Description

Cultural relics storage environment control method, device and equipment based on intelligent perception

Technical Field

The present application relates to the field of temperature control technology, and specifically to a method, device and equipment for controlling the storage environment of cultural relics based on intelligent perception.

Background Art

With the progress and development of economy and culture, people's awareness of protecting cultural relics has gradually increased, and many methods have been adopted to protect cultural relics. With the continuous development of science and technology, the protection of cultural relics has also moved towards intelligence and automation, and gradually began to use many devices to monitor and control the environment in which cultural relics are stored, further improving the protection effect of cultural relics.

Normally, in order to exhibit similar cultural relics in the same exhibition area, multiple parallel containers or a larger container are usually used for storage. Therefore, in order to more comprehensively monitor the overall temperature changes of the cultural relics storage environment, multiple sensors are used to collect temperature data in the container and transmit it to the cultural relics storage intelligent perception system. The cultural relics storage intelligent perception system uses data anomaly detection algorithms to perform anomaly analysis on temperature data and ultimately determine the current container temperature.

However, when exhibiting cultural relics, the temperature changes in the exhibition hall, the behavior of visitors, etc. will have a certain temperature impact on the glass containers where the cultural relics are stored. Although the impact is weak, for the protection of cultural relics, it is necessary to discover abnormal conditions as early as possible to ensure the timeliness and accuracy of temperature control. The traditional temperature control method for cultural relics storage is not sensitive to subtle changes in the storage temperature of cultural relics, and reacts slowly to such slight changes, resulting in untimely regulation of the storage temperature of cultural relics, which ultimately causes damage to the cultural relics.

In addition, the term "and\or" used herein includes any and all combinations of one or more related listed items. All technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application.

The specific scheme of the cultural relics storage environment control method, device and equipment based on intelligent perception provided by the present application is described in detail below with reference to the accompanying drawings.

Please refer to FIG1 , which shows a flowchart of a method for controlling a cultural relic storage environment based on intelligent perception according to an embodiment of the present application. The method comprises the following steps:

The first step is to collect temperature data from each cultural relic storage glass container in the same exhibition area through a temperature and humidity monitoring and sensing system.

Through the museum's temperature and humidity monitoring and sensing system, the temperature data of each cultural relic storage glass container in the same exhibition area is obtained once every time interval T. In order to avoid data loss during transmission, this application uses a mean filling method to fill in the lost data. Mean filling is a well-known technology, and this application will not repeat its process. In addition, other filling methods can also be used in other embodiments of this application to fill in the lost data.

Among them, the temperature and humidity monitoring and sensing system is a special system used to monitor and manage environmental conditions in real time. It is usually used in places such as museums where temperature and humidity need to be strictly controlled. The temperature and humidity monitoring and sensing system can continuously collect temperature and humidity data of the indoor environment. The system will record historical data, which can be displayed in real time or stored for subsequent analysis.

At the same time, the temperature control device installed in each cultural relic storage glass container is a device and system for managing and adjusting the temperature of the room or the interior of the facility. In this application, the temperature in the cultural relic storage glass container is controlled by the temperature control device according to the temperature control signal. Common temperature control devices include air conditioning systems, heating systems, refrigeration systems, and temperature control controllers. The implementer can select a suitable temperature control device at his/her own discretion, and this embodiment will not be specifically described.

In this embodiment, T is set to 1 minute, and the implementer can set it according to the actual situation.

At this point, the temperature data of each cultural relic storage glass container in the same exhibition area can be collected.

The second step is to analyze the temperature data changes of each cultural relic storage glass container at a single moment to obtain the urgency of temperature control of each cultural relic storage glass container at the corresponding moment.

In one embodiment of the present application, a flow chart of a method for constructing the temperature control urgency is shown in FIG2 , specifically:

A1, for any temperature storage glass container, the temperature data of a single moment and several previous adjacent historical moments are combined into a temperature change state sequence at the corresponding moment.

