[0029] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will provide a clear and complete description of the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0030] In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "plurality" is at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.

[0031] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0032] In this application, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it can mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is "above," "above," or "above" a second feature, it can mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it can mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0033] The parts under test are typically critical load-bearing components, potentially presenting significant safety risks during their use. Therefore, this device is required before every product leaves the factory. For example, the parts under test can be weighed welded structural components. After production, each part undergoes a load test to ensure it meets load requirements. Using this device ensures product quality, enhances testing capabilities, and improves efficiency, making the development of this system essential.

[0034] However, as the production efficiency of the DUT increases and the production pace accelerates, the pace of loading tests on the DUT also needs to be accelerated. The data processing work after the test is completed is extremely complicated, which ultimately leads to delayed completion of the test report. This problem has become one of the factors restricting the normal flow of products.

[0035] Specifically, currently, when performing loading tests on the product under test, the oil source is mainly controlled by a manual tensile pump. When using multiple oil sources for graded pressurization, multiple people are required to operate multiple oil pumps at the same time, and the pressurization process is greatly affected by manual operation. At the same time, the direct data collected after the loading is completed is the strain value. This data needs to be calculated by technicians through complex formulas before it can be converted into the stress data required by the process, making it difficult to achieve on-site data identification.

[0036] In order to improve the efficiency of loading tests and solve the problems of delayed test data processing and test report completion, an embodiment of the present application provides a system and method for automatic loading and data collection and analysis. The scheme of the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.

[0037] Figure 1 This is a schematic diagram of a system for automatically loading and performing data acquisition and analysis provided in an embodiment of the application.

[0038] Reference Figure 1 As shown, in the first aspect, the embodiment of the present application provides a system for automatic loading and data acquisition and analysis, including a power source 100, a hydraulic cylinder 300, a reversing valve 200, a controller 500 and a data acquisition device 400. Among them, the power source 100 is used to provide high-pressure medium to the hydraulic cylinder 300, and the output end of the hydraulic cylinder 300 is connected to the test point of the test piece; one end of the reversing valve 200 is connected to the hydraulic cylinder 300, and the other end is connected to the power source 100, and the reversing valve 200 is used to control the action of the hydraulic cylinder 300; the controller 500 and the data acquisition device 400 are electrically connected, and the data acquisition device 400 is connected to the power source and the test piece respectively. The controller 500 obtains the liquid pressure data at the power source 100 and the detection data at the test piece through the data acquisition device 400. Compared with the existing technology, the controller 500 obtains the pressure data at the power source 100 and the detection data at the test piece through the data acquisition device 400 and performs automatic calculation and analysis, which greatly reduces the time for subsequent data processing and improves the detection efficiency. It can then judge the quality parameters of the product in the first time, improve product quality reliability, and reduce the risk of zeroing.

[0039] In some examples, the hydraulic cylinder 300 is configured as an oil cylinder; the power source 100 is configured as a high-pressure oil source; and the controller 500 is configured as a PLC control unit.

[0040] In addition, in some examples, there are multiple hydraulic cylinders 300, and the multiple hydraulic cylinders 300 are respectively connected to corresponding test points of the test piece to perform loading tests on different positions of the test piece.

[0041] For example, in some other examples, there are multiple power sources 100, and the multiple power sources 100 are respectively connected to the hydraulic cylinder 300. Multiple power sources 100 can be operated by one person, which greatly saves labor costs.

[0042] In some examples, the data acquisition device 400 includes a process control acquisition computer and multiple detection sensors; the controller 500 is electrically connected to the process control acquisition computer, which is electrically connected to the detection sensors. The multiple detection sensors are respectively provided on the power source 100 and the test piece, and are used to detect liquid pressure data at the power source 100 and detection data at the test piece. Exemplarily, the detection data at the test piece includes strain values, voltage values, current values, and angle values.

[0043] In addition, in some examples, the system for automatically loading and performing data acquisition and analysis also includes a data analyzer, which is electrically connected to the controller 500 and is equipped with data calculation and analysis software. This allows the controller 500 to quickly and automatically calculate and analyze the liquid pressure data at the power source 100 and the test data of the test piece obtained by the data acquisition device 400. In other examples, the controller 500 can directly perform data calculation and analysis.

[0044] Figure 2 This is a flowchart of a method for automatically loading and collecting data provided in an embodiment of the application.

[0045] Secondly, refer to Figure 2 As shown, the present application also provides a method for automatically loading and collecting data, using the system for automatically loading and performing data collection and analysis as in the first aspect to perform a loading test on the device under test.

[0046] The specific steps include:

[0047] S100: Controlling the hydraulic pressure of the power source 100 to control the cylinder pulling pressure;

[0048] S200: The controller 500 collects the liquid pressure data of the power source 100 through the data acquisition device 400. When the liquid pressure data meets the preservation conditions, the controller 500 stores the liquid pressure data and the detection data of the tested component and analyzes and generates a data report.

[0049] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on the several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.
