A storage method of wheat storage ventilation equipment, using the wheat storage ventilation equipment according to any one of claims 1 to 9, characterized in that: The storage method comprises the following steps: Step 1: First, the wheat to be stored can be poured into the shallow silo body (1) through the feed port (31) on the ventilation top cover (3), and the wheat first enters the feed diversion device (311), and flows into the central feed pipe (16) and the multiple groups of side feed pipes (22) through the feed diversion device (311), and then flows evenly into the shallow silo body (1) through the multiple groups of side feed pipes (22) and the feed port (141) of the central feed pipe (16); Step 2: An integrated intelligent sensor network consisting of external intelligent sensors (11) and internal intelligent sensors (17) is used to continuously monitor the internal and external environmental parameters of the warehouse, including but not limited to key indicators such as temperature, humidity, and air flow speed. Once fluctuations outside the preset threshold are detected, the system automatically activates the ventilation equipment in the corresponding area, and achieves the goal of dynamically balancing temperature and humidity by accurately controlling the fan speed and the opening and closing degree of the vents. The system also predicts the weather trends in the next few days by introducing a machine learning algorithm, and adjusts the ventilation plan in advance, thereby enhancing the system's predictability and ability to respond to emergencies.
