Description

Technical Field

[0001] The present invention relates to the technical field of lighting monitoring, and particularly to a method, device, equipment and storage medium for warning the operation of guardrail lights. Background Art

[0002] The setting of road low-level lighting has significant safety benefits; the low-level lighting method provides necessary visibility for night driving, ensures the illuminance and uniformity of the road surface, and at the same time avoids the glare interference to the driver's line of sight, ensuring the safe passage of vehicles; the construction of low-level lighting technology is simple. Compared with traditional lamp post lighting, the light source position is lower, improving the utilization rate of light; in particular, the setting of road guardrail lights plays a key role in safety. These lamps can clearly demarcate the safe and dangerous areas, effectively prevent pedestrians or vehicles from accidentally crossing the boundary, and reduce the risk of traffic accidents; at night or under insufficient light conditions, the soft light of the guardrail lights provides clear guidance for pedestrians and vehicles, avoiding getting lost and entering unsafe areas.

[0003] However, the current function of guardrail lights is limited to providing lighting, and a natural disaster warning mechanism has not been integrated; in actual operation, this limitation may lead to several problems; firstly, the safety risk may increase because when a natural disaster occurs, the guardrail lights without a warning function cannot issue a danger warning to the public in time, thus increasing the possibility of accidents; secondly, the efficiency of emergency response may be affected because the guardrail lights cannot provide necessary alarms at the initial stage of the disaster, thus delaying the start of rescue operations; finally, the transmission of emergency information may not be sufficient because the role of guardrail lights as an important part of urban infrastructure in information dissemination has not been fully utilized.

[0004] Therefore, the prior art still needs further improvement and enhancement. Summary of the Invention

[0021] For ease of understanding, the specific process of the embodiments of the present invention will be described below. Please refer to Figure 1 , an embodiment of the method for early warning of the operation of guardrail lights in the embodiments of the present invention includes:

[0022] 101. Obtain road environment information and generate an initial layout plan based on the road environment information;

[0023] In this embodiment, by systematically obtaining road environment information, the actual conditions of the road can be comprehensively and accurately understood; the road environment information provides a solid and scientific basis for the layout of guardrail lights, ensuring the rationality and effectiveness of the initial layout plan, thereby avoiding layout mistakes caused by incomplete information.

[0024] 102. Perform standard verification on the initial layout plan. If the initial layout plan passes the standard verification, output the guardrail light layout plan;

[0025] In this embodiment, strict standard verification is performed on the initial layout plan to evaluate the feasibility of actual construction; by performing standard verification, unreasonable points in the initial layout plan can be discovered and corrected in time, avoiding waste of resources and rework phenomena in subsequent construction, significantly improving work efficiency and project quality, and ensuring the smooth progress of the guardrail light layout project.

[0026] 103. After the guardrail lights are arranged and the guardrail light communication network is constructed based on the guardrail light layout plan, obtain the guardrail light operation information;

[0027] In this embodiment, after the arrangement of the guardrail lights and the construction of the guardrail light communication network are completed based on the initial arrangement plan, the system continuously obtains the working information of the guardrail lights; the communication module of the guardrail lights integrates 4G and Beidou dual-mode positioning technologies, ensuring accurate position information can be obtained in various environments; in addition, the communication module also reserves an RS485 expansion interface, providing convenience for possible future function expansion; further, each guardrail light realizes real-time feedback of the working state through the RDM protocol, enabling managers to monitor the operation of each guardrail light instantaneously; through real-time monitoring, the reliability and safety of road lighting can be ensured, potential problems can be discovered and processed in a timely manner, and the safety of road users can be guaranteed.

[0028] 104. Preprocess the working information of the guardrail lights, and judge whether it is necessary to trigger an early warning based on the preprocessed working information;

[0029] 105. If it is necessary to trigger an early warning, confirm the early warning level, and generate an early warning instruction based on the confirmed early warning level;

[0030] In this embodiment, the refined preprocessing of the working information of the guardrail lights can screen out the most critical information, providing an accurate and reliable basis for early warning judgment; if the system judges that it is necessary to trigger an early warning, it further confirms the early warning level and generates corresponding early warning instructions according to the confirmed early warning level; this process not only improves the timeliness and accuracy of the early warning, but also can take corresponding countermeasures according to different levels of early warnings to ensure that road anomalies can be quickly and effectively handled.

