Abstract
Description
Technical Field
[0001] The present application relates to the field of concrete testing technology, and in particular to an alkali-aggregate reaction testing method, system, intelligent terminal and storage medium. Background Art
[0002] Alkali-aggregate reaction is a chemical reaction in concrete that typically occurs between alkaline substances in concrete (such as sodium and potassium in cement) and certain types of aggregates. This reaction can cause the concrete structure to expand, crack, and ultimately affect its durability and strength.
[0003] In the related art, the test of alkali-aggregate reaction usually takes the expansion rate of the specimen as the standard. First, the mortar needs to be loaded into a test mold equipped with an expansion probe. After the specimen is formed, it is immediately placed in a curing room with the mold. After the curing time, it is demolded and the initial length of the specimen is measured. Then, the specimen is placed in the curing room with the mold to continue curing. After different curing times, the specimens are taken out of the curing room in turn to measure the length, and the expansion probe reading is read. Finally, the expansion rate of the specimen is calculated based on the measured length, initial length and expansion probe reading.
[0004] With regard to the above-mentioned related technologies, during the test of alkali-aggregate reaction, not only is it necessary to place an expansion probe aligned with the test piece in the test mold, but the test piece also needs to be taken out of the curing room for demoulding and measurement during each measurement. After completion, the test piece is placed back into the test mold and placed in the curing room for further curing. This makes the test of alkali-aggregate reaction inconvenient and there is room for improvement. Summary of the invention
[0005] In order to improve the convenience of alkali-aggregate reaction testing, the present application provides an alkali-aggregate reaction testing method, system, intelligent terminal and storage medium.
[0006] In a first aspect, the present application provides an alkali-aggregate reaction test method, which adopts the following technical solution: A method for testing alkali-aggregate reaction, comprising: Obtaining a test trigger signal and an initial length of a preset test piece; Controlling a preset moving device to move the test piece into a preset testing room according to a test trigger signal; Control the test room to cure the specimen according to the preset specimen curing parameters, and obtain the specimen curing time of the specimen; Get the benchmark test time of the specimen; Determine whether the specimen curing time meets the requirements of the benchmark test time; If it does not meet the requirements, the test room will continue to be controlled to perform curing on the specimen according to the specimen curing parameters, and the specimen curing time of the specimen will continue to be obtained for cyclic judgment; If it meets the requirements, the preset measuring device is controlled to measure the specimen to generate the specimen age length; The specimen age length and the specimen initial length are analyzed to determine the specimen expansion ratio.
[0007] By adopting the above technical scheme, the moving device is controlled to move the test piece into the testing room, so as to control the testing room to cure the test piece. After determining that the curing time of the test piece reaches the benchmark test time, the measuring device is controlled to measure the test piece to obtain the age length of the test piece, so as to calculate the expansion rate of the test piece according to the age length of the test piece and the initial length of the test piece, without the need for personnel to control the alignment of the expansion probe and the test piece. During each measurement, the test piece is taken out of the curing room, demoulded, measured, and then placed in the curing room, thereby improving the convenience of alkali-aggregate reaction testing.
[0008] Optionally, the step of controlling a preset moving device to move the test piece into a preset testing chamber according to a test trigger signal includes: Control the moving device to move the test piece into the testing room according to the test trigger signal, and obtain the position trigger signal; Determine whether the position trigger signal meets the requirements of the preset standard position trigger signal; If it does not meet the requirements, the mobile device is controlled to move the test piece into the testing room, and the position trigger signal is obtained to perform cyclic judgment; If it meets the requirements, the moving device is controlled to stop moving the test piece, and the preset test piece clamp assembly is controlled to place the test piece into a preset curing pool.
[0009] By adopting the above technical solution, when the detection device moves the test piece, the position trigger signal is detected. When it is determined that the position trigger signal is consistent with the standard position trigger signal, it indicates that the moving device moves the test piece longitudinally to the curing and measurement position. Therefore, the movement of the test piece is stopped, and the test piece clamp assembly is controlled to place the test piece into the curing pool for curing, thereby ensuring the accuracy of the test piece position.
[0010] Optionally, the step of controlling a preset specimen clamp assembly to place the specimen into a preset curing pool includes: Obtain the first test method type of the test piece and the curing solution depth of the curing tank; Determining that the first test method type is a preset first rapid test method type or a preset first mortar length method type; If it is the first rapid test method type, the specimen clamp assembly is controlled to place the specimen into the curing tank according to the preset immersion trigger data; If it is the first mortar length method type, the curing liquid depth, the preset first erection height and the preset first specimen height are analyzed to determine the specimen insertion distance; The specimen clamp assembly is controlled according to the specimen placement distance to place the specimen above the curing liquid in the curing tank.
