Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-9 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

Referring to fig. 1, an embodiment of the present invention provides a method for detecting concrete impermeability, and the main flow of the method for detecting concrete impermeability is described as follows:

step 100: after the test piece is placed and is completed, the detection instrument moves downwards to be close to the test piece, absorbent paper is clamped on the detection instrument and is uniformly distributed in a fan shape, all the absorbent paper forms a disc, and the clamping position is arranged along the circumferential direction of the absorbent paper.

The detection device is as shown in fig. 2, the absorbent paper is arranged along the circumferential direction, all the absorbent paper is clamped by two weighing devices with weight measuring functions, the weighing devices are distributed along the circle a and the circle b respectively, the absorbent paper can rotate around the inner ring, the clamping columns on the outer ring penetrate through the long waist holes and then abut against the lower side of the absorbent paper, and the absorbent paper and the clamping columns can extend under the action of weight and are similar to a tension meter. It should be noted that the density of the absorbent paper decreases from the outside to the inside, so that the absorbent paper can be kept horizontal while it is on the two weighing devices in a dry state. In order to ensure the absorption rate, a component such as calcium carbonate may be coated on the absorbent paper.

Step 101: acquiring the in-place information of the absorbent paper positioned above the test piece and the infrared induction information positioned between the test piece and the absorbent paper.

The absorbent paper in-place information refers to information that the absorbent paper reaches a corresponding position capable of adsorbing water stains on the upper surface of the test piece, and the position has a certain distance from the surface of the test piece, but water drops and the like higher than the upper surface of the test piece can also be adsorbed. The acquisition mode can be an infrared sensor, and when the water absorption paper exists above the water absorption paper, the signal receiver at the other end can not receive the infrared signal and then outputs the in-place information of the water absorption paper to the terminal.

The infrared sensing information refers to information of received infrared rays in a gap between the absorbent paper and the upper surface of the test piece when the absorbent paper reaches a position corresponding to the in-place information of the absorbent paper. As can be seen from fig. 2, the ir sensing information can also be generated by an ir emitter, and the other end of the ir sensing information has a corresponding receiving device, the ir emitter is disposed outside the half-circle, and the receiver is disposed in the opposite zone.

Step 102: and judging whether the in-place information and the infrared sensing information of the absorbent paper exist.

The purpose of the judgment is to determine whether the absorbent paper is in place and whether the absorbent paper moves downwards due to water absorption.

Step 1021: and if the in-place information and the infrared sensing information of the absorbent paper exist, stopping moving downwards, acquiring the weight of the absorbent paper at the current time, and defining the weight as dry weight information.

The dry weight information is weight information of the water absorbent paper in a dry state. Since the absorbent paper is in an anhydrous state at the beginning stage, when the absorbent paper is triggered to be in place, the absorbent paper is in place, and since the infrared sensing information also exists, the absorbent paper does not fall, namely the absorbent paper does not absorb water, and the information is the dry weight information.

Step 1022: if the in-place information of the absorbent paper does not exist but the infrared sensing information exists, the absorbent paper is continuously moved downwards.

There are two situations in the water absorption paper in-place information: the water absorption paper absorbs water and sinks or the water absorption paper does not sink yet, and the infrared sensing information shows that the water absorption paper does not sink yet, and at the moment, the water absorption paper does not reach the position corresponding to the water absorption paper in-place information, and the water absorption paper needs to be moved downwards to a specified position to perform a water absorption test.

Step 1023: and if the in-place information of the absorbent paper exists but the infrared sensing information does not exist, acquiring the weight on the absorbent paper, and defining the weight as the absorbent gravity information.

The water absorption gravity information is the weight of water absorption on the water absorption paper. Here, an integral weighing device is provided above the entire device, by means of which the entire mass after water absorption is determined.

Step 103: and judging whether the water absorption gravity information is larger than the dry weight information.

The purpose of the judgment is to determine whether or not water is absorbed.

Step 1031: and if the weight is larger than the dry weight information, outputting infiltration information.

The penetration information is any information that can be viewed and identified by the test person, such as a red light. If the moisture content is larger than the dry weight information, the moisture absorption paper absorbs moisture at the moment, and the test piece shows that the water seepage starts under the current water pressure.

Step 1032: if the weight information is equal to the dry weight information, the falling information of the absorbent paper is output and the tester is warned.

The absorbent paper falling information is information that the absorbent paper falls from the weighing device, and here may be any indication information, such as a yellow light. Since the absorbent paper has fallen but has not absorbed water, a possible cause may be an external disturbance or the like, and the absorbent paper falling information is output to indicate to the test person that the test person needs to check it.

