Description

Technical Field

[0001] This invention relates to road maintenance technology, and more particularly to a road early warning method, an assembly of paving components and units. Background Technology

[0002] In the field of road maintenance, pavement damage (such as potholes, cracks, and subsidence) is the most common road defect. Its causes are complex and diverse, including long-term vehicle loads, temperature stress changes, rainwater infiltration and erosion, subgrade settlement, and construction quality defects. If these defects are not repaired promptly, they will not only reduce road smoothness and affect driving comfort, but may also pose a serious threat to traffic safety. For example, potholes can cause vehicles to bump, tire blowouts, or even lose control, while cracks, if not sealed in time, will accelerate water infiltration, further softening the subgrade and causing more serious structural damage, such as loosening of the base layer and pavement subsidence. Furthermore, the continued deterioration of damaged pavements will significantly increase the difficulty and cost of later repairs, and may even force premature major repairs or reconstruction of the road, resulting in a huge economic burden and waste of social resources.

[0003] Traditional road repair methods primarily rely on on-site mixing of materials such as hot-mix asphalt, cold-mix asphalt, or rapid-hardening concrete, and require supporting construction equipment (such as pavers, rollers, and cutters) and skilled technicians. However, this repair method has significant limitations:

[0004] 1. Slow response speed: It often takes a long time from the discovery of damage to the organization of personnel, equipment and materials to enter the site, especially in remote areas or busy traffic sections, making coordination difficult and delaying the opportunity for emergency repairs.

[0005] 2. High environmental dependence: Traditional asphalt repair usually requires dry and warm construction conditions, which are difficult to implement in severe weather such as rain, snow and low temperature. Cold patch material has relatively poor bonding strength and durability.

[0006] 3. Significant traffic disruption: Repair work often requires the closure of some lanes, affecting normal traffic flow, especially on urban main roads or highways, which can easily cause congestion and secondary accidents.

[0007] 4. High labor costs: Reliance on manual labor results in low efficiency, and the difficulty in allocating manpower during nighttime or emergency construction further slows down the repair progress.

[0008] Therefore, how to quickly repair damaged roads has become an urgent problem to be solved. Summary of the Invention

[0009] In view of the above problems, the present invention is proposed to provide a road warning method, paving assembly and unit that overcomes or at least partially solves the above problems.

[0012] Pressure data is collected at each detection point, and the effective data collected by pedestrians is obtained based on the data collection results.

[0013] The road condition of the damaged road is determined based on the effective collected values, and an early warning signal is sent to the management terminal when the road condition is a sunken state.

[0014] Optionally, in the method according to the present invention, pressure is collected at each detection point, and the effective collected value of the corresponding pedestrian trampling is obtained based on the collection results, including:

[0015] Pressure data is collected at each detection point, and the valid data collected by pedestrians based on the data collection results are obtained, including:

[0016] If the pressure acquisition value of any corresponding detection point is zero, the corresponding output duration is obtained, and if the output duration is less than the preset dwell time, the detection point is determined as the first point.

[0017] Other detection points corresponding to the same assembly and paving unit as the first point are respectively determined as second points, and the pressure acquisition value of each second point is determined based on the output duration;

[0018] When it is determined that the pressure sampling value output at any second point is in a state of numerical fluctuation during the output duration, the output duration is determined as the effective sampling value of the corresponding pedestrian stepping.

[0019] Optionally, in the method according to the invention, when it is determined that the pressure sampling value output at any second point during the output duration is in a state of numerical fluctuation, the output duration is determined as the effective sampling value corresponding to pedestrian trampling, including:

[0020] The output duration is divided into segments with the same time interval, and the pressure acquisition values ​​of each other detection point at each segment are determined.

[0021] The pressure data collected at each second point is compared pairwise based on the chronological order to obtain the differences between each pair of data points.

[0022] Obtain the difference ratio corresponding to a zero acquisition difference value, and if the difference ratio is less than or equal to a preset ratio, determine the output duration as the valid acquisition value of the pedestrian stepping that is related to the first point.

[0023] Optionally, in the method according to the invention, the method further includes:

[0024] The method further includes:

[0025] The response duration of the first point is a valid acquisition value. Each unit corner point located in other assembly and paving units that is adjacent to the unit corner point corresponding to the first point is determined, and the detection point corresponding to each unit corner point is determined as the third point.

