Description

Technical Field

[0001] The present invention relates to the technical field of ceramic membranes, and in particular to a product identification system and method based on ceramic membrane production. Background Art

[0002] Tubular inorganic ceramic membrane is a membrane separation component with a special structure. It has the characteristics of high temperature resistance, good chemical stability, strong wear resistance, uniform pore size, and easy cleaning. It is often used in the fields of chemical, biological, food and water treatment.

[0003] When the tubular inorganic ceramic membrane is used in the field of water treatment, the honeycomb holes of the tubular inorganic ceramic membrane with honeycomb holes in the cross section will be filled with the liquid to be treated. The liquid is filtered by the tubular inorganic ceramic membrane by pressurization, so that impurities in the water are blocked in the honeycomb holes, and the part of the liquid that can penetrate the tubular inorganic ceramic membrane seeps out from the surface of the tubular inorganic ceramic membrane, thereby achieving a filtering effect;

[0004] However, the production of tubular inorganic ceramic membranes and their quality inspection currently mainly rely on test methods such as pore size distribution measurement, porosity detection, and transmittance test. The test results can only reflect one aspect of the characteristics of the tubular inorganic ceramic membrane. If the comprehensive performance of the tubular inorganic ceramic membrane needs to be analyzed, a large amount of data statistics, calculations, and analysis are still required to obtain the results. The efficiency is poor and it is easy to make mistakes when there is a lot of data, making it impossible to analyze the comprehensive performance of the tubular inorganic ceramic membrane. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a product identification system and method based on ceramic membrane production, which solves the technical problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] In a first aspect, a product identification system based on ceramic membrane production includes:

[0008] The control terminal is the main control terminal of the system and is used to issue execution commands;

[0009] Inspection module, used to contact the ceramic membrane and display the water filtration status data of the ceramic membrane;

[0010] The acquisition module is used to collect the ceramic membrane water filtration status data displayed on the inspection module;

[0011] An analysis module is used to receive the ceramic membrane water filtration state data collected by the collection module, and analyze the ceramic membrane water filtration performance based on the ceramic membrane water filtration state data;

[0012] The analysis logic of the ceramic membrane water filtration performance in the analysis module is expressed as:

[0013]

[0014] Where: k is the difference in water filtration performance of the three groups of ceramic membrane water filtration state data corresponding to the source position; f i 、f i+1 、f i+2 is the average gray value of the i-th, i+1-th and i+2-th groups of ceramic membrane water filtration status data; CITY(i,i+1) is the consistency of the i-th and i+1-th groups of ceramic membrane water filtration status data; CITY(i+1,i+2) is the consistency of the i+1-th and i+2-th groups of ceramic membrane water filtration status data; K is the performance value of the ceramic membrane water filtration performance; m is the set of all groups k of the ceramic membrane water filtration status data obtained based on formula (1); k j is the water filtration performance difference of group j;

[0015] Among them, the larger the ceramic membrane water filtration performance value K is, the worse the ceramic membrane water filtration performance is, and vice versa, the better the water filtration performance is. When the ceramic membrane water filtration status data is used based on formula (1), each set of ceramic membrane water filtration status data is used twice;

[0016] A determination module is used to obtain the analysis results of the water filtration performance of the ceramic membrane in the analysis module, and determine whether the ceramic membrane is qualified based on the analysis results of the water filtration performance of the ceramic membrane;

[0017] A sniffing module is used to monitor the determination result of the determination module, and when the determination result of the determination module is negative, sniff the position where the defect exists on the surface of the ceramic membrane;

[0018] The control terminal is interactively connected to a test module via a wireless network, the test module is interactively connected to an indication unit and a push unit at a lower level via a wireless network, the test module is interactively connected to a collection module via a wireless network, the collection module is connected to the indication unit via a wireless network, the collection module is interactively connected to an analysis module via a wireless network, the analysis module is interactively connected to a logic unit at a lower level via a wireless network, the analysis module is interactively connected to a determination module and a sniffing module via a wireless network, and the determination module is interactively connected to the logic unit via a wireless network.

