Description

Technical Field

[0001] The present application relates to the field of performance testing systems, and in particular to methods, systems, storage media and intelligent terminals for testing the anti-permeability performance of concrete. Background Art

[0002] The impermeability of concrete is an important indicator for evaluating the quality and durability of concrete, and is also a must-check indicator for each engineering quality supervision station to strictly control the quality of concrete. Projects with concrete impermeability requirements: such as hydraulic engineering, port engineering, road and bridge engineering, underground structure engineering, etc. The so-called impermeability refers to the ability of the material used in the structure to resist the penetration of water or other liquid (light oil, heavy oil) media under pressure.

[0003] During the test, a layer of melted sealing material is rolled on the side of the specimen, and then it is immediately pressed into the test mold preheated in an oven or electric furnace on a screw press. The bottom surface of the specimen is flush with the test mold. After the test mold cools down, the pressure can be released and the specimen is installed on the permeameter for testing. Then the water pressure starts from 0.2Mpa, and the water pressure is increased by 0.1Mpa every 8 hours. The end surface of the specimen is observed at any time until 3 out of 6 specimens have water seepage on the surface. The water pressure at this time is recorded and the test can be stopped. When the pressure is increased to the designed anti-seepage mark, the third specimen still does not seep water after 8 hours, indicating that the concrete has met the design requirements and the test can be stopped.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the test process requires the tester to continuously and manually observe the water seepage situation. The long-term observation work consumes a lot of the tester's time and energy, and there is still room for improvement. Summary of the invention

[0005] In order to improve the test process, the tester needs to continuously observe the water seepage manually. The long-term observation work consumes a lot of time and energy of the tester. This application provides a method, system, storage medium and intelligent terminal for testing the anti-seepage performance of concrete.

[0006] In the first aspect, the present application provides a method for testing the anti-permeability performance of concrete, which adopts the following technical solution:

[0007] Concrete impermeability testing methods include:

[0008] After the specimen is placed, the testing instrument moves down to approach the specimen. The testing instrument is clamped with absorbent paper. The absorbent paper is evenly distributed in a fan shape and all the absorbent paper forms a disk. The clamping position is set along the circumference of the absorbent paper.

[0009] Acquire the position information of the absorbent paper above the test piece and the infrared sensing information between the test piece and the absorbent paper;

[0010] Determine whether both the absorbent paper in place information and the infrared sensing information exist;

[0011] If both the absorbent paper in place information and the infrared sensing information exist, the downward movement is stopped and the absorbent paper weight at the current time is obtained, which is defined as the dry weight information;

[0012] If the absorbent paper in place information does not exist but the infrared sensing information exists, continue to move the absorbent paper downwards;

[0013] If the absorbent paper is in place information exists but the infrared sensing information does not exist, the weight on the absorbent paper is obtained and defined as the absorbent gravity information;

[0014] Determine whether the water absorption gravity information is greater than the dry weight information;

[0015] If it is greater than the dry weight information, the penetration information is output;

[0016] Determine whether the number of devices outputting the penetration information exceeds the preset specified number;

[0017] If it is equal to the specified quantity information, then stop working and obtain and output the current water pressure level information;

[0018] If the number of messages is less than the specified number, continue the test;

[0019] If it is equal to the dry weight information, the absorbent paper falling information will be output and the test personnel will be alerted.

[0020] By adopting the above technical solution, the state of the absorbent paper is judged by detecting the information of the device being in place and the device falling, and the change in weight information is used to double judge whether it has penetrated. As a result, more accurate data can be obtained without human operation during the entire test process, avoiding errors in the results obtained by a single judgment, saving manpower and improving the accuracy of the detection.

[0021] Optionally, the penetration information includes sealing ring penetration information and concrete penetration information, and a method for distinguishing the sealing ring penetration information from the concrete penetration information includes:

[0022] Obtaining outer ring weight information and inner ring weight information of a weighing device arranged along the circumference of the test piece;

[0023] Calculate difference information based on the water absorption gravity information and the dry weight information, and define it as water absorption weight information;

[0024] According to the length stored in the preset length database, the outer ring weight information and the inner ring weight information are matched and analyzed to determine the length corresponding to the outer ring weight information and the inner ring weight information, and the length corresponding to the outer ring weight information is defined as the outer ring length information, and the length corresponding to the inner ring weight information is defined as the inner ring length information;

[0025] Calculate the current tilt amplitude information according to the outer circle length information and the inner circle length information;

[0026] According to the tilt amplitude stored in the preset tilt database, a matching analysis is performed with the water absorption weight information to determine the tilt amplitude corresponding to the water absorption weight information, which is defined as the approved tilt amplitude information;

[0027] Determine whether the current tilt amplitude information is greater than the approved tilt amplitude information;

[0028] If it is greater than the approved tilt amplitude information, the sealing ring penetration information and warning information are output;

[0029] If it is less than the approved inclination amplitude information, the concrete penetration information and normal working information are output.

