When determining the abnormal moment, the relative deviation between the pressure data detected by the pressure sensor of each test wheel assembly at multiple moments and the initial pressure data can be used to determine whether the test wheel assembly has passed through the unevenness and whether the pressure sensor has detected abnormal pressure data, thereby accurately determining the abnormal moment, and providing an accurate data basis for the subsequent determination of the abnormal detection position and the determination of the flatness detection score. When determining the abnormal detection position, the influence of the width of the vertical test assembly and the distance between the test wheel and the vertical test assembly is considered, and the corresponding abnormal detection position with uneven conditions when the abnormal pressure data is detected is determined by the number of executions and the number of moments of the forward process, thereby improving the accuracy of the abnormal detection position. When determining the flatness detection score, the severity of the uneven condition of the abnormal connected domain can be reflected by the maximum unevenness of the abnormal connected domain and the severity of the uneven change, and the influence of the abnormal connected domain on the flatness of the area to be tested can be determined by the number of abnormal detection positions in the abnormal connected domain, thereby obtaining the flatness detection score of the area to be tested, so that the flatness detection score of the area to be tested can accurately and objectively express the overall flatness of the area to be tested.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The technical solution of the present invention is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0033] Figure 1 The following is a flow chart of a method for detecting the flatness of indoor decoration according to an embodiment of the present invention, wherein the method comprises:

[0034] Step S101, determining the number of connections of the test wheel assembly according to the size of the area to be tested, wherein each test wheel assembly includes a shell structure, and a connection structure is provided on the double side walls in the X direction outside the shell structure, which is used to connect with the connection structure of other test wheel assemblies or the connection structure of the vertical test assembly, and a spring assembly is installed in the shell, and a pressure sensor is provided at the upper end of the spring assembly, and a roller is provided at the lower end, and the rotation direction of the roller is the Y direction. A communication assembly is also installed in the shell, which is used to transmit the pressure data detected by the pressure sensor to the controller;

[0035] Step S102, connecting the connected number of test wheel assemblies in parallel through the connection structure of the test wheel assembly to form a test wheel assembly sequence, and connecting vertical test assemblies on both sides of the test wheel assembly sequence respectively, and installing the test wheel assembly sequence to both ends of the telescopic bracket through the connection structures of the vertical test assemblies on both sides, wherein the vertical test assembly includes a laser rangefinder for emitting laser vertically downward and measuring the distance between the laser rangefinder and the plane of the area to be tested below;

[0036] Step S103, placing the telescopic bracket on the plane of the area to be tested, and adjusting the angle between the test wheel assembly sequence and the plane of the area to be tested, so that the initial distance data measured by the laser rangefinders of the two vertical test assemblies are the same, and reading the initial pressure data of each pressure sensor through the controller;

[0037] Step S104, pushing the telescopic bracket forward at a preset speed, wherein during the forward movement, the forward movement direction is the Y direction, and during the forward movement, the distance measured by the laser rangefinder of the vertical test assembly maintains the initial distance data;

[0038] Step S105, reading pressure data detected by the pressure sensors of each test wheel assembly through the controller at multiple moments during the forward process;

[0039] Step S106, executing the forward process multiple times until the area swept by the test wheel assembly sequence can cover the area to be tested;

[0040] Step S107, determining a flatness detection score of the area to be tested according to the number of executions of the forward process, the preset speed, the pressure data and the initial pressure data;

[0041] Step S108, determining the flatness quality status of the interior decoration according to the flatness detection scores of the multiple areas to be tested.

