Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Any embodiment described as "exemplary" in this invention is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed herein.
[0049] Deflectometers are commonly used in airport pavement PCN calculations, pavement structural remaining service analysis, and evaluation of void conditions and joint load transfer in cement concrete pavements, among other pavement structural load-bearing capacity assessments. Because deflectometers are heavy, they require a tractor for loading or movement. In field operations, workers use a tractor to move the deflectometer to the testing point on the pavement section to be tested, and the testing point location needs to be manually determined, which is labor-intensive and time-consuming, and hinders the development of automated deflectometer testing.
[0050] Based on this, the method, apparatus, electronic device, and storage medium for determining the location of pavement inspection points provided in this embodiment of the invention, after acquiring the size information of each pavement panel to be tested, the size information of the deflectometer used to test the pavement, and the detection direction of the deflectometer, determine the center point of each pavement panel to be tested based on the size information of each pavement panel to be tested, and then determine the location of the inspection point of each pavement panel to be tested based on the center point of each pavement panel to be tested, the detection direction, and the size information of the deflectometer. Thus, based on the size information of each pavement panel to be tested, the size information of the deflectometer, and the detection direction of the deflectometer, the location of the inspection points on the pavement to be tested can be generated quickly and accurately.
[0051] Please see Figure 1 , Figure 1 This is a structural block diagram of an electronic device 100 provided in this embodiment. Figure 1 As shown, the electronic device may include a device 10 for determining the location of pavement inspection points, a memory 20, a processor 30, and a communication unit 40. The memory 20 stores machine-readable instructions that can be executed by the processor 30. When the electronic device 100 is running, the processor 30 and the memory 20 communicate via a bus. The processor 30 executes the machine-readable instructions and performs the method for determining the location of pavement inspection points.
[0052] The memory 20, processor 30, and communication unit 40 are electrically connected directly or indirectly to each other to achieve signal transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines. The device 10 for determining the location of pavement inspection points includes at least one software function module that can be stored in the memory 20 in the form of software or firmware. The processor 30 is used to execute the executable module (e.g., the software function module or computer program included in the device 10 for determining the location of pavement inspection points) stored in the memory 20.
[0053] The memory 20 may be, but is not limited to, random access memory (RAM), read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), etc.
[0054] In some embodiments, processor 30 is used to perform one or more functions described in this embodiment. In some embodiments, processor 30 may include one or more processing cores (e.g., a single-core processor (S) or a multi-core processor (S)). By way of example only, processor 30 may include a central processing unit (CPU), an application-specific integrated circuit (ASIC), an application-specific instruction-set processor (ASIP), a graphics processing unit (GPU), a physical processing unit (PPU), a digital signal processor (DSP), a field-programmable gate array (FPGA), a programmable logic device (PLD), a controller, a microcontroller unit, a reduced instruction set computing (RISC) computer, or a microprocessor, or any combination thereof.
[0055] For ease of explanation, only one processor is described in electronic device 100. However, it should be noted that electronic device 100 in this embodiment may also include multiple processors, and therefore the steps performed by one processor as described in this embodiment may also be performed jointly or individually by multiple processors. For example, if the server's processor performs steps A and B, it should be understood that steps A and B may also be performed jointly by two different processors or individually by one processor. For example, one processor performs step A, and a second processor performs step B, or the first and second processors jointly perform steps A and B.
[0056] In this embodiment, the memory 20 is used to store the program, and the processor 30 is used to execute the program after receiving the execution instruction. The process definition method disclosed in any implementation of this embodiment can be applied to the processor 30, or implemented by the processor 30.
[0057] The communication unit 40 is used to establish a communication connection between the electronic device 100 and other devices via a network, and to send and receive data via the network.
[0058] In some implementations, the network can be any type of wired or wireless network, or a combination thereof. By way of example only, the network may include wired networks, wireless networks, fiber optic networks, telecommunications networks, intranets, the Internet, local area networks (LANs), wide area networks (WANs), wireless local area networks (WLANs), metropolitan area networks (MANs), public switched telephone networks (PSTNs), Bluetooth networks, ZigBee networks, or near field communication (NFC) networks, or any combination thereof.
