Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a real-time collection method and system for silica gel production data. Background Art

[0002] In the prior art, silica gel is a common material widely used in the fields of industry and consumer goods. It is made of silicon dioxide and water through a special process. Silica gel is a material with stable chemical properties and good physical properties. Due to its advantages, it is widely used in various fields. In the process of producing silica gel, it is necessary to collect data such as temperature, pressure, flow rate, etc. of the production equipment in real time to ensure the normal operation of silica gel production.

[0003] Chinese Patent Publication No.: CN108898278A discloses a production line data automatic collection system and method, the system includes a material frame and a material tray, characterized in that it also includes a middleware data platform, a warehouse management system, an MES and an automated testing system, a radio frequency identification tag is installed at the bottom of the material tray, and a radio frequency identification reader is installed at the bottom of the production line, and the middleware data platform is used for data processing and analysis; the radio frequency identification tag is used to record the corresponding product information on the material tray, and when passing through a workstation equipped with a radio frequency identification reader, the radio frequency identification reader reads the tag information and uploads it to the middleware data platform, and the middleware data platform processes the obtained information and transmits it to the MES to update the production status corresponding to the product, or provide product information to the automated testing system to realize the automated testing function. It can be seen from this that the production line data automatic collection system and method have the problem that the current is unstable due to possible failure of the production equipment, resulting in unstable power supply voltage, which in turn causes the sensor to collect inaccurate data, thereby causing the stability of real-time collection to decrease. Summary of the invention

[0004] To this end, the present invention provides a real-time collection method and system for silica gel production data, so as to overcome the problem in the prior art that possible failure of production equipment leads to unstable current, unstable power supply voltage, and further leads to inaccurate data collection by sensors, thereby reducing the stability of real-time collection.

[0005] To achieve the above-mentioned purpose, the present invention provides a real-time collection method for silicone production data, comprising: collecting silicone production data in real time, and transmitting the silicone production data to a storage location; monitoring the silicone production data in real time, and issuing an alarm when it exceeds a safety range; respectively obtaining the number of successful silicone production data collections and the total number of silicone production data collections within a number of collection cycles; judging whether the stability of real-time collection meets the requirements based on the variance of the proportion of the number of successful silicone production data collections; if the stability does not meet the requirements, adjusting the collection threshold value of the silicone production data or determining the collection effectiveness of the silicone production data based on the average packet loss rate of the silicone production data; if the collection effectiveness does not meet the requirements, adjusting the number of silicone production data transmission nodes or adjusting the density of test sampling points based on the average difference of the silicone production data.

[0006] Further, determining the stability of the real-time acquisition includes: The number of successful silicone production data collections and the total number of silicone production data collections in several collection cycles are obtained respectively, and the variance of the proportion of successful silicone production data collections is calculated; Comparing the variance of the percentage of successful times of silica gel production data collection with a preset first variance; If the variance of the percentage of successful times of collecting the silica gel production data is greater than the preset first variance, it is determined that the stability of the real-time collection does not meet the requirements.

[0007] Further, determining the validity of the collection of the silica gel production data includes: Comparing the variance of the percentage of the number of successful silica gel production data collection with the preset first variance and the preset second variance; If the variance of the proportion of the number of successful collection of the silicone production data is greater than the preset first variance and less than or equal to the preset second variance, it is preliminarily determined that the collection validity of the silicone production data does not meet the requirements, and a secondary determination is made on whether the collection validity of the silicone production data meets the requirements based on the average packet loss rate of the silicone production data.

[0008] Furthermore, the collection threshold value of the silica gel production data is adjusted, including: Comparing the variance of the percentage of the number of successful silica gel production data collection with the preset second variance; If the variance of the percentage of successful times of collecting the silicone production data is greater than the preset second variance, the collection threshold value of the silicone production data is increased.

[0009] Furthermore, the increase range of the collection threshold value of the silicone production data is determined by the difference between the variance of the percentage of the number of successful silicone production data collections and a preset second variance.

