Description

Technical Field

[0001] The present application relates to the field of concrete detection technology, and in particular to a concrete crack resistance detection method, system, intelligent terminal and storage medium. Background Art

[0002] Concrete cracking is a problem that has always existed in the application of cement concrete system. It is determined by the inherent material properties of concrete. That is, in the process from pouring to solidification of concrete, various shrinkages are subject to various constraints and internal tensile stress is generated. When this tensile stress is greater than the tensile strength, cracks will occur.

[0003] In related technologies, early concrete crack resistance detection is generally carried out by inducing cracks in concrete specimens. Workers use a combination of direct observation and instrument observation to collect the crack area ratio of the concrete specimens, and then evaluate based on the crack area ratio to determine the results of the concrete crack resistance test.

[0004] Regarding the above-mentioned related technologies, the crack resistance of concrete is evaluated by observing cracks. Although the effect is intuitive, most of the early crack resistance is insensitive. In the early stages of concrete strength development, such as 1 to 3 days, it is often manifested as high stress and high toughness, and is rarely directly manifested as actual cracking. Direct observation of cracks can easily fail to accurately detect changes in concrete crack resistance in the early stages, resulting in inaccurate concrete crack resistance detection. There is still room for improvement. Summary of the invention

[0005] In order to improve the accuracy of concrete crack resistance detection, the present application provides a concrete crack resistance detection method, system, intelligent terminal and storage medium.

[0006] In the first aspect, the present application provides a concrete crack resistance detection method, which adopts the following technical solution: A concrete crack resistance detection method, comprising: Obtaining the concrete specimen preparation completion trigger information; According to the preparation completion trigger information, a preset strain force detection device is controlled to detect the strain force of the concrete specimen to determine the preliminary strain data information; Obtain the detection time information of the concrete specimen; Determine whether the detection time information meets the requirements of the preset induction time information; If it does not meet the requirements, the detection time information of the concrete specimen will continue to be obtained for cyclic judgment; If it meets the requirements, the preset induction device is controlled to induce the concrete specimen to crack, and the strain force detection device is controlled to detect the strain force of the concrete specimen to determine the later strain data information; Draw the strain statistics chart of the concrete specimen based on the early strain data and the later strain data.

[0007] By adopting the above technical scheme, after detecting the trigger information of preparation completion, the strain force detection device is controlled to detect the strain force of the concrete specimen to determine the early strain data information, so that when the cracks of the concrete specimen are not obvious in the initial stage of production, the strain force directly reflects the nature of concrete cracking, and when the detection time information is consistent with the induction time information, the induction device is controlled to induce the concrete specimen to crack, and the strain force detection device is synchronously controlled to detect the strain force of the concrete specimen to obtain the later strain data information, so as to induce cracking and strain force detection of the concrete specimen that can be actively induced, thereby improving the accuracy of concrete crack resistance detection.

[0008] Optionally, the step of controlling a preset strain force detection device to detect the strain force of the concrete specimen according to the preparation completion trigger information to determine the preliminary strain data information includes: According to the preparation completion trigger information, the strain force detection device is started to detect the concrete specimen to determine the early strain data information and obtain the temperature detection information of the concrete specimen; Acquire the influence temperature information of the strain force detection device; Determine whether the temperature detection information meets the requirements affecting the temperature information; If it does not meet the requirements, the strain force detection device is continuously controlled to detect the concrete specimen to determine the early strain data information, and the temperature detection information of the concrete specimen is continuously obtained to perform cyclic judgment; If it meets the requirements, the strain force detection device is controlled to detect the concrete specimen according to the preset temperature compensation method to determine the early strain data information.

[0009] By adopting the above technical scheme, when it is determined that the temperature detection information of the concrete specimen meets the requirements of the influencing temperature information, that is, the temperature detection information is not lower than the influencing temperature information, it indicates that the temperature of the concrete specimen will affect the accuracy of the strain force detection device. Therefore, the strain force detection device is controlled according to the temperature compensation method to detect the concrete specimen to determine the preliminary strain data information, thereby improving the accuracy of concrete crack resistance detection.