[0011] By adopting the above technical scheme, when the first test method type is determined to be the first mortar length method type, it indicates that the test needs to be close to the actual environment. Therefore, the specimen placement distance is determined according to the curing liquid depth, the first erection height and the first specimen height. The specimen clamp assembly is controlled according to the specimen placement distance to place the specimen above the curing liquid in the curing tank, so that the humidity of the specimen is maintained at a level close to the actual environment, thereby ensuring the maintenance of the specimen and thereby improving the accuracy of the specimen test.
[0012] Optionally, the step of controlling the specimen clamp assembly to place the specimen into the curing tank according to preset immersion trigger data includes: Determine whether the depth of the curing liquid meets the preset requirements of the benchmark specimen height; If not, the curing liquid is added to the curing tank according to the preset immersion depth to update the depth of the curing liquid, and a preset immersion trigger signal is output; If it meets the requirements, the preset immersion trigger signal is output; Analyze the depth of the curing liquid, the preset second erection height, and the preset second specimen height based on the immersion trigger signal to determine the specimen immersion distance; The specimen clamp assembly is controlled according to the immersion distance of the specimen to place the specimen into the curing liquid in the curing tank.
[0013] By adopting the above technical solution, when it is determined that the first test method type is the first rapid test method type, it indicates that rapid testing is required. Therefore, the specimen immersion distance is determined according to the curing liquid depth, the second mounting height and the second specimen height. The specimen clamp assembly is controlled according to the specimen immersion distance to place the specimen into the curing liquid, so as to promote the reaction by active means, thereby improving the efficiency of the test.
[0014] Optionally, the step of controlling a preset measuring device to measure the specimen to generate the specimen age length includes: Obtain a second test method type of the test piece; Determining that the second test method type is a preset second rapid test method type or a preset second mortar length method type; If it is the second mortar length method type, the measuring device is controlled to measure the specimen according to the preset static measurement method to generate the specimen age length; If it is the second rapid test method type, controlling the preset specimen clamp assembly to move the specimen according to the preset first measurement height; The control measuring device measures the specimen to generate the specimen age length.
[0015] By adopting the above technical solution, when the specimen is tested by the second rapid test method type, because the specimen is only kept above the curing liquid and does not touch the curing liquid, the specimen clamp assembly is directly controlled to move the specimen to the first measuring height, and the measuring device can be controlled to measure the specimen, thereby improving the convenience of measuring the specimen.
[0016] Optionally, the step of controlling the measuring device to measure the specimen according to a preset static measurement method to generate the specimen age length includes: Controlling a preset specimen clamp assembly to move the specimen according to a preset second measuring height; The specimen is placed in a static state according to preset static environment parameters, and the static time of the specimen is obtained; Determine whether the specimen standing time meets the preset benchmark standing time requirements; If it does not meet the requirements, the specimen is kept still according to the still environment parameters, and the still time of the specimen is obtained for cyclic judgment; If it meets the requirements, the measuring device is controlled to measure the specimen to generate the specimen age length.
[0017] By adopting the above technical solution, when the specimen is tested by the second mortar length method type, because the specimen is in the curing liquid with a relatively high temperature, after the specimen is taken out, it is necessary to let the specimen stand still according to the static environmental parameters before measuring, thereby reducing the influence of temperature on the specimen size and improving the accuracy of the specimen test.
[0018] Optionally, the step of controlling the measuring device to measure the specimen to generate the specimen age length includes: Controlling a preset image acquisition device to acquire images of the test piece to generate a test piece image; Perform image analysis on the specimen image to determine the specimen deflection angle; Determine whether the deflection angle of the test piece meets the requirements of the preset reference measurement angle; If it meets the requirements, the measuring device is controlled to measure the specimen to generate the specimen age length; If it does not meet the requirements, the specimen clamp assembly is controlled to adjust the specimen according to the specimen deflection angle, and an adjustment completion trigger signal is output; According to the adjustment completion trigger signal, the measuring device is controlled to measure the specimen to generate the specimen age length.