[0026] Obtain the start time of the corresponding output duration, and determine the pressure acquisition value of each third point based on the start time;

[0027] If the pressure measurement value at any third point is zero, the corresponding output duration is obtained, and the output duration is determined as the valid measurement value of the pedestrian stepping that is related to the third point.

[0028] Optionally, in the method according to the present invention, determining the road condition corresponding to the damaged road based on the effective collected values ​​includes:

[0029] Obtain the effective quantity of all valid collected values ​​corresponding to the same assembly and paving unit, and configure the corresponding quantity weights based on the effective quantity to obtain the quantity evaluation value;

[0030] All valid collected values ​​corresponding to the same assembly and paving unit are summed, and the total collected value is compared with a preset interval table, wherein the preset interval table includes different numerical intervals.

[0031] Based on the numerical range in which the total collected value is located, a corresponding numerical weight is configured for the total collected value to obtain a numerical evaluation value;

[0032] The quantity evaluation value and the numerical evaluation value are summed to calculate the filling attribute of the corresponding assembly and paving unit based on the obtained total evaluation value.

[0033] The road condition of the corresponding damaged road is determined based on the filling attributes of each assembled paving unit.

[0034] Optionally, in the method according to the invention, the road condition corresponding to the damaged road is determined based on the filling properties of each assembled pavement unit, including...

[0035] Obtain the extension direction of the corresponding damaged road, and sort the assembly paving units that make up the assembly paving component from near to far based on the extension direction to obtain the unit sequence;

[0036] When it is determined that there is an assembly and paving unit with a safety attribute at each sequence position based on the unit sequence, the assembly and paving units with the corresponding safety attribute are connected based on the adjacency relationship along the extension direction to obtain the connection route.

[0037] In response to the connection route penetrating the damaged road in the extending direction, the road condition of the damaged road is determined to be flat, and conversely, it is determined to be concave.

[0038] According to another aspect of the present invention, an assembly paving component for use in the above-described road warning method is provided.

[0039] It is composed of multiple assembled and laid units;

[0040] The adjacent assembly and paving units are fixed together by detachable connecting components.

[0041] Optionally, in the components according to the invention, the detachable connection component includes:

[0043] A surface connecting plate extending from the middle of the upper support plate to the middle of the lower support plate;

[0048] Optionally, in the unit according to the present invention, the support frame includes a rectangular frame and a slot dividing component disposed in the rectangular frame, wherein the slot dividing component is used to divide the frame groove into a plurality of filling grooves arranged in an array.

[0049] According to the present invention, the assembled pavement unit and / or assembled pavement assembly provided by the present invention, through innovative modular structural design, can quickly and efficiently repair road surface damage, significantly improving the response speed and safety of road emergency maintenance. Specifically, the filling unit is composed of three parts working together: a filling platform, a support frame, and a load-bearing platform, and has the following significant advantages:

[0050] 1. Quick installation and stable support: The support frame is set around the filling platform to form a frame groove structure, which allows the filling unit to be accurately embedded into the damaged area of ​​the road surface, avoiding loosening or displacement due to size mismatch; while the load-bearing platform covers the support frame, which not only enhances the stability of the overall structure, but also distributes vehicle loads, preventing the filling unit from collapsing or deforming under pressure, and ensuring that the temporarily repaired road surface has sufficient load-bearing capacity.

[0057] Figure 3 A schematic diagram of the detachable connection component in this embodiment is shown;

[0058] Figure 4 A flowchart illustrating an installation method for an assembled pavement component according to another embodiment of the present invention is shown;

[0059] Figure 5 A flowchart of a road warning method according to yet another embodiment of the present invention is shown. Detailed Implementation

[0060] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0061] To address the problems existing in the prior art, the inventors proposed the solution of this invention. One embodiment of this invention provides an assembly and paving unit.

[0062] Figure 1 A schematic diagram of the structure of an assembly and paving unit according to an embodiment of the present invention is shown, as follows: Figure 1 As shown, the assembly and paving unit may include a filling platform, a support frame, and a load-bearing platform.

[0063] It can be explained that a filling platform can be understood as a tool used to fill in damaged roads. Figure 1 In the example, the filling platform can be specifically rectangular, and the corresponding support frame is set around the perimeter of the filling platform to form a corresponding frame groove. Here, corresponding decorations can be placed in the frame groove, such as clumps of grass, to increase the decorative effect and improve the greening effect. In order to cover the frame groove while allowing pedestrians to pass, the supporting platform can be further abutted against the support frame to complete the covering of the frame groove.

