Description

Technical Field

[0001] The present invention relates to the technical field of intelligent safety early warning and positioning monitoring, and in particular to an urban road guardrail system supporting intelligent safety early warning and positioning services. Background Art

[0002] In recent years, with the continuous advancement of urbanization and the improvement of transportation infrastructure construction, the guardrail industry has developed rapidly. As an important part of urban road traffic, guardrails not only bear the important responsibility of isolating traffic and protecting pedestrians, but also play an important role in improving the overall quality of the road environment. On the one hand, the regulations on building safety and traffic safety are becoming increasingly stringent, and higher standards are put forward for the design, installation and use of facilities such as guardrails. On the other hand, with the growing demand for intelligent and modern transportation in society, the functions of traditional guardrails have gradually become single and difficult to meet the increasingly complex road environment needs.

[0003] Existing urban road guardrails are mainly passive isolation, and their functions are limited to preventing vehicles from crossing the line and separating motor vehicle and non-motor vehicle lanes. However, this type of traditional guardrail has many shortcomings in practical applications. For example, when the guardrail is overturned or displaced due to external force, it cannot be sensed and reported in time, which may lead to further expansion of traffic accidents. At the same time, for urban managers, the inspection and maintenance work efficiency is low, and it is impossible to quickly and accurately grasp the operating status of the guardrail. In addition, with the development of autonomous driving technology, road infrastructure needs to have a higher level of intelligence in order to provide accurate road position signals for the navigation of new energy vehicles. However, traditional guardrails lack intelligent sensing and positioning functions and cannot adapt to the needs of these emerging technologies.

[0004] Urban road safety has also become particularly important with the development of society. The increasing traffic of vehicles and pedestrians has put forward higher requirements for road safety facilities. Especially in complex urban traffic environments, traditional guardrails cannot provide intelligent warning and positioning functions, which makes it difficult for management departments to respond in time when emergencies occur. In addition, in recent years, the demand for positioning and search and rescue functions has gradually increased. For example, how to use infrastructure to help find lost children, the elderly or pets is an urgent problem to be solved in urban intelligent management.

[0005] In order to solve the above problems, the present invention proposes an urban road guardrail system that supports intelligent safety warning and positioning services. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides an urban road guardrail system that supports intelligent safety warning and positioning services, which solves the problems that traditional guardrails cannot monitor the dumping status in real time, accurately locate the dumping position, and lack intelligent warning and positioning services.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: an urban road guardrail system supporting intelligent safety warning and positioning services, comprising: A road guardrail assembly module is installed on the road and used for road isolation.

The dumping warning module is installed on the top of the column and is used to regularly monitor whether the guardrail is tilted and generate an alarm signal in time. The road-end column data transmission base station is installed in the end column of each section of urban road guardrail. It is used to complete the data reception reported by the dumping warning module and transmit it to the server through the network. The server is used to receive the data reported by the road-end column data transmission base station and transmit the information to the urban road maintenance management department and the traffic management department in real time.

[0008] Preferably, a flower box is installed on the top of each column.

[0009] Preferably, the dumping warning module includes: Tilt sensor, used to detect the posture parameters of the guardrail; A Bluetooth signal sending device, used for sending posture parameter data and position signals; Unique location code, used to identify the location information of each column; Button battery, used to power the tipping warning module; The power detection module is used to monitor the battery power status and send an alarm signal when the battery is low; The environmental monitoring module is used to collect environmental data of the area where the guardrail is located, including temperature, humidity, wind speed and air quality, and package the environmental data and guardrail posture parameters into a Bluetooth broadcast package and send it to the roadside column data transmission base station (7). When the environmental data exceeds the set safety threshold, the system generates active warning information and pushes it to the relevant management department.

[0010] Preferably, the roadside column data transmission base station comprises: A data receiver, used to receive the Bluetooth data packet sent by the dumping warning module; A network communication module, used to transmit data to a server via a wired or wireless network; Data filtering strategy module, used to receive only Bluetooth signals with specific device names and perform data analysis; A power module, used to provide continuous power supply to the data transmission base station; Cameras to monitor vehicle and pedestrian behavior around the guardrail through real-time video capture and analysis; Behavior analysis module, which is used to identify abnormal activities near the guardrail, including vehicles hitting the guardrail, pedestrians crossing the line or vandalism, and upload image data and analysis results to the server; The vibration monitoring module is used to monitor the vibration frequency and intensity of the guardrail caused by vehicle impact, wind or other external forces in real time, and upload the vibration data to the server to assist in health assessment.

