TECHNICAL FIELD

[0001] The present application relates to the field of asphalt detection technology, in particular to an asphalt penetration detection method, system, intelligent terminal and storage medium. BACKGROUND

[0002] The asphalt penetration is one of the main quality indicators of asphalt, which represents the softness and hardness of asphalt, the ability to resist shear failure, and reflects the relative viscosity of asphalt under certain conditions. The depth of a standard cone penetrating into the asphalt sample under a load of 100 grams within 5 seconds at 25 degrees Celsius is the penetration, which is measured in tenths of a millimeter.

[0003] In related technology, the asphalt sample is placed in a constant-temperature water tank, and the water tank containing the asphalt sample is placed under the penetration tester. The personnel adjust the standard needle to make the standard needle contact the surface of the asphalt sample, and reset the displacement meter to zero. After adjustment, press the release key, the standard needle falls into the sample and the timing starts at the same time, and stops automatically at 5 seconds. The reading of the displacement meter is the penetration. After testing at one point of the asphalt sample, the personnel adjust the position of the standard needle to test other points of the asphalt sample. Finally, the average value of the results of multiple tests is obtained.

[0004] In the related technology described above, after testing at one test point of the asphalt sample, the personnel manually adjust the position of the standard needle according to the requirements of the test point to make the standard needle aim at another test point of the asphalt sample for testing. The selection of the test point by the personnel is usually based on experience. After selecting the test point, the distance between the test points is measured using a measuring instrument.

[0084] With reference to Figure 1 , the embodiment of the application discloses an asphalt penetration detection method, which comprises the following steps:

[0085] Step S100: obtaining preset preparation completion trigger information of an asphalt sample.

[0086] The asphalt sample refers to a sample prepared by a person skilled in the art according to the national standard of the asphalt penetration detection, including a constant-temperature water tank and a sample dish, the asphalt is placed in the sample dish, the sample dish is placed in the constant-temperature water tank for heat preservation, the asphalt samples belong to the same batch of asphalt, and the preparation process of the asphalt sample is not described herein. The preparation completion trigger information refers to trigger data of uniform and horizontal placement of the asphalt sample, and a specific acquisition method is referred to the steps of the application. Figure 3

[0087] Step S101: obtaining test point information and distribution angle information of the asphalt sample based on the preparation completion trigger information.

[0088] ​The test point information refers to the angle for conducting penetration test on the first asphalt sample, the center point of the asphalt sample is 0 degree, the test point information can be any angle within the angle range of the asphalt sample, for example, 5 degrees, etc., which is determined by the person skilled in the art when initially adjusting the penetration tester device. The distribution angle information refers to the circumferential distribution angle of all the asphalt samples, the angle of the first asphalt sample is 0 degree, if there are totally four asphalt samples, the angles of the remaining three asphalt samples are 90 degrees, 180 degrees and 270 degrees respectively.

[0089] Step S102: controlling the preset penetration tester device to conduct penetration test on the test point information of the asphalt sample.

[0090] The penetration tester device refers to a device for conducting penetration test on the asphalt sample, which comprises a penetration tester and a turntable, the penetration tester is installed on the turntable, and the turntable rotates around the asphalt sample, so that the penetration tester conducts test on different asphalt samples.

[0091] After the test point information is determined, the turntable in the penetration tester device is controlled to rotate the penetration tester to the angle corresponding to the test point information, so that the penetration test is conducted according to the national standard, and the specific method is referred to the steps of Figure 5

[0092] Step S103: acquiring detection completion trigger information.

[0093] The detection completion trigger information refers to the trigger data for completing the penetration test on the first asphalt sample by the penetration tester device, which is output after the penetration test on the asphalt sample is completed.

[0094] Step S104: based on the detection completion trigger information, controlling the penetration tester device to rotate to update the test point information according to the distribution angle information, and controlling the penetration tester device to conduct penetration test on the test point information of the asphalt sample again.

[0095] When the detection completion trigger information is detected, that is, the penetration test on the first asphalt sample is completed by the penetration tester device, a plurality of comparative tests need to be conducted, therefore, the penetration tester is controlled to rotate to other asphalt samples according to the distribution angle information, so as to update the test point information, the specific method is referred to the steps of Figure 2 , and the penetration tester device is controlled to conduct penetration test on the updated test point information again.

[0096] Referring to Figure 2 , the method for controlling the penetration tester device to rotate to update the test point information according to the distribution angle information comprises the following steps:

[0097] ​Step S200: based on the detection completion trigger information, controlling the penetration tester device to rotate according to the distribution angle information, and obtaining the rotation angle information of the penetration tester device.

