[0002] Cultural relics are extremely susceptible to environmental factors such as temperature, humidity, light, and air quality. Changes in these factors can cause irreversible damage to cultural relics. The state of cultural relics is closely related to the environment.

The intensity and duration of light directly affect the color and surface quality of cultural relics. Air pollutants can cause chemical corrosion of cultural relics.

[0028] Figure 1 Fig. 1 is a first flowchart of a cultural relic environment monitoring method provided by an embodiment of the present application. The embodiment can be applicable to the case of quantifying the environmental risk of cultural relics according to multi-dimensional environmental parameters and the change of multi-dimensional environmental parameters over time. The method can be executed by a cultural relic environment monitoring device, which can be realized in the form of hardware and / or software, and can be configured in an electronic device with corresponding data processing capability. As shown in Fig. 1, the method comprises: Figure 1

[0029] S110, determining a single-parameter risk level corresponding to the current environmental parameter according to the monitoring value of the current environmental parameter at any time.

[0030] Each single-parameter risk level has its preset parameter value range. Among them, the environmental parameter and the parameter value range corresponding to each single-parameter risk level of the environmental parameter are determined according to the cultural relic attribute; the cultural relic attribute includes cultural relic grade, material, climate zone and state; wherein, the state includes repair, storage, exhibition and transportation.

[0031] ​The cultural relic grades can include first-grade cultural relics, second-grade cultural relics, third-grade cultural relics, and the like. The climate zones include severe cold regions, cold regions, hot summer and cold winter regions, hot summer and warm winter regions, and temperate regions. The cultural relic materials include paper, bamboo, wooden lacquerware, textiles, metal, and porcelain, and the like. Different environmental parameters can be selected according to different cultural relic attributes; further, the parameter value ranges of the single-parameter risk grades of the same environmental parameter can be different according to different cultural relic attributes.

[0032] Each single-parameter risk grade has a preset parameter value range. The environmental parameters are divided into interval expansion classification parameters and non-overlapping classification parameters according to the parameter value ranges corresponding to the single-parameter risk grades. The interval expansion classification parameter refers to a specific expected range, which is set as the parameter range of the single-parameter risk grade with the minimum risk. On this basis, as the risk increases, the preset parameter value range of the single-parameter risk grade is gradually relaxed based on the parameter value range of the single-parameter risk grade with the minimum risk. This parameter classification method is mainly based on the deviation degree from the expected value. The smaller the deviation from the expected range, the lower the risk grade; the larger the deviation, the higher the risk grade. The non-overlapping classification parameter refers to dividing the entire parameter value range into several non-overlapping intervals, each interval corresponding to a single-parameter risk grade.

[0033] The temperature and humidity parameter belongs to the interval expansion classification parameter. If the environmental parameter is the temperature and humidity parameter, the parameter value range of the single-parameter risk grade with the minimum risk is the expected environmental parameter range of the cultural relic, and as the risk increases, the preset parameter value range of the single-parameter risk grade is gradually relaxed based on the parameter value range of the single-parameter risk grade with the minimum risk. For example, if the environmental parameters to be monitored of a cultural relic include temperature and humidity, the expected relative humidity range of the cultural relic is 45-50% RH, and the expected temperature range is 18-20°C, the parameter value range of the first single-parameter risk grade with the minimum risk corresponding to the temperature and humidity environmental parameter is (18-20°C, 45-50% RH); the parameter value ranges of the second single-parameter risk grade and the third single-parameter risk grade are gradually relaxed based on the parameter value range of the first single-parameter risk grade, which are set as (17-21°C, 42-52% RH) and (16-22°C, 40-55% RH), respectively.

[0034] If the environmental parameter is a non-overlapping classification parameter, the higher the risk grade, the larger the threshold value of the parameter value range of the corresponding single-parameter risk grade. For example, if the environmental parameter is the sulfur dioxide concentration, the parameter value range of the first single-parameter risk grade with the minimum risk is less than 15 μg / m 3 ; the parameter value range of the second single-parameter risk grade is 15-50 μg / m 3 ; and the parameter value range of the third single-parameter risk grade is 50-150 μg / m 3; the parameter value range of the fourth single-parameter risk level is 150-500 μg / m 3 ; the parameter value range of the fifth single-parameter risk level is greater than 500 μg / m 3 .

