Description

Technical Field

[0001] The present invention relates to road maintenance technology, and in particular to a road early warning method, an assembly paving component and a unit. Background Art

[0002] In the field of road maintenance, pavement damage (such as potholes, cracks, and collapses) is the most common problem. Its causes are complex and diverse, including long-term vehicle loads, temperature stress fluctuations, rainwater infiltration and erosion, roadbed settlement, and construction quality defects. If these damages are not repaired promptly, they will not only reduce road smoothness and affect driving comfort, but also pose a serious threat to traffic safety. For example, potholes can cause vehicles to jolt, tire blowouts, and even loss of control. If cracks are not promptly sealed, they will accelerate water infiltration, further softening the roadbed and causing more serious structural damage such as loose base and road surface subsidence. In addition, the continued deterioration of damaged pavement will significantly increase the difficulty and cost of subsequent repairs, and may even force premature overhaul or reconstruction of roads, resulting in a huge economic burden and waste of social resources.

[0003] Traditional road repair methods rely primarily on on-site mixing of hot-mix asphalt, cold patch materials, or rapid-hardening concrete, and require supporting construction equipment (such as pavers, rollers, cutters, etc.) and skilled technicians to operate. However, this repair method has obvious limitations: 1. Slow response: It often takes a long time from the discovery of damage to the organization of personnel, equipment, and materials to the site. Especially in remote areas or on busy roads, coordination is difficult, which delays the opportunity for emergency repairs.

[0004] 2. High environmental dependence: Traditional asphalt repairs usually require dry and warm construction conditions, which are difficult to implement in severe weather such as rain, snow, and low temperatures. The bonding strength and durability of cold patch materials are relatively poor.

[0005] 3. Large traffic disruption: The repair process often requires the closure of some lanes, affecting normal traffic, especially on urban main roads or highways, which can easily cause congestion and secondary accidents.

[0006] 4. High labor costs: Relying on manual labor, the efficiency is low, and manpower deployment is difficult at night or during emergency construction, further slowing down the repair progress.

[0007] Therefore, how to quickly repair damaged roads has become an urgent problem that needs to be solved. Summary of the Invention

DETAILED DESCRIPTION

[0022] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0023] To solve the above problems in the prior art, the inventors propose the solution of the present invention. One embodiment of the present invention provides an assembly paving unit.

[0024] Figure 1 FIG. 1 shows a schematic structural diagram of an assembly and paving unit according to an embodiment of the present invention. Figure 1 As shown, the assembly paving unit may include a filling platform, a support frame and a load-bearing platform.

[0025] It can be explained that the filling platform can be understood as being used to fill damaged roads. Figure 1In the example, the filling platform can be specifically rectangular, and the corresponding supporting frame is arranged around the platform periphery of the filling platform, so as to form a corresponding frame groove; here, corresponding decorations can be placed in the frame groove, for example, block lawns can be placed in the frame groove to increase the corresponding decorative effect and also improve a certain greening effect; and in order to achieve the shielding of the frame groove while allowing pedestrians to pass, the supporting platform can be further abutted against the supporting frame to complete the covering of the frame groove.

[0026] Furthermore, in this embodiment, in order to increase the structural strength of the corresponding assembly paving unit, based on Figure 1 As can be seen from the content, the support frame can specifically include a rectangular frame and a slot dividing component provided in the rectangular frame, wherein the slot dividing component is mainly used to divide the overall frame groove to form a plurality of filling grooves arranged in an array. Figure 1 In the figure, it can be seen that the number of corresponding filling grooves is 9. In the actual production process, since different numbers of filling grooves can be set based on different application scenarios, this embodiment does not limit the specific number.

[0027] exist Figure 1 In the above-mentioned slot dividing component, the at least one first pillar extending along the first direction and the at least one second pillar extending along the second direction, wherein the first direction is perpendicular to the second direction, and the number of the corresponding first pillars and the second pillars can be set based on actual needs. It can be determined that the greater the number of the first pillars and the second pillars, the higher the corresponding structural strength should be.

