The method includes continuously collecting environmental parameters such as thermodynamic parameters, humidity parameters, and gas concentration parameters through intelligent sensing nodes at multiple locations within the green building; transmitting these environmental parameters to a central processing unit, which combines pre-stored environmental standard values ​​with real-time data streams and uses an adaptive learning algorithm to generate environmental control commands; environmental execution devices carrying out environmental adjustment activities based on these commands; real-time monitoring of the execution sequence of adjustment activities, calculation of performance evaluation indicators, and generation of normal or abnormal performance status signals, automatically triggering an alarm process in case of an anomaly. This method constructs a complete environmental management closed loop, realizing comprehensive dynamic monitoring and precise adjustment of the green building environment, adapting to the core requirements of environmental protection and comfort in green buildings, and ensuring that the building's internal environment is in a suitable state.

The application provides a detection frequency adjustment method for an archive warehouse device and related equipment, and relates to the technical field of intelligent operation and maintenance of archive warehouse devices. The method comprises the following steps: calculating an environmental deviation amplitude of a current environmental parameter in the archive warehouse relative to a preset environmental standard value; calculating a maintenance demand index and an archive vulnerability index according to the environmental deviation amplitude, a device fault risk level of a target component and an archive sensitivity level; obtaining a time correction step length based on an index difference value mapping; if the maintenance demand index is greater than or equal to the archive vulnerability index, the time correction step length is deducted from the remaining waiting time length of the current detection cycle, so that the next detection action is performed in advance; otherwise, the time correction step length is added to the remaining waiting time length of the current detection cycle, so that the next detection action is delayed. The method can ensure that the mechanical performance of the device is in a controlled state while reducing the physical damage risk caused by the action performed during the archive fragile period.
