Description

Technical Field

[0001] The present invention belongs to the technical field of underground parking, and particularly relates to a method for setting navigation coordinates and coordinate numbers in an underground parking lot. Background Art

[0002] With the acceleration of the urbanization process, as an important part of urban infrastructure, the scale of underground parking lots is expanding day by day, and the structure is becoming increasingly complex. However, due to the characteristics of enclosed space, complex structure, and insufficient light in underground parking lots, traditional navigation methods often have difficulty providing accurate and efficient guiding services, bringing many inconveniences to car owners. Therefore, it is particularly important to develop a high-precision and easy-to-operate underground parking lot navigation coordinate and number setting system.

[0003] Currently, underground parking lot navigation technology mainly relies on traditional signboards, maps, and the recently emerging intelligent navigation APPs. However, these technologies still have some deficiencies in practical applications:

[0004] Limitations of signboards and maps: Although traditional signboards and maps can provide certain navigation information, limited by their display methods and update speeds, they often cannot reflect the latest layout and parking space status of underground parking lots in real time. In addition, the clarity and readability of signboards and maps are also affected by factors such as environmental light and viewing distance.

[0005] Defects of intelligent navigation APPs: Although intelligent navigation APPs can provide more detailed and real-time navigation information, due to problems such as uneven or no signal coverage and limited positioning accuracy in underground parking lots, their navigation effects are often not satisfactory. Especially in multi-story parking lots, due to signal interference and occlusion between floors, positioning errors may further increase and navigation may be impossible.

[0006] The above information disclosed in the above background art section is only used to enhance the understanding of the background art of the technology described in this article. Therefore, the background art may contain certain information that is not prior art known to those skilled in the art in this country. Summary of the Invention

[0007] In order to solve the defects existing in the above prior art, the present invention proposes a method for setting navigation coordinates and coordinate numbers in an underground parking lot, which re-numbers the entry and exit sequences and structural relationships of each parking space, orientation, intersection, main passage, internal main road, and branch passage inside the parking lot, making it easier for car owners to understand and use quickly, simple and easy to remember, and easy to learn at a glance.

[0008] The technical solution adopted by the present invention is as follows:

[0009] A method for setting navigation coordinates and coordinate numbers in an underground parking lot, comprising the following steps:

[0010] a) Determine the orientation of the underground parking lot, confirm the basic center point, and roughly divide it into five sub - areas or partial direction sub - areas of east, south, west, north, and middle centered on this point. Each sub - area has a jurisdiction of approximately 90 degrees of angle, and at the same time, name the import and export channels within each sub - area;

[0011] b) Name each import and export channel. The naming rule is to place the orientation (east, south, west, north, middle) at the first place, and the serial number of the import and export channel (one, two, three, four, etc.) at the second place. The channel sorting is carried out in a clockwise direction;

[0012] c) Name the main channel. The main channel is the road extending from the channel entrance to the underground parking lot. The naming rule is to mark it with the orientation / serial number plus the word'main' and then the serial number / orientation;

[0013] d) Name the main channel and its navigation coordinate points. Navigation coordinate points are set at certain distances at positions such as on the main channel, at turning points, and at bifurcations, and are numbered starting from 01. When the number is insufficient, three - digit numbers are used for numbering. The naming rule includes orientation / serial number, main, orientation / serial number, and the number;

[0014] e) Name the branch channel and its navigation coordinate points. The branch channel is the channel bifurcated from the main channel. Its naming rule includes the naming of the main channel, the word 'branch', orientation / serial number, and the number. The navigation coordinate points on the branch channel start from the first one bifurcated from the main channel and are numbered 01;

[0015] f) Set the main - channel intersection points and branch - channel intersection points. The intersection points can be numbered from north to south according to the basement layout, or numbered irregularly or not numbered;

[0016] Furthermore, for some underground parking lots, the main channels cannot directly intersect, and are connected by some bridging channels. This bridging channel also conforms to the characteristics of the main channel, so its naming and numbering rules are the same as those of other main channels, but include the word 'inner main'.

[0017] Furthermore, for some underground parking lots, there are roads called single - branch channels that branch out from the main channel or branch channel and form independent areas that are not connected to other channels. Navigation coordinate points are also set at certain distances, and their numbering and naming methods are similar to those of other branch channels.

[0018] Furthermore, for multi - layer underground parking lots, the downhill channel from the first basement floor to the second basement floor is called 'negative two', and the downhill channel from the second basement floor to the third basement floor is called 'negative three', which are distinguished by orientation or serial number.

