Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent regulation and control, and particularly relates to an exhibition permission regulation and control method based on the state of a collection in a museum. BACKGROUND

[0002] With the rapid development of the museum industry, the number of collections is increasing, and the types are becoming more and more complex. In recent years, information technology has developed rapidly, bringing new opportunities for museum collection management. Internet of Things technology, big data technology, cloud computing technology and artificial intelligence technology are emerging and gradually applied in various fields, providing technical support for building intelligent collection management.

[0003] Although some museums have established collection management, these management mostly focuses on basic information management of the collection and electronicization of daily business processes, and the dynamic monitoring and evaluation function of the collection state is relatively weak. Although the in-and-out of the collection can be recorded, there is no effective monitoring and early warning mechanism for the changes of environmental parameters and the development of diseases in the collection during the storage process, and the health status of the collection cannot be grasped in time, so it is difficult to reasonably regulate and control the exhibition permission according to the state of the collection. SUMMARY

[0004] The present application provides an exhibition permission regulation and control method based on the state of a collection in a museum.

[0005] The technical solution of the present application to solve the above technical problems is as follows: an exhibition permission regulation and control method based on the state of a collection in a museum, comprising the following steps:

[0007] S102, according to the temperature and humidity, light intensity and air quality, and combining the sensitivity of the collection to the environment, the environmental suitability level is divided;

[0008] S103, the historical exhibition times, duration and state changes after each exhibition of the collection are counted, and the influence of exhibition on the state of the collection is analyzed;

[0009] S104, according to the comprehensive physical state classification results, environmental suitability level and historical exhibition evaluation results of the collection, the exhibition permission of the collection is regulated and controlled.

[0010] In a preferred embodiment, in step S101, an X-ray fluorescence spectrometer is used to scan the metal artifact to obtain the content data of various elements in the metal artifact. The content of these elements is compared with the known standard composition range to observe the deviation of the element content. For the metal artifact, let n be the types of elements detected, denoted as . Its actual content is The lower limit of the standard content range is The upper limit is The specific formula for calculating its component deviation is as follows: Where i = 1, 2, ..., n, Indicator of component deviation This represents the lower limit of the standard content range for the i-th element. This represents the upper limit of the standard content range for the i-th element. Let represent the actual content of the i-th element. The deviation in element content is used as the basis for judging the stability index of the metal artifact's composition. The specific calculation formula for the composition stability index is as follows: Here, M represents the component stability index. The ceramic is scanned from multiple angles using 3D laser scanning technology to obtain comprehensive point cloud data. A filtering algorithm is used to remove noise points caused by environmental interference and equipment errors. The point cloud data from multiple perspectives are stitched together, and by identifying feature points in overlapping areas, the point cloud data from different perspectives are aligned to form a complete 3D point cloud model of the ceramic. Discontinuities in the point cloud data and the areas where these discontinuities are distributed are searched as areas with structural defects. For a point in point cloud data, its neighborhood set is: The number of neighboring points is m, and the calculation points are... Average distance to neighboring points :

[0011] in, Represents the set of neighborhood points Any neighborhood point in the, Represents its coordinates in three-dimensional space, if Then point Let B be the number of detected discontinuities, and A be the total scanned area of ​​the ceramic. Then, the specific formula for calculating the structural integrity index of the ceramic is as follows: The comprehensive physical condition assessment of the collection is performed by weighted averaging of component stability and structural integrity indicators, assuming... and The weights for component stability and structural integrity are respectively. The specific calculation formula for the comprehensive physical state index is as follows: Where P represents the comprehensive physical state index, when When b < P < a, the physical condition of the collection is good; when b < P < a, the physical condition of the collection is average; when P ≤ b, the physical condition of the collection is fragile.

