Description

Technical Field

[0001] The present invention relates to the technical field of cultural relics protection, in particular to an energy-saving constant temperature control system for cultural relics storage cabinets. Background Art

[0002] With the advancement of globalization, cultural relic preservation, as a crucial component of cultural heritage protection, has received increasing attention from governments and all sectors of society. Cultural relics carry a wealth of historical information and cultural value, bearing witness to human history and civilization. To effectively protect these precious heritage sites and ensure their long-term preservation and stability, various storage and display technologies are constantly evolving. Temperature and humidity control has become a key factor influencing their preservation. Especially in areas with high humidity and drastic climate change, cultural relics face risks such as moisture and mildew. Therefore, precisely controlling the temperature and humidity of cultural relic storage environments has become a key research focus in the field of cultural relic preservation. Furthermore, with the widespread adoption of energy-saving and environmentally friendly concepts, energy-efficient and intelligent cultural relic storage equipment is becoming a future trend. Such equipment must not only meet the needs of cultural relic preservation but also consider how to effectively reduce energy consumption and achieve environmentally friendly and sustainable development.

[0003] Although existing cultural relics storage cabinets already have basic humidity control functions, they still have some obvious shortcomings and deficiencies. Traditional humidity control methods, especially those based on a single humidity sensor and adjustment system, are often unable to cope with sudden humidity fluctuations in the environment and the performance degradation of the system itself. During long-term use, the fiber moisture-absorbing sheet may fail due to the attenuation of its moisture absorption capacity, resulting in unsatisfactory humidity control effects. In addition, existing humidity control systems usually lack the ability to conduct real-time analysis and dynamic adjustments, making it difficult to accurately predict humidity change trends, and it is not easy to adjust and activate in time when equipment performance deteriorates, causing humidity fluctuations to exceed the set range. These problems not only affect the long-term preservation of cultural relics, but also make it difficult for the energy consumption of cultural relics storage cabinets to achieve optimal energy-saving effects.

[0049] The present invention provides an energy-saving constant temperature control system for cultural relics storage cabinets. It has the following beneficial effects:

[0050] (1) The system collects environmental data in real time through sensor groups installed inside and outside the cultural relics storage cabinet, and transmits it to the purification and constant humidity system through a wireless network. After preprocessing, it forms an environmental stability data group. In this process, the sensor group performs denoising, outlier detection and dimensionless processing on the environmental data to ensure the accuracy and stability of the collected data.

Humidity adjustment not only takes into account the protection needs of cultural relics, but also combines the moisture absorption capacity and performance of the fiber humidity-regulating sheet to ensure that the humidity inside the cultural relic storage cabinet is always stable during the adjustment process. In addition, when the fiber humidity-regulating sheet cannot meet the humidity control requirements, the purification and constant humidity system will compensate by adjusting the humidity Δsys to ensure that the humidity is maintained within the target humidity range inside the cultural relic storage cabinet. This intelligent humidity adjustment strategy not only improves the operating efficiency of the cultural relic storage cabinet, but also reduces the system's energy consumption, thereby maximizing energy saving.

[0052] (3) The activation module and humidity stability analysis module of the system further enhance the intelligence and adaptability of the system. The activation module monitors the performance status of the fiber humidity control sheet in real time, calculates the current performance xkr of the fiber humidity control sheet, and analyzes its moisture absorption and desorption capacity. When its performance is found to have declined, the system automatically starts the activation mode to restore its moisture absorption capacity and ensure the long-term stable operation of the humidity control system. By continuously analyzing humidity data and activation performance, the system can issue early warnings on the aging process of the fiber humidity control sheet and promptly inform the user to replace the fiber humidity control sheet through intelligent diagnosis. In addition, the humidity stability analysis module evaluates the stability of humidity control by calculating the humidity fluctuation coefficient wf and the humidity stability index swd, ensuring that the humidity fluctuation in the cultural relics storage cabinet is controlled within 1.0%. This standard meets the requirements of the international cultural relics protection field and can effectively prevent the damage caused by humidity fluctuations to cultural relics. When the humidity stability index swd is greater than 1.0%, the system will promptly notify the user to perform maintenance or replace the equipment to avoid the adverse effects of humidity control failure on cultural relics protection. This energy-saving constant temperature control system significantly improves the humidity control accuracy and operational efficiency of cultural relic storage cabinets through precise humidity prediction and regulation, real-time performance monitoring and control, and intelligent activation and fault warning. While meeting the professional requirements of cultural relic preservation, it also achieves energy conservation and environmental protection goals, reducing energy consumption and operating and maintenance costs. By combining advanced sensing technology, data processing algorithms, and intelligent control, this system provides an efficient and sustainable solution for cultural relic preservation, with broad application prospects and high market value.