[0019] Furthermore, for underground parking lots with multi - layer structures, the coordinate and numbering methods of the main channels and branch channels on the second basement floor and the third basement floor, etc., are the same as those on the first basement floor, but the corresponding identifiers of 'negative two' or 'negative three' are added in front of the first - place direction representation.

[0020] Furthermore, at positions such as the turning and bifurcation of the branch channels, there are also marked the north, south, east, and west direction signs centered on this navigation point.

[0021] Furthermore, all the numbers of the navigation coordinate points are numbered with the numbers 0 - 9.

[0022] Furthermore, for one - way entrances, it is specifically noted as a one - way entrance at the entrance.

[0023] In summary, due to the adoption of the above - mentioned technical solution, the beneficial effects of the present invention are as follows:

[0024] After setting the coordinate points of the underground parking lot and the method of numbering the coordinate points in the present invention, the access sequence and structural relationship of each parking space, orientation, crossing, main channel, internal main road, and branch channel inside the parking lot are renumbered, enabling people to immediately have a basic understanding of their current position in the basement. In combination with the positions of other required navigation points, people looking for parking spaces or floor entrances can have a basic understanding of the relationship between the orientation, main roads, and branch roads in the basement and the terrain. The coordinate point closest to the parking space or the coordinate point of the floor entrance is the point that needs to be found in the navigation of this basement. Finding this coordinate point is equivalent to finding the parking space. This setting and numbering method maps the access sequence and structural relationship of the parking space, orientation, crossing, main channel, internal main road, and branch channel, which is very easy to understand and quickly use, simple to remember, and easy to learn at a glance.

[0030] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0031] Example 1

[0032] This embodiment provides a method for setting navigation coordinates and coordinate numbers for an underground parking lot. Figures 1-4 ,include:

[0033] a) Division and naming of underground parking lots:

[0034] First, we accurately confirmed the overall orientation of the underground parking lot and selected a core center point as a reference. Based on this center point, we scientifically divided the parking lot into five or partial direction partitions, each covering a range of 90 degrees. At the same time, to ensure that the entrance and exit channels in each area are easy to distinguish and identify, we clearly named these channels, and incorporated the orientation information into the naming to facilitate quick positioning by car owners.

[0035] b) Naming standards for entrances and exits:

[0036] The naming of the entrances and exits strictly follows the following rules: the direction (east, south, west, north) is the first part of the name, followed by the entrance and exit number (one, two, three, four, etc.), and the numbers increase in a clockwise direction. For example, "East One" represents the first entrance and exit from the east of the parking lot, and "East Two" represents the second entrance and exit from the east. The channel sequence strictly follows the clockwise direction and is clearly marked with numbers such as one, two, three, four, and five. For single-line entrances, we will specially indicate "single-line entrance" in a prominent position at the entrance to avoid confusion.

[0037] c) Main channel naming and numbering:

[0038] The main passage refers to the road that directly extends from the entrance and exit to the underground parking lot. Some main passages will immediately bifurcate into multiple roads after entering the basement. Since these roads are directly connected to the entrance, they are all regarded as main passages. The naming of the main passages incorporates orientation (east, south, west, north, middle) or numerical (one, two, three, four, five, etc.) information for easy distinction. For example, "East Second Main East" represents the main passage extending eastward from the second entrance in the east direction of the parking lot, and "East Second Main West" represents the main passage extending westward and close to this entrance.

[0039] d) Setting of navigation coordinate points for main passages:

[0040] At key positions such as on the main passage, at turning points, and at bifurcations, we have set up navigation coordinate points at certain intervals. The numbers of these coordinate points start from 01 until the exit or the intersection with other main passages. If the parking lot is large in scale, the numbering can start from 001 to ensure the continuity and uniqueness of the numbering. The numbering is carried out using the numbers 0 - 9. For example, "West First Main South 03" represents the third coordinate point on the main road extending southward from the first entrance in the west direction.