[0011] Preferably, the tilt sensor comprises: A power supply module is used to supply power to the three-axis acceleration sensor and the main control module; The three-axis acceleration sensor is used to support acceleration detection in the three directions of X / Y / Z and transmit the acceleration values ​​in the three directions to the main control module; Bluetooth 5.0 master control module, used to receive data from the tilt sensor, calculate the tilt information, and package the data into Bluetooth broadcast packets for wireless transmission; Bluetooth RF matching circuit, used to optimize the sending and receiving performance of Bluetooth signals; The GPS module is used to regularly report the precise location of the guardrail when it is moved or transported.

[0012] Preferably, the server comprises: A data processing module for identifying the guardrail collapse location and generating warning information; Information storage module, used to store guardrail posture parameter data, location information, alarm records and equipment operation status information uploaded from the road end column data transmission base station The alarm push module is used to send early warning information to the urban road maintenance management department and the traffic management department.

[0013] Preferably, the surface of the guardrail sheet is sprayed with a luminous coating, which is made of a photoluminescent material and is used to provide a visual warning function in a low-light environment.

[0014] Preferably, a self-cleaning coating is provided on the surface of the luminous coating, which is prepared by using super hydrophobic material or self-cleaning nano coating technology.

[0015] The present invention provides an urban road guardrail system that supports intelligent safety warning and positioning services. It has the following beneficial effects: 1. The present invention adopts a technical solution that combines a dumping warning module with a Bluetooth signal sending device, which realizes the function of real-time monitoring of the dumping status of the guardrail and timely issuing an alarm. Compared with the existing technology that simply relies on manual inspections, it greatly improves the automation level of guardrail status monitoring and solves the problems of low inspection efficiency and long response time.

[0016] 2. The present invention realizes dual detection of the inclination state and precise position of the guardrail by introducing the design of independent position coding and three-axis acceleration sensor. Compared with the solution in the prior art that fails to integrate the tipping detection and position information, it makes up for the problem of insufficient positioning accuracy and provides more accurate road boundary information for autonomous driving vehicles.

[0017] 3. The present invention achieves the dual effects of external force monitoring and damage assessment of the guardrail by combining the vibration monitoring module and the health assessment module. Compared with the existing method of relying solely on the tipping sensor, the present invention solves the problem of limited external force monitoring range in complex environments. At the same time, it can actively assess the fatigue state of the guardrail, significantly improving the system's forward-looking maintenance capabilities.

[0018] 4. The present invention generates a guardrail damage status report and maintenance recommendations through a health assessment module, and adopts an analysis method based on vibration data and historical records to achieve a quantitative assessment of guardrail damage and a prediction of service life. Compared with traditional maintenance methods that rely on manual inspections, the present invention can dynamically plan maintenance time and scope, reduce maintenance costs, and improve the long-term stability of guardrail facilities.

[0019] 5. The present invention realizes multi-factor real-time analysis of the guardrail status under complex external force conditions through the linkage between the vibration monitoring module and the environmental monitoring module. Compared with the prior art method in which the monitoring range is limited to a single tilt angle, the present invention can effectively distinguish the different impacts of external forces such as vehicle collisions and strong winds on the guardrail, solving the technical bottleneck of the high false alarm rate of traditional methods, and at the same time improving the system's adaptability to extreme weather.

