Description

Technical Field

[0001] The utility model belongs to the technical field of earthen site museum protection, and in particular relates to a humidity regulating system for earthen site museums. Background Art

[0002] As an integral part of cultural heritage, earthen sites' preservation environments significantly impact their long-term stability. Humidity is a crucial environmental factor affecting their preservation. Both excessively high and low humidity levels can adversely affect their structural stability and preservation. Currently, museums typically rely on manual humidity monitoring and control, which suffers from delayed response times and low accuracy, making it impossible to accurately and accurately adjust site humidity in real time. More importantly, when designing museums, humidity control should be based on indoor air temperature and humidity, with the layout of related equipment. This regulation is effective for movable cultural relics, but for immovable objects, such as in-situ excavated earthen sites and the Terracotta Army, intelligent humidity control fans in earthen site museums based on infrared image recognition technology often control the fan based on air humidity, thus regulating the air humidity. Due to the large size of these cultural relics and their direct contact with the earthen foundation, their preservation is often ineffective, resulting in frequent damage from alkali reversion and biological damage. In some museums, the damage is even more severe than before the museum was built.

[0003] In order to directly reflect the moisture information of the soil, the existing literature discloses the following technical solutions: The patent application with publication number CN117517304A discloses a: The present invention discloses a method for preparing a humidity fiber optic sensor and an online detection method for the temperature and humidity of an earthen site. The humidity fiber optic sensor responds to the temperature and humidity change information of the earthen site at the same time. When detecting the temperature and humidity of the earthen site online, a temperature compensation unit is introduced to respond to the temperature change information of the earthen site. On the one hand, it can measure the temperature change information of the earthen site, and on the other hand, it can correct the humidity measurement result of the humidity fiber optic sensor; the present invention encapsulates the temperature compensation unit and the humidity fiber optic sensor in a packaging structure, which can not only ensure that the temperature compensation unit and the humidity fiber optic sensor are in full contact with the earthen site, but also isolate the humidity sensitive film on the surface of the humidity fiber optic sensor from adsorbing water molecules in the air, thereby realizing accurate detection of the temperature and humidity of the earthen site. The present invention can be widely used in real-time online and accurate in-situ detection of temperature and humidity in earthen sites, soil, concrete and other fields.

[0004] This application can directly disclose the humidity information in the soil, but the fiber optic sensor needs to be buried in the soil of the earthen site, which will cause certain damage to the earthen site. At the same time, this solution can only obtain the humidity information in the soil. As for the subsequent dehumidification, it is also achieved by starting the fan to directly discharge the indoor moisture, and the protection effect on cultural relics is still not good.

[0005] In summary, the current humidity control of earthen sites has not achieved good results. The reasons are as follows: First, the designers are not clear about the causes of earthen site diseases, and there are large deviations in humidity calculations using the humidity control theory of conventional buildings; second, conventional equipment is based on the actual indoor humidity to turn on the equipment, and when the indoor humidity of the earthen site is high, the earthen site itself has begun to show weathering diseases; third, the humidity of the earthen site is closely related to the soil humidity of the soil foundation, and the weathering of the surface of the earthen site is closely related to the moisture distribution of the earthen site from top to bottom. It is necessary to conduct humidity monitoring, humidity change analysis and timely soil foundation humidity adjustment from a holistic perspective to effectively prevent the deterioration of the earthen site.

[0006] Therefore, a humidity control system for earthen ruins is needed to better protect the earthen ruins. Utility Model Content

[0025] The Humidity Control System for the Earthen Site Museum. The Earthen Site Museum 1 requires relatively high soil humidity. When the humidity exceeds the set value, it is not conducive to the protection of the Earthen Site 1. In this embodiment, the protection of the earthen site is mainly improved by addressing excessive humidity. Specific measures for low humidity are not within the scope of this embodiment and can be implemented using commonly used implementation methods in the prior art.