[0042] According to the indoor decoration flatness detection method of the embodiment of the present invention, the number of connections of the test wheel assembly can be determined based on the size of the area to be tested, and the independent detachable test wheel assembly is used to connect according to the number of connections. The size of the test wheel assembly sequence can be flexibly adjusted based on the size of the area to be tested, thereby improving the adaptability to the areas to be tested of different sizes. And the vertical relationship between the test wheel assembly sequence and the plane of the area to be tested can be tested by the vertical test assembly to improve the detection accuracy. Further, the action of the roller when the test wheel assembly encounters a concave and convex position can be converted into pressure data through the combination of a spring assembly and a pressure sensor, thereby intuitively and easily detecting the degree of concave and convex positions of the concave and convex positions. For concave and convex positions with a small degree of concave and convexity that are not easy to detect by size measurement, accurate detection can also be performed, thereby improving the comprehensiveness and accuracy of the flatness detection.

[0043] According to an embodiment of the present invention, in step S101, the test wheel assemblies are independent and can be spliced ​​together to form a test wheel assembly sequence of larger size, or can be split to obtain a test wheel assembly sequence of smaller size.

[0044] Figure 2 A schematic diagram of a test wheel assembly according to an embodiment of the present invention is exemplarily shown.

[0045] According to one embodiment of the present invention, the test wheel assembly includes a housing structure, a communication assembly, a pressure sensor, a spring assembly, a connection structure and a roller. The housing structure includes a connection structure on both side walls in the X direction, which can be used to connect with other test wheel assemblies. Multiple test wheel assemblies are connected together to obtain a test wheel assembly sequence. The housing can be integrated with a communication assembly and a pressure sensor. When the test wheel assembly is placed on the plane of the area to be tested, the spring assembly is compressed due to its own weight, and the pressure sensor can detect the pressure data. As the roller rolls, the test wheel assembly moves forward in the Y direction. During the forward process, if a convexity or concave is encountered, the compression amplitude of the spring assembly will change, so that the pressure sensor detects different pressure data. Based on the different pressure data, it can be determined whether the test wheel assembly passes through an uneven position, thereby detecting the flatness of the plane of the area to be tested. Multiple test wheel assemblies are connected together to form a test wheel sequence, and the flatness of a larger area can be detected during one forward process. The pressure data detected by the pressure sensor can be sent to the controller in real time through the communication assembly, and the controller determines whether the position passed by the test wheel assembly is flat based on the pressure data.

[0046] According to one embodiment of the present invention, the number of connections of the test wheel assembly is determined according to the size of the area to be tested, including: setting a minimum number of connections; determining the width of the area to be tested according to the size of the area to be tested; determining the spacing distance between the rollers of the two test wheel assemblies when the two test wheel assemblies are connected; and determining the number of connections of the test wheel assembly according to the width of the area to be tested, the spacing distance and the minimum number of connections.

[0047] According to one embodiment of the present invention, a minimum number of connections may be set so that the test wheel assembly sequence forms a certain scale, thereby avoiding the problem that when the recessed area is large and the recessed degree is small, the entire test wheel assembly sequence is located within the recessed area, thereby failing to measure changes in pressure data when passing through the recessed area.

[0048] According to one embodiment of the present invention, the test wheel assembly sequence can be placed in a direction parallel to the width direction of the area to be tested and move along the length direction of the area to be tested to perform flatness detection. The width of the area to be tested can be obtained to determine the appropriate length of the test wheel assembly sequence, and then determine the number of test wheel assemblies to be connected.

[0049] According to one embodiment of the present invention, the number of connections of the test wheel assembly is determined according to the width of the test area, the spacing distance and the minimum number of connections, including: determining the number of connections of the test wheel assembly according to formula (1): ,

[0050] (1)

[0051] Wherein, W is the width of the area to be measured, is the width of the vertical test component, To preset the number of advances, is the spacing distance, is the minimum number of connections, round is a round-up function, and if is a conditional function.

