[0040] To help those skilled in the art better understand this solution, the following will clearly describe the technical solutions in the embodiments of this solution in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of this solution, not all of it. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this solution.

[0041] Throughout the specification, claims, and accompanying figures of this solution, the term "including" and any variations thereof mean "including, but not limited to," and are intended to cover non-exclusive inclusions and are not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish between different objects, not to describe a specific order.

[0042] The following describes the implementation of the present disclosure in detail with reference to the accompanying drawings:

[0043] Figure 1 This is a schematic diagram of the structure of a highway monitoring device provided by an embodiment of the present disclosure. Figure 1 The highway monitoring device includes: a meteorological monitoring module, a network monitoring module, a control module, a road monitoring module, a switch module, a data transmission module, a data processing module and a sensor module.

[0044] The control module is connected to the weather monitoring module, network monitoring module, road monitoring module, switch module, and sensor module. The network monitoring module is configured to monitor network status information. The control module is configured to control the switch module's on / off state based on the network status information. The road monitoring module is configured to collect highway road video data.

[0045] The weather monitoring module is connected to the sensor module. The weather monitoring module is configured to collect weather data and control the working state of the sensor module based on the weather data. The sensor module is configured to collect road surface information.

[0046] The data processing module is connected to the data transmission module and the switch module respectively.

[0047] The data transmission module is connected to the switch module and is used to connect to an external monitoring terminal. The data transmission module is configured to transmit road video data and road surface information.

[0048] In this embodiment, the switch module includes a relay unit.

[0049] The first end of the relay unit is connected to the control module, the second end of the relay unit is connected to the data processing module, and the third end of the relay unit is connected to the data transmission module.

[0050] The network monitoring module monitors the network status information in real time. The network status information may include the connection stability and bandwidth of the network. The control module controls the switching status of the switch module according to the network status information. When the network condition is good, the control module generates corresponding control instructions to control the contacts of the relay unit to move to the third end of the relay unit, that is, to connect the data transmission module and disconnect the data processing module. The data transmission module works normally and transmits the collected road video data and road surface information to the external monitoring terminal. If the network fails or the bandwidth is insufficient, the control module controls the contacts of the relay unit to move to the second end of the relay unit, that is, to connect the data processing module and disconnect the data transmission module. At this time, the control module transmits the relevant road video data to the data processing module. After analysis and processing by the data processing module, the processed data is transmitted to the external monitoring terminal via the data transmission module.

[0051] The data processing module can process the image, extract image features and analyze them to obtain processed data. At this time, the amount of data is greatly reduced, which is conducive to improving data transmission efficiency.

[0052] In this embodiment, a weather monitoring module is connected to a sensor module. The weather monitoring module is configured to collect weather data, such as temperature, humidity, wind speed, and visibility. Based on the collected weather data, the weather monitoring module can determine the extent to which the current weather conditions affect the road surface, and thereby control the operating state of the sensor module. For example, in inclement weather such as rain or snow, the sensor module is activated to begin operation or a designated function of the sensor module is activated, such as increasing the frequency of collecting information such as road surface humidity, temperature, and ice formation. The sensor module can collect specific road surface information, such as temperature, humidity, road surface smoothness, and the presence of accumulated water, snow, or foreign objects, according to the instructions of the weather monitoring module.

[0053] In this embodiment, the road monitoring module uses cameras to collect video data from the highway, recording vehicle driving conditions and traffic conditions. This data is then transmitted to an external monitoring terminal via a data transmission module. The staff at the external monitoring terminal can use this data to understand the highway's operating status in real time, enabling them to take timely management and maintenance measures.

[0054] For example, consider a heavy snowstorm in winter. The weather monitoring module collects real-time meteorological data, such as a sudden drop in temperature, increased humidity, and reduced visibility, thereby identifying severe weather conditions. The weather monitoring module controls the sensor module to increase the frequency of collecting information on road surface temperature, humidity, and ice formation. The road monitoring module's camera continuously records road video data, showing that the road surface is gradually covered with snow, vehicles are slowing down, and the distance between them is increasing.