[0031] This application discloses a method for early warning of the working status of guardrail lights. By reasonably designing the guardrail light arrangement plan, the survival rate of guardrail lights on the road section in the event of sudden natural disasters can be significantly improved. Specifically, through optimization of the layout, the survival rate of guardrail lights can be greatly increased from the original 63% to 97%; in addition, during the normal operation of the guardrail lights, their status is monitored in real time, and an early warning mechanism is triggered according to the collected working information; during natural disasters, this early warning response time is greatly shortened, from the original 45 seconds to only 22 seconds, enabling relevant departments and the public to receive alarms faster in case of emergencies, so as to take necessary preventive measures and reduce the losses and impacts that may be brought by disasters.

[0032] In this embodiment, the obtaining of road environment information and generating an initial arrangement plan based on the road environment information includes:

[0033] 201. Obtain road environment information, where the road environment information includes road grade, road width, section information, and climate information;

[0034] In this embodiment, road grades are clearly classified into expressways, urban expressways, and mountain roads; expressways specifically refer to those roads that connect cities or regions and are designed for high-speed driving, usually with multiple lanes and restricted access characteristics; urban expressways refer to dedicated roads within or around cities that aim to provide rapid traffic flow, and these roads may include overpasses, tunnels, and dedicated traffic signal systems; mountain roads specifically refer to roads that pass through mountainous or hilly areas, which may contain more curves, steeper slopes, and more complex road conditions.

[0035] In this embodiment, section information, as a key element in this embodiment, includes an important classification of section types; section types are further subdivided into disaster-prone sections and ordinary sections. Disaster-prone sections refer to those sections where natural disasters such as landslides, mudslides, floods, or avalanches have frequently occurred in history. These sections require special monitoring and maintenance to ensure driving safety; while ordinary sections refer to those sections that are relatively stable and without frequent natural disasters.

[0036] In this embodiment, climate information is defined as regional climate type information, which is summarized based on historical climate data; climate types are divided into three main categories: heavy rain areas, dry areas, and normal areas; heavy rain areas refer to those areas that are frequently affected by heavy rainfall, and these areas may cause disasters such as floods or landslides; dry areas refer to those areas with extremely low precipitation and dry climates, and these areas may face problems such as droughts and sandstorms; normal areas refer to those areas with relatively stable climates and without extreme climate characteristics.

[0037] 202. Confirm the installation height and road correction coefficient based on the road grade, confirm the safety redundancy coefficient based on the section information, and confirm the climate correction coefficient based on the climate information;

[0038] In this embodiment, for expressways, the recommended installation height is set between 0.9 and 1.2 meters, and the road correction coefficient is adjusted within the range of 0.8 to 1.2 according to specific circumstances; for urban expressways, the recommended installation height is generally 0.8 to 1.0 meters, and the road correction coefficient is also flexibly adjusted within the range of 0.8 to 1.2 according to actual needs; for mountain roads, due to complex terrain, the recommended installation height will be relatively low, generally between 0.6 and 0.8 meters, and the road correction coefficient may be appropriately increased, usually adjusted within the range of 1.2 to 1.5 to adapt to the special road conditions in the mountains.

[0039] In this embodiment, for sections where disasters occur frequently, the safety redundancy coefficient is set to 0.8; while for ordinary sections, the safety redundancy coefficient is set to 1.0.

[0040] In this embodiment, for areas with frequent heavy rain, the climate correction coefficient is set to 0.7; for arid areas, the climate correction coefficient is set to 1.2; while for conventional areas, the climate correction coefficient is set to 1.0.

[0041] 203. Calculate the initial layout spacing based on the road width, layout height, road correction coefficient, safety redundancy coefficient, and climate correction coefficient, and generate an initial layout plan based on the initial layout spacing;

[0042] In this embodiment, the initial layout spacing S is calculated based on the following formula:

[0043]

[0044] where H is the layout height, W is the road width, K is the road correction coefficient corresponding to the road grade, C env is the climate correction coefficient, and L safe is the safety redundancy coefficient.