[0019] Furthermore, the inspection module is composed of submodules, including:

[0020] The indicating unit is used to indicate the degree of water filtration of the ceramic membrane. When the ceramic membrane leaks out filtered water, it senses the humidity on the surface of the ceramic membrane and shows a color change;

[0021] A pushing unit, used to push the indicating unit to be close to or away from the surface of the ceramic membrane;

[0022] Among them, the indicating unit is integrated with a humidity sensor and an LED display screen. The humidity sensor is pushed by the pushing unit until it is in contact with the surface of the ceramic membrane, and the humidity on the surface of the ceramic membrane is detected. The detected humidity on the surface of the ceramic membrane is represented by a numerical value, and the numerical value representing the humidity is fed back to the LED display screen. Display logic is set in the LED display screen. The LED display screen displays the humidity based on the display logic and the received numerical value representing the humidity. During the operation stage of the inspection module, the inside of the ceramic membrane is filled with the liquid to be filtered. After the humidity sensor is pushed by the pushing unit to be in contact with the surface of the ceramic membrane, the liquid injected into the ceramic membrane is pressurized, so that the liquid stored in the porous structure inside the ceramic membrane is filtered out through the ceramic membrane and contacts the humidity sensor.

[0023] Furthermore, the display logic set in the LED display screen is: set a group of colors, receive a numerical value representing humidity, so that when the LED display screen receives a larger numerical value representing humidity, the displayed color becomes darker, and vice versa, the displayed color becomes lighter, and the color display result of the LED display screen is the ceramic membrane water filtration status data;

[0024] A group of indicating units and a group of pushing units are recorded as a group of inspection modules, and the inspection modules are provided in a plurality of groups, and the plurality of inspection modules are distributed in an equidistant ring shape. When the inspection module contacts the ceramic membrane, the ceramic membrane stands at the center of the inspection module distributed in an annular shape. When the humidity sensor of the inspection module contacts the surface of the ceramic membrane, the sensing end of the humidity sensor is close to the porous inner wall of the ceramic membrane.

[0025] Among them, no less than two groups of humidity sensors and one group of LED display screens are recorded as a group of indicating units. The relative position of the humidity sensor and the LED display screen is at the center of the LED display screen. When the LED display screen displays colors based on the numbers representing humidity, the display target color is gradually displayed in a gradient form at the position of the relative humidity sensor on the LED display screen, and the color boundary position of the gradual display is applied with smooth transition, intermediate color, blur processing or adding a layer to blend the color boundary position.

[0026] Furthermore, the acquisition module is operated to collect the ceramic membrane water filtration status data displayed on the inspection module, with the color image displayed on the LED display screen in the indicator unit as the acquisition target. During the operation phase of the acquisition module, the color image displayed on the LED display screen is captured by a screenshot tool, and the humidity sensor corresponding to the LED display screen of the color image source is synchronously identified;

[0027] Among them, each group of humidity sensors is provided with a distinguishing mark, and the distinguishing mark set by the humidity sensor can be the deployment location information or digital label of the humidity sensor. After the acquisition module runs to collect the color image and identifies the humidity sensor corresponding to the LED display screen where the color image comes from, the color image is further marked with the distinguishing mark set corresponding to the identified humidity sensor.

