Description

Technical Field

[0001] This invention relates to the field of road safety supervision technology, specifically to a monitoring device, system, and detection method for traffic guardrail collapse. Background Technology

[0002] Road traffic barriers are installed on road shoulders, traffic dividers, and sidewalk curbs. They are a type of road traffic safety isolation facility, mainly used to separate two-way motor vehicles, motor vehicles from non-motor vehicles, and pedestrians from vehicles.

[0003] As standard road traffic safety barriers, the supervision of the barriers themselves is particularly important. However, existing road traffic barriers on the market are all non-intelligent facilities, making it impossible to build a digital online monitoring system based on them; moreover, the barriers are relatively lightweight and are mainly assembled using a ground-mounted base. When strong winds, traffic accidents, or other unexpected collisions occur, the barriers may collapse, affecting the quality of safe road traffic operation and threatening the lives of drivers, passengers, and pedestrians.

[0004] The existing guardrails are non-intelligent, and their monitoring mainly relies on proactive accident reporting and manual inspections. Manual maintenance and inspections are inherently slow; secondly, when uncontrollable situations such as hit-and-run accidents or natural collapses (due to factors other than human intervention, such as strong winds or vibrations) occur, it's impossible to ensure immediate restoration of traffic flow, leading to road congestion and secondary traffic hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a monitoring device, system, and detection method for traffic barrier collapse failure, so as to solve the problems mentioned in the background art.

When the stop block is open, its bottom surface is parallel to the bottom surface of the fixing plate, and when the stop block is closed, its bottom surface is parallel to the side surface of the engaging groove.

[0020] Preferably, the side of the engaging groove is provided with a storage groove, and the bottom of the stop block is equipped with a rotating shaft, the two ends of which are rotatably mounted on the storage groove.

[0021] Preferably, when the stop block is closed, there is a gap between it and the top of the storage slot, and the lower parts of both ends of the card block have card slots that are adapted to the stop block.

[0022] Preferably, the middle part of the card block and the corresponding part of the mounting plate are provided with screw holes, and the fixing plate and the mounting plate are disassembled and assembled by bolts and screw holes.

[0023] Preferably, the fixing plate has a groove for receiving bolt heads.

[0026] Preferably, the inner bottom surface of each mounting port is provided with a mounting through hole.

[0027] Preferably, the delineator body is also provided with a QR code area and an LED light.

[0028] Preferably, the main chip is also connected to an LED light to display the power status of the control circuit, and the outline marker body is provided with an IoT card slot for inserting an IoT card (the IoT card can be omitted when the built-in eSIM module is selected); the outline marker body is provided with a product label for recording the basic information of the device, and a QR code label is provided for binding the device and obtaining information by scanning the code with a mobile smart device.

[0029] To achieve the above objectives, the present invention provides the following technical solution:

[0030] A monitoring system for fallen road traffic barriers includes multiple monitoring devices, all of which are connected to the same system cloud platform via IoT cards. The system cloud platform uses an open-source electronic map and has a signal receiving module, a signal sending module, and a calculation module. The signal receiving module receives information from the monitoring devices, the calculation module performs calculations on the feedback information, and the signal sending module sends information to the smart mobile devices of front-end management personnel for notification.

[0031] To achieve the above objectives, the present invention provides the following technical solution:

[0032] A method for monitoring the collapse of road traffic guardrails includes: installation of monitoring devices, positioning marking of guardrails, reception and processing of alarm information, background processing, equipment maintenance and management, and fault recovery steps.

[0033] S1. Monitoring device installation: Install monitoring devices on the load-bearing base of the road traffic guardrail, with the reflective lattice facing the direction of oncoming vehicles, to ensure the guardrail outline warning at night or in the absence of lighting conditions. The monitoring devices are installed using self-tapping screws or rivets for anchoring, with at least one installed every 6 meters. For two-way lanes, they are installed at intervals opposite each other.

[0034] S2. Isolation Fence Positioning Mark: Each monitoring device is marked with a unique QR code label using laser engraving technology. The QR code is generated by a dedicated QR code generator and contains the device ID number.

[0035] The system cloud platform and APP support online drawing of isolation barriers. The online drawn isolation barriers are located on the same map as the on-site isolation barriers. After the monitoring device is installed on the on-site isolation barrier, the device is added and bound to the online isolation barrier by scanning the device's QR code in sequence through the mobile APP. The system cloud platform can also be used to extend the binding between the device and the isolation barrier, the isolation barrier and user information, and management personnel. The system cloud platform sets up a send and receive communication connection for information transmission and sets up the calculation of the isolation barrier collapse status.