[0064] Furthermore, in this embodiment, in order to increase the structural strength of the corresponding assembly and paving unit, based on Figure 1 As can be seen from the content, the support frame can specifically include a rectangular frame and slot dividing components disposed within the rectangular frame. The slot dividing components are mainly used to divide the overall frame grooves to form multiple filling grooves arranged in an array. Figure 1 As can be seen from the figure, there are 9 corresponding filling grooves. However, in actual production, since different numbers of filling grooves can be set based on different application scenarios, this embodiment does not limit the specific number.

[0065] exist Figure 1In this context, the aforementioned slot division component may include at least one first support extending along a first direction and at least one second support extending along a second direction, wherein the first direction is perpendicular to the second direction, and the number of the first and second supports can be set based on actual needs. It is certain that the more first and second supports there are, the higher the corresponding structural strength should be.

[0066] For example, in this embodiment, based on the above, it is known that the corresponding frame groove can be divided into multiple filling grooves by the corresponding slot segmentation component. Therefore, in order to cover each filling groove individually, the corresponding support platform can be set to have the same number of support plates as the filling groove. Here, in order to ensure that each support plate can cover each filling groove, an inner extension edge extending parallel to the filling platform can be provided on the inner surface of the filling groove. Figure 1 (not shown in the image), thus the covering of the filling groove can be accomplished by abutting the bearing plate against the inner extension edge.

[0067] It should be noted that the inner edge of each filling groove should be understood as being set on the corresponding support frame.

[0068] Furthermore, in this embodiment, since each filling groove can hold corresponding turf blocks for decoration, in order to improve the survival rate of the turf blocks, corresponding permeable holes can be provided on the bottom surface of the filling platform, so that the turf blocks can absorb the corresponding water and nutrients from the soil through the permeable holes; in addition, in this embodiment, the corresponding support platform can also be set as a corresponding transparent structure, so as to ensure that the turf blocks can absorb the corresponding sunlight, and the transparent support platform can also allow the turf blocks to be displayed accordingly, thereby improving the corresponding decorative effect.

[0069] Figure 2 An assembly and installation component according to another embodiment of the present invention is shown, such as Figure 2 As shown, the assembly pavement component is composed of multiple assembly pavement units spliced ​​together, and the corresponding two assembly pavement units are fixed together by detachable connecting components.

[0070] It can be explained that when the area of ​​a damaged road that needs to be filled is large, multiple assembled paving units need to work together to fill it. In order to improve the overall filling effect, multiple assembled paving units can be fixed based on corresponding detachable connecting components, so as to fill the damaged road based on the formed whole.

[0071] like Figure 3 As shown, Figure 3The detachable connection assembly shown in this embodiment may include: an upper support plate, a lower support plate, and a corresponding surface connecting plate, wherein the upper support plate and the lower support plate are arranged in parallel, and the surface connecting plate extends from the middle of the upper support plate to the middle of the lower support plate.

[0072] It can be explained that, based on the above structure, the detachable connecting assembly has an upper support plate, a lower support plate, and a surface connecting plate that can form a first snap-fit ​​groove and a second snap-fit ​​groove. The first snap-fit ​​groove and the second snap-fit ​​groove can respectively snap-fit ​​two support frames in adjacent positions, thereby completing the splicing of the corresponding two assembly and paving units. Here, in this embodiment, the upper support plate, the lower support plate, and the surface connecting plate can be formed as a single piece, and can be made of stainless steel.

[0073] Furthermore, in order to improve the connection strength between the detachable connecting component and the support frame, in this embodiment, the corresponding upper support plate and lower support plate also include corresponding first bolt holes and second bolt holes, respectively. The corresponding support frame should also have corresponding frame bolt holes. When the detachable connecting component is snapped onto the corresponding support frame through the snap-fit ​​groove, the first bolt hole, the frame bolt hole and the second bolt hole can be passed through the fixing bolt in sequence to realize the bolt fixation between the support frame and the detachable connecting component.

[0074] In addition, based on Figure 3 As can be seen from the example, in this embodiment, the corresponding first bolt hole and second bolt hole may each include two, thereby increasing the corresponding fixing strength.

