[0017] The present disclosure will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0018] Figure 1This is a flowchart 100 of some embodiments of the information board content security review and detection method disclosed herein. The information board content security review and detection method includes the following steps: Step 101: Monitor the network address of each information board to be delivered, receive the information playlist sent by the information publishing platform, and extract the information playback format information from the corresponding parsing library according to the model of each information board.

[0019] In some embodiments, the execution entity (e.g., a computing device) of the information board content security review and detection method can monitor the network addresses of each information board to be displayed, receive information playlists sent by the information publishing platform, and extract information playback format information from the corresponding parsing library according to the model of each information board. One information playback format corresponds to one information board. The network address can be an IP address. The information playback format information can include parameters such as the number of screens, text content, icons, colors, font size, number of characters, and scrolling speed. A TCP proxy service is started to monitor the IP addresses of the information boards and receive the information playlists from the publishing platform. The information publishing platform can be a platform that publishes road information. The information playlist can be the information to be displayed on each information board. The information board can be a highway variable message sign (traffic guidance screen). The model of the information board can represent its brand and model; different information boards support different playback format information. The information board can render and display the information according to the playback format information.

[0020] For example, the individual pieces of information in an information playlist may include: 1. Normal traffic information: Service notices (such as "Gas stations in service areas are open for business").

[0021] Real-time traffic conditions (e.g., "Heavy traffic, slow-moving traffic").

[0022] Weather information (e.g., “High temperature warning, G3K600-K650 trucks should pay attention to tire cooling”).

[0023] Safety warning signs (such as "Emergency lane, no occupation allowed, violators will be photographed").

[0024] Driving instructions (such as "Please turn on your headlights when entering a tunnel").

[0025] 2. Special road condition information: Traffic accidents (e.g., “G15K200+500 Truck overturned and blocked the second lane, slow down”).

[0026] Road construction / maintenance (e.g., "Milling of road surface in section K60-K70, occupying the left lane until May 10").

[0027] Traffic control (e.g., "Temporary control, dangerous goods vehicles are prohibited from passing through G19K950-K1000 until 16:00").

[0028] Station congestion / closure (e.g., "Exit XX is congested, please detour via G94").

[0029] Severe weather warnings (such as "Orange fog warning, visibility <50m on G10K100-K150, reduce speed and turn on lights").

[0030] 3. Major holidays or friendly reminders: Holiday greetings (such as "Happy Chinese New Year, and have a safe journey").

[0031] Special time period reminders (such as "No honking on G20K100-K120").

[0032] 4. Promotional Information: (For example, "During holidays, dangerous goods vehicles are prohibited from passing through all highway entrances").

[0033] Public service announcements (such as "Please do not litter, and work together to maintain the highway environment").

[0034] Optionally, before monitoring the network addresses of each information board to be displayed and receiving the information playlist sent by the information publishing platform, the above method further includes: The first step is to construct a knowledge graph containing information on each road segment, management information, review rules, and monitoring data formats. The aforementioned implementing entities can construct a knowledge graph containing road segment information, management information, review rules, and monitoring data formats. The second step is to convert the knowledge graph into vector data and store it in a vector database. The execution entity mentioned above can use Ollam's Embeddings model to convert the knowledge graph into vector data and store it in the Chromadb vector database.

[0035] It should be noted that: 1. Overview of Highways The XX section of Expressway A is an eight-lane dual carriageway with a roadbed width of 42.5 meters. The pavement is made of asphalt concrete, composed of multiple layers including fine-grained modified asphalt concrete, medium-grained asphalt concrete, coarse-grained asphalt concrete, cement-stabilized crushed stone, and low-dosage cement-stabilized crushed stone. Normally, the leftmost lane for cars has a speed limit of 100-120 km / h, the middle lane for mixed passenger and freight traffic has a speed limit of 80-100 km / h, and the rightmost lane for large trucks has a speed limit of at least 60 km / h.