[0010] Further, the number of the silica gel production data transmission nodes is adjusted, including: Obtain the packet loss rate of the silica gel production data in several transmission cycles, and calculate the average packet loss rate of the silica gel production data; Comparing the average packet loss rate of the silica gel production data with a preset first packet loss rate and a preset second packet loss rate respectively; If the average packet loss rate of the silica gel production data is greater than the preset first packet loss rate, it is determined that the collection validity of the silica gel production data does not meet the requirements; If the average packet loss rate of the silica gel production data is greater than the preset first packet loss rate and less than or equal to the preset second packet loss rate, then increasing the number of silica gel production data transmission nodes; If the average packet loss rate of the silicone production data is greater than the preset second packet loss rate, it is preliminarily determined that the environmental stability of the silicone production data collection does not meet the requirements, and a secondary determination is made on whether the environmental stability of the silicone production data collection meets the requirements based on the average difference in the silicone production data.

[0011] Furthermore, the increase in the number of the silica gel production data transmission nodes is determined by the difference between an average packet loss rate of the silica gel production data and a preset first packet loss rate.

[0012] Further, the density of the test sampling points is adjusted, including: Obtain the silicone production data under the same environment for several times, and calculate the average difference of the silicone production data; Comparing the average difference of the silica gel production data with a preset difference; If the average difference of the silica gel production data is greater than the preset difference, it is determined that the environmental stability of the silica gel production data collection does not meet the requirements, and the density of the test sampling points is increased.

[0013] Furthermore, the increase range of the density of the test sampling points is determined by the difference between the average difference amount of the silica gel production data and the preset difference amount.

[0014] The present invention also provides a real-time collection system for silica gel production data, comprising: A data acquisition module, comprising a data acquisition unit for acquiring silica gel production data and a data transmission unit connected to the data acquisition unit for transmitting the silica gel production data to a storage location; A storage module, connected to the data acquisition module, for storing the silica gel production data; An alarm module, which is connected to the data acquisition module and is used to issue an alarm when the silica gel production data exceeds a safe range; A control module is respectively connected to the data acquisition module, the storage module and the alarm module, and is used to determine whether the stability of real-time collection meets the requirements based on the variance of the proportion of the number of successful silicone production data collections, and to adjust the collection threshold value of the silicone production data when it does not meet the requirements, or to adjust the number of silicone production data transmission nodes based on the average packet loss rate of the silicone production data, and to adjust the density of test sampling points based on the average packet loss rate of the silicone production data and the average difference of the silicone production data.

[0015] Compared with the prior art, the beneficial effect of the present invention lies in that the method of the present invention adjusts the collection threshold value of silicone production data according to the variance of the proportion of the number of successful silicone production data collection. Since the production equipment may fail, resulting in unstable current, unstable power supply voltage, and inaccurate data collection by the sensor, the stability of real-time collection is reduced. By increasing the collection threshold value of silicone production data, a certain degree of data fluctuation can be allowed without triggering erroneous data collection or processing operations, which can reduce error data caused by current instability and improve the stability and accuracy of data collection. The number of silicone production data transmission nodes is adjusted according to the average packet loss rate of silicone production data. Since the factory producing silicone The site is large and the signal transmission distance is long. During the signal transmission process, metal structures or walls may be encountered, resulting in a decrease in signal quality, which in turn causes the loss of some data packets. By increasing the number of silicone production data transmission nodes, the signal coverage range is improved and the possibility of signal interference during transmission is reduced. The density of the test sampling points is adjusted according to the average difference in silicone production data. Since there are many devices used to produce silicone, the temperature of the environment increases during the production process, which causes delays in the data transmission process and differences in data collection. By increasing the density of the test sampling points, more data points can be obtained in the same time, reducing the uncertainty caused by data differences and delays, and improving the stability of real-time collection.

[0016] Furthermore, the method of the present invention adjusts the collection threshold value of silicone production data by setting a preset first variance and a preset second variance. Since the production equipment may malfunction, resulting in unstable current and unstable power supply voltage, which in turn leads to inaccurate data collection by the sensor, the stability of real-time collection is reduced. By increasing the collection threshold value of silicone production data, a certain degree of data fluctuation can be allowed without triggering erroneous data collection or processing operations, which can reduce error data caused by current instability, improve the stability and accuracy of data collection, and further improve the stability of real-time collection.

[0017] Furthermore, the method of the present invention adjusts the number of silicone production data transmission nodes by setting a preset first packet loss rate and a preset second packet loss rate. Since the factory site for producing silicone is large and the signal transmission distance is long, metal structures or walls may be encountered during the signal transmission process, resulting in a decrease in signal quality, thereby causing some data packets to be lost. By increasing the number of silicone production data transmission nodes, the signal coverage range is improved, the possibility of signal interference during transmission is reduced, and the stability of real-time acquisition is further improved.

