due to changes in the route of the construction drawing, the number of newly added electromagnetic and acoustic environment sensitive targets exceeds 25% - 30% of the number of the environmental impact assessment (EIA) route plan.

[0090] Then a warning is issued for the construction drawing route plan, indicating that a major change in the construction drawing route plan is about to occur. The construction unit should feedback the result to the design unit, and the design unit should optimize and adjust the route of the construction drawing design stage to bring the construction drawing route plan within the warning line to prevent major changes in the final construction route plan.

[0091] If the change in the transmission line route already meets the conditions for major changes, that is, compared with the EIA plan in the construction drawing stage, the following conditions are met for the changes in the construction drawing stage compared with the EIA plan:

[0092] 1. The increase in the route length in the construction drawing stage exceeds 30% of the route length of the EIA route plan.

[0093] 2. The cumulative length of the lateral displacement of the construction drawing line exceeding 500 meters exceeds 30% of the route length of the EIA route plan.

[0094] 3. Due to changes in the route of the construction drawing line, the number of newly added electromagnetic and acoustic environment sensitive targets exceeds 30% of the number of the EIA route plan.

[0095] 4. Due to changes in the route plan of the construction drawing line, it leads to entering new ecological sensitive areas such as nature reserves, scenic spots, and drinking water source protection areas.

[0096] Then a warning is issued for the construction drawing route plan, indicating that a major change has occurred in the construction drawing line route plan. The construction unit should feedback the result to the design unit, and the design unit should optimize the route of the construction drawing design stage and conduct a comprehensive review with the construction unit from aspects such as technology, environmental protection, economy, and restrictive factors to determine the final construction route plan. If, after route optimization, the route plan no longer belongs to a major change, then the construction unit should carry out construction work based on the optimized construction drawing. If, after the route plan is adjusted, it still belongs to a major change, but it is considered more reasonable after a comprehensive review from multiple aspects such as technology, environmental protection, economy, and restrictive factors. Then the construction unit starts the preparation work for the changed EIA in synchronization with the optimized route plan of the construction drawing to prevent the acceptance work.

[0097] The present invention realizes the automatic judgment of major changes in transmission lines, replaces manual measurement and judgment, etc., realizes high-precision and automatic judgment, and reduces the possibility of misjudgment caused by human operation. It saves project investment and shortens the project completion time. The present invention realizes the early intervention of major change judgment, prevents and reduces the occurrence of major changes in transmission line projects, and achieves the purpose of optimizing the line path by the construction unit, saving project investment and shortening the project acceptance period. The present invention realizes that if there are major changes in the line path, the change environmental impact assessment work can be carried out synchronously according to the final construction path at the construction drawing stage, without affecting the subsequent project completion environmental protection acceptance and the work of the second-phase project.
