Description

Technical Field

[0001] The present invention relates to the technical field of regional network coverage monitoring and optimization, and in particular to a whole-process simulation method for a power grid infrastructure project. Background Art

[0002] In power grid infrastructure, wireless networks have become an indispensable infrastructure in modern office and residential environments. However, the unevenness of wireless signal coverage and the uncertainty of network performance often lead to inconsistent user experience. Traditional wireless network deployment methods often lack accurate evaluation of actual coverage, making it difficult to carry out targeted network optimization work, affecting the overall performance of the network and user satisfaction.

[0003] Existing wireless network monitoring and management methods usually rely on manual testing and empirical judgment, which are not only inefficient but also difficult to achieve a comprehensive and objective evaluation of network coverage. In addition, existing methods also have shortcomings in processing large-scale network data, achieving network performance prediction, and optimizing network resource allocation.

[0004] In the field of wireless network coverage monitoring and management, how to achieve real-time monitoring, accurate evaluation and intelligent optimization of network coverage to improve network performance and user satisfaction is a technical problem that needs to be solved urgently. Existing technologies often ignore the complexity of the network environment and the diversity of user behavior, and lack personalized services and refined management.

[0005] Therefore, developing a simulation method for the entire process of power grid infrastructure projects to achieve real-time monitoring, dynamic analysis and intelligent management of wireless network coverage during infrastructure construction has become an important research direction in the field of wireless network management. This new method needs to be able to accurately monitor wireless signal coverage, deeply analyze network performance, accurately predict network demand trends, and provide personalized network optimization recommendations and services to network operators and users to improve the intelligence level of wireless network management and user network experience.

[0034] Mark the point where the vertical line E intersects the vertical line R as the best monitoring point.

[0036] According to the classification level of each room in the second type of monitoring area set B, the area is divided and the geometric center of the corresponding area is obtained, specifically:

[0037] Get the longest side of each room in set B;

[0038] If the room is marked as the mth level monitoring area, the longest side of the room is divided into m equal parts to generate m sub-areas;

[0039] Get the geometric center of each sub-area, take the floor of the room as the bottom surface, connect the midpoint of the length and the midpoint of the width respectively, and mark the point where the two connecting lines intersect as the best monitoring point;

[0040] According to the room sample set Q, all the best monitoring points in each room are obtained to form a monitoring point set W.

[0041] Optionally, the wireless signal coverage monitoring strategy is to obtain the coverage range of the wireless signal emitted by each wireless access point, divide the coverage area, and generate a signal coverage map, including:

[0042] Setting a first signal strength threshold C and a second signal strength threshold V;

[0043] Wherein the first signal strength threshold C> the second signal strength threshold V;

[0044] According to the monitoring point set W, the signal area of ​​all elements in the set W is obtained;

[0045] The signal areas of all elements in the set W are divided by the first signal strength threshold C and the second signal strength threshold V, and the division rule is:

[0046] The monitoring point is taken as the center of the circle;

[0047] The distance from the monitoring point to the weakest point of the wireless signal strength emitted from the monitoring point is taken as the radius;

[0048] Draw a circular area according to the center position and radius length;

[0060] According to the coverage area set N, a first screening strategy is performed on the coverage area;

[0061] The first screening strategy is:

[0062] If there is a weak signal area in the coverage signal area of ​​the coverage area, then the coverage area is removed from the set N;

[0066] Set the coverage area overlap Y;

[0067] The coverage area overlap is used to obtain the number of repetitions of signal intensity areas radiated by other monitoring areas within the coverage signal area;

[0068] For example, if the overlap is 1, it means that within the coverage signal area, there is only one radiation signal strength in the remaining areas;

[0069] According to the set of coverage areas N after the first screening, if there is only a strong signal area in the coverage signal area of ​​the coverage area, and the corresponding coverage area overlap Y≥1, then the coverage area is retained;

[0070] If there is only a medium signal area in the coverage signal area of ​​the coverage area, and the corresponding coverage area overlap Y ≥ 3, then the coverage area is retained;

[0072] Optionally, optimizing the placement of the wireless access point according to the coverage area set N after the second screening includes:

[0073] Obtain the corresponding monitoring area in the coverage area set N;

[0074] Remove the wireless access points in the monitoring area.