[0052] According to one embodiment of the present invention, since vertical test assemblies are connected to both ends of the test wheel assembly sequence, when the test wheel sequence is placed in the width direction of the area to be tested, the two ends of the area to be tested in the width direction cannot be measured due to the existence of the vertical test assemblies. For example, the area to be tested is an indoor floor. When the test wheel sequence is placed at one end in the width direction for the first time, the vertical test assembly is close to the indoor wall, resulting in a distance at one end of the area to be tested in the width direction that cannot be measured by the test wheel assembly sequence. The length of this distance is the width of the vertical test assembly. Similarly, when the test wheel assembly sequence is placed at the other end in the width direction for the last time, the vertical test assembly is close to the indoor wall, resulting in a distance at the other end in the width direction that cannot be measured by the test wheel assembly sequence. Therefore, the measured length in the width direction of the area to be tested is .

[0053] According to one embodiment of the present invention, It is the length swept in the width direction of the test area each time the test wheel assembly sequence moves forward. It can also represent the length of the part of the test wheel assembly sequence excluding the vertical test assembly. That is, the number of test wheel components included in the length. In formula (1), the conditional function can be expressed as follows: If holds, then the conditional function value is , otherwise If the number of test wheel assemblies included in the length is less than or equal to the minimum connection number, the connection number of the test wheel assemblies is determined as the minimum connection number, and the connection number of the test wheel assemblies is not less than the minimum connection number. On the contrary, if the above conditions are not met, Round up to get Closest, and greater than or equal to The integer is the number of connections for the test wheel assembly.

[0054] In this way, the minimum number of connections can be set to avoid the problem that when the recessed area is large and the recessed degree is small, the entire test wheel assembly sequence is located within the recessed area and the change in pressure data cannot be measured. When calculating the number of connections of the test wheel assembly, the width of the vertical test assembly is taken into account, thereby improving the accuracy of the number of connections of the test wheel assembly and improving the adaptability to test areas of different sizes.

[0055] According to one embodiment of the present invention, in step S102, after the number of connections is determined, the number of test wheel assemblies can be connected in parallel through the connection structure, and vertical test assemblies can be connected on both sides of the test wheel assembly sequence. The vertical test assembly includes a laser rangefinder that can emit laser vertically downward to measure the distance between the laser rangefinder and the plane of the area to be tested below. During the advancement of the test wheel assembly sequence, the distance between the laser rangefinders on both sides of the test wheel assembly sequence and the plane of the area to be tested below can be made equal and remain unchanged, so that during the advancement process, the test wheel assembly sequence will not tilt (always maintain the initial state), and there will be no height inconsistency on both sides of the test wheel assembly sequence, so that the detected pressure data is more accurate.

[0056] According to one embodiment of the present invention, the vertical test assembly may include two connection structures, a connection structure located on the side wall may be connected to a connection structure of the test wheel assembly, and another connection structure may be connected to a telescopic bracket, and the length of the telescopic bracket may be telescopic, so as to match test wheel assembly sequences of different lengths. After the test wheel assembly sequence and the vertical test assembly are integrally mounted on the telescopic bracket, the test wheel assembly sequence may be moved forward as a whole by pushing the telescopic bracket, thereby improving the movement consistency of the test wheel assembly sequence.

[0057] According to one embodiment of the present invention, in step S103, the telescopic bracket is placed on the plane of the area to be tested, and the angle between the test wheel assembly sequence and the plane of the area to be tested is adjusted so that the initial distance data measured by the laser rangefinders of the two vertical test assemblies are the same, and the initial pressure data of each pressure sensor is read through the controller. If the initial distance data is the same, it means that the heights of both sides of the test wheel assembly sequence are consistent, and there is no tilting at one end. The initial pressure data is caused by the self-weight of the test wheel assembly sequence, and the pressure data detected by the pressure sensors of each test wheel assembly is theoretically consistent.

[0058] According to one embodiment of the present invention, in step S104, the telescopic bracket can be pushed forward, so that the test wheel assembly sequence can be moved forward as a whole. During the forward process, the distance measured by the laser rangefinder of the vertical test assembly maintains the initial distance data, that is, the test wheel assembly sequence will not tilt (always maintain the initial state), thereby improving the detection accuracy and avoiding the misjudgment of the concave and convex conditions caused by the inclination of the test wheel assembly. When a test wheel assembly passes by a concave and convex position, the height of the entire test wheel assembly sequence can also be kept unchanged, and only the spring assembly of the test wheel assembly passing by the concave and convex position is compressed, so that it detects accurate pressure data.