[0035] Taking a first-grade painted clay sculpture cultural relic in a cold region and during an exhibition as an example, how to determine the environmental parameters that need to be monitored according to the properties of the cultural relic and the parameter value range of each single-parameter risk level corresponding to each environmental parameter is illustrated.

[0036] The cultural relic is a national first-grade cultural relic, which determines that it should follow the most stringent environmental risk evaluation. If it is a second-grade or third-grade cultural relic, the parameter value range of the single-parameter risk level of the first-grade cultural relic can be relaxed by 5% level by level;

[0037] The environmental parameters that need to be monitored for the first-grade painted clay sculpture cultural relic in a cold region and during an exhibition include temperature and humidity, illuminance, ultraviolet intensity, sulfur dioxide concentration and formic acid concentration

[0038] The temperature and humidity environmental parameter corresponds to five single-parameter risk levels, and the parameter value ranges of temperature and humidity corresponding to the single-parameter risk levels from low to high are (18-20℃, 45-50%RH), (17-21℃, 42-52%RH), (16-22℃, 40-55%RH), (16-25℃, 40-60%RH) and (15-30℃, ≥60%RH) respectively.

[0039] The illuminance environmental parameter corresponds to five single-parameter risk levels, and the parameter value ranges corresponding to the single-parameter risk levels from low to high are (0-50lx), (50-75lx), (75-100lx), (100-125lx) and greater than 125lx) respectively.

[0040] The ultraviolet intensity corresponds to five single-parameter risk levels, and the parameter value ranges corresponding to the single-parameter risk levels from low to high are daily cumulative dose <0.004 mJ / cm 2 , daily cumulative dose 0.004-0.4 mJ / cm 2 , daily cumulative dose 0.4-2 mJ / cm 2 , daily cumulative dose 2-12 mJ / cm 2 , daily cumulative dose >12 mJ / cm 2 .

[0041] The sulfur dioxide concentration corresponds to five single-parameter risk levels, and the parameter value ranges corresponding to the single-parameter risk levels from low to high are less than 15 μg / m 3 , 15-50 μg / m 3 , 50-150 μg / m 3 , 150-500 μg / m3 ; greater than 1.0 mg / m 3 ;

[0042] The formic acid concentration corresponds to five single-parameter risk levels, and the parameter value ranges corresponding to the single-parameter risk levels from low to high are: less than 0.001 mg / m 3 ; 0.001-0.01 mg / m 3 ; 0.01-0.1 mg / m 3 ; 0.1-1.0 mg / m 3 ; greater than 1.0 mg / m 3 ;

[0043] If the state of the cultural relics changes to transportation, the vibration monitoring replaces the illumination monitoring. The vibration parameter corresponds to five single-parameter risk levels, and the parameter value ranges corresponding to the single-parameter risk levels from low to high are: acceleration <0.01 m / s 2 (approximately static environment); acceleration 0.01-0.1 m / s 2 ; acceleration 0.1-0.5 m / s 2 ; acceleration 0.5-1.0 m / s 2 ; acceleration >1.0 m / s 2 .

[0044] If the environmental parameter is an interval extension classification parameter, the single-parameter risk level corresponding to the current environmental parameter is determined according to the monitoring value of the current environmental parameter at any time, which includes: judging whether the monitoring value is within the parameter value range of the single-parameter risk level in order from low to high, and once it is determined that the monitoring value is within the parameter value range of a single-parameter risk level, it is determined that the single-parameter risk level corresponds to the current environmental parameter.

[0045] If the environmental parameter is a non-overlapping classification parameter, the single-parameter risk level corresponding to the current environmental parameter is determined according to the monitoring value of the current environmental parameter at any time, which includes: clearly defining the parameter value range pre-set for each single-parameter risk level, and if the monitoring value is within the parameter value range pre-set for a single-parameter risk level, it is determined that the single-parameter risk level corresponds to the current environmental parameter.

[0046] S120, according to the duration and frequency of each single-parameter risk level of the current environmental parameter within the time window, determining the dynamic single-parameter risk of the current environmental parameter within the time window.