[0028] For example, in this embodiment, based on the above content, it can be known that the corresponding frame groove can be divided into a plurality of filling grooves by the corresponding slot dividing assembly. Therefore, in order to cover each filling groove separately, the corresponding supporting platform can be set to have the same number of supporting plates as the filling grooves. Here, in order to ensure that each supporting plate can cover each filling groove, an inner extension edge ( Figure 1 (not shown), the filling groove can be covered by placing the supporting plate body against the inner extension edge.

[0029] It can be explained that the inner extension of each filling groove should be understood to be provided on the corresponding supporting frame.

[0030] Furthermore, in this embodiment, since a corresponding block of lawn can be placed in each filling groove for decoration, in order to improve the survival rate of the block of lawn, corresponding water holes can be set on the bottom surface of the filling platform, so that the block of lawn can absorb corresponding water and nutrients from the soil based on the water holes; in addition, in this embodiment, the corresponding supporting platform can also be set as a corresponding transparent structure, so as to ensure that the block of lawn can absorb the corresponding sunlight, and the transparent structure of the supporting platform can also enable the block of lawn to be displayed accordingly to improve the corresponding decorative effect.

[0031] Figure 2 Shown is an assembly paving assembly according to another embodiment of the present invention, such as Figure 2 As shown, the assembly pavement component is spliced together by multiple assembly pavement units, and the corresponding two assembly pavement units are fixed through a detachable connecting component.

[0032] It can be explained that when the area of a damaged road that needs to be filled is large, multiple assembly paving units are required to fill it in a coordinated manner. In order to improve the overall filling effect, multiple assembly paving units can be fixed based on corresponding detachable connection components to fill the damaged road based on the formed whole.

[0033] like Figure 3 As shown, Figure 3 It is shown that the detachable connection assembly in this embodiment may include: an upper support plate, a lower support plate and a corresponding surface connection plate, wherein the upper support plate and the lower support plate are arranged in parallel, and the surface connection plate extends from the middle of the board surface of the upper support plate to the middle of the board surface of the lower support plate.

[0034] It can be explained that the detachable connection assembly obtained based on the above structure, its corresponding upper support plate, lower support plate and surface connection plate can form corresponding first clamping grooves and second clamping grooves, wherein the first clamping groove and the second clamping groove can respectively clamp the two support frames in adjacent positions, thereby completing the splicing of the corresponding two assembly paving units; here, the upper support plate, lower support plate and surface connection plate in this embodiment can be formed as one piece, and can be made of stainless steel.

[0035] Furthermore, in order to improve the connection strength between the detachable connecting assembly and the support frame, in this embodiment, the corresponding upper support plate and the lower support plate also include corresponding first bolt holes and second bolt holes, respectively, wherein the corresponding support frame should also have corresponding frame bolt holes. When the detachable connecting assembly is clamped on the corresponding support frame through the clamping groove, the first bolt hole, the frame bolt hole and the second bolt hole can be further penetrated in sequence by fixing bolts to achieve bolt fixation between the support frame and the detachable connecting assembly.

[0036] In addition, based on Figure 3 As can be seen from the example, in this embodiment, two corresponding first bolt holes and two corresponding second bolt holes may be included, thereby increasing the corresponding fixing strength.

[0037] In summary, the assembled pavement unit and / or assembled pavement assembly provided by the present invention, through its innovative modular structural design, can quickly and efficiently repair road damage, significantly improving the response speed and safety of emergency road maintenance. Specifically, the filling unit is composed of three parts: a filling platform, a support frame, and a load-bearing platform, and has the following significant advantages: 1. Quick installation and stable support: The support frame is set around the filling platform to form a frame groove structure, allowing the filling unit to be accurately embedded in the damaged area of the road surface to avoid loosening or displacement due to size mismatch. The load-bearing platform covers the support frame, which not only enhances the stability of the overall structure but also disperses the vehicle load, preventing the filling unit from collapsing or deforming under pressure, ensuring that the road surface after temporary repair has sufficient load-bearing capacity. 2. Modular design and strong adaptability: The present invention adopts a standardized and splicable modular design, which can be flexibly combined and used according to the size of potholes or cracks. It is suitable for road damage of different shapes and depths, significantly improving the adaptability of emergency repairs; 3. Durability and reusability: The filling platform and support frame can be easily removed and reused, reducing maintenance costs and complying with the concept of green construction; 4. Improve construction efficiency and safety: Compared with traditional repair processes, this filling unit does not require complex equipment or long curing time. It can restore road traffic capacity by simply placing it. It is especially suitable for emergency repairs at night, in rainy and snowy weather, or on busy roads.

