The activation module monitors the performance status of the fiber humidity-conditioning sheet in real time, calculates the current performance xkr of the fiber humidity-conditioning sheet, and analyzes its moisture absorption and dehumidification capacity. When its performance is found to be degraded, 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 warn of the aging process of the fiber humidity-conditioning sheet and promptly inform the user to replace the fiber humidity-conditioning 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 relic storage cabinet is controlled within 1.0%. This standard meets the requirements of the international cultural relic protection field and can effectively prevent the damage to cultural relics caused by humidity fluctuations. 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 relic protection.