[0020] 6. The technical solution of spraying luminous and self-cleaning coatings on the surface of the guardrail sheet of the present invention provides the dual effects of enhanced visibility at night and self-cleaning performance, which is in sharp contrast to the technology of traditional guardrail surfaces that are easily contaminated and have poor recognition at night. It effectively extends the service life of the guardrail and significantly reduces maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please see attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides an urban road guardrail system supporting intelligent safety warning and positioning services, including: A road guardrail assembly module 6 is installed on the road and used for road isolation. The road guardrail assembly module 6 includes a column 1, a guardrail sheet 2 and a dumping warning module 5. Both sides of the guardrail sheet 2 are respectively installed on two adjacent columns 1 through a guardrail column mounting seat 4. The dumping warning module 5 is installed on the top of the column 1, which is used to regularly monitor whether the guardrail is tilted and generate an alarm signal in time; The road-end column data transmission base station 7 is installed in the end column 1 of each section of the urban road guardrail, and is used to complete the reception of data reported by the dumping warning module 5 and transmit it to the server through the network. The server is used to receive the data reported by the road-end column data transmission base station 7 and transmit the information to the urban road maintenance management department and the traffic management department in real time.

[0025] The surface of the guardrail piece 2 is sprayed with a luminous coating, which is made of a photoluminescent material and is used to provide a visual warning function in a low-light environment.

[0026] A self-cleaning coating is arranged on the surface of the luminous coating, which is prepared by using super hydrophobic material or self-cleaning nano coating technology.

[0027] A flower box 3 is installed on the top of each column 1.

[0028] Specifically, the road guardrail system of the present invention is based on the road guardrail combination module 6, and through the close cooperation of the dumping warning module 5, the data transmission base station and the server, it realizes the real-time monitoring and abnormal alarm functions of the guardrail state, and has the ability of positioning and multi-functional expansion. The road guardrail combination module 6 is installed on the urban road, has an isolation function, and realizes the extended application far beyond the traditional guardrail through the intelligent module.

[0029] The road guardrail assembly module 6 includes a column 1 and a guardrail sheet 2, which are firmly connected through the guardrail column 1 mounting seat to ensure structural stability. The surface of the guardrail sheet 2 is sprayed with a luminous coating, which absorbs sunlight or artificial light energy during the day and releases light energy at night. Even in low-light environments, the guardrail outline can be clearly displayed, providing a safe visual reminder for drivers and pedestrians. At the same time, the application of the self-cleaning coating enables the guardrail surface to effectively resist the adhesion of dirt, moisture and dust, and automatically cleans under rain or water flushing, reducing the frequency of manual cleaning and the daily maintenance cost of the guardrail.

[0030] A tipping warning module 5 is installed on the top of each column 1. The tipping warning module 5 is a key monitoring unit of the system, which has a built-in three-axis acceleration sensor. The sensor can collect acceleration data of the guardrail in three directions in real time and calculate the inclination angle of the guardrail. When the guardrail tilts abnormally and exceeds the preset threshold, the module immediately determines that it is in a tipping state and triggers an alarm. In order to facilitate rapid positioning, each tipping warning module 5 is equipped with a unique location code. The code is preset in the map within the system and corresponds to the actual geographical location one by one, so that the location information included in the alarm signal can be directly used to locate the tipping location.

[0031] The dumping warning module 5 broadcasts alarm information via Bluetooth signals. The broadcast package contains data such as the tilt angle, position code, and module power status. This information is captured by the roadside column data transmission base station 7 installed at the end of the guardrail section. The base station receives the Bluetooth broadcast package by active scanning. The internal filtering strategy module ensures that only signals that meet the specified format and device name are processed, avoiding data interference and redundancy. After the base station parses the broadcast package, it uploads the dumping information to the server through the network.

[0032] After receiving the data, the server first analyzes the specific dumping location and status information of the guardrail through the data processing module. According to the data content, the server generates targeted early warning information and pushes it to the urban road maintenance management department and traffic management department in real time. In this way, the relevant departments can quickly dispatch maintenance personnel to the site to repair the guardrail, reducing the potential for accidents. At the same time, the server stores historical alarm records, guardrail status data and other information to facilitate subsequent data statistics and analysis.

[0033] The operation of the system is not limited to dumping monitoring, but also has positioning and rescue functions. The Bluetooth signal sending device of the dumping warning module 5 supports pairing with specific Bluetooth receiving devices (such as devices installed on the elderly, pets or vehicles). After the base station captures these signals, it transmits them to the server in combination with the location information. The server calculates the target location based on the signal strength and location, and notifies the nursing home or rescue agency of the results to achieve accurate positioning and rapid search and rescue. In addition, the dumping warning module 5 can be equipped with an optional GPS module. When the guardrail is displaced or transported, the module regularly uploads GPS positioning data to ensure dynamic monitoring of the guardrail position.