[0010] Optionally, the step of controlling the strain force detection device to detect the concrete specimen according to a preset temperature compensation method to determine the preliminary strain data information includes: Controlling a preset temperature compensation device to perform temperature compensation on the strain force detection device, and controlling the strain force detection device to detect the concrete specimen to determine basic strain data information; Acquiring device temperature information of the strain force detection device; Determine whether the device temperature information meets the requirements affecting the temperature information; If it does not meet the requirements, the basic strain data information is defined as the preliminary strain data information, and the temperature compensation device is continuously controlled to perform temperature compensation on the strain force detection device; If it is in compliance, correction is performed according to the basic strain data information to determine the previous strain data information, and the temperature compensation device is continuously controlled to perform temperature compensation on the strain force detection device.

[0011] By adopting the above technical solution, the temperature compensation device is controlled to perform temperature compensation on the strain force detection device, thereby reducing the influence of temperature on the strain force detection device, and the temperature information of the device is detected. When the temperature information of the device meets the requirements of the influencing temperature information, that is, when it is not lower than the influencing temperature information, the basic strain data information is corrected to determine the preliminary strain data information, and temperature compensation is continued to reduce the influence of temperature, thereby improving the accuracy of concrete crack resistance detection.

[0012] Optionally, the step of controlling a preset temperature compensation device to perform temperature compensation on the strain force detection device includes: Obtain temperature abnormality sequence number information of temperature detection information; Determine temperature compensation position information according to temperature anomaly sequence number information and preset sequence number position relationship information; The temperature compensation device is controlled according to the temperature compensation position information to perform temperature compensation on the strain force detection device.

[0014] Optionally, the step of controlling the temperature compensation device to perform temperature compensation on the strain force detection device according to the temperature compensation position information includes: Start the corresponding temperature compensation device according to the temperature compensation position information, and analyze the device temperature information and the influencing temperature information to determine the temperature deviation information; Determine system parameter information according to temperature detection information and preset temperature parameter relationship information; Analyze the system parameter information and the temperature deviation information to determine the temperature control power information; The temperature compensation device activated according to the temperature control power information controls the temperature compensation of the strain force detection device.

[0015] By adopting the above technical scheme, the temperature deviation information that needs to be reduced in the strain force detection device is determined, and then the system parameter information is determined based on the temperature detection information and the temperature parameter relationship information, so that the system determines the temperature control power information based on the system parameter information and the temperature deviation information, and then controls the temperature compensation device according to the temperature control power information to perform temperature compensation on the strain force detection device, thereby improving the accuracy of temperature compensation.

[0017] By adopting the above technical solution, the basic strain data information is converted into the output voltage information of the strain force detection device, and then the correction temperature information is determined, so that the correction voltage information is determined according to the output voltage information, the correction temperature information and the temperature coefficient information, thereby eliminating the influence of temperature on the output voltage, and then the correction voltage information is converted into the preliminary strain data information, thereby improving the accuracy of the preliminary strain data information.

[0018] Optionally, the step of obtaining temperature detection information of a concrete specimen includes: Obtain the standing time information of concrete specimens; Determine whether the static time information meets the requirements of the preset impact time information; If it meets the requirements, the preset temperature detection device is controlled to stop detecting the temperature detection information of the concrete specimen; If it does not meet the requirements, the preset temperature detection device is controlled according to the preset detection frequency information to detect the concrete specimen to determine the temperature detection information.

[0019] By adopting the above technical scheme, when the static time information meets the requirements of the influencing time information, that is, when the static time information exceeds the influencing time information, it indicates that the temperature of the concrete specimen will not change significantly, so the temperature detection is stopped; when it does not exceed the influencing time information, it indicates that the temperature of the concrete specimen is in a state of continuous increase, so the temperature detection information is detected, thereby improving the accuracy of the detected temperature detection information.

[0020] In a second aspect, the present application provides a concrete crack resistance detection system, which adopts the following technical solution: A concrete crack resistance detection system, comprising: An acquisition module is used to obtain the preparation completion trigger information and the detection time information; A memory for storing a program of a concrete crack resistance detection method as described in any one of the above items; The program in the memory can be loaded and executed by the processor to implement a concrete anti-cracking detection method as described in any one of the above items.

[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.