[0018] Furthermore, the method of the present invention adjusts the density of the test sampling points by setting a preset difference amount. Since a large number of devices are used to produce silicone, the temperature of the environment increases during the production process, which causes delays in the data transmission process and produces differences in data collection. By increasing the density of the test sampling points, more data points can be obtained in the same time, reducing the uncertainty caused by data differences and delays, and further improving the stability of real-time collection.

[0024] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, they are respectively an overall flow chart of the real-time collection method and system of silica gel production data according to an embodiment of the present invention, an overall structure block diagram, a logic flow chart, and a specific flow chart for adjusting the collection threshold value of silica gel production data. A real-time collection method for silica gel production data according to the present invention comprises: Step S1, collecting silica gel production data in real time and transmitting the silica gel production data to a storage location; Step S2, real-time monitoring of the silica gel production data, and issuing an alarm when it exceeds a safe range; Step S3, respectively obtaining the number of successful silica gel production data collection and the total number of silica gel production data collection in a number of collection cycles; Step S4, judging whether the stability of real-time data collection meets the requirements based on the variance of the percentage of successful times of silica gel production data collection; Step S5, if the stability does not meet the requirement, adjusting the collection threshold value of the silica gel production data or determining the collection validity of the silica gel production data based on the average packet loss rate of the silica gel production data; Step S6: If the collection effectiveness does not meet the requirements, the number of silica gel production data transmission nodes is adjusted or the density of test sampling points is adjusted based on the average difference of silica gel production data.

[0025] Specifically, the silicone production data includes the temperature of the production equipment, the pressure of the production equipment, and the flow rate of silicone in the production equipment.

[0026] Specifically, the safety range includes the temperature of the production equipment being less than or equal to 300°C, the pressure of the production equipment being less than or equal to 15MPa, and the flow rate of silicone in the production equipment being less than or equal to 200L / min.

[0027] Specifically, successful collection of silicone production data means that the collected silicone production data does not experience data packet loss or erroneous data.

[0028] Specifically, the collection threshold value of silicone production data is a standard threshold value that triggers the collection of silicone production data.

[0029] Specifically, the test sampling point is a test point used to verify the association between one parameter and another parameter, so as to find out the association relationship between the two parameters under the environmental conditions.

[0030] Specifically, the density of the test sampling points is the number of samples of the test sampling points per unit time.

[0031] Specifically, if the correlation between the reaction temperature and the product curing time in the silicone production process is to verify the correlation between the reaction temperature and the product curing time, the test process of the test sampling point is to set temperature sensors at key parts of the silicone production equipment, such as around the extruder and near the heating device, as sampling points for the reaction temperature, and set marking points at certain intervals on the conveyor belt for product output. When the product passes through these marking points, the time is recorded as the sampling point for the product curing time. At the same time, an independent third-party testing equipment, such as a hygrometer, is introduced and placed in a position where the ambient humidity can be easily detected as a test sampling point; the production of silicone products begins, and the temperature sensor monitors the reaction temperature in real time and transmits the data to the data acquisition system. When the product passes through the marking point on the conveyor belt, the timer is triggered to record the time, and the third-party testing equipment detects the ambient humidity at that moment when the product passes through the marking point; the test is continuously carried out within a certain period of time, and a large amount of temperature, curing time and humidity data pairs are collected. The data is sorted, outliers and erroneous data are removed, and a scatter plot of the relationship between the reaction temperature, product curing time and ambient humidity is drawn. Statistical analysis methods, such as calculating correlation coefficients and performing regression analysis, are used to determine the specific correlation between the reaction temperature and the product curing time.