[0034] Through the above technical scheme, the present invention achieves the effects of intelligent monitoring, accurate alarm and multi-functional expansion that traditional guardrails cannot achieve, and significantly improves the safety and intelligence level of urban roads.

[0035] Please see attached Figure 5 and attached Figure 6 , the dumping warning module 5 includes: Tilt sensor, used to detect the posture parameters of the guardrail; A Bluetooth signal sending device, used for sending posture parameter data and position signals; A unique position code, used to identify the position information of each column 1; Button battery, used to power the tipping warning module 5; The power detection module is used to monitor the battery power status and send an alarm signal when the battery is low; The environmental monitoring module is used to collect environmental data of the area where the guardrail is located, including temperature, humidity, wind speed and air quality, and package the environmental data together with the guardrail posture parameters into a Bluetooth broadcast package and send it to the road end column data transmission base station 7. When the environmental data exceeds the set safety threshold, the system generates active warning information and pushes it to the relevant management department.

[0036] Specifically, the dumping warning module 5 is the core component of the present invention, and its functions are realized by the tilt sensor, the Bluetooth signal sending device, the environment monitoring module and other submodules. This module can not only monitor the dumping state of the guardrail in real time, but also collect the surrounding environment data and conduct intelligent analysis in combination with external factors, providing more reliable alarm and warning functions.

[0037] The tilt sensor is one of the core components of the tipping warning module 5, which is used to monitor the tilt angle of the guardrail. It calculates the posture of the guardrail in space by sensing the acceleration changes of the guardrail in the three directions of X, Y, and Z. When the guardrail tilt angle is detected to exceed the set safety threshold (such as 20°), the system determines that the guardrail may have a tipping risk.

[0038] As an extended functional component of the collapse warning module 5, the environmental monitoring module is used to collect real-time environmental data such as temperature, humidity, wind speed and air quality in the area where the guardrail is located. Changes in these environmental parameters may directly affect the judgment of the collapse of the guardrail. For example: Combination of wind speed and tilt monitoring: When the tilt sensor detects an abnormal change in angle, the environmental monitoring module will simultaneously detect whether the wind speed has reached the limit value (such as 20m / s). If the wind speed is abnormal and the tilt angle exceeds the threshold, the system determines that the main reason for the guardrail toppling may be strong wind.

[0039] Combining air quality with regional analysis: Air quality data can help identify environmental conditions in accident areas. For example, there may be risks of vehicle speeding or abnormal operation in severely polluted areas, providing data support for accident analysis.

[0040] The collaborative work of the two solves the problem of high false alarm rates in traditional systems due to external factors (such as wind or humidity), ensuring the accuracy and reliability of the alarm.

[0041] The data collection of the environmental monitoring module relies on the built-in multifunctional sensor array, which can independently complete the real-time monitoring of the external environment. The specific process is as follows: The monitoring data is stored in the module in the form of digital signals and synchronized with the attitude parameter data of the tilt sensor; The data is packaged into a Bluetooth broadcast packet and transmitted to the roadside column data transmission base station 7 at a fixed time through the Bluetooth signal sending device; The data packet adopts a layered coding method, which includes the unique position code of the guardrail, the tilt angle information, and the parameters such as temperature, humidity, wind speed, and air quality generated by the environmental monitoring module; After the data transmission is completed, the base station is responsible for further forwarding it to the server for subsequent processing.

[0042] This data transmission mechanism can not only efficiently integrate the multi-dimensional information of the guardrail, but also ensure the stability and integrity of data transmission, and is particularly suitable for operation in complex urban environments.

[0043] The environmental monitoring module will trigger active warning signals under preset conditions. For example: Strong wind warning: If the wind speed exceeds 25m / s (typhoon-level wind), the module will actively trigger the warning signal even if the tilt angle does not reach 20°. The system will combine the environment and guardrail status data to remind the management department to take protective measures in advance.

