Description

Technical Field

[0001] The present invention relates to the technical field of denture production, and in particular to a method for controlling a fully enclosed lifting door in a denture production line based on environmental perception. Background Art

[0002] In the denture production line, clean equipment is a special equipment located in the clean workshop, which is used to control the fully enclosed lifting door to build a fully closed-loop airtight environment. By building a fully closed-loop airtight environment, it can effectively prevent pollutants such as dust and microorganisms in the air from entering the clean workshop, ensuring the hygiene and safety of the denture production process.

[0003] During the denture production process, when raw materials, semi-finished dentures or production equipment need to be transported into or out of the clean workshop, the clean equipment needs to control the opening of the lifting door. During this process, since the clean workshop needs to maintain positive pressure to prevent external pollution from invading, the pressure difference drops instantly when the lifting door is opened. If the door speed is too fast, the pressure difference recovery time will be prolonged, which will cause the dust intrusion time window to expand. Therefore, in order to avoid dust intrusion, the clean equipment will dynamically adjust the opening speed of the lifting door based on the dust concentration data in the external environment to avoid rapid opening and closing of the door, which will cause drastic fluctuations in pressure difference, resulting in air backflow and dust pollution.

[0004] In the existing technology, in order to prevent the intrusion of dust, when the dust concentration is high, the clean equipment will dynamically adjust the opening speed of the lifting door based on the dust concentration data to prevent dust from invading the clean workshop. However, the dust concentration cannot fully reflect the pollution risk of dust. The actual pollution risk will also be affected by variables such as environmental factors. Therefore, simply adjusting the opening speed of the lifting door based on the dust concentration is less rational. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figure 1 As shown, in one embodiment, the present application provides a method for controlling a fully enclosed lifting door in a denture production line based on environmental perception, the method comprising: S1: The data acquisition module collects real-time dust concentration data and environmental data near the cleaning equipment after the denture production line starts working; S2: By combining the real-time collected dust concentration data, the real-time dust concentration dispersion coefficient near the cleaning equipment after the denture production line starts working is calculated; S3: By combining the real-time dust concentration dispersion coefficient near the cleaning equipment after the denture production line starts working, analyze whether there is an abnormal increase in dust concentration after the denture production line starts working; S4: By combining the environmental data near the clean equipment after the denture production line starts working and the dust concentration dispersion coefficient, the dust invasion risk of each time the fully enclosed lifting door of the clean equipment is opened is analyzed; S5: Dynamically adjust the opening speed of the fully enclosed lift door of the clean equipment by combining the dust invasion risk analysis results each time the fully enclosed lift door is opened; Through the above technical solution, this example provides a method for controlling a fully enclosed lifting door in a denture production line based on environmental perception. First, the data acquisition module collects in real time the dust concentration data and environmental data near the clean equipment after the denture production line starts working. Then, by combining the real-time collected dust concentration data, the real-time dust concentration dispersion coefficient near the clean equipment after the denture production line starts working is calculated. By combining the real-time dust concentration dispersion coefficient near the clean equipment after the denture production line starts working, it is analyzed whether there is an abnormal increase in dust concentration after the denture production line starts working. Subsequently, by combining the environmental data near the clean equipment after the denture production line starts working and the dust concentration dispersion coefficient, the dust intrusion risk of each time the fully enclosed lifting door of the clean equipment is opened can be analyzed. By combining the dust intrusion risk analysis results each time the fully enclosed lifting door of the clean equipment is opened, the opening speed of the fully enclosed lifting door can be dynamically adjusted. With such a setting, by calculating the real-time dust concentration dispersion coefficient near the clean equipment after the denture production line starts working, it is possible to analyze whether there is an abnormal increase in dust concentration after the denture production line starts working. This data can indirectly reflect whether there are hidden risks. Then, combined with the environmental data, the dust invasion risk of the clean equipment's fully enclosed lifting door is analyzed each time it is opened. This can be achieved based on a multi-parameter collaborative fusion method to improve the accuracy of the dust invasion risk analysis results each time the fully enclosed lifting door of the clean equipment is opened, thereby improving the reliability of the fully enclosed lifting door opening speed adjustment results.