[0028] Furthermore, the analysis module is provided with submodules at the lower level, including:

[0029] A logic unit, used to set the analysis logic of the local water filtration performance of the ceramic membrane, and to analyze the local water filtration performance of the ceramic membrane using the analysis logic of the local water filtration performance of the ceramic membrane;

[0030] The analysis logic of the local water filtration performance of the ceramic membrane is expressed as follows:

[0031]

[0032] Where: gu is the number of pixel blocks contained in the gradient color area displayed by the relative position of the u-th group of humidity sensors in the ceramic membrane water filtration state data; u0 is the pixel blocks around the pixel blocks of the relative position of the u-th group of humidity sensors in the ceramic membrane water filtration state data; f(·) is the judgment function; is the color feature vector of the vth group of pixel blocks; α edge is the edge pixel color feature vector of the ceramic membrane water filtration state data; Q is the local water filtration performance value of the ceramic membrane; g max The relative position of the humidity sensor in the ceramic membrane water filtration status data shows the number of pixel blocks in the largest area of ​​the gradient color area; g min The number of pixel blocks in the smallest area of ​​the gradient color area displayed for the relative position of the humidity sensor in the ceramic membrane water filtration status data;

[0033] The larger the performance value Q of the local water filtration performance of the ceramic membrane, the worse the local water filtration performance of the ceramic membrane. Conversely, the better the local water filtration performance of the ceramic membrane. The judgment function f(·) Then f(·) takes the value of 1, and the judgment function f(·) Then the value of f(·) is 0. When the local water filtration performance analysis logic of the ceramic membrane is executed, the ceramic membrane water filtration state data applied is the color image corresponding to the color display result of the LED display screen before the color boundary position of the gradient display is merged.

[0034] Furthermore, when the value of f(·) is 1, the corresponding pixel block is the pixel block included in the gradient color area displayed by the relative position of the humidity sensor in the ceramic membrane water filtration status data, the edge pixel of the ceramic membrane water filtration status data is the pixel block that does not display color, and the gradient color area displayed by the relative position of the humidity sensor obeys. The larger the humidity value, the larger the gradient color area, and vice versa, the smaller the gradient color area.

[0035] Furthermore, during the operation phase of the determination module, the local water filtration performance value Q of the ceramic membrane is obtained synchronously in the logic unit, the local water filtration performance value Q of the ceramic membrane is summed, and then the average is calculated:

[0036]

[0037] Where: Q′ is the performance value of the ceramic membrane water filtration performance; x is the set of local water filtration performance values ​​of the ceramic membrane; Q y is the local water filtration performance value of the ceramic membrane in group y; x0 is the total amount of the local water filtration performance values ​​of the ceramic membrane in set x;

[0038] Among them, two groups of judgment thresholds are set in the judgment module, which are respectively applied to the ceramic membrane water filtration performance value Q′ and the ceramic membrane water filtration performance value K. When any one or two groups of ceramic membrane water filtration performance values ​​are not within the corresponding judgment thresholds, the ceramic membrane is judged to be unqualified; when both groups of ceramic membrane water filtration performance values ​​are within the corresponding judgment thresholds, the ceramic membrane is judged to be qualified.

[0039] Furthermore, during the operation stage of the sniffing module, when it is detected that the judgment result of the judgment module is negative, the local water filtration performance value Q of each ceramic membrane corresponding to the ceramic membrane is obtained, and each group of Q is compared with the judgment threshold used by Q′ in the judgment module. In the water filtration state data of the ceramic membrane corresponding to Q that is not within the judgment threshold, the mark of the relative humidity sensor in the gradient color area is obtained, and the humidity sensor is further determined based on the obtained mark. The surface area of ​​the ceramic membrane relative to the humidity sensor is determined by the humidity sensor, and the surface area of ​​the ceramic membrane, i.e., the location where defects exist on the ceramic membrane surface, is finally determined.