[0030] By adopting the above technical solution, the position where the absorbent paper absorbs water is determined by the characteristics of the absorbent paper and the principle of leverage. Since the amplitude of water absorption at the outer circle boundary is known, the amplitude will increase when the position exceeds the outer circle, so the corresponding water absorption position can be obtained by the rotation amplitude, with high determination accuracy and efficiency, thereby improving the efficiency of machine automated analysis.

[0031] Optionally, the method for locating the location of concrete penetration information includes:

[0032] Obtaining individual infrared sensing information and sensor number information set along the semi-circumference of the test piece, defining the sum of all individual infrared sensing information as infrared sensing information, and defining that when one of the infrared sensors does not receive any induction, the infrared sensing information does not exist;

[0033] Filter out sensor number information for which independent infrared sensing information does not exist, and define it as abnormal sensor number information;

[0034] According to the absorbent paper number and abnormal sensor number information stored in the preset absorbent paper number database, a matching analysis is performed to determine the absorbent paper number corresponding to the abnormal sensor number information, where there are two pieces of absorbent paper corresponding to one sensor, and the piece far away from the sensor is defined as the far absorbent paper number information, and the piece close to the sensor is defined as the near absorbent paper number information;

[0035] Obtain feedback distance information from the abnormal sensor number information;

[0036] Comparing the feedback distance information with the distance corresponding to the preset intermediate distance information;

[0037] If the feedback distance information is greater than the distance corresponding to the intermediate distance information, the far absorbent paper number information and concrete penetration information are output;

[0038] If the feedback distance information is less than the distance corresponding to the intermediate distance information, the near absorbent paper number information and concrete penetration information are output.

[0039] By adopting the above technical solution, if the information of the absorbent paper being in place exists but the infrared sensing information does not exist, the position where the infrared rays are blocked by the absorbent paper after being tilted can be judged by the information of the reflection distance of each infrared ray. The data is relatively accurate and the penetration position can be given for subsequent observation and analysis of the test results, thereby improving the efficiency of machine automated analysis.

[0040] Optionally, a method for determining the information of the absorbent paper being in place is also included, the method comprising:

[0041] Obtain the distance information when each weighing device moves down to the point where both the absorbent paper and infrared sensing information are present, and then continue to move down and obtain the detection value of the load-bearing device in real time, which is defined as the detection weight information;

[0042] Determine whether the detected weight information is equal to the dry weight information;

[0043] If the detected weight information is equal to the dry weight information, continue to move down;

[0044] If the detected weight information is less than the dry weight information, the downward movement distance of the weighing device at this time is obtained and defined as the detected distance information;

[0045] Determine whether all detection distance information is consistent;

[0046] If the detected distance information is consistent, the weighing device moves up to the position corresponding to the distance information and performs detection;

[0047] If the detection distance information is inconsistent, the information about the uneven concrete surface will be output and a warning will be issued.

[0048] By adopting the above technical solution, the distance between the absorbent paper and the upper surface of the concrete is determined by setting the movement of the weighing device, so as to judge whether the concrete test piece is correctly processed and formed or whether it is correctly installed, thereby preventing the occurrence of inaccurate detection due to the test piece itself, and improving the detection accuracy of the detection device.

[0049] Optionally, a method for detecting the state of the absorbent paper is also included, the method comprising:

[0050] Calculate the difference distance information according to the intermediate distance information and the feedback distance information;

[0051] Calculate the actual height information based on the inner circle length information, the current tilt amplitude information and the difference distance information;

[0052] Compare the actual altitude information with the preset horizontal infrared altitude information;

[0053] If the actual height information is inconsistent with the horizontal infrared height information, the absorbent paper softening information is output and an alarm is issued;

[0054] If the actual height information is consistent with the horizontal infrared height information, the concrete penetration information is output normally.

[0055] By adopting the above technical solution, absorbent paper is prone to soften and bend due to the amount of water absorbed, which leads to inaccurate measured position and measured tilt amplitude. Therefore, a detection device for softening absorbent paper is provided to remind the tester to replace absorbent paper with higher hardness to avoid data errors due to softening, thereby improving the detection accuracy and troubleshooting ability of the detection device.