Step 104: and judging whether the equipment for outputting the penetration information is more than the preset specified amount of information.

The specified amount information is information specifying the number of devices for which the infiltration information needs to be present. In the present embodiment, if the number of all the test pieces is 6, the prescribed number information is set to 3 in advance. The purpose of the judgment is to determine whether the detection is finished. The specific numerical value is defined by the content in the specification, and is not described herein again.

Step 1041: and if the quantity of the water pressure is equal to the specified quantity of the information, stopping working, and acquiring and outputting the current water pressure level information.

The current water pressure grade information is the information of the water pressure grade displayed on the water pressure display meter of the current water valve, and is actually the content displayed on the dial plate in the pressurizing process each time. The acquisition mode can be image reading, and can also be obtained by internal water pressure detection, such as a water pressure meter and the like. If the quantity is equal to the specified quantity of information, the test is finished at the moment, the performance detection is finished, the work is stopped at the moment, then the corresponding water pressure grade is output, and the conversion formula for outputting the impermeability grade is a conventional calculation formula in the field, which is not described herein any more.

Step 1042: if the number of the pieces of information is less than the prescribed number, the test is continued.

If the quantity is less than the specified quantity information, the impermeability grade meeting the specification requirement is not achieved, and the test is continued to obtain the corresponding water pressure.

Referring to fig. 3, the penetration information includes sealing ring penetration information and concrete penetration information, and the method of distinguishing the sealing ring penetration information from the concrete penetration information includes:

step 200: and acquiring outer ring weight information and inner ring weight information of the weighing device arranged along the circumferential direction of the test piece.

The outer ring weight information is the information of the weight detected on the same weighing device on the ring b in fig. 2. The inner ring weight information is information of the detected weight on the weighing device on ring a in fig. 1. The sum of the outer ring weight information and the inner ring weight information is the total weight information of the absorbent paper. The acquisition mode and the principle of the tension meter, namely how long the stretch is, the multiple.

Step 201: and calculating difference information according to the water absorption gravity information and the dry weight information, and defining the difference information as water absorption weight information.

The difference information is information on the water absorption gravity, and the difference between the water absorption gravity information and the dry weight information is calculated. The purpose of the acquisition is to determine how much moisture is absorbed.

Step 202: and respectively carrying out matching analysis with the outer ring weight information and the inner ring weight information according to the lengths stored in the preset length database to determine the lengths corresponding to the outer ring weight information and the inner ring weight information, defining the length corresponding to the outer ring weight information as the outer ring length information, and defining the length corresponding to the inner ring weight information as the inner ring length information.

The outer ring length information is information of the length of the outer ring of the weighing device. The database stores the mapping relation between the length information and the weight information, namely when the weight information is input, the mapping relation comprises the outer ring weight information and the inner ring weight information, and the system automatically searches the corresponding weight information from the database and outputs the information. The database is the result of a limited number of trials by workers in the field.

Step 203: and calculating the current inclination amplitude information according to the outer ring length information and the inner ring length information.

The current inclination amplitude information is information of the inclination of the absorbent paper under the current actual condition. The calculation is tan phi = (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, i.e., the diameter difference between the outer circle and the inner circle. When the value is calculated, phi is reversely output, namely the current inclination amplitude information is obtained.

Step 204: and performing matching analysis according to the inclination amplitude stored in the preset inclination database and the water absorption weight information to determine the inclination amplitude corresponding to the water absorption weight information, and defining the inclination amplitude as approved inclination amplitude information.

The information of the amplitude of inclination is approved as information of the amplitude of inclination when the water absorbing position is on the outer race and the water content of the information of the water absorbing weight corresponds to moisture. The inclination database stores the mapping relation between the corresponding water absorption weight information and the inclination amplitude, and is obtained by the staff in the field through tests. When the corresponding water absorption weight information is calculated, the system automatically retrieves the corresponding inclination amplitude information from the inclination database.

Step 205: and judging whether the current inclination amplitude information is larger than the approved inclination amplitude information.

The purpose of the judgment is to determine the position of water absorption. The location of the water absorption can basically also be determined because of the nature of the absorbent paper, the process of absorption must start from the point of absorption and spread out and the point of absorption is the greatest in weight.

Step 2051: if the inclination amplitude information is larger than the approved inclination amplitude information, outputting the penetration information of the sealing ring and outputting warning information.