[0059] In this embodiment, the electronic device 100 may be, but is not limited to, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), or other electronic devices. This embodiment does not impose any restrictions on the specific type of electronic device. The electronic device in this embodiment may be a control device for remotely controlling the pavement inspection robot, or it may be a control module installed inside the robot for determining pavement inspection points. Any electronic device capable of executing a method for determining the location of pavement inspection points is acceptable. This embodiment does not specifically limit the specific connection relationship between the electronic device and the pavement inspection robot; those skilled in the art can adjust it according to their needs.
[0060] Understandably, Figure 1 The structure shown is for illustrative purposes only. The electronic device 100 may also have... Figure 1 Showing more or fewer components, or having with Figure 1 The different configurations shown. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof.
[0061] based on Figure 1 The implementation architecture of this embodiment provides a method for determining the location of pavement detection points, which is based on... Figure 1 The electronic device executes, based on the following Figure 1 The provided structural diagram of the electronic device 100 details the method for determining the location of pavement detection points provided in this embodiment. Please refer to the attached diagram. Figure 2The method for determining the location of pavement detection points provided in this embodiment includes steps S101 to S103.
[0062] S101: Obtain the dimensional information of each pavement panel to be tested in the pavement surface to be tested, the dimensional information of the deflectometer used to test the pavement surface to be tested, and the testing direction of the deflectometer.
[0063] In this embodiment, the pavement to be tested can be an airport pavement, highway pavement, or other cement concrete pavement. To prevent irregular cracks caused by thermal expansion and contraction, cement concrete pavements need to be divided into sections. Since roads are of uniform width, dividing the cement concrete pavement results in multiple rectangular pavement panels of the same width. The lengths of these rectangular pavement panels can be the same or different. For example: Please refer to the following... Figure 3 The pavement to be tested is a highway with a single lane and a width of A. It is not divided in the width direction, but is divided along its length to obtain pavement blocks 1, 2, 3, and 4, each with a width of A. The lengths of pavement blocks 1, 2, 3, and 4 are all different. It is understood that when the pavement to be tested has multiple lanes or a large width, it is necessary to divide it in the width direction. In this embodiment, each pavement block to be tested refers to the pavement block among multiple pavement blocks that needs to be tested for deflection. Each pavement block in the pavement to be tested can be subjected to deflection testing, or a testing interval can be set to determine the pavement blocks to be tested in the pavement to be tested. The testing interval can be a specific distance or the number of blocks in between; this embodiment does not impose a specific limitation.
[0064] In this embodiment, the dimensional information of each pavement panel block to be tested in the pavement surface can be obtained in advance. This can be achieved through direct measurement, or by establishing a coordinate system with a point on the pavement surface as the origin, determining the coordinates of the vertices of each pavement panel block, and thus obtaining its dimensional information. This embodiment does not impose any limitation on this method. In this embodiment, the dimensional information of each pavement panel block to be tested can be the same or different. When the dimensions of all pavement panel blocks to be tested in the pavement surface are the same, when pre-collecting the dimensional information of each pavement panel block to be tested, only the dimensional information of any one pavement panel block needs to be collected.
[0065] In this embodiment, the deflectometer can be a falling weight deflectometer or a heavy-duty falling weight deflectometer. In this embodiment, the detection point position of the pavement under test represents the deflection detection point position of the pavement under test, that is, the detection point position of the deflection sensor at the center of the deflectometer's support plate. In this embodiment, the detection direction of the deflectometer is the direction in which the deflectometer moves forward. The dimensional information of the deflectometer refers to the dimensional information during the deflectometer test, including the installation distance between the first and second deflection sensors, the radius of the support plate, and other dimensional information affecting the deflectometer's detection. This embodiment does not impose limitations, and those skilled in the art can adjust it according to requirements. The installation distance between the first and second deflection sensors is determined according to the detection purpose and the type of pavement under test. For example, when the pavement to be tested is an airport pavement and joint load transfer test is being performed, the deflection sensor located at the center of the bearing plate of the falling weight deflectometer is required to be 150mm away from the joint of each pavement panel to be tested, and there is another deflection sensor 150mm away from the joint. In this case, if the diameter of the bearing plate is 300mm, the joint is located at the edge of the bearing plate and 150mm away from the deflection sensor at the center of the bearing plate.
[0066] S102: Determine the center point of each track panel block to be tested based on the size information of each track panel block to be tested.
