[0001] This invention relates to the field of computer technology, specifically to highway toll collection technology, and more specifically to a method and related equipment for converting a highway network toll collection system based on a topology graph. Background Technology

[0002] Highway toll collection typically uses toll stations as nodes, dividing the highway network into several minimum toll units. Generally, the toll system needs to identify entry and exit toll stations along the route, then automatically connect the highway network routes between the entry and exit toll stations, match the toll units along the way, and finally accumulate the data to calculate the highway toll. Currently, customizing toll rates for each road segment requires personnel to convert the route data of the segment into network toll parameters according to the approved toll rate standards and highway network technical standards. This conversion process is complex, labor-intensive, and prone to errors. Summary of the Invention

[0022] The highway topology map is rendered based on the filled toll unit rate parameters, the filled toll station rate parameters, the first connection relationship, the second connection relationship, and the third connection relationship.

[0023] Furthermore, before rendering the highway topology map based on the filled toll unit rate parameters, the filled toll station rate parameters, the first connection relationship, the second connection relationship, and the third connection relationship, the method further includes:

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] It should be noted that the terms "comprising" and "having," and any variations thereof, in the embodiments and accompanying drawings of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices.

[0045] It is understood that the terms "first," "second," etc., used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first connection relationship may be referred to as a second connection relationship, and similarly, a second connection relationship may be referred to as a first connection relationship. Both the first connection relationship and the second connection relationship are connection relationships, but they are not the same connection relationship.

[0046] In the current highway network toll collection system, a highway is divided into multiple toll units based on its toll attributes. Each toll unit has an independent toll standard. During toll collection, the system breaks down the vehicle's actual travel path into a sequence of toll units, which consists of toll units connected sequentially along the travel path. The toll for a single trip is the sum of the toll standards of all toll units in that sequence. Toll units are directional, containing a clearly defined start and end point. For example, a toll unit with start point A and end point B is a different unit from a toll unit with start point B and end point A. There are connectivity relationships between toll units. A vehicle can only legally pass through and form a valid path if the end point of toll unit A is connected to the start point of toll unit B; otherwise, the path is invalid.

[0047] Typically, the connections between toll collection units on the main line of a highway are relatively simple, while those at interchanges are more complex. A tollbooth entrance connects to the starting point of a toll collection unit, and a tollbooth exit connects to the ending point. Therefore, any valid vehicle route consists of an entrance tollbooth, a series of sequentially connected intermediate toll collection units, and an exit tollbooth. Most toll collection units are equipped with toll gantries. When a vehicle passes through, the gantry system writes its passage information and toll records in real time to the vehicle's onboard medium (primarily ETC devices and CPC cards).

[0048] For a highway network toll collection system, the toll collection basis for the entire system is the highway toll rate parameter. This toll rate parameter can be composed of the following core elements: toll station information, toll units and their corresponding toll standards, connectivity between toll units, connection relationship between toll stations and toll units, toll gantries and their respective toll units, and other relevant data.

[0049] Currently, the process of creating highway toll rate parameters mainly involves manual analysis based on road design drawings to extract toll stations, toll units, gantries, toll standards, and various connection relationships (such as between units and between stations and units). This results in basic data such as toll station lists, toll unit lists, gantry lists, toll standard tables, and connection relationship tables. Finally, this data is entered into the system to generate complete toll rate parameters. This process is labor-intensive and prone to errors.

[0050] This application discloses a method and related equipment for model conversion of highway toll collection networks based on topology graphs, which can improve the efficiency and accuracy of generating target toll rate information. These will be described in detail below.

[0051] Please see Figure 1 , Figure 1 This is an application scenario diagram of a topology-based model conversion method for highway toll networks disclosed in this application. The topology-based model conversion method for highway toll networks is applicable to electronic device 101, which may include, but is not limited to, mobile phones, tablets, laptops, PCs (Personal Computers), etc., and this application embodiment does not impose any limitations. Electronic device 101 can obtain basic road segment information and toll rate standard information, generate a highway topology map based on the basic road segment information and toll rate standard information through a toll rate reporting model, and infer target toll rate information based on the highway topology map.

[0052] Figure 2 This is a flowchart illustrating a method for converting a highway toll network model based on a topology graph, as disclosed in an embodiment of this application. Figure 2The described topology-based model transformation method for highway toll collection networks is applicable to the aforementioned electronic equipment. For example... Figure 2 As shown, the model transformation method for the highway toll network based on the topology graph may include the following steps:

[0053] Step S201: Obtain basic road segment information and toll rate standard information.

[0054] In some embodiments, basic road segment information can be used to describe the connectivity of each road segment, and toll rate information can be used to describe the toll mileage and toll rate corresponding to multiple toll units and toll stations approved by government departments. This toll rate information can be stored in the electronic device in tabular form, without specific limitations. Users can directly import basic road segment information and toll rate information and store them in advance in the electronic device, enabling the electronic device to directly obtain these information. Optionally, users can also directly import highway design drawings into the electronic device, allowing the device to recognize the highway power design drawings and thus obtain basic road segment information.