[0047] The single-parameter risk level reflects the judgment of the risk caused by the current environmental parameter to the cultural relics at a certain moment. A time window is selected to determine the single-parameter risk level of the current environmental parameter appearing in the time window. According to the duration and frequency of each single-parameter risk level of the current environmental parameter in the time window, the dynamic single-parameter risk of the current environmental parameter in the time window is determined. The dynamic single-parameter risk combines the change amplitude, frequency, trend and correlation of the instantaneous influence (single-parameter risk level) of the environmental parameter on the cultural relics over time to determine the judgment of the risk caused by the current environmental parameter to the cultural relics due to the change of the environment over time within a certain time.

[0048] In S130, the multi-factor comprehensive risk of the cultural relics in the time window is determined according to the dynamic single-parameter risk of each environmental parameter in the time window.

[0049] The dynamic single-parameter risk reflects the judgment of the risk caused by the single environmental parameter to the cultural relics due to the change of the environment over time within a certain time. The multi-factor comprehensive risk of the cultural relics in the time window is determined according to the dynamic single-parameter risk of each environmental parameter in the time window. Specifically, a weight is set for each environmental parameter, and the dynamic single-parameter risks of the environmental parameters in the time window are weighted and summed to obtain the multi-factor comprehensive risk of the cultural relics in the time window. The weight of the environmental parameter is set according to the sensitivity of the cultural relics to different environmental parameters. The multi-factor comprehensive risk reflects the risk caused by the change of each environmental parameter over time to the cultural relics, and further reflects the risk influence of the interaction between multiple environmental parameters on the cultural relics. Specifically, it is shown in the following formula (1):

[0050]

[0051] Wherein, R represents the multi-factor comprehensive risk of the cultural relics in the time window; n represents the number of environmental parameters corresponding to the cultural relics; Ω i represents the weight of the environmental parameter i; R i represents the dynamic single-parameter risk of the environmental parameter i.

[0052] The embodiment of the present application determines the single-parameter risk level corresponding to the current environmental parameter according to the monitoring value of the current environmental parameter at any time; determines the dynamic single-parameter risk of the current environmental parameter in the time window according to the duration and the change frequency of each single-parameter risk level of the current environmental parameter in the time window; and determines the multi-factor comprehensive risk of cultural relics in the time window according to the dynamic single-parameter risk of each environmental parameter in the time window. The cultural relic grade, material, climate zone and environmental sensitive characteristics in different states such as repair, storage, exhibition and transportation are deeply fused, the parameter value range corresponding to the environmental parameter and the single-parameter risk level of the environmental parameter is determined according to these cultural relic properties, and then the single-parameter risk level at any time is determined based on real-time monitoring data, and the dynamic single-parameter risk is obtained by comprehensively considering the duration and the change frequency of each single-parameter risk level in the time window, which fuses the risk information caused by the change amplitude, frequency and trend of the instantaneous influence (single-parameter risk level) of the environmental parameter on the cultural relics over time, and finally integrates the dynamic single-parameter risk of each environmental parameter to determine the multi-factor comprehensive risk of cultural relics. The environmental monitoring and evaluation data model is constructed, which is synchronized with time, traceable and multi-dimensional data correlated, can accurately, comprehensively and dynamically evaluate the environmental risk of cultural relics, and provides a scientific basis for cultural relic protection.

[0053] In an optional embodiment, the determination of the dynamic single-parameter risk of the current environmental parameter in the time window according to the duration and the change frequency of each single-parameter risk level of the current environmental parameter in the time window comprises: acquiring the single-parameter risk level of the current environmental parameter at each collection time in the time window; determining the duration of the single-parameter risk level i in the time window according to the collection time corresponding to the single-parameter risk level i; determining the duration proportion of the single-parameter risk level i in the time window according to the duration and the length of the time window; determining the number of level transitions of the single-parameter risk level i in the time window and the total number of level transitions of each single-parameter risk level in the time window; wherein the number of level transitions corresponding to the single-parameter risk level i is the number of transitions from the single-parameter risk level i to other single-parameter risk levels; determining the change frequency of the single-parameter risk level i according to the number of level transitions of the single-parameter risk level i in the time window and the total number of level transitions of each single-parameter risk level in the time window; and determining the dynamic single-parameter risk of the current environmental parameter in the time window according to the level weight of each single-parameter risk level, the duration proportion of each single-parameter risk level and the change frequency of each single-parameter risk level.