[0067] In this embodiment, after establishing a coordinate system with any point on the pavement to be tested as the origin, the size information of each pavement panel to be tested is determined. Based on the size information of each pavement panel to be tested, the coordinates of the center point of each pavement panel to be tested can be determined. In this embodiment, since the pavement to be tested is a cement concrete pavement such as an airport runway or a highway, when the pavement to be tested is a straight section, the resulting pavement panel to be tested is a regular rectangle. In this case, the center point of the pavement panel to be tested can be determined based on the size information of the pavement panel to be tested. When the pavement to be tested includes curved sections, the curved sections have curvature. The center point of the pavement panel to be tested can be determined by measuring the size of the smallest bounding rectangle of the pavement panel to be tested located in the curved section, and then using the center point of the smallest bounding rectangle as the center point of the pavement panel to be tested.
[0068] S103: Determine the location of the detection point for each track panel block to be tested based on the center point, detection direction, and dimensions of the deflectometer.
[0069] In this embodiment, to comprehensively reflect the deflection test results of each track panel segment, the test point positions for each segment include both center-of-slab and edge-of-slab test points. For simplified calculation, the center point of each track panel is used as the center-of-slab test point. In practical applications, the center-of-slab test point can be a point within a circle of a preset radius centered on the center point of each track panel segment. As long as the deflection test results at the center of the segment can be represented within this circle, it is acceptable. In this embodiment, the preset radius can be determined by those skilled in the art based on testing accuracy and the control accuracy of the deflectometer; this embodiment does not impose specific limitations. In this embodiment, the direction from the center-of-slab test point to the edge-of-slab test point is the testing direction of the deflectometer. Based on the dimensions and testing direction of the deflectometer, the edge-of-slab test point positions of each track panel segment are determined to ensure that the edge-of-slab test point positions meet the testing requirements.
[0070] In this embodiment, after generating the detection point positions of each track panel block to be tested, a detection line can be generated according to the detection direction, and the detection line can be used to control the detection of the deflection meter.
[0071] In this embodiment, the detection point position of the deflector on each pavement panel to be tested is determined by the size information of each pavement panel to be tested, the size information of the deflector, and the detection direction of the deflector. Under the premise of ensuring the detection requirements, the detection point position of each pavement panel to be tested can be generated quickly and accurately.
[0072] Optionally, in this embodiment, the step of obtaining the size information of each pavement panel block to be tested in the pavement surface to be tested includes:
[0073] Establish a coordinate system with any point on the pavement to be measured as the origin;
[0074] Determine the coordinate information of the vertices of each track panel block to be tested in the coordinate system, and determine the size information of each track panel block to be tested based on the coordinate information of the vertices of each track panel block to be tested in the coordinate system.
[0075] In this embodiment, when obtaining the size information of each pavement panel block to be tested in the pavement surface to be tested, a coordinate system is first established with any point on the pavement surface to be tested as the origin. Then, the coordinate information of the vertices of each pavement panel block to be tested in this coordinate system is determined, thereby obtaining the size information of each pavement panel block to be tested. If the size information of each pavement panel block to be tested is the same, that is, only the coordinates of the vertex of one pavement panel block to be tested in this coordinate system need to be determined to obtain the size information of each pavement panel block to be tested. For example: Please refer to the following... Figure 4If the pavement to be measured is an airport runway concrete slab, and all the pavement slabs to be measured have the same size, take the corner of the first pavement slab to be measured on the north side of the runway centerline as the origin of the coordinate system, the corresponding slab joint as the y-axis (positive direction pointing to the outside of the runway), and the joint between the two slabs in the center of the runway as the x-axis (positive direction pointing to the direction of the survey line), which is the centerline of the runway centerline, and establish a two-dimensional plane rectangular coordinate system xoy. Based on the initial slab size information, the coordinate information of other slabs can be further determined.
[0076] Optionally, in this embodiment, the dimensional information of the deflection meter includes the installation distance between the first deflection sensor and the second deflection sensor. The first deflection sensor is set at the center of the support plate of the deflection meter, and the second deflection sensor is set on the sensor beam fixedly connected to the support plate. The step of determining the detection point position of each track panel to be tested based on the center point, detection direction, and dimensional information of the deflection meter includes:
[0077] Based on the installation spacing and the detection direction, the edge detection line of each panel to be tested is determined;
[0078] Based on the edge detection lines of each track panel block to be tested and the center point of each track panel block to be tested, the positions of the edge detection points and the center detection points of each track panel block to be tested are determined.