[0055] As an optional implementation, after acquiring basic road segment information and toll rate standard information, the electronic device can perform an integrity check on the basic road segment information and toll rate standard information. If missing information is detected in the basic road segment information or toll rate standard information, a corresponding prompt message is generated, and new basic road segment information and new toll rate standard information are acquired again. The basic road segment information can contain data from multiple road segments, which can be used to describe the connection between the start and end points of the corresponding road segments. The integrity check of the basic road segment information can check whether the data of each road segment is complete. For example, if it is detected that a road segment only contains the start point A and not the end point, or if the connection between the end point of the road segment cannot be deduced based on reasoning, then the road segment information can be determined to have missing information. The toll rate standard information contains multiple toll rate parameters and the mapping relationship between the target toll mileage and the corresponding toll rate parameters. The target toll mileage can be the minimum mileage of a toll segment on a highway. For example, a highway can contain multiple target toll mileages. To calculate the toll rate on that highway, all target toll mileages on the highway can be superimposed to obtain the toll rate for that highway. Performing a completeness check on toll rate information can involve verifying whether all road segments included in the toll rate information have corresponding toll rate parameters. For example, if road segment A is detected in the toll rate information, but no corresponding toll rate parameter is identified, then it can be determined that the toll rate information is missing.

[0056] If the electronic device detects that there is missing information in the basic road segment information or toll rate information, it will generate a corresponding prompt message. The user can fill in the new basic road segment information and the new toll rate information according to the prompt message, so that the electronic device can re-acquire the new basic road segment information and the new toll rate information.

[0057] The electronic device performs integrity checks on the basic road segment information and toll rate standard information. If any missing information is detected in the basic road segment information or toll rate standard information, a corresponding prompt message is generated, and new basic road segment information and new toll rate standard information are re-acquired. This ensures the integrity of the basic road segment information and toll rate standard information, thereby providing a technical basis for generating target toll rate information based on the basic road segment information and toll rate standard information through the toll rate reporting model.

[0058] Step S202: Generate a highway topology map based on road segment basic information and toll standard information using the toll rate reporting model.

[0059] Step S203: Based on the highway topology map, the target toll rate information is deduced.

[0060] In some embodiments, the highway topology map is a digital road network topology map that integrates the road network structure and tolling rules. Electronic devices can use a rate reporting model to obtain toll unit rate parameters, toll station rate parameters, a first connection relationship, a second connection relationship, and a third connection relationship based on basic road segment information. The first connection relationship describes the connection relationship between toll stations and toll units; the second connection relationship describes the interconnection relationship between road segments; and the third connection relationship describes the connection relationship between various toll units. The electronic devices then associate the toll unit rate parameters, toll station rate parameters, first connection relationship, second connection relationship, and third connection relationship with the rate standard information to generate the highway topology map.

[0061] The electronic device can dynamically associate and match the elements of the aforementioned toll unit rate parameters, toll station rate parameters, first connection relationship, second connection relationship, and third connection relationship with preset rate standard information. The toll unit rate parameters may include the toll unit number, vehicle type coefficient, discount rules, etc., and the toll station rate parameters may include the toll station number, vehicle type coefficient, discount rules, etc. The toll unit rate parameters and toll station rate parameters can be stored in the form of data tables in a database, and ultimately rendered into a highway topology map, forming a computable tolling rule library covering the entire road network.

[0062] The toll rate reporting model first performs structured analysis on the input road segment basic information, extracting core road network entities, namely toll units and toll stations, and simultaneously establishing three key connection relationships describing the topological relationships between entities. Specifically, the first connection relationship defines the subordinate and access paths between a toll station and each toll unit within its jurisdiction; the second connection relationship defines the physical interconnectivity of different road segments (such as turning connections achieved through interchanges); and the third connection relationship focuses on revealing the direct adjacency or traffic continuity between various toll units. Subsequently, the toll rate reporting model uses these identified toll unit, toll station entities, and the three connection relationships to establish toll unit rate parameters for toll units and toll station rate parameters for toll stations. Finally, through this refined entity-relationship-parameter coupling process, the toll rate reporting model can generate a complete and information-rich highway topology map. The core value of a highway topology map lies in the integration of its target toll information. It not only presents the physical architecture of the road network intuitively, but also provides a solid data foundation for accurate route identification, dynamic toll calculation, and efficient clearing and settlement by binding toll rules to specific toll units and their connections.

[0063] The electronic equipment uses a rate reporting model to obtain toll units, toll stations, first connection relationships, second connection relationships, and third connection relationships based on basic road segment information. The first connection relationship describes the connection relationship between toll stations and toll units, the second connection relationship describes the connection relationship between road segments, and the third connection relationship describes the connection relationship between various toll units. The toll units, toll stations, first connection relationships, second connection relationships, and third connection relationships are associated with the rate standard information to generate a highway topology map.

[0064] Through automated modeling and intelligent association mechanisms, the overall efficiency of the highway toll collection system has been significantly improved. On the one hand, it greatly reduces the cycle and cost of traditional manual configuration, enabling rapid deployment and dynamic maintenance of road network parameters; on the other hand, it accurately constructs a highway topology map of toll units, stations, and multi-dimensional connections, completely avoiding manual input errors and ensuring the absolute reliability of toll calculation. Simultaneously, it endows the highway toll collection system with highly flexible scalability, seamlessly adapting to iterative updates to the road network structure, thereby fully supporting the intelligent upgrade of the highway's full-path accurate tolling system.