[0045] In this embodiment, by obtaining road environment information, including road grade, road width, section information, and climate information, the layout height, safety redundancy coefficient, and climate correction coefficient of road lighting facilities can be accurately determined, so as to calculate the optimal initial layout spacing and generate an initial layout plan accordingly, ensuring that road lighting is both efficient and safe, making the generated initial layout plan adaptable to different road conditions and climate impacts, and improving the lighting effect of road guardrail lights and driving safety.

[0046] In this embodiment, the road environment information further includes the road length and road orientation; the generating an initial layout plan based on the initial layout spacing includes:

[0047] 301. Confirm the reference spacing range based on the road grade, and determine whether the generated initial layout spacing falls within the reference spacing range;

[0048] In this embodiment, for the design standard of expressways, the determined reference spacing range is 15 to 20 meters. This spacing setting comprehensively considers the safety distance, visibility, and dynamic characteristics of vehicles under high-speed driving conditions; for urban expressways, the recommended reference spacing range is 12 to 18 meters, which is designed to adapt to the high density of urban traffic and frequent vehicle starts and stops; as for mountain roads, due to their special terrain and many curves, the recommended reference spacing range is 8 to 12 meters to ensure that vehicles can drive safely and smoothly on the winding roads.

[0049] 302. If the initial layout spacing falls within the reference spacing range, generate a basic layout plan based on the road length, road orientation, and initial layout spacing;

[0050] In this embodiment, first, the length and orientation of the road are determined. These two factors are crucial for determining the overall layout of the layout plan. The length and orientation of the road directly affect the layout density and distribution pattern of the guardrail lights, ensuring the matching of the lighting effect with the road characteristics. Secondly, the initial layout spacing is considered. This is a key parameter affecting the layout density and uniformity. The selection of the initial layout spacing needs to comprehensively consider factors such as the width of the road, traffic flow, lighting standards, and safety requirements. After confirming that the initial layout spacing is within the range of the reference spacing, we use this spacing as an important basis for generating the plan. Finally, the MicroStation road design tool is used to evenly distribute the guardrail lights on the road guardrail to generate the basic layout plan. MicroStation, as a powerful road design software, provides accurate modeling and visualization functions, enabling designers to intuitively adjust and optimize the layout of the guardrail lights. Through software simulation, it can be ensured that the layout position of each guardrail light meets the design requirements, while considering the feasibility of actual construction and the convenience of maintenance.

[0051] 303. Optimize the basic layout plan based on the road grade and section information to obtain the initial layout plan.

[0052] In this embodiment, the rationality of the initial layout spacing is verified through the reference spacing range set based on the road grade, and accordingly, a standard-compliant basic layout plan is generated. Furthermore, the plan is optimized by considering information such as the road length and orientation to ensure that the finally obtained initial layout plan not only meets the road grade requirements but also adapts to the specific section conditions, thereby improving the scientificity and practicality of the road design.

[0053] In this embodiment, the optimization of the basic layout plan based on the road grade and section information to obtain the initial layout plan includes:

[0054] 401. The section information further includes low-risk section information and high-risk section information. The low-risk section information includes the number of low-risk sections, the length of each low-risk section, and the location of each low-risk section. The high-risk section information includes the number of high-risk sections, the length of each high-risk section, and the location of each high-risk section.

[0055] 402. Confirm the spacing encryption ratio corresponding to the low-risk section information based on the road grade, and generate the low-risk adjustment plan for each low-risk section based on the length of the low-risk section, the spacing encryption ratio, and the initial layout spacing.

[0056] In this embodiment, for the low-risk sections of expressways, the spacing needs to be encrypted, and the encryption ratio is set at 40%. This measure aims to further enhance the road safety performance and reduce the potential risk of traffic accidents. For urban expressways, corresponding spacing encryption measures are also taken. The spacing encryption ratio for low-risk sections is 30%. This strategy aims to improve the smoothness of urban traffic while ensuring driving safety. As for mountain roads, given their special geographical environment and complex road conditions, the spacing encryption ratio for low-risk sections has been specially increased to 50% to cope with the high-risk characteristics of mountain roads and ensure the safety of drivers and passengers.

