[0001] Relevant publicly available cross-references

[0002] This disclosure claims priority to Chinese Patent Publication No. 2024119199114, filed on December 25, 2024, entitled "A Highway Defect Detection Device, Repair Device, Highway Defect Detection and Repair System and Method Thereof", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of highway defect inspection and repair technology, and more specifically, to a highway defect detection device, a repair device, a highway defect detection and repair system, and a method thereof. Background Technology

[0004] With the advancement of science and technology and the continuous development of engineering techniques, highway repair technology has made significant progress. However, facing complex and ever-changing geographical environments, especially in high-altitude and cold regions, existing technologies still face many challenges. The widespread presence of permafrost and seasonally frozen soil in high-altitude and cold regions poses immense difficulties for highway construction and maintenance. Permafrost is disturbed during construction, increasing the risk of thawing, while the frost heave and thawing of seasonally frozen soil during the winter-spring transition causes significant changes in the roadbed fill, leading to a series of engineering defects.

[0005] Currently, the main problem with highway repair technology in high-altitude and cold regions is that the roadbed fill undergoes frost heave and thaw settlement under freeze-thaw cycles, leading to pavement defects such as transverse cracks, longitudinal cracks, and frost heave. These defects are not caused by a single freeze-thaw cycle, but are the result of long-term accumulation. Due to the lack of effective real-time monitoring methods, highway maintenance departments often have to rely on regular inspections to detect problems, but by then the pavement has often cracked over a large area, the number of frost heave points has increased, and the repair costs are high with unsatisfactory results. Summary of the Invention

[0006] The purpose of this disclosure is to provide a highway defect detection device, a repair device, a highway defect detection and repair system, and a method thereof. The highway defect detection and repair system can detect and repair highway defects in a timely manner, prevent the expansion of highway defects, and reduce highway repair costs.

[0012] The highway repair device provided in this disclosure features a drilling component that allows for the rapid drilling of injection holes in the areas of the highway to be repaired. A leveling component ensures the injection holes are smoothed after the repair material is injected. This guarantees a smooth and aesthetically pleasing repaired road surface, while also improving the road's performance and safety.

[0013] In one embodiment, the injection assembly includes a storage container and a delivery pipe. The storage container is mounted on the frame and stores road repair material; one end of the delivery pipe is connected to the storage container, and the other end is used to inject road repair material into the injection port.

[0014] In one embodiment, the filling assembly further includes an environmental maintainer disposed within the storage container, the environmental maintainer being used to adjust the environmental parameters within the storage container to a preset range.

[0015] In one embodiment, the filling assembly further includes a low-material alarm disposed in the storage container, the low-material alarm being used to detect the amount of road repair material stored in the storage container.

[0016] Thirdly, embodiments of this disclosure also provide a highway defect detection and repair system, including a support frame, an energy harvesting device, an energy storage device, a communication device, a highway defect detection device, and a highway defect repair device. The support frame is fixedly installed; the number of highway defect detection devices is at least two; the energy harvesting device is mounted on the support frame and is used to acquire electrical energy; the energy storage device is electrically connected to the energy harvesting device, and the electrical energy acquired by the energy harvesting device is stored in the energy storage device, which is pre-embedded in the roadbed; the energy storage device is electrically connected to the highway defect detection device and the highway defect repair device, and provides electrical energy to both the highway defect detection device and the highway defect repair device; the communication device is mounted on the support frame, and is electrically connected to the energy storage device; the energy storage device supplies electrical energy to the communication device, and the communication device communicatively connects the highway defect detection device and the highway defect repair device.

[0017] The highway defect detection and repair system provided in this disclosure acquires electrical energy through an energy harvesting device and stores it in an energy storage device, providing a continuous power supply for the entire system. This reduces dependence on external power sources and improves the system's reliability and applicability. The highway defect detection device can detect the areas of the highway to be repaired in real time and transmit the information to the highway defect repair device via a communication device. This intelligent detection and repair process improves work efficiency, reduces the cost of manual inspection and repair, and enables timely detection and treatment of highway defects, ensuring highway safety and smooth traffic flow. After receiving information about the areas to be repaired, the highway defect repair device can quickly move to the designated location and complete the repair work through drilling, material injection, and leveling steps.