[0019] By adopting the above technical solution, the deflection angle of the specimen is determined. When it is determined that the deflection angle of the specimen exceeds the reference measurement angle, the specimen clamp assembly is controlled to adjust the specimen according to the deflection angle of the specimen, thereby ensuring that the specimen is parallel to the measurement direction along the length direction, preventing the deflection of the specimen from causing the measured length to be different from the length of the specimen, thereby improving the accuracy of the specimen measurement.
[0020] In a second aspect, the present application provides an alkali-aggregate reaction testing system, which adopts the following technical solution: An alkali-aggregate reaction testing system, comprising: An acquisition module is used to obtain a test trigger signal, an initial length of a specimen, a curing time of the specimen, and a benchmark test time; A memory for storing a program of an alkali-aggregate reaction test method as described in any one of the above items; The program in the processor memory can be loaded and executed by the processor to implement an alkali-aggregate reaction testing method as described in any one of the above items.
[0021] By adopting the above technical scheme, the processor is controlled to load and execute a program of an alkali-aggregate reaction test method stored in the memory, so that the acquisition module obtains a series of data related to the alkali-aggregate reaction test, thereby controlling the moving device to move the specimen into the detection room, and controlling the detection room to cure the specimen. After the curing is completed, the measuring device is controlled to measure the specimen to obtain the specimen age length, so as to calculate the specimen expansion rate based on the specimen age length and the specimen initial length, without the need for personnel to control the expansion probe to align with the specimen. During each measurement, the specimen is taken out of the curing room, demolded, measured, and then placed in the curing room, thereby improving the convenience of alkali-aggregate reaction testing.
[0022] In a third aspect, the present application provides a smart terminal, which adopts the following technical solution: An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and executes an alkali-aggregate reaction test method as described in any one of the above items.
[0023] By adopting the above technical scheme, by operating the intelligent terminal, the processor is made to load and execute a computer program of an alkali aggregate reaction test method stored in the memory, thereby controlling the moving device to move the test piece into the detection room, and controlling the detection room to cure the test piece. After the curing is completed, the measuring device is controlled to measure the test piece to obtain the age length of the test piece, thereby calculating the expansion rate of the test piece according to the age length of the test piece and the initial length of the test piece, without the need for personnel to control the alignment of the expansion probe with the test piece. During each measurement, the test piece is taken out from the curing room, demolded, measured, and then placed in the curing room, thereby improving the convenience of alkali aggregate reaction testing.
[0024] In a fourth aspect, the present application provides a computer storage medium capable of storing corresponding programs, which has the characteristic of facilitating the improvement of the convenience of alkali-aggregate reaction testing, and adopts the following technical solution: A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any of the above-mentioned alkali-aggregate reaction test methods.
[0025] By adopting the above technical scheme, a computer program of an alkali-aggregate reaction test method is stored in a computer-readable storage medium, so that the processor loads and executes the computer program in the storage medium, thereby controlling the moving device to move the test piece into the detection room, and controlling the detection room to cure the test piece. After the curing is completed, the measuring device is controlled to measure the test piece to obtain the age length of the test piece, so as to calculate the expansion rate of the test piece according to the age length of the test piece and the initial length of the test piece, without the need for personnel to control the alignment of the expansion probe with the test piece. During each measurement, the test piece is taken out of the curing room, demolded, measured, and then placed in the curing room, thereby improving the convenience of alkali-aggregate reaction testing.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1.

[0034] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 7 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.

[0036] Reference Figure 1 The present application discloses an alkali-aggregate reaction test method, comprising the following steps: Step S100: obtaining a test trigger signal of a preset test piece and an initial length of the test piece.
[0037] Wherein, the specimen refers to a concrete specimen for alkali-aggregate reaction test. In the embodiment of the present application, the specimen is made of 42.5 grade silicate cement and has a size of 25*25*280mm. The test trigger signal refers to the signal for starting the alkali-aggregate reaction test. The tester presses the start button to output the test trigger signal to the processing terminal. The initial length of the specimen refers to the length after the specimen is formed and cured for a certain period of time, which is obtained by the tester measuring and inputting it into the processing terminal.
[0038] Step S101: controlling a preset moving device to move the test piece into a preset testing chamber according to a test trigger signal.
[0039] After the processing terminal receives the test trigger signal, it indicates that the test piece can be tested, so the processing terminal controls the mobile device to move the test piece into the test room. The specific method is as follows Figure 2 steps to provide environmental conditions for subsequent specimen maintenance and length measurement.