First, the temperature data of each cultural relic storage glass container at a single moment and several adjacent historical moments before it are combined to form a temperature change state sequence of each cultural relic storage glass container at a single moment. When there are less than 60 moments before a single moment, the mean filling method is used to fill the data, and the mean filling method is a well-known technology and will not be described in detail in this application.

The temperature change state sequence at a single moment can be used to reflect whether an abnormal situation occurs in the previous adjacent historical moments at the corresponding moment, and thus can be used to evaluate the abnormal situation at the corresponding moment.

A2, based on the fluctuation of the temperature change state sequence of each cultural relic storage glass container at a single moment, as well as the similarity and trend intensity difference between the temperature change state sequences of all cultural relic storage glass containers at a single moment, construct the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at a single moment.

Normally, the storage temperature of cultural relics will be affected by the overall temperature of the exhibition hall, but this effect is usually slow, lasts longer, and has a lower impact. During the exhibition, visitors may touch the glass containers or stay in front of a container for a long time, or even violate regulations and use flash to take pictures of cultural relics. These behaviors may affect the storage temperature of cultural relics. Compared with the change of ambient temperature, this kind of impact is faster, lasts for a relatively short time, and has a higher impact.

Based on this, this application constructs a storage temperature fluctuation anomaly coefficient based on the characteristics of changes in ambient temperature data caused by tourist behavior, which in turn affects changes in cultural relics storage temperature data. The flowchart of the construction method of the storage temperature fluctuation anomaly coefficient is shown in Figure 3, specifically:

Among them, the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at a single moment can be determined by the temperature change fluctuation degree and the temperature change time locality of each cultural relic storage glass container at the corresponding moment, that is, the temperature change fluctuation degree of each cultural relic storage glass container at a single moment and the temperature change time locality at the corresponding moment are integrated to obtain the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at the corresponding moment.

As an embodiment of the present application, the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at a single moment is calculated by multiplying the temperature change fluctuation of each cultural relic storage glass container at the corresponding moment by the temperature change time locality at the corresponding moment.

In another embodiment of the present application, the temperature change fluctuation of each cultural relic storage glass container at a single moment is taken as the exponent of an exponential function with a natural constant as the base, and the calculation result of the exponential function and the time locality of the temperature change at the corresponding moment are multiplied as the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at a single moment.

In other embodiments of the present application, the temperature fluctuation of each cultural relic storage glass container at a single moment and the sum of the temperature change time locality at the corresponding moment can be used as the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at the corresponding moment.

It should be understood that the larger the storage temperature fluctuation anomaly coefficient is, the more abnormal the fluctuation of the cultural relic storage temperature is at the current moment, and the more likely it is to have an impact on the cultural relics, requiring certain regulation of the storage temperature of the cultural relics.

The temperature fluctuation of each cultural relic storage glass container at a single moment can be determined by the fluctuation state of the temperature change state sequence of each cultural relic storage glass container at a single moment.

As an embodiment, the temperature variation fluctuation can be obtained by calculating the product between the variance and the range of the temperature variation state sequence.

In other embodiments of the present application, the temperature variation fluctuation may be determined by using the variance or range of the temperature variation state sequence alone.

It should be understood that the greater the fluctuation of temperature changes, the larger the corresponding storage temperature fluctuation anomaly coefficient, which means that the storage temperature of the cultural relics at the current moment and before is changing faster and the amplitude of the change is larger, which is more likely to be caused by the behavior of tourists, and the more it is necessary to regulate the storage temperature of the cultural relics.

Among them, the temporal locality of temperature change at a single moment can be determined by the distance between the temperature change state sequences at a single moment and the similarity of trend intensity between the glass containers storing cultural relics.

As an embodiment, the temporal locality of temperature change at a single moment can be obtained by calculating the product of the distance between the temperature change state sequences of any two cultural relic storage glass containers at a single moment and the trend intensity difference, and summing up the product results of all cultural relic storage glass containers.

In another embodiment of the present application, the distance between the temperature change state sequences can be obtained by calculating the DTW distance between the temperature change state sequences, and in other embodiments of the present application, the inverse of the similarity between the temperature change state sequences can also be used to obtain the distance. Among them, the calculation of the DTW distance is a well-known technology and will not be repeated here, and the similarity can be calculated by using methods such as the Pearson correlation coefficient.