The penetration information of the sealing ring is information that a gap exists between the time and the device so that water penetrates upwards from the time and the device. The warning information is information that can be recognized by the test person, such as a red light, and indicates insufficient sealability below the corresponding light. If the inclination amplitude information is larger than the approved inclination amplitude information, the inclination degree is larger, the lever principle can know that the farther the object is away from the rotation center, the larger the generated action effect is, the water absorption point is positioned outside the outer ring at the moment, the position of the sealing ring is shown outside the outer ring, the sealing performance is poor at the moment, and the water permeates from the gap between the test piece and the device, so that the sealing ring permeation information and the warning information are output.

Step 2052: and if the inclination amplitude information is smaller than the approved inclination amplitude information, outputting concrete penetration information and outputting normal working information.

The normal operation information is information that the test piece normally operates, and may be any kind of identifiable information, such as a green light. If the inclination amplitude information is less than the approved inclination amplitude information, the water absorption position is in the outer ring, and the inner part of the outer ring is on the test piece, so that the sealing performance is good and the water normally permeates.

Referring to fig. 4, the method for locating the position of the concrete penetration information includes:

step 300: acquiring single infrared sensing information and sensor number information which are arranged along the semi-circumference of the test piece, defining the sum of all the single infrared sensing information as infrared sensing information, and defining that the infrared sensing information does not exist when one infrared sensor does not receive sensing.

The single infrared sensing information is the single infrared sensing information, which has already been described in fig. 2 and step 101, and is not described herein again.

Step 301: and screening the sensor number information without the single infrared sensing information, and defining the sensor number information as abnormal sensor number information.

The abnormal sensor number information is the number information of the sensor without the single infrared sensing information. Namely, when the infrared induction information is not received by the opposite receiver, the number information is output to the intelligent terminal.

Step 302: and performing matching analysis according to the water absorption paper number and the abnormal sensor number information stored in the preset water absorption paper number database to determine the water absorption paper number corresponding to the abnormal sensor number information, wherein the number of the water absorption paper corresponding to one sensor is two, one piece far away from the sensor is defined as the number information of the far water absorption paper, and the other piece close to the sensor is defined as the number information of the near water absorption paper.

The number information of the far absorbent paper is the number information of the absorbent paper which is far away and corresponds to the number information of the abnormal sensor. The number information of the near absorbent paper is the number information of the absorbent paper which is close to the number information of the abnormal sensor correspondingly. Since only half of the infrared sensor is provided, the infrared sensor may not receive information, and may be any of the symmetrical absorbent papers. The database stores the mapping relation between the absorbent paper number information and the abnormal sensor number information, and the mapping relation is observed and input by workers in the field according to specific conditions.

Step 303: and obtaining feedback distance information sent by the number information of the abnormal sensor.

The feedback distance information is the information of the distance reflected after the infrared emitter corresponding to the abnormal sensor number information sends infrared rays. In the device, a receiver is arranged opposite to the infrared transmitter, a receiver is also arranged at the same end, and if the receiver at the same end receives the information, the feedback distance information is output, and the specific acquisition mode is any distance measurement mode, such as an infrared distance meter.

Step 304: and comparing the feedback distance information with the distance corresponding to the preset intermediate distance information.

The intermediate distance information is the distance from the infrared distance meter to the center of the detection device, and is obtained by measurement of workers in the field before the test. The purpose of the comparison is to determine whether the location of the range is on the side of the center closer to the transmitter or the side further away.

Step 3041: and if the feedback distance information is greater than the distance corresponding to the middle distance information, outputting the number information of the far absorbent paper and the concrete penetration information.

If the feedback distance information is larger than the distance corresponding to the middle distance information, the fact that the water absorption paper disturbing the infrared ray is on the side far away from the center is indicated, and the number information of the far water absorption paper and the concrete penetration information can be output.

Step 3042: and if the feedback distance information is smaller than the distance corresponding to the intermediate distance information, outputting the number information of the near absorbent paper and the concrete penetration information.

If the feedback distance information is smaller than the distance corresponding to the middle distance information, the fact that the absorbent paper disturbing the infrared ray is on the side close to the center at the moment is indicated, and the information can be output as the number information of the near absorbent paper and the concrete penetration information.

Referring to fig. 5, the method for determining the in-place information of the absorbent paper comprises the following steps:

step 400: and acquiring distance information when each weighing device moves downwards to the water absorption paper in place information and the infrared sensing information exist, then continuously moving downwards and acquiring the detection numerical value of the bearing device in real time, and defining the detection numerical value as the detection weight information.