[0040] The moving device refers to a device used to move the specimen, including a conveyor belt and a specimen clamp assembly. The specimen clamp assembly is installed on the conveyor belt. The specimen clamp assembly includes a turntable, a cylinder and a clamp. The clamp is used to clamp the specimen, the turntable is used to adjust the angle of the specimen, and the cylinder is used to adjust the height of the specimen. Usually, three groups of specimen clamp assemblies are set to form a control group. The test room refers to the space used for curing and measuring the length of the specimen.
[0041] Step S102: Controlling the testing room to cure the specimen according to preset specimen curing parameters, and obtaining the specimen curing time of the specimen.
[0042] Among them, after the specimen is moved into the test room, the temperature control device is controlled to maintain the specimen's curing environment at a temperature corresponding to the specimen's curing parameters, thereby curing the specimen and timing the specimen's curing time to provide data support for subsequent measurements of the specimen.
[0043] The specimen curing parameters refer to the temperature parameters for curing the specimen. If it is a rapid test, the curing temperature is about 80 degrees Celsius, and if it is a mortar length test, the curing temperature is about 40 degrees Celsius. The specimen curing time refers to the time value of the specimen curing, which is measured by the timer and sent to the processing terminal.
[0044] Step S103: Obtain the benchmark test time of the test piece.
[0045] Among them, the benchmark test time refers to the time when the specimen is measured. When the rapid method is tested, the measurement time is the 3rd, 7th and 14th day. When the mortar length method is tested, the measurement time is the 14th day, 1 month, 2 months, 3 months and 6 months. However, considering the influence of temperature, the benchmark test time of the mortar length method will be subtracted by one day on the basis of the measurement of the specimen, thereby leaving one day for temperature balance. The benchmark test time is obtained by the tester entering the processing terminal.
[0046] Step S104: Determine whether the specimen curing time meets the requirements of the benchmark test time.
[0047] The benchmark test time requirement refers to a time value corresponding to the benchmark test time, which is stored in the processing terminal by the operator. The processing terminal determines whether the specimen curing time is equal to the time value corresponding to the benchmark test time, thereby determining whether the specimen can be tested after curing.
[0048] Step S1041: If it does not meet the requirements, continue to control the test room to cure the specimen according to the specimen curing parameters, and continue to obtain the specimen curing time of the specimen for cyclic judgment.
[0049] Among them, if the processing terminal determines that the specimen curing time is not equal to the time value corresponding to the benchmark test time, it means that the specimen curing time has not reached the time for testing. Therefore, the temperature control device continues to be controlled to maintain the specimen curing environment at the temperature corresponding to the specimen curing parameters for curing, and the specimen curing time of the specimen continues to be timed, so as to continue to pay attention to the specimen curing time.
[0050] Step S1042: If it meets the requirements, control a preset measuring device to measure the specimen to generate the specimen age length.
[0051] If the processing terminal determines that the specimen curing time is equal to the time value corresponding to the benchmark test time, it means that the specimen curing time has reached the time for testing, so the measuring device is controlled to measure the specimen to obtain the specimen age length. The specific method is as follows Figure 5 steps.
[0052] The measuring device refers to a device for measuring the length of the test piece. In the embodiment of the present application, a laser rangefinder is used. In one embodiment, the laser rangefinder detects the distance between the two ends of the test piece and the wall of the test chamber respectively, and the length is obtained by subtracting the detection distance from the total distance; in another embodiment, when one end of the test piece is close to the wall of the test chamber, only the distance between one end and the wall of the test chamber is detected, and the length is obtained by subtracting the detection distance from the total distance. The specimen age length refers to the length of the specimen at different curing times, which is measured by the measuring device and sent to the processing terminal.
[0053] Step S105: Analyze the specimen age length and the specimen initial length to determine the specimen expansion rate.
[0054] The expansion rate of the specimen refers to the length change rate of the specimen. The processing terminal calculates the difference between the specimen age length and the specimen initial length to obtain the length change value, and then calculates the quotient between the length change value and the specimen initial length to obtain the expansion rate of the specimen.
[0055] Reference Figure 2 The steps of controlling a preset moving device to move the test piece into a preset detection chamber according to a test trigger signal include: Step S200: controlling the moving device to move the test piece into the testing chamber according to the test trigger signal, and obtaining a position trigger signal.
[0056] Among them, after the processing terminal receives the test trigger signal, the processing terminal responds to the test trigger signal, thereby controlling the mobile device to move the test piece toward the direction of the test room. The moving speed is determined by the tester according to the actual situation, and the position trigger signal is detected to provide data support for the subsequent determination of the position of the test piece.