[0040] In a second aspect, a product identification method based on ceramic membrane production comprises the following steps:

[0041] Step 1: Configure the inspection module and collect the ceramic membrane water filtration status data based on the inspection module;

[0042] Step 11: Verify the module operation logic setting stage;

[0043] Step 2: Set the ceramic membrane water filtration state data analysis logic, and analyze the ceramic membrane water filtration performance based on the ceramic membrane water filtration state data analysis logic;

[0044] Step 21: Ceramic membrane water filtration performance analysis logic setting stage;

[0045] Step 3: Obtain the analysis results of the water filtration performance of the ceramic membrane, and determine whether the water filtration performance of the ceramic membrane is qualified based on the analysis results of the water filtration performance of the ceramic membrane;

[0046] Step 4: If the result of step 3 is yes, the process ends and the refresh step is executed;

[0047] Step 5: If the result of step 3 is negative, the defect position on the surface of the ceramic membrane is sniffed;

[0048] Step 51: The setting stage of the ceramic membrane defect position sniffing logic.

[0049] Compared with the known public technology, the technical solution provided by the present invention has the following advantages:

[0050] Beneficial effects:

[0051] The present invention provides a product identification system based on ceramic membrane production. During operation, the system collects analysis data for the water filtration performance of the ceramic membrane by setting a specific inspection module, and then uses the collected data to analyze the water filtration performance of the ceramic membrane in a multi-logic manner, thereby ultimately determining the eligibility of the ceramic membrane, thereby bringing a comprehensive analysis effect to the production of the ceramic membrane, helping to eliminate defective products in the production process of the ceramic membrane, ensuring the quality of the output ceramic membrane, and providing a production safety management effect for the ceramic membrane.

[0052] Furthermore, a product identification method based on ceramic membrane production is further configured to provide further operation logic support for the operation of the above system, ensure the stable operation of the system, monitor the quality of the produced ceramic membranes, and provide protection for the production and use of ceramic membranes.

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] The present invention will be further described below in conjunction with the embodiments.

[0061] Embodiment 1:

[0062] This embodiment is a product identification system based on ceramic film production, such as Figure 1 As shown, including:

[0063] The control terminal is the main control terminal of the system and is used to issue execution commands;

[0064] Inspection module, used to contact the ceramic membrane and display the water filtration status data of the ceramic membrane;

[0065] The inspection module consists of submodules, including:

[0066] The indicating unit is used to indicate the degree of water filtration of the ceramic membrane. When the ceramic membrane leaks out filtered water, it senses the humidity on the surface of the ceramic membrane and shows a color change;

[0067] A pushing unit, used to push the indicating unit to be close to or away from the surface of the ceramic membrane;

[0068] Among them, the indicating unit is integrated with a humidity sensor and an LED display screen. The humidity sensor is pushed by the pushing unit until it is in contact with the surface of the ceramic membrane, and the humidity on the surface of the ceramic membrane is detected. The detected humidity on the surface of the ceramic membrane is represented by a numerical value, and the numerical value representing the humidity is fed back to the LED display screen. The LED display screen is set with display logic. The LED display screen displays the humidity based on the display logic and the received numerical value representing the humidity. During the operation stage of the inspection module, the interior of the ceramic membrane is filled with the liquid to be filtered. After the humidity sensor is pushed by the pushing unit to be in contact with the surface of the ceramic membrane, the liquid injected into the ceramic membrane is pressurized, so that the liquid stored in the porous structure inside the ceramic membrane is filtered through the ceramic membrane and contacts the humidity sensor.

[0069] The acquisition module is used to collect the ceramic membrane water filtration status data displayed on the inspection module;

[0070] An analysis module is used to receive the ceramic membrane water filtration state data collected by the collection module, and analyze the ceramic membrane water filtration performance based on the ceramic membrane water filtration state data;

[0071] The analysis logic of ceramic membrane water filtration performance in the analysis module is expressed as:

[0072]

[0073] Where: k is the difference in water filtration performance of the three groups of ceramic membrane water filtration state data corresponding to the source position; f i 、f i+1 、f i+2 is the average gray value of the i-th, i+1-th and i+2-th groups of ceramic membrane water filtration status data; CITY(i,i+1) is the consistency of the i-th and i+1-th groups of ceramic membrane water filtration status data; CITY(i+1,i+2) is the consistency of the i+1-th and i+2-th groups of ceramic membrane water filtration status data; K is the performance value of the ceramic membrane water filtration performance; m is the set of all groups k of the ceramic membrane water filtration status data obtained based on formula (1); k j is the water filtration performance difference of group j;