The distance information is the distance that the weighing device moves downwards when the weighing device moves downwards to the position corresponding to the water absorption paper in-place information, and the purpose here is to determine a reference value for checking. The detected weight information is the information of the weight measured on the weighing device, when the weighing device and the absorbent paper touch the test piece, the weight detected by the weighing device is correspondingly reduced, and the obtained weight information is compared with the dry weight information. It should be noted that the method herein is a method prior to the test, i.e., after the test piece is placed on the instrument and before the impermeability test.

Step 401: it is determined whether the detected weight information is equal to the dry weight information.

The purpose of the judgment is to determine whether the weighing device is abutted to the test piece in the downward moving process.

Step 4011: if the detected weight information is equal to the dry weight information, the downward movement is continued.

If the detected weight information is equal to the dry weight information, it indicates that the detected weight is not changed, and it indicates that the detected weight has not been reached yet.

Step 4012: and if the detected weight information is less than the dry weight information, acquiring the downward moving distance of the weighing device at the moment, and defining the downward moving distance as the detected distance information.

The detection distance information is information of the distance of downward movement of the weighing device obtained when the detection weight information is smaller than the dry weight information, and the acquisition mode can be acquired by the instrument. If the detected weight information is smaller than the dry weight information, indicating that the test piece has been pushed against the test piece, the detected distance information at this time may be output in order to determine the distance from the distance information to the start of the downward shift.

Step 402: and judging whether all the detection distance information is consistent.

The purpose of the judgement is to determine that the surface of all test pieces tested is a horizontal plane, and it should be noted that the lowermost ends of all weighing devices in the process of being lowered together are on a horizontal plane. The purpose of the judgment is to determine whether the object is on a horizontal plane.

Step 4021: and if the detected distance information is consistent, moving the weighing device to the position corresponding to the distance information and detecting.

If the detected distance information is consistent, the fact that the distances of all weighing devices moving downwards are the same and the distances of all weighing devices abutting against the time surface are the same indicates that the processing method of the test piece is correct and the test piece can be normally used, and the test piece can be moved to the position corresponding to the water absorption paper in-place information to start a test.

Step 4022: and if the detected distance information is inconsistent, outputting the information of the unevenness of the concrete surface and warning.

The concrete surface unevenness information indicates information on the surface of the test piece. If the detected distance information is inconsistent, the fact that the distance of the weighing device moving downwards is inconsistent is indicated, the fact that the surface of the test piece is not smooth is indirectly indicated, and the information of the unevenness of the concrete surface is output and is warned.

Referring to fig. 6, a method of detecting a state of absorbent paper is also included, the method including:

step 500: and calculating difference distance information according to the intermediate distance information and the feedback distance information.

The difference distance information is the difference information between the middle distance information and the feedback distance information, namely the distance between the center and the infrared emitter, and the light rays emitted by the infrared emitter are on the absorbent paper.

Step 501: and calculating actual height information according to the inner ring length information, the current inclination amplitude information and the difference distance information.

The actual height information is the height information of the light rays emitted by the infrared emitter on the absorbent paper. The calculation mode is the conversion of proportion, and the calculation formula is as follows: h = L2+ tan Φ Δ L, where Δ L is difference distance information.

Step 502: and comparing the actual height information with the preset horizontal infrared height information.

The horizontal infrared ray height information is information of the height of infrared rays emitted by an infrared emitter which is arranged on the detection device in advance and used for detecting the position of a gap between the absorbent paper and the test piece. The purpose of the comparison is to determine whether the absorbent paper is inclined in a straight line and thus to determine whether the absorbent paper still maintains the original shape.

Step 5021: if the actual height information is inconsistent with the horizontal infrared height information, outputting water absorption paper softening information and warning.

The absorbent paper softening information is information that the absorbent paper is softened after absorbing water and cannot maintain the original shape. If the actual height information and the horizontal infrared ray height information are not consistent, the fact that the absorbent paper creek is deformed after water absorption is described, the absorbent paper with a better absorption effect needs to be replaced because the shape of the absorbent paper cannot be maintained, and the warning condition can be in any form, such as character display.

Step 5022: and if the actual height information is consistent with the horizontal infrared height information, normally outputting concrete penetration information.

If the actual height information is not consistent with the horizontal infrared height information, the water absorption paper still maintains the original shape at the moment, the steps of the previous method still meet the requirements of the method at the moment, and the water absorption paper is normally operated and output without being corrected or replaced.