[0056] Optionally, a method for concrete detection is also included, the method comprising:

[0057] Obtain thermal image information corresponding to the detection area corresponding to the number of the absorbent paper;

[0058] Determine whether all thermal image information is consistent;

[0059] If they are consistent, continue testing;

[0060] If there is inconsistency, the thermal image information with a larger number of consistent ones is distinguished and defined as the approved thermal image information, and the thermal image information inconsistent with the approved thermal image information is defined as abnormal thermal image information;

[0061] Obtain the absorbent paper number corresponding to the abnormal thermal image information, and define it as the problematic absorbent paper number information;

[0062] Determine whether the number corresponding to the far absorbent paper number information or the near absorbent paper number information is consistent with the problem absorbent paper number information;

[0063] If they are consistent, the concrete abnormality information is output and the concrete penetration information is not output;

[0064] If they are inconsistent, the far absorbent paper number information or the near absorbent paper number information and the concrete penetration information are output.

[0065] By adopting the above technical solution, it is possible to determine whether there are defects or abnormalities in the concrete through thermal imaging images, and then determine whether the abnormality affects the permeability by locating the abnormal position, thereby reducing the erroneous situation of permeability changes caused by abnormalities in the specimen itself and improving the accuracy of detection by the detection device.

[0066] Optionally, the method of outputting concrete abnormality information includes:

[0067] Obtaining thermal image information corresponding to the far absorbent paper number information or the near absorbent paper number information, and defining it as initial thermal image information;

[0068] Obtain a thermoforming image of the concrete specimen after rotation, and define the thermoforming image as rotational thermal image information;

[0069] Determine whether the initial thermal image information and the rotational thermal image information are consistent;

[0070] If they are consistent, the abnormal information of the detection instrument is output;

[0071] If they are inconsistent, the concrete abnormality information will be output.

[0072] By adopting the above technical solution, the concrete specimen is rotated to determine whether the abnormal image rotates synchronously with the rotation of the concrete specimen, thereby determining whether the cause of the abnormal image is on the concrete itself or on the lower end supporting device, thereby accurately finding the root cause of the abnormal problem and improving the efficiency of solving the abnormal problem.

[0073] In the second aspect, the present application provides a concrete anti-permeability performance detection system, which adopts the following technical solution:

[0074] A concrete anti-permeability testing system, comprising:

[0075] After the specimen is placed, the testing instrument moves down to approach the specimen. The testing instrument is clamped with absorbent paper. The absorbent paper is evenly distributed in a fan shape and all the absorbent paper forms a disk. The clamping position is set along the circumference of the absorbent paper.

[0076] Infrared sensing module, used to obtain the information of the absorbent paper above the test piece and the infrared sensing information between the test piece and the absorbent paper;

[0077] A processing module, connected to the infrared sensing module and the judgment module, for storing and processing information;

[0078] A judgment module, judging whether both the absorbent paper in place information and the infrared sensing information exist;

[0079] A weighing module, connected to the processing module, for obtaining the weight on the absorbent paper;

[0080] If the judging module determines that both the absorbent paper in place information and the infrared sensing information exist, the processing module stops moving down and obtains the absorbent paper weight at the current time, which is defined as the dry weight information;

[0081] If the judging module determines that the absorbent paper is in place information does not exist but the infrared sensing information exists, the processing module continues to move the absorbent paper downward;

[0082] If the judgment module determines that the absorbent paper is in place but the infrared sensing information does not exist, the weighing module obtains the weight on the absorbent paper and defines it as the water absorption gravity information;

[0083] The judging module judges whether the water absorption gravity information is greater than the dry weight information;

[0084] If the judgment module determines that it is greater than the dry weight information, the processing module outputs the penetration information;

[0085] The judging module judges whether the number of devices outputting the penetration information exceeds a preset specified number;

[0086] If the judging module judges that the information is more than the specified amount, the processing module stops working and obtains and outputs the current water pressure level information;

[0087] If the judging module judges that the amount is less than the specified amount, the processing module controls the detection device to continue the test;

[0088] If the judgment module determines that it is equal to the dry weight information, the processing module outputs the absorbent paper falling information and warns the test personnel.

[0089] By adopting the above technical solution, the state of the absorbent paper is judged by detecting the information of the device being in place and the device falling, and the change in weight information is used to double judge whether it has penetrated. As a result, more accurate data can be obtained without human operation during the entire test process, avoiding errors in the results obtained by a single judgment, saving manpower and improving the accuracy of the detection.

[0090] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution:

[0091] An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and execute any one of the above-mentioned concrete impermeability testing methods.

[0092] By adopting the above technical solution, the state of the absorbent paper is judged by detecting the information of the device being in place and the device falling, and the change in weight information is used to double judge whether it has penetrated. As a result, more accurate data can be obtained without human operation during the entire test process, avoiding errors in the results obtained by a single judgment, saving manpower and improving the accuracy of the detection.