[0019] Fourthly, embodiments of this disclosure also provide a method for detecting and repairing highway defects, implemented using a highway defect detection and repair system as described in any of the above embodiments, the method comprising:

[0020] The roadbed is divided into at least one detection area, and at least two highway defect parameter collection points are set in each detection area. The at least two collection points are distributed at intervals along the depth direction and / or length direction of the roadbed.

[0021] The highway distress parameters at each collection point are obtained. These parameters include moisture migration and distribution parameters, stress change parameters, and displacement parameters of the highway distress detection device in the linear and rotational directions.

[0022] Based on the highway damage parameters, determine whether each of the tested areas is subject to frost heave and / or thaw settlement.

[0023] If the detected area exhibits the aforementioned frost heave and / or thaw settlement, then the detected area exhibiting frost heave and / or thaw settlement is determined as the area to be repaired, and the depth of the area to be repaired is obtained.

[0024] Drill holes in the area to be repaired and inject road repair material, then level and compact the injection site.

[0025] The highway defect detection and repair method disclosed herein, through detailed regional division of the roadbed and the establishment of multiple defect parameter collection points within each region, enables precise location and comprehensive detection of highway defects. This method acquires multi-dimensional parameters, including moisture migration distribution, stress changes, and the displacement of the detection device in both linear and rotational directions. Comprehensive analysis of these parameters provides rich data support for accurate diagnosis of highway defects, making the detection more precise and reliable. By acquiring the defect parameters and determining whether defects such as frost heave or thaw settlement occur in each detection area, the areas to be repaired are identified. This judgment mechanism helps to promptly detect and treat defects, thereby enabling preventative repair measures to prevent further deterioration. After determining the areas to be repaired, holes are drilled in the repair areas, repair material is injected, and the injected areas are leveled and compacted. This targeted repair method not only improves repair efficiency but also ensures repair quality and extends the service life of the highway.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0040] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0041] This disclosure provides a highway defect detection device 1700, a repair device, a highway defect detection and repair system 1000, and a method thereof. The method can be implemented using the highway defect detection and repair system 1000. As shown in FIG1, the highway defect detection and repair system 1000 includes a highway defect detection device 1700 and a highway defect repair device 1800. The highway defect detection device 1700 is pre-embedded in the roadbed 2300 of the highway 2000. For example, as shown in Figure 1, Highway 2000 includes a surface layer 2100, a base layer 2200, and a subgrade 2300. The subgrade 2300 is mainly composed of earth and rock fill. During road construction, it requires repeated compaction, especially in fill areas, where multiple watering and compaction are necessary until the subgrade 2300 reaches the predetermined compaction degree. The stability of the subgrade 2300 affects the stability of the surface layer 2100. The base layer 2200 is a layered structure constructed on the surface of the subgrade 2300 (or subbase) using a single material laid in layers according to certain technical measures. The quality of its materials directly affects the quality and performance of the road surface. The base layer 2200 is the load-bearing layer of the entire road, playing a role in stabilizing the road surface. The road base layer 2200 is divided into an inorganic binder stabilized base layer 2200 and a crushed / gravel base layer 2200. The surface layer 2100 of Highway 2000 is mainly composed of asphalt mixture and has a certain degree of brittleness. The base layer 2200 is laid below the surface layer 2100.

[0042] As shown in Figure 2, the highway defect detection device 1700 provided in the embodiments of this disclosure includes a housing 1710, a first positioning component 1720, a moisture sensor 1730, and a stress sensor 1740.

[0043] The housing 1710 is embedded in the roadbed 2300 of the highway 2000. For example, the housing 1710 is made of stainless steel. Of course, the housing 1710 can also be made of other materials, such as titanium alloy, copper alloy, etc.

[0044] The first positioning component 1720 is disposed within the housing 1710. The first positioning component 1720 is used to locate the position of the highway defect detection device 1700. The placement of the first positioning component 1720 allows for precise positioning of the highway defect detection device 1700, facilitating accurate analysis and treatment of defects in specific areas.

[0045] The body of the moisture sensor 1730 is disposed within the housing 1710, and the detection end of the moisture sensor 1730 extends outside the housing 1710. The moisture sensor 1730 is used to detect changes in moisture within the roadbed 2300. Exemplarily, the moisture sensor 1730 includes, but is not limited to, a capacitive moisture sensor 1730, a resistive moisture sensor 1730, a microwave moisture sensor 1730, or an electrochemical humidity sensor, etc.