[0023] The environmental data collected in S1 includes: The indoor temperature, indoor humidity and air supply speed of the clean room lift door at any time when it is opened; Through the above technical solution, this example provides environmental data collected in S1, including the indoor temperature, indoor humidity and air supply speed when the clean equipment lifting door is opened at any time. Among them, when the indoor temperature is too high, the Brownian motion of dust particles will be accelerated, and the diffusion range of dust particles will be increased, thereby increasing the risk of dust intrusion into the clean workshop. When the indoor humidity is too low, the electrostatic effect is enhanced, and it is easy to adhere to the outside of the clean equipment lifting door, thereby increasing the risk of dust intrusion into the clean workshop. Finally, when the air supply speed is too high when the clean equipment lifting door is opened at any time, the diffusion range of dust particles will also be increased, thereby increasing the risk of dust intrusion into the clean workshop. When the air supply speed is too low, dust will be attached to the outside of the clean equipment lifting door. Therefore, based on diversified environmental data, diversified data support can be provided for the subsequent analysis of dust intrusion risk to ensure the accuracy of the analysis results, thereby improving the reliability of the subsequent clean equipment lifting door speed control results.

[0024] The calculation process in S2 includes: By formula Calculate the dust concentration dispersion coefficient when the lifting door of the clean equipment is opened for the ath time ; Where a is any opening of the lifting door of the clean equipment after the denture production line starts working, i is a data collection at a fixed time interval, is the total number of data collection times when the lifting door of the clean equipment is opened for the ath time, is the dust concentration near the clean equipment during the i-th data collection, For all The average value of For all The maximum value in For all The minimum value in is the proportionality coefficient, which is set based on the allowable error in the empirical data; Through the above technical solution, this example provides the dust concentration dispersion coefficient when the lifting door of the clean equipment is opened for the ath time , can be obtained by formula The data obtained by calculation can reflect the degree of dispersion of the dust concentration data collected near all clean equipment in the time period from the start of the denture production line to the a-th opening of the clean equipment lifting door. The higher the degree of dispersion, the more abnormal increase in dust concentration occurs during the process, that is, whether there is a hidden risk. By combining this data, additional data support can be provided for the subsequent analysis of the dust intrusion risk at any opening of the clean equipment lifting door, and data support can be provided for the subsequent adjustment of the clean equipment lifting door speed, thereby avoiding the situation where the intrusion risk increases due to abnormal increase in dust concentration.

Compare with the preset dust concentration dispersion coefficient threshold Through this comparison method, we can accurately analyze whether there is an abnormal increase in dust concentration near the clean equipment during the period from the start of the denture production line to the a-th opening of the clean equipment lift door, thereby providing additional data support for the subsequent dust intrusion risk and providing data support for the subsequent adjustment of the clean equipment lift door speed, thereby avoiding the situation where the abnormal increase in dust concentration leads to an increased intrusion risk.

The impact of the numerical range on dust intrusion was obtained through a deep learning model based on a large number of tests; Through the above technical solution, this example provides the dust invasion risk index of the clean equipment lifting door when it is opened for the ath time , can be obtained by formula Calculation shows that, obviously, when the indoor air supply speed when the clean equipment lifting door is opened for the ath time is greater than the preset air supply speed, and the indoor temperature and dust concentration when the clean equipment lifting door is opened for the ath time are higher, and the indoor humidity is lower, then the dust invasion risk index when the clean equipment lifting door is opened for the ath time is higher. On the contrary, when the difference between the indoor air supply speed and the preset air supply speed when the clean equipment lifting door is opened for the ath time is smaller, and the indoor temperature and dust concentration are lower, and the indoor humidity is higher when the clean equipment lifting door is opened for the ath time, then the dust invasion risk index when the clean equipment lifting door is opened for the ath time is higher. Through this calculation method, we can make an accurate analysis of the risk of dust intrusion based on diversified environmental data, thereby providing accurate data for subsequent decision-making on whether to adjust the lifting door of the clean equipment.

On this basis, we can improve the reliability of the opening speed adjustment method of the fully enclosed lift door and the subsequent adjustment results. It should be noted that the above preset dust damage risk index threshold It can be set based on experience fitting.