[0036] This section of road has multiple toll stations to facilitate travel. RXX City W station has 20 lanes (8 inbound and 12 outbound), including ETC lanes, and is located at the intersection of A Expressway and C Avenue. D toll station is located at the intersection of D Road and A Expressway. T toll station is located on the South Third Ring Road in K District of XX City. The north entrance of the airport station is for vehicles heading towards the airport, while the south entrance only allows vehicles to enter, not exit. Y District station has a 6-inbound and 10-outbound design and is located in the southwest of Y Economic Comprehensive Experimental Zone of XX City. M station (M Road station) has 20 lanes (7 inbound and 13 outbound, including 8 ETC lanes, 4 inbound and 4 outbound), located at the intersection of A Expressway and M Road.

[0037] Regarding interchanges, interchanges have been built at the intersections of Expressway A and several important roads in XX city. Road B's entrances and exits utilize a double-trumpet interchange, with Road B crossing over and under Expressway A via elevated and ground levels. The interchange between Avenue C and Expressway A has 20 lanes (8 inbound and 12 outbound) and 7 ramps, including 3 overpasses of Avenue C and 2 underpasses of Expressway A. The interchange between Road D and Expressway A uses a double-trumpet interchange design, with a main line length of 1.195 kilometers, including 9 ramps, 2 ramp bridges, 1 main line bridge widening, 3 culverts, and 5 underpasses. The combined interchange of Expressway A, Provincial Highway 102, and Linked Avenue E is the largest of its kind in my country. The single-unit combined interchange adopts a turbine + single-trumpet + T-type combined interchange scheme. The intersection of E-Link Avenue and Provincial Highway 102 uses a turbine type, with E-Link Avenue crossing over Provincial Highway 102. The interchange between Expressway A and E-Link Avenue uses an A-type single-trumpet + T-type scheme. Expressway A crosses over Provincial Highway 102 and the toll station ramps, with the toll station located on the east side of Expressway A. The interchange of Expressway A and F-Avenue uses a "double-trumpet + leaf-type" interchange design, approximately 7.5 kilometers south of the existing G-Avenue interchange on Expressway A and approximately 9.8 kilometers north of the T-station on Expressway A. Furthermore, the H Interchange in XX City is the golden intersection of Expressway A and Expressway I, adopting an "interchange-type, fully directional" design concept, constructing a three-level three-dimensional traffic system. The main line is an eight-lane dual carriageway, and the ramps are two-lane single-direction ramps, with a design speed of 120 km / h. Examples are shown in Table 1 below. Table 1 Name Pole No. Direction Type XX City W Station Information Board K643+600 Up Single-screen R Station Information Board K648+100 Up Single-screen D East Road Station Information Board K653+100 Up Single-screen T Station Information Board K658+300 Up Single-screen Y District North Station Information Board K675+400 Up Single-screen Y District Station Information Board K678+100 Up Single-screen P Station Information Board K685+400 Up Single-screen XX City W Station Information Board K643+600 Down Single-screen R Station Information Board K648+100 Down Single-screen D East Road Station Information Board K653+100 Down Single-screen T Station Information Board K658+300 Down Single-screen Y District North Station Information Board K675+400 Down Single-screen Y District Station Information Board K678+100 Down Single-screen P Station Information Board K685+400 Down Single-screen Management information may include: 1. Targeted Approach: Information boards are only for disseminating travel-related information, including speed limits, road conditions, weather conditions, traffic control, and service reminders. Commercial advertisements and irrelevant content are prohibited. Information must be matched with real-time traffic conditions; for example, information about sudden accidents should clearly indicate the corresponding road segment ahead to guide vehicles to pass safely.