[0057] The position trigger signal refers to the trigger signal of the laser sensing device at the measurement position of the test piece in the detection room. When the test piece has not reached the laser sensing device, the laser sensing device outputs a low-level signal. When the test piece reaches the laser sensing device, the sensing device outputs a high-level signal.
[0058] Step S201: determining whether the position trigger signal meets the requirements of a preset standard position trigger signal.
[0059] Among them, the standard position trigger signal refers to the trigger signal when the test piece reaches the standard position for measurement and maintenance, that is, a high-level signal. The requirement for the standard position trigger signal is that it must be consistent with the signal corresponding to the standard position trigger signal, and both are stored in the processing terminal by the operator.
[0060] The processing terminal determines whether the signal corresponding to the position trigger signal is consistent with the signal corresponding to the standard position trigger signal, thereby determining whether the moving device moves the test piece to the standard position for measurement and maintenance.
[0061] Step S2011: If not, continue to control the mobile device to move the test piece into the testing room, and continue to obtain the position trigger signal for cyclic judgment.
[0062] Among them, if the processing terminal determines that the signal corresponding to the position trigger signal is inconsistent with the signal corresponding to the standard position trigger signal, it means that the mobile device has not moved the specimen to the standard position for measurement and maintenance. Therefore, the mobile device continues to be controlled to move the specimen toward the inside of the detection room, and the laser sensing device continues to be controlled to output the position trigger signal, thereby continuously monitoring the position change of the specimen.
[0063] Step S2012: If the conditions are met, the moving device is controlled to stop moving the specimen, and the preset specimen clamp assembly is controlled to place the specimen into a preset curing pool.
[0064] If the processing terminal determines that the signal corresponding to the position trigger signal is consistent with the signal corresponding to the standard position trigger signal, it indicates that the mobile device has moved the specimen to the standard position for measurement and maintenance. Therefore, the conveyor belt in the mobile device is controlled to stop longitudinally moving the specimen, and the specimen clamp assembly is controlled to place the specimen into the maintenance pool for maintenance. For specific methods, refer to Figure 3 steps.
[0065] The specimen clamp assembly refers to a device for controlling the angle and height of the specimen, and for details, please refer to the explanation in step S101. The curing tank refers to a tank for curing time, and a sodium hydroxide solution with a concentration of 1 mol / L is contained in the curing tank.
[0066] Reference Figure 3 The steps of controlling the preset specimen clamp assembly to place the specimen into the preset curing pool include: Step S300: obtaining the first test method type of the test piece and the depth of the curing liquid in the curing tank.
[0067] Among them, the first test method type refers to the method of testing the specimen, including the rapid test method and the mortar length method. The rapid test method uses the method of actively changing the curing environment to accelerate the alkali-aggregate reaction of the specimen, thereby improving the test efficiency; the mortar length method keeps the curing environment in a normal environment, thereby improving the accuracy of the test. The first test method type is selected by the tester in the processing terminal. The depth of the curing liquid refers to the depth value of the curing liquid in the curing tank, which is detected by the liquid level sensor and sent to the processing terminal.
[0068] Step S301: determining whether the first test method type is a preset first rapid test method type or a preset first mortar length method type.
[0069] Among them, the first rapid test method type refers to a test method that actively changes the curing environment to accelerate the alkali-aggregate reaction of the specimen, and the first mortar length method type refers to a test method that maintains a normal curing environment to allow the alkali-aggregate reaction of the specimen to proceed normally, both of which are stored in the processing terminal by the testers.
[0070] The processing terminal determines that the method corresponding to the first test method type is the method corresponding to the first rapid test method type or the method corresponding to the first mortar length method type, thereby providing data support for subsequently placing the specimen in the curing pool.
[0071] Step S3011: If it is the first rapid test method type, the specimen clamp assembly is controlled to place the specimen into the curing tank according to the preset immersion trigger data.
[0072] If the processing terminal determines that the method corresponding to the first test method type is the method corresponding to the first rapid test method type, it indicates that it is necessary to actively change the curing environment to accelerate the alkali-aggregate reaction of the specimen. Therefore, the specimen clamp assembly is controlled according to the immersion trigger data to place the specimen into the curing tank. For specific methods, refer to Figure 4 steps.