[0046] A key condition for frost heave is that the moisture content exceeds a certain threshold. When the soil is dry, frost heave will not occur even if the temperature drops sharply. The moisture sensor 1730 monitors moisture changes, and combined with the moisture monitoring results of the adjacent highway defect detection device 1700, the moisture changes inside the roadbed 2300 can be known in a timely manner. This allows for timely identification of any leakage points inside the roadbed 2300 and prompt repair.

[0047] The moisture sensor 1730 can monitor changes in moisture inside the roadbed 2300. Once the moisture content is detected to exceed the threshold for frost heave, it can issue an early warning and take measures to prevent frost heave disease.

[0048] The stress sensor 1740 has its body housed within the housing 1710, with its detection end extending outside the housing 1710. The stress sensor 1740 is used to detect stress changes within the roadbed 2300. Exemplarily, the stress sensor 1740 includes, but is not limited to, a metal strain gauge type stress sensor 1740, a semiconductor strain gauge type stress sensor 1740, a piezoelectric type stress sensor 1740, a piezoresistive type stress sensor 1740, or a fiber optic grating type stress sensor 1740.

[0049] The stress sensor 1740 mainly monitors the frost heave force generated in the roadbed 2300 in real time. The stress sensor 1740 is set with a threshold. Stress changes within the safe threshold range may be normal loads from passing vehicles. If the stress value and direction change drastically, frost heave force may be generated. The frost heave force is determined by combining the changes in moisture content. If frost heave force is generated and moisture content increases sharply, it indicates that frost heave has occurred and timely repair is required.

[0050] By monitoring stress changes in the roadbed 2300 and combining this with moisture data, the stress sensor 1740 can comprehensively determine whether frost heave has occurred, thereby promptly detecting and addressing frost heave damage and reducing its impact on the highway 2000.

[0051] Moisture sensor 1730 and stress sensor 1740 monitor changes in moisture and stress within the roadbed 2300 in real time, providing a large amount of real-time data, which helps to detect abnormalities in the roadbed 2300 in a timely manner.

[0052] The highway defect detection device 1700, through its moisture sensor 1730 and stress sensor 1740, collects data from various aspects of the highway 2000, accurately analyzes the data, and makes highway defect detection more automated and intelligent. The first positioning component 1720 precisely locates the defects, reducing the frequency and cost of manual inspections and improving the efficiency of highway maintenance. By promptly detecting and addressing highway defects, especially potentially destructive ones such as frost heave, it effectively prevents further expansion and deterioration, thereby extending the service life of the highway. Timely detection and repair of highway defects can reduce safety hazards such as road surface damage and collapse, improve the safety performance of the highway, and ensure driving safety.

[0053] As shown in Figure 2, the highway defect detection device 1700 also includes a rotation sensor 1750 and a translation sensor 1760.

[0054] A rotation sensor 1750 is disposed within the housing 1710, and the rotation sensor 1750 is used to detect displacement in the rotational direction of the housing 1710. For example, the rotation sensor 1750 may be a rotary encoder, a tilt sensor, etc.

[0055] A translation sensor 1760 is disposed within the housing 1710, and the translation sensor 1760 is used to detect the linear displacement of the housing 1710. Exemplarily, the translation sensor 1760 is, for example, a linear displacement sensor, an acceleration sensor, or a photoelectric translation sensor, etc.

[0056] As shown in Figures 1 and 2, during use, the highway defect detection device 1700 is installed in the roadbed 2300, and the housing 1710 is in close contact with the roadbed 2300. Excessive frost heave force on the roadbed 2300 will cause the housing 1710 to rotate and move. Therefore, the rotation direction and linear displacement of the housing 1710 are also important evidence for comprehensively judging the frost heave.

[0057] By using the rotation sensor 1750, the displacement of the shell 1710 in the rotational direction is collected, and by using the translation sensor 1760, the displacement of the shell 1710 in the linear direction is collected, which helps to improve the accuracy of frost heave determination.