[0093] In a fourth aspect, the present application provides a computer-readable storage medium capable of storing corresponding programs and having the characteristics of rapid infrared sensing.

[0094] A computer-readable storage medium adopts the following technical solution:

[0095] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned concrete impermeability testing methods.

[0096] By adopting the above technical solution, the state of the absorbent paper is judged by detecting the information of the device being in place and the device falling, and the change in weight information is used to double judge whether it has penetrated. As a result, more accurate data can be obtained without human operation during the entire test process, avoiding errors in the results obtained by a single judgment, saving manpower and improving the accuracy of the detection.

[0097] In summary, the present application includes at least one of the following beneficial technical effects:

[0098] Through double judgment of penetration, the error of single judgment can be avoided, which saves manpower and improves the accuracy of detection;

[0099] The position of water absorption by the absorbent paper is determined by the characteristics of the absorbent paper and the principle of lever, which has high accuracy and high efficiency, thus improving the efficiency of machine automated analysis.

[0100] By using thermal imaging images to determine whether there are defects or abnormalities in the concrete, the error of changes in permeability due to abnormalities of the specimen itself can be reduced, and the accuracy of detection by the detection device can be improved.

[0110] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0111] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0112] See also Figure 1 The embodiment of the present invention provides a method for detecting the anti-permeability performance of concrete. The main process of the method for detecting the anti-permeability performance of concrete is described as follows:

[0113] Step 100: After the specimen is placed, the testing instrument is moved down close to the specimen. The testing instrument is clamped with absorbent paper. The absorbent paper is evenly distributed in a fan shape and all the absorbent paper forms a disk. The clamping position is set along the circumference of the absorbent paper.

[0114] Detection device such as Figure 2 As shown, the absorbent paper is arranged along the circumference, and all the absorbent paper is clamped by two weighing devices with weight measurement function, which are respectively distributed along the a circle and the b circle. The absorbent paper can rotate around the inner circle, and the clamping column on the outer circle passes through the long waist hole and abuts against the lower side of the absorbent paper. Both can be stretched due to the weight, similar to a tensile gauge. It should be noted that the density of the absorbent paper decreases from the outside to the inside, so that the absorbent paper can remain horizontal when it is on the two weighing devices in a dry state. In order to ensure the absorption rate, calcium carbonate and other ingredients can be coated on the absorbent paper.

[0115] Step 101: Acquire the position information of the absorbent paper located above the test piece and the infrared sensing information between the test piece and the absorbent paper.

[0116] The absorbent paper arrival information refers to the information that the absorbent paper reaches the corresponding position where the water stains on the upper surface of the test piece can be absorbed. At this position, there is a certain distance from the surface of the test piece, but water droplets above the upper surface of the test piece can also be absorbed. The acquisition method can be an infrared sensor. When there is absorbent paper above, the signal receiver at the other end cannot receive the infrared signal and outputs the absorbent paper arrival information to the terminal.

[0117] Infrared sensing information refers to the infrared information received in the gap between the absorbent paper and the upper surface of the specimen when the absorbent paper reaches the position corresponding to the absorbent paper arrival information. Figure 2 It can be seen that infrared sensing information can also be generated by an infrared transmitter, with a corresponding receiving device at the other end. The infrared transmitter is set outside the half circle, and the receiver is set in the opposite interval.

[0118] Step 102: Determine whether both the absorbent paper in place information and the infrared sensing information exist.

[0119] The purpose of the judgment is to determine whether the absorbent paper is in place and whether the absorbent paper moves downward and rotates due to absorbing water.

[0120] Step 1021: If both the absorbent paper in place information and the infrared sensing information exist, stop moving downward and obtain the absorbent paper weight at the current time, which is defined as the dry weight information.

[0121] The dry weight information is the weight information of the absorbent paper in a dry state. Since the absorbent paper is in a water-free state at the beginning, when the absorbent paper in place information is triggered, it means that the absorbent paper is in place, and since the infrared sensing information also exists, the absorbent paper does not fall, that is, the absorbent paper does not absorb water, so this is the dry weight information.

[0122] Step 1022: If the absorbent paper in place information does not exist but the infrared sensing information exists, continue to move the absorbent paper downward.

[0123] There are two situations when the absorbent paper is not in place information: the absorbent paper absorbs water and sinks or the absorbent paper is not in place, and the existence of infrared sensing information indicates that the absorbent paper has not sunk. At this time, it means that it has not yet reached the position corresponding to the absorbent paper in place information, and it is necessary to continue to move down to the specified position for water absorption test.