When the current performance xkr of the fiber humidity-conditioning sheet is restored to more than 95% of the initial moisture absorption performance of the fiber humidity-conditioning sheet, the activation mode is stopped and the fiber humidity-conditioning sheet is used for humidity adjustment.

[0100] When the current performance xkr of the fiber humidity-conditioning sheet is greater than 85% of the initial moisture absorption performance state of the fiber humidity-conditioning sheet, the purification and constant humidity system will not start the activation mode and maintain normal monitoring.

[0101] In this embodiment, the activation diagnosis unit can monitor the moisture absorption and release capacity of the fiber humidity-conditioning sheet in real time. When its performance is degraded and the moisture absorption capacity is insufficient, the purification and constant humidity system will automatically determine and start the activation mode to restore the performance of the humidity-conditioning sheet. The activation process is precisely controlled by the real-time calculation of the fiber humidity-conditioning sheet's current performance xkr and humidity adjustment ∆sys, ensuring the sheet operates at optimal conditions. The real-time activation analysis unit continuously monitors the sheet's current performance xkr, combined with its initial moisture absorption capacity, to accurately determine whether activation is complete. It terminates activation mode when the sheet's performance has recovered to above 95%. This design significantly extends the lifespan of the fiber humidity-conditioning sheet, avoiding the cost and maintenance of frequent replacements while also improving the system's automation and adaptability. By ensuring the humidity-conditioning sheet operates at optimal conditions, the system can more efficiently maintain humidity stability within the cultural relic storage cabinets, reducing potential risks to cultural relics from humidity fluctuations and providing a safer, longer-term, and stable preservation environment. This intelligent activation mechanism not only extends the equipment's service life but also optimizes the precision of cultural relic preservation and enhances the overall system's operational efficiency.

[0107] The humidity stability evaluation unit performs humidity fluctuation evaluation and analyzes humidity fluctuation according to the output result of the humidity stability index swd obtained by calculation. The specific evaluation scheme is as follows;

[0108] When the humidity stability index swd ≤ 1.0%, the humidity fluctuation is within the allowable range, indicating that the activation performance of the fiber humidity-conditioning sheet is normal and the humidity in the cultural relics storage cabinet is maintained normally;

[0109] When the humidity stability index swd>1.0%, the humidity fluctuation is not within the allowable range, indicating that the fiber humidity-conditioning sheet is aging. At this time, a replacement message is generated and transmitted to the client of the relevant personnel via the wireless network to notify the relevant personnel to replace it.

[0110] Among them, 1.0% is based on the preservation requirements of cultural relics and the international research and standards on humidity control in the field of cultural relics protection. Through experiments and long-term practical operations, the humidity fluctuation within the cultural relics storage cabinet within 1.0% can effectively ensure the long-term and stable preservation of cultural relics.

[0111] In this embodiment, the humidity stability analysis module ensures that the humidity control effect reaches the optimal level by accurately analyzing and evaluating the humidity fluctuations in the cultural relics storage cabinet.

This standard meets the strict requirements of the international cultural relics protection field. The humidity stability evaluation unit further evaluates the humidity stability index swd. When the humidity fluctuation exceeds 1.0%, the purification and constant humidity system can intelligently generate maintenance reminders and automatically send replacement notifications to the relevant personnel client to ensure that equipment failures and aging problems are handled in a timely manner. This intelligent monitoring and early warning mechanism not only effectively extends the service life of the equipment, but also ensures the long-term stability of the cultural relics storage environment, minimizes human intervention, improves the automation and precision of cultural relics protection, and ensures the safe preservation of cultural relics.
