Description

Technical Field

[0001] The present invention relates to the technical field of traffic safety warning devices, and specifically to a multi-power supply intelligent warning device and method for rural road traffic safety. Background Art

[0002] With the development of the rural economy, the scale of the rural road network has been continuously expanding. However, there is a mismatch between the scale of the rural road network and safety facilities. Rural road intersections are high-incidence areas of traffic accidents, and the safety situation is severe. These intersections usually belong to unsignalized intersections, where various types of motor vehicles, non-motor vehicles, pedestrians and other traffic flows converge, with numerous traffic conflict points and extremely high safety risks.

[0003] In the case of no traffic signal control, drivers are extremely likely to cause traffic accidents due to blocked vision or misjudgment. At the same time, non-motor vehicles and pedestrians are also prone to collisions due to non-compliance with traffic rules in these places. In addition, rural roads generally lack a sound power grid facility, making it difficult to ensure the daily operation of electronic devices, which brings serious bottlenecks to the use of various traffic safety facilities.

[0004] Existing traffic safety facilities are difficult to meet the special needs of rural road intersections. Either they have high energy consumption and high costs and cannot be widely applied in rural areas, or they have a single function and cannot comprehensively and effectively warn and respond to various traffic conditions. Therefore, there is an urgent need to develop a traffic safety facility for rural road intersections that has low energy consumption, low cost and is effective. Summary of the Invention

[0024] The warning device main body realizes wireless communication and mutual linkage of adjacent devices through the Lora wireless network, realizes remote communication and data upload through 4G remote communication, and realizes remote management of devices and parameter modification through the cloud platform.

[0025] With the above technical solution, by adopting the Lora wireless communication solution and setting up an edge computing gateway integrating 4G function and edge computing capability, this communication architecture not only meets the long-distance and low-power communication requirements in the rural road environment, but also can utilize the 4G network to achieve remote communication and data upload.

[0028] A method for using a rural road traffic safety intelligent warning device with multiple power supplies includes the following steps:

[0029] S1. Install the main body of the warning device at a suitable position at the rural road intersection, ensure its stability and do not obstruct traffic, and install an edge computing gateway integrating 4G function and edge computing capability according to the standard of setting one every 3 kilometers, and ensure that each main body of the warning device can communicate with the gateway normally;

[0030] S2. When the main body of the early warning device is in use, the chasing photovoltaic power generation structure is turned on, and according to the feedback of the light sensor, the horizontal position and tilt angle of the chasing photovoltaic power generation structure are adjusted to achieve the best lighting position, so that the chasing photovoltaic power generation structure converts solar energy into electrical energy to power the modules of the main body of the early warning device, and the excess electrical energy generated by the chasing photovoltaic power generation structure is stored in the power storage device. At night or when there is insufficient light, the power storage device powers the modules to ensure the stable operation of the main body of the early warning device. At the same time, the maintenance personnel periodically replace the power of the power storage device according to the plan;

[0031] S3. When the main body of the early warning device is in operation, the integrated video camera integrates the functions of the video acquisition module, the infrared sensor probe and the speed radar module, so that the integrated video camera can capture the traffic scene in real time, obtain the image information of vehicles and pedestrians, detect the movement of vehicles and pedestrians, and detect the speed and distance of vehicles, and display the vehicle speed on the speed display module;

[0032] S4. The rain and snow sensor monitors whether there is rain and snow, the air quality sensor detects the air quality, and the visibility sensor measures the current visibility. Each sensor and module transmits the collected traffic and environmental data to the edge computing gateway through the wireless transmission module and the Lora wireless network, performs preliminary processing using the edge computing capability, and then uploads it to the cloud platform through the 4G network;

[0033] S5. When making risk judgments and warnings, the warning device body uses intelligent algorithms to analyze the degree of risk based on the data collected by the monitoring module. When a dangerous situation is detected, such as vehicle speeding, driving in the wrong direction, or traffic congestion, the corresponding warning mechanism is triggered, and the LED display scrolls to display prompt messages such as "oncoming vehicle on the intersecting road" and "slow down", the red and blue light warning module flashes, and the voice broadcast module emits a warning voice;

[0034] S6. In a single intersection scenario, when a dangerous situation is detected, all devices at the intersection, including red and blue light warning modules, LED display screens, and voice broadcast modules, work together to issue warning information;

[0035] S7. In the continuous curve scene, multiple warning devices share information through the Lora wireless network. When a vehicle enters a curve, the warning device in front will issue a warning in advance, such as a voice reminder "curve ahead, slow down";

[0036] S8. In the case of multiple intersections, based on traffic flow and accident conditions, the over-the-horizon linkage of multiple intersection warning devices is realized. When an accident or traffic congestion occurs at a certain intersection, the warning devices at other related intersections will simultaneously issue warning information to guide vehicles to detour in advance.