[0057] 403. Obtain the preset maximum density, and generate the high-risk adjustment plans for each high-risk section based on the length, maximum density, and initial layout spacing of the high-risk sections;

[0058] In this embodiment, for the sections identified as high-risk, the layout strategy of the maximum density is adopted by default. Specifically, the facility spacing of the guardrail lights is set to half of the standard spacing value, that is, 50%. This strategy can significantly increase the frequency of monitoring and warning, thereby effectively reducing the probability of accidents. At the same time, it can also provide more timely safety information for drivers to ensure driving safety.

[0059] 404. Optimize the basic layout plan based on the low-risk section information and its corresponding low-risk adjustment plan, as well as the high-risk section information and its corresponding adjustment plan, to obtain the initial layout plan.

[0060] In this embodiment, the detailed classification of section information helps to more accurately identify and handle sections with different risk levels. By formulating targeted adjustment plans for low-risk sections and high-risk sections respectively, the road safety and traffic efficiency can be effectively improved. The consideration of the spacing encryption ratio for low-risk sections and the maximum density for high-risk sections ensures that appropriate lighting, monitoring, and management measures are taken on different sections, thereby optimizing the overall road layout plan, reducing the accident risk, and improving driving safety.

[0061] In this embodiment, perform a standard check on the initial layout plan. If the initial layout plan passes the standard check, output the guardrail light layout plan, including:

[0062] 501. Based on the initial layout plan, use the DIALux tool to generate a simulated illuminance cloud map;

[0063] In this embodiment, by introducing the DIALux tool to generate a simulated illuminance cloud map, it can intuitively reflect the lighting effect after the guardrail lights are arranged in a high-precision and visual manner. It not only provides a solid data basis for the subsequent plan evaluation but also enables designers to more clearly understand the lighting distribution, thus making more scientific decisions.

[0064] 502. Determine whether the initial layout plan meets the preset illumination difference requirement and the preset shadow area ratio requirement based on the simulated illumination cloud map;

[0065] In this embodiment, based on the generated simulated illumination cloud map, the initial layout plan is comprehensively and carefully checked to ensure that the plan can strictly meet the preset illumination difference requirements and shadow area ratio requirements. This not only improves the rationality and effectiveness of the guardrail lamp layout, but also greatly reduces the safety hazards caused by insufficient lighting or excessive shadows, thereby ensuring the safety and comfort of users.

[0066] In this embodiment, the preset illumination difference requirement is: within a continuous range of 50 meters, the change in lighting intensity should be less than 20%; at the same time, the preset shadow area ratio requirement is that the shadow area ratio shall not exceed 15%.

[0067] 503. If the simulated illumination cloud map satisfies both the preset illumination difference requirement and the preset shadow area ratio requirement, it indicates that the initial arrangement plan passes the standard verification, and the initial arrangement plan is output as the guardrail lamp arrangement plan;

[0068] In this embodiment, if the simulated illumination cloud map has been verified, the initial layout plan can be directly output as the final guardrail light layout plan, which not only avoids the tedious plan adjustment and optimization process, significantly improves work efficiency, but also ensures the accuracy and reliability of the plan, making the entire design process more efficient and smooth.

[0069] In this embodiment, the preprocessing of the guardrail light working information and judging whether to trigger an early warning based on the preprocessed working information include:

[0070] 601. The guardrail light working information includes real-time inclination information, real-time vibration intensity information and real-time deformation rate;

[0071] In this embodiment, the acquisition of real-time inclination information is achieved through a three-axis inclinometer, which can accurately measure and feedback the inclination angles of the equipment or structure in three vertical axes, thereby providing key data for the stability and balance of the system; at the same time, in order to monitor and evaluate the real-time vibration intensity, a miniature accelerometer is used as a sensor, which can detect tiny vibration changes and feed back these vibration data to the control system in real time to ensure timely response and take corresponding measures to reduce the impact of vibration; in addition, in order to monitor the deformation of the guardrail during use, a strain monitoring unit is equipped to monitor and feedback the deformation rate in real time, that is, the deformation amount of the structure or material per unit time.