[0035] The embodiment of the present application discloses a method for detecting crack resistance of concrete specimens in the early and late stages of strength development, and specifically discloses a processing terminal, a strain force detection device and an induction device. The processing terminal is connected to the strain force detection device and the induction device through a data conductor, thereby realizing data interaction and control. When the processing terminal receives a trigger information indicating that preparation of the concrete specimen is completed, the processing terminal controls the strain force detection device to detect the strain force of the concrete specimen to determine the early strain data information, thereby essentially reflecting the cause of cracking of the concrete specimen when early cracks are not obvious, and detects the detection time information. When the detection time information meets the requirements of the induction time information, the processing terminal controls the induction device to induce cracking of the concrete specimen, and synchronously controls the strain force detection device to detect the strain force of the concrete specimen to determine the late strain data information, thereby drawing strain statistical chart information of the concrete specimen according to the early strain data information and the late strain data information, thereby improving the accuracy of anti-cracking detection of the concrete specimen.

[0036] Reference Figure 1 The present application discloses a method for detecting concrete crack resistance, comprising the following steps: Step S100: Acquire the preparation completion trigger information of the concrete specimen.

[0037] Among them, the concrete specimen refers to the concrete piece made by personnel in the concrete test mold for crack resistance test. The specific type and parameters are selected and determined by the operator according to the actual situation. The concrete test mold is built with a wedge-shaped steel beam to facilitate the subsequent induced cracking. The preparation completion trigger information refers to the trigger data for the initial solidification of the concrete specimen and the strain force detection. When the operator determines that the concrete specimen can be tested for strain force, the operator randomly sticks the strain force detection device on the surface of the concrete specimen, and the operator enters it in the graphical user interface of the processing terminal.

[0038] Step S101: according to the preparation completion trigger information, a preset strain force detection device is controlled to detect the strain force of the concrete specimen to determine the early strain data information.

[0039] After the processing terminal receives the preparation completion trigger information, the processing terminal responds to the preparation completion trigger information, thereby controlling the strain force detection device to start detecting the strain force of the concrete specimen in the early stage of strength development, and obtaining the early strain data information. The specific detection method is referred to Figure 2 At this time, the concrete specimens show high stress and high toughness, which are less directly reflected in actual cracking. Therefore, the strain force detection essentially reflects the cause of concrete specimen cracking.

[0040] The strain force detection device refers to a device used to detect the strain force of a concrete specimen, which can be composed of a number of bridge-type resistance sensors. The preliminary strain data information refers to a parameter table of the strain force of a concrete specimen changing with time. The strain force is detected by the strain force detection device, and the processing terminal determines the preliminary strain data information of the corresponding relationship between the strain force and time according to the detection time.

[0041] Step S102: Acquire the detection time information of the concrete specimen.

[0042] The detection time information refers to the detection time length of the concrete specimen, which is measured by a timer and sent to a processing terminal.

[0043] Step S103: determining whether the detection time information meets the requirements of the preset induction time information.

[0044] The induction time information refers to the shortest time for inducing cracking of concrete specimens by active means. The specific time is determined by the operator according to the actual situation and is usually set to 28 days. The requirement for the induction time information refers to the time length not less than that corresponding to the induction time information.

[0045] By processing the terminal, it is determined whether the time length corresponding to the detection time information is not less than the time length corresponding to the induction time information, thereby determining whether the time of the concrete specimen has reached the time for active induced cracking, providing data support for subsequent strain force detection.

[0046] Step S1031: If not, continue to obtain the detection time information of the concrete specimen for cyclic judgment.

[0047] Among them, if the processing terminal determines that the time length corresponding to the detection time information is lower than the time length corresponding to the induced time information, it indicates that the time length of the concrete specimen has not yet reached the time length for active induced cracking. Therefore, the detection time information of the concrete specimen continues to be detected, thereby continuing to pay attention to the time changes of the concrete specimen.

[0048] Step S1032: If the conditions are met, the preset induction device is controlled to induce the concrete specimen to crack, and the strain force detection device is controlled to detect the strain force of the concrete specimen to determine the later strain data information.