[0038] The present invention achieves the comprehensive effects of rapid response, stable load-bearing, flexible adaptation and sustainable use by optimizing structural design, providing an efficient and reliable solution for road emergency maintenance, with significant practical value and socio-economic benefits.

[0039] Another embodiment of the present invention provides a method for installing a pavement assembly. Figure 4The method flow chart is shown as follows: Figure 4 As shown, the method includes the following steps: S101. Compact the soil of damaged roads; S102: Determine that the soil compaction is completed, fill the damaged road with the above-mentioned assembled paving components, and compact the soil.

[0040] For example, in this embodiment, when filling damaged roads, the original soil can be compacted. Once the compaction coefficient reaches 95%, the product can be directly laid. After compaction and leveling, the surface meets the road standard index coefficient, making it safe and practical without maintenance. This method improves construction efficiency, reduces pollution, and lowers construction and maintenance costs.

[0041] Furthermore, it can be explained that in the process of filling damaged roads based on assembled paving components, the corresponding filler and the supporting frame can be set to have a 2-3 cm offset, so that a certain bite relationship can be formed between the assembled paving components and the soil, increasing its friction, and also enhancing its stable state and not easy to shift; here, sensors can also be set on the filling platform to detect its bite force and collect data to prevent the risk of damage to the frame due to uneven force.

[0042] Yet another embodiment of the present invention provides a road warning method, wherein the method can be implemented based on a computing device, and the computing device can be understood as a terminal with data processing capabilities, such as a computer.

[0043] like Figure 5 As shown, the method starts at step S201, wherein step 201 includes the following contents: In response to the assembly paving component completing the filling of the damaged road, a corner point connecting line is established between each unit corner point of the same assembly paving unit and the unit center point, and a detection point position at a preset distance from each unit corner point is determined along each corner point connecting line; For example, in this embodiment, when a corresponding damaged road appears in a certain road section, the number of assembly paving units required can be determined based on the size of the area that needs to be filled in the damaged road, and the corresponding number of assembly paving units can be connected based on the corresponding detachable connecting components to fill the damaged road based on the obtained assembly paving components, thereby realizing emergency treatment of the damaged road and facilitating normal passage of pedestrians.

[0044] It can be explained that after the damaged road is filled based on the assembled pavement components, pedestrians can pass through the damaged road by stepping on the assembled pavement components. After long-term use, the soil on the damaged road may collapse, resulting in corresponding sunken areas in the damaged road. This will cause the assembled pavement unit to tilt as a whole when pedestrians step on it. The greater the corresponding tilt, the greater the degree of depression in the corresponding depression area. If the situation is more dangerous (that is, the depression is too deep), it means that the damaged road is no longer suitable for pedestrians to pass. At this time, it is necessary to notify the relevant staff to carry out routine processing of the integrity of the damaged road.

[0045] Furthermore, in order to determine the degree of inclination, a corresponding pressure sensor may be provided for each assembly and paving unit, and the corresponding setting position may be determined based on the detection point position in the above step S102.

[0046] That is, in this embodiment, in order to determine whether each assembly paving unit is tilted when pedestrians walk on it, the tilt can be determined by setting a corresponding pressure sensor. When setting the pressure sensor, a corner point connecting line between each unit corner point and the unit center point corresponding to the same assembly paving unit can be established in advance, and a detection point position with a preset distance from the unit corner point can be determined along each corner point connecting line to ensure that the obtained detection point position can have a certain installation area for the installation of the pressure sensor.