[0026] like Figure 1As shown, in order to protect the earthen site 1, an earthen foundation 2 is provided along the circumference of the earthen site 1. The earthen site 1 and the earthen foundation 2 are connected. The humidity change of the earthen foundation 2 can cause the humidity change of the earthen site 1. In this way, the humidity of the earthen site 1 can be adjusted by regulating the humidity of the earthen foundation 2, thereby avoiding damage to the earthen site 1, effectively ensuring the integrity of the earthen site 1, and protecting the cultural relics. At the same time, an outer wall 6 is provided along the circumference of the earthen foundation 2.

[0027] This humidity control system Figure 2 As shown, it includes an infrared camera 4, an image recognition chip U4, a central processing unit U1, an exhaust fan, a dehumidification pipe 3 and a connecting pipe.

[0028] The moisture drainage pipes 3 are buried in the soil foundation 2. There are a large number of moisture drainage pipes 3, including a first moisture drainage pipe 3 and a second moisture drainage pipe 3. The first moisture drainage pipe 3 is arranged horizontally in the soil foundation 2, while the second moisture drainage pipe 3 is arranged vertically in the soil foundation 2. The vertical and horizontal arrangements ensure sufficient contact with the soil foundation 2.

[0029] There are holes 7 evenly distributed on the dehumidification pipe 3, wherein the size of the hole 7 is: 0.5mm; the spacing between the holes 7 is 50mm; the holes 7 are set to allow water vapor to pass through, and because the particle size of the soil is often larger than 0.5mm, the soil can be isolated from the outside; on the one hand, air permeability is ensured, and on the other hand, soil is prevented from entering it.

[0030] A connecting pipe, made of PVC, is connected to the moisture removal pipe 3. The end of the connecting pipe is connected to a main exhaust pipe 5, which is installed inside an exterior wall 6. The end of the main exhaust pipe 5 is connected to an exhaust fan, which is installed on the interior ceiling of the museum, with its exhaust port located outside the museum. This exhaust fan exhausts moisture outside the museum.

[0031] When working, the exhaust fan is turned on, and the moisture in the soil is discharged through the exhaust pipe 3, the connecting pipe and the main exhaust pipe 5 through the exhaust fan in sequence, so that the moisture in the soil can be discharged.

[0032] The infrared camera 4 is distributed along the circumference of the earthen site 1 and is set on the earthen foundation 2. To facilitate the installation of the infrared camera 4, a mounting rod is provided on the earthen foundation 2. The infrared camera 4 is installed on the mounting rod and is set toward the earthen site 1 to collect infrared images of the earthen site 1 in real time, which is used to monitor the infrared image of the surface of the earthen site 1 in real time and obtain the surface temperature of the earthen site 1.

[0033] The signal output of infrared camera 4 (FLIR RS6780, manufactured by FLIR Corporation, USA) is connected to image recognition chip U4 (Jetson Xavier NX Developer Kit). Image recognition chip U4 generates temperature data based on the received image information and transmits this temperature data to central processing unit U1 (ESP32-S2). Image recognition chip U4 generates temperature data based on infrared images, which is a mature existing technology and can be used with existing algorithms. This embodiment does not involve any algorithm improvements.

[0034] The USB interface of infrared camera 4 is connected to the pins of image recognition chip U4 via a serial port; image recognition chip U4 communicates with the central processing unit via SPI. Specifically, image recognition chip U4 and the central processing unit can be connected via the SPI interface. During implementation, GPIO pins are selected for both image recognition chip U4 and the central processing unit as the MOSI, MISO, SCK, and CS pins for SPI communication. Infrared camera 4 then transmits the captured image information to image recognition chip U4. Image recognition chip U4 performs temperature recognition based on the received infrared image information and generates temperature information based on the recognized image information. Central processing unit U1 generates humidity information based on the received temperature information and compares the humidity data with an upper threshold. When the humidity information exceeds the upper threshold, central processing unit U1 outputs a signal to activate the exhaust fan.