[0036] S3. Alarm Information Reception and Handling: When the guardrail collapses, it causes the monitoring device to tilt, and the vibration sensor built into the monitoring device switches from the OFF position to the ON position, waking up the device.

[0037] After the device wakes up, it enters an internal self-test process. When the accelerometer detects a tilt angle exceeding 15 degrees (or the tilt alarm angle set by the system), it reports a tilt alarm for the guardrail. When the tilt angle exceeds 45 degrees (the collapse alarm angle set by the system / the alarm offset), it reports a collapse alarm for the guardrail. When the guardrail encounters a collision, it detects the position offset of the device through the accelerometer. If the offset exceeds 20 cm (the offset set by the system), it sends an offset alarm to the background.

[0038] S4. Backend Processing: After receiving fault information from the frontend, the backend will automatically display the fault location and main fault information on the frontend. At the same time, it will automatically or manually send SMS or APP notifications to the mobile phones of frontend administrators to remind frontend maintenance personnel to handle the faulty facilities as soon as possible. SMS and APP notifications will be sent once a day until the frontend personnel have completed the handling.

[0039] S5. Equipment Maintenance Management: After receiving a fault alert, maintenance personnel should arrive at the scene as soon as possible, first lift up the fallen guardrail, and fix it in its original position as much as possible. If the damage to the facility is irreparable or requires the intervention of the manufacturer, the fault should be reported through the APP.

[0040] Once the equipment is in place, you need to scan the QR code on the monitoring device via the app to clear the warning message and relocate the device.

[0041] S6. Fault Recovery: After the faulty facility is restored, the equipment returns to its initial state and enters sleep standby mode.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] This invention adopts a sensor + intelligent algorithm + transmission mode. The sensor components mainly include a vibration switch and an accelerometer gyroscope. The intelligent algorithm is encapsulated in an embedded chip and senses various states of the front-end sensors through the algorithm. Finally, the algorithm determines whether to report to the platform.

[0044] Because the amount of data generated by the device at one time is relatively small, the data transmission part of the device is handled using NB communication; the platform and APP part are handled using fixed network and mobile Internet technologies to achieve real-time monitoring and timely processing of the system.

[0045] This invention is based on smart Internet of Things (IoT) technology and adopts the shape design of traditional guardrail delineators. It develops an industrial-grade IoT smart delineator, which monitors the delineator in real time through a cloud platform to achieve real-time monitoring and alarm of road traffic guardrails. This can quickly improve the timeliness of handling road traffic guardrail malfunctions, increase the efficiency of front-line staff, reduce labor costs, and save public funds in the long term.

[0046] The outline marker of this invention, when the two ends of the locking block need to be placed in the engaging slot, involves rotating the stop block, causing it to open from the storage slot into a horizontal position, and then inserting the locking block. The stop block's support prevents it from slipping out of the engaging slot. When the stop block is not open, it is stored in the storage slot. A pre-defined gap, denoted as 'd', allows the stop block to be easily opened by placing a finger at the gap and rotating it 90 degrees around its pivot point.

[0047] This invention, due to the installation of a supporting component, allows the delineator body to be temporarily attached to the railing via magnetism when it is affixed. If it is necessary to remove the delineator body from the railing for re-drilling, the magnetic force could cause the retaining block to pull it off the delineator body without securing it. Therefore, a stop or similar device is included to prevent this from happening.

[0048] In this invention, the delineator body mainly serves as a support, the fixing plate is used to fix it to the railing, the engaging groove facilitates engagement and fixation with the locking block, and the magnet placed in the groove facilitates the (delineator body) to be adsorbed and fixed to the railing on the road surface. This allows installers to install the delineator body without holding it with their hands, enabling them to use both hands, which brings convenience to the installers and improves installation efficiency to a certain extent.