[0074] Among them, the larger the ceramic membrane water filtration performance value K is, the worse the ceramic membrane water filtration performance is, and vice versa, the better the water filtration performance is. When the ceramic membrane water filtration status data is used based on formula (1), each set of ceramic membrane water filtration status data is used twice;

[0075] The analysis module is provided with submodules, including:

[0076] A logic unit, used to set the analysis logic of the local water filtration performance of the ceramic membrane, and to analyze the local water filtration performance of the ceramic membrane using the analysis logic of the local water filtration performance of the ceramic membrane;

[0077] The analysis logic of local water filtration performance of ceramic membrane is expressed as:

[0078]

[0079] Where: g u is the number of pixel blocks contained in the gradient color area displayed by the relative position of the u-th group of humidity sensors in the ceramic membrane water filtration state data; u0 is the pixel blocks around the pixel blocks of the relative position of the u-th group of humidity sensors in the ceramic membrane water filtration state data; f(·) is the determination function; is the color feature vector of the vth group of pixel blocks; α edge is the edge pixel color feature vector of the ceramic membrane water filtration state data; Q is the local water filtration performance value of the ceramic membrane; g maxThe relative position of the humidity sensor in the ceramic membrane water filtration status data shows the number of pixel blocks in the largest area of ​​the gradient color area; g min The number of pixel blocks in the smallest area of ​​the gradient color area displayed for the relative position of the humidity sensor in the ceramic membrane water filtration status data;

[0080] The larger the performance value Q of the local water filtration performance of the ceramic membrane, the worse the local water filtration performance of the ceramic membrane. Conversely, the better the local water filtration performance of the ceramic membrane. The judgment function f(·) Then f(·) takes the value of 1, and the judgment function f(·) Then the value of f(·) is 0. When the local water filtration performance analysis logic of the ceramic membrane is executed, the applied ceramic membrane water filtration state data is the color image corresponding to the color display result of the LED display screen before the color boundary position of the gradient display is merged;

[0081] A determination module is used to obtain the analysis results of the water filtration performance of the ceramic membrane in the analysis module, and determine whether the ceramic membrane is qualified based on the analysis results of the water filtration performance of the ceramic membrane;

[0082] A sniffing module is used to monitor the determination result of the determination module, and when the determination result of the determination module is negative, sniff the position where the defect exists on the surface of the ceramic membrane;

[0083] The control terminal is interactively connected to the inspection module through a wireless network, the inspection module is interactively connected to the indication unit and the push unit through a wireless network, the inspection module is interactively connected to the collection module through a wireless network, the collection module is connected to the indication unit through a wireless network, the collection module is interactively connected to the analysis module through a wireless network, the analysis module is interactively connected to the logic unit through a wireless network, the analysis module is interactively connected to the determination module and the sniffing module through a wireless network, and the determination module is interactively connected to the logic unit through a wireless network.

[0084] In this embodiment, the control terminal controls the inspection module to run the contact ceramic membrane, and displays the water filtration status data of the ceramic membrane. The indicator unit synchronously indicates the water filtration degree of the ceramic membrane. When the ceramic membrane leaks and filters water, the humidity on the surface of the ceramic membrane is sensed, and the color changes. The push unit pushes the indicator unit to be close to or away from the surface of the ceramic membrane in real time. The acquisition module further collects the water filtration status data of the ceramic membrane displayed on the inspection module. The analysis module is post-operated to receive the water filtration status data of the ceramic membrane collected in the acquisition module, and the water filtration performance of the ceramic membrane is analyzed based on the water filtration status data of the ceramic membrane. The logic unit synchronously sets the local water filtration performance analysis logic of the ceramic membrane, and the local water filtration performance analysis logic of the ceramic membrane is used to analyze the local water filtration performance of the ceramic membrane. The judgment module then obtains the water filtration performance analysis result of the ceramic membrane in the analysis module, and determines whether the ceramic membrane is qualified based on the water filtration performance analysis result of the ceramic membrane. Finally, the sniffing module monitors the judgment result of the judgment module. When the judgment result of the judgment module is no, the position where there is a defect on the surface of the ceramic membrane is sniffed.