[0037] S9. When an accident occurs, the warning device will release traffic control information through the LED display screen, such as "Accident ahead, please detour", etc. At the same time, it will cooperate with other warning devices upstream and downstream of the road section to display warnings to avoid secondary disasters. In addition, the accident information will be pushed to the traffic command center through 4G remote communication and data upload. The on-duty personnel of the traffic command center will make decisions based on the actual situation, carry out emergency disposal, and rescue the injured in time;

[0038] S10. Managers can remotely manage the main body of the warning device through the cloud platform, including modifying the display content of the LED display, adjusting the speed limit value, setting parameters such as voice broadcast content, etc. At the same time, the cloud platform continuously learns and summarizes traffic conflicts through AI models, combines expert review to determine effective warning plans, and saves them to the case library for subsequent calls.

[0039] (III) Beneficial effects

The device collects traffic information in real time through the monitoring module 9, analyzes the degree of danger using intelligent algorithms, and triggers corresponding linkage mechanisms according to the type and location of the detected dangerous situations; for example, at a single intersection, when vehicle speeding or traffic congestion is detected, all devices at this intersection, such as the red and blue light warning module 3, the LED display screen 5, the voice broadcast module 6, etc., work together to send warning messages; in the scenario of continuous curves, information sharing is carried out between multiple devices through the Lora wireless network, and when a vehicle enters a curve, the device in front sends a warning in advance; in the scenario of multiple intersections, over-the-horizon linkage of devices at multiple intersections is realized according to traffic flow and accident situations, and at the same time, the interval speed measurement function is realized through the radar-vision integrated machine 12, and targeted reminders are made according to vehicle speed and traffic conditions; when the traffic flow is low or there is no traffic activity, the device enters the intelligent sleep state to reduce energy consumption.

Each sensor transmits the collected environmental information to the inside of the device for integration. The information collected by each monitoring sensor is preliminarily processed on the terminal device, such as performing simple analysis and feature extraction on the image data, and calibration and filtering operations on the sensor data to improve the accuracy and usability of the data. The preliminarily processed data is transmitted to the edge computing gateway set every 3 kilometers through the Lora wireless network. The Lora wireless communication has the characteristics of low power consumption and long distance, and can stably transmit the data of each terminal device to the edge computing gateway in the rural road environment. After receiving the data, the edge computing gateway uses its edge computing ability to further process and analyze the data, perform fusion processing on the data of multiple sensors, extract key information, such as identifying traffic congestion points, judging abnormal vehicle speeds, analyzing traffic conflicts, etc., and perform preliminary classification and sorting on the data. The data processed by the edge computing is uploaded to the cloud platform through the 4G module. The cloud platform has powerful computing and storage capabilities, can receive a large amount of traffic and environmental data, and perform in-depth analysis and mining on these data;

[0064] The cloud platform uses big data algorithms and intelligent models to comprehensively analyze the uploaded data. By comparing and analyzing historical data and real-time data, it judges the traffic conditions and the degree of danger, predicts the change trend of traffic flow, identifies potential traffic safety risks, and generates decision-making instructions: According to the analysis results, the cloud platform generates corresponding decision-making instructions. For example, when traffic congestion is detected, an instruction to adjust the warning parameters is generated; when a traffic accident occurs, an instruction to release traffic control information is generated, etc.;

[0065] Managers can log in to the cloud platform through the command center, PC terminal or mobile terminal to view traffic information and device status, and perform remote management and parameter modification. For example, according to the actual traffic demand, adjust the warning threshold, modify the display content, etc. The cloud platform sends the decision-making instructions to the edge computing gateway through the 4G network, and the edge computing gateway then conveys the instructions to each terminal device through the Lora wireless network;

[0066] When the monitoring module 9 of a single intersection detects speeding, wrong-way driving or other illegal behaviors or traffic congestion, the red and blue light warning module 3 of the intersection starts flashing to issue a visual warning; the LED display screen 5 scrolls to display relevant warning information, such as "vehicle speeding, please slow down" and "congestion ahead, please detour", etc.; the voice broadcast module 6 simultaneously issues voice reminders to inform passing vehicles and pedestrians to pay attention to traffic safety; in the continuous curve scene, multiple devices share information through the Lora wireless network; when a vehicle enters the curve, the device at the entrance detects the vehicle information and transmits the information to the devices at the subsequent curves through the Lora network, and these devices send warnings in advance Warnings are issued, such as flashing of the red and blue light warning module 3, display of information such as "curve ahead, slow down" on the LED display screen 5, and voice reminders from the voice broadcast module 6, to guide vehicles to pass the curve safely; when a traffic accident or serious traffic congestion or other major events occur at a certain intersection, the cloud platform instructs the devices of multiple related intersections to perform beyond-visual-range linkage according to the scope and severity of the event, and the red and blue light warning modules 3, LED display screen 5, and voice broadcast module 6 of each intersection work together to display unified warning information, such as "accident ahead, please detour", to guide vehicles to change their driving routes in advance, to avoid further aggravation of traffic congestion and the occurrence of secondary disasters;

[0067] Through the above complete workflow, the multi-channel energy-supply rural road level crossing traffic safety intelligent warning device realizes the comprehensive collection, efficient processing, intelligent decision-making and coordinated linkage between equipment of traffic and environmental information, effectively improving the traffic safety level of rural road level crossings.