[0058] Traditional roadbed defect detection may rely on a single type of sensor, while this embodiment combines multiple sensors to achieve multi-dimensional and comprehensive monitoring of the roadbed condition. This multi-dimensional monitoring method can more comprehensively reflect the actual condition of the roadbed and helps to promptly identify and address potential problems.

[0059] In the complex environment of the highway 2000, various factors (such as temperature changes, soil moisture, vehicle load, etc.) can affect the roadbed 2300. By simultaneously monitoring the rotational and translational displacement of the housing 1710, the system can more accurately identify and distinguish these influencing factors, thereby enhancing its adaptability and robustness to environmental changes.

[0060] Based on real-time data provided by the rotation sensor 1750 and the translation sensor 1760, the highway defect detection device 1700 can establish a more accurate early warning and response mechanism. Once abnormal displacement is detected, the highway defect detection device 1700 can immediately trigger an early warning to take necessary repair measures, thereby effectively preventing the further development and expansion of defects.

[0061] As shown in Figure 2, in one embodiment, the highway defect detection device 1700 includes a first control component, a first communication component, and a first energy storage component 1770.

[0062] The first control component is electrically connected to the first positioning component 1720, the moisture sensor 1730, and the stress sensor 1740; the first control component is used to control the start and stop of the first positioning component 1720. The moisture sensor 1730 can send the detection result to the first control component; the stress sensor 1740 can send the detection result to the first control component. Exemplarily, the first control component includes, but is not limited to, a central processing unit (CPU), a programmable logic controller (PLC), or an electronic device with logic control functions.

[0063] The first communication component is electrically connected to the first control component, and the first control component establishes a communication connection with external devices through the first communication component; the first control component sends the received detection results to the external devices through the first communication component, so as to issue highway 2000 defect alarm information through the external devices.

[0064] For example, external devices may be alarms, smart terminals, etc. Alarms may be sound alarms, light alarms, or audible and visual alarms. Smart terminals may be mobile phones, computers, tablets, or other engineering equipment platforms.

[0065] The first energy storage component 1770 is electrically connected to the first control component and the first communication component, and the first energy storage component 1770 supplies power to the first control component and the first communication component.

[0066] For example, the first energy storage assembly 1770 is configured by arranging a plurality of energy storage stacks, which are energy storage cells arranged in a predetermined direction. The energy storage cells are, for example, secondary batteries such as nickel-metal hydride batteries or lithium-ion batteries. The energy storage cells can use liquid electrolytes or solid electrolytes. Alternatively, the energy storage cells can also be configured as unit capacitors capable of storing electricity.

[0067] For example, the first positioning component 1720 is integrated with the first communication component. However, in another embodiment, the first positioning component 1720 and the first communication component are separately arranged, and the first positioning component 1720 integrates a communicator, such as a first wired communication module and / or a first wireless communication module. The first communication component includes a second wired communication module and / or a second wireless communication module.

[0068] For example, the first wired communication module and the second wired communication module include, but are not limited to: Ethernet module, USB (Universal Serial Bus) module, serial port module, IEEE 1394 / FireWire module or fiber optic module, etc.

[0069] The first and second wireless communication modules include, but are not limited to: cellular communication modules, Wi-Fi modules, Bluetooth modules, ZigBee modules, LoRa (Long Range) modules, NB-IoT (Narrowband Internet of Things) modules, UWB (Ultra-Wideband) modules, RFID (Radio Frequency Identification) modules, infrared communication modules, satellite communication modules, RF wireless data communication modules, or 2.4GHz wireless transceiver modules, etc.

[0070] As shown in Figure 2, in one embodiment, the highway defect detection device 1700 further includes a power supply line 1780. One end of the power supply line 1780 is electrically connected to an external power source, and the other end of the power supply line 1780 is electrically connected to a first energy storage component 1770. The first energy storage component 1770 obtains electrical energy from the external power source through the power supply line 1780. For example, the external power source may be the power grid, the energy storage device 1300, etc.

[0071] As shown in Figure 3, the highway repair device 1800 provided in the embodiments of this disclosure includes a frame 1810, a moving component 1820, a drilling component 1830, a material injection component 1840, and a leveling component 1850.