[0079] In this embodiment, the installation spacing is the distance between the first deflection sensor and the second deflection sensor. The first deflection sensor is located at the center of the bearing plate of the deflectometer, and the second deflection sensor is located on the sensor beam fixedly connected to the bearing plate. Please refer to the following reference. Figure 5 The falling weight deflectometer uses multiple deflection sensors 2. In this embodiment, the first deflection sensor 21 is a deflection sensor located at the center of the support plate 1, and multiple deflection sensors 2 are also installed on the sensor beam (not shown in the figure) fixedly connected to the support plate. The second deflection sensor 22 is the deflection sensor on the sensor beam adjacent to (closest to) the first deflection sensor 21. When the falling weight deflectometer performs testing, a falling weight 3 of a certain mass is raised to a certain height and then dropped freely. The impact force acts on the support plate 1 and is transmitted to the track surface to be tested, thereby applying a pulse load to the track surface to be tested, causing instantaneous deformation of the track surface. The deflection sensors 2, distributed at different distances from the detection point, detect the deformation of the structural layer surface. When the first deflection sensor 21 located at the center of the support plate 1 performs testing at the edge detection point, it is equidistant from the second deflection sensor 22 across the joint, that is, the joint of each track panel to be tested is located between the two deflection sensors, which can simultaneously meet the needs of edge detection such as void testing and joint load transfer testing.
[0080] To meet the testing requirements, in this embodiment, the edge detection line of each panel to be tested is determined based on the installation spacing and testing direction. That is, any point on the edge detection line can be used as the edge detection point to meet the above testing requirements. In this embodiment, the center detection point is the center point of each panel to be tested. As described in the previous embodiment, points within a circle of a preset radius, using the center point of each panel as the center point, can all be used as center detection points. In this embodiment, the edge detection point is taken from the edge detection line, and any point on the edge detection line can meet the testing requirements.
[0081] Optionally, in this embodiment, the position of the detection point on the edge of the board is set to be on a straight line with the position of the detection point in the middle of the board.
[0082] In this embodiment, to facilitate detection, the detection point positions at the edge of the board and the detection point positions in the middle of the board are set on the same straight line. When the detection point in the middle of the board is the center point of each panel to be tested, the midpoint of the detection line at the edge of the board is taken as the detection point position. When the detection point in the middle of the board is any point within a preset radius, a point on the detection line at the edge of the board that is on the same straight line as the detection point in the middle of the board is taken as the detection point position at the edge of the board.
[0083] Optionally, in this embodiment, the step of determining the edge detection line of each panel to be tested based on the installation spacing and detection direction includes:
[0084] Based on the detection direction, the detection endpoint boundary of each track panel block to be tested is determined;
[0085] Based on the installation spacing and the detection endpoint boundary of each track panel block to be tested, the edge detection line of each track panel block to be tested is determined.
[0086] The distance between the edge detection line of each track panel to be tested and the detection endpoint boundary of each track panel to be tested is equal to half of the installation spacing, and the direction from the edge detection line of each track panel to the detection endpoint boundary of each track panel to be tested is the detection direction.
[0087] In this embodiment, given the known detection direction of the deflection meter, the detection endpoint boundary of each test panel can be determined. Therefore, the panel edge detection line should be a point close to the panel edge detection boundary. According to the detection requirements described in the preceding embodiment, to ensure that the first deflection sensor at the center of the deflection meter's bearing plate and its adjacent second deflection sensor are equidistantly arranged across the plate seam, the distance between the panel edge detection line and the detection endpoint boundary must be equal to half the installation distance between the first and second deflection sensors.
[0088] Optionally, in this embodiment, the step of determining the position of the edge detection point and the position of the center detection point of each track panel block to be tested based on the edge detection line of each track panel block and the center point of each track panel block to be tested includes:
[0089] Determine the perpendicular line from the center point of each track panel to the edge detection line of each track panel;
[0090] The intersection of the perpendicular line of the edge detection line of each track panel block to be tested with the edge detection line of each track panel block to be tested is set as the edge detection point of each track panel block to be tested, and the center point of each track panel block to be tested is set as the center detection point of each track panel block to be tested.
[0091] In this embodiment, when the detection point position in the middle of each track panel block to be tested is the center point of each track panel block to be tested, the position of the edge detection point can also be determined by determining the perpendicular line between the center point of each track panel block to be tested and the edge detection line of each track panel block to be tested. The intersection of the perpendicular line between the edge detection line of each track panel block to be tested and the edge detection line of each track panel block to be tested is the position of the edge detection point of each track panel block to be tested.