[0072] 602. Perform data cleaning processing, data smoothing processing, and feature extraction processing on the guardrail light working information in sequence to obtain pre-processing working information;

[0073] In this embodiment, data cleaning is first performed to remove invalid, duplicate, or abnormal data, ensuring the quality and accuracy of the data; then, the moving average method is used for data smoothing to reduce noise and fluctuations in the data, improving the smoothness and continuity of the data; then, feature extraction is performed to extract key feature information from the cleaned and smoothed data.

[0074] 603. Obtain preset weight information, where the preset weight information includes a preset inclination weight, a preset vibration weight, and a preset deformation weight;

[0075] In this embodiment, the preset inclination weight is 40%, the preset vibration weight is 30%, and the preset deformation weight is 30%; the weight information is obtained based on a large number of experiments and data analyses, and can scientifically reflect the influence degree of each parameter on the health status of the guardrail lights; based on the preset weight information, data fusion processing is performed on the preprocessing work information, and the weights of each parameter are integrated to calculate an abnormal comprehensive score; this score comprehensively reflects the current working state and potential risks of the guardrail lights.

[0076] 604. Perform data fusion processing on the preprocessing work information based on the preset weight information to obtain an abnormal comprehensive score;

[0077] In this embodiment, the comprehensive score = real-time inclination information * inclination weight + real-time vibration intensity information * vibration weight + real-time deformation rate * deformation weight.

[0078] 605. Obtain a preset warning threshold, and determine whether to trigger a warning based on the abnormal comprehensive score and the preset warning threshold;

[0079] In this embodiment, the preset warning threshold is 0.7; based on the judgment of the abnormal comprehensive score and the preset warning threshold, if the comprehensive score exceeds the warning threshold, the system will immediately trigger a warning mechanism to ensure that problems can be quickly handled, effectively prevent damage or safety accidents caused by abnormal states of the guardrail lights, ensure road traffic safety, and can also achieve effective early warning of sudden natural disasters.

[0080] In this embodiment, if it is necessary to trigger a warning, the warning level is confirmed, and a warning instruction is generated based on the confirmed warning level, including:

[0081] 701. When the abnormal comprehensive score ≥ the preset warning threshold, confirm the warning level according to the abnormal comprehensive score, and the warning level includes a deceleration warning and an interruption warning;

[0082] In this embodiment, if the comprehensive anomaly score reaches or exceeds 0.7, the warning mechanism is triggered; subsequently, according to the specific value of the comprehensive anomaly score, the warning levels are divided into two categories: deceleration warning and interruption warning; the specific division criteria are formulated according to actual business requirements. For example, the state with a score between 0.7 and 0.9 is defined as a deceleration warning, and the state with a score exceeding 0.9 is defined as an interruption warning; through this classification method, it is possible to orderly respond to anomalies of different degrees, which can not only improve the safety awareness of road users but also effectively prevent traffic accidents from occurring.

[0083] 702. When the warning level is a deceleration warning, a deceleration warning instruction is generated. The deceleration warning instruction includes controlling the interval flashing of guardrail lights, starting the sound deceleration alarm device, and controlling the display board to display speed limit warning information.

[0084] In this embodiment, if the alarm level is a deceleration warning, the intermittent flashing mode of the guardrail lights should be started at a frequency of once per second, and the brightness should be maintained at 2000 candela per square meter; at the same time, control the sound deceleration alarm device, such as a broadcasting device, to play a prompt sound of "Danger ahead, slow down", and the volume should be controlled at 70 decibels; further, control the information display board to display a warning message of "Road anomaly, speed limit 20 km / h".

[0085] 703. When the warning level is an interruption warning, an interruption warning instruction is generated. The interruption warning instruction includes controlling the flashing of guardrail lights, starting the audible and visual interruption alarm device, and controlling the display board to display interruption alarm information.