[0047] It can be explained that the unit corner point can be understood as the corner point of the unit outline of the corresponding assembly paving unit. For example, in this embodiment, the assembly paving unit is a rectangle, so the corresponding unit corner points 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 concave, the corresponding assembly paving unit will be in a tilted state. At this time, the pressure sensor of a corresponding other detection point may output a pressure collection value of zero due to the tilt, and the greater the degree of concave, the corresponding degree of tilt should also be greater, resulting in the duration of the corresponding output pressure collection value of zero at the detection point should be longer. Therefore, the pressure collection value output by the pressure sensor at each detection point can be used to assist in determining whether there is a corresponding concave area on the damaged road.

[0048] In step S202, the following contents are included: Pressure is collected at each detection point, and the effective collection value of the corresponding pedestrian stepping is obtained based on the collection results.

[0049] For example, in this embodiment, when the setting of the corresponding pressure sensor is completed based on the above content, corresponding pressure collection can be performed on each detection point respectively to determine whether there is a corresponding recessed area based on the output pressure collection value. Based on the above content, it can be seen that the greater the degree of recessed area, the longer the duration of the pressure collection value output by the corresponding detection point is zero. Therefore, in order to improve the corresponding determination accuracy, it is necessary to determine whether the reason for the pressure collection value to be zero each time is based on the walking and stepping of pedestrians to determine whether it is a valid collection value or an invalid collection value; for example, in one case, when a pedestrian stands still for a long time on an assembly pavement unit corresponding to a recessed area, the duration of the corresponding pressure collection value of zero is a corresponding invalid collection value.

[0050] Furthermore, in this embodiment, the above-mentioned "collecting pressure at each detection point and obtaining a valid collected value corresponding to the pedestrian stepping based on the collected result" may also include the following steps: In response to the pressure collection value corresponding to any detection point being zero, obtaining the corresponding output duration, and determining the detection point as the first point if the output duration is less than a preset dwell time; Determine other detection points corresponding to the same assembly and paving unit as the first point as second points, and determine a pressure collection value outputted by each second point based on the output duration; When it is determined that the pressure collection value outputted by any second point within the output duration is in a numerical fluctuation state, the output duration is determined as a valid collection value corresponding to the pedestrian stepping.

[0051] For example, in this embodiment, obtaining the corresponding valid collection value can be achieved based on the following method steps: First, when the pressure collection value of any detection point is zero, it may mean that the assembly paving unit corresponding to the detection point may be stepped on, and there is a corresponding sunken area. It can be explained that when the corresponding pressure collection is zero due to pedestrians walking and stepping on it, the corresponding output duration should last for a shorter time, and when the cause is based on pedestrians standing still, the corresponding output duration should last for a longer time. Therefore, the obtained output duration can be compared with the retrieved preset residence time, and when the output duration is less than the preset residence time, the detection point can be determined as the first point to complete the corresponding initial screening process; Then, since the detection points within the same assembly and paving unit are interrelated, when the cause is based on pedestrians walking and stepping on them, the corresponding other surrounding detection points should also be affected by the corresponding fluctuations, and when the cause is based on pedestrians standing still, the corresponding other surrounding detection points should not have the corresponding fluctuations or have very small fluctuations; therefore, in order to further determine whether the corresponding cause is based on pedestrians walking and stepping on them, all other detection points of the same assembly and paving unit corresponding to the first point can be determined as second points, and the pressure collection value output by each second point within the output duration can be determined; Finally, when it is determined that the pressure collection value outputted by any second point during the output duration presents a corresponding numerical fluctuation state, it can be determined that the pressure collection value outputted by the first point during the output duration is zero and is generated based on pedestrians walking and stepping on it. Therefore, the corresponding output duration can be determined as the effective collection value corresponding to pedestrian stepping on it.