[0092] Optionally, in this embodiment, the pavement panels to be tested are arranged in an array, and the size information of each pavement panel is the same. The size information of the deflection meter includes the installation distance between the first deflection sensor and the second deflection sensor. The first deflection sensor is set at the center of the support plate of the deflection meter, and the second deflection sensor is set on the sensor beam fixedly connected to the support plate. The steps based on the center point of each pavement panel to be tested, the detection direction, and the size information of the deflection meter include:
[0093] Take any row of lane panel blocks on the pavement to be tested as the target lane panel block, and determine the edge detection line of each lane panel block to be tested in the target lane panel block according to the installation spacing and detection direction.
[0094] Based on the edge detection lines and center points of each lane panel block to be tested in the target lane panel block, the positions of the edge detection points and the center detection points of each lane panel block to be tested in the target lane panel block are determined.
[0095] The detection offset distance of each lane panel block to be tested in the target lane panel block is determined based on the distance between the detection point position in the middle of the panel and the detection point position on the edge of the panel.
[0096] Based on the detection offset distance of each test panel in the target lane panel block and the center point of each test panel in other lane panel blocks, the positions of the edge detection points and the center detection points of each test panel in other lane panel blocks are determined.
[0097] In particular, when the pavement to be tested is wide, the pavement panels are arranged in an array, and the size information of each pavement panel is the same, the edge detection line of each pavement panel to be tested in the target pavement panel is determined according to the installation spacing and the detection direction. Then, based on the edge detection line of each pavement panel to be tested in the target pavement panel and the center point of each pavement panel to be tested, the method of obtaining the edge detection point position and the center detection point position of each pavement panel to be tested in the target pavement panel is as described in the previous embodiment, and will not be repeated here.
[0098] Optionally, in this embodiment, the step of determining the position of the edge detection point and the position of the center detection point of each lane panel block to be tested in the target lane panel block, based on the edge detection line of each lane panel block to be tested and the center point of each lane panel block to be tested, includes:
[0099] Based on the edge detection line of the initial test panel block and the center point of the initial test panel block, the positions of the edge detection point and the center detection point of the initial test panel block are determined.
[0100] The detection offset distance between the edge detection point position and the center detection point position of the initial test panel block is calculated.
[0101] Based on the center point of each test panel in the target lane panel block and the detection offset distance, the position of the edge detection point of each test panel in the target lane panel block is determined.
[0102] In this embodiment, since the pavement panels to be tested are arranged in an array and each panel has the same size, the detection offset distance of each panel to be tested in the target pavement panel is equal to the detection offset distance of the initial panel to be tested. Based on the center point and detection offset distance of each panel to be tested in the target pavement panel, the position of the edge detection point of each panel to be tested in the target pavement panel can be determined. For example: Please refer to... Figure 6 The airport pavement is arranged in an array of pavement panels, with each row containing multiple pavement panels, and correspondingly, multiple pavement panels to be tested. When conducting joint load transfer tests, the deflection sensor at the center of the bearing plate and its adjacent deflection sensors are required to be equidistant from each other on both sides of the joint, with a distance of 150mm. The diameter of the bearing plate for the deflectometer is generally 300mm or 400mm. If the diameter of the bearing plate in this embodiment is 300mm, then the installation spacing of the deflectometers is equal to the diameter of the bearing plate. Following the method described in the aforementioned embodiment, a system is established as follows... Figure 6 The coordinate system xoy is shown. Based on the size information of each track panel block, the coordinates of the initial detection point position in the middle of the target track panel block are determined as P in the coordinate system. c 0(L / 2, W / 2), where L and W are the length and width of the pavement panel, respectively. If the detection interval is s, the detection point positions P in the middle of the subsequent pavement panel to be tested are generated sequentially using the detection interval. c 1 P c 2 ... P c n If it exceeds the test area range (i.e., P) c n+1 If the x-axis coordinate is greater than the test area length Lmax, then the position of the detection point in the previous plate is taken as the position of the detection point in the last plate, and the coordinates of the detection point positions in each plate are P. c n (x c n ,y c n The calculation formula for ) is as follows:
[0103] x c i =L / 2+(s+1)*L*i,y c i =W / 2, i = 1, 2, ..., n
[0104] Where s represents the detection interval, that is, the interval between two adjacent deflection test blocks is s blocks, where s is a positive integer ≥ 0; n represents the number of pavement blocks to be tested besides the initial test block, i = 1, 2, ..., n. It is understandable that the example given here uses the first pavement block to the left of the target pavement block as the initial test block, and L / 2 is used in the calculation when applying the above formula. If the first pavement block to the left of the target pavement block is not used as the initial test block, the coordinates of the initial test block along the length of the pavement block are used for calculation, i.e., the coordinates along the X-axis.
