Description

Technical Field

[0001] The present invention relates to the field of artificial intelligence technology, and more specifically, to a test system for the porosity of a filter pipe. Background Art

[0002] As an essential tool in various water diversion and pumping projects, the main function of a filter pipe is to filter out impurities in water to improve the water quality of the water source. With the continuous improvement of people's living standards, the filter pipe plays an increasingly important role. The porosity of the filter pipe, as an important indicator to measure the performance of the filter pipe, has various functions. Therefore, it is necessary to collect and test the porosity of the filter pipe to improve the filtration efficiency of the filter pipe.

[0003] The traditional test system for the porosity of a filter pipe calculates the porosity based on the difference between the total volume and the solid volume of the material, including a collection module, a porosity analysis module, and a human-computer interaction module. Among them, the collection module is used to collect the weights of the filter pipe in the dry state and after immersion in water; the porosity analysis module is used to analyze the collected data, and obtain the porosity by the difference between the two weights and in combination with the water density; the human-computer interaction module is used for human-computer interaction with the porosity obtained by the porosity analysis module.

[0004] However, in actual use, there are still some disadvantages. For example, although the collection module collects data of the filter pipe in different states, the collected data is still not comprehensive. When the materials used for the filter pipe are different, the pore sizes of the filter pipe are different, and the pore numbers of the filter pipe are different, it will also affect the porosity. Therefore, only using the weights of the filter pipe in different states for analysis in the porosity analysis module, the performance and water permeability of the filter pipe obtained are not accurate and comprehensive enough, and more dimensional data is needed to support the analysis of the porosity.

[0041] In this embodiment, it should be specifically noted that the fluid data acquisition module includes a fluid control unit and a fluid data acquisition unit. The fluid control unit includes a fluid pump, a flowmeter, and a valve, which are used to inject fluid into the filter pipe and control the flow rate and pressure of the fluid.