[0073] The immersion trigger data refers to the data for controlling the specimen clamp assembly to immerse the specimen into the curing liquid of the curing tank, and is stored in the processing terminal by the tester.
[0074] Step S3012: If it is the first mortar length method type, the curing liquid depth, the preset first erection height and the preset first specimen height are analyzed to determine the specimen placement distance.
[0075] Among them, if the processing terminal determines that the method corresponding to the first test method type is the method corresponding to the first mortar length method type, it means that it is only necessary to maintain the curing environment as a normal environment so that the rated alkali-aggregate reaction of the specimen can proceed normally. Therefore, the specimen placement distance is determined according to the curing liquid depth, the first erection height and the first specimen height, providing data support for the subsequent placement of the specimen in the curing tank.
[0076] The first erection height refers to the height of the specimen from the curing liquid, which is determined by the tester based on the actual situation. The first specimen height refers to the height of the specimen when it is moved into the test room by the mobile device, and the specific value is determined by the tester based on the specific situation of the mobile device. The specimen placement distance refers to the moving distance of the specimen into the curing tank. The processing terminal calculates the difference between the first specimen height and the depth of the curing liquid to obtain the liquid level distance, and then calculates the difference between the liquid level distance and the first erection height to obtain the specimen placement distance.
[0077] Step S302: Control the specimen clamp assembly according to the specimen placement distance to place the specimen above the curing liquid in the curing tank.
[0078] Among them, after the processing terminal obtains the specimen placement distance, it controls the cylinder in the specimen clamp assembly to place the specimen above the curing liquid in the curing tank according to the time placement distance, thereby ensuring the humidity of the specimen curing and preventing the curing liquid from accelerating the alkali aggregate reaction of the specimen.
[0079] Reference Figure 4The steps of controlling the specimen clamp assembly to place the specimen into the curing tank according to the preset immersion trigger data include: Step S400: Determine whether the depth of the curing solution meets the preset requirement of the reference specimen height.
[0080] The reference specimen height refers to the height of the specimen itself, which is input by the tester according to the specific conditions of the specimen and stored in the processing terminal. The reference specimen height requirement is that it should not be less than the reference specimen height.
[0081] The processing terminal determines whether the depth of the curing liquid is not less than the height of the reference specimen, thereby determining whether the specimen can be completely immersed in the curing liquid for curing.
[0082] Step S401: If not, then the curing liquid is added to the curing pool according to the preset immersion depth to update the depth of the curing liquid, and a preset immersion trigger signal is output.
[0083] Among them, if the processing terminal determines that the depth of the curing liquid is less than the height of the reference specimen, it means that even if the specimen is placed in the curing liquid, part of the specimen is still exposed to the curing liquid. Therefore, liquefied liquid is added to the curing pool according to the immersion depth, thereby updating the depth of the curing liquid and outputting an immersion trigger signal to provide data support for subsequent control of the specimen immersion in the curing liquid.
[0084] The immersion depth refers to the minimum depth of the curing solution when the specimen is immersed in the curing solution. The specific value is determined by the operator according to the height of the specimen and stored in the processing terminal. The immersion trigger signal refers to the signal that controls the specimen clamp assembly to immerse the specimen in the curing solution, which is stored in the processing terminal by the tester.
[0085] Step S402: If the conditions are met, a preset immersion trigger signal is output.
[0086] If the processing terminal determines that the depth of the curing liquid is not less than the height of the reference specimen, it indicates that the specimen can be completely immersed in the curing liquid, so an immersion trigger signal is output to provide data support for the subsequent control of the specimen being immersed in the curing liquid. The immersion trigger signal in this step is consistent with the immersion trigger signal in step S401, and will not be described in detail here.
[0087] Step S403: Analyze the depth of the curing liquid, the preset second erection height, and the preset second specimen height based on the immersion trigger signal to determine the specimen immersion distance.
[0088] Among them, after the processing terminal receives the immersion trigger signal, the processing terminal calculates the specimen immersion distance according to the curing liquid depth, the second installation height and the second specimen height, providing data support for the subsequent immersion of the specimen in the curing liquid.
[0089] The second installation height refers to the distance between the specimen and the surface of the curing liquid when the specimen is immersed in the curing liquid. The specific value is determined by the tester according to the actual situation. The second specimen height in this step is consistent with the first specimen height in step S3012, and will not be repeated here. The specimen immersion distance refers to the minimum distance that the specimen needs to move to be completely immersed in the curing liquid. The difference between the second specimen height and the depth of the curing liquid is calculated by the processing terminal to obtain the liquid surface distance, and the sum of the calculated liquid surface distance and the second installation height is obtained to obtain the specimen immersion distance.