[0072] A moving component 1820 is mounted on a frame 1810 and is used to move the frame 1810. Exemplarily, the moving component 1820 includes casters 1822 and a drive unit 1824. The casters 1822 and the drive unit 1824 are mounted on the frame 1810 and are drive-driven. The drive unit 1824 drives the casters 1822 to rotate, which in turn moves the frame 1810. Simultaneously, the casters 1822 can also steer to change the direction of movement of the frame 1810. The drive unit 1824 includes a drive motor, which is drive-driven to the casters 1822.

[0073] By incorporating a mobile component 1820 with casters 1822, the entire device can be easily moved and steered, facilitating rapid positioning and movement at the road 2000 repair site.

[0074] A drilling assembly 1830 is mounted on a frame 1810 and is used to drill injection holes in the parts of the road 2000 to be repaired. Exemplarily, the drilling assembly 1830 includes a drilling motor and a drill bit. The drilling motor is movably mounted on the frame 1810, and its output end is connected to the drill bit. Rotation of the drilling motor drives the drill bit to rotate. The drilling motor moves closer to the repair location on the road 2000, causing the drill bit to move closer to the repair location on the road 2000. The rotation of the drilling motor drives the drill bit to rotate, thus rotating the road 2000 out of the injection hole.

[0075] Injection assembly 1840 is mounted on frame 1810 and is used to inject road repair material into injection holes. Exemplarily, road repair materials include, but are not limited to, asphalt, epoxy resin, asphalt concrete, etc.

[0076] The leveling assembly 1850 includes a leveling component 1852 and a first driver 1854. The first driver 1854 is mounted on a frame 1810, and the leveling component 1852 is movably mounted on the frame 1810. The movement of the leveling component 1852 can flatten the injection hole after the road repair material has been injected. The first driver 1854 is driven by the leveling component 1852 and is used to drive the leveling component 1852 to move. The first driver 1854 is, for example, a vibratory motor, which is driven by the leveling component 1852. Exemplarily, the leveling component 1852 includes a drive rod and a leveling plate. One end of the drive rod is driven by the vibratory motor, and the other end of the drive rod is fixedly mounted with the leveling plate. The vibratory motor drives the leveling plate to reciprocate through the drive rod, and the leveling plate is used to flatten the injection hole after the repair material has been injected.

[0077] By incorporating a mobile assembly 1820 with casters 1822, the highway repair device 1800 can easily move quickly and be precisely positioned at the highway 2000 repair site. The casters 1822 not only enable the device to move forward, backward, left, and right, but also allow for flexible steering, thus greatly improving the device's mobility and positioning accuracy on site.

[0078] The design of the drilling assembly 1830 enables the highway repair device 1800 to quickly drill injection holes in the repaired areas of the highway 2000. The combination of the drilling motor and drill bit is simple and efficient, easily handling highway 2000 surfaces of varying hardness and material, achieving fast and accurate drilling operations, and facilitating subsequent repair work.

[0079] The 1850 leveling component, through the coordinated action of a vibratory motor and a leveling plate, enables the smoothing of the injection holes after the repair material is injected. This design not only ensures a smooth and aesthetically pleasing repaired road surface but also improves the road's performance and safety.

[0080] The highway defect repair device 1800 provided in the embodiments of this disclosure realizes integrated functions such as efficient movement, precise positioning, rapid drilling, diverse material injection, and leveling repair, which greatly improves the efficiency and quality of highway defect repair.

[0081] As shown in Figure 3, in one embodiment, the filling assembly 1840 includes a storage container 1842 and a delivery pipe 1844.

[0082] The storage container 1842 is mounted on the frame 1810 and contains road repair materials.

[0083] For example, the storage container 1842 is provided with a feeding port, through which road repair material can be added to the storage container 1842. A feeding cover 1860 is provided on the feeding port, which is provided so that the feeding port can be closed or opened.

[0084] For example, the storage container 1842 is, for example, a storage tank, a storage bin, or a storage bucket.

[0085] One end of the conveying pipe 1844 is connected to the storage container 1842, and the other end of the conveying pipe 1844 is used to inject road repair material into the injection hole.

[0086] The injection assembly 1840 also includes a pump 1841, which is mounted on the frame 1810 and connected to the delivery pipe 1844. The pump 1841 is used to pressurize and deliver road repair materials.

[0087] In one embodiment, the highway repair device 1800 further includes a second control component electrically connected to a pump 1841, which controls the start and stop of the pump 1841. The second control component is also electrically connected to a first drive 1854, which controls the start and stop of the first drive 1854 and the steering of the casters 1822.