[0124] Step 1023: If the absorbent paper is in place information exists but the infrared sensing information does not exist, the weight on the absorbent paper is obtained and defined as the absorbent gravity information.

[0125] The water absorption gravity information is the weight of the water absorbed on the absorbent paper. Here, there is an integral weighing device above the entire device, through which the overall mass after water absorption is obtained.

[0126] Step 103: Determine whether the water absorption gravity information is greater than the dry weight information.

[0127] The purpose of the judgment is to determine whether water is absorbed.

[0128] Step 1031: If it is greater than the dry weight information, output the penetration information.

[0129] The penetration information is any information that can be seen and identified by the test personnel, such as a red light. If it is greater than the dry weight information, it means that the absorbent paper has absorbed water, which means that the test piece here has begun to seep water under the current water pressure.

[0130] Step 1032: If it is equal to the dry weight information, output the absorbent paper falling information and alert the test personnel.

[0131] The absorbent paper drop information is information that the absorbent paper has dropped from the weighing device, and it can be any indication information, such as a yellow light. Because the absorbent paper has dropped but has not absorbed water, the possible reason may be external interference and other factors, so the absorbent paper drop information is output to remind the test personnel to check this place.

[0132] Step 104: Determine whether the number of devices outputting the penetration information exceeds a preset specified number.

[0133] The specified quantity information is information about the number of devices that need to have penetration information. In this embodiment, if the number of all test pieces is 6, the specified quantity information is set to 3 in advance. The purpose of the judgment is to determine whether the test has been completed. The specific value is specified in the specification and will not be repeated here.

[0134] Step 1041: If it is equal to the specified quantity information, stop working and obtain and output the current water pressure level information.

[0135] The current water pressure level information is the information of the water pressure level displayed on the water pressure meter of the current water valve, which is actually the content displayed on the dial every time during the pressurization process. The acquisition method can be image reading or internal water pressure detection, such as a water pressure gauge. If it is equal to the specified quantity information, it means that the test is over and the performance test is completed, then the work is stopped at this time, and then the corresponding water pressure level is output. The conversion formula for outputting the anti-seepage level is a conventional calculation formula in this field, which will not be repeated here.

[0136] Step 1042: If the amount is less than the specified amount, continue the test.

[0137] If the number is less than the specified information, it means that the water resistance level has not yet reached the standard requirements, and further testing is required to obtain the corresponding water pressure.

[0138] Reference Figure 3 The penetration information includes sealing ring penetration information and concrete penetration information. The method of distinguishing the sealing ring penetration information from the concrete penetration information includes:

[0139] Step 200: Obtain outer ring weight information and inner ring weight information of a weighing device arranged along the circumference of the specimen.

[0140] The outer ring weight information is the same as the Figure 2 The weight information of the inner circle is the weight information detected by the weighing device on the middle circle b. Figure 2 The weight information detected by the weighing device on the middle a circle. The sum of the outer circle weight information and the inner circle weight information is the total weight information of a piece of absorbent paper. The method of obtaining is the same as that of a tensile gauge, that is, the elongation is the weight.

[0141] Step 201: Calculate difference information based on water absorption gravity information and dry weight information, and define it as water absorption weight information.

[0142] The difference information is the water absorption gravity information, which is calculated as the difference between the water absorption gravity information and the dry weight information. The purpose of obtaining it is to determine how much water is absorbed.

[0143] Step 202: Match and analyze the length stored in the preset length database with the outer ring weight information and the inner ring weight information to determine the length corresponding to the outer ring weight information and the inner ring weight information, define the length corresponding to the outer ring weight information as the outer ring length information, and define the length corresponding to the inner ring weight information as the inner ring length information.

[0144] The outer ring length information is the information of the extended length of the outer ring weighing device. The database stores the mapping relationship between length information and weight information, that is, when the weight information is input, including the outer ring weight information and the inner ring weight information, the system automatically finds the corresponding weight information from the database and outputs it. The database is the result obtained by the staff in this field through a limited number of experiments.

[0145] Step 203: Calculate the current tilt amplitude information according to the outer circle length information and the inner circle length information.

[0146] The current tilt amplitude information is the information of the tilt of the absorbent paper under the current actual situation. The calculation method is tanφ=(L1-L2) / L0, where LI is the outer circle length information, L2 is the inner circle length information, and L0 is the distance information between the two, that is, the diameter difference between the outer circle and the inner circle. When this value is calculated, φ is then output in reverse, which is the current tilt amplitude information.

[0147] Step 204: performing a matching analysis based on the tilt amplitude stored in the preset tilt database and the water absorption weight information to determine the tilt amplitude corresponding to the water absorption weight information, and defining it as the approved tilt amplitude information.