[0055] At this point, if the network monitoring module detects insufficient network bandwidth due to the heavy data transmission demand caused by inclement weather, the control module will control the relay unit in the switch module to connect the data processing module and disconnect the data transmission module. The data processing module compresses the road video data, removes redundant information, and analyzes and extracts key features such as areas with slow traffic and sections with heavy snow. The processed data is then transmitted to the external monitoring terminal via the data transmission module. Based on this information, staff promptly dispatch snowplows to the heavily snowed sections. At the same time, variable message signs are used to remind drivers to slow down and maintain safe distances, ensuring safe and smooth traffic on the highway in inclement weather. This enables efficient management and timely response based on real-time monitoring data.

[0056] From the above, it can be concluded that, on the one hand, this embodiment realizes accurate monitoring of the road conditions of the highway through the linkage between the meteorological monitoring module and the sensor module, so that the sensor module can intelligently adjust the working mode according to the real-time meteorological conditions, which not only ensures the accurate collection of data, but also reduces energy consumption and extends the service life of the equipment.

[0057] Furthermore, the collaboration between the network monitoring module and the control module ensures stable and efficient data transmission. Data transmission methods can be adjusted in real time based on network status, effectively avoiding network congestion and ensuring high-speed, stable transmission of road video data and road surface information. This improves data transmission efficiency and facilitates rapid response to traffic accidents or abnormal situations. The application of the data processing module significantly enhances the value of data utilization. By compressing, de-redundanting, and extracting features from road video data, not only does it reduce data volume but it also extracts key information, providing more accurate data support for highway management and maintenance.

[0058] In summary, this embodiment not only improves data transmission efficiency, but also enhances the safety monitoring and management capabilities of highways, providing strong support for smart transportation construction.

[0059] like Figure 2 As shown, in one embodiment of the present disclosure, the weather monitoring module includes:

[0060] Visibility monitor, rain sensor and wind speed and direction instrument.

[0061] Visibility monitors, rain sensors and wind speed and direction meters are all installed on the highway.

[0062] The visibility monitor, rain sensor and wind speed and direction meter are all connected to the control module.

[0063] In this embodiment, the visibility monitor measures light attenuation caused by atmospheric particles by emitting light and receiving scattered or reflected signals, thereby determining visibility conditions. A rain sensor, using a tipping bucket or other device, calculates rainfall based on the accumulated amount of rainwater received. An anemometer uses components such as a wind cup or vane, which rotate or oscillate in response to wind, converting the signals into electrical signals to determine wind speed and direction. These devices transmit the collected data in real time to a control module for subsequent processing and analysis.

[0064] For example, the visibility monitor can be installed in a location with a wide and unobstructed view that can represent the overall visibility conditions of the road section, such as a high pole on a highway, away from obstacles such as buildings and trees, at a height of about 5-10 meters.

[0065] Rain sensors can be installed in relatively open areas that can accurately receive rainwater, such as next to roadside guardrails or on special brackets, to avoid being affected by splashes from passing vehicles or rainwater blocked by other objects.

[0066] Anemometers can be installed at high places where there are no large buildings or mountains around to block the wind. They are usually installed at weather stations or communication towers along highways, at a height of more than 10 meters, to ensure that the speed and direction of natural wind can be accurately measured.

[0067] The visibility monitor utilizes a high-precision optical sensor and a stable transmitter-receiver with excellent anti-interference capabilities. The rain sensor features a corrosion-resistant, high-precision tipping bucket and a sensitive electrical signal triggering device. The wind speed and direction meter's cup and vane are constructed from lightweight, durable materials, while the angle sensor and wind speed sensor offer high accuracy and stability. These devices can be connected to the control module via shielded cables or wireless communication modules to ensure accurate and stable data transmission.

[0068] The weather monitoring module performs preliminary processing and analysis on the collected data. The results are then transmitted to the control module, which can make decisions based on preset thresholds and rules, such as initiating severe weather warnings. Simultaneously, weather data is transmitted in real time to relevant monitoring terminals for staff to monitor and analyze.

