Description

Technical Field

[0001] The present application relates to the technical field of steel bar detection, and in particular to a method and system for monitoring temperature conditions during automatic tensile testing of threaded steel bars. Background Art

[0002] Rebar is a steel bar with ribs on the surface, also known as ribbed steel bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length. The shape of the transverse ribs is spiral, herringbone, and crescent. It is expressed in millimeters of nominal diameter. The nominal diameter of ribbed steel bars is equivalent to the nominal diameter of plain round steel bars with equal cross-sections. The nominal diameter of steel bars is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, and 40 mm. The full diameter is 6, 8, 10, 12, 14, 16, 18, 20, 22, 25, 28, 32, 36, 40, and 50. Ribbed steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, ribbed steel bars have a greater bonding ability with concrete, so they can better withstand the effects of external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. Due to the effect of the ribs, deformed steel bars have a greater bonding ability with concrete, so they can better withstand the effects of external forces. Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.

[0003] Since steel bars are widely used in various building structures, the quality of steel bars needs to be tested. However, in the existing technology, the automatic tensile test system directly tests after sampling with a mechanical arm, and no temperature measurement system is introduced or added to the sample to be tested. The experimental temperature condition is room temperature, and the temperature will affect the yield strength and tensile strength. Therefore, the problem of inaccurate experiment is caused. Summary of the invention

[0004] In view of this, the purpose of this application is to provide a method and system for monitoring temperature conditions during automatic tensile testing of threaded steel bars, which for the first time adds sample, laboratory temperature, and laboratory humidity detection to the automatic physical property inspection system to ensure standard laboratory testing conditions and the reliability of the inspection.

[0007] Comparing the actual temperature with the preset ideal temperature of the experiment to obtain the temperature difference between the actual temperature and the preset ideal temperature of the experiment;

[0008] If the temperature difference is less than a threshold value, a stretching test is performed on the target to be detected to obtain detection data;

[0009] A test report is generated based on the test data, the ambient temperature and the ambient humidity.

[0010] Optionally, the method further includes:

[0011] If the temperature difference is greater than or equal to a threshold, estimating a temperature change curve of the target to be measured based on the ambient temperature and the ambient humidity;

[0028] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0029] First, the application scenarios to which this application can be applied are introduced. This application can be applied to steel bar detection scenarios.

[0030] After research, it was found that in the existing technology, the automatic tensile test system directly tests after sampling through a mechanical arm, and no temperature measurement system for the sample to be tested was introduced or added. The experimental temperature condition is room temperature, and the temperature will affect the yield strength and tensile strength. Therefore, the problem of inaccurate experiments is caused.

[0031] Based on this, the embodiment of the present application provides a method and system for monitoring temperature conditions during the automatic tensile test of threaded steel bars, which adds the detection of samples, laboratory temperature, and laboratory humidity to the automatic physical property inspection system to ensure the standard conditions of laboratory testing and the reliability of the inspection. By measuring the sample temperature and recording the laboratory temperature and humidity, the sample temperature, laboratory temperature, and laboratory humidity corresponding to each test sample can be monitored, and test condition parameters can also be provided for performance difference analysis.

[0032] like Figure 1 As shown in , the temperature condition monitoring method during the automatic tensile test of threaded steel bars provided in the embodiment of the present application includes:

[0033] S101, obtaining the actual temperature of the target to be measured and the ambient temperature and humidity of the environment in which the target to be measured is located;

[0034] S102, comparing the actual temperature with a preset ideal temperature of the experiment to obtain a temperature difference between the actual temperature and the preset ideal temperature of the experiment;

[0035] S103, if the temperature difference is less than a threshold, performing a stretching test on the target to be detected to obtain detection data;

[0036] S104: forming a test report based on the test data, the ambient temperature and the ambient humidity.

[0037] In a possible implementation, the method further includes:

[0038] If the temperature difference is greater than or equal to a threshold, estimating a temperature change curve of the target to be measured based on the ambient temperature and the ambient humidity;

[0039] A target time for detecting the target to be detected is determined according to the temperature change curve, and the target to be detected is detected at the target time.

[0040] In a possible implementation, the step of estimating the temperature change curve of the target to be measured based on the ambient temperature and the ambient humidity includes:

[0041] Acquiring the thermal conductivity of the object to be measured based on the type information of the object to be measured;

[0042] A temperature change curve of the target to be measured is estimated based on the thermal conductivity, the ambient temperature, and the ambient humidity.

[0043] In a possible implementation, the present application provides a temperature condition monitoring system for automatic tensile testing of threaded steel bars, comprising:

[0044] The information acquisition module 201 is used to acquire the actual temperature of the target to be measured and the ambient temperature and humidity of the environment in which the target to be measured is located;

[0045] A calculation module 202 is used to compare the actual temperature with a preset ideal temperature of the experiment to obtain a temperature difference between the actual temperature and the preset ideal temperature of the experiment;

[0046] A detection module 203 is used to perform a stretching test on the target to be detected to obtain detection data if the temperature difference is less than a threshold value;

[0047] The integration module 204 is used to form a detection report based on the detection data, the ambient temperature and the ambient humidity.

[0048] In a possible implementation, the system further includes:

[0049] The delay module is used to estimate the temperature change curve of the target to be measured based on the ambient temperature and the ambient humidity if the temperature difference is greater than or equal to a threshold; determine the target time for detecting the target to be measured according to the temperature change curve, and detect the target to be detected at the target time.

[0050] In a possible implementation, the information acquisition module may use an infrared temperature measurement sensor.

[0051] Exemplarily, a temperature detection function is added to the position of the robot arm close to the sample, and samples that do not meet the test requirements cannot be tested. That is, if the temperature difference is greater than a threshold, an alarm is triggered, and other samples are tested first. Then, combined with the temperature reduction curve, the time required for the temperature reduction is predicted, and the test is restarted after the temperature meets the requirements.

[0052] After adding sample temperature detection, the sample detection temperature can be guaranteed, thereby ensuring the accuracy of the inspection. There is no need to manually measure the sample temperature, record the laboratory temperature and humidity. The sample temperature, laboratory temperature and laboratory humidity corresponding to each test sample can be monitored, and the test condition parameters can also be provided for performance difference analysis.