[0090] Step S404: Control the specimen clamp assembly according to the immersion distance of the specimen to place the specimen into the curing liquid in the curing tank.
[0091] Among them, after the processing terminal obtains the immersion distance of the specimen, it controls the cylinder in the specimen clamp assembly to move the specimen into the curing tank according to the time immersion distance, so that the specimen is completely immersed in the curing liquid to accelerate the alkali aggregate reaction of the specimen.
[0092] Reference Figure 5 The steps of controlling a preset measuring device to measure the specimen and generate the specimen age length include: Step S500: Obtain the second test method type of the test piece.
[0093] The second test method type in this step is consistent with the first test method type in step S300, and will not be described in detail here.
[0094] Step S501: determining whether the second test method type is a preset second rapid test method type or a preset second mortar length method type.
[0095] Among them, the second rapid test method type and the second mortar length method type in this step are consistent with the first rapid test method type and the first mortar length method type in step S301, and are not repeated here.
[0096] The processing terminal determines that the method corresponding to the second test method type is the method corresponding to the second rapid test method type or the method corresponding to the second mortar length method type, thereby providing data support for subsequent measurement of the test piece.
[0097] Step S5011: If it is the second mortar length method type, the measuring device is controlled to measure the specimen according to the preset static measurement method to generate the specimen age length.
[0098] Among them, if the processing terminal determines that the method corresponding to the second test method type is the method corresponding to the second mortar length method type, it indicates that the specimen is cured in a curing environment close to the actual environment, and the test tends to be accurate. Therefore, it cannot be measured directly, but needs to be left to stand before measurement. Therefore, the measuring device is controlled according to the static measurement method to measure the specimen to generate the specimen age length. For specific methods, refer to Figure 6 steps.
[0099] The static measurement method refers to the method of measuring after the specimen is left static. For specific methods, refer to Figure 6 steps.
[0100] Step S5012: If it is the second rapid test method type, the preset test piece clamp assembly is controlled to move the test piece according to the preset first measurement height.
[0101] Among them, if the processing terminal determines that the method corresponding to the second test method type is the method corresponding to the second rapid test method type, it indicates that the specimen is cured in an environment immersed in the curing liquid, and the test tends to be efficient. Therefore, the specimen can be measured directly, thereby controlling the cylinder of the specimen clamp assembly according to the first measurement height to raise the specimen to the same level as the measuring device, providing basic support for subsequent measurements.
[0102] The first measurement height refers to the height at which the test piece is measured, and is determined by the tester according to the height of the measuring device. The test piece clamp assembly in this step is consistent with the test piece clamp assembly in step S2012, and will not be described in detail here.
[0103] Step S502: Control the measuring device to measure the specimen to generate the specimen age length.
[0104] When the specimen is moved to the first measuring height, the measuring device is controlled to measure the specimen, thereby obtaining the specimen age length. The specific method is as follows: Figure 7 steps.
[0105] Reference Figure 6 The steps of controlling the measuring device to measure the specimen according to the preset static measurement method to generate the specimen age length include: Step S600: controlling a preset specimen clamp assembly to move the specimen according to a preset second measurement height.
[0106] Among them, after determining that it is necessary to stand still before measuring, the processing terminal controls the cylinder in the specimen clamp assembly to raise the specimen to a second measuring height, so that the specimen and the measuring device are on the same horizontal plane, providing basic support for subsequent measurements.
[0107] The second measurement height in this step is consistent with the first measurement height in step S5012, and will not be described in detail here. The specimen clamp assembly in this step is consistent with the specimen clamp assembly in step S2012, and will not be described in detail here.
[0108] Step S601: placing the specimen at rest according to preset resting environment parameters, and obtaining the resting time of the specimen.
[0109] Among them, after the specimen is moved to the second measuring height, the temperature control device changes the ambient temperature according to the temperature control corresponding to the static environmental parameters and then the specimen is left to stand, so as to balance the internal and external temperatures of the specimen to prevent the temperature from affecting the length measurement of the specimen, and the static time of the specimen is collected to provide data support for the subsequent determination of whether measurement is possible.
[0110] The static environment parameter refers to the temperature at which the specimen is static, which is usually set to 20 degrees Celsius. The specimen static time refers to the time for which the specimen is static, which is counted by a timer and sent to the processing terminal.