[0038] 2. Simplicity and Aesthetics Principle: Language Requirements: Text should be concise and easy to understand, with no typos. The number of characters displayed per screen should generally be around 12. If the content exceeds the capacity, it can be divided into multiple screens according to meaning, alternating between them at 2-5 second intervals, or a scrolling format can be used (no more than 20 characters). Layout and Font: Text should be centered, using boldface to improve readability; red is used for prohibitory information (e.g., no passage), yellow for warning information (e.g., heavy rain warning), and green for general notices (e.g., service area open). Important information can be repeated or flashed in special cases. Visual Design: Consider the physiological characteristics of drivers, and select a display scheme based on weather and time of day to ensure the information has strong visual impact (e.g., yellow for rainy days, high-contrast colors for nighttime).

[0039] 3. Priority Review Principle: Information may not be published or modified without prior review. Content must be proofread before publication to ensure accuracy. Road condition information is reviewed by the duty manager of the Operations Command Center, while non-road condition information is reviewed by the company office. Special instructions require confirmation from a higher-level department.

[0040] 4. Practicality and Effectiveness Principle: Information must have practical guiding significance, prioritizing driver and passenger safety, emergency response, and toll service notification. Content should be clear and specific; for example, accident information should include the location, affected lanes, and detour suggestions; construction information should specify the road section, construction period, and traffic control measures.

[0041] 5. Road Condition Priority Principle: When multiple pieces of information need to be published, they will be displayed in priority order: Category A (Highest Priority): Road condition information (traffic accidents, construction and maintenance, traffic control, station congestion, detour guidance, etc.). Category B: Weather warnings (heavy rain, heavy fog, snow, etc.), service reminders (service area status, charging station availability, etc.). Category C: Information during special periods such as holidays, promotional slogans (e.g., safe driving promotions). Category D: Driving safety tips (e.g., wear seat belts, prohibit fatigue driving, etc.). Category E: Other information.

[0042] 6. Timely Update Principle: Monitor road conditions in real time, and promptly update, modify, or delete outdated information to ensure its timeliness. Information on emergencies (such as accidents or traffic control) must be released immediately after the event and dynamically updated based on the progress of the response; information on construction, weather, etc., must specify the expected end time and be automatically withdrawn upon expiration.

[0043] The review rules can include: reasonableness, legality, compliance, etc.

[0044] For example, legality check (a veto item): Legal and regulatory compliance: √ Passed: Does not involve state secrets, false information, violent content, or other illegal information. × Rejected: Contains content prohibited by the Cybersecurity Law and the Road Traffic Safety Law, or involves privacy breaches.

[0045] Sensitive information screening.

[0046] Accuracy testing (core indicator); Basic Data Correctness: √ Pass: The road segment chainage is valid (e.g., "K100~K200" format is correct and falls within the jurisdiction of this road segment); the time / date is valid (e.g., "Construction until May 10, 2025" is not earlier than the current time); the values ​​are reasonable (e.g., speed limit ≤ 120km / h, visibility description matches real-time weather). × Problems: Incorrect chainage (e.g., "K2000" exceeds the limit), typos (e.g., "heavy rain" should be "torrential rain"), logical contradictions (e.g., "smooth traffic" and "congestion" coexist).

[0047] Information Completeness: √ Passed: Accident / Construction: Includes location, affected lanes, and response measures (e.g., "Truck overturned 100 meters ahead, blocking lane 2, slow down"); Weather / Control: Clearly states the road section, affected area, and specific instructions (e.g., "Heavy rain ahead, speed limit 60km / h within 10km"). × Problem: Missing key elements (e.g., "Accident ahead, proceed with caution" lacks location and lane information).

[0048] Compliance Check (Industry Standards): Format Compliance: √ Passed; Character Count Meets Requirements: Single screen ≤ 16 characters, scrolling screen ≤ 24 characters (e.g., "Construction ahead, left lane occupied until May 10th" displayed on 2 screens); Correct Font / Color: Use boldface, red (prohibition), yellow (warning), and green (hint) to match the information type (e.g., use red for traffic control information); No Special Symbols: Use only commas and periods, no incompatible symbols such as "→" or "!".