[0085] Through the operation of the system in the above embodiment, a comprehensive quality identification and determination effect is brought to the ceramic membrane, the qualified rate of the produced ceramic membrane is improved, and the functional integrity of the ceramic membrane is guaranteed when the ceramic membrane is used;

[0086] It should be noted that when CITY(i,i+1) and CITY(i+1,i+2) are involved in the logic of ceramic membrane water filtration performance analysis, they refer to the similarity of two sets of ceramic membrane water filtration state data. The similarity is obtained by using any method such as cosine similarity, mean square error, peak signal-to-noise ratio, etc.

[0087] See also Figure 3 As shown, based on the tubular ceramic membrane 1, the push unit 2, the LED display screen 3, and the humidity sensor 4 marked in the figure, the specific structure and distribution posture of the inspection module in the system are further defined and displayed;

[0088] See also Figure 4 As shown, the figure gives an example of a set of ceramic membrane water filtration status data.

[0089] Embodiment 2:

[0090] In terms of specific implementation, based on Example 1, this example refers to Figure 1 A product identification system based on ceramic membrane production in Example 1 is further described in detail:

[0091] The display logic set in the LED display is: set a group of colors, receive the numerical value representing humidity, so that when the LED display receives the numerical value representing humidity, the displayed color is darker, and vice versa, the displayed color is lighter. The color display result of the LED display is the ceramic membrane water filtration status data;

[0092] A group of indicating units and a group of pushing units are recorded as a group of inspection modules. The inspection modules are provided with a plurality of groups, and the plurality of inspection modules are distributed in an equidistant ring shape. When the inspection module contacts the ceramic membrane, the ceramic membrane stands at the center of the inspection module distributed in an annular shape. When the humidity sensor of the inspection module contacts the surface of the ceramic membrane, the sensing end of the humidity sensor is close to the porous inner wall of the ceramic membrane.

[0093] Among them, no less than two groups of humidity sensors and one group of LED display screens are recorded as a group of indicating units. The relative position of the humidity sensor and the LED display screen is at the center of the LED display screen. When the LED display screen displays colors based on the numbers representing humidity, the display target color is gradually displayed in a gradient form at the position of the relative humidity sensor on the LED display screen, and the color boundary position of the gradual display is applied with smooth transition, intermediate color, blur processing or adding a layer to blend the color boundary position.

[0094] Through the above settings, the operating logic of each device in the integrated inspection module is further limited, and with the limited logic, the color image displayed on the LED display screen under the indicator unit in the inspection module is further integrated as before, providing necessary operating data support for the operation of subsequent modules in the system.

[0095] like Figure 1 As shown, the acquisition module runs to collect the ceramic membrane water filtration status data displayed on the inspection module, and takes the color image displayed on the LED display screen in the indicator unit as the acquisition target. During the operation phase of the acquisition module, the color image displayed on the LED display screen is captured by a screenshot tool, and the humidity sensor corresponding to the LED display screen of the color image source is synchronously identified;

[0096] Among them, each group of humidity sensors is provided with a distinguishing mark, and the distinguishing mark set by the humidity sensor can be the deployment location information or digital label of the humidity sensor. After the acquisition module runs to collect the color image and identifies the humidity sensor corresponding to the LED display screen of the color image source, the color image is further marked with the distinguishing mark set corresponding to the identified humidity sensor.