[0054] The duration of the single-parameter risk level i in the time window is accumulated to determine the duration of the single-parameter risk level i in the time window. The ratio of the duration of the single-parameter risk level i in the time window to the length of the time window is taken as the duration proportion of the single-parameter risk level i in the time window. The ratio of the number of times of the single-parameter risk level i in the time window to the total number of times of the single-parameter risk level in the time window is taken as the change frequency of the single-parameter risk level i, that is, the frequency of the cross-level from the i-th single-parameter risk level. Wherein, for the current environmental parameter, if it is switched from any single-parameter risk level to other single-parameter risk level, it is recorded as a cross-level. The specific formula (2) is as follows:

[0055]

[0056] Wherein: R A represents the dynamic single-parameter risk of the current environmental parameter A in the time window; A represents the current environmental parameter; n A represents the number of levels of the single-parameter risk level corresponding to the current environmental parameter; a Ai represents the weight of the i-th single-parameter risk level of the current environmental parameter A, and the sum of a Ai =1; t Ai represents the duration proportion of the single-parameter risk level i of the current environmental parameter A in the time window; f Ai represents the cross-level frequency of the current environmental parameter A in the time window from the i-th single-parameter risk level.

[0057] By determining the duration of the single-parameter risk level i in the time window and the length of the time window, the duration proportion of the single-parameter risk level i in the time window is determined. According to the number of times of the single-parameter risk level i in the time window and the total number of times of the single-parameter risk level in the time window, the change frequency of the single-parameter risk level i is determined. According to the level weight of each single-parameter risk level, the duration proportion of each single-parameter risk level, and the change frequency of each single-parameter risk level, the dynamic single-parameter risk of the current environmental parameter in the time window is determined. The change amplitude, frequency, trend and correlation of the instantaneous influence of the environmental parameter on the cultural relics (single-parameter risk level) with time are fused to determine the risk of the cultural relics caused by the change of the environment with time within a certain time, rather than the risk influence of the single statistical moment of the environmental parameter on the cultural relics, so as to improve the quantitative evaluation, early warning and control optimization level of the cultural relics protection risk.

[0058] Figure 2A It is a second flowchart of a cultural relic environmental monitoring method provided by the embodiment of the application. The embodiment is optimized and improved on the basis of the above-mentioned embodiment. As shown in Figure 2A , the method comprises:

[0059] S210, determining a single-parameter risk level corresponding to the current environmental parameter according to a monitoring value of the current environmental parameter at any time.

[0060] The environmental parameters and the parameter value ranges corresponding to each single-parameter risk level of the environmental parameters are determined according to the cultural relic attributes; the cultural relic attributes include cultural relic grades, materials, climate zones and states; the states include repair, storage, exhibition and transportation.

[0061] S220, determining a dynamic single-parameter risk of the current environmental parameter within a time window according to the duration and frequency of change of each single-parameter risk level of the current environmental parameter within the time window.

[0062] S230, determining a multi-factor comprehensive risk of the cultural relic within the time window according to the dynamic single-parameter risks of each environmental parameter within the time window.

[0063] The environmental parameters at least include temperature and humidity parameters; the method further comprises:

[0064] S240, visualizing the monitoring values of each environmental parameter of the current cultural relic and the single-parameter risk levels corresponding to the monitoring values in a three-dimensional coordinate system.

[0065] Optionally, the temperature and humidity parameters include dry-bulb temperature and relative humidity; the three-dimensional coordinate system includes dry-bulb temperature, moisture content and time; the moisture content is obtained by enthalpy-humidity calculation of the monitoring relative humidity; the method further comprises:

[0066] determining the monitoring values of the dry-bulb temperature and the relative humidity at any time t, and the single-parameter risk levels of the dry-bulb temperature and the relative humidity corresponding to the monitoring values;

[0067] determining the first dry-bulb temperature, the second dry-bulb temperature, the first relative humidity and the second relative humidity corresponding to the single-parameter risk level, and determining the first moisture content and the second moisture content corresponding to the first relative humidity and the second relative humidity;

[0068] for the time t, in a two-dimensional coordinate system constructed by taking the moisture content as the X-axis and the dry-bulb temperature as the Y-axis, a first relative humidity line and a second relative humidity line are drawn according to the first relative humidity and the second relative humidity; a curved quadrilateral region is drawn according to the first relative humidity line, the second relative humidity line, the first dry-bulb temperature and the second dry-bulb temperature;

[0069] The curved quadrilateral areas corresponding to different time points are arranged in sequence in the time coordinate axis direction, and the position and area of the curved quadrilateral area dynamically change with the single-parameter risk level corresponding to the monitoring values of the dry-bulb temperature and the relative humidity at different time points, and finally a three-dimensional graph capable of intuitively representing the change of the single-parameter risk level of the dry-bulb temperature and the relative humidity over time is formed.