[0075] In summary, the assembled pavement unit and / or assembled pavement components provided by this invention, through innovative modular structural design, can quickly and efficiently repair pavement damage, significantly improving the response speed and safety of road emergency maintenance. Specifically, the filling unit is composed of three parts working together: a filling platform, a support frame, and a load-bearing platform, and has the following significant advantages:

[0076] 1. Quick installation and stable support: The support frame is set around the filling platform to form a frame groove structure, which allows the filling unit to be accurately embedded into the damaged area of ​​the road surface, avoiding loosening or displacement due to size mismatch; while the load-bearing platform covers the support frame, which not only enhances the stability of the overall structure, but also distributes vehicle loads, preventing the filling unit from collapsing or deforming under pressure, and ensuring that the temporarily repaired road surface has sufficient load-bearing capacity.

[0077] 2. Modular design with strong adaptability: This invention adopts a standardized and splicable modular design, which can be flexibly combined according to the size of potholes or cracks, and is suitable for road damage of different shapes and depths, significantly improving the adaptability of emergency repair.

[0078] 3. Durability and reusability: The filling platform and support frame can be easily removed and reused, reducing maintenance costs and conforming to the concept of green construction;

[0079] 4. Improved construction efficiency and safety: Compared with traditional repair processes, this filling unit does not require complicated equipment or long curing time. It can restore road traffic capacity simply by placing it, making it especially suitable for emergency repairs at night, in rainy or snowy weather, or on busy roads.

[0080] This invention achieves a comprehensive effect of rapid response, stable load-bearing, flexible adaptation and sustainable use through optimized structural design, providing an efficient and reliable solution for road emergency maintenance, with significant practical value and socio-economic benefits.

[0081] Another embodiment of the present invention provides a method for installing assembled pavement components. Figure 4 The flowchart of its method is shown, as follows: Figure 4 As shown, the method includes the following steps:

[0082] S101. Compact the soil on the damaged road surface;

[0083] S102. After confirming that the soil compaction is completed, fill the damaged road with the above-mentioned assembled paving components and compact them.

[0084] For example, in this embodiment, when filling damaged roads, the original soil can be compacted. After ensuring a compaction coefficient of 95%, the product can be laid directly. After compaction and leveling, it meets the road specification coefficients and can be safely used without maintenance. This method improves construction efficiency, reduces pollution, lowers costs, and reduces maintenance costs.

[0085] Furthermore, it can be explained that during the process of filling damaged roads based on the assembled pavement components, a 2-3cm misalignment can be set between the corresponding filler and the supporting frame. This allows the assembled pavement components to form a certain interlocking relationship with the soil, increasing friction and enhancing stability to prevent displacement. Sensors can also be installed on the filling platform to detect the interlocking force and collect data, preventing the risk of frame damage due to uneven stress.

[0086] Another embodiment of the present invention provides a road warning method, wherein the method can be implemented based on a computing device, which can be understood as a terminal with data processing capabilities, such as a computer.

[0087] like Figure 5As shown, the method begins with step S201, wherein step S201 includes the following:

[0088] In response to the completion of the pavement assembly to fill the damaged road, corner connection lines are established between the corner points of each unit corresponding to the same pavement unit and the center point of the unit, and detection points are determined at a preset distance from each unit corner point along each corner connection line.

[0089] For example, in this embodiment, when a section of road is damaged, the required number of assembled pavement units can be determined based on the size of the area to be filled. The assembled pavement units of the corresponding number of units can be connected based on the corresponding detachable connecting components. The damaged road can then be filled based on the obtained assembled pavement components, thereby achieving emergency treatment of the damaged road and facilitating normal pedestrian passage.

[0090] It can be explained that after the damaged road is filled based on the assembled pavement components, pedestrians can walk on the assembled pavement components to cross the damaged road. However, after long-term use, the soil of the damaged road may collapse, resulting in corresponding depressions in the damaged road. This may cause the assembled pavement unit to tilt when a pedestrian walks on it. The greater the tilt, the greater the depression in the corresponding area. If the situation is dangerous (i.e., the depression is too deep), it means that the damaged road is no longer suitable for pedestrians. In this case, it is necessary to notify the relevant personnel to carry out routine maintenance on the damaged road.

[0091] Furthermore, in order to determine the degree of tilt, a corresponding pressure sensor can be set for each assembly and paving unit, and the corresponding setting position can be determined based on the detection point in step S102 above.