[0098] Wherein, after detecting the detection completion trigger information, i.e. the penetration tester device completes the penetration detection of the first asphalt sample, the penetration tester device is controlled to rotate to other distribution angle information, and the rotation angle information is detected to provide data support for subsequent determination of new test point information.

[0099] The rotation angle information refers to the angle value of the rotation of the penetration tester device to the next asphalt sample, which is detected by the angle sensor.

[0100] Step S201: determining whether the rotation angle information meets the requirement of the distribution angle information.

[0101] Wherein, the requirement of the distribution angle information refers to the angle difference between the angles corresponding to the distribution angle information, for example, when the distribution angle is 0, 90, 180 and 270 degrees, the requirement is equal to 90 degrees. By judging whether the rotation angle information is equal to the angle difference between the angles corresponding to the distribution angle information, it is determined whether the penetration tester device is rotated to the next asphalt sample.

[0102] Step S2011: if not, continue to control the penetration tester device to rotate according to the distribution angle information, and obtain the rotation angle information for cyclic judgment.

[0103] Wherein, if the rotation angle information is not equal to the angle difference between the angles corresponding to the distribution angle information, it indicates that the penetration tester device has not been rotated to the next asphalt sample, so the penetration tester device is controlled to rotate to other distribution angle information, and the rotation angle information is continuously detected for cyclic judgment.

[0104] Step S2012: if it meets, obtaining the pause angle information, and defining the pause angle information as the updated test point information.

[0105] Wherein, if the rotation angle information is equal to the angle difference between the angles corresponding to the distribution angle information, it indicates that the penetration tester device has been rotated to the next asphalt sample, so the pause angle information is detected to determine that the pause angle information is the test point information.

[0106] The pause angle information refers to the angle of the standard needle in the penetration tester device when the rotation angle information is equal to the angle difference between the angles corresponding to the distribution angle information, which is obtained by the processing terminal according to the angle corresponding to the last test point information plus the rotation angle information, for example, the angle corresponding to the last test point information is 5 degrees, and the rotation angle information is 90 degrees, so the pause angle information is 95 degrees, and the updated test point information is 95 degrees.

[0107] Refer to Figure 3 The method for obtaining the preparation completion trigger information of the preset asphalt sample comprises the following steps:

[0108] Step S300: Obtain placement trigger information of the preset distribution device.

[0109] The distribution device refers to a device for uniformly separating the asphalt sample, comprising a plurality of motors, a rotating rod and a fixed table. The rotating rod is vertically installed at the output end of the motor. The asphalt sample is fixed on the fixed table, and the fixed table is installed at the end of the rotating rod away from the motor, so that the motor drives the asphalt sample to rotate to uniformly distribute the asphalt sample.

[0110] The placement trigger information refers to the trigger data of the asphalt sample placed on the fixed table of the distribution device, which is detected and output by the force sensor on the fixed table.

[0111] Step S301: Obtain the placement number information of the asphalt sample based on the placement trigger information.

[0112] After detecting the placement trigger information, i.e. the personnel places the asphalt sample on the fixed table of the distribution device, the placement number information of the asphalt sample is detected, thereby providing data support for subsequent control of the distribution device to uniformly separate the asphalt sample.

[0113] The placement number information refers to the number of asphalt samples placed on the distribution device, which is obtained by counting the number of received placement trigger information by the processing terminal.

[0114] Step S302: Analyze the placement number information and the preset circumferential angle information to determine the placement angle information of the asphalt sample.

[0115] The circumferential angle information refers to the angle of a circle, i.e. 360 degrees. The placement angle information refers to the interval angle value between adjacent asphalt samples, which is obtained by calculating the quotient between the circumferential angle information and the placement number information by the processing terminal. For example, if the placement number information is 4, the placement angle information is 90 degrees.

[0116] Step S303: Control the distribution device to uniformly separate the asphalt sample according to the placement angle information, and obtain the distribution completion trigger information.

[0117] After determining the placement angle information, the distribution device is controlled to uniformly separate the asphalt sample according to the interval angle corresponding to the placement angle information, and the distribution completion trigger information is detected to provide data support for subsequent determination of whether to output the preparation completion trigger information.

[0118] The distribution completion trigger information refers to trigger data output by an angle sensor when the angle of the distribution device separating the asphalt sample according to the placement angle information is determined to be equal to the placement angle information.

[0119] Step S304: Analyzing the distribution completion trigger information to output the preparation completion trigger information.

