Description

Technical Field

[0001] This invention belongs to the field of highway road patrol and supervision technology, and relates to a supervision system and method for highway road patrol. Background Technology

[0002] The official opening of the Beijing-Taipei Smart Expressway, which utilizes technologies such as BeiDou positioning, 5G, big data, the Internet of Things, cloud computing, high-precision maps, and artificial intelligence, signifies that the digitalization and intelligentization of expressway operation and management have become a popular development direction in the industry. While information technology brings convenience to management, the amount of data generated is also growing explosively. How to extract effective data for statistical analysis poses a significant challenge for expressway operators.

[0003] Road patrol is a crucial method for proactively identifying problems in the daily management of highways. The frequency of patrols, the coverage of patrolled sections, and the allocation of time all impact the quality of patrols, which is also an important indicator for evaluating the performance of operating units. Currently, road patrol management is limited to recording and summarizing travel information, failing to provide targeted statistical analysis of patrol coverage and time allocation. Therefore, there is an urgent need for a patrol method that can provide a dynamic basis for adjusting road management regulations. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a supervision system and method for highway road patrol, providing highway operators with a basis for supervising the integrity of road patrol coverage and the rationality of time allocation, thereby improving the operation and management level of highways.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Option 1: A monitoring system for highway road patrol, including a road patrol spatiotemporal map display unit and a road patrol scoring unit;

[0007] The road patrol spatiotemporal map display unit includes a grid division module, a patrol frequency module, and a patrol time module. The grid division module is used by the operating unit to divide road segments for refined management, including marking the starting point of each grid with a station number. The patrol frequency module displays the total number of patrols for each grid on that day. The patrol time module displays the start and end times of each patrol for each grid, reflecting the time allocation for patrols on that day.

[0008] The road patrol scoring unit includes a patrol frequency scoring module and a coverage scoring module; wherein, the patrol frequency scoring module is used to calculate the patrol frequency score, which serves as the scoring criteria for road patrol frequency; the coverage scoring module is used to calculate the coverage score, which serves as the basis for judging the full road patrol coverage rate.

[0009] Furthermore, the road patrol spatiotemporal map display unit forms a two-dimensional coordinate system with space as the horizontal axis and time as the vertical axis, displaying information such as patrol time, patrol grid, and number of patrols; the start and end points of the patrol are connected to form a straight line, the slope of the straight line represents the vehicle speed during the patrol, the position of the straight line represents the time allocation of the road patrol, and the number of straight lines represents the number of patrols.

[0010] Furthermore, in the road patrol spatiotemporal map display unit, the horizontal axis of the two-dimensional coordinate system represents the road segment details, and the scale points represent the road station numbers. The interval between two scale points is a grid.

[0011] Furthermore, the patrol frequency score is obtained by calculating the sum of the "single vehicle patrol frequency" reported by each patrol vehicle of the operating unit, and is used as an evaluation standard for road patrol frequency; the coverage score module is obtained by statistically analyzing the patrol frequency of each grid and is used as a basis for judging the full road patrol coverage rate.

[0012] Furthermore, the road patrol scoring unit calculates the patrol frequency score and coverage score according to the scoring rules, and the sum of the two is the road patrol score for the day.

[0013] Furthermore, the formula for calculating "number of patrols per vehicle" is: Number of patrols per vehicle = (patrol mileage per vehicle / total mileage of road sections under the jurisdiction of the operating unit) × vehicle speed coefficient.

[0014] Option 2: A monitoring method for highway patrols, specifically including the following steps:

[0015] S1: Patrol personnel enter road patrol information, and the system stores this data in the database;

[0016] S2: The background periodically accesses the database. When new road patrol information is entered into the database, the road patrol spatiotemporal map unit calls the interface to retrieve the record.

[0017] S3: Obtain information such as grid name, start and end station numbers, patrol time, patrol vehicle and license plate number, and calculate the speed of the vehicle during patrol;

[0018] S4: Mark all information on the spatiotemporal diagram display unit;

[0019] S5: Within the set time, the road patrol scoring module reads all road patrol records from the database for the day and performs statistics;

[0020] S6: Calculate the number of patrols and the coverage score according to the scoring rules, and sum the two to get the road patrol score for the day.

[0021] S7: Display the results on the front-end page.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) Wide applicability. This invention is described using highway operation and management as a scenario, and is applicable to various management scenarios that require inspection and proactive problem discovery.

[0024] (2) The results are intuitive. This invention displays the spatial and temporal coverage in the form of a two-dimensional coordinate graph, which is highly visual; it quantifies the number of inspections and coverage by the operating unit, and the results are clear and easy to understand.