[0092] That is, in this embodiment, in order to determine whether each assembly paving unit tilts when walked on by pedestrians, the tilt can be determined by setting up a corresponding pressure sensor. When setting up the pressure sensor, corner connection lines between the corner points of each unit and the center point of the same assembly paving unit can be established in advance, and detection points at a preset distance from the corner points of the units can be determined along each corner connection line to ensure that the obtained detection points have a certain installation area for the installation of pressure sensors.

[0093] It can be explained that a unit corner point can be understood as the corner point of the unit outline of the corresponding paving unit. For example, in this embodiment, the paving unit is rectangular, so the corresponding unit corner point should include four. After the installation of the corresponding pressure sensor is completed, when any pedestrian steps on any detection corner point, when the road area corresponding to the detection corner point is depressed, the corresponding paving unit will be tilted. At this time, the pressure sensor at another detection point may output a pressure acquisition value of zero due to tilting. Moreover, the greater the degree of depression, the greater the corresponding degree of tilt should be, which will result in a longer duration of zero pressure acquisition value at the corresponding detection point. Therefore, the pressure acquisition value output by the pressure sensor at each detection point can be used to help determine whether there is a corresponding depression area in the damaged road.

[0094] Step S202 includes the following:

[0095] Pressure data is collected at each detection point, and the effective data collected by pedestrians is obtained based on the data collection results.

[0096] For example, in this embodiment, when setting up the corresponding pressure sensor based on the above content, pressure can be collected at each detection point to determine whether a corresponding depression area exists based on the output pressure collection value. As mentioned above, the greater the degree of depression in the depression area, the longer the duration of the zero pressure collection value at the corresponding detection point should be. Therefore, in order to improve the accuracy of the determination, it is necessary to determine whether the cause of each zero pressure collection value is based on the walking and trampling of pedestrians, so as to determine whether it is a valid or invalid collection value. For example, in one case, when a pedestrian stands still on a certain assembly paving unit with a corresponding depression area for a long time, the duration of the zero pressure collection value obtained is the corresponding invalid collection value.

[0097] Furthermore, in this embodiment, the aforementioned "collecting pressure data at each detection point and obtaining the corresponding effective data collection value based on the data collection results" may also include the following steps:

[0098] If the pressure acquisition value of any corresponding detection point is zero, the corresponding output duration is obtained, and if the output duration is less than the preset dwell time, the detection point is determined as the first point.

[0099] Other detection points corresponding to the same assembly and paving unit as the first point are respectively determined as second points, and the pressure acquisition value of each second point is determined based on the output duration;

[0100] When it is determined that the pressure sampling value output at any second point is in a state of numerical fluctuation during the output duration, the output duration is determined as the effective sampling value of the corresponding pedestrian stepping.

[0101] For example, in this embodiment, obtaining the corresponding valid collected value can be achieved based on the following method steps:

[0102] First, when the pressure acquisition value at any detection point is zero, it may mean that the assembly and paving unit corresponding to that detection point may have been stepped on, and there is a corresponding indentation area. It can be explained that when the cause of the corresponding pressure acquisition being zero is due to pedestrians walking and stepping on it, the corresponding output duration should last for a shorter time. When the cause is due to pedestrians standing still, the corresponding output duration should last for a longer time. Therefore, by comparing the obtained output duration with the preset dwell time, and if the output duration is less than the preset dwell time, the detection point is determined as the first point to complete the corresponding initial screening process.

[0103] Then, since the detection points within the same assembly and paving unit are interconnected, if the cause is based on pedestrians walking and trampling, the other detection points in the surrounding area should also be affected by the corresponding fluctuations. However, if the cause is based on pedestrians standing still, the other detection points in the surrounding area should not be affected by the corresponding fluctuations or should have very little fluctuation. Therefore, in order to further determine whether the cause is based on pedestrians walking and trampling, all other detection points in the same assembly and paving unit corresponding to the first point can be designated as second points, and the pressure acquisition value output by each second point during the output duration can be determined.

[0104] Finally, when it is determined that the pressure sampling value output by any second point during the output duration exhibits a corresponding numerical fluctuation, it can be determined that the zero pressure sampling value output by the first point during the output duration is due to the pedestrian walking and stepping on the ground. Therefore, the corresponding output duration can be determined as the effective sampling value of the corresponding pedestrian stepping.