[0059] According to one embodiment of the present invention, in step S105, at multiple moments in the forward process, the pressure data detected by the pressure sensors of each test wheel assembly can be read by the controller. The time interval between adjacent moments can be 1 second, 2 seconds, etc., and the present invention does not limit this. The forward speed is a preset speed. In the example, the preset speed is 1 cm / second and the time interval is 1 second. Then, in the forward direction, every 1 cm, the pressure data collected by multiple test wheel assemblies can be obtained.

[0060] According to one embodiment of the present invention, in step S106, each time the test wheel assembly sequence advances, the area of ​​the area swept by the test wheel assembly sequence is the product of the length of the test wheel assembly sequence and the length of the area to be tested. The area swept by a single advance cannot cover the entire area to be tested. Therefore, the above-mentioned advance process can be performed multiple times until the area swept by the test wheel assembly sequence can cover the area to be tested, that is, the data collection process in the flatness detection of the area to be tested is completed. The controller analyzes all the collected pressure data to determine the flatness of the area to be tested.

[0061] According to one embodiment of the present invention, in step S107, the flatness detection score of the area to be tested is determined according to the number of executions of the forward process, the preset speed, the pressure data and the initial pressure data, including: determining abnormal pressure data and the abnormal moment corresponding to the abnormal pressure data according to the number of executions, the pressure data, the initial pressure data and the moment corresponding to the pressure data; determining the abnormal detection position corresponding to the abnormal pressure data according to the number of executions, the preset speed and the abnormal moment; determining the flatness detection score of the area to be tested according to the abnormal pressure data and the abnormal detection position.

[0062] According to an embodiment of the present invention, determining abnormal pressure data and the abnormal time corresponding to the abnormal pressure data according to the execution times, the pressure data, the initial pressure data and the time corresponding to the pressure data includes: determining the abnormal time judgment condition according to formula (2): ,

[0063] (2)

[0064] in, is the pressure data detected by the pressure sensor of the kth test wheel assembly in the test wheel assembly sequence at the jth moment during the i-th forward execution, is the initial pressure data, is the first preset proportional coefficient; if the pressure data detected by the pressure sensor of the kth test wheel assembly in the test wheel assembly sequence at the jth moment in the i-th execution of the forward process meets the abnormal moment judgment condition, then the pressure data detected by the pressure sensor of the kth test wheel assembly in the test wheel assembly sequence at the j-th moment in the i-th execution of the forward process is determined as abnormal pressure data, and the j-th moment in the i-th execution of the forward process is determined as the abnormal moment.

[0065] According to one embodiment of the present invention, the abnormal moment judgment condition of formula (2) indicates that if at the jth moment in the i-th forward process, there is a relative deviation between the pressure data detected by the pressure sensor of at least one test wheel assembly in the test wheel assembly sequence and the initial pressure data is greater than or equal to the first preset proportional coefficient, that is, the compression amplitude of the spring assembly has changed significantly, and the test wheel assembly passes through an uneven position, then the pressure sensor detects abnormal pressure data, and the position of the pressure sensor at this time is the abnormal detection position, and the moment (that is, the jth moment in the i-th forward process) is the abnormal moment.

[0066] In this way, the relative deviation between the pressure data detected by the pressure sensors of each test wheel assembly at multiple moments and the initial pressure data can be used to determine whether the test wheel assembly has passed through uneven surfaces, and whether the pressure sensor has detected abnormal pressure data, thereby accurately determining the abnormal moment and providing an accurate data basis for subsequent determination of the abnormal detection position and determination of the flatness detection score.