[0049] Among them, if the processing terminal determines that the time length corresponding to the detection time information is not less than the time length corresponding to the induction time information, it indicates that the time length of the concrete specimen has reached the time length for active induced cracking, thereby controlling the induction device to induce the concrete specimen to crack. The specific method is: controlling the pressure component in the induction device to apply force to the wedge-shaped steel beam in the concrete specimen, thereby actively fracturing the concrete specimen, and synchronously controlling the strain force detection device to detect the strain force in the cracking process of the concrete specimen to determine the later strain data information.

[0050] The induction device refers to a device that actively induces the cracking of a concrete specimen, including a wedge-shaped steel beam and a pressure assembly in the concrete specimen. After the pressure assembly applies force to the wedge-shaped steel beam, the wedge-shaped steel beam crushes the concrete specimen. The late strain data information refers to the change of the strain of the concrete specimen over time detected by the strain force detection device during the process of actively inducing cracking of the concrete specimen.

[0051] Step S10321: Draw the strain statistics chart information of the concrete specimen according to the early strain data information and the late strain data information.

[0052] Among them, the strain statistical chart information refers to a chart that reflects the stress change of the concrete specimen. After the processing terminal obtains the early strain data information and the later strain data information, the strain statistical chart information is drawn based on the time data corresponding to the early strain data information and the later strain data information as the horizontal axis and the strain force corresponding to the time as the vertical axis.

[0053] Reference Figure 2 The steps of controlling the preset strain force detection device to detect the strain force of the concrete specimen according to the preparation completion trigger information to determine the preliminary strain data information include: Step S200: starting the strain force detection device to detect the concrete specimen according to the preparation completion trigger information to determine the early strain data information and obtain the temperature detection information of the concrete specimen.

[0054] Among them, after the processing terminal receives the preparation completion trigger information, the processing terminal starts the strain force detection device, so that the strain force detection device detects the concrete specimen to determine the early strain data information. A large amount of heat will be generated during the hydration heat process in the early stage of strength development of the concrete specimen, which may cause the strain force detection device to detect inaccurately. Therefore, the temperature detection information of the concrete specimen is detected to provide data support for the subsequent control of the strain force detection device to detect the strain force of the concrete specimen.

[0055] Temperature detection information refers to the temperature detection value of the concrete specimen, which is detected by the temperature sensor installed on the strain force detection device and sent to the processing terminal. The specific detection method is referred to Figure 7 steps.

[0056] Step S201: obtaining the influencing temperature information of the strain force detection device.

[0057] Among them, the influencing temperature information refers to the temperature value that affects the resistance of the bridge resistor sensor in the strain force detection device. The specific value is input into the processing terminal by the operator according to the specific situation of the bridge resistor sensor. If a temperature compensation resistor is added to the bridge resistor sensor, the corresponding influencing temperature will be higher.

[0058] Step S202: Determine whether the temperature detection information meets the requirements for influencing temperature information.

[0059] The requirement for influencing temperature information refers to not being lower than the temperature value corresponding to the influencing temperature information. The processing terminal determines whether the temperature value corresponding to the temperature detection information is not lower than the temperature value corresponding to the influencing temperature information, thereby determining whether the temperature on the surface of the concrete specimen may affect the bridge resistance sensor in the strain force detection device, and providing data support for the subsequent control of the strain force detection device.

[0060] Step S2021: If not, continue to control the strain force detection device to detect the concrete specimen to determine the early strain data information, and continue to obtain the temperature detection information of the concrete specimen for cyclic judgment.

[0061] Among them, if the processing terminal determines that the temperature value corresponding to the temperature detection information is lower than the temperature value corresponding to the influencing temperature information, it indicates that the temperature of the surface of the concrete specimen will not affect the detection of the strain force detection device. Therefore, the strain force detection device continues to be controlled to detect the concrete specimen to determine the preliminary strain data information, and continues to detect the temperature detection information of the concrete specimen, so as to continue to pay attention to the temperature changes of the concrete specimen.

[0062] Step S2022: If the conditions are met, the strain force detection device is controlled to detect the concrete specimen according to a preset temperature compensation method to determine the early strain data information.