[0105] It should be noted that the above numerical fluctuations may be understood as the pressure acquisition value output by the second point during the output duration exhibiting a fluctuating pattern, i.e., a high frequency of change.

[0106] Furthermore, in this embodiment, the aforementioned "when it is determined that the pressure sampling value output at any second point during the output duration is in a state of numerical fluctuation, the output duration is determined as the effective sampling value corresponding to pedestrian trampling" may also include the following steps:

[0107] The duration is divided into segments with the same time interval, and the pressure values ​​output by each other detection point at each segment are determined.

[0108] The pressure data collected at each second point is compared pairwise based on the chronological order to obtain the differences between each pair of data points.

[0109] Obtain the difference ratio corresponding to a zero acquisition difference value, and if the difference ratio is less than or equal to a preset ratio, determine the output duration as the valid acquisition value of the pedestrian stepping that is related to the first point.

[0110] For example, in this embodiment, determining whether the output duration is a valid acquisition value can be achieved based on the following method steps:

[0111] First, the output duration can be divided into segments with the same time interval, allowing for more precise analysis of the pressure data through this fine-grained time division.

[0112] Then, the pressure values ​​collected at each second point are calculated in chronological order to obtain the differences between each pair of values. Based on these differences, the pressure change trend over time can be clearly presented to quickly understand the pressure fluctuations.

[0113] Finally, the zero values ​​in each acquisition difference can be counted, and the ratio of the obtained statistical quantity to the total number of differences for each acquisition difference can be calculated to obtain the corresponding difference ratio. When the difference ratio is less than or equal to a preset ratio, the output duration can be determined as the valid acquisition value of the pedestrian stepping that is related to the first point. It can be explained that when any acquisition difference is zero, it indicates that the second point has no corresponding fluctuation between two adjacent time intervals; when the corresponding difference ratio is large (i.e., greater than the preset ratio), it indicates that the fluctuation degree of the second point is small within the output duration. Therefore, the reason for the zero pressure output value of the corresponding first point can be determined as the pedestrian standing still. Similarly, when the corresponding difference ratio is small (i.e., less than the preset ratio), it indicates that the fluctuation degree of the second point is large within the output duration. Therefore, the reason for the zero pressure output value of the corresponding first point can be determined as the pedestrian walking and stepping.

[0114] Furthermore, based on the above, in this embodiment, the corresponding pavement assembly can be assembled from multiple pavement units. It can be explained that since the pavement assembly is composed of multiple pavement units, when a pedestrian steps on a pavement unit causing it to tilt, if other pavement units also have corresponding depressions in their corresponding road areas, these other pavement units may be affected and tilt as well. Therefore, based on this propagation characteristic, it can be determined whether other pavement units also have corresponding depressions. The specific method steps are as follows:

[0115] The response duration of the first point is a valid acquisition value. Each unit corner point located in other assembly and paving units that is adjacent to the unit corner point corresponding to the first point is determined, and the detection point corresponding to each unit corner point is determined as the third point.

[0116] Obtain the start time of the corresponding output duration, and determine the pressure acquisition value of each third point based on the start time;

[0117] If the pressure measurement value at any third point is zero, the corresponding output duration is obtained, and the output duration is determined as the valid measurement value of the pedestrian stepping that is related to the third point.

[0118] For example, in this embodiment, the acquisition of effective data points for the detection points corresponding to other assembled paving components based on the corresponding splicing relationships can be specifically implemented in the following ways:

[0119] First, based on the assembled paving components, each unit corner point that is adjacent to the unit corner point of the corresponding first point and is located in a different assembled paving unit can be determined, and each determined unit corner point can be further determined as a third point.

[0120] Then, the start time of the corresponding output duration is obtained, and based on the start time, the pressure acquisition value of each third point is determined. By using the start time as a time anchor, the collected pressure data can be ensured to have time synchronization.

[0121] Finally, if the pressure acquisition value at any third point is zero, it indicates that there is also a corresponding depression area in the road area of ​​the paved unit corresponding to the third point. In this case, the output duration of the corresponding third point can be determined as its effective acquisition value.

[0122] Step S203 includes the following:

[0123] The road condition of the damaged road is determined based on the effective collected values, and an early warning signal is sent to the management terminal when the road condition is a sunken state.