[0067] According to an embodiment of the present invention, the number of executions, the preset speed, and the abnormal moment determine the abnormal detection position corresponding to the abnormal pressure data, including: if at the jth moment in the i-th execution process, the pressure data detected by the pressure sensor of the k-th test wheel assembly in the test wheel assembly sequence is abnormal pressure data, then determine the abnormal detection position corresponding to the abnormal pressure data according to formula (3) ,

[0068] (3)

[0069] in, is the width of the vertical test component, is the number of connections of the test wheel assembly, is the distance between the rollers of two adjacent test wheel assemblies, is the preset speed, is the time interval between adjacent moments.

[0070] According to one embodiment of the present invention, with the width direction as the X direction, if at the jth moment in the i-th forward process, the pressure data detected by the pressure sensor of the k-th test wheel assembly in the test wheel assembly sequence is abnormal pressure data, then its X-axis coordinate is , where the vertical test assembly is close to the wall during the first advance, so that it cannot be detected within its width range, and the distance in the X direction between the test wheel of the first test wheel assembly and the vertical test assembly is , therefore, the X-axis coordinate of the first test wheel assembly when moving forward for the first time is On this basis, the X-axis coordinate of a test wheel component in a subsequent forward process can be determined.

[0071] According to one embodiment of the present invention, if at the jth moment during the i-th forward execution, the pressure data detected by the pressure sensor of the k-th test wheel assembly in the test wheel assembly sequence is abnormal pressure data, at this time, the test wheel assembly sequence has completed i-1 forwards, and therefore has moved as a whole in the X-axis direction. And the distance between the kth test wheel assembly and the first test wheel assembly in the X-axis direction is Therefore, by adding the above distances in the X-axis direction, the X-axis coordinate of the k-th test wheel assembly during the i-th forward execution can be determined.

[0072] According to one embodiment of the present invention, the difference between the jth moment and the first moment is moments, and at the first moment, the Y-axis coordinate of the test wheel component sequence is 0. Therefore, the Y-axis coordinates of all test wheel components in the test wheel component sequence at the jth moment are , that is, the Y-axis coordinate of the kth test wheel component in the test wheel component sequence is At the jth moment in the i-th execution process, the coordinates of the kth test wheel component in the test wheel component sequence are the coordinates of the abnormality detection position. .

[0073] In this way, when determining the abnormal detection position, the influence of the width of the vertical test assembly and the distance between the test wheel and the vertical test assembly can be considered, and the corresponding abnormal detection position with uneven conditions when abnormal pressure data is detected can be determined through data such as the number of executions and time points of the forward process, thereby improving the accuracy of the abnormal detection position.

[0074] According to an embodiment of the present invention, determining the flatness detection score of the area to be tested based on the abnormal pressure data and the abnormal detection position includes: if the distance between the two abnormal detection positions is less than or equal to , then the two anomaly detection locations are determined as anomaly detection locations within the same anomaly connected domain, where is the distance between the rollers of two adjacent test wheel assemblies, is the preset speed, is the time interval between adjacent moments; traverse all abnormal detection positions to determine the abnormal connected domain in the area to be tested; and determine the flatness detection score of the area to be tested based on the abnormal pressure data of the abnormal detection positions in each abnormal connected domain.

[0075] According to one embodiment of the present invention, the spacing distance between two adjacent test wheel assemblies in the X direction is Therefore, the interval distance between two adjacent abnormal detection positions in the X direction is The time interval between two adjacent moments is Therefore, the interval distance between two adjacent abnormal detection positions in the Y direction is Therefore, the distance between two adjacent abnormal detection positions in the diagonal direction is Therefore, if the distance between two anomaly detection locations is less than or equal to , then the two abnormal detection positions are considered to be adjacent and belong to the same abnormal connected domain. The above distance can be used as the condition for connected domain search to determine all abnormal connected domains in the area to be tested. The abnormal connected domain is not necessarily a rectangular area, and its shape may be irregular.