[0120] In the step of determining the distribution completion trigger information, i.e., after the distribution device separates the asphalt sample according to the placement angle information, the distribution device is controlled to adjust the asphalt sample according to the distribution trigger information. For details, refer to Figure 4 After the adjustment is completed, the preparation completion trigger information is output.

[0121] For details, refer to Figure 4 The method of analyzing the distribution completion trigger information to output the preparation completion trigger information includes the following steps:

[0122] Step S400: Based on the distribution completion trigger information, control the preset horizontal detection device to rotate at the placement angle information, and obtain the rotated angle information of the horizontal detection device.

[0123] In the step of detecting the distribution completion trigger information, i.e., after the distribution device separates the asphalt sample according to the placement angle information, the horizontal detection device is controlled to rotate at the placement angle information, and the rotated angle information of the horizontal detection device is detected, providing data support for subsequent control of the horizontal detection device to detect the horizontal placement of the asphalt sample.

[0124] The horizontal detection device refers to a device for detecting whether the asphalt sample is placed horizontally on the fixed table of the distribution device, including a motor and a camera. The camera is installed on the output shaft of the motor, so that the motor controls the rotation of the camera to take pictures of the asphalt sample. The rotated angle information refers to the angle value of the rotation of the camera controlled by the motor in the horizontal detection device, which is detected by an angle sensor and sent to a processing terminal.

[0125] Step S401: When the rotated angle information is equal to the placement angle information, control the horizontal detection device to obtain the placement image information of the asphalt sample.

[0126] In the step of determining that the angle corresponding to the rotated angle information is equal to the angle corresponding to the placement angle information in the processing terminal, it indicates that the motor in the horizontal detection device rotates the camera to correspond to the asphalt sample, so that the camera in the horizontal detection device detects the placement image information of the asphalt sample, providing data support for subsequent determination of whether the asphalt sample is placed horizontally.

[0127] The placement image information refers to the image obtained by the horizontal detection device shooting the level installed on the constant-temperature water tank containing asphalt.

[0128] Step S402: Analyze the placement image information to determine the horizontal angle information of the asphalt sample.

[0129] The horizontal angle information refers to the horizontal angle value of the asphalt sample placed on the fixed table of the distribution device, which is obtained by image recognition by the processing terminal according to the placement image information.

[0130] Step S403: Determine whether the horizontal angle information meets the requirements of the reference horizontal angle information.

[0131] The reference horizontal angle information refers to the horizontal angle of the asphalt sample placed on the fixed table of the distribution device, which is 0 degrees. The requirements of the reference horizontal angle information refer to the angle value corresponding to the reference horizontal angle information.

[0132] By determining whether the angle value corresponding to the horizontal angle information is equal to the angle value corresponding to the reference horizontal angle information, it is determined whether the asphalt sample is placed horizontally on the fixed table of the distribution device.

[0133] Step S4031: If not, control the distribution device to adjust the horizontal angle information of the asphalt sample according to the horizontal angle information and the reference horizontal angle information, and continue to obtain the horizontal angle information for cyclic judgment.

[0134] If the angle value corresponding to the horizontal angle information is not equal to the angle value corresponding to the reference horizontal angle information, it indicates that the asphalt sample is not placed horizontally on the fixed table of the distribution device. Therefore, the difference between the horizontal angle information and the reference horizontal angle information is calculated to obtain the adjustment angle, and the fixed table of the distribution device is controlled to adjust the horizontal angle of the asphalt sample according to the adjustment angle, and the horizontal angle information is continuously detected to continuously determine whether the asphalt sample is placed horizontally.

[0135] Step S4032: If it is met, obtain the horizontal placement number information.

[0136] If the angle value corresponding to the horizontal angle information is equal to the angle value corresponding to the reference horizontal angle information, it indicates that the asphalt sample is placed horizontally on the fixed table of the distribution device. Therefore, the horizontal placement number information of the asphalt sample is detected to provide data support for subsequent determination of whether all asphalt samples are placed horizontally. The horizontal placement number information refers to the number of asphalt samples placed horizontally, which is counted by the processing terminal when the horizontal angle information is equal to the reference horizontal angle information.

[0137] Step S404: Determine whether the horizontal placement number information is equal to the placement number information.

[0138] If the number corresponding to the horizontal placement number information is not equal to the number corresponding to the placement number information, it indicates that the asphalt sample is not placed horizontally, and therefore the distribution device is controlled to continue adjusting the horizontal angle information of the asphalt sample, so that all the asphalt samples are placed horizontally.