[0105] In this embodiment, when determining the position of the edge detection point of the initial test lane panel block based on the edge detection line of the initial test lane panel block and the center point of the initial test lane panel block, according to the detection requirements, the distance between the edge detection line of each test lane panel block and the boundary of the detection endpoint is half the diameter of the bearing plate. For ease of detection, the edge detection point position is taken as the midpoint of the edge detection line. Therefore, the calculation formula for the detection offset distance Bia of the initial test lane panel block is as follows:
[0106] Bia = q(L / 2 - D / 2)
[0107] Where q is the offset direction vector, which is 1 when the detection direction of the deflectometer is the same as the x-axis, and -1 when it is opposite. This yields the initial coordinates x of the detection point position on the edge of the target pavement panel. e n =L / 2+Bia,P e 0 (LD / 2, W / 2).
[0108] Since the detection offset distance of each track panel to be tested is the same as the detection offset distance of the initial track panel to be tested, which is Bia, the edge detection point position P of the track panel to be tested other than the initial track panel to be tested is determined. e 1 P e 2 ... P e n coordinates P e n (x e n ,y e n The calculation formula is as follows:
[0109] x c i =L / 2+Bia+(s+1)*L*i,y c i =W / 2, i = 1, 2, ..., n
[0110] When the pavement panels to be tested are arranged in an array and the size information of each pavement panel is the same, the above calculation method can quickly and accurately calculate the detection point position of each pavement panel to be tested in the target pavement panel.
[0111] In this embodiment, after determining the detection point positions of each test panel in the target aisle panel block, the detection directions of other aisle panel blocks and the center points of each test panel in other aisle panel blocks are known. The detection offset distance of each test panel in other aisle panel blocks is also the same as the initial detection offset distance of the test panel in the target aisle panel block. Therefore, based on the center points and detection offset distances of each test panel in other aisle panel blocks, the positions of the detection points in the middle of the panel and the detection points on the edges of the panel can be determined.
[0112] Optionally, in this embodiment, the step of determining the edge detection point position and the center detection point position of each lane panel to be tested in other lane panels based on the detection offset distance of each lane panel to be tested in the target lane panel block and the center point of each lane panel to be tested in other lane panels includes:
[0113] Determine the center point of each lane panel block to be tested in other lane panel blocks, and set the center point of each lane panel block to be tested in other lane panel blocks as the detection point position in the middle of each lane panel block to be tested in other lane panel blocks;
[0114] Based on the center point of each test panel in other roadway panels, the detection offset distance of each test panel in the target roadway panel, and the detection direction of the deflection meter in other roadway panels, the position of the edge detection point of each test panel in other roadway panels is determined.
[0115] In this embodiment, the corresponding detection point position in the center of each test panel in the other lane panel blocks is the center point of each test panel block. Knowing the center detection point positions in the other lane panel blocks, the edge detection point positions can be determined based on the detection offset distance and the detection direction of the deflection meter in the other lane panel blocks. For example: Please refer to... Figure 6 When the detection direction of adjacent lane panel blocks in the positive y-axis direction of the target lane panel block is the same as that of the target lane panel block, the detection points do not need to be staggered, and the detection interval of the lane panel blocks to be tested in each lane panel block is the same, when determining the center-of-board and edge-of-board detection point positions of each lane panel block to be tested in other lane panel blocks, simply add W / 2 to the y-axis coordinates of the center-of-board and edge-of-board detection point positions of each lane panel block to be tested in the target row. If staggered arrangement is required and / or the detection interval in other lane panel blocks is different from that of the target lane panel block, then based on the staggered arrangement and / or the detection interval in other lane panel blocks, determine the translation amount in the x-axis direction of the center-of-board and edge-of-board detection point positions of each lane panel block to be tested in other lane panel blocks, while the translation amount in the y-axis direction remains W / 2.