[0076] According to an embodiment of the present invention, the flatness detection score of the area to be tested is determined according to the abnormal pressure data of the abnormal detection position in each abnormal connected domain, including: determining the flatness detection score of the area to be tested according to formula (4): ,

[0077] (4)

[0078] in, is the number of abnormal detection positions in the hth abnormal connected domain, M is the number of abnormal connected domains, N is the total number of pressure data, is the abnormal pressure data of the abnormal detection position in the sth column and the tth row in the hth abnormal connected domain, is the initial pressure data, is the abnormal pressure data of the abnormal detection position in the s+1th column and the tth row in the hth abnormal connected domain, is the abnormal pressure data of the abnormal detection position in the sth column and the t+1th row in the hth abnormal connected domain, is the abnormal pressure data of the abnormal detection position in the s+1th column and the t+1th row in the hth abnormal connected domain, is the abnormal pressure data of the abnormal detection position in the s+1th column and t-1th row in the hth abnormal connected domain. max is the maximum value function. s, t, h and M are all positive integers.

[0079] According to one embodiment of the present invention, The maximum value of the relative deviation between the abnormal pressure data of multiple abnormal detection positions in the hth abnormal connected domain and the initial pressure data can represent the maximum concavity of the abnormal connected domain. The larger the maximum concavity, the worse the flatness and the more difficult it is to repair.

[0080] According to one embodiment of the present invention, Represents the rate of change of abnormal pressure data between adjacent abnormal detection positions in h abnormal connected domains. Since the abnormal connected domain may not be a rectangle, for a certain abnormal detection position (for example, the abnormal detection position of the sth column and the tth row in the hth abnormal connected domain), its adjacent abnormal detection positions of the s+1th column and the tth row, the abnormal detection position of the sth column and the t+1th row, the abnormal detection position of the s+1th column and the t+1th row, and the abnormal detection position of the s+1th column and the t-1th row may not all exist. Therefore, for a certain abnormal detection position, the above four change rates may not all exist, and the values ​​of the non-existent change rates can be set to 0. Among the above four change rates, the distance between the abnormal detection position of the s+1th column and the tth row and the abnormal detection position of the sth column and the tth row is , therefore, the change rate of the abnormal pressure data between two abnormal detection locations is The distance between the abnormal detection position in the sth column and the t+1th row and the abnormal detection position in the sth column and the tth row is , therefore, the change rate of the abnormal pressure data between two abnormal detection locations is The distance between the abnormal detection position in the s+1th column and the t+1th row and the abnormal detection position in the sth column and the tth row is , therefore, the change rate of the abnormal pressure data between two abnormal detection locations is The distance between the abnormal detection position in the s+1th column and the t-1th row and the abnormal detection position in the sth column and the tth row is , therefore, the change rate of the abnormal pressure data between two abnormal detection locations is For each abnormal detection position, the maximum value of the above four change rates can be taken as the corresponding maximum concave-convex change rate of the abnormal detection position, and the maximum value of the maximum concave-convex change rate of each abnormal detection position can be taken as the maximum value of the concave-convex change rate in the abnormal connected domain. The larger the maximum value of the concave-convex change rate, the more serious the concave-convex change and the worse the flatness.

[0081] According to an embodiment of the present invention, the above-mentioned item representing the maximum concavity and convexity degree and the item representing the maximum value of the concavity and convexity change rate can be weighted and summed to represent the severity of the concavity and convexity condition of the abnormal connected domain. Further, N is the total number of pressure data, which is also the total number of all detection positions where pressure data is obtained. It is the ratio of the number of abnormal detection positions in the h-th abnormal connected domain to the total number of all detection positions, which can represent the size of the h-th abnormal connected domain, that is, the more abnormal detection positions there are in the h-th abnormal connected domain, the larger the area of ​​the abnormal connected domain, and the greater the impact on the flatness of the area to be tested. It can be used as the weight of the severity of the concave-convex condition of the h-th abnormal connected domain. Based on the weight, the severity of the concave-convex condition of all abnormal connected domains in the area to be tested can be weighted and summed to obtain the flatness detection score of the area to be tested, which can represent the overall concave-convex severity of the area to be tested, and can also represent the overall flatness of the area to be tested. The higher the flatness detection score, the lower the overall flatness of the area to be tested.