[0044] Comprehensive risk analysis: When the environmental monitoring module detects multiple parameter abnormalities (such as high humidity + strong wind + abnormal tilt), the system will generate a comprehensive risk report and push it to the city management department to help it respond quickly.

[0045] This early warning function avoids the limitation of traditional guardrail monitoring systems that can only alarm based on a single tilt parameter, and improves the adaptability and intelligence level of the system.

[0046] The dumping warning module 5 and the environmental monitoring module are designed with full consideration of power consumption requirements and environmental adaptability: Power consumption optimization: The module adopts intermittent acquisition and active sleep strategy, activating the sensor only when it needs to broadcast or detect key parameters. This design enables the module to run continuously for more than three years on a button battery.

[0047] Environmental adaptability: The module adopts a fully enclosed waterproof and dustproof shell, and all internal electronic components are specially treated to ensure stable operation under extremely high temperature, low temperature and high humidity conditions.

[0048] In addition, the system is equipped with a power detection module that can monitor the battery power in real time. When the power is low, the module sends a low-battery alarm signal via Bluetooth broadcast to remind managers to replace the battery in time to avoid the system from being unable to operate due to power outages.

[0049] After the environmental data and guardrail status data generated by the module are uploaded to the server, it can support a variety of application scenarios: Historical data analysis: The server will store all historical environmental parameters and guardrail status change records for subsequent safety assessment and trend analysis. For example, historical wind speed data in a specific area can help optimize the guardrail structure design.

[0050] Regional warning: The server combines the data from the environmental monitoring module to generate regional guardrail safety warnings in advance, such as pushing risk warnings before typhoons, heavy rains and other weather conditions occur.

[0051] Smart city application expansion: The collected environmental data can also provide real-time air quality information to environmental protection departments and provide auxiliary decision support for intelligent transportation systems.

[0052] This data management method greatly enhances the comprehensive value of the guardrail monitoring system, making it not only limited to traffic facility monitoring, but also able to provide more data support for urban governance.

[0053] Please see attached Figure 7 , the road end column data transmission base station 7 includes: A data receiver, used to receive the Bluetooth data packet sent by the dumping warning module 5; A network communication module, used to transmit data to a server via a wired or wireless network; Data filtering strategy module, used to receive only Bluetooth signals with specific device names and perform data analysis; A power module, used to provide continuous power supply to the data transmission base station; Cameras to monitor vehicle and pedestrian behavior around the guardrail through real-time video capture and analysis; Behavior analysis module, which is used to identify abnormal activities near the guardrail, including vehicles hitting the guardrail, pedestrians crossing the line or vandalism, and upload image data and analysis results to the server; The vibration monitoring module is used to monitor the vibration frequency and intensity of the guardrail caused by vehicle impact, wind or other external forces in real time, and upload the vibration data to the server to assist in health assessment.

[0054] Specifically, in this embodiment, the roadside column data transmission base station 7 continuously captures the Bluetooth broadcast data from the dumping warning module 5 through the built-in data receiver. The data receiver adopts a low-power operation mode and is equipped with a high-sensitivity Bluetooth receiving device, which can quickly capture the broadcast signal in a complex signal environment to ensure the reliable reception of key information such as guardrail inclination, position coding, battery status and environmental monitoring data. When the guardrail tilts or triggers the warning module, the receiver will capture the broadcast data in the first time to ensure timeliness.

[0055] In this embodiment, the received data is filtered by the data filtering strategy module. The module only processes the legitimate data from the dumping warning module 5 according to the preset device name and data format rules, and filters out the interference signals of the surrounding Bluetooth devices. This filtering strategy is implemented by combining hardware and software to ensure the accuracy of data analysis and the efficiency of system operation. The filtered Bluetooth data is parsed into structured information, including the inclination angle of the guardrail, position code, environmental parameters and battery power status. The parsed data provides a clear basis for subsequent upload and analysis.

[0056] In this embodiment, the network communication module built into the base station is responsible for uploading the parsed guardrail status data to the server. The communication module supports multiple transmission methods, including wired communication and wireless communication (such as 4G, 5G networks). In the core areas of the city or locations with good signal coverage, the module gives priority to using wired methods for stable transmission, and in remote areas or when network coverage is insufficient, it switches to wireless mode to ensure transmission capabilities. The communication module supports breakpoint resume function. When the network connection is interrupted, the module temporarily stores the unuploaded data in the local storage unit, and automatically resends it after the connection is restored to ensure data integrity.