[0032] In implementation, the method of the present invention adjusts the collection threshold value of silicone production data according to the variance of the proportion of the number of successful silicone production data collection. Since the production equipment may malfunction, resulting in unstable current, unstable power supply voltage, and inaccurate data collection by the sensor, the stability of real-time collection is reduced. By increasing the collection threshold value of silicone production data, a certain degree of data fluctuation can be allowed without triggering erroneous data collection or processing operations, which can reduce error data caused by current instability and improve the stability and accuracy of data collection. The number of silicone production data transmission nodes is adjusted according to the average packet loss rate of silicone production data. Since the factory site for silicone production is large, the signal The transmission distance is long, and metal structures or walls may be encountered during signal transmission, resulting in a decrease in signal quality, which in turn causes the loss of some data packets. By increasing the number of silicone production data transmission nodes, the signal coverage is improved and the possibility of signal interference during transmission is reduced. The density of the test sampling points is adjusted according to the average difference in silicone production data. Since there are many devices used to produce silicone, the temperature of the environment increases during the production process, which causes delays in the data transmission process and differences in data collection. By increasing the density of test sampling points, more data points can be obtained in the same time, reducing the uncertainty caused by data differences and delays, and improving the stability of real-time collection.

[0033] Specifically, determining the stability of the real-time acquisition includes: The number of successful silicone production data collections and the total number of silicone production data collections in several collection cycles are obtained respectively, and the variance of the proportion of successful silicone production data collections is calculated; Comparing the variance of the percentage of successful times of silica gel production data collection with a preset first variance; If the variance of the percentage of successful times of collecting the silica gel production data is greater than the preset first variance, it is determined that the stability of the real-time collection does not meet the requirements.

[0034] Specifically, determine the effectiveness of collecting data on silica gel production, including: Comparing the variance of the percentage of the number of successful silica gel production data collection with the preset first variance and the preset second variance; If the variance of the proportion of the number of successful collection of the silicone production data is greater than the preset first variance and less than or equal to the preset second variance, it is preliminarily determined that the collection validity of the silicone production data does not meet the requirements, and a secondary determination is made on whether the collection validity of the silicone production data meets the requirements based on the average packet loss rate of the silicone production data.

[0035] It can be understood that the three intervals corresponding to the preset first variance Q1 and the preset second variance Q2 correspond to three situations respectively. The first interval is Q≤Q1, corresponding to the situation where the stability of real-time acquisition meets the requirements; the second interval is Q1<Q≤Q2, corresponding to the factory site of silicone production is large, the signal transmission distance is long, and metal structures or walls may be encountered during the signal transmission process, resulting in a decrease in signal quality, thereby causing some data packets to be lost; the third interval is Q>Q2, corresponding to the situation where the production equipment may fail, resulting in unstable current, unstable power supply voltage, and inaccurate data collection by the sensor. In practice, the range of Q1 is generally selected from [0.82, 0.84], and the range of Q2 is generally selected from [0.84, 0.86].

[0036] Preferably, the first variance Q1 is preset to be 0.83, and the second variance Q2 is preset to be 0.85.

[0037] Specifically, the variance of the percentage of successful silicone production data collection is recorded as Q.

[0038] Specifically, the variance of the percentage of successful times of silicone production data collection is the variance of the percentage of successful times of silicone production data collection within several collection cycles. The calculation method of the variance of the percentage of successful times of silicone production data collection is a conventional technical means well known to technical personnel in this field. Therefore, the calculation process of the variance of the percentage of successful times of silicone production data collection will not be repeated here.

[0039] Specifically, the calculation formula for the percentage of successful silicone production data collection is: , Among them, T is the percentage of successful silicone production data collection, K1 is the number of successful silicone production data collection in several collection cycles, and K2 is the total number of silicone production data collection in several collection cycles.

[0040] In implementation, the method of the present invention determines the stability of real-time acquisition by setting a preset first variance and a preset second variance, thereby reducing the impact of reduced accuracy of real-time acquisition due to inaccurate determination of the stability of real-time acquisition, and further improving the stability of real-time acquisition.

[0041] Specifically, the collection threshold value of the silica gel production data is adjusted, including: Comparing the variance of the percentage of the number of successful silica gel production data collection with the preset second variance; If the variance of the percentage of successful times of collecting the silicone production data is greater than the preset second variance, the collection threshold value of the silicone production data is increased.

[0042] Specifically, the increase range of the collection threshold value of the silicone production data is determined by the difference between the variance of the proportion of the number of successful silicone production data collections and a preset second variance.

[0043] Specifically, the calculation formula for the collection threshold value of the increased silica gel production data is: , Among them, V' is the increased collection threshold value of silicone production data, V is the current collection threshold value of silicone production data, A is the minimum unit variance for adjusting the collection threshold value of silicone production data, and v is the collection threshold value of silicone production data when the variance of the proportion of successful silicone production data collection times is the minimum unit variance.