In another embodiment of the present application, the trend strength is obtained by the absolute value of the slope of the fitted line after the temperature change state sequence is linearly fitted. In other embodiments of the present application, the trend strength index can be directly calculated by using the Mann-Kendall trend test, or the trend strength can be calculated by time series analysis. Among them, this embodiment uses the least squares method to perform linear fitting on the temperature change state sequence, and the least squares method is a well-known technology and will not be described in detail.

It should be understood that the greater the temporal locality of the temperature change at a single moment, the greater the corresponding storage temperature fluctuation anomaly coefficient, which means that the temperature changes of the various cultural relics storage glass containers in the same exhibition area at the current moment are less similar, and the more likely it is that the local container temperature changes are caused by visitor behavior, and the more it is necessary to regulate the cultural relics storage temperature.

At this point, the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at each moment can be obtained.

A3. Determine the normal coefficient of storage temperature change at a single moment based on the degree of regular similarity between the temperature change state sequences of all cultural relics storage glass containers at a single moment, the difference in temperature change speed between similar moments, and the periodic intensity of the temperature change state sequences of all cultural relics storage glass containers at a single moment.

However, due to the different popularity of cultural relics exhibited in different exhibition halls, and usually museums have tour guides to lead many tourists to explain the contents of cultural relics, each explanation takes a long time, resulting in a large number of tourists in the exhibition hall for a long time, which will cause the overall temperature of the exhibition hall to rise, and the impact on the storage temperature of cultural relics is closer to the impact of ambient temperature changes. Judging only by the storage temperature fluctuation anomaly coefficient may produce certain errors, so further judgment is needed on this situation.

Under normal circumstances, the change in the storage temperature of cultural relics is mainly affected by the change in ambient temperature. However, since there are temperature control devices in the exhibition hall and the glass containers for storing cultural relics, the change in temperature has a certain regularity and will fluctuate within a local range. However, when the above-mentioned situation of tourists gathering occurs, due to the limitations of the control efficiency and speed of the temperature control equipment, the temperature rise will exceed the normal fluctuation value, the regularity will decrease, and the state of the ambient temperature rise caused by the gathering of tourists also has certain positional differences. Therefore, compared with the change in the storage temperature of cultural relics caused by normal ambient temperature, the change in the storage temperature of cultural relics caused by the gathering of tourists has a relatively low similarity in each glass container for storing cultural relics.

Based on this, this application constructs a storage temperature change normal coefficient according to the characteristics of the impact of tourist gathering on the storage temperature of cultural relics. The flowchart of the construction method of the storage temperature change normal coefficient is shown in Figure 4, which is specifically:

The normal coefficient of storage temperature variation at a single moment can be determined by the approximate coefficient of temperature variation of the cultural relics storage glass container at a single moment and the periodic intensity of the overall temperature variation.

As an embodiment, the storage temperature change normality coefficient at a single moment is determined by multiplying the temperature change approximation coefficient at the corresponding moment by the overall temperature change periodicity intensity.

In another embodiment of the present application, the sum of the temperature change approximation coefficient at a single moment and the overall temperature change periodic intensity can also be used as the storage temperature change normality coefficient at the corresponding moment.

It should be understood that when the normal coefficient of storage temperature change at a single moment is larger, it means that the change state of the cultural relic storage temperature at the current moment is a normal temperature fluctuation, and there is no need to adjust the cultural relic storage temperature temporarily.

For a single moment, a preset number of moments before the single moment is taken as the similar moments of the moment. In this embodiment, the value of the preset number is 10, and the implementer can take the value according to the actual situation. When the preset number of moment data cannot be obtained before a single moment, no analysis and processing is performed on it.

Among them, the approximate coefficient of temperature change at a single moment can be determined by the degree of regular similarity between the temperature change state sequences of all cultural relics storage glass containers at a single moment, and the difference in temperature change rates between similar moments.