[0088] The second control component includes, but is not limited to, a central processing unit (CPU), a programmable logic controller (PLC), or an electronic device with logic control functions.

[0089] In one embodiment, the highway damage repair device 1800 further includes a second positioning component, which is electrically connected to a second control component.

[0090] In one embodiment, the highway damage repair device 1800 further includes a second communication component, which is electrically connected to a second control component, and the second control component communicates with external devices through the second communication component.

[0091] For example, the second communication component includes a wired communication module and / or a wireless communication module. The wired communication module includes, but is not limited to, an Ethernet module, a USB (Universal Serial Bus) module, a serial port module, an IEEE 1394 / FireWire module, or a fiber optic module. The wireless communication module includes, but is not limited to, a cellular communication module, a Wi-Fi module, a Bluetooth module, a ZigBee module, a LoRa (Long Range) module, an NB-IoT (Narrowband Internet of Things) module, a UWB (Ultra-Wideband) module, an RFID (Radio Frequency Identification) module, an infrared communication module, a satellite communication module, an RF wireless data communication module, or a 2.4GHz wireless transceiver module.

[0092] In one embodiment, the highway repair device 1800 further includes a second energy storage component. The second energy storage component is electrically connected to a second control component, a second communication component, and a second positioning component, and supplies power to these components. The second energy storage component is also electrically connected to other electrical components in the highway repair device 1800, such as a material shortage alarm 1848, an environmental maintainer 1846, and a pump 1841, providing power for the operation of the highway repair device 1800.

[0093] As shown in Figure 3, in one embodiment, the filling assembly 1840 further includes an environmental maintainer 1846, which is disposed within the storage container 1842. The environmental maintainer 1846 is used to regulate the environmental parameters within the storage container 1842 within a preset range. The environmental maintainer 1846 is electrically connected to a second control assembly, which controls the start and stop of the environmental maintainer 1846.

[0094] For example, the environmental maintainer 1846 is a humidifier, which is used to adjust the humidity parameter in the storage container 1842. When the humidity in the storage container 1842 is less than the preset humidity, the humidifier is activated to humidify the storage container 1842. In another embodiment, the environmental maintainer 1846 is a heater, which is used to adjust the temperature parameter in the storage container 1842. When the temperature in the storage container 1842 is less than the preset temperature, the heater is activated to heat the storage container 1842. However, in another embodiment, the environmental maintainer 1846 is both a humidifier and a heater.

[0095] The humidity parameter in the storage container 1842 is sensed by a humidity sensor. The humidity sensor is electrically connected to the second control component. The humidity sensor detects the humidity parameter in the storage container 1842 and sends the detection result to the second control component. The second control component controls the start and stop of the humidifier according to the detection result.

[0096] The temperature parameter in the storage container 1842 is sensed by a temperature sensor. The temperature sensor is electrically connected to the second control component. The temperature sensor detects the temperature in the storage container 1842 and sends the detection result to the second control component. The second control component controls the start and stop of the heater according to the detection result.

[0097] As shown in Figure 3, in one embodiment, the filling assembly 1840 further includes a material shortage alarm 1848, which is disposed in the material storage container 1842 and is used to detect the amount of road repair material stored in the material storage container 1842.

[0098] For example, the material shortage alarm 1848 is a pressure sensor, which is electrically connected to the second control component. The pressure sensor is used to detect the weight of the storage container 1842 and send the detection result to the second control component.

[0099] When the pressure sensor detects that the amount of road repair material is less than or equal to the preset storage amount, the second control component sends an alarm to external devices through the second communication component.

[0100] Thirdly, as shown in FIG1, the highway defect detection and repair system 1000 provided in the embodiments of this disclosure includes a frame 1100, an energy capture device 1200, an energy storage device 1300, a communication device 1400, a highway defect detection device 1700 as described in any of the above embodiments, and a highway defect repair device 1800 as described in any of the above embodiments.

[0101] As shown in Figure 1, the support frame 1100 is fixedly installed on the surface layer 2100 of the highway 2000.