[0012] In a preferred embodiment, in step S102, temperature and humidity data of the storage environment of the artifacts are collected in real time using a temperature and humidity sensor, light intensity is monitored using a light sensor, and sulfur dioxide, nitrogen oxides, and particulate matter are detected using air quality monitoring equipment. Based on the material and characteristics of the artifacts, the sensitivity of the artifacts to environmental factors related to temperature, humidity, light, and pollutants is scientifically determined. Temperature and humidity suitability index, light suitability index, and comprehensive pollution index are calculated. Let the actual temperature be T, and the lower limit of the suitable lower temperature be... The upper limit of suitable temperature is The actual humidity is H, and the lower limit of suitable humidity is The upper limit of suitable humidity is Temperature suitability index and humidity suitability index The specific determination formula is as follows: .

[0013] Let the actual light intensity be L, and the upper limit of the suitable light intensity be... Then the light suitability index The determination formula is as follows: .

[0014] Assume the actual sulfur dioxide content is The appropriate upper limit for sulfur dioxide content is The actual nitrogen oxide content is The appropriate upper limit for nitrogen oxide content is Actual particulate matter content is The appropriate upper limit for particulate matter content is Calculate their individual indices separately, sulfur dioxide individual index. Nitrogen oxides single index Particulate matter single index Based on the relative importance of each pollutant to the collection, the weight of sulfur dioxide is set as follows: The weight of nitrogen oxides is The weight of particulate matter is Comprehensive Pollution Index The specific calculation formula is as follows: Let the upper limit of the appropriate standard be At that time, When this indicates that the overall condition of these three pollutants in the environment is within a suitable range, it is relatively favorable for the collection. When it is deemed relatively suitable, it means that the overall environment has a certain degree of pollution. If the collection is deemed unsuitable, it means that the overall pollutant content in the environment has exceeded the suitable range for the collection.

[0015] In a preferred embodiment, in step S103, the historical exhibition counts of the collection are comprehensively extracted from the exhibition record database. Duration of each exhibition And data on the changes in status after each exhibition. Based on the status change data and exhibition duration, the exhibition impact coefficient is calculated using the following formula: Let the set of exhibition impact coefficients for all collections be . Where y represents the total number of collections, and the maximum exhibition impact coefficient is set as . Minimum exhibition impact coefficient is For collection type D, the specific formula for calculating its exhibition evaluation weight W is as follows: The exhibition evaluation weight maps the exhibition influence coefficient I to a range of 0-1. A large value of W indicates that the collection needs to be carefully considered when evaluating its exhibition, and that its influence coefficient is large, meaning that the exhibition will have a more significant impact on its status.

[0016] In a preferred embodiment, in step S104, exhibition permissions are adjusted based on the physical condition assessment results, environmental suitability assessment results, and historical exhibition assessment results of the collection. Collections with good physical condition, high environmental suitability, and minimal impact from historical exhibitions are designated as Level 1; collections with average physical condition, relatively suitable environment, and significant impact from historical exhibitions are designated as Level 2; and collections with fragile physical condition, unsuitable environment, and significant changes in condition after historical exhibitions are designated as Level 3. When exhibition planners submit exhibition applications, the system automatically reviews them based on the current permission level of the collection and the conditions for applying for exhibition. Through a visual interface, various status data of the collection are displayed in real time, including physical condition, environmental parameters, and historical exhibition information. When an abnormal status of the collection is detected, an early warning message is sent to the staff, and an emergency response mechanism is activated.

[0017] The beneficial effects of this invention are as follows: Through comprehensive and accurate assessment of the condition of collections, this invention can monitor the physical condition of collections, the suitability of their environment, and the impact of historical exhibitions on them in real time. Environmental suitability assessment ensures that collections are always in an environment with suitable temperature, humidity, light intensity, and air quality, preventing damage caused by environmental factors. These assessment results provide strong evidence for the protection of collections, maximizing their safety. Multiple exhibition permission levels set according to the condition of the collections allow exhibition planners to automatically review applications based on the current permission level and application conditions, greatly saving time and effort compared to manual review. Furthermore, the automatic adjustment of permission levels and notification to relevant personnel after periodic assessments of the collection condition ensures the rationality and timeliness of exhibition arrangements. Historical exhibition data assessment, by calculating exhibition impact coefficients, provides important references for subsequent exhibitions. Collections with high impact coefficients are given higher weight in subsequent exhibition assessments. This prompts museums to develop more reasonable exhibition plans and protection measures based on the characteristics and condition of different collections, thereby optimizing cultural relic protection work.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