[0082] In this way, the severity of the unevenness of the abnormal connected domain can be reflected by the maximum unevenness degree and the severity of the unevenness change of the abnormal connected domain, and the influence of the abnormal connected domain on the flatness of the area to be tested can be determined by the number of abnormal detection positions in the abnormal connected domain, so as to obtain the flatness detection score of the area to be tested, so that the flatness detection score of the area to be tested can accurately and objectively express the overall flatness of the area to be tested.

[0083] According to one embodiment of the present invention, in step S108, the flatness quality status of interior decoration can be determined according to the flatness detection scores of multiple areas to be tested. For example, the flatness detection scores of all planes in the room can be determined, and the weight of each plane can be determined based on the area of ​​each plane, and the flatness detection scores of each plane are weighted and summed based on the weight to obtain the interior decoration flatness score, which can reflect the interior decoration flatness quality status, that is, the higher the interior decoration flatness score, the worse the interior decoration flatness quality status, and the higher the severity of the unevenness.

[0084] According to the indoor decoration flatness detection method of the embodiment of the present invention, the number of connections of the test wheel assembly can be determined based on the size of the area to be tested, and the independent detachable test wheel assembly is used to connect according to the number of connections. The size of the test wheel assembly sequence can be flexibly adjusted based on the size of the area to be tested, thereby improving the adaptability to the areas to be tested of different sizes. And the vertical relationship between the test wheel assembly sequence and the plane of the area to be tested can be tested by the vertical test assembly to improve the detection accuracy. Further, the action of the roller when the test wheel assembly encounters a concave and convex position can be converted into pressure data through the combination of a spring assembly and a pressure sensor, thereby intuitively and easily detecting the degree of concave and convex positions of the concave and convex positions. For concave and convex positions with a small degree of concave and convexity that are not easy to detect by size measurement, accurate detection can also be performed, thereby improving the comprehensiveness and accuracy of the flatness detection. When determining the number of connections of the test wheel assembly, a minimum number of connections can be set to avoid the problem that when the area of ​​the concave area is large and the degree of concave is small, the test wheel assembly sequence is all located in the concave area and the change of pressure data cannot be measured. The width of the vertical test assembly is considered when calculating the number of connections of the test wheel assembly to improve the accuracy of the number of connections of the test wheel assembly and improve the adaptability to the test areas of different sizes. When determining the abnormal moment, the relative deviation between the pressure data detected by the pressure sensor of each test wheel assembly at multiple moments and the initial pressure data can be used to determine whether the test wheel assembly passes through the unevenness and whether the pressure sensor detects abnormal pressure data, so as to accurately determine the abnormal moment, and provide an accurate data basis for the subsequent determination of the abnormal detection position and the determination of the flatness detection score. When determining the abnormal detection position, the influence of the width of the vertical test assembly and the distance between the test wheel and the vertical test assembly is considered, and the corresponding abnormal detection position with uneven conditions when the abnormal pressure data is detected is determined by the number of executions of the forward process, the number of moments and other data, so as to improve the accuracy of the abnormal detection position. When determining the flatness detection score, the severity of the unevenness of the abnormal connected domain can be reflected by the maximum unevenness degree of the abnormal connected domain and the severity of the unevenness change, and the influence of the abnormal connected domain on the flatness of the area to be tested can be determined by the number of abnormal detection positions in the abnormal connected domain, thereby obtaining the flatness detection score of the area to be tested, so that the flatness detection score of the area to be tested can accurately and objectively express the overall flatness of the area to be tested.