[0102] At least two highway defect detection devices 1700 are provided in the roadbed 2300, and at least two of the highway defect detection devices 1700 are sequentially distributed along the depth direction and / or along the length direction of the roadbed 2300. Exemplarily, the depth direction of the roadbed 2300 is parallel to the vertical direction, and the length direction of the roadbed 2300 is the extension direction of the highway 2000. Exemplarily, two highway defect detection devices 1700 are provided in the roadbed 2300. However, in another embodiment, three, four, five, or fifty highway defect detection devices 1700 may also be provided in the roadbed 2300.

[0103] An energy harvesting device 1200 is mounted on a support frame 1100 and is used to harvest electrical energy. Exemplarily, the energy harvesting device 1200 includes, but is not limited to, wind turbine generators, hydroelectric generators, and solar cells.

[0104] The energy storage device 1300 is electrically connected to the energy harvesting device 1200. The electrical energy acquired by the energy harvesting device 1200 is stored in the energy storage device 1300. The energy storage device 1300 is pre-embedded in the roadbed 2300. The energy storage device 1300 is electrically connected to the highway defect detection device 1700 and the highway defect repair device 1800. The energy storage device 1300 provides electrical energy to the highway defect detection device 1700 and the highway defect repair device 1800.

[0105] For example, the energy storage device 1300 is configured by arranging multiple energy storage stacks, which are energy storage units arranged in a predetermined direction. The energy storage units are, for example, secondary batteries such as nickel-metal hydride batteries or lithium-ion batteries. The energy storage units can use liquid electrolytes or solid electrolytes. Alternatively, the energy storage units can also be configured as unit capacitors capable of storing electricity.

[0106] The communication device 1400 is mounted on the support frame 1100. The communication device 1400 is electrically connected to the energy storage device 1300. The energy storage device 1300 supplies power to the communication device 1400. The communication device 1400 is also connected to the highway defect detection device 1700 and the highway defect repair device 1800.

[0107] The energy storage device 1300 supplies electrical energy to the highway defect detection device 1700. For example, the energy storage device 1300 is electrically connected to the first energy storage component 1770 of the highway defect detection device 1700 via a power supply line 1780.

[0108] In use, the highway defect detection and repair system 1000 provided in this disclosure detects the area to be repaired on the highway 2000 via the highway defect detection device 1700 and transmits the area to be repaired to the highway defect repair device 1800 via the communication device 1400. Initially, the highway defect repair device 1800 is charged at the support frame 1100. After receiving the information about the area to be repaired, the highway defect repair device 1800 moves to the area via the moving component 1820 and drills an injection hole in the area via the drilling component 1830. The injection component 1840 injects highway repair material into the injection hole, and then the leveling component 1850 levels and compacts the injection hole. Then, the highway defect repair device 1800 returns to the support frame 1100 to charge.

[0109] The highway defect detection and repair system 1000 provided in the embodiments of this disclosure obtains electrical energy through an energy harvesting device 1200 (such as a wind turbine, a hydroelectric generator, and solar cells) and stores it in an energy storage device 1300 to provide a continuous power supply for the entire system. This design enables the highway defect detection and repair system 1000 to operate independently in remote areas or areas lacking stable power sources, reducing dependence on external power sources and improving the reliability and applicability of the system.

[0110] The highway defect detection device 1700 can detect the areas of highway 2000 that need repair in real time and send the information to the highway defect repair device 1800 via the communication device 1400. This intelligent detection and repair process improves work efficiency, reduces the cost of manual inspection and repair, and can promptly detect and address defects in highway 2000, ensuring the safety and smooth flow of traffic on highway 2000.

[0111] After receiving information about the area to be repaired, the highway repair device 1800 can quickly move to the designated location and complete the repair work through steps such as drilling, filling, and leveling. This streamlined repair method improves repair efficiency, reduces repair time, and helps to quickly restore the highway to normal service condition.

[0112] At the same time, timely repair of road damage can also help extend the service life of road 2000 and reduce resource waste and environmental pollution.

[0113] The highway defect detection and repair system 1000 provided in the embodiments of this disclosure achieves beneficial effects such as self-sufficient energy supply, intelligent detection and repair, efficient repair process, sustainability and environmental protection.

[0114] As shown in Figure 1, in one embodiment, the highway defect detection and repair system 1000 further includes a first connection terminal 1500 and a second connection terminal 1600.