As an example, the temperature variation approximate coefficient A can be calculated by a formula, and the specific formula is: ; A is the approximate coefficient of temperature change at a single moment; B is the average value of the PLV values between the temperature change state sequences of all cultural relic storage glass containers at a single moment; D is the average value of the temperature change rate differences between all cultural relic storage glass containers at a single moment and all similar moments; In order to prevent the denominator from being an extremely small positive number of 0, the value is taken as 0.001 in this embodiment.

The temperature change rate can be calculated by the ratio of the temperature extreme difference between similar moments to the time interval between similar moments.

It should be understood that the larger the approximate coefficient of temperature change at a single moment, the larger the corresponding normal coefficient of storage temperature change, which means that the temperature changes in the various cultural relic storage glass containers in the exhibition hall at the current moment are more similar, and the more likely it is that the cultural relic storage temperature has normal changes, and there is no need to adjust the cultural relic storage temperature for the time being.

Among them, the periodic intensity of the overall temperature change at a single moment can be calculated by the average of the periodic intensity of the temperature change state sequence of all cultural relics storage glass containers at a single moment.

It should be understood that the greater the periodic intensity of the overall temperature change at a single moment, the more the overall temperature change of the cultural relic storage glass container at the current moment conforms to the original change law, and the more likely it is that the global change in storage temperature is caused by the gathering of tourists, and the cultural relic storage temperature needs to be regulated.

At this point, the temperature change normality coefficient at each moment can be obtained.

A4, the storage temperature fluctuation abnormal coefficient of each cultural relic storage glass container at a single moment is integrated with the storage temperature change normal coefficient at the corresponding moment to obtain the temperature control urgency of each cultural relic storage glass container at the corresponding moment.

It can be understood that fusion can be divided into forward fusion and reverse fusion. This embodiment adopts the forward fusion method. Forward fusion is a fusion method such as addition and multiplication between data. The specific forward fusion method is determined by the implementer according to the actual situation. The application does not impose any special restrictions.

In one embodiment of the present application, the product of the storage temperature fluctuation abnormal coefficient of each cultural relic storage glass container at a single moment and the storage temperature change normal coefficient at the corresponding moment is used as the temperature control urgency of each cultural relic storage glass container at the corresponding moment.

In another embodiment of the present application, the sum of the storage temperature fluctuation abnormality coefficient of each cultural relic storage glass container at a single moment and the storage temperature change normality coefficient at the corresponding moment is used as the temperature control urgency of each cultural relic storage glass container at the corresponding moment.

In other embodiments of the present application, the storage temperature fluctuation anomaly coefficient of each cultural relic storage glass container at a single moment can be used as the exponent of an exponential function with a natural constant as the base, and the calculation result of the exponential function and the product of the storage temperature change normal coefficient at the corresponding moment can be used as the urgency of temperature control of each cultural relic storage glass container at the corresponding moment.

It should be understood that the greater the urgency of temperature control of each cultural relic storage glass container at a single moment, the greater the possibility that the cultural relic storage temperature at the current moment is abnormal, and the cultural relic storage temperature needs to be regulated in advance.

At this point, the urgency of temperature control of each cultural relic storage glass container at each moment can be obtained.

The third step is to adjust the storage temperature in the glass container for storing cultural relics according to the urgency of temperature control.

Through the second step, the urgency of temperature control of each cultural relic storage glass container at each moment is calculated. This embodiment uses the Otsu threshold algorithm to obtain the segmentation threshold of the urgency of temperature control of all cultural relic storage glass containers at all historical moments. When the urgency of temperature control is greater than or equal to the segmentation threshold, it is considered that the storage temperature of the cultural relic needs to be adjusted at this time.

When the urgency of temperature control of the cultural relics storage glass container at the current moment is greater than or equal to the segmentation threshold, the urgency of temperature control of the cultural relics storage glass container at the current moment and the segmentation threshold are used as inputs of the PID algorithm, and the PID algorithm outputs a temperature adjustment control signal corresponding to the cultural relics storage glass container. The temperature adjustment control signal is used to adjust the temperature of the temperature control device in the cultural relics storage glass container, thereby ensuring the temperature suitability of the cultural relics storage.