[0075] The present invention has the following beneficial effects:

[0076] 1. The whole process simulation method of the power grid infrastructure project ensures comprehensive network coverage monitoring by setting the monitoring area and defining it as the area of ​​each room on the floor. By generating and numbering the room sample set Q, managing each room on the floor, setting the room area threshold T and classifying the rooms, the room samples are divided into the first and second monitoring areas, and the rooms with larger areas in the second monitoring area set B are further classified. The best monitoring points are set and the monitoring point set W is formed. The test strategies including the preprocessing strategy, the wireless signal coverage monitoring strategy and the wireless access point optimization strategy are executed. The wireless access points are installed at the monitoring points through the preprocessing strategy to provide a basis for the transmission of wireless signals. The wireless signal coverage monitoring strategy obtains the coverage range of the wireless signal and generates a signal coverage map, which can intuitively display the network coverage status on the floor. The wireless access point optimization strategy optimizes the placement of the wireless access points according to the signal coverage map to further improve the quality and efficiency of network coverage.

[0077] 2. The whole process simulation method of the power grid infrastructure project can realize the division of monitoring areas of rooms of different area ranges by subdividing the room samples in the second type of monitoring area set B, and divide the room samples into second-level, third-level and m-th-level monitoring areas according to the size of the area. By setting different monitoring area levels, network optimization resources can be more reasonably allocated according to the area of ​​the house. For example, for a larger room, more wireless access points may be required to ensure the quality and stability of network coverage.

[0078] 3. The whole process simulation method of the power grid infrastructure project obtains the length and width of each room in the room sample set Q, calculates the geometric center of each room in the first type of monitoring area set A, determines the most suitable location for setting monitoring points in the room, provides the best signal coverage effect, connects the midpoints of the length and width of the room to form vertical lines E and R, and determines the point where these two vertical lines intersect as the best monitoring point to ensure that the placement of the wireless access point maximizes the coverage range, and the best monitoring points are numbered and formed into a monitoring point set W. Wireless access points are installed at the best monitoring points to ensure effective coverage of wireless signals and optimization of network quality. This optimized monitoring point setting helps reduce signal dead spots and improve users' network experience.

[0079] 4. The whole process simulation method of the power grid infrastructure project is to classify the room samples in the second type of monitoring area set B, divide the longest side of each room into equal parts, generate multiple sub-areas, and ensure that in larger or complex-shaped rooms, wireless access points are set in the sub-areas respectively, so that the coverage of wireless signals is more uniform.

[0080] 5. The whole process simulation method of the power grid infrastructure project sets the first signal strength threshold C and the second signal strength threshold V, takes the monitoring point as the center of the circle, and draws a circular area with the length of the weakest point of the wireless signal strength as the radius, which intuitively represents the coverage of the wireless signal. By measuring and dividing the wireless signal strength, the strong signal area, the medium signal area and the weak signal area are identified, forming a basis for drawing the wireless signal map.

[0081] 6. The whole process simulation method of the power grid infrastructure project marks the coverage area in the signal coverage map, which can identify which areas have been covered by the signals of the adjacent monitoring points. This marking helps to find potential redundant coverage. By forming a set of coverage areas N, the first screening strategy is implemented to eliminate those coverage areas with weak signal areas and retain the coverage areas with strong or medium signal areas to ensure that the network quality of these areas is maintained or further improved. This retention strategy helps to maintain the overall performance of the network. The second screening strategy can further optimize the set of coverage areas N.

[0082] 7. The whole process simulation method of the power grid infrastructure project sets the coverage area overlap Y to quantitatively evaluate the signal coverage overlap between different monitoring areas, retains the coverage areas with strong signal areas and overlap Y ≥ 1, and sets the retention condition of overlap Y ≥ 3 for the coverage areas with only medium signal areas. Through the coverage area set N after the second screening, the placement of wireless access points is optimized, and the wireless access points are removed in the corresponding monitoring areas in the coverage area set N to reduce the overlap and conflict of signal coverage and avoid waste of resources.