[0049] Priority Compliance: √ Passed: Sorted according to the "road condition priority principle" (e.g., accident information takes precedence over holiday slogans). × Issue: High-priority information (e.g., traffic accidents) is not released first, or low-priority information (e.g., promotional slogans) covers emergency notices.

[0050] Safety and Usability Testing: Risk Orientation: √ Pass: Instructions are clear and unambiguous (e.g., "Detour via G94 Exit" instead of "Detour"), without misleading content (e.g., "Caution Ahead" must clearly state the risk type). × Problem: Vague instructions (e.g., "Caution") or incorrect guidance (e.g., recommending a closed detour route).

[0051] Real-time matching: √ Pass: Weather / accident information is consistent with real-time data (e.g., when "heavy fog" is issued, the real-time weather is "heavy fog"); construction / control time is synchronized with the latest plan (e.g., the construction end time has not expired). × Problem: Information is outdated (e.g., "Construction ends on April 30, 2025", the current time is May 4).

[0052] Formatting and display compatibility: Information board display adaptation: √ Pass: Text is centered, without broken characters or misalignment, and conforms to the information board resolution (e.g., 16 characters per screen, with automatic line wrapping or scrolling). × Issue: Characters exceed the screen area (e.g., "Multiple vehicle collisions have occurred ahead due to heavy rain, please detour" is not split).

[0053] Step 102: For each information board to be displayed, perform the following processing steps: Step 1021: Generate the review prompt information corresponding to the above information board.

[0054] In some embodiments, the aforementioned executing entity can generate review prompt information corresponding to the aforementioned information board. The review prompt information includes: information board location, displayed information, publication time, and real-time traffic and weather information. Information board location indicates the current location of the information board. Display information can indicate the content displayed on the information board. Publication time can indicate the time the information was published. Real-time traffic conditions can indicate the current traffic conditions at the information board location. Weather information can indicate the weather information at the current location of the information board.

[0055] For example, the information board currently displays the following: Screen 1: "Road ahead is congested, please slow down" (green text, displayed for 20 seconds); Screen 2: "Speed ​​limit 130km / h, please do not exceed the speed limit" (yellow text, displayed for 20 seconds). The review notification message may be: 1. Proposed content to be released: First screen content: ["Road ahead is congested, please slow down"], font color: green, display time: 20 seconds; Second screen content: ["Speed ​​limit 130km / h, please do not exceed the speed limit"], font color: yellow, display time: 20 seconds; 2. Real-time data: Current time: [May 4, 2025, 14:00]; Location: [D East Road Station Upbound Information Board]; Real-time weather: [Sunny, visibility 1000 meters]; Real-time traffic conditions: [Road clear]; Special events: [None].

[0056] Step 1022: Perform compliance verification on the above audit prompt information to generate a compliance verification result.

[0057] In some embodiments, the aforementioned executing entity can perform compliance verification on the aforementioned review prompt information to generate a compliance verification result. For example, it can call an AI large-scale model through the Ollam interface to perform compliance detection. The AI ​​large-scale model can be a neural network model used to detect whether the review prompt information is compliant. For example, the AI ​​large-scale model can be a natural language processing (NLP) model or a computer vision (CV) model. Among them, the natural language processing (NLP) model can be a BERT / RoBERTa model. The computer vision (CV) model can include: CNN and ViT (Vision Transformer): to identify deepfake content.

[0058] In practice, the aforementioned implementing entities can verify the compliance of the above-mentioned audit prompts through the following steps: The first step is to retrieve the corresponding review prompt vector data from the aforementioned vector database. For example, based on the words included in the review prompt information, the corresponding vector data can be retrieved from the aforementioned vector database and used as the review prompt vector data.

[0059] The second step involves using the pre-trained information compliance detection model based on the aforementioned audit prompt vector data to generate compliance verification results. This information compliance detection model can be a pre-trained neural network model used to detect whether information is compliant. For example, it could be a natural language processing (NLP) model or a computer vision (CV) model. The compliance verification result can indicate whether the compliance verification passed or failed.

