Description

TECHNICAL FIELD

[0001] The present application relates to the field of address coding and logistics information technology, and in particular to a unique urban and rural address coding method and system based on the extension of the existing postal code system and ultimately subdivided to the door, floor and room of a building. BACKGROUND

[0002] Postal code is an important tool for postal departments to realize automatic sorting of mail and improve delivery efficiency. Since 1986, China has implemented the "four-level six-code" system of postal code. However, the traditional postal code is only accurate to the delivery area branch (such as townships, streets), and cannot identify the final delivery point (such as specific building, room), resulting in the need for manual judgment by text address in the "last mile", which is inefficient and prone to errors. To solve this problem, the industry has proposed various fine-grained address coding schemes. For example, the State Post Bureau promotes the "General Delivery Address Coding Rules" national standard, which includes a national code, a satellite navigation system code, and a delivery location code, which can accurately locate to a centimeter-level address. In addition, there are concepts such as "personal address ID" and "super postal code", which aim to assign a unique code to an individual or address. The existing schemes have the following shortcomings: poor compatibility with existing systems: Some new coding systems (such as coding based on geographic coordinates) have poor compatibility with the traditional postal code system that has been deeply integrated into various aspects of society, resulting in high promotion costs. Urban and rural fragmentation and lack of precision: Most schemes do not fully consider the differences in urban and rural address structures, making it difficult to cover the rural "province-county-town-village-group" and urban "city-district-street-community-building" hierarchy with the same logic. In particular, even if the scheme identifies a "house", the code is often the sequential number of the house, which does not intuitively reflect the spatial location of the house in the building (such as the number of doors and floors), making it difficult for manual identification and path planning, especially for robot delivery identification and path planning. Memory and usage threshold: Some high-precision codes have a long number of digits and lack intuitive logic, making it difficult for manual memory, oral transmission, or quick filling. Therefore, there is a need for a unified urban and rural address coding scheme that can inherit existing postal code infrastructure, seamlessly extend downward, and intuitively reflect the spatial location of the building. SUMMARY

[0003] The purpose of the present application is to overcome the shortcomings of the prior art and provide a unified urban and rural address coding method and system based on the extension of the postal code and subdivided to the door, floor and room of a building. This method achieves "one house, one address, one code" by structuring and spatially extending the existing postal code, and the code itself can intuitively indicate the spatial location, effectively solving the problem of accurate addressing without delivery coding, while maintaining compatibility with the traditional postal system. TECHNICAL SCHEME

[0004] To achieve the above object, the present application proposes the following technical scheme: The core lies in standardizing and structuring expansion of the existing 6-bit basic postcode. The expansion part adopts a hierarchical structure, and two sets of parallel detailed code rules are designed according to different address characteristics of rural and urban areas. The final room code of urban address adopts an innovative three-segment structure of "building door-floor-house door", and finally forms a long, unique and spatially indicative digital code.

[0005] Code structure. Basic part: the existing 6-bit "four-level six-code" postcode (for example: 100048 and 436318) is adopted, which itself contains province, city postal area, county, and delivery office information. Expansion part: rural address expansion: after the 6-bit basic code, "4-bit village-level code + 4-bit villager group code + 6-bit house code" are sequentially added. For example: "436318 00010002 000003". 436318 represents 43 Hubei Province, 6 postal area, 3 E'chun County, 18 Mafan Branch, 0001 village, 0002 villager group, and 000003 villager house. Urban address expansion: after the 6-bit basic code, "4-bit community / courtyard code + 4-bit building code + 6-bit room subdivision code" are sequentially added. Among them, the 6-bit room subdivision code is composed of "2-bit building door unit code + 2-bit floor code + 2-bit house door sequence code". For example: "100081 1234 0567 011208". 100081 represents Beijing Weigongcun Branch, 1234 courtyard (community), 0567 building, 1 door, 12 floor, and 08 house. If the building has only one unit door, it is represented as 001208. If there are semi-underground or underground rooms, DX is used to represent, such as 01D108, representing 1 door, 1 floor, and 08 number. If the courtyard is a government unit, the building and unit are all defaulted to 0000 000000. For example: 100037 01230000 0000. 100037 represents Beijing 37 Branch (Baiwanzhuang), 0123 is assumed to represent Beijing University of Business and Technology (Fucheng Road 33 Courtyard and Fucheng Road 11 Courtyard) government, and the school has a receiving room to uniformly process the distribution of mail from each department and office. For the government, after the University of Business and Technology, the building 0000 and the building door 000000 are defaulted. For the family courtyard, the east courtyard (Fucheng Road 11 Courtyard) and the west courtyard (Fucheng Road 33 Courtyard), after 0123, the building code is coded in the order of 0001 to 00xx, and each resident house is coded in six bits according to the building door floor and house number.