[0097] Through the above settings, the color images collected by the acquisition module are further distinguished and marked, providing further sniffing logic support for the operation of the sniffing module in the system, ensuring that the surface area of ​​the defective ceramic membrane can be accurately sniffed and located.

[0098] like Figure 1As shown in the figure, when the value of f(·) is 1, the corresponding pixel block is the pixel block included in the gradient color area displayed by the relative position of the humidity sensor in the ceramic membrane water filtration status data, and the edge pixel of the ceramic membrane water filtration status data is the pixel block without color display. The relative position of the humidity sensor displays the gradient color area. The larger the humidity value, the larger the gradient color area, and vice versa.

[0099] Through the above settings, the application mode of the analysis logic of the local water filtration performance of the ceramic membrane is further limited, and the display logic of the gradient color area displayed on the LED display screen is further limited.

[0100] like Figure 1 As shown, during the operation phase of the judgment module, the local water filtration performance value Q of the ceramic membrane is obtained synchronously in the logic unit, the local water filtration performance value Q of the ceramic membrane is summed, and then the average is calculated:

[0101]

[0102] Where: Q′ is the performance value of the ceramic membrane water filtration performance; x is the set of local water filtration performance values ​​of the ceramic membrane; Q y is the local water filtration performance value of the ceramic membrane in group y; x0 is the total amount of the local water filtration performance values ​​of the ceramic membrane in set x;

[0103] Among them, two groups of judgment thresholds are set in the judgment module, which are respectively applied to the ceramic membrane water filtration performance value Q′ and the ceramic membrane water filtration performance value K. When any one or two groups of ceramic membrane water filtration performance values ​​are not within the corresponding judgment thresholds, the ceramic membrane is judged to be unqualified. When both groups of ceramic membrane water filtration performance values ​​are within the corresponding judgment thresholds, the ceramic membrane is judged to be qualified.

[0104] During the operation stage of the sniffing module, when it is detected that the judgment result of the judgment module is negative, the local water filtration performance value Q of each ceramic membrane corresponding to the ceramic membrane is obtained, and each group of Q is compared with the judgment threshold used by Q′ in the judgment module. In the water filtration status data of the ceramic membrane corresponding to Q that is not within the judgment threshold, the mark of the relative humidity sensor in the gradient color area is obtained, and the humidity sensor is further determined based on the obtained mark. The surface area of ​​the ceramic membrane relative to the humidity sensor is determined by the humidity sensor, and the surface area of ​​the ceramic membrane, i.e., the location where defects exist on the ceramic membrane surface, is finally determined.

[0105] Through the above settings, the calculation logic of the ceramic membrane water filtration performance value Q′ is limited, and based on the Q′ value, an accurate sniffing principle is provided for the sniffing module to sniff the defect position on the surface of the ceramic membrane.

[0106] Embodiment 3:

[0107] In terms of specific implementation, based on Example 1, this example refers to Figure 2 A product identification system based on ceramic membrane production in Example 1 is further described in detail:

[0108] A product identification method based on ceramic membrane production comprises the following steps:

[0109] Step 1: Configure the inspection module and collect the ceramic membrane water filtration status data based on the inspection module;

[0110] Step 11: Verify the module operation logic setting stage;

[0111] Step 2: Set the ceramic membrane water filtration state data analysis logic, and analyze the ceramic membrane water filtration performance based on the ceramic membrane water filtration state data analysis logic;

[0112] Step 21: Ceramic membrane water filtration performance analysis logic setting stage;

[0113] Step 3: Obtain the analysis results of the water filtration performance of the ceramic membrane, and determine whether the water filtration performance of the ceramic membrane is qualified based on the analysis results of the water filtration performance of the ceramic membrane;

[0114] Step 4: If the result of step 3 is yes, the process ends and the refresh step is executed;

[0115] Step 5: If the result of step 3 is negative, the defect position on the surface of the ceramic membrane is sniffed;

[0116] Step 51: The setting stage of the ceramic membrane defect position sniffing logic.