[0044] In practice, the value of A is generally 0.89 to 0.91, and preferably, the preferred embodiment of A is 0.9.

[0045] In implementation, the optional range of v is [4A, 6A]. Preferably, when the collection threshold value of silica gel production data is less than 5A, inaccurate data collection may occur. Therefore, the preferred embodiment of v is 5A.

[0046] Specifically, in this scheme, the collection threshold value of silicone production data is selected as the working current of the production equipment.

[0047] Specifically, when the value of V' is a decimal, the value of V' is automatically rounded up to one decimal place.

[0048] For example, the real-time data collection method of silica gel production is used to collect data of the silica gel production process, where V = 4.5A, Q = 0.98, and V' = ≈5.3A.

[0049] In implementation, the method of the present invention adjusts the collection threshold value of silicone production data by setting a preset first variance and a preset second variance. Since the production equipment may malfunction, resulting in unstable current and unstable power supply voltage, which in turn leads to inaccurate data collection by the sensor, the stability of real-time collection is reduced. By increasing the collection threshold value of silicone production data, a certain degree of data fluctuation can be allowed without triggering erroneous data collection or processing operations, which can reduce error data caused by current instability, improve the stability and accuracy of data collection, and further improve the stability of real-time collection.

[0050] Specifically, adjusting the number of the silica gel production data transmission nodes includes: Obtain the packet loss rate of the silica gel production data in several transmission cycles, and calculate the average packet loss rate of the silica gel production data; Comparing the average packet loss rate of the silica gel production data with a preset first packet loss rate and a preset second packet loss rate respectively; If the average packet loss rate of the silica gel production data is greater than the preset first packet loss rate, it is determined that the collection validity of the silica gel production data does not meet the requirements; If the average packet loss rate of the silica gel production data is greater than the preset first packet loss rate and less than or equal to the preset second packet loss rate, then increasing the number of silica gel production data transmission nodes; If the average packet loss rate of the silicone production data is greater than the preset second packet loss rate, it is preliminarily determined that the environmental stability of the silicone production data collection does not meet the requirements, and a secondary determination is made on whether the environmental stability of the silicone production data collection meets the requirements based on the average difference in the silicone production data.

[0051] It can be understood that the three intervals corresponding to the preset first packet loss rate P1 and the preset second packet loss rate P2 correspond to three situations respectively. The first interval is P≤P1, which corresponds to the situation that the collection validity of silicone production data meets the requirements; the second interval is P1<P≤P2, which corresponds to the situation that the factory site for silicone production is large and the signal transmission distance is long. During the signal transmission process, metal structures or walls will be encountered, resulting in a decrease in signal quality, thereby causing some data packets to be lost; the third interval is P>P2, which corresponds to the situation that there are many silicone production equipment, resulting in an increase in the temperature of the environment during the production process, which leads to delays in the data transmission process and differences in data collection. In practice, the range of P1 is generally selected from [0.07, 0.09], and the range of P2 is generally selected from [0.11, 0.13].

[0052] Preferably, the preferred embodiment of the preset first packet loss rate P1 is 0.08, and the preferred embodiment of the preset second packet loss rate P2 is 0.12.

[0053] Specifically, the average packet loss rate of silica gel production data is denoted as P.

[0054] Specifically, the average packet loss rate of silica gel production data is calculated as follows: , Where P is the average packet loss rate of silica gel production data, X a is the packet loss rate of silica gel production data in the ath transmission cycle, n is the number of transmission cycles, and n is a natural number greater than or equal to 1.

[0055] In implementation, the method of the present invention performs a secondary judgment on the effectiveness of the collection of silicone production data by setting a preset first packet loss rate and a preset second packet loss rate, thereby reducing the impact of the decreased stability of real-time collection due to inaccurate secondary judgment on the effectiveness of the collection of silicone production data, and further improving the stability of real-time collection.

[0056] Specifically, the increase in the number of the silica gel production data transmission nodes is determined by the difference between the average packet loss rate of the silica gel production data and the preset first packet loss rate.

[0057] Specifically, the calculation formula for the number of increased silicone production data transmission nodes is: , Among them, H' is the increased number of silicone production data transmission nodes, H is the current number of silicone production data transmission nodes, B is the minimum unit packet loss rate for adjusting the number of silicone production data transmission nodes, and h is the number of silicone production data transmission nodes when the average packet loss rate of silicone production data is the minimum unit packet loss rate.