Referring to fig. 7: also included is a method of concrete inspection, the method comprising:

step 600: and acquiring thermal image information corresponding to the detection area corresponding to the serial number of the absorbent paper.

The thermal image information is information of the receiving thermoformed image above the weighing device. The water can be replaced by hot water below the test piece, so that imaging can be easier, and the acquisition mode is a camera capable of receiving thermal image information, such as an infrared thermal imager.

Step 601: and judging whether all the thermal image information is consistent.

The purpose of the judgment is to determine whether the concrete conditions are consistent in all positions so as to judge whether the concrete is uniformly arranged.

Step 6011: if the two are consistent, the detection is continued.

If the two areas are consistent, the situation that each area is the same is explained, most of the areas are similar, and the areas are in a dense state, and the detection can be continued.

Step 6012: and if the thermal image information is inconsistent with the approved thermal image information, distinguishing the thermal image information with a large number of consistency, defining the thermal image information as approved thermal image information, and defining the thermal image information inconsistent with the approved thermal image information as abnormal thermal image information.

The approved thermal image information is thermal image information with a large number of consistency, and the thermal image information inconsistent with the thermal image information is defined as abnormal thermal image information. In the screening mode, the standard is used as the standard when the test piece is manufactured manually, so that the standard thermal image information is more in actual conditions, and the standard thermal image information is defined as approved thermal image information.

Step 602: and acquiring the number of the absorbent paper corresponding to the abnormal thermal image information, and defining the number as the number information of the problem absorbent paper.

And the serial number information of the defective absorbent paper is the absorbent paper corresponding to the detection area with abnormal thermal image information. The acquired mode can be that the serial number database is searched, namely, the serial number information of the absorbent paper corresponding to the area corresponding to the abnormal thermal image information is stored in the database.

Step 603: and judging whether the number corresponding to the number information of the far absorbent paper or the number information of the near absorbent paper is consistent with the number information of the problem absorbent paper.

The purpose of the judgment is to determine whether the water is penetrated when the absorbent paper absorbs water or the water is squeezed due to the existence of defects such as cracks in the middle.

Step 6031: and if the information is consistent with the preset information, outputting concrete abnormal information and not outputting concrete penetration information.

The concrete abnormality information is information that concrete production abnormality is defective, such as cracks. The output mode can be any mode which can be recognized by the tester, such as a text output. If the difference is equal, the fact that water is absorbed at this time is probably caused by defects such as concrete cracks, so that information which needs to be manually distinguished needs to be sent to a tester for distinguishing.

Step 6032: and if the difference is not consistent, outputting the number information of the far absorbent paper or the number information of the near absorbent paper and the concrete penetration information.

If the difference is not consistent, the result shows that if the water is absorbed, the water is not caused by cracks, and the water is completely in a penetration mode, so that the penetration information can be output without being influenced by the defects of the concrete.

Referring to fig. 8, the method of outputting concrete abnormality information includes:

step 700: and acquiring thermal image information corresponding to the number information of the far absorbent paper or the number information of the near absorbent paper, and defining the thermal image information as initial thermal image information.

The initial thermal image information is image information when the absorbent paper absorbs the image information, and the initial thermal image information only refers to information of an image which is not operated, and the obtaining mode is consistent with the step 600.

Step 701: and acquiring a hot forming image of the concrete sample after rotation, and defining the hot forming image as the rotating thermal image information.

The rotating thermal image information is image information obtained after the test piece rotates according to a certain angle. The angle of rotation is consistent with the angle of the absorbent paper, so that the absorbent paper is still in the corresponding proper position after rotation.

Step 702: and judging whether the initial thermal image information is consistent with the rotary thermal image information.

The purpose of the judgment is to determine whether the cause of the generation of abnormal information is the cause of the specimen itself or the cause of the instrument.

Step 7021: and if the detection result is consistent with the preset detection result, outputting abnormal information of the detection instrument.

If the initial thermal image information is consistent with the movement of the test piece, the initial thermal image information does not move along with the movement of the test piece, if the initial thermal image information is fixed on the instrument, abnormal information of the detection instrument is output.

Step 7022: and if the concrete abnormal information is inconsistent with the preset information, outputting the concrete abnormal information.

If the initial thermal image information is inconsistent with the movement of the test piece, the initial thermal image information is moved along with the movement of the test piece, and if the initial thermal image information is on the test piece, the concrete abnormal information is output.