[0060] For example, the compliance verification result could be: the content review of the first screen fails, the real-time traffic conditions are smooth, and the published road congestion is unreasonable; the content review of the second screen fails, the speed limit for this road section is 120 km / h, and the published speed limit of 130 km / h is non-compliant.

[0061] Step 1023: In response to determining that the above compliance verification result indicates that the review has been passed, the above review prompt information is stored in the published information database.

[0062] In some embodiments, the aforementioned implementing entity may, in response to determining that the compliance verification result indicates that the audit has passed, store the aforementioned audit prompt information in the published information database.

[0063] Step 1024: According to the preset session key, encrypt the information to be delivered corresponding to the above information board to generate encrypted delivery information, and send the encrypted delivery information to the secure terminal of the above information board.

[0064] In some embodiments, the aforementioned execution entity can encrypt the information to be displayed on the information board according to a preset session key to generate encrypted information, and send the encrypted information to the secure terminal of the information board. The information to be displayed can represent information to be displayed on the information board. For example, the information to be displayed on the information board can be asymmetrically encrypted using a preset key and a digital certificate to negotiate the session key, thereby generating encrypted information.

[0065] Step 103: In response to the current time being the target time, obtain the information display list from the security terminal of the target intelligence board, and determine whether the above information display list is consistent with the corresponding published information playlist.

[0066] In some embodiments, the aforementioned executing entity may, in response to the current time being the target time, obtain an information display list from the secure terminal of the target intelligence board, and determine whether the information display list is consistent with the corresponding published information playlist. For example, the target time may refer to a pre-set time for content detection. The information display list may be a list of various information displayed on the target intelligence board since a compliance verification. That is, it can be determined whether the aforementioned information display list is the same as the corresponding published information playlist. The published information playlist may be a list of published information published to the target intelligence board stored in the publishing platform. The target intelligence board may refer to the intelligence board to be inspected.

[0067] Step 104: In response to the determination that the above information display list is inconsistent with the corresponding published information playlist, the target information board is locked.

[0068] In some embodiments, the aforementioned execution entity may lock the target information board in response to determining that the information display list is inconsistent with the corresponding published information playlist.

[0069] In practice, the aforementioned implementing entities can lock the target intelligence board using the following steps: The first step is to send a power-off command to the security terminal of the aforementioned target information board, thereby controlling the circuit breaker to cut off the power supply to the target information board. Information board power-off: The management system sends a power-off command to the security terminal, which then cuts off the power supply to the information board via the circuit breaker.

[0070] The second step is to send a black screen command to the controller of the aforementioned target information board to forcibly pause the display of content. Information board black screen: Send a black screen command to the information board controller to forcibly stop the display of content.

[0071] Simulation of information board display content monitoring function: (1) Send a message that can be approved through the management platform: "Trucks are prohibited from occupying the overtaking lane for a long time" and display it on the information board; (2) Modify the displayed content to "Trucks can occupy the overtaking lane for a long time" through the publishing software of another direct-connected information board controller; (3) The management platform obtains the current playlist from the information board controller through the secure terminal and compares it with the publishing record; (4) If the management platform discovers that the content displayed on the information board has been tampered with, it will immediately perform a power outage and issue an alarm; (5) The security terminal immediately disconnects the power to the information board to prevent the continued display of illegal content.

[0072] Further reference Figure 2 As an implementation of the methods shown in the above figures, this disclosure provides some embodiments of an information board content security review and detection device, which are similar to...

The compliance verification result indicates that the review has passed, and the review prompt information is stored in the published information database. Based on the preset session key, the information to be delivered corresponding to the information board is encrypted to generate encrypted delivery information, and the encrypted delivery information is sent to the secure terminal of the information board. The determining unit 203 is configured to, in response to the current time being the target time, obtain the information display list from the secure terminal of the target information board and determine whether the information display list is consistent with the corresponding published information playlist. The locking unit 204 is configured to, in response to determining that the information display list is inconsistent with the corresponding published information playlist, lock the target information board.