[0069] This embodiment improves the accuracy and timeliness of meteorological data, providing a scientific basis for highway safety management. Through precise measurement and data analysis, it can timely detect and warn of severe weather, effectively reducing the risk of traffic accidents. At the same time, real-time transmission of meteorological data also provides strong support for traffic management and scheduling, ensuring the smooth and safe operation of highways under complex weather conditions.

[0070] like Figure 2 As shown, in one embodiment of the present disclosure, the sensor module includes:

[0071] Temperature sensor and humidity sensor: The temperature sensor and humidity sensor are connected to the control module and the weather monitoring module respectively.

[0072] Temperature sensors and humidity sensors are both installed on the road surface of the highway.

[0073] In this embodiment, the temperature and humidity sensors can be installed on the highway pavement near the traffic lanes, for example, embedded in the pavement structure or mounted on a special bracket adjacent to the pavement. This ensures accurate sensing of the actual road surface temperature and humidity without excessive interference from vehicle airflow and other external factors. The temperature sensor should be a high-precision, stable thermistor or other suitable temperature detection element, and should be installed with waterproofing, moisture-proofing, and heat-insulating treatment. The humidity sensor uses a highly sensitive, fast-response capacitive sensor element and is equipped with a protective housing. The sensor is connected to the control module and weather monitoring module via a wired connection (e.g., a shielded cable) to ensure stable signal transmission.

[0074] This embodiment can reflect the temperature and humidity conditions of the road surface in real time, provide accurate data for the meteorological monitoring and control module, help to timely warn of safety hazards such as icy and slippery road surfaces, and provide strong support for highway safety management.

[0075] like Figure 2 As shown, in one embodiment of the present disclosure, the data processing module includes:

[0076] Image processor and data analysis unit.

[0077] The image processor is connected to the data analysis unit and the switch module respectively.

[0078] The image processor is configured to process the road video data to obtain road feature data. The data analysis unit is configured to analyze the road feature data.

[0079] In this embodiment, the image processor receives road video data from the road monitoring module and uses image processing algorithms such as edge detection and object recognition to extract characteristic information such as vehicles, pedestrians, and traffic signs on the road, converting this information into road feature data. The data analysis unit then performs in-depth analysis of this road feature data, such as statistics on traffic flow, speed distribution, and vehicle trajectories, to understand traffic conditions and potential problems.

[0080] The image processor may include a data input interface (receiving image data), a processing core (such as a CPU or GPU to perform image processing operations), a data storage unit (temporarily storing data during processing), and a data output interface (transmitting road feature data to a data analysis unit).

[0081] For example, during rush hour on a highway, the image processor receives video data from the road monitoring module via the data input interface. The image processor uses edge detection technology to distinguish road boundaries and vehicle outlines, and uses target recognition technology to identify vehicles, pedestrians, and other targets. This information is converted into road feature data and transmitted to the data analysis unit via the data output interface. The data analysis unit detects high traffic volume, concentrated speed distribution in lower speed ranges, and frequent lane changes in some vehicle trajectories. The analyzed data and road feature data are then transmitted to an external monitoring terminal via the data transmission module. Based on these analysis results, traffic management authorities can implement measures such as increasing temporary lane controls and reminding drivers to maintain safe distances to alleviate congestion and ensure traffic safety.

[0082] This embodiment can accurately extract and analyze key features in road video data in real time, providing traffic management departments with detailed traffic status analysis reports. Through in-depth analysis of traffic volume, speed distribution, and vehicle driving trajectories, it helps to promptly identify potential problems such as traffic congestion and illegal lane changes, facilitating the adoption of targeted management measures. In addition, after data processing, the data transmission volume is reduced and the data transmission speed is increased. The efficient data processing capability also enhances the response speed of the monitoring system, providing a strong guarantee for safe and smooth traffic on highways, and effectively improving road traffic efficiency and traffic management level.