[0063] Among them, if the processing terminal determines that the temperature value corresponding to the temperature detection information is not lower than the temperature value corresponding to the influencing temperature information, it indicates that the temperature of the surface of the concrete specimen will affect the detection of the strain force detection device. Therefore, the strain force detection device is controlled according to the temperature compensation method to detect the concrete specimen to determine the early strain data information. The specific method is referred to Figure 3 steps, thereby reducing the influence of the surface temperature of the concrete specimen on the strain force detection device and ensuring the accuracy of the detection.

[0064] The temperature compensation method refers to a method of actively lowering the temperature to assist the strain force detection device in detection. The operator stores it in the processing terminal. For specific methods, refer to Figure 3 steps.

[0065] Reference Figure 3 The steps of controlling the strain force detection device to detect the concrete specimen according to the preset temperature compensation method to determine the preliminary strain data information include: Step S300: controlling a preset temperature compensation device to perform temperature compensation on the strain force detection device, and controlling the strain force detection device to detect the concrete specimen to determine basic strain data information.

[0066] When the processing terminal determines that the temperature value corresponding to the temperature detection information is not lower than the temperature value corresponding to the influencing temperature information, the processing terminal controls the temperature compensation device to perform temperature compensation on the strain force detection device. The specific method is as follows: Figure 4 steps, thereby reducing the temperature of the strain force detection device, and at the same time controlling the strain force detection device to detect the concrete specimen to determine the basic strain data information, providing array support for the subsequent determination of the preliminary strain data information.

[0067] The temperature compensation device refers to a device used to perform temperature compensation for the strain force detection device, and a cooling fan or semiconductor can be used to cool the bridge resistance sensor. The basic strain data information refers to the change of the strain force detected by the strain force detection device over time when the temperature compensation device cools the strain force detection device.

[0068] Step S301: obtaining device temperature information of the strain force detection device.

[0069] The device temperature information refers to the temperature value of the bridge resistor sensor in the strain force detection device, which is obtained by detecting the bridge resistor sensor by a temperature sensor installed in the strain force detection device.

[0070] Step S302: Determine whether the device temperature information meets the requirements for influencing temperature information.

[0071] The requirements for the temperature information affecting this step are consistent with those for the temperature information affecting step S202, and are not described in detail here. The processing terminal determines whether the temperature value corresponding to the device temperature information is not lower than the temperature value corresponding to the temperature information affecting the device, thereby determining whether the temperature compensation device has lowered the temperature of the strain force detection device to a normal detection temperature value, and providing data support for the subsequent determination of the early strain data information.

[0072] Step S3021: If not, the basic strain data information is defined as the preliminary strain data information, and the temperature compensation device is continuously controlled to perform temperature compensation on the strain force detection device.

[0073] Among them, if the processing terminal determines that the temperature value corresponding to the device temperature information is lower than the temperature value corresponding to the influencing temperature information, it indicates that the temperature compensation device has lowered the temperature of the strain force detection device to the temperature value for normal detection. Therefore, the basic strain data information is directly defined as the preliminary strain data information, and the temperature compensation device continues to be controlled to perform temperature compensation on the strain force detection device to prevent the temperature of the strain force detection device from rising again and causing inaccurate detection.

[0074] Step S3022: If it is in compliance, correction is performed according to the basic strain data information to determine the previous strain data information, and the temperature compensation device is continuously controlled to perform temperature compensation on the strain force detection device.

[0075] Among them, if the processing terminal determines that the temperature value corresponding to the device temperature information is not lower than the temperature value corresponding to the influencing temperature information, it means that the temperature compensation device has not lowered the temperature of the strain force detection device to the normal detection temperature value. Therefore, the basic strain data information is corrected to determine the preliminary strain data information. The specific method is referred to Figure 6 and continue to control the temperature compensation device to perform temperature compensation on the strain force detection device, so that the temperature of the strain force detection device develops toward a trend close to a normal temperature, thereby reducing the influence of temperature on the detection accuracy of the strain force detection device.

[0076] Reference Figure 4 The step of controlling the preset temperature compensation device to perform temperature compensation on the strain force detection device includes: Step S400: Acquire temperature abnormality sequence number information of temperature detection information.

[0077] The temperature anomaly serial number information refers to the serial number of the temperature sensor that detects the temperature detection information when it is determined that the temperature detection information exceeds the influencing temperature information. The temperature anomaly serial number information is determined by the processing terminal identifying the identification code in the temperature detection information.