[0124] For example, in this embodiment, based on the above, it is known that the longer the corresponding output duration, the greater the degree of depression should be. Therefore, after obtaining the corresponding valid acquisition value, the road condition of the damaged road can be further determined based on the valid acquisition value; and when the road condition is determined to be a depression state, a corresponding early warning signal is sent to the management terminal to remind the management terminal to carry out routine repairs on the damaged road in a timely manner.

[0125] Furthermore, in this embodiment, the aforementioned "determining the road condition corresponding to the damaged road based on valid collected values" may further include the following steps:

[0126] Obtain the effective quantity of all valid collected values ​​corresponding to the same assembly and paving unit, and configure the corresponding quantity weights based on the effective quantity to obtain the quantity evaluation value;

[0127] All valid collected values ​​corresponding to the same assembly and paving unit are summed, and the total collected value is compared with a preset interval table, wherein the preset interval table includes different numerical intervals.

[0128] Based on the numerical range in which the total collected value is located, a corresponding numerical weight is configured for the total collected value to obtain a numerical evaluation value;

[0129] The quantity evaluation value and the numerical evaluation value are summed to calculate the filling attribute of the corresponding assembly and paving unit based on the obtained total evaluation value.

[0130] The road condition of the corresponding damaged road is determined based on the filling attributes of each assembled paving unit.

[0131] For example, in this embodiment, after obtaining the effective data collection values ​​of the corresponding paving unit, the road condition of the corresponding damaged road can be further determined based on the following method steps:

[0132] First, after acquiring the pressure data at each detection point corresponding to the same pavement unit, in order to comprehensively evaluate the road area corresponding to the pavement unit, the effective quantity can be obtained based on all the effective data collected for that pavement unit. Then, a weighting configuration can be applied based on the effective quantity. It is known that a larger effective quantity indicates more detection points with zero output pressure data for that pavement unit, meaning the degree of depression in the corresponding depression area should be greater. Therefore, by configuring different weightings for the quantities, a reasonable evaluation based on the quantity dimension can be performed. For example, when the effective quantity is 4, the corresponding weighting can be 0.6, while when the effective quantity is 3, the corresponding weighting can be 0.4. By configuring the effective quantity and its corresponding weighting, a quantity evaluation value for the corresponding quantity dimension can be obtained.

[0133] Then, after completing the evaluation of the quantitative dimension, a reasonable assessment can also be made based on the numerical dimension. That is, all valid collected values ​​corresponding to the same pavement unit are summed and the total collected value is compared with the preset interval table. The preset interval table includes different numerical intervals. The summation of valid collected values ​​can obtain the comprehensive data index of the numerical dimension corresponding to the pavement unit. The preset interval table is an evaluation reference formulated based on road maintenance experience and standards. For example, the preset interval table may stipulate that the total collected value in a certain interval represents that the road damage is relatively minor, and in another interval represents that the damage is relatively severe. By comparing the total collected value with the preset interval table, the degree and range of road damage can be preliminarily determined.

[0134] Next, based on the numerical range in which the total collected value falls, a corresponding numerical weight is configured for the total collected value to obtain a numerical evaluation value. Here, different numerical ranges reflect different road damage conditions. By configuring corresponding numerical weights for each range, the degree of road damage represented by the total collected value can be measured more accurately. For example, the total collected value in the severely damaged range has a higher numerical weight and a higher corresponding numerical evaluation value. This further refines the assessment of road conditions and makes the assessment results more accurate.

[0135] Subsequently, the quantity evaluation value and numerical evaluation value of the same assembly paving unit obtained above are summed and calculated. The filling attribute of the corresponding assembly paving unit is determined based on the obtained total evaluation value. That is, based on the comprehensive consideration of quantity evaluation value and numerical evaluation value, a comprehensive evaluation can be carried out based on both quantity and numerical dimensions. The filling attribute is determined by the total evaluation value. Here, the filling attribute can include hazard attribute and safety attribute. Specifically, it can be determined based on the evaluation result between the total evaluation value and the retrieved preset evaluation value. For example, when the total evaluation value is greater than the preset evaluation value, the corresponding filling attribute can be a hazard attribute, and when the total evaluation value is less than or equal to the preset evaluation value, the corresponding filling attribute can be a safety attribute. It should be noted that the assembly paving unit corresponding to the hazard attribute can be understood as not recommended for pedestrians to walk on, while the assembly paving unit corresponding to the safety attribute can be understood as being built for pedestrians to walk on.