[0057] In this embodiment, the power module provides continuous power support for each functional module of the base station, and adopts a dual power supply mode of the municipal power grid and a high-capacity lithium battery. When the municipal power supply is cut off, the module can seamlessly switch to battery power to ensure that the equipment can run continuously for several hours. The power module is equipped with a power detection unit that can monitor the remaining battery power in real time. When insufficient power is detected, the module will issue a low-battery alarm through Bluetooth broadcasting or network transmission to remind maintenance personnel to replace the battery in time. The module shell adopts a waterproof and dustproof design, and the internal electronic components have been specially treated to resist erosion in harsh environments such as high temperature, low temperature, and humidity.

[0058] In this embodiment, the base station integrates a high-definition camera for dynamic monitoring of the surrounding environment of the guardrail. The camera is equipped with a high-resolution lens, a wide viewing angle and dynamic focus function, and can accurately capture the details of the target area when the guardrail is abnormal. Through the built-in dynamic exposure adjustment function, the camera can provide clear images in complex lighting environments (such as strong direct sunlight during the day or low light at night), and improve nighttime monitoring capabilities through infrared fill light technology.

[0059] The video stream collected by the camera is transmitted to the behavior analysis module for real-time processing. In this embodiment, the behavior analysis module is based on an image recognition algorithm and can accurately identify abnormal behaviors around the guardrail, including vehicles hitting the guardrail, pedestrians crossing the line, or vandalism. The module marks the analyzed abnormal events as independent records and uploads the relevant images and the geographical location information of the guardrail to the server for the traffic management department to respond quickly.

[0060] In this embodiment, the vibration monitoring module uses a high-precision acceleration sensor to monitor the vibration amplitude, frequency and duration of the guardrail under the action of external forces in real time. The module can identify multiple sources of vibration, including vehicle impact, strong wind and construction disturbance, and classify and filter vibration events through intelligent algorithms to reduce the false alarm rate. The vibration data is uploaded to the server synchronously with the guardrail position code and tilt status information, providing reliable data support for the health status assessment of the guardrail.

[0061] The server calculates the damage degree and service life of the guardrail based on the vibration monitoring data and historical vibration records, combined with the health assessment model. In this embodiment, the real-time data of the vibration monitoring module can directly participate in the health assessment and early warning functions, generate maintenance suggestions before the guardrail reaches the fatigue limit, and intervene in potential risks in advance.

[0062] In this embodiment, each module in the base station works together to form a complete guardrail monitoring process. The data receiver captures the broadcast signal of the dump warning module 5, the filtering strategy module filters and analyzes the data, the camera and behavior analysis module monitors the dynamic environment around the guardrail, and the vibration monitoring module provides the guardrail physical status data. All information is uploaded to the server through the network communication module. The server generates a guardrail status report based on the comprehensive data, providing multi-dimensional data support for guardrail health maintenance, traffic safety management and accident analysis.

[0063] Please see attached Figure 4 , the tilt sensor includes: A power supply module is used to supply power to the three-axis acceleration sensor and the main control module; The three-axis acceleration sensor is used to support acceleration detection in the three directions of X / Y / Z and transmit the acceleration values ​​in the three directions to the main control module; Bluetooth 5.0 master control module, used to receive data from the tilt sensor, calculate the tilt information, and package the data into Bluetooth broadcast packets for wireless transmission; Bluetooth RF matching circuit, used to optimize the sending and receiving performance of Bluetooth signals; The GPS module is used to regularly report the precise location of the guardrail when it is moved or transported.

[0064] Specifically, the three-axis acceleration sensor detects the acceleration changes of the guardrail in the X, Y, and Z directions in real time. The tilt angle is calculated by the algorithm in the sensor and used to determine whether the guardrail is in an abnormal state. The precise collection of acceleration data can quickly capture the occurrence of tilt, ensuring that the problem can be identified in the initial state to avoid further expansion of the potential for tipping.