[0035] In the above scheme, it is necessary to explain that the image recognition chip U4 recognizes the infrared image information received and thus generates corresponding temperature information. The implementation method of this part is a mature existing technology. The image recognition chip U4 can generate temperature information based on the infrared image recognized by the infrared camera 4. Obtaining soil temperature data based on infrared information is a mature existing technology. The central processing unit generates humidity data based on temperature data, which is also a mature existing technology. The relationship between soil temperature and soil humidity is: within a certain temperature range (above 0°C), as the soil temperature increases, the moisture content decreases, such as Figure 4 As shown, according to Figure 4 As shown in the relationship diagram, soil moisture data can be obtained based on the temperature data generated by the infrared image.

[0036] In this embodiment, the central processing unit U1 outputs a signal to control the start-up of the exhaust fan, which is a mature existing technology. As an example, a motor driver chip (model L298N) can be selected, and the signal output end of the central processing unit U1 is connected to the signal input end of the motor driver chip, and the signal output end of the motor driver chip is connected to the exhaust fan, so that the central processing unit U1 outputs a signal to the motor driver chip, and the operation of the exhaust fan can be controlled by the motor driver chip.

[0037] As an alternative to this embodiment, the central processing unit U1 transmits the image information received from the infrared camera 4 and the generated humidity data through its built-in Wi-Fi module. It should be noted that the central processing unit used in this embodiment, model ESP32-S2, has a built-in Wi-Fi function. At the same time, the central processing unit U1 transmits data to the exhaust fan through its own Wi-Fi module, thereby controlling the start and stop of the exhaust fan. The exhaust fan used in this embodiment is a YDF-Z wireless networking type, manufactured by Shanghai Wuling Fan Manufacturing Co., Ltd.

[0038] Meanwhile, a memory stick U2 is connected to the central processing unit U1 for storing data. In this embodiment, the memory stick U2 used is of the model: Solidigm D5-P5336; the manufacturer is Solidigm.

[0039] As an alternative to this embodiment, to ensure the normal operation of the above system, this system also includes a power adapter U3. Power adapter U3 is used to provide power to the system. The power supply of power adapter U3 can come from the mains. The power input end of power adapter U3 is connected to the mains; the power output end of power adapter U3 is connected to the infrared camera 4 and the central processing unit U1, thereby providing power to the infrared camera 4 and the central processing unit U1. In this embodiment, the power adapter selected is a 780W AC model, manufactured by Eurocom.

[0040] The above scheme works as follows: the infrared camera 4 collects image information, transmits the recognized image information to the image recognition chip U4, and the image recognition chip U4 analyzes the temperature data based on the image information; transmits the data to the central processing unit U1, and the central processing unit U1 generates humidity data based on the received temperature data; and compares the humidity data with the upper threshold value;

[0041] When the humidity data is higher than the upper threshold, it means that the humidity in the soil is too high. Then, the central processor U1 outputs a signal to make the exhaust fan work; the moisture enters the hole 7 of the dehumidification pipe 3, enters the connecting pipe through the dehumidification pipe 3, and then enters the main exhaust pipe 5, and finally is discharged from the museum through the exhaust port of the exhaust fan; thereby reducing the humidity in the soil and avoiding excessive humidity in the soil.

[0042] When the humidity value is lower than the lower threshold, it means that the humidity in the soil is too low. This part does not belong to the scope of improvement of this embodiment. In the prior art, when the humidity in the soil is low, the method of increasing the humidity in the air is adopted. This embodiment also adopts the same implementation method as the prior art.

[0043] The utility model discloses a humidity regulation system for an earthen site museum. The system utilizes temperature data to obtain the humidity state in the soil, thereby effectively controlling the actual humidity at the bottom of the soil foundation, and further controlling the moisture content of the earthen site, thereby changing the existing method of controlling air humidity and achieving the purpose of essentially adjusting the humidity of the earthen site.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