[0049] This invention features a reflective lattice that reflects vehicle headlights, a solar panel that absorbs and stores solar energy, converting it into electricity, a mounting opening for easy installation of screws and waterproof sleeves, a through hole at the bottom of the mounting opening for screws to be screwed through a railing for secure mounting, a QR code area for easy scanning and login to control the software, and an LED light to indicate power-on status. A notch near the mounting opening facilitates easy access for installation workers. Attached Figure Description

[0060] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Example:

[0062] Please see Figures 1 to 9 The present invention provides a technical solution:

[0063] In this embodiment of the invention, a monitoring device for the collapse of road traffic guardrails includes a delineator 23, which includes a delineator body 1. Reflective lattice plates 4 are arranged on both sides of the delineator body 1, and a solar panel 8 is provided on the top. A control circuit is provided inside the delineator body 1 for monitoring the collapse of the device. A battery (lithium or nickel-metal hydride battery) mounting area is provided inside the delineator body 1. A battery (lithium or nickel-metal hydride battery) 28 connected to the control circuit is located in the battery (lithium or nickel-metal hydride battery) mounting area. The battery (lithium or nickel-metal hydride battery) 28 is also connected to the solar panel 5, which converts solar energy into electrical energy for storage to maintain long-term operation. The control circuit includes a main chip 24, a vibration sensor 25, and an accelerometer gyroscope 27. All motion sensors 26 are connected to the main chip 24, which is connected to the battery (lithium or nickel-metal hydride battery) 28. The main chip 24 is also connected to an IoT card. When the device is in operation, the monitoring device is installed on the guardrail. The vibration sensor 25 and the accelerometer gyroscope 27 detect the collapse status of the guardrail. The collapse information is uploaded through the IoT card, thereby realizing remote monitoring of the collapse status of the traffic guardrail and obtaining information in a timely manner. The outline specimen also has a built-in Beidou positioning module installed inside. The Beidou positioning module is connected to the collapse monitoring, specifically to the main chip 24. When the monitoring device is blown away by strong winds or knocked away from the guardrail due to a traffic accident, it can be located through Beidou positioning for easy retrieval.

[0064] Specifically, the control circuit also includes a power measurement unit 26, which is connected to the main chip 24 and the battery (lithium or nickel-metal hydride battery) 28. The power measurement unit 26 measures the power level of the battery (lithium or nickel-metal hydride battery) 28 and monitors its voltage. A protective resistor 29 is connected between the power measurement unit 26 and the main chip 24. A voltage regulator unit 30 is also connected between the battery (lithium or nickel-metal hydride battery) 28 and the main chip 24 to ensure normal voltage output when the power level of the battery (lithium or nickel-metal hydride battery) 28 changes. Specifically, the main chip 24 uses an ESP32SOLO embedded chip (other types of MCU chips can also be used), and the vibration sensor... Vibration sensor 25 is model SW520D (other models can also be used). Vibration sensor 25 has a ball-type tilt vibration sensing unidirectional trigger switch. When the guardrail shakes and the tilt angle is greater than 10 degrees, it is in the open circuit OFF state. When the horizontal state of vibration sensor 25 changes tilt and the tilt angle is greater than 45 degrees below horizontal, it is in the closed circuit ON state. The accelerometer gyroscope 27 is model MPU6050 (other models of multi-axis accelerometer gyroscopes or other models of electronic gyroscopes can also be used), and is used to perform collapse detection when the control circuit is working. The IoT card is used to communicate and forward the data detected by accelerometer gyroscope 27.

[0065] Specifically, the main chip 24 is also connected to an LED light to display the power status of the control circuit. The outline marker body 1 is provided with an IoT card slot for inserting an IoT card. The outline marker body 1 is also provided with a product label for recording the basic information of the device. The outline marker body 1 is also provided with a QR code label for scanning the code by a mobile smart device to establish communication connection and obtain information of the device.

[0066] See Figure 8 The monitoring system for fallen road traffic barriers includes multiple monitoring devices, all of which are connected to the same system cloud platform via IoT cards. The system cloud platform uses an open-source electronic map and has a signal receiving module, a signal sending module, and a calculation module. The signal receiving module receives information from the monitoring devices, the calculation module performs calculations on the feedback information, and the signal sending module sends information to the smart mobile devices of the front-end management personnel for notification.

[0067] Using this system can quickly improve the timeliness of handling road traffic barrier malfunctions, increase the efficiency of front-line staff, reduce labor costs, and save public funds in the long term.

[0068] The following is the calculation-related code for the calculation module:

[0069]

[0070]

[0071]

[0072] See Figure 5 The monitoring methods include: installation of monitoring devices, positioning and marking of isolation barriers, reception and handling of alarm information, background processing, equipment maintenance and management, and fault recovery procedures.