[0070] As shown in Figure 2B The environmental parameters at least include temperature and humidity parameters; the temperature and humidity parameters include the dry-bulb temperature and the relative humidity, and the absolute humidity, the moisture content, the water vapor partial pressure, and the related dew point temperature, the wet-bulb temperature, the heat-moisture ratio, and the specific volume can be calculated according to the dry-bulb temperature and the relative humidity; a three-dimensional coordinate system is constructed with the moisture content as the X-axis, the dry-bulb temperature as the Y-axis, and the time as the Z-axis.

[0071] For any time point t, the moisture content is determined according to the monitoring value of the relative humidity; the single-parameter risk level of the dry-bulb temperature and the relative humidity is determined according to the monitoring values of the dry-bulb temperature and the relative humidity, the parameter value range corresponding to the single-parameter risk level is determined, and the parameter value range includes the first dry-bulb temperature, the second dry-bulb temperature, the first relative humidity, and the second relative humidity. The first dry-bulb temperature and the second dry-bulb temperature are the lower limit and the upper limit of the temperature value of the single-parameter risk level respectively; the first relative humidity and the second relative humidity are the lower limit and the upper limit of the humidity value of the single-parameter risk level respectively. The first relative humidity and the second relative humidity correspond to the first moisture content and the second moisture content.

[0072] For the time point t, in the two-dimensional coordinate system constructed with the moisture content as the X-axis and the dry-bulb temperature as the Y-axis,

[0073] The first equal relative humidity line and the second equal relative humidity line are drawn according to the first relative humidity and the second relative humidity; a curved quadrilateral area is drawn according to the first equal relative humidity line, the second equal relative humidity line, the first dry-bulb temperature, and the second dry-bulb temperature. According to the monitoring values of the dry-bulb temperature and the relative humidity at different time points, the single-parameter risk level of the corresponding dry-bulb temperature and relative humidity, the corresponding curved quadrilateral area is determined.

[0074] The curved quadrilateral areas corresponding to different time points are arranged in sequence in the time coordinate axis direction, and the position and area of the curved quadrilateral area dynamically change with the single-parameter risk level corresponding to the monitoring values of the dry-bulb temperature and the relative humidity at different time points, and finally a three-dimensional graph capable of intuitively representing the change of the single-parameter risk level of the dry-bulb temperature and the relative humidity over time is formed.

[0075] Further, the actual value of any two of the absolute humidity, the moisture content, the water vapor partial pressure, the dew point temperature, the wet bulb temperature, the heat-moisture ratio, and the specific volume of the air at the time t can be determined according to the dry bulb temperature and the relative humidity, and the single-parameter risk level and the parameter value range corresponding to the single-parameter risk level are determined, and a curvilinear quadrilateral region is plotted in a two-dimensional coordinate system constructed by the X-axis and the Y-axis according to the parameter value range.

[0076] A three-dimensional coordinate system is constructed by the moisture content, the dry bulb temperature, and the time, and a curvilinear quadrilateral region corresponding to the single-parameter risk level of the air temperature and humidity environment parameters at different times is plotted in a two-dimensional coordinate system constructed by the X-axis and the Y-axis according to the monitoring values of the air temperature and humidity environment parameters at different times and the single-parameter risk level of the air temperature and humidity environment parameters. The curvilinear quadrilateral regions corresponding to different times are arranged in sequence in the direction of the time coordinate axis, and the position and area of the curvilinear quadrilateral region dynamically change with the single-parameter risk level corresponding to the monitoring values of the air temperature and humidity environment parameters at different times, and finally a three-dimensional graph is formed which can intuitively represent the change of the single-parameter risk level of the air temperature and humidity environment parameters with time. In a three-dimensional, intuitive, and dynamic visual form, the originally abstract and dispersed changes of the air temperature and humidity environment parameters and their single-parameter risk levels with time are clearly presented, which facilitates the observer to quickly and comprehensively grasp the dynamic evolution trend of the air temperature and humidity environment risk, timely discover the potential risk period and abnormal change, and provide intuitive and powerful basis for environmental monitoring, risk assessment, and corresponding control decision, greatly improving the efficiency of information processing and the scientificity of decision-making.