The following description is provided to enable any person skilled in the art to make and use the invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0022] like Figure 1 This embodiment provides: an exhibition permission control method based on the status of museum collections, specifically including the following steps: S101, using spectral analysis of the composition of metal artifacts, using three-dimensional laser scanning technology to detect the structure and surface condition of ceramics, and classifying the collections according to the physical state based on the detection results;

[0023] Furthermore, X-ray fluorescence spectrometry was used to scan the metal artifacts to obtain the content data of various elements in the artifacts. The content of these elements was compared with known standard composition ranges to observe any deviations. For the metal artifacts, let n be the number of detected elements, denoted as _n_. Its actual content is The lower limit of the standard content range is The upper limit is The specific formula for calculating its component deviation is as follows: Where i = 1, 2, ..., n, Indicator of component deviation This represents the lower limit of the standard content range for the i-th element. This represents the upper limit of the standard content range for the i-th element. Let represent the actual content of the i-th element. The deviation in element content is used as the basis for judging the stability index of the metal artifact's composition. The specific calculation formula for the composition stability index is as follows: Here, M represents the component stability index. The ceramic is scanned from multiple angles using 3D laser scanning technology to obtain comprehensive point cloud data. A filtering algorithm is used to remove noise points caused by environmental interference and equipment errors. The point cloud data from multiple perspectives are stitched together, and by identifying feature points in overlapping areas, the point cloud data from different perspectives are aligned to form a complete 3D point cloud model of the ceramic. Discontinuities in the point cloud data and the areas where these discontinuities are distributed are searched as areas with structural defects. For a point in point cloud data, its neighborhood set is: The number of neighboring points is m, and the calculation points are... Average distance to neighboring points :

[0025] It should be noted that in the calculation of the ceramic structural integrity index, 1 represents the baseline quantity, used to construct a relative calculation system to better reflect the degree of ceramic structural integrity. It can be understood as a theoretical ideal state of integrity. Since the number of discontinuous points B will have a negative impact on structural integrity, subtracting B from 1 will yield a value that is positively correlated with structural integrity. This value is then divided by the total scan area A for normalization, so that the index S can reflect the relative level of ceramic structural integrity within a reasonable range.

Nitrogen oxides single index Particulate matter single index Based on the relative importance of each pollutant to the collection, the weight of sulfur dioxide is set as follows: The weight of nitrogen oxides is The weight of particulate matter is Comprehensive Pollution Index The specific calculation formula is as follows: Let the upper limit of the appropriate standard be At that time, When this indicates that the overall condition of these three pollutants in the environment is within a suitable range, it is relatively favorable for the collection. When it is deemed relatively suitable, it means that the overall environment has a certain degree of pollution. If the collection is deemed unsuitable, it means that the overall pollutant content in the environment has exceeded the suitable range for the collection.

[0030] S103. Statistically analyze the number of times and duration of historical exhibitions of the collection, as well as the changes in the condition of the collection after each exhibition, and analyze the impact of exhibitions on the condition of the collection.

[0031] Furthermore, the historical number of exhibitions of the collections was comprehensively extracted from the exhibition record database.

Collections with good physical condition, high environmental suitability, and minimal impact from historical exhibitions are classified as Level 1. Collections with average physical condition, relatively suitable environment, and significant impact from historical exhibitions are classified as Level 2. Collections with fragile physical condition, unsuitable environment, or significant changes in condition after historical exhibitions are classified as Level 3. When exhibition planners submit exhibition applications, the system automatically reviews them based on the current permission level of the collection and the conditions for applying for exhibition. Through a visual interface, various status data of the collections are displayed in real time, including physical condition, environmental parameters, and historical exhibition information.