[0065] The method for calculating the tilt angle of the three-axis acceleration sensor can be referred to as follows: The dual-axis acceleration sensor can ensure the detection of the tilt angle on the XY plane, thereby detecting the motion state of the object. In addition to being able to calculate the tilt angles on the XY plane, YZ plane, and XZ plane separately like the dual-axis acceleration sensor, the triaxial acceleration sensor can also calculate the angle between each axis and the reference position.

[0066] Introducing the concept of reference position, the reference position is generally set to the position where the gravity component on the z-axis is 1 and there is no gravity component on the XY axis. At this time, the angles of θ, Ψ, and Φ are 0. By calculating the three angles of θ, Ψ, and Φ, the motion state of the object can be known.

[0067] The Bluetooth 5.0 main control module receives the acceleration data transmitted by the three-axis acceleration sensor and completes the task of calculating the inclination angle. The inclination angle is integrated with the device's unique position code, power status and other information, and the main control module packages this data into a broadcast data packet. Through Bluetooth signal transmission, the guardrail status information can be quickly transmitted to the data transmission base station for further processing. During the calculation and packaging process, the low power consumption characteristics of Bluetooth 5.0 technology reduce overall power consumption and improve data processing efficiency.

[0068] The Bluetooth RF matching circuit optimizes the transmission performance of Bluetooth signals, allowing the broadcast signal to maintain stability and a large coverage range in complex urban environments. The signal interference and attenuation problems are effectively solved, and the integrity of the data is guaranteed at the signal receiving end. Through frequency matching and transmission power adjustment, this design adapts to the communication needs of different distances and environments.

[0069] When the guardrail is moved or transported, the GPS module realizes real-time location tracking. By periodically reporting positioning data, the location information of the guardrail is always updated. The broadcast positioning information can be transmitted to the base station through the Bluetooth network to form a dynamic monitoring closed loop. The GPS module adopts a timed reporting design to reduce the frequency of unnecessary data transmission and save energy consumption.

[0070] Please see attached Figure 8 , the server includes: A data processing module for identifying the guardrail collapse location and generating warning information; Information storage module, used to store guardrail posture parameter data, location information, alarm records and equipment operation status information uploaded from the road end column data transmission base station 7 The alarm push module is used to send early warning information to the urban road maintenance management department and the traffic management department.

[0071] Specifically, the server is used to process and manage the data uploaded by the roadside column data transmission base station 7, and send the generated warning information to the relevant departments in a timely manner to ensure that guardrail abnormalities can be quickly discovered and handled. Through its internal functional modules, the server realizes the functions of data analysis, storage and alarm push, forming a complete system processing flow.

[0072] The data received by the server is first parsed by the data processing module. The data uploaded by the guardrail includes posture parameters, tilt angle, location information, and equipment status. The data processing module combines the unique location code of each guardrail to associate the specific tilt state with the actual geographical location. When the tilt angle exceeds the set safety threshold, the module immediately determines that the guardrail is in an abnormal state and generates detailed early warning information. The early warning information includes the dumping position of the guardrail, the tilt angle, and the operating status of the equipment. After processing, these data can intuitively present the location of the guardrail abnormality and the possible scope of impact, providing a clear basis for subsequent response.

[0073] The information storage module organizes and stores the guardrail status data uploaded from the base station, including tilt angle, location information, alarm records, and equipment operating status. Through structured storage, all historical records and operating data can be quickly queried and analyzed. For guardrail areas where alarms often occur, the stored data can provide a basis for in-depth analysis to help identify the root cause of the problem, such as construction interference or environmental impacts on certain sections of the road. In addition, the storage content of the equipment operating status can also provide guidance for regular maintenance, such as battery power consumption trends or changes in communication stability. These data provide a reliable foundation for the long-term management and optimization of the guardrail system.

[0074] When the warning information is generated, the alarm push module transmits the information to the urban road maintenance management department and the traffic management department in various ways. The push content includes the specific location of the guardrail, the tilting angle and the possible safety risks, and the precise location of the guardrail on the road is clearly displayed in combination with the map system. Through SMS, email or dedicated interface, the alarm information can reach the relevant personnel in the shortest time, ensuring that the maintenance work can be started quickly. The flexibility of the push method makes the system suitable for different management modes and application scenarios.