[0041] e) Naming and numbering of branch passages and their navigation coordinate points:

[0042] Branch passages refer to the roads that are not directly connected to the entrance and exit, but are indirectly connected through the main passage. For the situation where some parking lots have direct left and right bifurcations from the main passage, we use orientations or numbers such as east, south, west, north, one, two, etc. to number and distinguish the branch passages. At positions such as on the branch passage, at turning points, and at bifurcations, we have also set up navigation coordinate points at certain intervals. The numbers of these coordinate points start from the first one bifurcated from the main road and are numbered sequentially as 01, 02, etc. until they intersect with other main passages or branch passages. The numbering is also carried out using the numbers 0 - 9. For example, "South Main West 07 Branch East 05" represents the fifth coordinate point on the eastward branch passage bifurcated from the seventh coordinate point on the main passage extending westward from the south entrance of the parking lot. To facilitate the vehicle owner to quickly determine the orientation, we also mark the east, south, west, and north directions centered on this navigation point by spraying or other means at each bifurcation.

[0043] f) Naming and numbering rules for intersection points:

[0044] Main intersections refer to the intersection points generated by the intersection of the main passages entering the basement from each entrance and exit of the parking lot. The numbers of these intersection points can be numbered in an orderly manner from north to south according to the basement layout, or can be numbered in a random or unnumbered way. Branch passage intersections refer to the intersection points generated by the intersection of the branch passages in the basement, and their numbering rules are the same as those of the main intersections.

[0045] Embodiment 2

[0046] Special consideration has been given to those special situations where the main channels in underground parking lots cannot directly converge. To effectively connect these main channels, we have introduced the design of bridging channels. These bridging channels not only achieve the connection between the main channels, but also possess the key features of the main channels themselves. Therefore, in the navigation system, we have named them "inner main roads" and made corresponding markings and numberings for them.

[0047] On the inner main roads, we have also set up navigation coordinate points at established distances to ensure that car owners can accurately find the target positions. The numbers of these coordinate points strictly follow the numerical sequence from 0 to 9, ensuring the continuity and easy recognition of the numbers.

[0048] Taking "North First Main 12 Inner Main 03 Branch 06" as an example, this numbering details the navigation path of the car owner after entering the main channel from the first entrance and exit in the north of the parking lot. Specifically, "North First Main 12" means that the car owner has driven to the 12th navigation coordinate point on this main channel; "Inner Main 03" indicates that the car owner then enters the inner main road and drives to the 3rd coordinate point on this channel; and "Branch 06" further indicates that the car owner branches off at the 3rd coordinate point of this inner main road, enters the branch channel, and continues to drive to the 6th coordinate point on this branch channel.

[0049] This detailed numbering method not only provides clear navigation guidance for car owners, but also greatly improves the accuracy and practicality of the navigation system. In addition, we have also considered the special situations of multi-level underground parking lots and made corresponding adjustments and optimizations to the navigation coordinates and numbering methods to ensure that car owners can quickly and accurately find the target positions in any complex environment.

[0050] Example 3

[0051] Special attention has been paid to some special road types existing in underground parking lots - single-branch channels. These channels branch out from the main channels or branch channels and are characterized by not being connected to other channels, thus forming an independent area.

[0052] To ensure that car owners can accurately find these single-branch channels during navigation and reach the target positions smoothly, we have decided to also set up navigation coordinate points at certain distances on the single-branch channels. The establishment and naming methods of these coordinate points are consistent with those of other branch channels, that is, they are numbered using a numerical sequence and follow the established naming rules.

[0053] Specifically, the numbering and naming of individual channels will refer to the numbers of the main channels or branch channels they are connected to. For example, if an individual channel branches out from the main channel in the east direction, its number may be prefixed with "east" followed by a specific numerical number to represent the navigation coordinate points on that individual channel. Similarly, if an individual channel branches out from a certain branch channel, its number may be based on the number of that branch channel, plus a number indicating the internal position within the individual channel.

[0054] This numbering and naming method not only maintains the consistency and coherence of the entire parking lot navigation system but also helps vehicle owners quickly and accurately find the target location in a complex parking lot environment. By setting up navigation coordinate points for individual channels, we can ensure that vehicle owners do not get lost during driving, thereby improving parking efficiency and safety.

[0055] Embodiment 4

[0056] In the environment of a multi-level underground parking lot, in order to ensure that vehicle owners can accurately and efficiently find the target parking space or exit, we have specifically designed a set of navigation coordinate and numbering setting methods suitable for multi-level structures. The following is a detailed elaboration of this method:

[0057] I. Naming Rules for Channels in Multi-level Parking Lots

[0058] Naming of downhill channels:

[0059] The downhill channel leading from the first basement level to the second basement level is named "Negative Two".

[0060] The downhill channel leading from the second basement level to the third basement level is named "Negative Three", and so on.