[0078] Step S401: determining temperature compensation position information according to temperature anomaly sequence number information and preset sequence number position relationship information.

[0079] Among them, the serial number position relationship information refers to a database storing the corresponding relationship between the serial number and the position. Different positions have corresponding device serial numbers. When the operator pastes the strain force detection device on the concrete specimen, the operator stores the serial number of the pasted device in the database after matching the position. The temperature compensation position information refers to the position on the concrete specimen where the temperature needs to be lowered. The processing terminal inputs the serial number corresponding to the temperature abnormality serial number information into the database corresponding to the serial number position relationship information for matching and output.

[0080] Step S402: controlling the temperature compensation device to perform temperature compensation on the strain force detection device according to the temperature compensation position information.

[0081] Among them, after the processing terminal determines the temperature compensation position information, if the temperature compensation device is a movable device, the linear module is controlled to move the temperature compensation device to the position corresponding to the temperature compensation position information, so that the temperature compensation device reduces the temperature of the strain force detection device; if the temperature compensation device is a fixed device, the temperature compensation device at the position corresponding to the temperature compensation position information is directly controlled to reduce the temperature of the strain force detection device, thereby reducing the influence of temperature on the strain force detection device. The specific method is referred to Figure 5 steps.

[0082] Reference Figure 5 The step of controlling the temperature compensation device to perform temperature compensation on the strain force detection device according to the temperature compensation position information includes: Step S500: starting a corresponding temperature compensation device according to the temperature compensation position information, and analyzing the device temperature information and the influencing temperature information to determine the temperature deviation information.

[0083] Among them, after the processing terminal determines the temperature compensation position information, the processing terminal starts the temperature compensation device at the position corresponding to the temperature compensation position information, and determines the temperature deviation information according to the device temperature information and the influencing temperature information, providing data support for the subsequent control of the temperature compensation device for temperature compensation.

[0084] The temperature deviation information refers to the temperature value that the strain force detection device needs to lower, and is obtained by calculating the difference between the temperature corresponding to the device temperature information and the temperature corresponding to the influencing temperature information by the processing terminal.

[0085] Step S501: determining system parameter information according to temperature detection information and preset temperature parameter relationship information.

[0086] Among them, temperature parameter relationship information refers to a database that stores the corresponding relationship between heat source temperature parameters and system parameters. The system parameters include proportional gain coefficient, integral gain coefficient and differential gain coefficient. The proportional gain coefficient is proportional to the heat source temperature. The higher the heat source temperature, the larger the proportional gain coefficient, thereby quickly responding to the influence of the heat source; the integral gain coefficient is inversely proportional to the heat source temperature. The higher the heat source temperature, the smaller the integral gain coefficient is required to avoid over-adjustment; the differential gain coefficient is proportional to the heat source temperature. The higher the heat source temperature, the higher the differential gain coefficient, which helps the system quickly adapt to temperature changes. The operator matches the heat source temperature to the system parameters one by one according to the results of the actual test and stores them in the database.

[0087] System parameter information refers to system parameters used to control the temperature compensation device for temperature compensation, including proportional gain coefficient, integral gain coefficient and differential gain coefficient. The processing terminal matches and outputs the temperature corresponding to the temperature detection information into the database corresponding to the temperature parameter relationship information.

[0088] Step S502: Analyze the system parameter information and the temperature deviation information to determine the temperature control power information.

[0089] Among them, the temperature control power information refers to the power of controlling the temperature compensation device for temperature compensation, which is determined by the processing terminal after analysis based on the system parameter information and the temperature deviation information. The specific analysis method is: first, determine that the time variation function of the temperature difference corresponding to the temperature deviation information is the error function, and multiply the proportional gain coefficient in the system parameter information by the error function to obtain the proportional gain term; then, integrate the error function from 0 to t, and then multiply it by the integral gain coefficient to obtain the integral gain term; finally, differentiate the error function with respect to t, and multiply it by the differential gain coefficient to obtain the differential gain term; and sum the proportional gain term, the integral gain term, and the differential gain term to obtain the temperature control power information.

[0090] Step S503: controlling the started temperature compensation device according to the temperature control power information to perform temperature compensation on the strain force detection device.