[0083] like Figure 2 As shown, in one embodiment of the present disclosure, a highway monitoring device further includes:

[0084] Vehicle detection module.

[0085] The vehicle detection module is connected to the control module.

[0086] The vehicle detection module is configured to collect traffic flow data on the highway.

[0087] In this embodiment, the vehicle detection module can utilize electromagnetic induction to detect changes in induced current to determine vehicle passage and calculate traffic volume. Alternatively, microwave radar technology can be used to detect vehicle presence and speed based on frequency and phase changes in microwave signals reflected from vehicles, thereby calculating traffic volume.

[0088] For example, a vehicle detection module may include a sensor (such as a toroidal coil, microwave radar transceiver, or video camera), a signal processing unit (which amplifies, filters, and performs analog-to-digital conversion on the raw signals collected by the sensor), a data calculation unit (which calculates traffic flow data based on the processed signals), and a communication interface (for data transmission with the control module). The vehicle detection module can be installed on the main lanes of a highway, such as lanes near toll booths, mid-sections of important road sections, or at the junction of ramps and the main road. These locations can better represent the traffic flow conditions of the entire road section, facilitate installation and maintenance, and minimize disruption to normal traffic.

[0089] This embodiment can collect traffic flow data on highways in real time and accurately, providing important decision-making basis for traffic management departments; by accurately counting traffic flow, it helps to promptly detect abnormal situations such as traffic congestion and accidents, making it easier to quickly take countermeasures.

[0090] In one embodiment of the present disclosure, the vehicle detection module includes:

[0091] Multiple piezoelectric sensors.

[0092] Multiple piezoelectric sensors are installed under the road surface of the highway.

[0093] In this embodiment, piezoelectric sensors can be installed along the lanes of a highway, evenly spaced at regular intervals. For example, they can be located in the middle of each lane or near areas where wheels are likely to pass. Sensor density can be appropriately increased at key locations such as highway entrances and exits, accident-prone areas, curves, and ramps to more accurately detect vehicle entry, exit, and changes in driving status.

[0094] For example, choose piezoelectric sensors with high sensitivity and durability to ensure they can withstand repeated vehicle traffic and various harsh environmental conditions. When installing the sensors under the road surface, ensure they are waterproof, moisture-proof, and securely fixed to prevent damage from road deformation or vibration. Connect each piezoelectric sensor to the data acquisition device via cables to ensure stable signal transmission.

[0095] The vehicle detection module in this embodiment uses piezoelectric sensors to accurately detect vehicle dynamics and improve traffic monitoring accuracy. The sensor layout is flexible and key locations are encrypted to ensure comprehensive data.

[0096] like Figure 2 As shown, in one embodiment of the present disclosure, a highway monitoring device further includes: an alarm module.

[0097] The alarm module is connected to the control module.

[0098] In this embodiment, the alarm module receives command signals from the control module. When the control module detects an abnormal situation on the highway based on data from other modules (such as the weather monitoring module and vehicle detection module), such as low visibility due to inclement weather, congestion caused by excessive traffic volume, speeding, or an accident, it sends a corresponding control signal to the alarm module. Upon receiving the signal, the alarm module issues an alarm through its own audible and visual alarm devices, alerting relevant personnel and prompting them to take appropriate measures.

[0099] For example, the warning module can be installed in a conspicuous location along the highway, such as on a high roadside pole, at toll booths, service areas, and at tunnel entrances and exits. The warning module can use a high-brightness warning light, such as an LED light, with a strong flashing function to attract attention. The warning module can be equipped with a high-power speaker capable of producing a clear, loud, and adjustable alarm sound. The warning module should be housed in a sturdy enclosure that is waterproof, dustproof, and corrosion-resistant to withstand the harsh environment of highways.

[0100] The alarm module in this embodiment can respond to the control module's instructions in real time, and promptly remind drivers of abnormal highway conditions such as bad weather and traffic congestion through sound and light alarms, effectively enhancing emergency response capabilities, ensuring driving safety, reducing accident risks, and improving overall safety and practicality.

[0101] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