[0006] The scientific merits of the subdivided unit coding: The specially designed 6-digit subdivided unit coding (XX-XX-XX) of this invention has the following scientific and practical advantages: Intuitive spatial mapping: The coding structure completely corresponds to the physical spatial hierarchy of the actual building (building -> floor -> unit), making the coding itself a kind of "address map." Flexible default handling: For single-building structures, the building unit code can be uniformly set to "00," maintaining the uniformity of the coding structure while simplifying coding for common situations. Facilitating addressing and navigation: Even if it is their first visit, delivery personnel (or robots) or visitors can infer the approximate location and route to the destination simply by interpreting this code, significantly reducing the difficulty of addressing. Easy to remember and verify: The regular hierarchical structure is easier to remember and verbally transmit than completely random sequential numbers, and it is also easier to verify the format.

[0007] The system comprises: an encoding generation module, which automatically generates full codes conforming to the aforementioned rules based on address information; a data storage module (mapping relationship database), which stores the correspondence between full codes and standard text addresses, geographical coordinates, etc.; and an address service interface, which provides services such as encoding query, address parsing, and verification. Compared with existing technologies, this invention has the following significant advantages: High compatibility and smooth transition: Based on existing postal codes, it maximizes the use of existing infrastructure and social awareness. True "one code per household" and "spatial readability": Not only does it uniquely identify each household, but its innovative household coding structure allows the code itself to carry spatial location information, greatly improving the efficiency of manual or machine address searching. Unified urban and rural coding logic: Through two sets of parallel extension rules, it covers the address systems with huge urban and rural differences using the same coding concept. Scientific structure and strong practicality: The coding design fits the actual building layout, the default mechanism is flexible, and a good balance is achieved between accuracy and ease of use.

Figure 4 This is a structural block diagram of a unified urban and rural household address coding system provided in an embodiment of the present invention. Detailed Implementation

[0009] Example 1: Encoding Generation Method See Figure 1When a code needs to be generated for an address, the system first determines the corresponding 6-digit basic postal code by querying the national standard database or through user input. If it is a rural address, it further determines the administrative village, villager group, and housing unit, and retrieves the corresponding 4-digit and 6-digit codes from a pre-assigned code table, concatenating them in sequence. Figure 2 If it's a city address, the system continues to determine the city district, delivery office, community / residential compound, and building, obtaining the corresponding codes for each. Key steps: The system further determines the building unit, floor, and apartment door sequence number. For single-building structures, the building unit code is automatically assigned "00". Finally, a 6-digit apartment sub-code is generated according to the rule of "2-digit building unit code + 2-digit floor code + 2-digit apartment door code", completing the concatenation. Figure 3 ).

[0010] Example 2: System Application. See also Figure 4 The application of the system of this invention in logistics scenarios is as follows: The sender only needs to fill in the recipient's "full address code" (e.g., 100048 01 01 1234 0567 01 12 08) on the waybill. The courier company's sorting system reads this code. The system calls the address service interface, queries the mapping relationship database, parses the code into a complete text address and / or geographical coordinates, and sends it to the courier's handheld terminal. In addition to displaying the address and navigation, the terminal can also directly highlight the information "Door 01, Floor 12, Room 08" in the code. Even in unfamiliar neighborhoods, couriers can find the target directly and quickly, as if they knew the apartment number, without having to repeatedly check the vague text address description.

[0011] It should be noted that the allocation and management of codes at all levels can be collaboratively completed by the civil affairs, housing and construction, and postal departments at each level. A dynamic update mechanism needs to be established for the mapping database.