[0116] Optionally, in this embodiment, the deflection meter detects in opposite directions in two adjacent lane panels, and the detection interval between two adjacent lane panels is the same. The step of determining the center point of each lane panel to be tested in other lane panels includes:
[0117] Based on the center point of each lane panel to be tested in the target lane panel block and the detection interval of the lane surface to be tested, the position of the detection point in the middle of each lane panel to be tested in other lane panel blocks is determined.
[0118] Based on the position of the detection point in the middle of each lane panel block to be tested in other lane panel blocks and the detection offset distance of each lane panel block to be tested in the target lane panel block, the position of the detection point on the edge of each lane panel block to be tested in other lane panel blocks is determined.
[0119] In this embodiment, the pavement panels to be tested are arranged in an array, and each panel has the same size information. To facilitate inspection, after inspecting any row of pavement panels, it is not necessary to turn back to the starting boundary of the pavement; instead, the instrument can move directly from the end boundary of that row to the next row. The deflectometer then inspects adjacent rows of pavement panels in the opposite direction, saving inspection time and improving efficiency. For example: Please refer to [reference needed]. Figure 6 The detection direction of the target lane panel is the positive x-axis, the detection interval is 3, and there are 3 panels between each lane panel to be tested. After the detection point positions of each lane panel to be tested in the target lane panel have been generated, the detection point position P in the merged panel is... c and the location P of the board edge detection point e This yields a complete deflection survey line Pn1 containing the locations of all detection points in and around the slab: [P c 0 ,P e 0 ,P c 1 ,P e 1 ,…,P c n ,P e n The subscript n1 indicates the first deflection measurement line north of the runway centerline. The detection direction of the adjacent lane panel block adjacent to the target lane panel block in the negative y-axis direction is the negative x-axis direction. After the detection is completed according to the detection line Pn1, in order to save time and avoid returning to the y-axis to start the detection again, the deflection meter can be directly moved from the end of the detection line Pn1 to the adjacent lane panel block for detection.
[0120] In this embodiment, the selection of each test panel in adjacent aisle panels only needs to meet the detection interval requirements. Therefore, in this embodiment, when the detection intervals in two adjacent aisle panels are the same, the generation of the detection point positions in each test panel in adjacent aisle panels can also be directly determined based on the detection point positions and detection intervals of each test panel in the target aisle panel.
[0121] With the origin of the coordinate system as the reference, the translation of the detection point position in each test panel of an adjacent lane panel block relative to the detection point position in each test panel block of the target lane panel block is Tx along the x-axis and Ty along the y-axis.
[0122] Tx = round((s+1) / 2) * L
[0123] Ty = W
[0124] Where round(·) is the rounding function, and W is the width of the module. For example: Please refer to [reference needed]. Figure 6 The detection interval is 3, and Tx = 2L. Tx = 2L represents the translation amount of the detection point position in the detection line Qn1 of the adjacent lane panel relative to the detection point position in the detection line Pn1 of the target lane panel, i.e., P c 0 With Q c n P c 1 With Q c n-1 …P c n With Q c 0 The translation in the x-axis direction is 2L, and correspondingly, Ty characterizes P. c 0 With Q c n P c 1 With Q c n-1 …P c n With Q c 0 Translation in the y-axis direction.
[0125] After determining the coordinates of the detection points in the center of each adjacent lane panel block, the positions of the edge detection points of each adjacent lane panel block can be determined based on the detection offset distance of the target lane panel block and the detection distance of the deflection meter in that adjacent lane panel block. Please refer to [reference needed]. Figure 6 To facilitate continuous testing, the detection directions of the measuring lines on both sides of the runway centerline are opposite. Therefore, it is necessary to change the value of q in the detection offset distance based on the detection direction (negative x-axis direction) of the deflectometer on the adjacent pavement panel, with q set to -1. Based on the detection offset distance and the detection direction of the deflectometer on the adjacent pavement panel, the position of the edge detection point of each pavement panel to be tested in the adjacent pavement can be determined, ultimately yielding the complete Qn1 measuring line.
[0126] In this embodiment, the detection directions of two adjacent aisle panel blocks are set to opposite directions, which takes into account the continuity of detection and can improve detection efficiency.
[0127] The method for determining the location of pavement inspection points provided in this invention involves acquiring the size information of each pavement panel to be tested, the size information of the deflectometer used to inspect the pavement, and the detection direction of the deflectometer.