[0148] The approved tilt amplitude information is the information of the tilt amplitude when the moisture of the corresponding water absorption weight information and the water absorption position is on the outer ring. The tilt database stores the mapping relationship between the corresponding water absorption weight information and the tilt amplitude, which is obtained by the staff in this field through experiments. When the corresponding water absorption weight information is calculated, the system automatically retrieves the corresponding tilt amplitude information from the tilt database.

[0149] Step 205: Determine whether the current tilt amplitude information is greater than the approved tilt amplitude information.

[0150] The purpose of the judgment is to determine the location of water absorption. Due to the characteristics of absorbent paper, the water absorption process must start from the water absorption point and spread outwards, and the weight of the water absorption point is the largest, so the location of water absorption can basically be determined.

[0151] Step 2051: If it is greater than the approved tilt amplitude information, the sealing ring penetration information is output and a warning message is output.

[0152] The seal ring penetration information is information that there is a gap between the time and the device, allowing water to penetrate from between the two. Warning information is information that can be identified by test personnel, such as a red light, and insufficient sealing information is indicated under the corresponding light. If it is greater than the approved tilt amplitude information, it means that the tilt is greater. From the principle of levers, we know that the farther the object is from the center of rotation, the greater the effect it produces. This means that the water absorption point is outside the outer circle at this time, and the outside of the outer circle represents the position of the seal ring, which means that the sealing performance is poor at this time, and water penetrates from the gap between the test piece and the device, then the seal ring penetration information and warning information are output.

[0153] Step 2052: If it is less than the approved inclination amplitude information, output the concrete penetration information and output the normal working information.

[0154] Normal working information is information about the normal working of the specimen, which can be any identifiable information, such as a green light. If it is less than the approved tilt amplitude information, it means that the water absorption position is inside the outer circle, and the outer circle is on the specimen, which means that the sealing is good and water is penetrating normally.

[0155] Reference Figure 4 , the location method of concrete penetration information includes:

[0156] Step 300: Obtain individual infrared sensing information and sensor number information set along the semi-circumference of the test piece, define the sum of all individual infrared sensing information as infrared sensing information, and define that when one of the infrared sensors does not receive any induction, the infrared sensing information does not exist.

[0157] The single infrared sensing information is the single infrared sensing information, from the attached Figure 2This has been described in step 101 and will not be repeated here.

[0158] Step 301: Filter out sensor number information for which independent infrared sensing information does not exist, and define it as abnormal sensor number information.

[0159] The abnormal sensor number information is the number information of the sensor for which the independent infrared sensing information does not exist. That is, when the infrared sensing information is not received by the opposite receiver, the number information is output to the intelligent terminal.

[0160] Step 302: Perform a matching analysis based on the absorbent paper numbers and abnormal sensor number information stored in the preset absorbent paper number database to determine the absorbent paper number corresponding to the abnormal sensor number information. Here, there are two pieces of absorbent paper corresponding to one sensor. The piece far away from the sensor is defined as the far absorbent paper number information, and the piece close to the sensor is defined as the near absorbent paper number information.

[0161] The far absorbent paper number information is the number information of the absorbent paper that is farther away from the abnormal sensor number information. The near absorbent paper number information is the number information of the absorbent paper that is closer to the abnormal sensor number information. Since the infrared sensor is only half set, the situation where the infrared ray cannot receive information may be any one of the symmetrical absorbent papers, so there are possible situations. The mapping relationship between the absorbent paper number information and the abnormal sensor number information is stored in the database, which is observed and input by the staff in this field according to the specific situation.

[0162] Step 303: Obtain feedback distance information sent by the abnormal sensor number information.

[0163] The feedback distance information is the distance information of the infrared transmitter corresponding to the abnormal sensor number information after the infrared ray is emitted and reflected. In this device, there is not only a receiver opposite the infrared transmitter, but also a receiver at the same end. If the receiver at the same end receives it, it will output the feedback distance information. The specific acquisition method is any distance measurement method, such as an infrared rangefinder.

[0164] Step 304: Compare the feedback distance information with the distance corresponding to the preset intermediate distance information.

[0165] The intermediate distance information is the distance between the infrared rangefinder and the center of the detection device, which is measured by the staff in this field before the test. The purpose of the comparison is to determine whether the distance measurement position is on the side close to the transmitter or on the side far away from the center.

[0166] Step 3041: If the feedback distance information is greater than the distance corresponding to the intermediate distance information, output the far absorbent paper number information and concrete penetration information.

[0167] If the feedback distance information is greater than the distance corresponding to the middle distance information, it means that the absorbent paper interfering with the infrared rays is on the side far away from the center, and the far absorbent paper number information and concrete penetration information can be output.