[0068] like Figure 7 As shown, the present invention also provides a method for using a multi-channel energy supply rural road traffic safety intelligent warning device, comprising the following steps:

[0069] S1. Install the warning device body 1 at a suitable location at the rural road level crossing, ensure that it is stable and does not hinder traffic, and install an edge computing gateway with integrated 4G functions and edge computing capabilities according to the standard of setting one every 3 kilometers, and ensure that each warning device body 1 can communicate normally with the gateway;

[0070] S2. When the main body 1 of the early warning device is in use, the chasing photovoltaic power generation structure 2 is turned on, and according to the feedback of the light sensor, the horizontal position and the tilt angle of the chasing photovoltaic power generation structure 2 are adjusted to achieve the best lighting position, so that the chasing photovoltaic power generation structure 2 converts solar energy into electrical energy to power each module of the main body 1 of the early warning device, and the excess electrical energy generated by the chasing photovoltaic power generation structure 2 is stored in the power storage device 8. At night or when the light is insufficient, the power storage device 8 powers each module to ensure the stable operation of the main body 1 of the early warning device. At the same time, the maintenance personnel periodically replace the power of the power storage device 8 according to the plan;

[0071] S3. When the main body 1 of the early warning device is in operation, the integrated machine 12 for visual inspection integrates the functions of the video acquisition module, the infrared sensor probe and the speed radar module, so that the integrated machine 12 for visual inspection can capture the traffic scene in real time, obtain the image information of vehicles and pedestrians, detect the movement of vehicles and pedestrians, and detect the speed and distance of the vehicle, and display the vehicle speed on the speed display module 4;

[0072] S4. The rain and snow sensor 14 monitors whether there is rain and snow, the air quality sensor 15 detects the air quality, and the visibility sensor 16 measures the current visibility. Each sensor and module transmits the collected traffic and environmental data to the edge computing gateway through the wireless transmission module 7 via the Lora wireless network, performs preliminary processing using the edge computing capability, and then uploads it to the cloud platform through the 4G network;

[0073] S5. When making risk judgment and warning, the warning device body 1 uses intelligent algorithms to analyze the risk level based on the data collected by the monitoring module 9. When a dangerous situation is detected, such as speeding, wrong-way driving, traffic congestion, etc., the corresponding warning mechanism is triggered, and the LED display screen 5 scrolls and displays prompt information such as "oncoming vehicle on the intersecting road" and "slow down", the red and blue light warning module 3 flashes, and the voice broadcast module 6 issues a warning voice;

[0074] S6. In a single intersection scenario, when a dangerous situation is detected, all devices at the intersection, including the red and blue light warning module 3, the LED display 5, the voice broadcast module 6, etc., work together to issue a warning message;

[0075] S7. In the continuous curve scene, multiple warning device bodies 1 share information through the Lora wireless network. When a vehicle enters a curve, the warning device body 1 in front issues a warning in advance, such as a voice reminder "curve ahead, slow down";

[0076] S8. In the multi-intersection scenario, according to the traffic flow and accident situation, the multi-intersection warning device body 1 is linked beyond visual range. When an accident or traffic congestion occurs at a certain intersection, the warning device body 1 of other related intersections simultaneously issues warning information to guide vehicles to detour in advance;

[0077] S9. When an accident occurs, the warning device body 1 releases traffic control information through the LED display screen 5, such as "Accident ahead, please detour", etc. At the same time, it cooperates with other warning device bodies 1 upstream and downstream of the road section to display warnings to avoid secondary disasters. The accident information is pushed to the traffic command center through 4G remote communication and data upload. The on-duty personnel of the traffic command center make decisions based on the actual situation, carry out emergency disposal, and rescue the injured in time;

[0078] S10. Managers achieve remote management of the main body 1 of the warning device through the cloud platform, including modifying the display content of the LED display screen 5, adjusting the speed limit value, setting parameters such as voice broadcast content, etc. At the same time, the cloud platform continuously learns and summarizes traffic conflicts through the AI model, determines an effective warning plan in combination with expert review, and saves it to the case library for subsequent call.