[0111] Step S602: Determine whether the specimen standing time meets the preset reference standing time requirement.
[0112] The reference standing time refers to the time the specimen needs to stand, which is usually 24 hours. The reference standing time requirement refers to a time not less than the reference standing time.
[0113] The processing terminal determines whether the corresponding time of the specimen standing time is not less than the reference standing time, thereby determining whether the specimen standing time is long enough.
[0114] Step S6021: If not, continue to place the specimen at rest according to the resting environment parameters, and continue to obtain the specimen resting time for cyclic judgment.
[0115] Among them, if the processing terminal determines that the time corresponding to the specimen standing time is less than the benchmark standing time, it means that the specimen has been standing for a short time. At this time, the temperature may also affect the length measurement of the specimen. Therefore, the temperature control device continues to be controlled to stand the specimen at a temperature corresponding to the standing environment parameters, so as to continue to balance the temperature of the specimen, and continue to time the specimen standing time, so as to continue to pay attention to the standing condition of the specimen.
[0116] Step S6022: If it meets the requirements, the measuring device is controlled to measure the specimen to generate the specimen age length.
[0117] If the processing terminal determines that the corresponding time of the specimen static time is not less than the reference static time, it means that the specimen static time is sufficient, and the temperature will not affect the length measurement of the specimen. Therefore, the measuring device is controlled to measure the specimen and generate the specimen age length. The specific method is referred to Figure 7 steps.
[0118] Reference Figure 7 The steps of controlling the measuring device to measure the specimen and generate the specimen age length include: Step S700: controlling a preset image acquisition device to acquire an image of the specimen to generate a specimen image.
[0119] Before the measuring device measures the test piece, the image acquisition device is controlled to take a picture of the test piece, thereby obtaining an image of the test piece to provide data support for subsequent measurements.
[0120] The image acquisition device refers to an industrial camera installed in the test room for taking pictures of the test piece. The test piece image refers to the image taken of the test piece, which is taken by the image acquisition device and sent to the processing terminal.
[0121] Step S701: performing image analysis on the specimen image to determine the specimen deflection angle.
[0122] The specimen deflection angle refers to the angle between the length direction of the specimen and the measurement direction, which is obtained by the processing terminal identifying the contour of the specimen in the specimen image and then identifying and determining the angle between the contour line and the measurement line.
[0123] Step S702: Determine whether the deflection angle of the test piece meets the requirement of the preset reference measurement angle.
[0124] The reference measurement angle refers to the maximum angle that can be measured. The specific value is determined by the tester based on the actual situation. The requirement for the reference measurement angle is that it should not be greater than the reference measurement angle.
[0125] The processing terminal determines whether the deflection angle of the test piece is not greater than the reference measurement angle, thereby determining whether the current direction of the test piece can be directly measured.
[0126] Step S7021: If it meets the requirements, the measuring device is controlled to measure the specimen to generate the specimen age length.
[0127] Among them, if the processing terminal determines that the deflection angle of the specimen is not greater than the reference measurement angle, it means that the length direction of the specimen is almost parallel to the measurement direction. At this time, the measurement error is extremely small. Therefore, the measuring device is controlled to directly measure the length of the specimen to obtain the age length of the specimen.
[0128] Step S7022: If not, the specimen clamp assembly is controlled to adjust the specimen according to the specimen deflection angle, and an adjustment completion trigger signal is output.
[0129] Among them, if the processing terminal determines that the deflection angle of the specimen is greater than the reference measurement angle, it means that the angle between the length direction of the specimen and the measurement direction is large. At this time, the measurement error is large. Therefore, the turntable in the specimen clamp assembly is controlled to adjust the direction of the specimen according to the deflection angle of the specimen, so that the length direction of the specimen is parallel to the measurement direction, and an adjustment completion trigger signal is output to provide data support for subsequent measurements.
[0130] The adjustment completion trigger signal refers to the signal indicating that the adjustment of the length direction of the test piece is completed, and is stored in the processing terminal by the tester.
[0131] Step S703: controlling the measuring device to measure the specimen according to the adjustment completion trigger signal to generate the specimen age length.
[0132] Among them, after the processing terminal receives the adjustment completion trigger signal, the length direction of the specimen is almost parallel to the measurement direction, and the measurement error is extremely small. Therefore, after the processing terminal controls the measuring device to measure the length of the specimen, the age length of the specimen can be obtained.