[0073] S1. Monitoring device installation: Install monitoring devices on the load-bearing base of the road traffic guardrail, with the reflective lattice plate 4 facing the direction of oncoming vehicles, to ensure the guardrail outline warning at night or in the absence of lighting conditions. The monitoring devices are installed and anchored with self-tapping screws or rivets, with at least one installed on each base, and in two-way lanes, they are installed at intervals opposite each other.

[0074] S2. Software design for guardrails: Develop a guardrail monitoring software platform that includes an electronic map. Based on the actual installation location of the guardrails at the user's site, accurately mark the line segments (or 3D graphics) representing the guardrails on the platform's electronic map.

[0075] S3. Binding of isolation barriers and monitoring devices: Each monitoring device is marked with a unique QR code label using laser engraving technology. The QR code is generated by a dedicated QR code generator and is set as the device ID number.

[0076] After the monitoring device is installed, scan it with a mobile app and bind the monitoring device to the isolation fence in sequence. Binding in sequence can ensure that the installation position of the monitoring device is completely consistent with the position marked on the software platform.

[0077] The system synchronizes and binds equipment with user information, equipment with the system cloud platform, the system cloud platform and the mobile smart devices of management personnel. The system cloud platform sets up a send and receive communication connection for information transmission and sets up a computing system to calculate the collapse state.

[0078] S4. Alarm Information Reception and Handling: When the guardrail collapses, it causes the monitoring device to tilt, and the vibration sensor built into the monitoring device switches from the OFF position to the ON position, waking up the device.

[0079] After the device wakes up, it enters an internal self-test process. If the tilt angle of the accelerometer exceeds 45 degrees (or other angle values ​​set by the system), and the device position offset exceeds 20 cm (or other offset values ​​set by the system) through the accelerometer, the device sends a fault message to the background.

[0080] S5. Backend Processing: After receiving fault information from the frontend, the backend will automatically display the fault location and main fault information on the frontend. At the same time, it will automatically or manually send SMS or APP notifications to the mobile phones of frontend administrators to remind frontend maintenance personnel to handle the faulty facilities as soon as possible. SMS and APP notifications will be sent once a day until the frontend personnel have completed the handling.

[0081] S6. Equipment Maintenance Management: After receiving a fault notification, maintenance personnel should arrive at the scene as soon as possible, first lift up the fallen guardrail, and fix it in its original position as much as possible. If the damage to the facility is beyond repair or requires the intervention of the manufacturer, the fault should be reported through the APP.

[0082] Once the equipment is in place, you need to scan the QR code on the monitoring device via the app to clear the warning message and relocate the device.

[0083] S6. Fault Recovery: After the faulty facility is restored, the equipment returns to its initial state and enters sleep standby mode.

[0084] In this invention, the equipment shell is made of PC engineering plastic. PC engineering plastic has the characteristics of strong water repellency, high and low temperature resistance, corrosion resistance, wear resistance and impact resistance, and is suitable for outdoor road operation environment.

[0085] This invention adopts the overall shape of existing road demarcation markers. The front of the device is divided into left and right sides (A and B sides). The installation positions of reflective lattices or solar panels can be set according to the relative position of the device on the road guardrail. The device model is defined by its length and width, such as: LB155A (A side is a reflective lattice, B side is a solar panel), LB155B (B side is a reflective lattice, A side is a solar panel), LB155AB (solar panel on top, both A and B sides are reflective lattices). The reflective lattice colors include yellow and white. The solar panel is embedded opposite the reflective lattice for charging the device's built-in lithium battery.

[0086] This invention features a low-power design. The standard device is equipped with a 3000mAh 18650 lithium battery (other types and models of rechargeable batteries, such as rechargeable nickel-metal hydride batteries, can be configured as needed), and is simultaneously powered by an auxiliary solar panel. The power supply voltage is 1.2V-5V, and the static current in normal sleep mode is ≤200uA; the maximum operating current during wake-up is ≤120mA. The device can achieve an ultra-long standby time of over 3 years in sleep mode; the auxiliary solar panel can provide continuous power for over 8 years, thus ensuring the normal operation of the device in complex outdoor road environments.

[0087] Circuit board design

[0088] The device's circuit board uses a 4-layer PCB board, which is 110mm long and 35mm wide. It contains one MCU chip, one copper ball-type vibration sensor, one accelerometer gyroscope, one surface-mount LED indicator, and one NB-IoT communication module with built-in NB card.