[0139] Step S4041: If not equal, the distribution device is controlled to continue adjusting the horizontal angle information of the asphalt sample.

[0140] If the number corresponding to the horizontal placement number information is not equal to the number corresponding to the placement number information, it indicates that the asphalt sample is not placed horizontally, and therefore the distribution device is controlled to continue adjusting the horizontal angle information of the asphalt sample, so that all the asphalt samples are placed horizontally.

[0141] Step S4042: If equal, output the preparation completion trigger information.

[0142] If the number corresponding to the horizontal placement number information is equal to the number corresponding to the placement number information, it indicates that the asphalt sample is placed horizontally, and therefore the preparation completion trigger information is output.

[0143] Referring to Figure 5 , the method for controlling the penetration tester device to detect the test point information of the asphalt sample includes the following steps:

[0144] Step S500: Control the penetration tester device to approach the test point information of the asphalt sample along the preset gravity direction information.

[0145] The gravity direction information refers to the direction of gravity. When the penetration tester device is rotated to the angle corresponding to the test point information of the asphalt sample, the standard needle on the penetration tester device is controlled to approach the test point corresponding to the test point information of the asphalt sample along the direction corresponding to the gravity direction information. For specific methods, refer to the steps of Figure 6 , so as to start the penetration detection.

[0146] Step S501: Obtain the asphalt surface contact information of the test point information.

[0147] The asphalt surface contact information refers to the trigger data when the standard needle in the penetration tester device contacts the asphalt surface. The processing terminal outputs after determining that the distance of the standard needle deep into the water at the water surface is equal to the distance between the asphalt surface and the water surface.

[0148] Step S502: Based on the asphalt surface contact information, obtain the test parameter information of the asphalt sample.

[0149] Wherein, in the detection of the asphalt surface contact information, i.e. the standard needle in the needle penetrometer device contacts the surface of the asphalt sample, the test parameter information is detected to provide data support for the subsequent control of the needle penetrometer device detection. The test parameter information refers to the opening information and the detection time length of the needle penetrometer device for detecting the asphalt sample, and the detection time length is usually 5 seconds.

[0150] Step S503: According to the test parameter information, the needle penetrometer device detects the test point information of the asphalt sample.

[0151] Wherein, after determining the test parameter information, the standard needle in the needle penetrometer device enters the asphalt sample within the detection time corresponding to the test parameter information according to the opening information corresponding to the test parameter information, so as to obtain the penetration according to the reading of the displacement meter.

[0152] Reference Figure 6 , the method for controlling the needle penetrometer device to approach the test point information of the asphalt sample along the preset gravity direction information, comprising the following steps:

[0153] Step S600: Obtain the water depth information of the preset water tank.

[0154] Wherein, the water tank refers to a constant temperature water tank for keeping the temperature of the asphalt, the asphalt is placed in a sample dish, the sample dish is placed on the base in the water tank, and the water in the water tank completely submerges the sample dish, so as to keep the asphalt warm. The water depth information refers to the water depth in the constant temperature water tank containing the asphalt, which is detected by the water level sensor after the asphalt sample is placed on the base in the water tank and sent to the processing terminal.

[0155] Step S601: Analyze the water depth information and the preset base height information to determine the containing depth information.

[0156] Wherein, the base height information refers to the height value of the base in the water tank for supporting the sample dish, which is determined by the person skilled in the art in advance and input into the processing terminal. The containing depth information refers to the distance from the base surface to the water surface, which is obtained by calculating the difference between the water depth information and the base height information by the processing terminal.

[0157] Step S602: Obtain the asphalt depth information of the asphalt sample.

[0158] Wherein, the asphalt depth information refers to the depth of the asphalt in the sample dish, including the thickness of the sample dish, which is obtained by the person skilled in the art by checking the scale on the sample dish and input into the processing terminal.

[0159] Step S603: Calculate the difference between the containing depth information and the asphalt depth information, and define the calculated difference as the asphalt contact depth information.

[0160] The asphalt contact depth information refers to the distance value of the standard needle in the penetration meter device from the water surface to the asphalt surface in the water, and the difference between the holding depth information and the asphalt depth information is obtained by the processing terminal.

[0161] Step S604: controlling the penetration meter device to approach the asphalt sample along the gravity direction information, and controlling the preset trigger device to obtain the water surface contact information according to the water depth information.

[0162] The control needle penetration meter device approaches the asphalt sample along the gravity direction information, and the trigger device is controlled to move to the scale corresponding to the water depth information in the water tank to detect the water surface contact information, thereby providing data support for the subsequent control of the penetration meter device to contact the asphalt surface.