[0025] (3) High real-time performance. In this invention, the spatiotemporal map of the patrol is updated in real time as front-line workers input the road patrol information, and the situation is displayed on the two-dimensional coordinate map in a timely manner. The road patrol scoring function reads relevant records and performs calculations within a set time each day.

[0026] Other advantages, objectives, and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination, or may be learned from practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0031] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please see Figures 1-3 , Figure 1 As a monitoring system for highway road patrol, such as Figure 1 As shown, this includes a road patrol spatiotemporal map unit and a road patrol scoring unit. The road patrol spatiotemporal map unit includes a grid division module, a patrol frequency module, and a patrol time module; the road patrol scoring unit includes a patrol frequency score module and a coverage score module.

[0033] The road patrol spatiotemporal map uses space as the horizontal axis and time as the vertical axis to form a two-dimensional coordinate system, displaying information such as the time of road patrols, the grid of vehicle patrols, and the number of road patrols. Connecting the starting points of the patrols forms a straight line, the slope of the line represents the vehicle speed during the patrol, and the position of the line represents the allocation of road patrol time.

[0034] The daily road patrol score calculation method is based on a comprehensive consideration of both the cumulative number of patrols conducted by all vehicles of the operating unit and the coverage of the assigned road sections. Detailed scoring rules were designed to ensure the objectivity and fairness of the results. The spatiotemporal map of the road patrol and the road patrol score are mutually verified and complementary.

[0035] During system operation, the backend periodically accesses the database. When new road patrol information is entered into the database, the spatiotemporal map unit promptly calls the interface to retrieve the record and marks it on the spatiotemporal map according to the start and end station numbers and patrol time. The road patrol scoring unit then reads all road patrol records from the database for the day within a set time period, performs statistical calculations, and finally sends the obtained score to the front end for data updating and display on the browser page. The detailed process is as follows:

[0036] The workflow of the road patrol spatiotemporal map display unit, such as... Figure 2 As shown:

[0037] S1: Patrol personnel enter road patrol information, and the system stores this data in the database.

[0038] S2: The background periodically accesses the database. When new road patrol information is entered into the database, the road patrol spatiotemporal map unit calls the interface to retrieve the record.

[0039] S3: Obtain information such as grid name, start and end station numbers, patrol time, patrol vehicle, and license plate number, and calculate the vehicle speed during patrol.

[0040] S4: Mark all information as straight lines on the spacetime graph.

[0041] The workflow of the road inspection scoring unit, such as Figure 3 As shown:

[0042] S5: Within the set time, the road patrol scoring unit reads all the road patrol records of the day from the database and performs statistics.

[0043] S6: Calculate the number of patrols and the coverage score according to the scoring rules, and sum the two to get the road patrol score for the day.

[0044] S7: Display the results on the front-end page.

[0045] The road patrol time-space map unit provides "Operating Unit Name" and "Start and End Time" selection options, allowing managers to select different operating units and time intervals to view the results.

[0046] The steps for calculating the road patrol score of highway operation and management units are as follows:

[0047] Step 1: Calculate the number of patrols per vehicle.

[0048] Number of patrols per vehicle = (Patrol distance per vehicle / Total mileage of road sections under the jurisdiction of the operating unit) × Vehicle speed coefficient;

[0049] in:

[0050] (1) Single vehicle patrol mileage = sum of grid mileage reported by the vehicle;

[0051] (2) The vehicle speed coefficient (K) is calculated based on the vehicle’s average speed (V).

[0052] Step 2: Calculate the total number of daily inspections (M) for the operation and management unit.

[0053] Total daily patrol count = the sum of the "number of patrols per vehicle" reported by each patrol vehicle.

[0054] Step 3: Calculate the "Patrol Frequency Score" (C1).

[0055] The "Patrol Frequency Score" (C1) is calculated based on the "Total Daily Patrol Frequency" (M).

[0056] Step 4: Calculate the “Coverage Score” (F).

[0057] The "coverage score" (F) is calculated based on the number of daily patrols reported for each grid. The calculation process is as follows:

[0058] (1) Calculate the “grid average score”;

[0059] (2) Calculate the “single grid score”;

[0060] (3) Calculate F = the sum of the scores of each “single grid”.

[0061] Step 5: Calculate the daily road patrol score of the operating unit = C1 + F.

[0062] As a preferred embodiment, the system of this invention can be implemented using the Spring Boot + Mybatis + Vue framework, employing a layered architecture design. The system frontend, based on the Vue framework, sends requests to the backend for data interaction and displays the results on the browser page. The system backend integrates resources with the database through the Spring Boot and Mybatis frameworks, serving as the data layer technology to interact with the MySQL database and perform reading operations on road patrol records from the database.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