[0104] 5) LED lights

[0105] The status indicator light uses a single yellow surface-mount LED.

[0106] This invention provides a conveniently maintained delineator 23, comprising:

[0107] The contour marker body 1 has a mounting plate 2 at its bottom;

[0108] Fixing plate 15, which can be detached and installed from mounting plate 2;

[0109] The engaging groove 16 is formed on the fixing plate 15 and near both sides, and the engaging groove 16 has a fixing groove 17 between them.

[0110] The two ends of the locking block 3 are located in the locking groove 16, and the middle part is located in the fixing groove 17;

[0111] Magnet 10, the magnet 10 is installed at the bottom of the card block 3;

[0112] The inner wall of the engagement groove 16 has a lifting member 18 for lifting the locking block 3 located in the engagement groove 16.

[0113] Specifically, the middle part of the card block 3 and the corresponding part of the mounting plate 2 are provided with screw holes 20, and the fixing plate 15 and the mounting plate 2 are disassembled and assembled by bolts 9 and screw holes 20.

[0114] Specifically, the fixing plate 15 has a groove 21 for receiving the head of the bolt 9. After the bolt 9 is installed, the head of the bolt 9 can be received in the groove 21, so as not to affect or interfere with the adsorption or installation of the delineator body 1 on the railing.

[0115] In this invention, the card block 3 is a block made of soft rubber, roughly T-shaped. It has placement grooves at both ends of the bottom for fixing magnets 10 within these grooves. Specifically, two to four magnets 10 can be placed at each end of the bottom; other numbers are also possible, depending on the specific application. The magnets 10 can be circular, strip-shaped, etc.

[0116] In this invention, the middle portion of the locking block 3 has a screw hole 20, and correspondingly, the bottom of the mounting plate 2 also has a screw hole 20. After the locking block 3 is installed on the fixing plate 15, the bolt 9 is screwed into the screw hole 20, which allows the locking block 3, together with the fixing plate 15, to be installed on the bottom of the mounting plate 2. Since the delineator body 1 is reinstalled on the railing, magnets 10 are installed at both ends of the locking block 3, so the delineator body 1 is attracted to the railing by the magnets 10, which facilitates drilling or, after drilling, using bolts to finally fix the delineator body 1 to the railing. Of course, it is also possible to install the bolt 9 on the middle portion of the locking block 3, and then use bolts to further fix the fixing plate 15 and the mounting plate 2.

[0117] In this invention, when the two ends of the locking block 3 are placed in the locking groove 16, a supporting component 18 is installed in the locking groove 16 to prevent the locking block 3 from falling in.

[0118] Specifically, the lifting component 18 includes a stop block 11, which is rotatably connected to the engaging groove 16. When the stop block 11 is open, its bottom surface is parallel to the bottom surface of the fixing plate 15. When the stop block 11 is closed, its bottom surface is parallel to or flush with the side surface of the engaging groove 16. The engaging groove 16 has a storage groove 12 on its side. A rotating shaft 13 is installed at the bottom of the stop block 11, with both ends of the rotating shaft 13 rotatably mounted on the storage groove 12. When the stop block 11 is closed, there is a gap 19 between it and the top of the storage groove 12. The lower ends of the locking block 3 have locking grooves 14 that are adapted to the stop block 11.

[0119] like Figures 3 to 5 As shown, when the two ends of the locking block 3 need to be placed in the engaging slot 16, the stop block 11 is rotated, causing the stop block 11 to open from the storage slot 12 and become horizontal. Then, the locking block 3 is inserted. Due to the support of the stop block 11, it is prevented from leaking out of the engaging slot 16. When the stop block 11 is not open, it is stored in the storage slot 12. By leaving a gap 19, the gap being d, it is easy to extend a finger to the gap 19 when the stop block 11 needs to be opened, thereby rotating the stop block 11 90 degrees around the pivot 13 to open it.

[0120] In this invention, due to the installation of the supporting component 18, when the delineator body 1 is attached to the railing, the magnet 10 can temporarily attract the delineator body 1 to the railing. If it is necessary to remove the delineator body 1 from the railing for re-drilling, the magnetic force may cause the locking block 3 to be pulled off the delineator body 1 without securing it. Therefore, the stop block 11 is provided to prevent this from happening.

[0121] Specifically, the contour marker body 1 has a reflective lattice 4 on its side and a solar panel 8 on its top.