[0061] To distinguish downhill channels in different positions or directions, directions (such as east, south, west, north) or serial numbers (such as one, two, three, four, etc.) can be used for further refined naming.

[0062] II. Coordinate and Numbering Methods for Multi-level Parking Lots

[0063] Coordinates and numbers for main channels and branch channels on the second basement level and below:

[0064] The coordinate and numbering methods for these levels are highly consistent with those of the first basement level to ensure the coherence and consistency of the entire parking lot navigation system.

[0065] The only difference is that the corresponding downhill channel name (such as "Negative Two" or "Negative Three") is added in front of the original first digit representing the direction or serial number (such as "East One" or "West Two").

[0066] Numbering example:

[0067] Taking "Negative Second Floor, Main Passage Westward Extension, 8th Navigation Coordinate Point with Southward Branch Passage, 6th Coordinate Point on the Branch Passage with Northward Branch Again, and 9th Coordinate Point on the Second Branch Passage as the Target Location" as an example, this numbering represents that at the 8th navigation coordinate point on the main passage extending westward from the entrance of the negative second floor east passage, a southward branch passage is generated. At the 6th coordinate point on this branch passage, a northward branch is generated again, and the 9th coordinate point on this secondary branch passage is the target location.

[0068] This numbering method clearly shows the complete path for the vehicle owner to enter the main passages, branch passages at each level from the downhill passage and finally reach the target location.

[0069] III. Navigation Advantages of Multi - level Parking Lots

[0070] Coherence: By maintaining the consistency of coordinate and numbering methods at each level, vehicle owners can more easily adapt to the environment of multi - level parking lots and reduce navigation difficulties caused by level changes.

[0071] Accuracy: Detailed numbering and naming rules ensure that vehicle owners can accurately find the target location, avoiding the embarrassment and inconvenience of blindly searching in the parking lot.

[0072] Efficiency: By providing clear and accurate navigation guidance for multi - level parking lots, vehicle owners can find parking spaces or exits faster, thus improving parking efficiency and safety.

[0073] In summary, the method for setting navigation coordinates and numbers in the multi - level underground parking lot provided in this embodiment has high coherence, accuracy and efficiency, providing a more convenient and comfortable parking experience for vehicle owners. At the same time, this method is also applicable to the underground parking lot environment with complex and multi - level structures, providing a more scientific and reasonable navigation solution for parking lot managers.

[0074] Embodiment 5

[0075] In the navigation system of underground parking lots or large complex buildings, in order to help navigators (such as vehicle owners, pedestrians, etc.) more intuitively and quickly understand the hierarchical and directional relationships between navigation points, we propose an innovative navigation point numbering system. This system visually represents the superior - subordinate or front - back relationships between navigation points and adjacent points by setting different background colors for the navigation point numbers.

[0076] I. Background Color Setting Rules

[0077] Blue background: Represents the sequence of navigation points coming from the entrance direction, and the number values are arranged in ascending order, starting from 01 and gradually increasing to 99. This color setting means that when a navigator stands at a navigation point with a blue background, if they need to go to a more "advanced" or more "distant" navigation point, they should choose to move in the direction of a larger number value.

[0078] Green background: Contrary to the blue background, the green background represents a sequence of navigation points with decreasing numerical values, i.e., gradually decreasing from 99 to 01. This color setting prompts the navigator that if they need to return to a "lower-level" or more "proximate" navigation point, they should choose the direction with a smaller numerical value.

[0079] II. Application of the Navigation Point Numbering System

[0080] Intuitiveness: Through simple color contrast, the navigator can quickly understand the relationship between the current navigation point and adjacent points without having to carefully read complex written instructions or maps, thus making correct navigation decisions.

[0081] Ease of use: Regardless of the cultural level or language background of the navigator, color, as a universal language, can be easily understood and accepted. This greatly improves the ease of use and popularity of the navigation system.

[0082] Flexibility: This system is not only applicable to underground parking lots but can also be widely used in large shopping malls, hospitals, airports, railway stations, and other places that require internal navigation. By simply adjusting the layout and numbering rules of the navigation points according to the specific environment, rapid deployment and application can be achieved.

[0083] The navigation point numbering system based on background color differentiation proposed in this embodiment provides clear and accurate navigation guidance for the navigator through intuitive color contrast and simple numbering rules. This system not only improves navigation efficiency but also reduces navigation difficulty, providing an effective solution to the navigation problems inside large and complex buildings such as underground parking lots.

[0084] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