[0163] The trigger device refers to a device for detecting the contact of the standard needle in the penetration meter device with the water surface, which can adopt a laser sensing device. The trigger device is controlled to move to the position corresponding to the water depth information in the water tank, so as to detect the movement of the standard needle in the penetration meter device to the water surface. The water surface contact information refers to the trigger data of the contact of the standard needle in the penetration meter device with the water surface, which is output after the standard needle is detected by the trigger device.

[0164] Step S605: based on the water surface contact information, controlling the penetration meter device to move the asphalt contact depth information along the gravity direction information to contact the test point information.

[0165] When the water surface contact information is detected, that is, the standard needle in the penetration meter device contacts the water surface, the penetration meter device is controlled to move the distance value corresponding to the asphalt contact depth information along the gravity direction information, so that the standard needle moves from the water surface to the asphalt surface, so as to contact the asphalt test position corresponding to the test point information.

[0166] Referring to Figure 7 Before the penetration meter device detects the test point information of the asphalt sample, the method further includes a cleaning method for the penetration meter device, and the specific method includes the following steps:

[0167] Step S700: based on the detection completion trigger information, obtaining the standard needle shape information of the preset standard needle.

[0168] When the detection completion trigger information is detected, that is, the penetration meter device completes the detection of one asphalt sample, the standard needle shape information of the standard needle is detected, so as to determine whether the standard needle can continue to be used.

[0169] The standard needle refers to a detection needle in the penetration meter for inserting into the asphalt to detect the asphalt penetration. The standard needle shape information refers to the shape of the standard needle, which is obtained by shooting and image recognition by the camera.

[0170] Step S701: judging whether the standard needle shape information meets the requirement of the preset reference shape information.

[0171] The reference shape information refers to the perfect shape of the standard needle, which is input by a person skilled in the art to a processing terminal. The requirement of the reference shape information refers to the shape consistent with the reference shape information. By judging whether the shape corresponding to the standard needle shape information is consistent with the shape corresponding to the reference shape information, it is determined whether the standard needle can continue to be used.

[0172] Step S7011: if not, an alarm is prompted.

[0173] If the shape corresponding to the standard needle shape information is inconsistent with the shape corresponding to the reference shape information, it indicates that the standard needle has been deformed during the process of being inserted into the asphalt, and the standard needle cannot continue to perform the penetration test, so an alarm is prompted to enable personnel to replace the standard needle in time.

[0174] Step S7012: if yes, the preset cleaning device is controlled to wrap the standard needle, and the cleaning device is controlled to rotate at a preset rotating speed information to clean the standard needle.

[0175] If the shape corresponding to the standard needle shape information is consistent with the shape corresponding to the reference shape information, it indicates that the standard needle has not been deformed during the process of being inserted into the asphalt, and the standard needle can continue to perform the penetration test, so the cleaning device is controlled to wrap the standard needle, and the cleaning device is controlled to rotate at the rotating speed information, so as to clean the asphalt on the standard needle.

[0176] The cleaning device refers to a device for cleaning the standard needle, which can adopt a motor, a telescopic rod and a sponge. The telescopic rod is installed at the output end of the motor, and the sponge is installed at the output end of the telescopic rod. The sponge is coated with trichloroethylene solvent, so that the telescopic rod controls the sponge to wrap the standard needle, and the motor controls the telescopic rod to drive the sponge to rotate to clean the standard needle. The rotating speed information refers to the speed value of the motor controlling the telescopic rod to drive the sponge to rotate in the cleaning device, and the specific value is set by a person skilled in the art according to the actual situation.

[0177] Step S702: after a preset first cleaning time information, the cleaning device is controlled to move away from the standard needle along a preset gravity direction information, and within a preset second cleaning time information, a preset blowing device is controlled to blow air on the standard needle to dry the standard needle.

[0178] After the first cleaning time information of the cleaning device cleaning the standard needle, the cleaning device is controlled to move away from the standard needle along the gravity direction information, so that the sponge wipes off the impurities on the standard needle, and within the second cleaning time information, the blowing device is controlled to blow air on the standard needle to keep the standard needle dry.

[0179] The first cleaning time information refers to a time value of cleaning the standard needle by the cleaning device, and the specific value is set by the person skilled in the art according to the actual situation. The gravity direction information refers to the direction along the gravity. The second cleaning time information refers to a time value of blowing the standard needle by the blowing device, and the specific value is set by the person skilled in the art according to the actual situation. The blowing device refers to a device for blowing the standard needle, which can be composed of a blowing pipe and a blower.