[0168] Step 3042: If the feedback distance information is less than the distance corresponding to the intermediate distance information, output the near absorbent paper number information and the concrete penetration information.

[0169] If the feedback distance information is less than the distance corresponding to the middle distance information, it means that the absorbent paper interfering with the infrared rays is on the side close to the center, and the output may be the near absorbent paper number information and the concrete penetration information.

[0170] Reference Figure 5 , and also includes a method for determining the information that the absorbent paper is in place, the method comprising:

[0171] Step 400: Obtain the distance information when each weighing device moves down to the point where both the absorbent paper and infrared sensing information exist, and then continue to move down and obtain the detection value of the load-bearing device in real time, which is defined as the detection weight information.

[0172] The distance information is the distance the weighing device moves down when it moves down to the position corresponding to the absorbent paper in place information. The purpose here is to determine a reference value for verification. The detection weight information is the weight information measured on the weighing device. When the weighing device and the absorbent paper touch the test piece, the weight detected by the weighing device will decrease accordingly. The purpose of obtaining it is to compare with the dry weight information. It should be noted that the method here is the method before the test, that is, it is carried out after the test piece is placed on the instrument and before the impermeability test.

[0173] Step 401: Determine whether the detected weight information is equal to the dry weight information.

[0174] The purpose of the judgment is to determine whether the weighing device touches the test piece during the downward movement.

[0175] Step 4011: If the detected weight information is equal to the dry weight information, continue to move down.

[0176] If the detected weight information is equal to the dry weight information, it means that the detected weight has not changed at this time, which means that it has not reached the destination yet.

[0177] Step 4012: If the detected weight information is less than the dry weight information, the downward movement distance of the weighing device at this time is obtained and defined as the detected distance information.

[0178] The detection distance information is the information of the distance the weighing device moves downward when the detection weight information is less than the dry weight information, and can be obtained by the instrument itself. If the detection weight information is less than the dry weight information, it means that it has reached the test piece at this time, and the detection distance information at this time can be output, in order to determine the distance from the distance information moving downward.

[0179] Step 402: Determine whether all detection distance information is consistent.

[0180] The purpose of the judgment is to determine whether the surface of all the test pieces is a horizontal plane. It should be noted that the lowest end of all the weighing devices is on a horizontal plane during the descent process. The purpose of the judgment is to determine whether it is on a horizontal plane.

[0181] Step 4021: If the detected distance information is consistent, the weighing device moves up to the position corresponding to the distance information and performs detection.

[0182] If the detected distance information is consistent, it means that all weighing devices have moved down the same distance and the distance against the time surface is also the same, which means that the handling method of the specimen itself is correct and can be used normally. Then you can move it to the position corresponding to the absorbent paper in place information to start the test.

[0183] Step 4022: If there is inconsistency in the detection distance information, output information about the uneven concrete surface and issue a warning.

[0184] The information of the uneven concrete surface indicates the surface information of the specimen. If there is inconsistency in the detection distance information, it means that the distance the weighing device moves down is inconsistent, which indirectly indicates that the surface of the specimen is not smooth, and the information of the uneven concrete surface is output and an alarm is given.

[0185] Reference Figure 6 , also includes a method for detecting the state of the absorbent paper, the method comprising:

[0186] Step 500: Calculate difference distance information according to the intermediate distance information and the feedback distance information.

[0187] The difference distance information is information about the difference between the intermediate distance information and the feedback distance information, that is, information about the distance of the light emitted by the center distance infrared transmitter on the absorbent paper.

[0188] Step 501: Calculate actual height information based on the inner circle length information, current tilt amplitude information and difference distance information.

[0189] The actual height information is the height of the light emitted by the infrared transmitter on the absorbent paper. The calculation method is proportional conversion, and the calculation formula is: H=L2+tanφ*ΔL, where ΔL is the difference distance information.

[0190] Step 502: Compare the actual height information with the preset horizontal infrared height information.

[0191] The horizontal infrared height information is the height information of infrared rays emitted by the infrared emitter pre-installed on the detection device for detecting the position of the gap between the absorbent paper and the test piece. The purpose of the comparison is to determine whether the absorbent paper is tilted in a straight line and whether the absorbent paper still maintains its original shape.

[0192] Step 5021: If the actual height information and the horizontal infrared height information are inconsistent, the absorbent paper softening information is output and a warning is issued.

[0193] The absorbent paper softening information refers to the information that the absorbent paper softens after absorbing water and cannot maintain its original shape. If the actual height information and the horizontal infrared height information are inconsistent, it means that the absorbent paper is deformed after being exposed to water. Since it cannot maintain its shape, it needs to be replaced with a more absorbent paper. The warning situation can be in any form, such as text display.