[0052] It should be noted that the above-mentioned numerical fluctuation state may be understood as the pressure acquisition value outputted by the second point during the output duration having an ups and downs variation pattern, ie having a high frequency of variation.

[0053] Furthermore, in this embodiment, the above-mentioned "when determining that the pressure collected value outputted by any second point within the output duration is in a numerical fluctuation state, determining the output duration as a valid collected value corresponding to pedestrian stepping" may further include the following steps: Dividing the duration to obtain divided moments with the same time interval, and determining each pressure acquisition value outputted by each other detection point at each divided moment; Calculate the difference between each pressure collection value at each second point based on the time sequence to obtain each collection difference value; Obtain a difference ratio corresponding to a zero collected difference, and when the difference ratio is less than or equal to a preset ratio, determine the output duration as a valid collected value corresponding to the pedestrian stepping and associated with the first point.

[0054] For example, in this embodiment, determining whether the output duration is a valid acquisition value can be implemented based on the following method steps: First, the output duration can be divided to obtain each divided moment with the same time interval. Through this fine time division, the pressure data can be analyzed more accurately. Then, the pressure collection values at each second point are calculated in chronological order to obtain the difference between each other, so as to clearly present the pressure change trend over time based on the obtained difference, so as to quickly understand the pressure fluctuation situation; Finally, among the collected differences, those corresponding to zero can be counted, and the obtained count can be compared with the total number of differences corresponding to each collected difference value to obtain a corresponding difference ratio. When the difference ratio is less than or equal to a preset ratio, the output duration can be determined as a valid collected value associated with the first point and corresponding to pedestrian stepping. It can be explained that when any collected difference value is zero, it indicates that no corresponding fluctuation occurred at the second point between two adjacent divided moments. When the corresponding difference ratio is large (i.e., greater than the preset ratio), it indicates that the fluctuation degree corresponding to the second point during the output duration is small. Therefore, the cause of the zero pressure output value corresponding to the first point can be determined to be based on 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 corresponding to the second point during the output duration is large. Therefore, the cause of the zero pressure output value corresponding to the first point can be determined to be based on the pedestrian walking and stepping.

[0055] In addition, based on the above content, it can be seen that in this embodiment, the corresponding assembly pavement component can be spliced from multiple assembly pavement units. It can be explained that, since the assembly pavement component is spliced from multiple assembly pavement units, when a pedestrian steps on a certain assembly pavement unit and causes a tilt phenomenon, if the road areas corresponding to other assembly pavement units also have corresponding depressed areas, the corresponding other assembly pavement units may be driven to also cause a tilt phenomenon. Therefore, based on this propagation characteristic, it can be determined whether other assembly pavement units also have corresponding depressed areas. Specifically, the corresponding method steps are as follows: In response to the output duration of the first point being a valid acquisition value, each unit corner point located in other assembly and paving units having an adjacent relationship with the unit corner point corresponding to the first point is determined, and the detection point corresponding to each unit corner point is determined as a third point; Obtaining a starting time of the corresponding output duration, and determining a pressure acquisition value outputted at each third point based on the starting time; In response to the pressure collection value corresponding to any third point being zero, a corresponding output duration is obtained, and the output duration is determined as a valid collection value associated with the third point and corresponding to the pedestrian stepping.

[0056] For example, in this embodiment, obtaining corresponding valid collection values for detection points corresponding to other assembly and pavement components based on corresponding splicing relationships can be specifically implemented in the following manner: First, each unit corner point adjacent to the unit corner point corresponding to the first point and located in a different assembly pavement unit can be determined based on the assembly pavement component, and each determined unit corner point can be further determined as a third point. Then, the starting time of the corresponding output duration is obtained, and based on the starting time, the pressure acquisition value output at each third point is determined. By using the starting time as the time anchor point, the collected pressure data can be ensured to be time synchronized. Finally, if the pressure collection value corresponding to any third point is zero, it indicates that there is also a corresponding concave area in the road area of the assembly paving unit corresponding to the third point. At this time, the output duration of the corresponding third point can be determined as the corresponding valid collection value.