[0077] Optionally, the color of each side of the curvilinear quadrilateral region is used to represent the single-parameter risk level of an environment parameter, and a color system corresponding to each environment parameter is specified. For each side of the curvilinear quadrilateral region, the color depth of the side is determined according to the single-parameter risk level of the environment parameter corresponding to the side, and if the single-parameter risk level of the environment parameter changes, the color depth of the corresponding side will also be adjusted accordingly, so as to intuitively reflect the presentation effect of the curvilinear quadrilateral region of different environment parameters at different risk levels through color.

[0078] Based on the artifact's attributes, four environmental parameters with the highest sensitivity (excluding temperature and humidity) can be selected. The color of one edge of a curved quadrilateral region reflects the risk level of a single environmental parameter; the color intensity represents the change in risk level over time. As time progresses, the curved quadrilateral region forms a three-dimensional graphic, consisting of four faces parallel to the time axis, each face appearing as a color band with varying intensity. Rotating the three-dimensional graphic reveals each face. Figure 2B As shown, yellow represents sulfur dioxide concentration, and blue represents ultraviolet radiation intensity. The shade of color represents the risk level of a single environmental parameter.

[0079] This method associates the color of each edge of a curved quadrilateral region with the risk level of a single environmental parameter, assigning a corresponding color scheme to each parameter and determining the edge color intensity based on the risk level. The color intensity adjusts as the risk level changes. This highly intuitive and visual approach integrates the risk level information of different environmental parameters into the presentation of the curved quadrilateral region. Observers do not need complex analysis or calculations; simply by viewing the color and intensity changes of each edge of the curved quadrilateral region, they can quickly and clearly understand the risk level of each environmental parameter at different times. This allows for the rapid detection of risk level fluctuations and anomalies, significantly improving the efficiency and accuracy of information acquisition and providing simple and effective visualization support for environmental risk assessment and decision-making.

[0080] Optionally, when the three-dimensional graphic is set to a transparent state, a line graph is drawn to represent the changes in the monitored values ​​of temperature and humidity monitoring parameters over time; wherein, the color of the line graph represents the state of the cultural relic.

[0081] The 3D graph is set to transparent, and a line graph is drawn to represent the changes in the monitored values ​​of temperature and humidity parameters over time. The colors of the line segments in the line graph can represent the different states of the cultural relics, such as: green - storage; blue - restoration; yellow - exhibition; red - transportation.

[0082] By setting the 3D graphics to a transparent state and plotting line graphs to represent the changes in temperature and humidity monitoring parameters over time, different colored line segments are used to distinguish the status of the cultural relics. On the one hand, the transparent 3D graphics allow observers to simultaneously focus on the three-dimensional dynamic changes in the risk level of temperature and humidity environmental parameters and the line trend of temperature and humidity monitoring values, presenting more comprehensive information. On the other hand, by intuitively identifying the status of the cultural relics through different colored line segments, the specific changes in temperature and humidity under different conditions can be quickly identified, facilitating comparative analysis of the relationship between each status and temperature and humidity. This helps to promptly identify potential risks and provides accurate and efficient decision-making basis for environmental control of cultural relics under different conditions.

[0083] The embodiment of the present application presents information in a three-dimensional, intuitive and comprehensive manner by visualizing the monitoring values of the current cultural relic environment parameters and the corresponding single-parameter risk levels in a three-dimensional coordinate system, integrates the originally scattered and abstract environmental parameter data and risk level information in a three-dimensional space, and enables the observer to quickly grasp the correlation and difference between different environmental parameters, clearly see the dynamic change trend of the monitoring values of each parameter and the fluctuation of the corresponding risk level, accurately locate the high-risk period and parameter combination, quickly identify potential risk hazards, and provide comprehensive, accurate and efficient visual basis for cultural relic environment regulation and protection decision-making, thereby greatly improving the scientificity and timeliness of the decision-making.