[0115] The first connection terminal 1500 is disposed on the support frame 1100, and the first connection terminal 1500 is electrically connected to the energy storage device 1300.

[0116] As shown in Figures 1 and 3, the second connection terminal 1600 is disposed on the highway repair device 1800. The highway repair device 1800 is electrically connected to the first connection terminal 1500 through the second connection terminal 1600, so that the highway repair device 1800 is electrically connected to the energy storage device 1300.

[0117] Initially, the highway damage repair device 1800 is located at the support frame 1100, with the first connecting terminal 1500 and the second connecting terminal 1600 connected. When the highway damage repair device 1800 receives information about the area to be repaired, the first connecting terminal 1500 and the second connecting terminal 1600 are disconnected. After the highway damage repair device 1800 has completed the repair of the highway 2000, it returns to the support frame 1100 and electrically connects the first connecting terminal 1500 and the second connecting terminal 1600.

[0118] Fourthly, the highway defect detection and repair method provided in the embodiments of this disclosure, as shown in Figure 4, includes:

[0119] S100: Divide the interior of the roadbed 2300 into at least one detection area, and set at least two highway defect parameter collection points in each detection area. The at least two collection points are distributed sequentially and at intervals along the depth direction and / or length direction of the roadbed 2300.

[0120] By meticulously dividing the interior of the 2300m roadbed into zones and setting up multiple defect parameter collection points within each zone, this method enables precise location and comprehensive detection of defects along the 2000m road. This setup ensures that no potential defect can escape detection, whether in the depth or length direction.

[0121] S200: Acquire highway distress parameters at each collection point. These parameters include moisture migration and distribution parameters, stress change parameters, and displacement parameters of the highway distress detection device 1700 in the linear and rotational directions. Exemplarily, the highway distress detection device 1700 provided in this embodiment of the present disclosure acquires moisture migration and distribution parameters, stress change parameters, and displacement parameters of the highway distress detection device 1700 in the linear and rotational directions. Moisture migration and distribution parameters are acquired using a moisture sensor 1730, stress change parameters are acquired using a stress sensor 1740, displacement parameters of the highway distress detection device 1700 in the rotational direction are acquired using a rotation sensor 1750, and displacement parameters of the highway distress detection device 1700 in the linear direction are acquired using a translation sensor 1760.

[0122] S300: Based on highway defect parameters, determine whether each detection area experiences frost heave and / or thaw settlement. Exemplarily, the first control component is implemented using the highway defect detection device 1700 provided in an embodiment of this disclosure.

[0123] S400: If there is a detection area where frost heave and / or thaw settlement have occurred, the detection area where frost heave and / or thaw settlement have occurred is determined as the area to be repaired, and the depth of the area to be repaired is obtained. The depth of the area to be repaired is obtained through the highway defect detection device 1700 provided in the embodiments of this disclosure.

[0124] S500: Drill holes in the area to be repaired and inject highway repair material, then level and compact the injection site. The highway repair device 1800 provided in this disclosure achieves the drilling of holes and injection of highway repair material into the repair area, followed by leveling and compaction of the injection site.

[0125] The highway defect detection and repair method disclosed herein, through detailed regional division of the roadbed 2300 and the establishment of multiple defect parameter collection points within each region, enables precise location and comprehensive detection of highway defects 2000. This method acquires multi-dimensional parameters, including moisture migration distribution, stress changes, and the displacement of the detection device in both linear and rotational directions. Comprehensive analysis of these parameters provides rich data support for accurately diagnosing highway defects 2000, making the detection more accurate and reliable.

[0126] By acquiring disease parameters and determining whether diseases such as frost heave or thaw settlement have occurred in each tested area, the areas to be repaired are identified. This assessment mechanism helps to promptly detect and treat diseases, thereby enabling preventative repair measures to prevent further deterioration.

[0127] After identifying the area to be repaired, holes are drilled in the area, repair material is injected, and the injected area is leveled and compacted. This targeted repair method not only improves repair efficiency but also ensures repair quality and extends the service life of Highway 2000.

[0128] This method enables timely detection and treatment of road defects, significantly improving the safety and reliability of Highway 2000. This is of great significance for ensuring driving safety and reducing traffic accidents.

[0129] It should be noted that, where there is no conflict, the features in the embodiments of this disclosure can be combined with each other.