[0058] In practice, the value of B is generally 0.14 to 0.16, and preferably, the preferred embodiment of B is 0.15.

[0059] In implementation, the optional range of the value of h is [4, 6]. Preferably, when the number of silica gel production data transmission nodes is less than 5, data packets may be lost. Therefore, the preferred embodiment of h is 5.

[0060] Specifically, when the value of H' is a decimal, the value of H' is automatically rounded up to an integer.

[0061] For example, the real-time data collection method of silica gel production is used to collect data from the silica gel production process, where H = 4, P = 0.13, and H' = ≈6.

[0062] In implementation, the method of the present invention adjusts the number of silicone production data transmission nodes by setting a preset first packet loss rate and a preset second packet loss rate. Since the factory site for producing silicone is large and the signal transmission distance is long, metal structures or walls may be encountered during the signal transmission process, resulting in a decrease in signal quality, thereby causing some data packets to be lost. By increasing the number of silicone production data transmission nodes, the signal coverage range is improved, the possibility of signal interference during transmission is reduced, and the stability of real-time acquisition is further improved.

[0063] Specifically, adjusting the density of the test sampling points includes: Obtain the silicone production data under the same environment for several times, and calculate the average difference of the silicone production data; Comparing the average difference of the silica gel production data with a preset difference; If the average difference of the silica gel production data is greater than the preset difference, it is determined that the environmental stability of the silica gel production data collection does not meet the requirements, and the density of the test sampling points is increased.

[0064] It can be understood that the two intervals corresponding to the preset difference amount Y0 correspond to two situations. The first interval is Y≤Y0, which corresponds to the situation where the environmental stability of silicone production data collection meets the requirements; the second interval is Y>Y0, which corresponds to the situation where there are many silicone production equipment, resulting in an increase in the temperature of the environment during the production process, which leads to delays in the data transmission process and differences in data collection. In practice, the range of Y0 is generally [8℃, 12℃].

[0065] Preferably, the preset difference Y0 is 10°C.

[0066] Specifically, the difference in the silica gel production data in this solution is the temperature collected by the production equipment at different times.

[0067] Specifically, the average difference in silica gel production data is recorded as Y.

[0068] Specifically, the average difference in silica gel production data is calculated as: , Among them, Y is the average difference of silica gel production data, E f -E f-1 is the difference between the temperature of the processing equipment under the same environment for the fth time and the temperature of the processing equipment under the same environment for the f-1th time, i is the number of times the temperature of the processing equipment is collected, and i is a natural number greater than or equal to 2.

[0069] In implementation, the method of the present invention performs a secondary judgment on the environmental stability of silicone production data collection by setting a preset difference amount, thereby reducing the impact of the decreased stability of real-time collection due to inaccurate secondary judgment on the environmental stability of silicone production data collection, and further improving the stability of real-time collection.

[0070] Specifically, the increase in the density of the test sampling points is determined by the difference between the average difference amount of the silica gel production data and the preset difference amount.

[0071] Specifically, the calculation formula for the density of the increased test sampling points is: , Among them, L' is the density of the test sampling points after the increase, L is the density of the current test sampling points, C is the minimum unit difference for adjusting the density of the test sampling points, and l is the density of the test sampling points when the average difference of the silicone production data is the minimum unit difference.

[0072] In practice, the value of C is generally 11°C to 13°C, and preferably, the preferred embodiment of C is 12°C.

[0073] In implementation, the optional range of l is [3 / minute, 5 / minute]. Preferably, when the density of test sampling points is less than 4 / minute, it may cause differences in data collection. Therefore, the preferred embodiment of l is 4 / minute.

[0074] For example, the real-time data collection method of silica gel production is used to collect data of the silica gel production process, where L = 3 pieces / minute, Y = 16°C, and L' = =5 pieces / minute.

[0075] In implementation, the method of the present invention adjusts the density of the test sampling points by setting a preset difference amount. Since a large number of devices are used to produce silicone, the temperature of the environment increases during the production process, which causes delays in the data transmission process and produces differences in data collection. By increasing the density of the test sampling points, more data points can be obtained in the same time, reducing the uncertainty caused by data differences and delays, and further improving the stability of real-time collection.