[0194] Step 5022: If the actual height information is consistent with the horizontal infrared height information, the concrete penetration information is output normally.

[0195] If the actual height information is inconsistent with the horizontal infrared height information, it means that the absorbent paper still maintains its original shape, which means that the steps of the previous method still meet the requirements of the method. There is no need to correct or replace the absorbent paper, and it works and outputs normally.

[0196] Reference Figure 7 : Also included is a method for concrete testing, the method comprising:

[0197] Step 600: Obtain thermal image information corresponding to the detection area corresponding to the number of the absorbent paper.

[0198] Thermal imaging information is the information of receiving the thermoforming image above the weighing device. Here, the water below the test piece can be replaced with hot water, which makes it easier to image. The acquisition method is a camera that can receive thermal imaging information, such as an infrared thermal imager.

[0199] Step 601: Determine whether all thermal image information is consistent.

[0200] The purpose of the judgment is to determine whether the concrete conditions at all locations are consistent and thus determine whether the concrete is evenly distributed.

[0201] Step 6011: If they are all consistent, continue testing.

[0202] If they are all consistent, it means that each area is in the same situation, and most of them are in similar situations and are dense, so you can continue testing.

[0203] Step 6012: If there is inconsistency, distinguish the thermal imaging information with a larger number of consistent ones and define them as approved thermal imaging information, and define the thermal imaging information inconsistent with the approved thermal imaging information as abnormal thermal imaging information.

[0204] Approved thermal image information is the thermal image information with the largest number of consistent thermal image information, and those that are inconsistent with the thermal image information are defined as abnormal thermal image information. This is a screening method. Since the standard is still used as the standard when the test piece is artificially made, in actual situations, the standard thermal image information is more, so it is defined as approved thermal image information.

[0205] Step 602: Obtain the absorbent paper number corresponding to the abnormal thermal image information, and define it as the problematic absorbent paper number information.

[0206] The number information of the problematic absorbent paper is the absorbent paper corresponding to the detection area of ​​abnormal thermal image information. The acquisition method may be to search in a number database, that is, the database stores information of the absorbent paper number corresponding to the area corresponding to the abnormal thermal image information.

[0207] Step 603: Determine whether the number corresponding to the far absorbent paper number information or the near absorbent paper number information is consistent with the problem absorbent paper number information.

[0208] The purpose of the judgment is to determine whether the water penetrates through the absorbent paper when it absorbs water or is squeezed through due to defects in the middle, such as cracks.

[0209] Step 6031: If they are consistent, then the concrete abnormality information is output and the concrete penetration information is not output.

[0210] Concrete abnormality information is information about abnormal concrete production defects, such as cracks. The output method can be any method that can be recognized by the test personnel, such as text output. If they are consistent, it means that the water absorption at this time may be caused by defects such as concrete cracks, so in order to distinguish, it is necessary to send information that requires manual identification to the test personnel.

[0211] Step 6032: If they are inconsistent, output the far absorbent paper number information or the near absorbent paper number information and the concrete penetration information.

[0212] If they are inconsistent, it means that if water is absorbed here, it is not caused by cracks, but is completely due to infiltration, so it is not affected by the defects of the concrete itself, and the infiltration information can be output.

[0213] Reference Figure 8 , the method of outputting concrete abnormal information includes:

[0214] Step 700: Acquire thermal image information corresponding to the far absorbent paper number information or the near absorbent paper number information, and define it as initial thermal image information.

[0215] The initial thermal image information is the image information when the absorbent paper is absorbing. Here, the initial refers only to the image information that has not been operated. The acquisition method is the same as step 600.

[0216] Step 701: Obtain a thermoformed image of a rotated concrete specimen, and define the thermoformed image as rotational thermal image information.

[0217] The rotational thermal image information is the image information obtained after the specimen is rotated at a certain angle. Here, the rotation angle is consistent with the angle of the absorbent paper, so that after the rotation, the absorbent paper is still in the corresponding appropriate position.

[0218] Step 702: Determine whether the initial thermal image information and the rotational thermal image information are consistent.

[0219] The purpose of judgment is to determine whether the abnormal information is caused by the test piece itself or the instrument.

[0220] Step 7021: If they are consistent, output the abnormal information of the detection instrument.

[0221] If they are consistent, it means that the initial thermal image information does not move with the movement of the test piece, which means that it is fixed on the instrument, and the abnormal information of the detection instrument is output.

[0222] Step 7022: If not consistent, output concrete abnormality information.

[0223] If they are inconsistent, it means that the initial thermal image information moves with the movement of the specimen, which means it is on the specimen, and the concrete abnormality information is output.