[0057] In step S203, the following contents are included: The road state corresponding to the damaged road is determined based on the valid collected values, and an early warning signal is sent to the management end when the road state is a sunken state.

[0058] For example, in this embodiment, based on the above content, it can be known that the longer the corresponding output duration, the greater the corresponding degree of depression should be. Therefore, after obtaining the corresponding valid collection value, the road state of the damaged road can be further determined based on the valid collection value; and further, when it is determined that the road state is a depressed state, a corresponding early warning signal is sent to the management end to remind the management end to perform routine repairs on the damaged road in a timely manner.

[0059] Furthermore, in this embodiment, the above-mentioned “determining the road state corresponding to the damaged road based on the valid collected values” may further include the following steps: Obtaining the effective number of all effective collected values corresponding to the same assembly and paving unit, and configuring the corresponding quantity weight based on the effective number to obtain a quantity evaluation value; Sum up all valid collected values corresponding to the same assembly and pavement unit, and compare the obtained total collected value with the retrieved preset interval table, wherein the preset interval table includes different value intervals; Performing weight configuration of the total value of the collection according to the numerical interval of the total value of the collection, and obtaining a numerical evaluation value; Summing the quantity evaluation value and the numerical evaluation value, and determining the filling attribute of the corresponding assembly and pavement unit based on the obtained total evaluation value; A road state corresponding to the damaged road is determined based on the filling attribute corresponding to each assembly pavement unit.

[0060] For example, in this embodiment, after obtaining the valid collection value of the corresponding assembly and paving unit, the road status of the corresponding damaged road can be further determined based on the following method steps: First, after completing the acquisition of the pressure collection values of each detection point corresponding to the same assembly paving unit, in order to comprehensively evaluate the road area corresponding to the assembly paving unit, the corresponding effective quantity can be obtained based on all the effective collection values corresponding to the assembly paving unit, and the corresponding quantity weight can be configured based on the effective quantity. It can be seen that when the effective quantity is greater, it means that the assembly paving unit has more detection points with zero output pressure collection values, that is, the degree of depression of the corresponding depressed area should be greater. Therefore, by configuring weights with different quantity weights, a reasonable evaluation based on the quantity dimension can be performed; for example, when the effective quantity is 4, the corresponding quantity weight can be 0.6, and when the corresponding effective quantity is 3, the corresponding quantity weight can be 0.4. By configuring the effective quantity and the corresponding quantity weight, the quantity evaluation value of the corresponding quantity dimension can be obtained; Then, after completing the evaluation of the quantity dimension, a reasonable evaluation can also be performed based on the numerical dimension. That is, all valid collected values corresponding to the same assembly and pavement unit can be summed up and the obtained total collected value can be compared with the retrieved preset interval table. The preset interval table includes different numerical intervals. The sum of the valid collected values can obtain the comprehensive data index of the numerical dimension corresponding to the assembly and 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 lighter road damage, and in another interval represents heavier damage. By comparing the total collected value with the preset interval table, the extent of road damage can be preliminarily judged. Next, the collected total values are assigned corresponding numerical weights based on the numerical intervals in which they fall, to obtain a numerical evaluation value. Different numerical intervals reflect different road damage conditions. Assigning corresponding numerical weights to each interval can more accurately measure the degree of road damage represented by the collected total values. For example, a collected total value in a severely damaged interval has a higher numerical weight and a corresponding higher numerical evaluation value. This further refines the assessment of road conditions and makes the assessment results more accurate. Afterwards, the quantity evaluation value and the numerical evaluation value corresponding to the same assembly paving unit obtained above are summed up, and the filling attribute of the corresponding assembly paving unit is determined based on the obtained total evaluation value, that is, based on a comprehensive consideration of the quantity evaluation value and the numerical evaluation value, a comprehensive evaluation can be performed based on the quantity dimension and the numerical dimension, and the filling attribute is determined by the total evaluation value. Here, the filling attribute may include a dangerous attribute and a safe attribute, which can be specifically 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 may be a dangerous attribute, and when the total evaluation value is less than or equal to the preset evaluation value, the corresponding filling attribute may be a safe attribute. It should be noted that the assembly paving unit corresponding to the dangerous attribute can be understood as not being recommended for pedestrians to walk on, and the assembly paving unit corresponding to the safe attribute can be understood as being established for pedestrians to walk on; Finally, after completing the determination of the filling attributes corresponding to each assembly pavement unit, the filling attributes of each assembly pavement unit that constitutes the assembly pavement component can be summarized and analyzed to determine the road status of the corresponding damaged road. In the subsequent process, based on the road status, it can be determined whether it is necessary to send a 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 to ensure the safety and smooth flow of the road.