[0075] The overall operation process of the server realizes efficient conversion from data reception to warning push. Real-time data processing enables the tilt state to be quickly identified, while long-term data storage provides rich data support for subsequent analysis. Through the warning push function, relevant departments can obtain information about guardrail abnormalities in the first place, ensuring that the safety function of the guardrail is maintained and restored in a timely manner.

[0076] Working principle: The operation process of the urban road guardrail system of the present invention starts with the guardrail status monitoring. The dumping warning module 5 installed on the top of the guardrail column 1 collects the acceleration data of the guardrail in the three directions of X, Y, and Z in real time through the built-in three-axis acceleration sensor, and calculates the tilt angle. When the tilt angle of the guardrail exceeds the set threshold, the system determines that the guardrail is in an abnormal state. At this time, the Bluetooth 5.0 main control module packages the tilt angle information and the unique position code of the guardrail and the power status and other data into a Bluetooth broadcast data packet, and broadcasts it through a Bluetooth signal sending device. At the same time, the environmental monitoring module in the dumping warning module 5 collects environmental data such as temperature, humidity, wind speed and air quality in the area where the guardrail is located in real time. The system packages the tilt angle, environmental data, the unique position code of the guardrail and the power status and other data into a Bluetooth broadcast data packet, and broadcasts it through a Bluetooth signal sending device.

[0077] The broadcast signal is received by the data transmission base station 7 installed on the roadside column at the head of the guardrail section. The receiving module in the base station scans the surrounding Bluetooth signals and uses the filtering strategy module to filter out the broadcast packets that meet the set conditions. After the base station parses the inclination information, location code and power status in the broadcast data packet, it transmits the parsed data to the remote server through its network communication module.

[0078] After receiving all the data from the base station, the server locates the specific guardrail section where the abnormality occurs in combination with the unique position code of the guardrail, and conducts a comprehensive analysis of the tilt angle, vibration data, and environmental parameters. For example, when an abnormal tilt angle is detected and the wind speed reaches the set critical value, the server determines that the guardrail may have collapsed due to strong winds. If the vibration data shows abnormal amplitude and frequency, the system may determine that the guardrail has been hit or subjected to other external forces. Based on these comprehensive analyses, the server generates early warning information and pushes it to the urban road maintenance management department and the traffic management department, prompting them to take appropriate disposal measures. At the same time, the server stores the received tilt data, vibration data, environmental monitoring data, and alarm records for subsequent data analysis and maintenance decisions.

[0079] The camera in the data transmission base station 7 of the roadside column collects dynamic images around the guardrail through real-time video, and the behavior analysis module analyzes abnormal behaviors around the guardrail through image recognition algorithms. When abnormal behaviors such as vehicles hitting guardrails, pedestrians crossing the line or man-made damage are detected, the behavior analysis module extracts relevant event data and uploads the guardrail position and related images to the server. This information is used for accident analysis and rapid response, providing auxiliary decision support for traffic management departments and maintenance departments.

[0080] The surface of the guardrail sheet 2 is sprayed with a luminous coating, which absorbs energy from natural light or artificial light during the day and continues to emit light at night, providing vehicles and pedestrians with a clear visual warning effect on the road. The self-cleaning coating outside the luminous coating achieves an anti-fouling effect through super-hydrophobic or nano self-cleaning technology. The surface of the guardrail can be kept clean after being washed by rainwater, reducing the frequency of daily maintenance.

[0081] In addition, the dumping warning module 5 also supports Bluetooth positioning function. The module's Bluetooth signal sending device can broadcast signals regularly and pair with Bluetooth receiving devices worn by the elderly, pets or vehicles. After the roadside column data transmission base station 7 captures these signals, it uploads the location information to the server. The server calculates the positioning information based on the signal strength and notifies the relevant departments, such as nursing homes or rescue centers, of the location of the lost individual to complete the rapid positioning and tracking of the target.

[0082] When the guardrail is displaced or transported, the optional GPS module of the dump warning module 5 will regularly report the precise location information of the guardrail. The location information is sent to the base station via Bluetooth and then transmitted to the server to ensure that the change of the guardrail position can be monitored and recorded in real time.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
