Description

Technical Field

[0001] The invention relates to the technical field of intelligent water repellency measuring instruments, and in particular to an intelligent water repellency measuring instrument based on a sensor. Background Art

[0002] In production and scientific research, it is of great significance to accurately measure the hydrophobicity of materials. Traditional methods for measuring hydrophobicity have problems such as complex operation, low precision, and long time consumption, which are difficult to meet the needs of modern industry for efficient and accurate detection. Therefore, it is of great practical value to develop an intelligent measuring instrument system based on sensors to achieve rapid and accurate measurement of hydrophobicity.

[0003] For example, the Chinese patent publication number CN104568676A discloses a method and device for testing the hydrophobicity of a material, including: dropping a liquid drop onto a material and placing a reference object on the material being tested. Taking photos of the material being tested, as well as the liquid droplets and the reference object on the material being tested, to obtain an image. Calculating the number of droplet pixels N and the number of reference pixel N0 occupied by the droplet and the reference object in the image respectively. Calculating the actual projection area DA from the droplet to the material being tested: wherein S0 is the actual projection area set from the reference object to the material being tested. The hydrophobicity of the material being tested is judged based on the size of the actual projection area DA. Compared with the prior art, the hydrophobicity of the material tested in the present invention is simpler and more accurate.

[0004] The above existing technologies still have the following problems: 1. The adverse effects of water pollution in the hydrophobicity intelligent meter on its water cycle are not deeply analyzed, which increases the error of water cycle function analysis and reduces the accuracy of the assessment of whether the overall quality of the hydrophobicity intelligent meter meets the standards.

[0005] 2. Multiple experimental groups were not set up, that is, the rock plate angle adjustment experimental group and the water spray flow rate adjustment experimental group were not set up. The measurement accuracy of the intelligent hydrophobicity measuring instrument at each rock plate angle and each water spray flow rate was not analyzed. It was impossible to comprehensively evaluate the performance of the measuring instrument under different conditions, and it was impossible to accurately judge the size and source of the measurement error, which reduced the reliability of the experimental conclusions and could not provide data support for subsequent effective improvement measures.

[0006] 3. In the rock plate angle adjustment experiment group, the influence of the rock plate angle maintenance on the measurement accuracy was not deeply analyzed. In the water spray flow adjustment experiment group, the influence of the water pressure stability and the water spray range during water spraying on the measurement accuracy was not deeply analyzed. It is impossible to accurately evaluate the influence of angle maintenance, water pressure stability and water spray range on the measurement accuracy, which limits the scope of interpretation of the experimental results and reduces the practical value of the experimental results. Summary of the invention

[0007] In view of this, in order to solve the problems raised in the above background technology, a sensor-based intelligent water repellency measuring instrument is now proposed.

[0008] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides a sensor-based intelligent hydrophobicity measuring instrument, including: a water circulation function evaluation module, which is used to record the target hydrophobicity intelligent measuring instrument as the target measuring instrument, collect the water inlet flow and outlet flow of the water circulation system in the target measuring instrument per unit time, and at the same time collect the number of suspended matter and the volume of each suspended matter in the water body of the target measuring instrument, evaluate whether the function of the water circulation system in the target measuring instrument meets the standard, and provide feedback if it does not meet the standard.

[0009] The rock slab angle adjustment test module is used to record the target exterior wall insulation rock wool board as the target rock slab, extract the water repellency of the target rock slab corresponding to each test at each angle collected by the target measuring instrument under the same water spray flow rate, and monitor the angle of the target rock slab at each angle corresponding to each monitoring time point, and analyze the measurement accuracy of the target measuring instrument in the rock slab angle test.

[0010] The water spray flow adjustment test module is used to extract the hydrophobicity of the target rock slab corresponding to each test at each water spray flow rate collected by the target measuring instrument at a fixed angle, while monitoring the water spray information corresponding to the target rock slab at each water spray flow rate, and analyzing the measurement accuracy of the target measuring instrument in the water spray flow test.

[0011] The database is used to store the influencing factors of the functional goodness evaluation corresponding to the unit cleanliness, store the standard water repellency of the target rock slab at various angles under the same water spray flow rate, and store the standard water repellency of the target rock slab at various water spray flow rates under a fixed angle.

[0013] The overall quality assessment module of the measuring instrument is used to assess whether the overall quality of the target measuring instrument meets the standards, and provide feedback if it does not meet the standards.

[0014] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: (1) The present invention reduces the error of water circulation function analysis and improves the accuracy of the assessment of whether the overall quality of the intelligent hydrophobicity measuring instrument meets the standards by combining the number of suspended matter and the volume of each suspended matter in the water body in the intelligent hydrophobicity measuring instrument to conduct an in-depth analysis of the adverse effects on its water circulation.

[0015] (2) The present invention sets up multiple experimental groups, namely, a rock plate angle adjustment experimental group and a water spray flow rate adjustment experimental group, to analyze the measurement accuracy of the intelligent hydrophobicity measuring instrument at each rock plate angle and each water spray flow rate, thereby helping to comprehensively evaluate the performance of the measuring instrument under different conditions, accurately determine the size and source of the measurement error, improve the reliability of the experimental conclusions, and provide data support for subsequent effective improvement measures.