[0091] Among them, after the processing terminal obtains the temperature control power information, the processing terminal controls the temperature compensation device according to the power corresponding to the temperature control power information to perform temperature compensation on the strain force detection device with the temperature corresponding to the power, thereby quickly and accurately cooling the strain force detection device, thereby improving the accuracy and efficiency of cooling.

[0092] Reference Figure 6 The steps of correcting the basic strain data information to determine the previous strain data information include: Step S600: Analyze the basic strain data information to determine output voltage information.

[0093] The output voltage information refers to the voltage directly output by the bridge resistor sensor in the strain force detection device when detecting the basic strain data information, and is obtained by the processing terminal identifying the voltage corresponding to the strain force in the database according to the strain force corresponding to the basic strain data information.

[0094] Step S601: Analyze the device temperature information and the influencing temperature information to determine the correction temperature information.

[0095] The correction temperature information refers to the temperature value that needs to be lowered to correct the device temperature to the normal temperature, and is obtained by calculating the difference between the device temperature information and the influencing temperature information by the processing terminal.

[0096] Step S602: Analyze the output voltage information, the correction temperature information and the preset temperature coefficient information to determine the correction voltage information.

[0097] The temperature coefficient information refers to the relationship between temperature and voltage, that is, the voltage corresponding to the unit temperature increase is determined by the operator according to the specific situation of the strain force detection device. The correction voltage information refers to the voltage that the bridge resistor sensor in the strain force detection device should output after eliminating the temperature effect. The processing terminal first calculates the product between the temperature corresponding to the correction temperature information and the coefficient corresponding to the temperature coefficient information to obtain the additional increased voltage, and then calculates the difference between the voltage corresponding to the output voltage information and the additional increased voltage to obtain the correction voltage information.

[0098] Step S603: Analyze the corrected voltage information to determine the early strain data information.

[0099] After the processing terminal determines the correction voltage information, the processing terminal inputs the voltage corresponding to the correction voltage information into the database to match the strain force corresponding to the voltage, thereby obtaining more accurate preliminary strain data information.

[0100] Reference Figure 7 , the steps of obtaining the temperature detection information of the concrete specimen include: Step S700: Obtaining the standing time information of the concrete specimen.

[0101] The standing time information refers to the standing time value after the concrete specimen is made, which is counted by the timer and sent to the processing terminal.

[0102] Step S701: Determine whether the static time information meets the preset impact time information requirement.

[0103] The impact time information refers to the maximum time that the temperature will affect the strain force detection device. Usually, the hydration heat of concrete will be completed within three to seven days, so seven days is determined as the impact time information. The requirement for the impact time information is not less than the time value corresponding to the impact time information.

[0104] The processing terminal determines whether the time corresponding to the static time information is not less than the time value corresponding to the impact time information, thereby determining whether the temperature of the concrete specimen will affect the strain force detection device.

[0105] Step S7011: If it meets the requirements, the preset temperature detection device is controlled to stop detecting the temperature detection information of the concrete specimen.

[0106] If the processing terminal determines that the time corresponding to the static time information is not less than the time value corresponding to the impact time information, it indicates that the static time of the concrete specimen has exceeded the rising period of the temperature of the concrete specimen, and the temperature of the concrete specimen is stable at this time, so the temperature detection device is controlled to stop detecting the temperature detection information of the concrete specimen. The temperature detection device refers to a device used to detect the concrete specimen, and a temperature sensor can be used.

[0107] Step S7012: If not, controlling a preset temperature detection device to detect the concrete specimen according to preset detection frequency information to determine temperature detection information.

[0108] Among them, if the processing terminal determines that the time corresponding to the standing time information is lower than the time value corresponding to the impact time information, it indicates that the standing time of the concrete specimen is still in the rising period of the temperature of the concrete specimen. At this time, the temperature of the concrete time will affect the strain force detection device. Therefore, the temperature detection device is controlled according to the frequency corresponding to the detection frequency information to detect the concrete specimen to determine the temperature detection information.

[0109] The detection frequency information refers to the frequency of the temperature detection device detecting the concrete specimen, and the specific value is determined by the operator according to the actual situation. The temperature detection device in this step is the same as the temperature detection device in step S7011, and will not be described in detail here.