[0136] Finally, after determining the filling attributes of each assembly pavement unit, the filling attributes of each assembly pavement unit that makes up the assembly pavement component can be summarized and analyzed to determine the road condition of the corresponding damaged road. In the subsequent process, based on the road condition, it can be determined whether to send the corresponding early warning signal to the management end to inform the management end to carry out routine repairs on the damaged road in a timely manner and ensure the safety and smooth flow of the road.

[0137] Furthermore, in this embodiment, the aforementioned "determining the road condition of the corresponding damaged road based on the filling attributes of each assembled paving unit" may further include the following steps:

[0138] Obtain the extension direction of the corresponding damaged road, and sort the assembly paving units that make up the assembly paving component from near to far based on the extension direction to obtain the unit sequence;

[0139] When it is determined that there is an assembly and paving unit with a safety attribute at each sequence position based on the unit sequence, the assembly and paving units with the corresponding safety attribute are connected based on the adjacency relationship along the extension direction to obtain the connection route.

[0140] In response to the connection route penetrating the damaged road in the extending direction, the road condition of the damaged road is determined to be flat, and conversely, it is determined to be concave.

[0141] For example, in this embodiment, after completing the filling properties of each assembly pavement unit that makes up the assembly pavement component, the road condition of the corresponding damaged road can be determined based on the following method steps:

[0142] First, based on real-world scenarios, the road segments where the damaged roads are located generally have a corresponding extension direction, that is, the direction of travel of the road segment. Therefore, by obtaining the extension direction of the corresponding damaged roads, the assembly pavement units that make up the assembly pavement components can be sorted from near to far to obtain the corresponding unit sequence.

[0143] Next, it can be explained that since the number of assembly pavement units included in the assembly pavement component in this embodiment is determined based on the size of the area to be filled in the corresponding damaged road, when the area size is large, there may be multiple assembly pavement units corresponding to the same sequence position. Based on this, the filling attribute of each assembly pavement unit located in the same sequence position can be determined according to the unit sequence. When the filling attribute of all assembly pavement units corresponding to the same sequence position is a dangerous attribute, it indicates that the current damaged road is impassable. At this time, the road state of the damaged road needs to be determined as a concave state. Similarly, when it is determined based on the unit sequence that there is an assembly pavement unit with a corresponding filling attribute of safety at each sequence position, the assembly pavement units with the corresponding safety attribute can be connected along the extension direction based on the adjacency relationship to obtain the corresponding connection route.

[0144] Finally, when the obtained connecting route can penetrate the damaged road in the extension direction, it indicates that the current damaged road can still be passed by pedestrians normally. Therefore, the road condition corresponding to the damaged road can be determined as a flat state, and vice versa.

[0145] In summary, according to the method of this embodiment, firstly, regarding the timeliness of road maintenance, when damaged roads are detected, the assembled pavement components respond quickly to fill the gaps, repairing the damaged parts of the road immediately to facilitate pedestrian passage, reducing road maintenance costs and extending the overall service life of the road; secondly, regarding the accuracy of road condition monitoring, by establishing corner connection lines between the corner points and center points of the assembled pavement units and determining the detection points along these lines, a scientific and uniform layout for pressure data acquisition is provided. This layout can comprehensively cover the damaged roads and obtain more representative pressure data. Furthermore, by collecting pressure data at each detection point and obtaining the corresponding effective data collected from pedestrian treading based on the data collection results, subtle changes in the road surface can be keenly detected, as the force and frequency of pedestrian treading are significant. The rate is relatively stable. By analyzing these effective collected values, the actual condition of the road can be accurately judged, especially whether there are potential dangers such as road depressions. Compared with the traditional manual inspection method, this method is more efficient and accurate, and will not miss minor road defects. Finally, in terms of the timeliness and effectiveness of safety warnings, the road condition is determined based on the effective collected values, and warning signals are sent to the management end in a timely manner when the road condition is depressed. This greatly improves the road safety guarantee capability. After receiving the warning signal, the management end can quickly arrange professional personnel to deal with it, such as repairing the depressed area and setting up warning signs, so as to avoid safety accidents such as pedestrians falling and getting injured due to road depressions. At the same time, this also helps the road management department to establish a complete road safety file and make more scientific plans and decisions for road maintenance and management.