[0065] Furthermore, the electronic equipment can extract basic information about road segments to identify multiple road segment model units, toll station model units, and interchange model units; based on the road segment model units, it can segment into multiple toll units and establish toll unit rate parameters corresponding to each toll unit; based on the toll station model units, it can segment into multiple toll stations and establish toll station rate parameters corresponding to each toll station; based on the multiple toll unit rate parameters, it can establish a third connection relationship; and based on the toll unit rate parameters of the toll station model units and interchange model units, it can deduce the first and second connection relationships.

[0066] Furthermore, the electronic equipment can infer the first connection relationship based on the toll unit rate parameters; infer the connectivity of the toll station interchange through the interchange model unit; and infer the second connection relationship based on the toll unit rate parameters.

[0067] In other words, the toll rate reporting model can be composed of road segment model units, toll station model units, and interchange model units. The road segment model unit can define the road segment orientation and toll station layout; the toll station model unit can define the toll station entry and exit characteristics; and the interchange model unit can connect adjacent toll segments. Toll units are segmented from the road segment model unit based on the road segment toll station settings and interchange settings. These segmented toll units are then used to construct a third connection relationship based on the physical connectivity of the main line and interchanges. This is combined with the toll station model unit and the road segment model unit to infer and construct a first connection relationship, and finally, combined with the road segment model unit and the interchange model unit, to infer and construct a second connection relationship.

[0068] In some embodiments, the electronic device can fill in the toll unit rate parameters according to the toll mileage and toll standard corresponding to each of the multiple toll units to obtain the filled toll unit rate parameters; fill in the toll station rate parameters according to the toll mileage and toll standard corresponding to each of the multiple toll stations to obtain the filled toll unit rate parameters; and render a highway topology map based on the filled toll unit rate parameters, the filled toll station rate parameters, the first connection relationship, the second connection relationship, and the third connection relationship.

[0069] In other words, the electronic device can establish a mapping relationship between the segmented toll units and the toll mileage and toll standard corresponding to the toll units approved by the government, as well as a mapping relationship between the toll stations and the toll mileage and toll standard corresponding to the toll stations approved by the government. It can also process the generated toll units, toll stations and their connection relationships, and toll standards into a standardized rate format, thereby completing the production of rate parameters, obtaining target rate information, and mapping this target rate information onto the highway topology map to obtain the highway topology map.

[0070] In some embodiments, the electronic device can directly deduce the target toll rate information based on the highway topology map. The electronic device can dynamically track the route and calculate the toll rate on the highway topology map based on the vehicle's actual or planned travel path. Further, the electronic device can accurately reconstruct the vehicle's actual travel trajectory in the road network, i.e., the sequence of toll units traversed and their connection methods, based on the vehicle's entrance and exit toll station information, combined with the connection relationships defined in the highway topology map, particularly the second connection relationships describing the interconnectivity of road segments and the third connection relationships describing the adjacency relationships between toll units. Subsequently, for each toll unit on this actual travel trajectory, the electronic device automatically associates its bound toll rate parameters; simultaneously, it analyzes the second connection relationships triggered by the vehicle's turning behavior at key nodes in the path, associates and applies the corresponding turning surcharge rules; in addition, the start and end point information of the path is also associated with the first connection relationships to confirm the start and end range of the toll calculation. Finally, the electronic device integrates the basic fees of all toll units on the path, the surcharges incurred due to specific turns, and other applicable rules, such as vehicle type differences and preferential policies, and performs summation or logical operations to deduce the target toll rate information payable for the vehicle's actual or planned travel path. Similarly, the target toll rate information for each road segment can be deduced, allowing users to quickly find the corresponding target toll rate information for each road segment. Electronic devices can directly deduce target toll rate information based on the highway topology map, providing strong technical support for refined operation management and transparent cost display for users in complex road network environments.

[0071] Figure 3 This is a schematic diagram of the process for generating target rate information in one embodiment, such as... Figure 3 As shown, the electronic device can set up road segment model units, toll station model units, and road segment connectivity models, and divide toll units. Based on the divided toll units and toll stations, it can infer the connectivity relationship of the mainline toll units, and infer the connection relationship between toll stations, ramp toll units, and mainline toll units, and map toll units and toll standards to generate target toll rate information.

[0072] In this embodiment, the electronic device can acquire basic road segment information and toll rate standard information; generate a highway topology map based on the basic road segment information and toll rate standard information through a toll rate filling model; and infer the target toll rate information based on the highway topology map. It can directly generate a highway topology map based on the acquired basic road segment information and toll rate standard information through the toll rate filling model, and can directly infer the target toll rate information based on the highway topology map. This eliminates the need for personnel to convert road segment data into network toll parameters according to highway network technology standards, thereby greatly reducing the conversion work for personnel and minimizing errors caused by manual filling, thus improving the efficiency and accuracy of generating target toll rate information.