[0061] Furthermore, in this embodiment, the above-mentioned “determining the road state corresponding to the damaged road based on the filling attribute corresponding to each assembly paving unit” may further include the following steps: Obtaining an extension direction of the corresponding damaged road, and sorting the assembly pavement units constituting the assembly pavement component from near to far based on the extension direction to obtain a unit sequence; When it is determined based on the unit sequence that each sequence position has an assembly paving unit whose corresponding filling attribute is a safety attribute, the assembly paving units corresponding to the safety attribute are connected along the extension direction based on the adjacent relationship to obtain a connection route; In response to the connecting route penetrating the damaged road in the extending direction, the road state of the damaged road is determined to be a flat state, otherwise it is determined to be a sunken state.

[0062] For example, in this embodiment, after completing the filling attributes of each assembly pavement unit that constitutes the assembly pavement component, the road status of the corresponding damaged road can be determined based on the following method steps: First, based on real-world scenarios, the road sections where damaged roads are located generally have corresponding extension directions, that is, the travel direction of the road section. Therefore, the extension directions of the corresponding damaged roads can be used to sort the assembly pavement units from near to far to obtain the corresponding unit sequence; 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 that needs to be filled for the 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 at the same sequence position can be determined according to the unit sequence, wherein, when the filling attributes of all assembly pavement units corresponding to the same sequence position are all dangerous attributes, it indicates that the current damaged road has become impassable. At this time, it is necessary to determine the road state of the damaged road as a sunken state; similarly, when it is determined based on the unit sequence that each sequence position has an assembly pavement unit whose corresponding filling attribute is a safety attribute, the assembly pavement units corresponding to the safety attribute can be connected based on the adjacent relationship along the extension direction to obtain the corresponding connection route; 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 used for normal pedestrian traffic. Therefore, the road state corresponding to the damaged road can be determined as a flat state, otherwise it can be determined as a sunken state.

[0063] In summary, according to the method of this embodiment, firstly, in terms of the timeliness of road maintenance, when a damaged road is detected, the assembled paving components respond quickly to fill it, and the damaged part of the road can be repaired in the first time to facilitate pedestrians to pass, thereby reducing road maintenance costs and extending the overall service life of the road; secondly, in terms of the accuracy of road status monitoring, by establishing a corner point connection line between the unit corner point and the center point of the assembled paving unit and determining the detection points along it, a scientific and uniform layout is provided for pressure collection. This layout can fully cover the damaged road and obtain more representative pressure data, and pressure is collected at each detection point, and the effective collection value corresponding to the pedestrian stepping is obtained based on the collection result, which can keenly capture the subtle changes in the road surface, because the pedestrian's stepping force and frequency The rate is relatively stable. By analyzing these valid collected values, the actual condition of the road can be accurately judged, especially whether there are potential hazards such as road depressions. Compared with traditional manual inspection methods, 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 status is determined based on the valid collected values, and a warning signal is sent to the management end in a timely manner when the road status is depressed, which greatly improves the road safety guarantee capability. After receiving the warning signal, the management end can quickly arrange for professional personnel to handle it, such as repairing the depressed area and setting up warning signs, etc., to avoid safety accidents such as pedestrians falling and getting injured due to road depressions. At the same time, this also helps road management departments establish a complete road safety file and make more scientific plans and decisions on road maintenance and management.
